UNC 140 provides the function with GSM BSC equivalence, and controls one or more (virtual) UMA sub-district like this.In one embodiment, each UNC can have single UMA sub-district, and in alternative embodiment, each access point that is connected with UNC can have a UMA sub-district.Because a large amount of AP are used in expectation, so the embodiment of back can not be to cater to the need especially, so the UMA structure allows AP is grouped into the UMA sub-district flexibly.Each UMA sub-district can be identified by sub-district global identifier (CGI), and wherein the absolute RF channel number of usefulness (ARFCN) is not assigned to each UMA sub-district.By the mode that each UMA sub-district is associated by the specific GSM band of position that MSC served together, each UMA sub-district can be mapped to the physical boundary.Mapping with the ARFCN to CGI of UMA sub-district is configured the GSM sub-district in the band of position that maps to the UMA sub-district.In addition, this ARFCN can by the GSM sub-district in BA tabulation advertisement to allow handover.Attention UMA can use identical location area identifier (LAI) as existing GSM sub-district in the sub-district, and perhaps new LAI can be used for the UMA sub-district.When the latter aspect knowing the paging that is reducing when travelling carriage is registered via INC in the GSM sub-district is of great use.Above-mentioned discussion can similarly be applied to GPRS Routing Area and Tracking Area Identifier symbol (RAI).
UMA CPE addressing
Customer premises equipment, CPE (CPE) can comprise travelling carriage and access point (AP), can insert the UNC of UMA service by the access point travelling carriage.UMA CPE addressing parameter can comprise parameter as described below.
UMA CPE addressing comprises that the international mobile subscriber identity (IMSI) related with the SIM in the mobile device is used as a parameter.When IMSI during to UNC request UMA service, provides IMSI to UNC by the UMA travelling carriage via upstream Interface.Be different from GSM BSC, the environment of each travelling carriage that the UNC management moves under the UMA pattern.Therefore, UNC safeguards the record of each travelling carriage of serving.For example, when UNC receives the BSSMAP beep-page message, IMSI can for UNC in order to search suitable travelling carriage record.
UMA CPE addressing comprise with mobile device in the address (for example, 802.11 MAC Address) of unauthorized interface conjunctionn be used as parameter.When UNC served via upstream Interface request UMA, identifier can be provided to UNC by the UMA travelling carriage.Thereby UNC can use this address to come substitute I MSI restricted passage upstream Interface to transmit IMSI and help the route of message.
UMA CPE addressing also comprises as a parameter supports node (SGSN) to distribute to the TLLI symbol (TLLI) of travelling carriage by service GPRS.This identifier can provide via standard Gb Interface program.UNC can follow the tracks of this address of each travelling carriage of serving to support GSM Gb Interface program (for example, so that the downlink gprs grouping can be routed to correct travelling carriage).
UMA CPE addressing also comprises the access point ID (AP-ID) as a parameter.AP-ID can be the MAC Address of non-licensing mode access point, and travelling carriage inserts the UMA service by this unauthorized pattern access point.When UNC served via upstream Interface request UMA, this identifier can be provided to UNC by the UMA travelling carriage.AP-ID can come user's location service enabled (for example, 911 of improvement services) from the AP of wherein access service with basis for the UNC use.AP-ID also can give the AP that authorizes so that the UMA service is inserted only restriction for service supplier's use.
Other CPE addressing parameters that can be used depend on the security requirement (for example, need perhaps need to manage the local certificate of being distributed to travelling carriage by UNC via the UMA travelling carriage IP address of the IPSec connection management message route of tunnel) of upstream Interface.
The UMA cell ID
In order to make the mobile management function facility among the GSM/GPRS, the overlay area can be divided into the logic registration zone that is called the band of position (for GSM) and Routing Area (for GPRS).When service position zone (perhaps Routing Area) changes, can require travelling carriage to register to network.One or more location area identifier (LAI) can be relevant with each location register of visiting (VLR) in the carrier network.Similarly, one or more Tracking Area Identifier symbols (RAIS) can be controlled by single SGSN.
In one embodiment, by cell identity (CI) being added into the mode in position or the Tracking Area Identifier, can be in position or Routing Area with the GSM cell ID.Cellular global identity (CGI) is the combination of location area and cell identity.In one embodiment, cell identity is unique in the band of position.
The example UMA method of cell ID
A case description of UMA cell ID means is as follows.In this embodiment, single UNC provides service for one or more UMA band of position and one or more UMA Routing Area, and each UMA band of position (perhaps Routing Area) is different or identical with the band of position (perhaps Routing Area) of overlapping GSM sub-district.Can in UMA position or Routing Area, identify the UMA sub-district by the mode that cell identity (CI) is added into position or Tracking Area Identifier.UMA cellular global identity symbol (UMA-CGI) is the combination of location area and cell identity.In one embodiment, the UMA sub-district can be the predefine part of the whole UMA overlay area that identified by the UMA-CGI value.Attention is as UMA information, and cell ID can be transparent for AP, so AP does not know the UMA-CGI value that it is related.UMA parts (for example, travelling carriage and UNC) can have the ability of supporting to divide whole UMA overlay area.
Division methods can be included in and realize man-to-man or many-to-one correspondence between GSM cell identity and the UMA cell identity.The sign of preferred GSM sub-district in the given specific region just can for example provide according to UNC and determine corresponding UMA cell identity.The example of one-one relationship is that the GSM sub-district maps to the UMA sub-district.The example of many-to-one relationship is that the GSM band of position (with the GSM sub-district that is associated) maps to the UMA sub-district.
When the UMA travelling carriage was connected to the UNC of UMA service, the UMA travelling carriage sent the path loss criterion parameter (C1) of CGI value and sub-district, (optionally) current GSM camp (camping cell) and adjacent cell to UNC.UNC is mapped to the CGI value of sub-district, GSM camp according to the mapping logic of stipulating the CGI value of corresponding UMA sub-district in UNC.This can be to shine upon (for example, if there is a UMA sub-district in each GSM sub-district) or many-one mapping (for example, if there is a UMA sub-district in each GSM band of position) one to one.If no GSM overlay area is available in the UMA coverage, UNC can distribute to travelling carriage " no GSM overlay area " UMA sub-district of acquiescence so.Single UNC can be a MSC service.This does not get rid of UNC embodiment, and combination is a plurality of as UNC defined above " example " in individual equipment (for example, the UNC that serves for a plurality of MSC) in described embodiment.Each UNC can also be assigned with to be used for unique " UMA-switching-CGI " value that GSM to UMA switches purpose.For example, this can be the value of stipulating to-CGI table and the MSC (for example, pointing to UNC) at the ARFCN-of GSM RAN BSC.
The UMA operative configuration
In one embodiment, can identify at least three UMA operative configuration.In general core configuration, UMA LAI and umbrella shape GSM RAN LAI are (for example, GSM RAN LAI for user's neighbours service) can be different, and can planned network so that identical core-network entities (for example, MSC and SGSN) can be UMA sub-district and the two service of umbrella shape GSM sub-district.An advantage of this configuration is that the user between UMA overlay area and GSM overlay area moves and can not produce in the system (for example, mapping) signaling (for example, position upgrade and switch be in the MSC).
In core configuration independently, UMA LAI is different with umbrella shape GSM RAN LAI, and so planned network so that different core-network entities is UMA sub-district and the service of umbrella shape GSM sub-district.An advantage of this configuration is that UMA and GSM Network Design can be independent of outside the general core configuration.
In general LAI configuration, UMA LAI and GSM RAN LAI are identical (for example, in identical LAI different sub-district).The advantage of this configuration is to move (when the free time time) may not can to produce any position and upgrade signaling the user between UMA overlay area and the GSM overlay area, if UMA mode resource unavailable temporarily (for example, in response to paging) then travelling carriage can easily forward the GSM pattern to.The more details of these and above-mentioned independently core configuration are to discuss to some extent in 10/688,470 the application at sequence number.
UMA registration and cancellation
In one embodiment, as mentioned above, the UMA registration process does not adopt signaling to give the mode of PLMN basic facilities and is comprised in (just, between travelling carriage and UNC) in the UMA system.The UMA registration process can be used for two purposes.It can be notified the UNC travelling carriage to be connected by specific AP and be available in the specific I P address.UNC can follow the tracks of this information, for example, and mobile termination.Registration process can also provide the operating parameter relevant with the UMA service on the AP to travelling carriage.This utilization that can be similar to GSM Broadcast Control Channel (BCCH) is with the travelling carriage of transfer system parameter to the GSM sub-district.Gsm system informational message content suitable in the UMA pattern can be delivered to travelling carriage during the UMA registration process.
Equally, UMA nullifies to handle and can allow travelling carriage clearly to notify UNC abandoning the UMA pattern about travelling carriage, thereby allows UNC to discharge the resource that may distribute to travelling carriage.UNC also can support the UMA that implies to nullify, and wherein the safe lane to travelling carriage is stopped suddenly.
The UMA changed course
In one embodiment, as mentioned above, when the UMA travelling carriage was connected to UNC with acquisition UMA service, UMA can send the CGI value and the path loss criterion parameter (C1) of sub-district, current GSM camp and adjacent cell to UNC.Utilize this information and internal data library information, perhaps UNC can determine whether it is the correct service UNC of travelling carriage, and if not correct service UNC, so travelling carriage is rerouted to correct UNC.Correct service UNC can be the equitant UNC in umbrella shape GSM overlay area of its UMA coverage and travelling carriage.In one embodiment, correct service UNC can be connected to umbrella shape GSM sub-district under the identical MSC of GSM BSC.In an alternative embodiment, correct service UNC can be connected to different MSC, and this MSC can switch to the MSC that offers travelling carriage umbrella shape GSM overlay area, thereby allows UNC to switch and switch to GSM from GSM.It can also start some location-based service (for example, E911 Phase1), and this service is subjected to pining down of GSM subdistrict position.The internal database that is used for UNC can be mapped to the GSM band of position service UNC, and preserves the amount of the data that need management.This database can be worked as when adding the new UNC or the new GSM band of position and changed.
If when travelling carriage is connected to UNC with acquisition UMA service, it is effective not having the GSM overlay area, UNC may not can determine reliably that the position of travelling carriage is to realize travelling carriage is assigned to the purpose (for example, starting switching and location-based service) of correct service UNC so in some instances.UNC can allow the operator to determine service strategy (for example, the operator can provide service to the user having under the situation of some restriction, and the user interface indication also can be provided) on travelling carriage in this case.To provide subsidiary details below about UMA registration and changed course process.
The action of UMA travelling carriage idle pulley
As mentioned above, UMA equipment can run into Fig. 4 illustrational different radio environment.In first environment, GSM and UMA overlay area are fully independently and disjoint.In second environment, overlap in the overlay area of GSM and UMA.In the 3rd environment, this environment may be the most general, and the UMA overlay area is comprised in the GSM overlay area.UMA equipment can be in these environment any in energized (power on), and can also conversion in a plurality of appended states.
When energized, and when travelling carriage be idle and during without any the overlay area of type, travelling carriage can be searched for the two radio coverage of GSM and UMA.If detect the GSM overlay area, can start normal GSM mobile management program so.When having detected no UMA overlay area, when detecting the GSM overlay area or before the UMA registration process is finished, can apply this condition by travelling carriage.If detect the UMA overlay area, the UMA travelling carriage is established to unauthorized Radio Link (for example, WLAN link) and the monitor signal quality of AP so.When the signal level that receives at the travelling carriage place surpassed predetermined threshold, travelling carriage was carried out the UMA registration process.Based on the information of returning, travelling carriage need can determine whether the whole network registration, and if like this, also needing to determine is what type (for example, the GSM/GPRS of GSM or combination).When having the GSM overlay area to exist or before detecting the GSM overlay area, detecting the UMA overlay area, can not use this process.
When travelling carriage in the GSM overlay area is idle, and when not having the UMA overlay area, travelling carriage can periodically be searched for the UMA overlay area so.If detect the UMA overlay area, travelling carriage can start aforesaid UMA enrollment process so.
Idle and when not having the GSM overlay area, travelling carriage can continue to carry out normal GSM PLMN search procedure so when travelling carriage in the UMA overlay area.If detect the GSM overlay area, travelling carriage can send the GSM cell information to reach aforesaid suitable UMA changed course purpose to UNC so.As selection, travelling carriage can forbid that normal GSMPLMN search procedure is to preserve electric weight.
When travelling carriage in the UMA overlay area is idle, and when having the GSM overlay area, travelling carriage can continue to carry out normal GSM sub-district and selects process and can store the sign of selected GSM sub-district so that accelerate to the conversion of GSM pattern if necessary more so.As selection, travelling carriage can forbid that normal GSM sub-district selects process to preserve electric weight again.
When breaking power supply (power off) in the UMA overlay area, send to separate (detach) by travelling carriage via UMAN and be indicated to PLMN (for example, if normally send by travelling carriage) by the PLMN network requirement or when the deenergization.Each current GSM operator scheme (for example, GSM or GPRS) this indication of can encoding.
The UMA environment can be IEEE 802.11 environment.In this case, travelling carriage is periodically carried out the efficient search that has to available 802.11 AP.When finding AP, being complementary of the profile (profile) that can select with the user who is stored and security certificates, and travelling carriage can automatically be associated with AP in such cases.Travelling carriage can enter the low power sleep mode, determines when that triggering UMA registers thereby periodically wake up with measures signal quality.
The UMA environment can be a bluetooth environment, and in this case, travelling carriage matches mutually with Bluetooth AP in advance, will insert the UMA service by the Bluetooth AP travelling carriage.Travelling carriage can periodically enter paging search receive mode, and sets up the link layer connection in response to AP transmits paging.In case the link layer control channel is established, and if travelling carriage be not in addition movable, travelling carriage may enter low-power bluetooth state (for example, PARK pattern) to preserve power so.AP periodically poll travelling carriage enters activity pattern (active mode) again to allow it.Thereby this cycle conversation also can be used for travelling carriage determines when execution UMA enrollment process with measures signal quality.
The action of UMA travelling carriage dedicated mode
The UMA equipment that is used for audio call, data transactions or simultaneous voice/data transactions may run into conversion or the conversion from the UMA overlay area to the GSM overlay area from the GSM overlay area to the UMA overlay area.In one embodiment, when the overlay area when GSM is transformed into the UMA overlay area, call out and between GSM RAN and UMAN, can switch pellucidly.Under the situation of voice, this switching can be finished by handoff functionality.Under data conditions, the user that conversation management control may provide in GPRS provides the general purpose terminal user experience.If suitably then when turning back to idle condition, just normal registration action may take place.When the overlay area when UMA is transformed into the GSM overlay area, calling can be switched between UMAN and GSM RAN pellucidly.Under the situation of voice, this switching can be finished by handoff functionality.Under data conditions, the user that conversation management control may provide in GPRS provides general end-user experience.
The summary of crucial mobile management notion
Fig. 5 for example understands the mobile management function in an example embodiment.In Fig. 5, unauthorized network controller UNC-1 is the service UNC of the UMA sub-district related with GSM band of position LA-11 to LA-23.UNC-1 is mapped to UMA sub-district UMA CGI-101 with GSM band of position LA-1x, and GSM band of position LA-2x is mapped to UMACGI-102.Unauthorized network controller UNC-3 is the service UNC of the UMA sub-district related with GSM band of position LA-31 to LA-33.UNC-3 is mapped to UMA sub-district UMA CGI-301 with GSM band of position LA-3x.Mobile station MS-1 will be arranged in UMA sub-district UMA-CGI-101 (because GSM LA-1x is mapped to UMA-CGI-101).Mobile station MS-2 will be arranged in UMA sub-district UMA-CGI-102 (because GSM LA-2x is mapped to UMA-CGI-102).Mobile station MS-3 will be arranged in UMA sub-district UMA-CGI-301 (because GSM LA-3x is mapped to UMA-CGI-301).If mobile station MS-4 is connected with UNC-1, it will be among the UMA-CGI-199 of UMA sub-district so (does not have the GSM overlay area).If mobile station MS-4 is connected with UNC-3, it will be arranged in UMA sub-district UMA-CGI-399 (not having the GSM overlay area) so.Mobile station MS-1 can be connected with UNC-1 under the situation that need not to alter course with MS-2.If mobile station MS-3 tries to be connected to UNC-1, it can be redirected to UNC-3 so.
Be used for the location-based service of emergency and other purposes
Be possible be used for selecting UNC to come from the calling of MS or mail to the method for the calling of MS below with processing.At first, UNC is from the MS receiving position information.Positional information can be taked any of several different forms.Near the sign of the cellular basestation in one embodiment, positional information comprises.For the example of the MS 102 of Fig. 7, positional information can comprise sign, such as BSID (Base Station Identification) or the BSCC (base station code (Base Station Color Code)) of several BTS 120.In the example of Fig. 7, these are the base stations within the scope of MS.Positional information can also comprise RxLEV (receiver stage) or the RSSI (signal strength indicator of reception) that is associated with the cellular basestation sign of each reception.
In GSM, " BSID " takes the form of cellular global identity (CGI).This can have such form, wherein can identify sub-district in BSS and the BSS by CI being added into mode in position or the Tracking Area Identifier in position or Routing Area.CI has the regular length of 2 eight bit bytes and it can utilize complete sexadecimal notation to encode.CGI is the combination of LAI and CI.LAI has three key elements, and the mobile station country code is identified at the mobile network code, MNC of this national GSM PLMN, and the location area codes that is identified at the band of position in the GSM PLMN.
As selection, positional information may not relate near the base station any, and relates to the AP that connected.MS may not be positioned within the scope of any base station so may not have any effective base station information and will send.Positional information can take connect the form of the latitude and longitude coordinates of the street address of sign, AP of AP or AP.These for example can obtain via the GEOPRIV of the expansion of DHCP.
UNC selects network controller according to this comparative result then.This selection can be by being applied to CGI mapping table or various other variety of way is finished.The address that these modes can comprise from one of above-mentioned tabulation or the mode of the best base station by selecting travelling carriage reads suitable AP, the mobile switching centre that is connected with selected base station of sign, and the switching network controller that is connected with the mobile switching centre that is identified of selection.If the position relates to wireless aps, so after the position of determining AP, can be by being designated mobile switching centre near the location-based service of determined connection WAP (wireless access point), and select the mode of the network controller that is connected with sign mobile switching centre to finish selection.Look the difference of application-specific and can finish selection in various other modes.
UNC sends the address of selected network controller to MS.This permission MS recording address and foundation are connected with UNC's.Selected UNC may be identical with selected UNC, and the UNC that perhaps makes one's options can be redirected to MS different UNC.In one embodiment, the UNC calling or the registration that also will exist is passed to the UNC that has selected.
Fig. 6 has shown the example of the signal sequence that can pass through between first and second UNC of the MS on the side and AP and opposite side.In the example of Fig. 6, the aspect of two communication systems shown in Figure 7 is shown the top of crossing over described figure.The signal that passes through between different aspect is shown as horizontal arrow, and wherein arrowhead connects the aspect of related communication system.When arrow crossed on the one hand and do not have the arrowhead demonstration, this aspect was the unique aspect that can pass through so.Arrow is by the letter sign of figure right-hand side.The particular aspects of the system configuration of related Fig. 1 is travelling carriage (for example MS102) from left to right successively among Fig. 6, access point (for example WLANAP128), a UNC (for example UNC140) and the 2nd UNC (for example UNC140).Signal shown in Figure 6 relates to signaling and does not indicate flow or payload.
Fig. 6 has shown the example of registering and be redirected to the MS of another UNC (UNC 2) to UNC (UNC140) between record time.Registration can be taked various form, comprises aforesaid those forms.Particularly, in the example of Fig. 6, MS is from UNC request service and positional information is provided.Be redirected to the 2nd UNC then.The 2nd UNC may be more suitable for the reported position in MS.
At the line A of Fig. 6, MS enters the covering area range of AP and sets up Radio Link with AP.This can be to utilize the WLAN of unauthorized frequency to connect.Online B, MS seek UNC to connect.This can finish the mode of DNS (domain name system) inquiry of UNC by execution.This starts the connection to a UNC IP address.MS can select a UNC, because the up-to-date UNC IP address that it is to use or may be the acquiescence UNC, perhaps may be the ownership UNC that MS is assigned with in initial registration, perhaps may be from by AP and CGI pointed be connected the high-speed cache of UNC and select.Online C, UNC have set up TCP with MS and have been connected.Note not being presented in the drawings the security processes between MS and the UNC.
Online D, MS send registration message to UNC.This registration message can take a number of different forms.In one embodiment, registration message can be imitated UMAURR-REGISTER-REQUEST message.Except that the normal registration content, this message can comprise the reason of connection, the identification number of AP and address and about the information of the transmission base station in the scope.
In gsm system, this information is marked as Cell-Info and comprises CGI and (optional) C1 value.In one embodiment, only report independent CGI, the GSM sub-district that expression MS has utilized its normal GSM cell selecting process to select by MS.This single subdistrict is selected with as " best " GSM sub-district by MS.Usually in order to derive this value, MS will search for some specified frequency to search broadcast channel (BCH) transmission.BCH transmits the base station with identification and comprises the access at random of relevant certain base station use and the information of Traffic Channel.MS can write down base station identity and measure this quality of signals when receiving the BCH signal.In gsm system, RXLEV (received signal level) is generally measured, but instead can use other mass measurements, the perhaps measurement except that RXLEV comprises signal to noise ratio, bit error rate (BER), RSSI (signal strength indicator of reception) and signal propagation delays.
Online E, the information of the relevant position that the UNC assessment is received is also selected the suitable UNC that is used for MS.As long as MS remains connected to identical AP and then can keep this selection.As mentioned above, exist various mode to select suitable UNC.In one embodiment, UNC is mapped to the corresponding UNC with the MSC of best base station with base station information.In another embodiment, UNC is mapped to the position with the sign of AP, is mapped to corresponding M SC, is mapped to corresponding UNC then.In another embodiment, UNC about the positional information of base station or AP, does not also select UNC but it has from the registration formerly of the AP that comprises positional information in view of the above.
In the example of Fig. 6, the MS 102 (as shown in Figure 7) of top can be connected with following UNC 140 at first.This UNC is connected with following MSC 110.Positional information from MS will identify the one or more top BTS 120 that are connected with top MSC 110.If MS roams into top BTS from top AP 128, call out so and can manage by following MSC by top MSC.By MS being rerouted to the UNC of top, can be by top MSC administer calls.This may produce the level and smooth conversion of travelling to and fro between top BTS and reduce to handle and call out required amount of network resources.
The address that online F, UNC confirm the registration request and send selected UNC is to MS.Form or any other form of FQDN (FQDN) can be adopted in the address.Line F approves the form that is similar to UMA URR-REGISTER-REDIRECT with employing really, and is perhaps various other forms of any.
Online G, MS carry out the DNS inquiry to selected UNC.It can also be discharged into the connection of a UNC and start to the connection of the 2nd UNC IP address.Therefore, online H sets up TCP and connects between MS and new UNC, and wherein MS is redirected to new UNC.Online H connects between MS and the 2nd UNC.Utilize the IPSec passage of original UNC can be repeated to use or can set up new IPSec passage (not shown).
Online I, MS can send similar register request message to the two UNC.This message can be similar to the message of line D.In the message of URR-REGISTER-REQUEST type, the reason field can be carried and is used to replace normal the connection and the value of changed course.Information in the registration request can make new UNC use the information of the essential MS of changed course in addition.Because it approaches the position of AP, so it may have more or better information about AP, near base station or Resource Allocation in Networks, and the MS that may alter course in addition.The reason field can be used for notifying the number of MS about changed course.Perhaps, it is used for being restricted at the sum of the changed course of single AP experience 1 or 2 or any other number.
Online J continued with being connected along its normal processes of UNC.This can comprise registration affirmation, call setup and disconnection, and any various support voice or the data, services that comprise safety measure.
Fig. 7 has shown the aspect of Fig. 7 identical with Fig. 6, crosses over the top and send signal in the same manner by the line that letter identified.But in Fig. 7, the MS register can not send any positional information.In case it has positional information, it just sends to the UNC that registers with this information so, and it is redirected to more suitable UNC then.Utilization is similar to processing shown in Figure 7, and MS can at any time upgrade its position.The message of Fig. 7 can be copied Fig. 6,8 or 9 stream.
Online A, MS have the registration of setting up with a UNC 140 and pass through AP 128 communications.Online B, MS obtain effectively or the positional information of upgrading.Perhaps, it can not receive base station BCH transmission, and perhaps perhaps it can't obtain the accurate information about AP, and perhaps these two kinds of situations have.Positional information among the line B can be new, that upgrade or more accurate positional information.
Online C, MS send its position to UNC.In one embodiment, this information adopts the form of URR-REGISTER-UPDATE-UPLINK message.Positional information can adopt above-mentioned any form, perhaps adopts other form.
Online D, the UNC using location information is to determine the optimum UNC for MS.This can be same or different with the UNC that has wherein registered MS.Any above-mentioned one or more means can be used to select UNC.Online E, MS is altered course, if suitably and to the UNC of changed course register.This can utilize URR-REGISTER-REDIRECT to order and realize.This processing can take to be similar to the form of the line g-j of Fig. 6.
Fig. 8 has shown the aspect identical with Fig. 7, crosses over the top and is sending signaling in the mode identical with Fig. 6 on by the line that letter was identified.In Fig. 8, MS can not provide any positional information between record time.Online A, MS 102 enter the covering area range of AP 128 and set up communication link by the unauthorized channel such as the WLAN channel.Online B, MS use this connection by AP to be established to the connection of UNC 140.The same in Fig. 6 and 7, this can be the UNC of acquiescence, to the last UNC of its registration, and the UNC that provides by AP, the perhaps UNC that selects in any other mode.Online C, MS set up TCP with UNC and are connected.
As among Fig. 6, after setting up the TCP connection, so online D, MS send its registration message that comprises positional information.Yet in the example of Fig. 8, MS can not receive any base station transmits, so the cell information field is empty.Perhaps, MS can send the information of relevant AP, for example identification number, MAC (medium access control) address or BD (bluetooth equipment) address.UNC can use the cell information field position of MS to be determined to the resolution of GSM sub-district.Yet, if this information is not that effectively UNC can search AP the MS position is determined to the resolution of AP in mapping or tracing table or database so.If the position of AP is to know accurate the sixth of the twelve Earthly Branches, the scope of AP will be more accurate than the scope of GSM sub-district so.Usually AP will have 10 or 100 meters scope, and the GSM sub-district will have 1000 meters scope.Yet the scope of various transmitting sets and receiver will depend on specific implementation.
If MS does not provide the information of relevant neighbor base station (cell information is for empty) and AP is not had available positional information, UNC can not determine the position of MS reliably so.This may have influence on the ability that UNC selects the base station, and it also may have influence on the service that relies on positional information, comprises emergency (E911) service.Online E, UNC confirms that by returning registration the mode of (URR-REGISTER-ACK) is notified to MS with this, (LCS) is unavailable in the indicating positions service.
Online F continues described connection procedure in the mode of the line j that is similar to Fig. 6.According to network configuration, operator or service supplier can select not provide service to the user who does not have any positional information.In this case, UNC can replace refusal of registration attempt.Alternatively, UNC can alter course MS to such UNC, and this UNC is configured to the user's service with positional information.For example, this UNC can be configured to refuse any emergency services or provide emergency services to hold the mode that lacks positional information.
Fig. 9 has shown the aspect identical with Fig. 7, crosses over the top and to send signal with the same way as of Fig. 6 on by the line that letter was identified.In Fig. 9, MS does not upgrade positional information after the registration under having the situation of positional information.The message of Fig. 9 can be copied Fig. 6, those message of 7 or 8.
The AP128 of the normal connection that online A, MS102 set up by having is connected with UNC140.Online B, MS user see that location-based service is not available and imports the positional information of the AP that MS connects.This can be street address, postal service or ZIP coding, longitude and latitude or any other information.Online C, MS accept this information and it are formatted as registration updating message (URR-REGISTER-UPDATE-UPLINK).UNC receives this information and upgrades its MS record.
Online D, if UNC determines enough accurate position from the registration updating message, UNC transmission message (URR-REGISTER-UPDATE-DOWNLINK) is available with the indicating positions service now so.Therefore, online E, MS can send a signal to the user by the user interface of for example screen display and so on, shows that location-based service is available.
Fig. 7 and 9 message also can be used when an AP moves to another AP the user.These message can be used for reporting the positional information of new AP.These message also can be used for reporting the base station information that obtains recently.The broadcast channel of base station may be blocked by physical obstacle or multipath interference.MS can rescan BCH transmission occasionally, and if its receive different information, then send registration and upgrade.UNC can use the state of this information with the renewal location-based service, thereby estimates whether MS should be redirected to different UNC and be used for other processing.UNC can also use the identity of new AP and positional information to determine whether denial of service.Some position or AP can be positioned at outside network or the scheduled plan (subscription plan), so that should be rejected from the service of such AP.
