Definitions
- GSM Global System for Mobile Communication
- a large number of telecommunication services are already offered to customers of telecommunication networks, in particular mobile radio networks.
- the concept of the intelligent network has been developed in order to offer new services quickly and as independently of the manufacturer and network operator as possible, taking into account the existing infrastructure.
- a standardized concept was developed within the ITU (see standards Q.1200 ff), which defines the IN architecture.
- C7AMEL Customerized Application for Mobile Network Enhanced Logic, see also GSM 02.78
- IN features were introduced into the GSM architecture.
- C7AMEL is the "roaming" international nal and between different operator networks simplified and a uniform protocol created for access to CAMEL servers in external GSM networks ..
- the object of the invention is to provide a solution to the above problem with international or inter-provider
- Another object of the invention is to implement a callback service in a mobile radio network.
- the call back service according to the invention for roaming mobile radio subscribers allows PLMN operators to take advantage of a call back service.
- the callback service ⁇ "USSD Call Back Service”) UCB provides the desired functionality:
- the IN service UCB is triggered by means of the "USSD string" from the visited network VPLMN. If the roaming subscriber is not an IN customer, the HLR forwards the USSD string to a standard SCP that supports UCB; if he is an IN customer, this is correct SCP address in the "CAMEL Subscriber Information" CSI. With a callback service, the fee ratio can be reversed in favor of the HPLMN operator of the home network: Since the call is set up by the HPLMN, the HPLMN operator now receives the larger proportion of the fees.
- UCB enables roaming subscribers to make calls via IN, even if the visited network (VPLMN) uses the CAMEL protocol
- the service UCB is therefore available to roaming IN customers who can use their subscribed service even without CAMEL, ie roaming participants use CAMEL in VPLMNs that support CAMEL, in countries without CAMEL support the USSD solution is used.
- Non-IN customers can also use UCB.
- the IN service UCB solves this problem by cleverly setting the "Called Party Address” CdPA and "Calling Party Address” CgPA.
- FIG. 1 shows the activation of the UCB service in the SCP
- FIG. 2 shows the establishment of the “call back” connection according to the invention
- Figure 3 shows the interworking with a telecommunications network that does not support CAMEL.
- FIG. 1 shows how the callback service UCB is triggered by an incoming USSD (Unstructured Supplementary Service Data) string that the roaming mobile subscriber sends via the mobile switching center MSC in the visited network VPLMN, A.
- USSD Unstructured Supplementary Service Data
- a "USSD string” is intended for the home register HLR in which the subscriber is administered.
- the "Follow-Me” functionality available in Siemens HLRs is used here based on the USSD string control information (header).
- SR7 Mobile Subscriber ISDN Number
- a party forwards it to a service center SCP that supports the callback service UCB (B).
- the SCP starts the IN service UCB. This in turn sends the A party a USSD string that confirms the input, C, D.
- the IN service UCB first establishes a connection to the A party using "InitiateCallAt tempt" ICA, see FIG. 2.
- Calling Party CgPA is now the actually selected Called Party CdPA (B party) and CdPA is the original CgPA (MSISDN the A-Party); at the same time all "Event Detection on Points” EDP are armed with "RequestReportBCSMEvent” RRB, 21, and then continue with "Continue” CUE.
- a gateway mobile switching center GMSC interrogates the subscriber register HLR of the subscriber GSM as standard with the "send routing information" SRI, 22, 23.
- the connection to the roaming A party is established via an IAM, 24.
- the "UBC service” receives the information via "EventReportBCSM” ERB, whether the A-party answered (answer), is busy (busy), does not answer ⁇ no_answer) or cannot be reached ⁇ not_reachable), 25.
- the billing is guaranteed for the scenario: the GMSC creates a "roaming ticket" with "answer” from A, in which the answer time is entered. An "MTC Ticket” is written in the A-Party's VMSC, and the SSP writes an "IN AMA Ticket” due to the FCI operation.
- UCB uses "GetUserRecord" to distinguish whether and which IN service the A party has subscribed to. If the A party has no IN subscription, UCB proceeds as described above.
- UCB extends the CgPA in the "Initia teCallAt tempt" ICA by an administrable number of administrable digits XXX, which can also contain hexadecimal digits (the subscribed IN service is shown in FIG. 3 as an example) : Prepaid Service), 1.
- the subsequent interrogation of the HLR, 2 and 3, may provide a T-CSI.
- UCB continues with the operation "Connect" CON, which contains the MSISDN of the A party as the calling party CgPA and as the called party CdPA the originally dialed number of the B party, extended by an administrable number of administrable digits YYY (hexadecimal digits possible), 11.
- YYY a code point must be set up on the SSP, which uses an IDP (Initial Detection Point), 12 to provide the desired IN service on 'correct' SCP triggers (YYY must therefore be set up specifically for IN Service).
- the service logic EntryFSL or the MOC IN service logic must determine the A-location via the "AnyTime Interrogation" ATI, 13.
- the MOC service logic then runs, as if it had been started directly via a CAP: IDP. In the case shown, PPS continues with "ApplyCharging” AC and "Connect” CON B-Party.
- GSM 02.78 GSM Logic
