Description
Technical field
The present invention relates to mobile communication technology, particularly the method that storage configuration identification heavily distributes in the mobile communication system.
Background technology
In recent years, fast development had taken place in the global mobile communication technology, and 3G (Third Generation) Moblie (3rdGeneration is called for short " 3G ") is the inexorable trend of development.(the InternationalTelecommunication Union of International Telecommunications Union, be called for short " ITU ") stipulated five kinds of land wireless technologys at 3G, Wideband Code Division Multiple Access (WCDMA) (Wideband Code Division Multiple Access wherein, abbreviation " WCDMA "), CDMA 2000 (Code Division Multiple Access 2000, be called for short " CDMA2000 ") and TD SDMA (Time Division Synchronous CodeDivision Multiple Access, abbreviation " TD-SCDMA ") be three kinds of mainstream technologys.
The WCDMA standard is worked out by third generation partner program (3rd Generation PartnershipProject is called for short " 3GPP "), four versions has been arranged at present, i.e. R99, R4, R5 and R6.Its main feature is land radio access web (Universal Terrestrial Radio AccessNetwork, be called for short " UTRAN ") employing WCDMA technology, core net (Core Network, abbreviation " CN ") is divided into circuit domain and packet domain, support voice service and data service respectively, the Iu interface is the interface between UTRAN and the CN.Wireless network layer signaling on the Iu interface is by wireless access network applying portion (Radio Access Network Application Part, be called for short " RANAP ") transmit, RANAP is responsible for handling all basic processes between UTRAN and the CN, and the combination of these basic processes can realize diversified RANAP function.
There has been company to propose UTRAN at present and issued configuration parameter in advance, and be stored among the UE, when call setup, directly used the stored configuration scheme of stored configuration item.Thus,
Avoided making relevant signaling volume excessive, caused the bigger phenomenon of the time delay that continues when the configuration parameter that transmits a greater number by wave point.
Below the stored configuration item is described further.
Article one, the stored configuration item comprises RB configuration parameter, transmission channel configuration parameter and physical channel configuration parameter, and this stored configuration item is by a unique storage configuration identification (Stored ConfigurationIdentity is called for short " SCI ") expression.
When using 1 configuration item for the first time, UTRAN is by DPCH, and " RB Setup (radio bearer the foundation) " message that will include the entire arrangement parameter sends to UE, in addition, also comprises the SCI of this configuration item correspondence in this message.After UE receives this message, store this configuration item and corresponding SCI.After this, when needs used this configuration item, UTRAN no longer sent concrete configuration parameter to UE, only need specify the pairing SCI of configuration item that will use to UE.
UTRAN is by BCCH broadcasting current effective SCI, and UE checks the configuration item of having stored according to broadcasting, if the SCI of the configuration item of storing itself is not included among the current effective SCI of broadcasting, then the configuration item of correspondence is deleted.It is pointed out that in addition if UE is not owing to receiving broadcast message such as reasons such as shifting out service area, after then will expiring, the configuration item deletion of correspondence at 6 hours timer.
In order to save the bandwidth of BCCH, the method by broadcasting SCI valid interval makes the invalid stored configuration item of UE deletion at present.Specifically, the minimum SCI and the maximum SCI of UTRAN broadcasting SCI valid interval.SCI in the interval that these two SCI define all is considered as effectively, and it is invalid that the SCI outside the interval all is considered as, with the stored configuration entry deletion of invalid SCI correspondence.For this reason, UTRAN must manage the SCI of all configuration items, makes them become a continuous interval.
Next introduce the process of UTRAN change stored configuration item.
As shown in Figure 1, wherein A, B, C and D represent 4 stored configuration items.At first, UTRAN supports above-mentioned 4 configuration items, and effective SCI interval of broadcasting is (0,3), and promptly all SCI in (0,3) are all effective.Then, UTRAN revises configuration item B, produces new configuration item B ', and the SCI of B ' correspondence is " 4 ".As mentioned above, in order to guarantee the continuous of effective SCI interval, UTRAN can not delete original configuration item B, and effective SCI interval of broadcasting is (0,4).In this case, if UE has used configuration item B ', then can store B and B ' simultaneously.Then, in order to reclaim the SCI that configuration item B is occupied, and guarantee that effective SCI is interval and connect that UTRAN heavily distributes a SCI for configuration item A, new SCI is " 5 ".
It is pointed out that in the process of above-mentioned modification configuration item,, just can obtain the heavy assignment information of SCI of configuration item A when UE carries out RB when setting up process.
Specifically, in order to reclaim the shared SCI of configuration item B, and guarantee that effective SCI is continuously interval, as mentioned above, UTRAN heavily distributes a SCI " 5 " for configuration item A.This moment, UTRAN can comprise old SCI and the new SCI of configuration item A in " RB Setup " message if UE has carried out RB and set up process, and notice UE side is also heavily distributed the SCI of configuration item A.It is pointed out that it must be configuration item A that the configuration item that uses in the process that this RB sets up does not need, also can be other configuration item.Process is referring to Fig. 2.In order to guarantee that abundant UE obtains the heavy assignment information of SCI of configuration item A, UTRAN can keep SCI " 0 " and " 1 " effectively in a period of time, and this moment, the SCI valid interval of broadcasting was (0,5).
After after a while, it is (2,5) that UTRAN changes the SCI valid interval.The UE that receives valid interval is the configuration item B deletion of storage, and the UE that does not receive valid interval owing to reason such as beyond service area also can delete configuration item B to after date at 6 hours timer; The UE that does not before obtain the heavy assignment information of SCI of configuration item A can when by the time using A, need UTRAN to issue configuration item A again configuration item A deletion this moment next time.
In actual applications, there is following problem in such scheme: only carry out RB when setting up process as UE, just can obtain heavy assignment information, and can only obtain the heavy assignment information of SCI of a configuration item.The UE that fails in time to obtain this information can be with this configuration item deletion when UTRAN reclaims old SCI, and again need UTRAN again to issue when using next time.Especially the configuration item that need heavily distribute SCI in the UTRAN side more for a long time to set up the number of times of process less because UE can carry out RB in a period of time, can cause UE that a large amount of configuration items of having stored is carried out unnecessary deletion, referring to Fig. 3.
Summary of the invention
In view of this, main purpose of the present invention is the method that storage configuration identification heavily distributes in a kind of mobile communication system is provided, and makes UE because of obtaining the heavy assignment information of SCI the chance that the configuration item of partly storing carries out unnecessary deletion can effectively not reduced.
For achieving the above object, the invention provides the method that storage configuration identification heavily distributes in a kind of mobile communication system, comprise following steps:
The network side of described system is issued to subscriber equipment in the involved area with heavy assignment information after the storage configuration identification to the stored configuration item heavily distributes;
Described subscriber equipment calculates at least one according to described heavy assignment information and heavily distributes interval and corresponding side-play amount thereof, and heavily distributes interval interior storage configuration identification to upgrade by the interval corresponding side-play amount of this heavy distribution to dropping on of storing in this subscriber equipment.
Wherein, described heavy assignment information comprises at least one tlv triple, and this tlv triple comprises following parameter:
Represent the interval original position of described heavy distribution first parameter,
Represent the interval end position of described heavy distribution second parameter and
The 3rd parameter of representing the interval corresponding side-play amount of described heavy distribution.
In this external described method, when described subscriber equipment upgrades storage configuration identification,, handle according to the following steps for each described tlv triple:
Each bar configuration item for the current storage of described subscriber equipment, whether the storage configuration identification of judging this configuration item respectively is more than or equal to the value of described first parameter and smaller or equal to the value of described second parameter, if then the storage configuration identification with this configuration item adds the value of the above the 3rd parameter as the new storage configuration identification of this configuration item.
In this external described method, described heavy assignment information comprises at least one two tuple, and this two tuple comprises following parameter:
Represent the interval original position of described heavy distribution the 4th parameter,
The Wucan number of representing the interval end position of described heavy distribution.
In this external described method, when described subscriber equipment upgrades storage configuration identification,, handle according to the following steps for each described two tuple:
The upper limit of storage configuration identification valid interval in the described subscriber equipment is deducted described Wucan number, obtain side-play amount;
Each bar configuration item for the current storage of described subscriber equipment, whether the storage configuration identification of judging this configuration item respectively is more than or equal to the value of described the 4th parameter and smaller or equal to the value of described Wucan number, if then the storage configuration identification with this configuration item adds the above side-play amount as the new storage configuration identification of this configuration item.
In this external described method, described heavy assignment information comprises a storage configuration identification tabulation, represents the storage configuration identification of the configuration item that all need be deleted.
In this external described method, when described subscriber equipment upgrades storage configuration identification,, handle according to the following steps for described tabulation:
Calculate heavily distribution interval according to storage configuration identification in the described tabulation and valid interval;
The upper limit of described valid interval is deducted described heavy side-play amount of distributing the interval upper limit to obtain this heavy distribution interval;
For each bar configuration item of the current storage of described subscriber equipment, if drop in the described heavy distribution interval, then the storage configuration identification with this configuration item adds that this heavy side-play amount in interval of distributing is as the new storage configuration identification of this configuration item.
In this external described method, one of in the following manner or its combination, described heavy assignment information set is issued to subscriber equipment in the sub-district:
By Broadcast Control Channel all subscriber equipment broadcasting in the sub-district,
By Dedicated Control Channel, incidentally in downlink signaling, send to that all are in the subscriber equipment of point-to-point communication state in the sub-district.
In this external described method, after described heavy having assigned, in predefined duration, gather, and in this duration, gather by Dedicated Control Channel incidentally heavy assignment information in downlink signaling by the described heavy assignment information of Broadcast Control Channel all subscriber equipment repeated broadcast in the sub-district.
In this external described method, described mobile communication system is a broadband CDMA system.
Can find that by comparing the main distinction of technical scheme of the present invention and prior art is that the present invention issues at every turn and reshuffles all related heavy assignment information, and prior art issues in the wall scroll mode.The heavy assignment information that issues can be to represent heavily to distribute that the tlv triple of interval and side-play amount thereof, expression heavily distribute interval two tuples (default moving to after the valid interval) or represent the tabulation of deleted SCI.UE calculates according to heavy assignment information and heavily distributes interval and side-play amount thereof, and the SCI that in view of the above this UE is stored upgrades again.
The present invention after reshuffling immediately by Broadcast Control Channel and/or Dedicated Control Channel, with incidentally or direct mode issue the heavy assignment information of whole SCI.And in the prior art, only set up at RB and just obtain the heavy assignment information of SCI in the process, and UE can only obtain the heavy assignment information of SCI of a configuration item at every turn.
Difference on this technical scheme, brought comparatively significantly beneficial effect, promptly because issue heavy assignment information in the mode (can directly or indirectly calculate the interval) in interval in fact, so issuing the efficient of the heavy assignment information of SCI improves greatly, significantly reduce aloft the interface chance of transmission configuration item again, reduced the flow of air interface on the whole.
Because heavily divide timing in several ways the heavy assignment information of all SCI to be sent to UE at generation SCI, make the UE SCI of relevant configuration item that before UTRAN changes the SCI valid interval, can upgrade in time, thus the situation that can effectively avoid UE unnecessarily to delete because of the configuration item that obtains the heavy assignment information of SCI and will partly store.

Embodiment
For making the purpose, technical solutions and advantages of the present invention clearer, the present invention is described in further detail below in conjunction with accompanying drawing.
Core of the present invention is, when the UTRAN of network side need reshuffle configuration item, the heavy assignment information of all involved SCI is passed through Broadcast Control Channel and/or Dedicated Control Channel, with incidentally or direct mode all be handed down to UE, UE calculates according to heavy assignment information and heavily distributes interval and side-play amount thereof, and the SCI that in view of the above this UE is stored upgrades again.Wherein, described heavy assignment information can be to represent heavily to distribute that the tlv triple of interval and side-play amount thereof, expression heavily distribute interval two tuples (default moving to after the valid interval) or represent the tabulation of deleted SCI.
Because in the present invention, UTRAN issues all because of reshuffling the heavy assignment information that relates at every turn, has therefore significantly reduced UE because of not obtaining the situation that the heavy assignment information of SCI is carried out unnecessary deletion with the configuration item of partly storing.
The method that SCI heavily distributes in the mobile communication system of first embodiment of the invention as shown in Figure 4.
In step 410, when Radio Resource control was set up, the UTRAN of network side sent the valid interval of SCI to UE.
In step 420, when end was set up in Radio Resource control, UE returned the SCI tabulation of storage to UTRAN.
In step 430, the UTRAN of network side is after reshuffling certain configuration item, need involved SCI is heavily distributed, and the valid interval that will weigh assignment information and SCI is incidentally in downlink signaling, such as when radio bearer is set up, send to by Dedicated Control Channel that all are in the UE of point-to-point communication state in the sub-district.Wherein, described heavy assignment information comprises at least one tlv triple, and this tlv triple comprises following parameter: expression heavily distributes first parameter of interval original position, second parameter that expression heavily distributes interval end position and the 3rd parameter of representing heavily to distribute interval corresponding side-play amount.For instance, as shown in Figure 3, UTRAN is that 8 configuration item SC8 changes to SCI, with it as a new configuration item SC8 ', and for the SCI of its distribution be 10.So, in order to guarantee the continuity in SCI interval, it is 0 to SCI to be that 7 configuration item heavily is dispensed to the interval of SCI11 to SCI18 that UTRAN then needs SCI.Therefore, first parameter of heavily distributing interval original position in the heavy assignment information is 0, second parameter of heavily distributing interval end position is 7, and the 3rd parameter of heavily distributing interval corresponding side-play amount is 11 (SCI is that the SCI after 0 configuration item heavily distributes is 11, so side-play amount is 11).That is to say that the tlv triple in the heavy assignment information is (0,7,11), and UTRAN incidentally in downlink signaling, sends to that all are in the UE of point-to-point communication state in the sub-district with this tlv triple by Dedicated Control Channel.Certainly, if exist a plurality of heavy distribution interval, so, heavy assignment information can be represented with a plurality of tlv triple, equally by UTRAN should heavy assignment information incidentally in downlink signaling, send to by Dedicated Control Channel that all are in the UE of point-to-point communication state in the sub-district.
In step 440, UE upgrades by the interval corresponding side-play amount of this heavy distribution the interval interior SCI of heavily distribution that drops on that stores among this UE according to the heavy assignment information that receives, and the SCI of the storage after UTRAN returns renewal tabulation.Specifically, the SCI that UE judges this configuration item to each bar configuration item of current storage respectively whether more than or equal to the expression in the tlv triple heavily distribute interval original position first parameter value and heavily distribute the value of second parameter of interval end position smaller or equal to the expression in the tlv triple, if the value of the 3rd parameter that then SCI of this configuration item is added the corresponding side-play amount of expression in the tlv triple is as the new SCI of this configuration item.At above-mentioned case, UE receives tlv triple (0,7,11) after, can know and heavily distribute interval be (0,7), side-play amount is 11, and this UE upgrades by the interval corresponding side-play amount 11 of this heavy distribution the SCI that drops in the heavily distribution interval (0,7) that stores among this UE more then.If contain the configuration item of SCI1, SCI3, SCI5 and SCI6 at this UE internal memory, so, this UE upgrades its SCI to the configuration item of SCI1, SCI3, SCI5 and SCI6 by corresponding side-play amount respectively, that is to say, UE adds 11 with the original SCI of these four configuration items respectively, SCI after obtaining upgrading is respectively: SCI12, SCI14, SCI16 and SCI17.
In the present embodiment, UTRAN comes down to issue heavy assignment information in the mode in interval, improve greatly so issue the efficient of the heavy assignment information of SCI, significantly reduced aloft the interface chance of transmission configuration item again, reduced the flow of air interface on the whole.In addition, because UTRAN passes through Dedicated Control Channel, can in any downlink signaling, incidentally weigh assignment information, therefore, can make the UE SCI of relevant configuration item that before UTRAN changes the SCI valid interval, can upgrade in time, thus the situation that can effectively avoid UE unnecessarily to delete because of the configuration item that obtains the heavy assignment information of SCI and will partly store.
The method that SCI heavily distributes in the mobile communication system of second embodiment of the invention as shown in Figure 5.
Step 510 is identical with step 410.
Step 520 is identical with step 420.
In step 530, the UTRAN of network side is after reshuffling certain configuration item, need involved SCI is heavily distributed, and will contain expression and heavily distribute the valid interval of the heavy assignment information of two interval tuple R and SCI incidentally in downlink signaling, such as when radio bearer is set up, send to by Dedicated Control Channel that all are in the UE of point-to-point communication state in the sub-district.Wherein, described heavy assignment information comprises at least one two tuple R, and this two tuple comprises following parameter: represent the 4th parameter of the interval original position of described heavy distribution, the Wucan number of the interval end position of the described heavy distribution of expression.For instance, as shown in Figure 3, UTRAN is that 8 configuration item SC8 changes to SCI, with it as a new configuration item SC8 ', and for the SCI of its distribution be 10.So, in order to guarantee the continuity in SCI interval, it is 0 to SCI to be that 7 configuration item heavily is dispensed to the interval of SCI11 to SCI18 that UTRAN then needs SCI, and the valid interval of SCI becomes (0,18).Therefore, the 4th parameter of heavily distributing interval original position in the heavy assignment information is 0, and heavily distributing the Wucan number of interval end position is 7.That is to say that two tuples in the heavy assignment information are (0,7), so UTRAN incidentally in downlink signaling, sends to that all are in the UE of point-to-point communication state in the sub-district with two tuples (0,7) and valid interval (0,18) by Dedicated Control Channel.Certainly, if exist a plurality of heavy distribution interval, then heavy assignment information can represent that a plurality of heavy distribution are interval with a plurality of two tuple R, is R as heavy assignment information
1(S
1, E
1), R
2(S
2, E
2) ..., R
n(S
n, E
n), wherein, S represents heavily to distribute interval original position, and E represents heavily to distribute interval end position.R presses S sequence arrangement from small to large.Similarly, by UTRAN should heavy assignment information and valid interval incidentally in downlink signaling, send to by Dedicated Control Channel that all are in the UE of point-to-point communication state in the sub-district.
In step 540, UE upgrades by the interval corresponding side-play amount of this heavy distribution the interval interior SCI of heavily distribution that drops on that stores among this UE according to the heavy assignment information and the valid interval that receive, and the SCI of the storage after UTRAN returns renewal tabulation.Specifically, if UE receives the valid interval of one two tuple and SCI, so, this UE deducts the Wucan number that expression heavily distributes interval end position with the upper limit of valid interval, obtains side-play amount; If UE receives a plurality of two tuple R
1(S
1, E
1), R
2(S
2, E
2) ..., R
n(S
n, E
n) and the valid interval V of SCI (S, E), so, each heavily distributes interval side-play amount to be: Offset
i=E-E
n+ n-i i=1,2 ..., n
After obtaining side-play amount, whether the SCI that UE judges this configuration item to each bar configuration item of current storage respectively heavily distributes the value of the 4th parameter of interval original position and the value of heavily distributing the Wucan number of interval end position smaller or equal to expression more than or equal to expression, if then the SCI with this configuration item adds that the side-play amount that obtains is as the new SCI of this configuration item.
At above-mentioned case, UE receives two tuples (0,7) and valid interval (0,18) after, can know that heavily distributing the side-play amount of interval (0,7) is 11, this UE upgrades by the interval corresponding side-play amount 11 of this heavy distribution the SCI that drops in the heavily distribution interval (0,7) that stores among this UE more then.If contain the configuration item of SCI1, SCI3, SCI5 and SCI6 at this UE internal memory, so, this UE upgrades its SCI to the configuration item of SCI1, SCI3, SCI5 and SCI6 by corresponding side-play amount respectively, that is to say, UE adds 11 with the original SCI of these four configuration items respectively, SCI after obtaining upgrading is respectively: SCI12, SCI14, SCI16 and SCI17.
This shows, the present embodiment and first embodiment are basic identical, difference only is the method for expressing difference of heavy assignment information, in first embodiment, heavy assignment information is to represent by tlv triple, and in the present embodiment, heavy assignment information is to represent by two tuples, therefore, present embodiment can reach effect and the effect of first embodiment fully.
The method that SCI heavily distributes in the mobile communication system of third embodiment of the invention as shown in Figure 6.
Step 610 is identical with step 410.
Step 620 is identical with step 420.
In step 630, the UTRAN of network side is after reshuffling certain configuration item, need involved SCI is heavily distributed, and the valid interval that will contain the heavy assignment information of a deleted SCI tabulation D and SCI is incidentally in downlink signaling, as when radio bearer is set up, send to by Dedicated Control Channel that all are in the UE of point-to-point communication state in the sub-district.Wherein, the SCI that heavy assignment information comprises tabulates, and represents the SCI of the configuration item that all need be deleted.For instance, as shown in Figure 3, UTRAN is that 8 configuration item SC8 changes to SCI, with it as a new configuration item SC8 ', and for the SCI of its distribution be 10.So, in order to guarantee the continuity in SCI interval, it is 0 to SCI to be that 7 configuration item heavily is dispensed to the interval of SCI11 to SCI18 that UTRAN then needs SCI, and the valid interval of SCI becomes (0,18).Therefore, UTRAN tabulates D (8) and valid interval (0,18) incidentally in downlink signaling with SCI, sends to by Dedicated Control Channel that all are in the UE of point-to-point communication state in the sub-district.Certainly, more than one of the configuration item of deletion possibility, if need be deleted by multinomial configuration item, so, the SCI tabulation in the heavy assignment information is D (D
1, D
2..., D
n), the SCI in the tabulation is by from small to large sequence arrangement, similarly, by UTRAN should the weight assignment information and valid interval incidentally in downlink signaling, send to by Dedicated Control Channel that all are in the UE of point-to-point communication state in the sub-district.
In step 640, UE upgrades by the interval corresponding side-play amount of this heavy distribution the interval interior SCI of heavily distribution that drops on that stores among this UE according to the heavy assignment information and the valid interval that receive, and the SCI of the storage after UTRAN returns renewal tabulation.Specifically, UE calculates heavily distribution interval according to SCI tabulation that receives and valid interval, the upper limit with valid interval deducts the side-play amount that the upper limit of heavily distributing the interval that calculates obtains this heavy distribution interval again, at last, respectively each bar configuration item of current storage being judged whether the SCI of this configuration item drops on heavily distributes in the interval, if then the SCI with this configuration item adds that the side-play amount that obtains is as the new SCI of this configuration item.At above-mentioned case, the SCI tabulation D that UE receives is (8), valid interval (0,18).Because heavily distributing the interval is that first SCI is to the SCI-1 of deleted configuration item in the valid interval, therefore, heavily distributing the interval is (0,7).The upper limit 18 with valid interval deducts the side-play amount 11 that the upper limit 7 of heavily distributing the interval that calculates obtains this heavy distribution interval again.At last, UE upgrades by the interval corresponding side-play amount 11 of this heavy distribution the SCI that drops in the heavily distribution interval (0,7) that stores among this UE again.If contain the configuration item of SCI1, SCI3, SCI5 and SCI6 at this UE internal memory, so, this UE upgrades its SCI to the configuration item of SCI1, SCI3, SCI5 and SCI6 by corresponding side-play amount respectively, that is to say, UE adds 11 with the original SCI of these four configuration items respectively, SCI after obtaining upgrading is respectively: SCI12, SCI14, SCI16 and SCI17.
If in this step, the SCI tabulation that receives of UE is D (D
1, D
2..., D
n), valid interval is that (S, in the time of E), then heavily distribute the interval is { R to V
i(S
i, E
i) | S
i≤ E
i, 1≤i≤n}, wherein S
i, E
iComputational methods be:
E
i＝D
i-1?1≤i≤n
Certainly, if S
iGreater than E
iThe time, this heavy allocation space then needs deleted.After obtaining heavy allocation space, calculate each more as stated above and heavily distribute interval side-play amount and new SCI.
This shows, the present embodiment and first embodiment are basic identical, difference only is the method for expressing difference of heavy assignment information, in first embodiment, heavy assignment information is to represent by tlv triple, and in the present embodiment, heavy assignment information is to represent by the tabulation of the SCI of all configuration items that need delete, therefore, present embodiment can reach effect and the effect of first embodiment fully.
The method that SCI heavily distributes in the mobile communication system of fourth embodiment of the invention as shown in Figure 7.
In step 710, UTRAN is by the valid interval of all the UE broadcasting SCIs of Broadcast Control Channel in the sub-district.With Fig. 3 is example, and UTRAN is by the valid interval (0,9) of all the UE broadcasting SCIs of Broadcast Control Channel in the sub-district.
In step 720, when UTRAN has carried out change to certain configuration item after, the valid interval of broadcasting amended SCI by Broadcast Control Channel all UE in the sub-district.At above-mentioned case, UTRAN is that 8 configuration item SC8 changes to SCI, with it as a new configuration item SC8 ', and for the SCI of its distribution be 10, so, UTRAN broadcasts the valid interval (0,10) of amended SCI by Broadcast Control Channel all UE in the sub-district
In step 730, the UTRAN of network side needs heavily to distribute involved SCI after reshuffling certain configuration item, and the valid interval that will weigh assignment information and SCI is by Broadcast Control Channel all UE broadcasting in the sub-district.Need to prove, after heavily having assigned, UTRAN can be by the described heavy assignment information set of Broadcast Control Channel all UE repeated broadcast in the sub-district in predefined duration, to guarantee that most UE can obtain heavy assignment information, and in this duration, gather by Dedicated Control Channel incidentally heavy assignment information in downlink signaling, should heavy assignment information send to UE.Wherein, the heavy assignment information in the described heavy assignment information and the first embodiment of the present invention is identical, does not repeat them here.At above-mentioned case, the heavy assignment information of UTRAN broadcasting is (0,7,11), and the valid interval of SCI is (0,18).
After UE obtained heavy assignment information set by Broadcast Control Channel or by Dedicated Control Channel, the method described in 440 was upgraded the interval interior SCI of heavily distribution that drops on that stores among this UE set by step.
In step 740, UTRAN reclaims SCI, by the SCI valid interval behind Broadcast Control Channel all UE broadcasting recovery SCI in the sub-district.Simultaneously, also stop to send heavy assignment information to UE by dedicated channel.At above-mentioned case, UTRAN reclaims SCI valid interval (9,18) behind SCI by all UE broadcasting of Broadcast Control Channel in the sub-district.
In the present embodiment, UE beyond service area may not receive any broadcast message, and these UE can keep the SCI of storage by the time limit, so, the SCI that UTRAN reclaims must just can reuse later at 6 hours, occurred with the situation that prevents the corresponding different configuration items of same SCI in UTRAN and the UE.Be not difficult to find, the present embodiment and first embodiment are also basic identical, difference only is, first embodiment is that UTRAN passes through Dedicated Control Channel, will weigh assignment information and valid interval incidentally in downlink signaling, sends to that all are in the UE of point-to-point communication state in the sub-district, and in the present embodiment, UTRAN is by all UEs broadcasting of Broadcast Control Channel in the sub-district, or simultaneously also by Dedicated Control Channel, will weigh assignment information and valid interval sends to UE.But UTRAN can send to UE with the heavy assignment information of all SCI equally, make before UTRAN changes the SCI valid interval, upgrade in time the SCI of relevant configuration item of UE, can effectively avoid UE not carry out the situation generation of unnecessary deletion because of the configuration item that obtains the heavy assignment information of SCI and will part store.
The method that SCI heavily distributes in the mobile communication system of fifth embodiment of the invention as shown in Figure 8.
Step 810 is identical with step 710.
Step 820 is identical with step 720.
In step 830, the UTRAN of network side needs heavily to distribute involved SCI after reshuffling certain configuration item, and the valid interval that will weigh assignment information and SCI is by Broadcast Control Channel all UE broadcasting in the sub-district.This step is basic identical with step 730, difference only is, heavy assignment information in the heavy assignment information described in the step 730 and the first embodiment of the present invention is identical, and heavy assignment information in this step and the heavy assignment information in the second embodiment of the present invention are identical.Therefore, UE is behind the valid interval that receives heavy assignment information and SCI, and the method described in 540 is upgraded the interval interior SCI of heavily distribution that drops on that stores among this UE set by step
Step 840 is identical with step 740.
