Embodiment

To at length be introduced the preferred embodiments of the present invention now, the accompanying drawing illustrated that its example is being followed.As possible, run through the identical reference number of this accompanying drawing and will be used to relate to identical or similar part.

Fig. 4 illustrates the example of MCCH information transmission scheme.MCCH is the example of broadcast message.More particularly, provide the UTRAN of MBMS service MCCH information to be sent to a plurality of UE via MCCH.Periodically send this MCCH information according to modification cycle and repetition period.In addition, this MCCH information can be divided into critical information and non-critical information.Therefore, can during each modification cycle and repetition period, freely revise this non-critical information and be used for transmission.On the contrary, can only during the modification cycle, revise this critical information.In other words, this critical information was sent once by each repetition period, and can only send the critical information of this modification in the modification cycle at first.

In addition, MCCH information refers to MBMS and relevant control messages (for example, Xiang Guan RRC message).This MCCH information comprises unmodified information on services (USI) and point-to-multipoint RB information and the visit information of information on services (MSI), MBMS that MBMS revises.Among these MCCH information, this access information message can be classified as non-critical information, and other message can be classified as critical information.

When UTRAN sends all message be included in the MCCH information, and if this message when comprising the information relevant with service specified, so, the MBMS transmission identifies and is included in this message.At length, this MBMS transmission sign comprises MBMS session identification and MBMS service identifiers.When UTRAN transmits MBMS MSI message, this message comprise MBMS transmission sign with the relevant information of service that identifies corresponding to this transmission.

In addition, this UTRAN periodically sends data via MBMS notification indicator channel (MICH), as in Fig. 3 illustrated.Here, these data comprise with whether MCCH information is updated relevant information during the modification cycle.If UE wishes to receive only certain MBMS service, before the specific conversational services of beginning, UE does not receive data via MTCH not via MCCH yet, periodically receives data but replace via MICH so.In the application's description, upgrade MCCH information and refer to generation from MCCH information, add, revise or remove particular items.

Whether upgrade MCCH information in order to notify during the modification cycle, this UTRAN sends data via MICH and MSI message.This MSI message is included in the identification information of all services of the current area that is modified during the corresponding modification cycle, and the relevant information of work that is used to subscribe the UE of corresponding service.As identifying information, use MBMS transmission sign.Here, this MBMS transmission sign can comprise the MBMS service identifiers that is used for the order special services, and/or the MBMS session identification that is used for the specific session of the specific service of order can combine with the MBMS service identifiers.

In addition, the identification information of unmodified service can be sent via USI message during the modification cycle.Here, the MBMS of corresponding service transmission sign is used as identification information.

When specific MBMS service conversation was activated, this UTRAN sent notification indicator (NI) via MICH.This NI receives data to the UE indication that hope receives specific MBMS service from MCCH.After receiving NI via MICH, this UE is as receiving data on MCCH during the modification cycle of appointment indicating among the NI.When receiving data on MCCH, this UE receives MSI message and wishes that at first to determine whether it MBMS service that receives is modified during the corresponding modification cycle.At this moment, if this MBMS service is modified, so, this UE obtains the MCCH information of modification.With regard to UE, this UE is received in MSI message and the USI message that sends during the modification cycle, and a series of all services that provide in current area during the corresponding modification cycle can be provided.

If this UE wishes that so, this UE can receive the MCCH information that comprises RB information on MCCH, and uses the MCCH information that receives that point-to-multipoint RB is distributed to UE by using point-to-multipoint RB to receive certain MBMS service.After this UE finished configuration point-to-multipoint RB, this UE can continue to receive data on MTCH shines upon SCCPCH to it, and obtained the data of the MBMS service that transmits on MTCH.

This UTRAN can send data discontinuously on MTCH.As in Fig. 3 illustrated, this UTRAN can periodically send scheduling message to UE on the MBMS of SCCPCH scheduling channel (MSCH).Here, this scheduling message is provided at the transmission starting point and the transmission cycle of the MBMS data that send during dispatching cycle.For this reason, this UTRAN should be in advance will offer the dispatching cycle of schedule information UE.

Table 1 illustrates according to the MSI that does not have the service modification of the embodiment of the invention and the composition of USI message.

[table 1]

In an embodiment of the present invention, this USI message can be during each USI cycle (UP), revised, and this MSI message can be during each MSI cycle (MP), revised.The length of this UP be this MP length S doubly.According to table 1, the length of this UP is three (3) double-lengths of the length of this MP.Here, S is three (3).In other words, (a 1) UP comprises three (3) MP.In addition, the length of this UP and MP can be represented as the time interval.These time intervals can be identical length or different length.

As illustrational by table 1, the information of unmodified service is classified and is grouped among three MP.Unlike the prior art, USI message is sent in all relevant with all unmodified services among single MP information here, sends the part (the perhaps part of appointment) of the information of this unmodified service according to the USI message of the embodiment of the invention.In order to realize these, the current all MBMS services that are among the session are divided into the group (for example, G1, G2, G3) of S number in corresponding sub-district, and each group is assigned to different MP.Equally, the MP of S number comprises UP.

For example, this service can be divided into groups in one way, makes service 1-5 belong to G1, and service 6-10 belongs to G2, and service 11-14 belongs to G3.More particularly, reference table 1, service 1-5 is assigned to the MP#1 of UP#1, and service 6-10 is assigned to the MP#2 of UP#1, and service 11-14 is assigned to the MP#3 of UP#1.If certain service is assigned to the specific MP of UP, so, can be in an identical manner with specific dispensing applications in follow-up UP.In addition, keep such distribution, till stopping this corresponding service conversation.

According to embodiments of the invention, this UTRAN will comprise that the MSI and the USI message of the information on services of corresponding sub-district send to UE.Before can receiving MSI and USI message, this UE obtains and S the information that group is relevant.After this, this UE receives a plurality of message according to S group adjoining land.Here, each of this MSI or USI message perhaps differently placed the length in this cycle corresponding to the time interval.

Table 1 illustrates the situation that does not have modification or change in any one of MP.That is to say,, in MP#1 to MP#6, do not revise (for example, MSI message is empty) as in table 2 illustrated.Thereby because service is not revised, this information on services is included in the USI message, and is not included in the MSI message.Here, the information that this service (for example, service 1, service 8, service 14) expression sends in MSI message and/or USI message with specific MP/UP.

Alternatively, table 2 illustrates a kind of situation, and except in MP#5, the indication service is revised in each MP here.

[table 2]

Situation as in the prior art if indication is to the modification or the variation of corresponding information on services in specific MP, sends this MSI message in specific MP.That is to say that do not consider that this information on services is included in which service packet (for example, G1, G2, G3), this MSI message comprises the service identifiers information of the information on services of modification.But this USI message that sends in specific MP does not comprise the information on services of modification, but only comprises the information on services of the unmodified service of distributing to specific MP.

For example, reference table 2 is by the service 2 of MP#1 and service 8 indications to the modification of information on services.In addition, be by the service 2,3 of MP#2 and 5 indications to the modification of information on services, and be by the service 11 of MP#3 and 14 indications the other modification of information on services.In MP#1,, be not included in the USI message of MP#1 with the information on services of service 2 relevant modifications, but only be included in the MSI message of MP#1 because service 2 information have been assigned to MP#1.In addition, because service 8 information are assigned to MP#2, be included in the MSI message of MP#1 with the information on services of service 8 relevant modifications, and unmodified service 8 information are included in the USI message of MP#2.Here, except subsequent cycle (that is, MP#2) revise once more outside service 8 information, when a minute timing, unmodified and comprise service 8 information.

In MP#2, because the modification of serving 2 information is indicated in MP#2, service 2 information of this modification are included in the MSI message of MP#2.Even 2 information of serving are assigned to MP#1,2 information of serving are not included in the USI message of MP#1, because revise service 2 information in MP#1.The information on services of this modification is included in the MSI message of corresponding M P.

In MP#3, because distribution services 11 and 14 information in MP#3, the information on services that their are revised is included in the MSI message, and because they are not modified, remaining service 12 and 13 information is included in the USI message.

With respect to UP#2, in MP#4 indication to serving the modification of 10 information and service 12 information, and in MP#6 in addition indication to serving the modification of 8 information and service 12 information.Thereby the information on services of these modifications is included in the MSI message of corresponding M P.Here, because service 10 information that indication is revised in MP#4, the information on services of this modification is included in the MSI message of MP#4, and simultaneously, divides timing when, and service 10 information of this modification are included in the USI message of MP#5.In addition, because service 12 information of revising are included among MP#4 and the MP#6, this service is included among the MSI of corresponding M P.In addition, because service 12 information of revising are included in the MSI message of MP#6, it is not included in the USI message of MP#6.At last, service 8 information that indication is revised in MP#6, thereby service 8 information of this modification are included in the MSI message of MP#6, and be included in the USI message of MP#5 of distribution.

In an embodiment of the present invention, the MCCH information that sends during each modification cycle only sends the information on services that is included in MSI and the USI message in corresponding modification during the cycle.For example, the message that sends on MCCH (for example, MBMS point-to-multipoint RB information, MBMS general information, MBMS visit information are also referred to as MCCH information) only be included among the MP#6 MCCH information relevant with the service that sends via MSI and USI message 8,11,12,13 and 14.As another embodiment of the present invention, can be included in the MCCH information of all services among the UP that UE belongs in the information that on MCCH, sends during each modification cycle.

Table 3 illustrates when starting or stop the session of special services, how to send the example of service-specific information.

[table 3]

When the session of specific service was activated, this UTRAN gave group with specific service assignment.After this, this UTRAN comprises the service identifiers of specific service in the MSI of specific MP message.In addition, this UTRAN also comprises the service identifiers of specific service in the USI message of specific service assignment to its MP.If the MP of MSI message is identical with the MP of USI message, the service identifiers of the service that this is specific only is included in the MSI message of MP.

As in table 3 illustrated, if that serves 15 sessions begins to occur among the MP#2, this UTRAN comprises service 15 information in the MSI of MP#2 message, and serves 15 service identifiers and be included in first group the USI message, wherein will serve 15 information distribution to first group in a UP.Because the session of service 15 begins at MP#2,15 information of serving are not included among the MP#1, but are included in from the USI message that MP#4 begins.

For the session of the service 17 that begins from MP#2,17 information of serving are included in the MSI message of MP#2.In addition, distribution services 17 information are to this UP second group (that is, MP#2, MP#5) owing to this UTRAN, and 17 information of serving are included in the USI message of MP#5.

As for service 16 sessions that begin in MP#4,16 information of serving are included in the MSI message of MP#4.In addition, distribution services 16 information are to this UP the 3rd group (that is, MP#3, MP#6) owing to this UTRAN, and 16 information of serving are included in the USI message of MP#6.

But if the session of indication service 3 stops in MP#2, this UTRAN comprises service 3 in the MSI of MP#2 message, and gives its first group (that is, to remove service 3 information in MP#1) from serving 3 initial allocation.After removing, in follow-up corresponding M P, no longer send service 3 information.But (that is, MP#1), the identification information of service 3 is included in the USI message of MP#1 because service 3 is assigned to first group.

In addition, if in the session of MP#3 indication service 11 stops, this UTRAN comprises service 11 information in the MSI of MP#3 message, and gives its 3rd group and remove service 11 information from serving 1 initial allocation.After removing, in follow-up corresponding M P, no longer send service 11 information.For example, as shown in table 3, after the session of service 11 stops in MP#3, follow-up corresponding M P, that is, MP#6 does not comprise service 11.But because service 3 is allocated in advance to first group, the identification information of service 3 is included in the USI message of MP#1.

In addition, if the session of indication service 10 stops in MP#4, this UTRAN comprises service 10 information in the MSI of MP#4 message, and removes service 10 information from serve second grouping of 10 initial allocation to it.After removing, in follow-up corresponding M P, no longer send service 10 information.

When one group of identifying information is used for MSI message, because can broadcast all available MBMS service identifiers to support the UE from other sub-districts during the modification cycle, the relevant information that belongs to all services of this grouping can be included in the USI message.Therefore, if UE from other sub-district, after receiving USI and MSI message, this UE is appreciated that this transmission group character.

Fig. 5 illustrates the process that is obtained information on services according to the present invention by UE.In an embodiment of the present invention, this UE must receive MSI message and USI message for the whole duration of work of this UP, so that obtain the information on services of designated cell fully.This UE receives this message during whole UP, with when this UE moves to different sub-districts, at first activate this MBMS service, obtains all information on services of this sub-district, perhaps the mistake that occurs when managing service information.After receiving all information on services, this UE can only receive MSI message to determine the state of this information on services., there be not moving or mobility of this UE here, needn't go to carry out above operations/processes.

With respect to the service information acquisition process of this UE, this UTRAN sends to this UE with the length of this UP on Broadcast Control Channel (BCCH) or on MCCH.If the length of this UP is sent on MCCH, this UTRAN can use any one (it is periodically sent) of MSI message and USI message, to send the length of this UP.Preferably, the length of this UP will be included in the USI message, and if the length of this UP be modified/change, the length of the modification of this UP will be included in the MSI message.

Fig. 5 is described in detail as follows.In order to obtain the information on services of specific cell fully, this UE receives information via MCCH, and receives this MSI message and USI message during the modification cycle of appointment.Then, the content of this UE store M SI and USI message (for example, information on services).Use this MSI and USI message, can obtain the length of this UP.Here, the length of this UP can be represented as S1, and the value of S1 is corresponding to the multiple in the cycle of modification.The value of this UE storage S1, and m is set to S1 (m=S1) (S10).

Subsequently, this UE receives MSI message and USI message during the subsequent modification cycle, and the content of store M SI and USI message.Use this MSI message or USI message, this UE obtains the length of this UP.Here, this UP can be represented as S2, and the value of S2 is corresponding to the multiple in the cycle of modification.At this moment, m is set to m-1 (m=m-1) (S20).

After S20, this UE determines that whether the value of S2 is identical (S30) with the value of S1.If the value of S2 is different from the value of S1, this UE is provided with different S1 values by the value of replacing S1 with the value of S2.Store the S1 value of this replacement, and m is re-set as S1.Outside the MSI and USI message (that is, the MSI of current MP and USI message) except nearest storage, this UE deletes or removes all previously stored MSI and USI message then.After this, this UE re-executes the operation of S20.

Alternatively, if the value of S2 is identical with the value of S1, then, this UE determines further whether the value of m is " 0 ".If the value of m is not equal to " 0 ", this UE re-executes the operation (S50) of S20 then.But if the value of m equals " 0 ", it represents the MSI of this storage and all information on services that USI message comprises corresponding sub-district so, and its expression does not need to combine the more service information (S60) that receives with corresponding sub-district.
