Embodiment

Below in conjunction with the accompanying drawing in the embodiment of the present invention, the technical scheme in the embodiment of the present invention is clearly and completely described, it is clear that described embodiment is only the present invention one Divide embodiment, rather than whole embodiments.Based on the embodiment in the present invention, the every other embodiment that those of ordinary skill in the art are obtained under the premise of creative work is not made belongs to the scope of protection of the invention.

Fig. 2 show the logical architecture figure of MBMS in Long Term Evolution (long term evolution, LTE) network.As shown in Fig. 2 MBMS frameworks 200 include following network element：BroadCast MultiCast Service center (Broadcast-Multicast Service Centre, BM-SC) 201, MBMS gateways (MBMS Gateway, MBMS-GW) 202, mobile management network element (Mobility Management Entity, MME) 203, multiple cell/multicast coordination function entity (Multi-cell/multicast Coordination Entity, MCE) 204 and Evolved UTRAN (Evolved Universal Terrestrial Radio Access Network, E-UTRAN) 205.

Wherein, BM-SC 201 belongs to operation layer network element, is the entrance of content provider, for providing foundation and initiation, the session control etc. that the convergence and transmission, the mandate (generation and transmission of key) of user, MBMS of business are carried.BM-SC 201 can also realize synchronous between E-UTRAN205 simultaneously.

MBMS-GW 202, as a node between BM-SC 201 and E-UTRAN 205, is the access gateway of network, the signaling related to session for being responsible for the related message of processes user data.

MME 203 is chain of command network element node, is primarily involved in MBMS session control management.

For single MBMS, MCE 204 is mainly used in the scheduling of business, suitable resource parameters such as (including) frequency, times is distributed, multimedia broadcast multicast SFN (Multicast Broadcast Single Frequency Network, MBSFN) transmission is carried out.For multiple MBMSs, MCE 204 needs to coordinate its corresponding multiple MBSFN transmission, includes size, the use of Radio Resource etc. in MBSFN regions, so as to reasonably, efficiently use resource.

Wherein, MBSFN transmission is a kind of MBMS Synchronous Transfer Mode.Each MBMS area can cover multiple MBSFN regions, one SAI of each MBMS area correspondence.Each MBSFN regions can cover multiple eNB again, and therefore, each eNB can correspond to one or more SAI.Further, since each eNB also can simultaneously by multiple MBSFN region overlays, and each MBSFN area using a frequency come synchronous transmitting data, i.e. each corresponding system frequency of MBSFN area.Therefore, each eNB can correspond to one or more frequencies.

In the embodiment in fig. 3 a, E-UTRAN 205 includes serving BS eNB1 and adjacent area Base station, for example, eNB2 and eNB3.Wherein, eNB1 is covered by MBSFN first areas (MBSFN area 1), and eNB2 is covered by MBSFN second areas (MBSFN area 2), and eNB3 is covered by the regions of MBSFN the 3rd (MBSFN area 3).However, the present invention is not limited thereto, in other embodiments, any eNB can be by multiple MBSFN region overlays.

Wherein, the configuration information of our station and the configuration information of neighbor base station are configured with eNB1, the configuration information includes the corresponding SAI and frequency in base station.For example, eNB1 configuration information or the configuration information of neighbor base station can be as any such as following form：{ SAI1-f1 }, { SAI1, SAI2-f1 }, { SAI1-f1, f1 } or { SAI1, SAI2-f1, f1 }.{ SAI1-f1 } represents that the base station is corresponding with a SAI (i.e. SAI1), and corresponding with a frequency (i.e. f1)；{ SAI1, SAI2-f1 } represents that the base station is corresponding with multiple SAI (i.e. SAI1 and SAI2), and corresponding with a frequency (i.e. f1)；{ SAI1-f1, f1 } represents that the base station is corresponding with a SAI (i.e. SAI1), and corresponding with multiple frequencies (i.e. f1 and f2)；{ SAI1, SAI2-f1, f1 } represents that the base station is corresponding with multiple SAI (i.e. SAI1 and SAI2), and corresponding with multiple frequencies (i.e. f1 and f2).

Fig. 3 B show the signaling interaction diagram of MBMS communication means according to an embodiment of the invention.Fig. 3 B will be described with reference to Fig. 3 A.This method is applied to UE 206 handoff procedure, specifically includes following steps：

S301, the serving BS eNB1 of current area broadcast the configuration information of the base station and neighbor base station by system broadcast message SIB15 to UE206.Configuration information includes eNB1, eNB2

Corresponding relation between the SAI and frequency of eNB3 SAI lists, frequency list and each base station.For example, eNB1 correspondence SAI1 and f1, eNB2 correspondence SAI2 and f2, eNB3 correspondence SAI3 and f2.ENB1 broadcasts SAI row by system broadcast message SIB15 to UE 206

The corresponding relation of table { SAI1, SAI2, SAI3 }, frequency list { f1, f2 }, and SAI and frequency is { SAI1-f1；SAI2—f2；SAI3—f2}.

S302, UE 206 judges the SAI whether its SAI preserved belongs in the list of frequency of eNB1 broadcast.

For example, the USD that UE 206 is preserved includes interim mobile group identification (Temporary Mobile Group Identity, TMGI) and one or more SAI corresponding relation.TMGI is used for the type for indicating UE business interested.UE 206 listen to E-UTRAN broadcast SIB15 message, and judge oneself preserve USD in SAI whether be SIB15 broadcast list of frequency in SAI.If it is, UE 206 reads the corresponding frequencies of the SAI in SIB15 message.

Specifically, in this example, it is assumed that belonging to the SAI of SAI lists only corresponds to a frequency, UE206 reads a corresponding frequency.As an example it is assumed that UE is interested in a MBMS, the corresponding relation preserved in its USD is { TMGI1-SAI2 }.After UE uppicks broadcast message SIB15, SAI2 is judged in SIB15 list of frequency, and know that the corresponding frequencies of SAI2 are f2 according to corresponding relation.However, the present invention is not limited thereto, in other embodiments, if belonging to the multiple frequencies of SAI correspondences of SAI lists, or, if multiple SAI in the USD that UE 206 is preserved belong to frequency list, UE 206 needs to read all frequencies corresponding with SAI in SIB15 message.

S303, UE 206 indicates that message reports the first information to eNB1 by MBMS interest, and the first information includes the corresponding relation between the business information of UE MBMSs interested and the frequency of the broadcast business.That is, the MBMS interest that UE 206 is reported indicates to include the above-mentioned corresponding frequencies of SAI in message, in addition, MBMS interest indicates also to include the business information of MBMS interested UE in message.Business information is used for the type for indicating UE MBMSs interested, for example, business information includes TMGI, or other can identify the mark of MBMS type.

For example, after it is f2 that UE 206, which determines the corresponding frequencies of SAI2, being reported { TMGI1-f2 } to eNB1.So, currently received for the UE eNB1 serviced after the MBMS interest instruction message that UE is reported, it is possible to know the business that each UE is interested in which MBMS and these are interested can be broadcasted on which frequency.

S304, neighbor base station (for example, eNB2 and eNB3) reports the second information to serving BS eNB1, and the second information includes the MBMS information and its corresponding frequency point information that adjacent area eNB oneself is broadcasted.

For example, eNB2 and eNB3 the broadcasting MBMS business all on frequency f2.Specifically, eNB2 broadcasts the MBMS with TMGI1 on frequency f2, and eNB3 broadcasts the MBMS with TMGI2 on frequency f2.Therefore, the business and its corresponding frequency point information for oneself broadcast that eNB2 is reported are { TMGI1-f2 }, and the business and its corresponding frequency point information of oneself broadcast that eNB3 is reported are { TMGI2-f2 }.

The second information that S305, eNB1 are reported according to the UE first information reported and adjacent area eNB, is the destination service eNB of UE selection switchings, and UE is switched into destination service eNB.

For example, the first information that UE is reported includes { TMGI1-f2 }, and the second information that eNB2 is reported includes { TMGI1-f2 }, and the second information that eNB2 is reported includes { TMGI2-f2 }.Therefore, eNB1 determines that eNB2 can broadcast the MBMSs with TMGI1 interested of UE 206 on frequency f2, and UE 206 is switched into eNB2 accordingly.

Therefore, when different base station broadcasts different business on same frequency, in the prior art, UE only reports the frequency corresponding to the SAI for belonging to SAI lists, such as frequency f2.Due to eNB2 and eNB3 all on frequency f2 broadcasting MBMS business, and only eNB2 broadcasts business interested UE on frequency f2.If UE is switched to eNB3 by eNB1, because eNB3 does not broadcast UE business interested on frequency f2, the business that UE can be caused interested is interrupted, and influences Consumer's Experience.If that is, UE only reports the frequency corresponding to the SAI for belonging to SAI lists, not ensuring that the base station that UE is switched to broadcast UE business interested.The invention provides a kind of method of holding MBMS business continuance.Pass through this method, before the eNB serviced for UE does switching selection, need to consider the corresponding relation between the business information of UE MBMSs interested and the frequency of the broadcast business, need to consider the business and its corresponding frequency point information that adjacent area eNB oneself is broadcasted simultaneously, and UE is switched to suitable target eNB by the result matched according to both, so as to ensure that the continuity of UE MBMSs interested in handoff procedure.

Alternatively, the second information that the first information and adjacent area eNB that eNB1 can be reported according to UE are reported, prioritizing selection can broadcast the eNB of UE as much as possible business interested as target eNB, and UE is switched into target eNB.In other words, the target eNB that selects broadcasts the UE MBMSs interested of the first quantity, and first quantity is no less than other any neighbor base stations broadcast UE in multiple neighbor base stations in addition to target BS MBMS interested quantity.

In another embodiment, UE206 can determine multiple frequencies according to the SAI for belonging to SAI lists.Corresponding relation between multiple frequencies of the business information of MBMS interested and the broadcast business is all reported eNB1 by UE 206, such as { TMGI1-f2, f3 }.

In yet another embodiment, UE206 is interested in multiple MBMSs, and the corresponding relation between the frequency of the business information of each business in MBMS interested and the broadcast business is reported eNB1 by UE 206.For example, UE206 is interested in two MBMSs.The two MBMSs have TMGI1 and TMGI2 respectively, and TMGI1 correspondence frequency f1, TMGI2 correspondence frequencies f2 is determined according to SAI.Therefore, UE 206 reports { TMGI1-f1 } and { TMGI2-f2 } to eNB1.

When eNB2 and eNB3 all broadcasting services on frequency f1 and f2, for example, eNB2 broadcasts the business with TMGI1, and business of the broadcast with TMGI2 on frequency f2 on frequency f1, and eNB3 broadcasts the business with TMGI2 on frequency f1 and f2.Existing skill Art, because eNB1 only reports frequency f1 and f2, and eNB3 broadcasts a part of MBMS interested UE only on frequency f1 and f2, destroys the business continuance with TMGI1.However, using the method for the present invention, eNB2 and eNB3 report the second information { TMGI1-f1, TMGI2-f2 } and { TMGI2-f1, f2 } respectively.Therefore, the information that eNB1 can be reported according to UE and neighbor base station, determines that eNB2 is broadcasting all business interested of UE, and UE is switched into eNB2 accordingly, it is ensured that the continuity of all business interested of UE.

Fig. 4 show MBMS according to embodiments of the present invention communication means flow chart, and this method is performed by the base station (such as eNB1) of current area.Fig. 4 will be described with reference to Fig. 3 A and Fig. 3 B.

S401, first base station obtains the first information that UE is reported, and the first information includes the corresponding relation between UE MBMS interested business information and the frequency of the broadcast business.

S402, first base station obtains the second information that multiple neighbor base stations of the first base station are reported, and second information that each neighbor base station is reported includes the corresponding relation between the neighbor base station MBMS information broadcasted and the frequency for broadcasting the business.

S403, first base station selects the second base station according to the first information and second information from the multiple neighbor base station, and the UE is switched into second base station.

Alternatively, the MBMS interested UE of the quantity of the second base station broadcast first, other any neighbor base stations that first quantity is no less than in the multiple neighbor base station in addition to second base station broadcast UE MBMS interested quantity.

Therefore, serving BS reports the second information that the first information and neighbor base station are reported to have selected one for UE according to UE can broadcast the target BS of UE business interested, it is ensured that the continuity of MBMS interested in handoff procedure UE.

Fig. 5 A to Fig. 5 E show that neighbor base station (e.g., eNB2) according to embodiments of the present invention reports the concrete mode of the second information.

In Fig. 5 A embodiment, the information mutual communication between adjacent eNB is realized by strengthening the eNB config updates step (Configuration Update procedure) of existing X2 interface.For example, the business that adjacent area eNB oneself broadcast is carried in above-mentioned second information, i.e. eNB config updates request message and its corresponding frequency letter are carried in eNB config updates request (eNB configuration update request) message that eNB2 is sent to eNB1 Breath.ENB1 is acknowledged receipt of after config update request message, and replying eNB config updates to eNB2 responds (eNB configuration update response) message.

In Fig. 5 B embodiment, the X2 interface modification process (X2modify procedure) new by defining realizes the information mutual communication between adjacent eNB.For example, carrying the business and its corresponding frequency point information that adjacent area eNB oneself broadcast is carried in above-mentioned second information, i.e. X2 modification request messages in X2 modification request (X2modify request) message that eNB2 is sent to eNB1.ENB1 is acknowledged receipt of after X2 modification request messages, and X2 modification response (X2update response) message is replied to eNB2.

In another embodiment, by dispatching eNB MCE come the relevant information between indirect interaction adjacent eNB.In Fig. 5 C embodiment, the base station (such as eNB1 and eNB2) of neighbor cell is by identical MCE management and running, then eNB2 and MCE can pass through M2 Interface Flowcharts, such as M2 interfaces Establishing process (M2setup procedure), to realize the information mutual communication between adjacent eNB.However, the present invention is not limited thereto, the information mutual communication between eNB can be also realized using other idiographic flows of M2 interfaces.

In Fig. 5 C example, the M2 interfaces that eNB2 is sent to MCE set up in request (M2setup request) message the business and its corresponding frequency point information that above-mentioned second information, i.e. M2 interfaces set up carrying adjacent area eNB oneself broadcast in request message of carrying.MCE acknowledges receipt of M2 interfaces and set up after request message, replys M2 interfaces to eNB2 and sets up response (M2setup response) message.

Then, the second information can be handed down to eNB1 by MCE by MBMS schedule informations flow.For example, carrying above-mentioned second information in the MBMS schedule informations (MBMS scheduling information) that MCE is sent to eNB1.ENB1 is acknowledged receipt of after MBMS schedule informations, and MBMS schedule information response messages are replied to MCE.

In Fig. 5 D embodiment, the base station (such as eNB1 and eNB2) of neighbor cell then can realize the information mutual communication between eNB between eNB in different regions, therefore by different MCE management and running indirectly by the interaction between different MCE.Due to not having direct interface to connect between MCE, therefore interacting between MCE needs to interact the forwarding of information indirectly by connecting MCE MME.

In figure 5d, similarly, the M2 interfaces that eNB2 is sent to MCE2 set up in request message the business and its corresponding frequency point information that above-mentioned second information, i.e. M2 interfaces set up carrying adjacent area eNB oneself broadcast in request message of carrying.MCE2 acknowledges receipt of the foundation of M2 interfaces After request message, reply M2 interfaces to eNB2 and set up response message.

Information exchange between MCE2 and MME can use M3 Interface Flowcharts, for example, M3 interfaces Establishing process (M3setup procedure).For example, MCE2 sends M3 to MME sets up request (M3setup request) message, the M3 sets up request message and carries above-mentioned second information.MME acknowledges receipt of M3 and set up after request message, replys M3 to MCE2 and sets up response (M3setup response) message.

The replacement flow (reset procedure) that information exchange between MME and MCE1 can be initiated using MME.For example, MME is sent by M3 interfaces to MCE1 resets (reset) message, the replacement message carries above-mentioned second information.MCE1 is acknowledged receipt of after replacement message, and replying M3 to MME resets confirmation (reset acknowledge) message.

Finally, similarly, the second information can be handed down to eNB1 by MCE1 by MBMS schedule informations flow.For example, carrying above-mentioned second information in the MBMS schedule informations that MCE1 is sent to eNB1.ENB1 is acknowledged receipt of after MBMS schedule informations, and MBMS schedule information response messages are replied to MCE.

In other embodiments, if MCE1 and MCE are connected on different MME, need to forward above-mentioned second information between MME by the S10 interfaces between MME, will not be repeated here.

In Fig. 5 E embodiment, the information mutual communication between adjacent eNB is realized by the switching flow of X2 interface.For example, eNB1 sends handover request (handover request) message by X2 interface to eNB2, the handover request message includes being used to indicate the configured information that eNB2 reports second information to eNB1.ENB2 is acknowledged receipt of after handover request message, handoff response (handover response) message is replied to eNB1 according to the configured information, the switching response message includes above-mentioned second information, that is, the business oneself broadcasted and its corresponding frequency point information are reported eNB1 by eNB2 by switching response message.

Fig. 6 show a kind of flow chart performed by UE of the MBMS communication means provided according to embodiments of the present invention.Fig. 6 will be described with reference to Fig. 3 A and Fig. 3 B.

S601, UE report the first information to first base station, so that the second information that the first base station is reported according to the first information and multiple neighbor base stations selects the second base station from the multiple neighbor base station.For example, the MBMS interest that UE carries the first information by being sent to eNB1 indicates message.Wherein, the first information includes the corresponding relation between UE MBMS interested business information and the frequency of the broadcast business.And it is each Second information that neighbor base station is reported includes the corresponding relation between the neighbor base station MBMS information broadcasted and the frequency for broadcasting the business.Therefore, the second information that eNB1 is reported according to the first information and multiple neighbor base stations selects the second base station, such as eNB2 from the multiple neighbor base station.

S602, UE receive the switching command that the first base station is sent, to switch to second base station according to the switching command.

Optionally, the MBMS interested UE of the quantity of the second base station broadcast first, other any neighbor base stations that first quantity is no less than in the multiple neighbor base station in addition to second base station broadcast UE MBMS interested quantity.For example, eNB1 determines that eNB2 can broadcast UE all MBMS interested by the first information and the second information, then the UE is switched into eNB2.

Fig. 7 A and Fig. 7 B show a kind of flow chart performed by neighbor base station (such as eNB2) of the MBMS communication means provided according to embodiments of the present invention.Fig. 7 A will combine Fig. 5 A to Fig. 5 D to describe；Fig. 7 B will combine Fig. 5 E to describe, and will not be repeated here.
