Embodiment
The technical scheme of the embodiment of the invention comprises the steps: as shown in Figure 1
Step 1:UE sends the service handoff request message of carrying purpose multicast services information and user totem information; UE can send service change solicited message to network side according to the multicast services information of preserving in advance, also can send service change solicited message to network side according to the multicast services information that obtains from air interface.
Service handoff request message can be carried: purpose multicast services information and user totem information.
Purpose multicast services information can comprise: purpose multicast services sign, and selectively comprise association identification.The purpose multicast services is designated the purpose multicast services information of the purpose multicast correspondence that handover operation that UE initiates determines; Provide under the situation of carrying service in the MBMS service, purpose multicast services sign can be by IP (network layer protocol) multicast address and the common sign of APN (APN); Perhaps identify by TMGI (Temporary Mobile Group Identity).Purpose multicast services information can also comprise association identification, the sign whether former multicast services of the indication that promptly sets in advance and purpose multicast services be related; The set-up mode of association identification can comprise: network side is provided with the related information of former multicast services and purpose multicast services, and this related information is sent to UE by the association identification that sets in advance; Perhaps, by setting in advance, network side can be known the related situation of former multicast services and purpose multicast services.
Related information is the information that concerns between each multicast services of indication that sets in advance, specifically can be according to the reception authority of each different multicast services that set in advance; Perhaps, the relation between the different multicast services of each that sets in advance is determined related information, such as, the identical multicast services of charge is formed related multicast services.Specifically can different multicast services be associated together by a table, network side can by inquire about this table know exist between all multicast services in this table related; Perhaps identify and have association between different multicast services by the mode that different multicast services is disposed identical association identification.
Can also comprise former multicast services information in the service handoff request message, be the multicast services information of the current reception of UE; In service handoff request message, directly comprise former multicast services information, can accelerate the processing speed of network side; And under the current situation that receives a plurality of multicast services simultaneously of UE, inform the specific former multicast services information that needs to switch multicast services to network side.
In service handoff request message, do not comprise directly under the situation of former multicast services information that network side can be determined former multicast services information by user ID.Can in service handoff request message, directly send the UE Context identifier, carry user totem information and the former multicast services information of indication.User totem information can comprise: IMSI (IMSI International Mobile Subscriber Identity), user's temporary mark (such as TMSI (Temporary Mobile Subscriber Identity)) or other can be determined the sign of user identity.
In service handoff request message, the also selectable MBMS of being included in service provides the MBMS ability information of the UE under the carrying service scenario.The MBMS ability information of UE, for determining that at network side the former multicast services that need switch does not have related with the purpose multicast services, and need under the situation of the direct initiation of network side at the adding flow process of purpose multicast services the MBMS ability information of the UE that network side is required; The MBMS ability information can comprise: UE supports the bit number that per second is downloaded, and the MBMS ability information of other UE.
Step 2: network side receives the service handoff request message of carrying purpose multicast services information and user totem information that UE sends, according to the particular content of former multicast services information and purpose multicast services information, and the related information that sets in advance determines whether former multicast services is related with the purpose multicast services.Network side can be known the particular content of former multicast services information according to receiving the former multicast services information of serving in the handoff request message; Network side also can be determined former multicast services information according to the user ID that receives in the service handoff request message.
Step 3: if determine that former multicast services is not related with the purpose multicast services, then at the service handoff request message of UE transmission, network side is according to the adding flow processing of existing multicast services; That is, provide under the situation of carrying service, the service handoff request message that UE sends is handled as MBMS context activation request message in the MBMS service; From this group service handoff request message, obtain purpose IP multicast address and APN, determine the UE context of former multicast services again by user ID, therefrom obtain linked NSAPI (related Network Service Access point sign); Afterwards, according to the similar method of adding flow process of existing multicast services, add the purpose multicast services.Network side also can be initiated the flow process of leaving at former multicast services after finishing the adding flow process of purpose multicast services, promptly according to the similar method of flow process of leaving of existing multicast services, leave former multicast services.
Determining under the not related situation of former multicast services and purpose multicast services that network side also can at first directly send the information of indication handoff failure to UE; Afterwards, UE adds the purpose multicast services or leaves former multicast services according to the adding of existing multicast services or leave the similar method of flow process.
Step 4: if determine that former multicast services is related with the purpose multicast services, the operation of then switching multicast services as shown in Figure 2, needs to carry out following steps:
Step 41: the change dump corresponding with former multicast services in the UE context of first network node in the network side on it is the information corresponding with the purpose multicast services, comprise: with former multicast services change dump is purpose multicast services information, be about to former IP multicast address and APN and be replaced by purpose IP multicast address and APN, perhaps former TMGI sign is replaced by purpose TMGI sign; And, be information such as purpose multicast bear ability, coverage with information changes such as former multicast bear ability, coverages.After first network node is finished modification to the information relevant with former multicast services, send multicast services handover success message to UE, this handover success message comprises the TMGI of purpose multicast services, and the UE contextual information of preserving among the modification UE (provide under the situation of carrying service in the MBMS service, this UE contextual information can be MBMS UE contextual information).First network node is and the contextual network node of UE interaction process UE can comprise and carry out the processing of UE context and register two different functional entitys.
Step 42: do not set up at first network node under the situation of multicast services bearer context of purpose multicast services, before execution in step 41, first network node is registered to second network node, and request adds the purpose multicast services.Be specifically as follows: first network node sends login request message to second network node; Second network node sends registration reply message to first network node, and described registration reply message comprises: purpose multicast services information; First network node receives after the described registration reply message, sets up the multicast services bearer context of described purpose multicast services; Described second network node is the upstream node of described first network node, and directly links to each other with first network node, is used to obtain the multicast services content that network provider provides, and this multicast services information is sent to first network node.
Afterwards, network side is set up data transmission channel, specifically can carry out following steps:
Step 43: the information that the first network node UE switches to the purpose multicast services sends to the 3rd network node, comprises purpose multicast services information and user totem information, also selectively comprises former multicast services information.If the 3rd network node is the support purpose multicast services not, then the 3rd network node is initiated register requirement to first network node; If the 3rd network node finds that this UE is last UE that receives former multicast services, then execution in step 45.Described the 3rd network node is the downstream node of first network node, and directly links to each other with first network node, is used for obtaining multicast services information from first network node, and this multicast services information is sent to UE by air interface.
Step 44: the information that the first network node user switches to the purpose multicast services sends to second network node, comprises purpose multicast services information and user totem information, also selectively comprises former multicast services information.If in wireless network inside, the multicast packet source of multicast services is not second network node, and then this second network node also can switch to the user its upstream node of information notification of purpose multicast services.The information that the described second network node UE switches to the purpose multicast services sends to its BMSE upstream node multicast services source.
Step 45: the 3rd network node is initiated de-registration request to first network node.
In order to ensure the unanimity of UE contextual information in each network node, described method can also comprise the steps:
The 3rd network node receives after the purpose multicast services information and user totem information of first network node transmission, and the corresponding informance in the UE context of former preservation is replaced by purpose multicast services information;
Second network node receives after the purpose multicast services information and user totem information of first network node transmission, corresponding informance in the UE context (provide under the situation of carrying service in the MBMS service, be MBMS UE context) of former preservation is replaced by purpose multicast services information.
Above-mentioned two steps can be carried out before UE sends multicast services handover success message by first network node in step 41, also can carry out after UE sends multicast services handover success message by first network node in rapid 41.
Below in conjunction with accompanying drawing, the situation so that the MBMS service provides carrying to serve is described in detail the embodiment of the invention.

Below with UE in one in central authorities, the switching of central authorities between two, three, four and five, to obtain the situation of different multicast services,, the specific implementation of embodiment of the invention method is described in detail respectively as specific embodiments of the invention.
UE is switched to two in central authorities from one in central authorities, and the process that other two multicast services that provide of UE reception central authorities are provided in the network comprises specifically as first embodiment of the present invention:
UE obtains central two multicast services information according to the configuration information of preserving on it, and sends service handoff request message to UPE.The service handoff request message that sends can for:
(purpose multicast services information :) 224.201.10.2 mbs.cm
(UE Context identifier :) 1021
After UPE receives service handoff request message, by zhang sign 1021 about the UE in the service handoff request message, obtain purpose IP multicast address and APN in the purpose multicast services information that the corresponding MBMS UE context that is kept among the UPE: UPE sends according to the IP multicast address in this MBMS UE context and APN (being former IP multicast address and APN) and UE, determine that these two multicast services (two in one in central authorities and central authorities) are association service.Afterwards, UPE is replaced by the IP multicast address in this MBMS UE context, APN (being former IP multicast address and APN) IP multicast address, the APN (being purpose IP multicast address and APN) of two of corresponding central.Owing to existed other UE in the network at the program that receives two in central authorities, then in UPE, preserved the MBMS bearer context of two correspondences of central authorities, from this MBMS bearer context, obtain the TMGI of two in central authorities, and this TMGI is updated in the UE context among the UPE.UPE finishes after the contextual renewal of UE, sends service handover success message to UE.The service handover success message that sends can for:
(result :) success
(TMGI：)123452
After UE receives this service handover success message, learn MBMS service handover success, then the multicast address in the UE context, APN, TMGI are replaced by up-to-date parameter, and begin to attempt obtaining multicast packet from air interface.
After UE sent service handover success message, UPE promptly switched message to SAE anchor and eNodeB transmission UE service with the information notice SAE anchor and the eNodeB of the service of UE switching carrier at UPE; The UE service that sends switch message can for:
(former multicast services information :) 224.201.10.1 mbs.cm
(purpose multicast services information :) 224.201.10.2mbs.cm
(user ID :) 460011234567890
After SAE anchor and eNodeB receive this message, find corresponding UE context, and wherein IP multicast address, APN are changed to the corresponding content of purpose multicast services information, and change corresponding TMGI by user ID and former multicast services information.
After eNodeB had changed the UE context, as if there not being corresponding UE context under the multicast services of learning a correspondence of central authorities, then eNodeB was to the logout flow path of UPE initiation at this MBMS bearer context; UPE is with this eNodeB deletion from the descendant node tabulation of bearer context.
UE is switched to three in central authorities from two in central authorities, and the process that other three multicast services information that provide of UE reception central authorities are not provided in the network comprises specifically as second embodiment of the present invention:
