Need to prove, before entering step 310, source RNC can judge earlier with CN between whether have Iu to be connected corresponding to this UE, if there is Iu to connect corresponding to this UE, then this source RNC sends " migration needs " message to CN in the Iu of this UE connection, and the migration flow process of initiation is same as the prior art; If the Iu corresponding to this UE does not connect, then enter step 310 again.Because in the present embodiment, between source RNC and the CN not the Iu corresponding to this UE be connected, therefore, directly enter this step.This shows, exist source RNC to be connected whether with Iu between the CN by prejudging, if existed Iu to connect then handled by prior art, like this can compatible prior art scheme, make full use of existing equipment, the protection benefits of operators.
Then, in step 320, the Iu that CN sets up this UE according to " Target RNC sign " in the message and corresponding Target RNC connects, and sets up promptly that the signaling at this UE is connected between CN and the Target RNC.CN sends " migration request " message to Target RNC in this Iu connection then.Comprise " source RNC is to the Target RNC transparent vessel " cell in the message.
Then, in step 330, Target RNC is set up the context of this UE and is reserved corresponding resource according to the information in " source RNC is to the Target RNC transparent vessel " cell.Target RNC sends " migration request affirmation " message to CN in this Iu connection then, comprises the result of context foundation and resource reservation in the message.
Then, in step 340, CN by with source RNC between the Iu of this UE be connected to this source RNC and send " migration order " message.
Then, in step 350, carry out transition process, the RNC of service becomes Target RNC by source RNC.
Then, in step 360, Target RNC sends " migration is finished " message to CN.
Then, in step 370, the Iu that discharges between CN and the Target RNC connects.Because before the migration of initiating Serving RNC, do not have corresponding Iu between source RNC and the CN and is connected, therefore, in this step, after the Serving RNC migration of this UE is finished, need to discharge the Iu connection between CN and the Target RNC.
Then, in step 380, the Iu of this UE between source of release RNC and the CN connects.
Then, in step 390, in the RNC of source, discharge the context of this UE.
Be not difficult to find, in the present embodiment, the Iu that elder generation's foundation can be communicated with source RNC and Target RNC is connected, connect the migration that realizes Serving RNC by this Iu, discharging this Iu at last connects, thereby realized the migration of Serving RNC when between source RNC and CN, originally not having Iu to be connected, guaranteed that UE can carry out the Serving RNC migration when professional receiving MBMS.
The 3rd execution mode of the present invention relates to a kind of Serving RNC moving method, in the present embodiment, does not have corresponding Iu to be connected between source RNC and the CN, this connects corresponding to the UE that wants migration service RNC, and, have the Iur interface between source RNC and the Target RNC, and exist Iur to connect.Idiographic flow as shown in Figure 4.
In step 410, when the Serving RNC of UE need move, source RNC by with Target RNC between the Iur of this UE be connected, send " migration request " message to Target RNC, initiate the migration flow process.Comprise " source RNC is to the Target RNC transparent vessel " cell in this message, comprise RAB and the RB configuration information of this UE in this cell.
Need to prove, before entering step 410, source RNC can judge earlier with CN between whether have Iu to be connected corresponding to this UE, if there is Iu to connect corresponding to this UE, then this source RNC sends " migration needs " message to CN in the Iu of this UE connection, the migration flow process of initiating is same as the prior art, with the mutually fusion of realization with prior art; If the Iu corresponding to this UE does not connect, and has the Iur interface between source RNC and the Target RNC, and exist Iur to connect, then enter step 410 again.Because in the present embodiment, between source RNC and the CN not the Iu corresponding to this UE is connected, and have the Iur interface between source RNC and the Target RNC, and have the Iur connection, therefore, directly enter this step.
Then, in step 420, Target RNC is set up the context of this UE and is reserved corresponding resource according to the information in " source RNC is to the Target RNC transparent vessel " cell.Carry out transition process, the RNC of service becomes Target RNC by source RNC.
Then, in step 430, Target RNC by with source RNC between the Iur of this UE be connected, RNC sends " migration is finished " message to the source.
Then, in step 440, the Iur of this UE between source of release RNC and the Target RNC connects.
Then, in step 450, in the RNC of source, discharge the context of this UE.
Because in the present embodiment, carry out Serving RNC by the Iur interface between source RNC and the Target RNC and move needed interacting message, make message need not transfer by CN, need not be connected with Iu between the CN at RNC, therefore, even UE does not have Iu to connect, also can realize the migration of Serving RNC smoothly when receiving the MBMS business.
The 4th execution mode of the present invention relates to a kind of Serving RNC moving method, and present embodiment and the 3rd execution mode are roughly the same, its difference with, in the 3rd execution mode, have the Iur interface between source RNC and the Target RNC, and exist Iur to connect.And in the present embodiment, have the Iur interface between source RNC and the Target RNC, but do not exist Iur to connect.
Specifically, as shown in Figure 5, in step 510, when the Serving RNC of UE need move, source RNC sent " migration request " message to Target RNC, and this message is connectionless information.Comprise " source RNC is to the Target RNC transparent vessel " and " UE sign " cell in should " migration request " message, wherein, source RNC comprises RAB and the RB configuration information of this UE in the Target RNC transparent vessel.Owing to should " migration request " message be connectionless information, therefore, this message need comprise the sign of UE and indicate the UE of this message correspondence, make the Target RNC of receiving " migration needs " message can know that this message is relevant with the Serving RNC migration of which UE, thereby guarantee that this message can correctly be handled.
Then, in step 520, Target RNC is set up the context of this UE and is reserved corresponding resource according to the information in " source RNC is to the Target RNC transparent vessel " cell.Carry out transition process, the RNC of service becomes Target RNC by source RNC.
Then, in step 530, Target RNC sends " migration is finished " message to source RNC.This message is connectionless information, and this message comprises " UE sign " cell, makes this source RNC can know that this " migration is finished " message is relevant with the Serving RNC migration of which UE, thereby this message is made correct processing.
Then, in step 540, in the RNC of source, discharge the context of this UE.
