Embodiment
Below in conjunction with the drawings and specific embodiments, the technical solution of the present invention is further elaborated.
The method that the present invention realizes MBMS service continuity comprises the steps: as shown in Figure 1
Step 101, select target community, UE obtains the configuration information of Target cell.
Step 102, UE moves to Target cell according to configuration information, and receives MBMS in Target cell.
Main thought of the present invention is: UE adopts cell merge or the cell re-selection procedure select target community of clean culture, make UE before moving to Target cell, just get the resource allocation information of MBMS, so after moving to Target cell, just the resource allocation information of direct basis MBMS can receive MBMS, ensure the continuity of MBMS with this; Or, make UE after moving to Target cell, then obtain the resource allocation information of MBMS and receive MBMS, ensure the continuity of MBMS with this.
The configuration information of Target cell at least comprises: Target cell ID; Further, the configuration information of Target cell also comprises: the traffic frequencies configuration information (follow-up abbreviation traffic frequencies configuration information) of the MBMS of Target cell and UE need the service resources configuration information (follow-up abbreviation service resources configuration information) of the MBMS received in Target cell.
Below by specific embodiment, the solution of the present invention is described.
Embodiment one is the method realizing MBMS service continuity for the UE of connected state, and idiographic flow as shown in Figure 2, comprising:
Step 201, cell-of-origin periodically sends a request message to the UE of this community, and request UE reports MBMS list.
Wherein, the MBMS that described MBMS list comprises is the MBMS that UE is receiving; In addition, cycle of sending a request message can be determined by high-level signaling (as BCCH signaling or MCCH signaling) or physics signaling or MACCE (MediaAccessControlControlElement) information in cell-of-origin.
Step 202, after receiving request message, the UE being in connected state judges that whether self is positioned at MBSFN zone boundary, if so, then enters 203, otherwise, enter step 204.
If UE is positioned at MBSFN zone boundary, then represent that UE carries out the interregional movement of MBSFN possibly; If UE is not positioned at MBSFN zone boundary but be positioned at MBSFN region, then represent that UE carries out the movement in MBSFN region possibly.
Judge that the mode whether UE is positioned at MBSFN zone boundary has following two kinds:
One, UE is in cell-of-origin, when judging its signal quality received lower than the threshold value preset, determines self to be positioned at MBSFN zone boundary; Otherwise be positioned at MBSFN region.The described signal received can be BCCH signal, MCCH signal, MBMS channel (MTCH) signal, reference signal (RS) or synchronizing signal (PSS/SSS), the threshold value of often kind of all corresponding signal quality of signal, this threshold value can be one according to practical application, measure the empirical value that obtains;
Two, UE reads the control information of cell-of-origin, carries the mark whether instruction cell-of-origin is community, MBSFN zone boundary, if this mark instruction cell-of-origin is community, community, MBSFN zone boundary, then judge self to be positioned at MBSFN zone boundary in this control information; Otherwise be positioned at MBSFN region.Wherein, above-mentioned control information is: BCCH information, MCCH information or MACCE information.
Except above-mentioned two kinds of modes, UE can also adopt other modes of the prior art to judge, system message as the adjacent cell according to cell-of-origin changes, MCH schedule information (MSI, the MCHSchedulingInformation) information change etc. of adjacent cell MCCH information change or adjacent cell.
Step 203, UE reports MBMS list by measurement report or special RRC signaling or MACCE message to cell-of-origin, UE can also be reported to receive the instruction of MBMS simultaneously.
Wherein, UE is receiving the instruction of MBMS for showing that to network side this UE is the UE possessing MBMS ability.In follow-up flow process, when UE cannot obtain the configuration information (particularly referring to Target cell ID here) of Target cell, network side can help UE to determine Target cell.
Step 204, select target community.
Accept step 202, when UE is not positioned at MBSFN zone boundary, a Target cell is directly selected in cell-of-origin from the MBSFN adjacent cell list self preserved.Wherein, the MBSFN community in MBSFN adjacent cell list and cell-of-origin belong to a MBSFN region, and the MBMS (MBMS namely opened) sent in these MBSFN communities is identical;
Accept step 203, when UE is positioned at MBSFN zone boundary, after cell-of-origin receives measurement report or special RRC signaling or MACCE message, according to its content decision-making go out this UE need to move time, from the neighbor cell of self, select a Target cell.
Step 205, judges whether preserve service resources configuration information in cell-of-origin, if had, then enters step 210, otherwise enter step 206.
Can carry out information interaction between cell-of-origin and Target cell, the configuration information of self can be informed cell-of-origin by Target cell, concrete, and the configuration information of self can be sent to cell-of-origin by X2 interface by Target cell, is preserved by cell-of-origin.Described configuration information comprises Target cell ID, service resources configuration information and traffic frequencies configuration information.Wherein, traffic frequencies configuration information refers to the frequency configuration information that can provide MBMS, if Target cell can not provide MBMS, then corresponding traffic frequencies configuration information does not exist or is designated as nothing.Wherein, X2 interface refers to the interface between enhanced base station (eNB, enhancedNodeB).If do not have X2 interface between the eNB at cell-of-origin and place, Target cell, then described configuration information can be transmitted by other interfaces, and other interfaces described can be: S1 interface, or M2 interface, or M3 interface etc.
When cell-of-origin receives the MBMS list that UE reports, and after have selected the Target cell of carrying out cell merge, judge self whether to preserve UE in Target cell and need the resource allocation information (i.e. service resources configuration information) of the MBMS received, UE needs the resource allocation information of the MBMS received namely to refer to: the resource allocation information of the MBMS comprised in MBMS list.The configuration information of the Target cell that self stores is read in cell-of-origin, whether the MBMS opened that judgement service resources configuration information is wherein corresponding belongs to MBMS list, if, illustrate that the MBMS in MBMS list is open-minded in Target cell, judge to preserve service resources configuration information in cell-of-origin, then enter step 210, otherwise, judge not preserve service resources configuration information in cell-of-origin, enter step 206.
Cell-of-origin is not positioned to the situation of MBSFN zone boundary, the MBMS (MBMS namely opened) sent due to all communities in a MBSFN region is identical, therefore, cell-of-origin directly can judge self to preserve UE in Target cell needs the resource allocation information of the MBMS received, and enters step 210.
Step 206, when not preserving service resources configuration information in cell-of-origin, cell-of-origin sends handover request message to Target cell, mainly comprises the MBMS list that UE reports, enter step 207 afterwards in message content.
Step 207 ~ 208, after Target cell receives handover request message, read MBMS list wherein, and judge that whether the MBMS belonging to MBMS list in this community is open-minded, if not, then after opening at once, enter step 209; If so, then directly step 209 is entered.
MBMS is not yet opened and UE first time situation about opening for this reason, if the eNB of Target cell does not add multicast group originally, then could open MBMS for the first time after also needing that this eNB is added multicast group.
Step 209, Target cell returns switching response message to cell-of-origin, carries service resources configuration information.
The situation Target cell opened by the MBMS in MBMS list is carried (such as in switching response message, UE wishes that the MBMS received was opened originally, or UE is open-minded for the first time for this reason), and the configuration information of the MBMS that UE needs in the configuration information, the i.e. Target cell that belong to the MBMS of MBMS list in Target cell are received, be also carried in switching response message.
Step 210, cell-of-origin, by the configuration information of Target cell, sends to UE by special RRC signaling.
Now, configuration information comprises service resources configuration information and Target cell ID.
Step 211, after receiving the configuration information of Target cell, the UE being in connected state carries out cell merge flow process, moves to Target cell, and utilizes the service resources configuration information in the configuration information obtained in cell-of-origin to start to receive MBMS in Target cell.
Afterwards, Target cell can also notify that UE release is connected with the RRC of cell-of-origin, and this flow process terminates.
Can find, embodiment once technical scheme can make the UE of connected state before target approach community, obtain configuration information, particularly the service resources configuration information of Target cell, then behind target approach community, directly can receive MBMS according to the service resources configuration information obtained from cell-of-origin, thus achieve the continuity of UE maintenance MBMS.
Embodiment two is the methods realizing MBMS service continuity for the UE of Idle state, and idiographic flow as shown in Figure 3, comprising:
Step 301, cell-of-origin periodically sends a request message to the UE of this community, and request UE reports MBMS list.
The process of this step, with step 201, repeats no more herein.
Step 302, after receiving request message, the UE being in Idle state judges that whether self is positioned at MBSFN zone boundary, if so, then enters step 303, otherwise enters step 305.
The process of this step, with step 202, repeats no more herein.
Step 303, UE initiates the request of RRC connection establishment to cell-of-origin, request is set up and is connected with the RRC of cell-of-origin.
Step 304, after the RRC connection establishment of cell-of-origin, UE reports MBMS list by measurement report or RRC signaling or MACCE message to cell-of-origin.
The process of this step, with step 203, repeats no more herein.
Step 305, select target community.
The process of this step, with step 204, repeats no more herein.
Step 306, judges the service resources configuration information whether preserving Target cell in cell-of-origin, if so, then enters step 307; If not, step 309 is entered.
The process of this step, with step 205, repeats no more herein.
It is pointed out that in step 302, if it is determined that UE is positioned at zone boundary, then in step 306, cell-of-origin may store service resources configuration information, also may not store; When judging in step 302 that UE is not positioned at zone boundary, then in step 306, cell-of-origin necessarily stores service resources configuration information, because when UE is not positioned at MBSFN zone boundary, a Target cell is directly selected in cell-of-origin from the MBSFN adjacent cell list self preserved, MBSFN community in MBSFN adjacent cell list and cell-of-origin belong to a MBSFN region, and the MBMS (MBMS namely opened) sent in these MBSFN communities is identical.
If UE is not in MBSFN zone boundary, then UE is in RRCIdle state (Idle state), otherwise UE is in RRCConnected state (connected state).
Step 307, before moving to Target cell, be connected if UE and cell-of-origin establish RRC, namely UE is in connected state, then cell-of-origin sends RRC connection release message to UE, notice UE release be connected with the RRC of cell-of-origin, now UE transfer Idle state to by connected state, carry the configuration information of Target cell in this message;
If when UE and cell-of-origin do not set up that RRC is connected, namely UE is in Idle state, the configuration information of Target cell is sent to UE by cell-of-origin, enters step 308.
In this step, configuration information comprises Target cell ID and service resources configuration information.
Step 308, the UE being in Idle state carries out cell reselection process according to the configuration information of Target cell, move to Target cell, and utilize the service resources configuration information in the configuration information of the Target cell obtained in cell-of-origin to start to receive MBMS in Target cell, this flow process terminates.
It is to be noted: for Idle state UE, if can not enter connected state, then UE carries out cell reselection, can be co-frequency cell gravity treatment, or alien-frequency district gravity treatment, and for alien frequencies gravity treatment, UE prioritizing selection MBSFN adjacent cell is as Target cell.
Step 309, when not preserving service resources configuration information in cell-of-origin, cell-of-origin sends handover request message to Target cell, comprises the MBMS list that UE reports in message content.
Step 310 ~ 311, after Target cell receives handover request message, read MBMS list wherein, and judge that whether the MBMS belonging to MBMS list in this community is open-minded, if not, then after opening at once, enter step 312; If so, then directly step 312 is entered.
MBMS is not yet opened and UE first time situation about opening for this reason, if the eNB of Target cell does not add multicast group originally, then could open after also needing that this eNB is added multicast group.
Step 312, Target cell sends switching response message to cell-of-origin, enters step 311 afterwards.
The situation that Target cell is opened the MBMS in MBMS list is carried in switching response message, and the configuration information (service resources configuration information) of the MBMS that UE needs in the resource allocation information, the i.e. Target cell that belong to the MBMS of MBMS list in Target cell are received, be also contained in switching response message.
Step 313, cell-of-origin, by the configuration information of Target cell, sends to the UE being in connected state by special RRC signaling.
In this step, configuration information comprises Target cell ID and service resources configuration information.
Step 314, the UE being in connected state carries out cell merge flow process according to configuration information, moves to Target cell, and utilizes the service resources configuration information in the configuration information of the Target cell obtained in cell-of-origin to start to receive MBMS.
Step 315, Target cell notice UE release is connected with the RRC of cell-of-origin, and this flow process terminates.
Can find, embodiment two technical scheme can make the UE of Idle state before target approach community, just obtain configuration information, particularly service resources configuration information, thus achieves the continuity of UE maintenance MBMS.
Embodiment three is the methods realizing MBMS service continuity for the UE of Idle state, and in this embodiment, UE does not enter connected state, but carries out cell reselection process, and idiographic flow as shown in Figure 4, comprising:
Step 401, when UE is in MBSFN zone boundary, UE judges whether the adjacent cell of cell-of-origin has MBSFN community, if so, enters step 402; If not, step 408 is entered.
If the adjacent cell of cell-of-origin has MBSFN community, then this adjacent MBSFN community is the MBSFN adjacent cell of cell-of-origin.
Step 402, UE reads the MCCH information of all MBSFN adjacent cells of cell-of-origin.
It is to be noted: if UE can not read adjacent cell MCCH information, and Idle state UE can not enter connected state, then UE prioritizing selection MBSFN adjacent cell is as Target cell.
Step 403, UE judges the resource allocation information of the MBMS whether having UE receiving in the MCCH information of MBSFN adjacent cell, if so, then enters step 404; If not, then step 406 is entered.
Step 404, when the resource allocation information of the MBMS having UE receiving in the MCCH information of MBSFN adjacent cell, i.e. service resources configuration information, service resources configuration information then in UE store M BSFN adjacent cell, then, UE selects a Target cell (this community is MBSFN community and has opened the MBMS that UE is receiving) according to the MCCH information of cell reselection criterion and MBMS adjacent cell from the MBSFN adjacent cell of cell-of-origin, then enters step 405.
Concrete, UE can confirm the configuration information having the MBMS having UE receiving in which MBSFN adjacent cell according to the MCCH information of MBMS adjacent cell, and from these MBSFN adjacent cells, selects a Target cell according to cell reselection criterion.
Step 405, UE carries out cell re-selection procedure according to the configuration information of the Target cell obtained in cell-of-origin, move to the Target cell chosen in step 404, in Target cell, then utilize the service resources configuration information obtained in cell-of-origin to start to receive MBMS, this flow process terminates.
As can be seen here, in this step, the UE of Idle state just obtained configuration information, particularly the service resources configuration information of Target cell before moving to Target cell, therefore, directly can receive MBMS according to service resources configuration information in Target cell, ensure that the continuity of MBMS.
Cell re-selection procedure is that for alien frequencies gravity treatment, UE prioritizing selection MBSFN adjacent cell is as Target cell with gravity treatment frequently or alien frequencies gravity treatment.
Step 406, during the configuration information of the MBMS not having UE receiving in the MCCH information of MBSFN adjacent cell, UE selects a Target cell (this community is MBSFN community but does not open the MBMS that UE receiving) according to cell reselection criterion, then turns to step 407.In this step, the configuration information of the Target cell that UE obtains comprises Target cell ID.
Step 407, UE carries out cell re-selection procedure, UE moves to the Target cell chosen in step 406, because this Target cell is MBSFN community, but do not open the MBMS that UE is receiving, then UE sends modify request messages to Target cell, and the content of message comprises MBMS list (MBMS wherein comprised is the MBMS that UE needs receive); After Target cell receives modify request messages, open MBMS, then UE gets resource allocation information, i.e. the service resources configuration information of MBMS, and start to receive MBMS, this flow process terminates.
As can be seen here, UE obtains service resources configuration information again after moving to Target cell, starts to receive MBMS, ensure that the continuity of MBMS equally.
Step 408, when the UE being arranged in MBSFN zone boundary judges that the adjacent cell of cell-of-origin does not have a MBSFN community, UE selects a Target cell according to cell reselection criterion, adjacent cell due to cell-of-origin does not have MBSFN community, therefore Target cell is not MBSFN community, then behind UE target approach community, service disconnection, this flow process terminates.
