Description

The changing method of the motion management method of MBS and the MBS of terminal

The application to application number is: 200910005256.0, the applying date is: on 01 21st, 2009, denomination of invention was the dividing an application of original application of the changing method > > of the motion management method of < < MBS and the MBS of terminal.

Technical field

The present invention relates to the communications field, and especially, relate to the changing method of the motion management method of a kind of multicast broadcast service (Multicast Broadcast Service, referred to as MBS) and the multicast broadcast service of terminal.

Background technology

At micro-wave access to global intercommunication (Worldwide Interoperability for Microwave Access, referred to as WiMAX) defined multicast broadcast service in system, multicast broadcast service is divided into two types, that is, and and broadcast/static multicast and dynamic multicast.Wherein, the carrying of the Access Network of broadcast or static multicast and airlink are set up in whole broadcast service region or multicast services region simultaneously, and do not consider under coverage whether certain base station has user at receiving multicast and broadcast service; Dynamic multicast is to only have while having user's receiving multicast and broadcast service under certain base station in multicast and broadcast coverage, just can set up Access Network carrying and the airlink relevant to this base station.

In actual applications, no matter adopt the multicast broadcast service of broadcast/static multicast or adopt the multicast broadcast service of dynamic multicast, when terminal moves in multicast broadcast service region, all need to guarantee that terminal can receiving multicast and broadcast service, this needs mutually to have coordinated between each network element of network side, that is, complete the handling process of switching.

Although defined the Access Network handoff procedure of clean culture in WiMAX system, this handoff procedure can not well be applicable to multicast broadcast service.And switch for the Access Network of multicast broadcast service, effective solution is not yet proposed at present.

In addition,, in current WiMAX technology, there are two kinds of business, that is, unicast service and multicast service, in actual applications, no matter be unicast service or multicast service, all have the possibility of switching, and this handoff technique need to obtain the support of air interface and the support of network side.In current WiMAX technology, unicast service to be switched, air interface and network side support are comparatively perfect, but for multicast, except air interface can be supported, lack supporting network side and support scheme.

The multicast broadcast service defining in WiMAX at present is mainly divided into two types, that is, and and broadcast/static multicast and dynamic multicast.Wherein, the Access Network of broadcast/static multicast carrying and airlink all in whole broadcast service region or multicast services region set up simultaneously, and not under consideration of regional certain base station whether have user at receiving multicast and broadcast service; And for dynamic multicast, the in the situation that of only having user's receiving multicast and broadcast service under certain base station in multicast and broadcast coverage, just can set up Access Network carrying and the airlink relevant to this base station.

In addition, WiMAX has defined multicast and broadcast transmission region (MBS Transmission Zone) and multicast and broadcast region (MBS Zone) two concepts.In MBS Zone, all base stations adopt same set of air interface parameters, and (MCIDs (LCIDs), SAIDs), for transmitting identical MBS business, terminal can utilize these air interface parameters to carry out receiving multicast and broadcast service.MBS Transmission Zone may comprise a plurality of MBS Zone, these air interface parameters may partly or entirely change, therefore,, if need terminal to receive identical MBS business at different MBS Zone, may adopt different air interface parameters.

When terminal moves to another one MBS Zone when (being called Target MBS Zone or New MBS Zone) from a MBS Zone (being called Serving MBS Zone or Current MBS Zone), if terminal expectation keeps the continuity of MBS business, be MS need to obtain current MBS Zone air interface parameters in value corresponding to target MBS Zone, terminal could continue receiving multicast and broadcast service at Targets MBS Zone so.

Conventionally, switching can be divided into two stages, that is, and and handoff preparation phase and handover execution stage, before the selected candidate base station of terminal is as the target BS switching, this terminal and network side base station mutual and network side is inner all belongs to alternately handoff preparation phase; The selected candidate base station of terminal is as the mutual of the terminal after target BS and network side base station and network side is inner all belongs to alternately handover execution stage.In handover execution stage, if terminal is switched to a candidate base station not belonging in handoff preparation phase, belong to uncontrolled switching/unpredictable switching.

For the support that unicast service is switched is provided, each BS safeguards the information of neighbor base station around, and the information spinner of these adjacent base stations is wanted to comprise: the MBS Zone ID under adjoining base station sign, adjoining base station physical parameter, adjoining base station.For supporting the switching of MBS business, the BS in MBS Zone can increase the following information of safeguarding: the multicast broadcast service stream information that this MBS Zone supports; Adjacent with this MBS Zone and support same MBS business in abutting connection with MBS Zone list.

For unicast service, switch, each serving BS is safeguarded the information that the unicast service of the MS of its service flows; For the switching of group business stream, each serving BS need to increase the multicast service stream information of safeguarding that each terminal receives.

Like this, for MBS is switched and provided support, the multicast service stream information that terminal need to be received is transferred to target BS.But to same multicast broadcast service, the traffic stream identifier (MSID, SFID) of each terminal maintenance may be not identical, therefore, the switching flow of unicast service stream can not solve the switching problem of multicast service.At present, for terminal, in the situation that different MBS Zone switches, how by overall identification, represent that multicast broadcast service and How to choose support the target BS of multicast broadcast service, not yet propose at present effective solution.

Embodiment

Functional overview

The present invention, by having redefined the mutual and network side base station of network side and terminal and MBS agency's reciprocal process, has realized the switching of Access Network in the situation that of broadcast or static multicast business, has reached the object of mobile management.

At WiMAX, multicast and broadcast transmission region (MBS Transmission Zone) and multicast and broadcast region (MBS Zone) two concepts have been defined.All base stations in MBS Zone adopt a set of identical air interface parameters, and (comprise MCIDs (LCIDs) and/or SAIDs) be used for transmitting identical multicast broadcast service (MBS business), terminal can be carried out receiving multicast and broadcast service by these air interface parameters.

A MBS Transmission Zone may comprise a plurality of MBS Zone, and between the different MBS Zone of same MBS Transmission Zone, these air interface parameters may partly or entirely change.Therefore,, when terminal receives identical MBS business at different MBS Zone, may adopt different air interface parameters; When terminal moves to another one MBS Zone when (being called target MBS region (Target MBS Zone) or new MBS region (New MBS Zone)) from a MBS Zone (being called service MBS region (Serving MBS Zone) or current MBS region (Current MBS Zone)), need to obtain the air interface parameters of current MBS Zone in value corresponding to target MBS Zone, terminal could continue receiving multicast and broadcast service by Target MBS Zone like this.

Each MBS Zone has corresponding MBS agency's (MBS Proxy), grappling MBS data channel (Anchor MBS DP) and a MBS isochronous controller (MBS Sync Controller), and different MBS Zone can share a MBS Proxy, Anchor MBS DP and MBS Sync Controller in same MBS Transmission Zone.

MBS agency (MBS Proxy) is in charge of and safeguards the MBS region parameter (MBS Zone Parameter) of each MBS Zone, MBS Zone Parameter comprise in following parameter information one of at least: MBS Zone ID, multicast broadcast service sign, multicast broadcast service stream information, MBS Proxy ID, MBS Sync Controller ID, Anchor MBS DP ID, MBS Service Policy etc.; And multicast broadcast service stream information comprise following parameter one of at least: multicast broadcast service traffic identifier MSFIDs, air interface parameters (comprising MCIDs, LCIDs), security association sign SAIDs, the grader of multicast broadcast service stream.

Wherein, multicast broadcast service sign can adopt one of at least following expression: multicast broadcast service mark (MBS Service ID), multicast and broadcast service program mark (MCBCS Program ID), multicast broadcast service channel labelling (MCBCS Channel ID), multicast broadcast service multicast and broadcast IP address (Broadcast or Multicast IP Address), multicast broadcast service multicast and broadcast IP address and port numbers (Broadcast and Multicast IP/Port Number), multicast broadcast service traffic identifier etc. identifies.

MBS Sync Controller is responsible for grand diversity or frame synchronization realization in MBS Zone; And the frame synchronization between MBS Zone realizes;

Anchor MBS DP can the packet of receiving from CSN (Core Service Network, core net) be sent in MBS Zone by data channel or MBS Transmission Zone in base station.

To describe the present invention in detail based on above-mentioned network configuration below.

Embodiments of the invention provide a kind of mobility management systems of multicast broadcast service, comprise that the affiliated target MBS of service MBS agency (Serving MBS Proxy), TBS under serving BS (SBS), target BS (TBS), SBS acts on behalf of (Target MBS Proxy).

In the following description, switching is divided into two stages, that is, and handoff preparation phase and handover execution stage; When the selected candidate base station of terminal is as the mutual of the terminal before the TBS switching and network side base station and network side is inner all belongs to alternately handoff preparation phase; The selected candidate base station of terminal is as the mutual of the terminal after TBS and network side base station and network side is inner all belongs to alternately handover execution stage.And in handover execution stage, if terminal is switched to a candidate base station not belonging in handoff preparation phase, belong to uncontrolled switching.To, based on above-mentioned network configuration, describe in detail according to the motion management method of the multicast broadcast service of the embodiment of the present invention below.

Wherein, serving BS, for carrying out alternately with Serving MBS Proxy, can continue the target BS list of the multicast broadcast service of the current transmission of support terminal and notify to terminal;

Afterwards, at selected certain the candidate TBS of terminal, during as final TBS, this TBS notification terminal continues and receives the parameter required with multicast broadcast service in target MBS region.

Serving BS knows that the process of candidate base station is: the target BS list that terminal will be switched to serving base stations report; Or the list of the target BS that one of at least selecting the following information that serving BS obtains from terminal or adjacent base station in advance according to itself will be switched: the load of neighbor base station radio environment information, serving BS and neighbor base station.

Particularly, in the situation that Serving MBS Proxy and Target MBS Proxy are different MBS Proxy, whether Serving MBS Proxy is for receiving the handover request message from SBS, check in the list of TBS and (TBS can belong to a plurality of Target MBS Zone) in the Target MBS Zone under TBS to have the Target MBS Zone that belongs to same MCBCS Transmission Zone with Serving MBS Zone to exist; If existed, show that terminal is switched to this TBS and can continues to receive same MBS business, Serving MBS Proxy searches the corresponding Target MBS of this Target MBS Zone Proxy, and send and carry the MBS Zone Parameter update request message of serving MBS Zone Parameter to Target MBS Proxy, wherein, in handover request message, carry terminal at the MBS Zone of Serving MBS Zone Parameters;

Target MBS Proxy, according to the MBS Zone Parameters in Serving MBS Zone, obtains this multicast broadcast service at MBS Zone Parameters corresponding to Target MBS Zone.

By MBS Zone Parameters Update Rsp message, the multicast broadcast service of the current reception of terminal, the corresponding relation band between Target MBS Zone and Serving MBS Zone sends to Serving MBS Proxy to Target MBS Proxy; Serving MBS Proxy is issuing SBS by HO RSP message by this corresponding relation;

SBS selects the station list notification terminal that can continue support terminal MBS business; SBS also can bring terminal the relation between MBS Zone Parameters parameter between the Target MBS Zone under each TBS and current Serving MBS Zone;

If SBS only need to select, can continue the station list (station list that does not belong to current Serving MBS Zone) of support terminal MBS business and not need the relation between MBS Zone Parameters parameter between the Target MBS Zone under each TBS and current Serving MBS Zone to bring terminal, the process that does not need the relation between the MBS Zone Parameters between Serving MBS Zone and Target MBS Zone for the MBS business obtaining current terminal and receive of interacting message between above-mentioned Serving MBS Proxy and Target MBS Proxy, does not need by these relations, to bring serving BS by message yet.

Serving MBS Proxy searches each TBS receiving in TBS list, in one or more Target MBS Zone under judgement TBS, whether having the affiliated Serving MBS Zone of a Target MBSZone and current terminal place SBS is same Transmission Zone, or the identical MBS business of no transmission; If the judgment is Yes, show that terminal is switched to after this TBS, can the Target MBS Zone under TBS continue and receive former MBS business, and Serving MBS Proxy thinks that this TBS is for can continue the base station that support terminal receives identical multicast broadcast service.And by after definite station list is returned to SBS.

After terminal has been selected the target BS of certain switching, the corresponding relation of multicast broadcast service MBS Zone Parameters between Serving MBS Zone and MBS Zone that this target BS meeting terminal receives is notified to terminal.If target BS is current, there is no MBS business that terminal the receives corresponding relation between the MBS Zone Parameters between Serving MBS Zone and Target MBS Zone, TBS need to first obtain this corresponding relation.

If controlled switching, during TBS that terminal notice SBS chooses, the target BS that SBS notice Serving MBS Proxy switches, Serving MBS Proxy can send message to the Target MBS Proxy under target BS, receives the MBS Zone Parameters of MBS business in message with current terminal at Serving MBS Zone; Target MBS Proxy receives after message, the corresponding relation notice TBS of the MBS business that current terminal can be received between the MBS Zone Parameters between Serving MBS Zone and Target MBS Zone;

If uncontrolled switching, the TBS that terminal is switched to is not in handoff preparation phase in the candidate base station list of serving BS notification terminal; The process of uncontrolled switching is: the terminal of switching can be initiated distance measurement request message to TBS, wherein, in this distance measurement request message with the sign of SBS; TBS notification terminal is in the continuous required parameter of receiving multicast and broadcast service of target MBS region relaying; Terminal is carried out the reception of multicast broadcast service according to this parameter.

In uncontrolled switching, when TBS receives that after the distance measurement request message that SBS identifies in addition, TBS and SBS carry out interacting message, obtain the MBS Zone Parameters that current terminal receives MBS business; If SBS can not provide in required MBS Zone Parameters parameter partly or entirely, SBS can be by obtaining with Serving MBS Proxy alternately; Or TBS continues and Serving MBS Proxy obtains the partial parameters in the MBS Zone Parameters of the terminal reception MBS business that SBS can not provide alternately.

In uncontrolled switching, TBS has obtained current terminal and has received MBS business after the MBS Zone of Serving MBS Zone Parameters, also needs to obtain current terminal and receives MBS business MBS Zone Parameters corresponding relation between Serving MBS Zone and Target MBS Zone.TBS can continue and Target MBS Proxy carries out interacting message and obtains current terminal and receive MBS business MBS Zone Parameters corresponding relation between Serving MBS Zone and Target MBS Zone; Or above-mentioned, from SBS or/and Serving MBS Proxy obtains current terminal, receive MBS business at the MBS Zone of Serving MBS Zone Parameters simultaneously, also obtain current terminal simultaneously and receive MBS business MBS Zone Parameters corresponding relation between Serving MBS Zone and Target MBS Zone.

In addition, also having a kind of situation is exactly that SBS and TBS belong to same MBS Proxy jointly.In this case, the interacting message between aforementioned all Serving MBS Proxy and Target MBS Proxy does not exist, and they both are same functive.

Below in conjunction with concrete condition, describe processing procedure of the present invention in detail.

Situation one: SBS belongs to Serving MBS Proxy, TBS and belongs to Target MBS Proxy.

As shown in Figure 1, in this case, according to the motion management method of the multicast broadcast service of the embodiment of the present invention, comprise:

Step S102, after SBS under terminal (MS) meets predetermined switching condition and MS is known the candidate base station of switching, SBS sends handover request message to Serving MBS Proxy, carries the MBS Zone Parameter that the list of TBS outside the Serving MBS Zone that is positioned at Serving MBS Proxy place in candidate base station and the MBS context of MS are preserved in handover request message;

Step S104, Serving MBS Proxy receives after handover request message, in Target MBS Zone in the list of inspection TBS under TBS, whether support the multicast broadcast service (TBS can belong to a plurality of MBS Zone) of the current transmission of MS, if supported, determine the corresponding Target MBS of this Target MBS Zone Proxy, and send the MBS Zone Parameter update request message of carrying Serving MBS Zone parameter to Target MBS Proxy;

Step S106, the multicast broadcast service that Target MBS Proxy receives terminal returns to Serving MBS Proxy at MBS Zone Parameters corresponding to Target MBS Zone by MBS Zone Parameters Update RSP;

Step S108, Serving MBS Proxy supports current set of terminal multicast broadcasting service situation to return to SBS by switching response message HO RSP TBS;

Step S110, SBS notifies the TBS list that can continue the current multicast broadcast service of terminal to terminal (by message MOB BSHO REQ/RSP);

Step S112, after certain TBS in terminal notice SBS station list is selected, message transfer between SBS, Serving MBS Zone Proxy, Target MBS Proxy and TBS, the TBS choosing can obtain the corresponding relation of the current receiving multicast and broadcast service of terminal MBS Zone Parameter between Serving MBS Zone and Target MBS Zone;

Step 114, when terminal is switched on TBS, TBS is the corresponding relation notification terminal of the current receiving multicast and broadcast service of terminal MBS Zone Parameter between Serving MBS Zone and Target MBS Zone.

In addition, above-mentioned steps S108 can also be, Serving MBS Proxy carries out base station selected according to its local policy, and by selection result through SBS notification terminal;

Fig. 2 shows the signaling process that handoff preparation phase is processed in the situation that being initiated to switch by end side, as shown in Figure 2, specifically comprises the following steps:

(21) MS sends MOB MSHO REQ message to SBS, in message with the list of TBS;

(22) SBS sends HO REQ message to Serving MBS Proxy, in message, with TBS list and MS receiving multicast and broadcast service, identifies; Optionally, can be with the MBS Zone Parameter of upper current MBS Zone;

(23) Serving MBS Proxy sends MBS Zone Parameter Update REQ message to Target MBS Proxy, in message, with TBS list and MS receiving multicast and broadcast service, identifies; Optionally, can be with the MBS Zone Parameter of upper current MBS Zone;

(24) Target MBS Proxy sends MBS Zone Parameter Update RSP message to Serving MBS Proxy, TBS list and the mark of whether supporting original multicast broadcast service sign on message band; Optionally, if TBS supports the multicast broadcast service of the current reception of MS, can be with upper same multicast broadcasting service at the corresponding relation between MBS Zone Parameter between Target MBS Zone and Serving MBS Zone;

(25) Serving MBS Proxy sends HO RSP message to SBS, TBS list and the mark of whether supporting original multicast broadcast service sign on message band; Wherein but TBS list Serving MBS Proxy screens according to local policy; Optionally, if TBS supports the multicast broadcast service of the current reception of MS, can be with upper same multicast broadcasting service at the corresponding relation between MBS Zone Parameter between Target MBS Zone and Serving MBS Zone;

(26) SBS sends MOB BSHO RSP message to MS, and in message, with TBS list, wherein TBS list can be that SBS screens according to local policy.

Alternatively, can in this MOB BSHO RSP message, carry same multicast broadcasting service between Target MBS Zone and Serving MBS Zone in MBS Zone Parameter the corresponding relation between air interface parameters (being MCID, LCIDs, SAs) be another one inventive point.So just can save the treatment step that handover execution stage is carried out this corresponding relation notice.

Fig. 3 shows the signaling process that handoff preparation phase is processed in the situation that being initiated to switch by network side, as shown in Figure 3, specifically comprises the following steps:

Step S1102, TBS sends context request message to SBS;

Step S1104, SBS sends to TBS by context request response message by the multicast broadcast service stream information of the multicast broadcast service of the current reception of terminal.The multicast broadcast service stream information of terminal can comprise following one of at least: traffic stream identifier, multicast and broadcast area identification, multicast and broadcast transmission region sign, grouped data traffic identifier, business continuance require indication, multicast and broadcast connection identifier.Like this, in multicast broadcast service stream information, just can, using multicast and broadcast transmission region sign as the first sign, using grouped data traffic identifier as the second sign, utilize the first sign and/or the second mark for marking or index-group multicast broadcasting service stream.Thereby reached the object that identifies uniquely a multicast broadcast service in global scope.

A kind of changing method of multicast broadcast service of terminal is provided according to a further aspect in the invention.

In order to realize the switching of multicast broadcast service, first need to solve the identified problems of multicast broadcast service.In correlation technique, multicast service stream attribute can be reused the attribute of unicast service stream, still, due to unicast service traffic identifier (SF ID), Shi YiMSWei unit distributes, and that is to say, unicast service is flowed, (MS ID, SF ID) can flow by unique identification unicast service; And to certain multicast service, when MS subscribes to certain group business stream, its grappling service flow authorization device (Anchor SFA) that is positioned at Access Network also can distribute a traffic stream identifier SF ID for this MS, now, for same group business stream, each MS that receives this business can have a corresponding combination (MS ID, SF ID) to identify this group business stream.Obviously, to group business stream, the identification method of unicast service can not be unified the sign of mode in global scope to multicast service, can not reach the object of sign multicast service.

With regard to unicast service stream, one of all traffic flow assignment that core net can be subscribed to for MS grouped data traffic identifier within the scope of this MS (can be described as PDF ID, this sign is corresponding one by one with the SF ID in Access Network), so just can carry out unicast service stream of unique identification with (MS ID, PDFID); In Access Network, (MS ID, PDFID) can be mapped to (MS ID, SF ID), in like manner, also can carry out unicast service stream of unique identification with (MS ID, SFID);

For multicast service, core net can be in multicast and broadcast transmission region, (this region can identify with MCBCS Transmission Zone ID,, the first sign of hereinafter describing) (the group business stream of carrying distributes a unique sign PDF ID in this multicast and broadcast region, the second sign of hereinafter describing), so just can carry out group business stream of unique identification with (MCBCS Transmission Zone ID, PDF ID).Now, uniquely identified group business stream (MCBCS Transmission ID, PDFID) can be mapped to a plurality of (MS ID, SFID) in Access Network.

Based on above-mentioned identification method, will describe according to the changing method processing procedure of the multicast broadcast service of terminal of the present invention below.

In the changing method that will describe below, handoff procedure does not need the participation of MBS Proxy, and each BS preserves multicast broadcast service stream parameter and the air interface parameters thereof of the current receiving multicast and broadcast service stream information of terminal, this BS place MBS Zone and the multicast and broadcast zone list of supporting same multicast broadcast service.

Like this, the multicast broadcast service stream parameter that just can terminal be received by serving BS is delivered to target BS, then the multicast broadcast service air interface parameters MCID that target BS is corresponding etc. sends to terminal, thereby terminal can continue receiving multicast and broadcast service in new multicast and broadcast region.

In addition, this method needs the overall identification of multicast broadcast service, the overall identification of multicast broadcast service can adopt multicast and broadcast transmission region sign to be added in the grouped data traffic identifier for this multicast broadcast service distribution in multicast and broadcast transmission region to represent (that is, above-mentioned identification method).

A kind of changing method of multicast broadcast service of terminal is provided in embodiments of the present invention.

As shown in figure 12, according to the changing method of the multicast broadcast service of the terminal of the embodiment of the present invention, comprise step S1202 and step S1204.

Being specifically treated to shown in Figure 12:

Step S1202, the serving BS of terminal is preserved the multicast broadcast service stream information that terminal receives;

Step S1204, serving BS passes to the multicast broadcast service stream information of terminal by message the target BS of switching.

Multicast broadcast service stream information comprise following one of at least: traffic stream identifier (SF ID), multicast and broadcast area identification (MBS Zone ID), multicast and broadcast transmission region sign (MBS Transmission Zone ID), grouped data traffic identifier (PDF ID), business continuance require indication (serving BS can determine whether the broadcasting multicast service of switching have requirement to continuity according to this sign), multicast and broadcast connection identifier (MCID).

Preferably, can be using the multicast and broadcast transmission region sign in multicast broadcast service stream as the first sign, using the grouped data traffic identifier in multicast broadcast service stream as the second sign, and in multicast broadcast service stream information, identify multicast broadcast service by the first sign and/or the second mark for marking.

In multicast broadcast service stream information, traffic stream identifier is unique within the scope of terminal, therefore in certain terminal, can flow with certain multicast broadcast service that traffic stream identifier identifies or this terminal of index receives.In addition, the unique distribution in multicast and broadcast transmission region of grouped data traffic identifier in multicast broadcast service information flow, therefore can be using the multicast and broadcast transmission region in multicast broadcast service stream as above-mentioned the first sign, and using the grouped data traffic identifier in multicast broadcast service stream information as above-mentioned the second sign, network side just can identify and/or the second mark for marking or this multicast broadcast service stream of index with first like this.

In addition, in the situation that the target BS switching and the serving BS of terminal belong to different multicast and broadcasts region, at target BS, receive after the multicast broadcast service stream information from serving BS, target can determine that according to multicast broadcast service stream information terminal is in the continuous required parameter of receiving multicast and broadcast service of target multicast and broadcast region relaying in base station, and parameter is sent to terminal; Terminal is according to the parameter receiving multicast and broadcast service from target BS.

And, target BS send to the parameter of terminal can comprise following one of at least: other multicast broadcast service stream information parameter changing after traffic stream identifier, multicast and broadcast area identification, multicast and broadcast connection identifier, multicast and broadcast area change.

Particularly, the transmission of multicast broadcast service stream information can be carried out in the preparatory stage of controlled switching and the execution phase of switching, the different phase of describing switching in detail was carried out to the processing procedure of the notice of multicast broadcast service stream information below.

The preparatory stage transport multicast broadcasting service stream information that (situation one) switched

In this case, switching can be initiated by terminal, also can be initiated by network side.

On the one hand, in the situation that switching is initiated by terminal, serving BS notifies the processing to the target BS switching to comprise multicast broadcast service stream information:

The preparatory stage of switching, serving BS receives the handover request message of self terminal, and in the base station of carrying, select to support the base station of same multicast broadcast service as target BS, and by handover request message informing, give by multicast broadcast service stream information the target BS of selecting from handover request message.

And, in the situation that same multicast broadcast service is not all supported in the base station that serving BS judgement terminal is carried in sending to the handover request message of serving BS, serving BS can send switching response message to terminal, and in switching response message, carries the indication of this switching of refusal.Preferably, in this switching response message, may further include the successional base station of support multicast broadcast service that serving BS is recommended.

When MS while receiving multicast and broadcast service and unicast service, in the situation that multicast broadcast service is not all supported in the base station that serving BS judgement terminal is carried in sending to the handover request message of serving BS, serving BS need to determine whether to refuse current switching according to its local policy.For example, although all target BS same multicast broadcast service of the current reception of support terminal not, if target BS continues to support unicast service, and unicast service priority ratio is higher, for example, the type of unicast service is urgent call, and now serving BS can not be refused current switching.

In addition, particularly, the switching triggering for MS, the process that the handover request message that serving BS can send according to terminal judges the successional base station of multicast broadcast service that can the current reception of support terminal as shown in figure 13, specifically comprises following processing:

Step 1302, serving BS is received the handover request message that MS sends, and comprises the target BS list of switching in this message;

Step 1304, if need to support multicast and broadcast data service continuity, need to check the target BS list in handover request message, judge whether the successional base station of multicast broadcast service (that is, determining whether to exist target BS) that exists support terminal to receive; If existed, execution step 1306, otherwise execution step 1308;

Step 1306, to supporting the target BS of same multicast broadcast service to send handover request message, continues switching flow;

Step 1308, serving BS sends switching response message to MS, the switching that this response message is initiated for refusing MS, and the successional target BS of multicast broadcast service that serving BS can receive support terminal by this response message is recommended terminal.

On the other hand, in the situation that switching is initiated by network side, as shown in figure 14, serving BS notifies the processing to the target BS switching to comprise multicast broadcast service stream information:

Step 1402, the preparatory stage of switching, serving BS is from selecting to support the base station of this multicast broadcast service as target BS neighbor base station around, and the target BS that the multicast broadcast service stream information of terminal is selected to network side by handover request message informing;

Step 1404, serving BS is selected by handover request message informing the multicast broadcast service stream information of terminal target BS to network side (that is, the successional adjacent base station of the multicast broadcast service of the current reception of support terminal).

The execution phase transport multicast broadcasting service stream information that (situation two) switched

In this case, as shown in figure 15, serving BS notifies the processing to the target BS switching to comprise (terminal) multicast broadcast service stream information:

Step 1502, serving BS receives the switch indicating information of self terminal, obtains the final goal base station (final target BS is selected by terminal) of switching from switch indicating information;

Step 1504, serving BS is notified the multicast broadcast service stream information of terminal to target BS by switching authentic information.

In addition, in the situation that carry out switch to uncontrollable or unpredictable switching, serving BS notifies the processing to target BS to comprise the multicast broadcast service stream information of terminal: target BS sends context request message to serving BS; Serving BS is included in the multicast broadcast service stream information of terminal in context request response message and sends to target BS.

In addition, in the method, when target BS becomes after the new serving BS of terminal, the multicast broadcast service stream information of the terminal that new serving BS is preserved.

In sum, by means of technical scheme of the present invention, by the Signalling exchange between functional entity in the middle of define grid side and terminal and network side, and multicast broadcast service is identified uniquely, effectively realized the switching of the multicast broadcast service of terminal, avoided in correlation technique, the handover scheme of unicast technique being applied to the problem that multicast and broadcast switches and causes thus, filled up the blank of correlation technique.

The foregoing is only the preferred embodiments of the present invention, be not limited to the present invention, for a person skilled in the art, the present invention can have various modifications and variations.Within the spirit and principles in the present invention all, any modification of doing, be equal to replacement, improvement etc., within all should being included in protection scope of the present invention.
