Description

A kind of method, system and user equipment for realizing MBMS service continuity

Technical field

The present invention relates to long term evolution (LTE) technologies, particularly relate to a kind of realization multimedia broadcast multi-broadcasting business (MBMS) Successional method and system.

Background technology

With the fast development of Internet and popularizing for large screen Multi-featured Mobile Terminal, there are a large amount of mobile datas Multimedia service and various high bandwidth multimedia services, as video conference, television broadcasting, video on demand, advertisement, online education, Interactive game etc., this aspect meet the multiple services demand of mobile subscriber, are on the other hand also that mobile operator is brought newly Business growth point.The multiple users of these mobile data multimedia service requirements can receive identical data simultaneously, and general Data service is compared, and has the characteristics that data volume is big, the duration is long, delay sensitive.

In order to effectively utilize mobile network resource, third generation partner program (3GPP, 3rd GenerationPartnership Project) propose multimedia broadcast multi-broadcasting business (MBMS, Multimedia BroadcastMulticast Service).MBMS business is that one kind is transmitted from a data source to multiple destination mobile terminals The technology of data realizes the shared of network (including core net and access net) resource, it is (especially aerial to improve Internet resources Interface resource) utilization rate.The MBMS business that 3GPP is defined can not only realize the message class multicast of plain text low rate and wide It broadcasts, but also can realize broadcast and the multicast of high-speed multimedia service, a variety of abundant videos, audio and multimedia industry are provided Business, this has undoubtedly complied with the trend of the following mobile data development, better services foreground is provided for the development of 3G.

The user equipment (UE or terminal) for receiving MBMS business may be at one of following two states:One kind is RRC Connected state (RRC_CONNECTED, referred to as connected state);Another kind is RRC Idle state (RRC_IDLE, referred to as Idle state), It is studied only for the UE under Idle state in the present invention.Whether unicast service is being received according to UE, it can be determined that is being connect The UE for receiving MBMS business is to be in Idle state in connected state;When UE is when receiving unicast service, UE is in connected state;Place Wireless heterogeneous networks (RRC, Radio Resources Control) connection, place are not established with network side in the UE of Idle state Then RRC is established in the UE of connected state with network side to connect.

In the process of moving, for the UE of Idle state, generally enter Target cell using cell selection or re-selection procedure; For the UE of connected state, generally enter Target cell using cell switching flow.

If UE has the MBMS business received in cell-of-origin, after UE enters Target cell, UE will read broadcast control Channel (BCCH, Broadcast Control CHannel) processed and multicast control channel (MCCH, Multicast Control Channel message), to obtain the resource allocation information of MBMS business in Target cell.If Target cell belongs to cell-of-origin In the region identical MBMS Single Frequency Network (MBSFN, MBMS over a Single Frequency Network), i.e.,:Target Cell and cell-of-origin belong to this region MBSFN, and MBMS business is sent in Target cell, then UE is into target The resource allocation information of MBMS business may not necessarily be read after cell, directly use the MBMS business of cell-of-origin (current area) Resource allocation information can receive MBMS business in Target cell, realize the continuity of MBMS business;If Target cell and source Cell belongs to the different regions MBSFN, then UE needs to read the resource allocation information of MBMS business after entering Target cell;Such as Fruit UE in Target cell needs the MBMS business received not send, then UE can not read MBMS after entering Target cell The resource allocation information of business can not also receive MBMS business.

The reception state of UE with MBMS business ability includes:Receiving MBMS business and, reception MBMS interested Business.Reception MBMS business interested refers to that UE receives MBMS business not yet, and prepares to receive MBMS business, at this point, UE exists MBMS notification messages are monitored in the regions MBSFN, and MCCH message and MBMS data are further read according to MBMS notification messages. For the MBMS business of reception interested, if the MBMS business does not have started transmission, UE does not know the MBMS business generally With the correspondence in the regions MBSFN.

Operator can dispose multiple frequency points (frequency point refers to the centre frequency and bandwidth of frequency band), existing MBMS in a network Business is generally transmitted using MBSFN modes, therefore MBMS business is generally deployed on the frequency point that some is continuously covered, that is, is existed In the regions MBSFN, MBMS business is sent in determining frequency.

In the regions MBSFN, if receiving or it is interested receive MBMS business UE negligible amounts, may be used Point-to-point (PTP) mode sends MBMS business, and the side wireless access network (RAN) does not know that MBMS business passes through unicast transmission at this time.

Cell selects or gravity treatment belongs to the mobility under UE Idle state.Cell selects:Initial cell selection, from connection State returns to Idle state and reenters service.Cell selection includes that UE is searched in each RAT supported on each carrier frequency Strongest cell is until finding suitable cell.When leaving connection mode, the cell of the UE connections of generally selecting over still connects Connect the information that release message may include cell in instruction UE search specific frequencies;When UE has found in selected PLMN without suitable cell When, it executes " arbitrary cells search ", under this state, UE does not allow to receive MBMS business.

Cell selects or the purpose of gravity treatment is to ensure that Idle state UE is resided in best cell.In the wireless network, small Area selects or gravity treatment is a necessary process, and main cause is the mobility of UE and the fluctuation of wireless environment, is thus drawn Play the fluctuation of signal strength and interference level.In LTE, network side can be different excellent of different most 8 of set of frequency First grade, Idle state UE carries out cell selection or gravity treatment according to frequency priority sequence, and when frequency priority is identical, UE is according to wireless The sequence of channel quality carries out cell selection or gravity treatment.

As a basic principle, each terminal uses the wireless measurement itself completed, and (such as the beacon that is received is believed Road level) and the parameter (such as threshold value) that is provided of network and part system information cell selection or reselection criterion are commented Estimate.The multimode terminal in environment for providing a variety of access technologies, terminal are needed using from different usable frequencies and access Reselection criterion is assessed in the measurement of technology.

Parameter used in network-control reselection criterion, to allow, according to network needs, the UE in Idle state to be moved Move maximally related network layer.

Find that the prior art has the following problems in the research of the prior art and practice process:For Idle state UE, When it uses the cell selection of unicast or re-selection procedure selection target cell, the reception of MBMS business, selected target are not accounted for Cell possibly can not provide UE and receive or the MBMS business of reception interested, and MBMS can be caused after UE enters Target cell Business, which receives, interrupts so that the continuity that Idle state UE receives MBMS business cannot ensure well, while influence user's industry Business experience.

Illustrate the solution of the present invention below by specific embodiment.

Embodiment one

For the scene that Idle state UE is moved in the regions MBSFN, method such as Fig. 2 institutes of MBMS service continuity are realized Show, including:

Step 201, network side sends cell selection or the gravity treatment relevant configuration information of MBMS business.The cell of MBMS business Selection or gravity treatment relevant configuration information include:There is provided MBMS business frequency point information (refer to send MBMS business centre frequency and Bandwidth) and neighboring community (neighboring community for referring to cell-of-origin) MBSFN area identifications instruction and alien frequencies neighboring community frequency List and at least one of cell selection or reselecting parameters.

Wherein, the frequency point information of MBMS business, the list of frequency of alien frequencies neighboring community and cell selection or gravity treatment ginseng are provided Number is supplied to UE by network side by system message and RRC signaling;

The MBSFN area identifications instruction of neighboring community, including:MBSFN area identifications of neighboring community, and/or identical The regions MBSFN indicate information bit;

The MBSFN area identifications instruction of neighboring community can be through source eNB (eNB of cell-of-origin) and adjacent eNB (neighboring community ENB) between interaction and UE is supplied to by cell-of-origin (source eNB obtains neighboring community by X2 connections from adjacent eNB The MBSFN area identifications of acquisition are supplied to UE by MBSFN area identifications, cell-of-origin);Alternatively, being assisted according to multiple-unit/multicast Entity (MCE, Multi-cell/multicast Coordination Entity) instruction is adjusted (wherein to carry neighboring community MBSFN area identifications) UE (such situation does not have X2 connections between source eNB and adjacent eNB) is supplied to by cell-of-origin.

Cell selects or reselecting parameters include at least:Cell selects or gravity treatment threshold value, frequency priority and time parameter Deng.

Step 202, UE receives cell selection or gravity treatment relevant configuration information and the UE of the MBMS business of network side transmission When meeting specific search or measurement standard to the measurement result of cell-of-origin and neighboring community, UE determines to carry out cell selection or again Choosing.

Wherein it is determined that it is existing that UE meets specific search or measurement standard to the measurement result of cell-of-origin and neighboring community Technology, details are not described herein again.

If UE is not received by cell selection or the gravity treatment relevant configuration information of the MBMS business of network side transmission, or Person UE is unsatisfactory for specifically searching for or when measurement standard to the measurement result of cell-of-origin and neighboring community, without cell selection or Gravity treatment.

Step 203, the set of frequency that MBMS business is provided in cell-of-origin is highest priority, UE selections and the highest by UE Priority frequency belongs to neighboring community, the i.e. homogeneous frequency adjacent area of the cell-of-origin of same frequency layer.

In the step, UE is highest priority by the set of frequency of MBMS business is provided in cell-of-origin, does not consider network side The frequency priority of setting;Then, UE selects to belong to same frequency layer with the highest priority frequency from the neighboring community of cell-of-origin Cell, referred to as homogeneous frequency adjacent area.Subsequently, UE selection target cells from these homogeneous frequency adjacent areas.

Step 204, it is at least one to judge whether the homogeneous frequency adjacent area that can provide MBMS business has by UE, if so, turning to Step 205, step 211 is otherwise turned to.

UE can know in the homogeneous frequency adjacent area of cell-of-origin there is which cell according to the frequency point information for providing MBMS business MBMS business can be provided.

The essence of the step is to filter out the unicast cells of homogeneous frequency adjacent area, you can provides the homogeneous frequency adjacent of MBMS business Cell belongs to some region MBSFN.

Step 205, in it can provide the homogeneous frequency adjacent area of MBMS business, UE judges and cell-of-origin has identical MBSFN It is at least one whether the homogeneous frequency adjacent area of area identification has, if so, turning to step 206, otherwise turns to step 211;

Homogeneous frequency adjacent area of the so-called and cell-of-origin with identical MBSFN area identifications refers to:Although cell-of-origin and same frequency The MBSFN area identifications of neighboring community are not exactly the same, such as:The MBSFN area identifications of cell-of-origin are:MBSFN area ID1, MBSFN area ID2, MBSFN area ID3 }, there are the MBSFN area identifications of a homogeneous frequency adjacent area to be:{MBSFN area ID1, MBSFN area ID4, MBSFNarea ID5 }, but for the MBMS business that some UE is received, specifically:Work as UE Belong to MBSFN area ID1, then for the UE, cell-of-origin and homogeneous frequency adjacent area in the MBMS business that cell-of-origin receives MBSFN area identifications having the same.

In addition, when the UE MBMS business received in cell-of-origin belongs to MBSFN area ID2, then for the UE, source is small Area and homogeneous frequency adjacent area do not have identical MBSFN area identifications.

The cell selection of MBMS business or the MBSFN area identifications instruction of the neighboring community in gravity treatment relevant configuration information, Including:The MBSFN area identifications of neighboring community, and/or the identical regions MBSFN indicate information bit.

Wherein, the identical regions MBSFN instruction information bit refers to:Network side is that several adjacent co-frequency cells of cell-of-origin are matched An instruction information bit is set, indicates that homogeneous frequency adjacent area and the source are small preferably, can be arranged when the instruction information bit is 1 Area has identical MBSFN area identifications (to indicate that there are identical MBSFN area identifications in homogeneous frequency adjacent area and the cell-of-origin certainly It indicates that the setting of information bit can also have other modes, such as is set as 0).

For example, the MBSFN area identifications of cell-of-origin A are:{ MBSFN area ID1 ..., MBSFN areaID N } (N is big In equal to 1);The MBSFN area identifications of homogeneous frequency adjacent area B are:{ MBSFN areaID1 ..., MBSFN area ID N } (N More than or equal to 1);The MBSFN area identifications of homogeneous frequency adjacent area C are:{ MBSFN area ID1 ..., MBSFN area ID M } (M is more than or equal to N), it can be seen that, homogeneous frequency adjacent area B and C and cell-of-origin A MBSFN area identifications having the same, then The corresponding identical regions the MBSFN instruction information bit of homogeneous frequency adjacent area B and C is all set to 1.

That is:If the MBSFN area identifications of some homogeneous frequency adjacent area are equal to or the MBSFN comprising cell-of-origin When area identification, the identical regions MBSFN of homogeneous frequency adjacent area instruction information bit is just set as 1 by network side, is otherwise referred to Show that information bit is set to 0.

Step 206, MBMS business will can be provided and have the homogeneous frequency adjacent of identical MBSFN area identifications small with cell-of-origin Area is ranked up.

If MBMS business can be provided and had with homogeneous frequency adjacent area of the cell-of-origin with identical MBSFN area identifications more It is a (more than one), then UE utilizes R criterion (R- according to the quality of wireless channel for measuring these obtained cells Criterion) these cells are ranked up, it is possible thereby to confirm the best homogeneous frequency adjacent area of quality of wireless channel.

Step 207, UE selection targets cell.

If MBMS business can be provided and with cell-of-origin there is the homogeneous frequency adjacent area of identical MBSFN area identifications to only have One, then UE is as Target cell;

If MBMS business can be provided and had with homogeneous frequency adjacent area of the cell-of-origin with identical MBSFN area identifications more It is a (more than one), then the homogeneous frequency adjacent area for selecting quality of wireless channel best is as Target cell.

Step 208, UE is moved to Target cell, service conditions of the UE in cell-of-origin is judged, if UE is at cell-of-origin In the state for receiving MBMS business, step 209 is turned to;If UE is in the shape interested for receiving MBMS business in cell-of-origin State turns to step 210.

Step 209, if UE is in the state for receiving MBMS business in cell-of-origin, after UE enters Target cell, because Belong to the identical regions MBSFN for cell-of-origin and Target cell, so UE can not have to first read MCCH information and continue to MBMS business, then MBMS business will not interrupt, realize business continuance.

Step 210, if UE is in the state interested for receiving MBMS business in cell-of-origin, after UE enters Target cell, UE continues to monitor MCCH notification informations, prepares to receive MBMS business.

Step 211, UE selection targets cell.

Step 204 is accepted, if there is no that the cell of MBMS business can be provided in homogeneous frequency adjacent area;Alternatively,

Step 205 is accepted, if identical there is no having with cell-of-origin during the homogeneous frequency adjacent area of MBMS business can be provided The cell of MBSFN area identifications;

So, UE selects to meet cell selection or the unrestricted access of gravity treatment threshold requirement from the neighboring community of cell-of-origin Cell is as Target cell.

Wherein, meet quality of wireless channel foundation S standards (S-criterion) operation that threshold requirement refers to Target cell Result afterwards meets cell selection or gravity treatment threshold value.

Unrestricted access cell refers to that the taboo that the cell is not belonging in blacklist selects cell.

Step 212, UE is moved to Target cell, and UE sends MBMS business to NAS or application layer by AS and interrupts instruction, and Illustrate interruption source (in the embodiment, MBMS business interruption is as caused by the three kinds of situations pointed out in step 211) to improve The business experience of user.

Embodiment two

For Idle state UE in the scene of the interregional movements of MBSFN, method such as Fig. 3 institutes of MBMS service continuity are realized Show, including:

Step 301, network side sends cell selection or the gravity treatment relevant configuration information of MBMS business.

The step is identical as step 201, and details are not described herein again.

Step 302, UE receives cell selection or gravity treatment relevant configuration information and the UE of the MBMS business of network side transmission When meeting specific search or measurement standard to the measurement result of cell-of-origin and neighboring community, UE determines to carry out cell selection or again Choosing.

The step is with step 202, and details are not described herein again.

Step 303, the set of frequency that MBMS business is provided in cell-of-origin is highest priority, UE selections and the highest by UE Priority frequency belongs to neighboring community, the i.e. homogeneous frequency adjacent area of the cell-of-origin of same frequency layer.

The step is with step 203, and details are not described herein again.

Step 304, it is at least one to judge whether the homogeneous frequency adjacent area that can provide MBMS business has by UE, if so, turning to Step 305, step 312 is otherwise turned to;

The step is with step 204, and details are not described herein again.

Step 305, in it can provide the homogeneous frequency adjacent area of MBMS business, judge and cell-of-origin has the identical areas MBSFN The co-frequency neighbor cell of domain identifier whether there is, if so, turning to step 306, otherwise turn to step 312;

UE can determine the MBSFN area identifications of homogeneous frequency adjacent area according to the instruction of the MBSFN area identifications of neighboring community Whether identical with cell-of-origin, if be different from, there is no have the same frequency neighbour of identical MBSFN area identifications small with cell-of-origin Area is (since the embodiment is UE in the interregional movements of MBSFN, it is likely that there is no have identical regions MBSFN to mark with cell-of-origin The homogeneous frequency adjacent area of knowledge)

Step 306, MBMS business will can be provided and have the homogeneous frequency adjacent of identical MBSFN area identifications small with cell-of-origin Area is ranked up.

There is the small of identical MBSFN area identifications with cell-of-origin when existing in the homogeneous frequency adjacent area that can provide MBMS business Area, and when having multiple (more than one), then UE utilizes R criterion according to the quality of wireless channel for measuring these obtained cells (R-criterion) these cells are ranked up, it is possible thereby to confirm the best homogeneous frequency adjacent area of quality of wireless channel.

Step 307, UE selection targets cell.

If MBMS business can be provided and with cell-of-origin there is the homogeneous frequency adjacent area of identical MBSFN area identifications to only have One, then UE is as Target cell;
