A method for carrying out addressing of terminal receiving multimedia broadcast multicast service uses time slot number as addressing parameter of terminal based on existed addressing mode i.e. uses MBMS-BEARER-ID + MS-ID in existing protocol and time slot down sent by radio link control / media access control packet to decide addressing of terminal commonly.
Description
Technical field
The present invention relates to moving communicating field, the particularly multimedia broadcast multicast service of cordless communication network (MBMS:Multimedia Broadcast Multicast Service) relates to a kind of to receiving the terminal method for addressing of MBMS specifically.
Background technology
In communication system, the multimedia broadcast multicast service MBMS by wireless network can provide data to download streaming media service.File is downloaded, and business such as mobile TV also can realize by MBMS.MBMS provides the carrying service to multiple spot of unidirectional point, is used for transmitting data from a source point to a plurality of recipients, and this mode has significantly reduced the transfer of data in the network, more efficient use resource.At wave point, a plurality of users receive same data at shared point to the channel of multiple spot, can not cause obstruction because of the same data of Channel Transmission of the point-to-point that uses a plurality of special uses.In network, same data are at interface on transmission primaries.
As shown in Figure 1, be the network architecture diagram of MBMS, the point that dotted line is wherein represented to share is to multiple spot (P-T-M:Point-to-Multipoint) channel.From Serving GPRS Support Node (SGSN:ServingGPRS Support Node), for the same data that send to Cell Site Controller (BSC:Base StationController), no matter have what sub-districts (BTS:Base Trans-ceiver Station) and user need receive these data under this BSC, SGSN only sends out a secondary data to this BSC.According to present 3GPP (3th Generation Partnership Project; Third generation affiliate engineering) agreement, when base station system (BSS) receives that multimedia broadcast multicast service conversation from SGSN begins request (MBMS SESSION START REQUEST) message, if in the sub-district of this BSS control the sub-district that belongs to this MBMS service area is arranged, create the MBMS business contexts so, send the multimedia broadcast multicast service conversation simultaneously and begin to reply (MBMS SESSION START RESPONSE) message to SGSN.BSS begins to set up the MBMS channel in all belong to the sub-district of this MBMS service area.
Followingly describe with reference to 2,3,4 pairs of flow processs of setting up the MBMS channel of accompanying drawing.Wherein, Fig. 2 is not for having counting and not having schematic flow sheet under the PTM carrying (No counting and no PTM Bearer defined); Fig. 3 is the schematic flow sheet under the situation of usage count (Counting used); Fig. 4 sets up (Bearer established) schematic flow sheet for the PTM carrying.
The flow process of setting up the MBMS channel comprises:
Notify (Pre-notification) (this step is an optional step) in advance to the MBMS business that is about to begin to transmit data;
Notice to the user of all these MBMS business in the sub-district;
Counting flow process (this step is an optional step) to the user;
A channel assignment message, the channel type of distribution depend on the user's number that responds in the inherent counting flow process of sub-district.
If do not count flow process, notice and channel allocation can issue (as shown in Figure 2) in a packet paging request (PacketPaging Request) message.
Below to the counting flow process describe.
The notice that network can be informed the professional and session of the MBMS of user terminal (UE:User Equipment) that is in idle (Packet idle) pattern of grouping by the mode of prenoticing at hand.Wherein, pre-notice can be in packet paging request (PAGING REQUEST) type (TYPE) 1 or 2 on the general controls channel (CCCH:Common Control Channels); Perhaps issue in the PACKET PAGINGREQUEST message in grouping general controls channel (PCCCH:Packet Common Control Channels), comprising the Temporary Mobile Group Identity (TMGI:Temporary mobilegroup identity) and the MBMS session identification (MBMS Session Identify (ID)) that may exist.For being in Packet Idle pattern and will receiving the UE of above-mentioned MBMS business, after receiving pre-notice, enter non--discontinuous reception (non-DRX:non-discontinuous reception) pattern, and monitor session and begin notice.
When BSS receives the message that the MBMS session begins, follow control channel (PACCH:Packet Associated ControlChannel) or Dedicated Control Channel (DCCH:Dedicated Control Channel) to inform UE by packet paging channel ((P) PCH:PacketPaging Channel), grouping.This moment, BSS may initiate counter mechanism in some sub-district, to judge in each sub-district the interested UE number of this business was used for selecting the radio bearer of MBMS.
For the UE that is under Packet Idle or medium access control-free time (MAC-Idle) state, network is by Paging Request Type1 on general controls channel CCCH or the PCCCH or 2 message informing UE, comprise TMGI in this message, if have MBMS Session Identity simultaneously, be also contained in this message.The channel that may also comprise MBMS Packet Random Access Channel (MPRACH:MBMS Packet Random Access Channel) in the notification message is described.The MPRACH channel is specifically designed to the user number counting flow process.Consistent under the default situation of the Control Parameter of this MPRACH with the Packet Random Access Channel (PRACH:Packet Random Access Channel) of above-mentioned sub-district, perhaps in notification message, issue.If do not add above-mentioned MBMS business before the UE or received above-mentioned business, UE abandons current message.If UE did not receive above-mentioned session, and require user number counting in the notification message, UE will begin to count flow process (as shown in Figure 3).
For the UE that is in transmitted in packets (Packet transfer) or medium access control-shared (MAC-Shared) state, BSS follows control channel PACCH to issue MBMS notice (MBMS ANNOUNCEMENT) message by grouping, and this message comprises TMGI and the MBMS Session Identity that may exist; May comprise also whether explanation exists the parameter of maximum response time or MBMS session persistence, explanation of MPRACH channel resource and Control Parameter, and the channel allocation information of MBMS session.If do not add above-mentioned MBMS business before the UE or received above-mentioned business, UE abandons current message; Otherwise UE stores the MBMS information in this message, timer of initialization (if having maximum response time or session persistence to require), and above-mentioned message submitted to upper-layer protocol.If overtime, the deletion canned data if get back to Packet Idle or MAC-Idle state in this process, starts the user number counting flow process.
For the UE under dedicated mode or Radio Resource control-cell-specific (RRC-Cell Dedicated) pattern, BSS issues MBMS ANNOUNCEMENT message on the DCCH channel, this message comprises TMGI and the MBMS Session Identity that may exist, may comprise also whether explanation exists the parameter of maximum response time or MBMS session persistence, explanation of MPRACH channel resource and Control Parameter, and the channel allocation information of MBMS session.If do not add above-mentioned MBMS business before the UE or received this business, UE abandons current message.Otherwise UE stores the MBMS information in this message, timer of initialization (if having maximum response time or session persistence to require), and above-mentioned message submitted to upper-layer protocol.If overtime, the deletion canned data if get back to Packet Idle or MAC-Idle state in this process, starts the user number counting flow process.
Below user number counting started flow process describe.
In a sub-district, do not have UE interested, do not distribute this MBMS Traffic Channel in this sub-district certain MBMS business.The user number counting flow process is exactly the number that is used for calculating in certain sub-district the professional interested UE of MBMS.If comprise the MPRACH resource description in the notification message, UE is by sending out the message initiated counting flow process of packet channel request (monolithic MBMS access) (PACKET CHANNEL REQUEST (Single Block MBMSAccess)) on MPRACH.If do not distribute MPRACH, UE goes up in (grouping) Random Access Channel ((P) RACH) and sends out (Packet) Channel Request (Single Block MBMSAccess) message.
Network will distribute a uplink data block to give UE.In this uplink data block, i.e. grouping follows control channel PACCH, UE to send out multimedia broadcast multicast services request (MBMS SERVICE REQUEST) message.Comprise in this message: the TLLI of UE (TLLI:Temporary Logical LineIdentifier), TMGI, and the MBMS Session Identity that may exist; Portable terminal (MS) enters the non-DRX pattern simultaneously.The network based MBMS SERVICE REQUEST message of receiving is estimated in certain sub-district the interested UE of certain MBMS session, thereby whether decision adopts the Point-to-Multipoint channel.
When adopting the PTM channel, may set up a up feedback channel, to receive the feedback message of UE, this need be to the UE addressing.
Below (Bearer established) set up in MBMS carrying describe.
Network may comprise the description of MBMS carrying in notification message.The MBMS carrying that distributes by notification message is a non-automatic repeat requests (ARQ:Automatic Repeat Request).Network can issue MBMS by (grouping) access grant channel ((P) AGCH:Packet Access Grant Channel) and distribute (MBMS ASSIGNMENT) message to give all to being in the interested UE of Packet Idle pattern.Network can be by not distributing the PTM carrying in PTM carrying of above-mentioned distribution of messages or this sub-district of notice UE.MBMS ASSIGNMENT message also can be issued a specific UE who is inserting.
MBMS ASSIGNMENT message comprises IMGI, session identification (Session Id), and multimedia broadcast multicast service carrier sign (MBMs_BEARER_ID) and PTM channel are described.If do not distribute the PTM carrying, illustration: current area allows the access once more to above-mentioned MBMS session; Current area no longer allows the access to above-mentioned MBMS session; Current route district no longer allows the access to above-mentioned MBMS session; Current Public Land Mobile Network network (PLMN) no longer allows the access to above-mentioned MBMS session.And for preventing information dropout, MBMS ASSIGNMENT message can repeat to issue in network.
Below the distribution of MBMS station address is described.
For the terminal equipment that receives the MBMS business, network can distribute the address for them, i.e. mobile terminal identification (MS_ID).Distribute the benefit of address to have: when establishing uplink feedback channel, network based MS_ID comes designated user to give row reception response message; When the terminal that receives the MBMS business is carried out paging, can on the PACCH channel, come calling user by MS_ID.MS_ID can also can issue by the MBMS ASSIGNMENT message of point-to-point by follow MBMS MS_ID ASSIGNMENT (distribution of the MBMS mobile terminal identification) distribution of messages that issues on control channel/descending (PACCH/D) channel in grouping.MS_ID distributes in the scope of a MBMS carrying, and it just can distinguish different terminals with MBMS bearing identification (MBMS_BEARER_ID) combination.That is to say, MBMS_BEARER_ID+MS_ID can be in professional shared time slot (one or more) scope of this MBMS unique definite receiving terminal.
Stipulate in the agreement at present, MBMS_BEARER_ID+MS_ID takies the position of temporary flow identity (TFI:TemporaryFlow Identifier), account for 5 bits altogether, wherein MBMS_BEARER_ID accounts for a bit at least, so MS_ID can only account for 4 bits at most, that is to say that network at most can only be to 16 user's addressing for the user who receives same MBMS business in a sub-district.
The limitation of MBMS realization at present is that for a MBMS business, distribute MS_ID at a point in the radio bearer scope of multiple spot, this MS_ID does not consider the factor of multi-slot.Because the MBMS business is broadcasting service, its professional shared radio bearer resources is not change with what of user, so the user is many more, efficient is high more; The previous MBMS business of order can only for the user that can not distribute MS_ID, not only can not be sent out uplink feedback information to 16 user's addressing at most, but also must monitor the paging channel of sub-district simultaneously, and influence is to the reception of MBMS business.
