Description
Technical field
The present invention relates to multimedia technology field, specifically relate to a kind of method that issues travelling carriage address designation (MS_ID) and allocation identification for travelling carriage.
Background technology
At present, the multimedia broadcast multi-broadcasting business of wireless network (MBMS) can provide multiple multimedia service to the user.Such as, can provide data download, streaming media service etc. by MBMS.Business such as common file download, mobile TV 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.This transmission means can significantly reduce the transfer of data in the network, can more effectively utilize resource.
With the wireless transmission in the third generation partner program (3GPP) is example, and this transmission course as shown in Figure 1.Send to the same data of Cell Site Controller (BSC) for needs, no matter have what sub-districts (BTS) and user need receive these data under this BSC, Serving GPRS Support Node (SGSN) only need send once these data to BSC.In addition, a plurality of users under the BTS can receive the MBMS business to multiple spot (P-T-M) channel by the point of sharing.This shows that based on the transmission means of MBMS business, data same in the network are at interface on transmission primaries.And at wave point, a plurality of users receive same data to the channel of multiple spot at shared point, just the situation of channel block can not occur occurring because of the same data of Channel Transmission of the point-to-point that uses a plurality of special uses.
Below to being described to the processing procedure that the user sends data by MBMS.
According to present 3GPP agreement, wireless access network (the GERAN of global system for mobile communications/evolution type high-speed data transfer, GSM/EDGE RAN) when receiving that MBMS from SGSN begins queued session (MBMS SESSION START REQUEST) message, if some sub-district belongs to the service area of this MBMS in the sub-district of this GERAN control, then GERAN need create the context of MBMS business, sends the MBMS session simultaneously and begins to reply (MBMS SESSION STARTRESPONSE) message to SGSN.And GERAN also need set up the MBMS channel in all belong to the sub-district of this MBMS service area.
The flow process that GERAN sets up the MBMS channel generally includes:
Steps A, the MBMS business that is about to begin to transmit data is notified in advance;
The user of all these MBMS business in step B, the notifying cell;
Step C, to user's counting flow process;
Step D, by channel assignment message the channel type that is distributed is handed down to the user afterwards.
Wherein, above-mentioned steps C comes in the calculation plot number to the professional interested travelling carriage of MBMS by the counting flow process; Above-mentioned steps D can distribute corresponding channel type and channel resource according to this result of calculation.
After distributing channel, can issue the MBMS business to the user by this channel.
In addition, for the user terminal that receives the MBMS business, network can also distribute MS_ID for it.Distribute the benefit of MS_ID to have: when setting up uplink feedback channel, network can be given row according to the MS_ID designated user and receive response message; When the user who receives the MBMS business is carried out paging, can on the PACCH channel in the MBMS carrying, come this user of paging by MS_ID.
At present, MS_ID can also can pass through the MBMS ASSIGNMENT distribution of messages of point-to-point by the MBMS MS_IDASSIGNMENT distribution of messages that issues on the PACCH/D channel.MS_ID distributes in the scope of a MBMS carrying, and MS_ID just can distinguish different users with the combination of the ID of MBMS carrying.The ID of MBMS carrying is MBMS_BEARER_ID, therefore, MBMS_BEARER_ID+MS_ID can be in the professional shared time slot scope of this MBMS the user of unique this MBMS business of definite reception.
For the user who has distributed MS_ID, network can be by the mode of regularly inquiring about, allow the user send the descending affirmation/nack message of MBMS (MBMS Downlink Ack/Nack) and give network, network can know that thus whether this user is also in this MBMS business of reception.User's gravity treatment to other sub-district, stop to receive MBMS business or other reasons and cause network repeatedly to inquire about this user not receive that all when replying accordingly, network promptly discharges this MS_ID.After discharging MS_ID, through a guard time at interval, this MS_ID can distribute to other users again.
Above-mentioned first kind of method of salary distribution specifically is that to receive MBMS the user be that those users that carried out the user number counting process of above-mentioned steps C distribute MS_ID by MBMSMS_ID ASSIGNMENT message when professional.And this method both can be redistributed MS_ID for the user who has distributed MS_ID, can distribute MS_ID for the user who does not have MS_ID again.
But when distributing MS_ID, may have problems for the user who did not distribute MS_ID.Because do not have MS_ID before this user, network can't regularly be inquired about this user by MS_ID, thus network really this user after finishing counting process whether also in this MBMS business of reception.At this situation, present 3GPP regulation need repeat to issue several times MBMS MS_ID ASSIGNMENT message, if do not receive user answer, thinks that then this user does not receive the MBMS business, does not therefore need to distribute MS_ID to this user.Obviously, if this user has not received the MBMS business, it is just nonsensical that then network continues to issue MBMS MS_ID ASSIGNMENT message, and network can not be received replying of user.And do not received the user under the situation of MBMS business and repeated to issue this message, can bring the bigger wasting of resources to network.
In addition, the user is just passively by network allocation MS_ID at present, and the user can't learn the information of network, such as, the user does not know the current idle MS_ID that whether has.
Summary of the invention

Embodiment
Below in conjunction with drawings and the specific embodiments the present invention program is described in detail.
The present invention program at first by network with receiving the travelling carriage of MBMS business in the current information notification current area that idle MS_ID arranged, make travelling carriage can obtain the MS_ID information of network.
Wherein, the idle MS_ID in the network can be the idle MS_ID that has just existed when the professional beginning of this MBMS, also can be the idle MS_ID that the release flow process by MS_ID discharges, and can also obtain by additive method.
Network can be informed the current MS_ID that has the free time of user in several ways.A kind of preferable implementation is exactly to inform the user by the mode of broadcasting, and comparatively common mode is broadcasted by broadcast exactly.Provide another kind of broadcasting implementation method below:
Owing in the data head of Radio Link control/medium access control (RLC/MAC) data block of the MBMS business that is handed down to travelling carriage, correlation reserved block field (RRBP is arranged, Relative ReservedBlock Period) field and ES/P (S/P) field, in present agreement, when the ES/P field is 00, the S/P field is 0 o'clock, the RRBP field is a spare field, so the present invention program's proposition, can identify the current idle MS_ID that exists by this RRBP field.Such as, can set in advance a state of RRBP field, the current MS_ID that has the free time of this state representative, if the RRBP field in the data head of the RLC/MAC data block that travelling carriage is received is set state, and the ES/P field be 00 or the S/P field be 0, then travelling carriage can be learnt that network is current and has an idle MS_ID.
Wherein, when the state of RRBP field is set, two states can be set specifically, there is idle MS_ID in a state representative, and another state is then represented and do not had idle MS_ID.Such as, first bit that the RRBP field is set is the current MS_ID that has the free time of 1 interval scale, is the current MS_ID that does not have the free time of 0 interval scale.Like this, network can be given the user with the current information broadcast of idle MS_ID that whether exists by set state information when issuing the RLC/MAC data block of MBMS business.
Based on above-mentioned processing, travelling carriage has obtained the MS_ID information of network, and therefore, the present invention can initiatively initiate request by travelling carriage when being embodied as travelling carriage distribution MS_ID.Realize entire process flow process that MS_ID distributes as shown in Figure 2, corresponding following steps:
Step 201, network inform that with this situation all are receiving the travelling carriage of MBMS business in the current area when idle MS_ID is arranged.
This step is the processing that above-mentioned network will have the information notification travelling carriage of idle MS_ID.
Step 202, travelling carriage are learning that there is idle MS_ID in network, and when determining self need distribute MS_ID, access network, and initiatively initiate the request message that request distributes MS_ID.
Step 203, network are after receiving the request message of travelling carriage, for this user distributes MS_ID.
Can be embodied as the user by above processing and distribute MS_ID.
In above-mentioned steps 202, need to carry the sign of this travelling carriage and the sign of the current MBMS business that receives of this travelling carriage in the MS_ID request message that travelling carriage sends.In step 203, network then is designated this travelling carriage according to these two and distributes corresponding M S_ID.
And in above-mentioned steps 202,, then need access network if travelling carriage before initial request messages, does not also have access network.Specifically, travelling carriage can pass through channel request (CHANNEL REQUEST) message of Random Access Channel (RACH) or packet channel request (PACKET CHANNEL REQUEST) the message access network of Packet Random Access Channel (PRACH), and network then is this travelling carriage Resources allocation.In this case, the pairing message flow sequential of above-mentioned steps 202 and 203 handling processes as shown in Figure 3.Wherein, request (MS_ID REQUEST) message of the MS_ID among Fig. 3 and MS_ID distribution (MS_ID ASSIGNMENT) message are newly-installed message.Certainly, also new message can be set, but the information in this message is sent by existing message.
In addition, in above-mentioned steps 202, travelling carriage also may occur before initial request messages, receive the information that does not have idle MS_ID that network sends again, then travelling carriage should stop to initiate to ask to distribute the request message of MS_ID.Certainly, if received again afterwards that travelling carriage had the information of idle MS_ID, then this travelling carriage initial request messages again is its distribution MS_ID with the request network.
In above-mentioned steps 203, owing to have a plurality of Mobile Origination requests, and the number of idle MS_ID is limited, therefore, network may distribute MS_ID for all travelling carriages.In light of this situation, network is in a minute timing, if there is idle MS_ID, then the MS_ID that will distribute to this travelling carriage by the MS_ID assignment messages sends to travelling carriage.If there is no MS_ID then informs travelling carriage by the MS_ID assignment messages, has not had idle MS_ID at present.Travelling carriage then need be after network sends the information of idle MS_ID next time, and asking network again is that it distributes MS_ID.
The above only is the present invention program's preferred embodiment, not in order to limit protection scope of the present invention.
