Below, the session while take MBMS system architecture based on LTE system starts flow process as example, session is started to flow process and be specifically addressed.
During MBMS system architecture based on LTE system, session starts flow process and comprises the following steps:
Step 301, BM-SC initiate Session Start Request, and Session Start Request is sent to MBMS GW.
Here, in Session Start Request message, increase the relevant indication information (small data indication) of small data, concrete, small data indication can comprise the information such as small data indication information, data volume size information.Wherein, small data indication information (indicating current group data is small data), data volume size information starts automatically to discharge small data after flow process in order to execute in the future session, and discharges group data without carrying out conversation end flow process again.Here, above-mentioned group data transmission request is specially Session Start Request in this flow process.
Step 302, MBMS GW return to Session Start Response to BM-SC.
Step 303, MBMS GW send to MME by Session Start Request.
Here, this Session Start Request still carries the small data indication of increase.
Step 304, MME send to E-UTRAN by Session Start Request.
Here, this Session Start Request still carries the small data indication of increase.
Step 305, E-UTRAN return to Session Start Response to MME.
Step 306, MME return to Session Start Response to MBMS GW.
Step 307, E-UTRAN carry out RAN Resource Setup.---resource is distributed and channel configuration process.
Here, resource is distributed and channel configuration process is specially: the MCE in E-UTRAN determines and adopts the above-mentioned transmission means of eating dishes without rice or wine to carry this group data according to small data indication, and by MBMS scheduling message (MBMS SCHEDULING INFORMATION), be the parameter of each eNB configuration MCCH in this group data sending zone, indication eNB is carried at small data in MCCH message, and when configuration MCCH update time (MCCH Update Time), consider that MBMS GW sends small data to eNB, and eNB encapsulation small data needed delay time during to MCCH, thereby can when arriving, delay time receive exactly the small data content of renewal.
Step 308, E-UTRAN carry out IP address multicast and add, to carry out follow-up MBMS transfer of data.
Step 309～step 310, MBMS transfer of data.
Corresponding to step 308, step 309～step 310, eNB, from MCE receives MCCH parameter configuration, receives the small data content that MBMS GW sends over.
ENB has in the mode of MCCH channel group data:
1) in existing MBMS single-frequency network area configuration (MBSFNArea Configuration) message, increase a cell, carry small data;
2) in existing Physical Multicast Channel information (PMCH-info), increase a cell, carry small data;
3) in MCCH channel, newly increase a message, to carry small data, similar counting (counting) order, and be configured in MCCH.
When MCCH Update Time arrives, eNB broadcasts new MCCH message on the MCCH channel of eating dishes without rice or wine.UE receives MCCH message, according to small data indication wherein, reads the small data content in the corresponding signaling of taking respectively above-mentioned three kinds of transmission meanss.
Here it is to be noted: during MBMS system architecture based on 3G design, session starts flow process and above-mentioned session based on LTE system, and to start flow process be similar, just network entity is distinguished to some extent, and MME is replaced to SGSN, and E-UTRAN replaces to UTRAN.That is to say, method of the present invention had both been applicable to the situation that Access Network is E-UTRAN, was applicable to again the situation that Access Network is UTRAN.
In sum, the present invention and existing MBMS session flow process have following difference:
Need in step 301,303,304 Session Start Request message, add small data indication, concrete can comprise the information such as small data indication information, data volume size information.
In the RAN of step 307 Resource Setup process, it is upper that MCE determines that small data is carried on to MCCH, can adopt any data that realize eating dishes without rice or wine in foregoing three kinds of transmission meanss to send, and configure MCCH parameter; ENB will assemble MCCH message and send eating dishes without rice or wine according to the requirement of MCE.
Owing to being small data, BM-SC can be as existing MBMS operation flow, also need triggering session process ends, therefore, eNB transfers after small data, directly discharges the relevant content of this small data in MCCH, and MME/MCE/MBMS-GW discharges the information of this small data automatically, do not need to carry out the conversation end flow process showing, thereby saved signaling consumption.
Below in conjunction with accompanying drawing, the enforcement of technical scheme is described in further detail.
Embodiment mono-: take E-UTRAN as example, eNB is above-mentioned the first transmission means in the mode of MCCH channel group data, in existing MBSFN Area Configuration message, increases a cell, carries small data.
