This method of notifying user MBMS service conversation to finish of the present invention, in MBMS business data transmission process, network side finishes signaling with session and sends to user equipment (UE) simultaneously with transmission business datum piece, UE stops to receive the MBMS business datum according to the conversation end signaling after demodulating the conversation end signaling when receiving business datum.
Below two embodiment are described respectively.
First preferred embodiment:
Referring to Fig. 3, Fig. 3 is the transmission of data blocks schematic flow sheet of the present invention's first preferred embodiment.This flow process may further comprise the steps:
Step 301, network side are in the end adhered to the conversation end signaling in a data block.
Last data block that step 302, network side will have been adhered to the conversation end signaling sends to UE.
In a MBMS business data transmission process, BM-SC is known, and what will transmit is last data block in this session, and this moment, BM-SC adhered to conversation end (SessionStop) signaling in this data block back.If this MBMS business is to come from outside MBMS service providers such as PDN, BM-SC is the information that obtains last data block from this MBMS service provider so.
Last data block that BM-SC will adhere to the conversation end signaling sends to UE by GGSN, SGSN, BSC/RNC by air interface.Detailed process comprises following 4 steps:
1) BM-SC will adhere to the data block of conversation end signaling, send to the GGSN that has registered this MBMS business;
2) be transmitted to SGSN after the GGSN data block that will comprise the conversation end signaling is handled;
3) be transmitted to BSC/RNC after the SGSN data block that will comprise the conversation end signaling is handled;
4) send to UE after the BSC/RNC data block that will comprise the conversation end signaling is handled.
Wherein GGSN, SGSN, BSC/RCN processing that data block is carried out may be that data block is carried out cascade, cuts apart, and adds the first-class processing of agreement, and the concrete mode of handling is same as the prior art, repeats no more here.
BM-SC is when last data block among the session of transmission, can directly session not finished signaling attached in last data block, but the relevant information of last data block is sent to BSC/RNC, BSC/RNC determines that according to last data block information which data block is last data block, additional Session Stop signaling after it passes to last data block of user, or RNC notifies user Session Stop information by other signal transmission method.
Step 303, UE carries out demodulation to the data block that receives, owing to also have other in-band signalling in the data, so UE carries out demodulation to the data block of each reception.
Step 304, UE demodulates and comprises Session Stop signaling in the data block, stops to receive the MBMS business datum at once.
In fact Session Stop letter is modern also can transmit on the arbitrary data piece in session, and second preferred embodiment of the present invention is being transmitted Session Stop signaling on the data block arbitrarily.Referring to Fig. 4, Fig. 4 is the transmission of data blocks schematic flow sheet of the present invention's second preferred embodiment.This flow process may further comprise the steps:
Step 401, network side determine after a data block is adhered to the conversation end signaling, sends the data block indication signaling by the MCCH channel to UE, also has what data blocks after wherein indicating network side adheres to the conversation end signaling in transmission data block.
Step 402, network side finishes session in the data block of signaling attached to its decision.
Certainly, network side also can send the data block of adhering to the conversation end signaling earlier, sends the data block indication signaling to UE again.
Step 403, network side sends the data block of having adhered to the conversation end signaling.
In the present embodiment, network side sends the method for the data block adhere to the conversation end signaling can be identical with the described embodiment method of Fig. 3, just data block last data block not necessarily.
Step 404, UE carries out demodulation to the data block that receives, owing to also have other in-band signalling in the data, so UE carries out demodulation to the data block of each reception.
Step 405, UE demodulates and comprises Session Stop signaling in the data block, begins data block is counted.
Step 406, UE after receiving last data block, stops to receive the MBMS business datum according to the data block quantity in the indication signaling of step 401.
Among above-mentioned two embodiment, the conversation end signaling can be attached to data block original position or end position or centre position, and UE can both come out the modern demodulation of this letter exactly.
In addition, network side can also finish session to believe to also have how many data blocks to want information transmitted to join in the conversation end signaling from now on;
When UE receives business datum data block is carried out demodulation, when UE will demodulate the conversation end letter from now on from data block, want information transmitted according to also having how many data blocks in the conversation end signaling, begin the data block that receives is counted, when receiving last data block, stop to receive the MBMS business datum.
Like this, just do not need to start original conversation end flow process has notified the UE conversation end to network.Certainly, if UE does not demodulate the conversation end signaling after receiving all data blocks, UE can also receive the conversation end signaling by former conversation end flow process, stops to receive the MBMS business datum according to this conversation end signaling.
In former session flow process, BSC/RNC can receive that also conversation end letter that core net sends from now on, receives signaling with session and sends to UE as in-band signalling by air interface, can make UE stop to receive the MBMS business datum as early as possible.
By the above embodiments as seen, this method of notifying user MBMS service conversation to finish of the present invention makes UE in time stop to receive the MBMS business, and then has reduced the power consumption of UE.
