Problems solved by technology

[0019] It can be seen from the above processing flow that in the prior art solution, the sender needs to determine whether to set a storage indication for each PDU, and also needs to distinguish between PDUs with storage indications and PDUs without storage indications before sending to determine Whether storage is required, and it is required that SDUs with storage instructions and SDUs without storage instructions cannot be cascaded into the same PDU; correspondingly, the receiver also needs to change the process before realizing the out-of-order function, so that the The processing of RLC UM entities becomes very complicated; and, if the RLC scheduling algorithm is unreasonable, the transmission of MBMS information will be delayed

Embodiment Construction

[0046] The core idea of ​​the present invention is to save all the data that needs to be retransmitted by the RLC UM while sending. Here, the retransmitted data may be criterion information in MCCH information, or scheduling information of MSCH logical channel. The following only takes the processing of the criterion information in the MCCH information as an example.

[0047] For the MCCH information, the idea of ​​the present invention is: to process the criterion information and the non-criteria information separately, and establish two RLC UM entities with identical functions at the sender and the receiver, which are respectively used to process the criterion information and the non-criteria information. In this way, The processing of PDUs carrying non-standard information is exactly the same as that of the prior art, and each PDU carrying standard information is uniformly stored, without setting a storage instruction and distinguishing whether the currently processed PDU n...

Abstract

A method for transmitting multimedia broadcast / multicast service information includes packing received service data unit SDU to be PDU when data sent from high layer is received by RLC UM entity of sending party, sending packed PDU to low layer and storing sent PDU.

Description

technical field [0001] The invention relates to information transmission technology, in particular to a method for transmitting MBMS information in Multimedia Broadcast / Multicast Service (MBMS). Background technique [0002] With the development of third-generation mobile communication technology, people's demand for mobile communication is no longer satisfied with voice services. Since the third-generation mobile communication can provide services with higher data rates than the second-generation mobile communication, a large number of multimedia services Emerged, such as: video calls, picture downloads, high-speed browsing Internet services and other services. Among them, some application services require multiple users to receive the same data at the same time, such as: video on demand, TV broadcast, video conferencing, online education, interactive games and so on. [0003] In order to effectively utilize the resources of the mobile communication network, the third-gene...
