Problems solved by technology

[0012] Due to current protocol limitations, the E-bit in the PDU of MBMS RLC can only be interpreted in the normal mode
Therefore, for a service with a fixed size of service data frame, even if one RLC SDU frame can be encapsulated in one RLC PDU, it is still necessary to add an LI to indicate the end of the data segment, which wastes radio resources

Embodiment Construction

[0036] The core idea of ​​the present invention is: adding an optional extension bit explanation (Alternative E-bit interpretation) optional information element in the MBMS radio link control protocol information (RLC infoMBMS) information element; The E-bit in the PDU of the road layer RLC layer is interpreted as supporting the optional mode. When the information element does not exist, the interpretation of the E-bit in the PDU representing the RLC layer is the same as the prior art, and it is a normal extension bit interpretation.

[0037] Optional extended bit interpretation, also known as Alternative E-bit interpretation, is shown in the following table:

[0038] Table 2. Explanation of optional extension bits

[0039] bit describe 0 The next field is a complete SDU, no

with segmentation, concatenation or padding

[0040] 1 The next field is length indication and E-bit

[0041] In this case, if you need to encapsulate an RLC SDU ...

Abstract

The invention discloses a configuration method for enabling MBMS service to support optional extension bit interpretation, comprising: adding optional extension bit interpretation optional information elements in MBMS radio link control protocol information cells. The invention also discloses a method for carrying out MBMS service session, which is applicable to the situation when the service data unit is of fixed length, including: adding an optional extension bit in the information cell of the MBMS radio link control protocol to explain the optional cell; The radio network controller carries the optional extension bit interpretation information element in the session configuration information and sends it to the user terminal; after receiving the session configuration information, the user terminal configures a module responsible for receiving or parsing accordingly, and saves the optional extension bit interpretation configuration; The radio network controller and the user terminal perform the MBMS service session according to the interpretation of optional extension bits. By adopting the method of the invention, resources can be saved for MBMS services with fixed code lengths such as speech, and the backward compatibility is very good.

Description

technical field [0001] The invention relates to the field of communication, in particular, a conversation method supporting optional extension bit interpretation of MBMS (Multimedia Broadcast Multicast Service) in the third generation mobile communication system. Background technique [0002] Multimedia Broadcast / Multicast Service (MBMS) is a technology for sharing network resources and transmitting data from one data source to multiple targets. In order to effectively utilize mobile network resources, 3GPP (Third Generation Partnership Project, 3rd generation partner project) proposed the MBMS service in R6, that is, to provide a data source in the mobile network to send data to multiple users point-to-multipoint business, realize network resource sharing, and improve the utilization rate of network resources, especially the precious air interface resources. MBMS can not only realize plain text and low-rate message multicast and broadcast, but also realize multicast and br...
