Problems solved by technology

[0035] First: The RLC layer and the MAC layer belong to different protocol layers, and each layer has its own corresponding control process. If RLC and MAC are implemented in the same module, the respective control processes of the RLC layer and the MAC layer must be satisfied at the same time. Increased complexity of RLC and MAC layer design

Embodiment Construction

[0070] The preferred embodiments of the present invention will be described in detail below with reference to the accompanying drawings.

[0071] In order to illustrate the application of this invention in GMR mobile terminal products more clearly, first, an example is given to illustrate how the RLC / MAC module assembles uplink data blocks for transmission. There are two ways for the terminal to send uplink data, one is to send uplink data on the DCH channel , and the other is to send uplink data on the PDCH channel. Since the processing flow is similar, it will be described in one flow. Its software architecture is as figure 1 As shown, the specific process is as follows figure 2 shown.

[0072] As shown in the figure, uplink data transmission includes the following steps:

[0073]Step 1: The terminal initiates a data transmission process on the PDCH or DCH channel. First, the terminal performs a random access process, and then the network side allocates PDCH or DCH radi...

Abstract

The invention relates to a realizing method for RLC and MAC layers in a mobile communication system. The method comprises the steps: detaching the headers of RLC / MAC to complete in the RLC layer and the MAC layer; in the downstream direction, receiving the header data of RLC / MAC from the network by the MAC layer, if the header is the control header, analyzing the MAC layer information data in the header by the MAC layer, reporting the analyzing result to the RLC layer, if the header is the data header, analyzing the header data of the RLC / MAC by the MAC layer, reporting the data to the RLC layer and reporting the header field content of the analyzed RLC / MAC header; and in the upstream direction, if the MAC layer needs to send the RLC / MAC control header, requesting the RLC layer control information to the RLC layer by the MAC layer, and the information of RLC / MAC header field, if the MAC layer needs to send the data header, requesting the RLC layer to send the RLC data by the MAC layer, and the field content of the RLC / MAC header.

Description

technical field [0001] The invention belongs to the technical field of GMR mobile terminal equipment (abbreviation: MES), and relates to an implementation method of RLC and MAC layers in a mobile communication system, which is used to solve the development and design of the high-level protocol RLC / MAC in the GMR mobile terminal. Background technique [0002] In the geostationary satellite communication system (abbreviation: GMR), the air interface is developed on the basis of the existing global digital mobile communication system (abbreviation: GSM). The air interface of GMR is as follows: figure 1 shown. figure 1 It is the current mobile communication protocol architecture of the general air interface. The non-access layer (abbreviation: NAS layer) is mainly responsible for processing core network-related content, and this part has no direct relationship with the access network. Radio Resource Control (abbreviation: RRC) is mainly responsible for the allocation, use, appl...
