Embodiment Construction

[0052] In order to explain the function of the present invention more clearly, first briefly explain the flow chart of the service data of the base station internal interface unit and the baseband processing unit. Such as figure 1 As shown, the downlink service data sent from the base station controller is converted into the internal transmission protocol format of the base station after being decoded by the base station interface unit, and is transmitted from the interface unit to multiple baseband processing units, and the uplink service data is transmitted from multiple baseband processing units through The internal transmission protocol is sent to the interface unit, and then converted into an external transmission protocol by the interface unit and sent to the base station controller. The external transfer protocol and the internal transfer protocol can be the same or different, and they are designed independently. In the current design of the internal transmission netwo...

Abstract

MAC adaptation layer is introduced on data link layer of internal interface in interface unit and base band processing unit. The MAC adaptation layer comprises header of MAC adaptation layer and service data unit. The said header of MAC adaptation layer includes four fields: ID of link, message length ID, subsections ID of data packet and sequence number of subsection. Transmission service data include transmission data and receiving data. Advantages are high transmission efficiency and low processing spending. Comparing with prior art, the invention possesses features of simple processing mechanism and simplified program codes.

Description

Technical field: [0001] The invention relates to a method for transmitting real-time service data inside a base station subsystem of a mobile communication system. Background technique: [0002] With the continuous development of mobile communication system applications, people have higher and higher requirements for mobile communication system equipment, especially the base station system equipment is the focus and key of the entire mobile communication system equipment. Among them, with the introduction of high-speed data services, high-efficiency high-speed service data transmission and processing in base station equipment has also become one of the topics that people pay attention to. Currently, various transmission technologies are used between the base station and the base station controller, such as Asynchronous Transmission Mode (ATM) and IP (Internet Protocol), etc. These technologies and protocols define the external interface of the base station system. For the i...
