Problems solved by technology

However, as some functional entities of the RNC move down to the NodeB, the demand for direct communication between the NodeBs will increase. For example, the fast cell selection (FCS) of the high-speed downlink packet access (HSDPA) replaces the centralized PDU queue in the RNC with a distributed PDU queue. Type PDU queue, the synchronization information of the PDU queue is frequently transmitted between NodeBs
It can be seen that with the gradual transfer of RNC functions to NodeB, the control relationship between RNC and NodeB is also reduced, and the process control between UTRAN entities is gradually shifting from centralized management to distributed management. If the current information exchange between NodeBs is still It is completed by RNC, not only the transmission path becomes longer, but also is still restricted by the delay of the Iub / Iur interface, which will inevitably lead to a decrease in system efficiency

Embodiment Construction

[0020] The present invention will be described in further detail below in conjunction with the accompanying drawings.

[0021] In the UTRAN system, in order to reduce the burden of RNC data processing and move the function of RNC to the base station, the present invention establishes a logical interface between the physical base station and the base station in UTRAN--IuNB, which can realize the interconnection of base stations. figure 2 . Reference to the embodiment of the method for realizing direct communication between base stations in the present invention based on the above-mentioned interface image 3 . The first step is to establish the logical interface IuNB for the interconnection between base stations. The following principles should be followed: first, the interface should be an open interface; second, the interface should support signaling and data transmission between two base stations; third, the interface should be It is a point-to-point logical connection in...

Abstract

A method to realize the direct communication on data and signalling between the base stations includes the logic interface IuNB used for interconnections between the base stations and its supporting on the transmission of data and signalling between two base stations as well as fulfilling the management and maintenance of transmission network, business management of transmission channel and interface resources between the base stations, setting up the logic link between two base stations through above-mentioned interface and using it for finishing the transmission and management function of data and signalling, releasing the logic link between the base stations at last, and the said method also establishing the protocol stack between the control face of abovesaid IuNB interface and user face.

Description

technical field [0001] The invention relates to the transmission technology of the wireless communication network, and specifically proposes a method for realizing direct communication of data and signaling between base stations of the wireless communication system. Background technique [0002] In the Universal Terrestrial Radio Access Network (UTRAN) system, entities of different nodes adopt different interfaces applying different protocols due to different functions to be completed and data to be processed. For example, the interface between the radio network controller (RNC) and SGSN / MSC (GPRS service support node / mobile switching center) is an Iu interface, and the interface control protocol is RNAP (radio network application part); the interface between RNC and RNC It is the RNC interface (Iur) interface in UTRAN, and the interface control protocol is Radio Network Subsystem Application Part (RNSAP); the interface between RNC and the base station (NodeB) is the interfa...
