Problems solved by technology

[0008] In practical applications, there are the following problems: when the Iub interface adopts E1 / T1 transmission end-to-end, the transmission efficiency is very low
[0009] The main reason for this situation is that when ATM and IP technologies were first developed, the bandwidth of the bearer network was considered to be large enough, and the main focus of development was the forwarding rate rather than the transmission efficiency, so the transmission efficiency of ATM and IP was relatively low
However, when Node B and RNC use E1 / T1 to transmit end-to-end large-bandwidth service data, since the E1 / T1 bandwidth is not large, the transmission cost per bit is relatively high, so the large-bandwidth NodeB and RNC The data business between them is not economical
For operators, this transmission method is not suitable for reducing the number of E1 / T1 used for transmission in the WCDMA network, so it cannot reduce construction costs and maintenance costs, and cannot guarantee the profitability of operators

Embodiment Construction

[0040] In order to make the object, technical solution and advantages of the present invention clearer, the present invention will be further described in detail below in conjunction with the accompanying drawings.

[0041] The core of the present invention is that if the source node sends a data frame adapted by the direct adaptation layer (D-AL), then the IP address and the UDP port number of the target node are mapped to the node number of the target node, and the node number is used in the The lower layer of the IP layer encapsulates and sends the data frame, and the target node finds the corresponding IP address and UDP port number according to the node number of the received data frame, and completes the reception of the data frame. If the source node sends a data frame adapted by the multiplexing adaptation layer (MUX-AL), the IP address and UDP port number of the target node are mapped to the node number and the multiplexing microframe port number of the target node, an...

Abstract

The invention is used for improving the transmission efficiency of Iub interface and uses SDTP protocol to make data transmission of Iub interface. For each FP layer connection, the bottom layer needs to provide two links; when the length of FP frame is less than M bytes, one of said links maps the IP address and UDP port number to the SDTP node number and MUX-AL port number; when the length of FP frame is more than M bytes, another link directly uses IP address and UDP to package and adopt D-AL to bear.

Description

technical field [0001] The invention relates to the field of mobile communication, in particular to the Iub interface data transmission technology in the mobile communication network. Background technique [0002] Wideband Code Division Multiple Access ("WCDMA") is one of the three mainstream standards of the third generation mobile communication (the 3rd Generation, "3G"). It inherits the existing global mobile communication The system (Global Systems for Mobile communications, referred to as "GSM") features a high degree of standardization and good openness, and has good compatibility and interoperability with the GSM network. It is one of the development trends of mobile communications in the future. [0003] In a WCDMA system, a Radio Access Network ("RAN" for short) includes a Radio Network Controller ("RNC" for short) and a Node B (Node B) serving as a base station. Among them, each Node B is used to receive user equipment (User Equipment, referred to as "UE") signals...
