Problems solved by technology

[0007] The purpose of the present invention is to provide a connection identification configuration method to overcome the complex signaling generated by the repeated negotiation process due to the need to re-allocate the connection identification during the conversion process of the existing relay station's home cell, which leads to the disconnection between the entire cell and the terminal. Increased delay time caused by excessive signaling overhead, quality degradation and increased probability of dropped calls

Embodiment Construction

[0032] The core of the present invention is to provide a connection identification configuration method. During specific implementation, the cells that have affiliation relationship with the same relay station are set as an associated cell set, and a public connection identification group is allocated for the associated cell set, and the network side notifies the target cell to reserve the connection identification in the public connection identification group, and the relay station The terminal uses the same connection identifier in the connection identifier group before and after the attribution relationship conversion.

[0033] Those skilled in the art know that a relay station (Relay Station, RS) technology is proposed in 802.16j. The terminal communicates with the cell through the relay station, which can enhance the coverage of the cell and increase the capacity. For the terminal, the transmission power can be reduced, and the influence of the shadow effect can be reduce...

Abstract

A configuring method of connecting identification is disclosed in the present invention, in Wimax, a network side and a cell having ascription relation with a relay station configure as relating cell set, and configuring the connecting identification group to the relay station, a terminal uses the connecting identification of the connecting identification group by a cell communication between the relay station and the relating cell set, comprising steps: the network side informs a target cell of the relay station ascription change to obligate the connecting identification group, wherein the target cell is in the relating cell set; the relay station ascription change generating, the source cell releases the connecting identification between terminals; the terminal uses the same connecting identification of the obligated connecting identification group to communicate with the target cell. Using the present invention can avoid signaling mutual generated by arranging course in redistributing connecting identification course, thereby implementing predigestion of signaling in the relay station ascription change course, furthermore reducing delay time, promoting the service quality, and decreasing the dropping rate.

Description

technical field [0001] The invention relates to the technical field of wireless communication, in particular to a method for configuring a connection identifier. Background technique [0002] In recent years, with the rapid development of communication technology, the World Interoperability for Microwave Access (Wimax) based on the Institute of Electrical and Electronics Engineers (Institute of Electrical and Electronics Engineers, IEEE) 802.16 standard has become an extremely Hot technology with strong competitiveness. Wimax is a Wireless Metropolitan Area Network (WMAN) technology, and it is a new air interface standard proposed for microwave and millimeter wave bands. Wimax has the advantages of high spectrum utilization, wide coverage and high data rate. More importantly, Wimax combines the bandwidth advantages of traditional broadband based on cable access and the flexibility and mobility of wireless access, and can also provide various services that can meet high qua...
