Problems solved by technology

[0012] Establishing RSCH branches for wireless terminals in the soft handover area according to the strength of the forward pilot does not guarantee the channel quality of the established RSCH branches. The established RSCH branches may have low quality, high bit error rate and low transmission performance.
When the RSCH supports soft handover, the established RSCH branch with poor channel quality is added to the RSCH active set. The wireless terminal not only cannot obtain the soft handover gain, but also wastes system resources; when the RSCH does not support soft handover, only one RSCH is allowed When branching, the established RSCH with poor channel quality will affect the reverse data transmission of the wireless terminal

Embodiment Construction

[0030] In order to make the objectives, technical solutions and advantages of the present invention clearer, the present invention will be described in further detail below with reference to the accompanying drawings and specific embodiments.

[0031] In the present invention, in order to establish an RSCH branch with good channel quality for the wireless terminal in the soft handover area, the parameter that can truly reflect the channel quality from the wireless terminal to the BTS branch in the FCH active set is used as the basis for establishing the RSCH branch. The pilot strength, the reference pilot or the combined strength value of the reverse pilot strength and the forward pilot strength is used as the basis for establishing the RSCH branch.

[0032] The present invention is described below by taking the reverse pilot strength as the basis for establishing the RSCH branch for the wireless terminal in the soft handover area as an example.

Abstract

The present invention discloses establishing reversal supply channel RSCH branchy method. Said method includes A, more than one BTS measuring to obtain parameter, said parameter reflecting fundamental channel FCH centralizing from wireless terminal to BTS branchy channel quality, transmitting said parameter to base station controller BSC; B, BSC according to received parameter size activating concentric from wireless terminal to BTS branch to FCH to make sorting from high to low, selecting sorting highest one or more than one FCH activating concentric from wireless terminal to BTS branch used as said wireless terminal established RSCH branch. Said method ensures in soft switching zone wireless terminal established RSCH branchy channel quality.

Description

technical field [0001] The present invention relates to a technology for establishing a reverse supplemental channel (RSCH) in a wireless communication system, and more particularly, to a method for establishing an RSCH branch in a soft handover area. Background technique [0002] In wireless communication systems, such as Code Division Multiple Access (CDMA), reverse data for data traffic is transmitted on the RSCH. When the wireless terminal is in the soft handover area, because the wireless environment changes drastically, one or more RSCH branches need to be established according to the wireless environment and allocated to the wireless terminal to transmit reverse data. The established RSCH branch must be able to overcome the wireless environment in the soft handover area. The impact of environmental changes on wireless terminal calls, while the wireless terminal can obtain soft handover gain. The existing protocol stipulates that the RSCH branch should be attached to ...
