Problems solved by technology
This leads to the base station's low ability to control and schedule terminals. If too many terminals request the base station to provide services at the same time, it will cause the terminal to wait for a long time for scheduling, which will affect the user experience.

Embodiment Construction
[0069] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only some, not all, embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without creative efforts fall within the protection scope of the present invention.
[0070] The core idea of the method for allocating high-speed shared control channels provided by the present invention is that when the space position isolation between the terminal that initiates the service request and the terminal that has already occupied the non-idle high-speed shared control channel is greater than the set threshold, the base station will initiate a service request. The terminal allocates a non-idle high-speed shared control channel, so that...

The invention discloses a method for distributing a high-speed shared control channel. The method comprises the following steps of: (A) receiving a service request from a terminal by a base station; (B) acquiring the space position information of the terminal according to the service request by the base station; and (C) judging whether the space position isolation degree of the terminal and a terminal occupying a non-idle high-speed shared control channel is larger than a set threshold value or not according to the space position information of the terminal by the base station and distributing the non-idle high-speed shared control channel for the terminal if the space position isolation degree of the terminal and the terminal occupying a non-idle high-speed shared control channel is larger than the set threshold value. In the invention, at least two terminals with the mutual space position isolation degree larger than the set threshold value can be simultaneously controlled and scheduled by the base station using the same high-speed shared control channel, and the capability of the base station for controlling and scheduling terminals is enhanced.
Description
technical field [0001] The present invention relates to the field of communication technology, in particular to a method, system and device for allocating high-speed shared control channels. Background technique [0002] In the existing TDD-HSDPA (Time Division Duplex High Speed Data Packet Access, Time Division Duplex High Speed Downlink Data Packet Access) technology, the RNC (Radio Network Controller, radio network controller) allocates up to 4 HS-SCCHs to each base station at the same time (HighSpeed Shared Control Channel, high-speed shared control channel), each high-speed shared control channel occupies a spread spectrum code channel, and the 4 high-speed shared control channels use 4 different spread spectrum code channels to transmit control data. Each high-speed shared control channel is divided into a downlink control channel and an uplink control channel by time-division duplex technology, and the downlink control channel and the uplink control channel use ...
