Regulation method and system for configuration of common control channel, and base station controller

Abstract

The invention provides a regulation method and a regulation system for the configuration of a common control channel (CCCH), and a base station controller. The method, the system and the base station controller are used for solving the problem that the group call service access timeliness of a terminal user can be influenced when a small number of notification channel (NCH) blocks are configured and a great number of notices exist in a cell during the static configuration of the conventional CCCH, so that the scheduling efficiency of the notices cannot be ensured. The method comprises the following steps that: the base station controller determines the current notice number of a group call service in the cell; and when the current notice number is greater than the maximum number of notices which can be born by the NCH blocks on a current CCCH of the cell, the base station controller regulates the number of the NCH blocks on the CCCH to be greater. By using the technical scheme, the condition that a small number of NCH blocks are configured while a great number of notices exist in the cell is avoided, the terminal user can timely access the group call service, and the scheduling efficiency of the notices can be ensured.

Description

technical field [0001] The present invention relates to the field of GSM (Global System for Mobile communication, global system for mobile communication) mobile communication technology, in particular to a method, system and base station controller for adjusting common control channel configuration. Background technique [0002] Voice group call service (VGCS, Voice Group Call Service) and voice broadcast service (VBS, Voice Broadcast Service) are both multi-party language communication methods, which break through the limitations of point-to-point communication and can quickly establish calls. These two services can Collectively referred to as the group call service. [0003] The group call service includes members with two identities, that is, dispatchers and ordinary users. The dispatcher can be a fixed network user, such as a dispatching station, or a mobile user; there can be zero, one or a limited number of dispatchers in the group call service; ordinary users refer t...
