Embodiment Construction

[0033] For a distributed cellular wireless communication system, the wireless access point providing services is a cell. In order to ensure that the terminal can use the wireless resources of the cell, including parameters such as frequency points and common channels, the cell will repeatedly broadcast related information such as wireless parameters in system broadcast messages. After receiving the system broadcast message, the terminal can also know the settings of the wireless parameters of the cell, and then initiate a call according to these settings.

[0034] The present invention uses the following method to allow the terminal to know the openness of the private cell without going through the access attempt process:

[0035] 1) Change the system broadcast message and add information elements to indicate the openness of private cells. Like other information elements in the system broadcast message, this information element is broadcast throughout the coverage area of ​​t...

Abstract

The invention provides a method of improving the private cell access control, comprising, (a) adding cell expressing the private cell openness degree in the system broadcast message; (b) when sending the system broadcast message in the private cell, filling in the private cell openness degree cell to indicate the openness degree of the private cell; (c) when the terminal chooses the cell, judging whether to access in the cell according to the cell openness degree in the system broadcast message. The invention further provides a base station, comprising a cell openness degree controlling module for receiving the command of the user to the cell openness degree and obtaining the setting of the cell openness degree; a cell openness degree converting module for receiving the cell openness degree setting of the cell openness degree controlling module and converting into the data format of the cell openness degree cell in the system broadcast message and transmitting the converted data to the system message broadcast control module.

Description

technical field [0001] The invention relates to a distributed cellular wireless communication system, in particular to a method for improving access control of a private cell and a corresponding base station. Background technique [0002] The distributed cellular wireless communication system is mainly composed of terminals, base stations and core network (CN) (see figure 1 ), there may also be a base station controller or a distributed network controller between the base station and the core network (see figure 2 ), used to manage the base station and aggregate the connection between the base station and the core network. The network composed of base stations and network controllers is called the radio access network (RAN), which is responsible for access layer affairs, such as the management of radio resources. Each base station or network controller can be connected to one or more core networks. The core network is responsible for non-access stratum affairs, such as m...
