Embodiment Construction

[0019] Embodiments of the present invention will be described in detail below with reference to the accompanying drawings.

[0020] FIG. 1 is a block diagram showing a schematic configuration of a mobile communication system according to an embodiment of the present invention. FIG. 1 shows a mobile communication system in which the communication method is PHS (Personal Handyphone System: Personal Handyphone System).

[0021] The base station controllers 10 - 1 to 10 - 4 are connected to each other via an IP (Internet Protocol, Internet Protocol) network 12 . The base station control devices 10-1 to 10-4 and the IP network 12 form a mobile communication network for exchanging control information, voice, and data. The base station controller 10-1 accommodates mobile terminals (PS: Personal Station, personal station) PS1 to PS3 such as a PHS terminal, and base stations (CS: Cell Station, cell station) CS1 to CS3.

[0022] In this embodiment, the base station control device 10-1...

Abstract

A mobile communication system which can prevent deterioration of a utilization ratio of a radio channel and degradation of communication quality is provided. The mobile communication system has a mobile terminal, base station, and a base station controller. The mobile terminal issues a link channel establishment request in order to communicate with another mobile terminal. The base station receives the link channel establishment request, and outputs a radio channel assignment request. When the base station controller receives the radio channel assignment request, the base station controller assigns the base station a radio channel which is not used in the base station and its adjacent base station and outputs a radio channel assignment answer. When the base station receives the radio channel assignment answer, the base station returns a link channel assignment answer to the mobile terminal, and establishes a communication connection with the mobile terminal by an assigned radio channel.

Description

[0001] This application is based on and claims priority from Japanese Priority Patent Application No. 2008-012821 filed on January 23, 2008, the entire contents of which are hereby incorporated by reference. technical field [0002] The present invention relates to a mobile communication system that communicates with a mobile terminal that has sent a link channel establishment request, a base station control device, a base station, and a communication connection method used in the mobile communication system. Background technique [0003] Generally, a mobile communication system has a mobile terminal that sends a link channel establishment request for a communication connection and a plurality of base stations that form a communication connection with the mobile terminal. A conventional base station has a radio channel allocation unit. When the base station receives a link channel establishment request from the mobile terminal, the base station arbitrarily allocates a wirele...
