Embodiment Construction

[0026]The present invention will be described in detail below with reference to the accompanying drawings and specific embodiments:

[0027]The created linked list is used to record information in the rail communication network, ensuring that the same time can be simultaneously seen at the same time, multiple calls, and multiple broadcast calls.

[0028]The information of each call of the communication terminal is documented into an element record in a linked list array, and the single state control of the communication terminal is replaced by controlling the control of each element in the linom list.

[0029]Such asFigures 2 to 4As shown, the linked list array can be split into the Free group and the USED group, which is used to express the calls not performed in the current network using the Free group, and expose the calls related to the communication terminal in the current network in the current network.

[0030]Suitable for current railways widely adopted GSM-R communication networks.

Abstract

The invention relates to a call management method in a railway communication network, belonging to the field of railway communication. A method for multi-call management in a railway communication network, characterized in that: the established linked list array is used to record the information of point calls, group calls and broadcasts in the railway communication network, so as to ensure that single point calls and multiple calls can be seen at the same time. For group calls and multiple broadcast incoming calls, the call information of the communication terminal is converted into elements and recorded in the linked list array. By controlling each element in the linked list array instead of the single state control of the communication terminal, the linked list array can be split They are free group and used group. The free group is used to describe the calls not in progress in the current network, and the used group is used to represent the ongoing calls related to communication terminals in the current network. It is applicable to the GSM‑R communication network. The invention prevents the communication terminal from missing any incoming call during normal conversation, and improves the use efficiency of the communication terminal.

Description

Technical field[0001]The present invention relates to a call management method in a railway communication network, and more particularly to a method of multi-call management in a railway communication network.Background technique[0002]The GSM-R network is a comprehensive private digital mobile communication system designed for railway communications. It is a special mobile communication. It is widely used in railway regions, mainly providing wireless columns, group transfer communication, and segment maintenance and maintenance operations. , Emergency communication, tunnel communication and other voice communication functions are very effective dispatch communication tools. The GSM-R network will introduce the concept of group calls and broadcasts in the public domain without incorporating group calls and broadcasts in the public network system, and the implementation of group call / broadcast in the protocol is different from traditional distortion differences. Large, leading to th...
