Preferential inserting method for preferential insert and channel assigned user

Abstract

A method for implementing priority access of PACA users includes: makes classification for users; when the resources of wireless channel or circuit are not enough, dismantles the link of low grade user, makes priority access to the released resource for the PACA calling or called user. The method can make the PACA user no need to queue in BSC, and can meet special user' requirement.

Description

technical field [0001] The invention relates to the field of wireless communication, in particular to a method for realizing a PACA (Priority Access and Channel Assignment) user priority access system. Background technique [0002] When a mobile phone user is in charge or called, it needs to occupy wireless channel resources and ground circuit resources. Among them, the ground circuit resources are allocated by the mobile switching center MSC, and the wireless channel resources are allocated by the base station control system BSC. If the corresponding resources are not allocated, the call Unable to build. [0003] For some special users (such as high-level users in the military network), it is necessary to ensure that they can get through the phone when resources are insufficient. [0004] In the prior art, user priority access is implemented according to the protocol. [0005] When the mobile phone is the calling party and requires access, the base station control system ...

AI Technical Summary

Problems solved by technology

[0019] 1. If the mobile user who is in the call does not actively end the call, the PACA user cannot access;

[0020] 2. PACA users queue up in the base station control system BSC, waiting for other users to end the call to release resources, and the access speed is slow;

[0021] 3. Due to the complicated implementation process, there is no PACA called process in the protocol
