Abstract

Disclosed is a method for controlling a PACA call in a mobile telecommunications system, which comprises: sending a new origination message from a mobile station in a PACA state to a base station; sending a service request message for a PACA call from the base station to a mobile switching center, requesting from the mobile switching center the base station to assign a traffic channel to the mobile station; assigning an available traffic channel to the mobile station to start a communication; and distinguishing the PACA call service from an ordinary call service.

Claims

1. A method for controlling a priority access and channel assignment (PACA) call in a mobile telecommunication system, the method comprising:

determining whether a subscriber'"'"'s registered location of an origination message agrees with the subscriber'"'"'s registered location in a visitor location register (VLR);

determining whether a mobile station is in a PACA state if the subscriber'"'"'s registered location of the origination message agrees with that registered in the VLR;

determining whether a cell ID of the origination message agrees with that registered in the VLR if the mobile station is in the PACA state;

determining that the mobile station has sent a new origination message in the PACA state if the cell ID of the origination message agrees with that registered in the VLR;

sending a PACA call update message to a base station; and

deleting PACA call information for the mobile station from the base station.

2. A method as defined in claim 1, wherein the PACA call information deleted from the base station is previously stored in a PACA call buffer of the base station.
