Method and computer-readable medium for managing roaming restrictions in a wireless environment
First Claim
1. A method for controlling roaming restrictions for dispatch calling of a mobile station in a network, comprising the acts of:
- receiving at a home location register of the mobile station a dispatch processor identifier identifying a dispatch application processor that supports a plurality of mobile stations for dispatch calling, and a mobile station identifier that identifies the mobile station;
determining at the home location register a domain of the dispatch application processor based upon the dispatch processor identifier by accessing data stored in the home location register which is sent to the home location register during an enhanced global title translation table tool (EGT4) distribution process;
determining at the home location register whether the mobile station is authorized to operate in the domain, based upon the mobile station identifier;
sending from the home location register to the dispatch application processor subscriber data including calling features of the mobile station which are restricted in the domain;
preventing at the dispatch application processor the mobile station from operating in the domain, if the mobile station is not authorized to operate in the domain; and
restricting at the dispatch application processor calling features available to the mobile station based on the subscriber data and the mobile station identifier, if the mobile station is authorized to operate in the domain.

Abstract
A method and computer-readable medium for controlling roaming restrictions for dispatch calling of a mobile station in a network are provided. A home location register receives a dispatch application processor identifier and a mobile station identifier. The domain in which the dispatch application processor is located may be determined by the home location register, based upon the dispatch application processor identifier. A determination can be made whether the mobile station is authorized to operate in the domain, based upon the mobile station identifier. If the mobile station is not authorized to operate in the domain, the mobile station is prevented from operating in the domain. On the other hand, if the mobile station is authorized to operate in the domain, the operation of the mobile station may be allowed, but restricted to certain predetermined calling features.
