Gateway location register

摘要

A Gateway Location Register (GLR) for a Public Land Mobile Network (PLMN) stores information relating to each Mobile Subscriber (MS) roaming in the PLMN. The GLR may receive a request from an associated visitor registration entity of the PLMN relating to one MS and, in response, perform an action based on the stored information relating to a plurality of MS. Additionally or alternatively, the GLR selects at least one MS currently roaming in the PLMN and performs an action for at least one selected MS. The action may comprise sending a message to a visitor registration entity of the PLMN associated with each selected MS or be performed in response to a request received from an associated visitor registration entity of the PLMN in respect of a selected MS.
