Gateway home location register and method of exchanging subscriber routing information using the same
First Claim
1. A Gateway Home Location Register (GHLR), comprising:
- a signaling transceiving module, connected to a subscriber information storage network element in the home network and a network element capable of fetching subscriber routing information in the visited network, and designed to receive a signaling request and return an acknowledgement, so as to accomplish information exchange between the network element and the GHLR;
a security rule configuration module, designed to store intercommunication security rules and relevant data of the GHLR system;
a routing information security analysis module, designed to receive and store signaling information sent from the signaling transceiving module, to identify and analyze the signaling request according to security rules generated by the security rule configuration module, and to return the acknowledgement to a destination network element via the signaling transceiving module.

Abstract
A Gateway Home Location Register (GHLR) includes a signaling transceiving module, a security rule configuration module, and a routing information security analysis module. A method of exchanging roaming subscriber routing information includes the following steps: the GHLR in the home network receives an information request and determines the request according to the security rules in GHLR; if the request is according to the security rules in GHLR, GHLR sends called information to the network element capable of fetching subscriber routing information in the visited network. Through introducing a roaming subscriber information security control method and a device GHLR, this invention can solve the problem of exchanging roaming subscriber information between networks, support the visited network to provide service for the roaming subscribers in it, and protect security of the home operator and subscriber information.

10. A method of exchanging roaming subscriber routing information, comprising the following steps:
-
a. a network element capable of fetching subscriber routing information in the visited network sending a routing information request signaling to the GHLR in the home network; b. the GHLR receiving the information request and determining the request according to the security rules of the GHLR;
if the request is accordant to the intercommunication security rules of the GHLR, going to step c;
otherwise the GHLR rejecting the information request;c. the GHLR interacting with the HLR in the home network to obtain routing information; d. the GHLR determining the received routing information according to the intercommunication security rules;
if the routing information is accordant to the intercommunication security rules, going to step e;
otherwise the GHLR rejecting the request;e. sending the routing information to the network element that sending the request in the visited network. - View Dependent Claims (11, 12)
