Method and system for providing telecommunication services across networks that use different protocols
First Claim
1. A mobile communications method that comprises:
- receiving a message from a wireless communication network (“
serving network”
) indicating that a mobile communication device user has requested registration at the serving network;
storing in a database an indication that the mobile communication device user is registered in the serving network;
determining whether the mobile communication device user should be registered in only one network; and
in response to determining that the mobile communication device user should be registered in only one network, sending a message to a wireless communication network where the mobile communication device user was previously registered (“
previous network”
) that the mobile communication device user is no longer registered at the previous network.

Abstract
A method and system provide seamless, wireless telecommunication service to customers that move between disparate networks that use different protocols. A Universal Location Service Register (ULSR) communicates and provides mobility management and authentication functions across networks that use different protocols. Instead of associating each MSC with an HLR and an AuC that uses the same messaging protocol as the MSC, each MSC communicates with the ULSR for user information. The ULSR communicates with the MSCs in each network serviced by the ULSR in accordance with the protocol of that network. The ULSR stores user profiles that may include the identity of the user, authentication information for the user'"'"'s mobile phone, a list of networks the user is authorized to access, and the identity of the MSC at which the user is currently registered.

4. A mobile communications provision method in a mobile communications system having at least two wireless networks with different mobile switching center (“
- MSC”
) communication protocols, the MSCs in each wireless network being coupled to a universal location service register (ULSR) having a database of information about all subscribers registered in one or more of the wireless networks, wherein the method comprises;
tracking for each registered subscriber in the database at least one MSC where that registered subscriber is registered (“
a serving MSC”
);
receiving a routing number request associated with a registered subscriber; and
providing a routing number in response to the routing number request. - View Dependent Claims (5, 6, 7, 8)

9. A mobile communications provision method in a mobile communications system having at least two wireless networks with different mobile switching center (“
- MSC”
) communication protocols, the MSCs in each wireless network being coupled to a universal location service register (ULSR) having a database of information about all subscribers registered in one or more of the wireless networks, wherein the method comprises;
receiving from a MSC a registration request associated with a subscriber;
retrieving a user profile for the subscriber;
refusing the registration request if the user profile indicates that the subscriber is not authorized to register with the MSC; and
sending the user profile to the MSC if the user profile indicates that the subscriber is authorized to register with the MSC. - View Dependent Claims (10, 11)

12. A mobile communications system that comprises:
-
a set of wireless networks each having at least one mobile switching center (“
MSC”
), wherein at least one wireless network in the set employs a MSC communication protocol that differs from a MSC communication protocol employed by at least one other wireless network in the set;
a universal location service register (“
ULSR”
) coupled to the MSCs in each wireless network of the set, the ULSR including;
a database of information about all subscribers registered in one or more of the wireless networks in the set. - View Dependent Claims (13, 14, 15, 16, 17, 18, 19)
