Patent number: 6801781Abstract: A mobile communications system includes a system controller that provides access control for mobile stations within the network controlled, by the system controller. In one example, the mobile communications network is a General Packet Radio Service (GPRS) network. The system controller provides access to a packet-based data network. In addition, the system controller enables prepaid short message service (SMS), in which mobile stations can originate or receive short messages according to the prepaid SMS. A flag kept in a home location register (HLR) stores a field to indicate if the user has subscribed to prepaid SMS. In one embodiment, the field is an access point name (APN) field according to the General Packet Radio Service (GPRS) protocol.Type: GrantFiled: October 31, 2000Date of Patent: October 5, 2004Assignee: Nortel Networks LimitedInventors: Curtis M. Provost, Jerry L. Mizell, Donald B. Keeler

Patent number: 6731617Abstract: Disclosed is an apparatus providing minimal systems alterations in non-GSM cellular systems wishing to incorporate GSM GPRS messaging capability. This is accomplished by giving a registering terminal or MS an IP address for use in receiving both signaling and traffic data messages rather than using the SGSN as the traffic receiving entity and forwarding traffic to the MS from the SGSN and requiring signaling messages to be transmitted from the MSC to the MS by other means. This approach simplifies the integration of GPRS capability into any non-GSM configuration cellular system by providing a generic way to exchange signaling information between any MSC, having a known IP address, and any MS with an assigned IP address.Type: GrantFiled: July 16, 1999Date of Patent: May 4, 2004Assignee: Nortel Networks LimitedInventors: Jerry L. Mizell, Cecil L. Taylor, Mark E. Hanson

Patent number: 6201965Abstract: A system and method for facilitating a telecommunication subscriber connection using a domain name system is disclosed. The system, which is part of a DNS server, supports connection to a mobile terminal through a data network and includes multiple connections to external devices or systems, although one or more of the connections may be serviced by a single link. The connections link the system to the data network, to a home location register (“HLR”) associated with the terminal and to a mobile switch associated with the terminal. Upon initiation of a query to the DNS server through the PDN, the DNS server signals the HLR for the identification of the switch that is associated with the mobile terminal. The HLR returns an identifier for the switch and the DNS server then requests the switch to provide an address for the mobile terminal. The switch establishes a connection with the mobile terminal and provides a temporary address through a network interface system such as an interworking function.Type: GrantFiled: November 10, 1998Date of Patent: March 13, 2001Assignee: Nortel Networks LimitedInventors: Jerry L.
