Allocating addresses to mobile stations
First Claim
1. A method of allocating an address to a mobile station operating in a wireless communication system in order to facilitate a communication link to a fixed communication system, the method characterised by the steps of:
- receiving an address mapping inquiry from the fixed communication system;
locating a respective terminal identifier of the mobile station in response to the supplied address mapping inquiry;
determining whether an address has been allocated for the mobile station;
activating,9 in response to a negative determination, a packet data protocol context allocation request; and

Abstract
A method of allocating an address to a mobile station operating in a wireless communication system is described in order to facilitate a communication link to a fixed communication system. The method is characterised by the steps of receiving (100) an address mapping inquiry from the fixed communication system; locating (102) a respective terminal identifier (58) of the mobile station in response to the supplied address mapping inquiry; and determining whether an address has been allocated for the mobile station. If an address has not been allocated to the mobile station, an address allocation request (112) is activated and an address corresponding to the respective terminal identifier (58) of the mobile station is allocated.

- 8. A communications system characterised by a mapping table for allocating an address to a mobile station operating in a wireless communication system in order to facilitate a communication link to a fixed communication system, wherein the mapping table maps the mobile station domain name address to a mobile station terminal number.

13. A method of mapping an internet protocol address in response to a domain name inquiry of a mobile station operating in a wireless communication system in order to facilitate a communication link from a fixed communication system, the method comprising the steps of:
-
receiving at a domain name server an address mapping inquiry from the fixed communication system relating to a domain name of the mobile station;
sending an internet protocol address inquiry by the domain name server to a gateway to determine whether an address has been allocated for the mobile station;
receiving, by the domain name server, an internet protocol address from the gateway, if an internet protocol address has previously been allocated to the mobile station associated with that domain name; and
responding to the fixed communication system with the associated internet protocol address.
