In the invention the first identifier is changed (3-3) in a message to be transferred to the server to a second identifier before transferring the message to the server. Thus the message received from the network can be associated with a particular subscriber in the server. ## Claims ### Claim 1 A method, comprising: receiving a message at a node of a communications network, the message comprising a first unique subscriber identifier, wherein the first unique subscriber identifier comprises an International Mobile Subscriber Identity (IMSI) number or a Temporary Mobile Subscriber Identity (TMSI) number; distinguishing the first unique subscriber identifier from the message; searching for a subscriber identifier pair, wherein the subscriber identifier pair comprises a correlation of the first unique subscriber identifier and a second unique subscriber identifier, wherein the second unique subscriber identifier comprises a Mobile Subscriber International ISDN (MSISDN) number; including the second unique subscriber identifier in the message; and transmitting the message with the second unique subscriber identifier. ### Claim 2 (depends on 1) The method of claim 1, wherein the message is transmitted from the node to a server of a service provider. ### Claim 3 (depends on 1) The method of claim 1, wherein the message is transmitted from the node to a Wireless Application Protocol (WAP) server. ### Claim 4 (depends on 1) The method of claim 1, wherein the message further comprises an Internet Protocol (IP) address. ### Claim 5 (depends on 1) The method of claim 1, wherein the message is received from a gateway general packet radio service (GPRS) support node (GGSN). ### Claim 6 An article of manufacture including a non-transitory computer-readable medium having instructions stored thereon that, in response to being executed by a computing device, cause the computing device to perform operations comprising: receiving a message, the message comprising a first unique subscriber identifier, wherein the first unique subscriber identifier comprises an International Mobile Subscriber Identity (IMSI) number or a Temporary Mobile Subscriber Identity (TMSI) number; distinguishing the first unique subscriber identifier from the message; searching for a subscriber identifier pair, wherein the subscriber identifier pair comprises a correlation of the first unique subscriber identifier and a second unique subscriber identifier, wherein the second unique subscriber identifier comprises a Mobile Subscriber International ISDN (MSISDN) number; including the second unique subscriber identifier in the message; and transmitting the message with the second unique subscriber identifier. ### Claim 7 (depends on 6) The article of manufacture of claim 6, wherein the message is transmitted from the node to a server of a service provider. ### Claim 8 (depends on 6) The article of manufacture of claim 6, wherein the message is transmitted from the node to a Wireless Application Protocol (WAP) server. ### Claim 9 (depends on 6) The article of manufacture of claim 6, wherein the message further comprises an Internet Protocol (IP) address. ### Claim 10 (depends on 6) The article of manufacture of claim 6, wherein the message is received from a gateway general packet radio service (GPRS) support node (GGSN). ### Claim 11 A method, comprising: receiving a message at a first node of a communications network, the message comprising a first unique subscriber identifier, wherein the first unique subscriber identifier comprises an International Mobile Subscriber Identity (IMSI) number or a Temporary Mobile Subscriber Identity (TMSI) number; sending a request message from the first node to a second node of the communications network, the request message comprising at least the first unique subscriber identifier; receiving, at the first node, a response message comprising a second unique subscriber identifier, wherein the second unique subscriber identifier comprises a Mobile Subscriber International ISDN (MSISDN) number; distinguishing the second unique subscriber identifier from the response message; including the second unique subscriber identifier in the message; and transmitting the message with the second unique subscriber identifier. ### Claim 12 (depends on 11) The method of claim 11, wherein the message including the second unique subscriber identifier is transmitted to a server of a service provider. ### Claim 13 (depends on 12) The method of claim 12, wherein the second unique identifier is a default value MSISDN. ### Claim 14 (depends on 13) The method of claim 13, wherein the default value MSISDN is the same for all servers. ### Claim 15 (depends on 13) The method of claim 13, wherein the default value MSISDN is specific to the server. ### Claim 16 (depends on 12) The method of claim 12, wherein the request message comprises data about the server. ### Claim 17 (depends on 11) The method of claim 11, wherein the request message comprises data about a service for which the second unique subscriber identifier is requested. ### Claim 18 An article of manufacture including a non-transitory computer-readable medium having instructions stored thereon that, in response to being executed by a computing device, cause the computing device to perform operations comprising: receiving a message, the message comprising a first unique subscriber identifier, wherein the first unique subscriber identifier comprises an International Mobile Subscriber Identity (IMSI) number or a Temporary Mobile Subscriber Identity (TMSI) number; sending a request message to a second node of the communications network, the request message comprising at least the first unique subscriber identifier; receiving a response message comprising a second unique subscriber identifier, wherein the second unique subscriber identifier comprises a Mobile Subscriber International ISDN (MSISDN) number; distinguishing the second unique subscriber identifier from the response message; including the second unique subscriber identifier in the message; and transmitting the message with the second unique subscriber identifier. ### Claim 19 (depends on 18) The article of manufacture of claim 18, wherein the message including the second unique subscriber identifier is transmitted to a server. ### Claim 20 (depends on 19) The article of manufacture of claim 19, wherein the second unique identifier is a default value MSISDN. ### Claim 21 (depends on 20) The article of manufacture of claim 20, wherein the default value MSISDN is the same for all servers. ### Claim 22 (depends on 20) The article of manufacture of claim 20, wherein the default value MSISDN is specific to the server. ### Claim 23 (depends on 19) The article of manufacture of claim 19, wherein the request message comprises data about the server. ### Claim 24 (depends on 18) The article of manufacture of claim 18, wherein the request message comprises data about a service for which the second unique subscriber identifier is requested.
