Dynamic identity association within a wireless network

1. A method of providing access to telecommunication services, comprising the steps of:

receiving a routing information request for terminating a communication with a mobile station located within a visited geographic region, the routing information request including a directory number local to the visited geographic region; and

dynamically selecting a subscriber identity associated with the received directory number from an evaluation of a decision tree, the decision tree associating a reference directory number with a plurality of reference subscriber identities, each reference subscriber identity being associated with a telecommunications service user, each user being registered to receive telecommunication services within a respective home geographic region, the home geographic region being different from the visited geographic region, the mobile station receiving access to the telecommunication services within the visited geographic region via the selected subscriber identity.

2. The method according to claim 1 , wherein the decision tree includes at least one logic rule, each said logic rule associating the reference directory number with one of the reference subscriber identities, and the step of selecting the subscriber identity comprises evaluating ones of the logic rules correlating with the received directory number.

3. The method according to claim 2 , wherein the logic rule evaluating step comprises evaluating each one logic rule in accordance with at least one of a time instant of the routing information request, the geographic region, a next available one of the subscriber identity in a list of the subscriber identities, and a membership of the user in a group.

4. A non-transitory computer-readable medium carrying computer processing instructions which, when executed by a computer, cause the computer to perform the following steps:

receive a routing information request for terminating a communication with a mobile station located within a visited geographic region, the routing information request including a directory number local to the visited geographic region; and

dynamically select a subscriber identity associated with the received directory number from an evaluation of a decision tree, the decision tree associating a reference directory number with a plurality of reference subscriber identities, each reference subscriber identity being associated with a telecommunications service user, each user being registered to receive telecommunication services within a respective home geographic region, the home geographic region being different from the visited geographic region.

5. The computer-readable medium according to claim 4 , wherein the decision tree includes at least one logic rule, each said logic rule associating the reference directory number with one of the reference subscriber identities, and the step of selecting the subscriber identity comprises evaluating ones of the logic rules correlating with the received directory number.

6. The computer-readable medium according to claim 5 , wherein the logic rule evaluating step comprises evaluating each one logic rule in accordance with at least one of a time instant of the routing information request, the geographic region, a next available one of the subscriber identity in a list of the subscriber identities, and a membership of the user in a group.
