Method and system for selecting a communication network

摘要

A method and system for selecting a communication network by a wireless communication device (106) includes receiving (310) an identification parameter at the wireless communication device from a communication network which identifies the communication network. Next, the method compares (312) the identification parameter with a list at the wireless communication device to determine (314) service information. The service information identifies the services supported by the communication network. The method further includes comparing (316) the service information with a service-related datum at the wireless communication device that indicates the services desired by the wireless communication device. Lastly, the method includes selecting (318) the communication network for accessing a requested service if the service information matches the service-related datum.

1. A method for selecting a communication network by a wireless communication device, the method comprising:
scanning a channel corresponding to a communication network; receiving an identification parameter at the wireless communication device from the communication network, wherein the identification parameter identifies the communication network; comparing the identification parameter with a list at the wireless communication device, wherein the list is an augmented preferred roaming list (PRL) comprising: a channel frequency, a system identification parameter, a priority of the communication network, at least one service information type, and at least one service information sub-type associated with the service information type, wherein the at least one service information type indicates at least one major type of service provided by the communication network and the at least one service information sub-type indicates at least one particular service provided by the communication network; determining, from the list and the identification parameter, a service information type and a service information sub-type associated with the service information; comparing the service information type and the service information sub-type with a service-related datum stored at the wireless communication device in a Number Assignment Module (NAM) of the wireless communication device, wherein the service-related datum indicates a service that the wireless communication device is attempting to access; and selecting the communication network for accessing a service associated with the service information type if the service information sub-type matches the service-related datum.
