Methods And Apparatus For Providing Manual Selection Of A Communication Network For A Mobile Station

Abstract

Techniques in a mobile station for use in manually selecting a communication network are described. The mobile station receives a user input for initiating a procedure for manual network selection. The mobile station identifies a plurality of communication networks available for communications by receiving, from each available network, a Mobile Country Code (MCC) and a Mobile Network Code (MNC). The mobile station retrieves from a Subscriber Identity Module (SIM) a plurality of network names identified by a plurality of address pointers corresponding to the identified available networks, where the plurality of address pointers are stored in a first file of the SIM and the plurality of network names are stored in a second file of the SIM. The mobile station then displays the plurality of network names for manual network selection.

         11 . The method of  claim 1 , wherein displaying the plurality of network names for manual network selection further comprises displaying the plurality of network names in a list. 
     
     
         12 . The method of  claim 1 , further comprising:
 displaying a prompt to manually select one of the plurality of network names being displayed.   
     
     
         13 . A mobile station comprising a processor configured to:
 receive a user input for initiating a procedure for manual network selection;   identify a plurality of communication networks available for communications by receiving, from each available network, a Mobile Country Code (MCC) and a Mobile Network Code (MNC);   retrieve from a Subscriber Identity Module (SIM) a plurality of network names identified by a plurality of address pointers corresponding to the identified available networks, the plurality of address pointers being stored in a first file of the SIM and the plurality of network names being stored in a second file of the SIM; and   display the plurality of network names for manual network selection.   
     
     
         14 . The mobile station of  claim 13 , wherein each one of the plurality of address pointers stored in the first SIM file comprises an MCC and an MNC. 
     
     
         15 . The mobile station of  claim 14 , wherein the plurality of address pointers stored in the first SIM file is used to identify the plurality of names which are retrieved from the second SIM file. 
     
     
         16 . The mobile station of  claim 14 , wherein the processor is further configured to further receive from each identified available network, a Location Area Code (LAC). 
     
     
         17 . The mobile station of  claim 14 , wherein the processor is further configured to identify a plurality of available communication networks by receiving, from each identified available network, the MCC, the MNC, and a Location Area Code (LAC). 
     
     
         18 . The mobile station of  claim 17 , wherein the processor is further configured to retrieve each network name based on the MCC, the MNC, and the LAC associated with an identified available network.
