Abstract

In one embodiment, a scheme is provided for network selection by a user equipment (UE) device that is operable to discover multiple PLMNs in a location area. Each discovered PLMN is identified and an indicium associated with the PLMN is presented to the user so that the user can select a particular PLMN.

Claims

1. A network selection method, comprising:

identifying a list of available Public Land Mobile Networks (PLMNs) discovered through scanning by a user equipment (UE) device in a location area;

presenting to a user an indicium associated with each of said available PLMNs; and

selecting a particular PLMN by said user based at least in part upon said indicium for registering therewith.

2. The network selection method as recited in claim 1, wherein said particular PLMN comprises a wide area cellular network selected from the group consisting of a General Packet Radio Service (GPRS) network, an Enhanced Data Rates for Global System for Mobile Communications (GSM) Evolution (EDGE) network, a 3^rd Generation Partnership Project (3GPP)-compliant network, an Integrated Digital Enhanced Network (IDEN), a Code Division Multiple Access (CDMA) network, a Universal Mobile Telecommunications System (UMTS) network, and a Time Division Multiple Access (TDMA) network.

3. The network selection method as recited in claim 1, wherein at least a portion of said available PLMNs are discovered in a wideband scanning process effectuated by said UE device in cellular telephony bands.

4. The network selection method as recited in claim 1, wherein at least a portion of said available PLMNs are discovered in a wireless access network scanning process effectuated by said UE device.

5. The network selection method as recited in claim 4, wherein said wireless access network scanning process is effectuated in a frequency band compliant with a Wireless Local Area Network (WLAN) standard selected from the group consisting of:

IEEE 802.11b standard, IEEE 802.11a standard, IEEE 802.11g standard, HiperLan standard, HiperLan II standard, Wi-Max standard, OpenAir standard, and Bluetooth standard.

6. The network selection method as recited in claim 1, further comprising selecting a different PLMN from said available PLMNs.

7. The network selection method as recited in claim 1, wherein at least a portion of said available PLMNs are Equivalent Home PLMNs with respect to a subscriber identity associated with said UE device.

8. The network selection method as recited in claim 1, wherein each of at least a portion of said available PLMNs is identified with a combination of a Mobile Country Code (MCC) and a Mobile Network Code (MNC).

9. The network selection method as recited in claim 1, wherein each of at least a portion of said available PLMNs is identified with a System Identification (SID) parameter.

10. The network selection method as recited in claim 1, wherein said indicium comprises a unique name identifying each of said PLMNs.

11. The network selection method as recited in claim 1, wherein said indicium is presented based on a database structure provided with said UE device.

12. The network selection method as recited in claim 11, wherein said database structure is provided as a file on one of a Subscriber Identity Module (SIM) card and a Removable User Identity Module (RUIM) card operable with said UE device.

13. The network selection method as recited in claim 11, wherein said database structure is stored in a memory module integrated with said UE device.

14. The network selection method as recited in claim 1, further comprising:

determining if a discovered PLMN is a Master Home PLMN (MHPLMN); and

if so, providing to said user an indication to highlight that said discovered PLMN is an MHPLMN.

15. The network selection method as recited in claim 1, further comprising selecting a different PLMN from said available PLMNs based on comparing capabilities of said available PLMNs.

16. A user equipment (UE) device, comprising:

a communication subsystem including a transceiver module operable for scanning in a cellular band to discover available Public Land Mobile Networks (PLMNs) in a location area;

a logic module operable to identify a list of available PLMNs discovered through scanning in said cellular band; and

a logic module for presenting to a user an indicium associated with each of said PLMNs, whereby said user can select a particular PLMN based on at least in part upon said indicium.

17. The UE device as recited in claim 16, wherein said particular PLMN comprises a wide area cellular network selected from the group consisting of a General Packet Radio Service (GPRS) network, an Enhanced Data Rates for Global System for Mobile Communications (GSM) Evolution (EDGE) network, a 3^rd Generation Partnership Project (3GPP)-compliant network, an Integrated Digital Enhanced Network (IDEN), a Code Division Multiple Access (CDMA) network, a Universal Mobile Telecommunications System (UMTS) network, and a Time Division Multiple Access (TDMA) network.

18. The UE device as recited in claim 16, wherein said communication subsystem further comprises a transceiver module operable for scanning in a frequency band compliant with a wireless access network scanning process, said frequency band comprising a Wireless Local Area Network (WLAN) standard selected from the group consisting of:

IEEE 802.11b standard, IEEE 802.11a standard, IEEE 802.11g standard, HiperLan standard, HiperLan II standard, Wi-Max standard, OpenAir standard, and Bluetooth standard.

19. The UE device as recited in claim 18, wherein at least a portion of said available PLMNs are discovered in said wireless access network scanning process effectuated by said UE device.

20. The UE device as recited in claim 16, wherein said indicium comprises a unique name identifying each of said PLMNs.

21. The UE device as recited in claim 16, wherein said logic module for presenting an indicium is operable responsive to a database structure provided with said UE device.

22. The UE device as recited in claim 21, wherein said database structure is provided as a file on one of a Subscriber Identity Module (SIM) card and a Removable User Identity Module (RUIM) card operable with said UE device.

23. The UE device as recited in claim 21, wherein said database structure is stored in a memory module integrated with said UE device.

24. The UE device as recited in claim 16, further comprising a logic module for determining if a discovered PLMN is a Master Home PLMN (MHPLMN), wherein said logic module for presenting an indicium to said user includes logic for providing an indication to highlight that said discovered PLMN is an MHPLMN if so determined.

25. The UE device as recited in claim 16, further comprising a logic module for comparing capabilities of said available PLMNs, wherein said user can select a different PLMN from said available PLMNs based on said capabilities.
