Apparatus, and associated method, for facilitating WLAN selection by a mobile node
View Patent ↗Apparatus, and an associated method, by which to facilitate selection of a WLAN through which a mobile node communicates. Selection takes into account the geographic positioning of the mobile node. The mobile node ascertains its geographic positioning by monitoring cellular-positioning signals. And, availability of WLANs through which to communicate is ascertained by detecting signals broadcast by the WLANs.
1. A user equipment configured to select a wireless network of a first type to communicate through, the user equipment comprising:
a receiver configured to receive a network identifier that contains information that identifies geographical location of a network of a second type of wireless network, the information including a country code and a network code sent by the network of the second type of wireless networks;
a first list of a plurality of wireless networks of the first type, the first list having indicia identifying each of the first type of wireless networks and having information that identifies the geographical location of each wireless network in the list, each wireless network contained in the first list having a corresponding selection criteria attribute, the attribute categorizes the first list and each wireless network contained in the first list with a common preference; and
a selector coupled to receive a network identifier of a network of a first type of wireless network and coupled to said receiver to receive an indication of the network identifier received at said receiver, the selector configured to select a network of the first type of wireless networks through which to communicate, selection made of a network by comparing the information identifying geographic information received by said receiver and the network identifier received by said selector with the indicia identifying the first wireless networks and associated information identifying geographical location in the first list.
2. The user equipment of claim 1 wherein said first list comprises a home wireless network list, and wherein each wireless network of the first type contained in said first list is associated with a mobile-node home network.
3. The user equipment of claim 1 wherein said first list further comprises a plurality of first lists, each first list associated with a different location.
4. The user equipment of claim 1 further comprising a second list of a plurality of wireless networks of the first type, the first list having indicia identifying each of the first type of wireless networks and having information that identifies the geographical location of each wireless network in the list, each wireless network contained in the list having a corresponding selection criteria attribute.
5. The user equipment of claim 4 wherein said second list comprises a preferred wireless network list, and wherein each wireless network of the first type contained in said preferred list comprises a preferred network.
6. The user equipment of claim 4 wherein said second list further comprises a plurality of second lists, each second list associated with a different location.
7. The user equipment of claim 1 further comprising a third list of a plurality of wireless networks of the first type, the third list having indicia identifying each of the first type of wireless networks and having information that identifies the geographical location of each wireless network in the list, each wireless network contained in the third list having a corresponding selection criteria attribute.
8. The user equipment of claim 7 wherein said third list comprises a neutral wireless network list, and wherein each wireless network of the third type contained in said neutral list comprises a neutral network.
9. The user equipment of claim 7 wherein said third list further comprises a plurality of third lists, each third list associated with a different location.
10. The user equipment of claim 1 wherein the wireless networks of the first type comprise wireless local area networks and wherein the information that identifies the geographical location comprises a service set identifier.
11. A method for facilitating selection at a user equipment of a wireless network of a first type through which user equipment communicates, said method comprising:
receiving at the user equipment a network identifier that contains location information including a country code and a network code sent by a network of a second type of wireless networks;
forming a first list at the user equipment of a plurality of wireless networks of the first type, the first list having indicia identifying each of the first type of wireless networks and having information that identifies the geographical location of each wireless network in the list, each wireless network contained in the first list having a corresponding selection criteria attribute, the attribute categorizes the first list and each wireless network contained in the first list with a common preference;
receiving a network identifier of a network of a first type of wireless networks; and
selecting a network of the first type of wireless networks through which to communicate, selection made of a network by comparing the network identifier containing location information and the network identifier of the network of the first type with the indicia identifying the first wireless networks and associated information identifying geographical location in the first list.
12. The method of claim 11 wherein the first list formed during said forming comprises a home wireless network list, and wherein each wireless network of the first type contained in said first list is associated with a mobile-node home network.
13. The method of claim 11 further comprising forming a second list of a plurality of wireless networks of the first type, the first list having indicia identifying each of the first type of wireless networks and having information that identifies the geographical location of each wireless network in the list, each wireless network contained in the list having a corresponding selection criteria attribute.
14. The method of claim 13 wherein the second list comprises a preferred wireless network list, and wherein each wireless network of the first type contained in the preferred list comprises a preferred network.
15. The method of claim 11 further comprising forming a third list of a plurality of wireless networks of the first type, the third list having indicia identifying each of the first type of wireless networks and having information that identifies the geographical location of each wireless network in the third list, each wireless network contained in the third list having a corresponding selection criteria attribute.
