Abstract

A system that provisions a multimode mobile or converged device with local time information and network provider identification when the multimode mobile device is operating within the purview of a wireless local area network (WLAN). The system includes components that receive protocol data and that extract network provider identification from the received protocol data as well as utilizing the received protocol data to ascertain the local time.

Claims

1. A method for ascertaining and displaying time zone information and a local time, comprising:

receiving protocol data from a setup server and a multimode device;

extracting location information from the protocol data;

determining a time zone based on the location information; and

generating the local time based on the time zone.

2. The method of claim 1, further comprising:

displaying the generated local time on an interface associated with the multimode mobile device.

3. The method of claim 1, wherein the receiving comprises obtaining the protocol data from a Dynamic Host Configuration Protocol (DHCP) service.

4. The method of claim 1, wherein the receiving comprises obtaining the protocol data from a Network Time Protocol (NTP) service.

5. The method of claim 1, wherein the receiving comprises obtaining the protocol data from a Session Initiation Protocol (SIP) service.

6. The method of claim 1, wherein the receiving comprises obtaining the protocol data from an Extensible Authentication Protocol (EAP) service.

7. A method for providing a multimode mobile device with a local time and a network identification, comprising:

receiving first protocol data and second protocol data;

extracting the network identification from the first protocol data substantially when the multimode mobile device transitions from a mobile wireless environment to a private network environment;

determining the local time from the second protocol data substantially when the multimode mobile device transitions from the mobile wireless environment to the private network environment; and

transmitting the network identification and the local time to the multimode mobile device.

8. The method of claim 7, wherein the receiving the first protocol data further comprises, receiving a network identifier comprising a service set identification (SSID) that uniquely identifies at least one of a basic service set (BSS) or an extended service set (ESS).

9. The method of claim 8, wherein the extracting further comprises, comparing the SSID to a lookup table to determine the network identification and a human readable network name.

10. The method of claim 9, wherein the transmitting further comprises, transmitting the human readable network name.

11. The method of claim 7, wherein the receiving further comprises, receiving the second protocol data from at least one of a Dynamic Host Configuration Protocol (DHCP) service, a Session Initiation Protocol (SIP) service, an Extensible Authentication Protocol (EAP) service, or a Network Time Protocol (NTP) service.

12. The method of claim 7, wherein the receiving further comprises, receiving the second protocol data from at least one of a wireless access point, a protocol server, a wireless router, or the multimode device.

13. The method of claim 7, wherein the extracting further comprises, extracting a human readable network name.

14. The method of claim 13, wherein the determining further comprises, determining a current time zone.

15. The method of claim 14, wherein the transmitting further comprises, transmitting the human readable network name and the current time zone.

16. The method of claim 15, further comprising:

displaying, on an interface associated with the multimode mobile device, the human readable network name, the current time zone and the local time.

17. The method of claim 7, wherein the receiving further comprises, receiving the second protocol data from a Dynamic Host Configuration Protocol (DHCP) service, the DHCP service including time zone information in the form of an offset in seconds from Coordinated Universal Time (UTC).

18. The method of claim 7, wherein the receiving further comprises, receiving the second protocol data from a Session Initiation Protocol (SIP) service, the SIP service including a facility to carry time zone information during the initiation of a session.

19. The method of claim 7, wherein the receiving further comprises, receiving the second protocol data from an Extensible Authentication Protocol (EAP) service which provides location or time zone information as part of the authentication process.

20. A method for determining a human readable network name, comprising

obtaining a network identifier from a wireless access point;

extracting from the network identifier a network name;

ascertaining the human readable network name based on a pre-provisioned database and the network name; and

displaying the human readable network name.
