System and method for supporting GAN service request capability in a wireless user equipment (UE) device
View Patent ↗In one embodiment, a scheme is disclosed for supporting wireless access network service request capability in a user equipment (UE) device that is operable in wide area cellular network (WACN) bands as well as in wireless access network bands (e.g., GAN bands and/or UMA bands). The UE device includes capability for gaining Internet Protocol (IP) connectivity with a wireless access network node (e.g., a GAN controller (GANC) or UMA network controller (UNC)). Thereafter, the UE device is operable to initiate a registration request message towards the wireless access network node, wherein the registration request message includes at least one information element pertaining to wireless access network services required by the UE device.
1. A network messaging method operating on a user equipment (UE) device, the method comprising:
connecting with an Internet Protocol (IP) access point; transmitting a registration request message by said UE device towards a default generic access network controller (GANC), said registration request including a request for one or more PLMN services provided through a GANC; and
receiving a registration redirection message from the default GANC, the registration redirection message redirecting the UE device to another GANC, based on the information received from the UE device.
2. The network messaging method as recited in claim 1 , wherein the one or more PLMN services comprise at least one of voice-only services, data-only services, voice-and-data services, multimedia services, value-added services and Unlicensed Mobile Access (UMA) services.
3. The network messaging method as recited in claim 1 , wherein said default GANC is coupled to at least one PLMN comprising one 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, and a Universal Mobile Telecommunications System (UMTS) network.
4. The network messaging method as recited in claim 1 , wherein the default GANC is a GANC that is identified with a Uniform Resource Locator (URL) stored in the UE device.
5. The network messaging method as recited in claim 1 , wherein the default GANG is a GANC that is identified with an IP address stored in the UE device.
6. The network messaging method as recited in claim 1 , wherein the default GANC is a GANC that is identified with a Fully Qualified Domain Name (FQDN) stored in the UE device.
7. The network messaging method as recited in claim 1 , wherein the registration request message further includes network information gathered by the UE device.
8. The network messaging method as recited in claim 7 , wherein the network information comprises at least one of Cell Global Identification (CGI) information of a registered PLMN, CGI information relating to available PLMNs, cause values of any prior registration failures, Broadcast Control Channel (BCCH) information of at least one available PLMN, and Packet Control Channel (PCCH) information of at least one available PLMN.
9. The network messaging method as recited in claim 1 , wherein said default GANC is coupled to a home PLMN associated with the UE device.
10. The network messaging method as recited in claim 1 , wherein said default GANC is coupled to a visited PLMN with respect to the UE device.
11. The network messaging method as recited in claim 1 , wherein the connecting of the UE device with the IP access point is performed using at least one of IEEE 802.11b standard, IEEE 802.11a standard, IEEE 802.11g standard, HiperLan and HiperLan II standards, Wi-Max standard, OpenAir standard, and the Bluetooth standard.
12. A user equipment (UE) device, comprising:
a processor configured to control at least one of a plurality of sub-systems to connect with an Internet Protocol (IP) access point;
the processor further configured to control at least one of the plurality of sub-systems to transmit a registration request message including a request for one or more PLMN services provided through a GANC; and
the processor still further configured to control at least one of the plurality of sub-systems to a process a registration redirection message received from the default GANC, the registration redirection message redirecting the UE device to another GANC, based on the information received from the UE device.
13. The UE device as recited in claim 12 , wherein the one or more PLMN services comprise at least one of voice-only services, data-only services, voice-and-data services, multimedia services, value-added services and Unlicensed Mobile Access (UMA) services.
14. The UE device as recited in claim 12 , further comprising a component configured to store an address of the default GANG.
15. The UE device as recited in claim 14 , wherein the address of the default GANC is a Uniform Resource Locator (URL).
16. The UE device as recited in claim 14 , wherein the address of the default GANC is an IP address.
17. The UE device as recited in claim 14 , wherein the address of the default GANC is a Fully Qualified Domain Name (FQDN).
18. The UE device as recited in claim 12 , wherein the processor is still further configured to control at least one of the plurality of sub-systems to gather network information and include the network information in the registration request message.
19. The UE device as recited in claim 18 , wherein the network information comprises at least one of Cell Global Identification (CGI) information of a registered PLMN, CGI information relating to available PLMNs, cause values of any prior registration failures, Broadcast Control Channel (BCCH) information of at least one available PLMN, and Packet Control Channel (PCCH) information of at least one available PLMN.
20. The UE device as recited in claim 12 , wherein the processor is configured to control at least one of the plurality of sub-systems to connect the UE device with the IP access point using at least one of IEEE 802.11b standard, IEEE 802.11a standard, IEEE 802.11g standard, HiperLan and HiperLan II standards, Wi-Max standard, OpenAir standard, and the Bluetooth standard.
21. A generic area network controller (GANC) comprising:
a component configured to process a registration request message received from a user equipment (UE) device, wherein the registration request message includes a request for one or more PLMN services; and
a component configured to transmit a registration redirection message to the UE device, the registration redirection message redirecting the UE device to a another GANC, based on the information received from the UE device.
22. The GANC as recited in claim 21 , wherein the one or more PLMN services requested by the UE device comprise at least one of voice-only services, data-only services, voice-and-data services, multimedia services, value-added services and Unlicensed Mobile Access (UMA) services.
23. The GANC as recited in claim 21 , wherein the register request message received from the UE device further includes network information gathered by the UE device.
24. The GANC as recited in claim 23 , wherein the network information comprises at least one of Cell Global Identification (CGI) information of a registered PLMN, CGI information relating to available PLMNs, cause values of any prior registration failures, Broadcast Control Channel (BCCH) information of at least one available PLMN, and Packet Control Channel (PCCH) information of at least one available PLMN.
