View Patent ↗A user equipment (UE) is provided that includes one or more processors configured to perform one of an attach procedure, Routing Area Update (RAU), or Tracking Area Update (TAU), and then cause the UE to provide an indication to a network, wherein the indication indicates whether the UE has determined a voice solution in an Evolved Universal Mobile Telecommunications System Terrestrial Radio Access Network (E-UTRAN).
1. A user equipment (UE), comprising:
one or more processors configured to perform one of an attach procedure, Routing Area Update (RAU), or Tracking Area Update (TAU), and then cause the UE to provide an indication to a network, wherein the indication indicates whether the UE has determined a voice solution in an Evolved Universal Mobile Telecommunications System Terrestrial Radio Access Network (E-UTRAN).
2. The UE of claim 1 wherein the indication is further configured to allow a SGSN to know whether the UE can be handed over to the E-UTRAN.
3. The UE of claim 1 wherein the indication is implemented by inserting a value into a voice centric or data centric setting information element.
4. The UE of claim 1 wherein the indication is implemented using a specific information element that indicates whether the UE can be handed over the E-UTRAN, and wherein the information element is used in at least one of GPRS signaling, EPC attach signaling, RAU signaling, or TAU signaling.
5. The UE of claim 1 wherein the processor is configured to provide the indication responsive to all of 1) the UE being combined attached over an E-UTRAN, 2) the UE has provided voice and usage settings to a network, 3) the UE is IDLE camping in a GERAN or UTRAN, and 4) the UE becomes packet switched connected over the GERAN or UTRAN.
6. The UE of claim 1 wherein the processor is configured to provide the indication responsive to the UE having not determined if the UE has a voice solution in the E-UTRAN.
7. A method implemented in a user equipment (UE), the method comprising:
performing, by a processor, one of an attach procedure, Routing Area Update (RAU), or Tracking Area Update (TAU); and
thereafter causing the UE to provide an indication to a network, wherein the indication indicates whether the UE has determined a voice solution in an Evolved Universal Mobile Telecommunications System Terrestrial Radio Access Network (E-UTRAN).
8. The method of claim 7 , wherein the indication is further configured to allow a SGSN to know whether the UE can be handed over to the E-UTRAN.
9. The method of claim 7 , wherein the indication is implemented by inserting a value into a voice centric or data centric setting information element.
10. The method of claim 7 , wherein the indication is implemented using a specific information element that indicates whether the UE can be handed over the E-UTRAN, and wherein the information element is used in at least one of GPRS signaling, EPC attach signaling, RAU signaling, or TAU signaling.
11. The method of claim 7 , wherein the processor is configured to provide the indication responsive to all of 1) the UE being combined attached over an E-UTRAN, 2) the UE has provided voice and usage settings to a network, 3) the UE is IDLE camping in a GERAN or UTRAN, and 4) the UE becomes packet switched connected over the GERAN or UTRAN.
12. The method of claim 7 , wherein the processor is configured to provide the indication responsive to the UE having not determined if the UE has a voice solution in the E-UTRAN.
13. A non-transitory computer readable medium storing a program which, when executed, performs the processor-implemented steps of:
a user equipment (UE) performing one of an attach procedure, Routing Area Update (RAU), or Tracking Area Update (TAU); and
thereafter causing the UE to provide an indication to a network, wherein the indication indicates whether the UE has determined a voice solution in an Evolved Universal Mobile Telecommunications System Terrestrial Radio Access Network (E-UTRAN).
14. The non-transitory computer readable medium of claim 13 , wherein the indication is further configured to allow a SGSN to know whether the UE can be handed over to the E-UTRAN.
15. The non-transitory computer readable medium of claim 13 , wherein the indication is implemented by inserting a value into a voice centric or data centric setting information element.
16. The non-transitory computer readable medium of claim 13 , wherein the indication is implemented using a specific information element that indicates whether the UE can be handed over the E-UTRAN, and wherein the information element is used in at least one of GPRS signaling, EPC attach signaling, RAU signaling, or TAU signaling.
17. The non-transitory computer readable medium of claim 13 , wherein the UE is configured to provide the indication responsive to all of 1) the UE being combined attached over an E-UTRAN, 2) the UE has provided voice and usage settings to a network, 3) the UE is IDLE camping in a GERAN or UTRAN, and 4) the UE becomes packet switched connected over the GERAN or UTRAN.
18. The non-transitory computer readable medium of claim 13 , wherein the UE is configured to provide the indication responsive to the UE having not determined if the UE has a voice solution in the E-UTRAN.
