Abstract
A wireless terminal can communicate with two radio access networks (RAN) (304, 306) of different types. The wireless terminal can register simultaneously with a RAN of the first type and a RAN of the second type and can wirelessly connect to a RAN of either the first type or the second type in a connected state. The wireless terminal when registered with both a first RAN and a second RAN and when wirelessly connected to the first RAN in the connected state, receives a mobility signal via the first RAN indicating a RAN of the second type and, in response to receiving the mobility signal and in response to being so registered with the first RAN and second RAN, transmits an access trigger signal (417). The access trigger signal indicates that the wireless terminal is to be connected to the second RAN in the connected state.

Claim
1. A method comprising:
receiving a mobility command from a first Radio Access Network (RAN), performing a cell change order to a second RAN; and deactivating, when a user equipment (UE) moves from the first RAN connected mode to the second RAN via the cell change order, an Idle mode Signaling Reduction (ISR) by setting a temporary identifier (TIN) to globally unique temporary identifier (GUTI) before initiating a routing area (RA) update procedure.
2. The method according to claim 1,
wherein the UE is configured to be registered with both a first apparatus via the first RAN and a second apparatus via the second RAN.
3. The method according to claim 1,
wherein the first RAN is Evolved Universal Terrestrial Radio Access Network (E-UTRAN) and the second RAN is GSM EDGE Radio Access Network (GERAN).
4. The method according to claim 1,
wherein the RA update procedure is initiated by an access trigger signal, the access trigger signal being a RAU (Routing Area Update) message.
5. The method according to claim 2,
wherein the first apparatus is Mobility Management Entity (MME), and wherein the second apparatus is Serving GPRS Support Node (SGSN).
6. A user equipment (UE) comprising:
a receiver configured to receive a mobility command from a first Radio Access Network (RAN), a processor configured to perform a cell change order to a second RAN, wherein the processor configured to deactivate, when the UE moves from the first RAN connected mode to the second RAN via the cell change order, an Idle mode Signaling Reduction (ISR) by setting a temporary identifier (TIN) to globally unique temporary identifier (GUTI) before initiating a routing area (RA) update procedure.
7. The user equipment according to claim 6,
wherein the UE is configured to be registered with both a first apparatus via the first RAN and a second apparatus via the second RAN.
8. The user equipment according to claim 6,
wherein the first RAN is Evolved Universal Terrestrial Radio Access Network (E-UTRAN) and the second RAN is GSM EDGE Radio Access Network (GERAN).
9. The user equipment according to claim 6,
wherein the RA update procedure is initiated by an access trigger signal, the access trigger signal being a RAU (Routing Area Update) message.
10. The user equipment according to claim 7,
wherein the first apparatus is Mobility Management Entity (MME), and wherein the second apparatus is Serving GPRS Support Node (SGSN).
