Abstract
The present invention relates to a method of transmitting a signal by an MME (Mobility Management Entity) in a wireless network, the method comprising: receiving a tracking area update message from an UE (User Equipment); transmitting, on reception the tracking area update message, an Update Location message comprising an IMS voice over PS (Packet Switched) session supported indication to an HSS (Home Subscriber Server), wherein the IMS voice over PS session supported indication indicates whether or not an IMS Voice over PS Session is supported homogeneously in all tracking areas in the serving MME.
Claims15
A method of transmitting a signal by a mobility management entity (MME) in a wireless network, the method comprising:
- receiving a tracking area update message originated from a user equipment (UE);
- and
- transmitting, to a home subscriber server (HSS), based on reception of the tracking area update message to update location information of the UE, an update location message including information, which is used to select a domain between one of a packet switch or a circuit switch in a terminating access domain selection (TADS), to indicate whether an internet protocol (IP) multimedia subsystem (IMS) voice over packet switched (PS) session is supported homogeneously in tracking areas for the UE in the MME.
A mobility management entity (MME) in a wireless network, the MME comprising:
- a transceiver configured to transmit and receive a signal;
- and
- a controller configured to:
- receive a tracking area update message originated from a user equipment (UE), and
- transmit, to a home subscriber server (HSS), based on reception of the tracking area update message to update location information of the UE, an update location message comprising information, which is used to select a domain between one of a packet switch or a circuit switch in a terminating access domain selection (TADS), to indicate whether an internet protocol (IP) multimedia subsystem (IMS) voice over packet switched (PS) session is supported homogeneously in tracking areas for the UE in the MME.
A system in a wireless network, the system comprising:
- a user equipment (UE) configured to transmit a tracking area update message;
- and
- a mobility management entity (MME) configured to:
- receive the tracking area update message originated from the UE, and
- transmit, based on reception of the tracking area update message to update location information of the UE, to a home subscriber server (HSS), an update location message comprising information, which is used to select a domain between one of a packet switch or a circuit switch in a terminating access domain selection (TADS), to indicate whether an internet protocol (IP) multimedia subsystem (IMS) voice over packet switched (PS) session is supported homogeneously in tracking areas for the UE in the MME,
- wherein the HSS configured to receive the update location message from the MME.
