Relating to interworking between cellular and WLAN networks
A method of operating a mobile terminal in a mobile communications network comprising a core network and a base station, wherein the mobile terminal is capable of transmitting data to and receiving data from the core network via the mobile base station or via a WLAN includes in the event that the WLAN becomes unavailable, reporting the WLAN unavailability to the mobile communications network, and detecting the WLAN becoming available again, and notifying the mobile communications network. A mobile terminal includes a transceiver configured to transmit data to and receive data from the core network via the mobile base station or via a WLAN, a controller configured to in the event that the WLAN becomes unavailable, report the WLAN unavailability to the mobile communications network via the transceiver, and detect the WLAN becoming available again, and notify the mobile communications network.
1. A method for monitoring network status by a user equipment (UE), the method comprising:
transmitting, to a cellular network, a connection status report indicating that a wireless local area network (WLAN) is unavailable, in case a connection to the WLAN included in a mobility set fails;
removing, by the UE, measurement reporting entries associated with the WLAN within a list;
transmitting, to the cellular network, a measurement report including measurement information associated with the WLAN, in case the WLAN becomes available after removing the measurement reporting entries associated with the WLAN; and
transmitting, to the cellular network, a connection status report indicating that the WLAN is available, following reporting of WLAN unavailability, if the WLAN becomes available after removing the measurement reporting entries associated with the WLAN,
wherein the connection status report indicating that the WLAN is available is transmitted only if the UE is configured with a measurement object for WLAN.
2. A method for receiving a network status by a cellular network, the method comprising:
receiving, from a user equipment (UE), a connection status report indicating that a wireless local area network (WLAN) is unavailable, in case a connection to the WLAN included in a mobility set fails;
transmitting, to the UE, a message associated with releasing offloading configuration for the WLAN;
receiving, from the UE, a measurement report including measurement information associated with the WLAN, in case the WLAN becomes available after measurement reporting entries associated with the WLAN is removed by the UE within a list; and
receiving, from the UE, a connection status report indicating that the WLAN is available, following reporting of WLAN unavailability, if the WLAN becomes available after the measurement reporting entries associated with the WLAN is removed,
wherein the connection status report indicating that the WLAN is available is received only if the UE is configured with a measurement object for WLAN.
3. A user equipment (UE) for monitoring network status, the UE comprising:
a transceiver; and
a controller coupled with the transceiver and configured to control to:
transmit, to a cellular network, a connection status report indicating that a wireless local area network (WLAN) is unavailable, in case a connection to the WLAN included in a mobility set fails,
remove measurement reporting entries associated with the WLAN within a list,
transmit, to the cellular network, a measurement report including measurement information associated with the WLAN, in case the WLAN becomes available after removing the measurement reporting entries associated with the WLAN; and
transmit, to the cellular network, a connection status report indicating that the WLAN is available, following reporting of WLAN unavailability, if the WLAN becomes available after removing the measurement reporting entries associated with the WLAN,
wherein the connection status report indicating that the WLAN is available is transmitted only if the UE is configured with a measurement object for WLAN.
4. A cellular network for receiving a network status, the cellular network comprising:
a transceiver; and
a controller coupled with the transceiver and configured to control to:
receive, from a user equipment (UE), a connection status report indicating that a wireless local area network (WLAN) is unavailable, in case a connection to the WLAN included in a mobility set fails,
transmit, to the UE, a message associated with releasing offloading configuration for the WLAN,
receive, from the UE, a measurement report including measurement information associated with the WLAN, in case the WLAN becomes available after measurement reporting entries associated with the WLAN is removed by the UE within a list, and
receive, from the UE, a connection status report indicating that the WLAN is available, following reporting of WLAN unavailability, if the WLAN becomes available after the measurement reporting entries associated with the WLAN is removed,
wherein the connection status report indicating that the WLAN is available is received only if the UE is configured with a measurement object for WLAN.
