Abstract
Examples pertaining to user equipment (UE) reachability after notification in mobile communications are described. An apparatus (e.g., UE) receives an indication to initiate a notification procedure from a network over a non-3rd Generation Partnership Project (non-3GPP) access while a 3GPP access with the network is unavailable. In response, the apparatus transmits a notification response message to the network. After the 3GPP access with the network becomes available, the apparatus indicates to the network that the apparatus is reachable over the 3GPP access.
Claims19
A method, comprising:
- receiving, by a processor of an apparatus, an indication to initiate a notification procedure from a network over a non-3rd Generation Partnership Project (non-3GPP) access while a 3GPP access with the network is unavailable;
- transmitting, by the processor, a notification response message to the network responsive to the receiving;
- and
- after the 3GPP access with the network becomes available, indicating, by the processor, to the network that the apparatus is reachable over the 3GPP access,
- wherein the indicating to the network that the apparatus is reachable over the 3GPP access comprises indicating to the network that the apparatus is reachable over the 3GPP access while there is no need of non-access stratum (NAS) signaling over the 3GPP access.
A method, comprising:
- receiving, by a processor of an apparatus, an indication to initiate a notification procedure from a network over a non-3rd Generation Partnership Project (non-3GPP) access a while a 3GPP access with the network is unavailable;
- transmitting, by the processor, a notification response message to the network responsive to the receiving;
- and
- after the 3GPP access with the network becomes available, transmitting, by the processor, an indication message to the network over the non-3GPP access that the apparatus is reachable over the 3GPP access,
- wherein the transmitting of the indication message to the network over the non-3GPP access that the apparatus is reachable over the 3GPP access comprises transmitting the indication message to the network that the apparatus is reachable over the 3GPP access while there is no need of non-access stratum (NAS) signaling over the 3GPP access.
A method, comprising:
- receiving, by a processor of an apparatus, an indication to initiate a procedure from a network over a first type of access, when there is downlink (DL) data for a protocol data unit (PDU) session associated with a second type of access to be transferred over the second type of access, while the second type of access with the network is unavailable;
- transmitting, by the processor, a response message to the network responsive to the receiving;
- and
- after the second type of access with the network becomes available, indicating, by the processor, to the network that the apparatus is reachable over the second type of access regardless of a need for signaling over the second type of access,
- wherein the indicating to the network that the apparatus is reachable over the second type of access comprises indicating to the network that the apparatus is reachable over a 3rd Generation Partnership Project (3GPP) access while there is no need of non-access stratum (NAS) signaling over the 3GPP access.
