US 11,638,321 B2 · User equipment signaling of temporary change in service availability

Abstract

Embodiments include systems and methods for UE signaling a network regarding customized ringing signal (CRS) capability and use of such information by the network. Various embodiments may receiving from the network an INVITE message notifying the UE of an incoming call, determining whether the INVITE message indicates that the network provides CRS service if the UE supports a CRS function, and including an indication in a response to the INVITE that the UE supports the CRS function in response to determining that the INVITE message includes an alert information header field indicating that the network provides CRS service. Various embodiments include a network computing device receiving such information and performing negotiations for CRS service with the UE only if the UE indicates CRS functional capability.

Dependent claims

A method performed by a wireless user equipment (UE), the method comprising:

establishing with a base station a communication link supporting communication services between the UE and the base station;
determining an anticipated temporary change in service availability of the UE based on an anticipated movement of the UE;
and
transmitting a message to the base station indicating the anticipated temporary change in service availability of the UE before the anticipated movement of the UE.

1 more element

A wireless user equipment (UE), comprising:

a wireless transceiver;
and
a processor coupled to the wireless transceiver and configured to:
establish with a base station a communication link supporting communication services between the UE and the base station;
determine an anticipated temporary change in service availability of the UE based on an anticipated movement of the UE;
and
transmit a message to a base station indicating the anticipated temporary change in service availability of the UE before the anticipated movement of the UE.

4 more elements

A method performed by a base station in a wireless communication network for maintaining wireless communications with a wireless user equipment (UE), the method comprising:

establishing with the UE a communication link supporting communication services between the UE and the base station;
receiving a message from the UE indicating an anticipated temporary change in service availability of the UE due to an anticipated movement of the UE;
and
taking an action in response to the message from the UE to accommodate the anticipated temporary change in service availability due to the anticipated movement of the UE.

1 more element

A base station, comprising:

a processor configured with processor-executable instructions to perform operations comprising:
establishing with a wireless user equipment (UE) a communication link supporting communication services between the UE and the base station;
receiving a message from a wireless user equipment (UE) indicating an anticipated temporary change in service availability of the UE due to an anticipated movement of the UE;
and
taking an action in response to the message from the UE to accommodate the anticipated temporary change in service availability due to the anticipated movement of the UE.
