Abstract
Method and systems for managing a communication link. One or more indicators of an expected service interruption associated with a communication link is determined. The communication link may be a link between a relay and a communication target and/or a link between the relay and a user equipment (UE). In response, the UE initiates one or more actions to reduce or avoid the expected service interruption.
Claims20
A method for managing continuity of a communication service, the method comprising:
- receiving by a first User Equipment (UE), from a first relay, a first message indicative of a change to a condition related to maintenance of at least one of:
- a first radio communication link between the first relay and a communication target, and
- a second radio communication link between the first relay and the first UE;
- receiving, by the first UE, a broadcast information block from a second relay;
- wherein the first message is configured to cause the first UE to initiate a procedure for selecting a target relay to provide the communication service by performing a direct discovery to find the target relay using information provided in the broadcast information block.
A system for managing continuity of a communication service, the system comprising:
- a communication interface for wireless communication;
- and
- a processor configured to execute instructions to cause the system to:
- receive by a first User Equipment (UE) from a first relay a message indicative of a change to a condition related to maintenance of at least one of:
- a first radio communication link between the first relay and a communication target, and
- a second radio communication link between the first relay and the first UE;
- receive, by the first UE, a broadcast information block from a second relay;
- wherein the first message is configured to cause the first UE to initiate a procedure for selecting a target relay to provide the communication service by performing a direct discovery to find the target relay using information provided in the broadcast information block.
A non-transitory computer-readable medium comprising computer-executable instructions that, when executed by a processor of a wireless communication system, causes the system to:
- receive, by a first User Equipment (UE), from a first relay, a first message indicative of a change to a condition related to maintenance of at least one of:
- a first radio communication link between the first relay and a communication target, and
- a second radio communication link between the first relay and the first UE;
- and
- receive, by the first UE, a broadcast information block from a second relay;
- wherein the first message is configured to cause the first UE to initiate a procedure for selecting a target relay to provide the communication service by performing a direct discovery to find the target relay using information provided in the broadcast information block.
