Abstract
A method performed by a first UE. The method includes: the first UE sending via a first signaling protocol to a network node a service capabilities request, the service capabilities request requesting service capability information for a second UE; the first UE receiving from the network node a response to the service capabilities request, the response rejecting the service capabilities request; and as a result of receiving the response rejecting the service capabilities request, the first UE sending to the second UE, via a second signaling protocol other than the first signaling protocol, a service capabilities exchange invitation requesting an exchange of service capabilities.
Claims18
A first user equipment (UE), the first UE comprising:
- a processor;
- and
- a memory, said memory comprising instructions which when executed by the processor causes the first UE to:
- send to a server a query for capability information associated with a user of a second UE;
- receive, from the server, a response to the query, said response indicating that the user of the second UE is not found;
- and
- as a result of receiving the response to the query indicating that the user of the second UE is not found, send to the second UE a service capabilities request message requesting the capability information.
A method performed by a first user equipment (UE), the method comprising:
- sending to a server a query for capability information associated with a user of a second UE;
- receiving, from the server, a response to the query, said response indicating that the user of the second UE is not found;
- and
- as a result of receiving the response indicating that the user of the second UE is not found, sending to the second UE a service capabilities request message requesting the capability information.
A computer program product for providing for communication between a first user equipment (UE) and a second UE, the computer program product comprising a non-transitory computer readable medium storing instructions for:
- sending to a server a query for capability information associated with a user of the second UE;
- receiving, from the server, a response to the query, said response indicating that the user of the second UE is not found;
- and
- as a result of receiving the response indicating that the user of the second UE is not found, sending to the second UE a service capabilities request message requesting the capability information.
