Methods and arrangements in a cellular communication network

摘要

The present invention relates to methods and arrangements for resolving radio resource conflicts occurring in radio networks supporting both local ad-hoc communication and cellular communication. The conflicts are resolved by informing the cellular network about radio resource management restrictions due to the local ad-hoc communication needs and resources that are reserved for local ad-hoc communications.

主权项

1. A method in a User Equipment, UE, comprising at least one radio access communication interface supporting cellular and local ad-hoc communication, the method comprising:
establishing a local communication to an ad-hoc network; and sending via a cellular connection, to a node of a cellular network, information about radio resource utilization resulting in resource restrictions for cellular communication due to the local ad-hoc communication, wherein the UE comprises at least a first communication interface for a first cellular network configured according to a first radio access technology, RAT, and a second communication interface for a second cellular network configured according to a second RAT, the method further comprising operating only one of the first and second communication interfaces at any time, and wherein the information about radio resource utilization resulting in resource restrictions for cellular communication due to the local ad-hoc communication comprises recommendations that the UE should not be handed over to certain radio access technologies.
