Abstract: Embodiments of the present disclosure relate to method, device and computer readable media for communications. A first device receives, from a second device, a request for establishment of a connection between the first device and the second device. If a first set of security parameters associated with the connection is identical to a second set of security parameters associated with a previous connection which was completed between the first device and the second device, the first device performs the establishment of the connection.

Abstract: Apparatuses and methods for providing services in a communication system are disclosed. A request for a service provided by a service function entity in a network system is received, wherein the request indicates an identity of a user for which the service is requested. An identity of a group of service function entities capable of serving the user and determined based on the identity of the user is then provided, and an indication of the determined identity of the group is sent in the response for subsequent use by the sender of the request and/or at least one other entity involved in requests for services associated with the user.
