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.

Group identities in a communication system

According to an example aspect, there is provided a method, comprising: receiving, by a service communication proxy from a network function consumer, a service request for a service by a network function producer, transmitting, in response to an error in obtaining an access token from a network repository function on the basis of the service request, a response to the service request to the network function consumer, wherein the access token is for authorizing access to a service at the network function producer and the response is indicative of an access token error.

Network function request error handling

An aspect of the disclosed invention provides a network apparatus for a network function, the network apparatus comprising: at least one processor; and at least one memory comprising code that, when executed by the at least one processor, causes the network apparatus to: in response to a request from a service consumer, determine a first network service function for providing services to the service consumer; determine an identity of a second network service function, wherein the second network service function is an alternative or backup network service function to provide the service to the service consumer; and provide the service consumer with the identity of the second network service function.

Apparatus, methods, and computer programs

There is provided an apparatus for a Proxy Call Session Control Function (P-CSCF), the apparatus being arranged to send a first registration request to a network repository function for registering the P-CSCF with the network repository function, the first registration request comprising at least one first identifier for the P-CSCF over an interface between the P-CSCF and a user equipment.

A method for reducing wireless communication procedure failure. The method can include initiating a procedure over an existing radio resource control connection on a universal mobile telecommunication system. The method can also include receiving a connection release signal prior to receiving a response from a core network regarding the initiated procedure. The method can further include immediately retrying the procedure.
