Abstract: There is provided a network apparatus, caused to: maintain a registration of at least one Network Repository Function (NRF) with respective associated information for selecting the at least one NRF; and, in response to a request for NRF information from a requesting network entity, provide the associated information to the requesting network entity.

Abstract: Systems, methods, apparatuses, and computer program products for packet data network gateway (PGW) selection for network slicing are provided.

Abstract: A mechanism for a user equipment is described. The mechanism comprises allocating a secure memory area, wherein said secure memory area being inaccessible by a user of the user equipment; generating an charging identifier relating to proximity communication involving the user equipment; collecting proximity service charging data during the proximity communication; storing the charging identifier and the proximity service charging data in the secure memory area.

Abstract: According to several embodiments of the present invention, a single session according to an authentication, authorization and accounting protocol, with a network element carrying out a policy and charging rule function is created, wherein the specific session may be used to manage and/or report policy and/or charging control rules.

Abstract: The present invention refers to providing of a load balancing, by use of a gateway network element comprising a group of load balanced access points. In particular, the load balancing is performed by selecting of an access point from said group of load balanced access points by use of an access point name, which is derived from a packet data protocol context activation request, said packet data protocol context activation request being transmitted by a mobile subscriber or node, respectively, and received by the gateway network element.

Abstract: The generation of charging data and charging traffic is reduced during idle periods of an always-on connection. During the detection of idle periods on the always-on connection special data like ICMP messages, keep alive messages and polling messages is ignored and not counted as active traffic. When an idle period is detected the charging session related to the always-on connection is suspended for the duration of the idle period in order to reduce the generation of charging data related to the idle always-on connection without terminating the charging session. Further on the user is not billed for the detected periods where the always-on connection was idle.

Abstract: A method of locating NAS context relating to a network access server session in a communication network is provided, the method comprising receiving an Accounting Stop Request for a PDP context associated to a network access server session, comparing an Accounting Session ID implemented in the Accounting Stop Request with Accounting Session IDs associated with active network access server sessions, in case that no matching Accounting Session ID is found, determining whether a value of an identification parameter implemented in the received Accounting Stop Request matches a value of a corresponding identification parameter associated with an active network access server session, and locating a NAS context based on the result of matching identification parameters.

Abstract: A method of deciding to release communication resources used for a network access server session in a communication network is provided, wherein the method involves receiving an Accounting Stop Request for a PDP context associated to the network access server session, deciding whether a Session Stop Indicator is included in the Accounting Stop Request, in case no Session Stop Indicator is included deciding whether further PDP contexts are associated with the network access server session, in case no further PDP context is associated with the network access server session, starting an IDLE Timer to determine a point in time for releasing the communication resources.

Abstract: According to several embodiments of the present invention, a single session according to an authentication, authorization and accounting protocol, with a network element carrying out a policy and charging rule function is created, wherein the specific session may be used to manage and/or report policy and/or charging control rules.

Abstract: According to several embodiments of the present invention, an information element for a first server controlling a first session according to an authentication, authorization and accounting protocol related to a bearer is generated, wherein the information element indicates that there is at least one second session according to the authentication, authorization and accounting protocol with at least one second server related to the same bearer, and that delegation of the first and the at least one second sessions is allowed.

Abstract: A method of providing service authorization by sending a message from a redirect server to a user terminal including an authorization token. The method includes detecting and removing the authorization token by a network gateway node from the message before forwarding the message to the user terminal.
