Abstract: A method of facilitating P-CSCF restoration when a P-CSCF failure has occurred is disclosed. The method comprises a Proxy Call Session Control Function, ‘P-CSCF’ receiving a Session Initiation Protocol, ‘SEP’, message when said P-CSCF has been selected as an alternative P-CSCF to a failed P-CSCF and providing, to an associated Policy and Charging Rules Function, ‘PCRF’, a message comprising an indication that P-CSCF restoration is required.

Abstract: There is provided a solution as to how the authentication and thus the authorization of the webRTC IMS Client can be achieved in the IMS of the mobile network operator. The WIC (20) is using an ID to register with IMS, which may be an IMPU, an IMPI, gGRUU etc. The WIC (20) may be preconfigured by the WWSF (30) with the eP-CSCF (40) address and authentication information, but if not, then this information should be retrieved via the WWSF (30) or from the IMS directly or via other device management procedures e.g. OMA DM. It is further assumed that the subscriber has already a valid webRTC account/membership and this can be validated, authenticated and authorized by the WWSF (30).

Abstract: This invention provides a network node for IP Multimedia Subsystem (IMS) Centralized Services (ICS), comprising: a memory storing instructions; and at least one processor configured to process the instructions to: receive an Update Location Request with an IMSI (International Mobility Subscriber Identity) and an MSRN (Mobile Station Routing Number) from a MSC (Mobile Switching Centre) Server, retrieve a subscription profile and service settings from a HSS (Home Subscriber Server), map the subscription profile with service settings into a CS (Circuit-Switched) profile with CS settings, and send an Insert Subscriber Data message including the mapped CS profile and CS settings, to the MSC Server.

Abstract: The invention provides for a method of selecting a Dedicated Core Network (DCN) based on assisting indication by mobile terminals, and including the step of configuring the RAN Nodes of the mobile network with the DCN Types of the serving EPC Nodes so that the RAN Nodes can map the DCN selection assisting information from the connecting mobile terminals with the right dedicated EPC Node. This allows for the RAN Node to connect the mobile terminals with EPC Node of the mobile terminal's dedication at initial attach and then keep the mobile terminals on the same DCN. Thus, a re-routing of mobile terminals NAS message from one EPC Node to another EPC node is avoided. The invention also allows for a flexible and dynamic change of the EPC Nodes dedication based on operator's configuration and policy. Additionally, the invention allows for DCN access restriction control by broadcasting of the supported DCN Types by the RAN Node.

Abstract: A communication entity includes a Proxy Call Session Control Function (P-CSCF). The P-CSCF includes a transceiver and a controller. The transceiver is operable to receive a register request from a user equipment (UE) in a visited public land mobile network (VPLMN). The controller is operable to: retrieve a network identifier (PLMN ID) for the VPLMN by requesting the PLMN ID where the UE is currently located from a Policy Control Rule Function (PCRF); access a database to obtain a list of local emergency numbers for the VPLMN; and include the retrieved PLMN ID in the register request before forwarding the register request to a Call Session Control Function (CSCF).

Abstract: A communication system is disclosed in which a home subscriber server, ‘HSS’, of a communication network, receives, from a service capability exposure function, ‘SCEF’, at least one communication pattern parameter set together with an associated validity time, stores the at least one communication pattern parameter set, and when the validity time for a communication pattern parameter set stored in the HSS expires, autonomously deletes the associated communication pattern parameter set.

Abstract: A communication system is disclosed in which a base station receives, from a communication device, NAS signalling for establishing a connection via the base station. The base station forwards the NAS signalling to a default MME for setting up the connection to the default MME. The default MME sends, responsive to the base station forwarding the NAS said signalling, a message identifying an MME group to which the NAS signalling should be rerouted. The base station selects an MME based an the message identifying the MME group, and forwards the NAS signalling to the selected MME, and includes information indicating that the NAS signalling shall not be rerouted.

Abstract: In order for making MTC more efficient and/or secure, a base station forming a communication system connects a UE to a core network. A node serves as an entering point to the core network for a service provider, and transmits traffic between the service provider and the UE. The node establishes, as a connection to the base station, a first connection for directly transceiving messages between the node and the base station. Alternatively, the node establishes a second connection for transparently transceiving the messages through a different node that is placed within the core network and has established a different secure connection to the base station.

Abstract: A method for signalling congestion avoidance based on Non-Access Stratum (NAS) level congestion control in a mobile network includes activating or starting a group specific NAS level congestion control mechanism that applies to a group of terminals; receiving at a serving node of a terminal of the group of terminals an NAS Session Management (SM) request message from the terminal related to a particular access point name (APN); and transmitting from the serving node of the terminal to the terminal one or more NAS reject messages that indicate suppression or prevention of NAS SM signalling of the terminal that is related either to all APNs to which the terminal has established or activated IP bearers or to all APNs to which the terminal has a subscription.

Abstract: A system is described in which a default MME (9A) receives a NAS message (S501, S505) from a mobile device (3D); sends a rerouting request (S509) to a base station (5) serving the mobile device (3D) and includes information identifying a group of dedicated MMEs (9D) to which the NAS message should be rerouted. If none of the dedicated MMEs (9D) is available, then the default MME (9A) receives a message from the base station (5), the message rerouting the NAS message to the default MME (9A), instead of a dedicated MME (9D). The default MME (9A) either proceeds (S515a) to serving the mobile device (3D) or the default MME (9A) rejects (S515b) the NAS message.

Abstract: In order for making MTC more efficient and/or secure, a base station (20) forming a communication system connects a UE (10) to a core network. A node (50) serves as an entering point to the core network for a service provider, and transmits traffic between the service provider and the UE (10). The node (50) establishes, as a connection to the base station (20), a first connection for directly transceiving messages between the node (50) and the base station (20). Alternatively, the node (50) establishes a second connection for transparently transceiving the messages through a different node (30) that is placed within the core network and has established a different secure connection to the base station (20).

Abstract: A method for providing device connectivity to a radio access network, wherein at least two devices are connectable or connected to the radio access network and wherein the at least two devices are members of a group of devices within a wireless local network, the members of the group of devices having the capability to establish a direct connection with other members of the group of devices, includes providing connection information used for a connection between a first device of the at least two devices and the radio access network to a second device of the at least two devices. The connection information enables the second device to connect to the radio access network.

Abstract: Upon requesting an MME (40) to handover a UE (10) to a Target MeNB (20_2), a Source MeNB (20_1) sends, to the Target MeNB (20_2) through the MME (40), information on one or more SeNBs that are candidates available for dual connectivity under control of the Target MeNB (20_2). The Target MeNB (20_2) configures a Target SeNB (30_2) that is selected based on the information to provide the dual connectivity. Alternatively, the Source MeNB (20_1) sends, to the Target MeNB (20_2), information on a Source SeNB (30_1) that has been used by the Source MeNB (20_1) for the dual connectivity. In this case, the Target MeNB (20_2) skips RRC configuration for the Source SeNB (30_1) upon the control.
