A method, apparatus and computer program product receive a traffic redundancy indication from a user equipment in a communication network or from a policy controller. The method, apparatus and computer program product determine whether traffic redundancy is needed for the radio access network and the user plane function based on the traffic redundancy indication. The method, apparatus and computer program product request the radio access network to not establish redundancy mechanisms in a circumstance where traffic redundancy is not needed for the radio access network. The method, apparatus and computer program product request the user plane function to not establish redundancy mechanisms in a circumstance where traffic redundancy is not needed for the user plane function.

Method and apparatus for redundancy improvement in a communication system

An embodiment of the invention is a User Equipment UE, configured to:

Enhancements to serving a user equipment in a visited country in a mobile communication system

In an embodiment, a method for support of emergency services over WLAN access to 3GPP Evolved Packet Core EPC for unauthenticated Users includes, in response to a request to provide a user identity for access authentication, a User Equipment UE providing a specific NAI-based user identity having a realm part indicating unauthenticated access for emergency services. Also includes an authenticator, such as TWAN entity for Trusted WLAN access or ePDG for Untrusted WLAN access, routing a message from said UE, based on said realm part, towards a specific 3GPP AAA Server serving a domain dedicated to unauthenticated access for emergency services, the specific 3GPP AAA Server granting access to the UE, and providing specific authorization data that allow network access for emergency services to the UE.

Support of emergency services over WLAN access to 3GPP packet core for unauthenticated users

A communication system includes a service responsible for sending signaling to a user equipment or an access network serving the user equipment. The service receives a request to send the signaling to the user equipment or the access network together with access type control information indicating whether the signaling is transmittable using any of a plurality of access types or a specific access type provided in the request. The service selectively forwards the signaling to the user equipment or the access network based on the access type control information.

Downlink signaling to user equipment in non-3GPP idle state

A UE activates a PS Data Off service to block downlink and uplink services except the exempted services determined by the HPLMN. To activate PS Data Off, the UE sends an indication to the MME or SGSN, or additionally to a S-CSCF or an IMS network. The UE may receive a confirmation of the PS Data Off activation and/or a list of exempt services. The MME may contact the HSS to notify about the activation of the PS Data Off and receive indication of support of the service or list of exempted services and send the indication and/or packet filtering per PDN to PDN GW(s). The PDN GW may contact a PCRF to get policy rules. The HSS may provide a list of exempt services to the S-CSCF.

Support of PS Data Off in a mobile system

Embodiments of the invention include an entity such as TWAN entity, respectively ePDG, capable of serving a User Equipment UE at Trusted, respectively Untrusted, WLAN access to a packet Core Network such as EPC, said entity configured to: &#x2014;perform DCN selection at said Trusted, respectively Untrusted, WLAN access of said UE to said packet Core Network such as EPC.

Support of dedicated core networks for WLAN access

Embodiments of the invention include an entity, such as ePDG or TWAN entity, capable of serving a User Equipment for WLAN access to a Packet Core such as EPC of a mobile network, said entity configured to:

Support of IMEI checking for WLAN access to a packet core of a mobile network

An embodiment of the present invention is a method for support of Circuit Switched (CS) fallback in an Evolved Packet System (EPS), said support including moving a User Equipment (UE) from an evolved Radio Access Network (RAN) to a legacy RAN for access to CS domain services, and moving back said UE from said legacy RAN to said evolved RAN at termination of said CS domain services, said support including moving back said UE to said evolved RAN in the Public Land Mobile Network (PLMN) that was serving said UE over said evolved RAN before moving said UE to said legacy RAN.

Support of CS fallback in an evolved packet system

The apparatus includes a processor configured to send, over a 3rd Generation Partnership project (3GPP) access, a notifying message regarding non-3GPP access to a user equipment, the user equipment being simultaneously registered to the communication network via the 3GPP access and via the non-3GPP access, the user equipment being in a connection management-idle state over the non-3GPP access. The method includes sending over a 3rd Generation Partnership project (3GPP) access a notifying message regarding non-3GPP access to a user equipment, the user equipment being simultaneously registered to a communication network via the 3GPP access and via the non-3GPP access, the user equipment being in a connection management-idle state over the non-3GPP access.

Method and apparatus for terminals registered via multiple access networks

A method is described for the support of nomadic or fixed users in a mobile network. The mobile network may include a Core Network CN accessed by a Radio Access Network RAN. The mobile network may provide connectivity, referred to as PDN connectivity, between an User Equipment UE and at least one external network, referred to as Packet Data Network PDN, via a selected one of mobile network nodes associated with the PDN and referred to as PDN Gateway PDN GW. The method may include support of a nomadic or fixed user in a mode of operation referred to as non-mobile mode of operation wherein the selected PDN GW, referred to as local PDN GW, is co-located with a RAN node serving the UE, based on knowledge of the user's mobility pattern.

Support of nomadic or fixed users in a mobile network

In an embodiment, a Radio Access Network RAN entity, referred to as serving RAN entity, and controlling one or more cells, is configured to:

Paging optimization in a mobile network

An embodiment is a method for support of retrieval and/or reporting and/or triggering the reporting of user location information in a mobile network, wherein said user location information is retrieved and/or reported and/or the reporting of said user location information is triggered, at a granularity of an area referred to as administrative area defined as a set of mobile network related areas, mobile network related areas being defined at mobile network management level, and mobile network related areas being mapped to administrative areas.

Support of retrieval and/or reporting and/or triggering the reporting of user location information in a mobile network

Embodiments of the present invention include a method for WLAN Access Network WLAN-AN selection by an User Equipment UE for access to a mobile network PLMN, said selection including, for an UE roaming in a Visited PLMN VPLMN and requiring a Packet Data Network Gateway PDN-GW in its Home PLMN HPLMN, selection of a WLAN-AN having connectivity to at least one PDN-GW in said HPLMN, based on information on connectivity to at least one PDN-GW in said HPLMN of WLAN-ANs candidate for said selection, referred to as connectivity information.
