A method, apparatus and computer program product are provided herein to provide service continuity between a Stand-alone Non-Public Network (SNPN) and a Public Land Mobile Network (PLMN). For example, a method is provided that comprises after determining that the user equipment (UE) with the first protocol data unit (PDU) session established in the first SNPN is or will be leaving the coverage area of the first SNPN, causing a request message to be transmitted to the UE, wherein the request message comprises a request to initiate a second PDU session establishment procedure towards a PLMN. The method also includes causing the UE to establish the second PDU session with an internet protocol anchor function of a user plane function in the PLMN via the first SNPN radio access network (RAN) or via the PLMN RAN, wherein the second PDU session is established prior to release of the first PDU session.

Method and apparatus for providing network triggered mobility between a stand-alone non-public network and a public land mobile network

A plurality of interworking functions, which provide interworking between a communication network acting as access network and another communication network, is associated with a plurality of network slices or non-public networks hosted by the other communication network. A user equipment performs connection (S) to a communication network acting as access network, and selects (S) an interworking function of the plurality of interworking functions based on information on a network slice or non-public network hosted by the other communication network, wherein the user equipment is associated with the network slice or non-public network.

Non-3GPP interworking function selection for public network integrated non-public networks

There are provided measures for assisted distributed gateway selection. Such measures exemplarily comprise (as control plane network entity functionality in a mobile network scenario where an access of a terminal to a network is movable between at least two base stations and routable in parallel via at least one local gateway and a centralized gateway) detecting movement of said access of said terminal from a first base station to a second base station, determining that a first network route which is a current network route from said terminal via a first local gateway which is a current local gateway of said at least one local gateway provides less network performance than a second network route from said terminal via a second local gateway of said at least one local gateway based on a result of said detecting, and deciding said second local gateway as a target local gateway for said terminal based on a result of said determining.

Assisted distributed gateway selection

The present invention addresses a method, apparatus and computer program product for accessing a local area scoped network having non-access-stratum procedures, such as a MuLTEfire network, which implement identifying an available access point of the local area scoped network having non-access-stratum procedures, transmitting a message to the access point, indicating a request for retrieving network information, wherein the information are queried from the network before authorization and actually connecting to the network, selecting a service provider of the network based on received network information for binding the network identity to the selected service provider for accessing, and conveying a Non-Access Stratum service request to the network to cause authentication of the user equipment for connecting to the network.

Method, apparatus and computer program product for accessing a local area scoped network having non-access-stratum procedures

It is provided a method, comprising monitoring if a tunnel to a terminal via an untrusted network is to be established, wherein the tunnel is set up only if the terminal is authenticated and authorized; requesting, if the tunnel is to be established, the authentication and authorization and an information on a location of the terminal; providing the information on the location received in response to the request to a gateway.

Location information for untrusted access

Various communication systems may benefit from proper priority control. For example, communication devices in a proximity services user equipment to network relay scenario may benefit from proximity services priority control for multicast traffic. A method can include receiving, at a relay user equipment, an indication of proximity services priority from a remote user equipment. The method can also include applying, by the relay user equipment, a priority based on the indication received from the remote user equipment.

Access mode selection based on user equipment selected access network identity may be useful, for example, with respect to the authentication in third generation partnership project (3GPP) networks of subscribers attaching to a trusted wireless local area network (WLAN) access network (TWAN). A method of access mode selection can include informing, in a request, an authentication server regarding at least one access mode for a user equipment. The method can also include selecting a mode of the at least one access mode to use with respect to the user equipment based on a response received from the authentication server in response to the request.

Access mode selection based on user equipment selected access network identity

An example technique is provided for receiving, by a base station in a wireless network, a priority map that indicates a mapping of a first set of priority classes for one or more radio bearers provided between the base station and a relay user device and a second set of priority classes for one or more proximity services (ProSe) sidelink logical channels provided between the relay user device and a remote user device, and allocating (or scheduling), by the base station based on the priority map, wireless resources to the relay user device to transmit data to the remote user device for one or more of the ProSe sidelink logical channels.

There are provided measures for supporting an authentication to an external packet data network over an untrusted access network, said measures exemplarily comprising authenticating a user equipment to a communication network providing connectivity for the user equipment across an unsecured access network in response to a first authentication request, wherein the authentication request is an authentication request of a key information exchange mechanism and includes authentication data, receiving a second authentication request for authenticating the user equipment towards a packet data network external to the communications network. The measures may further comprise creating a binding update message including the authentication data and identity information of the user received from the user equipment.

External authentication support over an untrusted network

Various communication systems may benefit from the use of relayed packet data connection. Moreover, such communication systems may benefit from methods and systems for the establishment of a packet data network connection for a proximity services user equipment via a relay user equipment. A method can include establishing a packet data network connection between a relay user equipment and a packet data network gateway. The method can also include establishing a relay connection between a proximity services user equipment and the packet data network gateway. The relay connection can be a connection within the packet data network connection.

Establishment of packet data network connection via relay user equipment

A method and apparatus may be configured to determine a network identity that is valid for the first network and a second network. The method may also include assigning the network identity to a user equipment. The method may also providing the network identity to one of the second network and a user equipment. The first network and the second network may be based on different technologies.

User equipment identity valid for heterogeneous networks

Apparatuses and methods are provided by which a second address of user equipment, which is served on a first address in a first network in a first address realm, to be used by the user equipment for a service in a second address realm is detected, the second address is stored together with the first address, and a network policy control element controlling policy in connection with the service in the second address realm is informed about the second address is. In this way, also a single stack user equipment may access services in different address realms.

Enabling multi-realm service access for a single IP stack UE

There is provided a mechanism for establishing a single PDN connection with plural IP addresses and breakout or terminating points. When a communication connection provided with multiple IP addresses via a multi-address bearer connection is established, an indication is prepared for indicating a terminating point represented by a network element of the cellular communication network where data traffic, based on one of the multiple IP addresses, is branched to another network being different to the cellular communication network by means of an IP based communication link The indication element is sent to the communication network by means of a PDCP signaling e.g. as a new PDU type code. In the network, it is decided whether a local receiving network element is indicated as a terminating point, wherein in this case a breakout connection to another network being different to the cellular communication network by the IP based communication link is established.

Mechanism for establishing packet data network connection with multiple IP addresses

The present invention proposes methods, devices and computer program products in relation to enhancements for providing for RAN based LGW selection. Two basic options for the RAN based improved solution are presented for scenarios in which HeNB sends a list of the available LGW addresses/identities and the APNs supported by the different LGWs. According to option 1, if more than one LGW can support a given APN, then the H(e)NB only sends the address of the preferred LGW (e.g., based on local network topology) for the given APN. According to option 2, the HeNB sends priority value (s) with the addresses of the LGWs (for the LGWs only (irrespective of supported APNs) or for (only) the APNs supported by each LGW. Then, the MME/SGSN may consider this priority value (s) at the LGW selection.
