Embodiments of the present invention provide a mobile network communications method, communications apparatus, and communications system. The method includes: receiving, by a transport packet data network gateway, a data packet to be sent to a mobile node, and determining a home packet data network gateway of the mobile node according to IP address information of the mobile node; then sending a data connection establishment request message to the home packet data network gateway, to request to establish a data connection to a base station or a serving gateway at a location of the mobile node; and finally sending the data packet to the base station or the serving gateway through a channel of the data connection, or receiving a data packet that is sent by the base station or the serving gateway through a channel of the data connection.

According to at least one example embodiment, hub breakout roaming enables providing data access to a user network device, subscribed with a home network and roaming into a visited network, by a hub breakout system through the visited network. Upon receiving a request for data access from the visited network, the hub breakout system assigns an IP address to the user network device. The hub breakout system then routes data packets, associated with the data access requested by the user network device, to and from at least one corresponding data source, using the assigned IP address. The data source includes the Internet, a private network associated with home network, or any other service provider entity.

A second network which communicates with a communication system for providing access to a network other than a first network, via the second network, to a wireless terminal on which an identification number for accessing the first network is stored, configured to: receive a connection initiation request on C-plane from the wireless terminal to send the connection initiation request to the communication system, receive a gateway ID of a gateway on U-plane to the network connected to the second network, selected on the communication system based on a network ID of the second network, in response to the connection initiation request, wherein the gateway is within a third network other than the first network, and establish a communication path between the gateway on U-plane designated by the gateway ID.

Technology for user equipment (UE) operable to establish a new packet data network (PDN) connection during handover is disclosed. The UE can receive a radio resource control (RRC) connection reconfiguration message from a source radio base station during a handover procedure. The RRC connection reconfiguration message can include a request for establishment of the new PDN connection between the UE and a target PDN gateway (PGW). The UE can establish the new PDN connection with the target PGW using one or more parameters included in the RRC connection reconfiguration message. The UE can send, to a target radio base station, an RRC connection reconfiguration complete message during the handover procedure that includes an acknowledgement of the establishment of the new PDN connection.

Systems, methods, and instrumentalities to select a distributed gateway (D-GW). A WTRU may be configured to detect a request for an address associated with content. The WTRU may receive an address list associated with the content. The WTRU may select a distributed gateway (D-GW). If an address of a currently connected D-GW is included in the address list, the WTRU may select the currently connected D-GW. If the address of the currently connected D-GW is not in the address list and an address of an anchor D-GW that is not currently connected is included in the address list, the WTRU may select the anchor D-GW that is not currently connected. If the address of the currently connected D-GW is not in the address list and the address of the anchor D-GW that is not currently connected is not in the address list, the WTRU may select the currently connected D-GW.

A technique for implementing an untethered access point (UAP) mesh involves enabling AP-local switching at one or more UAPs of the mesh. A system constructed according to the technique may include an untethered access point (UAP), including: a radio; a backhaul service set identifier (SSID) stored in a computer-readable medium; an anchor access point (AAP) selection engine embodied in a computer-readable medium. In operation, the AAP selection engine may use the radio to attempt to associate with the AAP if a beaconed backhaul SSID matches the stored backhaul SSID. A method according to the technique may include beaconing with a backhaul SSID; acting in concert with an upstream switch as an authenticator for a downstream station that responds to the beacon; providing limited local switching functionality for the downstream station.

Disclosures are a user equipment (UE) registration method, entity, system and a computer storage medium. The method comprises: a common service entity (CSE) in a UE sending an equipment registration request to a machine type communication-inter working function entity (MTC-IWF), wherein the equipment registration request contains an identifier of the UE in an underlying network, an application port identifier of the UE, an identifier of a machine-to-machine/man (M2M) service provider subscribed to by the UE, and an identifier of an application entity (AE) of the M2M service provider.

Embodiments of the present disclosure provide a mobility management method, so as to effectively ensure normal communication between user equipment and a base station without using an anchor device, and ensure continuity of a service between the user equipment and a communication peer end. A specific solution is: establishing, by user equipment, a first substream to a communication peer end, when the user equipment is handed over from a first base station to a second base station, obtaining, by the user equipment, a second IP address when a second gateway and a first gateway are not a same gateway, establishing, by the user equipment, a second substream to the communication peer end after obtaining the second IP address, canceling, by the communication peer end, the first substream after the second substream is established, and releasing, by the first gateway, a first IP address after the first substream is canceled.

A primary connection to a user terminal configured to operate using dual connectivity is maintained. A first control interface is maintained to a first radio node maintaining a secondary connection to the user terminal configured to operate using dual connectivity, the first radio node providing a local gateway for the user terminal. A second control interface is maintained to a core network and a local gateway towards a core network is emulated by providing control plane functions of the local gateway provided by the first radio node towards the core network over the second control interface. Local gateway related control messages are relayed between the core network and the first radio node over the first control interface.

A method for steering a mobile device to a preferred network, such as a Private LTE network or a 5G network, in a scenario in which the coverage area of the preferred network overlaps the coverage area of a non-preferred network. A preferred network list is provisioned into a SIM/eSIM module at the mobile device side. The steering application is hosted at the home network and periodically triggers the home network to request from the visited network a set of values for attributes associated with a current location of the mobile device. Based on these values, the steering application determines whether the mobile device is within the coverage area of the preferred network and, if so, directs the home network to send a cancel location request to the non-preferred visited network, thereby triggering the mobile device to attach to the preferred network.
