The present application is at least directed a system for managing a server transition associated with user equipment. The system includes a non-transitory memory and a processor that is operably coupled to the non-transitory memory. The processor is configured to perform the instructions of receiving a relocation request from a first server to switch to another server. The processor is also configured to verify credentials of the first server. The processor also determines whether a first core networking terminating point associated with the first server is appropriate for the other server to communicate with the user equipment. Further, the processor sends a result of the determination to the user equipment.

In one embodiment, a device in a network receives a notification from a neighbor of the device indicative of a child node of the device requesting a parent change from the device to the neighbor. The device updates an existing routing path from the device to the child node to be routed through the neighbor, in response to receiving the notification from the neighbor. The device receives an instruction to remove the updated routing path from the device to the child node through the neighbor. The device removes the updated routing path from the device to the child node, in response to receiving the instruction to remove the updated routing path.

A method is disclosed for providing IP access across packet data network gateways (PGWs), comprising: receiving, from a UE, at a coordinating node, an attach request; sending a request to create a first new session to a first PGW; sending a request to create a second new session to a second PGW; receiving, from the first PGW and at the coordinating node, a first request for policies for the UE; receiving, from the second PGW and at the coordinating node, a second request for policies for the UE; opening a first data tunnel from the coordinating node to the first PGW; opening a second data tunnel from the coordinating node to the second PGW without closing the first data tunnel; and opening a data tunnel between the UE and the coordinating node for providing IP access to both the first PGW and the second PGW.

Applicants disclose an inter-system mobility anchor control point that is adapted to initiate handover of an existing communication connection in an integrated small cell and WiFi (ISW) network. The inter-system mobility anchor control point is communicatively coupled to both an HeNB/LTE network and trusted WLAN access network (TWAN) and adapted to operate as a common control plane entity for both HeNB/LTE and TWAN access. The mobility anchor control point may be a mobility management entity (MME) or an integrated small cell and WLAN gateway (ISW GW). The mobility anchor control point is adapted to request and receive measurement data relating to the operations of the HeNB network and WLAN. Based upon the measurement data, the mobility anchor control point determines whether an existing communication path via one of the HeNB/LTE network and WLAN should be handed over to the other of the networks.

A communication control method and a related network element are provided. The communication control method includes: receiving a control request related to a user terminal that accesses a network through a first base station, and determining, based on the control request, a first service network element providing a service for the user terminal; determining a first forwarding plane network element providing a forwarding service for the user terminal; and establishing a service packet forwarding path between the first service network element and the first forwarding plane network element to transmit a service packet of the user terminal. Technical solutions in embodiments of the present invention provide an end-to-end service packet routing mechanism.

In some embodiments, a non-transitory processor-readable medium includes code to cause a processor to receive at a tunnel server, a data unit addressed to a communication device, and define, a first instance of the data unit and a second instance of the data unit. The first instance of the data unit is sent to the communication device via a first tunnel defined between at least the tunnel server and a first base station associated with a first network. The second instance of the data unit is sent to the communication device via a second tunnel defined between at least the tunnel server and a second base station associated with a second network. The second instance of the data unit is dropped by the communication device when the first instance of the data unit is received before the second instance of the data unit.

Embodiments of the present invention provide a system, method, and device for processing air interface information. An enhanced base station includes: a receiver, configured to receive, through an open interface, an air interface control policy sent by a radio access network controller having an air interface control function of a radio access network; and a processor, configured to process air interface user plane data according to the air interface control policy. The technical solutions provided by the embodiments of the present invention implement separation of a control plane and a user plane of the radio access network through the radio access network controller and the enhanced base station.

One disclosure of the present specification provides a method for supporting service continuity after a terminal performs a handover. The method may comprise: a step of transmitting, when re-assigned from a source user plane (UP) functional node to a target UP functional node in accordance with performing a handover to a target base station, a PDU session creation request message to create a new PDU session with the target UP functional node; a step of receiving a PDU session creation response message including a newly allocated second IP address; a step of transmitting a tunneling request message including information on the newly allocated second IP address and information on a service flow requiring service continuity; and a step of encapsulating a packet, which has been generated with an existing first IP address by an upper layer of the terminal, with a new second IP address by a lower layer of the terminal and transmitting the encapsulated packet to the tunneling entity.

Embodiments of this application relate to the field of communications technologies, and provide a network connection method and an apparatus. The method carried out by a network control element includes: sending a first connection parameter to a terminal, and sending a second connection parameter to a security node, so that a network connection between the terminal and the security node is established by using the first connection parameter and the second connection parameter, where the first connection parameter is used for decrypting data encrypted by using the second connection parameter, correspondingly, the second connection parameter is used for decrypting data encrypted by using the first connection parameter, and the first connection parameter and the second connection parameter each include a security parameter used when the terminal and the security node establish the network connection.

The present application discloses an application migration method in a mobile edge system, a related device, and a system. The method performed by a mobile edge orchestrator includes: obtaining a working index set of a to-be-migrated application on a first mobile edge server, where the working index set includes a migration index set including at least one migration index; determining a target migration solution of the to-be-migrated application based on the working index set and a preset correspondence, which is a correspondence between a migration index set and a migration solution; and sending a migration instruction to a mobile edge platform manager, where the migration instruction carries the target migration solution, and the migration instruction is used to instruct the mobile edge platform manager to migrate, based on the target migration solution, the to-be-migrated application from the first mobile edge server to a second mobile edge server.
