Disclosed are methods, devices and systems for detecting data traffic path change of UE when it is being served by an Internet application instance running on a mobile edge host, and moves to the coverage area of another mobile edge host in mobile edge computing system. One exemplary method includes receiving an application resource request for a cloud-computing services from a user equipment (UE), and allocating resources at a mobile edge computing platform to the application resource request in lieu of a server of the cloud-computing services that is reachable via an internet connection. Examples of the disclosed technology may rely on packet header information in downlink or uplink traffic received by mobile edge host, and may be a detection method independent of the signaling notification in the underlying bearer network.

This disclosure relates to techniques for providing a multipath transmission control protocol proxy in a cellular network. A wireless device may establish a wireless link with a cellular network. The wireless device may provide an indication that the wireless device is multipath transmission control protocol (MPTCP) capable to a core network entity of the cellular network. The wireless device may receive MPTCP proxy information for a MPTCP proxy comprised in the cellular network from the core network entity. The MPTCP proxy information may include MPTCP server IP address and port information. The wireless device may establish a first MPTCP flow with the MPTCP proxy comprised in the cellular network via the wireless link.

This disclosure relates generally to cloud radio access network (C-RAN), and more particularly to X2-messaging in the C-RAN. The method may include receiving, by a control unit in the CRAN, in the C-RAN, a request from a first virtual eNodeB (eNB) associated with a source eNodeB (eNB) to establish a X2 interface with each virtual eNB associated with a set of neighbor eNBs. A second virtual eNB associated with a target eNB may be selected from the virtual eNBs associated with the set of neighbor eNBs. A check may be made to determine whether the first virtual eNB and the second virtual eNB associated with the target eNB are co-located on same datacenter in the C-RAN. At least one X2 message may be transmitted between the first virtual eNB and the second virtual eNB that are co-located on the datacenter based on eNB information accessed from a shared storage.

Embodiments of this application disclose a cell access method and a device, to provide a network slice service area identifier and network slice configuration information for a terminal device, so that the terminal device accesses a target cell. The method in the embodiments of this application includes: obtaining, by a terminal device, a network slice service area identifier from a serving access network device corresponding to a serving cell in which the terminal device is located, where the network slice service area identifier is used to indicate an area served by a network slice; determining, by the terminal device, a target cell based on network slice configuration information and the network slice service area identifier, where the network slice configuration information includes a correspondence among a network slice, an area, and a service; and accessing, by the terminal device, the target cell.

To provide a communication control means for establishing a session between a terminal apparatus and a network in a network-initiated manner and/or a connection control means for supporting service continuity and/or a session establishment control means for supporting service continuity and/or a communication control means for service continuity, and the like. These provide a communication control method for establishing an optimal session for service continuity through which service is continued by switching between sessions for communication, an optimal communication control method for service continuity, and the like.

An inter-network change method and apparatus, and a related device are disclosed. In the inter-network change method, a terminal determines second network slice information to which first network slice information is mapped, where the first network slice information is information about a first network slice accessed by the terminal, the second network slice information is information about a second network slice, the first network slice is a network slice in a first network, and the second network slice is a network slice in a second network. The terminal sends a request message to the second network and receives an accept message returned by the second network, so that the terminal accesses a network slice identified by network slice information accepted by the second network. It can be learned that embodiments of the present invention can implement a handover operation between network slices of different networks.

A wireless communication network serves a wireless User Equipment (UE) over a working network slice and a protect network slice. The wireless communication network receives UE capability data from the wireless UE that indicates the working network slice and the protect network slice. The wireless communication network determines UE context for the working network slice and for the protect network slice. The wireless communication network exchanges initial user data with the wireless UE over the working network slice based on the UE context. The wireless communication network exchanges additional user data with the wireless UE over the protect network slice based on the UE context when performance of the working network slice triggers a slice switch based on the UE context.

The present disclosure relates to an electronic device, a communication method and a storage medium in a wireless communication system. There is provided an electronic device for a network control device, comprising a processing circuitry configured to: interact with one or more neighbor cells of a user equipment (UE) to acquire support information on network slice type suitable for the UE fed back by each of the neighbor cells; based on the support information, evaluate a service capability metric for each of the neighbor cells with respect to said network slice type; and at least based on the service capability metric, determine a selection priority of each of the neighbor cells for the UE.

Aspects relate to wireless communication where a master node (MN) or a secondary node (SN) may initiate a conditional addition of a primary secondary cell (PSCell) or a conditional change from one PSCell to another PSCell. Each candidate target PSCell may provide information to be used by the MN to generate a conditional PSCell addition (CPA) configuration or a conditional PSCell change (CPC) configuration that is sent to a user equipment (UE). This information may indicate an execution condition for each candidate target PSCell and/or radio bearers that each candidate target PSCell supports or does not support. An MN may modify a master cell group (MCG) configuration for a PSCell based on information received from a target SN with an secondary cell group (SCG) configuration for the PSCell. The MN may transmit a CPA or CPC configuration including the modified MCG configuration and the SCG configuration to the UE.

Systems and methods for network slice continuity in handover of a communication network are provided. In some embodiments, a User Equipment (UE) is configured to receive, from a network node on a first cell, a first message comprising an indication of at least one cell that supports a particular network slice and engage in a handover operation based on the 5 indication comprised in the received first message. In some embodiments, a network node is configured to sending, to a UE on a first cell, a first message comprising an identification of at least one cell that supports a particular network slice.
