An access and mobility management function (AMF) is modified with network slice information. First requested network slice information of a protocol data unit session is received from a wireless terminal. Second requested network slice information is generated based on the first requested network slice information of the PDU session and supported network slice information of a radio access network node of the wireless terminal.

Method for slice information update

Systems and methods for wireless communications are disclosed herein. In one embodiment, the system and method are configured to receive, by a mobility management function (AMF) from a network function (NF), slice information including at least one of a quality of service (QoS) profile for a slice or a service area of the slice. The AMF can determine that a wireless communication device is authorized to access a slice based on the service area of the slice. The AMF can send the QoS profile comprising a slice-specific aggregate maximum bit rate (AMBR) specific to the slice to the radio access network.

Method of authorization for network slicing

Provided are a method, apparatus and device for a terminal moving between a 4G network and a 5G network. The method includes: transmitting, by a management device corresponding to a target network, an access accept message, where the access accept message carries an activation indication; and the activation indication is used for indicating a terminal to reactivate a public data network (PDN) connection or a protocol data unit (PDU) session in a source network in the target network, or indicating the terminal that the PDN connection or the PDU session has been activated in the target network.

Method, apparatus and device for allowing terminal to move between 4G and 5G networks

The embodiments of the present disclosure provide a method and an apparatus for connection handling. The method includes: receiving a connection request that requests for establishing or resuming a connection with a base station; and instructing a Non-Access Stratum (NAS) of a terminal to perform a predetermined operation based on an obtained first connection result corresponding to the connection request. In this way, the problems associated with inconsistent operations in the user plane optimization in the related art can be solved and the consistency in operations between the Access Stratum (AS) and NAS of the terminal can be achieved.

Method and apparatus for handling connections

A method for gateway recovery processing and device, the method comprising: a first mobility management unit receiving Packet Data Network (PDN) connection signaling, and triggering a paging procedure for a terminal; in response to determining that the paging procedure fails, the first mobility management unit setting and storing flag information, wherein the flag information is used to indicate that the PDN connection signaling is in a suspended state; and in a case where the terminal moves from a coverage area of the first mobility management unit to a coverage area of a second mobility management unit, the first mobility management unit sending the flag information to the second mobility management unit, wherein the flag information is used for the second mobility management unit to trigger a Serving Gateway (SGW) to send a bearer update request message to a PDN Gateway (PGW).

Gateway recovery processing method and device

A system and method of registration with AMF re-allocation. The system and method includes receiving, by an initial AMF from a wireless communication device via a RAN, a registration request comprising a first device identifier associated with the wireless communication device. The system and method includes determining, by the initial AMF, an identifier type associated with the first device identifier. The system and method includes generating, by the initial AMF, a reroute message comprising a second device identifier. The system and method includes originating, by the initial AMF to the wireless communication device, a security mode command message comprising a redirection criteria or an integrity negotiation algorithm, the security mode command message causes the wireless communication device to set the redirection criteria allowing the wireless communication device to accept a request message that is not integrity protected and return a security mode complete message to the initial AMF.

Method of registration with access and mobility management function re-allocation

A wireless communication method is provided to comprise: receiving, by a first computing device, a notification that a wireless communication device that has previously established a protocol data unit session via a first network access has registered for a second network access; and establishing, by the first computing device, one or more quality of service (QoS) flows for the protocol data unit session for the wireless communication device over the second network access by transmitting, to a second computing device, a message that includes information to associate the one or more quality of service (QoS) flows with the second network access, and wherein the first computing device is configured to carry out a session management function and the second computing device is configured to carry out an access and mobility management function.

Methods and computing device for splitting traffic across multiple accesses

A method for gateway recovery processing and device, the method comprising: in the case where a terminal moves from a first mobility management unit to a second mobility management unit, the second mobility management unit receiving flag information from the first mobility management unit, wherein the flag information being used to indicate that a connection signaling of a packet data network (PDN) is in a suspension state; and the second mobility management unit transmitting the flag information to a serving gateway (SGW), the flag information being used to trigger the SGW to send a bearing update request message to a PGW as a packet data network element. The above technical solution achieves that the PGW is notified when a UE moves to a new mobility management unit, so as to ensure the terminal to receive downlink service.

The present disclosure provides a method for establishing a transmission channel, a Mobility Management Entity (MME), a network element device and a system for establishing a transmission channel. The method includes: obtaining, by a Mobility Management Entity (MME), an identifier of a Service Capability Exposure Function (SCEF) entity; and initiating establishment of a non-Internet Protocol (IP) data transmission channel with the SCEF entity based on the identifier of the SCEF entity.

Method for establishing transmission channel, MME, network element device, system and storage medium

Methods and devices for notifying an authorization update are provided. In a method for notifying an authorization update, a home network Proximity-based Services (ProSe) functional entity of an announcing terminal receives a notification message from a ProSe application server, where the notification message is used for notifying the home network ProSe functional entity of the announcing terminal that authorization information changes (S); and the home network ProSe functional entity of the announcing terminal notifies a home network ProSe functional entity of a monitoring terminal that a ProSe code and/or filter corresponding to the announcing terminal become/becomes invalid or are/is updated (S).

Methods and devices for notifying authorization update

The present document provides a Device to Device ( D2D) service authorization method and apparatus and a home near field communication server. The above method includes: a home near field communication server obtaining a local PLMN list of a location in which a user equipment is currently located and a first PLMN list that a permission of authorization to the user equipment is a condition authorization; performing intersection processing on the local PLMN list and the first PLMN list to obtain a second PLMN list; generating an authorized PLMN list according to PLMNs permitting a D2D authorization to the user equipment in the second PLMN list; and the home near field communication server sending the authorized PLMN list to the user equipment.
