Provided are a network handover method and apparatus, a device, and a storage medium. The method is applied to a first communication node and includes: a handover required message is sent to a core network, where the handover required message carries reference information of UE context at a source side; and a handover control message sent by the core network is received, where the handover control message carries information for maintaining the UE context at the source side, and the information for maintaining the UE context at the source side is used for instructing a network node at the source side not to release resources used by a UE, and the information for maintaining the UE context at the source side is determined by the reference information of the UE context at the source side.

Network handover method and apparatus, device, and storage medium

Provided are a data radio bearer control method, device, and system for a multi-connection system. The data radio bearer control method for a multi-connection system comprises: establishing a split protocol data unit session comprising M quality of service flows, the M quality of service flows being respectively established on N radio access network nodes, wherein one of the N radio access network nodes is a master node, and N−1 radio access network nodes other than the master node among the N radio access network nodes are secondary nodes, M and N are positive integers, and M≥2 and N≥2; and establishing a default data radio bearer for the split protocol data unit session, and configuring the default data radio bearer on any one of the radio access network nodes.

Data radio bearer control method, device and system for multi-connection system

Provided are a redundant session establishment method and apparatus, a radio bearer establishment method and apparatus, a node, a terminal and a medium. The redundant session establishment method includes: generating redundant user plane resource information, and transmitting the redundant user plane resource information to a master node; and establishing a redundant session corresponding to a redundant session request in a redundant user plane resource according to the redundant session request from the master node, where the redundant session request is a request generated by the master node according to the redundant user plane resource information.

Redundant session establishment method and apparatus, radio bearer establishment method and apparatus, and nodes, terminal, and medium

Method, device and computer program product for wireless communication are provided. A method includes: transmitting, by a first wireless communication node, a control message to a second wireless communication node, to control the second wireless communication node to instruct a wireless communication terminal to enter a radio resource control, RRC, inactive mode and transmitting at least one small data transmission, SDT, configuration to the wireless communication terminal.

Method, device and computer program product for wireless communication

proviced is an authentication method based on a GBA, and the method includes: a BSF receives an initialization request message sent by a UE, wherein the initialization request message carries a first identifier of the UE, and the first identifier comprises at least one of the following: a SUCI, an identifier converted from the SUCI, and a TMPI associated with the subscriber identity; the BSF acquires an AV of the UE according to the first ID; the BSF completes GBA authentication with the UE according to the acquired AV. In this way, the privacy of the SUPI is protected for the UE, and the SUCI or the identifier converted from the SUCI is used to perform the bootstrapping process of the GBA, thereby improving the security of the GBA authentication process.

Authentication method based on GBA, and device thereof

Provided is a network equipment and an authentication and key management method for the same. The network equipment generates a Network Key (NK); the network equipment performs authentication protocol interaction with opposite communication equipment, and calculates a Basic Session Key (BSK) according to parameters for the authentication protocol interaction and the NK; and the network equipment calculates link Encryption Keys (EKs) used respectively for Media Access Control (MAC) and Physical (PHY) layers using various access technologies according to the BSK, and provides the EKs for respective MAC and PHY layer function modules. With the disclosure, the legality of the equipment is verified by performing an authentication process on the heterogeneous network equipments in one pass, and keys in various MAC layer technologies are managed in a unified way.

Network equipment and authentication and key management method for same

A method and a device for an optical power budget in a passive optical network are disclosed in the present invention, wherein said method includes: acquiring a corresponding minimum optical link loss according to a transmission requirement of a passive optical network with a large splitting ratio or long distance (); selecting an optical transmitter with large power and an optical receiver with high sensitivity as a combination of an optical transmitter of an Optical Line Terminal (OLT) and an optical receiver of an Optical Network Unit (ONU) in an optical link, as well as a combination of an optical receiver of the OLT and an optical transmitter of the ONU in the optical link according to the minimum optical link loss to compose a passive optical network system comprising the OLT, an Optical Distribution Network (ODN), and ONUs connected in sequence ().
