    Abstract: Embodiments of the prevent invention provide a network access authentication method and device. The method comprises: receiving an authentication request message sent by a first serving network, wherein the authentication request message carries a user equipment pseudonym identifier generated by a user equipment; determining whether a local user equipment pseudonym identifier is asynchronous with the user equipment pseudonym identifier generated by the user equipment; and obtaining, if the determination result is yes, an encrypted international mobile subscriber identity (IMSI) to carry out network access authentication on the user equipment. The embodiments of the present invention can solve the problem that a network access process in the related art does not provide a processing method for the case where the user equipment pseudonym identifier in the user equipment is asynchronous with the user equipment pseudonym identifier in a home network.

    Abstract: The invention relates to the field of communication, and provides a method and a device for configuring a redundant PDU session. The method includes: obtaining first redundancy indication information for establishing or modifying the PDU session and/or a QoS flow; and configuring the redundant PDU session and/or a redundant QoS flow on a corresponding RAN node, according to the first redundancy indication information. In the present invention, establishing and modifying of a user plane multi-connectivity can be realized by obtaining the redundancy indication information for establishing or modifying the PDU session and/or the QoS flow, and configuring the redundant PDU session and/or the QoS flow to the corresponding RAN node according to the redundancy indication information.

    Abstract: Provided are a key derivation method and device. The method includes: acquiring a slice identifier corresponding to a network slice to which a user equipment is currently attached, where the slice identifier uniquely identifies the network slice; and transmitting the slice identifier to a designated communication device. The slice identifier is configured to instruct the designated communication device to derive, according to the slice identifier, an intermediate key required by the network slice. By means of the technical solution described above, the problem in the related art that a slice function cannot be implemented normally due to the fact that different network slices probably use the same intermediate key may be solved, and different network slices may correspond to different intermediate keys, thereby avoiding a case that the slicing function cannot be implemented normally caused by allocating the same intermediate key to different network slices.

    Abstract: 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.
