Abstract: Provided are a system for implementing multiple Radio Access Networks (RANs) convergence and a method thereof in the present invention. The method includes: an anchor RAN establishes a connection with a User Equipment (UE); the anchor receives a RAB establishment request from a Core Network (CN); the anchor RAN selects an auxiliary RAN; the anchor RAN sends quality of service (QoS) parameters to the auxiliary RAN, so that the auxiliary RAN establishes a connection with the UE according to the QoS parameters, while the anchor RAN keep the connection with the UE. With the methods provided in embodiments for the present invention, multiple RANs convergence is implemented, and the UE establishes connections with the anchor RAN and the auxiliary RAN at the same time, so as to improve the peak rate of the UE.

Abstract: A communication method and apparatus are provided, so that an access network device can configure an initial hyper frame number (HFN) and a reference sequence number (SN) for a terminal device in time when no data packet is received from a core network device. The method includes: A first core network device obtains an initial multicast/broadcast service (MBS) quality of service flow identifier (QFI) SN corresponding to a first MBS session, and sends the initial MBS QFI SN in a first procedure. The first procedure is a procedure before a the 1st data packet of the first MBS session is sent to an access network device. After receiving the initial MBS QFI SN in the first procedure, the access network device may determine an initial HFN and a reference SN based on the initial MBS QFI SN, and send the initial HFN and the reference SN to a terminal device.

Abstract: Embodiments of this application disclose a method for waking up a terminal device in a communication network, an apparatus, and a readable storage medium. The method includes: after a terminal device enters an idle state or an inactive state, when the terminal device detects that a doze condition is met, the terminal device enters a doze state from the idle state or the inactive state. During a first time period after the terminal device enters the doze state, if the terminal device does not receive wake-up information or detects that signal quality of the wake-up information is less than or equal to a first threshold, the terminal device enters a wake-up state from the doze state.

Abstract: A data transmission method includes receiving, by a first access network device, local service indication information and a service identifier from a core network device. The local service indication information indicates that a service to which a data packet of a first session belongs is a local service. The data transmission method also includes sending, by the first access network device, third indication information to a second access network device. The third indication information indicates that the service is the local service.

Abstract: A coordinated transmission control method, apparatus, and system. A primary access point and a secondary access point determine whether to perform coordinated transmission through inter-cell configuration parameter sharing and based on a dual decision condition of an interference test. An anti-interference beamforming manner is determined based on a specific cell configuration parameter, and whether to perform coordinated transmission is determined with reference to the dual decision condition of the interference test, wherein the primary and secondary access points learn an interference status in advance to prevent unnecessary retransmission resulting from interference caused during actual coordinated transmission.

Abstract: A method includes a first access network device that sends first indication information to a second access network device. The first indication information indicates information about a current active BWP and/or transmission rate information of a terminal device on the first access network device. The second access network device determines information about a first-time active BWP and/or BWP configuration information of the terminal device on the second access network device based on the first indication information. The method may be used to enable the second access network device to determine the appropriate information about the first-time active BWP and/or the appropriate BWP configuration information of the terminal device on the second access network device. In this way, service interruption caused by switching of an active BWP is reduced, and/or service interruption caused by changing of a BWP configuration is reduced.
