Terminals and network devices are included in these various systems. Core network parts such as evolved packet system (Evloved PACKET SYSTEM, EPS), 5G system (5 GS), etc. may also be included in the system.

The terminal according to the embodiment of the application can be a device for providing voice and/or data connectivity for a user, a handheld device with a wireless connection function, or other processing devices connected to a wireless modem, etc. The names of terminals may also be different in different systems, for example in a 5G system, a terminal may be referred to as User Equipment (UE). The wireless terminal may communicate with one or more Core Networks (CNs) via a radio access Network (Radio Access Network, RAN), which may be mobile terminals, such as mobile phones (or "cellular" phones) and computers with mobile terminals, e.g., portable, pocket, hand-held, computer-built-in or vehicle-mounted mobile devices that exchange voice and/or data with the radio access Network. Such as Personal communication services (Personal Communication Service, PCS) phones, cordless phones, session initiation protocol (Session Initiated Protocol, SIP) phones, wireless local loop (Wireless Local Loop, WLL) stations, personal digital assistants (Personal DIGITAL ASSISTANT, PDA) and the like. A wireless terminal may also be referred to as a system, subscriber unit (subscriber unit), subscriber station (subscriber station), mobile station (mobile), remote station (remote station), access point (access point), remote terminal (remote terminal), access terminal (ACCESS TERMINAL), user terminal (user terminal), user agent (user agent), user device (user equipment), and embodiments of the present application are not limited in this respect.

The nodes (e.g., the primary node and the secondary node) involved in the embodiments of the present application are network devices. For example, a node may be a base station, which may include a plurality of cells serving a terminal. A base station may also be called an access point, or may be a device in an access network that communicates over the air-interface, through one or more sectors, with wireless terminals, or other names, depending on the particular application. The network device may be configured to exchange received air frames with internet protocol (Internet Protocol, IP) packets as a router between the wireless terminal and the rest of the access network, which may include an Internet Protocol (IP) communication network. The network device may also coordinate attribute management for the air interface. For example, the network device according to the embodiment of the present application may be a network device (Base Transceiver Station, BTS) in a global system for mobile communications (Global System for Mobile communications, GSM) or code division multiple access (Code Division Multiple Access, CDMA), a network device (NodeB) in a wideband code division multiple access (Wide-band Code Division Multiple Access, WCDMA), an evolved network device (evolutional Node B, eNB or e-NodeB) in a long term evolution (long term evolution, LTE) system, a 5G base station (gNB) in a 5G network architecture (next generation system), a home evolved base station (Home evolved Node B, heNB), a relay node (relay node), a home base station (femto), a pico base station (pico), etc., which are not limited in the embodiment of the present application.

Currently, the secondary base station sends a reconfiguration message to the terminal, and the terminal completes downlink synchronization and triggers random access based on the reconfiguration message to access the target primary cell (PRIMARY CELL, PCELL) or the target primary secondary cell (Primary Secondary Cell, PSCell).

In the related art, if the secondary base station does not participate in the primary base station in the process of sending the reconfiguration message to the terminal, the information on the network side and the UE side are asymmetric, the network side cannot determine which type of reconfiguration is performed (synchronous reconfiguration or asynchronous reconfiguration), and cannot determine whether the related configuration (conditional reconfiguration configuration information) needs to be deleted, so that the situation that the information on the network side and the UE side is asymmetric may occur, the reconfiguration fails, and the reestablishment is triggered.

The embodiment of the application provides a communication method and a communication device, which are used for solving the problems that information on a network side and UE side is asymmetric and reconfiguration failure is caused. The method and the device are based on the same application, and because the principles of solving the problems by the method and the device are similar, the implementation of the device and the method can be referred to each other, and the repetition is not repeated.

Further, the master node reserves the conditional reconfiguration configuration information under the condition that the indication information is received.

The terminal then deletes the conditional reconfiguration configuration information. In order to make the network side and terminal side information symmetrical, the terminal may send indication information to the master node, and instruct the master node to delete the conditional reconfiguration configuration information through the indication information.

In the method provided by the embodiment of the application, the terminal sends the indication information to the main node under the condition of receiving the reconfiguration message, so that the main node can process the conditional reconfiguration information based on the indication information, thereby enabling the information of the network side and the terminal side to be symmetrical, ensuring the success of reconfiguration and avoiding triggering reconstruction.
