Description

Communication method and device Technical Field The embodiment of the application relates to the technical field of communication, in particular to a communication method and device. Background The disability (reduced capability, redCap) is a fifth generation mobile communications (5th generation mobile communication technology,5G) technology defined by the third generation partnership project (3rd generation partnership project,3GPP) standardization organization, also known as lightweight 5G. RedCap is to reduce the capacity of the terminal by reducing the bandwidth, the number of transmit-receive antennas, reducing the speed, adjusting the modulation mode, introducing the half duplex mode and the like on the premise of ensuring the application requirements and the performance, and reduce the complexity of the terminal, so as to achieve a series of purposes of reducing the cost, the power consumption, prolonging the service life and the like of the terminal, and RedCap is more beneficial to the popularity and the commercial property of the 5G network. In the related art, a RedCap terminal can only work normally in a new air interface (NR) cell or a non-NR cell (such as a long term evolution (long term evolution, LTE) cell) supporting RedCap, and a RedCap terminal may switch to an NR cell not supporting RedCap during a process of moving from the non-NR cell to the NR cell, thereby causing a failure of the normal operation of the RedCap terminal and a service interruption of the RedCap terminal. Disclosure of Invention The embodiment of the application provides a communication method and a communication device, which are used for improving service continuity of RedCap terminals. In order to achieve the above purpose, the embodiment of the application adopts the following technical scheme: In a first aspect, an embodiment of the present application provides a communication method, where the method includes determining whether at least one NR neighbor cell of a current camping cell supports RedCap or eRedCap in an idle state, and reporting a first indication that no support RedCap or eRedCap is supported to a first network device in a connected state if each neighbor cell of the at least one NR neighbor cell does not support RedCap or eRedCap, where the first network device is a network device corresponding to the current camping cell. According to the scheme provided by the embodiment of the application, under the condition that the NR neighbor cells of the current resident cell do not support RedCap (eRedCap) technology, the RedCap (eRedCap) terminal reports the capacity of non-RedCap (not eRedCap) to the network equipment corresponding to the current resident cell, so that the RedCap (eRedCap) terminal is switched to the NR cell which does not support RedCap (eRedCap) technology by the identity of the non-RedCap (not eRedCap) terminal and normally works in the NR cell which does not support RedCap (eRedCap) technology according to the non-RedCap (not eRedCap) terminal, and service interruption caused by the fact that the RedCap (eRedCap) terminal is switched to the NR cell which does not support RedCap (eRedCap) technology by the identity of the RedCap (eRedCap) terminal and cannot normally work is avoided, and service continuity of the RedCap (eRedCap) terminal is improved. In one possible implementation manner, the method may switch from the current camping cell to a target cell in the connected state, and report the first indication to a second network device, where the second network device is a network device corresponding to the target cell. It can be understood that after the RedCap terminal is switched to the NR cell that does not support RedCap, the RedCap terminal reports the first indication to the second network device corresponding to the NR cell that does not support RedCap, so that the NR cell that does not support RedCap under the second network device can treat the RedCap terminal as a non-RedCap terminal, so that the RedCap terminal can normally work in the NR cell that does not support RedCap according to the non-RedCap terminal, thereby guaranteeing service continuity of the RedCap terminal. In a possible implementation manner, if neighbor cell support RedCap or eRedCap exists in the at least one NR neighbor cell, reporting a second indication of support RedCap or eRedCap to the first network device in the connected state, performing radio resource control (Radio Resource Contro, RRC) reestablishment to access an NR cell that does not support RedCap or eRedCap, and reporting the first indication to a third network device, where the third network device is a network device corresponding to the NR cell. It can be appreciated that, in the case that the NR neighbor of the current camping cell has a neighbor cell supporting RedCap, the RedCap terminal may report RedCap capability to the network device corresponding to the current camping cell, so that the RedCap terminal accesses the NR cell
