Abstract

A wireless communication method and device are provided. The method includes: receiving, by a terminal device, first indication information indicating that the terminal device and a first Public Land Mobile Network (PLMN) are capable of interworking with each other. With the first indication information, the terminal device and the first PLMN can interwork with each other. That is, with the first indication information, the terminal device can access an IMS in the first PLMN. It is possible to not only enable the terminal device in an NPN to be connected to the IMS, but also avoid separate deployment of the IMS in the NPN, such that the network deployment cost and system complexity can be reduced.
