Abstract: A first access network device obtains voice service indication information and sends a first paging message including the voice service indication information to a first terminal. The first access network device receives, from the first terminal, a request message is usable to request to establish or resume an RRC connection. The request message includes indication information usable to indicate that the RRC connection is established or resumed based on a voice service. The first access network device determines, based on the indication information, to enable the first terminal to access a second access network. The first access network device is located in a first access network using a first radio access technology. The second access network uses a second radio access technology, and the second access network supports the first terminal in performing the voice service to reduce communication delay and improve communication quality.
