1. A congestion processing method, comprising:
receiving, by an access network device, a first message transmitted by a source core network device, wherein the first message is used for indicating that the source core network device is overloaded; and
transmitting, by the access network device, a second message to a terminal device, wherein the second message is used for instructing the terminal device to release a first connection and establish, with the access network device, a second connection related to a target core network device, wherein the first connection is a connection established between the terminal device and the access network device and related to the source core network device, wherein the target core network device and the source core network device support different communication systems respectively;
wherein the second message comprises second indication information, wherein the second indication information is used for indicating a type of the target core network device;
wherein the source core network device is a core network device in an LTE system, and the target core network device is a core network device in a 5G system; or the target core network device is a core network device in the LTE system, and the source core network device is a core network device in the 5G system.
