Claim of US Patent No. 10,798,766

1. A multi-connectivity communication method, comprising:determining, by an access network device of a Long Term Evolution (LTE) network, an access network device group for user equipment (UE), wherein the access network device group comprises at least two access network devices of a next generation network, and there is a first connection between the access network device of the LTE network and the UE;
setting up, by the access network device of the LTE network, a second connection for the UE, wherein the second connection is a connection set up between the UE and the access network device of the LTE network through a first access network device in the access network device group, and wherein the setting up comprises:
separately sending, by the access network device of the LTE network, a dual connectivity adding request to each access network device in the access network device group, wherein the dual connectivity adding request requests to add the second connection for the UE;
separately receiving, by the access network device of the LTE network, a dual connectivity adding response from each access network device of the next generation network, wherein the dual connectivity adding response from each access network device of the next generation network comprises configuration information of the respective access network device of the next generation network;
sending, by the access network device of the LTE network, the configuration information of each access network device of the next generation network to the UE;
receiving, by the access network device of the LTE network, a configuration complete message from the UE; and
determining, based on the configuration complete message, that the second connection is successfully set up; and
splitting, by the access network device of the LTE network, data of the UE through the second connection.
