1. A direct connection communication method, comprising:
sending, by a first terminal, a direct connection communication request message to a second terminal, wherein the direct connection communication request message carries a Quality of Service (QoS) parameter of direct connection communication;
receiving, by the first terminal, a direct connection communication response message determined according to the QoS parameter of direct connection communication from the second terminal, wherein the direct connection communication response message is used to indicate that the second terminal accepts or rejects a request from the first terminal; and
establishing, by the first terminal, a direct connection communication connection with the second terminal according to the direct connection communication response message if the direct connection communication response message indicates that the second terminal accepts the request from the first terminal;
wherein before the first terminal sends the direct connection communication request message to the second terminal, the method further comprises:
receiving, by the first terminal, a non-access stratum message sent from an Access control and Mobility management Function (AMF) entity, wherein the non-access stratum message comprises a QoS rule of direct connection communication and/or a QoS parameter of direct connection communication; and
determining, by the first terminal, the QoS parameter of direct connection communication according to the non-access stratum message;
wherein determining, by the first terminal, the QoS parameter of direct connection communication according to the non-access stratum message, comprises:
determining, by the first terminal, the QoS parameter of direct connection communication according to the QoS rule of direct connection communication carried in the non-access stratum message; and
transferring, by the first terminal, the QoS parameter of direct connection communication from non-access stratum to access stratum.
