Communication method and communication apparatus

A communication apparatus, comprising:

• processor-readable memory;
• and
• processing circuitry, the processing circuitry providing:
• a communication protocol module configured to:
• send a first request to a mobility management network element, wherein the first request is a request to establish a first protocol data unit (PDU) session for a first data network;
• receive a first response from a first session management network element, and
• send a first notification to a Quick User Datagram Protocol Internet Connections (QUIC) module after receiving the first response, wherein the first response indicates that the first PDU session is successfully established and comprises a first IP address of the communication apparatus, and wherein the first notification comprises the first IP address;
• and
• the QUIC module, which is configured to:
• receive the first notification from the communication protocol module,
• send a second request to an application server of the first data network after receiving the first notification, wherein the second request is a request to establish a first QUIC connection, wherein the second request comprises a first connection identifier that identifies the first QUIC connection, wherein the first connection identifier is allocated by the QUIC module to the first QUIC connection, and wherein the first IP address is an IP address on a communication apparatus side of the first QUIC connection;
• and
• receive a second response from the application server, wherein the second response indicates that the first QUIC connection is successfully established, and wherein the second response comprises the first connection identifier.
