Message processing method, apparatus, and system

A method comprising:

• sending, by a first network element, a first message to a second network element, wherein the first message comprises reset flag information and a sequence number;
• using, by the first network element, the sequence number in the first message as a first interaction sequence number of the first network element, and increasing the first interaction sequence number of the first network element by a specified step to obtain a first waiting sequence number of the first network element;
• receiving, by the second network element, the first message from the first network element;
• and
• when the reset flag information is first reset flag information, and the sequence number in the first message is the same as a waiting sequence number of the second network element, processing, by the second network element, the first message using the sequence number in the first message as a second interaction sequence number of the second network element, and increasing the second interaction sequence number of the second network element by the specified step to obtain a second waiting sequence number of the second network element;
• and
• wherein the first interaction sequence number of the first network element indicates a sequence number of a message currently exchanged between the first network element and the second network element, the first waiting sequence number of the first network element indicates a sequence number of a next message for which the first network element is currently waiting, the second interaction sequence number of the second network element indicates the sequence number of the message currently exchanged between the second network element and the first network element, and the second waiting sequence number of the second network element indicates a sequence number of a next message for which the second network element is currently waiting.

An apparatus, comprising:

• a non-transitory memory storage comprising instructions;
• and
• one or more processors in communication with the memory storage, wherein the instructions, when executed by the one or more processors, cause the apparatus to:
• send a first request message to a second network element, wherein the first request message belongs to a first hypertext transfer protocol (HTTP) interaction procedure;
• before receiving a first response message for the first request message, receive a second request message from the second network element, wherein the first response message belongs to the first HTTP interaction procedure, and the second request message belongs to a second HTTP interaction procedure;
• and
• perform an operation on the second request message based on whether the second HTTP interaction procedure is dependent on the first HTTP interaction procedure and whether the second request message is rejectable by the apparatus, or based on priorities of the first HTTP interaction procedure and the second HTTP interaction procedure.
