Communication method, equipment, system, and computer storage medium

1. A communication method, comprising:

establishing, by a first network node based on an initial stream control transmission protocol (SCTP) association, an SCTP association pool associating the first network node with a second network node;

selecting, by the first network node, from the SCTP association pool, an SCTP association for first signaling transmission; and

transmitting, by the first network node, the first signaling to the second network node via the selected SCTP association,

wherein establishing the SCTP association pool comprises:

establishing, by the first network node, the initial SCTP association associating the first network node with the second network node; and

transmitting, by the first network node, second signaling to the second network node to add one or more SCTP associations to the initial SCTP association, the second signaling including application protocol layer update signaling carrying a list of the one or more SCTP associations to be added.

2. The communication method of claim 1 , wherein the application protocol layer update signaling includes a core network configuration update message.

3. The communication method of claim 1 , further comprising:

sending, by the first network node, an update request message to the second network node, wherein the update request message includes instructions to delete one or more SCTP associations; and

receiving, by the first network node, a response message from the second network node.

4. A communication method, comprising:

establishing, by a second network node based on an initial stream control transmission protocol (SCTP) association, an SCTP association pool associating the second network node with a first network node; and

receiving, by the second network node, first signaling from the first network node via an SCTP association of the SCTP association pool, the SCTP association being selected by the first network node,

wherein establishing the SCTP association pool comprises:

establishing, by the second network node, the initial SCTP association associating the first network node with the second network node; and

receiving, by the second network node, second signaling from the first network node to add one or more SCTP associations to the initial SCTP association, the second signaling including application protocol layer update signaling carrying a list of the one or more SCTP associations to be added.

5. The communication method of claim 4 , wherein the application protocol layer update signaling includes a core network configuration update message.

6. The communication method of claim 4 , further comprising:

receiving, by the second network node from the first network node, an update request message, wherein the update request message includes instructions to delete one or more SCTP associations; and

transmitting, by the second network node in response to receiving the update request message, a response message to the first network node.

7. A non-transitory computer-readable storage medium, which is configured to store computer programs, wherein the computer programs are configured to, when executed by a processor, implement steps of the method of claim 1 .

8. A non-transitory computer-readable storage medium, which is configured to store computer programs, wherein the computer programs are configured to, when executed by a processor, implement steps of the method of claim 2 .

9. A non-transitory computer-readable storage medium, which is configured to store computer programs, wherein the computer programs are configured to, when executed by a processor, implement steps of the method of claim 3 .

10. A non-transitory computer-readable storage medium, which is configured to store computer programs, wherein the computer programs are configured to, when executed by a processor, implement steps of the method of claim 4 .

11. A non-transitory computer-readable storage medium, which is configured to store computer programs, wherein the computer programs are configured to, when executed by a processor, implement steps of the method of claim 5 .

12. A non-transitory computer-readable storage medium, which is configured to store computer programs, wherein the computer programs are configured to, when executed by a processor, implement steps of the method of claim 6 .

13. A network device comprising:

at least one processor configured to:

establish, based on an initial stream control transmission protocol (SCTP) association, an SCTP association pool associating the network device with a second network device;

select from the SCTP association pool, an SCTP association for first signaling transmission; and

transmit the first signaling to the second network device via the selected SCTP association,

wherein in establishing the SCTP association pool, the at least one processor is configured to:

establish, by the first network node, the initial SCTP association associating the network device with the second network device; and

transmit second signaling to the second network device to add one or more SCTP associations to the initial SCTP association, the second signaling including application protocol layer update signaling carrying a list of the one or more SCTP associations to be added.

14. A network device comprising:

at least one processor configured to:

establish, based on an initial stream control transmission protocol (SCTP) association, an SCTP association pool associating the network device with a second network device; and

receive first signaling from the second network device via an SCTP association of the SCTP association pool, the SCTP association selected by the second network device,

wherein in establishing the SCTP association pool, the at least one processor is configured to:

establish the initial SCTP association associating the second network device with the second network device; and

receive second signaling from the second network device to add one or more SCTP associations to the initial SCTP association, the second signaling including application protocol layer update signaling carrying a list of the one or more SCTP associations to be added.
