Abstract

A computer-implemented network communication method includes receiving, by a network access stratum device, an uplink message sent by a terminal device, in which the uplink message is sent over a persistent connection between the network access stratum device and the terminal device; encapsulating, by the network access stratum device, the uplink message and a session identifier of the persistent connection into a target message; transmitting, by the network access stratum device, the target message to a message forwarding device over a short-term connection between the network access stratum device and the message forwarding device; receiving, by the network access stratum device, from the message forwarding device, a downlink message corresponding to the target message, in which the downlink message includes the session identifier; identifying, by the network access stratum device, the terminal device as a receiving device of the downlink message based on the session identifier; and sending, by the network access stratum device, the downlink message to the terminal device.

First claim

What is claimed is:

1 . A computer-implemented network communication method, comprising:
receiving, by a network access stratum device, an uplink message sent by a terminal device, wherein the uplink message is sent over a persistent connection between the network access stratum device and the terminal device; encapsulating, by the network access stratum device, the uplink message and a session identifier of the persistent connection into a target message; transmitting, by the network access stratum device, the target message to a message forwarding device over a short-term connection between the network access stratum device and the message forwarding device; receiving, by the network access stratum device, from the message forwarding device, a downlink message corresponding to the target message, wherein the downlink message comprises the session identifier; identifying, by the network access stratum device, the terminal device as a receiving device of the downlink message based on the session identifier; and sending, by the network access stratum device, the downlink message to the terminal device.

2 . The computer-implemented method of claim 1 , comprising:
receiving, by the network access stratum device, a heartbeat request transmission sent by the terminal device; obtaining heartbeat response information corresponding to the heartbeat request transmission, the heartbeat response information comprising information about a state of the persistent connection between the network access stratum device and the terminal device; and transmitting the heartbeat response information to the terminal device.

3 . The computer-implemented method of claim 1 , comprising:
determining, by the network access stratum device, that a predetermined heartbeat reporting period is reached; in response to determining that the predetermined heartbeat reporting period is reached, obtaining heartbeat information of the terminal device, the heartbeat information comprising information about a state of the persistent connection between the network access stratum device and the terminal device; and sending the heartbeat information to the terminal device.

4 . The computer-implemented method of claim 1 , wherein receiving the downlink message comprises receiving the downlink message over the short-term connection.

5 . The computer-implemented method of claim 1 , wherein the message forwarding device comprises an Internet of Things hub.

6 . The computer-implemented method of claim 1 , wherein the method comprises:
in response to receiving the uplink message, establishing the short-term connection between the network access stratum device and the message forwarding device.

7 . The computer-implemented method of claim 1 , wherein one or more other terminal devices are persistently connected to the network access stratum device.

8 . A non-transitory, computer-readable medium storing one or more instructions executable by a computer system to perform network communication operations comprising:
receiving, by a network access stratum device, an uplink message sent by a terminal device, wherein the uplink message is sent over a persistent connection between the network access stratum device and the terminal device; encapsulating, by the network access stratum device, the uplink message and a session identifier of the persistent connection into a target message; transmitting, by the network access stratum device, the target message to a message forwarding device over a short-term connection between the network access stratum device and the message forwarding device; receiving, by the network access stratum device, from the message forwarding device, a downlink message corresponding to the target message, wherein the downlink message comprises the session identifier; identifying, by the network access stratum device, the terminal device as a receiving device of the downlink message based on the session identifier; and sending, by the network access stratum device, the downlink message to the terminal device.

9 . The non-transitory, computer-readable medium of claim 8 , wherein the operations comprise:
receiving, by the network access stratum device, a heartbeat request transmission sent by the terminal device; obtaining heartbeat response information corresponding to the heartbeat request transmission, the heartbeat response information comprising information about a state of the persistent connection between the network access stratum device and the terminal device; and transmitting the heartbeat response information to the terminal device.

10 . The non-transitory, computer-readable medium of claim 8 , wherein the operations comprise:
determining, by the network access stratum device, that a predetermined heartbeat reporting period is reached; in response to determining that the predetermined heartbeat reporting period is reached, obtaining heartbeat information of the terminal device, the heartbeat information comprising information about a state of the persistent connection between the network access stratum device and the terminal device; and sending the heartbeat information to the terminal device.

11 . The non-transitory, computer-readable medium of claim 8 , wherein receiving the downlink message comprises receiving the downlink message over the short-term connection.

12 . The non-transitory, computer-readable medium of claim 8 , wherein the message forwarding device comprises an Internet of Things hub.

13 . The non-transitory, computer-readable medium of claim 8 , wherein the operations comprise:
in response to receiving the uplink message, establishing the short-term connection between the network access stratum device and the message forwarding device.

14 . The non-transitory, computer-readable medium of claim 8 , wherein one or more other terminal devices are persistently connected to the network access stratum device.

15 . A computer-implemented system, comprising:
one or more computers; and one or more computer memory devices interoperably coupled with the one or more computers and having tangible, non-transitory, machine-readable media storing one or more instructions that, when executed by the one or more computers, perform one or more network communication operations comprising:
receiving, by a network access stratum device, an uplink message sent by a terminal device, wherein the uplink message is sent over a persistent connection between the network access stratum device and the terminal device;
encapsulating, by the network access stratum device, the uplink message and a session identifier of the persistent connection into a target message;
transmitting, by the network access stratum device, the target message to a message forwarding device over a short-term connection between the network access stratum device and the message forwarding device;
receiving, by the network access stratum device, from the message forwarding device, a downlink message corresponding to the target message, wherein the downlink message comprises the session identifier;
identifying, by the network access stratum device, the terminal device as a receiving device of the downlink message based on the session identifier; and
sending, by the network access stratum device, the downlink message to the terminal device.

16 . The computer-implemented system of claim 15 , wherein the operations comprise:
receiving, by the network access stratum device, a heartbeat request transmission sent by the terminal device; obtaining heartbeat response information corresponding to
