Description
Technical Field
The invention relates to the field of communication of the Internet of things, in particular to a long connection method of an NB-IOT communication terminal.
Background
For NB-IOT communication terminals, some application scenarios require that the NB-IOT communication terminals can quickly respond to a control instruction of a server, and the conventional implementation manner is to maintain a long connection with the server by periodically sending heartbeat packets to the server through the NB-IOT communication terminals, which causes the following problems: because the network bandwidth of the NB-IOT is very small, when a plurality of terminals in a cell simultaneously transmit heartbeat packets, it is very likely that terminal data transmission fails due to insufficient network concurrent capacity, and even a problem of network drop and severe network congestion may occur.
There are two reasons for NB-IOT drop: (1) from the perspective of the radio access network, because the NB-IOT network introduces the PSM mode, after the terminal enters the PSM state, the connection between the terminal and the network is disconnected, and at this time, the data terminal issued by any upper application server cannot receive the data terminal. (2) The terminal data finally enters a public network through a PDN gateway (P-GW) and is transmitted to an upper application server; due to the IPV4 resource limitation, it is impossible for all terminals to use the IP of the independent public network under normal conditions, if the NB-IOT communication terminal does not interact with the server for a certain time, the PDN gateway (P-GW) can recycle the IP resource and allocate the IP resource to other services for use, so that the NB-IOT communication terminal is disconnected with the server.
Therefore, a long connection method for an NB-IOT communication terminal is needed to solve the problem that when the existing NB-IOT communication terminal communicates with a server, data transmission fails due to insufficient network concurrent capacity, and even a terminal may drop the network, and the network is seriously blocked.

(3) the mobile core network allocates a private network IP according to the APN carried by the NB-IOT communication terminal;
(4) the NB-IOT communication terminal establishes long connection with the server through the private network IP.
Preferably, the step (2) specifically comprises:
(21) after the NB-IOT communication terminal and the server complete data interaction, the base station disconnects RRC connection, so that the NB-IOT communication terminal is in an IDLE state;
(22) and the NB-IOT communication terminal periodically monitors network paging in an IDLE state, so that the NB-IOT communication terminal and the base station keep long connection.
