Problems solved by technology

On the other hand, many M2M services are non-real-time, such as smart meter reading, environmental temperature and humidity monitoring, etc.
If this kind of business is also carried out in real time like H2H communication, it is very likely to occupy a large amount of air interface and network resources, causing network congestion, wh

Example Embodiment

[0026] Method embodiment one

[0027] Such as figure 1 As shown, the flow of the embodiment of the method for triggering terminal communication on the network side of the present invention mainly includes the following steps:

[0028] Step 102: The network side device generates a trigger command and sends it to the terminal.

[0029] Step 104: The terminal establishes a connection with the network side according to the received trigger command, and sends a connection establishment request signaling to the network side device;

[0030] Step 106: The network side device sends a connection establishment response message to the terminal through the connection establishment request;

[0031] Step 108: After the connection is successfully established, the terminal uploads service data to the network side.

[0032] In this embodiment, the trigger command can be issued to the terminal in the following three ways. These three situations are described in detail below:

[0033] (1) The trigger comm...

Example Embodiment

[0045] Method embodiment two

[0046] Take the LTE system as an example, figure 2 This is the specific process of another embodiment of the method for triggering terminal communication on the network side when the terminal is a UE and the network side device is an eNB in ​​this embodiment. Such as figure 2 As shown, the main steps are as follows:

[0047] 1. The eNB sends a trigger command to the UE to trigger the UE to start communication;

[0048] 2. The UE uses MSG1 signaling to send a random access preamble (RA preamble) to the eNB to let the eNB know that there is a terminal trying to establish a connection with the base station;

[0049] 3. The eNB allocates corresponding resources according to the confirmed preamble and sends a random access response message (RA Response) to the UE using MSG2 signaling, carrying the time-advance message, and the allocated uplink resources;

[0050] 4. The UE sends an RRC connection establishment request (Radio Resource Control Request) to the...

Abstract

The invention discloses a method, device and system for triggering terminal communication on the network side. A method for triggering terminal communication by the network side includes: the terminal receives a trigger command sent by the network side; the terminal establishes a connection with the network side according to the trigger command and uploads service data to the network side. The method, device and system for triggering terminal communication on the network side of the present invention trigger the terminal to initiate communication through the network side according to the utilization of network resources, thereby avoiding resource shortage and network congestion caused by a large number of simultaneous communications, and avoid affecting the quality of instant communication such as H2H , It can also make full use of the idle time resources of the network and improve the utilization efficiency of the network.

Description

technical field [0001] The present invention relates to a wireless communication technology, in particular to a method, device and system for triggering terminal communication on the network side. Background technique [0002] In the current mobile communication system, taking the LTE system as an example, a typical communication process starts through the following steps: [0003] (1) The calling terminal initiates a connection establishment request; [0004] (2) The network side route searches for the called terminal; [0005] (3) The MME where the called party is located generates a paging message and sends it to the eNB where the called party is located; [0006] (4) The eNB where the called party is located sends the paging message to the called terminal on the Paging Occasion; [0007] (5) The called terminal establishes a connection with the network and starts the communication process. [0008] Since the current business is mainly for Human-to-Human communication...
