embodiment of the method one
As shown in Figure 1, the embodiment of the method flow process of network side triggering terminal of the present invention communication mainly comprises the following steps:
Step 102, network equipment generates trigger command and sends to terminal,
Step 104, terminal connects according to the trigger command and the network side that receive, sends to connect to set up demand signalling to network equipment;
Step 106, network equipment is set up request by this connection, sends to connect to set up response message to terminal;
Step 108, after connection is successfully established, terminal is uploaded business datum to network side.
In the present embodiment, trigger command can be issued in terminal by following three kinds of modes, below these three kinds of situations is specifically described:
(1) trigger command is arranged in Paging message
In Paging message, add new mark, i.e. trigger command, for notification terminal reported data, instead of does called.This trigger command is the identify label ID of notified terminal; If terminal is divided into groups, this trigger command is the ID of paged group, and all terminals that belong to this group are all notified objects.This set of terminal ID can be that network side and terminal as offered are good, can be also that terminal is distributed in the time of initial access network.
Do like this to such an extent that advantage is, terminal only need parse Paging message and can know whether and need to start communication process, and signaling consumption is low, and terminal is also without extra operation.
(2) trigger command is arranged in system message
For the new system message of the insensitive service definition of time delay, in this system message, comprise trigger command, i.e. the identify label ID of notified terminal; If a certain group of terminal is to have a group ID, in new system message, carry the ID that wishes paged group.In the new system message producing except whether indicating terminal can communicate by letter, can also necessary other information of carried terminal communication, as for avoid accessing in a large number random turn-on time of the side-play amount etc. of introducing simultaneously.
The mode that terminal reads this system information has following several:
A) terminal is intercepted Paging in set time section, and in Paging, will inform whether terminal needs to read this this system information, and the method that Paging message is informed can be by system information Notification of Changes;
B) read to terminal periodic this system information;
C) for the terminal of the insensitive business of time delay, it defines new Radio Network Temporary Identifier (RadioNetwork Temporary Identifier, be called for short RNTI) (according to the standard of current LTE, its value can be any one between FFF4-FFFC), after terminal detects this RNTI, read this system information.
(3) trigger command is positioned in the Physical Downlink Control Channel information of (Physical Downlink ControlChannel is called for short PDCCH)
Terminal detects after RNTI, to corresponding PDCCH, removes to read trigger command, i.e. the identify label ID of terminal or set of terminal ID also comprises the information such as random turn-on time of side-play amount in PDCCH.

2, UE sends random access leader sequence (RA preamble) to eNB by MSG1 signaling, allows eNB know and exists a terminal to attempt to connect with base station;
3, eNB sends accidental access response message (RA Response) to UE according to the corresponding resource of the leading distribution of confirming by MSG2 signaling, carries time-advance message, the ascending resource of distribution;
4, UE sends RRC connection foundation request (Radio Resource ControlRequest) by MSG3 signaling and, to eNB, in the resource of having distributed, sends the information such as user ID;
5, eNB sends to connect by MSG4 signaling and sets up message (RRC Connection Setup) to UE, carries conflict and solves message;
6, UE sends to connect by MSG5 signaling and is successfully established message (RRC Connection SetupComplete), and wherein portability terminal is to the NAS message of core net;
7 and 8, the authenticated encryption process of core net, eNB sends connection request message (ConnectionRequest) to MME, and MME returns to connect and is successfully established message (Connection Setup) to eNB;
9, eNB is to UE configuration network information (RRC Connection Setup Reconflguration);
10, terminal sends network configuration and completes information (RRC Connection Setup ReconflgurationComplete), and so far, terminal becomes active state by idle state;
11, data communication process (Data transmission);
