The embodiment of the present invention provides a kind of method for sending information, as shown in figure 1, the executive agent of this method sets for network Standby, this method includes：

S101, the network equipment to terminal send command information when, however, it is determined that the terminal be in non-sleep state, the network Equipment sends the command information to the terminal.

S102, however, it is determined that in a dormant state, the network equipment sends first message to the terminal to mapped device, so as to this Mapped device stores the first message, and after the terminal departs from resting state, the mapped device receives terminal transmission Second message, and sent the first message to the terminal according to second message, to cause the terminal according to the first message The 3rd message is sent to the network equipment and obtains the command information.

Especially, no matter the network equipment sends how many command informations to the terminal, only sends a first message to reflecting Jet device, to point out mapped device to there is command information to send to terminal.

Specifically, the 3rd flag bit is set to send mark by the network equipment after first message is sent to mapped device Know；This sent mark indicate the network equipment sent the first message；And receive the of terminal transmission in the network equipment After three message, the 3rd flag bit is set to not send mark；So, the network equipment is it is determined that the 3rd flag bit is not send During mark, first message is sent to mapped device, for example, the network equipment to the terminal when sending command information first time, really The fixed flag bit is does not send mark, and the network equipment sends first message to mapped device, and after first message is sent, network is set Standby to be set to the 3rd flag bit to have sent mark, so, the network equipment to terminal when subsequently sending command information, however, it is determined that 3rd flag bit is has sent mark, and expression has been transmitted across the first message, then first message need not have been retransmited, so as to subtract The expense of small signaling.

In addition, mapped device may be stored with, multiple different network equipments are sent to the first information of the terminal, therefore, Preferably, when the terminal departs from resting state, the mapped device is received after the second message of terminal transmission, and mapped device will Send and be integrated into a prompting message to the corresponding first message of command information of same terminal and send to the terminal, the prompting Message includes sending command information to the address of the network equipment of the terminal.

Further, it is determined that the terminal in a dormant state before, the network equipment receive the terminal transmission the 4th message, After the 4th message is received, the first flag bit is set to dormancy identification.

Wherein, the dormancy identification indicates the terminal in a dormant state.

Determine that the terminal can include in a dormant state：The network equipment determines that first flag bit is dormancy identification.

Further, the network equipment receives the 3rd message of terminal transmission；

After the 3rd message is received, first flag bit is set to non-sleep and identified by the network equipment, wherein, this is non- Dormancy identification indicates the terminal and is in non-sleep state；

Then determine that the terminal includes in non-sleep state：Determine that first flag bit identifies for non-sleep.

Specifically, terminal departs from after resting state, and the second message is sent to the network equipment, the network equipment receive this After two message, to terminal send first message, with inform the terminal send command information the network equipment mark, terminal according to The mark of the network equipment sends the 3rd message to the corresponding network equipment, and the network equipment disappears in receive terminal transmission the 3rd After breath, the command information is sent to terminal, so that terminal gets the command information, meanwhile, the network equipment can by this first Flag bit resets to non-sleep mark, to determine that the terminal is in non-sleep state, now, order is subsequently sent in the network equipment During information, when it is determined that first flag bit is non-sleep mark, directly the command information can be sent to terminal, so as to carry The high efficiency of data transfer.

Further, the network equipment receives the corresponding end points of the terminal (End Point) mark of terminal transmission and reflected The address of jet device, wherein, the address of the corresponding Endpoint ID of the terminal and mapped device may be embodied in above-mentioned 4th message In.

Wherein, the Endpoint ID for it is corresponding with end points mark, the end points distributed by the mapped device and with the terminal-pair Should, the end points is used for the message that storage networking device is sent.The network equipment is set according to the corresponding Endpoint ID of the terminal and mapping Binding relationship between the standby address configuration network equipment, the terminal and the mapped device, so, the network equipment subsequently to When mapped device sends first message, directly first message can be sent to the mapped device according to the binding relationship, be not required to The information such as the address of the corresponding Endpoint ID of terminal and mapped device are searched again, are reduced the time delay of message transmission, are improved Efficiency of transmission.It should be noted that the Endpoint ID included when the 4th subsequently received message and the address of mapped device When the address of corresponding from above-mentioned binding relationship Endpoint ID and mapped device is different, the network equipment needs to re-establish new tie up Determine relation, i.e., new binding pass is set up in the Endpoint ID included according to the 4th message of receipt of subsequent and the address of mapped device System.

Further, when terminal is prepared to enter into resting state, if mapped device distribution end points failure (such as mapped device Space for distributing end points is inadequate), then do not include Endpoint ID, now, the network equipment in the response message sent to terminal Also the address of Endpoint ID and mapped device is not included in the 4th message received, therefore, this method also includes：The network equipment exists When determining the terminal in a dormant state, the command information is stored.

When the terminal departs from resting state, the network equipment receives the 5th message of terminal transmission, and is receiving this After 5th message, the command information is sent to the terminal.

Specifically, however, it is determined that end points distribution failure, then when terminal departs from resting state, terminal is sent out to the network equipment Send the 5th message, and receive the command information that the network equipment is sent according to the 5th message, specifically, the network equipment it is determined that The terminal in a dormant state when, store the command information sent to terminal, the terminal depart from resting state when, set to network Preparation send the 5th message, and the network equipment sends command information to terminal after the 5th message is received.

It should be noted that above-mentioned first message can be prompting message, for pointing out the mapped device network equipment There is command information to send to terminal, above-mentioned second message can be to obtain request message, for departing from dormancy in the terminal During state, terminal obtains the first message of storage to mapped device, and above-mentioned 3rd message can be data acquisition message, for end End obtains command information from the network equipment, and the 4th message can be dormancy notification message, for the terminal notification network equipment In a dormant state, the 5th message can be data acquisition message to the terminal, and order letter is obtained from the network equipment for terminal Breath.

The embodiment of the present invention provides a kind of method for sending information, as shown in Fig. 2 the executive agent of this method is terminal, This method includes：

S201, terminal send the 4th message and enter resting state, so that the network equipment is after the 4th message is received, The terminal is determined in a dormant state according to the 4th message, and when the network equipment sends command information to the terminal, to Mapped device sends first message, so that the mapped device stores the first message.

Further, when the network equipment determines that the terminal is in non-sleep state, terminal receives network equipment hair The command information sent.

Alternatively, terminal sends the 4th message and can realized by following three kinds of modes：

Mode one：The message of terminal broadcast the 4th.

Mode two：The message of terminal multicast the 4th.

Mode three：Terminal sends the 4th message to the network equipment.

It should be noted that in mode three, terminal sends the 4th to each network equipment corresponding with the terminal Message, it is therefore desirable to substantial amounts of Signalling exchange, so that the expense of signaling is added, it is therefore preferable that employing mode one or mode two In method send the 4th message.

Further, before the terminal sends the 4th message and enters resting state, the terminal is sent to mapped device reflects Request message is penetrated, so that the mapped device distributes the terminal corresponding end points according to the mapping request message, the end points is to that should have Endpoint ID, the end points is used for the message that storage networking device is sent.

Terminal receives the Endpoint ID of mapped device transmission and stores the Endpoint ID.

Wherein, the Endpoint ID for it is corresponding with end points mark, the end points distributed by the mapped device and with the terminal-pair Should.

Receiving Endpoint ID that the mapped device sends and after storing the Endpoint ID, the second flag bit is set to the One mark；Terminal sends the 4th message according to first mark；Wherein, the 4th message includes：The Endpoint ID and the mapping The address of equipment.

After the terminal sends the 4th message according to first mark, the second flag bit is set to the second mark by terminal.

Further, when second flag bit is the second mark, the terminal sends the 4th message according to the second mark；Its In, the 4th message does not include the Endpoint ID and the address of the mapped device.

Specifically, when the second flag bit is set to the first mark (such as second flag bit being set into 1), terminal root The 4th message is sent according to first mark, the network equipment is after the 4th message is received, according to the end points in the 4th message Binding relationship between mark and the address configuration of the mapped device network equipment, the terminal and the mapped device, in the second mark When will position is set to the second mark, terminal sends the 4th message according to second mark, now, due to not wrapped in the 4th message The address of Endpoint ID and mapped device is included, therefore, the network equipment carries out the transmission of signaling according to existing binding relationship.This Sample, for identical Endpoint ID, due to the existing binding relationship of the network equipment, therefore terminal need not be according to the second mark The Endpoint ID is carried in the 4th message sent, so as to save the expense of signaling.

If it is to be prepared to enter into resting state (such as terminal in terminal that above-mentioned terminal sends mapping request message to mapped device Do not carry out data interaction) when carry out, however, it is determined that end points distribution failure, then when terminal departs from resting state, terminal to The network equipment sends the 5th message, and receives the command information that the network equipment is sent according to the 5th message, specifically, net Network equipment it is determined that the terminal in a dormant state when, store the command information sent to terminal, the terminal depart from dormancy shape During state, the 5th message is sent to the network equipment, the network equipment sends command information to end after the 5th message is received End.

S202, the terminal depart from resting state after, terminal to mapped device send the second message, so as to the mapped device After second message is received, the first message is sent to the terminal.

Mapped device empties what is stored in the corresponding end points of the Endpoint ID after the first message is sent to the terminal Message.

Further, if it is that will enter resting state in terminal that above-mentioned terminal sends mapping request message to mapped device Shi Jinhang's, and end points is allocated successfully, then when terminal departs from resting state, terminal is sent to the mapped device deletes mapping and disappears Breath, so that the mapped device discharges the corresponding end points of the Endpoint ID according to the deletion mapping message.

S203, terminal receive the first message of mapped device transmission, and are sent out according to the first message to the network equipment Send the 3rd message and obtain the command information.
