SGSN/MME node connects machine type communication interconnected functional blocks MTC-IWF simultaneously.MTC server needs pass through MTC-IWF access carrier network, MTC-IWF have the function of gateway, can shield network internal topology and interface, turn Change the interface protocol between MTC server and network.MTC-IWF function specifically includes that the interfaces such as termination MTCsp, S6m, carries out Interface protocol conversion；Before transmission is established, MTC server is authenticated；To the control plane from MTC server request into Row authorization；Terminal activation request and response message from MTC server are received and dispatched, while can also be transmitted and be activated successfully or fail Report；Optimal terminal is selected to activate transfer mechanism；Generate terminal and activate CDR, and guarantee 3GPP network and MTC server it Between secure communication.

In the present invention, MTC registration and service managing unit (being abbreviated as MTC-RSM) are provided.MTC-RSM is for registering Each MTC application, it can also dispatch MTC device and be linked into network, to slow down the relevant signal load congested conditions of MTC. MTC-RSM can be an independent community or the functional entity of other network units.Fig. 2 citing is shown in HSS/HLR Framework with MTC-RSM module.MTC server can be communicated by MTC-IWF or application layer signaling with MTC-RSM module. It is appreciated that MTC-RSM can be placed on other network nodes such as similar SGSN/MME.

There are three core functions by MTC-RSM: an receives the MTC application registration request come from one or more MTC servers Information；Two, are assisted according to the Advance data quality MTC access parameter provided in registration information, and with the MTC server for representing PLMN network Quotient's MTC access parameter；MTC access parameter is distributed to MTC server in application registration reply message by three,.In another reality It applies in example, these parameters can also be distributed and give PLMN network unit, such as HLR/HSS, SGSN/MME etc..

Fig. 3 is the schematic diagram of registration and access process in the present invention, for being based on provided by the present invention will be described in detail The MTC of MTC-RSM applies turn-on time dispatching method.

MTC server disposes MTC application, including installation and configuration software.MTC server is that access phase is collected in MTC application Information is closed, such as MTC device number, MTC device physical location, preferred communication time interval receives communication time interval, forbids communicating Time interval, frequency data communication, data minus carrying capacity, request access duration, expense budget etc..

Step 1:MTC-RSM receives the MTC application login request message of MTC server transmission.Message includes MTC device Number, MTC device physical location, preferred communication time interval receives communication time interval, forbids communication time interval, and data are logical Believe frequency, data minus carrying capacity, request access duration, expense budget etc..In another embodiment, all parameters are all at one It is transmitted in MTC application login request message.And in another embodiment, all parameters are transmitted in a series of message.

If there is multiple MTC servers, then MTC-RSM can receive the multiple notes sended over from these MTC servers Volume request message.

Step 2:MTC-RSM information according to obtained in login request message calculates optimal MTC device access parameter.Root According to preferred communication time interval, when receiving communication time interval and communication time interval being forbidden to calculate authorization time interval and forbid Between be spaced.Calculating will consider local policy.For example, PLMN should exclude determining time interval from important MTC access.

The communication window of personal MTC device, which calculates, will consider to authorize time interval, disable time interval, frequency data communication, The data payload of each access, access duration etc..Importantly, calculating the existing communication window for being considered as other MTC application.In this way New MTC can be limited and apply the negative effect applied to existing MTC, reach good overall effect.Calculating/optimization can use Operational research tool, such as linear optimization, curve theory, permutation and combination etc..

It should be noted that MTC-RSM can deliberately distribute communication window for personal MTC device.This is and existing skill The randomization of communication window is compared in the authorization time interval that art is mentioned.Communication window energy is deliberately distributed for personal MTC device Enough better ensure that the fair allocat of access window.

When MTC-RSM is that APP calculates communication window, it can make great efforts to adjust MTC access in preferred communication time interval.Such as Fruit first choice communication time interval is difficult to adjust all MTC devices, it will be considered as receiving time interval.In one embodiment In, MTC-RSM negotiates according to receiving time interval and MTC server.In another embodiment, it is used in negotiations process Expense excitation.

MTC-RSM can consider network node capacity when distribution communicates window.For example, SGSN/MME can be proposed clearly at one MTC communication how many resource in the specified period.MTC-RSM should ensure that the MTC communication window newly increased does not violate this limitation. MTC-RSM can collect the capacity data of SGSN/MME or SGSN/MME actively reports capacity parameter to MTC-RSM.

In short, MTC-RSM can consider the capacity limit of other network nodes.

Step 3:MTC-RSM generates registration reply message, sends to MTC server.There is one group of MTC in registration reply message The authorization time interval of equipment and disable time interval, communication window of personal MTC device etc..

In another embodiment, MTC-RSM can provide one or more communication windows for each MTC device.Redundant communication The variable communication window that window is used as MTC device in the first communication window communication failure.Variable communication window usually one-to-one (one The corresponding variable communication window of a MTC device) or N to M (N number of MTC device corresponds to M MTC communication window).

Step 4:MTC-RSM notifies HLR/HSS to update access parameter.The a part of access parameter as MTC user data There are HLR/HSS databases.

Step 5:MTC equipment is combined according to following one of mode or multiple modes updates MTC access parameter:

A) HLR/HSS updates SGSN/MME, then updates MTC device；

B) MTC-RSM updates SGSN/MME, then updates MTC device；

C) MTC server updates MTC device.

It should be noted that allowing the update of dynamic access parameter in the present invention.

The scheduling result that MTC-RSM changes MTC communication window is to better disperse network load and adjust and be newly added MTC application.MTC-RSM calculates new communication window parameter, and updates with HLR/HSS, SGSN/MME and/or MTC device.

Compared with prior art, turn-on time dispatching method provided by the present invention has the characteristics that following:

A) MTC-RSM will consider that existing MTC loads the influence loaded to new MTC；

B) MTC-RSM will find the communication window scheduling of preferred determination for personal MTC device；

C) MTC-RSM will communicate the capacity limit that network node is considered when window scheduling.

In the present invention, existing other MTC application is considered when MTC-RSM module is new MTC application distribution communication window Communicate window.New MTC can be limited in this way and applies the negative effect applied to existing MTC, ensure the smooth fortune of MTC/M2M network Row.

The turn-on time dispatching method provided by the present invention towards MTC application is described in detail above.To this For the those skilled in the art in field, he is done under the premise of without departing substantially from true spirit any obvious Change, the infringement for all weighing composition to the invention patent, will undertake corresponding legal liabilities.
