Description
Technical field
The present invention relates to moving communicating field, be meant a kind of business access method, system and terminal especially.
Background technology
Present mobile communications network; For example: global mobile communication (Global system for Mobile Communication; GSM), UMTS (Universal Mobile Telecommunications System; UMTS), (Time Division-Synchronous Code Division Multiple Access TD-SCDMA) is mainly human hand-held portable terminal communication service is provided in the TD SDMA access.
In recent years, along with the rise that Internet of Things is used, cellular mobile communication networks also begins for the built-in terminal that is installed on the various objects communication service to be provided gradually.It has broken through the space-time restriction and the region obstacle of traditional communication mode, makes the enterprise and the public break away from the cable constraint, lets the client more effectively control cost, reduce mounting cost and easy to use.In addition; Growing demand is promoting the Internet of Things application and is constantly advancing; Constantly increase with information processing capability and the network bandwidth and conflictingly to be, the means that information is obtained lag far behind, and Internet of Things is used this demand that has well satisfied people; Can monitor external environment condition in real time through its people, realize on a large scale, the information gathering of automation.Therefore, Internet of Things can be widely used in sector application, domestic. applications, individual's application etc.Be installed in radio frequency identification (the Radio Frequency Identification on the various objects; RFID), information sensing equipment such as infrared inductor, global positioning system, laser scanner; Be connected with information centre through cellular mobile communication networks; Carry out information exchange and communicate by letter, to realize intellectuality identification, location, tracking, monitoring and management object.Sector application is like traffic monitoring, warning system, rescue at sea, automatic vending machine, driving paying etc.Domestic. applications is like automatic data logging, temperature control etc.The individual use as: life detection, far-end diagnosis etc.
But if service access is carried out at synchronization in the terminal, it is congested communication system to occur.
In traditional access request strategy, after the access request of its application layer is received at the terminal, send the request of access to network immediately; Do not insert the request response if receive at the terminal in a period of time, can retransmit the request of access so, do not insert the request response in ensuing a period of time if still receive at the terminal; So also can retransmit the request of access; Maximum number of retransmissions is Max-retrans time, and what retransmit the request of access is to obey [S, S+T] evenly random number of probability density distribution at interval.Max-retrans, S, the T parameter is given the terminal by network side through the message prior notice.
But traditional scheme can't solve great amount of terminals and send the congestion problems that the request of access causes in the short time simultaneously.Existing 1 the core concept of improving one's methods is exactly after the access request of its application layer is received at the terminal, do not send the request of access to network side immediately, but random delay a period of time is obeyed the even distribution of 0～Max-Delay this time of delay.Can solve the congestion problems when first access is asked like this, Max-Delay gives the terminal by network side through the message prior notice.
But existing 1 the shortcoming of improving one's methods is; Though initiate simultaneously to access terminal what; Its average terminal is only relevant with Max-Delay turn-on time, and is little if Max-Delay is provided with, and can not guarantee the success rate that the terminal is inserted; If be provided with greatly, can not guarantee terminal average turn-on time again.
Existing 2 the core concept of improving one's methods is: first strategy that inserts request still adopts conventional method; And interval that retransmit to insert request be not in the conventional method each retransmission delay time all obey identical even distribution, use different probability density functions and generate time of delay but different repeating transmission inserts the request sequence number.Give an example: be the uniform probability density function of [S, S+Tn] each time of delay of retransmitting the request of access, and Tn is the maximum delay window size that the n time repeating transmission inserts request.
Existing improving one's methods 1 and 2 can solve the collision problem of business burst access.But its parameter configuration is very difficult, because of not knowing the number of terminals that burst inserts is what in network and terminal, so the window of generation random delay is little, just can not guarantee terminal access success rate; Window is big, can prolong turn-on time again.Therefore, when parameter configuration and burst insert request quantity and do not match, when perhaps burst inserts request quantity and exceeds the disposal ability of above-mentioned solution, still possibly insert congestedly, so just can not guarantee that the access request of important service is in time handled.
