Below in conjunction with accompanying drawing, the method for the invention is described in further detail.It should be noted that, when not conflicting, the embodiment in the application and the feature in embodiment can combine mutually.Below with reference to the accompanying drawings and describe the present invention in detail in conjunction with the embodiments.
Basic thought of the present invention is, internet of things equipment is divided into groups, each grouping arranges a time of delay, during internet of things equipment access, send ranging code to after control station, from the control station receive delay time, after arriving time of delay, again send ranging code to control station, thus avoid different internet of things equipment to collide.
As shown in Figure 4, the invention provides following scheme:
Scheme one:
During the direct access control station of internet of things equipment, application according to the present invention comprises in the method for network access of the wireless communication system of Internet of Things:
Equipment is divided into groups, sends grouping information to equipment.Grouping can be divide into groups according to device distribution position, functions of the equipments, device category, equipment networking priority etc.Grouping information can be sent to equipment by control station.
Control station can send above-mentioned grouping information by one of following: system configuration message, superframe header.
Further, described grouping information comprises: group character and/or ranging information corresponding to grouping, the ranging information of described grouping correspondence comprise following one of at least: the range frequency information that ranging time information corresponding to ranging code collection information corresponding to grouping, grouping, grouping are corresponding.
Equipment sends ranging code to control station on the ranging region of ranging time and range frequency composition, and control station returns ranging response message to described equipment.This step has two kinds of implementations:
Mode one:
Described equipment sends described ranging code to control station at the ranging region of ranging time and range frequency composition.Described equipment carries group character while the described ranging code of transmission, is used to indicate the grouping that this equipment needs to add.Wherein, equipment can according to the application of self, or system is pre-configured etc. knows the grouping oneself needing to add.
Control station sends ranging response message to described equipment after successfully detecting the ranging code that described equipment sends, wherein comprise following one of at least: the code word that success is resolved, the time adjusted value of described equipment, frequency adjusted value, power adjustment, distance measuring states value.Described distance measuring states value is one of following: exit, continue and success.Control station also carries packetization delay temporal information in the ranging response message sending to described equipment, the time of delay of the grouping correspondence that packetization delay temporal information indicates described equipment to add, wherein, the time of delay of different grouping correspondences is entirely not identical, usually, the time of delay that different groupings is corresponding different.Wherein, the grouping that the group character determination equipment that control station sends according to equipment adds, thus the time of delay returning this grouping correspondence is to this equipment.
Mode two
Described equipment sends described ranging code to control station at the ranging region of ranging time and range frequency composition.When described grouping information comprises the ranging information of grouping correspondence, described equipment is before the described ranging code of transmission, from the ranging information of this grouping correspondence, ranging information is selected according to self needing the grouping added, this ranging information comprise in ranging code, ranging time, range frequency one or more, then find range according to the ranging information selected.Wherein, equipment can according to the application of self, or system is pre-configured etc. knows the grouping oneself needing to add.
Control station sends ranging response message to described equipment after successfully detecting the ranging code that described equipment sends, wherein comprise following one of at least: the code word that success is resolved, the time adjusted value of described equipment, frequency adjusted value, power adjustment, distance measuring states value.Described distance measuring states value is one of following: exit, continue and success.Control station also carries packetization delay temporal information in the ranging response message sending to described equipment, the time of delay of the grouping correspondence that packetization delay temporal information indicates described equipment to add, wherein, the time of delay of different grouping correspondences is entirely not identical, usually, the time of delay that different groupings is corresponding different.Wherein, control station determines according to the ranging code received and/or the grouping that receives the ranging region of described ranging code corresponding the grouping that described equipment adds, thus the time of delay returning this grouping correspondence is to this equipment.
Further, after described equipment receives ranging response message, if described distance measuring states value is for continuing, and comprise adjusted value in ranging response message, then perform relevant adjustment according to adjusted value, and timing from receiving this ranging response message, again send ranging code when time of delay arrives.
Further, said process continues to carry out, until the distance measuring states that control station sends is successfully, in the process, described equipment can continue to use time of delay, also can not use.
Further, distance measuring states value is successfully, control station is that described equipment distributes the bandwidth sending distance measurement request message, control station receives the distance measurement request message of described equipment, send ranging response message, for described equipment allocation identification information, initial ranging completes, and described equipment continues to perform follow-up access process.
In above-mentioned method for network access, owing to being provided with the different packetization delay time, the internet of things equipment adding different grouping carry out finding range time of adjustment is just different, makes multiple equipment adding different grouping stagger in time like this, reaches the object reducing collision.
In addition, when ranging code collection, ranging time, range frequency are divided according to grouping, the code collection of the equipment adding different grouping can select oneself needs to add grouping correspondence when accessing, time or frequency, and corresponding ranging code is sent on corresponding ranging region, the probability that such control station receives same code word on same time-frequency reduces, thus decreases collision.
