The embodiment of the invention discloses a kind of control method and device of Stochastic accessing and a kind of accidental access method and device.Below in conjunction with the accompanying drawing in the embodiment of the present invention, the technical scheme in the embodiment of the present invention is clearly and completely described, it is clear that described embodiment is a part of embodiment of the present invention, rather than whole embodiments.Based on the embodiment in the present invention, all other embodiment that those of ordinary skill in the art are obtained on the premise of creative work is not made should all belong to the scope of protection of the invention.
One embodiment of the present of invention provides a kind of control method of Stochastic accessing, as shown in figure 1, including：
S101 :The random access guiding that base station receiving terminal is sent；
S102:The base station sends the accidental access response for indicating the end delay Stochastic accessing.In the present embodiment, base station can send the accidental access response that instruction terminal postpones Stochastic accessing to terminal, send random access guiding if base station is not intended to terminal repeatedly and take substantial amounts of resource, can inform that it postpones Stochastic accessing, so as to save the resource of base station.
An alternative embodiment of the invention provides a kind of accidental access method, as shown in Fig. 2 including： S201 :Terminal sends random access guiding to base station； S202:The terminal indicates the end delay Stochastic accessing from the base station receiving random access response, the accidental access response；
S203:The terminal postpones Stochastic accessing according to the accidental access response.
In the present embodiment, the accidental access response that terminal is sent according to base station postpones Stochastic accessing, advantageously reduces occupancy of the Stochastic accessing to base station resource.
The embodiment of the present invention provides the control method of another Stochastic accessing, as shown in figure 3, including： S301 :The random access guiding that base station receiving terminal is sent；
S302:Base station determines the terminal that the terminal is area covered；
For example, the terminal of area covered refers to the terminal beyond Base Station specifications coverage.Therefore, alternatively, base station judges whether the terminal is the terminal of area covered in this step, if it is, performing step S303;
Alternatively, base station read preamble message in timing alignment (Time Alignment, TA) value, and judge state terminal whether be area covered terminal.For example, when the TA values are more than default thresholding, base station can determine the terminal that the terminal is area covered.
S303:Base station sends the accidental access response for indicating the end delay Stochastic accessing.
The applicable scene of the present embodiment includes：When the terminal that base station is not intended to area covered takes its resource, end delay Stochastic accessing can be informed by accidental access response.
Alternatively, the instruction end delay Stochastic accessing in the present embodiment, including：Indicate that the end delay retransmits random access guiding next time afterwards for a period of time, that is, indicate that the end delay sends the time of random access guiding next time.
In the present embodiment, base station indicates the end delay Stochastic accessing, can there is a variety of implementations, illustrated below.
For example, the accidental access response includes uplink authorization（Uplink Grant, UL Grant), the value of the UL Grant is 0.It should be understood that the citing, which includes accidental access response, includes multiple UL Grant, and each UL Grant value is 0 situation.
Further, accidental access response can include medium access control message head（Media Access Control header, MAC header) and medium education accidental access response（Media Access Control Random Access Response, MAC RAR), shown in ^ mouthfuls of Fig. 4 of MAC RAR, wherein, UL Grant values are used to represent in uplink authorization resource, the present embodiment, and UL Grant values are 0 Illustrate base station not to the terminal distribution ascending resource.Therefore, in the present embodiment, UL Grant values may be used to indicate the end delay Stochastic accessing for 0.
Alternatively, also include temporary cell Radio Network Temporary Identifier (Temporary cell radio network temporary identifier in the accidental access response, Temporary C-RNTI), and the value of the Temporary C-RNTI indicates that the terminal enables default time delay.Further, Temporary C-RNTI value can be OxFFFC, to indicate that the terminal enables default time delay.Alternatively, default time delay is 60000 milliseconds.It should be noted that, the value of the Temporary C-RNTI can be considered as to the terminal needs the index of time of delay, namely the value of the Temporary C-RNTI indicates that the terminal needs the time postponed, this is the equal of that the situation for being OxFFFC by the value of the Temporary C-RNTI is directly considered as to the terminal and indicates that default time delay is certain special time, such as 60000 milliseconds.
And for example, the payload corresponding with the mark of the random access guiding in the accidental access response is sky, it can also be used to indicate the end delay Stochastic accessing.Alternatively, as shown in Figure 5, the accidental access response can include medium access control message head MAC header and medium education accidental access response MAC RAR, last subheader subheader in the MAC header includes the mark of the random access guiding, and MAC RAR corresponding with last described subheader is sky.For example, having 6 subheaders in MAC header, the mark of the random access guiding of 6 terminals is carried respectively, the mark of the random access guiding of the terminal is carried in last subheader, and 5 MAC RAR are only included in accidental access response.
Method described in the present embodiment, base station postpones terminal by the accidental access response sent to terminal and sends the time of random access guiding next time, so as to reduce the quantity of the random access guiding of receiving terminal, saves the resource of base station.
The embodiment of the present invention provides another accidental access method, as shown in fig. 6, including：
S601 :Terminal sends random access guiding to base station；
S602:The terminal indicates the end delay Stochastic accessing from the base station receiving random access response, the accidental access response；
S603：Before judging that the terminal receives the accidental access response from the base station, whether the number of times that the terminal sends random access guiding to the base station is more than preset times, if it is, S604 is performed, if not, performing S601; In the present embodiment, the purpose for setting the number of times limitation for sending random access guiding is, if the terminal of a non-area covered is because of the terminal with area covered in (the Time Transmission Interval of transmission intercal at the same time, TTI identical random access guiding is sent on), and ^ stations are mistakenly considered the terminal that it is area covered, the terminal of this non-area covered still can proceed Stochastic accessing, and Stochastic accessing is postponed without the erroneous judgement because of base station.That is, after the above-mentioned judgement on sending the number of times of random access guiding of increase, it can avoid postponing the terminal in method " accidental injury " described base station normal coverage areas of Stochastic accessing, namely avoid result in that terminal in the base station normal coverage areas is inappropriate to be delayed by random access procedure.
In the present embodiment, using preset times as 1 citing.After S603, if S601 is jumped to, and order is performed to S603, then the number of times that now terminal adds up to send random access guiding to the base station is 2, then jumps to S604.
S604:The terminal postpones Stochastic accessing according to the accidental access response.
According to the difference of the accidental access response received, the process of the end delay Stochastic accessing may be different, illustrated below.
For example, the accidental access response includes UL Grant, when the value of the UL Grant is 0, the terminal determines that the accidental access response indicates the end delay Stochastic accessing, and after postponing the time delay that one section of default time delay or terminal are known by other means, the random access guiding is sent to the base station.
Alternatively, the accidental access response also includes Temporary C-RNTI, the value of the Temporary C-RNTI（Such as OxFFFC) indicate that the terminal enables default time delay（Such as 60000 milliseconds）When, then the terminal is receiving the accidental access response from the base station, and postpones after the default time delay, and the random access guiding is sent to the base station.
And for example, payload corresponding with the mark of the random access guiding in the accidental access response is sky, further, the accidental access response includes MAC header and MAC RAR, last subheader in the MAC header includes the mark of the random access guiding, MAC RAR corresponding with last described subheader is space-time, the terminal is receiving the accidental access response from the base station, and postpone after preset time, send the random access guiding to the base station.The preset time can be 60000 milliseconds.
In the present embodiment, judge terminal whether postpone to send random leading condition for " terminal to Whether the number of times that the base station sends random access guiding is more than preset times "; in addition; judge whether terminal postpones to send random leading condition can also be " whether the number of times that the terminal sends random access guiding to the base station is not less than preset times "; if before i.e. described terminal receives the accidental access response from the base station; the number of times that the terminal sends random access guiding to the base station is not less than preset times; then the terminal postpones Stochastic accessing according to the accidental access response；Or, if the terminal is received from the base station before the accidental access response, the number of times that the terminal sends random access guiding to the base station is less than preset times, then the terminal sends the random access guiding to the base station, until when the number of times that the terminal sends the random access guiding to the base station is not less than preset times, the terminal postpones Stochastic accessing according to the accidental access response message.
It is similar with the flow shown in Fig. 6 based on the random access procedure of above-mentioned Rule of judgment " whether the number of times that the terminal sends random access guiding to the base station is not less than preset times ", including：Terminal sends random access guiding to base station；
The terminal indicates the end delay Stochastic accessing from the base station receiving random access response, the accidental access response；
Before judging that the terminal receives the accidental access response from the base station, whether the number of times that the terminal sends random access guiding to the base station is not less than preset times, if, the terminal is according to the accidental access response, postpone Stochastic accessing, the process for postponing Stochastic accessing can be as described in S604, if it is not, then the terminal sends the random access guiding to the base station.
