Embodiment bis-
Group's terminal access method that the embodiment of the present invention two provides, take group's terminal as ammeter, and to base station, sending electric quantity data is that example describes.As shown in Figure 2, the method step comprises:
Terminal in S201, group, in entering network process or after networking, is obtained the parameter relevant to group from the base station of network side, at least comprises: terminal number m, the call number index of this terminal in group that group is current; Wherein, the terminal in group is corresponding one by one with call number index, and call number index is unique in group.
For example: in the present embodiment, suppose the call number index continuous programming code of each terminal in group, and since 0 continuous programming code.Such as there being m terminal, the call number index of each terminal is respectively 0 to m-1.When the group of BTS management changes, network side may be given each terminal distribution m value and index value again, and broadcast to terminal.
In addition, the parameter relevant to group can also comprise: the group sign of this group.Whether the message that terminal can judge base station transmission according to this group sign is for this terminal place group.
S202, base station are to terminal broadcast access opportunity information.
In this access opportunity information, can comprise such as base station and can provide the information such as how many access chances in 1 frame or subframe.
The set of terminal of S203, base station Xiang Yige group is sowed and is sent out task message, carries this group and organize accordingly sign in this task message, in this task message, except comprising the concrete behavior of needs execution, also comprises and stipulates that this task accesses time span used.
Such as: this task message, can carry out and network or position is upgraded or data receiver or data such as report at the task for notification terminal, such as the traffic indication message under beep-page message, park mode etc.
At this, suppose that the time span that this task completes is Tt, further, can there is retention time Tr in the rear portion of this Tt, or the forefront of this Tt can exist Ta turn-on time.So, " accessing time span used " herein can be Tt, can be also Tt-Tr, or Ta.
Terminal in S204, group according to access opportunity information, access the call number index of time span used, terminal number m and this terminal, obtain the access chance of this terminal.
Take access time span that time span used completes as this task as Tt be example, concrete account form can be one of following two kinds:
Mode one: the time span Tt that terminal completes according to access opportunity information, task, obtains the access chance sum N in time period Tt.The access chance of the terminal that call number is index is (1+index * [N/m]) or (1+[index * N/m]) individual access chance in time period Tt.At this, [] represents to round, and the mode of rounding can need to specifically be set as rounding up or rounding downwards according to actual environment.In addition, in actual application, if selected, a kind ofly round position and round after mode, all terminals in Ze Gai group all should be deferred to this account form, can not arbitrarily change.
For example, there are 5 terminals, i.e. m=5 in certain group; The call number of terminal is from 0 to 4.Suppose that access chance adds up to 6, i.e. N=6, the mode that rounds is for rounding downwards.As shown in Figure 3, the access of this each terminal of group is sequentially:
Terminal A (call number 0): access chance is (1+index * [N/m])=(1+0 * [6/5])=1 the access chance in time period Tt;
Terminal B (call number 1): access chance is (1+index * [N/m])=(1+1 * [6/5])=2 the access chances in time period Tt;
Terminal C (call number 2): access chance is (1+index * [N/m])=(1+2 * [6/5])=3 the access chances in time period Tt;
Terminal D (call number 3): access chance is (1+index * [N/m])=(1+3 * [6/5])=4 the access chances in time period Tt;
Terminal E (call number 4): access chance is (1+index * [N/m])=(1+4 * [6/5])=5 the access chances in time period Tt.
By above-mentioned result of calculation and Fig. 3, can be found out, after each terminal is calculated, can realize even access at the appointed time, the possibility having clashed while having reduced each terminal access.
Mode two: the time span Tt that terminal completes according to access opportunity information, task, obtains total frame or number of sub frames Nt in time period Tt.Here Nt and Tt distinguish in unit, and when DangTt unit is frame or subframe, both numerical value is the same, without conversion.
The initial time of the time span Tt that if T0 is task to be completed, be (T0+index * [Nt/m]) or (T0+[index * Nt/m]) turn-on time of the terminal that call number is index.At this, [] represents to round, and the mode of rounding can need to specifically be set as rounding up or rounding downwards according to actual environment.In addition, in actual application, if selected, a kind ofly round position and round after mode, all terminals in Ze Gai group all should be deferred to this account form, can not arbitrarily change.
After terminal calculates above-mentioned turn-on time, on the frame or subframe of this turn-on time, or select an access chance from random in the frame of this turn-on time or the nearest frame that carries access chance of subframe or subframe, as the access chance of this terminal.This is because access chance not necessarily has in every frame or subframe.
S205, terminal are initiated access process in the access chance of this terminal obtaining.
Take (T0+index * [Nt/m]) be example, supposing has m terminal in group, the call number of each terminal is from 0 volume to m-1, each terminal in task time period Tt turn-on time distribution schematic diagram as shown in Figure 4.In Fig. 4, terminal 0 is initiated access constantly at T0, and terminal 1 is at T0+[Nt/m] index that constantly initiates to access terminal initiates access at T0+index * [Nt/m] m-1 that constantly initiates to access terminal constantly at T0+ (m-1) * [Nt/m].
By above-mentioned result of calculation and Fig. 4, can be found out, after each terminal is calculated, can realize even access at the appointed time, the possibility having clashed while having reduced each terminal access.
Each terminal in group all carries out respectively, after the process of above-mentioned steps S201～S205, having realized the access of group's terminal.
Group's terminal access method that the embodiment of the present invention two provides, terminal in group is obtained the parameter relevant to group (terminal number m, the call number index of this terminal in group that group is current) from base station, receive the access opportunity information of base station broadcast, the task message that contains the time span Tt that task completes that receives that base station sends; Afterwards, time span Tt, the terminal number m that group's terminal completes according to access opportunity information, task and the call number index of this terminal, obtain the access chance of this terminal; And initiate access process in this access chance.Like this, the time span Tt that each terminal in group can complete according to the relevant parameter of current group, access opportunity information, task etc. calculates the concrete access chance of self initiating access process, make each terminal in group to carry out equably at the appointed time access operation, the possibility having clashed while having reduced each terminal access.
In addition, in the present embodiment, in the task message that base station sends to terminal, can also comprise terminal appointed information, being this task specifies separately a part of terminal to operate, only have this part terminal to receive after task message, can carry out the access computational methods that the present embodiment provides, other-end, due to without carrying out task operating, does not therefore access calculating.

The initial time of the time span Tt that if T0 is task to be completed, like this, Tt is divided into two sections: the last period is (Tt-Tr) from T0 to T0+; Rear one section from T0+ (Tt-Tr) to T0+Tt.The initial access of terminal can only be carried out on the last period, so the time of terminal access is that T0 is to T0+ (Tt-Tr).
Similar with step S201～S205 of embodiment bis-, in the present embodiment, the call number index that supposes each terminal in group is continuous programming code also, and is since 0 continuous programming code.If any m terminal, the call number index of each terminal is respectively 0 to m-1.The access chance of terminal is calculated the two kinds of modes that also comprise:
Mode one: time span Tt, retention time Tr that terminal completes according to access opportunity information, task, obtain the access chance sum N ' in time period Tt-Tr.The access chance of the terminal that call number is index is (1+index * [N '/m]) in time period Tt-Tr or (1+[index * N '/m]) individual access chance.At this, [] represents to round, and the mode of rounding can need to specifically be set as rounding up or rounding downwards according to actual environment.In addition, in actual application, if selected, a kind ofly round position and round after mode, all terminals in Ze Gai group all should be deferred to this account form, can not arbitrarily change.
Mode two: the time span Tt that terminal completes according to access opportunity information, task, obtains total frame or number of sub frames Nt in time period Tt.Terminal, according to access opportunity information, retention time Tr, obtains total frame or number of sub frames Nr in time period Tr.Like this, the time of terminal access be T0 to T0+ (Tt-Tr), corresponding (Nt-Nr) individual frame.
Equally, Nt, Nr and Tt, Tr distinguish in unit, and when Tt, Tr unit are frame or subframe, both numerical value is the same, without conversion.
Call number is that be (T0+index * [(Nt-Nr)/m]) or (T0+[index * (Nt-Nr)/m]) turn-on time of the terminal of index.At this, [] represents to round, and the mode of rounding can need to specifically be set as rounding up or rounding downwards according to actual environment.In addition, in actual application, if selected, a kind ofly round position and round after mode, all terminals in Ze Gai group all should be deferred to this account form, can not arbitrarily change.
After terminal calculates above-mentioned turn-on time, on the frame or subframe of this turn-on time, or select an access chance from random in the frame of this turn-on time or the nearest frame that carries access chance of subframe or subframe, as the access chance of this terminal.This is because access chance not necessarily has in every frame or subframe.
Take (T0+index * [(Nt-Nr)/m]) be example, supposing has m terminal in group, the call number index of each terminal is from 0 volume to m-1, mode two each terminals in task time period Tt-Tr turn-on time distribution schematic diagram as shown in Figure 5.In Fig. 5, terminal 0 is initiated access constantly at T0, and terminal 1 is at T0+[(Nt-Nr)/m] index that constantly initiates to access terminal initiates access at T0+index * [(Nt-Nr)/m] m-1 that constantly initiates to access terminal constantly at T0+ (m-1) * [(Nt-Nr)/m].
By above-mentioned result of calculation and Fig. 5, can be found out, after each terminal is calculated, can realize even access at the appointed time, the possibility having clashed while having reduced each terminal access.
