Brief description of the drawings
Fig. 1 is the flow chart of large period paging method in the application；
Fig. 2 is the schematic diagram that the large period original position of different beep-page messages is set.
Embodiment
In order that the purpose of the application, technological means and advantage are more clearly understood, the application is done below in conjunction with accompanying drawing
It is further described.
In existing large period paging method, large period immobilizes all the time, therefore, fewer in activation group number
In the case of, hysteresis access delay is reduced, and in the case where activation group is more, volume of business is influenceed and compared by beep-page message
It is relatively limited, particularly under the conditions of small bandwidth.The problem of based in above-mentioned existing large period paging method, the basic think of of the application
Want to be：Adaptive according to group number size progress group paging large period, in activation group, fewer scene shortens paging
The large period that message is sent, so as to reduce paging time delay；In the more scene of activation group, increase the big of beep-page message transmission
In the cycle, so as to reduce the occupancy of paging channel resource, improve the volume of business of system.
Fig. 1 is the flow chart of large period paging method in the application.As shown in figure 1, this method includes：
Step 101, after activation group number in systems changes, according to having activated group number and single GPCCH
The ratio for the maximum paging group number that PCH is supported, it is determined that having activated the large period of group.
The group's foundation sent from core net, group's release, group's contextual modifications are received in NodeB（Increase or delete
Subtract group）, indicated according to these message, update the group number of activation.When the group number of activation changes, count again
Calculate the current large period for having activated group.
The maximum ratio for paging group number that can be specifically supported according to group number has been activated with single GPCCH PCHs
Value, it is determined that having activated the large period of group.For example, it can calculate as follows：The large period of group is activated
GpcchPerAjustVal=Ceil (maximum paging groups that the group number activated/single GPCCH PCHs are supported
Number) * large period adjusting steps.
Wherein, the large period value for having activated group is in units of the duration for paging the minor cycle, that is to say, that the calculating
The large period value of group that what is gone out activated is the duration of large period relative to the multiple of minor cycle duration.Large period adjusting step is
Page the minimum multiple of large period relative paging minor cycle；The maximum paging group number that single GPCCH PCHs are supported can be with
Determine as follows：Code check can be preset according to GPCCH（Such as 0.117）The information bit of next group paging,
Determine the number of resources shared by a group paging（According to resource block RB numbers=1.7RB in LTE system）, it is further according to used
System amount of bandwidth determines the group paging number that can be carried in a PCH.For example, in single beep-page message 0.117
Code check under, in the case where GPCCH uses QPSK adjustment modes, group paging is about 48bit, such a group paging
Shared resource block is 1.7 RB, and the group paging number carried in the system of different bandwidth is as shown in table 1, wherein, in 5M
There are 25 RB in system, can about carry 16 group pagings.
Table 1
, can be to large period for the transmission resource of the public message for carrying out large period transmission and saving system infrequently
Adaptive adjusted value carries out lower limit protection so that the large period finally used is not less than default large period minimum value
GpcchPerAjustValMin.That is, the large period value finally determined can be further limited to GpcchPerAjustVal
=max { GpcchPerAjustValMin, Ceil (the maximum paging group number that the group number of activation/single PCH is supported) *
GpcchPerAjustValMin};Wherein, GpcchPerAjustValMin is the minimum of paging large period relative paging minor cycle
Multiple, the minimum multiple conduct can configure determination based on experience value with parameter, in this case, large period adjusting step=
GpcchPerAjustValMin；
, can be adaptive to large period in order to further limit the delay that the excessive user brought of large period accesses group and brought
Adjusted value is answered to carry out upscale protection so that the large period finally used is no more than default large period maximum
GpcchPerAjustValMax, that is to say, that the large period value finally determined can be further limited to
GpcchPerAjustVal=min { GpcchPerAjustValMax, Ceil (group numbers of activation/single paging letter
The maximum paging group number that road is supported) * GpcchPerAjustValMin }.Wherein, GpcchPerAjustValMax is big for paging
Cycle phase to page the minor cycle maximum multiple, the maximum multiple also by empirical value come configure determine.
Step 102, for the activation group into large period, according to the hair of current large period progress beep-page message
Send.
When carrying out the transmission of beep-page message according to large period, it should so that all group page messages are equably in big week
Be transmitted in phase, as far as possible cause each group page message be equably on Cycle Length, that is to say, that for it is each
Group is activated, respective beep-page message is uniformly sent in same time period.Such as the large period of paging is group paging Xiao Zhou
8 times of phase, the large period of each group paging is 8, but the original position that the biasing paged is paged in other words is different, such as
Shown in Fig. 2.
Specifically, the mode of respective beep-page message is uniformly sent in same time period to be carried out as follows：
A counter T is set for all groups are unified, after minor cycle time-out, counter adds 1, i.e. T=T+1;
After having any group to enter large period, the startup offset that the group sends beep-page message according to large period is
The current large period durations of Offset=T mod；Wherein, mod represents modulo operation.
Because group paging enters large period than more random, the startup offset of such group can be uniform at random on large period
It is distributed between large period.
After the group number of activation changes, current large period is calculated, if large period value changes, the large period
It may become big or diminish.At this moment, it is preferable that corresponding group can be updated to each activation group for having been enter into large period
Group paging bias.
The mode of specific renewal group paging bias can have the following two kinds：
Mode one, however, it is determined that the large period duration gone out shortens, then by the startup offset of each group for having been enter into large period
It is updated to：The large period duration after startup offset mod adjustment before adjustment；If it is determined that large period duration it is elongated, then keep
The startup offset of each group for having been enter into large period is constant.
Mode two, however, it is determined that the large period duration gone out shortens, then by the startup offset of each group for having been enter into large period
It is updated to：The large period duration that former startup offset mod is determined；If it is determined that large period duration it is elongated, then keep it is each
Startup offset into the group of large period is constant；Judge whether the startup offset mod2 after renewal is equal to 0, if so, then by phase
Startup offset is answered to be updated to：Large period duration before and after former startup offset+change is poor.
The difference of aforesaid way one and mode two is：
In mode one, Offset originally biases unnecessary change, smaller relative to the change of large period non-self-adapting scheme,
But after large period is elongated, group paging large period sends uneven, it is possible to causes group to issue congestion；
Method two, it is larger relative to the change of existing large period beep-page message sending method, but after large period is elongated,
Original can be biased to the large period startup offset renewal of even number to the second half section of new large period, therefore, it is possible to seek group
Exhale and uniformly sent in large period, group paging is limited by resource to diminish.
So far, the method flow in the application terminates., can be according to having activated group in the application from above-mentioned flow
Number is determined to send the large period of beep-page message, so that the length of large period can be adjusted in good time, rationally provided using system
Source, improve paging performance.
The foregoing is merely illustrative of the preferred embodiments of the present invention, is not intended to limit the invention, all essences in the present invention
God any modification, equivalent substitution and improvements done etc., should be included within the scope of protection of the invention with principle.
