Description
Technical field
The present invention relates to the mobile communication technology field, relate in particular to the number of adjusting the paging grouping.
Background technology
At LTE (Long Term Evolution, Long Term Evolution) in system, has identical DRX (Discontinuous Reception, discontinuous reception) user of cycle T is divided into nB paging group, the user of same paging group monitors the beep-page message of same calling time (Paging Occasion), detects by the user ID of using oneself after receiving to judge whether to one's name this beep-page message.Only there is 1 paging channel in a calling time, can carry simultaneously 16 users' beep-page message at most.Paging channel is used PDSCH (Physical Downlink Shared Channel, Physical Downlink Shared Channel) carrying, corresponding, also need the relevant dispatch of PDCCH (Physical Downlink ControlChannel, Physical Downlink Control Channel) carrying.
If the paging group number is too much, the paging channel number that needs is also more, can take more expense; If the paging group number is very few, the number of users in each paging group is too much, when the number of users that needs simultaneously paging is more, just might cause congested because of the paging inadequate resource.In addition, when the some users in paging group were paged, the member of whole paging group will resolve beep-page message, and is if paging group is excessive, also comparatively unfavorable to the economize on electricity of terminal.
Therefore, the setting of paging group number nB for the very important effect that ensures of the lifting of power system capacity and system service quality, is therefore an important configuration parameters of Operation ﹠ Maintenance System.Thereby the number that needs the reasonable disposition paging to divide into groups makes under the prerequisite that satisfies certain paging channel congestion probability, and the paging group number is few as much as possible, to save downlink resource.
Common collocation method will rely on following key element to carry out analysis-by-synthesis at present: network planning result, and covering radius is larger, and nB is higher for the paging group number; The community user quantitative forecast, the community user number is more, and nB is higher for the paging group number; Deployment engineer's experience and individual intuition.
There is following problems in present collocation method: rely on manual operation fully, the Operation and Maintenance cost is very high; Can't in time adjust during environmental change; Community user quantity possibility forecasting inaccuracy is true, causes configuration result inaccurate; Undue dependence personal experience and judgement, randomness is larger, is difficult for quantizing, and is wayward.
Therefore, need at present a kind of scheme of adjusting rationally, efficiently, accurately the paging group number.
Summary of the invention
In order one of to address the above problem, the present invention proposes a kind of method of adjusting paging grouping number, comprise the following steps: the paging blocking rate in A, base station measurement measurement period; Described paging grouping number is adjusted according to described paging blocking rate in B, described base station; Described measurement period is adjusted according to the adjustment result of described paging grouping number in C, described base station.
The invention allows for a kind of base station, comprising: measurement module, it is used for measuring the paging blocking rate in measurement period; The grouping adjusting module, it is used for adjusting described paging grouping number according to described paging blocking rate; The cycle adjusting module, it is used for adjusting described measurement period according to the adjustment result of described paging grouping number.
Adopt the method and apparatus of adjustment paging grouping number proposed by the invention, can reduce the Operation and Maintenance cost, accuracy is high, and better service quality and larger throughput are provided, and reduces simultaneously offered load, and makes terminal power saving as far as possible.
