Abstract
The invention discloses a carrier frequency allocating method and device. The method includes that number of weighting users of each carrier frequency in available carrier frequency set is acquired, wherein the number of weighting users of each carrier frequency is determined by number of actual users of the carrier frequency and orders of each actual user; and after determining that recommended carrier frequency is not existed in the available carrier frequency set, carrier frequency with the minimum number of weighting users in the available carrier frequency set is acquired and the carrier frequency is taken as the carrier frequency to be allocated. According to the technical scheme provided by the invention, the problem that load is not balanced between carrier frequencies as carrier frequency allocation is carried out according to the traditional method in related technology, thus effectively and equally allocating users in different orders onto each carrier frequency and achieving full resource utilization and load sharing.
Description
Technical field
The present invention relates to the communications field, in particular to a kind of carrier distribution method and device.
Background technology
In the last few years, mobile communcations system had obtained fast development all over the world, and especially along with the continuous increase of people to the data business demand, HRPD Rev A system is widely used in commercialization in increasing country.Use mobile communcations system, people not only can satisfy the basic audio demand that contacts whenever and wherever possible, can also be by when terminal be watched streaming media service glibly, carry out video request program, game on line, the Internet telephony (Voiceover Internet Protocol, referred to as VoIP) etc., thereby enriched greatly people's life.
But, along with being on the increase of user and class of business, they are to code division multiple access (Code Division Multiple Access, referred to as CDMA), evolution data (Evolution Data Only, referred to as EVDO) network proposed to be different from service quality (QoS) requirement that traditional data is used, and therefore need to carry out to the user division of different brackets, to satisfy the demand of different user.For example, in our HRPD Rev A system, we are divided into following 4 grades to the user:
| User gradation | QoSClassID | The forward direction flank speed | The forward direction minimum speed limit | Reverse flank speed |
| 3：Gold | 2 | 2M | 100K | 200K |
| 2：Silver | 2 | 1M | 50K | 100K |
| 1：Copper | 1 | 1M | 0 | 50K |
| 0：Default | 1 | 1M | 0 | 50K |
As can be seen from the above table, the user of each grade is different to the demand of network.
In the correlation technique, present carrier frequency selection and allocation algorithm are as follows: base station system is distributed equally according to actual user's number on the basis of considering each carrier frequency availability.But, support in base station and terminal in different brackets user's the situation that because each user is to the transmission digit rate of network, the requirement of time delay is all different, therefore, the load of the carrier frequency of carrying different user also is different.If still carry out according to the conventional method carrier frequency distribution, just might the many user of occupied bandwidth all centralized distribution on same carrier frequency, for example, Gold user in the upper table all concentrates on a carrier frequency, Default user then concentrates on another carrier frequency, has just caused the unbalanced situation of load between carrier frequency; Well do not reach the effect of resource reasonable distribution.
Summary of the invention
For carrying out according to the conventional method carrier frequency distribution in the correlation technique, cause between carrier frequency the unbalanced problem of load and propose the present invention, for this reason, main purpose of the present invention is to provide a kind of carrier frequency distribution scheme, one of to address the above problem at least.
According to an aspect of the present invention, provide a kind of carrier distribution method.
Carrier distribution method according to the present invention comprises: obtain the weighting number of users that available carrier frequencies is concentrated each carrier frequency, wherein, the weighting number of users of each carrier frequency is by the actual user's number that uses this carrier frequency and each actual user's classification; Determining that available carrier frequencies is concentrated does not exist the recommendation carrier frequency, obtain that available carrier frequencies is concentrated the carrier frequency of weighting number of users minimum and with this carrier frequency as carrier frequency to be allocated.
According to a further aspect in the invention, provide a kind of carrier frequency distribution device.
Carrier frequency distribution device according to the present invention comprises: acquiring unit, be used for obtaining the weighting number of users that available carrier frequencies is concentrated each carrier frequency, and wherein, the weighting number of users of each carrier frequency is by the actual user's number that uses this carrier frequency and each actual user's classification; Allocation units are used for concentrating in definite available carrier frequencies not existing in the situation of recommending carrier frequency, the carrier frequency that obtains the concentrated weighting number of users minimum of available carrier frequencies also with this carrier frequency as carrier frequency to be allocated.
By the present invention, adopt a kind of carrier distribution method of new support different user grade, according to the different user grade, a user gradation weight is set, then carry out carrier frequency distribution according to the weighting number of users that calculates, solved and carried out according to the conventional method carrier frequency distribution in the correlation technique, cause the unbalanced problem of load between carrier frequency, and then can be effectively user's mean allocation of different brackets to each carrier frequency, reach taking full advantage of and load sharing of resource.
