Embodiment
The embodiment of the invention provides a kind of scheme of allocating carrier frequency, in this scheme, the base station can be opened or occlusive part divides carrier frequency according to the state of network, even can solve thus when network is in the spare time in the prior art, all carrier frequency are still all opened the problems that cause a large amount of wastes of base station power consumption.
Before the method that the enforcement embodiment of the invention is introduced, can some carrier frequency be set in operation maintenance center is basic carrier frequency, and other carrier frequency are the stack carrier frequency.Basic carrier frequency can be provided with according to the concrete condition of network, for example, is the most widely if overloading has the covering of certain or some frequencies frequently in the network, is basic carrier frequency with regard to the carrier frequency that this or these frequency is set so; If overloading frequently in the network covering of all frequencies all be much the same, then can select the carrier frequency of one of them or several frequencies arbitrarily is basic carrier frequency.When basic carrier frequency is set, guarantee the continuity that basic carrier frequency covers as far as possible.Under normal conditions, the user used when the capacity of basic carrier frequency was wanted to hold the spare time, thus the number of basic carrier frequency can be according to the spare time time network load condition determine.
After the setting of having introduced basic carrier frequency and stack carrier frequency, will contrast accompanying drawing below the described method of the embodiment of the invention will be described in detail.
Referring to Fig. 1, the allocating carrier frequency method that the embodiment of the invention one provides may further comprise the steps:
Step 101: detect the residing state of network;
In an embodiment of the present invention, two kinds of situations in the time of the state of network can being divided into the spare time and when busy, detecting the residing status method of network has a lot, below two kinds of methods relatively using always is introduced.
The one, static set-up mode promptly can be according to the situation of current network situation and network long-time running in the past, a certain section or a few periods is set when not busy and when busy, when base station system judges according to the time whether network enters the spare time then and when busy.The for example analysis by the user is distributed service time find that every day 00:00-09:00 telephone traffic is obviously less, and the other times telephone traffic is higher, and when then can 10:00-23:59 being set to hurry, and 00:00-09:00 be when being set to the spare time.
The 2nd, dynamic judgment mode, base station system can judge that network is in when busy or during the spare time according to the load of sector or number of users.When load is lower than default load door (or load is lower than default after the time of load thresholding surpasses the default very first time section when not busy) in limited time when not busy, just judge when network enters the spare time; If load is when being higher than default busy hour load thresholding (or load time of being higher than default busy hour load thresholding surpass the second default time period after), just judge that network enters when busy.Above-mentioned when not busy load thresholding and busy hour load thresholding can be same value, also can be set to different values for avoiding producing ping-pong.The very first time section and second time period all can be provided with by timer.
Above-mentioned load can pass through forward emitting power, reverse RSSI (received signal strengthindicator, received signal intensity indication), a kind of measurement in the indexs such as ROT (lifting of making an uproar at the bottom of the ROT Rise Over Thermal), Time Slot Occupancy rate, also can comprehensively weigh by several in these indexs.For example, weigh the load of network with forward emitting power, when the forward direction transmitting power is lower than certain thresholding (thresholding can be provided with, and surpasses rated power 50% as forward emitting power) (or the time that is lower than certain thresholding surpass the default time period after), just judge when network enters the spare time; Otherwise, judge that then network enters when doing.Above-mentioned load also can be the wherein several comprehensive conditions of index such as forward emitting power, reverse RSSI, ROT, Time Slot Occupancy rate, be lower than 5dB such as ROT, and after the time that forward emitting power is lower than rated power 50% surpasses the default time period (default time period can by the timer setting), judge that network enters when busy; Otherwise, judge that then network enters when doing.In addition, also can be that one of them satisfies certain condition in above-mentioned several index, just judge to be lower than 5dB as ROT when network enters the spare time, or after forward emitting power time of being lower than rated power 50% surpasses the default time period, just judge when network enters the spare time; Otherwise, judge that then network enters when doing.
The balancing method of above-mentioned load has a variety of, can't be exhaustive one by one at this, so those skilled in the art can handle flexibly according to the actual conditions of network when using the described method of the embodiment of the invention.
Step 102: when being not busy as if the residing state of network, the user on the carrier frequency that then will superpose is moved to basic carrier frequency;
User on the stack carrier frequency is moved to basic carrier frequency can adopt the Handdown hard handover approach.The Handdown direct-cut operation utilizes and covers basically identical between the different carrier frequency of common sector and with the high characteristics of direct-cut operation success rate in the sector, can the direct command user simultaneously direct-cut operation to the basic carrier frequency of pre-configured basic carrier frequency of same sector Handdown of database and adjacent basic sub-district.
