It should be noted that, the network equipment in embodiment of the present invention scheme can be Home eNodeB (as Femto base station), can be also macro base station.The scheme of the embodiment of the present invention is applicable to global system for mobile communications (GSM, Global System for Mobile Communications), TD SDMA (TD-SCDMA, Time Division-Synchronous Code Division Multiple Access) system, Wideband Code Division Multiple Access (WCDMA) (WCDMA, Wideband Code Division Multiple Access) system, Long Term Evolution (LTE, Long Term Evolution) system and timesharing Long Term Evolution (TD-LTE, Time Division-Long Term Evolution) system.
Below in conjunction with Figure of description, embodiments of the present invention is further illustrated, but the present invention is not limited to the following examples.
Embodiment mono-:
As shown in Figure 1, the embodiment of the present invention one intermediate-frequeney point collocation method comprises the following steps:
Step 101: network equipment is determined the frequency that needs renewal according to the interference value of the frequency of current use;
Step 102: network equipment is selected M frequency except the frequency of current use from available frequency;
Step 103: the frequency that network equipment upgrades needs according to the frequency of selecting upgrades processing.
Alternatively, before step 101, can carry out following steps:
Network equipment determines that service quality does not meet transmission quality requirements.
Particularly, network equipment can be in following condition partly or entirely meet after, determine that service quality does not meet transmission quality requirements:
Condition one: cutting off rate is greater than first threshold;
Condition two: handover success rate is less than Second Threshold;
Condition three: cell update mortality is greater than the 3rd threshold value.
Wherein, cutting off rate is greater than first threshold and represents that the terminal in network equipment coverage cannot communicate by letter normally; Handover success rate is less than Second Threshold and represents that the terminal that accesses above-mentioned network equipment is difficult to successful switch; Cell update mortality is greater than the 3rd threshold value and represents that terminal is difficult to again access to above-mentioned network equipment.First threshold, Second Threshold and the 3rd threshold value can be set based on experience value.
It should be noted that; network equipment determines that service quality does not meet transmission quality requirements; be not limited to above-mentioned condition, so long as can embody network equipment, cause condition that service quality declines all within the scope of embodiment of the present invention scheme protection because of external disturbance.
Network equipment determines that service quality does not meet transmission quality requirements, represents that network equipment is subject to external disturbance stronger, now, can detect external disturbance, determines in the frequency of current use, is subject to the frequency that external disturbance is stronger.It should be noted that, before determining the frequency that needs to upgrade, determine that service quality does not meet transmission quality requirements, can effectively reduce the signaling consumption of base station.This be because, when if service quality meets transmission quality requirements, also the frequency determine to need upgrading, will cause base station ceaselessly the interference value of the frequency of current use to be detected, and the interference value of frequency to be the measured value reporting according to the physical layer of base station determine.
In step 101, the frequency that the needs that network equipment is determined upgrade may have a plurality of.Particularly, network equipment can be determined the frequency that needs renewal in the following manner:
Each frequency for current use is carried out respectively:
Cycle is determined the interference value of this frequency; Determine that in definite interference value of N cycle, interference value is greater than the number of the 4th threshold value, N is positive integer; When the number of determining is greater than the 5th threshold value, determine the frequency of this frequency for needing to upgrade.
Alternatively, network equipment also can be determined the frequency that needs renewal in the following manner:
Each frequency for current use is carried out respectively:
Cycle is determined the interference value of this frequency; Determine the mean value of the interference value that N cycle is definite; When the mean value of determining is greater than the 6th threshold value, determine the frequency of this frequency for needing to upgrade.
Alternatively, network equipment also can be determined the frequency that needs renewal in the following manner:
Each frequency for current use is carried out respectively:
Determine the interference value of this frequency, when the interference value of this frequency is greater than the 7th threshold value, determines the frequency of this frequency for needing to upgrade, and the interference value in N cycle of this frequency is not added up.
The 4th threshold value, the 6th threshold value, the 7th threshold value can be set to identical value as required, also can be set to different values.
Particularly, take network equipment as Home eNodeB be example, the physical layer of Home eNodeB can report the measured value for each frequency of current use to Home eNodeB at each report cycle.The measured value that Home eNodeB reports physical layer with a treatment cycle is processed, and obtains the interference value of current use frequency.Wherein, treatment cycle is not less than report cycle, the interference value that is to say the frequency that a treatment cycle is determined can be that the measured value reporting according to a plurality of report cycles is determined, the mean value of the measured value that the interference value of the frequency that for example, treatment cycle is determined can report for a plurality of report cycles.Wherein, received total wideband power (the RTWP that the measured value that physical layer reports can report for physical layer, Received Total Wideband Power), Interference Signal Code Power (ISCP, Interface Signal Code Power), signal-to-jamming ratio (SIR, Signal to Interference Ratio), transmission channel Block Error Rate (BLER, transport channel BLock Error Rate) or transmission channel bit error rate (Transport channel Bit Error Rate) etc.
In specific implementation process, a frequency for current use, the interference value of this frequency that can obtain when pre-treatment according to Home eNodeB determines that whether this frequency is to need the frequency that upgrades, and the interference value that also can process this frequency that obtain according to N treatment cycle determines whether this frequency is the frequency that needs renewal.
If determine the frequency of a frequency for needing to upgrade, represent that this frequency is subject to external disturbance stronger, therefore,, if continue to use this frequency may cause the service quality of Home eNodeB poor, access the terminal of this Home eNodeB and cannot use this frequency normally to commence business.After determining the frequency that needs to upgrade, reconfigurable frequency, to reduce the suffered interference of Home eNodeB.
In step 102, available frequency is pre-configured, in specific implementation process, can be in advance for Home eNodeB configures available frequency list, and Home eNodeB can be selected the frequency needing from available frequency list.Wherein, the available frequency of Home eNodeB can be the whole frequencies in available bandwidth, also can be configured according to the frequency planning of operator.
Particularly, the specific implementation of step 102 can be:
Step 1: network equipment is carried out respectively for each frequency except the frequency of current use in available frequency: the received signal strength value of determining this frequency;
Step 2: network equipment is selected M frequency of received signal strength value minimum except the frequency of current use from available frequency.
Wherein, M is for needing the quantity of the frequency of renewal, and value is positive integer.For example, suppose that the frequency of the needs renewal that step 101 is determined has two, the value of M is 2.
Particularly, Home eNodeB can obtain the available frequency list of self, and the frequency of current use is deleted from available frequency list, remaining frequency, as alternative frequency, is below called alternative frequency by the frequency except the frequency of current use in available frequency.For each frequency in alternative frequency, Home eNodeB can be intercepted this frequency respectively, the broadcast singal quantity of the adjacent cell of this frequency of use of determining the received signal strength value of this frequency and receiving, wherein, the received signal strength value of this frequency is less, represents that the interference that the Home eNodeB of this community uses this frequency to be subject to is less.If the received signal strength value of this frequency is 0, the Home eNodeB that represents this community does not listen to adjacent cell and uses this frequency; If the received signal strength value of frequency is not 0, the Home eNodeB that represents this community listens to adjacent cell and uses this frequency.Wherein, the received signal strength value of frequency can be received signal strength indicator (RSSI, Received Signal Strength Indicator).
Therefore, in specific implementation process, can be from alternative frequency M frequency of selective reception signal strength values minimum, so just can guarantee that the frequency that Home eNodeB is used does not repeat, and the frequency of selecting is subject to the interference of adjacent cell less.For example, suppose that alternative frequency comprises frequency 1～frequency 6, its corresponding received signal strength value is respectively 0,1,2,3,4,5, and the quantity of the frequency that the needs that step 101 is determined upgrade has two, that is to say in the frequency of the current use of Home eNodeB and have two frequencies to be subject to external disturbance stronger, now can from frequency 1～frequency 6, select frequency 1 and frequency 2.
Distinguishingly, if having received signal strength value in alternative frequency is 0 frequency, and the quantity of the frequency that received signal strength value is 0 is greater than M, the frequency that is 0 from received signal strength value, select and received signal strength value is not M frequency of the absolute value sum maximum of the frequency difference between each frequency of 0.
Particularly, the frequency that is 0 for each received signal strength value is carried out respectively: determine that each received signal strength value in this frequency and alternative frequency is not the absolute value of the frequency difference of 0 frequency, and determine above-mentioned absolute value sum.The frequency that is 0 from received signal strength value, select M frequency of absolute value sum maximum.
For example, suppose that alternative frequency comprises frequency 1～frequency 6, its corresponding received signal strength value is respectively 0,0,0,3,4,5, and the frequency of frequency 1～frequency 6 correspondences is respectively f1～f6, the value of M is 2, the received signal strength value of frequency 1～frequency 3 is 0, and now, the absolute value sum ff1 of the frequency difference between frequency 1 and frequency 4～frequency 6 can be expressed as:
ff1＝|f1-f4|+|f1-f5|+|f1-f6| [1]
The absolute value sum ff2 of the frequency difference between frequency 2 and frequency 4～frequency 6 can be expressed as:
ff2＝|f2-f4|+|f2-f5|+|f2-f6| [2]
The absolute value sum ff3 of the frequency difference between frequency 3 and frequency 4～frequency 6 can be expressed as:
ff3＝|f3-f4|+|f3-f5|+|f3-f6| [3]
If ff1>ff2>ff3, using frequency 1 and frequency 2 as the frequency of selecting.
If not having received signal strength value in alternative frequency is 0 frequency, and the quantity of the frequency of received signal strength value minimum is greater than M, from the frequency of received signal strength value minimum selective reception to M the frequency of broadcast singal minimum number of adjacent cell.
For example, suppose that alternative frequency comprises frequency 1～frequency 6, its corresponding received signal strength value is respectively 1,1,1,3,4,5, the value of M is 2, and on frequency 1, listen to the broadcast singal that 3 adjacent cells send, on frequency 2, listen to the broadcast singal that 2 adjacent cells send, on frequency 3, listen to the broadcast singal that 1 adjacent cell sends, using frequency 2 and frequency 3 as the frequency of selecting.
Distinguishingly, if the frequency that the needs that step 101 is determined upgrade is a frequency, the specific implementation of step 102 can be:
If the frequency that received signal strength value is 0 only has one, this frequency that selective reception signal strength values is 0; If it is a plurality of that the frequency that received signal strength value is 0 has, the frequency that is 0 from received signal strength value, select and received signal strength value is not the frequency of the absolute value sum maximum of the frequency difference between each frequency of 0; If there is no received signal strength value is 0 frequency, the frequency of selective reception signal strength values minimum; If there do not have received signal strength value to be that the frequency of 0 frequency and received signal strength value minimum has to be a plurality of, the frequency of the broadcast singal minimum number of the adjacent cell that selective reception is arrived.
That is to say, if only have a frequency not to be listened in alternative frequency, the received signal strength value of only having a frequency is 0, using this frequency as the frequency of selecting.For example, suppose that alternative frequency comprises frequency 1～frequency 6, its corresponding received signal strength value is respectively 0,1,2,3,4,5, directly using frequency 1 as the frequency of selecting.
If there are a plurality of frequencies not all to be listened, the frequency that received signal strength is 0 exists a plurality of, and the frequency that can not be listened for each is carried out respectively:
Determine the absolute value of the frequency difference of each frequency being listened in this frequency and alternative frequency, and determine above-mentioned absolute value sum.
In the frequency being never listened, select the frequency of absolute value sum maximum.
For example, suppose that alternative frequency comprises frequency 1～frequency 6, its corresponding received signal strength value is respectively 0,0,2,3,4,5, and the frequency of frequency 1～frequency 6 correspondences is respectively f1～f6, frequency 1 is 0 with the received signal strength value of frequency 2, now, the absolute value sum ff1 of the frequency difference between frequency 1 and frequency 3～frequency 6 can be expressed as:
ff1＝|f1-f3|+|f1-f4|+|f1-f5|+|f1-f6| [4]
The absolute value sum ff2 of the frequency difference between frequency 2 and frequency 3～frequency 6 can be expressed as:
ff2＝|f2-f3|+|f2-f4|+|f2-f5|+|f2-f6| [5]
If ff1>ff2, using frequency 1 as the frequency of selecting.
If alternative frequency is all listened, the frequency of selective reception signal strength values minimum.For example, suppose that alternative frequency comprises frequency 1～frequency 6, its corresponding received signal strength value is respectively 1,2,3,4,5,6, using frequency 1 as the frequency of selecting.
If alternative frequency is all listened and the frequency of received signal strength value minimum have a plurality of, the frequency of the broadcast singal minimum number of the adjacent cell that selective reception is arrived.Wherein, for a frequency, if the broadcast singal quantity of the adjacent cell receiving on this frequency is fewer, the quantity of the adjacent cell of this frequency of expression use is fewer, and the interference that this frequency is subject to will be less.For example, suppose that alternative frequency comprises frequency 1～frequency 6, its corresponding received signal strength value is respectively 1,1,2,3,4,5, and on frequency 1, listen to the broadcast singal that 3 adjacent cells send, on frequency 2, listen to the broadcast singal that 2 adjacent cells send, using frequency 2 as the frequency of selecting.
After selecting frequency, the frequency that can upgrade needs according to the frequency of selecting upgrades processing, performs step 103.Particularly, can from M the frequency of selecting, be followed successively by each frequency that need to upgrade and select frequency, utilize the frequency of selecting to replace the frequency that needs renewal.For example, suppose that needing the frequency upgrading is frequency 1 ' and frequency 2 ', 2 frequencies selecting are respectively frequency 1, frequency 2, frequency 1 ' can be replaced with to frequency 1, frequency 2 ' is replaced with to frequency 2, certainly, also frequency 1 ' can be replaced with to frequency 2, frequency 2 ' is replaced with to frequency 1.
Network equipment, after frequency needs being upgraded according to the frequency of selecting upgrades processing, can notify the frequency after upgrading the frequency transmitting data with indicating terminal after renewal to the terminal in network equipment coverage.
Alternatively, network equipment is after determining the frequency that needs to upgrade, before the frequency that needs are upgraded upgrades and processes, forbid needing described in service access on the carrier wave of the frequency that upgrades, and the business of transmitting that may exist on the carrier wave of the frequency of needs renewal is processed.Particularly, network equipment can judge on the carrier wave of the frequency need upgrading whether have the business of transmitting, if exist, this business is switched to adjacent cell; Or this business is switched on other carrier waves of network equipment; Or judge in this business and whether comprise and flow class and/or session service, if comprise stream class and/or session service in this business, one timer is set, if above-mentioned stream class and/or session service finished before timer expires, the business of transmitting on the carrier wave of the frequency that interruption need to be upgraded; If above-mentioned stream class and/or session service do not finish when timer expires, the business of transmitting on the carrier wave of the frequency that interruption need to be upgraded; If do not comprise stream class and/or session service in this business, the business of transmitting on the carrier wave of the frequency that interruption need to be upgraded.
Alternatively, the business of transmitting on the carrier wave of the frequency if desired upgrading cannot switch to adjacent cell, further this business is switched on other carrier waves of network equipment.
Alternatively, the business of transmitting on the carrier wave of the frequency if desired upgrading cannot switch on other carrier waves of network equipment, further judge in this business and whether comprise and flow class and/or session service, if, one timer is set, if above-mentioned stream class and/or session service finished before timer expires, the business of transmitting on the carrier wave of the frequency that interruption need to be upgraded; If above-mentioned stream class and/or session service do not finish when timer expires, the business of transmitting on the carrier wave of the frequency that interruption need to be upgraded; If do not comprise stream class and/or session service in this business, the business of transmitting on the carrier wave of the frequency that interruption need to be upgraded.
As shown in Figure 2, the schematic flow sheet for network equipment is processed the business of transmitting that may exist on the carrier wave of the frequency of needs renewal, comprises the following steps:
Step 201: whether have the business of transmitting on the carrier wave of the frequency that network equipment judgement need to be upgraded, if so, go to step 202; Otherwise flow process finishes.
Step 202: network equipment judges whether the business of transmitting on the carrier wave of the frequency of needs renewal to be switched to adjacent cell, if so, goes to step 203; Otherwise, go to step 204.
Step 203: the business of transmitting on the carrier wave of the frequency that network equipment need to upgrade this switches to adjacent cell, returns to step 201.
Wherein, network equipment can preferentially switch to by this business the adjacent cell that signal strength signal intensity is the strongest.
Step 204: network equipment judges whether the business of transmitting on the carrier wave of the frequency of needs renewal to be switched on other carrier waves of network equipment, if so, goes to step 205; Otherwise, go to step 206.
Step 205: the business of transmitting on the carrier wave of the frequency that network equipment need to upgrade this switches on other carrier waves of network equipment, returns to step 201.
Wherein, network equipment can preferentially switch to this business on the carrier wave of the less frequency of being disturbed of network equipment, and the frequency point information after switching is notified to terminal.
Step 206: whether comprise stream class and/or session service in the business of transmitting on the carrier wave of the frequency that network equipment judgement need to be upgraded, if so, go to step 207; Otherwise, go to step 210.
Wherein, stream class service comprises video traffic, and session service comprises speech business.
Step 207: timer is set, goes to step 208.
Step 208: network equipment judges that whether above-mentioned stream class and/or session service finished before this timer expires, and if so, went to step 210; Otherwise, go to step 209.
Step 209: waiting timer expires, goes to step 210.
