…… ……
The network data includes the cell number of each signal cell locating for mobile terminal, as mobile terminal had both been in source letter Number cell, being also at signal cell that signal cell, cell number that cell number is 001 are 002 and cell number is 003 Signal cell, then the network data of received mobile terminal include 001,002,003 and source signal cell number (such as source signal is small 000) area's number is.
It include the mobile terminal of at least two cell numbers in S20, locking network data.
In step S20, the mobile terminal in network data including at least two cell numbers is locked, when received each When the network data of a mobile terminal includes at least two cell number, then illustrate that the mobile terminal is small at least in two signals Area is possible to the mobile terminal being switched to another signal cell from source signal cell；When some received mobile terminal Network data when only including a cell number, then illustrate that the mobile terminal is only in source signal cell, can not connect The signal of other signal cells is received, therefore the mobile terminal cannot be switched to other signal cells, and can only be small in source signal Signal is received in area.
S30, in the source signal cell-overload, in the mobile terminal of locking determine network data in include the first mesh The mobile terminal of the cell number of signal cell is marked, and is switched to determining mobile terminal according to preset first switching condition First object signal cell.
In step S30, in source signal cell-overload, resource request information is sent to first object signal cell RESOURCE STATUS REQUEST, if there are surplus resources in the first object signal cell, the first object signal cell meeting Echo message RESOURCE STATUS RESPONSE/UPDATE report the loading condition of itself, if receiving first object letter The echo message RESOURCE STATUS RESPONSE/UPDATE of number cell, then explanation can be by the mobile end of source signal cell End is switched to first object signal cell.The communication pattern phase of the communication pattern of the first object signal cell and source signal cell Together or the communication pattern of the first object signal cell is different from the communication pattern of source signal cell.When first object signal Communication pattern is identical as the communication pattern of source signal cell, then it is balanced to carry out lateral load in this step；When first object is believed Number communication pattern it is different from the communication pattern of source signal cell, then it is balanced to carry out longitudinal load in this step.
It include first object from network data determining in the mobile terminal locked in step S20 in step S30 The mobile terminal of the cell number of signal cell, it is as identical as the communication pattern of source signal cell in worked as first object signal cell, If the communication pattern of source signal cell is WCDMA, then the communication pattern of first object signal cell is also WCDMA, then in step The mobile terminal of the cell number in network data comprising first object signal cell is determined in the mobile terminal locked in S20 (it is WCDMA that i.e. corresponding communication pattern is numbered in first object signal cell), such as the cell number packet of first object signal cell Include cell number 002,004,006, then in the network data in the mobile terminal of locking search include cell number 002, 004,006 mobile terminal such as finds out satisfactory mobile terminal 3, mobile terminal 4 and mobile terminal 5, then will be mobile whole End 3, mobile terminal 4 and mobile terminal 5 are sequentially switched to first object signal cell according to preset first switching condition.When When one echo signal cell is identical as the communication pattern of source signal cell, which includes mobile terminal in source signal The signal strength of cell, the first default switching number threshold values；The first default switching number threshold values can be 50.
It include first object from network data determining in the mobile terminal locked in step S20 in step S30 The mobile terminal of the cell number of signal cell, it is as different from the communication pattern of source signal cell in worked as first object signal cell, If the communication pattern of source signal cell is WCDMA, the communication pattern of first object signal cell is non-WCDMA, i.e. first mesh The communication pattern of signal cell is marked for other communication patterns other than WCDMA, such as the communication of the first object signal cell Mode can be GSM, WLAN.It determines in network data in the mobile terminal then locked in step S20 and believes comprising first object The mobile terminal of the cell number of number cell, as the cell number of first object signal cell include cell number 001,003, 005, then the mobile terminal including cell number 001,003,005 is searched in the network data in the mobile terminal of locking, such as Satisfactory mobile terminal 6, mobile terminal 7 and mobile terminal 8 are found out, then by mobile terminal 6, mobile terminal 7 and movement Terminal 8 is sequentially switched to first object signal cell according to preset first switching condition.When first object signal cell and source When the communication pattern difference of signal cell, which includes the cell number of each signal cell locating for mobile terminal The default switching number threshold values of number, third of corresponding communication pattern.
S40, after carrying out the mobile terminal switching of first object signal cell, and when the source signal cell is still overloaded, Determination is not switched in the first object signal cell in the mobile terminal of locking, and includes the second target in network data The mobile terminal of the cell number of signal cell, and determining mobile terminal is switched to according to preset second switching condition Two echo signal cells；
In step S40, after carrying out the mobile terminal switching of first object signal cell, the source signal cell still mistake When load, then resource request information RESOURCE STATUS REQUEST is sent to the second echo signal cell, if second target There are surplus resources in signal cell, then the second echo signal cell can echo message RESOURCE STATUS RESPONSE/ UPDATE reports the loading condition of itself, if receiving the echo message RESOURCE STATUS of the second echo signal cell RESPONSE/UPDATE, then the mobile terminal of source signal cell can be switched to the second echo signal cell by explanation.When in step In S30, when the communication pattern of first object signal cell is identical as the communication pattern of source signal cell, then the second echo signal is small The communication pattern in area is different from the communication pattern of source signal cell, i.e., when step S30 carries out lateral load equilibrium, then in step It is balanced that S40 carries out longitudinal load；When in step s 30, the communication pattern of first object signal cell and source signal cell it is logical When letter mode difference, then the communication pattern of the second echo signal cell is identical as the communication pattern of source signal cell, that is, works as step When S30 carries out longitudinal load equilibrium, then it is balanced lateral load to be carried out in step S40；The first object signal cell and the second mesh The communication pattern for marking signal cell is different.
In step S40, it is small not to be switched to first object signal for determination from the mobile terminal locked in step S20 Area, and network data includes the mobile terminal of the cell number of the second echo signal cell.Such as when first object in step S30 (lateral switching is carried out) when signal cell is identical as the communication pattern of source signal cell, then the second target in step S40 Signal cell is different from the communication pattern of source signal cell (carry out longitudinal switching), the above-mentioned first object signal cell that is switched to Mobile terminal 3, mobile terminal 4 and mobile terminal 5 include the cell of the second echo signal cell their network data Number, but because they have been switched to first object signal cell, then it cannot be switched to the second echo signal cell again, Therefore in step S40, will not be determined as mobile terminal 3, mobile terminal 4 and mobile terminal 5 that can be switched to the second mesh Mark the mobile terminal of signal cell.If the communication pattern of source signal cell is WCDMA, the communication pattern of first object signal cell Communication pattern for WCDMA, the second echo signal cell is different from the communication pattern of source signal cell, i.e. second echo signal The communication pattern of cell is other communication patterns other than WCDMA, as the communication pattern of the second echo signal cell can Think GSM, WLAN, then determines to include the second echo signal cell in network data in the mobile terminal locked in step S20 Cell number mobile terminal, such as cell number of the second echo signal cell includes cell number 001,003,005, then exists The mobile terminal including cell number 001,003,005 is searched in network data in the mobile terminal of locking, such as finds out symbol Desired mobile terminal 6, mobile terminal 7 and mobile terminal 8 is closed, then by 8 basis of mobile terminal 6, mobile terminal 7 and mobile terminal Preset second switching condition is sequentially switched to the second echo signal cell.When the second echo signal cell and source signal cell When communication pattern difference, which includes the corresponding communication of cell number of each signal cell locating for mobile terminal The number of mode, the second default switching number threshold values.
In step S40, it is small not to be switched to first object signal for determination from the mobile terminal locked in step S20 Area, and network data includes the mobile terminal of the cell number of the second echo signal cell.Such as when first object in step S30 (longitudinal switching is carried out) when the communication pattern difference of signal cell and source signal cell, then the second target in step S40 The communication pattern of signal cell and source signal cell is the same as (carrying out lateral switching), the above-mentioned shifting for being switched to first object signal cell Terminal 6, mobile terminal 7 and mobile terminal 8 are moved, includes the cell volume of the second echo signal cell their network data Number, but because they have been switched to first object signal cell, then it cannot be switched to the second echo signal cell again, because This will not be determined as mobile terminal 6, mobile terminal 7 and mobile terminal 8 that can be switched to the second target in step S40 The mobile terminal of signal cell.If the communication pattern of source signal cell is WCDMA, the communication pattern of first object signal cell is Non- WCDMA, the communication pattern of the second echo signal cell are WCDMA, then determine network number in the movement locked in step S20 (i.e. the cell number of the second echo signal cell is corresponding for the mobile terminal of cell number in comprising the second echo signal cell Communication pattern be WCDMA), such as cell number of the second echo signal cell includes cell number 002,004,006, then is locking The mobile terminal including cell number 002,004,006 is searched in network data in fixed mobile terminal, is such as found out and is met It is required that mobile terminal 3, mobile terminal 4 and mobile terminal 5, then by mobile terminal 3, mobile terminal 4 and mobile terminal 5 according to pre- If the second switching condition be sequentially switched to the second echo signal cell.It is logical when the second echo signal cell and source signal cell When letter mode is identical, which includes that mobile terminal is a in the signal strength of source signal cell, the 4th default switching Number threshold values.
Using the load-balancing method of the heterogeneous network of above-described embodiment, in source signal cell-overload, transverse direction can be passed through Load balancing and the balanced common realization heterogeneous network load balancing of longitudinal load.
Referring to Fig. 2, Fig. 2 is the detailed process schematic diagram of step S10 in Fig. 1, and step S10 includes:
S11, network data feedback request is sent to each mobile terminal in the source signal cell.
In this step, to obtain the received communication network situation of each mobile terminal energy in source signal cell, to place Network data feedback request is sent in each mobile terminal of the source signal cell.Each mobile terminal in the signal cell is connecing When receiving network data feedback request, start the signal that can receive it and carry out signal strength indication measurement (including to believe source Number cell and the signal strength indication of other signal cells measure), and the survey to other signal cells other than source signal cell Magnitude is judged, if the signal strength indication of measurement is greater than preset value THRESH_NET, reports it can received signal intensity The cell number of signal cell where value is greater than the signal of preset value.Progress such as mobile terminal 1 to its signal that can be received Measurement, the cell number that cell number is 000(source signal cell can be received by measuring its), 001,002,003 signal it is small The signal in area, but the signal strength indication of measurement for being 001 in cell number is less than preset value, the then net of the mobile terminal reporting Network data only include cell number 000,002,003.Because if mobile terminal 1 reports cell number 001, then subsequent Balancing procedure in, it is possible to mobile terminal 1 is switched to the signal cell that cell number is 001, but the mobile terminal 1 exists The signal reception for the signal cell that cell number is 001 is simultaneously bad, therefore will affect the communication quality of mobile terminal 1.
S12, the network data that each mobile terminal responds the feedback request and reports is received；Wherein: in the network data Cell number is greater than the cell number group of the signal cell of preset value by the cell number and signal strength indication of the source signal cell At.
In this step, the network data for receiving each mobile terminal response to network data feedback request and reporting, the network Data include cell number, may also include mobile terminal in the signal strength indication of the corresponding signal cell of each cell number.The net Cell number in network data is small greater than the signal cell of preset value by the cell number and signal strength indication of source signal cell Area's number composition.
Referring to Fig. 3, Fig. 3 is the first embodiment flow diagram of step S30 in Fig. 1, when the first object signal cell When identical as the communication pattern of source signal cell, step S30 includes:
S31, in the mobile terminal of locking determine network data in only include first object signal cell cell compile Number mobile terminal, to generate the first balanced list.
In step S31, determine that network data only includes first object signal cell in the mobile terminal of locking Cell number mobile terminal, i.e., Network Search data only include first object signal cell in the mobile terminal of locking Cell number mobile terminal, to generate the first balanced list, such as when the communication module of source signal cell is WCDMA, then the The communication pattern of one echo signal cell is also WCDMA, determines in the mobile terminal locked in step S20 and wraps in network data The mobile terminal of the cell number of the signal cell containing first object, if the cell number of first object signal cell includes that cell is compiled Number 002,004,006, the network data for such as finding out mobile terminal 3, mobile terminal 4 and mobile terminal 5 includes cell number 002, any one or more in 004,006, then first is generated according to mobile terminal 3, mobile terminal 4 and mobile terminal 5 It weighs in list, the first balanced list is as shown in Table 2.
Table two
S32, by the mobile terminal in the first balanced list according to the mobile terminal source signal cell signal strength It is worth ascending order arrangement.
In step S32, to the mobile terminal in the first balanced list according to mobile terminal source signal cell letter Number intensity value carries out ascending order arrangement, can will be strong in the signal of source signal cell so that when subsequent step carries out balanced switching The smaller mobile terminal of angle value is preferentially switched to first object signal cell.
