Multiple independent frequency points of multiple operators of this base station shared, an operator pair can be configured on sharing base Answer an independent frequency point, this frequency the only user for this operator use, and the corresponding independent frequency point of operator only broadcasts this No. PLMN of operator；The multiple shared frequency of multiple operators of this base station shared can also be configured on sharing base, one Operator corresponds to a shared frequency, and the user that this frequency is available for the plurality of operator uses, and an operator is corresponding shared Frequency broadcasts No. PLMN of the plurality of operator simultaneously.
The application scenarios of method provided in an embodiment of the present invention are as shown in figure 1, be configured with two shared frequencies in sharing base Point f1And f2, f1Power be more than f2Power, the UE in the embodiment of the present invention be located at f1The cell covering and f2The cell covering Public domain, and UE can support this two frequency bins, and in UE access network, acquiescence resides in the larger frequency of power and covers The cell of lid, just because of this reason, leads to f1The cell covering and f2The cell load covering is unbalanced, f2Frequency resource It is wasted, the embodiment of the present invention proposes a kind of method of balance network loads based on this problem.
Embodiments provide a kind of method of balance network loads, as shown in Fig. 2 including：
201st, the shared frequency of sharing base monitoring first covers first community and the second shared frequency covers second little First load difference in area.
Wherein, the first shared frequency and the second shared frequency are the frequency configure in sharing base, the first shared frequency Power be more than the power of the second shared frequency.
When implementing, sharing base can obtain the load of first community and the load of second community to step 201, right The load of first community and the load of second community obtain the load difference of first community and second community as difference.Specifically, altogether Enjoy base station can by the utilization rate of Physical Resource Block (physical resource block, abbreviation PRB) in cell and/ Or the connection quantity of wireless heterogeneous networks (Radio Resource Control, abbreviation RRC) obtains the load of cell.
In conjunction with the scene shown in Fig. 1, the first shared frequency can be f1, the second shared frequency can be f2.
202nd, when the first load difference is more than the first predetermined threshold value, sharing base broadcast first on the first shared frequency is System message.
Wherein, the first system message includes being higher than the letter of the priority of first community for the priority representing second community Cease, start alien frequencies switching condition to high priority cell re-selection conditions and first, to high priority cell re-selection conditions be：Second The cell selection signal of cell receives the difference that level value is more than the first default value and the first bias, and the first default value is to height The default threshold score of priority cell reselection conditions；First starts alien frequencies switching condition is：The signal strength signal intensity of second community is more than Second default value and the difference of the second bias, the second default value is the default threshold score starting alien frequencies switching condition, and first is pre- If threshold value, the first bias and the second bias are all higher than 0.
It should be noted that system message include to high priority cell re-selection conditions, start alien frequencies switching condition And hereinafter mention startup different-frequency measure condition, to low priority cell re-selection conditions and stop different-frequency measure condition be Cell-level configures, therefore, reselection conditions in sharing base the first system message of broadcast on the first shared frequency (or switching Condition) the Idle state UE (or connected state UE) that is only used in first community carries out using during gravity treatment (or switching), rather than the Idle state UE (or connected state UE) in two cells carries out using during gravity treatment (or switching), Idle state UE in second community (or Connected state UE) reselection conditions (or switching condition) comprising in the system message that frequency sends are shared second according to sharing base Carry out gravity treatment (or switching).
First predetermined threshold value, the first bias and the second bias can determine according to practical application scene, but these Value is unsuitable too small, otherwise, because the Idle state UE (or connected state UE) in first community is still difficult to meet above-mentioned reselection conditions (or switching condition), thus affect the efficiency of balance network loads.For example, the first predetermined threshold value can be 30% or 25% etc., First bias can be 10dB or 15dB, and the second bias can be 10dBm or 15dBm.
203rd, UE receives the first system message of sharing base broadcast, and UE is located at the public area of first community and second community In domain and UE is the UE residing in first community.
204th, when UE is in Idle state, UE according to the first system message include for representing the preferential of second community Level determines that second community is high priority cell, if UE determines the cell of second community higher than the information of the priority of first community Selection signal receive that level value meets that the first system message includes to high priority cell re-selection conditions, UE is to high priority Cell reselection；When UE is in connected state, if UE determines that the signal strength signal intensity of second community meets what the first system message included First startup alien frequencies switching condition, UE carries out cell switching.
Specifically, the cell selection signal of second community is received level value and be designated as S2, then when Idle state UE determines S2＞ Threshhigh-ΔhighWhen, Idle state UE meets to high priority cell re-selection conditions, wherein, ThreshhighFor the first acquiescence Value, ΔhighFor the first bias.
In embodiments of the present invention, first by the priority higher than first community of the priority setting of second community, the Idle state UE in one cell, after receiving the first system message, determines that second community is high priority cell, UE measurement the The cell selection signal of two cells receives level value S2, and judge S2＞ Threshhigh-ΔhighWhether set up, if so, Idle state UE carries out cell reselection, due to high priority cell re-selection conditions being：S2＞ Threshhigh-ΔhighSo that Idle state UE is more Plus readily satisfy to high priority cell re-selection conditions, thus the load difference in first community and second community is preset more than first By transferring in second community the part Idle state UE in first community by cell reselection during threshold value, realize load all Weighing apparatus.
Specifically, the signal strength signal intensity of second community is designated as P2, then first startup alien frequencies switching condition be：P2＞ Pthre2- Δoffset2, wherein, Pthre2Second default value, Δoffset2For the second bias.
Connected state UE in first community, after receiving the first system message, measures P2, and judge P2＞ Pthre2- Δoffset2Whether set up, if so, connected state UE carries out alien frequencies switching, because the first startup alien frequencies switching condition is：P2＞ Pthre2-Δoffset2So that connected state UE is more prone to meet the condition starting alien frequencies switching, thus in first community and second The load difference of cell is more than during the first predetermined threshold value by the part connected state UE in first community is passed through cell switched and transferred To in second community, realize load balancing.
Step 204 when implementing, when UE is in connected state, if UE determines that the signal strength signal intensity of second community meets the The first startup alien frequencies switching condition that one system message includes, UE carries out cell switching, including：
When UE is in connected state, if UE determines that the priority of second community is higher than the priority and second of first community The signal strength signal intensity of cell meets the first startup alien frequencies switching condition, and UE carries out cell switching.
Method provided in an embodiment of the present invention, is more than the first predetermined threshold value in the load difference of first community and second community When, the cell re-selection conditions in the first system message of sharing base broadcast make the Idle state UE in first community be more easy to occur Gravity treatment, the cell switching condition in the first system message of broadcast makes connected state UE be more easy to switch, thus little by first Part UE in area is transferred in second community, realizes the load balancing of network system it is therefore prevented that second shares frequency resource Waste.
And, in the present invention it is whether load difference according to first community and second community determines more than the first predetermined threshold value Whether make the UE in first community carry out gravity treatment or switching, therefore, compare directly according to first community and second community Payload determines whether so that the UE in first community carries out gravity treatment or switching is compared, and can prevent UE from frequently switching little Area, reduces the signaling consumption of network.
Optionally, the first startup different-frequency measure condition and the first stopping different-frequency measure bar are also included in the first system message Part, first starts different-frequency measure condition is：The signal strength signal intensity of first community be less than the 3rd default value and the 3rd bias and, the Three default values are the default threshold score starting different-frequency measure condition；First stops different-frequency measure condition is：The signal of first community Intensity is more than the sum of the 4th default value and the 4th bias, and the 4th default value is the default threshold score stopping different-frequency measure condition, 3rd bias and the 4th bias are all higher than 0.
In the case of being somebody's turn to do, when UE is in connected state, if UE determines that the signal strength signal intensity of first community meets the first startup alien frequencies Measuring condition, UE starts different-frequency measure；If UE determines that the signal strength signal intensity of first community meets the first stopping different-frequency measure condition, UE Stop different-frequency measure.
Wherein, the 3rd bias and the 4th bias can determine according to practical application scene, exemplary, the 3rd biasing Value can be 10dBm or 15dBm, and the 4th bias can be 15dBm or 20dBm.
The signal strength signal intensity of first community is designated as P1, then first startup different-frequency measure condition be：P1＜ Pthre3+Δoffset3, Wherein, Pthre3I.e. the 3rd default value, Δoffset3For the 3rd bias.
Connected state UE in first community, after receiving the first system message, determines P1, and judge P1＜ Pthre3+ Δoffset3Whether set up, if so, start different-frequency measure, because the first startup different-frequency measure condition is：P1＜ Pthre3+Δoffset3, Connected state UE is made to be more prone to meet the condition starting different-frequency measure.
This optional method, it is also possible that the connected state UE in first community is more difficult meets the bar stopping different-frequency measure Part it is ensured that switching from connected state UE in first community to second community.
Optionally, after step 202, method also includes：If sharing base determines that the second load difference is less than second and presets Threshold value, sharing base broadcasts second system message on the first shared frequency, and second system message is included for representing that first is little The priority in area be higher than second community the information of priority, first to low priority cell re-selection conditions, second startup alien frequencies Measuring condition, the second startup alien frequencies switching condition and the second stopping different-frequency measure condition；First to low priority cell reselection bar Part is：The cell selection signal of second community receives level value and is more than the 5th default value, and the 5th default value is little to low priority The default threshold score of area's reselection conditions；Second starts different-frequency measure condition is：The signal strength signal intensity of first community is less than the 3rd acquiescence Value；Second starts alien frequencies switching condition is：The signal strength signal intensity of second community is more than the second default value；Second stopping different-frequency measure bar Part is：The signal strength signal intensity of first community is more than the 4th default value, and the second predetermined threshold value is less than the first predetermined threshold value, the second load difference The first community redefining after broadcast the first system message for sharing base and the load difference of second community.
In the case of being somebody's turn to do, after step 204, UE also executes following steps：UE receives sharing base in the first shared frequency The second system message of upper broadcast；When UE is in Idle state, UE is higher than the excellent of second community according to the priority of first community The information of first level determines that second community is low priority cell, if UE determines that the cell selection signal of second community receives level value Meet first to low priority cell re-selection conditions, UE is to low priority cell reselection；When UE is in connected state, if UE determines The signal strength signal intensity of first community meets the second startup different-frequency measure condition and signal strength signal intensity satisfaction second startup of second community is different Frequency switching condition, UE carries out cell switching；If UE determines that the signal strength signal intensity of first community meets the second stopping different-frequency measure condition, UE stops different-frequency measure.
This optional method, sharing base, after broadcast the first system message, starts balance network load, until load When difference is less than the second predetermined threshold value, just send second system message, due to the Idle state UE (or connected state UE) in first community According to the reselection conditions (or switching condition) in second system message, gravity treatment (or switching) is less likely to occur, therefore, when shared base It is believed that balance network load terminates during broadcast second system message of standing.
During balance network load, if just terminate the flat of load when load difference is just below the first predetermined threshold value Weighing apparatus, then, load difference is easy to and can reach the first predetermined threshold value, then sharing base starts balance network load again, this Sample can lead to substantial amounts of signaling consumption, therefore, so that load difference is less than the second predetermined threshold value (second in the embodiment of the present invention Predetermined threshold value is less than the first predetermined threshold value) when terminate the balance that loads, the occurrence of can prevent this.
Optionally, after sharing base broadcast second system message on the first shared frequency, said method also includes： Sharing base judges whether the 3rd load difference is more than the first predetermined threshold value, and if so, sharing base is shared on frequency again first Broadcast the first system message, if it is not, sharing base continues to broadcast second system message on the first shared frequency；3rd load difference Broadcast the load difference of the first community redefining after second system message and second community for sharing base.
During balance network load, if begin to the flat of load when load difference is just above the second predetermined threshold value Weighing apparatus, then, load difference is easy to and can be less than the second predetermined threshold value, then sharing base terminates balance network load again, this Sample can lead to substantial amounts of signaling consumption, therefore, so that load difference is higher than the first predetermined threshold value (first in the embodiment of the present invention Predetermined threshold value is more than the second predetermined threshold value) when start the balance that loads, the occurrence of can prevent this.
Optionally, said method also includes：Sharing base broadcasts the 3rd system message on the second shared frequency, and the 3rd is System message include for the priority representing second community be higher than first community priority information, second to low priority Cell re-selection conditions and the 3rd stopping different-frequency measure condition；Second to low priority cell re-selection conditions is：Second community little Area's selection signal receives the difference that level value is less than the 5th default value and the 5th bias, and the 5th default value is little to low priority The default threshold score of area's reselection conditions；3rd stops different-frequency measure condition is：The signal strength signal intensity of second community is more than the 4th acquiescence Value and the difference of the 6th bias, the 5th bias and the 6th bias are all higher than 0.
Wherein, the 5th bias and the 6th bias can determine according to actual application scenarios, for example, the 5th bias Can be 20dB, the 6th bias can be 20dBm.
This optional method, by being set to second to low priority cell re-selection conditions：The cell choosing of second community Select signal receive level value be less than the 5th default value and the 5th bias difference so that the Idle state UE in second community more Difficult generation gravity treatment, so that stable the residing in second community of the Idle state UE in second community, by the 3rd is stopped Different-frequency measure condition setting is：The signal strength signal intensity of second community is more than the difference of the 4th default value and the 6th bias so that the Connected state UE in two cells is more prone to meet stopping different-frequency measure condition, so that the connected state UE in second community is steady Fixed reside in second community it is therefore prevented that pingpang handoff in first community and second community for the UE.
