Fig. 1 shows the implementation flow chart of frequency point measurement control method provided in an embodiment of the present invention, in the present embodiment,
The executive agent of flow is base station, and the base station types such as including but not limited to eNB, details are as follows for implementation process：
In step S101, base station receives the frequency points that can measure of the UE of reported by user equipment UE and the UE can
The maximum value of the frequency points of measurement.
In communication system, there are a variety of situations, and UE to be needed to measure multiple frequency points.For example, the serving cell received due to UE
Signal quality be deteriorated caused by switching, due to UE carry out speech business caused by switch etc..Either any situation, by
Base station carries out frequency point to UE and measures control, determines the frequency point for needing UE to measure.Base station determines that UE needs the frequency point measured therein
One foundation is the performance with reference to UE itself.
Existing third generation partner program (the3rd Generation Partnership Project,
The frequency points that UE can be measured are defined in technical specification (Technical Specification, TS) 36.133 3GPP)
Minimum value, which is that the minimum when isosystem measurement or alien frequencies homologous ray are measured to UE frequency point measurement capabilities requires,
The UE of each terminal device manufacturer production must reach this minimum and require.Base station is not required to UE and reports and can obtain according to protocol conventions
Know the minimum value, but there is no the maximum values of the regulation UE frequency points that can be measured for agreement, due to each terminal device manufacturer
The UE performances of production are different, and the frequency points that some UE can be measured are likely larger than the minimum value.In order to make full use of UE
Frequency point measurement capability, base station needs the maximum value for the frequency points for knowing that UE can be measured.
All there are a variety of working frequency range in the communication system of each standard, wherein and with frequency division duplex (Frequency
Division Duplexing, FDD) and time division duplex (Time Division Duplexing, TDD) divided, such as agreement
Defined in TS25.101 Universal Mobile Communication System (Universal Mobile Telecommunications System,

880MHz-915MHz and downlink 925MHz-960MHz) etc.；Being defined in agreement TS36.101 has frequency range 18 in the FDD of LTE
(uplink 815MHz-830MHz and downlink 860MHz-875MHz) etc. has frequency range 42 (3400MHz-3600MHz) in the TDD of LTE
Deng.The frequency point that can be measured that UE is reported should be fallen in some or all of frequency range as defined in agreement.In the embodiment of the present invention
In, base station receives the maximum value for the frequency points that the UE that UE is reported can be measured, while receiving the frequency point that the UE can be measured.
In subsequent step, the frequency point that base station can be measured according to above-mentioned maximum value and UE, from its preconfigured multiple frequency point really
The fixed UE needs the frequency point measured.The concrete configuration mistake of the maximum value of frequency point and the frequency points that can be measured that UE can be measured
Journey and process is reported to be described in detail in subsequent embodiment, details are not described herein.
Either any situation needs UE to carry out frequency point measurement, and base station is that other equipment is sent in receiving network
After information, frequency point is carried out to UE and measures control.After step slol, the base station receives presupposed information, the presupposed information
Determine that the UE needs the frequency points pair measured for triggering the base station.

The main body for sending presupposed information also can be different.When the signal quality for the serving cell that UE is received is deteriorated, sent to base station pre-
If the main body of information is UE, the presupposed information that UE is reported is event related to this.As an embodiment of the present invention, described
Base station receives the predeterminable event that the UE is reported, and the predeterminable event indicates the signal quality for the serving cell that the UE is received
Less than predetermined threshold value or the signal quality of the signal quality and the adjacent area received that indicate the serving cell that the UE is received
Difference reach predetermined threshold value.
UE can measure always the signal quality of its affiliated serving cell when being connect with serving cell, characterize the ginseng of signal quality
Number includes but not limited to Reference Signal Received Power (Reference Signal Receiving Power, RSRP) and reference letter
Number quality of reception (Reference Signal Receiving Quality, RSRQ) etc..When the signal quality is less than default threshold
When value, indicate that the serving cell preferably cannot provide service for the UE, the throughput of the UE it is relatively low or have a call drop can
Can, it needs to be switched in other cells, such case reporting base station is also referred to as reported A2 events, base station is according on UE by UE
The A2 events of report carry out frequency point to UE and measure control, are switched over finding suitable Target cell.
There are many kinds of being gone back due to the UE signal quality variations received and then the case where needing to report to base station, for example, UE
When the difference of the signal quality of the serving cell received and the signal quality of adjacent area is less than predetermined threshold value, UE reports A3 things to base station
Part, the A3 events that base station is reported according to UE carry out frequency point to UE and measure control, do not repeating one by one herein.
When UE carries out speech business, the main body that presupposed information is sent to base station is core net.As the another of the present invention
Embodiment, the base station receive the paging message that core net is sent.
Since LTE uses full packet switch (Packet Switch, PS) domain network structure, without tradition carrying voice industry
Domain circuit switching (Circuit Switch, CS) of business.When the UE under LTE network carries out speech business, it is necessary to find
The suitable second generation (the2nd Generation, 2G)/the third generation (the3rd Generation, 3G) network, by voice industry
Business is carried on the domains CS of the 2G/3G networks.For example, being based on circuit switching domain dropping (Circuit Switched in LTE
Fallback, CSFB) speech business solution, core net passes through mobile management after receiving the paging request of calling UE
Entity (Mobility Management Entity, MME) sends paging message to base station, and base station is receiving core net transmission
Paging message after to the called UE under it forward the paging message, and frequency point is carried out to UE and measures control, it is suitable to find
The 2G/3G network carryings called UEs speech business.
In step s 102, the base station determines the UE need according to the maximum value of the UE frequency points that can be measured
The frequency points to be measured, the UE need the frequency points measured to be less than or equal to the frequency points that the UE can be measured
Maximum value.
The frequency point of multiple adjacent areas can be configured in each base station, adjacent area can be with the base station with frequency homologous ray, alien frequencies
Situations such as homologous ray, different system.After base station receives presupposed information, determined according to the maximum value of the UE frequency points that can be measured
The UE needs the frequency points measured.
In embodiments of the present invention, after having received the A2 events that UE is reported or the paging message that core net is sent, base
Stand and read the maximum value of frequency points that UE can be measured, and combine the frequency point of multiple adjacent areas of itself configuration, take it is therein most
The frequency points that small value needs to measure as UE.For example, the maximum value for the frequency points that UE can be measured is 10, if in base station
The adjacent area frequency point of configuration is 5, then it is 5 that UE, which needs the frequency points measured,；If the adjacent area frequency point configured in base station is 20,
It is 10 that then UE, which needs the frequency points measured,.Determine that UE needs the method for the frequency points measured to be not specifically limited herein.
In step s 103, the base station needs the frequency that the frequency points measured and the UE can measure according to the UE
Point determines that the UE needs the frequency point measured.
After being determined that UE needs the frequency points measured, the frequency for needing to measure is selected from the adjacent area frequency point that base station configures
Point.The process of selection is specially：By the adjacent area frequency point configured in base station by rule compositor, the rule of sequence is voluntarily determined by base station
It is fixed, can arrange from high to low according to the priority of adjacent area, once cut the number of the adjacent area according to UE from more to arranging less
Deng.If what base station received is the A2 events that UE is reported, base station selects several adjacent areas of front frequency from the adjacent area frequency point arranged
The frequency point that point needs to measure as the UE；If what base station received is the paging message that core net is sent, base station is from the neighbour arranged
The frequency point of several 2G/3G networks of front, frequency points is selected to be determined by above-mentioned steps in area's frequency point.If the neighbour of 2G/3G networks
The number that area's frequency point deficiency above-mentioned steps determine then needs the frequency measured using the adjacent area frequency point of whole 2G/3G networks as the UE
Point.
The adjacent area frequency point that above step is selected must be fallen in the limit of power that UE frequency points measure.Base station determines that UE needs to survey
The method for the frequency points that the frequency point and needs of amount measure can also be there are many situation, and this is no longer going to repeat them.
Base station is using the maximum value of the UE frequency points that can be measured as the parameter for determining that UE needs the frequency points measured
One of, make to determine obtained final result compared with prior art, frequency points are more, while will not exceed the measurement energy of UE
Power, to take full advantage of the measurement capability of UE.
In step S104, the base station issues the UE and needs the frequency point measured.
