Below in conjunction with the accompanying drawing in the embodiment of the present invention, the technical scheme in the embodiment of the present invention is clearly and completely described, obviously, described embodiment is only the present invention's part embodiment, instead of whole embodiment.Based on the embodiment in the present invention, those of ordinary skill in the art, not making the every other embodiment obtaining under creative work prerequisite, belong to the scope of protection of the invention.
The applied system configuration of the embodiment of the present invention can be as shown in Figure 1, and this system configuration comprises Access Network functional module, core net functional module and user interface.Wherein, terminal (UE) can be according to predetermined period to Access Network functional module reporting measurement reports (Measurement Report, MR), this MR generally can comprise that terminal measures the information such as mark (for example cell ID, i.e. Cell ID) and the mark of other community of the signal level intensity of Ge community, each community useful signal accounting, main Serving cell.Access Network functional module reports MR core net functional module again, and core net functional module can be server or other network element device, for carrying out data statistics according to the MR reporting, and then definite interfered cell pair.User interface can provide the functions such as the customization output of warning, statistics for network operation optimization personnel.
For based on code division multiple access (Code Division Multiple Access, CDMA) communication system of technology, Access Network functional module can comprise radio network controller (Radio Network Controller, and all base stations (NodeB) of lower extension RNC), terminal is mutual with NodeB by eating dishes without rice or wine, the MR information of the terminal to report that NodeB collects, through RNC summarizing and reporting to core net functional module after, core net functional module can be carried out the right investigation in interfered cell based on the embodiment of the present invention.And for based on orthogonal frequency division multiplexer (Orthogonal Frequency Division Multiplexing, OFDM) Long Term Evolution (Long Term Evolution, LTE) technology, Access Network functional module can be evolved base station (eNodeB), for the MR information of the terminal to report collected and report core net functional module.
Embodiment mono-
The embodiment of the present invention provides a kind of mobile communication system to disturb arrange distinguish method, and as shown in Figure 2, the method comprises:
101, core net functional module is obtained the measurement report MR of terminal to report, and MR comprises the mark of main Serving cell and the signal strength information of main Serving cell, the mark of other community and the signal strength information of other community in each community that terminal measures.
Wherein, the core net functional module here can be server or other network element device.
Concrete, terminal can be periodically or the community that signal can be detected to it, aperiodicity ground measure, terminal can detect that the community of signal comprises main Serving cell and other community of terminal, then terminal forms MR by each cell measurement results detecting and reports Access Network functional module, in this MR, can comprise the mark of main Serving cell and the mark of other community of each community that terminal measures, and the signal strength information of main Serving cell and other community, the signal strength information here comprises reception signal absolute intensity, can be for example received signal code power (the Received Signal Code Power in cdma system, RSCP), also comprise the accounting of useful signal, it is for example signal interference ratio (Ec/Io), signal to noise ratio (Ec/No) etc.Like this, Access Network functional module is carried out summarizing and reporting to core net functional module by MR again.
It should be noted that, other community here is not defined as the adjacent area that main Serving cell configures, and can be understood as here in the middle of same MR, and other community here can be served as in the community, non-primary service area except main Serving cell.
102, core net functional module counts the total sampling number of MR at place, each main Serving cell according to the mark of main Serving cell, and the total sampling number of MR is the MR quantity that the MR quantity at place, main Serving cell or the signal strength information of main Serving cell are greater than the first predetermined threshold value.
Concrete, core net functional module is receiving after MR, can count according to the mark of main Serving cell in MR the total sampling number of MR of each community.The total sampling number of this MR can be the MR quantity at place during as main Serving cell, each community, the total MR sampled point quantity also can Shi Gai community occurring.As option, also can limit here while only having the signal strength information of main Serving cell to be greater than the first predetermined threshold value, this MR sampled point is just included statistics in, and namely statistics is effective MR sampling number of each community.
Exemplary, in the time obtaining effective sampling points, can preset first predetermined threshold value, such as selecting at least one in RSCP, Ec/Io, Ec/No as benchmark, for example limit in the time of the RSCP >=-105dBm of main Serving cell A in a MR sampled point, this MR sampled point is just calculated an effective sampling points, and the first predetermined threshold value is-105dBm.
Be understandable that, if adopt the first predetermined threshold value to obtain effective sampling points, follow-up for invalid covering sampling number or effectively cover the statistics of sampling number in this embodiment, be to add up by the effective MR after the first predetermined threshold value screening; If do not adopt the first predetermined threshold value, so follow-up statistics is added up as all MR of main Serving cell for each community.
For communication system or LTE coordinate multipoint (the Coordinated Multi-Point of CDMA technology, CoMP) system, main Serving cell can be to measure and control the leading community of waiting operation for terminal, simultaneously also for terminal provides business service.
103, core net functional module obtains that in same MR sampled point, other community is for the invalid covering sampling number of main Serving cell, and invalid covering sampling number is to judge obtained MR quantity according to the signal strength information of other community.
Concrete, obtaining after the effectively total sampling number of MR of each community as main Serving cell, can obtain in same MR sampled point other community for the invalid covering sampling number of main Serving cell.Its implementation can be: in same MR sampled point, if the signal strength signal intensity of other community fails the signal quality of terminal to produce grand diversity effect, and the signal strength information of described other community is greater than the second predetermined threshold value, determine that this MR sampled point is the invalid covering sampled point of other community for main Serving cell.
That is to say, the signal strength signal intensity of other community fail to the signal quality of terminal produce macro diversity effect and also signal strength signal intensity more intense be again two necessary conditions determining invalid covering sampled point.Specifically, for adopting the communication system of grand diversity technique, the signal strength signal intensity of determining other community fail to the signal quality of terminal produce grand diversity effect and signal strength signal intensity again more intense basis for estimation be: the signal strength information of other community is greater than the second predetermined threshold value, and the size of the predefined grand diversity of coupling system (Active Set) determines whether to produce macro diversity and is used for determining that whether MR is invalid covering sampled point; For not adopting the communication system of grand diversity technique, other community can not produce macro diversity effect, therefore, this condition of failing the signal quality of terminal to produce macro diversity effect is that all other communities acquiescences meet, and need to determine that so the more intense signal strength information that requires other community of signal strength information of other community is greater than the second predetermined threshold value.
Exemplary, at WCDMA mobile communication system (Wideband Code Division Multiple Access, etc. WCDMA) adopt in the 3G communication system of grand diversity technique, for having determined the MR sampled point that community A is main Serving cell, if the signal strength information of other community of another one B is greater than the second predetermined threshold value in same MR sampled point, and fail the signal quality of terminal to produce macro diversity effect, fail to play forward facilitation, this MR sampled point just can be used as the invalid covering sampled point of community B for this community A so.Specific implementation can be: while adding up invalid sampled point, can select at least one in RSCP, Ec/Io, Ec/No as benchmark, in same MR sampled point, if according to the parameter preset setting of the signal strength information of other community and community Active Set, other community may be in Active Set, determines that this MR sampled point is the invalid covering sampled point of other community for main Serving cell.
Wherein, grand diversity (Macrodiversity) refers to that travelling carriage keeps in touch with two or more base stations simultaneously, thereby strengthens received signal quality.
For instance, can enter Active Set about Yi Ge community with reference to 3G network or exit the parameter setting of Active Set, such as parameter preset in existing network arranges the main value with reference to Ec/Io, the embodiment of the present invention can select Ec/Io as calculating benchmark so.Thus, the invalid covering sampling number definition of community B can be divided into two kinds of situations, meet wherein a kind of: in (1) same MR sampled point, if the difference of the Ec/Io Zhi Biqiang community Ec/Io of community B (Ji Qiang community Ec/Io value deducts the Ec/Io value of community B) exceedes 6dB and is less than 12dB, the signal strength signal intensity that community B can be described is not very strong, not strong to producing macro diversity effect, namely, outside Active Set, this MR sampled point is the invalid covering sampled point of community B for community A; (2) in same MR sampled point, if the difference of the Ec/Io Zhi Biqiang community Ec/Io of community B is less than or equal to 6dB, but community B in this MR according to Ec/Io by by force to weak sequence precedence be greater than Active Set restriction (such as, the quantity of default Active Set small area is 3 to the maximum, and the intensity of community B is the 4th), the signal strength signal intensity that can know community B has been greater than the second predetermined threshold value, and judge that according to Active Set size community B is probably outside Active Set, therefore determined that GaiMRWei community B is for the invalid covering sampled point that is less than A.At this moment second predetermined threshold value is here not just a concrete threshold value, but the difference of the signal strength information of the signal strength information Yu Qiang community of community B and threshold value 6dB and 12dB are compared, so that the signal strength signal intensity size of community B to be described.
Above two kinds of situations, can judge that community B probably not in Active Set, also plays forward facilitation with regard to failing to the signal quality of terminal, and synchronous signal is more intense again, and the MR at B place, this community is just an invalid covering sampled point so.Here Qiang community can be the maximum community of Ec/Io value in this MR sampled point.The threshold value of Ec/Io is elected 6dB as, be mainly will with reference to Yi Ge community enter Active Set signal strength signal intensity (quality) requirement and disallowable go out the requirement of signal strength signal intensity (quality) of Active Set, the size of selected value need to guarantee that certain community can be retained in the bottom line of Active Set as far as possible.Here describing community B probably not in Active Set, is because Active Set has the speed of renewal problem, and namely community has to lag behind and enters the situation of activation.
Exemplary, at global system for mobile communications (Global System for Mobile Communications, the 2G communication system such as GSM), or in LTE communication system, do not adopt grand diversity technique, therefore, can know, for this system, whether the signal strength signal intensity that does not relate to other community produces the situation of macro diversity effect to the signal quality of terminal, the signal strength signal intensity that can be understood as other community fails the signal quality of terminal to produce macro diversity effect, therefore, in this communication system, when the signal quality information of community B has been greater than the second predetermined threshold value, namely the signal strength signal intensity of community B is stronger, main Serving cell A has been produced to negative effect, the MR sampled point that can determine community B and A place, community is invalid covering sampled point.Now, the signal strength signal intensity that can be understood as community B of the second predetermined threshold value is strong enough to than the difference of the signal strength signal intensity of this MR Zhong Qiang community lower than 12dB, the communication quality of community A has been produced compared with strong jamming, certain second predetermined threshold value here can be also other implementation, does not limit here.
For LTE-Advanced system, adopting on the basis of grand diversity technique, if other community is not the grand diversity community that service is provided for user, namely the signal strength signal intensity of other community fails the signal quality of terminal to produce macro diversity effect, and signal strength signal intensity is stronger again, be greater than the second predetermined threshold value, the MR sampled point that can determine other place, community is invalid covering sampled point.
104, core net functional module does invalid covering sampling number and the total sampling number of MR than obtaining invalid covering sampled point accounting.
105, core net functional module judges according to invalid covering sampled point accounting whether main Serving cell and other community are interfered cell pair.
Concrete, core net functional module is being added up each community when as main Serving cell, after the invalid covering sampling number of other community in same MR sampling for main Serving cell, invalid covering sampling number and the total sampling number of MR of this main Serving cell can be made to ratio, obtain invalid covering sampled point accounting.Then, invalid covering sampled point accounting and the 3rd predetermined threshold value can be compared, if invalid covering sampled point accounting is greater than the 3rd predetermined threshold value, determine that main Serving cell and other community are interfered cell pair.
According to above-mentioned giving an example, in the time that community B is greater than the 3rd predetermined threshold value for the invalid covering sampled point accounting of community A, illustrate that the signal of community B has produced more interference effect in the coverage of community A, community B and community A are interfered cell pair.This invalid covering sampled point accounting is higher, and interference effect is larger, and problem is more serious.This makes network maintenance staff accurately locate having carried out this interfered cell, realizes easily the interference investigation of the whole network aspect, and has saved resource.
For instance, the 3rd predetermined threshold value here can be set to 20%～30% etc., can be also other value, does not limit here.Certainly, also can not limit the 3rd predetermined threshold value, can be according to the descending Sequential output of invalid covering sampled point accounting to user interface, so that technical staff takes to disturb accordingly elimination work according to Output rusults.
The embodiment of the present invention provides a kind of mobile communication system to disturb the method for investigation, the method comprises: the measurement report MR that obtains terminal to report, MR comprises the mark of main Serving cell and the signal strength information of main Serving cell in each community that terminal measures, the mark of other community and the signal strength information of other community, count the total sampling number of MR at place, each main Serving cell according to MR, the total sampling number of MR is the MR quantity that the MR quantity at place, main Serving cell or the signal strength information of main Serving cell are greater than the first predetermined threshold value, obtain in same MR sampled point other community for the invalid covering sampling number of main Serving cell, invalid covering sampling number is to judge obtained MR quantity according to the signal strength information of other community, invalid covering sampling number and the total sampling number of MR are done than obtaining invalid covering sampled point accounting, and then judge according to invalid covering sampled point accounting whether main Serving cell and other community are interfered cell pair, can realize at network side so automatic collection and the statistics of data, in time determine interfered cell to and annoyance level, realize easily the interference investigation of the whole network aspect, and save resource.
Embodiment bis-
The embodiment of the present invention provides a kind of mobile communication system to disturb the method for investigation, be applied in the 3G systems such as WCDMA, on the basis of the step 101～step 104 providing at embodiment mono-, step 105 replaced with to following step 106～step 108, as shown in Figure 3, the method also comprises:
106, core net functional module obtains that in same MR sampled point, other community is for effective covering sampling number of main Serving cell, and effectively covering sampling number is to judge obtained MR quantity according to the signal strength information of main Serving cell.
Concrete, obtaining after the effectively total sampling number of MR of each community as main Serving cell, obtaining in same MR sampled point in the invalid covering sampling number of other community for main Serving cell, can obtain in same MR sampled point other community for effective covering sampling number of main Serving cell.Its implementation can be: in same MR sampled point, if the signal strength information of other community is greater than the second predetermined threshold value, and the signal strength signal intensity of other community can produce macro diversity effect to the signal quality of terminal, determine that MR sampled point is the effective covering sampled point of other community for main Serving cell.Because the 3G systems such as WCDMA itself have the namely concept of Active Set of grand diversity, be greater than the second predetermined threshold value and other community in the middle of Active Set so need to meet the signal strength information of other community, can determine that other community can play forward facilitation for main Serving cell, the MR at its place effectively covers sampled point.
Exemplary, in the 3G communication systems such as WCDMA, for having determined the MR sampled point that community A is main Serving cell, if the signal of other community of another one B is strong enough to the signal quality of terminal is played to forward facilitation in same MR sampled point, produced macro diversity effect, this MR sampled point just can be used as effective covering sampled point of community B for this community A so.Specific implementation can be: when statistics effectively covers sampled point, can select at least one in RSCP, Ec/Io, Ec/No as benchmark, in same MR sampled point, determine whether this MR sampled point is the effective covering sampled point of other community for main Serving cell.
For instance, can grid of reference enter Active Set about Yi Ge community or exit the parameter setting of Active Set, according to parameter preset in the existing network of above-mentioned explanation, the main value with reference to Ec/Io is set, select Ec/Io as calculating benchmark.Thus, effective covering sampling number definition of community B can be defined as: in same MR sampled point, if the difference of the Ec/Io Zhi Biqiang community Ec/Io of community B (Ji Qiang community Ec/Io value deducts the Ec/Io value of community B) is less than or equal to 6dB (if B Qia Weiqiang community, community, difference is just 0 so), and community B in this MR sampled point basis signal intensity (quality) by by force to weak sequence precedence do not exceed Active Set restriction (such as, default Active Set small area quantity is 3 to the maximum, and community B comes first 3), just can judge enough strong (or enough good) of signal of community B, probably join Active Set, thereby the signal quality of terminal is played to the facilitation of forward, so can determine that GaiMRWei community B is for the effective covering sampled point that is less than A, be that community B increases a counting for effective covering sampled point of community A.
Here Qiang community can be the maximum community of Ec/Io value in this MR sampled point.The threshold value of Ec/Io is elected 6dB as, be mainly will with reference to Yi Ge community enter Active Set signal strength signal intensity (quality) requirement and disallowable go out the requirement of signal strength signal intensity (quality) of Active Set, the size of selected value need to guarantee that certain community can be retained in the bottom line of Active Set as far as possible.Similar in the second predetermined threshold value and above-mentioned steps 103, it can not be a concrete threshold value, difference and the threshold value 6dB of the signal strength information (for example Ec/Io) of the signal strength information Yu Qiang community of other community are compared, so that the signal strength signal intensity size of other community to be described.Also can be other implementation, not limit here.
,, after the MR sampled point that You You community B occurs simultaneously travels through, just obtain Liao Yige community B for the invalid covering sampling number of community A and effectively cover sampling number as main Serving cell for all community A.
107, core net functional module will effectively cover sampling number and do than obtaining effective covering sampled point accounting with the total sampling number of MR.
For example effective covering sampled point accounting here total sampling number of MR divided by A place, community that can be just community B for effective covering sampling number of community A.
If 108 invalid covering sampled point accountings are greater than the 3rd predetermined threshold value, and effectively cover sampled point accounting and be less than the 4th predetermined threshold value, core net functional module determines that main Serving cell and other community are interfered cell pair.
Exemplary, if community B is higher for the accounting of the invalid covering sampled point of community A, be greater than the 3rd predetermined threshold value, simultaneously community B is relatively low for the accounting of effective covering sampled point that is less than A, be less than the 4th predetermined threshold value, the signal that community B can be described has so produced more interference effect in the coverage of community A, and community B and community A are severe jamming community pair.When two accounting othernesses larger, the problem of disturbing is so more serious, owing to having considered inevitably to cover overlapping situation in mobile communication system, to just more taking measures, process in time interference problem for the interfered cell that meets these two conditions simultaneously.
The 4th predetermined threshold value here for example can be set to 5%, also can, for other value, not limit here.Also can be according to the descending Sequential output of invalid covering sampled point accounting and the difference value that effectively covers sampled point accounting to user interface, so that technical staff carries out according to Output rusults the elimination work of disturbing.

110, core net functional module judges whether interference ratio is greater than the 5th predetermined threshold value, if interference ratio is greater than the 5th predetermined threshold value, determines that main Serving cell and other community are interfered cell pair.
If interference ratio has exceeded the 5th predetermined threshold value, the such community of the so above-mentioned community B giving an example and community A is to being just interference problem community urgently to be resolved hurrily.Interference ratio is larger, and problem is more serious.
The 5th predetermined threshold value here can be for example 3 or 4 etc., also can, for other value, not limit here.The MR data that can collect the whole network due to core net functional module, so calculate by traversal, the community that can obtain all regions that have overlapping covering between disturbance regime, again by additional user interface, can be for network maintenance staff exports statistics list, or alerting service is directly provided, such as according to community between the descending Sequential output of interference ratio, be convenient to technical staff for interfered cell to carrying out the work, saved human and material resources resource.
For the systems such as GSM, LTE R8, in same MR, if the signal strength signal intensity of other community is stronger, will cause interference to main Serving cell, therefore, can only need to calculate invalid covering sampled point accounting and determine interfered cell pair, not need further to calculate effectively covering sampled point accounting, and then unnecessary computations interference ratio.
