Specific embodiment

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 carried out clear, complete Site preparation is described, it is clear that described embodiment is only a part of embodiment of the invention, rather than whole embodiments.It is based on Embodiment in the present invention, it is every other that those of ordinary skill in the art are obtained under the premise of creative work is not made Embodiment, belongs to the scope of protection of the invention.

The embodiment of the present invention provides a kind of band measurement method, is applied to a kind of communication system, and the communication system includes： Two or more supports that the cell of narrow band communication, each cell include the different arrowband of at least two frequencies, the band of the arrowband Width less than or equal to the communication system system bandwidth, for example, in LTE system, the bandwidth of the arrowband can be 5M, 10M, 15M and 20M, as shown in figure 1, methods described is specifically included：

S101, terminal device are measured to the service quality of the arrowband of current area and/or the arrowband of other cells.

It should be noted that the current area is the cell residing for the current arrowband that terminal device is stopped, it is described current The arrowband of cell includes all arrowbands in current area, and described other cells are outside the current area residing for terminal device Support the cell of narrow band communication.Above-mentioned service quality is referred to as channel quality condition, can specifically include：RSRP (Reference Signal Receiving Power, Reference Signal Received Power) and RSRQ (Reference Signal Receiving Quality, Reference Signal Received Quality).Particularly, the measurement to the service quality of current arrowband can be held Continue what is carried out, i.e., no matter the terminal device all always carries out the service quality of current arrowband for Idle state or connected state Measurement.

S102, terminal device are analyzed to measurement result.

Terminal device can be directed to itself state in which, such as Idle state or connected state, narrow bandwidth range of measurement etc., to not Measurement result in the case of is made a concrete analysis of.

If S103, the measurement result meet default arrowband conversion condition, by the terminal device from described current narrow Band is transformed in the current area or described other cells on corresponding arrowband.

According to different situations, above-mentioned default arrowband conversion condition can have various, example, and above-mentioned arrowband converts bar Part can include terminal device in Idle state or connected state, current area internal pinch band gravity treatment or switching condition and minizone it is narrow Band gravity treatment or switching condition.Particularly, in embodiments of the present invention, described other cells are the current area residing for terminal device Outside support narrow band communication cell.

So, terminal device is operated in the network system for supporting narrow band communication, the narrower bandwidth of its work, terminal Equipment needs the situation for switching arrowband to go out according to the analysis of the measurement result to service quality in deep frequency selective decline etc. Now, the conversion of current area inside or minizone arrowband is selectively carried out, without the change for directly carrying out minizone of blindness Change, can so make the arrowband conversion of minizone more targeted, it is to avoid the useless conversion of minizone, so as to reduce resource wave Take；Meanwhile, the useful arrowband conversion in minizone or cell also causes that the terminal device after arrowband conversion obtains preferably clothes Business quality.

Further, before step S101, terminal device also needs to receive the measurement parameter that base station sends；And according to described Measurement parameter is configured to the terminal device.The measurement parameter can include：It is other arrowbands of current area with cell Measurement start-up parameter.Other arrowbands described in the embodiment of the present invention remove current arrowband in the current area residing for terminal device Outside arrowband.The measurement parameter can also include：The measurement start-up parameter of the arrowband of other cells, such as arrowband of co-frequency cell Measurement start-up parameter, and different frequency/different system cell narrow band detection start-up parameter.

It should be noted that above-mentioned measurement parameter may be referred to definition of the prior art, it is also possible to as the case may be Redefined, the present invention is without limitation.

It should be noted that because terminal device can have two kinds of working conditions：Idle state and connected state, in different operating State, the switching specific steps between switching and different districts of the terminal device between the arrowband of current area are not quite similar, because Here by taking Idle state and connected state as an example be described in detail respectively.

Example, when terminal device is in Idle state, the arrowband is transformed to arrowband gravity treatment, as shown in Fig. 2 the frequency Band measuring method includes：

S201, terminal device receive the measurement parameter that base station sends.

The measurement parameter can include the measurement start-up parameter of other arrowbands of current area, specially：First RSRP thresholds The measurement start-up parameter of value and/or the 2nd RSRP threshold values, and RSRQ threshold values, and other cell arrowbands, specially：3rd Whether RSRP threshold values and/or the 4th RSRP threshold values, and the 2nd RSRQ threshold values, need to carry out other arrowbands of current area for defining Measurement or other cell arrowbands measurement.Above-mentioned parameter is base station corresponding configuration, example, and base station can only configure One RSRP threshold values and a RSRQ threshold values, it is also possible to while configuring a RSRP threshold values, the 2nd RSRP threshold values and a RSRQ thresholds Value, but in the presence of the 2nd RSRP threshold values, a RSRP threshold values fail upon execution, i.e. terminal device with the 2nd RSRP threshold values and First RSRQ threshold values perform specific steps for reference threshold.Particularly, a RSRP threshold values and/or the 2nd RSRP threshold values, and First RSRQ threshold values can measure start-up parameter S-IntraSearch and/or S- with co-frequency cell of the prior art IntraSearchP is identical with S-IntraSearchQ.Similarly, base station can only configure the 3rd RSRP threshold values and the 2nd RSRQ thresholds Value, it is also possible to while the 3rd RSRP threshold values, the 4th RSRP threshold values and the 2nd RSRQ threshold values are configured, but when the 2nd RSRP threshold values are present When, a RSRP threshold values fail upon execution, i.e., terminal device with the 3rd RSRP threshold values and the 2nd RSRQ threshold values be reference threshold To perform specific steps.Particularly, the 3rd RSRP threshold values and/or the 4th RSRP threshold values, and the 2nd RSRQ threshold values can with it is existing The measurement of non-co-frequency cell start-up parameter S-NonIntraSearch and/or S-NonIntraSearchP in technology, and S- NonIntraSearchQ is identical.

The measurement parameter can also include simultaneously：The gravity treatment lagged value of current arrowband and the reselection offset value of other arrowbands, The gravity treatment between arrowband is carried out according to above-mentioned parameter in order to terminal device.

The measurement parameter can also include：Reselection time section, the reselection time for indicating different narrow band；Stop threshold value, For the crash time that instruction terminal equipment is stopped on an arrowband.

S202, terminal device are configured according to measurement parameter to terminal device.

S203, terminal device obtain the narrow band information of other cells.

The method that terminal device obtains the narrow band information of other cells can have various, example, and terminal device can lead to The broadcast for crossing current area own base station obtains the narrow band information of other cells.PSS (Primary Sync can also be obtained Signal, primary synchronization signal) and other cells for carrying of SSS (Secondary Sync Signal, secondary synchronization signal) Narrow band information, wherein it is possible to be that a PSS and SSS combinations carry a narrow band information, or multiple PSS and SSS combinations Carry same narrow band information.Terminal device can also be by obtaining Physical Cell Identifier PCI (Physical Cell Identifier, Physical Cell Identifier) come obtain PCI carrying other cells narrow band information.

S204, terminal device are measured to the service quality of the arrowband of current area and/or other cells.

The arrowband of the current area includes current arrowband and other arrowbands.Terminal device is to the current arrowband residing for itself The measurement of service quality persistently carry out.And the measurement of other narrowband service qualities is needed to meet current area other The measurement entry condition of arrowband, similarly, the measurement to other cell arrowbands is also required to meet the measurement startup of other cell arrowbands Condition.

When the measurement parameter of the base station configuration that terminal device is received includes a RSRP threshold values and a RSRQ threshold values, If the RSRP measured values of current arrowband are more than a RSRP threshold values, and the RSRQ measured values of current arrowband are more than described first RSRQ threshold values, terminal device can select the service quality not to other arrowbands to measure；Otherwise, terminal device tackles other The service quality of arrowband is measured, and described other arrowbands are except described current narrow in current area residing for the terminal device Arrowband outside band.

When the measurement parameter of the base station configuration that terminal device is received includes the 2nd RSRP threshold values and a RSRQ threshold values, If the RSRP measured values of current arrowband are more than the 2nd RSRP threshold values, and the RSRQ measured values of current arrowband are more than described first RSRQ threshold values, terminal device can select the service quality not to other arrowbands to measure；Otherwise, terminal device reply is described The service quality of other arrowbands is measured, and described other arrowbands are to work as except described in current area residing for the terminal device Arrowband outside preceding arrowband.

As can be seen that terminal device is when service quality reaches the measurement entry condition of other arrowbands, while work as The qos measurement of preceding arrowband and other arrowbands.

When the measurement parameter of the base station configuration that terminal device is received includes the 3rd RSRP threshold values and the 2nd RSRQ threshold values, If the RSRP measured values of current arrowband are more than or equal to the 3rd RSRP threshold values, and the RSRQ measured values of current arrowband are more than or equal to The 2nd RSRQ threshold values, terminal device can be measured to the service quality of other cell arrowbands；Otherwise, terminal The service quality of equipment reply other cell arrowbands is measured.Described other cells are have phase compared with current area The co-frequency cell of same priority or lower priority, or the different system with lower priority is small compared with current area Area.

When the measurement parameter of the base station configuration that terminal device is received includes the 4th RSRP threshold values and the 2nd RSRQ threshold values, If the RSRP measured values of current arrowband are more than or equal to the 4th RSRP threshold values, and the RSRQ measured values of current arrowband are more than or equal to The 2nd RSRQ threshold values, terminal device can be measured to the service quality of other cell arrowbands；Otherwise, terminal sets The service quality of standby reply other cell arrowbands is measured.Described other cells are with identical compared with current area The co-frequency cell of priority or lower priority, or the different system cell with lower priority compared with current area.

It should be noted that the narrow band detection of other cells with higher priority starts method compared with current area Prior art is referred to, the present invention is not limited.

Particularly, the 3rd RSRP threshold values and/or the 4th RSRP threshold values, and the 2nd RSRQ threshold values can be with prior art In non-co-frequency cell measurement start-up parameter S-NonIntraSearch and/or S-NonIntraSearchP, and S- NonIntraSearchQ is identical.The 3rd RSRP threshold values can be less than or equal to a RSRP threshold values, the 4th RSRP Threshold value can be less than or equal to the 2nd RSRP threshold values, and the 2nd RSRQ threshold values can be less than or equal to a RSRQ thresholds Value, when the 3rd RSRP threshold values are equal to a RSRP threshold values or the 4th RSRP threshold values equal to the 2nd RSRP thresholds Value, when the 2nd RSRQ threshold values are equal to a RSRQ threshold values, in order to reduce because of the cell that depth-selectiveness decline causes Between arrowband probability, can preferentially carry out the qos measurement of other arrowbands in current area.

S205, terminal device are analyzed to measurement result.

After the measurement of other arrowbands in completing current area, terminal device is analyzed measurement result as follows：

The RSRP virtual values of current arrowband are ranked up with the RSRP virtual values of other arrowbands；If in the reselection time In section, before at least there is the RSRP virtual values of the RSRP virtual values in the current arrowband of other arrowbands described in, and The terminal device is more than the stop threshold value in the current arrowband residence time, then judge to reach in the current area Portion arrowband reselection conditions, the reselection conditions are one of default arrowband conversion condition.Particularly, the stop threshold value can be 1 second.

The RSRP virtual values of above-mentioned current arrowband are the gravity treatment lagged value of the RSRP measured values with current arrowband of current arrowband Sum, the RSRP virtual values of other arrowbands are the difference of the reselection offset value of the RSRP measured values and other arrowbands of other arrowbands.On The gravity treatment lagged value for stating current arrowband can be with default or zero setting, when the gravity treatment lagged value of the current arrowband is set greater than 0 Numerical value when, represent the priority level of current arrowband in sequence, the numerical value is bigger, and priority is bigger.Above-mentioned other arrowbands Reselection offset value can be with default or zero setting, when the reselection offset value of other arrowbands is set greater than 0 numerical value, table Show priority level of other arrowbands in sequence, but, numerical value is bigger, and priority is smaller.Particularly, other arrowbands Reselection offset value can be that each arrowband in other arrowbands of correspondence sets a numerical value, or to owning in other arrowbands Arrowband unification sets a numerical value.For simplicity, the reselection offset value of other unified arrowbands is generally set.

Example, if the gravity treatment lagged value of current arrowband is 5, the reselection offset primary system one of other arrowbands is set to 3, currently The RSRP measured values of arrowband are 6, and the RSRP measured values of the arrowband S in other arrowbands are 4, then the RSRP virtual values of current arrowband It is 6+5=11, the RSRP virtual values of arrowband S are 4-3=1, if then according to rule compositor from big to small, the RSRP of current arrowband Virtual value is come before the RSRP virtual values of arrowband S.Particularly, the unit in above-mentioned calculating can refer to prior art, this implementation It is not added with example.

When the maximum arrowband of RSRP virtual values in the ranking results is one, the RSRP virtual values maximum is selected Arrowband is used as treating gravity treatment arrowband；When there is two or more the maximum arrowband of RSRP virtual values in the ranking results, selection is described The frequency phase-difference of frequency in the maximum arrowband of RSRP virtual values and current arrowband arrowband farther out is used as treating gravity treatment arrowband. Due to the long-term stop on single arrowband of terminal device it is possible that the frequency selective fading of depth is to decline deeply, and current In the case of arrowband frequency of occurrences Selective intensity, on the arrowband that frequency differs farther out with current arrowband, it is general that appearance declines deeply Rate is relatively low, therefore can select frequency phase-difference arrowband farther out as treating gravity treatment arrowband.

After the measurement for completing other cell arrowbands, terminal device is analyzed measurement result as follows：

When described other cells are alien frequencies or different system cell higher than the priority of the current area or relatively low When, according to the cell reselection parameters, judge whether the service quality of other cells meets the cell re-selection conditions.

Example, when other cells are smaller compared with high or relatively low alien frequencies or different system than the priority of the current area Qu Shi, if cell K is the arbitrary cells in other cells, arrowband n is the Arbitrary Narrow band in cell K, and cell reselection parameters are full Foot：

Srxlev=F (Srxlev n)；

Squal=F (Squal n)；

Wherein, Srxlev n=Q_{rxlevmeas n}-(Q_rxlevmin+Q_{rxlevminoffset})-P_compensation；

Squal n=Q_{qualmeas n}-(Q_qualmin+Q_{qualminoffset})。

Or meet：

Q_rxlevmeas=F (Q_{rxlevmeas n})；

Q_qualmeas=F (Q_{qualmeas n})；

Srxlev=Q_rxlevmeas-(Q_rxlevmin+Q_{rxlevminoffset})-P_compensation；

Squal=Q_qualmeas-(Q_qualmin+Q_{qualminoffset})；

Srxlev is the RSRP reselecting parameters of cell K, and Squal is the RSRQ reselecting parameters of cell K, Q_{rxlevmeas n}It is arrowband The RSRP measured values of n, Q_{qualmeas n}It is the RSRQ measured values of arrowband n, Q_rxlevminIt is default minimal detectable powers of cell K etc. Level, Q_{rxlevminoffset}It is Q_rxlevminReselection offset value, P_compensationIt is max (P_EMAX-P_PowerClass), wherein, P_EMAXIt is end Maximum uplink transmission power of the end equipment in cell K, P_PowerClassIt is that the maximum radio frequency determined by the classification of terminal device is defeated Go out power, Q_qualminIt is the default minimum quality levels of cell K, Q_{qualminoffset}It is Q_qualminReselection offset value, F () represent The maximum or minimum value of parameter in bracket, or average are asked, F () can be defined as the case may be.

It is small when other cells are alien frequencies or different system cell higher than the priority of the current area or relatively low Region measurement starts and reselecting parameters are calculated using the above method, and the measurement and gravity treatment of cell are same as the prior art, here no longer Repeat.

When other cells are co-frequency cell or alien-frequency district with equal priority, obtain current area and other are small The parameters sortnig in area；According to parameters sortnig, current area and other cells are ranked up；According to ranking results, other are judged Whether the service quality of cell meets cell re-selection conditions.

Example, when other cells are co-frequency cell or alien-frequency district with equal priority, if cell M is with frequency Arbitrary cells in cell or the alien-frequency district with equal priority, cell S is current area, and arrowband x is appointing in cell M Meaning arrowband, arrowband i is the Arbitrary Narrow band in cell S, and parameters sortnig meets：

R_S=F (R_Si)；

R_M=F (R_{M x})；

Wherein, R_{S i}=Q_{Meas, S i}+Q_hyst；

R_{M x}=Q_{Meas, M x}+Q_offset；

Or meet：

Q_{Meas, S}=fn (Q_{Meas, Si})；

Q_{Meas, M}=fn (Q_{Meas, Mx})；

R_s=Q_{Meas, S}+Q_hyst；

R_M=Q_{Meas, M}+Q_offset；

R_SIt is the parameters sortnig of cell S, R_MIt is the parameters sortnig of cell M, Q_{Meas, S i}It is the RSRP measured values of arrowband i, Q_{Meas, M x}It is the RSRP measured values of arrowband x, Q_hysT is cell S gravity treatment lagged values, Q_offsetIt is the reselection offset value of cell M, F () The maximum or minimum value of parameter in bracket, or average are asked in expression.F () can be defined as the case may be.

When other cells are co-frequency cell or alien-frequency district with equal priority, cell reselection parameters are using above-mentioned Method is calculated, and the specific measurement of cell and reselection modes are same as the prior art, repeat no more here.

S206, by terminal device from current arrowband gravity treatment to current area or other cells on corresponding arrowband.

After terminal device is analyzed measurement result, if measurement result reaches the current area internal pinch band gravity treatment bar Part, the terminal device is treated on gravity treatment arrowband from the current arrowband gravity treatment to described.

Particularly, in the case where terminal device is in Idle state, when base station needs to carry out the paging of particular terminal device When, it is necessary to send beep-page message to all arrowbands in current area, can send simultaneously, it is also possible to sent out one by one according to certain order Send, the beep-page message is received in order to particular terminal device.

Particularly, by the terminal device from the current arrowband gravity treatment to it is described treat on gravity treatment arrowband before, terminal Equipment can also carry out information exchange with current area own base station, specifically include：Terminal device can be in TA (Tracking Area, tracing area) when updating, reselection request is generated, reselection request includes ranking results or treats the information of gravity treatment arrowband；So Afterwards, reselection request is sent to current area own base station, it is true to terminal device transmission gravity treatment in order to current area own base station Recognize information；Finally, the gravity treatment confirmation that current area own base station sends is received.Wherein, when reselection request includes that sequence is tied During fruit, gravity treatment confirmation treats gravity treatment arrowband including current area own base station according to what ranking results were selected, works as reselection request Including when the information of gravity treatment arrowband, gravity treatment confirmation includes that current area own base station treats the information of gravity treatment arrowband really Recognize information.So, although terminal device is in Idle state, but current area own base station can grasp terminal device narrow The distribution situation for taking, when base station needs to carry out the paging of particular terminal device, it is not necessary to all arrowbands in current area Transmission beep-page message, but the distribution situation according to the terminal device on arrowband, directly send paging to corresponding arrowband Message, so that specific terminal device receives the beep-page message on the arrowband.If certain terminal device is pre- in current area If updating its arrowband location information not over TA in the time, illustrate that the terminal device may not in current area own base station Compass of competency, therefore the current area own base station can delete the corresponding arrowband location information of the terminal device, in order to Carry out arrowband location information management.The Preset Time can be several TA update cycles, such as 5 or 6 TA update cycles.

After terminal device is analyzed measurement result, if measurement result reaches minizone arrowband reselection conditions, by institute Terminal device is stated from the current arrowband gravity treatment to the corresponding arrowband of other cells.Specific reselecting method may be referred to existing skill Art, the present invention is repeated no more.

It should be noted that the number of above-mentioned steps can accordingly be increased and decreased according to actual conditions, the order of step Can suitably adjust, the embodiment of the present invention is merely illustrative, any one skilled in the art takes off in the present invention In the technical scope of dew, change or replacement can be readily occurred in, should be all included within the scope of the present invention.

Example, as shown in figure 3, when terminal device is in connected state, the arrowband is transformed to arrowband switching, the frequency Band measuring method includes：
