Specific implementation mode
It should be noted that in the absence of conflict, the features in the embodiments and the embodiments of the present application can phase
Mutually combination.The present invention will be described in detail below with reference to the accompanying drawings and embodiments.
The present invention provides a kind of long term evolution frequency points to measure report method, and Fig. 1 is according to the ... of the embodiment of the present invention long-term
Evolution frequency point measures the flow chart one of report method, as shown in Figure 1, including following step S102 to step S104.
Step S102, the terminal in the commonly connected states of UMTS receive the frequency point letter of the LTE frequency point to be measured from RNC
Breath reports time value with maximum measurement, wherein it is that RNC is used for terminal distribution to be measured that maximum, which measures and reports time value,
LTE frequency point measures the maximum duration value reported, and opposite with the time needed for the single LTE frequency point to be measured of terminal measurement
It answers.
Step S104, terminal are reported in time value in maximum measurement and are surveyed to LTE frequency point to be measured according to frequency point information
Amount reports.
In the related technology, if the terminal is in commonly connected state for a long time, the idle opportunity for measuring descending pilot frequency has
Limit, causes any frequency point of LTE system be measured and be reported, in this way, being moved to LTE from UMTS system in the terminal
It can not ensure the reliable mobile of the terminal during system.In the embodiment of the present invention, the terminal in commonly connected state is most
Big measure reports interior measured to LTE frequency point to be measured of time value to report so that RNC remains to know the wireless matter of LTE frequency point
Information is measured, to ensure that reliable mobile of the terminal from UMTS system to LTE system.Above-mentioned terminal measures single to be measured
It time needed for LTE frequency point, the i.e. ability information of terminal, will be introduced later.
Whether terminal reports time value (to be denoted as Tmax_ to calculate by reporting delay timer more than maximum measurement
rept).Terminal opens after the frequency point information for receiving the LTE frequency point to be measured from RNC and maximum measurement report time value
It is dynamic that delay timer is reported to carry out timing.
Above-mentioned steps S104 includes：It is reported in time value in maximum measurement, terminal determines the reporting uplink letter that itself is triggered
Enable message；Terminal is during reporting uplink signaling message with the measurement result for reporting LTE frequency point to be measured on road.This is preferred real
It applies in example, if in above-mentioned commonly connected state measurement process, terminal triggers uplink signaling message by arbitrary reason, then terminal
Stop the measurement to LTE frequency point immediately, and recorded frequency point information is reported delay timing sequentially with RNC is offered on the road
Device stops timing.
Since under commonly connected state, terminal usually can not report the measurement result of LTE target frequency points (to generally have in time
Deng until when having uplink signaling, the roads Cai Sui report together), so network can not completely reliably may be using these
Through long-term expired measurement result information, made a decision for subsequent movement behavior.So in the present invention, if terminal never has quilt
Arbitrary reason triggers any upstream message, then terminal continues to measure LTE frequency point, passes through the possible uplink with road later
The frequency point information of signaling message report complete documentation.If before reporting delay timer Tmax_rept to overflow, terminal does not have also
Have through the uplink signaling message report with road, then terminal will be opened by force exclusively for reporting the upper of LTE frequency point measurement result
Row message.So above-mentioned steps S104 includes：Maximum measures and reports time value then, and terminal opens uplink signaling message, wherein
The uplink signaling message of unlatching is used to report the measurement result of LTE frequency point to be measured.In this way, reaching maximum measure reports time value
When, the uplink signaling message for the measurement result for being exclusively used in reporting LTE frequency point is opened, ensure that the measurement result of LTE frequency point reports
Real-time.
Above-mentioned network to there are many mobile-initiated reasons of terminal 3G to 4G systems, such as：Terminal present position owns
Adjacent 3G serving cell signal qualities are all very poor, it is necessary to be moved to 4G serving cells, could maintain the service connection of user；For
Commercial interest reason is as much as possible placed on certain business in 4G systems to network tendentiousness and services, and triggering terminal 3G to 4G
Movement；Since load congestion occur in 3G systems, in order to dissolve the congestion state in 3G systems, network is selectively some
The user of FACH states is moved to 4G, etc. from 3G.
For report measurement results, the present invention also provides a kind of preferred embodiments, i.e., according to measurement result to LTE frequencies
Point is ranked up, and specifically, above-mentioned steps S104 includes：Terminal is according to the measurement result of LTE frequency point to be measured by well to bad
Sequentially, LTE frequency point to be measured is ranked up；Maximum measure report time value then, terminal report sequence it is preceding one or
The measurement result of multiple LTE frequency points to be measured.In this way so that RNC selects LTE frequency point as the behaviour of target LTE frequency point to terminal
Make to execute more convenient.It should be noted that this measurement result can be the frequency point information of the LTE frequency point to be measured of sequence
And/or pilot signal strength in each LTE frequency point to be measured is maximum or top-quality LTE cells.
Preferably, in the case where terminal also receives maximum measuring time value (being denoted as Tmax_meas) from RNC,
Wherein, maximum measuring time value is maximum duration values for to be measured LTE frequency point measure of the RNC to terminal distribution,
And it is corresponding with the time needed for the single LTE frequency point to be measured of terminal measurement, above-mentioned steps S104 includes：Terminal decile when
Between each of LTE frequency point to be measured LTE frequency point to be measured is measured respectively according to frequency point information in length, wherein decile
Time span be that the number of maximum measuring time value divided by LTE frequency point to be measured is calculated；Terminal is on maximum measures
The measurement result of LTE frequency point to be measured is reported in the value that calls time.In this preferred embodiment, terminal configures down according to RNC
The sequence of the LTE frequency point to be measured of hair, is time span (Tmax_meas/N, the N of decile in each LTE frequency point to be measured
For the number of frequency point to be measured) synchronization and whole serving cells scanning survey, so as to avoid the sky of descending pilot frequency is measured
Idle machine is limited.It should be noted that in order to reduce complexity, maximum measuring time value (is denoted as Tmax_meas), and maximum survey
Amount reports time value (being denoted as Tmax_rept) that can also be merged into the same parameter, i.e. logical meaning is variant, but physical significance
Normalizing.It should be noted that other than above-mentioned decile maximum measuring time value, terminal can also use other time of measuring
Scheduling mode.
It should be noted that due to the difference of terminal capability, terminal may not necessarily be complete in Tmax_meas/N time spans
At the scanning survey of whole serving cells in single LTE frequency point.
For above-mentioned preferred embodiment, in order to make it easy to understand, being exemplified below：
Terminal is recorded in each Tmax_meas/N time spans, the pilot signal matter measured in each LTE frequency point
Measure the measured value of either intensity (RSRQ or RSRP) best that serving cell and its signal quality or intensity.Original note
Recording string A is【Frequency point 1 (PCI=100, value=30db), frequency point 2 (PCI=105, value=33db), 3 (PCI=of frequency point
155, value=26db) ..., frequency point N (PCI=325, value=27db)】Herein, PCI is the LTE services measured
The physical label of cell, value are pilot signal quality or the measured value of intensity.Then, terminal according to signal quality or
The size of intensity measurements, reorder above-mentioned block A from high to low, obtains block B and is【Frequency point 2 (PCI=105, value
=33db), frequency point 1 (PCI=100, value=30db), frequency point N (PCI=325, value=27db), 3 (PCI=of frequency point
155, value=26db) ...】.
If in addition, terminal can also record the pilot signal quality measured in each LTE frequency point or intensity is best
A serving cell and its signal quality either intensity value such as 2 or 3 are done, then each frequency point measurement result value is asked
With averagely, is carrying out sequence similar to the above, reporting.
Preferably, state variable can be utilized to indicate the current state of terminal.In the terminal in the commonly connected states of UMTS
Receive the frequency point information of the LTE frequency point to be measured from RNC and after maximum measurement reports time value, terminal will with it is to be measured
The corresponding state variable of LTE frequency point is set as TRUE, and TURE indicates that terminal just executes LTE frequency point in the commonly connected states of UMTS and surveys
Amount task；It reports to measure LTE frequency point to be measured according to frequency point information in time value in maximum measurement in terminal and reports it
Afterwards, terminal sets state variable to FALSE, and the terminal that FALSE indicates has exited the commonly connected states of UMTS and executed LTE frequency point measurement
Task.It should be noted that in addition to the trigger condition that above-mentioned LTE measurement results report, under the triggering of the following conditions, terminal
Set state variable to FALSE, such as：Cell update occurs, RRC state changes, above-mentioned maximum measuring time value time-out.
The present invention also provides a kind of long term evolution frequency points to measure report method (sides RNC), and Fig. 2 is implemented according to the present invention
The long term evolution frequency point of example measures the flowchart 2 of report method, as shown in Fig. 2, including following step S202 to step
S204。
Step S202, RNC receive the ability information from the terminal in the commonly connected states of UMTS, wherein ability information
It is used to indicate the time needed for the single LTE frequency point to be measured of terminal measurement.
Step S204, RNC send the frequency point information of LTE frequency point to be measured and maximum corresponding with ability information to terminal
Measurement reports time value, wherein maximum measure report time value be RNC to terminal distribution for LTE frequency point to be measured into
Row measures the maximum duration value reported.
In the related technology, RNC is not aware that the ability that terminal measures target LTE frequency point in the commonly connected states of UMTS.Fig. 2
Shown in embodiment, RNC receives the ability information for the terminal itself that terminal is reported to it, and RNC learns the ability letter of terminal
Breath could be that terminal measures the preparation sufficiently long time in the commonly connected states of UMTS to target LTE frequency point, to comprising enough
The measurement for target LTE frequency point it is idle, and do not influence cell reselection performance in terminal UMTS system, otherwise network can not obtain
Obtain the sufficient quality information of target LTE frequency point.
Wherein, aforementioned capabilities information refers specifically to terminal and measures institute to single LTE frequency point to be measured in commonly connected state
The time needed, it is presented as ability grade.It is exemplified below：Ability grade 1 indicates that terminal can be completed in 1s to single to be measured
The scanning survey of the synchronization of LTE frequency point and whole serving cells；Ability grade 2 indicates that terminal can be completed in 3s to single
The scanning survey of the synchronization of LTE frequency point to be measured and whole serving cells；Ability grade 3 indicates that terminal can be completed in 5s
The scanning survey of synchronization and whole serving cells to single LTE frequency point to be measured.Above-mentioned to be merely illustrative, specific value is big
It is small to be determined by related work group.
It should be noted that ability informations of the RNC according to terminal, can pass through broadcast control channel (Broadcast
Control Channel, referred to as BCCH) system message or dedicated control channel (Dedicated Control
Channel, referred to as DCCH) certain specific messages, the frequency point information and and ability of one or more LTE frequency points to be measured
Corresponding maximum measure of information reports time value, is sent to terminal.
After above-mentioned steps S204, the measurement result that RNC is reported according to terminal determines suitable one or more targets
LTE frequency point executes terminal from UMTS system to the migration of LTE system target LTE frequency point, and concrete operations are as follows：RNC receives end
Hold the measurement result of the LTE frequency point to be measured reported；RNC determines one or more according to measurement result in LTE frequency point to be measured
A LTE frequency point is as the target LTE frequency point in LTE system；RNC is by the target LTE frequency point in terminal transfer to LTE system.
The LTE frequency point measurement result that RNC is reported according to terminal can relatively reliable be learned around terminal present position
The rough idea of LTE frequency point serving cell signal.Then RNC selects one according to different scene demands from the frequency point reported
A or multiple frequency points are finally displaced into the target frequency point ranges of LTE system as terminal.Then reorientation flow can be utilized,
Terminal transfer to LTE system.Because of measuring process before, so RNC issues reorientation message：RRC Connection Releases
Cell " E-UTRA Target Info " in message (RRC Connection Release) can more accurately configure target
Frequency point is migrated, to which terminal can establish new 4G RRC in LTE target frequency points with the cost of shortest 3G RRC disconnectings
Connection and wireless traffic carrying.
It can be seen from the above, wanting to realize that system reliably moves terminal from 3G to 4G, it is necessary to terminal or network be made to have
The radio quality information of 4G serving cells in standby target LTE frequency point, and this aspect depends on terminal in FACH states to LTE system
Measurement capability, on the one hand depend on control of the network to above-mentioned measurement, the present invention exactly frequency point is realized in terms of the two
Measurement report.
The realization process of the embodiment of the present invention is described in detail below in conjunction with example.
Preferred embodiment one
Fig. 3 is the flow chart that report method is measured according to the long term evolution frequency point of the preferred embodiment of the present invention one, such as Fig. 3 institutes
Show, including following step S302 to step S310.
Step S302, terminal pass through common control channel (Common Control Channel, referred to as CCCH) cell
New information Cell Update report it to support what commonly connected state measured target LTE frequency point to 3G network controller RNC
Ability indicates.Optionally, ability grade is designated as：Terminal can be completed within the 3s times to the same of single target LTE frequency point
The scanning survey of step and whole serving cells.
Step S304, RNC pass through the cell update confirmation message Cell of dedicated channel DCCH according to the ability of above-mentioned terminal
Update Confirm, 4 LTE frequency point information [F2, F3, F4, F5] to be measured and a maximum measuring time value Tmax_
Meas=120s (notes：Since terminal can not possibly continuously measure LTE target frequency points in FACH states, wherein one can only be utilized
The part measurement free time measures, so the Tmax_meas of RNC configurations should be the most short required time 3x4=12s of theoretical duty
Several integral multiples, 10 times of value here) and a maximum report delay time value Tmax_rept=240s to be sent to terminal.
Internal corresponding state variable LTE_FACH_MEAS values are TRUE, indicate that terminal enters the commonly connected states of UMTS and executes LTE frequencies
Point measurement task.
Step S306, the report delay timer, timing to Tmax_rept=240s that terminal opens a reverse countdown are super
When.Terminal does decile according to the sequence of the target LTE frequency point to be measured of RNC configuration distributings in each target LTE frequency point
The synchronization of Tmax_meas/N=30s time spans and scanning survey (pay attention to due to terminal capability and locally to measuring idle scheduling
The difference of mode, the scanning that terminal in 30s time spans, may not necessarily complete whole serving cells in single LTE frequency point are surveyed
Amount).Terminal is recorded in each 30s time spans, the pilot signal quality or intensity measured in each LTE frequency point
(RSRQ either RSRP) best that serving cell and its signal strength or quality measured values.Entire Tmax_meas=
In 120s time of measuring, terminal never triggers any upstream message by arbitrary reason, and terminal is completed to all LTE targets
The measurement of frequency point, obtaining original record string A is【F2 (PCI=100, value=30db), F3 (PCI=105, value=
33db), F4 (PCI=155, value=26db), F5 (PCI=325, value=27db)】Terminal according to signal strength or
The size of quality measured values, reorder above-mentioned block A from high to low, obtains block B and is【F3 (PCI=105, value=
33db), F2 (PCI=100, value=30db), F5 (PCI=325, value=27db), F4 (PCI=155, value=
26db)】.Internal corresponding state variable LTE_FACH_MEAS values are FALSE, indicate that terminal terminates the commonly connected states of UMTS
Execute LTE frequency point measurement task.
Step S308, before reporting delay timer Tmax_rept to overflow, terminal is not over any uplink with road
Signaling message report.When reporting delay timer timing to 240s, terminal is opened by force exclusively for reporting LTE frequency point to survey
Measure the out-hole run report message Measurement Report of result.Wherein the frequency point sequencing information in above-mentioned block B
Included in cell " Measured results on RACH ".
Step S310, RNC measure reported result according to terminal LTE target frequency points, can probably learn terminal present position
Serving cell signal quality in target the LTE frequency point F3, F2 of surrounding is preferable, and F5, F4 frequency point quality is taken second place.Since RNC needs
Terminal is moved to 4G systems from 3G based on service reason, therefore only selects that F3 is finally moved as terminal from the frequency point reported
