Accompanying drawing explanation
Fig. 1 is the flow chart of the embodiment of the present invention 1;
Fig. 2 is the flow chart of the embodiment of the present invention 2.
Embodiment
Below in conjunction with accompanying drawing, the specific embodiment of the present invention is described.Abbreviation radio network controller is RNC, and user terminal is UE.
Embodiment 1
When UE is in the scene of high-speed motion, such as at high-speed railway, when highway moves, it often quickly move through a community.If according to prior art, the signal strength signal intensity of current area and neighbor cell is first measured by UE, then after finding that the signal strength signal intensity of current area is lower than certain value, send measurement report request to RNC again to switch, so may before RNC be also able to do in time judgement switching, UE has just shifted out former Serving cell, thus causes handoff failure and call drop.On the other hand, base station can have multiple method to measure the translational speed of UE in real time, utilizes this information can improve the timely of switching and accuracy to the handover realizing UE.
Namely be that a kind of NodeB measures the translational speed of UE with reference to what describe in figure 1, figure, and it is reported RNC, utilize this information to adjudicate the flow process of switching by RNC.
Step 101, RNC measures initial message by issuing one to NodeB, and the translational speed of order NodeB to UE is measured and measurement result reported to it.
Preferably, NodeB reports the measurement result of the translational speed of UE to RNC is report RNC by measurement result being placed in measurement report.
So-called initial message of measuring is one and is handed down to NodeB by RNC, requires that NodeB measures some measuring amount and provides the control message of report measurement results rule, and RNC can momentarily to NodeB sending measuring initial message.In the present invention, increase in the measurement initial message that RNC issues to base station and require that NodeB measures the translational speed of UE and requires that NodeB reports the indication information of the measurement result of UE translational speed to it.And report in process in measurement afterwards and measurement, RNC can send new measurement initial message to NodeB again to be stopped or restarting NodeB to the measurement of UE translational speed and the reporting schemes changing NodeB.
Preferably, NodeB reports the measurement result of UE translational speed can adopt one or several combination of following three kinds of modes to RNC:
Mode one: periodically reporting schemes
In measurement initial message, RNC gives a period of time T, and NodeB receives and measures after initial message, to send the measurement report of the translational speed of all UE measured by it, comprise the measurement result to this UE translational speed in measurement report with T for the cycle to RNC;
Mode two: trigger reporting schemes
In measurement initial message, RNC gives the threshold T h of a speed, when the translational speed that NodeB measures certain UE reaches threshold T h, NodeB reports the tachometric survey of this UE report (comprising the measurement result to this UE translational speed in measurement report) to RNC.
Mode three: RNC command report mode,
RNC momentarily carrys out by order requirement NodeB to report the translational speed of certain UE measurement result to it.
Step 102, base station measures the translational speed of UE in community that it covers in real time;
Preferably, NodeB measures all UE being in connection status in its coverage cell.So-called UE is in connection status, refer to that UE is in CELL-DCH state (dedicated channel, Dedicated Channel) or CELL-FACH state (forward access channel, Forward Access Channel), that is UE is on above-mentioned two channels and have connection between NodeB.
In this step, also NodeB can be specified to carry out the measurement of translational speed to which or which UE by RNC.
The method of the translational speed of the present invention's preferred base station measurement UE is as follows: the first Doppler frequency shift of base station measurement UE, the angle of arrival arriving antenna for base station from UE signal is also measured in base station simultaneously, then according to the anti-translational speed releasing UE of following Doppler shift formula:
Here namely V is the translational speed of UE, f
drepresent the values of Doppler frequency shift of UE, c is the light velocity (equaling 3*108m/s), and θ represents that UE signal arrives the angle of arrival of antenna for base station.
Step 103, if in a step 101, RNC regulation NodeB in Survey control message reports the mode of the measurement report of UE translational speed to be trigger to report to it, so NodeB judges the translational speed of UE, if the translational speed of certain UE reaches set speed threshold value Th, then perform step 104; Otherwise perform step 102;
If in a step 101, RNC regulation NodeB in Survey control message reports the mode of the measurement report of UE translational speed to be periodic report to it, so NodeB performs step 104 every period of time T, and the measurement report of all UE measured by it in RNC reporting subdistrict at step 104.
Only depicting RNC regulation NodeB in Survey control message at Fig. 1 reports the mode of the measurement report of UE translational speed to be trigger the steps flow chart reported in this case to it.
Step 104, base station reaches the measurement report of the UE of set speed threshold value to the translational speed that RNC reporting measurement obtains;
The measurement report of described UE comprises:
(1) identification number of this UE of unique identification, identification number can be the wireless link RL-id shared by this UE, or can be the DCH channel number DCH-id shared by it for the UE of CELL-DCH state.
NodeB and UE between set up wireless link time, can be the unique wireless link RL-id of each wireless link distribution one, therefore this wireless link number can represent the UE corresponding to this wireless link uniquely.
(2) velocity amplitude of this UE that records of NodeB, as the reference conditions that RNC judgement switches.
NodeB reports the translational speed of the UE obtained measured by it to RNC, can directly report this velocity amplitude.The UE translational speed such as measured is 30m/s, and so namely NodeB reports this value (30m/s).Or NodeB can report the grade point of UE translational speed, and grade point is made an appointment by RNC and NodeB.The speed of such as 0-30m/s is predefined as grade A, and the speed of 30-50m/s is predefined as grade B, and the speed of more than 50m/s is predefined as grade C, and the translational speed recording certain UE as NodeB is 70m/s, and so it reports the speed of this UE to be grade C to RNC.
Can also preferably include in measurement report:
(3) base station is by measuring other characterization value about this UE quality to received signal obtained.This UE that such as base station measures to signal interference ratio (Signal-to-Interference Ratio, the SIR) value of described Serving cell, received signal power (Received Signal Code Power, RSCP) value, and best cell etc.
Step 105, RNC receives measurement report, performs the switch decision to UE.
Whether RNC adjudicates this UE to new cell merge after receiving the UE tachometric survey report that base station reports.
Described new community refers to any one community in the neighbor lists of current service cell, UE place.Neighbor cell list is kept at RNC inside, and it includes the some communities adjacent geographically with a community, further comprises and a same geographic area of MPS process, but be in various level community for hierarchical network.In the wireless network of the high-speed railway of reality, highway, hierarchical network is more common situation, the UE near common along the line of the MPS process of public network, the UE that in private network MPS process compartment, high-speed motion.RNC, after the UE tachometric survey report receiving base station, performs cell merge and so also will indicate UE if adjudicate this UE and to which community switch.
Multiple implementation is had according to the UE translational speed measured by NodeB to adjudicate switching after the measurement report that RNC receives.Such as NodeB is reported periodically to the mode of UE translational speed, RNC can calculate the distance that this UE runs within this cycle by the translational speed reporting cycle T to be multiplied by UE, then accumulate the range ability of this UE of each time cycle; When the distance of accumulating has reached the border of this Serving cell, UE place, so adjudicate switching.Or, such as NodeB is triggered to the mode reporting UE translational speed, RNC can in conjunction with the UE received to the sir value of Serving cell to adjudicate switching: when RNC receives the measurement report of the UE translational speed reported (illustrating that the translational speed of this UE is greater than threshold value), as long as UE to the sir value of Serving cell lower than a higher threshold value SIR
high, namely RNC adjudicates switching; When RNC does not receive the measurement report of the UE translational speed reported (illustrating that the translational speed of this UE is lower), UE will lower than a lower threshold value SIR to the sir value of Serving cell
low, RNC adjudicates switching.
Embodiment 2
Adjudicate the accurate of UE switching and promptness for improving RNC further, NodeB adds the metrical information reporting UE Doppler frequency shift in the present embodiment.The Doppler frequency shift of UE is the frequency shift (FS) because UE Doppler effect at the volley produces.RNC, after the translational speed combining UE and Doppler frequency shift, is conducive to making switch decision more accurately.
Be below the concrete steps flow process of embodiment 2, the part identical with embodiment 1 is omitted.
Step 201, RNC measures initial message by issuing one to NodeB, and the translational speed of order NodeB to UE is measured and measurement result reported to it by measurement report.
Identical with embodiment one, RNC requires that NodeB report the measurement result of UE translational speed to it has two kinds of reporting schemes, namely periodically reports and triggering reports.Continue flow process with periodicity reporting schemes below to describe, in measurement initial message, RNC gives report cycle T.
In the present embodiment, RNC also requires that NodeB reports the Doppler frequency shift of UE requiring that NodeB reports outside the translational speed of UE.
RNC can carry out by measuring initial message the Doppler frequency shift that requirement NodeB reports UE, also can carry out requirement by alternate manner to report, NodeB is indicated as by the Survey control message on RACH (Random Access Channel, Random Access Channel) channel.
Step 202, NodeB measures translational speed and the Doppler frequency shift of UE in community that it covers in real time.
Between UE and NodeB when setting up wireless link, the frequency that one sends signal mutually can be arranged, UE sends signal with this frequency to NodeB, but due to the Doppler frequency shift impact produced in UE motion, there is deviation between the signal frequency of UE and the frequency of agreement in what result in that NodeB receives.NodeB can obtain this deviate by measurement, and estimates the values of Doppler frequency shift of UE further.
The method of NodeB measurement UE translational speed can be in the same manner as in Example 1.
Step 203, NodeB reports the measurement report comprising UE translational speed to RNC with period of time T.
In addition, NodeB also reports the Doppler frequency shift of this UE to RNC.NodeB reports the Doppler frequency shift of this UE to be reported by measurement report equally to RNC, and the Frame that also can pass through DCH (DedicatedChannel, dedicated channel) channel reports.
Identical with embodiment one, comprise in the measurement report that described NodeB reports to RNC:
(1) unique identification number indicating this UE;
(2) velocity amplitude of this UE that records of NodeB.The occurrence of the translational speed of the UE that NodeB can directly report it to survey, also can report the grade point of this translational speed.
Can also comprise
(3) values of Doppler frequency shift of this UE;
(4) base station by measure obtain other about this UE is to the characterization value of the received signal quality of Serving cell and/or neighbor cell.This UE that such as base station measures to the sir value of described Serving cell and/or neighbor cell, RSCP value, and best cell etc.
If NodeB does not report the Doppler frequency shift of UE by measurement report, so NodeB can also report with the Frame on DCH channel.Specifically, the field that it can increase a 16bit in the Frame on DCH channel represents the values of Doppler frequency shift of this UE.
Step 204, RNC receives measurement report, and the translational speed of the UE that foundation reports and values of Doppler frequency shift switch to adjudicate this UE.
The accuracy that translational speed according to UE improves switch decision is illustrated in embodiment one, and after facilitating the information of the values of Doppler frequency shift of UE, RNC can carry out switch decision more accurately.Due to when UE is away from base station, its values of Doppler frequency shift increases gradually; And along with the increase of distance, the speed that values of Doppler frequency shift increases also increase gradually.And base station is positioned at center of housing estate, also just mean the edge close to community away from base station, therefore RNC can improve according to the increase speed of UE values of Doppler frequency shift the probability that judgement UE performs switching.
Also need in addition to illustrate, RNC obtains the translational speed of UE except for except switching, can also have other purposes.Such as, RNC is multiplied by by the translational speed of the UE reported and reports interlude T to calculate this UE move distance during this period of time, and accumulation reports the displacement of period at every turn, and the position that just energy positioning UE is residing at present, assists for business such as location-based services.Again such as, in hierarchical network, RNC can according to the translational speed size of UE for this UE carries out network selection, and the UE that translational speed is large is chosen in the large macrocell of covering radius, and the UE that translational speed is little is chosen in the little Microcell of covering radius.
The above, be only preferred embodiment of the present invention, be not intended to limit protection scope of the present invention.
