Embodiment
For the purpose, technical scheme and the advantage that make the embodiment of the invention clearer; To combine the accompanying drawing in the embodiment of the invention below; Technical scheme in the embodiment of the invention is carried out clear, intactly description; Obviously, described embodiment is the present invention's part embodiment, rather than whole embodiment.Based on the embodiment among the present invention, those of ordinary skills are not making the every other embodiment that is obtained under the creative work prerequisite, all belong to the scope of the present invention's protection.
The method flow diagram of user's migration in the high ferro communication network that Fig. 1 provides for the embodiment of the invention one.As shown in Figure 1, the method for present embodiment comprises:
In the high ferro communication network, the radio network controller of network side (Radio Network Controller; Abbreviate as: RNC) can the high ferro communication network be divided into different high ferro communication cells, for example platform sub-district, sub-district along the line etc. according to the circuit of high-speed railway.Each high ferro communication cell and public network communication cell are similar, are all covered by the base station, and promptly the user in the high ferro communication cell communicates through base station and RNC.Wherein, the periodically velocity amplitude of each user terminal under the RNC reporting base station is understood in the base station.For each user terminal, the base station can be calculated the movement velocity of this user terminal according to the signal strength signal intensity that receives, and wherein, frequency offset estimating is a kind of mode of obtaining subscriber teminal speed comparatively commonly used, but is not limited to this.
At network side, RNC can define one or more speed threshold values in advance.When having the user in the high ferro communication cell, RNC can be according to preset speed threshold value, and the speed of user terminal is divided into different ranks, with the speed state of identification user terminal, for example discerns user terminal and be low speed, still middling speed etc. at a high speed.Is example at present embodiment with a plurality of speed threshold values, like this can with user's speed state divide thinner.For example: being lower than the certain speed threshold value when the speed of user terminal is low speed, is higher than another speed threshold value at a high speed, is middling speed in the time of between two speed threshold values.
Wherein, be low speed or high speed and middling speed etc. according to user terminal, confirm user's mobile status.In the present embodiment, the mobile status of user terminal can be used for characterizing the movement tendency of user terminal, so that user terminal is correctly moved.
RNC is according to the mobile status of user terminal and the characteristic information of place high ferro communication cell; Through sending measurement control message to user terminal; Come the measurement strategies at configure user terminal; User terminal is measured and the reporting measurement result, so that RNC confirms the destinations traffic sub-district of user terminal according to the measurement result of user terminal to send up to the signal strength signal intensity of specifying the adjacent communication sub-district according to measurement control message.Wherein, the characteristic information of user terminal place high ferro communication cell mainly is meant the type of high ferro communication cell, for example be platform sub-district or sub-district along the line etc., and RNC can directly obtain this characteristic information according to collocation strategy.
RNC behind the destinations traffic sub-district (being next communication cell) of confirming user terminal, migrates to this destinations traffic sub-district with user terminal according to the measurement result of user terminal to send up.
Wherein, if user terminal is a low speed user and for by being received like the public network user in the high ferro communication network, then the determined destinations traffic of RNC sub-district is a public network cell, can be through migration operation with the high ferro private network sub-district of moving out, this public network user terminal; If being low speed or highspeed user or the RNC in the high ferro communication network, user terminal can't confirm that user terminal is the user of public network user or high ferro communication network; The RNC destinations traffic sub-district that can confirm this user terminal according to the actual moving direction or the state of this user terminal then; Can guarantee this user terminal proper communication through user terminal being migrated to the destinations traffic sub-district, and call drop not.
The method of user's migration in the high ferro communication network of present embodiment; Velocity amplitude according to user terminal obtains motion state; Obtain the mobile status of user terminal according to motion state, send measurement control message with to the different measurement strategies of user terminal configuration according to the type of the mobile status of user terminal and place high ferro communication cell to user terminal then, and receive the measurement result that user terminal reports according to the different measuring strategy; Confirm destinations traffic sub-district that this user terminal is corresponding and this user terminal is moved according to corresponding measurement result; Therefore, can guarantee on the basis of each user terminal proper communication, the low speed user high ferro communication network of moving out; Reduce the consumption of low speed user, improve service quality the highspeed user to resource in the high ferro communication network.
In present embodiment step 101, at least one speed threshold value that RNC sets comprises slow door limit value, middling speed threshold value and high-speed door limit value, but is not limited to this.Wherein, the slow door limit value that sets requires clearly to identify the Ambulatoria user, for example can be set to 20～30Km/h (km/hour) according to actual scene, and Ambulatoria or the vehicle that gets into the platform zone all can not exceed this speed usually.The middling speed threshold value that sets requires clearly to distinguish the train that moves on vehicle-mounted user and the low speed user and the high-speed railway of normal operation; For example can be set to 120～150Km/h according to actual scene; Usually the car speed on the highway is 80～100Km/h; The highlyest also can not surpass 150Km/h, therefore, the scope of above-mentioned middling speed threshold value is enough to distinguish all vehicles at a high speed.The high-speed door limit value that sets requires to distinguish the train that moves on the high-speed railway, and for example the foundation actual scene can be set to 250～300Km/h, and the speed of service of train is all within above-mentioned scope on the present high-speed railway.The speed threshold value that present embodiment sets mainly is to combine present various vehicles and pedestrian's actual motion speed to set, and wherein also can not do qualification for the high-speed door limit value, as long as be higher than all can being set at a high speed of middling speed threshold value.
In addition, in order to improve the accuracy that the subscriber teminal speed state is judged, RNC preestablishes the speed judgement cycle, and this speed judgement cycle is a second level, and sets a plurality of speed report cycles that comprise the base station, to obtain a plurality of velocity amplitudes of this user terminal.
Based on above-mentioned, the process that present embodiment step 101 is obtained the speed state of user terminal is: RNC receives a plurality of velocity amplitudes of the user terminal that the base station reports in the speed judgement cycle; Then, each velocity amplitude that speed was adjudicated in the cycle all compares with at least one pre-set velocity threshold value, is about to each velocity amplitude and compares with slow door limit value and middling speed threshold value respectively.If a plurality of velocity amplitudes of speed in the judgement cycle all are less than or equal to the slow door limit value, promptly user velocity is used and is lower than the slow door limit value, confirms that it is lower-speed state that speed is adjudicated the speed state of user terminal in the cycle; If a plurality of velocity amplitudes in the speed judgement cycle all greater than the middling speed threshold value, confirm speed in the judgement cycle speed state of user terminal be fast state, and identify this user terminal and be the highspeed user; If a plurality of velocity amplitudes of speed in the judgement cycle are all greater than the slow door limit value; And be less than or equal to the middling speed threshold value; And the translational speed of determining user terminal according to the magnitude relationship of a plurality of velocity amplitudes is not increase gradually or reduces gradually; Promptly maintain below the middling speed threshold value, the speed state of confirming speed user terminal in the judgement cycle is for stablizing the middling speed state; If a plurality of velocity amplitudes of speed in the judgement cycle are all greater than the slow door limit value; And be less than or equal to the middling speed threshold value; And the translational speed of determining user terminal according to the magnitude relationship of a plurality of velocity amplitudes is increasing gradually or is reducing gradually; The speed state of confirming interior user terminal of speed judgement cycle is astable middling speed state, and gets into the next speed judgement cycle to continue to judge the speed state of this user terminal.
Based on above-mentioned, a kind of execution mode of present embodiment step 102 comprises:
Whether the speed state at step 1021, RNC judges terminal is lower-speed state or stable middling speed state; If judged result is for being that then execution in step 1022; Otherwise, execution in step 1023.
Wherein, for the ease of the mobile status at judges terminal, RNC preestablishes the measurement monitoring periods, judges the mobile status of user terminal with the speed state of measuring user terminal in the monitoring periods according to this.Wherein, the length of measuring monitoring periods can be provided with according to actual needs flexibly, and the result of determination of degree of precision if desired for example is then can the setting measurement monitoring periods longer, otherwise, can the setting measurement monitoring periods shorter.
If in measuring monitoring periods, the speed state of user terminal is always lower-speed state or stablizes the middling speed state, explains that user terminal belongs to non-high speed and in stable condition user; Otherwise, explain that this user terminal belongs to the user of highspeed user or state labile.
Step 1022, RNC confirm that user terminal is first mobile status in the mobile status of measuring monitoring periods, and continue execution in step 103;
Step 1023, RNC confirm that user terminal is second mobile status in the mobile status of measuring monitoring periods, and continue execution in step 103.
Wherein, the user terminal that is in first mobile status belongs in stable condition non-highspeed user, possibly received the into public network user of high ferro communication network, also possibly be because the low speed user under the high ferro communication network that the railway operation characteristic produces; For such user terminal, the signal strength signal intensity of public network can satisfy its communication requirement usually, therefore,, under the condition that can guarantee the user terminal proper communication, can consider such user terminal is moved in the public network in conjunction with certain algorithm.The user terminal that is in second mobile status possibly be the highspeed user in the high ferro communication network; Also possibly be to be identified in the high ferro communication network or the user terminal in the public network because of mobile status is unstable; Wherein in order to guarantee that user terminal can proper communication; Therefore, can the highspeed user that the user terminal that can't discern is regarded as in the high ferro communication network be treated.Based on this, can proper communication for making the user terminal that is in second mobile status, such user terminal can only be stayed in the high ferro communication network, therefore, need decide according to its actual moving direction the migration strategy that such user terminal is corresponding.
Wherein, RNC setting measurement monitoring periods is a minute level, preferably comprises a normal talking duration at least, and the normal talking duration is averaged a large amount of duration of calls by RNC and obtains.Based on this, will comprise a plurality of speed judgement cycles in this measurement monitoring periods, for example comprise 3～4.At this moment, RNC can obtain the speed state of user terminal in a plurality of speed judgement cycles continuously before execution in step 1021, and judged whether the speed state of a plurality of interior user terminals of speed judgement cycle is identical.If judged result is identical, the speed state of promptly a plurality of interior user terminals of speed judgement cycle is identical, explains that the mobile status of user terminal is stable, and then execution in step 1021; Otherwise; If the speed state of a plurality of interior user terminals of speed judgement cycle is inequality; The mobile status that user terminal is described is unstable, therefore, can not blindly judge the mobile status of user terminal; Need the measurement through the longer time, i.e. next first speed judgement cycle of measuring monitoring periods of entering monitors the speed state of user terminal again and judges.Wherein, the speed state in each speed judgement cycle all can obtain referring to step 101.
In this execution mode, through the speed state of user terminal in a plurality of speed judgement cycles is judged the accuracy and the reliability that can further improve result of determination.
Based on above-mentioned, a kind of execution mode of present embodiment step 103 comprises:
The type of the mobile status of step 1031, RNC identification user terminal; When the mobile status that identifies user terminal is first mobile status, execution in step 1032; Otherwise, execution in step 1035.
Step 1032, RNC judge the type of high ferro communication cell according to characteristic information; Judge that promptly the high ferro communication cell is platform sub-district or sub-district along the line; If the platform sub-district, execution in step 1033; Otherwise, execution in step 1034.
Step 1033, RNC send measurement control message through the base station to user terminal; So that user terminal carries out the 1G/2A affair and the adjacent public network communication cell of appointment in the measurement control message is carried out adjacent area period measurement and reporting measurement result all adjacent communication sub-districts, execution in step 104 then;
Step 1034, RNC send measurement control message through the base station to user terminal, so that user terminal carries out adjacent area period measurement and reporting measurement result to the adjacent public network communication cell of appointment in the measurement control message, execution in step 104 then;
Step 1035, RNC send measurement control message through the base station to user terminal, so that user terminal carries out 1G/2A affair and reporting measurement result to all adjacent communication sub-districts, execution in step 104 then.
Concrete, when user terminal was in first mobile status, explanation can be considered this user terminal is migrated in the public network.But because this user terminal possibly be a public network user; It also possibly be low speed user in the high ferro communication network; For example: near or be positioned at the high ferro communication cell and waiting for the user of train, again for example: in the train departures or when entering the station with the user of train operation, therefore; Can not directly this user terminal be judged to be public network user and with its high ferro communication network of moving out, otherwise possibly cause call drop or situation that can't proper communication occurring because of low speed user that the high ferro operation characteristic produces.
Based on this, present embodiment RNC further judges the type of high ferro communication cell according to the characteristic information of user terminal place high ferro communication cell; If the high ferro communication cell is the platform sub-district, think this platform sub-district and on every side high ferro communication cell (sub-district for example along the line) and public network communication cell on every side adjacent area each other so.Because platform situation more complicated; RNC can't accurately judge the network classification under this user terminal really; Therefore; RNC is this user terminal configuring adjacent cell period measurement strategy and 1G/2A affair strategy simultaneously, and through measurement control message corresponding measurement strategies and measuring object is handed down to user terminal.At this moment, carry adjacent area period measurement strategy and 1G/2A affair strategy in the measurement control message simultaneously, and the measuring object that is respectively adjacent area period measurement strategy and the appointment of 1G/2A affair strategy, the different measuring object represented with sub-district ID usually.Wherein, Adjacent area period measurement strategy is the measurement strategies that disposes when being directed against user terminal for public network user; Therefore; Measurement control message be this adjacent area period measurement strategy appointment measuring object for and the adjacent public network communication cell of user terminal place high ferro communication cell, require the periodic signal strength signal intensity of measuring adjacent public network communication cell of user terminal, and the signal strength signal intensity of each adjacent public network communication cell of arriving of periodic reporting measurement is given RNC.1G/2A affair strategy is the measurement strategies that disposes when being the low speed user of high ferro communication network to user terminal; Requiring user terminal to be carried out sub-district switching or migration under this condition according to the signal strength signal intensity on the user terminal moving direction; Therefore; RNC is that the measuring object of 1G/2A affair strategy appointment is that all and user terminal belong to the adjacent communication cell (comprising high ferro communication cell and public network communication cell) of high ferro communication cell; And require the signal strength signal intensity of all adjacent communication sub-districts of user terminal measurement, and require user terminal reports this communication cell when the big communication cell (i.e. first communication cell) of the signal strength signal intensity of finding the current place of signal intensity ratio high ferro communication cell sign to RNC.As far as RNC, will confirm the destinations traffic sub-district of user terminal according to the information that receives at first, i.e. the user terminal communication cell that should migrate to, promptly execution in step 104.If RNC receives the measurement result that user terminal reports according to the 1G/2A affair earlier, then user terminal is moved according to this result; Otherwise, carry out the measurement result that the adjacent area period measurement reports according to user terminal user terminal moved.
If this high ferro communication cell is sub-district along the line; And when adjacent communication sub-district comprises platform sub-district and public network cell around it, in this case, can confirm that the user terminal that is in first mobile status belongs to the outer user of railway line; Be the public network user that is received in the high ferro communication network; At this moment, RNC is this user terminal configuring adjacent cell period measurement strategy, and through measurement control message corresponding measurement strategies and measuring object is handed down to user terminal.At this moment; Carry adjacent area period measurement strategy in the measurement control message and be the measuring object of this strategy appointment; And require the signal strength signal intensity of the adjacent public network communication cell of user terminal periodic measurement; And periodically report RNC, so that the measurement result that the RNC basis reports is confirmed the destinations traffic sub-district of user terminal, promptly execution in step 104.
Wherein, When user terminal is in second mobile status; Explain that this user terminal maybe be for having the highspeed user in the high ferro communication network that identifies at a high speed; Also possibly be speed-raising or reduction of speed both sign not at a high speed, also not be stable at middling speed and be equal to the user terminal that the highspeed user in the high ferro communication network treats.At this moment, RNC disposes 1G/2A affair strategy for such user, and through measurement control message corresponding measurement strategies and measuring object is handed down to user terminal.Under this condition; Measurement control message is included as the 1G/2A affair strategy of user terminal configuration and is the measuring object of this measurement strategies appointment; This measuring object is all adjacent communication sub-districts; And require the signal strength signal intensity of all adjacent communication sub-districts of user terminal measurement, and report the sign of this first communication cell when finding signal strength signal intensity to RNC greater than the communication cell (i.e. first communication cell) of the signal strength signal intensity of current place high ferro communication cell, so that RNC continuation execution in step 104.
Based on such scheme, a kind of execution mode of present embodiment step 104 comprises:
Step 1041, RNC receive the measurement result that user terminal reports through the base station, and judge the type of this measurement result; If measurement result is a user terminal when carrying out the signal strength signal intensity of the adjacent public network communication cell that period measurement reports,, execution in step 1042; If being user terminal, measurement result carries out the sign of first communication cell that the 1G/2A affair reports, execution in step 1043.
Step 1042, RNC from adjacent public network communication cell, select signal strength signal intensity greater than the communication cell of preset public network signal strength threshold value as the destinations traffic sub-district, and user terminal migrated to this destinations traffic sub-district, finish this migration operation;
Wherein, public network signal strength threshold value that RNC is pre-configured, as long as the signal strength signal intensity of public network cell is greater than this predetermined threshold value, can proper communication when user terminal migrates to this communication cell, guarantee that promptly user terminal still can proper communication after moving.
Step 1043, RNC will identify the first corresponding communication cell as the destinations traffic sub-district, and user terminal is migrated to this destinations traffic sub-district, finish this migration operation.
The method of user's migration in the high ferro communication network of present embodiment; Confirm the mobile status of user terminal according to the velocity amplitude of user terminal; Send the measurement strategies of measurement control message according to the mobile status of user terminal and the type (being the user terminal present position) of place high ferro communication cell to user terminal with the configure user terminal; Measurement result according to user terminal returns is moved user terminal; Can the low speed user high ferro communication network of moving out have been reduced the consumption of low speed user to the high ferro communication network resource, reduce influence the highspeed user; In addition, present embodiment only to being in the user terminal configuring adjacent cell period measurement strategy of first mobile status, has reduced the network configuration complexity, compares with the equal configuring adjacent cell period measurement of all user terminals strategy simultaneously, has reduced the transmission of space interface signaling; Moreover; Present embodiment is in the time can't judging accurately whether the user terminal that is in first mobile status is public network user; Be user terminal configuring adjacent cell period measurement strategy and 1G/2A affair strategy simultaneously; Guaranteed to have guaranteed the continuity of its conversation because the low speed user that the train operation characteristic causes can be stayed the high ferro communication network.
