Embodiment
For making object, technical scheme and the advantage of the embodiment of the present invention clearer, below in conjunction with the accompanying drawing in the embodiment of the present invention, technical scheme in the embodiment of the present invention is clearly and completely described, obviously, described embodiment is the present invention's part embodiment, rather than whole embodiment.Embodiment based in the present invention, those of ordinary skills, not making the every other embodiment obtaining under creative work prerequisite, belong to the scope of protection of the invention.
The method flow diagram of user's migration in the high ferro communication network that Fig. 1 provides for the embodiment of the present invention one.As shown in Figure 1, the method for the present embodiment comprises:
Step 101, a plurality of velocity amplitudes that report within the speed judgement cycle according to base station and at least one pre-set velocity threshold value, obtain the speed state of user terminal;
In high ferro communication network, the radio network controller of network side (Radio Network Controller; Referred to as: RNC) can high ferro communication network be divided into different high ferro communication cells according to the circuit of high-speed railway, such as platform community, community along the line etc.Each high ferro communication cell and public network communication cell are similar, all by base station, are covered, and the user in high ferro communication cell communicates by base station and RNC.Wherein, base station can be periodically to the velocity amplitude of each user terminal under RNC reporting base station.For each user terminal, the movement velocity of this user terminal can be calculated in base station according to the signal strength signal intensity receiving, and wherein, frequency deviation estimates it is a kind of comparatively conventional mode of obtaining subscriber teminal speed, but is not limited to this.
At network side, RNC can pre-define one or more speed threshold values.While there is user in high ferro communication cell, RNC can be divided into different ranks by the speed of user terminal according to default speed threshold value, to identify the speed state of user terminal, such as identification user terminal, is low speed, high speed or middling speed etc.At the present embodiment, take a plurality of speed threshold values is example, and that user's speed state can be divided like this is thinner.For example: when the speed of user terminal is low speed lower than certain speed threshold value, higher than another speed threshold value, being at a high speed, is middling speed in the time of between two speed threshold values.
Step 102, according to the speed state of user terminal, obtain the mobile status of user terminal;
Wherein, according to user terminal, be low speed or high speed and middling speed etc., determine 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.
Step 103, according to the characteristic information of the mobile status of user terminal and high ferro communication cell, user terminal place, to user terminal, send and measure control message, so that user terminal is to specifying adjacent communication community to carry out 1G/2A affair and/or carry out adjacent area period measurement and reporting measurement result;
RNC is according to the characteristic information of the mobile status of user terminal and high ferro communication cell, place, by sending and measure control message to user terminal, carry out the measurement strategies of configure user terminal, make user terminal according to measuring control message to specifying the signal strength signal intensity of adjacent communication community to measure and reporting measurement result, so that RNC determines the destinations traffic community of user terminal according to the measurement result of user terminal to send up.Wherein, the characteristic information of high ferro communication cell, user terminal place mainly refers to the type of high ferro communication cell, and such as being platform community or community along the line etc., and RNC can directly obtain this characteristic information according to collocation strategy.
Step 104, according to the measurement result of user terminal to send up, user terminal is migrated to destinations traffic community.
RNC, according to the measurement result of user terminal to send up, after determining the destinations traffic community (being next communication cell) of user terminal, migrates to this destinations traffic community by user terminal.
Wherein, if user terminal is low speed user and for by being received as the public network user in high ferro communication network, the determined destinations traffic of RNC community is public network cell, by the migration operation high ferro private network community of this public network user terminal can being moved out; If being low speed in high ferro communication network or highspeed user or RNC, user terminal cannot determine that user terminal is the user of public network user or high ferro communication network, the destinations traffic community that RNC can determine this user terminal according to the actual moving direction of this user terminal or state, by user terminal being migrated to destinations traffic community, can guarantee this user terminal proper communication, and call drop not.
The method of user's migration in the high ferro communication network of the present embodiment, according to the velocity amplitude of user terminal, obtain motion state, according to motion state, obtain the mobile status of user terminal, then according to the type of the mobile status of user terminal and high ferro communication cell, place, to user terminal, send and measure control message to configure different measurement strategies to user terminal, and receive the measurement result that user terminal reports according to different measuring strategy, according to corresponding measurement result, determine the destinations traffic community that this user terminal is corresponding and this user terminal is moved, therefore, can guarantee on the basis of each user terminal proper communication, by the low speed user high ferro communication network of moving out, reduce the consumption of low speed user to resource in high ferro communication network, the service quality of raising to highspeed user.
In the 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 setting requires to go out Ambulatoria user by explicit recognition, for example, according to actual scene, can be set to 20～30Km/h (thousand ms/h), and conventionally Ambulatoria or the vehicle that enters platform region all can not exceed this speed.The middling speed threshold value that sets requires clearly to distinguish the train moving on the vehicle-mounted user of normal operation and low speed user and high-speed railway, for example according to actual scene, can be set to 120～150Km/h, conventionally the car speed on highway is 80～100Km/h, the highlyest can not surpass 150Km/h yet, therefore, the scope of above-mentioned middling speed threshold value is enough to distinguish the vehicle in all high speeds.The high-speed door limit value setting requires to distinguish the train moving on high-speed railway, and for example foundation actual scene can be set to 250～300Km/h, and on current high-speed railway, the speed of service of train is all within above-mentioned scope.The speed threshold value that the present embodiment sets is mainly to set in conjunction with current various vehicles and pedestrian's actual motion speed, wherein for high-speed door limit value, also can not limit, as long as all can be set as at a high speed higher than middling speed threshold value.
In addition, in order to improve the accuracy to the judgement of subscriber teminal speed state, RNC presets the speed judgement cycle, and this speed judgement cycle is a second level, and sets a plurality of speed report cycles that comprise base station, to obtain a plurality of velocity amplitudes of this user terminal.
Based on above-mentioned, the process that the present embodiment step 101 is obtained the speed state of user terminal is: RNC, within the speed judgement cycle, receives a plurality of velocity amplitudes of the user terminal that base station reports; Then, each velocity amplitude in the speed judgement cycle is all compared with at least one pre-set velocity threshold value, be about to each velocity amplitude and compare with slow door limit value and middling speed threshold value respectively.If a plurality of velocity amplitudes in the speed judgement cycle are all less than or equal to slow door limit value, user velocity is used lower than slow door limit value, determines that the speed state of interior user terminal of speed judgement cycle is lower-speed state; If a plurality of velocity amplitudes in the speed judgement cycle are all greater than middling speed threshold value, determine that the speed state of interior user terminal of speed judgement cycle is fast state, and identify this user terminal for highspeed user; If a plurality of velocity amplitudes in the speed judgement cycle are all greater than slow door limit value, and be less than or equal to middling speed threshold value, and the translational speed of determining user terminal according to the magnitude relationship of a plurality of velocity amplitudes not increases gradually or reduces gradually, maintain below middling speed threshold value, determine that the speed state of speed user terminal in the judgement cycle is for stablizing middling speed state; If a plurality of velocity amplitudes in the speed judgement cycle are all greater than slow door limit value, and be less than or equal to 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 determining interior user terminal of speed judgement cycle is astable middling speed state, and enters the next speed judgement cycle to continue the speed state of this user terminal of judgement.
Based on above-mentioned, a kind of execution mode of the present embodiment step 102 comprises:
Step 1021, RNC judge whether the speed state of user terminal is lower-speed state or stable middling speed state; If judgment result is that to be, perform step 1022; Otherwise, execution step 1023.
Wherein, for the ease of the mobile status of judgement user terminal, RNC presets measurement monitoring periods, judges the mobile status of user terminal to measure the speed state of user terminal in monitoring periods according to this.Wherein, the length of measuring monitoring periods can arrange according to actual needs flexibly, if for example need the result of determination of degree of precision, can setting measurement monitoring periods longer, otherwise, can setting measurement monitoring periods shorter.
If in measuring monitoring periods, the speed state of user terminal is always lower-speed state or stable middling speed state, illustrates that user terminal belongs to non-high speed and in stable condition user; Otherwise, illustrate that this user terminal belongs to the user of highspeed user or state labile.
Step 1022, RNC determine that user terminal is the first mobile status in the mobile status of measuring monitoring periods, and continue execution step 103;
Step 1023, RNC determine that user terminal is the second mobile status in the mobile status of measuring monitoring periods, and continue execution step 103.
Wherein, the user terminal in the first mobile status belongs in stable condition non-highspeed user, may be received into the public network user of high ferro communication network, may be also due to the low speed user under the high ferro communication network of railway operation characteristic generation; For such user terminal, the signal strength signal intensity of public network can meet its communication requirement conventionally, therefore, in conjunction with certain algorithm, can guarantee under the condition of user terminal proper communication, can consider such user terminal to move in public network.User terminal in the second mobile status may be the highspeed user in high ferro communication network, also may be because of the unstable user terminal that cannot be identified in high ferro communication network or in public network of mobile status, wherein in order to guarantee that user terminal can proper communication, the highspeed user that therefore, the user terminal of None-identified can be considered as in high ferro communication network treats.Based on this, for making the user terminal in the second mobile status can proper communication, such user terminal can only be stayed in high ferro communication network, therefore, to the migration strategy that such user terminal is corresponding, need to determine according to its actual moving direction.
Wherein, RNC setting measurement monitoring periods is a minute level, preferably at least comprises a normal talking duration, and normal talking duration is averaged and obtains a large amount of duration of calls by RNC.Based on this, in this measurement monitoring periods, will comprise a plurality of speed judgement cycles, for example comprise 3～4.Now, RNC can obtain continuously the speed state of user terminal in a plurality of speed judgement cycles before execution step 1021, and judged that whether the speed state of a plurality of interior user terminals of speed judgement cycle is identical.If judgment result is that identical, a plurality of speed in the judgement cycles speed state of user terminal identical, illustrate that the mobile status of user terminal is stablized, perform step 1021; Otherwise, if the speed state of a plurality of interior user terminals of speed judgement cycle is not identical, the mobile status that user terminal is described is unstable, therefore, can not blindly judge the mobile status of user terminal, need by the measurement of longer time, first speed judgement cycle that enters next measurement monitoring periods again monitors and judges the speed state of user terminal.Wherein, the speed state in each speed judgement cycle all can obtain referring to step 101.
In the present embodiment, by the speed state of user terminal in a plurality of speed judgement cycles is judged to accuracy and the reliability that can further improve result of determination.
Based on above-mentioned, a kind of execution mode of the present embodiment step 103 comprises:
The type of the mobile status of step 1031, RNC identification user terminal; When identifying the mobile status of user terminal and be the first mobile status, execution step 1032; Otherwise, execution step 1035.
Step 1032, RNC are according to the type of characteristic information judgement high ferro communication cell; Judge that high ferro communication cell is platform community or community along the line; If platform community, execution step 1033; Otherwise, execution step 1034.
Step 1033, RNC are sent and measure control message to user terminal by base station, so that user terminal carries out 1G/2A affair and carries out adjacent area period measurement reporting measurement result to measuring the adjacent public network communication cell of appointment in control message all adjacent communications community, then perform step 104;
Step 1034, RNC are sent and measure control message to user terminal by base station, so that user terminal carries out adjacent area period measurement reporting measurement result to measuring the adjacent public network communication cell of appointment in control message, then perform step 104;
Step 1035, RNC are sent and measure control message to user terminal by base station, so that user terminal carries out 1G/2A affair reporting measurement result to all adjacent communications community, then perform step 104.
Concrete, when user terminal is during in the first mobile status, explanation can consider this user terminal to migrate in public network.But because this user terminal may be public network user, also may be low speed user in high ferro communication network, for example: near or be positioned at high ferro communication cell and waiting for the user of train, again for example: in train departures or while entering the station with the user of train operation, therefore, can not directly this user terminal be judged to be to public network user and the high ferro communication network of being moved out, otherwise may cause occurring call drop or situation that cannot proper communication because of low speed user that high ferro operation characteristic produces.
Based on this, the present embodiment RNC further judges the type of high ferro communication cell according to the characteristic information of high ferro communication cell, user terminal place; If high ferro communication cell is platform community, think so this platform community and high ferro communication cell around (for example community along the line) and public network communication cell around adjacent area each other.Due to platform situation more complicated, RNC cannot 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 by measuring control message, corresponding measurement strategies and measuring object is handed down to user terminal.Now, measure in control message and carry adjacent area period measurement strategy and 1G/2A affair strategy simultaneously, and the measuring object that is respectively adjacent area period measurement strategy and the appointment of 1G/2A affair strategy, conventionally with community ID, represent different measuring object.Wherein, adjacent area period measurement strategy is the measurement strategies configuring while being public network user for user terminal, therefore, measurement control message is that the measuring object of this adjacent area period measurement strategy appointment is the public network communication cell adjacent with high ferro communication cell, user terminal place, require user terminal periodically to measure the signal strength signal intensity of adjacent public network communication cell, and the signal strength signal intensity of each adjacent public network communication cell that periodically reporting measurement arrives is to RNC.1G/2A affair strategy is the measurement strategies configuring while being the low speed user of high ferro communication network for user terminal, under this condition, require, according to the signal strength signal intensity on user terminal moving direction, user terminal is carried out to community switching or migration, therefore, RNC is that the measuring object of 1G/2A affair strategy appointment is all communication cells adjacent with high ferro communication cell, user terminal place (comprising high ferro communication cell and public network communication cell), and require the signal strength signal intensity of all adjacent communications of user terminal measurement community, and report the sign of this communication cell to RNC while requiring the large communication cell (i.e. the first communication cell) of the signal strength signal intensity of user terminal in high ferro communication cell, the current place of discovery signals strength ratio.For RNC, by according to the information receiving at first, determine the destinations traffic community of user terminal, the communication cell that user terminal should migrate to, performs step 104.If RNC first receives the measurement result that user terminal reports according to 1G/2A affair, according to this result, user terminal is moved; Otherwise, according to user terminal, carry out the measurement result that adjacent area period measurement reports user terminal moved.
If this high ferro communication cell is community along the line, and when around it, adjacent communication community comprises platform community and public network cell, in this case, can determine that the user terminal in the first mobile status belongs to the user outside railway line, be the public network user being received in high ferro communication network, now, RNC is this user terminal configuring adjacent cell period measurement strategy, and by measuring control message, corresponding measurement strategies and measuring object is handed down to user terminal.Now, measure and in control message, to carry adjacent area period measurement strategy and be the measuring object of this strategy appointment, and require the signal strength signal intensity of the adjacent public network of user terminal periodic measurement communication cell, and periodicity reports RNC, so that RNC determines the destinations traffic community of user terminal according to the measurement result reporting, perform step 104.
Wherein, when user terminal is during in the second mobile status, illustrate that this user terminal may be for having the highspeed user in the high ferro communication network identifying at a high speed, also may 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 high ferro communication network treats.Now, RNC configures 1G/2A affair strategy for such user, and by measuring 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 communications communities, and require the signal strength signal intensity of all adjacent communications of user terminal measurement community, and to RNC, report the sign of this first communication cell while finding that signal strength signal intensity is greater than the communication cell of the signal strength signal intensity of high ferro communication cell, current place (i.e. the first communication cell), so that RNC continues execution step 104.
Based on such scheme, a kind of execution mode of the present embodiment step 104 comprises:
Step 1041, RNC receive the measurement result that user terminal reports by base station, and judge the type of this measurement result; If measurement result is user terminal while carrying out the signal strength signal intensity of the adjacent public network communication cell that period measurement reports,, execution step 1042; If being user terminal, measurement result carries out the sign of the first communication cell that 1G/2A affair reports, execution step 1043.
Step 1042, RNC select communication cell that signal strength signal intensity is greater than default public network signal strength threshold value as destinations traffic community from adjacent public network communication cell, and user terminal is migrated to this destinations traffic community, 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, guaranteeing that user terminal move afterwards still can proper communication.
Step 1043, RNC will identify the first corresponding communication cell as destinations traffic community, and user terminal is migrated to this destinations traffic community, finish this migration operation.
The method of user's migration in the high ferro communication network of the present embodiment, according to the velocity amplitude of user terminal, determine the mobile status of user terminal, according to the type of the mobile status of user terminal and high ferro communication cell, place (being user terminal present position), to user terminal, send and measure control message with the measurement strategies of configure user terminal, the measurement result of returning according to user terminal is moved user terminal, the high ferro communication network of low speed user can being moved out, reduce the consumption of low speed user to high ferro communication network resource, reduced the impact on highspeed user; In addition, the present embodiment only, to the user terminal configuring adjacent cell period measurement strategy in the first mobile status, has reduced network configuration complexity, compares with the equal configuring adjacent cell of all user terminals period measurement strategy simultaneously, has reduced the transmission of space interface signaling; Moreover, the present embodiment is in the time cannot accurately judging user terminal in the first mobile status whether as public network user, be user terminal configuring adjacent cell period measurement strategy and 1G/2A affair strategy simultaneously, guaranteed that the low speed user causing due to train operation characteristic can stay high ferro communication network, guaranteed the continuity of its call.
