UE can be realized in the following manner from first network to the second network switching: access network equipment sends switching request message to mobile management network element, and access network equipment receives response message of the mobile management net element based on switching request message feedback.Here, handoff request message includes the identification information of Target cell (i.e. the second network cell) or target BS (i.e. the second network base station) that UE will be switched to.Switching request message is used to trigger the switching that target network side (i.e. the second network) is UE and prepares corresponding resource.Access network equipment sends switching command after receiving response message, to UE, to indicate UE from first network to the second network switching.

UE can be realized in the following manner from first network to the second network redirection: access network equipment sends redirection information to UE, for triggering UE to the second network redirection.Specifically, redirection information may include being sent to UE by access network equipment in radio resource control RRC Connection Release (RRC connection release) message, and wherein redirection information includes target network (i.e. the second network) information such as frequency point and/or cell ID.

Generally, in order to improve the communication quality of private network user, the user for private network of moving out for some reason can be moved on private network again, and it is connected to the non-private network user on private network and moves to common public network, it can guarantee that private network user resides at private network and enjoys private network resource in this way, in addition guarantee that private network resource is not occupied by public network user, so as to improve the communication quality of private network user.

Below in conjunction with the specific implementation flow of the network migration method of the UE of specific example the present invention will be described in detail the embodiment of Fig. 3 to Fig. 5.Specifically, it can be illustrated by taking high-speed rail LTE private network and periphery LTE public network as an example.

Fig. 3 is the schematic flow chart of the network migration method of the UE of another embodiment of the present invention.It can be executed below by the eNB in common network in method shown in Fig. 3, i.e., access network device is the eNB in common network.

The historical information of 301, common network eNB acquisition UE.

Common network eNB can obtain the historical information of UE by the historical information of the UE sent of the upper eNB where receiving UE.The historical information of UE may include the identification information for the historical cell that UE was resident, and can also include the temporal information being resident in each historical cell.

Common network eNB can also configure the frequency point of high-speed rail private network, and using this frequency point as the frequency point of the high-speed rail UE target network returned.If subsequent UE uses switching or the redirection based on measurement from first network to the second network migration selection, public network eNB can be measured the signal parameter of the frequency point of configured high-speed rail private network, just to switch over or redirect according to measurement result.

302, common network eNB configure the information of common network cell near along high-speed rail.

The identification information of multiple common network cells along covering high-speed rail can be configured on common network eNB.For example, the identification information of all common network cells along covering high-speed rail can be configured on common network eNB.For another example, common network eNB can configure the eNB interior identification information for covering all common network cells along high-speed rail of prescribed limit nearby.

Step 302 is optional step, just needs to be implemented step 302 when also to continue by step 305 after step 303 in the embodiment of the present invention and further determine that whether UE is high-speed rail private network user, otherwise, can be directly entered step 303 by step 301.

303, common network eNB judge whether connected state UE switching frequency is greater than preset value.

Connected state UE refers to the UE of access eNB.The switching frequency of UE can be the frequency that UE switches between different community, be also possible to the frequency that UE switches between different eNB.

Switching frequency in the embodiment of the present invention can with UE in nearest given time period T after cell number or base station number indicate.Switching frequency can also be resident the time used in M cell of specified number or base station with UE to indicate recently.Switching frequency can also with UE recently after N number of cell in, how many (such as n, n≤N) cell meets UE and is less than t second in the residence time of each cell to indicate, at this point, n is bigger, expression switching frequency is faster.Above-mentioned N, T, n, t can be configured according to specific environment and strategy, and it is not limited in the embodiment of the present invention.

In one embodiment of the invention, common network eNB can obtain the identification information for the historical cell that UE was resident according to the historical information (history information) of UE and by the temporal information of each historical cell.For example, common network eNB can be obtained according to the historical information of UE UE after cell mark and residence time Jing Guo each cell.Common network eNB UE can be entered the cell ID of each cell and the beginning and ending time is recorded in the historical information of corresponding UE.When UE is switched to another target eNB from a common network eNB by X2 or S1 interface, eNB can be by the history information transmittance of UE to target eNB.Similarly, after the historical information for obtaining UE, target eNB can also add the cell information that UE is newly accessed in UE history message, for example, cell identity information under UE access target eNB, into the cell under target eNB time and switch out time of the cell under target eNB.In this way, each eNB that UE passes through can obtain the frequency that above-mentioned UE switches between different community by the historical information of acquisition UE.

In another embodiment of the present invention, common network eNB can also increase the resident base station information of UE in the historical information (history information) of UE.For example, common network eNB can be recorded in the historical information of UE by the UE base station identification information being resident and by the residence time of each base station.When UE switches between different eNB, UE can be by the history information transmittance of the UE To target eNB, target eNB can continue to add target eNB identification information and UE enter and time for cutting out to UE historical information.In this way, each eNB that UE passes through can obtain the frequency that above-mentioned UE switches between different eNB by the historical information of acquisition UE.

Optionally, step 303 can also judge whether the movement velocity of connected state UE is greater than threshold value to determine whether UE is high-speed rail private network user by common network eNB.For example, the movement velocity that common network eNB can calculate in the location information of different moments UE by recording UE in the historical information of UE.For another example, common network eNB can also calculate the movement velocity of UE using Doppler frequency shift algorithm.When upper or certain moment UE movement velocity is more than or equal to threshold value to UE along certain time or a certain section of high-speed rail, it is believed that the UE is high-speed rail private network user, which can be switched to high-speed rail private network or enter step 305 next judgement process.

304, if step 303 is judged as that switching frequency is less than or equal to preset value, common network eNB is without special operation.

When common network eNB judges to obtain UE switching frequency less than or equal to preset value in step 303, it is believed that UE is not the user of high-speed rail private network, and only common network user.At this point, common network eNB can do nothing UE, i.e. the UE still keep access common network eNB and without migration.

305, common network eNB judge in the resident whether most of identification lists of public network cell nearby of historical cell of UE.

When common network eNB judges to obtain UE switching frequency greater than preset value in step 303, step 305 can be continued to execute, and the information of common network cell neighbouring along the high-speed rail configured according to step 202 judges UE whether in high-speed rail.

Specifically, common network eNB can judge in the whether most of lists of public network cell nearby of UE historical cell according to the information of neighbouring common network cell along the high-speed rail that the historical cell information and step 302 of the record in the historical information of UE configure.Such as, common network eNB can according to the historical cell information of UE (such as, the identification information of historical cell) learn the nearest n times of UE after N number of cell it is different, and in conjunction with the common network cell information near along high-speed rail obtain most of historical cell (such as, it is more than or equal to whole cells of n cell or N number of cell in N number of cell, or specified minimum m cell, such as m=3) when belonging to along the high-speed rail that common network eNB in step 302 is configured common network cell nearby, common network eNB can consider that UE is moved all along high-speed rail, it can think UE in high-speed rail, process proceeds to step 307.Wherein, N and n is positive integer, and n is preset value, and n≤N.

306, if step 305 is judged as NO, common network eNB is without special operation.

When in step 305 common network eNB judge to obtain UE not continuously along high-speed rail near common network cell activity when, it is believed that UE be not be the user of high-speed rail private network, and only common network user.At this point, common network eNB can do nothing UE, i.e. the UE still keeps access common network eNB.

307, common network eNB trigger UE and migrate to high-speed rail private network.

When common network eNB judges to obtain UE switching frequency greater than preset value in step 303, it is believed that for UE in high-speed rail, process can be directly entered step 307, and common network eNB triggers UE and migrates to high-speed rail private network.

Further, when common network eNB judges to obtain UE switching frequency greater than preset value in step 303, common network eNB can also continue to execute step 305, judge whether UE historical cell is most of in public network cell list, when the judging result of step 303 and step 305 is all "Yes", can be by UE in high-speed rail, process enters back into step 307 at this time, and common network eNB triggers UE and migrates to high-speed rail private network.In this way, by judging twice, the accuracy that UE is determined as to high-speed rail private network user can be improved, high-speed rail private network user is more precisely made to use high-speed rail private network, and common network user uses common network, and the communication resource of common network user occupancy private network is avoided to cause private network user communication quality poor, or, private network user is avoided to cause communication quality poor due to using common network to lead to cell frequent switching, so as to further increase the communication quality of high-speed rail private network user.

In one embodiment of the invention, it may include that common network eNB triggers UE to the switching of high-speed rail private network or redirection that common network eNB, which triggers UE to the migration of high-speed rail private network,.

Common network eNB triggers UE and can be realized to the switching of high-speed rail private network by following scheme: common network eNB sends switching request message to core network control node to request to switch to UE into target high-speed rail private network, core network control node receives after switching request message, and switching response message is sent to common network eNB after the resource preparation that target high-speed rail private network carries out switching, eNB is after receiving switching response message, switching command is sent to UE, instruction UE switches to high-speed rail private network.Wherein, core network control node can be mobility management entity (Mobility Management Entity, MME).

In another embodiment of the invention, common network eNB can trigger UE by the way of redirecting and migrate to high-speed rail private network.Such as, common network eNB directly can send wireless heterogeneous networks Connection Release (Radio Resource Control connection release to UE, RRC connection release) message, wherein redirection information is carried in RRC connection release message, it include the frequency point information of the high-speed rail private network of common network eNB configuration in step 301 in redirection information, so that UE weight It is directed to high-speed rail private network cell.

Before step 307 common network eNB triggering UE is migrated to high-speed rail private network, UE can also be controlled, the signal parameter of high-speed rail private network frequency point is measured.Common network eNB can further judge whether the measurement result of the signal parameter for the frequency point to high-speed rail private network that UE is reported meets preset condition at this time.If the measurement result that UE measures the signal parameter of the frequency point of high-speed rail private network meets preset condition, for example, measurement gained RSRP and/or RSRQ is greater than preset value, then executing step 307 again.If the measurement result that UE measures the signal parameter of the frequency point of high-speed rail private network is unsatisfactory for preset condition, migration can not be executed, and UE is continually maintained in first network.

The method of the embodiment of the present invention can be used for user equipment and switch over or redirect between the different networks, so that private network can be used in private network user, common network user can be used common network, can be improved the communication quality of private network user in this way.

Can be by step 301 in the embodiment of the present invention, 303 and 307 triggering UE are migrated to high-speed rail private network.For example, common network eNB can judge whether UE switching frequency is greater than preset value to determine whether UE is high-speed rail private network user by step 303.When UE switching frequency is greater than preset value, it is believed that UE executes step 307 in high-speed rail, i.e., triggers UE according to the frequency point of the high-speed rail private network in step 301 and migrate to high-speed rail private network.

Can also be by step 301 in the embodiment of the present invention, 302,305 and 307 triggering UE are migrated to high-speed rail private network.For example, common network eNB, which can configure along high-speed rail the information of common network cell nearby by step 302 and judge whether UE moves along high-speed rail along the line in conjunction with the historical information of UE, determines whether UE is high-speed rail private network user.When judging UE along moving along high-speed rail, it is believed that UE is high-speed rail private network user, and then executes step 307, i.e., triggers UE according to the frequency point of the high-speed rail private network in step 301 and carry out network migration.

UE can also be triggered by all steps of step 301 to 307 in the embodiment of the present invention to migrate to high-speed rail private network.At this point, judged twice by step 303 and step 305, can increase judge high-speed rail private network user whether the accuracy in high-speed rail, and then the communication quality of high-speed rail private network user can be further increased.

Fig. 4 is the schematic flow chart of the network migration method of the UE of yet another embodiment of the invention.It is illustrated so that first network is common network, executing subject access network equipment of second network for dedicated network (for example, high-speed rail private network), method shown in Fig. 4 is common network eNB as an example below.Wherein, for dedicated network for covering specified traffic route region, there is overlapping in the overlay area of common network and dedicated network.

The historical information of 401, common network eNB acquisition UE.

The method that common network eNB obtains the historical information of UE can be similar with the acquisition methods of step 301, and to avoid repeating, details are not described herein.

In one embodiment of the invention, when the historical information of UE may include that UE is resident in history base station, historical measurement that UE measures the signal parameter of the frequency point of high-speed rail private network.The temporal information that can also include the identification information for the historical cell that UE was resident in the historical information of UE and be resident in each historical cell.

Common network eNB can also configure the frequency point of high-speed rail private network, and using the frequency point as the frequency point of the high-speed rail UE target network returned.

402, common network eNB send measurement configuration information to UE, to control the signal parameter of UE measurement target frequency point.

Common network eNB is measured to UE sending measuring configuration information therein is accessed with controlling UE to the signal parameter of target frequency point.Specifically, measurement configuration information may include measurement object (for example, signal parameter of target frequency point) and measurement trigger condition.Measurement trigger condition is used to limit the condition that triggering UE measures the signal parameter of target frequency point.For example, measurement trigger condition can be higher than certain value lower than a certain setting value or high-speed rail private network signal strength for the signal strength of the common network of service UE.The measurement configuration information of the embodiment of the present invention can not include measurement trigger condition, for example, common network eNB can set a time cycle, period control UE measures the signal parameter of target frequency point at every fixed time.

Signal parameter in the embodiment of the present invention can be Reference Signal Received Power, Reference Signal Received Quality, received signal strength indicator etc..Whether measurement result can also meet the result of given report condition to measure resulting measurement numerical value to signal parameter for measurement numerical value.

If measurement result is measurement numerical value, public network eNB can send measurement configuration information to UE in step 402, and after receiving the measurement result that UE is reported based on measurement configuration information, process is proceeded into step 403, judges whether the numerical value in measurement result meets preset condition.Preset condition can be greater than preset value for signal quality or signal strength, alternatively, preset condition can also be less than preset value for noise quality or noise intensity.

Measurement configuration information can also be the system of high-speed rail private network including the measurement object of UE, measure report condition, private network cell of measurement etc..For example, UE can be measured according to signal parameter of the measurement configuration information to target frequency point, when measurement result meets measurement report condition, UE can be to common network eNB report measurement results.When measurement result is unsatisfactory for measurement report condition, UE does not just need to report Measurement result.Measurement result can be the signal quality of target frequency point or the measured value of signal strength.Report condition can threshold value to be greater than setting when signal quality or signal strength when, report condition can also be less than setting value for noise quality or noise intensity.

In the embodiment of the present invention, the tandem of step 401 and step 402 is without limitation.

403, measurement result is added to the historical information of UE by common network eNB.

In one embodiment of the invention, measurement result can be the numerical value of measuring signal parameter, or instruction information.The instruction information can be used to indicate whether the numerical value of measurement parameter meets preset condition, for example, instruction information indicates that measuring resulting numerical value meets preset condition for 1, indicate that information indicates that measuring institute's value is unsatisfactory for preset condition for 0.Preset condition can be greater than preset value for signal quality or signal strength, alternatively, preset condition can also be less than preset value for noise quality or noise intensity.

Common network eNB can increase the instruction information in step 403 in the historical information of UE, and measurement result is filled out in instruction information.When UE continuation switches between different eNB, the history information transmittance of the UE of instruction information can also will be carried to next target eNB.

404, common network eNB judge whether most measurement results all meet the first preset condition in the historical information of UE.

Common network eNB can analyze all measurement results in the historical information of UE or the measurement result in designated time period, when the measured value of signal quality or signal strength more than the target frequency point specified number is greater than the threshold value of setting, it is believed that UE is near high-speed rail route.For example, when the signal quality for the target frequency point that UE is measured every time or signal strength are both greater than the threshold value set, it is believed that UE determines UE in high-speed rail along moving along high-speed rail.Alternatively, when m value is both greater than the threshold value set in the measured value that the M signal quality or signal strength that obtain when UE is measured M times obtain, it is believed that UE is moved along the line along high-speed rail, user UE being determined as in high-speed rail.Wherein, M and m is positive integer, and m is preset value, and m≤M.Alternatively, when the measured value of specified quantity (for example, five) is greater than corresponding preset threshold in given time period, it is believed that UE is moved along the line along high-speed rail, user UE being determined as in high-speed rail.

For another example, when whether meeting the instruction information of preset condition including the measurement result that UE is reported in the UE historical information of acquisition, whether the number that eNB can be 1 according to instruction information judge UE in high-speed rail.It is all 1 if there is being more than the instruction information specified number, it is believed that for UE in high-speed rail, i.e. eNB can consider that the measurement result received meets preset condition, need to migrate UE to high-speed rail private network.

In the embodiment of the present invention, to step 404 and step 402,403 execution sequence with no restrictions.I.e., it is possible to first carry out step 402,403, by this measurement result be saved in UE historical information it It executes step 404 again afterwards and judges whether measurement result meets preset condition according to UE historical information.Step 404 can also be first carried out according to judging whether measurement result (not including this measurement result) meets preset condition in UE historical information, step 402 is executed again, the signal parameter of 403 pairs of private network frequency points measures, and this measurement result is saved in the historical information of UE.

405, if the judging result of step 404 be it is no, public network network eNB is without special operation.

406, common network eNB judge whether connected state UE switching frequency is greater than preset value.

If the judging result of step 404 be it is yes, common network eNB execute step 406. step 406 implementation it is identical with the implementation of step 303, to avoid repeating, details are not described herein.

407, if step 406 is judged as NO, common network eNB is without special operation.

When step 406 judgement obtains UE switching frequency less than or equal to preset value, any processing can not be done to UE, that is, still maintains the access of original common network eNB.

408, common network eNB trigger UE and migrate to high-speed rail private network.

Common network eNB can obtain the historical information of UE in step 403, and determine that UE in high-speed rail, and triggers UE and migrates to high-speed rail private network according to the instruction information in the historical information of UE.

Common network eNB further can also judge UE switching frequency by step 406 after step 404.Whether common network eNB can judge UE in high-speed rail in conjunction with instruction information and switching frequency, when measurement results most in the historical information of UE meet preset condition and UE switching frequency is greater than preset value, it is considered that UE is in high-speed rail, process proceeds to step 408, and common network eNB triggers UE according to measurement result and moves to high-speed rail private network.

Common network eNB in the embodiment of the present invention triggers UE and can be realized from common network to the migration of high-speed rail private network by switching from common network to high-speed rail private network or redirecting.Specific migration pattern is referred to step 307, and to avoid repeating, details are not described herein.

It, can be based on the measurement result that the signal parameter of the frequency point to high-speed rail private network measures to determine whether switching from common network to the switching of high-speed rail private network in one embodiment of the present of invention.For example, common network eNB may determine that whether the measurement result of the signal parameter for the frequency point to high-speed rail private network that UE is reported meets the second preset condition before step 407 common network eNB triggering UE is migrated to high-speed rail private network.If UE meets the second preset condition to the measurement result that the signal parameter of the frequency point of high-speed rail private network measures, for example, measurement gained RSRP and/or RSRQ is greater than preset value, then executing step 407 again.If the measurement result that UE measures the signal parameter of the frequency point of high-speed rail private network is unsatisfactory for the second preset condition, migration can not be executed, and UE is continually maintained in first network.

The second preset condition in the embodiment of the present invention can phase with the first preset condition in step 404 Together, it can also be different, the present invention is without limitation.

Can be by step 401 in the embodiment of the present invention, 402,403,404,407 triggering UE are migrated to high-speed rail private network.Determine that UE whether in high-speed rail, and triggers user in high-speed rail and migrates to high-speed rail private network according to measurement result.

UE can also be triggered by all steps of step 401 to 407 in the embodiment of the present invention to migrate to high-speed rail private network.It combines and again migrates UE to high-speed rail private network in this way after determining UE in high-speed rail, accuracy of the determining UE in high-speed rail can be increased in this way, and then the communication quality of high-speed rail private network user can be further increased.At this moment the judgement sequence of step 403 and step 405 can be interchanged, and the present invention is without limitation.

Above-mentioned Fig. 3 and Fig. 4 is provided from the historical information of UE and is determined specific embodiment that UE is migrated from from common network to dedicated network.The specific embodiment that UE is migrated from dedicated network to common network is described in detail below with reference to Fig. 5.

Fig. 5 is the schematic flow chart of the network migration method of the UE of yet another embodiment of the invention.Method shown in fig. 5 is illustrated so that first network is dedicated network, the second network is common network, the executing subject access network equipment of method shown in fig. 5 is private network eNB as an example.For dedicated network for covering specified traffic route region, there is overlapping in the overlay area of common network and dedicated network.

The method that high-speed rail private network eNB obtains the historical information of UE can be similar with the acquisition methods of step 301, and to avoid repeating, details are not described herein.

502, high-speed rail private network eNB judge whether connected state UE switching frequency is less than preset value.

In the embodiment of the present invention step 502 high-speed rail private network eNB judge connected state UE switching frequency whether be less than common network eNB in the method and steps 503 of preset value judge connected state UE switching frequency whether be greater than preset value method it is similar, in this not go into detail.

503, if step 502 is judged as that switching frequency is greater than or equal to preset value, high-speed rail private network eNB is without special operation.

When high-speed rail private network eNB judges to obtain UE switching frequency more than or equal to preset value in step 502, it is believed that UE is in high-speed rail.At this point, high-speed rail private network eNB can do nothing UE, i.e. the UE still keeps access private network eNB.

504, high-speed rail private network eNB trigger UE and migrate to common network.

When step 502 judgement obtains UE switching frequency less than preset value, process may proceed to step 504, and high-speed rail private network eNB triggering UE moves to common network.Here migration can be switching, It can be redirection.The switching or redirect process that specific migration process is referred in Fig. 3 and Fig. 4, in this not go into detail.

It, can be based on the measurement result that the signal parameter of the frequency point to high-speed rail private network measures to determine whether switching from common network to the switching of high-speed rail private network in one embodiment of the present of invention.For example, can also control UE before step 504 high-speed rail private network eNB triggering UE is migrated to common network and be measured to the signal parameter of common network frequency point.High-speed rail private network eNB can further judge whether the measurement result of the signal parameter for the frequency point to common network that UE is reported meets third preset condition at this time.If the measurement result that UE measures the signal parameter of the frequency point of common network meets third preset condition, for example, measurement gained RSRP and/or RSRQ is greater than preset value, then executing step 504 again.If the measurement result that UE measures the signal parameter of the frequency point of common network is unsatisfactory for preset condition, migration can not be executed, and UE is continually maintained in first network.
