Embodiment

Below in conjunction with the accompanying drawing in the embodiment of the present invention, the 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.Based on the embodiment 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.

Technical scheme of the present invention, can be applied to various communication systems, for example: global system for mobile communications (GSM, Global System of Mobile communication), code division multiple access (CDMA, CodeDivision Multiple Access) system, Wideband Code Division Multiple Access (WCDMA) (WCDMA, Wideband CodeDivision Multiple Access Wireless), GPRS (GPRS, General PacketRadio Service), Long Term Evolution (LTE, Long Term Evolution) etc.

Terminal, can be described as subscriber equipment (UE, User Equipment), also can be referred to as mobile terminal (Mobile Terminal), mobile subscriber equipment etc., can be through wireless access network (for example, RAN, RadioAccess Network) communicate with one or more core net, terminal can be mobile phone (or being called " honeycomb " phone), also can be the computer with mobile terminal, for example, can be portable, pocket, hand-hold type, built-in computer or vehicle-mounted mobile device, they and wireless access network exchange language and/or data.

Base station can be the base station (BTS, Base Transceiver Station) in GSM or CDMA, also can be the base station (NodeB) in WCDMA, can also be the evolved base station (eNB or e-NodeB, evolutional Node B) in LTE, the present invention be to this and be not construed as limiting.

Fig. 1 is the flow chart of the method for the radio network optimization based on virtual switching of one embodiment of the invention.The method of Fig. 1 is carried out by terminal.

101, determine the Target cell of the virtual switching of terminal.

102, the parameter of the parameter of the Serving cell of configurating terminal and/or configuration Target cell, so that terminal meets the switching condition that is switched to Target cell from Serving cell.

103, send the first measurement report to base station, the first measurement report comprises the parameter of Serving cell and the parameter of Target cell.

104, receive the switching command that base station sends according to the first measurement report.

105, the switching command sending according to base station is carried out and is switched, to determine network problem according to the result of switching.

Should be understood that in the embodiment of the present invention for determining that according to the result of switching the executive agent of this step of network problem is not construed as limiting.Executive agent can be terminal, or terminal can send to miscellaneous equipment by the result of virtual switching, so that miscellaneous equipment is determined network problem according to the result of switching, as base station.Embodiment of the present invention executive agent, take terminal as example, is only used to help those skilled in the art to understand better the embodiment of the present invention, and leaves no choice but limit the scope of the invention.

Alternatively, as an embodiment, in step 101, under a kind of implementation, terminal can be defined as all or part of neighbor cell in the first Neighboring Cell List the Target cell of the virtual switching of terminal one by one.Administrative staff can set in advance the first Neighboring Cell List in terminal, obtain the first Neighboring Cell List from terminal, and terminal can also be obtained the first Neighboring Cell List from network management system.For example, terminal is by SIM(Subscriber Identity Module, subscriber identification module) card authentication carrys out the wireless network of access carrier, and login wireless network management system, downloads the first Neighboring Cell List.Particularly, terminal selects a neighbor cell to be defined as the Target cell of virtual switching in the first Neighboring Cell List, or terminal is defined as the multiple neighbor cells in the first Neighboring Cell List the Target cell of virtual switching one by one.Further, terminal can be measured the signal of the whole neighbor cells in the first Neighboring Cell List, obtains the first signal measured value (for example signal strength signal intensity) of each neighbor cell.While being less than first signal threshold value due to the first signal measured value of neighbor cell, after making to be switched to neighbor cell, cannot set up wireless link, the neighbor cell that terminal can be more than or equal to first signal measured value first signal threshold value is defined as the Target cell of virtual switching one by one, or terminal can select the neighbor cell of signal strength values maximum to be defined as the Target cell of virtual switching.

Under another kind of implementation, all or part of neighbor cell in the second Neighboring Cell List that terminal can issue base station is defined as the Target cell of the virtual switching of terminal one by one.For example, in calling procedure, terminal receives the SIB(System Information Block that base station issues, System information block) 11, SIB 11 comprises the second Neighboring Cell List.Terminal selects a neighbor cell to be defined as the Target cell of virtual switching in the second Neighboring Cell List, and deletes the information of other neighbor cells in the second Neighboring Cell List; Or terminal is defined as the multiple neighbor cells in the second Neighboring Cell List the Target cell of virtual switching one by one.Further, terminal can be measured the signal of the whole neighbor cells in the second Neighboring Cell List, obtains the secondary signal measured value (for example signal strength signal intensity) of each neighbor cell.While being less than secondary signal threshold value due to the secondary signal measured value of neighbor cell, after making to be switched to neighbor cell, cannot set up wireless link, the neighbor cell that terminal can be more than or equal to secondary signal measured value secondary signal threshold value is defined as the Target cell of virtual switching one by one, or terminal can select the neighbor cell of signal strength values maximum to be defined as the Target cell of virtual switching.

In addition, terminal can also be defined as all or part of neighbor cell in all or part of neighbor cell in the first Neighboring Cell List and the second Neighboring Cell List the Target cell of virtual switching one by one.For example, terminal is defined as the information of first aim community of virtual switching in the first Neighboring Cell List, and the information of second target community that terminal is defined as virtual switching is in the second Neighboring Cell List but do not belong to the first Neighboring Cell List.Wherein, the information of community (for example cell ID), in Neighboring Cell List, that is to say, community belongs to this Neighboring Cell List.

Therefore, terminal can be selected the Target cell of virtual switching neatly, and can overcome the restriction that is subject to network in drive test process on the spot, obtains multiple switching combining, thereby analyzes network problem more comprehensively, more accurately.

Should be understood that the embodiment of the present invention determines that for terminal the mode of the Target cell of virtual switching is not construed as limiting.

Alternatively, as another embodiment, the parameter of Serving cell can comprise following one of at least: terminal receives Timing Advance, the incoming level of reference signal of Serving cell and the quality of reception of the reference signal of Serving cell of reference signal in Serving cell.The parameter of Target cell can comprise following one of at least: terminal receives Timing Advance, the incoming level of reference signal of Target cell and the quality of reception of the reference signal of Target cell of reference signal in Target cell.In step 102, for example, in calling procedure, the parameter value TA1 of the Timing Advance of terminal configuration Serving cell reception reference signal is greater than the parameter value TA2 of the Timing Advance of Target cell reception reference signal, and TA1 is greater than the parameter value TA0 of the Timing Advance of urgent switching reception reference signal, makes terminal meet the Timing Advance switching condition of the reception reference signal that is switched to Target cell.Again for example, in calling procedure, the quality of reception of terminal configuration Serving cell is poorer than the quality of reception of Target cell, and the mean value of the uplink quality of Serving cell is greater than urgent switching uplink quality restriction within a certain period of time, makes terminal meet the quality of reception switching condition that is switched to Target cell.Again for example, in calling procedure, the incoming level of terminal configuration Serving cell is greater than the incoming level of Target cell, simultaneously the transmission quality of the quality of reception of configuration service community and Serving cell poorer than the quality of reception of Target cell, lower than disturbance switching quality threshold, makes terminal meet the disturbance switching condition that is switched to Target cell.Again for example, in calling procedure, the incoming level of terminal configuration Serving cell is less than the incoming level of Target cell, makes terminal meet the incoming level switching condition that is switched to Target cell.Further, terminal can continuity the parameter of configuration service community, ground and Target cell, until terminal receives the switching command that network side sends.For example, as shown in Figure 2, the terminal for the first time incoming level of (MR1 moment) configuration service community is V1, the incoming level of (MR2 moment) configuration service community is V2 for the second time ... presenting staged successively decreases, until after the incoming level of the 5th (MR5 moment) configuration service community of terminal is V5, terminal receives the order that is switched to Target cell that network side sends.

Should be understood that the embodiment of the present invention does not limit for mode and the choosing of parameter of the parameter of terminal configuration Serving cell and Target cell.

Alternatively, as another embodiment, in step 105, the switching command that terminal can send according to base station is carried out and is switched, and determines network problem according to the result of switching.Further, terminal can, according to the result of switching, and be determined network problem in conjunction with the first parameter.Wherein, the first parameter comprise following one of at least: engineering parameter, the first Neighboring Cell List setting in advance or the first Neighboring Cell List obtaining from network management system etc.

The first community Neighboring Cell List Zhong community and the second Neighboring Cell List may be identical or different.In definite network problem process, can, using the first Neighboring Cell List as the benchmark judging, that is to say, the first Neighboring Cell List Zhong community is determined under the prerequisite of the neighbor cell of the Serving cell of terminal again to network problem.Certainly, also can the second Neighboring Cell List as the benchmark of judgement.

In addition, terminal can will be presented on the interface of terminal or electronic chart and carry out alarm with the corresponding Target cell of network problem, or terminal has the Target cell of network problem with form output.Therefore, can point out immediately a line engineering staff, so that a line engineering staff provides measure targetedly to the network problem occurring.Like this, be conducive to improve handover success rate, thereby provide better service for user.Terminal can also be by the information recording of network problem at examining report, by examining report FTP(File TransferProtocol, file transfer protocol (FTP)) mode sends to test and management server; Or examining report is sent to administrative staff's mailbox by lettergram mode; Or by examining report SMS(Short MessageService, short message service) mode sends to administrative staff.Therefore, administrative staff obtain after network problem by examining report, can provide measure targetedly.Like this, be conducive to improve handover success rate, thereby provide better service for user.

For example, in terminal, all or part of neighbor cell in above-mentioned the first Neighboring Cell List is defined as the Target cell of virtual switching of terminal one by one, if be switched to Target cell Cell 1 failure, determines that Cell 1 is for abnormal community.Further, terminal is presented on Cell 1 on the interface of terminal or electronic chart and carries out alarm, Cell 1 use red-label.Or terminal can be exported Cell 1 by form.Or terminal records examining report, comprise at examining report the information that Cell 1 is abnormal community.

Again for example, all or part of neighbor cell in above-mentioned the first Neighboring Cell List is defined as one by one the Target cell of virtual switching of terminal in terminal, if in the second Neighboring Cell List that the information of Target cell success and this Target cell that is switched to does not issue in base station, determine that this Target cell is for adjacent area Lou Pei respective cell in the second Neighboring Cell List.Particularly, as shown in Figure 3, the neighbor cell in the second Neighboring Cell List that terminal receives is 303 and 304, and terminal actual measurement is all very faint to

neighbor cell

303 and 304 signal strength values.Meanwhile, the neighbor cell in the first Neighboring Cell List 302 is defined as to Target cell and carries out virtual switching and be switched to neighbor cell 302 successes, actual measurement is larger to the signal strength values of neighbor cell 302.Incorporation engineering parameter finds that the deflection between neighbor cell 302 and Serving cell 301 is between 120 ° to 240 °, distance between neighbor cell 302 and Serving cell 301 is less than the 3rd distance threshold, and there is no other communities between neighbor cell 302 and Serving cell 301, determine that neighbor cell 302 is adjacent area Lou Pei respective cell in the second Neighboring Cell List.

Further, terminal is presented on neighbor cell 302 on the interface of terminal or electronic chart and carries out alarm, neighbor cell 302 use Green Markers.Or terminal can be exported neighbor cell 302 by form.Or terminal records examining report, comprise the information of neighbor cell 302 for adjacent area Lou Pei respective cell in the second Neighboring Cell List at examining report.

Again for example, whole neighbor cells in above-mentioned the first Neighboring Cell List are defined as one by one the Target cell of virtual switching of terminal in terminal, if be switched to whole neighbor cells all the signal measurements of failure and whole neighbor cells of measuring be all less than the 3rd default signal threshold value, determine that network problem is the island effect of Serving cell area covered.Further, terminal by the information recording of the island effect of Serving cell area covered in examining report.

Again for example, all or part of neighbor cell in the second Neighboring Cell List base station being issued in terminal is defined as the Target cell of virtual switching of terminal one by one, if the information of Target cell failure and this Target cell that is switched to, in the first Neighboring Cell List, determines that this Target cell is abnormal community.

Again for example, all or part of neighbor cell in the second Neighboring Cell List base station being issued in terminal is defined as the Target cell of virtual switching of terminal one by one, if the information of Target cell success and this Target cell that is switched to is not in the first Neighboring Cell List, determine that this Target cell is abnormal community, further, if the distance inquiring in engineering parameter between this Target cell and Serving cell is less than the 3rd distance threshold, the angle a of the deflection between this Target cell and Serving cell is: 120 °≤a≤240 °, and between this Target cell and Serving cell, there is no other communities, determine that this Target cell is adjacent area Lou Pei respective cell in the first Neighboring Cell List, again further, terminal is added this Target cell to first Neighboring Cell List.

Again for example, all or part of neighbor cell in the second Neighboring Cell List base station being issued in terminal is defined as the Target cell of virtual switching of terminal one by one, if the distance that is switched to Target cell failure and inquire between this Target cell and Serving cell in engineering parameter is more than or equal to the first distance threshold, determine that this Target cell is the respective cell of adjacent area polygamy.If the deflection that is switched to Target cell failure and inquire between this Target cell and Serving cell in engineering parameter differs 180 °, determine that this Target cell is the respective cell of adjacent area polygamy in the second Neighboring Cell List.

Again for example, all or part of neighbor cell in the second Neighboring Cell List base station being issued in terminal is defined as the Target cell of virtual switching of terminal one by one, if the distance that is switched to Target cell success and inquire between this Target cell and Serving cell in engineering parameter is more than or equal to second distance threshold value, deflection between this Target cell and Serving cell differs 180 °, determines that this Target cell is the abnormal community of reverse connection of antenna.Particularly, as shown in Figure 4, the neighbor cell in the second Neighboring Cell List that terminal receives is 403,404 and 406, and neighbor cell 403,404 and 406 is defined as to the Target cell of virtual switching one by one and is switched to all successes of neighbor cell 403,404 and 406.Wherein, the distance inquiring in engineering parameter between neighbor cell 406 and Serving cell 401 is more than or equal to second distance threshold value, be that neighbor cell 406 is actually non-adjacent cell, between Serving cell 401 and non-adjacent cell 406, there is the neighbor cell 405 belonging in the first Neighboring Cell List, and deflection between non-adjacent cell 406 and Serving cell 401 differs 180 °, determine that neighbor cell 405 and non-adjacent cell 406 may be the abnormal community of reverse connection of antenna.

Again for example, also can be using the second Neighboring Cell List as the benchmark judging, whole neighbor cells in the second Neighboring Cell List base station being issued in terminal are defined as the Target cell of virtual switching of terminal one by one, if be switched to whole neighbor cells all the signal of failure and whole neighbor cells of measuring be all less than default threshold value, determine that network problem is the island effect of Serving cell area covered.

Again for example, in terminal, all or part of neighbor cell in the first Neighboring Cell List is defined as one by one to the Target cell of the virtual switching of terminal, all or part of neighbor cell in the second Neighboring Cell List simultaneously base station being issued is defined as in the situation of Target cell of the virtual switching of terminal one by one, if be switched to the failure of first object community and be switched to the second Target cell success, determine first object community and the second Target cell reverse connection of antenna; Wherein, first object community is the neighbor cell of the first Neighboring Cell List, and the second Target cell is that the neighbor cell of the second Neighboring Cell List and the information of the second Target cell is not in the first Neighboring Cell List.Particularly, as shown in Figure 5, suppose that the whole neighbor cells in the first Neighboring Cell List are neighbor cell 502,503,504 and 506, whole neighbor cells in the second Neighboring Cell List are neighbor cell 502,503 and 505, terminal is defined as one by one the Target cell of virtual switching by neighbor cell 502,503,504 and 505 and is switched to neighbor cell 502,503 and 505 successes, is switched to neighbor cell 504 failures.Neighbor cell 505 does not belong to the first Neighboring Cell List, and neighbor cell 505 is actually non-adjacent cell, determine neighbor cell 504 may with the reverse connection of antenna of non-adjacent cell 505 or neighbor cell 504 may with the reverse connection of antenna of non-adjacent cell 506.

In addition, terminal can be by the information recording of network problem in examining report, alternatively, as a kind of implementation, the list items that examining report comprises has: operator name, zone name, abnormal cell ID, adjacent area polygamy, adjacent area leak join, island effect, area covered and reverse connection of antenna etc.For example, the respective cell that neighbor cell 503 is reverse connection of antenna, terminal can mark on corresponding network problem " reverse connection of antenna " (for example marking with color mark or with symbol " * "), there is the cell ID of the neighbor cell 503 of network problem in record, by lettergram mode, examining report is sent to administrative staff's mailbox.It should be noted, the embodiment of the present invention for terminal by the information recording of network problem in the mode of examining report and send to administrative staff to be not construed as limiting examining report in which way.
