Refer to Fig. 1, Fig. 1 is embodiment schematic diagram of measurement result report method of the present invention, and the method for the present embodiment comprises:
101, user equipment (UE) is determined the circuit that prestores under the current trip circuit of user according to the historical toggle path of UE, and wherein, each circuit that prestores is preset with corresponding community toggle path;
The UE of the present embodiment can be the electronic equipments such as mobile phone, mobile phone.
In the present embodiment, the circuit that prestores in UE is all high ferro working lines that prestore, and circuit such as Jing-Hu Railway, Hu Jingxian, Ning Huxian, Shanghai-Nanjing Railway Line etc. prestore.Each website that comprises high ferro operation passage in transit in circuit prestores.Each circuit that prestores is preset with corresponding community toggle path, and community toggle path is kept in UE equally in advance.UE just can determine the circuit that prestores under the current trip circuit of user according to the historical toggle path of UE, and wherein, the historical toggle path of UE is made up of the historical Serving cell of UE.
102, UE is according to community toggle path corresponding to the determined circuit that prestores and searching Target cell, Serving cell;
Target cell is herein the community that the next one preset will switch.
103, UE measures Target cell, obtains the measured value of Target cell;
104, UE revises the measured value of Target cell, so that the measured value of Target cell increases;
Under normal circumstances, in soft switching process, UE can measure multiple neighbor cells, only has the measured value of working as a certain community to meet report condition, the measured value of Ji Gai community is more than or equal to default while reporting threshold value, and UE just can report to access network equipment the measured value of this community.The access network equipment here includes but not limited to: base station (Node B), evolved base station (evolved Node B, eNB), radio network controller (radio network controller, RNC), base station controller (Base Station Controller, BSC), base transceiver station (Base Transceiver Station, BTS).
In the present embodiment, owing to having determined the next Target cell that will switch in step 102, therefore, in order as early as possible Target cell to be reported to access network equipment, after UE measures the measured value of Target cell, UE can revise the measured value of Target cell, so that the measured value of Target cell increases, makes like this measured value of Target cell more easily reach and reports threshold value.

In the present embodiment, because UE can determine user's trip circuit, thereby can know the Target cell that is about to switch, the measured value of Target cell is revised so that the measured value of Target cell more easily reaches and reported threshold value, be greater than while reporting threshold value at the measured value of revised Target cell, the measured value of revised Target cell is reported to access network equipment, can guide like this access network equipment in time Target cell to be added to Active Set, thereby raising handover success rate, reduces communication number of dropped calls.
For ease of understanding, with a specific embodiment, the measurement result report method in the embodiment of the present invention is described below, refer to Fig. 2, the method for the present embodiment comprises:
201, UE is starting point taking Serving cell, obtains the historical toggle path being made up of preset number N historical Serving cell of switching continuously;
Wherein, Serving cell is the community at the current place of UE, and historical Serving cell is that UE enters after high ferro circuit, for UE provided the community of serving.
202, UE is divided into N by historical toggle path to subtract i(is N-i) individually switch the switching subpath forming by i time, wherein i is less than N;
203, the likely value of institute of UE traversal i, the matching degree score of each circuit that prestores when calculating i gets different value, and the matching degree score of each circuit that prestores is cumulative;
The circuit that prestores is all high ferro working lines that prestore in UE, and circuit such as Jing-Hu Railway, Hu Jingxian, Ning Huxian, Shanghai-Nanjing Railway Line etc. prestore.Each website that comprises high ferro operation passage in transit in circuit prestores.Each circuit that prestores is preset with corresponding community toggle path, and community toggle path is kept in UE equally in advance.
In the present embodiment, when UE gets different value according to i, the match condition of the community toggle path that the individual switching subpath being made up of i switching of N-i is corresponding with each circuit that prestores is calculated the matching degree score of each circuit that prestores, and by cumulative the each matching degree score of circuit in the time that i gets different value that prestore.
204, the circuit that prestores that the highest matching degree score or matching degree score are greater than default matching degree threshold value by UE is defined as the circuit that prestores under the current trip circuit of user;
Step 201-204 is the process that UE determines the affiliated circuit that prestores of the current trip circuit of user, cites an actual example and describes below:
If UE take Serving cell as starting point, 10 historical Serving cells of switching are continuously got, be that preset number N is 10, accordingly, the span of i is 1-9, and the mark of each historical Serving cell is respectively 1,2,3,4,5,6,7,8,9,10, and historical toggle path is 1 → 2 → 3 → 4 → 5 → 6 → 7 → 8 → 9 → 10, wherein, arrow represents switching direction.
In the time that i value is 1, be divided into 9 by historical toggle path and switched the switching subpath forming by single, 9 switch subpath and are respectively: 1 → 2,2 → 3,3 → 4,4 → 5,5 → 6,6 → 7,7 → 8,8 → 9,9 → 10.By these 9 switch subpaths respectively the community toggle path corresponding with each circuit that prestores mate, this coupling comprises the coupling of cell ID and mating of switching direction.
If prestore, the community toggle path of circuit one correspondence is (A → B → 2 → 3 → 4 → 5 → C → 7 → 8 → D → E → F → G → H), this community toggle path mates with above-mentioned 94 of switching in subpath, the switching subpath of coupling is respectively 2 → 3,3 → 4,4 → 5,7 → 8, and it is the matching degree score of 1 o'clock in i value that this number is multiplied by the default weight coefficient circuit one that can obtain prestoring.Wherein, default weight coefficient can arrange according to the length of switching subpath, and the length of switching subpath is longer, and what weight coefficient can be arranged is larger.Can be for example that 1(single switches by switching subpath length) time weight coefficient be made as 1, length is twice switching of 2() time be made as 2, length is that 3(switches for tri-times) time be made as 4, length is to be made as 8 at 4 o'clock, the like, length is to be made as 256 at 9 o'clock.So in the above example, the matching degree that the circuit 1 that prestores is 1 o'clock in i value must be divided into 4*1,4 points.
In the time that i value is 2, be divided into 8 switching subpaths that formed by twice switching by historical toggle path, 8 switch subpath and are respectively: 1 → 2 → 3,2 → 3 → 4,3 → 4 → 5,4 → 5 → 6,5 → 6 → 7,6 → 7 → 8,7 → 8 → 9,8 → 9 → 10.According to these 8 the matching degree scores of switching the each circuit that prestores of matching degree calculating of the subpath community toggle path corresponding with each circuit that prestores.In example above, the circuit one that prestores is the matching degree score 2*2 of 2 o'clock in i value, 4 points.
In the time that i value is 3, be divided into 7 by historical toggle path and switch by three times the switching subpath forming, 7 switch subpath and are respectively: 1 → 2 → 3 → 4,2 → 3 → 4 → 5,3 → 4 → 5 → 6,4 → 5 → 6 → 7,5 → 6 → 7 → 8,6 → 7 → 8 → 9,7 → 8 → 9 → 10.According to these 7 the matching degree scores of switching the each circuit that prestores of matching degree calculating of the subpath community toggle path corresponding with each circuit that prestores.In example above, the circuit one that prestores is the matching degree score 1*4 of 3 o'clock in i value, 4 points.
The like, in the time that i value is 9, switch subpath identical with historical toggle path, if matched, need to be multiplied by weight coefficient 256.
Travel through successively the likely value of institute of i, by cumulative the each matching degree score of path in the time that i gets different value that prestore, the highest matching degree score or matching degree score are greater than to the prestore circuit of circuit under the current trip circuit of user that prestore of default matching degree threshold value.
In example above, the matching degree score 4+4+4 that the circuit one that prestores is final, 12 points, if certain circuit that prestores mates completely with historical toggle path, the final matching degree of this circuit that prestores must be divided into:
9*1+8*2+7*4+6*8+5*16+4*32+3*64+2*128+1*256=1013。
Suppose that matching degree threshold value is 128, final matching degree score can be greater than to 128 the circuit that prestores and be defined as the circuit that prestores under the current trip circuit of user.
205, UE is according to community toggle path corresponding to the determined circuit that prestores and searching Target cell, Serving cell;
UE is the position in community toggle path corresponding to the determined circuit that prestores according to Serving cell, searches default next switching cell, and default next switching cell is Target cell.
206, UE measures Target cell, obtains the measured value of Target cell;
The measured value of the Target cell obtaining in the present embodiment is: received signal code power (Received Signal Code Power, RSCP) with band in signal power on chip divided by power density Ec/N0(under UMTS network), or received signal level Rxlev(is under GSM network).
207, UE revises the measured value of Target cell, so that the measured value of Target cell increases;
Under normal circumstances, in soft switching process, UE can measure multiple neighbor cells, only has the measured value of working as a certain community to meet report condition, the measured value of Ji Gai community is more than or equal to default while reporting threshold value, and UE just can report to access network equipment the measured value of this community.The access network equipment here includes but not limited to: base station (Node B), evolved base station (evolved Node B, eNB), radio network controller (radio network controller, RNC), base station controller (Base Station Controller, BSC), base transceiver station (Base Transceiver Station, BTS).
In the present embodiment, owing to having determined the next Target cell that will switch in the step above, therefore, in order as early as possible Target cell to be reported to access network equipment, after UE measures the measured value of Target cell, measured value to Target cell is revised, and the measured value of Target cell is increased, and the measured value of Target cell more easily reaches and reports threshold value like this.
In specific implementation, UE to the measured value correction of Target cell can be: the measured value of Target cell (RSCP and Ec/N0 or Rxlev) is increased to preset bias, for example the measured value of Target cell can be increased to 3dB, even under the current covering in UMTS network of UE, measured value RSCP and Ec/N0 are increased to 3dB, if under the current covering in GSM network of UE, measured value Rxlev is increased to 3dB.After the measured value of Target cell is increased to preset bias, illustrate that the energy of Target cell is stronger, more easily meet report condition; Or the measured value of Target cell does not meet report condition originally, after the measured value of Target cell is increased to preset bias, the measured value of Target cell has been more than or equal to the default threshold value that reports, and has met report condition.
208, the measured value of revised Target cell is reported radio network controller access network equipment by UE.
The measured value of revised Target cell can increase, if the measured value of revised Target cell has met report condition, UE can report access network equipment by the measured value of revised Target cell, to guide in time access network equipment that Target cell is added to Active Set, like this, when access network equipment sends after switching command, UE just can be switched to Target cell quickly and accurately, the concrete implementation procedure of switching, be known technology to those skilled in the art, do not repeated them here.
In the present embodiment, because UE can determine user's trip circuit, thereby can know the Target cell that is about to switch, the measured value of Target cell is revised so that the measured value of Target cell more easily meets and reports threshold value, UE can report access network equipment by Target cell in time like this, in time Target cell is added to Active Set with guiding access network equipment, thereby improve handover success rate, reduce communication number of dropped calls.
