The base station is added the information of definite miss-configured neighboring cells in the neighbor cell configuration information table of preserving this base station self;
Preferable, comprise further that after step 12 message of configuration successful is sent to described terminal in the base station, and notify described terminal and described miss-configured neighboring cells to carry out operating in soft handover.
Below be introduced with specific embodiment:
In CDMA HRPD network system, when terminal moves to another sub-district from a sub-district, and in the time of need carrying out operating in soft handover, the pilot signal that in the process of switching, needs to seek Target cell, when terminal thinks that this pilot signal can finish traffic operation, and when the pilot signal of this cell-of-origin, terminal place has been lower than a certain threshold value, determine to carry out operating in soft handover.Terminal reports the base station that this terminal belongs to the pilot signal that searches, and the Target cell that sends this pilot signal is searched in this base station in the neighbor cell configuration information table of preserving, then notify terminal to carry out operating in soft handover at Target cell when searching successfully; Otherwise think that this pilot signal is that pilot signal is joined in the adjacent area leakage, when joining phenomenon, the adjacent area leakage will cause this terminal to communicate when producing with Target cell, therefore, need carry out miss-configured neighboring cells and revise operation, the base station is searched to send with this adjacent area in the neighbor cell configuration information table and is leaked the sub-district of joining the identical pilot signal of pilot signal, and this sub-district is defined as miss-configured neighboring cells, and finishes the subsequent correction operation, as shown in Figure 3, concrete steps are as follows:
Step 21, terminal are searched for all pilot signals in adjacent area collection and residual set, and calculate the signal strength signal intensity of the pilot signal that searches according to predefined computational methods;
Described adjacent area collection is made up of the adjacent sub-district that might participate in soft handover, cell-of-origin, terminal place; Described residual set by pilot frequency intensity can the support terminal signal communication, the adjacent sub-district of cell-of-origin, terminal place forms.Described predefined computational methods are for calculating the method for the signal strength signal intensity of pilot signal in the prior art;
Step 22, the signal strength signal intensity that calculates pilot signal when terminal determine that this pilot signal is enough strong during greater than the signal strength threshold that sets in advance, promptly can carry out demodulation to this pilot signal, and by RouteUpdate message this pilot signal be reported the base station; Carry this pilot signal in the described RouteUpdate message;
The content and the occupation mode of CDMA agreement regulation RouteUpdate message in this step;
Step 23, base station are obtained pilot signal from the RouteUpdate message that receives after, from the neighbor cell configuration information table of self preserving, search the information of the sub-district of sending this pilot signal; When searching successfully, this sub-district as Target cell, is sent to terminal with the information of this Target cell, and sends the message of searching success to terminal, make terminal finish operating in soft handover with Target cell; Otherwise the base station determines that this pilot signal is the miss-configured neighboring cells pilot signal, searches the sub-district of sending the pilot signal identical with this miss-configured neighboring cells pilot signal, and these sub-districts are defined as miss-configured neighboring cells, turns to step 24;
The miss-configured neighboring cells of determining in this step can be one or more;
Step 24, base station are added the information of described miss-configured neighboring cells to miss-configured neighboring cells and are concentrated; Described information comprises that the antenna direction of described cell-of-origin and described miss-configured neighboring cells concerns, terminal is finished the handover information of effective switching and the positional information of described miss-configured neighboring cells between the adjacent sub-district of described miss-configured neighboring cells and described cell-of-origin;
Step 25, the base station is chosen one or more best miss-configured neighboring cells according to antenna direction relation, handoff relation and the distance of cell-of-origin, terminal place with the miss-configured neighboring cells of determining from the miss-configured neighboring cells of determining, and detailed process is as follows:
A, the base station concerns according to described antenna direction, determines concentrate described miss-configured neighboring cells does not have lap with the coverage of described cell-of-origin miss-configured neighboring cells, and adds the miss-configured neighboring cells of determining to first best miss-configured neighboring cells collection;
Determine in this steps A that it is prior art that antenna direction closes, several different methods can be arranged, specifically can be as follows, as shown in Figure 2, A is the coverage of cell-of-origin, B is the coverage of miss-configured neighboring cells, when A does not overlap with the coverage of B, even if base station, terminal place can detect the pilot signal of miss-configured neighboring cells B, the pilot signal that terminal also can't these miss-configured neighboring cells of demodulation, therefore, need removing is concentrated in these miss-configured neighboring cells from described miss-configured neighboring cells;
The miss-configured neighboring cells that concentrate the described first best miss-configured neighboring cells and the adjacent sub-district of described cell-of-origin has been finished effective switching are determined according to handover information in B, base station, and add the miss-configured neighboring cells of determining to second best miss-configured neighboring cells collection;
Among this step B, handover information is this terminal that preserves in advance base station that terminal belonged to is finished operating in soft handover between cell-of-origin and adjacent sub-district a success rate, and the information such as number of times of finishing operating in soft handover, choose the higher miss-configured neighboring cells of described success rate and number of times in the present embodiment and add the second best miss-configured neighboring cells collection to;
C, base station be according to described positional information, determines that the described second best miss-configured neighboring cells concentrate the nearest miss-configured neighboring cells with described cell-of-origin, with these miss-configured neighboring cells as best miss-configured neighboring cells.
Among this step C, can calculate distance between cell-of-origin and the miss-configured neighboring cells by several different methods, specifically can be by the cell-of-origin of base station preservation and the positional information of miss-configured neighboring cells, they be that longitude and latitude information are determined the distance between cell-of-origin and the miss-configured neighboring cells, and the miss-configured neighboring cells that the distance sources sub-district is nearest are as best miss-configured neighboring cells;
In step 25, finally can determine one or more best miss-configured neighboring cells;
Step 26, base station are added the information of described definite one or more best miss-configured neighboring cells in the neighbor cell configuration information table of preserving this base station self;
Step 27, the message of configuration successful is sent to terminal in the base station, and notifies described terminal and described miss-configured neighboring cells to carry out operating in soft handover, can finish the operation of revising miss-configured neighboring cells.
