Embodiment
With reference to accompanying drawing, specify embodiment of the present invention below.
With reference to figure 2, the neighbor section list updating method according to the embodiment of the invention is described.As shown in Figure 3, this neighbor section list updating method may further comprise the steps:
S202, its next sub-district cisco unity malfunction (damaging like hardware resource) is found in base station 1, sends exception reporting for the MANET server at once, is with cell id in the report;
S204, there is the base station of neighbor cell MANET server retrieves and this base station 1, and these base stations under the management of this MANET server, are base station 2 among this embodiment all;
S206, MANET server send out abutting subdistrict and change notice to base station 2, carry unusual basic station number and cell id in the notice;
S208, notified base station 2 is then carried out the automatic adjacent section search procedure one time according to the sub-district in unusual basic station number and the cell id deletion Neighboring Cell List, if this cell id not in Neighboring Cell List, then need not carried out adjacent area search and following step;
S210, the basic station number that cell neighboring relation is arranged that base station 2 will be upgraded reports the MANET server through update notification, and the MANET server update safeguards that there is relation in the adjacent area between each base station.
With reference to figure 3, neighbor section list updating method according to another embodiment of the present invention is described.As shown in Figure 3, this neighbor section list updating method may further comprise the steps: S302, and base station 1 is suddenly down; Send exception reporting for the MANET server; The MANET server detects the link down with this base station 1, thinks that this base station 1 is unusual, and there is the base station of neighbor cell MANET server retrieves and this base station 1; These base stations under the management of this MANET server, are base station 2 among this embodiment all; S304, MANET server send out abutting subdistrict and change notice to relevant base station 2, are with unusual basic station number in the notice; S306, notified base station 2 is then carried out the automatic adjacent section search procedure one time according to the respective cell in the unusual basic station number deletion Neighboring Cell List; S308, the basic station number that cell neighboring relation is arranged that base station 2 will be upgraded reports the MANET server through update notification, and the MANET server update safeguards that there is relation in the adjacent area between each base station.
That is to say; In Fig. 2 and neighbor section list updating method shown in Figure 3, at first, base station unusual or that close takes place send message and give the MANET server; Perhaps can not send under the situation of message in the base station fault, it is unusual that the MANET server detects the base station through link layer; Then; The MANET server retrieves has cell neighboring relation with unusual base station, and (this relation table is issued server by the base station when accomplishing each adjacent-area list renewing; As shown in Figure 4) the base station; Send abnormity notifying message and give these base stations, if between the base station of different MANET server admins, neighboring BS relationship is arranged, then through server forwards message; Then; Delete the sub-district of unusual base station notified base station from Neighboring Cell List; And then carry out automatic adjacent section search procedure (according to the measurement at self or terminal); With the adjacent area that determines whether other get into tabulation (such as do not get into because signal is bad relatively original Neighboring Cell List the sub-district, or the sub-district of adjustment coverage automatically); At last, the Neighboring Cell List after these base stations will be upgraded automatically sends to the MANET server.
In sum, the present invention has realized the Unified Treatment for various abnormal conditions (comprise the sub-district is unusual, the sub-district is closed, the base station unusual, the base station is closed and base station power-down etc.).Mode is simple, quick, can report for the base station, just reported by the base station, in time to handle; Can not report for the base station, detected by the MANET server, the detection of link layer also can realize more ageing than higher.
In addition, the fusion that the present invention has realized and Neighboring Cell List automatically upgrades exists as a kind of triggering of Neighboring Cell List search, has embodied the integrality of automatic adjacent section prioritization scheme.Simultaneously, because the neighbouring relations of the base station level of MANET server maintenance make that the MANET server only needs to send message to relevant base station, and do not need to all base station mass-sendings, therefore avoided overhead.
The above is merely embodiments of the invention, is not limited to the present invention, and for a person skilled in the art, the present invention can have various changes and variation.All within spirit of the present invention and principle, any modification of being done, be equal to replacement, improvement etc., all should be included within the claim scope of the present invention.
