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 first embodiment of the invention is described.As shown in Figure 2, 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 (carrying the cell id of the unusual sub-district of cisco unity malfunction in the report) for association base station 2, after association base station 2 receives exception reporting at once; Suppressing exception sub-district from Neighboring Cell List; Simultaneously and since base station 1 also work, so it also will carry out the operation of following association base station.
S204, association base station 2 then carry out the automatic adjacent section search procedure one time, with the sub-district of the new base station of the Neighboring Cell List that determines whether to get into association base station 2 and/or leave last sub-district of unusual base station of the Neighboring Cell List of association base station 2.Wherein, If the cell id of the unusual sub-district among the step S202 (that is to say other sub-districts that take place under the unusual base station are arranged in the Neighboring Cell List not in the Neighboring Cell List of association base station 2; If be described to cell level rather than base station rank to the opposite end syntople; Can avoid this situation, but can increase some complexities), then need not carry out adjacent area search and following step.
S206; If association base station 2 finds to have first sub-district under the base station 3 to get into its Neighboring Cell List; Then send message to base station 3, in opposite end adjacency table is listed it in request base station 3, if association base station 2 finds have last sub-district under the base station 1 to leave its Neighboring Cell List; Then send message to base station 1, the opposite end adjacency table is shifted out with it in request the other side base station 1.
With reference to figure 3, the neighbor section list updating method according to second embodiment of the invention is described.As shown in Figure 3, this neighbor section list updating method may further comprise the steps:
S302, base station 1 is electric down suddenly, sends exception reportings for association base station 2; The mode that association base station 2 detects through link layer detects the link down with base station 1; Think that base station 1 is unusual,, then delete it if in the opposite end adjacency table of association base station 2 base station 1 is arranged; If the sub-district (explanation is the association base station of unusual base station) under the base station 1 is arranged in the local terminal abutting subdistrict of association base station 2, then deletes it.
S304, association base station 2 then carry out the automatic adjacent section search procedure one time, with the sub-district of the new base station of the Neighboring Cell List that determines whether to get into association base station 2 and/or leave last sub-district of other base stations of the Neighboring Cell List of association base station 2.
S306; If association base station 2 finds to have first sub-district under the base station 3 to get into its Neighboring Cell List; Then send message to base station 3, in opposite end adjacency table is listed it in request the other side base station 3, if there is last sub-district under other base stations to leave its Neighboring Cell List; Then send message to these other base stations, request the other side shifts out the opposite end adjacency table with it in the base station.
That is to say; Base station unusual or that close takes place sends the base station that message is given has the opposite end neighboring BS relationship and (refers to that the base station, opposite end listed the sub-district under this base station in its Neighboring Cell List; Be called association base station); Perhaps can not send under the situation of message in the base station fault, it is unusual that association base station detects the base station through link layer; Association base station is deleted the sub-district of unusual base station from Neighboring Cell List; And then carry out automatic adjacent section search procedure (according to the measurement at self or terminal); The adjacent area that is used to determine whether other get into tabulation (such as do not get into the sub-district of original Neighboring Cell List because signal is bad relatively or adjust the sub-district of coverage automatically); And association base station sends message to base station newly-increased or that deleted the place, adjacent area, requires the other side with its adding or shift out the opposite end adjacency table.Wherein, the content of opposite end adjacency table and form are as shown in Figure 4.In opposite end adjacency table shown in Figure 4, " 1 " expression the other side has listed the sub-district under this base station in adjacent area in the base station, and " 0 " expression does not have.The opposite end adjacency table is different with the local terminal Neighboring Cell List, and neighboring BS relationship possibly be asymmetric (that is, base station 1 is not listed the sub-district of base station 2 in its adjacent area, and base station 2 is listed the sub-district of base station 1 in its adjacent area), and syntople is symmetrical.
Can find out that from above description neighbor section list updating method according to the present invention has been 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, base station power-down etc.).Mode is simple, quick, can report for unusual base station, just reported by unusual base station, and in time handles; Can not notify for unusual base station, detected by the base station, opposite end, the detection of link layer also can realize more ageing than higher.
In addition, the fusion that neighbor section list updating method according to the present invention has been 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; The opposite end neighboring BS relationship of the base station level that preserve each base station; Take place only to send message when unusual, rather than send, avoided overhead to all base stations to the base station that the opposite end neighboring BS relationship is arranged; Neither send message to the affiliated base station of local terminal neighboring BS relationship, avoid the omission that causes because of asymmetric neighboring BS relationship.
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.
