Description
Technical field
The present invention relates to the communications field, particularly a kind of renewal neighbouring areas list method, system and relevant device.
Background technology
In wireless communication system, not only have to solve the wide macro base station (macro cell) that covers and solve the microcellulor (micro cell) that the intensive hot zones of telephone traffic/throughput covers, also have the littler femto base station of coverage, as: femto cell.Such femto base station is mainly used in family, certainly also applicable to school, market, office building and other places.The up IP network that is linked into; The descending air protocol of following standard is such as the air interface agreement of supporting CDMA2000 1X (getting involved the CDMA communication technology between the second generation and the third generation) or CDMA2000 1X EVDO (the CDMA communication technology of enhancement mode) etc.With home-use femto cell is example: a femto cell generally only supports several mandate portable terminals, and unauthorized portable terminal can not use femto cell.Therefore,, when idle condition, between macro base station and femto cell, normal gravity treatment can be realized, when connection status, between macro base station and femto cell, two-way normal switching can be realized for the mandate portable terminal of femto cell.
No matter be to carry out gravity treatment or switching, portable terminal all need obtain the Neighboring Cell List that the base station issues in advance, and is kept in the portable terminal.When idle condition, portable terminal resides in certain sub-district, and according to the signal strength signal intensity of each adjacent area of the Neighboring Cell List of this sub-district search, and safeguards Active Set according to self-defining algorithm.When connection status; Portable terminal provides service by certain sub-district; And according to the signal strength signal intensity of each adjacent area of the Neighboring Cell List of this sub-district search; Give base station controller through pilot measurement reports message with information reporting such as the cell identification that records number and signal strength signal intensities, base station controller is safeguarded Active Set according to self-defining algorithm, and the situation of Active Set is informed portable terminal.
All there is own exclusive Neighboring Cell List each sub-district.This tabulation is at the networking initial stage, and the engineering staff is according to the neighboring BS relationship of network topology situation and the planning of drive test situation.The general paired appearance of neighboring BS relationship under special circumstances, also unidirectional adjacent area can occur.A Neighboring Cell List comprises the essential information of a main plot and a plurality of adjacent sub-districts.Therefore the neighboring BS relationship of A and B means that with A to be the main plot be the Neighboring Cell List of adjacent sub-district and be that the main plot is the Neighboring Cell List of adjacent sub-district with A with B with B.Neighboring Cell List is general to adopt manual mode to be arranged in the database, is issued to each sub-district of each base station then respectively through Operation and maintenance link, and Neighboring Cell List will be preserved in the base station.When the network commencement of commercial operation, down-sending neighbor list is given each portable terminal of idle condition and connection status in the sub-district.
Therefore, Femto cell is as a kind of slight little base station of family expenses.When the user buys; Network side can't know/confirm the user use Femto cell definite position and and contiguous macro base station/microcellulor/femto base station between relative position; Therefore create Neighboring Cell List can't for Femto cell, add the Neighboring Cell List that comprises Femto cell also can't for contiguous sub-district.In order to create Neighboring Cell List for Femto cell and to add Neighboring Cell List for the contiguous sub-district of Femto cell.
Prior art provides a kind of technical scheme, and is as shown in Figure 1, comprises step:
101, the coverage condition of the base station of Femto cell searching near and solve the signal of these each sub-districts, base station mainly is Cell Identity CI, network code etc.;
102, detected Cell Identity CI is deposited in the data structure;
103, the signal of each sub-district is measured, and after adding in the data structure measurement result to corresponding cell ID;
104, report the data structure that records to give base station controller;
105, base station controller is according to the data that report; According to self-defining algorithm, data are carried out interpolation, filtering and reduction, obtain some suitable adjacent area data; And use one of these data creation to be the main plot with Femto cell, contiguous sub-district is the Neighboring Cell List of adjacent sub-district;
106, this Neighboring Cell List is sent to Femto cell;
107, this Femto cell preserves this Neighboring Cell List;
108, Femto cell sends to portable terminal through air interface with Neighboring Cell List.
There are two shortcomings in this technical scheme: the first, base station controller is when creating Neighboring Cell List; Only created with Femto cell and be the main plot, be the Neighboring Cell List of adjacent sub-district with its contiguous sub-district; Be the main plot, newly be added into the Neighboring Cell List of the adjacent sub-district that comprises Femto cell and create respectively, the candidate cell that is not easy to like this that portable terminal is monitored easily and switches when gravity treatment and connected state when selecting Femto cell when adjacent cell as the free time with each contiguous sub-district.The second, base station controller is the main plot, adds Femto cell when being the Neighboring Cell List of adjacent sub-district creating with contiguous base station; Because the up-downgoing frequency of FDD system is different; Therefore the loss situation of uplink downlink is not quite similar, and the situation of the sub-district of the vicinity that therefore detects with Femto cell in the prior art is the main plot, is that the neighbouring areas list method of adjacent sub-district is inaccurate with contiguous sub-district as creating with Femto cell.
