Description
Technical field
The present invention relates to wireless communication technology field, relate in particular to the method for a kind of network side apparatus and updating system information piece SIB thereof.
Background technology
The network optimization is the key link of wireless network construction and development, mainly comprises parameter optimization and neighboring BS relationship optimization etc.In mobile communication system, neighboring BS relationship is one of basic configuration of sub-district, and it is in order to guarantee handover success and cell reselection that the neighboring BS relationship purpose is set.Wherein UE in this Serving cell is given by system information broadcast in the adjacent area of each Serving cell, so that UE realizes sub-district switching and sub-district gravity treatment in the Serving cell.
At present, network side is by definite scheme of the adjacent area of each Serving cell of system information broadcast, a kind of is full static configuration mode, and promptly the adjacent area of each Serving cell pre-sets in the network planning with in optimizing, and is broadcast to UE in each Serving cell by the system information correspondence then.The mode of full static configuration so can not adapt to the variation of network because the neighbor cell configuration of each Serving cell is no longer upgraded after good.
At LTE (Long Term Evolution, Long Term Evolution) in the system, along with SON (Self-OrganizedNetwork, self-organizing network) introducing, ANR (Automatic Neighbor Relation has been proposed at present, the automatic adjacent section discovery) this semi-static configuration mode realizes that the adjacent area is definite, makes eNB (Evolved NodeB, evolution base station) can set up neighboring BS relationship automatically.Existing semi-static configuration mode comprises as shown in Figure 1:
Step S101, UE are according to the designated cell of eNB indication, and the measurement report to the eNB at current place sends the measurement result of carrying designated cell also carries the physical layer identifications phy-CID of designated cell in this measurement report;
Which sub-district UE need measure by eNB and specify.At the network initial stage, the Neighboring Cell List of each Serving cell is empty, and eNB is that UE is given in the corresponding appointment of each Serving cell bigger cell range and indication.
UE measures the designated cell of eNB indication, when satisfying the measurement report condition, the measurement result of designated cell is reported, this measurement result can comprise the signal strength signal intensity such as signal RSRP (the Reference Signal Receiving Power of designated cell, Reference Signal Received Power) and/or RSRQ (Reference Signal Received Quality, Reference Signal Received Quality) etc.
Step S102, eNB is according to the measurement result in the measurement report, at each Serving cell, determine which measurement designated cell satisfies the signal strength signal intensity requirement of the adjacent area that is set to this Serving cell, if the phy-CID that satisfies the designated cell that signal strength signal intensity requires is not when the Neighboring Cell List of current service cell, indication UE obtains the Global-CID of these designated cell;
Which designated cell existing standard determines according to measurement result by pre-defined algorithm can be set to the adjacent area, mainly is to determine with reference to the signal strength signal intensity of designated cell, no longer describes in detail here.The phy-CID that satisfies the designated cell that signal strength signal intensity requires is not at the Neighboring Cell List of current service cell, illustrate that the designated cell that can not be set to the adjacent area adds in the Neighboring Cell List, phy-CID be can distinguishing cell in subrange sign, overall identification Global-CID is the unique sign that can distinguishing cell in the whole world, phy-CID is the brachymemma of Global-CID, uses phy-CID can reduce signaling consumption in the measurement report that UE reports.
Step S103, UE be according to the indication of eNB, and needs are read the designated cell of Global-CID, uses the phy-CID of this designated cell to remove to read its Global-CID, when UE gets access to the Global-CID of these designated cell, it reported eNB.
Step S104, eNB adds the Global-CID of the designated cell that UE reports in the Neighboring Cell List of Serving cell to, thereby has set up the neighboring BS relationship of Serving cell in Neighboring Cell List.
Therefore, the Neighboring Cell List of each Serving cell progressively generates in the above-mentioned semi-static configuration mode, and regularly gives UE with the Neighboring Cell List that generates by system information broadcast.
In the above-mentioned ANR scheme, before UE measures, which sub-district eNB promptly measures must for the UE intended target, only support with frequency and with the measurement of standard at present for the measurement configuration of UE, as for the Serving cell that is operated at least two frequencies, set up corresponding Neighboring Cell List at each frequency, UE can only measure the sub-district identical with its working frequency points, eNB is broadcast to the UE that is operated in this frequency in the Serving cell with the Neighboring Cell List of one of them frequency correspondence, so UE can only switch with neighboring interval frequently.For the Serving cell that can be operated at least two kinds of communication standards, there are 2G, 3G and three kinds of networks of LTE simultaneously as Serving cell, set up corresponding Neighboring Cell List at every kind of standard, the UE that is operated in a certain standard only measures this and is operated in designated cell under this standard, as the UE that is operated in the 3G standard only surveying work in the sub-district of 3G standard, eNB is broadcast to the UE that is operated in this standard in the Serving cell with the Neighboring Cell List of one of them standard correspondence, so UE can only switch at the neighboring interval with standard.So ANR can only be used for the adjacent area that reaches frequently with standard, and can not be used for the different standard of alien frequencies adjacent area, can't realize full-automatic configuration, so be called semi-static configuration.
In current wireless network, network load is difficult to control, to the operator of a plurality of wireless frequencies and standard is arranged, only relies on static configuration and semi-static collocation method, and Radio Resource can't be accomplished sufficient utilization.
