Technical field
The present invention relates to communication field, relate in particular to a kind of T_cell parameter distribution method that improves the wireless access network net synchronization capability.
Background technology
Usually wireless access network is when setting up link, user terminal (User Equipment, UE) basis of setting up contact with base station (NodeB) be UE from NodeB, obtain synchronizing channel (SynchChannel, SCH).Because the quality of net synchronization capability directly affects performances such as network servicequality, switching and location, so UE does not wish to receive simultaneously the SCH of different districts.The 3GPP agreement stipulates that each sub-district of same NodeB is at the base station of antenna opening frame number (NodeB Frame Number for this reason, BFN) certain T_cell behind the timing reference point (time differences between BFN timing and the SFN data) begins emission system frame number (System Frame Number, SFN) data (being the data of relevant physical channel and sub-district synchronous channel SCH) constantly.
The T_cell parameter is that (NodeB Application Part NBAP) obtains in the message base station application part of sending here from base station controller (RNC) when setting up in the sub-district, and the different districts in the same adjacent area distributes different T_cell values.All sub-districts have only unique base station frame number (BFN) for timing reference in the common NodeB, between the SFN data of the BFN of antenna opening timing and emission, keep the sequential relationship of certain intervals T_cell as long as therefore can guarantee each sub-district, the UE that just can guarantee to stagger receives the time of each SCH of this sub-district, thus do not influence between UE and the NodeB synchronously.
Yet, can't guarantee fully that at present each sub-district keeps the sequential relationship of certain intervals T_cell between antenna opening BFN timing and emission SFN data, this is because the different districts signal may be walked different radio-frequency channels, radio-frequency devices discreteness and signal transmission path difference or the like.The different situation of schematic diagram brief description signal transmission path of communicating by letter with NodeB below in conjunction with UE, as shown in Figure 1, the possible communication mode of UE and NodeB comprises between the different base station, each Remote Radio Unit (Remote Radio frequency Unit of same base station different districts and different distributions formula base station, RRU) the multiple combination between this shows that UE is not the same with the signal transmission path of each sub-district that may communicate by letter with it.The difference of transmission path will cause the propagation delay time difference of the SCH that launches on the distinct device, if the time (being the configuration of T_cell) of the SFN data of each equipment emission is not controlled, UE may receive a plurality of SCH channels simultaneously, that is to say, may there be to a certain degree overlapping in the SCH that UE receives same base station neighbor cell, the SCH that UE receives different base station (comprising RRU) emission in overlapping covering place of different base station will exist more overlapping, therefore can there be the phase mutual interference between different SCH, thereby can influence the reception of SCH, reduce the net synchronization capability of network.
In addition, when not considering the utilization distributed base station in the prior art at present, under each RRU and RRU cascade situation, how to guarantee the sequential relationship of antenna opening.Therefore press for a kind of T_cell parameter distribution method of optimization, to improve the net synchronization capability of wireless access network.
