The method comprises: when mobile station initiates a joint attach request or a route area/location area renewing request, if the MSC/VLR selected by the serving SGSN needs to be transferred to other MSC/VLR due to heavy load or reset, it returns a location renew acceptance message carrying virtual NRI to the serving SGSN; the according to the NRI carried in the location renew acceptance message, the serving SGSN decides if the MS needs to be transferred to other MSC/VLR; the serving SGSN reselects the serving MSC/VLR in node pool, and re-initiates a location renewing request to transfer the MS to other MSC/VLR.

当移动站发起联合附着或路由区/位置区更新请求时，若服务SGSN选择的MSC/VLR因负载过重或重启等原因需要将MS转移到其他MSC/VLR，则向服务SGSN返回携带虚拟NRI的位置更新接受消息；服务SGSN根据接收的位置更新接受消息中携带的虚拟NRI判断需要转移MS到其他MSC/VLR，服务SGSN在节点池中重新选择服务MSC/VLR，重新发起位置更新请求，将MS平滑地转移到其他MSC/VLR进行附着或位置区更新流程。

RSSI-based location is a hotspot in nowadays. This paper presents RSSI-based triangle and centroid location algorithm and trilateration algorithm, and analyses the average positioning error produced by this two methods. Simulation experiments prove that triangle and centroid location algorithm can obviously improve the location accuracy compared to trilateration algorithm.

Common buckwheat ( F. esculentum ) is an allogamy crop, which is heterogony. There is heterogeneity in the species. To reveal the genetic diversity within cultivar population, In order to explore the sampling strategy that can reveal genetic diversity of buckwheat resources on the molecular level. PCR with intron-splice junction primers and long random primers was employed to reveal the genetic diversity within nine common buckwheat varieties and one tartary buckwheat cultivar population among different individuals. We established the sampling strategy in its genetic diversity study. Then we used the established sampling strategy, and the same PCR markers technique,to analysis the genetic diversity of 86 common buckwheat resources, the main results are as follows
