    • A solution, in particular in multi- vendor situations, allowing access to a mobile location center, for example having capability for specific positioning methods such as fingerprinting, with minor impact on existing standards. The method and system for determining a position of a UE comprises the steps of a first network node receiving a request for positioning information about the UE; the first network node requesting a first positioning procedure at a first location node; the first location node determining using the first positioning procedure that involvement by a second location node is needed; the first location node initiating a trigger for positioning information about the UE to be sent to the second location node; the second location node, upon receiving the trigger for positioning information and determining the presence of an environment measurement parameter, determining the position information of the UE by performing a second positioning procedure based on the environment measurement parameter, and sending a position calculation response with the positioning information.

    • The present invention relates to positioning in a communication network. In Long Term Evolution, LTE networks the positioning server E-SLMC needs routing information in order to communicate with individual base stations, eNodeBs. For LTE networks configured with one Mobility Management Entity, MME or one pool of MMEs, the routing information can be obtained by interrogating the MME or an arbitrary MME in the MME pool. However, if the network is configured with several MME pools serving different sets of eNodeBs, the E- SLMC has now knowledge of which MME or MME pool that is serving a certain eNodeB. The invention includes a method and a position server (111) configured to quickly determine which MME pool (120,130) is serving a certain eNodeB (141-153) so that the relevant routing information necessary for the positioning server (111) to communicate with the eNodeBs (141-153) is obtained.
    • 本发明涉及通信网络中的定位。 在长期演进中,LTE网络定位服务器E-SLMC需要路由信息,以便与各个基站,eNodeB进行通信。 对于配置有一个移动性管理实体,MME或一个MME池的LTE网络,可以通过询问MME或MME池中的任意MME来获得路由信息。 然而,如果网络配置有服务不同组的eNodeB的几个MME池,则E- SLMC现在已经知道为某个eNodeB服务的哪个MME或MME池。 本发明包括一种方法和位置服务器(111),其被配置为快速确定哪个MME池(120,130)服务于某个eNodeB(141-153),使得定位服务器(111)所需的相关路由信息与 获得eNodeB(141-153)。

    • The present invention relates to a system and method for reducing image artifacts for a CMOS camera used as an optical detector for a line confocal fluorescent imager. The method for reducing image artifacts in a monochromatic image comprises subtracting RGB channel offset mismatch; and correcting random row offset for each row. Preferably, the method also comprises correcting random column offset and gain. Optionally, the method also comprises clipping of defective pixels, and/or subtracting dark current. When the monochromatic image is a fluorescence image, the method also comprises a step of compressing CMOS camera noise. Also provided are a system for reducing image artifacts in a monochromatic image from a CMOS camera, as well as an image artifact reduction system for a CMOS camera-based line confocal fluorescent microscope.
