LCS (location services) [3GPP, "Digital cellular telecommunications system (Phase 2+); Functional stage 2 description of Location Services (LCS) in GERAN," Technical Specification, ETSI TS 143 059 v5.3.0 (2002-04).] is a service concept in GSM and UMTS and specifies the network entities and elements that are necessary so that the cellular networks can support positioning functionalities. Broadband wireless access systems provide a mobile terminal with wireless access to a fixed infrastructure from a usually fragmentary coverage. Media point [B. Walke, 2002-04], [G. Plitsis et al., 2002] is a service concept, which enhances the capabilities of the broadband wireless access systems in combination with a 2G or 3G system. This paper analyzes the way the location information of the LCS feature of GERAN could be used in order to push and cache personalized data to the media point component that is nearest to the mobile terminal before it reaches the coverage area of a media point. In this proactive way, the mobile user whenever inside the coverage area, will not need to wait for his or her data (e.g. e-mails) to be downloaded all the way from the Internet and thus increase the efficiency of the media point system.
