Embodiment Construction

[0033] In the following, concepts according to embodiments of the present invention will be explained in more detail with reference to the accompanying drawings. The illustrated concept involves geographically targeted distribution of messages of an application service via correspondingly configured servers and ad-hoc network connections to clients typically located in vehicles. Additionally, an Internet Protocol (IP) based network connection to the client may also be utilized. In the example shown, it is assumed that the IP-based network connection is a cellular network connection. However, it is to be understood that the IP-based connection could also be another wireless connection or a wired connection. Ad hoc network connections may be based on IEEE802.11p or ITS-G5 radio technology, for example. A cellular network connection may eg be provided by a 3GPP network eg using LTE radio access technology. However, it should be understood that other cellular network technologi...

Abstract

Interworking for geographically targeted distribution of application service messages via ad-hoc network A distribution server (200) for geographically targeted message distribution to a client (110) is used for is providing an application service, in particular a vehicular traffic related application service, such as a Cooperative Intelligent Transport System (C-ITS)service. An interworking device (100) connects, e.g., via a cellular network connection (40), to the distribution server (200). Further, the interworking device (100) connects via an ad-hoc network connection (50) to the client (110). On behalf of the client (110), the interworking device performs registration for the application service at the distribution server (200). On the basis of the registration, the interworking device (100) forwards at least one message of the application service between the distribution server and the client (110).

Description

technical field [0001] The present invention relates to a method and a corresponding arrangement for geographically targeted distribution of application service messages via an ad-hoc network. Background technique [0002] In the context of a Collaborative Intelligent Transport System (C-ITS) application, ETSITS 103084 V0.0.3 "Geo-Message Enabler" proposes the use of a geo-targeted distribution mechanism called Geo-Message (GM). As described in "An Optimized Grid-Based Geocasting Method for Cellular Mobile Networks" by G. Jodlauk et al., ITS World Congress 2011, Orlando, USA, October 2011 and in WO2012 / 055433A1, this concept involves a GM tracking the position of a GM client using a grid-based scheme. server. A GM client notifies the GM server when it moves to another domain of the grid, which allows the GM server to continuously update the GM client-to-grid region mapping. Based on this mapping, the GM server can serve the distribution requests of different application se...
