Method for reducing the latency during data transmission in a communication network, communication procedure for user terminal devices in a cellular communication network and cellular communication network

摘要

Method for reducing the latency in data transmission within a cellular communication network (10), especially a mobile radio network, for communication between user terminal devices (13; 14, 15), the communication network (10) a core network (11) and an access network (12) that is concerned with establishing a link between the user terminal devices (13; 14, 15) and the core network (11), characterized by the following steps , performed by the communication network (10): a) reception in the access network (12) information on the user terminal devices (13) comprising at least content data and position data; and B) direct transmission of content data or content data and the position data, at least some terminal devices selected user (14, 15) having a particular spatial relationship with the user terminal device ( 13) sending the information or the information sent by the user terminal device (13) without information is transmitted first to the core network, performing the data transmission from the access network (12) to less to the terminal devices selected user (14, 15) via multicast or broadcast.
