Transmitting data to a group of receiving devices
First Claim
1. A method, comprising:
- defining, by an application server situated beyond a cellular network, a group of communication devices in the cellular network to receive data from the application server via a broadcast/multicast service, the application server having no visibility to locations of receiving devices in the cellular network;
sending a request message, by the application server to a broadcast/multicast network entity, to reserve resources for broadcast/multicast data transmission to the group of communication devices, the broadcast/multicast network entity configured to provide broadcast and multicast services in the cellular network; and
sending the data, by the application server to the broadcast/multicast network entity, for broadcast/multicast transmission to the group of communication devices.

Abstract
A data transmission method transmits data to a group of receiving communication devices in a communication system comprising at least one cellular network. The method includes defining, by an application server situated beyond a cellular network, a group of receiving communication devices in the cellular network, the application server having no visibility to locations of receiving devices in the cellular network. The method also includes receiving, in a broadcast/multicast network entity configured to provide broadcast and multicast services in the cellular network, data to be transmitted from the application server to the group. The method also includes transmitting the data from the broadcast/multicast network entity to the group using broadcast and/or multicast transmission. Furthermore, a network entity in a cellular network and a communication system are provided configured to implement the method.
