Benefits of technology

"The patent describes a method for transmitting user data messages from a radio communication system to subscriber devices. The method includes announcing the form of the user data messages before they are transmitted. This allows the subscriber devices to decide whether they can process the user data messages before they are actually received. This saves resources and energy on the subscriber devices. The method can be carried out in the context of a broadcast service, such as a Cell Broadcast Service or a multicast service. The subscriber devices can analyze the planning information and decide to receive only those user data messages that they are capable of processing. This reduces the processing effort and energy consumption in the subscriber devices. The patent also describes a mobile radio device, such as a mobile phone, that can be used as a subscriber device. The patent also describes a radio communication system that can carry out the method. The technical effects of the patent include improved efficiency in transmitting user data messages and reduced energy consumption."

Problems solved by technology

Although this technique is easy to implement, it is unsuitable for large groups.
A problem may arise here, however, in that not all data types of transmitted multimedia messages can be processed by every subscriber device.
In such a case, energy is wasted for no purpose and the service life of the subscriber device is reduced.

Embodiment Construction

[0025]FIG. 1 shows an exemplary schematic illustration of two radio cells CE1, CE2 of a radio communication system FCS which is operated, in particular, according to the UMTS (Universal Mobile Telecommunications System) standard. In terms of radio functionality, the radio cell CE1 is covered by the base station BS1 in this case, while the second radio cell CE2 is supplied by the base station BS2. These two base stations BS1, BS2 are representative of a multiplicity of further base stations of the radio communication system FCS, which further base stations are not illustrated in FIG. 1 but include and cover the corresponding radio cells. The relevant base station is preferably formed by at least one radio transmitter and at least one radio receiver. It preferably has at least one transmitter antenna. In addition to or independently of its function of providing a radio connection to subscriber devices of the radio communication system FCS, the relevant base station can be responsible ...

Abstract

A method is provided for transmitting user data messages from a network element of a radio communication system via at least one transmission channel to at least one subscriber terminal of the radio communication system, whereby the form of the user data messages is announced before the transmission thereof via planning information. The planning information includes a first planning message by which the transmission of the user data messages is announced via a first separate transmission channel, and a second planning message by which description information is transmitted via at least one second transmission channel, the description information indicating the form of the user data messages to be transmitted. The form of the user data messages to be transmitted can include the data type and / or the codification of the user data messages. Announcing the form of the user data messages in the planning information enables the subscriber terminal to only intercept or receive the user data messages that it can actually process, thus enabling energy to be saved during reception and processing.

Description

BACKGROUND OF THE INVENTION [0001] The present invention relates to a method for transmitting user data messages, from a sender to one or more recipients, a subscriber device and a radio communication system. [0002] In the case of many services and applications which are offered in modem mobile radio systems, messages must be transmitted to not just one subscriber, but to two or more subscribers. Such services and applications include, for example, news groups, video conferences, video on demand, distributed applications, etc. [0003] When transmitting the messages to the different subscribers, it is possible to send a copy of the data to each recipient separately. Although this technique is easy to implement, it is unsuitable for large groups. Because the same message is transmitted over N individual connections or unicast connections (N corresponds to the number of recipients) and is therefore sent multiple times over shared connection paths, this method requiring a very high bandw...
