Method for exploiting signalling messages in a wireless communication network
First Claim
1. A method of exploiting a signaling message related to a predetermined open system interconnect layer of a wireless communication system and configured to transmit signaling information specific to said open system interconnect layer for transmitting data different from said signaling information, comprising:
- ascertaining the presence of unallotted space in said signaling message related to said predetermined open system interconnect layer;
based on the ascertained presence of unallotted space, determining an amount of transmissible data different from said signaling, wherein said transmissible data relates to a second open system interconnect layer different from said predetermined open system interconnect layer; and
modifying the signaling message by filling at least part of the unallotted space with said amount of transmissible data.

Abstract
A method of exploiting a signaling message related to a predetermined OSI layer of a wireless communication system and adapted to transmit signaling information specific of the OSI layer for transmitting data different from the signaling information, includes: ascertaining the presence of unallotted space in the signaling message; based on the ascertained presence of unallotted space, determining an amount of transmissible data different from the signaling information; and modifying the signaling message by filling at least part of the unallotted space with the amount of transmissible data. The method is in particular useful in cellular telephony networks like 2G and 3G networks, in 802.1x networks and broadcasting ones such as DVBs.
