Abstract
A communication system including a first and second user equipment in communication over a shared floor and a server means for managing the shared floor. According to the system, the server means is arranged to detect an anonymity request from the first user equipment and, responsive to the anonymity request, to prevent the second user equipment from identifying the first user equipment from user plane messages transmitted from the first user equipment to the second user equipment.
Claims27
An apparatus comprising a server configured to:
- detect an anonymity request for a first user equipment, wherein the first user equipment is in communication with a second user equipment over a shared floor;
- and
- responsive to said anonymity request, prevent the second user equipment from identifying the first user equipment from at least one user plane message transmitted from the first user equipment to the second user equipment by removing the identification of the first user equipment from the at least one user plane message, the at least one user plane message comprising a unique anonymous token, the unique anonymous token linking the at least one user plane message to the first user equipment to enable another equipment different from the first user equipment and the second user equipment to link the at least one message to the first user equipment based on the anonymous token, while preventing the second user equipment from identifying the first user equipment based on the anonymous token;
- wherein the server is in communication with a controlling server to control access to the shared floor, and further configured to receive from the controlling server the at least one user plane message including shared floor access control signals, the anonymity request for the first user and the identification of the first user equipment.

A method comprising:
- receiving a request for anonymity from a first user equipment, wherein the first user equipment and a second user equipment are in communication over a shared floor;
- preventing the second user equipment from identifying the first user equipment from at least one user plane message transmitted from the first user equipment to the second user equipment by removing, at a server serving the second user equipment, the identification of the first user equipment from the at least one user plane message, wherein the at least one user plane message comprises a unique anonymous token, the unique anonymous token linking the at least one user plane message to the first user equipment to enable another equipment different from the first user equipment and the second user equipment to link the at least one message to the first user equipment based on the anonymous token, while preventing the second user equipment from identifying the first user equipment based on the anonymous token;
- wherein the server serving the second user equipment is in communication with a controlling server to control access to the shared floor, and further configured to receive from the controlling server the at least one user plane message including shared floor access control signals, the anonymity request for the first user and the identification of the first user equipment.
A system, comprising:
- a first and second user equipment in communication over a shared floor;
- a controlling server configured to manage the shared floor;
- and
- at least one participating server configured to serve said second user equipment,
- wherein the controlling server is configured to detect an anonymity request from the first user equipment, to insert into user plane messages from the first user equipment a privacy indication and, wherein the at least one participating server is further configured, responsive to said privacy indication, to prevent the second user equipment from identifying the first user equipment by removing an identification of the first user equipment from said user plane messages, wherein the user plane messages comprise a unique anonymous token, the unique anonymous token linking the user plane messages to the first user equipment to enable another equipment different from the first user equipment and the second user equipment to link the user plane messages to the first user equipment based on the anonymous token, while preventing the second user equipment from identifying the first user equipment based on the anonymous token;
- wherein the at least one participating server is in communication with the controlling server, the controlling server further configured to forward to the at least one participating server the user plane messages, at least one of the user plane messages including shared floor access control signals, the privacy indication and the identification of the first user equipment.
3 more elements
An apparatus, comprising:
- detecting means for detecting an anonymity request from a first user equipment, wherein the first user equipment is in communication with a second user equipment over a shared floor;
- and
- responsive to said anonymity request, preventing means for preventing the second user equipment from identifying the first user equipment from at least one user plane message transmitted from the first user equipment to the second user equipment by removing an identification of the first user equipment from said at least one user plane message, wherein the at least one user plane message comprises a unique anonymous token, the unique anonymous token linking the at least one user plane message to the first user equipment to enable another equipment different from the first user equipment and the second user equipment to link the at least one message to the first user equipment based on the anonymous token, while preventing the second user equipment from identifying the first user equipment based on the anonymous token;
- wherein the detecting means is in communication with a controlling server to control access to the shared floor, and further configured to receive from the controlling server the at least one user plane message including shared floor access control signals, the anonymity request for the first user and the identification of the first user equipment.
1 more element
A computing-based device comprising a server configured to perform:
- receiving a request for anonymity from a first user equipment, wherein the first user equipment and a second user equipment are in communication over a shared floor;
- and
- preventing the second user equipment from identifying the first user equipment from at least one user plane message transmitted from the first user equipment to the second user equipment by removing the identification of the first user equipment from the at least one user plane message, wherein the at least one user plane message comprises an anonymous token, the unique anonymous token linking the at least one user plane message to the first user equipment to enable another equipment different from the first user equipment and the second user equipment to link the at least one message to the first user equipment based on the anonymous token, while preventing the second user equipment from identifying the first user equipment based on the anonymous token;
- wherein the server serving the second user equipment is in communication with a controlling server to control access to the shared floor, and further configured to receive from the controlling server the at least one user plane message including shared floor access control signals, the request for anonymity from the first user equipment and the identification of the first user equipment.
