Abstract
Methods, apparatuses and systems are described for conveying location information from an announcing user device to a listening user device engaged in ProSe discovery communications. The announcing user device may use a first expression to broadcast an initial announcement, and then use a second expression to broadcast the location of the announcing user device. The first expression may be in the form of a public expression while the second expression may be in the form of a private expression.
Claims30
A method of wireless communication, comprising:
- broadcasting, from a transmitter of a user device, a first message that comprises a first expression using proximity services (ProSe) discovery communications, the first expression including a first announcement of services, and
- broadcasting, from the transmitter of the user device, a second message that comprises a second expression using ProSe discovery communications, the second expression including location information relating to the user device and being identifiable through use of the first expression, wherein the first expression and the second expression are different.
An apparatus for wireless communication, comprising:
- means for broadcasting, from a transmitter of a user device, a first message that comprises a first expression using proximity services (ProSe) discovery communications, the first expression including a first announcement of services, and
- means for broadcasting, from the transmitter of the user device, a second message that comprises a second expression using ProSe discovery communications, the second expression including location information relating to the user device and being identifiable through use of the first expression, wherein the first expression and the second expression are different.
An apparatus configured for wireless communication, comprising:
- at least one processor;
- and
- a memory coupled to the at least one processor, wherein the at least one processor is configured:
- to broadcast, from a transmitter of a user device, a first message that comprises a first expression using proximity services (ProSe) discovery communications, the first expression including a first announcement of services, and
- to broadcast, from the transmitter of the user device, a second message that comprises a second expression using ProSe discovery communications, the second expression including location information relating to the user device and being identifiable through use of the first expression, wherein the first expression and the second expression are different.
A method of wireless communication, comprising:
- receiving, from a transmitter of a user device, a first message comprising a first expression using proximity services (ProSe) discovery communications, the first expression including an announcement of services;
- receiving, from the transmitter of the user device, a second message comprising a second expression using ProSe discovery communications, the second expression being identifiable through use of the first expression;
- and
- determining a location of the user device from the second expression, wherein the first expression and the second expression are different.
