Unified header design for discovery messages

摘要

Embodiments are directed to systems, methods and computer program products for enhancing proximity service (ProSe) device to device (D2D) discovery. Embodiments build a discovery message configured for communication over the MAC sub-layer; wherein the discovery message comprises a unified header comprising at least one of a priority level indicator for indicating a priority level of the discovery message; a security existence indicator for indicating whether the discovery message is at least partially encrypted; a type indicator for indicating a discovery message type; and/or an SDU presence indicator (S_ind) for indicating whether the discovery message includes an SDU.

主权项

1. A method for enhancing proximity service (ProSe) device to device (D2D) discovery over a data communication protocol data link layer or sub-layer of a computer networking model, the method comprising:
building, by a user device, a discovery message configured for communication over the data communication protocol data link layer or sub-layer; wherein the discovery message comprises a unified header comprising:
a security existence indicator for indicating whether the discovery message is at least partially encrypted, wherein the security existence indicator is disposed in one or more reserved bits in an LCID (logical channel identifier) byte of the unified header; andat least of:a priority level indicator for indicating a priority level of the discovery message, wherein the priority level defines the quality of service (QoS) level for processing the discovery message; anda type indicator for indicating a discovery message type.
