Efficient proximity service discovery resource report and allocation

摘要

Effective proximity service discovery resource reporting and allocation. Embodiments of the invention relate to a method for enhancing proximity service (ProSe) device to device discovery resource allocation, the method comprising: allocating, by a network processing device, network resources to a plurality of user devices including at least one user device in a connected mode and at least one user device in an idle mode, the allocating comprising: restricting network resources allocated to the user device in the idle mode for proximity service discovery compared to the network resources allocated to the user device in the connected mode for proximity service discovery, such that the network resources maintain reliable discovery services for the user device in the connected mode as well as provide acceptable discovery services for the user device in the idle mode.

1. A method for enhancing proximity service (ProSe) device to device discovery resource allocation, the method comprising:
receiving a discovery resource status report from a user device; determining that there is a user device in an idle mode which has experienced discovery transmission failure based on the discovery resource status report; allocating, by a network processing device, network resources to a plurality of user devices including at least one user device in a connected mode and the user device in the idle mode, the allocating comprising:
restricting network resources allocated to the user device in the idle mode for proximity service discovery compared to the network resources allocated to the user device in the connected mode for proximity service discovery, such that the network resources maintain reliable discovery services for the user device in the connected mode as well as provide acceptable discovery services for the user device in the idle mode, wherein restricting includes setting a first discovery offset for the user device in the idle mode to be greater than a second discovery offset for the user device in the connected mode for subsequent discovery transmissions, wherein setting comprises:
randomly generating a first random number within a range from a first value (a) to a second value (b) as the second discovery offset, andrandomly generating a second random number within a range from the first value (a) to a third value (c) as the first discovery offset,wherein the third value (c) is greater than the second value (b), or the third value (c) is n times that of the second value (b), where n is an integer greater than 1.
