Problems solved by technology

[0008] For services with small data volumes, if the existing trigger mode of buffer status reporting is still used, the buffer status will be reported frequently, and the control overhead and filling overhead when scheduling small data volume services on the network side are relatively large, thereby reducing the uplink Data transfer efficiency

Embodiment 1

[0022] Embodiment 1 of the present invention provides a method for reporting cache status. By comprehensively considering the buffer data volume and cache waiting time of terminal equipment, it solves the problem of frequent reporting of terminal equipment cache status for small data volume services in power communication systems and other systems. , the problem of increasing system overhead.

[0023] Such as figure 1 As shown, the method for reporting the cache status includes the following steps:

[0024] Step 101, the terminal device determines the amount of buffered data and / or the waiting time for buffering.

[0025] In step 102, the terminal device reports the cache status (that is, triggers a BSR report) according to the cached data volume and / or the cache waiting time.

[0026] Method 1: The terminal device determines the cached data volume, and reports the cached status according to the cached data volume.

[0027] Specifically, the terminal device monitors its own...

Embodiment 2

[0045] Based on the same inventive concept as the above method, an embodiment of the present invention also provides a terminal device, such as figure 2 As shown, the equipment includes:

[0046] Determining module 11, is used for determining cache data amount and / or cache waiting time;

[0047] The sending module 12 is configured to report the cache status according to the cache data amount and / or cache waiting time.

[0048] The sending module 12 is specifically configured to report the cache status when the buffer data volume is greater than a preset data volume threshold; or, when the cache waiting time is greater than a preset time threshold, report the cache status; or, according to the Report the cache status according to the amount of cached data and the cache waiting time.

[0049] In the embodiment of the present invention, the sending module 12 includes:

[0050] Judging sub-module 121, used to judge whether the cached data volume is greater than the preset data...

Abstract

The invention discloses a cache state reporting method and equipment. The method comprises the following steps that: terminal equipment determines the cache data quantity and/or cache waiting time; and the terminal equipment reports the cache state according to the cache data quantity and/or cache waiting time. In the embodiment of the invention, by comprehensively considering the cache data quantity and/or cache waiting time of the terminal equipment and determining when to report the cache state according to the cache data quantity and/or cache waiting time, the occupation overhead is reduced (namely that the uplink overhead resulting from frequent reporting can be reduced), and the transmission efficiency of uplink data is effectively improved.

Description

technical field [0001] The present invention relates to the technical field of communications, in particular to a method and device for reporting a cache state. Background technique [0002] An important direction of the Internet of Things technology is the smart grid. The smart grid uses advanced information technology, new materials and new devices, energy storage technology, new grid structure and new power transmission and distribution methods to operate and manage the grid, so that the grid It can accommodate the large-scale access of new energy, realize the optimal allocation of energy resources, and make the power grid more efficient, clean, safe and reliable. The smart grid is the main body of future energy production, transmission, distribution and utilization, and the future energy system and smart grid will be highly integrated. In addition, the transmission of the power grid is completed through optical fibers, and power distribution and control can be completed...
