Method for controlling open/sleep state of small base station in heterogeneous network based on double thresholds

Abstract

The invention discloses a method for controlling an open / sleep state of an SBS in a heterogeneous network based on double thresholds. The method for controlling the open / sleep state of the SBS in the heterogeneous network based on the double thresholds comprises the following steps that the SBS detects load values in a covering range of the SBS; according to an upper threshold value and a lower threshold value which are set aiming at the current SBS, the following judgment is performed: when the current SBS is in the sleep state, if a corresponding load value exceeds the upper threshold value, the current SBS is started, and if the corresponding load value does not exceed the upper threshold value, the current SBS keeps in the sleep state; when the SBS is in the open state, if the corresponding load value is less than the lower threshold value, the current SBS is closed, and if the corresponding load value is not less than the lower threshold value, the SBS keeps in the open state. The method for controlling the open / sleep state of the SBS in the heterogeneous network based on the double thresholds can automatically close the SBS of which the load value is small or with no load, and the energy consumption of the heterogeneous network is reduced. The upper threshold and the lower threshold are adopted to control and a certain interval exists between the upper threshold and the lower threshold, so that the switching probability between the open state and the sleep state of the SBS is reduced, signaling overheads are reduced, and the communication quality of users is improved.

Description

technical field [0001] The invention relates to the communication field, in particular to a method for controlling the start-up and sleep states of a small base station in a heterogeneous network. Background technique [0002] With the rapid development of wireless communication systems, the existing single network system can no longer meet the communication requirements of high speed, large capacity, and high quality of service. The next generation of wireless communication technology is developing towards the heterogeneous integration of multiple wireless networks. Heterogeneous network refers to the introduction of other communication methods within the coverage of macro base stations to strengthen the coverage of specific areas in a targeted manner to form a network structure with multi-layer coverage. It has flexible network construction and low maintenance costs, so it is popular received widespread attention. [0003] The introduction of small cells into the macrocel...

However, due to the mobility of users, the use of a single threshold value control results in frequent opening and closing, which increases signaling overhead and greatly reduces user experience.
