Description
Technical Field
The present invention relates to the field of communications technologies, and in particular, to a method, an apparatus, a system, and a computer storage medium for controlling a base station to sleep and wake up.
Background
In a Long Term Evolution (LTE) system, a terminal device supports an idle state and a connected state; in a New Radio or New Radio (NR) system, a terminal device supports an idle state, an inactive state, and a connection state, and states other than the connection state, such as the idle state and the inactive state, may be referred to as the inactive state. According to the mobile network management principle, when the terminal is in a non-connection state, the network cannot accurately position the base station where the terminal resides, and only can position the terminal in a position area.
In order to meet the demand of faster speed of general consumers, and the demand of ultra-large scale link terminals and ultra-low delay in the industrial field, mobile communication networks are developing towards larger bandwidth and larger scale antenna arrays. With the consequent higher power consumption, the 4G network energy consumption cost accounts for 25% of the whole network operation cost according to the statistics of a certain operator. The 5G system adopts a larger bandwidth and a massive MIMO technology, so that the energy consumption of the BBU and the AAU is greatly improved, and the power consumption of the 5G base station is more than 3 times that of the 4G base station.
Therefore, how to reduce the energy consumption of the base station is a key issue related to the operation cost of the operator. At present, the conventional scheme for saving energy of a base station is that operation and maintenance personnel count busy and idle time periods of each station based on traffic, and then a network manager sets sleep time of each base station to enable the base station to enter a sleep state when the traffic is low. The scheme has the advantages of large workload, inaccurate sleep time and no consideration of the terminal in a non-connection state when the base station is in sleep. When the base station is not clear of the residence situation of the non-connected terminal, forced closing of the base station will cause some terminals to enter a coverage loss state, resulting in degraded user experience.
The key process is also when the base station wakes up after sleeping, and especially when the sleeping base station appears in a coverage blind area, if the base station cannot be awakened in time, the terminal can be disconnected. The current wake-up scheme is timed wake-up, wake-up when the detected traffic is high. However, the solutions all have obvious defects, and no consideration is given to the non-connected terminals, so that even if a large number of non-connected terminals enter the coverage area of the dormant base station, the base station cannot be woken up.

To further illustrate the specific working process of the present invention, the following is described:
as shown in fig. 5, the base station 1 performs wide coverage, has a large influence range of sleep, and allows to enter a sleep state at regular time;
the base station 2 carries out indoor blind complementing coverage and always allows the base station to enter a dormant state;
the base station 3 performs a hot-patch to the base station, and always allows the base station to enter a sleep state.
The base station 4 performs wide-coverage blind-patch coverage, and a coverage blind area exists around the base station, so that the base station is not allowed to enter a dormant state all the time.
After the base station 1 enters the dormant state, when the terminal moves to the edge of the base station adjacent to the base station 1 and approaches the base station 1, the base station where the terminal is located triggers the problem of terminal mobility because the base station 1 is in the dormant state, so as to wake up the base station 1. After the base station 1 wakes up, the terminal reselects or switches to the base station 1. The user does not perceive the whole process, and the user experience is not influenced.
After the base station 2 enters the dormant state, when the terminal moves indoors in the base station 1 and approaches the base station 2, the base station 1 may trigger the terminal mobility problem due to the dormant state of the base station 2, thereby waking up the base station 2. After the base station 1 wakes up, the terminal moves to the base station 2 through reselection or handover. The user does not perceive the whole process, and the user experience is not influenced.
When the terminal moves from the indoor covered by the base station 2 to the outdoor covered by the base station 1, if the base station 1 is in a dormant state, the base station 2 can trigger the problem of terminal mobility to wake up the base station 1; and if the base station 1 is in a normal working state, the terminal moves to the base station 1 for outdoor coverage through reselection or the change of the purple calyx. The base station 2 detects that there is no terminal and enters a sleep state. The user does not perceive the whole process, and the user experience is not influenced.
When the base station 1 is busy, it detects that the traffic is higher than a certain threshold, and triggers to wake up the base station 3.
The base station 4 does not always perform the sleep state, and the coverage blind area is not enlarged. When the terminal moves from the shadow area to the base station 4, the network service can be obtained. Similarly, when the terminal moves from the base station 4 to the base station 1, if the base station 1 is in a dormant state, the base station 4 may trigger a mobility problem, wake up the base station 1, and ensure continuous network service of the terminal. It may also be configured to allow the base station 4 to enter the dormant state when the base stations 5, 6, 7 have no terminals, and not allow the base station 4 to enter the dormant state when the base stations 5, 6, 7 have terminals, so as to save further energy.
It should be noted that no matter what kind of base station is used, no essential influence is generated on the implementation of the embodiment of the present invention. No matter the base station is a macro base station, a micro base station, a distributed base station, an indoor base station and an outdoor base station, no matter what type of base station, no essential influence is generated on the implementation of the embodiment of the invention.
