Specific embodiment
Fig. 1 is a kind of communication system architecture figure, and this application can be applied to RRU-BBU scenes as shown in Figure 1 for this, but are not limited thereto.
As shown in Figure 1, the scene framework may include: baseband processing unit (Building Baseband Unit, abbreviation BBU), RRU hub (RHUB) and multiple RRU.
Wherein, RRU can be the component part of distributed base station.RRU can be micro- RRU (pico-RRU, abbreviation pRRU) in above-mentioned framework.
Multiple RRU can be disposed according to specific scene at various locations, in order to provide service to the terminal of different location.Such as general medium-and-large-sized Indoor environment area reaches 20,000 square metres~50,000 square metres, or even has and reach 100,000 square metres, to complete in-door covering scheme a set of in this way, pRRU required for disposing is up to tens to hundreds of.
Multiple RRU are connect by RHUB with BBU, and BBU can control the switch state of each RRU, that is, control the power-on and power-off of each RRU.Optionally, BBU controls the power-on and power-off of each RRU by RHUB.
In the application, aiming at the problem that how to reduce energy consumption in a fairly large number of situation of RRU, put forward a kind of by method electric under idle RRU, the method different from only closing RRU partial function at present can preferably reduce energy consumption.
Fig. 2 is a kind of control method flow diagram of Remote Radio Unit provided by the present application, and the executing subject of this method can be BBU.As shown in Fig. 2, this method comprises:
S201, monitor in default monitoring range whether accessed terminal under each power-up state RRU.
All RRU under some indoor scene can be managed by a BBU, after BBU starting monitoring, the RRU of all power-up states in oneself range of management can be detected, optionally, it is monitored in range of management under all logic districts under each power-up state RRU whether accessed terminal by monitoring object of logic district.When general just starting monitoring, all RRU are all in power-up state in range of management.
Specifically monitor whether accessed under each RRU have terminal, if illustrating that this RRU does not need to provide service for terminal at present without any terminal, in free time.
S202, the interior power-up state RRU in preset duration without access terminal of default monitoring range is determined.
S203, will be electric under the RRU in the power-up state RRU in above-mentioned preset duration without access terminal in addition to presetting normally opened RRU.
Wherein, certain power-up state RRU are always maintained at no terminal in preset duration and need to service, that is, are constantly in the free time, then can directly lower electricity.It is electric under RRU in all power-up state RRU that no terminal can be accessed in addition to presetting normally opened RRU.
In order to flexibly control the switch state of RRU in monitoring range, need to set some normally opened RRU, these normally opened RRU are kept powered on state accessing without any terminal, after electricity under other RRU, if there is terminal accesses normally opened RRU, BBU controls other RRU again and powers on.Generally, one or more normally opened RRU can be set previously according to the deployed position of RRU, the mark for presetting normally opened RRU is stored in BBU, preset the inlet that normally opened RRU is generally set in monitoring range, such as the key positions such as doorway, corridor, these positions are usually that user enters the position that may first pass through after monitoring range, to guarantee that BBU timely learning has terminal access, and then power on other necessity RRU for user service while providing service for terminal, customer service is not influenced while saving energy.
In the present embodiment, it monitors in default monitoring range and whether has accessed terminal under each power-up state RRU, determine the power-up state RRU in default monitoring range in preset duration without access terminal, it will be electric under the RRU in the power-up state RRU of above-mentioned no access terminal in addition to presetting normally opened RRU, realizing can be directly lower electric with energy conservation by the RRU of temporary standby according to monitoring situation, retain the not lower electricity of some normally opened RRU again simultaneously, in order to flexibly according to terminal access again by user needed for RRU power on, guarantee user service while saving energy.
Optionally, it monitors in default monitoring range and whether has accessed terminal under each power-up state RRU, can be, monitor in default monitoring range whether accessed terminal under each power-up state RRU in default monitoring time section.
Default monitoring time section is predetermined the low traffic period, and the low traffic period can indicate that the terminal quantity for needing to service is little or no.Specifically, for most of indoor scene, the user that may need to provide service within some periods is more, these periods are not the low traffic periods, and without being monitored, all RRU are powered on；User volume within other periods in possible scene is extremely low, i.e., in the low traffic period, so that it may monitoring is opened, so as to which electricity realization under the RRU of some free time is energy saving.
Herein with some common scenes for example:
(1) transport hub area, such as: airport, railway station, bus station, these scenes are generally white Its user volume is huge, and all RRU are powered on, and can set the place opening time to preset monitoring time section, user volume can be reduced, even without opening can be by electricity under most of RRU with energy conservation after monitoring in this period in place shut-in time to morning in the evening.
(2) public places such as megastore, supermarket, and the work and study place such as office building, school, generally there is fixed user's flowing law in these places, as there is fixed opening time in market, closes a business the time, office building has work hours and quitting time, but close a business the time/quitting time may also have employee or other necessary personnel to enter activity, default monitoring time section can be so set according to user's flowing law, in the monitoring function that closes a business the time/open in the quitting time, i.e., the execution above method is by electricity under most of free time RRU with energy conservation.
Further, it monitors and whether has accessed terminal under each power-up state RRU, it can be by judging whether there is new terminal access to determine whether that access has terminal under each power-up state RRU, and/or by judging whether each power-up state RRU with terminal has interaction data stream to determine whether terminal.
Open monitoring when BBU can first know whether accessed terminal under RRU, if under some RRU originally access have terminal, can see whether with terminal interaction data, if not provided, may this terminal exit access；If natively accessed without terminal under some RRU, new terminal access is monitored whether, if not provided, explanation is idle always.
It determines the power-up state RRU in default monitoring range in preset duration without access terminal, may is that
It determines in preset duration not with terminal interaction data and the power-up state RRU of not new terminal access.
It should be noted that can not include multiple RRU under one physical area with each RRU for a cell, include multiple physical areas under a logic district under the scene that the application is applicable in.Specifically, logic district can refer to a local resource, possess the whole world unified cell ID and cell association attributes, such as: frequency point, bandwidth, Physical Cell Identifier, transmission power parameter.The coverage area of logic district can be single side antenna footprint, be also possible to multi-panel antenna footprint.Physical area can refer to a practical coverage area, be radio frequency combining between each antenna point in this coverage area.
If there are all RRU of logic district, all lower electricity, stopping monitor in the logic district whether accessed terminal under RRU in default monitoring range.
When specific implementation, it monitors in default monitoring range and whether has accessed terminal under each power-up state RRU, it can be the terminal accessed under each physical area in each logic district of real-time monitoring and Business Stream, if in preset duration, without access terminal also without Business Stream under some physical area, then directly by this It is electric under all RRU under a physical area in addition to presetting normally opened RRU.If the normally opened RRU of Non-precondition in this physical area, the physical area can be no longer monitored after all lower electricity of all RRU under this physical area.Similarly, if all lower electricity of all RRU under some logic district, can also no longer monitor the logic district, until it is subsequent there is terminal to access again after, trigger that the logic district is next or after multiple RRU power on, then re-start monitoring.
In addition, after electricity energy conservation under the RRU of part, can also be needed again to be powered on these by the RRU of lower electricity according to user in default monitoring time section.Such as after some office building opens monitoring at night, most of RRU has user to return to office building overtime work suddenly by lower electricity, then again can be powered on part RRU according to the demand of the user.
Optionally, it monitors that normally opened RRU is preset in new terminal access, which is obtained according to default RRU topology；The RRU that lower electricity is at least one adjacent R RU is powered on.
Some terminal accesses after some presets normally opened RRU, in order to preferably be the user service, at least one adjacent R RU for presetting normally opened RRU is powered on, the terminal may move, these RRU can continue to be monitored after powering on, in turn, monitoring power on after other RRU have new terminal access after, also the adjacent R RU for powering on the RRU of terminal access according to RRU topology is preset, and so on, the RRU that user needs is powered on.Since in default monitoring time section, idle RRU also can realize the power-on and power-off for adjusting RRU according to the access of terminal in the case where user is less, in time by lower electricity in order to also not delay while energy conservation for user service.
Above-mentioned default RRU topology is used to identify the neighbouring relations in default monitoring range between RRU.
It should be noted that the RRU that user needs is powered on according to monitoring situation be also possible to independent embodiment.
Specifically, in monitoring process, there is terminal to access RRU, at least one adjacent R RU of the RRU is obtained according to default topology；The RRU that power-down state is in this at least one adjacent R RU is all powered on.Monitor that the RRU under some power-up state has new terminal to access, so just the adjacent all RRU of the RRU are powered on, when occurring mobile in order to terminal, service is provided in time for terminal, required RRU can be powered on when user needs according to flexible monitoring by realizing, service is provided for user, also ensures that the service of user is unaffected while saving energy.
Other embodiments are all similar in previous embodiment, and details are not described herein.
Optionally, presetting RRU topology can be in advance by manually according to the position coordinates of RRU actual deployment It is established, and established default RRU topology is stored in BBU.
Default RRU topology can also be established according to signal quality parameter by BBU oneself.
Fig. 3 is the control method flow diagram of another Remote Radio Unit provided by the present application, as shown in figure 3, it may include following process that BBU, which establishes default RRU topology:
S301, the terminal signaling metrical information for obtaining each RRU forwarding in default monitoring range.
The signal quality information may include: the mark of terminal and the signal quality parameter by terminal measurement.
Optionally, BBU can be in default statistical time section, measuring signal mass parameter is indicated to the terminal of access by RRU, the signal measurement that the terminal accessed under each RRU will be sent according to the RRU received obtains signal quality parameter, and signal quality parameter is sent to RRU, signal quality parameter is transmitted to BBU again by RRU, specifically, terminal can be to send data packet to RRU, signal quality parameter is carried in data packet, RRU does not parse the data packet, and BBU determines the data packet that RRU is sent after receiving, then decoding obtains the channel quality parameter of the inside.
S302, according to terminal signaling metrical information, determine at least one RRU that each RRU is adjacent in default monitoring range.
Specifically, the terminal signaling metrical information that can be forwarded according to each RRU successively determines the neighbouring relations between every two RRU.The signal quality parameter difference that the same terminal that general two neighboring RRU is got reports is in a certain range.
