Description

Base station power control method and device

technical field

The invention relates to the field of communication technology, in particular to a base station power control method and equipment in the field of communication systems.

Background technique

In a communication system, power control is required for both uplink and downlink. When the level and quality of the received signal at the receiving end are very good, the transmission power of the opposite end can be appropriately reduced to keep the communication quality at a certain level, which can reduce the interference to other calls in the surrounding area.

In the prior art, the communication system judges whether to adjust the transmit power of the base station according to the current communication quality, and how to adjust the transmit power of the base station if the transmit power of the base station needs to be adjusted. Taking the Global System for Mobile Communication (GSM for short) communication system as an example, the transmission power control of the base station by the GSM communication system depends on the downlink measurement information regularly sent by the user equipment (UE) to the base station. Report. The base station sends the received measurement report sent by the UE to the corresponding base station controller (BaseStation Controller, BSC for short), and the BSC judges the transmit power of the base station according to the content of the measurement report. Therefore, in the GSM system, the time required for the BSC to control the power of the base station is at least one measurement report sending period.

When the call is just established, the measurement report is sent in the Slow Associated Control Channel (Slow Associated Control Channel, referred to as SACCH) control channel, after the call is established, the measurement report is sent in the traffic channel (Traffic Channel, referred to as TCH). In these two cases, the sending period of the measurement report is 470ms and 480ms respectively. Since the BSC adjusts the transmit power of the base station for power control based on the measurement report information, it takes at least 470ms or 480ms to update the decision information once. When the network environment changes rapidly, the transmit power control of the base station may not be timely enough.

Detailed ways

The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only some, not all, embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the protection scope of the present invention.

In order to make the above objects, features and advantages of the embodiments of the present invention more comprehensible, the embodiments of the present invention will be further described in detail below in conjunction with the accompanying drawings and specific implementation methods.

The power control method of the base station in the embodiment of the present invention can be applied to a communication system using Adaptive Multi-Rate (Adaptive Multi-Rate, referred to as AMR) speech coding technology, which can be a 2G, 3G or 4G communication system. Taking Global System For Mobile Communications (GSM for short) as an example, 3G is Wideband Code Division Multiple Access (WCDMA for short), or Time Division-Synchronous Code Division Multiple Access (Time Division-Synchronous Code Division Multiple Access). Access, referred to as: TD-SCDMA), or Code Division Multiple Access CDMA2000 as an example, and 4G as an example of a Long Term Evolution system (LongTerm Evolution, referred to as: LTE). In the above communication system, the power control method using the embodiment of the present invention is similar. For the convenience of description, the embodiment of the present invention takes the GSM communication system as an example for specific description.

Fig. 1 is a schematic flow chart of a base station transmission power control method according to an embodiment of the present invention. As shown in Fig. 1, the base station transmission power control method includes the following steps:

Step 110, receiving a coding mode request (codemode request, CMR for short) sent by the user equipment UE;

The coding mode request CMR sent by the user equipment UE is received, the CMR includes the coding mode, and the base station is requested to send data to the UE in the coding mode in the CMR.

In the GSM system, when using the AMR speech coding technology, the UE periodically sends a CMR to the base station, requesting the base station to send a signal to the UE in the coding mode requested in the CMR. The UE sends a CMR to the base station every 40 ms by stealing voice frames, and the CMR carries the coding mode for sending downlink signals requested by the UE to the base station. That is, the base station receives the CMR sent by the UE every 40ms.

It can be understood that in the GSM communication system, changes in the quality of the air interface between the UE and the base station will lead to unstable communication quality. When the quality of the air interface changes, the proportion of effective signals in the transmission signals that the UE can accept is different, so the encoding mode for the UE to request the base station to send signals is also correspondingly different.

When the quality of the air interface is good, the effective information in the signal transmitted between the UE and the base station is more, and the redundancy is less, corresponding to the coding mode with higher effective signal. When the quality of the air interface is poor, the transmission between the UE and the base station There is less effective information in the signal, and more redundancy is needed to detect bit errors, corresponding to a coding mode with a lower effective signal.

Therefore, when the quality of the air interface becomes better, the UE sends a CMR to the base station, requesting the base station to send downlink signals to the UE in a coding mode with a higher number. On the contrary, when the quality of the air interface deteriorates, the UE sends a CMR to the base station, requesting the base station to send downlink signals to the UE in a coding mode with a lower number. When the air interface quality remains unchanged, when the air interface quality is good, the UE sends a CMR with a higher effective signal ratio to the base station, and when the air interface quality is poor, the UE sends a CMR with a lower effective signal ratio to the BRS.

Step 120, obtaining the encoding mode in the CMR;

The CMR sent by the UE to the base station includes a coding mode, and the base station obtains the coding mode of the CMR from the received CMR signal. It can be realized that when the air interface quality is good, the effective signal ratio of the coding mode is high, and when the air interface quality is poor, the effective signal ratio of the coding mode is low. Different encoding modes in CMR can be distinguished by numbers or specific symbols or different names.

Step 130, adjusting the transmit power of the base station according to the encoding mode;

It can be known from the description in step 110 that the current air interface quality can be judged according to the coding mode. For example, the current air interface quality level can be judged from the coding mode required in the received CMR, and the change of the air interface quality can be judged from the change of the coding mode required in the CMR. The base station can comprehensively determine whether the transmit power of the base station needs to be adjusted based on the level of the air interface quality and the change of the air interface quality, and how to perform the adjustment when the transmit power of the base station needs to be adjusted.

When adjusting the transmit power of the base station according to the encoding mode, the signal quality and signal level transmitted between the UE and the base station can meet certain requirements, and stable and better communication quality can be obtained. Therefore, when the communication quality is poor, it is necessary to increase the transmit power of the base station in time. When the communication quality is good, the transmit power of the base station can be appropriately reduced. It can be understood that adjusting the transmit power of the base station here refers to adjusting the transmit power of the base station for the channel where the UE is located. Usually, the adjustment of the transmit power of the base station is based on the principle of fast rise and slow fall, so that the signal can be maintained at a better level.

In this embodiment, the CMR periodically sent by the UE is received, the coding mode requested in the CMR is obtained, and the transmit power of the base station is adjusted according to the number value and the change of the number value. Since the CMR transmission period is 40ms, the base station can make a judgment every 40ms, and can adjust its own transmission power in time according to the quality of the air interface, so as to achieve the purpose of fast power control and make the power control of the base station adapt to changes in the network environment in a timely manner.

Fig. 2 is a schematic flow chart of another base station transmission power control method according to an embodiment of the present invention. As shown in Fig. 2 , a base station transmission power control method according to another embodiment of the present invention includes the following steps:

Step 210, receiving the coding mode request CMR sent by the user equipment UE;

Wherein, for a specific receiving manner, reference may be made to step 110 in the previous embodiment.

Step 220, acquire the encoding mode in the CMR;

Wherein, for a specific receiving manner, reference may be made to step 120 in the previous embodiment.

In the step, when the coding modes in the CMR distinguish different coding modes by coding, the ratios of effective signals transmitted by coding modes with different numbers are different. Assume that the CMR set contains 4 coding modes numbered 1-4, MODE1, MODE2, MODE3, MODE4, and the proportion of effective signals of coding modes with numbers from small to large is getting higher and higher. When the UE sends the CMR to the base station to request that the coding mode sent by the base station is MODE1, it means that the number of the coding mode obtained is 1, and so on for other coding modes. It can be understood that, since the UE periodically sends the CMR to the base station, the base station correspondingly periodically receives the CMR sent by the UE, and the base station obtains the serial number of the coding mode in the successively received CMR requests.

Since different numbered coding modes mean different air interface quality, it can be understood that the adjusted transmit power is to achieve better and stable communication quality, which requires that the signal quality and signal level transmitted between the UE and Require. When the communication quality is poor, it is necessary to increase the transmission power in time. When the communication quality is very good, the transmit power can be reduced appropriately.

The base station can determine the current air interface quality level from the coding mode number required in the received CMR, and at the same time, the base station can judge the change of the air interface quality from the change of the coding mode number required in the CMR. The base station can comprehensively determine whether the transmit power of the base station needs to be adjusted based on the level of the air interface quality and the change of the air interface quality, and how to perform the adjustment when the transmit power of the base station needs to be adjusted.

Step 230, judging whether the number of the encoding mode remains unchanged;

In this step, the transmit power of the base station needs to be adjusted according to the number of the coding mode. If the result of the judgment is that the number of the coding mode remains unchanged, perform step 240 , and if the result of the judgment is the number of the coding mode, perform step 250 . In steps 240 and 250, according to whether the encoding mode number changes, it is divided into two situations and applied.

Step 240, when the serial numbers of multiple coding modes remain unchanged, adjust the transmit power of the base station according to the serial numbers of the coding modes;

When the changes of multiple consecutive coding modes remain unchanged, it means that the quality of the air interface is basically stable, and the value of the coding mode can be used to judge whether the quality of the air interface is stable at a poor state or a good state, and thus can be determined Whether it is necessary to adjust the transmit power of the base station.

Step 250, when the number of the coding mode changes, adjust the transmit power of the base station according to the change of the coding mode number;

It can be seen from the above that the change of the encoding mode number means the change of the air interface quality, so the change of the air interface quality can be determined according to the change of the encoding mode number, and when the air interface quality changes, adjust the transmit power of the base station to make the signal meet a certain quality .

It can be understood that the specific number of consecutive multiples in this step may be preset. When two coding modes are used for judgment, one transmission CMR cycle is required for a base station transmission power adjustment decision; when three coding modes are used for judgment, two transmission CMR cycles are required for one base station transmission power adjustment judgment cycle, other situations, and so on.

In this embodiment, when the serial numbers of multiple coding modes remain unchanged, in step 240, the transmit power of the base station may be adjusted according to one or a combination of the following methods:

When the encoding mode number is less than the first preset threshold, increase the transmit power of the base station; compare the encoding mode number with the first preset threshold, assuming that in MODE1, MODE2, MODE3, MODE4, when the encoding requested by the CMR When the mode is MODE1 and MODE2, it means that the quality of the air interface is poor and needs to be adjusted, so the first preset threshold of the number can be set to 2. When the coding mode remains unchanged, if the number of the coding mode is less than or equal to 2, the transmit power of the base station needs to be increased. It can be understood that the first preset threshold can be set as required.

If the coding mode number is greater than the second preset threshold, the transmit power of the base station is reduced. Assuming that the second preset threshold is 4, when the encoding mode is MODE4, it means that the air interface quality is very good, and the transmit power of the base station can be slowly reduced. Likewise, the second preset threshold can be set as required.

In addition, in this embodiment, when the number of the coding mode changes, step 250 can adjust the transmit power of the base station according to one or a combination of the following methods:

When the coding mode number decreases to the first preset threshold, the transmit power of the base station is increased. When the coding mode number decreases, it can be judged that the quality of the air interface is degraded. In this case, there are two possibilities. The first situation is that although the quality of the air interface is degraded, the signal quality can still be relatively good. Correspondingly, although the coding mode number decreases, it does not decrease to the first preset threshold, so there is no need to increase the transmit power of the base station. The second situation is that the quality of the air interface is reduced, and after the reduction, the number of the coding mode in the CMR requested by the UE is reduced to the first preset threshold, indicating that the quality of the air interface is not enough to provide better signal quality for the UE. Therefore, It is necessary to increase the transmit power of the base station. For example, when the first preset threshold of encoding is 2, if the encoding mode changes from MODE4 to MODE3, there is no need to increase the transmit power of the base station, and if the encoding mode changes from MODE3 to MODE1, or from MODE2 to MODE1, there is no need To increase the transmit power of the base station, it is necessary to increase the transmit power of the base station in time.

When the coding mode number increases to a second preset threshold, the transmit power of the base station is reduced. When the coding mode number increases, it can be judged that the quality of the air interface is improved. In this case, there are two possibilities. The first situation is that although the quality of the air interface is improved, better signal quality cannot be provided. Correspondingly, although the number of the coding mode increases, it does not increase to the second preset threshold, so the transmit power of the base station cannot be reduced. The second situation is that the quality of the air interface is improved, and after the improvement, the number of the coding mode in the CMR requested by the UE increases to the second preset threshold, indicating that the quality of the air interface has been improved to a very high quality. Therefore, it is necessary to increase the transmit power of the base station . In order to ensure better communication quality, the second preset threshold may be greater than the first preset threshold. For example, when the first preset threshold of the number is 2, the second preset threshold of the number can be set as 4.

In addition, in this embodiment, in addition to the base station can independently adjust the transmit power of the base station according to the encoding mode in the above-mentioned embodiment, it can also be combined with the prior art to adjust the transmit power of the base station according to the instruction of the base station controller, wherein the base station control The instruction of the device is formed according to the UE periodic measurement report. The encoding mode and the measurement report are jointly used as factors for adjusting the transmit power of the base station.

In this embodiment, when the encoding mode and the measurement report are used to adjust the transmit power of the base station, the range of steps for adjusting the transmit power of the base station using the encoding mode can be limited, so that the step of adjusting the transmit power of the base station according to the encoding mode is smaller than that of the base station The step of transmitting power of the base station is adjusted according to the instruction of the base station controller. For example, the step range for adjusting the transmit power of the base station according to the encoding mode may be set to be between 2db-10db. In this way, on the basis of adjusting the transmit power of the base station according to the UE measurement report in the prior art, the transmit power of the base station can be adjusted in a relatively small range by using the coding mode as a fine-tuning, so that the transmit power of the base station can change smoothly.

It can be understood that, according to different systems applied in this embodiment, the base station can be BTS, NodeB and e-NodeB, and the base station controller can be BSC, radio network controller (RadioNetwork Controller, RNC for short) and e-NodeB.

In this embodiment, the coding mode number is used to judge whether the quality of the air interface is good or bad, as well as its change, so as to adjust the transmit power of the base station. Since the number of the coding mode is specified in the agreement, the transmit power of the base station can be adjusted according to the clearly determined content in the existing agreement. In this embodiment, setting the power adjustment step in a smaller range can make the power adjustment more stable. Combining the adjustment of the power through the encoding mode with the adjustment of the transmission power of the base station in the prior art, the adjustment of the transmission power of the base station can be performed in a timely and stable manner.

The receiving module 301 is configured to receive a coding mode request CMR sent by the user equipment UE, and the CMR requests the base station to send data to the UE in the coding mode in the CMR.

In the GSM system, when using the AMR speech coding technology, the UE periodically sends a CMR, requesting the base station to send a signal to the UE in the coding mode requested in the CMR. The UE sends a CMR every 40 ms in the form of stealing voice frames, and the CMR carries the coding mode for sending downlink signals requested by the UE to the base station. The receiving module receives the CMR sent by the UE every 40ms.

The obtaining module 302 is configured to obtain the encoding mode in the CMR received by the receiving module.

The obtaining module 302 obtains the coding mode from the CMR signaling received by the receiving module 301 . It can be realized that when the air interface quality is good, the effective signal ratio of the coding mode is high, and when the air interface quality is poor, the effective signal ratio of the coding mode is low. Different encoding modes in CMR can be distinguished by numbers or specific symbols or different names.

The first adjustment module 303 is configured to adjust the transmit power of the base station according to the coding mode acquired by the acquisition module.

Since the current air interface quality can be judged according to the encoding mode acquired by the acquisition module, the first adjustment module can determine whether the transmission power of the base station needs to be adjusted according to the encoding mode and the change of the encoding mode, and when the transmission power of the base station needs to be adjusted, How to make adjustments.

It can be understood that the device in this embodiment may be a base station, or may be a module with independent functions that can be connected to the base station.

In this embodiment, the receiving module receives the CMR periodically sent by the UE, the acquiring module acquires the coding mode requested in the CMR, and the first adjusting module adjusts the transmit power of the base station according to the value of the number and the change of the number value. Since the transmission cycle of CMR is 40ms, the device in this embodiment can make a decision every 40ms, and can adjust its own transmission power in time according to the quality of the air interface, so as to achieve the purpose of fast power control and make the power control of the base station adapt to the network in time. environmental changes

FIG. 4 is a schematic structural diagram of a base station transmission power control device according to another embodiment of the present invention. As shown in FIG. , the first adjustment module 403 includes a first adjustment unit 4031, or/and, a second adjustment unit 4032:

The first adjusting unit 4031 is configured to adjust the transmit power of the base station according to the numbers of the coding modes when the numbers of the consecutive coding modes remain unchanged.

When the changes of multiple consecutive coding modes remain unchanged, it means that the quality of the air interface is basically stable, and the value of the coding mode can be used to judge whether the quality of the air interface is stable at a poor state or a good state, and thus can be determined Whether it is necessary to adjust the transmit power of the base station.

The second adjusting unit 4032 is configured to adjust the transmit power of the base station according to the change of the coding mode number when the coding mode number changes.

The change of the coding mode number means the change of the air interface quality. Therefore, the change of the air interface quality can be determined according to the change of the coding mode number. When the air interface quality changes, the transmit power of the base station is adjusted to make the signal meet a certain quality.

In addition, in this embodiment, the first adjusting unit 4031 may further include: a first increasing subunit 40311, or/and, a first reducing subunit 40312:

The first increasing subunit 40311 is configured to increase the transmit power of the base station when the coding mode number is smaller than the first preset threshold.

Assuming that in MODE1, MODE2, MODE3, MODE4, when the encoding mode of the CMR request is MODE1 and MODE2, it means that the quality of the air interface is poor and needs to be adjusted, then the first preset threshold of the number can be set to 2. When the coding mode remains unchanged, if the number of the coding mode is less than or equal to 2, the transmit power of the base station needs to be increased. It can be understood that the first preset threshold can be set as required.

The first reducing subunit 40312 is configured to reduce the transmit power of the base station when the coding mode number is greater than the second preset threshold.

Assuming that the second preset threshold is 4, when the encoding mode is MODE4, it means that the air interface quality is very good, and the transmit power of the base station can be slowly reduced. Likewise, the second preset threshold can be set as required.

In this embodiment, the second adjusting unit 4032 may further include: a second increasing subunit 40321, or/and, a second reducing subunit 40322:

The second increasing subunit 40321 is configured to increase the transmit power of the base station when the coding mode number decreases to the first preset threshold.

If the number of the coding mode in the CMR requested by the UE decreases to the first preset threshold after the quality of the air interface decreases, it means that the quality of the air interface is not enough to provide better signal quality for the UE, and the second improvement subunit increases the transmit power of the base station .

The second reducing subunit 40322 is configured to reduce the transmit power of the base station when the coding mode number increases to a second preset threshold.

The air interface quality is improved, and after the improvement, the number of the coding mode in the CMR requested by the UE increases to the second preset threshold, indicating that the air interface quality has been improved to a very high quality, therefore, the transmit power of the base station needs to be reduced. In order to ensure better communication quality, the second preset threshold may be greater than the first preset threshold.

In this embodiment, a second adjustment module may also be included, which adjusts the transmission power of the base station according to an existing method for adjusting the transmission power of the base station. For example, the second adjustment module may adjust the transmit power of the base station according to the instruction of the base station controller, and the instruction of the base station controller is formed according to the periodic measurement report of the UE. That is, the first adjustment module can be used alone to adjust the transmission power of the base station, or can be combined with the second adjustment module to adjust the transmission power of the base station. It can be understood that the second adjustment module is used to adjust the transmit power of the base station according to the UE periodic measurement report. The adjustment time is relatively long and the step is relatively large. The step size may be smaller than the step size at which the second adjustment module adjusts the transmit power of the base station according to the instruction of the base station controller.

In this embodiment, the first adjustment unit and the second adjustment unit respectively judge the quality of the air interface and the change of the air interface quality through the coding mode number and the change of the coding mode number, so as to adjust the transmit power of the base station. Since the number of the coding mode is specified in the agreement, the transmit power of the base station can be adjusted according to the clearly determined content in the existing agreement. The first reducing subunit, the first increasing subunit, the second reducing subunit, and the second improving subunit can judge whether it is necessary to adjust the base station transmit power through the preset threshold, so that the base station transmit power can be increased in time when the air interface quality is poor. Power, and slowly reduce the transmit power of the base station when the quality of the air interface is good, so as to maintain stable communication quality while adjusting the transmit power of the base station smoothly.
