Description
Technical Field
The present invention relates to the field of communications technologies, and in particular, to a method and an apparatus for determining an indoor user.
Background
With the continuous rise of the traffic density in the building, most of the traffic occurs indoors, so that the indoor traffic proportion is gradually increased. In order to provide better service for indoor users, operators need to first master the proportion of indoor all user traffic to indoor and outdoor all user total traffic, or master the proportion of indoor all user traffic to indoor and outdoor all user total traffic, and then plan the indoor distribution system more reasonably according to the obtained traffic or traffic proportion.
in the implementation process of the above planning method, it is necessary to distinguish the indoor users from the outdoor users. Currently, a base station located indoors, that is, an indoor sub-base station, can distinguish an indoor user from an outdoor user according to whether a measurement report reported by a terminal carries GPS (Global Positioning System) information. The specific distinguishing mode is that when the measurement report reported by the terminal carries the GSP information, the terminal is considered as an outdoor user, otherwise, the user is considered as an indoor user.
however, considering that the existing network deployment is complex, and it is likely that an outdoor user cannot successfully count the GPS information due to signal interference or building occlusion, and the like, the indoor base station may incorrectly determine the terminal as an indoor user because the measurement report reported by the outdoor terminal does not carry the GPS information, thereby reducing the accuracy of the obtained traffic volume or the traffic volume ratio, and affecting the planning process of the indoor distribution system.
Disclosure of Invention
The invention provides a method and a device for determining an indoor user, which can solve the problem that the planning process of an indoor distribution system is influenced because the accuracy of the obtained telephone traffic or the proportion of the service volume is reduced because an outdoor user does not count GPS information.
In order to achieve the purpose, the invention adopts the following technical scheme:
in a first aspect, the present invention provides a method for determining an indoor user, the method comprising:
a base station acquires a reference signal sent by a terminal and determines the signal intensity of the base station, wherein the reference signal carries the transmitting power of the terminal;
the base station determines the signal intensity of the terminal according to the transmitting power of the terminal, the signal intensity of the base station and the transmitting power of the base station;
And when the signal intensity of the terminal is greater than the average signal intensity of the terminal in the indoor edge area, the base station determines that the terminal is an indoor user.
In a second aspect, the present invention provides an apparatus for determining an indoor user, the apparatus comprising:
the system comprises an acquisition module, a transmission module and a power management module, wherein the acquisition module is used for acquiring a reference signal sent by a terminal and determining the signal strength of a base station, and the reference signal carries the transmission power of the terminal;
a calculating module, configured to determine the signal strength of the terminal according to the transmission power of the terminal, the signal strength of the base station, and the transmission power of the base station;
and the comparison module is used for determining that the terminal is an indoor user when the signal intensity of the terminal is greater than the average signal intensity of the terminal in the indoor edge area.
compared with the prior art that whether the terminal reports the GPS information or not is counted to determine whether the terminal belongs to the indoor user or not, the method and the device for determining the indoor user provided by the invention compare the current signal intensity of the terminal with the average signal intensity of the terminal in the indoor edge area, and if the signal intensity of the terminal is greater than the average signal intensity, the terminal is determined as the indoor user. Considering that an edge region located indoors can be regarded as a region where the signal intensity is the smallest in the entire indoor region, in the present invention, the average signal intensity of the terminal belonging to the region can be used as a reference value for distinguishing indoor and outdoor users. Therefore, the base station can determine whether the terminal is an indoor user only by normally sending the reference signal by the terminal, so that whether the terminal is the indoor user can be determined only by receiving the reference signal sent by the terminal under the condition of not counting the GPS signal. That is, for a terminal that does not report a GPS signal, the base station can also determine whether the terminal is an indoor user, and therefore, the problem that the planning process of an indoor distribution system is affected due to the fact that the accuracy of the obtained telephone traffic or the ratio of the telephone traffic is reduced because an outdoor user does not count GPS information can be solved.

Detailed Description
The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.
an embodiment of the present invention provides a method for determining an indoor user, and as shown in fig. 1, the method may be applied to a base station. In the present invention, the base station may be a indoor base station, hereinafter referred to as a base station. The method comprises the following steps:
101. The base station acquires the reference signal sent by the terminal and determines the signal strength of the base station.
The reference signal carries the transmission power of the terminal.
In the invention, the terminal can transmit the sounding reference signal, and the transmission power of the terminal is carried in the reference signal. After receiving the reference signal transmitted by the terminal, the base station may obtain the transmission power of the terminal from the reference signal, and may also detect its own signal strength, that is, the received power of the reference signal.
102. and the base station determines the signal intensity of the terminal according to the transmitting power of the terminal, the signal intensity of the base station and the transmitting power of the base station.
103. and when the signal intensity of the terminal is greater than the average signal intensity of the terminal in the indoor edge area, the base station determines that the terminal is an indoor user.
Considering that all indoor terminals are in the coverage area of the base station, and can perform data interaction with the base station, and the terminal closer to the base station can receive the signal from the base station with higher signal strength, in the present invention, the terminal can be determined to be an indoor user or an outdoor user according to the magnitude relationship between the signal strength of the signal received by the terminal and the average signal strength of the terminal located in the indoor edge.
The present invention compares the current signal intensity of the terminal with the average signal intensity of the terminal located in the indoor edge area, and if the signal intensity of the terminal is greater than the average signal intensity, the terminal is determined as the indoor user. Considering that an edge region located indoors can be regarded as a region where the signal intensity is the smallest in the entire indoor region, in the present invention, the average signal intensity of the terminal belonging to the region can be used as a reference value for distinguishing indoor and outdoor users. Therefore, the base station can determine whether the terminal is an indoor user only by normally sending the reference signal by the terminal, so that whether the terminal is the indoor user can be determined only by receiving the reference signal sent by the terminal under the condition of not counting the GPS signal. That is, for a terminal that does not report a GPS signal, the base station can also determine whether the terminal is an indoor user, and therefore, the problem that the planning process of an indoor distribution system is affected due to the fact that the accuracy of the obtained telephone traffic or the ratio of the telephone traffic is reduced because an outdoor user does not count GPS information can be solved.
in order to enable the base station to accurately grasp the signal strength of the terminal without using additional resources to obtain the signal strength of the terminal, in an implementation manner of the embodiment of the present invention, the base station may determine the signal strength of the terminal according to the equivalent relationship between the uplink path loss and the downlink path loss and according to the obtainable transmission power of the terminal and the signal strength of the base station. Therefore, on the basis of the implementation shown in fig. 1, the implementation shown in fig. 2 can also be realized. In step 102, the base station determines the signal strength of the terminal according to the transmission power of the terminal, the signal strength of the base station, and the transmission power of the base station, which may be specifically implemented as step 1021 and step 1022:
1021. And the base station determines the difference value between the transmitting power of the terminal and the signal strength of the base station as the uplink loss.
1022. And the base station determines the signal strength of the terminal according to the uplink path loss and the transmitting power of the base station.
in the present invention, the uplink loss PL _ UP of the terminal can be expressed according to the formula PL _ UP ═ RP _ N-TP _ U. Wherein, RP _ N is the self-received power detected by the base station after receiving the reference signal, i.e. the signal strength of the base station; TP _ U is the transmit power at which the terminal transmits the reference signal.
in the invention, the parameter can be determined to be greater than the average signal intensity of the terminal at the indoor edge by comparing the parameter with the average signal intensity of the terminal at the indoor edge, and the terminal can be determined as an indoor user.
In one implementation of the embodiments of the present invention, the uplink path loss is the same as the downlink path loss,
therefore, on the basis of the implementation shown in fig. 2, the implementation shown in fig. 3 can also be realized. Wherein, in step 1022, the base station determines the signal strength of the terminal according to the uplink loss and the transmission power of the base station, which may be specifically implemented as step 10221:
10221. and the base station determines the difference value between the transmitting power of the base station and the downlink path loss as the signal strength of the terminal.
Considering that the uplink path loss and the downlink path loss have substantially the same value, in the present invention, in order to reduce extra resource waste, the base station may determine the signal strength of the signal transmitted by the base station and capable of being received by the terminal according to the already obtained parameters, and therefore, the signal strength RP _ U of the terminal may be determined according to the calculated uplink path loss PL _ UP. The specific calculation formula for determining the signal strength of the terminal may be: RP _ U is TP _ N-PL _ D. Wherein TP _ N is the transmission power of the base station, and PL _ D is the downlink path loss, which may be equal in value to the uplink path loss obtained through the above calculation.
In one implementation manner of the embodiment of the present invention, in order to provide a relatively accurate reference value, before determining an indoor user, the base station may determine the average signal strength of the terminal in the indoor edge area by obtaining an indoor drive test result. Therefore, based on the implementation shown in fig. 2 or fig. 3, taking fig. 2 as an example, the implementation shown in fig. 4 can also be implemented. Before the base station determines that the terminal is an indoor user when the signal strength of the terminal is greater than the average signal strength of the terminal located in the indoor edge area in step 103, step 104 may also be performed:
104. and the base station acquires the average signal intensity of the terminal obtained by the drive test of the terminal in the indoor edge area.
In the invention, the signal strength of the terminal at each position of the indoor edge area can be obtained through drive test. And then, averaging the acquired signal intensities of all the terminals to determine the average as a reference value for judging whether the terminal is an indoor user. Therefore, the problem that the planning process of an indoor distribution system is influenced due to the fact that the accuracy of the obtained telephone traffic or the proportion of the service volume is reduced because the outdoor user does not count the GPS information can be solved. Then, a request may be sent to the network side to request to acquire the traffic and/or traffic statistics of all indoor users, and then, the indoor substations, that is, all the traffic and/or traffic statistics of all indoor users within the coverage of the base station, are counted.
An embodiment of the present invention provides an apparatus 20 for determining an indoor user, as shown in fig. 5, where the apparatus 20 may be configured to perform the method flows shown in fig. 1 to fig. 4, and the apparatus is applied to a base station, such as a indoor base station.

And the calculating module 22 is configured to determine the signal strength of the terminal according to the transmission power of the terminal, the signal strength of the base station, and the transmission power of the base station.
And the comparison module 23 is configured to determine that the terminal is an indoor user when the signal strength of the terminal is greater than the average signal strength of the terminals located in the indoor edge area.

further, the apparatus 20 may further include:
the traffic statistic module 24 is configured to send a request to a network side to request to acquire traffic and/or traffic statistics of all indoor users, and then count out all traffic and/or traffic statistics of all indoor users in the coverage area of the base station.
The present invention compares the current signal intensity of the terminal with the average signal intensity of the terminal located in the indoor edge area, and if the signal intensity of the terminal is greater than the average signal intensity, the terminal is determined as the indoor user. Considering that an edge region located indoors can be regarded as a region where the signal intensity is the smallest in the entire indoor region, in the present invention, the average signal intensity of the terminal belonging to the region can be used as a reference value for distinguishing indoor and outdoor users. Therefore, the base station can determine whether the terminal is an indoor user only by normally sending the reference signal by the terminal, so that whether the terminal is the indoor user can be determined only by receiving the reference signal sent by the terminal under the condition of not counting the GPS signal. That is, for a terminal that does not report a GPS signal, the base station can also determine whether the terminal is an indoor user, and therefore, the problem that the planning process of an indoor distribution system is affected due to the fact that the accuracy of the obtained telephone traffic or the ratio of the telephone traffic is reduced because an outdoor user does not count GPS information can be solved.
