Therefore, when to trigger the user equipment to perform AP discovery, and how to determine whether the user equipment is a subscriber, are not involved in the prior art, and therefore, the user equipment without permission to access the AP is interfered to cause a call drop.
In the embodiment of the invention, the triggering condition for carrying out the access point cell measurement is configured and issued for the user equipment, and the user equipment executes the corresponding access point cell measurement after receiving the triggering condition to carry out the access point discovery. After the target access point is found, the user equipment reports the identification information of the target access point and the identification information of the user equipment, so that the base station can acquire the identification information of the target access point and the identification information of the user equipment.

And when the user is determined to be a non-signed user, performing interference coordination on the user equipment, so as to reduce the interference of the target access point on the non-signed user.
In order to make the aforementioned objects, features and advantages of the present invention comprehensible, embodiments accompanied with figures are described in detail below.
An embodiment of the present invention provides an access point interference coordination method, which is described in detail below with reference to fig. 1 through specific steps.
Step S101, configuring a user equipment and sending a trigger condition for carrying out access point cell measurement to the user equipment.
In a specific implementation, the base station may configure a trigger condition for performing access point cell measurement for the user equipment, and issue the configured trigger condition to the user equipment. The user equipment can trigger the access point cell measurement after receiving the trigger condition, and can also trigger the access point cell measurement after receiving the indication information issued by the base station.
In the embodiment of the present invention, the access point cell may also be referred to as a small cell (small cell) or a Non-public network cell (NPN cell). The base station in the embodiment of the present invention may be a macro cell base station gNB or an access point cell base station.
In particular implementations, the base station configured trigger condition may include an interference measurement threshold.
In an embodiment of the present invention, after receiving the trigger condition, the ue detects the signal quality of the current serving cell. And if the signal quality of the current service cell is detected to be lower than the preset interference measurement threshold, the user equipment triggers the access point cell to measure by itself.
In another embodiment of the present invention, the user equipment detects the signal quality of the current serving cell after receiving the trigger condition. If the signal quality of the current service cell is lower than the preset interference measurement threshold, the user equipment reports the measurement result to the base station or reports an indication meeting the measurement condition of the access point cell. And after receiving the measurement result or the indication, the base station acquires that the signal quality of the current service cell of the user equipment is poor, and then sends a trigger indication to the user equipment. And after receiving the triggering indication, the user equipment discovers or measures the access point cell.
In a specific implementation, the interference measurement threshold may be a signal to interference and noise ratio (SINR) threshold, a Reference Signal Received Quality (RSRQ) threshold, or another threshold capable of characterizing signal quality of a current serving cell due to interference from a neighboring access point cell.
In a specific implementation, the trigger condition configured by the base station may include beam identification information.
In the embodiment of the present invention, after receiving the trigger condition, the ue detects the identification information of the beam of the current serving cell. And if the identification information of the beam of the current service cell is the same as the beam identification information contained in the triggering condition, triggering the measurement of the access point cell. The beam identification information may be a beam index, or an SSB index, or a CSI-RS index at which the user is receiving data.
For example, the identification information indicating the beam in the trigger condition is 2, that is, beam 2(beam 2). After receiving the trigger condition, the user equipment triggers the measurement of the access point cell when detecting that the beam of the current serving cell is beam 2.
In a specific implementation, the trigger condition configured by the base station may also include both the interference measurement threshold and the beam identification information.
In the embodiment of the present invention, after receiving the trigger condition, the ue detects the identification information of the beam of the current serving cell. And if the identification information of the beam of the current service cell is the same as the beam identification information contained in the trigger condition, measuring the signal quality of the current service cell. If the signal quality of the current service cell is detected to be lower than the preset interference measurement threshold, the measurement of the access point cell is triggered, or the measurement result or the indication is reported to the base station.
For example, there are 4 beams in the current serving cell of the user equipment. The trigger conditions configured by the base station comprise: beam 2, interference measurement threshold 1; beam 3, interference measurement threshold 2. The interference measurement threshold 1 and the interference measurement threshold 2 may be equal or different. After receiving the triggering condition, if the currently used beam is beam 2, the user equipment measures the SINR of the current serving cell, and if the SINR is smaller than a preset interference measurement threshold, triggers the access point cell to measure.
And step S102, receiving the reported information of the user equipment.
In a specific implementation, after triggering the access point cell measurement, the user equipment may search for an access point signal, acquire identification information of a target access point, and send the identification information of the target access point as reported information to the base station.
In the embodiment of the present invention, the reporting information of the ue may also carry identification information of the ue. After receiving the reported information of the user equipment, the base station can acquire the identification information of the target access point and the identification information of the user equipment.
In the embodiment of the present invention, the base station may also store the identification information of the user equipment in advance. If the user equipment does not report the identification information of the user equipment, the base station can use the stored identification information of the user equipment.
In the embodiment of the present invention, the identification information of the target access point may be a Global identity (CGI) of a Cell corresponding to the target access point, or may also be an access point base station identification, and the identification information of the target access point may further include other information capable of identifying the target access point, such as an addressable address and an IP address of the target access point. The access point identification information can be obtained by reading access point base station broadcast by user equipment.
The reported information may also include beam information of the target access point, where the beam information of the target access point may be an identifier of a beam interfering the user equipment or SSB identifier information sent by the access point base station and received by the user equipment. The reported information may also include a measurement result corresponding to the target access point cell.
In the embodiment of the present invention, the identification information of the ue may be an International Mobile Subscriber Identity (IMSI) of the ue, may also be subscription information reserved when the ue subscribes, and may also be other information capable of identifying the ue, such as a Mobile phone number.
Step S103, determining a target access point according to the identification information of the target access point, and sending the identification information of the user equipment to the target access point.
In a specific implementation, the base station may determine the target access point searched by the user equipment according to the received reported information. The base station may be addressed to the target access point based on the identification information of the target access point. The base station may send identification information of the user equipment to the target access point. After receiving the identification information of the user equipment, the target access point can judge whether the user equipment is a signed user or not, and obtain an authentication result. The base station can be addressed to the target access point base station through the core network or directly through the access point identification.
In the embodiment of the invention, the non-subscriber and the subscriber are relative concepts. In the embodiment of the present invention, for the target AP, the user equipment capable of accessing the target AP may be referred to as a subscriber for short, that is, the subscriber has the right to access the target AP. Accordingly, a macro network user device without the access authority of the target AP is called a non-subscriber.
In practical application, the target access point may store, in advance, identification information corresponding to the subscriber. The target access point, after receiving the identification information of the user equipment, may determine whether the identification information of the user equipment has already been stored. If the identification information of the user equipment is not pre-stored, the target access point judges that the user equipment is a non-signed user; otherwise, if the identification information of the user equipment is stored in advance, the target access point judges that the user equipment is a signed user.
Step S104, receiving the authentication result fed back by the target access point.
In a specific implementation, after obtaining the authentication result, the target access point may report the authentication result to the base station. The base station can know whether the user equipment is a signed user or a non-signed user according to the received authentication result.
Step S105, when the user equipment is determined to be a non-subscriber user, performing interference coordination on the user equipment.
In a specific implementation, if the base station determines that the user equipment is a non-subscriber user, the base station may perform interference coordination on the user equipment. And carrying out interference coordination on the user equipment, wherein the purpose is to reduce the interference of a target access point on the user equipment (an unauthorized user).
In the embodiment of the invention, the base station carries out interference coordination on the user equipment, and can carry out pilot frequency switching for configuring the user equipment, namely, the frequency where the user equipment currently resides is switched to other frequencies, thereby effectively avoiding the same frequency interference of the target access point to the user equipment.
In the embodiment of the present invention, if the report information sent by the user equipment further includes beam information of the target access point, when performing interference coordination on the user equipment, the base station may further coordinate the target access point to reduce the power of a beam corresponding to the beam information, that is, reduce the power of a beam used by the target access point, so as to reduce interference on the user equipment.
In a specific implementation, if the ue is a subscriber, the base station may prepare for a subsequent possible handover of the ue.
In the embodiment of the present invention, the target access point may send the cell measurement configuration information corresponding to the target access point to the base station. The base station may send the received cell measurement configuration information to the user equipment. The user equipment can perform cell measurement corresponding to the target access point according to the received cell measurement configuration information.
In the embodiment of the present invention, the measurement configuration information may include reference signal configuration information, measurement period, length, and other information (SMTC), and the reference configuration information may include synchronization signal block, CSI-RS, and other information. The content included in the measurement configuration information may refer to the prior art, and is not described in detail in the embodiments of the present invention.
In a specific implementation, the measurement configuration information may be configured in the same message as the authentication result. When receiving the message, the ue can acquire that the ue is a subscriber and corresponding measurement configuration information for performing cell measurement.
It can be seen that, in the embodiment of the present invention, a trigger condition for performing access point cell measurement is configured and issued for a user equipment, and the user equipment performs corresponding access point cell measurement after receiving the trigger condition, so as to perform access point discovery. After the target access point is found, the user equipment reports the identification information of the target access point and the identification information of the user equipment, so that the base station can acquire the identification information of the target access point and the identification information of the user equipment. The base station sends the identification information of the user equipment to the target access point, so that the target access point can acquire the identification information of the user equipment, and further can judge whether the user equipment is a signed user. And when the user is determined to be a non-signed user, performing interference coordination on the user equipment, so as to reduce the interference of the target access point on the non-signed user.
Referring to fig. 2, another access point interference coordination method in the embodiment of the present invention is shown, and is described in detail below through specific steps.
Step S201, receiving a trigger condition for access point cell measurement issued by a base station.
In a specific implementation, the base station may configure a trigger condition for performing access point cell measurement for the user equipment, and issue the configured trigger condition to the user equipment. The user equipment can trigger the access point cell measurement after receiving the trigger condition, and can also trigger the access point cell measurement after receiving the indication information issued by the base station.
In the embodiment of the present invention, an access point cell may also be referred to as a small cell (small cell) or a Non-public network cell (NPN cell). The base station in the embodiment of the present invention may be a macro cell base station gNB or an access point cell base station.
In particular implementations, the base station configured trigger condition may include an interference measurement threshold.
In an embodiment of the present invention, after receiving the trigger condition, the ue detects the signal quality of the current serving cell. And if the signal quality of the current service cell is detected to be lower than the preset interference measurement threshold, the user equipment triggers the access point cell to measure by itself.
In another embodiment of the present invention, the user equipment detects the signal quality of the current serving cell after receiving the trigger condition. If the signal quality of the current service cell is lower than the preset interference measurement threshold, the user equipment reports the measurement result to the base station or reports an indication meeting the measurement condition of the access point cell. And after receiving the measurement result or the indication, the base station acquires that the signal quality of the current service cell of the user equipment is poor, and then sends a trigger indication to the user equipment. And after receiving the triggering indication, the user equipment carries out access point cell discovery or measurement.
In a specific implementation, the interference measurement threshold may be a signal to interference and noise ratio (SINR) threshold, a Reference Signal Received Quality (RSRQ) threshold, or another threshold capable of characterizing signal quality of a current serving cell due to interference from a neighboring access point cell.
In a specific implementation, the trigger condition configured by the base station may include beam identification information.
In the embodiment of the present invention, after receiving the trigger condition, the ue detects the identification information of the beam of the current serving cell. And if the identification information of the beam of the current service cell is the same as the beam identification information contained in the triggering condition, triggering the measurement of the access point cell. The beam identification information may be a beam index, or an SSB index, or a CSI-RS index at which the user is receiving data.
For example, the identification information indicating the beam in the trigger condition is 2, that is, beam 2(beam 2). After receiving the trigger condition, the user equipment triggers the access point cell measurement when detecting that the beam of the current serving cell is beam 2.
In a specific implementation, the trigger condition configured by the base station may also include both the interference measurement threshold and the beam identification information.
In the embodiment of the present invention, after receiving the trigger condition, the ue detects the identification information of the beam of the current serving cell. And if the identification information of the beam of the current service cell is the same as the beam identification information contained in the trigger condition, measuring the signal quality of the current service cell. And if the signal quality of the current service cell is detected to be lower than the preset interference measurement threshold, triggering the measurement of the access point cell, or reporting the measurement result or the indication to the base station.
For example, there are 4 beams in the current serving cell of the user equipment. The trigger conditions configured by the base station comprise: beam 2, interference measurement threshold 1; beam 3, interference measurement threshold 2. The interference measurement threshold 1 and the interference measurement threshold 2 may be equal or different. After receiving the triggering condition, if the currently used beam is beam 2, the user equipment measures the SINR of the current serving cell, and if the SINR is smaller than a preset interference measurement threshold, triggers the access point cell to measure.
Step S202, sending report information to the base station, wherein the report information comprises identification information of a target access point.
In a specific implementation, after triggering the access point cell measurement, the user equipment may search for an access point signal, obtain identification information of a target access point, and send the identification information of the target access point as report information to the base station.
In the embodiment of the present invention, the reporting information of the ue may also carry identification information of the ue. After receiving the reported information of the user equipment, the base station can acquire the identification information of the target access point and the identification information of the user equipment.
In the embodiment of the present invention, the base station may also store the identification information of the user equipment in advance. If the user equipment does not report the identification information of the user equipment, the base station can use the stored identification information of the user equipment.
In the embodiment of the present invention, the identification information of the target access point may be a Global Cell identity (CGI) of a Cell corresponding to the target access point, or may also be an access point base station identification, and the identification information of the target access point may also include other information capable of identifying the target access point, such as an addressable address and an IP address of the target access point. The access point identification information can be obtained by reading access point base station broadcast by user equipment.
The reported information may also include beam information of the target access point, where the beam information of the target access point may be an identifier of a beam interfering the user equipment or SSB identifier information sent by the access point base station and received by the user equipment. The reported information may also include a measurement result corresponding to the target access point cell.
In the embodiment of the present invention, the identification information of the ue may be an International Mobile Subscriber Identity (IMSI) of the ue, may also be subscription information reserved when the ue subscribes, and may also be other information capable of identifying the ue, such as a Mobile phone number.
Step S203, receiving the control signaling sent by the base station, and performing interference coordination operation corresponding to the control signaling.
In a specific implementation, the base station may determine the target access point searched by the user equipment according to the received reported information. The base station may be addressed to the target access point based on the identification information of the target access point. The base station may send identification information of the user equipment to the target access point. After receiving the identification information of the user equipment, the target access point can judge whether the user equipment is a signed user or not, and obtain an authentication result. The base station can be addressed to the target access point base station through the core network or directly through the access point identification.
In the embodiment of the invention, the non-subscriber and the subscriber are relative concepts. In the embodiment of the present invention, for the target AP, the user equipment capable of accessing the target AP may be referred to as a subscriber for short, that is, the subscriber has the right to access the target AP. Accordingly, a macro network user device without the access authority of the target AP is called a non-subscriber.
In practical application, the target access point may store, in advance, identification information corresponding to the subscriber. The target access point, after receiving the identification information of the user equipment, may determine whether the identification information of the user equipment has already been stored. If the identification information of the user equipment is not pre-stored, the target access point judges that the user equipment is a non-signed user; otherwise, if the identification information of the user equipment is stored in advance, the target access point judges that the user equipment is a signed user.
In a specific implementation, after obtaining the authentication result, the target access point may report the authentication result to the base station. The base station can know whether the user equipment is a signed user or a non-signed user according to the received authentication result.
In a specific implementation, if the base station determines that the user equipment is a non-subscriber user, the base station may perform interference coordination on the user equipment. The base station can issue a control signaling to the user equipment, and the user equipment can execute corresponding interference coordination operation after receiving the control signaling. In a specific application, interference coordination is performed on user equipment, and the purpose is to reduce interference of a target access point on the user equipment (an unauthorized user).
In the embodiment of the invention, the base station carries out interference coordination on the user equipment, can carry out pilot frequency switching for configuring the user equipment, and sends a switching instruction to the user equipment. After receiving the switching instruction, the user equipment switches the currently resident frequency to other frequencies, thereby effectively avoiding the same frequency interference of the target access point to the user equipment.
In the embodiment of the present invention, if the report information sent by the user equipment further includes the beam information of the target access point, when performing interference coordination on the user equipment, the base station may further coordinate the target access point to reduce the power of the beam corresponding to the beam information, that is, reduce the power of the beam used by the target access point, so as to reduce the interference on the user equipment.
In a specific implementation, if the ue is a subscriber, the base station may prepare for a subsequent possible handover of the ue.
In the embodiment of the present invention, the target access point may send the cell measurement configuration information corresponding to the target access point to the base station. The base station may issue the received cell measurement configuration information to the user equipment. The user equipment can perform cell measurement corresponding to the target access point according to the received cell measurement configuration information.
