The information of the user location is reported to the DL device by a Core Access and Mobility Management Function (AMF) device in a subscription-triggered manner. When the AMF device receives a terminal source request sent by a terminal or a user location change notification sent by a wireless access Network side, the AMF device sends information after the user location information changes to the DL device through the terminal source request or the user location change notification, and the DL device sends the received terminal source request or the user location change notification to a Network Function (NF) device, a Network Exposure Function (NEF) device, and the like, which have subscribed to the user location.

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.

Example 1:

an embodiment of the present invention provides a user location notification control method, as shown in fig. 1, including the following steps:

s11: a Location Management Function (LMF) device collects first state information of an AMF device, the first state information including at least one of the following first parameter groups: the first load value set and the number of users within the management scope are both comprised of at least one first parameter.

The user number group in the AMF device management range includes at least one first parameter, which may be the user number of the whole area or the user number of the partial area. When the number of users in the AMF device management range is too large, the location change of too many users will impact the performance and stability of the network system, so the number of users in the AMF device management range can be used as the control basis.

And the AMF equipment updates the number of users in the self management range in real time according to the users in the self management range, and stores the updated number of users. Specifically, the user located in the management range of the AMF device reports the information of the user to the AMF device, so that the AMF device knows which users are in the management range.

Similarly, in the management range of the AMF device, the number of users whose positions change is in direct proportion to the first load value, and the change of the excessive user positions may cause the first load value of the AMF device to be excessive, so the first load value may be used as the first parameter in the first load value group, and thus may be used as the basis for control. The first set of load values includes at least one first parameter. For example, the first parameter included in the first load value group may be a first signaling link load, where the first signaling link load is a load of each signaling link in a management range of the AMF device, or a load of a plurality of preset signaling links. The AMF equipment acquires the load condition of each signaling link in real time, and calculates a first signaling link load value of each signaling link according to the load condition. The first signalling link load value for each signalling link that the AMF device will calculate may be stored locally. The calculation of the load value of each signaling link is not described in detail herein for the prior art.

S12: and judging whether at least one first parameter larger than a corresponding first set threshold exists in the first state information.

The specific first set threshold includes a threshold corresponding to each first parameter in the first state information, where the threshold corresponding to each first parameter may be the same or different. Preferably, the administrator can set the threshold corresponding to each first parameter according to the performance requirement of the system. The LMF device collects at least one first parameter group of the AMF device, specifically at least one of the first load value group and the user number group in the management range, wherein each first parameter group comprises at least one first parameter.

When the LMF equipment acquires that the first parameter group of the AMF equipment is the first load value group, judging whether a first parameter larger than a corresponding first set threshold exists in the first load value group; when the LMF device acquires that the first parameter group of the AMF device is the user number group in the management range, judging whether a first parameter larger than a corresponding first set threshold exists in the user number group in the management range; when the LMF device simultaneously acquires that the first parameter group of the AMF device is the first load value group and the user number group within the management range, it may be determined whether the first load value group and the user number group within the management range have a first parameter greater than a corresponding first set threshold.

S13: and if so, sending a notification to the AMF device to indicate that the AMF device stops sending the user position notification.

The user location notification control method provided by the embodiment of the invention is applied to LMF equipment, and the first state information of the AMF equipment is acquired, wherein the first state information comprises at least one of the following first parameter groups: and if at least one first parameter which is larger than a corresponding first set threshold exists in the first state information, sending a notification to the AMF equipment to instruct the AMF equipment to stop sending the user position notification. Otherwise, it is stated that there are not too many user locations simultaneously changed within the AMF device management range, and there is no impact on the stability of the network, so the LMF device sends a notification to the AMF device to instruct the AMF device to send a user location notification. Or not processing, and processing the AMF equipment according to the existing mode.

In order to further ensure that the first status information can accurately reflect whether there is a change in the location of the excessive users, in an embodiment of the present invention, the first load value group includes at least one of the following first parameters: a link load value, an average load value and a peak load value;

The link load value, the average load value and the peak load value are all in direct proportion to the number of users having changed location, so the first parameter in the first load value group includes: at least one of a link load value, an average load value, and a peak load value. The first load value group can be a first parameter group, and the link load value, the average load value, and the peak load value can all be first parameters in the first load value group, the first load value group including at least one first parameter. And when the LMF judges that at least one first parameter larger than the corresponding first set threshold exists in the first parameters included in the first load value group, sending a notification to the AMF equipment to indicate the AMF equipment to stop sending the user position notification. For example, when the first load value group includes three first parameters, namely, a link load value, an average load value and a peak load value, when at least one of the link load value, the average load value and the peak load value is greater than a corresponding first set threshold, a notification is sent to the AMF device instructing the AMF device to stop sending the user location notification.

Similarly, the first parameter in the group of the number of users in the management scope includes: at least one of a total number, a number of powered-on users, and a number of talking users. The group of the number of users in the management range may be used as a first parameter group, and the total number, the number of the power-on users, and the number of the call users may be used as first parameters in the group of the number of users in the management range, where the group of the number of users in the management range includes at least one first parameter. And when the LMF equipment judges that at least one first parameter which is larger than a corresponding first set threshold exists in the first parameters included in the user number group in the management range, sending a notification to the AMF equipment to indicate the AMF equipment to stop sending the user position notification. For example, the group of the number of users in the management scope includes: and when at least one of the total number, the number of the power-on users and the number of the call users is greater than a corresponding first set threshold, sending a notification to the AMF equipment to indicate that the AMF equipment stops sending the user position notification.

Example 2:

in order to further ensure network stability and improve system performance, on the basis of the foregoing embodiments, in an embodiment of the present invention, if there is no first parameter greater than a corresponding first set threshold in the first state information, the method further includes:

When the first parameters are not greater than the corresponding first set threshold, which indicates that the number of users currently having location change is not too large, it may be determined whether to send a notification to the AMF device to instruct the AMF device to stop sending user location notifications according to the network state of the AMF device.

It should be noted that the first status information comprises at least one first parameter group, and each first parameter group comprises at least one first parameter; wherein the first load value group and the group of the number of users within the management range can be both used as the first parameter group. And when all the first parameters in the first parameter group included in the first state information are judged to be not larger than the corresponding first set threshold, acquiring a network state index group of the AMF equipment.

Here, the collected network state index set of the AMF device may reflect a network state of the current AMF device, and the network state index set includes at least one second parameter reflecting the network state of the AMF device. If at least one second parameter greater than a corresponding second set threshold exists in the network state index group, which indicates that the network state is not good at this time, a notification is sent to the AMF device to indicate that the AMF device stops sending the user location notification.

The specific AMF device obtains the network state in the current measurement period once in each measurement period, where the network state index group reflecting the network state may be at least one of the number of bytes sent by the ethernet port, the number of bytes received by the ethernet port, the number of times that all the routes in the signaling route set are unavailable, the number of times that the signaling route is unavailable, the length of time that all the links in the link set are interrupted, the length of time that the signaling link set is unavailable, the number of times that the link is in a congestion state is accumulated, the length of time that the link is not in a service state is accumulated, the number of times that an outgoing call is made by a predetermined gateway, and the number of times that the call fails due to unavailable relay.

Specifically, the AMF device may store the obtained result of the network state index set locally. It should be noted that how the AMF device obtains the network status indicator set is not described in detail herein for the prior art. Example 3:

When the first parameters are not greater than the corresponding first set threshold, which indicates that the number of users currently having location change is not too large, at this time, it may be determined whether to send a notification to the AMF device to instruct the AMF device to stop sending user location notifications according to the network element state of the AMF device.

It should be noted that, the condition for determining when to collect the network element status indicator group of the AMF device in the embodiment of the present invention is the same as that in embodiment 2, and details are not described herein again.

Here, the collected network element state index set of the AMF device may reflect a network element state of a network element in the current AMF device, and the network element state index set includes at least one third parameter reflecting the network element state of the AMF device. And if at least one third parameter larger than a corresponding third set threshold exists in the network element state index group, which indicates that the network element state is not good at this time, sending a notification to the AMF equipment to indicate that the AMF equipment stops sending the user position notification.

The specific AMF device acquires the network element state in the current measurement period once in each measurement period, where the network element state index group reflecting the network element state may be at least one of the number of outbound gateway call attempts and the number of network cause call failures in one measurement period, for example.

Specifically, the AMF device stores the obtained result of the network element status indicator set locally. It should be noted that how the AMF device obtains the set of network element status indicators is not described in detail herein for the prior art.

Example 4

It should be noted that information of any one of the DL device, the NF device, and the NEF device may be collected, or information of any plurality of devices may be collected; the collected information may include any one of the second signaling link load value and the central processing unit usage rate, or both the second signaling link load value and the central processing unit usage rate.

For example, a second signaling link load value and a central processor utilization rate of each of the DL device, the NF device and the NEF device are collected; if any one of the DL equipment, the NF equipment and the NEF equipment is larger than a corresponding fourth set threshold value, any one of the load value of a second signaling link or the utilization rate of the central processing unit is larger than the corresponding fourth set threshold value; and the LMF equipment sends a notice to the AMF equipment to indicate the AMF equipment to stop sending the user position notice. The fourth setting threshold corresponding to the second status information of each of the DL device, the NF device, and the NEF device may be set according to respective performance, that is, the fourth setting threshold corresponding to each device may be the same or different.

The utilization rate of the central processing unit is used as an important parameter of the equipment and is monitored by the equipment in real time. And the load condition of the signaling link is used as an important parameter for reflecting the current device network state, and the load value is also monitored in real time and can be stored locally, wherein the calculation of the load value of each signaling link is not repeated for the prior art.
