Technical Field

Background

In the core network, a plurality of core network devices can form a core network device pool group, so that the switching time delay among the core network devices is reduced, and the utilization rate of network resources is improved. For example, an access and mobility management function (AMF) device in a fifth generation mobile communication technology (5G) core network and a mobility management node (MME) device in a fourth generation mobile communication technology (4G) core network may be integrated on a target core network device to reduce a handover delay of a terminal between a 4G network and a 5G network.

Currently, when a terminal switches between a 4G network and a 5G network, a suitable core network device is usually selected through a networking policy configured in advance by a core network device pool. In this case, if the networking policy pre-configured for the core network device pool group does not include the core network device integrated with the AMF device and the MME device, the switching delay of the terminal between the 4G network and the 5G network is increased, and the network resource utilization rate is reduced.

The following describes in detail a data processing method provided in an embodiment of the present application, with reference to the communication system shown in fig. 1 and the data processing apparatus shown in fig. 2 (or fig. 3).

Example one

Fig. 4 is a schematic flowchart of a data processing method according to an embodiment of the present application. As shown in fig. 4, a data processing method provided in the embodiment of the present application includes: S401-S402.

S401, the data processing device obtains service data when the terminal is switched from a first network system to a second network system.

The service data comprises a target core network equipment identifier selected when the terminal is switched from a first network standard to a second network standard, switching times under the target core network equipment, a switching success rate and a switching time delay.

Specifically, when using a service, the terminal needs to interact with the radio access network device and the core network device. In this case, the data processing apparatus may acquire signaling data between the terminal and the radio access network device and between the terminal and the core network device. Correspondingly, when the terminal is switched from the first network system to the second network system, the data processing device acquires service data when the terminal is switched from the first network system to the second network system.

Optionally, after acquiring the service data when the terminal is switched from the first network type to the second network type, the data processing device may perform a preprocessing operation on the service data. The preprocessing operation is mainly used for checking and filtering logic error data, abnormal data, repeated value data and the like in the service data.

Optionally, the service data further includes: a program type field or a globally unique temporary terminal identification. After the program type field or the globally unique temporary terminal identifier is obtained, the data processing device can also determine the first network type and the second network type according to the program type field or the globally unique temporary terminal identifier.

Illustratively, if the program type field in the service data is 61: and N2 HO In, the first network type can be determined to be a 4G network, and the second network type can be determined to be a 5G network. I.e. the terminal switches from the 4G network to the 5G network.

For example, if the globally unique temporary terminal identifier in the service data is not equal to the MME group identifier but is equal to the 5G globally unique temporary terminal identifier, it may be determined that the first network type is a 5G network and the second network type is a 4G network. I.e. the terminal switches from the 5G network to the 4G network.

S402, if the service data meet the preset conditions, the data processing device adds the target core network equipment identifier into the networking strategy.

The networking strategy is used for indicating the core network equipment selected to be accessed by the terminal.

Specifically, after acquiring the service data when the terminal is switched from the first network system to the second network system, the data processing device judges whether the service data meets the preset condition. And if the service data meet the preset conditions, the data processing device adds the target core network equipment identifier into the networking strategy.

Optionally, the preset condition is: the switching times of the terminal under the target core network device are larger than a first threshold, the switching success rate of the terminal under the target core network device is larger than a second threshold, and the switching time delay of the terminal under the target core network device is smaller than a third threshold.

That is, if the number of times of switching of the terminal under the target core network device is greater than the first threshold, the success rate of switching of the terminal under the target core network device is greater than the second threshold, and the switching delay of the terminal under the target core network device is less than the third threshold, it is determined that the service data meets the preset condition.

Further optionally, when the data processing apparatus determines the first threshold, the second threshold, and the third threshold, the data processing apparatus may first obtain the switching times, the switching success rate, and the switching delay of the terminal in each core network device when the terminal is switched from the first network system to the second network system, and determine the first threshold, the second threshold, and the third threshold according to the switching times, the switching success rate, and the switching delay of the terminal in each core network device.

Specifically, the data processing apparatus may sort the number of times of handover under each core network device in descending order, and determine the sorted a-th number of times of handover as the first threshold. Wherein a is a positive integer. In this case, the first threshold indicates that the number of times of handover of the terminal in the core network device is large. When the switching frequency of the terminal under the target core network equipment is greater than the first threshold value, the switching frequency of the terminal under the target core network equipment is more.

The data processing device may also sort the handover success rates of each core network device in descending order, and determine the b-th handover number after sorting as a second threshold. Wherein b is a positive integer. In this case, the second threshold indicates that the handover success rate of the terminal under the core network device is high. When the handover success rate of the terminal under the target core network device is greater than the second threshold, it indicates that the handover success rate of the terminal under the target core network device is higher.

The data processing device may also sort the handover delays under each core network device in an order from small to large, and determine the c-th handover number after sorting as a third threshold. Wherein c is a positive integer. In this case, the third threshold indicates that the handover delay of the terminal under the core network device is low. And when the switching delay of the terminal under the target core network equipment is smaller than a third threshold value, the switching delay of the terminal under the target core network equipment is lower.

In summary, when the number of times of switching of the terminal under the target core network device is greater than the first threshold, the success rate of switching of the terminal under the target core network device is greater than the second threshold, and the delay of switching of the terminal under the target core network device is smaller than the third threshold, it indicates that the number of times of switching of the terminal under the target core network device is greater, the success rate of switching of the terminal under the target core network device is higher, and the delay of switching of the terminal under the target core network device is lower. In this case, the target core network device satisfies the preset condition, and the data processing apparatus adds the target core network device identifier to the networking policy.

Optionally, when the data processing apparatus adds the target core network device identifier to the networking policy, it may also be determined whether the networking policy includes the target core network device identifier. And if the networking strategy comprises the target core network equipment identifier, the data processing device ensures that the target core network equipment identifier is reserved in the networking strategy. And if the networking strategy does not comprise the target core network equipment identifier, the data processing device adds the target core network equipment identifier to the networking strategy.

An embodiment of the present application provides a data processing method, including: firstly, service data when a terminal is switched from a first network system to a second network system is obtained. The service data comprises a target core network equipment identifier selected when the terminal is switched from a first network standard to a second network standard, switching times under the target core network equipment, a switching success rate and a switching time delay. If the service data meets the preset conditions, adding the target core network equipment identifier into the networking strategy; the networking strategy is used for indicating the core network equipment selected to be accessed by the terminal.

It can be seen that, when the terminal is switched from the first network system to the second network system, the data processing apparatus acquires the service data of the terminal, and adds the target core network device identifier to the networking policy when the service data meets the preset condition. The networking strategy is used for indicating the core network equipment selected to be accessed by the terminal, so that the data processing device can add the target core network equipment meeting the preset condition into the networking strategy, so that the target core network equipment meeting the preset condition can be selected when the terminal switches the network system, and the technical problems of high switching delay and low network resource utilization rate of the conventional terminal when the network system is switched are solved.

Example two

Taking the example of switching the terminal from the 4G network to the 5G network, fig. 5 shows a flowchart of another data processing method provided in this embodiment of the present application. As shown in fig. 5, a data processing method provided in the embodiment of the present application includes: S501-S503.

S501, the data processing device obtains the switching times, the switching success rate and the switching time delay of the terminal from the 4G network to the 5G network under each MME device.

When the terminal is switched from the 4G network to the 5G network, the data processing apparatus may acquire, from the service data of the terminal, the number of times of switching of the terminal from the 4G network to the 5G network under each MME device.

Specifically, the data processing apparatus may obtain a pointer type of the AMF device from the service data of the terminal, and identify the AMF device identifier by the pointer type of the AMF device. Correspondingly, the data processing device represents the MME equipment identifier through the 4G MME mapped by the temporary identifier of the 5G mobile user.

After obtaining the AMF device identifier and the MME device identifier, the data processing apparatus determines the number of times of switching of the MME device corresponding to each AMF device according to the correspondence between the AMF device and the MME device.

When the terminal is switched from the 4G network to the 5G network under each MME device, some AMF devices comprise N26 interfaces and some AMF devices do not comprise the N26 interfaces for different AMF devices.

When the AMF equipment comprises an N26 interface, the data processing device determines the switching success rate of the terminal from the 4G network to the 5G network under each MME equipment according to the ratio of the successful times of the terminal switching from the 4G network to the 5G network to the switching times of the terminal switching from the 4G network to the 5G network.

When the AMF equipment does not comprise the N26 interface, the data processing device determines the switching success rate of the terminal from the 4G network to the 5G network under each MME equipment according to the ratio of the number of times of successful reselection of the terminal from the 4G network to the 5G network to the number of times of request of the terminal from the 4G network to the 5G network.

For different AMF devices, the data processing device can filter the service data with the program state of 1 and count the average time delay of the service data.

Specifically, when the AMF device includes the N26 interface, the data processing apparatus determines the handover delay of the terminal from the 4G network to the 5G network under each MME device according to a ratio between a time of the terminal being handed over from the 4G network to the 5G network and a number of times of success of the terminal being handed over from the 4G network to the 5G network.

When the AMF equipment does not comprise the N26 interface, the data processing device determines the switching time delay of the terminal from the 4G network to the 5G network under each MME equipment according to the ratio of the time of switching the terminal from the 4G network to the 5G network to the request times of switching the terminal from the 4G network to the 5G network.

S502, the data processing device determines the target MME equipment according to the switching times, switching success rate and switching time delay of the terminal to be switched from the 4G network to the 5G network under each MME equipment.

Specifically, after acquiring the number of times of switching of the terminal from the 4G network to the 5G network under each MME device, the data processing apparatus sorts the number of times of switching under each MME device in descending order, and determines the first three sequenced MME devices as a first MME device group.

Correspondingly, after the switching success rate of the terminal switched from the 4G network to the 5G network under each MME device is obtained, the data processing device sorts the switching success rates under each MME device in descending order, and determines the first three sequenced MME devices as a second MME device group.

Correspondingly, after acquiring the switching delay of the terminal from the 4G network to the 5G network under each MME device, the data processing apparatus sorts the switching delays under each MME device in the descending order, and determines the first three sequenced MME devices as a third MME device group.

If the first MME device group, the second MME device group, and the third MME device group all include the same MME device, the data processing apparatus determines the same MME device as the target MME device.

S503, the data processing device adds the target MME device identification to the networking policy.

Optionally, when the data processing apparatus adds the target MME device identifier to the networking policy, it may further determine whether the networking policy includes the target MME device identifier. And if the networking strategy comprises the target MME equipment identifier, the data processing device ensures that the target MME equipment identifier is reserved in the networking strategy. And if the networking strategy does not comprise the target MME equipment identification, the data processing device adds the target MME equipment identification to the networking strategy.

EXAMPLE III

Taking the example of switching the terminal from the 5G network to the 4G network, fig. 6 shows a flowchart of another data processing method provided in this embodiment of the present application. As shown in fig. 6, a data processing method provided in the embodiment of the present application includes: S601-S603.

S601, the data processing device obtains the switching times, the switching success rate and the switching time delay of the terminal from the 5G network to the 4G network under each AMF device.

When the terminal is switched from the 5G network to the 4G network, the data processing apparatus may obtain, from the service data of the terminal, the number of times of switching of the terminal from the 5G network to the 4G network under each AMF device.

Specifically, the data processing apparatus may obtain an MME code of the MME device from service data of the terminal, and identify the MME device identifier by the MME code of the MME device. Correspondingly, the data processing device can also represent the AMF equipment identification through 3-4 bits of temporary mobile subscriber identification.

After acquiring the MME device identifier and the AMF device identifier, the data processing apparatus determines the number of times of switching of the AMF device corresponding to each MME device according to the correspondence between the MME device and the AMF device.

When the terminal is switched from the 5G network to the 4G network under each AMF device, for different MME devices, some MME devices include an N26 interface, and some MME devices do not include the N26 interface.

When the MME device comprises an N26 interface, the data processing device determines the switching success rate of the terminal from the 5G network to the 4G network under each AMF device according to the ratio of the successful times of the terminal switching from the 5G network to the 4G network to the switching times of the terminal switching from the 5G network to the 4G network.

When the MME device does not comprise the N26 interface, the data processing device determines the switching success rate of the terminal from the 5G network to the 4G network under each AMF device according to the ratio of the successful times of the terminal reselecting from the 5G network to the 4G network to the request times of the terminal switching from the 5G network to the 4G network.

For different MME devices, the data processing apparatus may filter the service data with the program state 1, and count the average delay.

Specifically, when the MME device includes an N26 interface, the data processing apparatus determines the handover delay of the terminal from the 5G network to the 4G network under each AMF device according to a ratio between a time when the terminal is handed over from the 5G network to the 4G network and a number of times of success for the terminal to be handed over from the 5G network to the 4G network.

When the MME device does not comprise the N26 interface, the data processing device determines the switching time delay of the terminal from the 5G network to the 4G network under each AMF device according to the ratio of the time of switching the terminal from the 5G network to the 4G network to the request times of switching the terminal from the 5G network to the 4G network.

S602, the data processing device determines the target AMF equipment according to the switching times, switching success rate and switching time delay of the terminal for switching from the 5G network to the 4G network under each AMF equipment.

Specifically, after acquiring the switching times of the terminal under each AMF device from the 5G network to the 4G network, the data processing apparatus sorts the switching times under each AMF device in descending order, and determines the first three sorted AMF devices as the first AMF device group.

Correspondingly, after acquiring the switching success rate of the terminal for switching from the 5G network to the 4G network under each AMF device, the data processing device sorts the switching success rates under each AMF device in descending order, and determines the first three sorted AMF devices as a second AMF device group.

Correspondingly, after the switching delay of the terminal from the 5G network to the 4G network under each AMF device is obtained, the data processing device sorts the switching delays under each AMF device in descending order, and determines the first three sorted AMF devices as a third AMF device group.
