For a clear description of the forwarding device selection method provided by an embodiment of the present invention, please refer to fig. 1 to fig. 3.

In an embodiment, the forwarding device is connected to the access device, the access device covers to form a tracking area, the user terminal 20 in the tracking area is connected to the forwarding device through the access device, the forwarding device includes a first forwarding device, a second forwarding device, and a third forwarding device, the movement level information supported by the third forwarding device is higher than the movement level information supported by the second forwarding device, and the movement level information supported by the second forwarding device is higher than the movement level information supported by the first forwarding device.

In one embodiment, the forwarding device may be a UPF as described above; the access device may be a base station, for example, a 5G base station (gNB), and forms a Tracking Area (TA) by signal coverage. Meanwhile, in the present embodiment, a specific form of the user terminal 20 is taken as an example (the description is omitted), and in an actual situation, the user terminal 20 is not limited to a mobile terminal, but may also include a fixed terminal, so as to meet a selection requirement of a forwarding device in a fixed-mobile convergence scenario. The specific form of the mobile terminal may include, but is not limited to, a mobile phone, a tablet computer, a personal digital assistant (abbreviated as PDA), a mobile Internet device (abbreviated as MID), a wearable device (such as a smart watch), and the like.

In an embodiment, the forwarding devices include a first forwarding device, a second forwarding device, and a third forwarding device, and the forwarding devices are distinguished in a first, second, and third manner, so as to indicate that there is a difference in the level of movement level information supported by each of the forwarding devices of different categories. Wherein the third forwarding device supports higher mobility level information than the second forwarding device supports, and the second forwarding device supports higher mobility level information than the first forwarding device supports. The specific representation of the level of the mobility level information that can be supported by the forwarding device may be the number of access devices connected to the forwarding device, or the size of a covered tracking area, or the number of user terminals that can be simultaneously supported, and the like, and is not limited specifically. In this embodiment, the number of access devices connected to a forwarding device is taken as an example of a determination criterion for distinguishing a first forwarding device, a second forwarding device, and a third forwarding device. Specifically, the first forwarding device may be connected to a first number of access devices; the second forwarding equipment is connected with a second number of access equipment, and the second number is greater than the first number; the third forwarding devices are connected to a third number of access devices, the third number being greater than the second number. And fig. 2 is a specific implementation scenario, where the first number is set to 1, the second number is set to 2, and the third number is set to 3, so that the forwarding device 1 in the figure belongs to the first forwarding device, the forwarding device 2 belongs to the second forwarding device, and the forwarding device 3 belongs to the third forwarding device, that is, the level of the movement level information supported by the forwarding device can be determined by the number of access devices to which the forwarding device is connected. Further, that is to say, the forwarding devices in the same hierarchy may include a plurality of forwarding devices, for example, there is a forwarding device 4 (not shown in the figure) connected to the access device 2, and since the number of connections is 1, the forwarding device 1 and the first forwarding device belong to the same class, and in the same way, the description of the situation of the second forwarding device or the third forwarding device may be omitted here. The above arrangement is only a simple arrangement for facilitating understanding of the scheme, and in practical situations, it is only necessary to satisfy that the movement level information supported by the third forwarding device is higher than that of the second forwarding device, and the second forwarding device is higher than that of the first forwarding device, where the influence of which factor is specifically relied on, or the number of the forwarding devices included in each forwarding device and other factors do not constitute a limitation to the technical scheme of the present application. Further, in the present embodiment, the forwarding devices are classified into three types, and the actual situation is not limited to this, and may be only two types, or may be more than three types. It can be understood that the present application focuses on distinguishing the first forwarding device, the second forwarding device, and the third forwarding device according to the level of the movement level information that can be supported by each forwarding device, rather than specifically distinguishing several types, and the number of the distinguished types does not limit the technical solution of the present application. Specifically, the method for selecting a forwarding device according to an embodiment of the present invention includes the following steps S110 to S120, and may refer to fig. 1.

Step S110: in response to receiving the session establishment request sent by the user terminal 20, the mobility level information of the user terminal 20 is obtained, where the mobility level information is used to indicate the level of mobility of the user terminal 20 in a preset time period.

In one embodiment, the method for acquiring the movement level information of the user terminal 20 in step S110 includes: acquiring mobility information of the user terminal 20, wherein the mobility information is data generated by the movement of the user terminal 20 among a plurality of access devices; and querying a preset mobility level mapping table according to the mobility information to obtain the mobility level information of the user terminal 20, where the mobility level mapping table is used to store a mapping relationship between the mobility information of the user terminal 20 and the mobility level information.

In an embodiment, the session establishment request sent by the user terminal 20 may specifically be a PDU session establishment request. Further, the executing subject of this step may be a session management device and a Network Data analysis device, specifically, the session management device may be an SMF, and the Network Data analysis device may be an NWDAF (Network Data analysis Function). When the PDU session establishment request is obtained, the mobility information of the ue 20 starts to be collected, where the mobility information is data generated by the ue 20 moving among several access devices. The SMF transmits an analysis request/subscription of the mobility Level information of the user terminal 20 to the NWDAF, and the NWDAF performs analysis to acquire and output the mobility Level information of the user terminal 20, so that, for example, an analysis result of High/Low/no (Level of UE mobility ═ High/Low/None) of the terminal mobility Level can be obtained. And it can be understood that, for the case of using NWDAF as the data analysis device, since an Output UE mobility level information is added, 23288 specification is required to be added to the NWDAF for the Output analysis setting of 6.7.2.3UE mobility analysis UE so as to be able to be used for the analysis and Output of the mobility level information of the user terminal 20. Meanwhile, a mobility level mapping table for indicating a mapping relationship between mobility information and mobility level information of the user terminal 20 needs to be newly added for NWDAF. Specifically, the mobility level mapping table mainly stores the mapping relationship between the mobility information and the mobility level information, and in a preferred embodiment, the mapping relationship between the number of handovers and the mobility level information, and the mapping relationship between the number of overlaps and the mobility level information may be included, and in other embodiments, the mapping relationship between other mobility information and the mobility level information may also be included, but is not limited to, this.

In an embodiment, for the mobility information, collecting mobility information of the user terminal 20 from OAM (Operation Administration and Maintenance), 5GC (5G Core Network ) and AF (Application Function) may be supported by the Network data analysis device, including collecting MDT (Minimization of Drive Test) data from OAM, collecting Network data from 5GC, and collecting traffic data from AF. Although the location information about the user terminal 20 may be obtained, since three paths are listed in the present embodiment, the granularity of the information obtained in each path is different: the position information provided by OAM contains longitude and latitude information; the position information provided by the 5GC contains TA or cell information; the location information provided by the AF contains geographical area information and thus can be used selectively on demand. Moreover, it can be understood that, since the above methods are all existing schemes, there are records in the 3GPP standard, and detailed description thereof is omitted. The key point of the present solution is to query a preset mobility level mapping table according to the mobility information to obtain the mobility level information of the user terminal 20.

In one embodiment, the mobility information includes the number of handovers of the user terminal 20 between tracking areas within a first preset time; the mapping relationship between the mobility information and the mobility level information of the user terminal 20 includes: when the switching times are smaller than a first preset value, the mobile level information is configured to be a first mobile level, and the first preset value is a preset integer; when the switching times are greater than or equal to a first preset value and less than or equal to a second preset value, configuring the mobility level information into a second mobility level; the second mobility level is higher than the first mobility level, and the second preset value is an integer larger than the first preset value; and when the switching times are larger than a second preset value, configuring the mobility level information into a third mobility level, wherein the third mobility level is higher than the second mobility level.

In an embodiment, it is understood that each access device forms a tracking area with its coverage area, when the user terminal 20 moves among a plurality of tracking areas, it will switch among the tracking areas, and at the same time, a switching record is generated and recorded by the mobility information, so the mobility information includes the number of times that the user terminal 20 switches among the plurality of tracking areas within a first preset time, and the first preset time can be arbitrarily set, which does not limit the invention. In the mobility level mapping table, the level of the mobility level of the user terminal 20 may be determined by the number of handovers of the user terminal 20. Specifically, in the present embodiment, the first preset value may be an integer set arbitrarily, and in a preferred embodiment, is an integer greater than or equal to 0; the second preset value is an integer greater than the first preset value. In the present embodiment, the first mobility level, the second mobility level, and the third mobility level are set to indicate the attribute that the mobility level of the user terminal 20 changes from none to low to high. However, it should be understood that, although the first and second stepwise differentiation methods are not intended to limit the technology, but are only specific examples for facilitating understanding of the solution, the practical situation may not be taken as a specific embodiment, and for example, the property characteristics of the user terminal 20 from lack of levelness to low levelness to high levelness may be further refined and dynamically expressed, for example, in a numerical manner.

In another embodiment, the mobility information includes the number of overlapping of the active area and the tracking area generated by the user terminal 20 due to movement within a second preset time; the mapping relationship between the mobility information and the mobility level information of the user terminal 20 includes: when the overlapping quantity is smaller than a third preset value, the movement level information is configured to be a first mobility level, and the third preset value is a preset integer; when the number of overlaps is greater than or equal to a third preset value and less than or equal to a fourth preset value, configuring the mobility level information as a second mobility level; the second mobility level is higher than the first mobility level, and the fourth preset value is an integer larger than the third preset value; and when the number of overlaps is greater than a fourth preset value, configuring the mobility level information to a third mobility level, the third mobility level being higher than the second mobility level.

In one embodiment, if the user terminal 20 moves, the moving track of the user terminal forms an area range, i.e. an active area. The active area and the tracking area formed by the coverage of several access devices overlap each other, so that the amount of overlap within the second preset time that is arbitrarily set is included in the mobility information, that is, the amount of overlap can be used to analyze the mobility level information of the user terminal 20. Referring to the embodiment based on the number of times of handover, in the present embodiment, the third preset value and the fourth preset value are also preset according to actual situations, so as to distinguish the mobility level of the ue 20 as a standard. The third preset value is a preset integer, the fourth preset value is an integer greater than the third preset value, and the first and second differences in mobility level are only for facilitating understanding of an attribute feature of the mobility level of the ue 20 from none to low to high, but not for limiting the technology. It should be noted that, the two ways of determining the mobility level information, i.e. the number of times of handover and the number of times of overlapping, are not isolated, but two parallel schemes, and actually, the two ways may work together to determine the mobility level information of the ue 20, and the same may also include other mapping relationships between the mobility information and the mobility level information in the mobility level mapping table to determine the mobility level information of the ue 20.

Step S120: and allocating corresponding forwarding devices to the user terminal 20 according to the movement level information, wherein the forwarding devices are used for realizing routing and forwarding of data of the user terminal 20.

In one embodiment, the method for allocating a corresponding forwarding device to the user terminal 20 according to the movement level information in step S120 includes: determining an available forwarding device set corresponding to the user terminal 20 according to the mobility information, where the available forwarding device set includes a forwarding device set capable of providing a service for the user terminal; when the mobility level information is a first mobility level, controlling the user terminal 20 to connect with one of a first forwarding device, a second forwarding device, and a third forwarding device in the available forwarding device set; when the mobility level information is a second mobility level, controlling the user terminal 20 to connect to one of a second forwarding device and a third forwarding device in the available forwarding device set; when the mobility level information is a third mobility level, the user terminal 20 is controlled to connect to a third forwarding device in the set of available forwarding devices.

In an embodiment, in this embodiment, the mobility levels are divided into a first, a second and a third, which show the order of the mobility levels of the user terminal 20 from low to high. The first mobility level may be understood in practice as a situation in which the user terminal 20 has no mobility; the second mobility level corresponds to the user terminal 20 being low mobility; and a third mobility level is the case when the user terminal 20 is of high mobility. And thus may correspond to allocating a forwarding device to the user terminal 20 that is appropriate to its level of mobility. In the distribution process, two layers of conditions need to be satisfied, the first layer is to satisfy the condition of correctly distributing the corresponding forwarding devices, that is, a plurality of selectable forwarding devices to be distributed can provide forwarding services for the user terminal 20, wherein a plurality of forwarding devices capable of providing forwarding services for the user terminal 20 are a collection of the forwarding devices, that is, an available forwarding device collection; the second layer is that the allocated forwarding devices are adapted to the mobility level of the user terminal 20. In particular, for appropriate meanings: in the preferred embodiment, the user terminal 20 is assigned a forwarding device that is peer to its mobility level, for example, in the present embodiment, the user terminal 20 of the first mobility level is assigned a first forwarding device, the user terminal of the second mobility level is assigned a second forwarding device, and the user terminal of the third mobility level is assigned a third forwarding device. In another embodiment, a higher-level forwarding device is allocated to the user terminal 20, for example, a second forwarding device or a third forwarding device may be allocated to the user terminal 20 with the first mobility level, and a third forwarding device may be allocated to the user terminal with the second mobility level. In other embodiments, it may also be a forwarding device that assigns a near or closest tier to the user terminal 20. For example, for the user terminal 20 with the third mobility level, it can only allocate a connection with the third forwarding device according to the aforementioned standard, and if there is no third forwarding device in its available forwarding device set, that is, if there is no forwarding device with the mobility level equal to or higher than that in the available forwarding device set, it can allocate a forwarding device with the mobility level closest to that of the available forwarding device set. Specifically, the user terminal 20 at the second mobility level may not have the second forwarding device or the third forwarding device in the corresponding available forwarding device set, and may be allocated to connect to the first forwarding device; for the available forwarding device set corresponding to the user terminal 20 with the third mobility level, if there is no third forwarding device, the forwarding device set may be preferentially connected to the second forwarding device in the available forwarding device set; the first forwarding device may be assigned to connect with the user terminal 20 if no second forwarding device is available from the set of available forwarding devices. It will be appreciated that for a forwarding device that assigns a close or closest tier to the user terminal 20, the forwarding device may not be able to meet the mobility level requirements of the user terminal 20, and therefore this embodiment is complementary to the solution of the present application and only performs when the conditions described above are met. It should be noted that, in the above three embodiments, the embodiment of assigning peers with mobility levels is preferred, and the alternative embodiment of assigning peers with mobility levels higher than that is preferred, but the available forwarding devices are not peers in the set or higher than that, so as to assign similar forwarding devices.

In an embodiment, an example is given to facilitate understanding, and also fig. 2 is taken as an example and the foregoing standard is continued, wherein a forwarding device 5 (not shown in the figure) may be further included, and the forwarding device 5 is connected to the access device 1 and the access device 3, so that the forwarding device 5 and the forwarding device 2 both belong to the second forwarding device. When allocating the corresponding forwarding devices to the user terminal 20, firstly, an available forwarding device set corresponding to the user terminal 20 should be determined according to the mobility information, that is, in the determining process, the determining process may be matching according to the determined activity range of the user terminal 20 and the tracking area corresponding to the access device, and firstly, a set of forwarding devices capable of providing services for the user terminal 20 is screened out. Taking fig. 2 as an example, if the user terminal 20 moves in the tracking area where the access device 1 and the access device 2 are connected, the corresponding switching times are in the range from the first preset value to the second preset value, and the overlapping number is in the range from the third preset value to the fourth preset value. First, an available forwarding device set corresponding to the user terminal 20 is determined, and known from the activity range included in the mobility information, the available forwarding device set corresponds to the tracking areas of the access device 1 and the access device 2, so that the available forwarding device set of the user terminal 20 includes the forwarding device 2 and the forwarding device 3, but does not include the forwarding device 1 or the forwarding device 5. Since the access device 2 is not included in the forwarding device 1 or the connected access device of the forwarding device 5, the forwarding service cannot be provided for the user terminal 20 even if the forwarding device 5 and the forwarding device 2 belong to the second forwarding device. And correspondingly allocating forwarding devices according to the mobility level of the user terminal 20, wherein the available forwarding device set includes the forwarding device 2 and the forwarding device 3, which respectively correspond to the second forwarding device and the third forwarding device, and since the number of times of switching of the user terminal 20 is in a range from zero to a first preset value and the number of overlaps is in a range from one to a fourth preset value, it can be obtained that the mobility level information corresponding to the user terminal 20 is configured as a second mobility level, and therefore, the forwarding device 2 of one of the second forwarding device and the third forwarding device in the available forwarding device set is finally selected for the user terminal 20 to be matched with the second mobility level, and the selection of the forwarding device is completed. That is, in the present embodiment, when allocating the forwarding device of the user terminal 20, it is first considered that the correct matching of the mobility information is performed so that the forwarding device can be correctly selected, and then considered that the forwarding device corresponds to the mobility level of the user terminal 20.

In an embodiment, the first forwarding device, the second forwarding device and the third forwarding device support forwarding for a fixed network or a mobile network simultaneously.

In one embodiment, in a preferred embodiment, the first forwarding device, the second forwarding device and the third forwarding device all support forwarding in a fixed network or a mobile network at the same time. In the preferred embodiment, it can be understood that the third forwarding device is preferably directed to the routing and allocation of the user terminal 20 with higher mobility level, so that the third forwarding device can support the session and service continuity guarantee of the SSC mode3 to guarantee the network quality of the user terminal 20 with high mobility level.

In an embodiment, as for an overall processing flow of the present embodiment, reference may be made to fig. 3, where fig. 3 is a timing diagram of a forwarding device selection method according to an embodiment of the present invention. As can be seen from the figure, based on the forwarding device selection method provided in this embodiment, the network data analysis device is configured to analyze and obtain the movement level information of the user terminal 20, so that the user terminal 20 selects a corresponding forwarding device. Specifically comprising steps S310-S360.

Step S310: the network data analysis equipment acquires mobility information of the user terminal.

Step S320: the user terminal sends a PDU session establishment request to the session management device.

Step S330: the session management device sends a movement level information acquisition request to the network data analysis device.

Step S340: and the network data analysis equipment acquires the mobility level information according to the mobility information.

Step S350: the network data analysis device provides the mobility level information to the session management device.

Step S360: and the session management equipment selects corresponding forwarding equipment for the user terminal according to the mobile level information.

The invention can intelligently allocate corresponding forwarding equipment to the user terminal according to the moving level of the user terminal, thereby reducing the generation of unnecessary signaling interaction caused by switching the user terminal between the forwarding equipment. Furthermore, in the forwarding device selection method provided in an embodiment of the present invention, different network accesses are configured for different forwarding devices, so that the forwarding devices accessed by user terminals with different mobility levels implement routing and forwarding of data by different networks. Through the setting, the forwarding equipment is selected according to the scene requirements and by combining the functions of the forwarding equipment, and the selection requirements of the forwarding equipment in the fixed-moving fusion scene are met.

Fig. 4 is a flowchart illustrating a method for selecting a forwarding device according to an embodiment of the present invention. For a clear description of the forwarding device selection method provided in an embodiment of the present invention, please refer to fig. 1 to fig. 4.

The present embodiment is mainly directed to the case that the mobility information includes the number of times of handover, and specifically may include the following steps S410 to S440.

Step S410: mobility information of the user terminal 20 is obtained, and the mobility information includes the number of times of switching between the tracking areas of the user terminal 20 within a first preset time.

In an embodiment, the mobility information is data generated by the user terminal 20 moving on each forwarding device, and the means and method for acquiring the mobility information are described in detail in the foregoing text, and are not described again in detail. Specifically, for the relationship between the user terminal 20 and the mobile terminal, it may be: the forwarding device is connected with the access device, the access device covers to form a tracking area, the user terminal 20 in the tracking area is connected with the forwarding device through the access device, the forwarding device comprises a first forwarding device, a second forwarding device and a third forwarding device, the movement level information supported by the third forwarding device is higher than that supported by the second forwarding device, and the movement level information supported by the second forwarding device is higher than that supported by the first forwarding device.

In one embodiment, the forwarding devices are distinguished in a first, second and third way, which are intended to indicate that there is a difference in the level of the movement level information supported by each of the forwarding devices of different classes. Wherein the third forwarding device supports higher mobility level information than the second forwarding device supports, and the second forwarding device supports higher mobility level information than the first forwarding device supports. The specific representation of the level of the mobility level information that can be supported by the forwarding device may be the number of access devices connected to the forwarding device, or the size of a covered tracking area, or the number of user terminals that can be simultaneously supported, and the like, and is not limited specifically. In this embodiment, the number of access devices connected to a forwarding device is taken as an example of a determination criterion for distinguishing a first forwarding device, a second forwarding device, and a third forwarding device. Specifically, the first forwarding device may be connected to a first number of access devices; the second forwarding equipment is connected with a second number of access equipment, and the second number is greater than the first number; the third forwarding devices are connected to a third number of access devices, the third number being greater than the second number. In the present embodiment, referring to fig. 2, as shown in fig. 2, in the present embodiment, the first number is set to 1, the second number is set to 2, and the third number is set to 3, which are only simple settings for easy understanding of the scheme, and in practical cases, the actual number only needs to satisfy that the second number is greater than the first number, and the third number is greater than the second number. When the user terminal 20 moves among the access equipment 1, the access equipment 2 and the access equipment 3 within the first preset time, switching is carried out among tracking areas of the access equipment, and each switching forms switching times and is recorded to the mobility information. Therefore, the level of the movement level information of the user terminal in the first preset time can be analyzed through the switching times, the first preset time can be set arbitrarily according to the practical situation, and the technical scheme of the invention is not limited.

Step S420: and when the switching times are smaller than a first preset value, configuring the mobility level information into a first mobility level, and controlling the user terminal 20 to be connected with one of the first forwarding device, the second forwarding device and the third forwarding device, where the first preset value is a preset integer.

Step S430: and when the switching times are greater than or equal to a first preset value and less than or equal to a second preset value, configuring the mobility level information into a second mobility level, and controlling the user terminal 20 to be connected with one of the second forwarding device and the third forwarding device, wherein the second mobility level is higher than the first mobility level, and the second preset value is an integer greater than the first preset value.

Step S440: and when the switching times are greater than a second preset value, configuring the mobility level information into a third mobility level, and controlling the user terminal 20 to be connected with a third forwarding device, wherein the third mobility level is higher than the second mobility level.

In one embodiment, for convenience of understanding, the first preset value is set to two, and the second preset value is set to five in this embodiment. It can be understood that, if the number of handovers in the mobility information of the user terminal 20 is less than the first preset value when the user terminal 20 is always located in the tracking area of one access device, the mobility level information of the user terminal 20 may be configured to be the first mobility level, and one of the corresponding first forwarding device, second forwarding device, and third forwarding device is selected for the user terminal 20 to be connected, specifically, for the first mobility level, the level is for the user terminal 20 with almost no mobility, for which, in a preferred embodiment, a forwarding device without access to a smaller number of access device connections is arranged, for example, as shown in fig. 2, if the user terminal 20 is located only in the tracking area of the access device 1, the first forwarding device is assigned. In other embodiments, a forwarding device with a higher or similar level of mobility than the first mobility, such as one of the second forwarding device or the third forwarding device, may be arranged to connect to the user terminal 20.

In other embodiments, if the ue 20 is moving all the time, and if the number of handovers satisfies the condition that the number of handovers is greater than or equal to the first preset value and less than or equal to the second preset value within the first preset time, for example, four times in total, the ue 20 may be configured to have a second mobility level, where the second mobility level may be a level that has mobility and is at least a handover between two access devices, but is in a low mobility case, a corresponding forwarding device may be allocated to the ue, that is, one of the second forwarding device and the third forwarding device that satisfies the condition.

In another embodiment, if the user terminal 20 moves frequently and the number of handovers exceeds the limit of the first preset condition 5 times within the first preset time, it may be determined that the user terminal 20 has higher mobility, and may be configured as the third mobility level information. And correspondingly selecting a third forwarding device simultaneously accessed with at least a third number of access devices to connect with the user terminal 20, so as to ensure the network connection continuity of the user terminal 20. Meanwhile, in order to meet the requirement of the high-mobility user terminal 20, the third forwarding device needs to support the session and service continuity guarantee of the SSC mode3, so as to guarantee the network quality of the high-mobility user terminal 20. It should be noted that, when the forwarding device is selected for the user terminal 20 according to the number of times of switching, all of the first forwarding device, the second forwarding device, and the third forwarding device need to be in an available forwarding device set corresponding to the user terminal 20, and the definition and the determination method for the available forwarding device set are described in detail in the foregoing, and are not described again here.

The invention can intelligently allocate corresponding forwarding devices to the user terminal 20 according to the moving level of the user terminal, thereby reducing the generation of unnecessary signaling interaction caused by switching the user terminal 20 between the forwarding devices. Furthermore, the method for selecting a forwarding device according to an embodiment of the present invention can determine the mobility level information of the user terminal 20 according to the number of times of handover, and ensure correct selection of the forwarding device by correctly and quickly determining the mobility level information.

Fig. 5 is a flowchart illustrating a method for selecting a forwarding device according to an embodiment of the present invention. For a clear description of the forwarding device selection method provided in an embodiment of the present invention, please refer to fig. 1-3 and fig. 5.

Step S510: and acquiring mobility information of the user terminal 20, wherein the mobility information comprises the overlapping quantity of the active area and the tracking area generated by the user terminal 20 due to movement in a second preset time.

In one embodiment, the forwarding devices are distinguished in a first, second and third way, which are intended to indicate that there is a difference in the level of the movement level information supported by each of the forwarding devices of different classes. Wherein the third forwarding device supports higher mobility level information than the second forwarding device supports, and the second forwarding device supports higher mobility level information than the first forwarding device supports. The concrete representation of the level of the mobility level information that can be supported by the forwarding device may be the number of access devices connected to the forwarding device, or the size of the covered tracking area, or the number of user terminals that can be supported at the same time, and the like, and is not limited in particular. In this embodiment, the number of access devices connected to a forwarding device is taken as an example of a determination criterion for distinguishing a first forwarding device, a second forwarding device, and a third forwarding device. Specifically, the first forwarding device may be connected to a first number of access devices; the second forwarding equipment is connected with a second number of access equipment, and the second number is greater than the first number; the third forwarding devices are connected to a third number of access devices, the third number being greater than the second number. In the present embodiment, referring to fig. 2, as shown in fig. 2, in the present embodiment, the first number is set to 1, the second number is set to 2, and the third number is set to 3, which are only simple settings for easy understanding of the scheme, and in practical cases, the actual number only needs to satisfy that the second number is greater than the first number, and the third number is greater than the second number. Specifically, each access device may form its own tracking area, a moving track formed by the user terminal 20 due to its movement may also form an active area within a second preset time, an overlapping phenomenon exists between the active area and the tracking area of each access device, and the number of overlaps forms mobility information and is recorded. Therefore, the number of overlapping between the activity area and the tracking area of each access device may also be used as a basis for analyzing and determining the movement level information of the user terminal 20, and the second preset time may be arbitrarily set according to the actual situation, which does not limit the technical solution of the present invention.

Step S520: and when the overlapping amount is smaller than a third preset value, configuring the mobility level information into a first mobility level, and controlling the user terminal 20 to be connected with one of the first forwarding device, the second forwarding device and the third forwarding device, where the third preset value is a preset integer.

Step S530: and when the number of overlaps is greater than or equal to a third preset value and less than or equal to a fourth preset value, configuring the mobility level information into a second mobility level, and controlling the user terminal 20 to be connected with one of the second forwarding device and the third forwarding device, where the second mobility level is higher than the first mobility level, and the fourth preset value is an integer greater than the third preset value.

Step S540: and when the number of overlaps is greater than a fourth preset value, configuring the mobility level information to a third mobility level, and controlling the user terminal 20 to connect with a third forwarding device, where the third mobility level is higher than the second mobility level.

In one embodiment, for convenience of understanding, the third preset value is set to 2 and the fourth preset value is set to 3 in this embodiment. Also in the scenario embodied in fig. 2, it can be understood that if the ue 20 is always located in the tracking area of one access device, the number of overlaps between the active area and the tracking area is always one in the second preset time. The mobility level information of the ue 20 may be configured to be a first mobility level, and one of the corresponding first forwarding device, second forwarding device and third forwarding device may be selected for the ue 20 to connect, specifically, for the first mobility level is a level for the ue 20 with almost no mobility, and for this, the corresponding forwarding device is arranged, that is, as described above, the forwarding device is matched with the mobility level, such as the first forwarding device; or higher than the first forwarding device, such as the second forwarding device and the third forwarding device, and may also be similar forwarding devices.

In other embodiments, if the user terminal 20 moves, and enters the tracking area of the access device 2 within the second preset time, the number of overlaps between the active area and the tracking area is 2, and the conditions that the number of overlaps is greater than or equal to the third preset value and less than or equal to the fourth preset value are met. That is, the user terminal 20 may be configured to the second mobility level. The specific meaning of the second mobility level may then be that the corresponding has mobility, but in case of low mobility, it may be assigned a corresponding forwarding device, i.e. one of the second forwarding device or the third forwarding device that satisfies the condition.

In another embodiment, if the ue 20 moves more frequently, and overlaps with the tracking areas of a total of three access devices within the second preset time, and the number of the overlapping satisfies the condition that the number is greater than the fourth preset value, it may be determined that the ue 20 has higher mobility, and may be configured as the third mobility level information. And correspondingly selects a third forwarding device supporting a third mobility level to connect with the user terminal 20, so as to ensure the network connection continuity of the user terminal 20. Meanwhile, in order to meet the requirement of the high-mobility user terminal 20, the third forwarding device needs to support the session and service continuity guarantee of the SSC mode3, so as to guarantee the network quality of the high-mobility user terminal 20. It should be noted that, when the forwarding device is selected for the user terminal 20 according to the overlapping amount, all of the first forwarding device, the second forwarding device, and the third forwarding device need to be in an available forwarding device set corresponding to the user terminal 20, and the definition and the determination method for the available forwarding device set are described in detail in the foregoing, and are not described again here.

The invention can intelligently allocate corresponding forwarding devices to the user terminal 20 according to the moving level of the user terminal, thereby reducing the generation of unnecessary signaling interaction caused by switching the user terminal 20 between the forwarding devices. Furthermore, the method for selecting a forwarding device according to an embodiment of the present invention can also determine the movement level information of the user terminal 20 according to the overlapping amount, and ensure the correct selection of the forwarding device by correctly and quickly determining the movement level information.
