Detailed Description

The technical solution in the present application will be described below with reference to the accompanying drawings.

The identification of 5G terminals is crucial to the development of communication technology. In general, the terminal network capability can be identified by a terminal library matching method. Specifically, the network side may identify whether the terminal supports the 5G network according to a static terminal Type Allocation Code (TAC). However, since the TAC on the network side is not updated in time, there may be a terminal TAC that is not recorded in the TAC on the network side, so that the 5G terminal is not identified, and a corresponding 5G network cannot be provided for the terminal TAC.

The embodiment of the application provides a method for identifying a 5G terminal, which determines whether the terminal is the 5G terminal according to User Equipment Network Capability (UENC) in a signaling between the terminal and network equipment so as to accurately identify the 5G terminal. And further identifying the support capability of the 5G terminal to an independent networking (SA) and a non-independent Networking (NSA) respectively according to the field in the UENC, so that a network service adapted to the network capability of the terminal can be provided for the terminal in two different networking modes, namely SA and NSA.

For facilitating understanding of the embodiment of the present application, first, a network architecture suitable for the identification method of the 5G terminal provided in the present application is described in detail with reference to fig. 1. As shown in fig. 1, the network architecture 100 may include a terminal 110, an access network device 120, and a core network device 130. Wherein, the terminal 110 may communicate with the core network device 130 through the access network device 120. For example, the terminal 110 may send an attach request (attach request) message or a tracking area update request (TAU request) message to the core network device 130 through the access network device 120.

The access network device may forward the message to the core network device through an interface with the core network device. Illustratively, the core network device 130 may be a Mobility Management Entity (MME) in the 4G network, and the connection interface of the access network device 120 and the core network device 130 may be an S1-MME interface in the 4G network.

It should be understood that the illustration in the drawings is merely an example, and the application does not limit the number of access network devices connected to the core network device in the network architecture, nor the number of terminals within the coverage area of the access network device. In addition, the core network device may be an MME in a 4G network, or may be a device that can be used to implement a mobility management function in a 5G network, such as an access and mobility management element (AMF), and an interface between an access network device and the core network device corresponding to the core network device may also be an N2 interface in the 5G network. Embodiments of the present application include, but are not limited to, the following.

For ease of understanding, the method provided by embodiments of the present application is described below in conjunction with the architecture shown in fig. 1. It should be understood that the method illustrated in fig. 2 may be performed at a core network device (e.g., an MME in a 4G network).

The method for identifying the 5G terminal provided in the embodiment of the present application will be described in detail below with reference to fig. 2.

It should be noted that, in the embodiment of the present application, for convenience of description, when referring to numbering, for example, numbering of bytes, bits, and the like, consecutive numbering may be performed from 1. Of course, the specific implementation is not limited thereto, and for example, the numbers may be consecutively numbered from 1. It should be understood that the above descriptions are provided for convenience of describing the technical solutions provided by the embodiments of the present application, and are not intended to limit the scope of the present application.

Fig. 2 is a schematic flowchart of an identification method 200 of a 5G terminal according to an embodiment of the present application. As shown in fig. 2, the method 200 may include steps 210 through 230.

In step 210, the core network device obtains a target signaling according to the signaling record of the terminal, where the target signaling includes the UENC.

Specifically, the core network device may obtain a target signaling containing the UENC according to the signaling record of the terminal. Wherein the UENC may be used to indicate the network capabilities of the terminal.

As an example, the target signaling is an attach request message. The terminal may send an attach request message to the radio access network device, which may send the attach request message to the core network device. The attach request message includes an Information Element (IE) of the UENC.

As another example, the target signaling is a tracking area update request message. For example, if the location of the terminal changes, the terminal may send a tracking area update request message to the core network device through the access network device, where the tracking area update request message may include the UENC IE.

The signaling record of the terminal may be obtained from an external data representation (XDR) detail set of the signaling external data of the terminal. For example, the core network device (e.g., MME) may perform Deep Packet Inspection (DPI) on traffic of an interface (e.g., S1-MME) between the access network device and the core network device, search for a signaling flow record of a target signaling (e.g., the above attachment request or the tracking area update request), and obtain a corresponding target signaling.

Fig. 3 shows a partial schematic diagram of the UENC. As shown in fig. 3, the UENC includes 15 bytes (octets), such as the 1 st byte through the 15 th byte shown in the figure. Each byte comprises 8 bits, and the 8 bits are the 1 st bit to the 8 th bit in sequence from right to left.

For the convenience of understanding the embodiment of the present application, fig. 3 shows specific contents of the 1 st byte, the 2 nd byte, and the 5th bit and the 6 th bit in the 9 th byte in the UENC.

Wherein, the 1 st byte of the UENC is UENC IE identity (UENC IE identifier, UENC IEI), which may be used to indicate that this IE is UENC IE. The 2 nd byte indicates the UENC content length (length of UENC contents), which may be referred to as a UENC content length field. Bytes 3 to 15 indicate a value of the UENC, and may be referred to as a value field of the UENC.

A 5th bit in a 9 th byte (also referred to as a 7 th byte of a value of the UENC) of the UENC is a dual connectivity with a New Radio (NR) and a 6 th bit is an N1 interface mode (N1 mode).

It should be understood that other contents in the UENC IE are not shown in the figure, but do not represent other bytes and bits as empty. The content of other bytes and bits in the UENC IE is not limited in the present application.

In step 220, the core network device determines whether the terminal is a 5G terminal according to the UENC.

Since it is defined in the protocol that the UENC IE content of a 5G terminal may comprise at least 7 bytes, the terminal may be determined to be a 5G terminal in case it is determined based on the UENC that the UENC content occupies an overhead of greater than or equal to 7 bytes.

One possible implementation is that in case the length indicated in the UENC content length field is greater than or equal to 7 bytes, the core network device may determine that the terminal is a 5G terminal.

This UENC content length field is the 2 nd byte in the UENC described above in connection with fig. 3. This byte may be used to indicate the length of the UENC content, i.e., the length of the value field (e.g., bytes 3 through 15 in fig. 3) of the UENC. Another possible implementation is that, when the UENC is expressed in hexadecimal, the core network device may determine that the terminal is a 5G terminal in a case where the number of bits of the value field of the UENC is greater than or equal to 14 bits.

Since each byte may include an 8-bit binary number, the value field of the UENC shown in fig. 3 may have a total of 56-bit binary numbers, i.e., 14-bit hexadecimal numbers.

Therefore, when the UENC is represented by a hexadecimal number, the core network device may determine that the terminal is a 5G terminal if the value field of the UENC is greater than or equal to 14 bits.

It should be understood that the above listed implementation manners for identifying the 5G terminal are only examples, and should not constitute any limitation to the present application. For example, when the UENC is represented by a binary number, whether the terminal is a 5G terminal may be determined according to the bit number of the value field of the UENC.

The method for identifying the 5G terminal provided in the embodiment of the present application can determine whether the terminal is the 5G terminal or not by the length of the value field of the UENC in the signaling between the terminal and the network. The situation that some 5G terminals accessing the network are not identified due to untimely updating of the TAC can be avoided, so that corresponding network services can be provided for the 5G terminals, and bad experience brought to users due to the fact that 5G network services are not provided for the 5G terminals in the 5G network is avoided.

Further, since the 5G network currently includes an independent networking SA and a non-independent networking NSA, the core network device may further recognize the support capability of the 5G terminal for the SA and the NSA.

In step 230, the core network device determines the support capability of the 5G terminal for SA and NSA according to the UENC.

As mentioned above, the 9 th byte of the UENC, that is, the 7 th byte of the value field of the UENC, contains the capability information whether the terminal supports the 5G network. As shown in fig. 3, bit 5 DCNR in byte 9 of UENC may be used to indicate whether the terminal supports NR dual connectivity. DCNR ═ 1 may indicate that the terminal has 5G NSA access capability; DCNR ═ 0 may indicate that the terminal does not have 5G NSA access capability. The 6 th bit N1mode indicates whether the terminal supports the N1 interface. N1mode — 1 may indicate that the terminal has 5G SA access capability; n1mode — 0 may indicate that the terminal does not have 5G SA access capability.

It can be seen that the terminal's support capability for SA and NSA can be determined based on the 5th bit and the 6 th bit in the 9 th byte of the UENC.

The core network device may further determine, according to the N1mode and the DCNR, that a 5G network switch of the terminal is turned on, when the terminal is determined to be a 5G terminal. Illustratively, the value of at least one of the DCNR and the N1mode is 1, which may indicate that the 5G network switch of the terminal is turned on. If the hexadecimal number is converted to indicate that the hexadecimal number is the 14 th (which can correspond to the 5th bit to the 8 th bit of the value field of the UENC) hexadecimal number of the value field of the UENC, the hexadecimal number is any one of {1, 2, 3, 5, 6, 7, 9, a, B, D, E, F }, and can indicate that the terminal has 5G network access capability.

Note that the hexadecimal number is counted from 1. If the counting is started from 0, the value is the 13 th hexadecimal number of the value field of the UENC. There may be a number of situations when the terminal supports 5G and the 5G network switch is open. The first possible case is that the terminal supports a 5G network and supports SA and NSA; the second possible case is that the terminal supports 5G network and NSA, not SA; a third possible scenario is that the terminal supports 5G networks and SA, not NSA. These are described in detail below.

In a first possible case, if the 14 th hexadecimal number of the value field of the UENC is one of 3, 7 and B, F, it is determined that the terminal supports SA and NSA.

Illustratively, the

hexadecimal numbers

3, 7 and B, F are represented as 0011, 0111, 1011 and 1111 in binary, and it is understood that the two subsequent digits of 3, 7 and B, F after binary are all 11, i.e. the 5th bit DCNR in the 9 th byte of the UENC is 1 and the 6 th bit N1mode is 1. Therefore, when the 14 th hexadecimal number of the value field of the UENC is one of 3, 7 and B, F, the terminal supports a 5G network and supports SA and NSA.

In a second possible case, if the 14 th hexadecimal number of the value field of the UENC is one of 1, 5, 9 and D, it is determined that the terminal supports NSA and does not support SA.

Illustratively,

hexadecimal numbers

1, 5, 9 and D are represented as the binary numbers 0001, 0101, 1001 and 1101 respectively, and it is understood that the two digits after 1, 5, 9 and D are represented as the binary numbers are 01, that is, the 5th bit DCNR in the 9 th byte of the UENC is 1, and the 6 th bit N1mode is 0. Therefore, when the 14 th hexadecimal number of the value field of the UENC is one of 1, 5, 9 and D, at this time, the terminal supports a 5G network and supports NSA, and does not support SA.

In a third possible case, if the 14 th hexadecimal number of the value field of the UENC is one of 2, 6 and A, E, it is determined that the terminal supports SA and does not support NSA.

Illustratively, the hexadecimal numbers 2, 6 and A, E are represented as 0010, 0110, 1010 and 1110 respectively, and it is understood that 2, 6 and A, E are represented as 10 after the binary, that is, the 5th bit DCNR in the 9 th byte of the UENC is 0 and the 6 th bit N1mode is 1. Therefore, when the 14 th hexadecimal number of the value field of the UENC is one of 2, 6 and A, E, at this time, the terminal supports a 5G network and an SA, and does not support NSA.

Therefore, according to the identification method of the 5G terminal provided in the embodiment of the present application, when the terminal accessing the network is the 5G terminal, the support capability of the 5G terminal for the SA and the NSA may be further determined based on the value taking terminal of the UENC, so that the terminal may access the network adapted to the network capability of the terminal in two different networking modes, namely, the SA and the NSA.

For convenience of understanding, fig. 4 shows another schematic flowchart of the identification method of the 5G terminal provided in the embodiment of the present application.

As shown in fig. 4, in step 401, the core network device obtains a signaling record of a terminal of a next access network from a signaling XDR detail set. The signaling record of the terminal accessing the network may include signaling fields such as a procedure type, a subscriber number, an International Mobile Equipment Identity (IMEI), and a UENC.

Wherein the process type determines the elements and resources supported, and the method of allocating the process.

A cell phone number is a number used to uniquely identify a mobile user.

The IMEI, i.e. the serial number of the mobile phone, is used to identify the mobile communication device of each individual mobile phone in the mobile phone network, which is equivalent to the identity card of the mobile phone.

In step 402, the core network device reads the UENC in the signaling record of the terminal.

In step 403, the core network device reads the UENC content length, i.e. the 2 nd byte of the UENC.

In step 404, the core network device determines whether the terminal is a 5G terminal according to whether the UENC content length is greater than or equal to 7 bytes.

If so, step 405 may be executed to mark the terminal as a 5G terminal.

If not, step 414 may be performed.

In step 406, the core network device reads the value field of the UENC.

In step 407, the core network device reads the 14 th hexadecimal number of the value field of the UENC, and records the hexadecimal number as X.

In step 408, it is determined whether X belongs to one of {3, 7, B, F }. If yes, go to step 409, record the 5G terminal as supporting both SA and NSA, and store the subscriber number of the 5G terminal in set S1; if not, go to step 410.

In step 410, it is determined whether X belongs to one of {1, 5, 9, D }. If yes, go to step 411, mark the 5G terminal as supporting only NSA, and store the subscriber number of the 5G terminal in set S2; if not, go to step 412.

In step 412, it is determined whether X belongs to one of {2, 6, A, E }. If yes, go to step 413, mark the 5G terminal as supporting only SA, and store the subscriber number of the 5G terminal in the set S3; if not, go to step 414.

In step 414, it is determined whether the signaling XDR detail set is empty. If yes, ending; if not, the above steps are repeated from step 401.

Based on the above scheme, the core network device may determine whether the terminal accessing the network is a 5G terminal according to the UENC, and may further determine the support capability of the 5G terminal for the SA and the NSA. Therefore, the network equipment can accurately identify the 5G terminal and the non-5G terminal, and can provide services adaptive to the network capability of the terminal according to the support capability of the 5G network of the terminal.
