[0002] Generally, in order to improve user experience, when providing services to users, differentiated services can be provided to users in a targeted manner based on the needs of different user groups or the network capabilities of the user terminals used by users; in order to provide differentiated services to users, a policy and charging rules function (PCRF) is introduced into the network. For example, when promoting information marketing related to the fifth generation wireless systems (5G) technology to users, PCRF can be used to identify whether the user terminal supports 5G, so that promotion information is only sent to user terminals that support 5G, etc.;

[0003] In the prior art, when using PCRF to identify whether a user terminal supports 5G, it is usually necessary to manually configure the International Mobile Equipment Identity (IMEI) information of the terminal that supports 5G in the PCRF; in this way, when the user goes online, the PCRF determines whether the IMEI information of the user device exists in the manually configured 5G IMEI information, and then determines that the user device supports the 5G network, so that the corresponding information can be promoted to the user, or, based on this identification method, the terminals that support the 5G network are counted, etc. However, in order to identify network capabilities in this way, the IMEI information of the user terminal needs to be configured in the PCRF. The diversity of terminal manufacturers makes it difficult for the network to obtain the IMEI information of all terminals, and it is a manual configuration, and real-time performance is also difficult to guarantee.

[0004] Therefore, the method for identifying the network capability of a terminal in the prior art has the problem of being unable to accurately and timely identify the network capability of a user terminal. Summary of the invention

[0034] In order to enable those skilled in the art to better understand the technical solutions in the present invention, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work should fall within the scope of protection of the present invention.

[0035] Figure 1 A schematic diagram of an application scenario of the method for identifying the network capability of a user equipment provided by an embodiment of the present invention, such as Figure 1 As shown, the schematic diagram of the application scenario includes a user equipment, a mobility management entity (MME), a system architecture evolution gateway (SAEGW), and a PCRF; information is transmitted between the MME and the SAEGW via an S11 interface, and information is transmitted between the SAEGW and the PCRF entity via an Rx interface; in order to enable the user equipment to transmit its own network capability information to the PCRF so that the PCRF can identify the network capability of the user equipment; in an embodiment of the present invention, an information element for carrying network capability information is added to the interface message of the S11 interface, and the network capability information of the user equipment is transmitted to the SAEGW through the information element, and, in the interface message of the Rx interface, an information element for carrying network capability information is added, and the network capability information received by the SAEGW is transmitted to the PCRF through the information element;

[0036] In a specific implementation, when the network capability of the user equipment changes, the user equipment sends its latest network capability information to the MME. The MME carries the message in a newly added information element of the S11 interface message and sends it to the SAEGW. After receiving the interface message sent by the MME, the SAEGW obtains the network capability information of the user equipment from the interface message, and carries it in a newly added information element of the Rx interface message and sends it to the PCRF. In this way, after receiving the interface information sent by the SAEGW, the PCRF obtains the network capability information of the user equipment from the interface message, parses the network capability information, and thereby identifies the network capability of the user equipment based on the parsed information.

[0037] Among them, in a specific application scenario, identifying the network capability of the user equipment can be to identify whether the user equipment supports the 5G network, so as to realize the statistics of 5G network users, or realize the marketing of 5G network users, such as pushing 5G related information to 5G network users, etc. Of course, here is only an exemplary list of a specific application scenario of the method provided in the embodiment of the present invention, in addition to this, it can also be other, and the embodiment of the present invention is not limited to this.

[0038] Figure 2 The first flow chart of the method for identifying the network capability of a user equipment provided by an embodiment of the present invention is provided, wherein the method is applied to SAEGW, that is, the execution subject of the method is SAEGW, and specifically, the execution subject of the method can be a network capability device of the user equipment installed on SAEGW. Figure 2 As shown, the method comprises at least the following steps:

[0039] Step 102, obtaining a CSR message for the target user equipment sent by the MME; wherein the CSR message is additionally provided with an information element for carrying the network capability information of the target user equipment, and the network capability information includes the MS network capability information and / or the UE network capability information;

[0040] Step 104, determine whether the CSR message carries network capability information; if so, execute step 106; otherwise, end.

[0041] Step 106: The network capability information is carried in an information element added to the CCR-I message and sent to the PCRF, so that the PCRF identifies the network capability of the target user equipment according to the network capability information.

[0042] The user equipment mentioned above may be a terminal device such as a mobile phone, a tablet computer or a personal computer.

[0043] Specifically, in the embodiment of the present invention, the MME and the SAEGW transmit messages through the S11 interface. In order to enable the network capability information of the user equipment to be transmitted to the SAEGW, it is necessary to improve the interface message sent by the MME to the SAEGW through the S11 interface, that is, to add an information element for carrying the network capability information of the user equipment to the interface message. In this way, when the network capability information needs to be transmitted, it is only necessary to carry the network capability information in the information element added to the interface message, so as to be carried in the interface message and sent to the SAEGW.

[0044] Optionally, in a specific implementation manner, each time the user device attaches to the network, the network capability information of the user device may change. Therefore, each time the user device attaches to the network, the user device reports its latest network capability information to the MME. In order to send the network capability information of the user device to the SAEGW, the MME adds an element in the Create Session Request (CSR) message in advance, and carries the network capability information of the user device in the element added to the CSR message and sends it to the SAEGW.

[0045] It should be noted that, in the embodiment of the present invention, the network capability information reported by the user equipment may be the network capability information of the mobile station (MS); or the network capability information of the user equipment (UE); or, the network capability information includes both the MS network capability information and the UE network capability information; specifically, the information element added in the CSR message for carrying the network capability information of the target user equipment may be one, that is, the MS network capability information and the UE network capability information are carried in one information element; of course, the information element added in the CSR message for carrying the network capability information of the target user equipment may also be two, that is, one information element is used to carry the MS network capability information, and one information element is used to carry the UE network capability information;

[0046] Optionally, in a specific implementation, when the user equipment is performing network attachment, the user equipment sends a network attachment request to the MME, and the user equipment carries its latest network capability information in the network attachment request and sends it to the MME; when the MME receives the network attachment request, it obtains the network capability information of the user equipment from the network attachment request; and carries the network capability information in an information element added to the CSR message, that is, the network capability information is carried in the CSR message and sent to the SAEGW;

[0047] When SAEGW receives the CSR message sent by MME, it determines whether the CSR message carries the network capability information of the user equipment. If so, it obtains the network capability information of the target user equipment from the CSR message and sends the network capability information to PCRF in the interface message between SAEGW and PCRF.

[0048] Optionally, in a specific implementation, SAEGW and PCRF transmit messages via the Rx interface. In order to transmit the network capability information of the target user equipment from SAEGW to PCRF, it is necessary to modify the interface message sent by SAEGW to PCRF via the Rx interface, that is, to add a cell in the interface message for carrying the network capability information of the user equipment. In this way, the network capability information to be transmitted is carried in the cell added to the interface message, and is thus carried in the interface message and sent to PCRF. Of course, since the network capability information of the target user equipment includes UE network capability information and / or MS network capability information, in a specific implementation, two cells may be added to the interface message corresponding to the Rx interface, wherein one cell is used to carry the UE network capability information and the other cell is used to carry the MS network capability information. Alternatively, only one cell may be added to the interface message corresponding to the Rx interface to carry the MS network capability information and the UE network capability information. The embodiments of the present invention are not limited to this.

[0049] When the user equipment attaches to the network, the interface message for message transmission between the SAEGW and the PCRF may be an initial credit control response request (CCR-I) message, that is, an information element for carrying the network capability information of the user equipment is added to the CCR-I message.

[0050] Therefore, in a specific implementation, when SAEGW determines that the CSR message sent by the MME carries the network capability information of the user equipment, it obtains the network capability information of the user equipment from the CSR message, and carries the network capability information in the information element added to the CCR-I message, thereby carrying it in the CCR-I message to the PCRF.

[0051] When the PCRF receives the CCR-I message sent by the SAEGW, it obtains the network capability information of the target user device from the CCR-I message, parses the network capability information, and identifies the network capability of the user device according to the bit identifier of a certain byte in the parsed network capability information. For example, in a specific implementation, the bit identifier of a certain byte in the network capability information indicates the network capability information of the user device, such as whether it supports 5G, etc. Therefore, by parsing the obtained network capability information and obtaining the bit identifier of the corresponding byte, the network capability of the user device can be identified; of course, which byte bit identifier in the specific network capability information represents the network capability information of the user device can be analyzed according to the specific scenario, and the embodiment of the present invention does not limit this.

[0052] Optionally, in a specific implementation, SAEGW represents the UE network capability information in the form of attribute value pairs (AVP), represents the MS network capability information in the form of AVP, and carries the AVP UE network capability information and the AVP MS network capability information in a CCR-I message and sends it to PCRF.

[0053] The method for identifying the network capability of a user equipment provided by an embodiment of the present invention adds an information element for carrying the network capability information of the user equipment in a CSR message and a CCR-I message, so that when the user equipment performs network attachment, the MME can carry the network capability information of the user equipment in the information element added in the CSR message and send it to the SAEGW. After receiving the network capability information sent by the MME, the SAEGW carries the network capability information in the information element added in the CCR-I message and sends it to the PCRF. That is, the method provided by an embodiment of the present invention improves the interface messages between the MME and the SAEGW, and between the SAEGW and the PCRF, and adds an information element for carrying the network capability information of the user equipment in the interface messages, so that the network capability information of the user equipment can be transmitted as the user equipment attaches to the network. The method provided by the embodiment of the present invention eliminates the need to manually configure the network capability of the user device in the PCRF, thereby enabling the PCRF to automatically acquire the network capability information, thus saving time and effort. When the network capability information of the user device changes, the latest network capability information of the user device can be acquired in time, and the PCRF can adapt to the continuous changes in the network capability of the user device, thereby enabling the PCRF to timely, accurately and efficiently identify the network capability of the user device and timely grasp the changes and developments in the network capability of the user device.

[0054] Optionally, in a specific implementation, when the user equipment is not attached to the network, the network capability information may be updated, that is, the network capability may also change during the session period after the network attachment is performed; the network capability information that has changed during the session period may be triggered to be reported to the PCRF by the PCRF sending a trigger instruction; therefore, in order to enable the PCRF to obtain the latest network capability information of the user equipment in a timely and accurate manner, in an embodiment of the present invention, after the SAEGW carries the network capability information in the information element added by the CCR-I message and sends it to the PCRF, the method provided by the embodiment of the present invention further includes the following steps:

[0055] Detect whether a network capability change reporting event trigger instruction (trigger NETWORK_CAPABILITY_CHANGE) issued by PCRF is received; if so, after obtaining the current network capability information of the target user equipment after the change, the current network capability information is carried in the information element added to the update credit control response request (update credit control request, CCR-U) message and sent to the PCRF; wherein the above-mentioned network capability change reporting event trigger instruction is used to trigger the execution of the reporting operation of the current network capability information when a network capability change event of the target user equipment occurs.

[0056] In each session period (a session period can be understood as the time between the current network attachment and the next network attachment), when the network capability information of the target user equipment changes, the target user equipment reports its latest network capability information to the MME.

[0057] Optionally, in a specific implementation manner, the SAEGW obtains the current network capability information of the target user equipment after the change through the following steps:

[0058] Obtain a modify bearer request (MBR) message for a target user equipment sent by an MME; wherein the MBR message is supplemented with an information element for carrying network capability information of the target user equipment; determine whether the MBR message carries the network capability information; if so, obtain the network capability information from the MBR message as the current network capability information.

[0059] Optionally, in a specific implementation, when the MME receives the current network capability information reported by the target user device, the current network capability information is carried in the information element added to the MBR message, thereby carrying the information in the MBR message to the SAEGW; when the SAEGW receives the MBR message sent by the MME, it determines whether the MBR message carries the network capability information. If so, the network capability information of the user device is obtained from the MBR message and used as the current network capability information of the target user device.

[0060] Of course, in the specific implementation, whether SAEGW reports the received network capability information to PCRF depends on whether SAEGW receives the network capability change reporting event trigger instruction issued by PCRF, wherein the network capability change reporting event trigger instruction is used to trigger SAEGW to report the network capability change information of the target user equipment to PCRF.

[0061] In the specific implementation, after SAEGW obtains the current network capability information of the target user equipment after the change, it detects whether it has received the network capability change reporting event triggering instruction issued by PCRF. If the detection result indicates that SAEGW has received the network capability change reporting event triggering instruction issued by PCRF, it reports the obtained current network capability information of the target user equipment to PCRF;

[0062] Specifically, when SAEGW reports the current network capability information of the target user equipment to PCRF, it may carry the current network capability information of the target user equipment in the information element added to the CCR-U message, and then carry it in the CCR-U message and send it to PCRF.

[0063] That is, in the embodiment of the present invention, when the target user equipment performs network attachment, after receiving the network attachment request sent by the target user equipment (wherein the network attachment request carries the current network capability information of the target user equipment), the MME obtains the current network capability information of the target user equipment from the network attachment request, and carries the network capability information in the newly added information element of the CSR message and sends it to the SAEGW; after receiving the CSR message sent by the MME, the SAEGW obtains the current network capability information of the target user equipment from the CSR message, carries the obtained current network capability information in the information element added by the CCR-I message, and sends it to the PCRF, so that the PCRF obtains the current network capability information of the target user equipment from the CCR-I message, parses the current network capability information, and identifies the network capability of the target user equipment based on the bit identifier of a certain byte in the parsed current network capability information;

[0064] Of course, after the target user equipment attaches to the network (that is, within each session cycle after the network attachment), when the network capability information of the target user equipment changes, the target user equipment sends its latest network capability information (that is, the current network capability information) to the MME; when the MME receives the current network capability information sent by the target user equipment, it carries the current network capability information in the information element added by the MBR message and sends it to the SAEGW; when the SAEGW receives the MBR message sent by the MME, it obtains the current network capability information of the target user equipment from the MBR message, and at the same time detects whether it has received the network capability change reporting event trigger instruction issued by the PCRF within the session cycle; if the detection reception indicates that the network capability change reporting event trigger instruction issued by the PCRF has been received, the obtained current network capability information is carried in the information element added by the CCR-U message and sent to the PCRF, so that the PCRF obtains the current network capability information of the target user equipment from the CCR-U message, parses the current network capability information, and identifies the network capability of the target user equipment based on the bit identifier of a byte in the parsed current network capability information.

[0065] The method provided by the embodiment of the present invention can report the network capability information of the user equipment when the user equipment is attached to the network. When the network capability information of the user equipment changes when the user equipment is not attached to the network, the network capability information of the user equipment is also reported, so that the PCRF can fully and accurately grasp the changes in the network capabilities of the user equipment.

[0066] Optionally, in a specific implementation manner, the network capability information of the target user equipment includes MS network capability information and UE network capability information, and a first information element for the user to carry the MS network capability information and a second information element for carrying the UE network capability information are added to the CCR-I message; accordingly, the network capability information is carried in the information element added to the CCR-I message, specifically including:

[0067] The MS network capability information is carried in the first information element of the CCR-I message, and the UE network capability information is carried in the second information element of the CCR-I message.

[0068] That is, in one implementation mode, two information elements for carrying network capability information are added to the CCR-I message, which are called the first information element and the second information element; in this way, the first information element in the network capability information of the target user equipment is used to carry the UE network capability information, and the second information element is used to carry the MS network capability information. Of course, the first information element may also be used to carry the MS network capability information, and the second information element may be used to carry the UE network capability information.

[0069] Correspondingly, two information elements for carrying the network capability information of the target user equipment also need to be added to the CCR-U message, wherein one information element carries the UE network capability information and the other information element carries the MS network capability information.

[0070] That is, in an embodiment of the present invention, two information elements are added to the Rx interface message to carry the MS network capability information and the UE network capability information respectively; of course, only one information element may be added to the Rx interface message to carry the MS network capability information and the UE network capability information; when implemented, one or two information elements may be added according to the actual application scenario, and the embodiment of the present invention is not limited to this.

[0071] In the embodiment of the present invention, the MME and SAEGW are connected via the S11 interface, that is, messages are transmitted between the MME and SAEGW via the S11 interface; the SAEGW and PCRF are connected via the Rx interface, that is, messages are transmitted between the SAEGW and PCRF via the Rx interface.

[0072] Optionally, in the embodiment of the present invention, the information element added to the interface message of the S11 interface also carries the length of the network capability information; correspondingly, the information element added to the interface message of the Rx interface also carries the length of the network capability information;

[0073] In a specific implementation, the above network capability information includes MS network capability information and UE network capability information; accordingly, the information element added to the CSR message also carries the information length of the MS network capability information and the information length of the UE network capability information.

[0074] That is, in an embodiment of the present invention, in addition to sending the network capability information of the target user equipment to SAEGW, the MME also carries the information length of the network capability information in the information element added to the CSR message and sends it to SAEGW; similarly, after receiving the network capability information sent by the MME, the SAEGW carries the information length of the UE network capability information in the information element added to the CCR-I message for carrying the UE network capability information, and carries the information length of the MS network capability information in the information element added to the CCR-I message for carrying the MS network capability information.

[0075] Of course, in each session cycle, the information element added to the MBR message also carries the information length of the MS network capability information and the information length of the UE network capability information;

[0076] That is, in an embodiment of the present invention, in addition to sending the network capability information of the target user to SAEGW, the MME also carries the information length of the network capability information in the information element added to the MBR message and sends it to SAEGW; similarly, after receiving the network capability information sent by the MME, the SAEGW carries the information length of the UE network capability information in the information element added to the CCR-U message for carrying the UE network capability information, and carries the information length of the MS network capability information in the information element added to the CCR-U message for carrying the MS network capability information.

[0077] The method provided by the embodiment of the present invention adds an information element for carrying the network capability information of the user equipment in the CSR message and the CCR-I message, so that when the user equipment performs network attachment, the MME can carry the network capability information of the user equipment in the information element added in the CSR message and send it to the SAEGW. After receiving the network capability information sent by the MME, the SAEGW carries the network capability information in the information element added in the CCR-I message and sends it to the PCRF; that is, the method provided by the embodiment of the present invention improves the interface messages between the MME and the SAEGW, and between the SAEGW and the PCRF, and adds an information element for carrying the network capability information of the user in the interface message, so that the network capability information of the user equipment can be transmitted along with the interface message. Transmission, thereby realizing the transmission of the network capability of the user equipment to the PCRF; through the embodiment of the present invention, the PCRF can obtain the network capability information of the user equipment, so that the network capability of the user equipment can be identified based on the network capability information of the user equipment; by adopting the method provided by the embodiment of the present invention, there is no need to manually configure the network capability of the user equipment in the PCRF, and the PCRF can automatically obtain the network capability information, saving time and effort, and when the network capability information of the user equipment changes, the latest network capability information of the user equipment can be obtained in time, and the network capability of the user equipment can be adapted to the continuous changes, so that the PCRF can timely, accurately and efficiently identify the network capability of the user equipment, and timely grasp the changes and developments of the network capability of the user equipment.

[0080] Step 204, carry the above-mentioned network capability information in the information element added by the CSR message for carrying network capability information, and send it to SAEGW, so that SAEGW carries the network capability information in the information element added by the CCR-I message for carrying network capability information, and sends it to PCRF, so that PCRF identifies the network capability of the target user equipment according to the network capability information.

[0081] The above network capability information may include only the MS network capability information, or only the UE network capability information; or include both the MS network capability information and the UE network capability information.

[0082] Optionally, in a specific implementation, when the target user equipment is performing network attachment, the target user equipment sends a network attachment request to the MME, and the target user equipment carries its changed network capability information in the network attachment request and sends it to the MME; when the MME receives the network attachment request sent by the target user equipment, it obtains the network capability information of the target user equipment from the network attachment request, carries the network capability information in the information element added to the CSR message, and then carries it in the CSR message and sends it to the SAEGW; when the SAEGW receives the CSR message sent by the MME, it determines whether the CSR message carries the network capability information of the target user equipment, and if so, If the result indicates that the CSR message carries the network capability information of the target user equipment, the network capability information of the target user equipment is obtained from the CSR message, and the network capability information is carried in the information element added to the CCR-I message for carrying the network capability information, thereby carrying the network capability information of the target user equipment in the CCR-I message and sending it to the PCRF; when the PCRF receives the CCR-I message sent by the SAEGW, it obtains the network capability information of the target user equipment from the CCR-I message, parses the network capability information, and identifies the network capability of the user equipment based on the bit identifier of a byte in the parsed network capability information.
