[0073] In order to make the purpose, technical solutions and advantages of the present application clearer, the present application is further described in detail below in conjunction with the accompanying drawings and examples. It should be understood that the specific embodiments described herein are only used to explain the present application and are not intended to limit the present application.

The embodiments described in the following exemplary embodiments do not represent all embodiments consistent with the embodiments of the present application. They are only examples of devices and methods consistent with some aspects of the embodiments of the present application as detailed in the attached claims.

[0074] It is understood that the terms "first", "second", etc. used in this application can be used to describe various concepts in this article, but unless otherwise specified, these concepts are not limited by these terms. These terms are only used to distinguish one concept from another concept. For example, without departing from the scope of the embodiment of the present application, the first information may also be referred to as the second information, and similarly, the second information may also be referred to as the first information. Depending on the context, the words "if" and "if" as used herein can be interpreted as "at the time of" or "when" or "in response to determination".

[0075] The terms "at least one", "multiple", "each", "any", etc. used in this application, at least one includes one, two or more, multiple includes two or more, each refers to each of the corresponding multiple, and any refers to any one of the multiple.

[0076] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as those commonly understood by those skilled in the art to which this application belongs. The terms used herein are only for the purpose of describing the embodiments of this application and are not intended to limit this application.

[0077] Before describing the embodiments of the present application in detail, some nouns and terms involved in the embodiments of the present application are first described. The nouns and terms involved in the embodiments of the present application are subject to the following explanations.

[0078] 1) Access Point Name (APN) is a parameter that must be configured when a mobile phone accesses the Internet. It determines the access method used by the mobile phone to access the network, which directly affects the service that the user ultimately uses. For example, if a user needs to send MMS, the APN CTWAP needs to be set on the terminal so that the user's MMS proxy process can be used under the CTWAP access method; if the user needs to access Internet services, the APN of the terminal needs to be set to CTNET so that the user's Internet HTTP traffic can be used; if the user uses VoLTE voice services, the access point needs to be configured as IMS.

[0079] 2) Mobility Management Entity (MME): responsible for user access management, selecting the corresponding network element through the user APN, and creating service bearers.

[0080] 3) Home Subscriber Server (HSS): responsible for sending user APN subscription data.

[0081] With the development and growth of communication technology, users' personalized needs for service access are increasing. Not only must it be compatible with the mechanisms of various terminals and conform to the user's usage habits, but it must also meet the customized personalized needs of users in various scenarios and various services. In real business, when users access 4G and 5G services, the settings of the user terminal and the contract information in the user database must strictly correspond so that the process can be executed correctly and the service can be available. This inflexible approach cannot meet the business needs of the existing network.

[0082] In the related technology, during the process of establishing CTNET bearer for user data Internet access and IMS bearer for voice service, the core network needs to compare the APN access point reported by the terminal with the user's contracted information, and a strict correspondence is required for the service to proceed. The APN reported by the terminal depends on the user's manual configuration or the default built-in terminal. That is, the current service form is that the core network MME network element needs to perform a strong check on the APN reported by the terminal and the APN in the user's contracted database HSS. Only when they are completely matched can the corresponding bearer be created to realize data Internet access traffic in the CTNET bearer. However, this method requires a strong check on the APN reported by the terminal and the APN in the user's contracted database HSS, which is prone to the problem of exiting the service access process when a matching error occurs, resulting in the termination of the service access process and affecting the user experience.

[0083] In view of this, a service access processing method, device and electronic device are provided in the embodiments of the present application. The scheme obtains a judgment result by performing access point judgment processing on user contract information according to a network attachment request by a mobile management entity; when the judgment result is that the access points are inconsistent, error correction and backfill processing are performed on the user terminal, and the default access point is determined as the target access point; when the judgment result is that the access points are consistent, the reported access point is determined as the target access point; a bearer is established according to the target access point for service access, and access point error correction switching can be performed when the access points are inconsistent, thereby optimizing the service processing flow and improving the service processing efficiency.

[0084] A service access processing method provided in an embodiment of the present application relates to the field of wireless communication technology. A service access processing method provided in an embodiment of the present application can be applied to a terminal, can be applied to a server, or can be software running in a terminal or a server. In some embodiments, the terminal can be a smart phone, a tablet computer, a laptop computer, a desktop computer, a smart speaker, a smart watch, and a car terminal, etc., but is not limited to this; the server side can be configured as an independent physical server, or can be configured as a server cluster or distributed system composed of multiple physical servers, and can also be configured as a cloud server that provides basic cloud computing services such as cloud services, cloud databases, cloud computing, cloud functions, cloud storage, network services, cloud communications, middleware services, domain name services, security services, CDN, and big data and artificial intelligence platforms. The server can also be a node server in a blockchain network; the software can be an application that implements a service access processing method, etc., but is not limited to the above forms.

[0085] The present application can be used in many general or special computer system environments or configurations. For example: personal computers, server computers, handheld or portable devices, tablet devices, multiprocessor systems, microprocessor-based systems, set-top boxes, programmable consumer electronics, network PCs, minicomputers, mainframe computers, distributed computing environments including any of the above systems or devices, etc. The present application can be described in the general context of computer-executable instructions executed by a computer, such as program modules.

In a distributed computing environment, program modules can be located in local and remote computer storage media including storage devices.

[0086] It should be noted that in each specific implementation of the present application, when it comes to the need to perform relevant processing based on data related to user identity or characteristics such as user information, user behavior data, user historical data, and user location information, the user's permission or consent will be obtained first, and the collection, use, and processing of these data will comply with relevant laws, regulations, and standards. In addition, when the embodiment of the present application needs to obtain the user's sensitive personal information, the user's separate permission or consent will be obtained through a pop-up window or by jumping to a confirmation page. After clearly obtaining the user's separate permission or consent, the necessary user-related data for the normal operation of the embodiment of the present application will be obtained.

[0087] Figure 1 is an optional flowchart of a service access processing method provided in an embodiment of the present application. Figure 1 The method may include but is not limited to steps S101 to S106.

[0088] Step S101, receiving a network attachment request initiated by a user terminal, wherein the network attachment request includes reporting an access point;

[0089] Step S102, performing contract information acquisition processing on the user contract data server to obtain user contract information, wherein the user contract information includes a default access point;

[0090] Step S103, performing access point determination processing on the user subscription information according to the network attachment request to obtain a determination result;

[0091] Step S104, when the judgment result is that the access points are inconsistent, error correction and backfill processing are performed on the user terminal, and the default access point is determined as the target access point;

[0092] Step S105, when the judgment result is that the access points are consistent, determining the reported access point as the target access point;

[0093] Step S106: establishing a bearer according to the target access point to access the service.

[0094] Steps S101 to S106 shown in the embodiment of the present application enable the access point error correction function in the mobile management entity, so that the problem access point can be corrected in the service form of multiple access points with multiple bearers, without affecting the normal access point, and maintaining the original service process. Specifically, the mobile management entity receives a network attachment request initiated by the user terminal, wherein the network attachment request includes a reported access point. And the user contract data server is processed for contract information acquisition, and the user contract information can be obtained from the user contract data server through the S6a interface, wherein the S6a interface is an interface between the mobile management entity and the user contract data server in the network, and the user contract information includes at least one contract access point, and the contract access point includes a default access point. According to the network attachment request, the user contract information is processed for access point judgment, that is, the reported access point in the network attachment request is matched with the contract access point in the user contract information to obtain a judgment result. When the user contract information does not include the reported access point, that is, the judgment result is that the access point is inconsistent, the user terminal is corrected and backfilled, and the default access point is determined as the target access point. When the user contract information includes a reported access point, the judgment result is that the access points are consistent, and the reported access point is determined as the target access point. After obtaining the target access point, the corresponding service bearer is established to access the service.

[0095] In some embodiments, performing error correction and backfill processing on the user terminal and determining the default access point as the target access point includes the following steps:

[0096] Performing access point modification processing on the user terminal, and ending service access processing when the user terminal refuses modification;

[0097] When the user terminal receives the modification, the reported access point is modified to be the default access point and is filled back into the network attachment request, and the default access point is determined as the target access point.

[0098] In an embodiment of the present application, when the mobile management entity of the core network turns on the access point error correction function, if some special terminals in the existing network, such as Apple terminals and industrial customized terminals, cannot modify the access point on the terminal side or some users are unwilling to modify the access point, it will cause access rejection and directly end the service access processing. If the user terminal receives the modification, the reported access point in the network attachment request is modified to the default access point in the user contract information and filled back into the network attachment request. The modified network attachment request will be returned to the user terminal. The backfill processing can enable the user terminal to identify the access point that needs to be modified to perform access point error correction processing. The mobile management entity determines the default access point as the target access point, and then establishes the corresponding service bearer according to the target access point, so that the user terminal can access the corresponding service.

[0099] One of the above technical solutions has the following advantages or beneficial effects: the embodiment of the present application can modify the access point by modifying the access point, and can modify it according to the default access point when the user terminal reports an erroneous access point, maintain the service access process for corresponding service access, and improve the service access processing efficiency.

[0100] In some embodiments, establishing a bearer according to the target access point to access the service includes the following steps:

[0101] Find and obtain a serving gateway and a packet gateway according to the target access point;

[0102] Instruct the serving gateway and the packet gateway to establish a bearer for service access.

[0103] In the embodiment of the present application, the mobile management entity obtains the target access point to find the corresponding service gateway SGW and packet gateway PGW, and instructs the service gateway and packet gateway to establish the corresponding service bearer, so that the user can perform the corresponding service. Specifically, the mobile management entity constructs the domain name of the service gateway and the packet gateway according to the tracking area code where the user is located, and then queries the corresponding gateway according to the constructed domain name, and sorts according to the priority and weight of the gateway host, so as to select the corresponding service gateway and packet gateway.

[0104] One of the above technical solutions has the following advantages or beneficial effects: the embodiment of the present application establishes a bearer for service access according to the target access point, and can select the corresponding service gateway and packet gateway to establish a service bearer for corresponding service access according to the finally determined target access point, thereby improving the service access processing efficiency.

[0105] In some embodiments, the step of finding a serving gateway and a packet gateway according to the target access point comprises the following steps:

[0106] Performing gateway information matching processing on the user contract information according to the target access point to obtain a contract gateway host name;

[0107] The service gateway and the packet gateway are obtained by searching according to the host name of the contracted gateway.

[0108] In an embodiment of the present application, the mobile management entity can match the user contract information with the gateway information according to the target access point. At this time, the contract gateway host name needs to be pre-stored in the user contract information. By directly signing the host name or IP address of the gateway on the user contract data server, the corresponding service gateway and packet gateway can be directly matched and found. In international usage scenarios, the mobile management entity searches for the packet gateway by recursively querying the network element host name and IP address through the DNS network element, which requires cross-border DNS resolution and has certain limitations in business. However, by directly signing the host name or IP address of the gateway on the user contract data server, the gateway can be quickly found.

[0109] One of the above technical solutions has the following advantages or beneficial effects: the embodiment of the present application quickly matches the corresponding gateway by pre-signing a gateway host on the user contract data server, thereby effectively improving the configuration efficiency.

[0110] See also Figure 2 Another aspect of the embodiment of the present application provides a service access processing method, which is applied to a user subscription data server and includes the following steps:

[0111] Step S201, setting a roaming template according to a roaming scenario;

[0112] Step S202, receiving a subscription data acquisition request initiated by a mobility management entity;

[0113] Step S203, performing a policy determination process on the roaming template according to the subscription data acquisition request to obtain user subscription data;

[0114] Step S204: Send the user subscription data to the mobility management entity.

[0115] In an embodiment of the present application, a corresponding roaming template may be set on a user contract data server according to different roaming scenarios, and the roaming template includes a public land mobile network value and a user contract access point, wherein the user contract access point includes a default access point. By receiving a contract data acquisition request initiated by a mobile management entity, the user contract data server identifies the roaming scenario of the mobile management entity, and may identify the corresponding roaming scenario according to the public land mobile network value, such as identifying a domestic roaming scenario or an international roaming scenario. Then, according to the identified roaming scenario, a corresponding delivery strategy is matched from the roaming template, such as establishing a domestic roaming template and an international roaming template in the roaming template. When the roaming scenario of the mobile management entity is identified through the contract data acquisition request, a user contract access point is selected from the matched corresponding roaming template as the user contract data, and the user contract data is sent to the mobile management entity.

[0116] One of the above technical solutions has the following advantages or beneficial effects: By establishing a roaming template, the embodiment of the present application can match the policy for different roaming scenarios, thereby realizing the personalized needs of users and optimizing access points in different usage locations or roaming areas.

[0117] In some embodiments, setting the roaming template according to the roaming scenario specifically includes the following steps:

[0118] determining a public land mobile network value according to the roaming scenario;

[0119] Obtaining a user subscription access point according to the public land mobile network value configuration;

[0120] The public land mobile network value and the user subscription access point are set as the roaming template.

[0121] In the embodiment of the present application, different public land mobile network values ​​can be obtained according to different roaming scenarios. For example, the public land mobile network value can be set to 46011 for domestic roaming scenarios, and can be set to 46055 for international roaming scenarios. Therefore, different roaming scenarios can be obtained by identifying the public land mobile network value. And the user subscription access point is configured according to the public land mobile network value, and the corresponding user subscription access point can be configured according to actual needs, such as configuring the user subscription access point to include CMNET and IMS. Finally, the public land mobile network value and the user subscription access point are set as a roaming template, and multiple roaming templates can be set according to different land mobile network values ​​and user subscription access points.

[0122] One of the above technical solutions has the following advantages or beneficial effects: By setting the public land mobile network value and the user contract access point setting in the roaming template, the embodiment of the present application can identify the roaming scenario according to the public land mobile network value and configure the corresponding user contract access point, thereby improving the service access processing efficiency.

[0123] In some embodiments, the step of obtaining a user subscription access point according to the public land mobile network value configuration includes the following steps:

[0124] Determining a preset subscription access point according to the public land mobile network value;

[0125] A default access point is selected from the preset contract access points to perform gateway information binding processing to obtain the user contract access point.

[0126] In the embodiment of the present application, the preset contract access point can be determined according to the public land mobile network value, and different preset contract access points are set for different public land mobile network values. For example, when the public land mobile network value is 46011, the preset contract access point is set to CMNET and I MS; when the public land mobile network value is 46055, the preset contract access point is set to CTNET and I MS. Then, an access point is selected from the preset contract access points as the default access point, and the default access point is bound to the gateway information to obtain the user contract access point. The embodiment of the present application adds a bound gateway IP address to the default access point to facilitate fast matching of the gateway. Among them, the user contract access point includes the preset contract access point, and the preset contract access point includes a default access point.

[0127] One of the above technical solutions has the following advantages or beneficial effects: the embodiment of the present application selects one of the user's contracted access points as the default access point, and when an access point matching error occurs, the default access point can be used as the target access point to continue service access processing, thereby improving service processing efficiency.

[0128] The following is a detailed description of the embodiments of the present invention with reference to specific application examples:

[0129] See also Figure 3 In the embodiment of the present application, the network attachment is initiated by the user terminal, and the mobile management entity MME obtains the user contract information from the HSS through the S6a interface (the contract information only includes CTNET and is the default APN). The MME asks the user terminal to report the required APN (for example, CMNET). The MME determines that the user APN is inconsistent, enables error correction and backfill measures, and corrects the access point to CTNET. The MME instructs the SGW and PGW to establish a default bearer with the access point as CTNET, and the user can access the Internet.

[0130] See also Figure 4 , the user terminal initiates network attachment. MME obtains the user contract information from HSS through the S6a interface (the contract information includes CTNET and is the default APN, and there is I MS but it is a non-default APN). MME asks the user terminal to report the required APN (for example, CMNET). MME determines that the user APN is inconsistent, enables error correction and backfill measures, and corrects the error to CTNET. MME instructs SGW and PGW to establish the default bearer for CTNET, and the user can access the Internet. The user terminal initiates PDN connection establishment and carries the APN service access point (I MS). MME determines that the user APN is consistent with the contract, does not perform error correction, and uses the old process and I MS. MME instructs SGW and PGW to establish the default bearer for I MS, and the user can use voice services.

[0131] See also Figure 5 , the user terminal initiates network attachment. The domestic MME (PLMN is 46011) obtains the user contract information from the HSS through the S6a interface (the contract information is: under PLMN46011, CMNET is the default APN and I MS is the non-default APN; under PLMN46055, CTNET is the default APN and I MS is the non-default APN; therefore, HSS sends CMNET as the default APN and I MS as the non-default APN). The MME asks the user terminal to report the required APN (for example, CMNET). The MME determines that the user APN is consistent with the contract, does not enable error correction and backfill measures, and remains CMNET. The MME instructs the SGW and PGW to establish the default bearer of CMNET, and the user can surf the Internet. The user terminal initiates PDN connection establishment and carries the APN service access point (I MS). The MME determines that the user APN is consistent with the contract, does not perform error correction, and uses the old process and I MS. The MME instructs the SGW and PGW to establish the default bearer of I MS, and the user can use voice services.

[0132] See also Figure 6 , the user terminal initiates network attachment. The foreign MME (PLMN is 46055) obtains the user contract information from the HSS through the S6a interface (the contract information is as follows: under PLMN46011, CMNET is the default APN and I MS is the non-default APN; under PLMN46055, CTNET is the default APN and I MS is the non-default APN; therefore, HSS sends CTNET as the default APN and carries the IP address of PGW, and I MS is the non-default APN). MME asks the user terminal to report the required APN (such as CMNET). MME determines that the user APN is inconsistent with the contract, enables error correction and backfill measures, and uses CTNET. MME instructs SGW and PGW (without DNS recursive query, directly obtain the HSS contracted PGW host name) to establish the default bearer of CTNET, and the user can surf the Internet. The user terminal initiates PDN connection establishment and carries the APN service access point (I MS). MME determines that the user APN is consistent with the contract, does not perform error correction, and uses the old process and I MS. MME instructs SGW and PGW to establish the default bearer of IMS, and users can perform voice services. In this networking mode, the embodiment of the present application can continue to optimize the service expansion configuration of the APN user access point on PGW, deploy black and white lists, VXLAN / GRE and other tunnel technologies on PGW, and support the deployment of AAA authentication, which greatly broadens the role of APN access point optimization work and is strongly related to business development.

[0133] See also Figure 7First, in the test scenario, a user roaming template is created for HSS. For the first roaming scenario, the user's subscribed APN is set to CTNET and I MS, where CTNET is the default APN and I MS is the non-default APN. The judgment condition is that the PLMN of the user accessing MME is 46011; for the second roaming scenario, the user's subscribed APN is set to aqpb.gd.iot and I MS, where aqpb.gd.iot is the default APN and I MS is the non-default APN. The judgment condition is that the PLMN of the user accessing MME is 45507. At the same time, the user's aqpb.gd.iot APN is bound to the PGW IP address 183.18.31.21, and the number is subscribed to the roaming template.

[0134] Secondly, configure the APN (aqpb.gd.iot) on the PGW (IP is 183.18.31.21) and connect it to the platform server to open up the application path to the platform. When the user number is used in the first scenario (PLMN is 46011), the specific process is consistent with the common service. When the user number roams to the second scenario (PLMN is 45507), the specific implementation is as follows:

[0135] In the first step, the user terminal initiates network attachment.

[0136] In the second step, the MME in the second scenario (PLMN is 45507) obtains the user contract information from the HSS through the S6a interface (the contract information is as follows: under PLMN46011, CTNET is the default APN and I MS is the non-default APN; under PLMN45507, aqpb.gd.iot is the default APN and I MS is the non-default APN; therefore, the HSS sends aqpb.gd.iot as the default APN and carries the IP address 183.18.31.21 of the PGW, and I MS is the non-default APN).

[0137] In the third step, MME asks the user terminal to report the required APN (the user switches seamlessly, so the terminal reports CTNET used in domestic scenarios).

[0138] In the fourth step, MME determines that the user's APN is inconsistent with the contract, enables error correction and backfill measures, and uses aqpb.gd.iot.

[0139] In the fifth step, MME instructs SGW and PGW (without DNS recursive query, directly obtain HSS contracted PGW IP 183.18.31.21) to establish the default bearer of aqpb.gd.iot. Users can access the Internet and communicate with the customer intranet and access customer intranet applications.

[0140] In the sixth step, the user terminal initiates the establishment of a PDN connection and carries the APN service access point (IMS).

[0141] In the seventh step, MME determines that the user APN is consistent with the contract, does not perform error correction, and continues to use the old process and I MS.

[0142] In step 8, the MME instructs the SGW and PGW to establish the default bearer of the IMS so that the user can perform voice services.

[0143] During the test, users can switch APN seamlessly without setting up additional APN access points. In the second roaming area, both aqpb.gd.i ot and I MS bearers can be established. aqpb.gd.i ot directly accesses the user's enterprise intranet to access intranet applications. VoLTE registration is successful, and calling and called parties are normal, achieving service access.
