The technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present application. Obviously, the described embodiments are part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without creative work fall within the protection scope of the present application.

In addition, "and/or" in the description and claims indicates at least one of the connected objects, and the character "/" generally indicates that the associated objects are in an "or" relationship.

The network access method provided by the embodiment of the present application can be applied to at least the following application scenarios, which are described below.

At present, electronic devices with multiple card slots can install multiple SIM cards, allowing users to have one electronic device and experience the services of different operators, but also bring challenges to some businesses.

Among them, a Wi-Fi-based voice service (Voice over Wi-Fi, VoWiFi) service is a relatively common service of electronic equipment. VoWiFi has five different network architectures, and is currently widely used. The networking solution favored by most electronic equipment manufacturers is the S2b interface networking solution, also known as the untrusted domain core network (EPC) access solution.

Among them, in the untrusted domain EPC access scheme, all Wi-Fi (WIreless-Fidelity, Wireless Fidelity) hotspots and other untrusted domain devices can be accessed, and accessed through the Evolevd Packet Data Gateway (ePDG) PDN gateway (PDN Gateway, PGW), realizes the intercommunication with EPC. Since the untrusted domain access network and the EPC use the S2b interface for intercommunication, this networking is also called the S2b interface networking solution. This solution does not require modification of the Wireless Local Area Network (WLAN), has high security, supports seamless handover, and solves the problem of continuity of voice and data services.

This solution makes good use of the existing wireless network, and only needs a simple transformation on the basis of the original network to realize the function of VoWiFi, so it is strongly supported by operators and electronic equipment manufacturers. In this solution, the electronic device accesses the operator's trusted mobile network through an untrusted wireless network, and uses the PGW as an anchor point for handover between WLAN and Long Term Evolution (Long Term Evolution, LTE). Among them, the PGW is an important network element in the mobile communication network EPC. The PGW is the border gateway of the EPC network and provides functions such as user session management and bearer control, data forwarding, and network protocol address allocation.

Based on the above S2b interface networking solution, after a series of authentication and authentication, services such as voice, video, and short messages can be implemented. The development of VoWiFi service only needs to add ePDG and authentication, authorization and accounting (Authentication Authorization and Accounting, 3GPP AAA) network elements, in which ePDG can be regarded as a connection support network element between VoWiFi network and PGW. It connects to the termination SWu interface of the untrusted WiFi network, interacts with the electronic device through the Internet Key Exchange Protocol (IKEv2) message, obtains the authentication information of the electronic device, and then interacts with the 3GPP AAA to complete the user authentication. and certification. Decapsulate the user data transmitted by the electronic device through the Internet Protocol Security (IPSec) tunnel, and transmit the re-encapsulated user data through the GTP tunnel between itself and the PGW.

Therefore, ePDG plays a pivotal role connecting untrusted WiFi networks and PGW network elements. The choice of ePDG has a great impact on the development of VoWiFi services.

For an electronic device including multiple SIM cards, it is assumed that the probability that each SIM card can successfully conduct business is a, b, ···, n, where n is a positive integer. The value range of each probability is in [0,1]. When there is only one SIM card, the probability of successfully performing the VoWiFi service is a; when there are two cards, the probability of successfully performing the VoWiFi service is between [a, ab], and so on. The more the number of SIM cards, the lower the probability of successful VoWiFi business.

Aiming at the problems in the related art, the embodiments of the present application provide a network access method and device, so as to solve the problem of low access efficiency of the VoWiFi service in the related art with the increase of SIM cards.

The method provided by the embodiment of the present application can be applied to any scenario where the access efficiency of the VoWiFi service is low as the number of SIM cards increases, in addition to the above application scenarios.

Through the method provided by the embodiment of the present application, the second SIM card is controlled to initiate an authentication request through the target ePDG address by obtaining the target ePDG address that the first SIM card registers for the wireless fidelity-based voice service VoWiFi and passes the authentication. Since the target ePDG address is the gateway address through which the authentication request initiated by the first SIM card passes, the probability of passing the authentication request initiated by the second SIM card to the target ePDG address is greatly increased, which can reduce the time for interaction with the network and improve access to VoWiFi. business efficiency.

Based on the above application scenario, the following briefly describes the network access method provided by the embodiment of the present application with reference to the architecture diagram shown in FIG. 1 .

First, for any SIM card in the electronic device 100, it is possible to connect to the ePDG 300 through any WiFi wireless access point (ie, the network 200). Then, the ePDG300 is connected to the PGW400. Finally, the IMS core network 500 is accessed through the PGW 400 . Since the electronic device 100 and the ePDG 300 are in a public network and there are insecure factors, an IPSec secure tunnel will be established between the electronic device 100 and the ePDG 300, and the electronic device 100 can complete the identity authentication and IPSec establishment process through the IKEv2 protocol. After the IPSec is established, the VoWiFi service can be registered with the IMS core network and subsequent service calls can be made. Based on the solution shown in FIG. 1 above, all Wi-Fi hotspots and other untrusted domain devices can be accessed, and the PGW can be accessed through the ePDG to realize intercommunication with the core network. This solution does not require modification of WLAN, has high security, and ensures the continuity of voice and data services.

For the electronic device, in response to the access request of each SIM card to the wireless fidelity-based voice service VoWiFi, the ePDG address is queried, and then each SIM card is controlled to initiate an authentication request to the corresponding ePDG address; in the first When the authentication request initiated by the SIM card passes and the authentication request initiated by the second SIM card fails, the second SIM card is controlled to initiate an authentication request to the target ePDG address that has passed the authentication request. Since the speed of obtaining the target ePDG address passed by the authentication request is much faster than the speed of re-querying the ePDG address, the probability of passing the authentication request initiated by the second SIM card to the target ePDG address is greatly increased, thereby reducing the time for interacting with the network. , to improve the efficiency of accessing VoWiFi services.

Based on the above application scenario, the network access method provided by the embodiment of the present application is described in detail below.

FIG. 2 is a flowchart of a network access method provided by an embodiment of the present application.

As shown in FIG. 2 , the network access method may include steps 210 to 220, and the method is applied to a network access device, as follows:

In step 210, a target ePDG address is obtained, and the target ePDG address is the ePDG address registered by the first SIM card for VoWiFi and passed the authentication.

Step 220, controlling the second SIM card to initiate an authentication request through the target ePDG address.

The network access method provided by the present application controls the second SIM card to initiate an authentication request through the target ePDG address by obtaining the target ePDG address registered by the first SIM card for the wireless fidelity-based voice service VoWiFi and passing the authentication. Since the target ePDG address is the gateway address through which the authentication request initiated by the first SIM card passes, the probability of passing the authentication request initiated by the second SIM card to the target ePDG address is greatly increased, which can reduce the time for interaction with the network and improve access to VoWiFi. business efficiency.

The following is a brief introduction to the professional terms involved in this application.

A SIM card is a subscriber identification card held by mobile users of the Global System for Mobile Communications (GSM). The GSM system identifies GSM users through the SIM card. The same SIM card can be used on different electronic devices. Electronic devices can only be used after inserting a SIM card. The SIM card is the key for the electronic device to connect to the GSM network. After the SIM card is installed in the electronic device, it can enjoy various services provided by the network operator.

VoWiFi technology came into being. This technology uses the existing Wi-Fi (WIreless-Fidelity, wireless fidelity) network to realize wireless VoIP voice calls. Users can make roaming voice calls at any time within the coverage of WLAN network through VoWiFi electronic devices. ,video call. VoWiFi uses WiFi as an access network, and ultimately accesses IMS (IP Multimedia Subsystem, IP Multimedia Subsystem), which is an IP voice service that operators can control and manage. VoWiFi technology has attracted more and more attention due to its low communication cost and the convenience brought by WLAN for users.

Below, the contents of steps 210 to 220 are described respectively:

First, step 210 is involved.

In a possible embodiment, before step 210, the following steps may also be included:

Obtain the authentication result that each SIM card initiates an authentication request to the ePDG address;

Determine the first SIM card and the second SIM card according to the authentication result; the authentication result of the first SIM card is that the authentication request has passed, and the authentication result of the second SIM card is that the authentication request has failed;

Determine the target ePDG address corresponding to the first SIM card.

After all SIM cards have completed the first round of the ePDG authentication process, the electronic device can know which ePDGs authenticated by the SIM cards are available according to the authentication result. That is, it is determined that the authentication result is the target ePDG address corresponding to the first SIM card that has passed the authentication request. The first SIM card that passes the authentication request may register for VoWiFi through the target ePDG address.

Wherein, before the above-mentioned steps involved in obtaining the authentication result that each SIM card initiates an authentication request to the ePDG address, the following steps may also be included:

In response to the access request of each SIM card to VoWiFi, query the ePDG address to obtain the address query result; control each SIM card to initiate an authentication request to the ePDG address corresponding to the address query result.

Multiple SIM cards of the electronic device respectively initiate VoWiFi services, and query ePDG information through the static query method configured locally or through the dynamic query method of the Domain Name System (DNS) to obtain the address query result. After the address query result is obtained, each SIM card can be controlled to initiate an authentication request to the ePDG address corresponding to the address query result.

In a possible embodiment, when the authentication requests initiated by multiple SIM cards fail, the ePDG address is queried to determine the updated ePDG address; multiple SIM cards are controlled to initiate authentication requests to the updated ePDG address.

If the authentication requests initiated by multiple SIM cards fail, the ePDG information can be queried again through the static query method configured locally or the dynamic query method through DNS to determine the updated ePDG address. Then control multiple SIM cards to initiate an authentication request to the updated ePDG address.

Next, step 220 is involved.

Since the ePDG is invalid and the second SIM card of VoWiFi cannot be registered, the target ePDG address of the first SIM card successfully registered with VoWiFi can be tried preferentially, and a suitable ePDG can be selected to try. Since the target ePDG address is previously authenticated by the first SIM card, when the second SIM card initiates an authentication request to the target ePDG address, the probability that the authentication result is an authentication pass is greatly increased.

That is to say, through the above-mentioned multi-card prior method, it is assumed that the probability that each SIM card can successfully conduct business is a, b, ···, n, where n is a positive integer. The value range of each probability is [0, 1]. When there is only one SIM card, the probability of failing to conduct VoWiFi services is 1-a; when there are two cards, the probability of failing to conduct VoWiFi services is [(1-a)(1-b), 1- a], and so on, only one card is needed for VoWiFi to work normally, and other cards are considered to be able to work normally. At this time, the failure probability of VoWiFi service is (1-a)(1-b)...(1-n). The more cards there are, the lower the failure probability is. This makes full use of the advantages of multiple cards and can improve the Probability of successful VoWiFi service development in the case of multiple SIM cards.

Wherein, in step 220, the following steps may be specifically included:

Determine the first operator to which the first SIM card belongs, and the second operator to which the second SIM card belongs; if the first operator and the second operator are consistent, or, if the first operator and the second operator Under the condition that the business complies with the preset contract conditions, the second SIM card is controlled to initiate an authentication request to the target ePDG address.

Wherein, as shown in FIG. 3, in step 220, the following steps may be specifically included:

Step 310: Determine the first operator to which the first SIM card belongs, and the second operator to which the second SIM card belongs.

Step 320, in the case that the first operator is consistent with the second operator, control the second SIM card to initiate an authentication request to the target ePDG address.

That is, when the first SIM card and the second SIM card belong to the same operator, the second SIM card can be controlled to initiate an authentication request to the target ePDG address.

In addition, as shown in FIG. 4 , in step 220, the following steps may be specifically included:

Step 410: Determine the first operator to which the first SIM card belongs, and the second operator to which the second SIM card belongs.

Step 420, in the case that the first operator and the second operator meet the preset contract conditions, control the second SIM card to initiate an authentication request to the target ePDG address.

That is, when the operators to which the first SIM card and the second SIM card belong are operators that have signed a contract and mutually recognize each other, the second SIM card can be controlled to initiate an authentication request to the target ePDG address.

Therefore, in the case that the electronic device includes multiple SIM cards, as long as one SIM card (the first SIM card) is successfully registered with VoWiFi, and the first operator is the same as the second operator, or in the first SIM card Under the condition that the first operator and the second operator meet the preset contract conditions, other SIM cards (second SIM cards) can learn from the target ePDG address of the first SIM card to initiate VoWiFi registration. Since the electronic device knows the target ePDG address selected by all SIM cards that have successfully registered with VoWiFi, the second SIM card cannot be registered for VoWiFi due to the unavailability of the ePDG address. This can greatly improve the success rate and efficiency of VoWiFi access, thereby improving the user experience.

In another possible embodiment, after step 220, the following steps may also be included:

In the case where the second SIM card fails to initiate the authentication request to the target ePDG address, the ePDG address of the second SIM card is re-queried in the authentication result, and the updated ePDG address of the second SIM card is determined, and the updated ePDG address is the authentication In the result, the ePDG address other than the target ePDG address passed the authentication request; the second SIM card is controlled to initiate an authentication request to the updated ePDG address.

In the electronic device, the second SIM card that cannot be registered on VoWiFi due to invalid ePDG can first try the target ePDG address. If the second SIM card fails to initiate an authentication request to the target ePDG address, the ePDG address of the second SIM card can be re-queried. In the authentication result, the ePDG addresses that pass the authentication request except the target ePDG address are determined, that is, the updated ePDG address of the second SIM card. Then, the second SIM card is controlled to initiate an authentication request to the updated ePDG address.

In addition, if the second SIM card fails to initiate an authentication request to the updated ePDG address, the ePDG address can be queried by the original static query or dynamic DNS query again to determine the updated ePDG address, and then control the second SIM card to send The updated ePDG address initiates an authentication request.

To sum up, in the embodiment of the present application, the target ePDG address that the first SIM card registers for the wireless fidelity-based voice service VoWiFi and passes the authentication is obtained, and then the second SIM card is controlled to initiate an authentication request through the target ePDG address. Since the target ePDG address is the gateway address through which the authentication request initiated by the first SIM card passes, the probability of passing the authentication request initiated by the second SIM card to the target ePDG address is greatly increased, which can reduce the time for interaction with the network and improve access to VoWiFi. business efficiency.
