All other embodiments, which can be made by one of ordinary skill in the art based on the embodiments herein without making any inventive effort, are intended to be within the scope of the present application.

It is to be understood that the data so used may be interchanged where appropriate such that embodiments of the present application may be implemented in sequences other than those illustrated or described herein. Furthermore, in the description and claims, "and/or" means at least one of the connected objects, and the character "/", generally means that the associated object is an "or" relationship.
The network access method provided by the embodiment of the application can be at least applied to the following application scenarios, and the following description is provided.
At present, a plurality of SIM cards can be installed on the multi-card slot electronic equipment, so that a user can experience different operator services while having one electronic equipment, and challenges are brought to some businesses.
Among them, wi-Fi (Voice over Wi-Fi) service is a relatively common service for electronic devices. VoWiFi has five different network architectures, and is widely used at present, and a networking scheme favored by most electronic equipment manufacturers is an S2b interface networking scheme, which is also called an untrusted domain core network (EPC) access scheme.
The non-trust domain EPC access scheme is that all non-trust domain devices such as Wi-Fi (WIreless Fidelity) hot spots can be accessed, and an evolved packet data Gateway (Evolevd Packet Data Gateway, ePDG) is accessed to a PDN Gateway (PDN Gateway, PGW) to realize interworking with EPC. Since the untrusted domain access network and EPC interworking employ an S2b interface, this networking is also referred to as an S2b interface networking scheme. The proposal has no reconstruction requirement on WLAN, has high safety, supports seamless switching and solves the problem of continuity of voice and data services.
The scheme well utilizes the existing wireless network, and can realize the function of VoWiFi by simple modification on the basis of the original network, so that the scheme is strongly supported by operators and electronic equipment manufacturers. In this scheme, the electronic device accesses to a mobile network trusted by an operator through an untrusted wireless network, and uses PGW as an anchor point for wireless local area network (Wireless Local Area Network, WLAN) and long term evolution (Long Term Evolution, LTE) handover. Wherein PGW is an important network element in the EPC of a mobile communication network. The PGW is a border gateway of the EPC network, and provides functions such as session management and bearer control, data forwarding, and network protocol address allocation for the user.
Based on the S2b interface networking scheme, after a series of authentications and authentications, services such as voice, video, short messages and the like can be realized. The deployment of VoWiFi services requires only the addition of ePDG and authentication, authorization and accounting (Authentication Authorization and Accounting,3GPP AAA) network elements, where ePDG can be regarded as one connection support network element between VoWiFi network and PGW. The method is connected with a terminating SWu interface of a non-trusted WiFi network, interacts with the electronic equipment through an Internet key exchange protocol (IKEv 2) message to acquire authentication information of the electronic equipment, and then interacts the authentication information with a 3GPP AAA, so that user authentication and authentication are completed. The user data tunneled by the electronic device through internet security protocol (Internet Protocol Security, IPSec) is decapsulated, and the repackaged user data is tunneled through a GTP tunnel between itself and the PGW.
Thus, ePDG acts as a hub connecting the untrusted WiFi network and the PGW network element. The selection of ePDG has a great impact on the development of VoWiFi services.
For electronic devices that include multiple SIM cards, the probability that each SIM card can successfully develop the service is assumed to be a, b, & gtand n, and n is a positive integer. The value range of each probability is 0, 1. When only one SIM card is used, the probability of being able to successfully perform VoWiFi service is a; when two cards exist, the probability of being able to successfully perform the VoWiFi service is between [ a, ab ], and so on, and as the number of SIM cards in the electronic equipment is larger, the probability of being able to successfully perform the VoWiFi service is lower.
Aiming at the problems of the related art, the embodiment of the application provides a network access method and device, so as to solve the problem of low VoWiFi service access efficiency along with the increase of SIM cards in the related art.
The method provided by the embodiment of the application can be applied to not only the application scenes, but also any scenes with low VoWiFi service access efficiency along with the increase of the SIM card.
According to the method provided by the embodiment of the application, the target ePDG address which is based on the voice service VoWiFi and passes authentication is registered by acquiring the first SIM card, and then the second SIM card is controlled to initiate an authentication request by the target ePDG address. Because 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 improved, so that the time of interaction with a network can be reduced, and the efficiency of accessing VoWiFi service is improved.
Based on the above application scenario, the network access method provided in the embodiment of the present application is briefly described below 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 ePDG300 through any one WiFi wireless access point (i.e., network 200). Then, the ePDG300 connects to the PGW400; finally, the IMS core network 500 is accessed through the PGW 400. Since a public network exists between the electronic device 100 and the ePDG300, an IPSec secure tunnel is established between the electronic device 100 and the ePDG300, and the electronic device 100 can complete the identity authentication and IPSec establishment procedures through IKEv2 protocol. After IPSec establishment is completed, voWiFi service can be registered with the IMS core network and subsequent service calls can be made. Based on the scheme shown in fig. 1, all non-trust domain devices such as Wi-Fi hotspots can be accessed, and PGW is accessed through ePDG to realize intercommunication with the core network. The scheme has no reconstruction requirement on WLAN, has high safety, and ensures the continuity of voice and data services.
For the electronic equipment, responding to an access request of each SIM card to the voice service VoWiFi based on wireless fidelity, inquiring an ePDG address, and then controlling each SIM card to initiate an authentication request to the corresponding ePDG address; and under the condition that the authentication request initiated by the first SIM card passes and the authentication request initiated by the second SIM card fails, controlling the second SIM card to initiate the authentication request to the target ePDG address through which the authentication request passes. The speed of acquiring the target ePDG address through which the authentication request passes is far faster than the speed of re-inquiring the ePDG address, so that the probability of the second SIM card for initiating the authentication request to the target ePDG address to pass is greatly improved, the time of interaction with a network can be further reduced, and the efficiency of accessing the VoWiFi service is improved.
Based on the above application scenario, the network access method provided in the embodiment of the present application is described in detail below.
Fig. 2 is a flowchart of a network access method provided in an embodiment of the present application.
As shown in fig. 2, the network access method may include steps 210-220, where the method is applied to a network access device, as follows:
step 210, obtaining a target ePDG address, where the target ePDG address is an ePDG address that registers VoWiFi for the first SIM card and passes authentication.
Step 220, the second SIM card is controlled to initiate an authentication request by the target ePDG address.
According to the network access method, the target ePDG address which is based on the voice service VoWiFi and passes authentication is registered through the first SIM card, and then the second SIM card is controlled to initiate an authentication request by the target ePDG address. Because 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 improved, so that the time of interaction with a network can be reduced, and the efficiency of accessing VoWiFi service is improved.
The following presents a simplified summary of the specialized terms involved in this application.
The SIM card is a subscriber identity card held by a mobile subscriber of the global system for mobile communications (Global System for Mobile Communications, GSM) system. The GSM system identifies the GSM user through the SIM card. The same SIM card can be used on different electronic devices. The electronic device can access the network for use only after the SIM card is inserted. The SIM card is a key for connecting the electronic device to the GSM network, and after the SIM card is installed in the electronic device, the electronic device can enjoy various services provided by the network operator.
VoWiFi technology has been developed, which uses existing Wi-Fi (WIreless Fidelity) networks to implement WIreless VoIP voice calls, and users can perform roaming voice and video calls at any time within the coverage area of the WLAN network through VoWiFi electronic devices. VoWiFi uses WiFi as an access network, and finally to access IMS (IP Multimedia Subsystem ), which is a voice over IP service that can be controlled and managed by an operator. VoWiFi technology is receiving more and more attention because of its low communication cost and convenience brought by users to obtain WLAN.
The contents of steps 210 to 220 are described below:
first, step 210 is referred to.
In one possible embodiment, before step 210, the following steps may be further included:
acquiring an authentication result of each SIM card initiating an authentication request to an ePDG address;
determining a first SIM card and a second SIM card according to the authentication result; the authentication result of the first SIM card is that the authentication request passes, and the authentication result of the second SIM card is that the authentication request fails;
and determining a target ePDG address corresponding to the first SIM card.
After all the SIM cards complete the first round of ePDG authentication procedure, the electronic device can learn which epdgs authenticated by the SIM cards are available according to the authentication result. The authentication result can be determined to be the target ePDG address corresponding to the first SIM card through which the authentication request passes. The first SIM card through which the authentication request passes can register VoWiFi through the target ePDG address.
Before the step of acquiring the authentication result of each SIM card initiating the authentication request to the ePDG address, the method may further include the following steps:
responding to the access request of each SIM card to VoWiFi, inquiring the ePDG address, and obtaining an address inquiry result; and controlling each SIM card to initiate an authentication request to the ePDG address corresponding to the address inquiry result.
And respectively initiating VoWiFi service by a plurality of SIM cards of the electronic equipment, and inquiring ePDG information by a static inquiring mode of local configuration or a dynamic inquiring mode of a domain name system (Domain Name System, DNS) to obtain an address inquiring 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, in the case that authentication requests initiated by a plurality of SIM cards fail, the ePDG address is queried, and an updated ePDG address is determined; and controlling the plurality of SIM cards to initiate an authentication request to the updated ePDG address.
If the authentication requests initiated by the plurality of SIM cards all fail, the ePDG information can be queried again through a static query mode of local configuration or a dynamic query mode of DNS so as to determine the updated ePDG address. And then controlling the plurality of SIM cards to initiate an authentication request to the updated ePDG address.
Next, step 220 is referred to.
Since the ePDG is invalid and cannot register the second SIM card of VoWiFi, the target ePDG address of the other first SIM card successfully registering VoWiFi can be preferentially tried, and the appropriate ePDG can be selected for trying. Because the target ePDG address is passed 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 passed by the authentication is greatly improved.
That is, by the multi-card priori method, the probability that each SIM card can successfully develop the service is assumed to be a, b, & gtn, n is a positive integer. The value range of each probability is 0, 1. When only one SIM card is used, the probability of failing to carry out VoWiFi service is 1-a; when two cards exist, the probability of failing to perform VoWiFi service is between [ (1-a) (1-b), 1-a ], and so on, only one card VoWiFi can be normally performed, and other cards can be considered to be normally performed. At the moment, the failure probability of the VoWiFi service is (1-a) (1-b) and (1-n), the more the number of cards is, the lower the failure probability is, so that the advantage of multiple cards is fully utilized, and the probability of successful development of the VoWiFi service under the condition of multiple cards of the mobile phone can be improved.
In step 220, the following steps may be specifically included:
determining a first operator to which a first SIM card belongs and a second operator to which a second SIM card belongs; and under the condition that the first operator is consistent with the second operator or the first operator and the second operator meet the preset contract conditions, controlling the second SIM card to initiate an authentication request to the target ePDG address.
As shown in fig. 3, in step 220, the following steps may be specifically included:
step 310, determining a first operator to which the first SIM card belongs and a second operator to which the second SIM card belongs.
In step 320, in case the first operator is consistent with the second operator, the second SIM card is controlled to initiate an authentication request to the target ePDG address.
That is, under the condition that 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, determining a first operator to which the first SIM card belongs and a second operator to which the second SIM card belongs.
And step 420, controlling the second SIM card to initiate an authentication request to the target ePDG address under the condition that the first operator and the second operator meet preset contract conditions.
That is, when the operators to which the first SIM card and the second SIM card belong to operators that sign contracts and mutually recognize each other, the second SIM card can be controlled to initiate an authentication request to the target ePDG address.
Therefore, when the electronic device comprises a plurality of SIM cards, as long as the SIM card (first SIM card) successfully registers VoWiFi, and when the first operator is consistent with the second operator or when the first operator and the second operator meet the preset contract conditions, other SIM cards (second SIM cards) can refer to the target ePDG address of the first SIM card to initiate VoWiFi registration. Because the electronic equipment knows the target ePDG addresses selected by all the SIM cards successfully registered with the VoWiFi, the second SIM card incapable of registering the VoWiFi due to the unavailability of the ePDG addresses can select the target ePDG addresses which are authenticated and pass the priori, and a new request is initiated, so that the access success rate and the access efficiency of the VoWiFi can be greatly improved, and the user experience is improved.
In another possible embodiment, after step 220, the following steps may be further included:
under the condition that the second SIM card fails to initiate the authentication request to the target ePDG address, the ePDG address of the second SIM card is queried again in the authentication result, the updated ePDG address of the second SIM card is determined, and the updated ePDG address is the ePDG address which passes the authentication request except the target ePDG address in the authentication result; and controlling the second SIM card to initiate an authentication request to the updated ePDG address.
The second SIM card in the electronic device, which cannot register VoWiFi with the invalid ePDG, may first try the target ePDG address, if the second SIM card also fails to initiate the authentication request to the target ePDG address, the ePDG address of the second SIM card may be queried again, and the ePDG address through which the authentication request except the target ePDG address passes, that is, the updated ePDG address of the second SIM card, is determined from the authentication result. And then controlling the second SIM card to initiate an authentication request to the updated ePDG address.
In addition, if the second SIM card also fails to initiate the authentication request to the updated ePDG address, the ePDG address may be queried again according to the original static query or dynamic DNS query, the updated ePDG address is determined, and then the second SIM card is controlled to initiate the authentication request to the updated ePDG address.
In summary, in the embodiment of the present application, the target ePDG address based on the voice service VoWiFi of wireless fidelity and passing authentication is registered by acquiring the first SIM card, and then the second SIM card is controlled to initiate the authentication request by the target ePDG address. Because 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 improved, so that the time of interaction with a network can be reduced, and the efficiency of accessing VoWiFi service is improved.
