All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present application.
The terms first, second and the like in the description and in the claims of the present application are used for distinguishing between similar elements and not necessarily for describing a particular sequential or chronological order. It is to be understood that the data so used is interchangeable under appropriate circumstances such that the embodiments of the application are capable of operation in sequences other than those illustrated or described herein. In addition, "and/or" in the specification and claims means at least one of connected objects, a character "/" generally means that a preceding and succeeding related objects are in an "or" relationship.
The network access method provided in the embodiment of the present application can be applied to the following application scenarios, which are described below.
At present, multiple SIM cards can be installed in an electronic device with multiple card slots, so that a user can experience services of different operators while owning one electronic device, and challenges are brought to some services.
Among them, a Voice over Wi-Fi (VoWiFi) service based on Wi-Fi is a relatively common service for electronic devices. VoWiFi has five different network architectures, is widely applied 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.
In the non-trusted domain EPC access scheme, all Wi-Fi (WIreless-Fidelity) hotspots and other non-trusted domain devices can access, and access to a PDN Gateway (PDN Gateway, PGW) through an evolved Packet Data Gateway (ePDG) to implement interworking with the EPC. Since the S2b interface is adopted for interworking between the untrusted domain access network and the EPC, this networking is also referred to as an S2b interface networking scheme. The scheme has no reconstruction requirement on the WLAN, has high safety, supports seamless switching and solves the continuity problem of voice and data services.
The scheme well utilizes the existing wireless network, and the VoWiFi function can be realized only by simple modification on the basis of the original network, so the scheme is greatly supported by operators and electronic equipment manufacturers. In the scheme, the electronic device is accessed to a mobile Network trusted by an operator through an untrusted Wireless Network, and the PGW is used as an anchor point for switching between a Wireless Local Area Network (WLAN) and a Long Term Evolution (LTE). The PGW is an important network element in the EPC of the mobile communication network. The PGW is a border gateway of the EPC network, and provides functions of session management and bearer control, data forwarding, network protocol address allocation, and the like for a user.
Based on the networking scheme of the S2b interface, after a series of authentication, services such as voice, video and short message can be realized. The development of the VoWiFi service only needs to add an ePDG and an Authentication, Authorization, and Accounting (3 GPP AAA) network element, where the ePDG can be regarded as a connection supporting network element between the VoWiFi network and the PGW. The terminal SWu interface is connected with a terminal SWu interface of a non-trusted WiFi network, interacts with electronic equipment through Internet key exchange protocol (IKEv2) messages, acquires authentication information of the electronic equipment, and interacts the authentication information with 3GPP AAA, so that user authentication and authentication are completed. The user data transmitted by the electronic device through an Internet Protocol Security (IPSec) tunnel is decapsulated, and the user data after being repackaged is transmitted through a GTP tunnel between the electronic device and the PGW.
Therefore, the ePDG plays a pivotal role in connecting the untrusted WiFi network and the PGW network element. The selection of ePDG has a great impact on the launch of VoWiFi services.
For an electronic device comprising a plurality of SIM cards, assume that the probability that each SIM card can successfully conduct a service is a, b, n is a positive integer. The value range of each probability is [0,1 ]. When only one SIM card is available, the probability of successfully carrying out 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, and as the number of SIM cards in the electronic device is larger, the probability of successfully performing the VoWiFi service is lower.
Aiming at the problems in the related art, the embodiments of the present application provide a network access method and apparatus, so as to solve the problem in the related art that as SIM cards increase, the access efficiency of the VoWiFi service is low.
The method provided by the embodiment of the application can be applied to any scene with low VoWiFi service access efficiency along with the increase of SIM cards besides the application scene.
By the method provided by the embodiment of the application, the target ePDG address which is registered by the first SIM card and passes the authentication based on the VoWiFi (voice over fidelity) voice service is obtained, and then the second SIM card is controlled to initiate the authentication request through 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 that the authentication request initiated by the second SIM card to the target ePDG address passes is greatly improved, so that the time of interaction with the network can be reduced, and the efficiency of accessing the VoWiFi service is improved.
Based on the above application scenarios, 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 can be connected to the ePDG300 through any WiFi wireless access point (i.e., the network 200). Then, the ePDG300 connects to the PGW 400; and finally accesses to IMS core network 500 through PGW 400. Since the electronic device 100 and the ePDG300 are a public network, there is an insecurity factor, and therefore an IPSec secure tunnel is established between the electronic device 100 and the ePDG300, the electronic device 100 may complete the identity authentication and IPSec establishment procedures through the IKEv2 protocol. After IPSec is established, the VoWiFi service can be registered with the IMS core network and subsequent service calling is carried out. Based on the scheme shown in fig. 1, all the devices in the non-trusted domain, such as Wi-Fi hotspots, can access the PGW through the ePDG, so as to implement the interworking with the core network. The scheme has no reconstruction requirement on the 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 VoWiFi (voice over fidelity) based voice service, inquiring an ePDG (internet protocol data distribution) address, and then controlling each SIM card to initiate an authentication request to the corresponding ePDG address; and controlling the second SIM card to initiate the authentication request to the target ePDG address passing the authentication request 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. Because the speed of acquiring the target ePDG address passed by the authentication request is far faster than the speed of re-inquiring the ePDG address, the probability that the authentication request initiated by the second SIM card to the target ePDG address passes is greatly improved, the time of interaction with the network can be further reduced, and the efficiency of accessing the VoWiFi service is improved.
Based on the 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 according to 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, and is specifically as follows:
step 210, a target ePDG address is obtained, where the target ePDG address is an ePDG address where VoWiFi is registered by the first SIM card and the first SIM card passes authentication.
Step 220, controlling the second SIM card to initiate an authentication request through the target ePDG address.
According to the network access method, the first SIM card is acquired to register the VoWiFi-based voice service and pass the target ePDG address of authentication, and then the second SIM card is controlled to initiate the authentication request through 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 that the authentication request initiated by the second SIM card to the target ePDG address passes is greatly improved, so that the time of interaction with the network can be reduced, and the efficiency of accessing the VoWiFi service is improved.
The following presents a simplified summary of the words involved in this application.
The SIM card is a subscriber identity card held by a Mobile subscriber of the Global System for Mobile Communications (GSM) System. The GSM system identifies the GSM subscriber by means of a SIM card. The same SIM card may be used on different electronic devices. The electronic equipment can be accessed to the network for use only after the SIM card is inserted. The SIM card is a key for the electronic device to connect to the GSM network, and after the electronic device is installed with the SIM card, various services provided by the network operator can be enjoyed.
The VoWiFi technology comes from the beginning, and the technology is to use the existing Wi-Fi (WIreless-Fidelity) network to realize WIreless VoIP voice call, so that a user can perform roaming voice and video call in the coverage of the WLAN network at any time through the VoWiFi electronic equipment. VoWiFi uses WiFi as an access network and eventually accesses IMS (IP Multimedia Subsystem), which is a voice over IP service that operators can control and manage. The VoWiFi technology is receiving more and more attention due to its low communication cost and the convenience of WLAN for users.
The contents of steps 210-220 are described below:
first, step 210 is involved.
In a possible embodiment, before step 210, the following steps may be further included:
obtaining 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 know which epdgs authenticated by the SIM cards are available according to the authentication result. That is, the target ePDG address corresponding to the first SIM card that the authentication request passes through may be determined as the authentication result. The first SIM card that passes the authentication request may register VoWiFi with the target ePDG address.
Before the above step of obtaining the authentication result of each SIM card initiating the authentication request to the ePDG address, the following steps may be further included:
responding to the VoWiFi access request of each SIM card, inquiring the ePDG address to obtain an address inquiry result; and controlling each SIM card to initiate an authentication request to the ePDG address corresponding to the address query result.
A plurality of SIM cards of the electronic device respectively initiate a VoWiFi service, and query the ePDG information through a locally configured static query manner or a dynamic query manner of a Domain Name System (DNS), so as to obtain an address query result. After the address query result is obtained, each SIM card may be controlled to initiate an authentication request to the ePDG address corresponding to the address query result.
In a possible embodiment, when authentication requests initiated by a plurality of SIM cards fail, an ePDG address is queried, and an updated ePDG address is determined; and controlling a plurality of SIM cards to initiate an authentication request to the updated ePDG address.
If the authentication requests initiated by the multiple SIM cards all fail, the ePDG information may be queried again in a locally configured static query manner or in a dynamic query manner of the DNS, so as to determine an 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 involved.
The second SIM card that cannot register VoWiFi due to the ePDG being invalid may preferentially try the target ePDG address of the other first SIM card that successfully registers VoWiFi, and select a suitable ePDG to try. Since the target ePDG address is 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 authenticated is greatly increased.
That is, by the above-mentioned multi-card prior method, it is assumed that the probability that each SIM card can successfully perform the service is a, b, ·, n is a positive integer. The value range of each probability is [0,1 ]. When only one SIM card is available, the probability that the VoWiFi service cannot be successfully carried out is 1-a; when two cards exist, the probability of the VoWiFi service being unable to be successfully carried out is between [ (1-a) (1-b) and 1-a ], and by analogy, only one card is needed to normally carry out the VoWiFi service, and other cards are considered to normally carry out the VoWiFi service. At the moment, the failure probability of the VoWiFi service is (1-a) (1-b) · (1-n), and the failure probability is lower as the number of cards is larger, so that the advantages of multiple cards are 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.
Wherein, in step 220, the following steps may be specifically included:
determining a first operator to which the first SIM card belongs and a second operator to which the second SIM card belongs; and controlling the second SIM card to initiate an authentication request to the target ePDG address under the condition that the first operator is consistent with the second operator or the first operator and the second operator meet a preset contract condition.
As shown in fig. 3, step 220 may specifically include the following steps:
in step 310, a first operator to which the first SIM card belongs and a second operator to which the second SIM card belongs are determined.
And 320, controlling the second SIM card to initiate an authentication request to the target ePDG address under the condition that the first operator is consistent with the second operator.
I.e. in case the first SIM card and the second SIM card belong to the same operator, the second SIM card may be controlled to initiate an authentication request to the target ePDG address.
In addition, as shown in fig. 4, step 220 may specifically include the following steps:
step 410, determine 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 a preset contract condition.
That is, in the case where the operators to which the first SIM card and the second SIM card belong to the operators that have contracted and mutually approve each other, the second SIM card may be controlled to initiate an authentication request to the target ePDG address.
Therefore, in the case that the electronic device includes a plurality of SIM cards, as long as one SIM card (first SIM card) successfully registers VoWiFi, and in the case that the first operator is consistent with the second operator, or in the case that the first operator and the second operator meet a preset contract condition, the other SIM cards (second SIM cards) can initiate VoWiFi registration by referencing the target ePDG address of the first SIM card. Because the electronic equipment knows the target ePDG addresses selected by all SIM cards successfully registering the VoWiFi, the second SIM card incapable of registering the VoWiFi due to unavailable ePDG addresses can select the target ePDG addresses authenticated a priori and initiate a new request, so that the access success rate and 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, re-inquiring the ePDG address of the second SIM card in the authentication result, and determining the updated ePDG address of the second SIM card, wherein 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, which cannot register VoWiFi in the invalid ePDG, in the electronic device may try the target ePDG address first, and if the second SIM card 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 that the authentication request passes except the target ePDG address, 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 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 that is registered by the first SIM card and passes authentication based on the voice service VoWiFi under the wifi is obtained, and then the second SIM card is controlled to initiate an authentication request through 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 that the authentication request initiated by the second SIM card to the target ePDG address passes is greatly improved, so that the time of interaction with the network can be reduced, and the efficiency of accessing the VoWiFi service is improved.
