in order to make the technical solutions of the present invention better understood by those skilled in the art, the technical solutions in the embodiments of the present invention will be clearly described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. 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 invention.
The appearances of the phrases "first," "second," and "third," or the like, in the specification, claims, and figures are not necessarily all referring to the particular order in which they are presented. Furthermore, the terms "include" and "have," as well as any variations thereof, are intended to cover non-exclusive inclusions. For example, a process, method, system, article, or apparatus that comprises a list of steps or elements is not limited to only those steps or elements listed, but may alternatively include other steps or elements not listed, or inherent to such process, method, article, or apparatus.
In one embodiment of the present invention, the method for accessing a network includes: an access point sends a probe message, wherein the probe message contains the VoWiFi (Voice over WiFi) capability of the access point based on wireless fidelity so that a terminal determines whether to access the access point according to the VoWiFi capability of the access point; the access point receives a request for accessing the access point, which is initiated by the terminal; and the access point establishes connection with the terminal according to the request. It should be noted that VoWiFi is an access network, and ultimately is to access IMS (IP multimedia subsystem), which is an IP voice service that an operator can control and manage.
As shown in fig. 1, fig. 1 is a flowchart illustrating a method for accessing a network according to an embodiment of the present invention. As shown in fig. 1, a method for accessing a network according to an embodiment of the present invention includes the following steps:
101. A wireless fidelity WiFi access point sends a detection message, wherein the detection message contains the VoWiFi capability of the access point based on the voice communication of wireless fidelity so that a terminal can determine whether to access the access point according to the VoWiFi capability of the access point;
the capability of VoWiFi may be the strength of the signal.
It should be noted that the access point is voice over wifi (voice over wifi) based on wifi.
it can be understood that the Probe message sent by the VoWiFi access point may be a beacon frame or a Probe Response message; wherein the beacon frame or the Probe Response Probe Response message carries a VoWiFi capable field.
Therein, it is understood that a VoWiFi access point may be a field that adds the capability of accessing VoWiFi in a broadcast frame.
102. The access point receives a request for accessing the access point, which is initiated by the terminal;
The terminal actively scans surrounding access points, receives a detection message sent by the access points, determines that the access point has VoWiFi capability according to the detection message, and sends an access request to the access point when the access point has VoWiFi capability.
103. and the access point establishes connection with the terminal according to the request.
optionally, before establishing the connection, the access point authenticates the terminal. For example, the Authentication of the terminal by the VoWiFi network uses an EAP-AKA (advanced Extensible Authentication Protocol Method for 3rd generation Authentication and Key Agreement) mechanism, and completes the Authentication Authorization through an AAA (Authentication, Authorization, Accounting) server. Therefore, for the public trusted VoWiFi hotspot, the corresponding WiFi router needs to be configured into an EAP-AKA authentication mode, namely, the authentication and authentication process is completed through the SIM card and the AAA server, and the whole process does not need the user to input a password, but needs the user to manually select the corresponding hotspot to initiate connection. For example, the request for accessing the access point includes an authentication vector of a subscriber identity module SIM card of the terminal; the access point establishes connection with the terminal according to the request, and the method comprises the following steps: the access point verifies the terminal according to the authentication vector of the SIM card; and when the verification is passed, the access point establishes connection with the terminal.
it can be seen that, in the solution of this embodiment, an access point sends a probe message, where the probe message includes the capability of the access point based on the voice over wifi of wifi so that a terminal determines whether to access the access point according to the capability of the access point based on the VoWiFi; the access point receives a request for accessing the access point, which is initiated by the terminal; and the access point establishes connection with the terminal according to the request. Therefore, the access point sends the detection message containing the VoWiFi capability of the access point, and the terminal quickly identifies and accesses the VoWiFi according to the detection message, so that the user experience is improved.
as shown in fig. 2, fig. 2 is a flowchart illustrating a method for accessing a network according to an embodiment of the present invention. As shown in fig. 2, a method for accessing a network according to an embodiment of the present invention includes the following steps:
201. A terminal scans a wireless fidelity WiFi network access point within a preset range to acquire a detection message sent by the access point, wherein the detection message comprises the voice communication VoWiFi capacity based on wireless fidelity of the access point;
the capability of VoWiFi may be the strength of the signal.
When the terminal actively scans the access points, the access points actively send Probe requests to the access points, and after the access points receive the Probe requests, the access points send Probe Response or Beacon frames back to the terminal. And the terminal resolves the VoWiFi capability from the Beacon frame or the Probe Response when receiving the Beacon frame or the Probe Response.
202. And the terminal selects the access point with the scanned VoWiFi capability larger than the preset threshold value to connect.
before the terminal selects the scanned access point with the strongest VoWiFi capability to connect to, the method further includes:
The terminal determines a VoWiFi list according to the VoWiFi capacity of the access point;
And the terminal determines the access points with the VoWiFi capacity larger than a preset threshold value in the VoWiFi list.
It can be seen that, in the scheme of this embodiment, a terminal scans a WiFi network access point within a preset range to obtain the capability of the access point based on the voice communication VoWiFi guaranteed wirelessly; and the terminal selects the access point with the scanned VoWiFi capability larger than the preset threshold value to connect. Therefore, the terminal selects the access point with the scanned VoWiFi capability larger than the preset threshold value to connect, so that the terminal can be quickly connected to the VoWiFi with better signals, and the user experience is improved.
as shown in fig. 3, fig. 3 is a flowchart illustrating a method for accessing a network according to an embodiment of the present invention. As shown in fig. 3, a method for accessing a network according to an embodiment of the present invention includes the following steps:
301. The terminal receives a detection message sent by a wireless fidelity WiFi network access point within a preset range; wherein the detection message includes VoWiFi (Voice over WiFi) capability of the access point;
the detection message may be a broadcast message, and the broadcast message includes a field for indicating the capability of the VoWiFi;
302. the terminal determines a VoWiFi list according to the received VoWiFi capability of the access point;
for example, when the terminal receives probe messages sent by a plurality of networks, the terminal can determine the VoWiFi capability of each access point according to the probe messages, and then determine a VoWiFi list according to the VoWiFi capability of each access point; wherein the format of the VoWiFi list may be: WiFi network identification and VoWiFi capability size.
303. The terminal determines the access point of which the VoWiFi capacity is greater than a preset threshold value in the VoWiFi list;
the capability of VoWiFi may be the strength of the signal.
For example, assuming a 5-bit strongest signal, the preset threshold is a 3-bit signal. For another example, assuming the strongest signal of 3 bits, the predetermined threshold is 2 bits. There are many ways to measure the ability, which are not exemplified here.
304. and the terminal selects an access point with the VoWiFi capacity larger than a preset threshold value to connect.
Wherein, the connection process can complete authorization authentication through the AAA server through an EAP-AKA mechanism. Therefore, for the public trusted VoWiFi hotspot, the corresponding WiFi router needs to be configured into an EAP-AKA authentication mode, namely, the authentication and authentication process is completed through the SIM card and the AAA server, and the whole process does not need the user to input a password, but needs the user to manually select the corresponding hotspot to initiate connection. For example, the terminal sends a connection request to the access point, where the request includes an authentication vector of a subscriber identity module SIM card of the terminal; the access point verifies the terminal according to the authentication vector of the SIM card; and when the verification is passed, the access point establishes connection with the terminal.
It can be seen that, in the scheme of this embodiment, the terminal receives a probe message sent by a WiFi network within a preset range; wherein the detection message includes VoWiFi (Voice over WiFi) capability of the access point; the terminal determines a VoWiFi list according to the received VoWiFi capability of the access point; the terminal determines the access point of which the VoWiFi capacity is greater than a preset threshold value in the VoWiFi list; and the terminal selects an access point with the VoWiFi capacity larger than a preset threshold value to connect. Therefore, the terminal determines the access point with the VoWiFi capability by receiving the detection message sent by the WiFi network, and selects the access point with the VoWiFi capability larger than the preset threshold value to connect, so that the terminal can be quickly connected to the VoWiFi with better signal, and the user experience is improved.
In another embodiment of the present invention, the present invention provides a method for a terminal to automatically select a VoWiFi-capable access point for access. The basic principle is that when a VoWiFi hotspot (access point) sends a beacon frame or a Probe Response detection Response message, the VoWiFi hotspot access capability is carried, the terminal detects the VoWiFi capability of each hotspot during scanning, automatically screens a VoWiFi hotspot list, selects the hotspot according to the optimal signal value and automatically initiates a connection process. By the scheme of the invention, the terminal can automatically select the VoWiFi hotspot to access the IMS (IP Multimedia Subsystem), can prevent the interference of the non-VoWiFi hotspot to the user, does not need the manual selection of the user, and increases the user experience. Among them, it is pointed out that: IMS is a new form of multimedia service that can meet the demands of modern, more diverse multimedia services for the end-users today.
