The network access method according to an embodiment of the present application, as shown in FIG. 3, includes

steps

301 and 302.

In step 301, the terminal acquires the target network parameters from the server through the identification card.

In step 302, the terminal accesses the target network according to the target network parameters.

Here, in actual application, the identification card may be a virtual identification card or a physical identification card. Taking the virtual identification card as an example, the virtual identification card includes but is not limited to: VSIM (Virtual Subscriber Identification Module, virtual SIM) card, eSIM (Embedded SIM, embedded SIM) card, SoftSIM (Soft Subscriber Identification, Module), soft customer identification module) At least one of a card and a UICC (Universal Integrated Circuit Card, virtual universal integrated circuit) card.

The eSIM card is essentially a SIM card, but it is directly embedded in the circuit board of the terminal device, and its size is much smaller than the smallest Nano currently. eSIM can support different operators through remote programming, and can switch between different operator networks. SoftSIM is a pure software solution for traditional physical SIM cards. It has the advantages of no hardware cost and can dynamically update SIM card parameters to support different operators. VSIM is an evolved version of SoftSIM, with higher security. It does not download authentication parameters such as Key (Key, Identifier) to the local, but performs authentication on the server.

In practical applications, the operator of the identification card and the operator of the target network may be the same or different.

Whether the virtual identification card or the physical identification card, when the operator to which the network it can access belongs to is the same as the operator to which the identification card belongs, the target network parameter directly downloaded by default through the identification card (virtual identification card or physical identification card) The target network parameter of the target network supported by the operator to which the identification card belongs to access the target network according to the target network parameter. For example, if the operator to which the identification card belongs is China Mobile, when the operator of the network it can access is also China Mobile, the target network parameter that the identification card directly downloads by default is the network parameter of China Mobile. According to the embodiment of the present application, because the default direct download is the network parameters of the same operator's network as the operator of the identification card, thereby eliminating the need to store the operator list in the stored operator list according to the identification card's operator attributes in related technologies. The process of finding the appropriate operator.

When the operator network that the identification card (virtual identification card or physical identification card) can access is different from the operator to which the card belongs, it is necessary to determine whether the operator network that can be accessed and the operator to which the identification card belongs have signed authorizations with each other. That is, whether there is subscription information authorized to access the network, and if the subscription information exists, the target network parameters of the authorized operator can be downloaded based on the subscription information.

In practical applications, the target network can be in various forms, such as a VoLTE network, a VoWiFi (Voice over WiFi, WiFi-based voice) network, a 5G network, or an RCS (Rich Communication, Suite, converged communication) network, etc. Correspondingly, different target networks have different network parameters.

When the target network is a VoLTE network, the target network parameters obtained from the server are VoLTE parameters. When the target network to be accessed is a VoWiFi network, the target network parameters obtained from the server are WiFi parameters. When the target network to be accessed is a 5G network, the target network parameter obtained from the server is the VoNR (Voice Over New Radio) parameter. When the target network to be accessed is an RCS network, the target network parameters acquired from the server include at least one of VoLTE parameters, WiFi parameters, and VoNR parameters.

The RCS network is an application scenario that can integrate the above-mentioned VoLTE, VoWiFi, 5G network and other scenarios. Its biggest feature is the realization of service integration, that is, the integration of many services such as SMS, voice, call, MMS, and video sharing. A protocol framework (such as based on IMS (IP Multimedia Subsystem, IP Multimedia Subsystem)) performs transmission and communication, and at the same time realizes business expansion.

In practical applications, when the identification card is a virtual identification card, the terminal needs to apply for card information from the operator in order to be able to access the network and perform various network services through the identification card.

In an embodiment, as shown in FIG. 4, the method may further include steps 300 to 302.

In step 300, the terminal applies to the first operator network for a virtual identification card.

After the terminal successfully applies for the virtual identification card from the first operator's network, it can obtain card parameters (which can also be understood as card information) so that it can access the network through the virtual identification card.

Here, in practical application, the VSIM card is a commonly used virtual identification card. When the virtual identification card is a VSIM card, the following two situations will occur: in the first case, the first operator to which the virtual SIM card belongs and the second operator to which the target network belongs are the same operator; in the second case, the virtual The first operator to which the SIM card belongs and the second operator to which the target network belongs are different operators.

Of course, for other types of virtual identification cards and physical identification cards, the above two situations will also occur.

For the first case, no authorization judgment is required before access, and the target network is directly accessed according to the target network parameters obtained from the server through the VSIM card. At this time, the process for the terminal to access the network, as shown in FIG. 5, includes steps 501 to 503.

In step 501, the terminal obtains the target network parameters from the server through the VSIM identification card.

In step 502, it is determined that the operator to which the VSIM card belongs and the operator to which the target network belongs are the same target operator.

In step 503, the target network is accessed according to the target network parameters acquired from the server through the VSIM card.

Specifically, assuming that the target network is a VoLTE network, no VoLTE parameters of any operator are preset on the terminal side before leaving the factory. Instead, the terminal applies to the operator ’s network for the operator ’s VSIM card, and uses the VSIM card from the server ( The server can be an operator ’s server or a third-party server that has purchased multiple operators ’number segments) Download the operator ’s VoLTE parameters to adaptively access the operator ’s VoLTE network . In the related art, VoLTE parameters come from the terminal's local database. According to the embodiment of the present application, the VoLTE parameters are provided by the server, and may be delivered to the terminal along with the VSIM card parameters. Of course, the server may also only provide the VoLTE parameters to the terminal. VoLTE parameters refer to the parameters that the terminal needs to use when performing the VoLTE service, and are generally provided by the operator. For example, voice coding method, IPSec encryption algorithm, whether to support VoLTE, etc. VSIM card parameters refer to those parameters that were originally stored in the physical SIM card, including but not limited to MCC (Mobile Country Code), MNC (Mobile Network Code, mobile network number), IMSI (International Mobile Subscriber Identity) , International Mobile Subscriber Identification Number), ICCID (Integrate Circuit Card Identity, integrated circuit card identification code), Ki, FPLMN (Forbidden PLMN, Forbidden Home Network), HPLMN (Encrypted Data Transfer between SIM Card and Operator) Home PLMN, the public land mobile network to which the end user belongs), etc.

In addition, as described above, when the first operator to which the virtual SIM card belongs and the second operator to which the target network belongs are the same operator, the solution of the embodiment of the present application can be used to eliminate The operator attribute matches the process of searching for a suitable operator in the stored operator list, which simplifies the processing process and greatly accelerates the processing speed.

As for the first case, in the VoLTE scenario, as shown in FIG. 6, the method flow of the terminal accessing the network according to the embodiment of the present application includes steps 601 to 603.

In step 601, the terminal applies to the first operator network for a VSIM card.

In step 602, the terminal obtains the VoLTE parameters of the VoLTE network of the first operator through the VSIM card.

In step 603, the terminal accesses the VoLTE network according to the VoLTE parameters.

Considering security, in order to avoid theft of the applied VSIM card, the terminal may obtain a random number after applying for the VSIM card from the first operator network. The terminal may send the random number to the first operator network, and after the identity verification performed by the first operator network according to the random number, obtain the VoLTE parameters of the VoLTE network through the VSIM card.

More specifically, the method for the terminal to access the network according to the embodiment of the present application, as shown in FIG. 7, includes steps 701 to 704.

In step 701, the terminal applies to the first operator network for a VSIM card and obtains a random number.

For example, an end user can obtain a random number from the server after applying for a VSIM card to complete payment.

In step 702, the terminal sends the random number to the first operator network.

In step 703, the first operator network compares the random number stored locally on the network side with the random number received from the terminal. If the two random numbers are consistent, the identity verification is successful.

In step 704, after the identity verification is successful, the terminal obtains the VoLTE parameters of the VoLTE network of the first operator through the VSIM card.

Another security mechanism is encryption, that is, the terminal applies for a VSIM card from the operator's network, the terminal obtains the encrypted "SIM card parameters and VoLTE parameters" from the server through the VSIM card, and the terminal uses the encrypted "SIM card parameters and VoLTE parameters" "Stored on the terminal side, and after decrypting it, get" SIM card parameters and VoLTE parameters ", and then access the target network according to" SIM card parameters and VoLTE parameters ".

Specifically, when the terminal leaves the factory, the terminal side does not preset any operator's VoLTE parameters in the software version. The terminal applies for the target operator's VSIM card, downloads the encrypted VSIM card parameters and the operator's VoLTE parameters from the server, and decrypts Therefore, when it is determined that the operator to which the VSIM card belongs and the operator to which the VoLTE network belongs are the same target operator according to the VSIM card parameters, the terminal uses the VoLTE parameters provided by the server to successfully access the VoLTE network of the operator. In this embodiment, the VoLTE parameters are the latest VoLTE parameters of the target operator that are dynamically acquired.

For the second case, the first operator to which the VSIM card belongs is different from the second operator to which the target network belongs. In this case, it is necessary to perform authorization judgment before accessing the target network. If it is authorized, the target network can be accessed according to the parameters of the target network; otherwise, it means that unauthorized access to the target network fails. The authorization judgment can be performed with the help of the VSIM card identifier in the VSIM card parameters. That is to say, the card parameters of the virtual SIM card applied to the first operator at least include the SIM card identification, and the terminal sends the SIM card identification to the target network and receives a feedback message from the target network, the feedback message is used to indicate The virtual SIM card of the terminal obtains the target network access authorization, and then the terminal accesses the target network according to the feedback message and the target network parameters.

At this time, the specific process of the terminal accessing the network, as shown in FIG. 8, includes steps 801 to 805.

In step 801, the terminal obtains the target network parameters from the server through the VSIM card.

In step 802, it is determined that the operator to which the VSIM card belongs and the operator to which the target network parameter belongs are different target operators.

In step 803, the target network side performs authorization judgment before accessing the target network. If it is authorized, step 804 is performed; otherwise, it indicates that it is not authorized, and step 805 is performed.

In step 804, the terminal accesses the target network according to the target network parameters acquired from the server through the VSIM card.

In step 805, the terminal fails to access the target network.

In actual application, when judging whether to authorize, the target network can use the VSIM card identifier to obtain whether the terminal's contract information has authorization information, based on which it can be judged between the operator to which the VSIM card belongs and the operator to which the target network parameters belong Whether there is authorization for network access. Card identification includes but is not limited to IMSI. IMSI is a mark to distinguish mobile users. Its total length does not exceed 15 digits. You can use 0-9 to represent valid information (valid information for distinguishing mobile users).

In practical applications, the user can be presented with a list of authorized target networks so that the user can choose according to their needs. Based on this, in an embodiment, as shown in FIG. 9, step 302 may include steps 901 to 903.

In step 901, a list of target networks to which the identification card is authorized is displayed.

In step 902, the target network to be accessed is selected from the target network list.

In step 903, the target network parameters of the target network to be accessed are acquired from the server.

As for the second case, according to an embodiment of the present application, a process for a terminal to acquire target network parameters from a server through an identification card, as shown in FIG. 10, includes steps 1001 to 1002.

In step 1001, a list of target networks that can be authorized to access the network matching the VSIM card is displayed on the terminal.

In step 1002, the user selects a target network from the target network list, and after receiving the user's selection operation, the terminal acquires target network parameters corresponding to the target network.

Specifically, this is a way to present authorization information through the interface. For example, a Unicom ’s VSIM card has obtained the network access authorization, and the current terminal is under the coverage of the mobile network, and needs to access the mobile network. After selecting the mobile network, the target network parameters of the corresponding mobile network are downloaded from the server in order to Access the mobile network according to the downloaded target network parameters.

In the second case, when the current location of the terminal is the roaming place, the operator information to be accessed can be obtained from the base station of the roaming place, so that the target network parameters can be quickly obtained from the server.

Based on this, according to an embodiment of the present application, the process for the terminal to obtain the target network parameters from the server through the identification card, as shown in FIG. 11, includes steps 1101 to 1103.

In step 1101, the current location information of the terminal is acquired.

In step 1102, the operator information of the accessible target network is acquired from the base station within the network coverage distance corresponding to the location information.

In step 1103, the target network parameters corresponding to the operator information are obtained from the server through the VSIM card.

Here, in actual application, the location information can be obtained through the positioning system. After the location information is obtained, information of nearby base stations can be obtained according to the location information, so that operator information can be obtained from the base station.

In practical applications, operator information refers to information that can identify an operator, such as MCC and MNC. The terminal can compare the MCC and MNC in the parameters of the VSIM card with the MCC and MNC obtained from the base station, so that it can know whether the terminal is roaming.

When the terminal is in a roaming place, in the related art, network switching needs to be performed according to operator information such as the country code obtained from the base station, and the switching process is quite cumbersome. According to the embodiment of the present application, when the terminal is in the roaming place, it does not need to be based on MCC Waiting for the network switching process greatly speeds up the network access speed and improves the user experience.

According to the embodiment of the present application, the problem of low success rate of target network access during the adjustment of the target network parameter of the server itself or international roaming is solved, and the user experience is greatly improved. In the case of international roaming, using the above various embodiments, the terminal can dynamically obtain the target network parameters from the server according to the identification card. The target network parameters do not need to be preset in advance on the terminal side and pre-binding with the identification card, which saves Storage space on the terminal side. At the same time, the target network parameters obtained from the server are always the latest parameters, so access to the target network will not fail due to the network parameters, which ensures that the terminal successfully accesses the network.

An embodiment of the present application further provides a terminal for implementing the above network access method, and the content that has been described will not be described in detail. As used below, the term "module" may be implemented as a combination of software and / or hardware with predetermined functions. Although the devices described in the following embodiments are preferably implemented in software, implementation of hardware or a combination of software and hardware is also possible and conceived.

It should be noted that the technical solutions described in the embodiments of the present application can be arbitrarily combined without conflict.

The embodiments of the present application will be described in detail below with reference to the drawings.

In this embodiment, taking VoLTE as an example, a method of dynamically acquiring VoLTE parameters of a server through a VSIM card is implemented, so as to adaptively access a VoLTE network. Specifically, the terminal side no longer presets VoLTE parameters of any operator before leaving the factory, but after applying for a VSIM card, downloads the VoLTE parameters of the operator from the server through the VSIM card to access the VoLTE network.

In an exemplary embodiment, FIG. 14 is a schematic diagram of an optional structure of a terminal applying the method of the foregoing embodiment. As shown in FIG. 14, the terminal of the present application includes a detection module 141, an application module 142, a download module 143, a storage module 144, a configuration module 145, and a query module 146. The detection module 141 is used to detect whether the VSIM card parameters and VoLTE parameters of a certain operator are stored locally within the validity period. The application module 142 is used to apply for the VSIM card number and VoLTE parameters of an operator from the server. The download module 143 is used to download the VSIM card parameters provided by the server and the VoLTE parameters of the operator. The storage module 144 is used to save the downloaded VSIM card parameters and VoLTE parameters locally, and based on the consideration of information security, the encryption mode is used. The configuration module 145 is used to parse and save the local VoLTE parameters and write them into the NV or file actually used by the terminal. The query module 146 is used to query whether the VoLTE switch of the terminal is turned on.

For example, the VoLTE parameters read by the configuration module 145 are as follows:

AMR_WB = 1

IPSec = 0

ViLTE = 0

The configuration module 145 analyzes and learns that the operator's VoLTE network requires the terminal to turn on adaptive AMR-WB (Adaptive Multi-Rate Wideband, multi-rate wideband coding) voice coding, and turn off IPSec (IP Security, IP security) authentication and ViLTE Video over LTE, LTE-based video calling). Therefore, the configuration module 145 modifies the NV or file corresponding to the above function points.

In an exemplary embodiment, FIG. 15 is a procedure for adaptively accessing a VoLTE network based on a VSIM card using this embodiment. The procedure includes the following steps 1501 to 1509.

In step 1501, the terminal successfully accesses the LTE network.

In step 1502, the notification detection module 141 detects whether the virtual SIM card parameters and VoLTE parameters of the operator's validity period are stored locally.

Here, if the parameters within the validity period are not stored, step 1503 is continued; otherwise, step 1507 is executed.

In step 1503, the notification application module 142 applies to the server for the operator's VSIM card number and VoLTE parameters.

In step 1504, the download module 143 is notified to download the VSIM card parameters provided by the server and the VoLTE parameters of the operator.

In step 1505, the storage module 144 is notified to save the downloaded parameters locally.

In step 1506, the notification configuration module 145 parses and saves the local VoLTE parameters and writes them to the NV or file actually used by the terminal.

In step 1507, the notification query module 146 queries whether the VoLTE switch of the terminal is turned on.

Here, if the switch is turned on, step 1508 is continued; otherwise, step 1509 is executed.

At step 1508, VoLTE registration is initiated.

At step 1509, the session ends.

In this embodiment, the detection module 141 is used to detect whether the virtual SIM card parameters and VoLTE parameters of a certain operator are stored locally. From the current development trend of smart terminals, the existence of physical SIM cards partially limits the evolution of mobile terminals, limits the space and design of devices, and increases the process difficulty and manufacturing costs of devices. Therefore, the major smart terminal manufacturers began to resolve to vigorously promote the virtual SIM technology.

VoLTE parameters refer to the parameters that the terminal needs to use when performing the VoLTE service, and are generally provided by the operator. For example, voice coding method, IPSec encryption algorithm, whether to support ViLTE, etc.

It can be seen that this refers to the VSIM card parameters and VoLTE parameters of the same operator. For example, after applying for the virtual SIM card number of China Unicom, the terminal downloads the SIM card parameters of the number and the VoLTE parameters of China Unicom from the server. The embodiment of the present application omits the process of matching VoLTE parameters of the operator in the software version according to the PLMN of the physical SIM card in the related art.

In this embodiment, VoLTE is used as an example, but actual applications include, but are not limited to, parameters related to operators such as VoLTE, VoWiFi, RCS, and 5G services.

In an exemplary embodiment, the application module 142 is used to apply for VSIM card parameters and VoLTE parameters to the server. The server may be a server of an operator, or a third-party server that has purchased a number segment of multiple operators.

The flow chart of the interaction between the application module 142 and the server is shown in FIG. 16, and the process includes the following steps 1601 to 1604.

In step 1601, the terminal applies to the server for the VSIM card and VoLTE parameters of an operator.

In step 1602, the terminal receives an instruction from the server requesting "identity verification".

In step 1603, the terminal sends the device identification of the terminal to the server, requesting verification of the identity of the terminal.

Here, the device identification of the terminal is used for identity verification when downloading the SIM card parameters and VoLTE parameters to determine that the terminal has applied for the above-mentioned virtual SIM card, so as to ensure the security of the SIM card parameters and VoLTE parameter download corresponding to the SIM card Sex. The device identification of the terminal can also be used as an encryption factor for these SIM card parameters and VoLTE parameters.

In step 1604, after the identity verification of the terminal by the server is passed, the terminal receives the "successful application" message returned by the server, and the application obtains the VSIM card and VoLTE parameters.

Here, during the application process, the download module 143 is used to download the virtual SIM card parameters and VoLTE parameters provided by the server, and send a "download complete message" to the server after the download is completed. In addition, when these parameters are encrypted, the VSIM card parameters and VoLTE parameters are obtained after the download is completed and decrypted.

In an exemplary embodiment, for the sake of security, a random number is further added, and a flowchart of the interaction between the application module 142 and the server is shown in FIG. 17.

In step 1701, the terminal applies to the server for the VSIM card of an operator.

In step 1702, the terminal receives an instruction from the server requesting "identity verification".

In step 1703, the terminal sends the device identification of the terminal to the server, requesting verification of the identity of the terminal.

In step 1704, after the identity verification of the terminal by the server is passed, the VSIM card is applied for and the random number sent together.

The random number can be used for identity verification when downloading the SIM card parameters and VoLTE parameters to determine whether it is the terminal that owns the virtual SIM card to download the SIM card parameters and VoLTE parameters, so as to ensure the SIM card parameters and VoLTE corresponding to the SIM card Parameter download security. Random numbers can also be used as encryption factors for these SIM card parameters and VoLTE parameters.

The terminal receives the "successful application" message returned by the server and applies for a virtual SIM card so that subsequent terminals can download the SIM card parameters and VoLTE parameters from the server through the virtual SIM card.

In an exemplary embodiment, for security reasons, a random number is further added. The interaction process between the application module 142, the download module 143 and the server is shown in FIG. 18, and the process includes the following steps 1801 to 1805.

In step 1801, the terminal (application module 142) requests the server to download the VSIM card parameters and VoLTE parameters of an operator.

In step 1802, the terminal (application module 142) receives an instruction from the server requesting "identity verification".

In step 1803, the terminal (application module 142) sends the device identification and random number of the terminal to the server to request identity verification.

In this step, only random numbers may be sent. In the previous application process, the random number was obtained only after the terminal identity verification was achieved through the device identification of the terminal, so it is also safe to send only the random number.

The terminal sends the device identification and random number of the terminal to the server, or the terminal only sends the random number to the server, to verify the identity when downloading the SIM card parameters and VoLTE parameters, to determine that the terminal applied for the virtual SIM card, thus Ensure the security of the SIM card parameters and VoLTE parameter download corresponding to the SIM card.

In step 1804, the terminal (download module 143) receives the VSIM card parameters and VoLTE parameters sent by the server.

In step 1805, the terminal (download module 143) sends a "download complete" message to the server.

In an exemplary embodiment, the authorization judgment process before accessing the network is shown in FIG. 19, and the process includes the following steps 1901 to 1904.

In step 1901, the terminal sends a VoLTE registration message to the P-CSCF (Proxy-Call Session Control Function) network element.

In step 1902, the P-CSCF network element queries the HSS (Home Subscriber Server, Home Subscriber Server) server where the SIM card is located according to the IMSI in the SIM card to obtain the VoLTE authorization.

There are two cases here: P-CSCF network element and HSS network element belong to the same operator; or P-CSCF network element and HSS network element do not belong to the same operator.

The IMSI is stored in the SIM card and is the unique identifier of the SIM card (including the virtual SIM card and the physical SIM card).

The P-CSCF is a network element on the network side, and the VoLTE signaling interaction between the terminal and the SIP server must pass through the P-CSCF. The HSS is also a network element on the network side and is used to store user subscription information.

In step 1903, the HSS network element queries the authorization information according to the stored user subscription information and then instructs the P-CSCF network element through instructions, so that the P-CSCF inquires that the SIM card has obtained the VoLTE authorization.

In step 1904, the terminal successfully registers with the VoLTE network.

As can be seen from the above description, using the solution of this embodiment improves the versatility of software versions, greatly reduces the number of software versions, shortens the software development and testing cycle, and reduces costs. Solve the problem of low network access parameter adjustment or low service access success rate and low interoperability success rate during network side parameter adjustment or international roaming Provided help and greatly improved the user experience. It also provides more possibilities for the development of identification card business.

In addition, operators can flexibly configure different network service parameters according to user categories, terminal categories, and service categories.

Although the embodiments of the present application have been disclosed for illustrative purposes, those skilled in the art will realize that various improvements, additions, and substitutions are also possible, and therefore, the scope of the present application should not be limited to the above-described embodiments.
