Detailed Description
In order to make the objects, technical solutions and advantages of the present application more apparent, the present application is described in further detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present application and are not intended to limit the present application.
The BIP protocol data transmission method provided by the application can be applied to the application environment shown in fig. 1. Wherein the terminal 102 communicates with the server 104 via a network. The terminal acquires a channel opening command sent by a terminal intelligent card UICC, establishes connection with the server according to the channel opening command and enters a data sending waiting state; after entering a data sending waiting state, acquiring a data sending command sent by the UICC; sending the UICC data acquired according to the data sending command to the server 104, and entering a state of waiting for receiving the server data; after entering a state of waiting for receiving server data, the receiving server analyzes the analysis data obtained according to the UICC data and stores the analysis data to the local, and enters a state of waiting for receiving data; and after entering a waiting data receiving state, selecting target analysis data meeting preset requirements from the analysis data and sending the target analysis data to the UICC. The terminal 102 may be, but not limited to, various personal computers, notebook computers, smart phones, tablet computers, and portable wearable devices, and the server 104 may be implemented by an independent server or a server cluster formed by a plurality of servers.
In an embodiment, as shown in fig. 2, a method for transmitting BIP protocol data is provided, which is described by taking the method as an example for being applied to the terminal in fig. 1, and includes the following steps:
The UICC (Universal Integrated Circuit Card) is an important link in the design of a 3GPP (3rd Generation Partnership Project) terminal, and is also a removable smart Card for storing information such as user information, an authentication key, a phone book, and a short message. The UICC includes, but is not limited to, a Subscriber Identity Module (SIM), a Universal Subscriber Identity Module (USIM), and an IP Multimedia Service Identity Module (ISIM). The command for opening the channel is a command for opening a BIP channel, and the BIP channel is a channel for establishing data connection between the UICC card and the service platform. Specifically, after receiving the service platform command, the UICC sends a channel opening command open channel command to the terminal, so that the terminal opens the BIP channel. The terminal is in an idle state at this time, where the idle state is that the terminal is used to wait for BIP channel establishment, that is, the terminal receives an open channel command.
And step 204, establishing connection with the server according to the channel opening command, and entering a data sending waiting state.
Here, the wait for data transmission state here is UICC data for allowing the terminal to wait for UICC transmission. Specifically, when the connection is established with the server according to the open channel command, the terminal and the server connection include, but are not limited to, a TCP (Transmission Control Protocol) connection and a UDP (User Datagram Protocol) connection, and the socket interface is an API interface function of the TCP/IP network. Therefore, after the terminal establishes socket communication with the server to transmit the transmission of data between the terminal and the server, a wait data transmission state is entered. The waiting data sending state is a state that the terminal waits for receiving the UICC data sent by the UICC.
And step 206, after entering a data transmission waiting state, acquiring a data transmission command sent by the UICC.
The data sending command is a command for receiving UICC data sent by the UICC, where the data sending command send data command includes, but is not limited to, a UICC data operation mode type and the like. Specifically, since the wait-for-data transmission state is a state for waiting for reception of UICC data transmitted by the UICC, after the terminal enters the wait-for-data transmission state, the terminal obtains a data transmission command transmitted by the UICC and notifies the terminal of the UICC data to be received.
And step 208, sending the UICC data acquired according to the data sending command to a server, and entering a state of waiting for receiving the server data.
The UICC data is related data corresponding to the UICC, including but not limited to SIM file data and the like. Specifically, after acquiring a data sending command sent by the UICC, the terminal stores the UICC data sent by the UICC to the terminal, and acquires the UICC data from the terminal according to the data sending command. Further, the acquired UICC data is sent to a server, and a state of waiting for receiving the server data is entered. Here, the server data waiting state is a state in which the terminal waits for UICC data to be sent by the UICC or sends the acquired UICC data to the server. That is, when the number of servers waiting for reception is the UICC data state for waiting for UICC transmission or the state for waiting for reception of server transmission data according to the state, the terminal switches to the next state after completing the UICC data state transmitted by the UICC or receiving the data transmitted by the server.
And step 210, after entering a state of waiting for receiving server data, receiving analysis data obtained by analyzing according to the UICC data by the server, storing the analysis data to the local, and entering a state of waiting for receiving data.
The analysis data is data obtained by analyzing the UICC data sent by the terminal by the server. Specifically, the data state is used by the terminal to wait for receiving the data sent by the server. Therefore, after entering a state of waiting for receiving server data, the receiving server analyzes the UICC data sent by the terminal to obtain analysis data, and stores the analysis data to the local terminal. After the terminal has finished receiving the analysis data sent by the server, the terminal switches the state and enters a data receiving waiting state from the data receiving waiting server state, wherein the data receiving waiting state is a state in which the terminal waits for receiving the data sent by the server or a state in which the terminal waits for sending the data to the UICC.
And step 212, after entering a data receiving waiting state, selecting target analysis data meeting preset requirements from the analysis data and sending the target analysis data to the UICC.
The UICC has a requirement specification for the length of the analysis data sent to the UICC by the terminal, so that the target analysis data is analysis data meeting the requirement selected from the analysis data sent from the server according to the preset required data length. Specifically, after the terminal enters a data receiving waiting state, because the terminal is in a state of waiting for sending data to the UICC, target analysis data meeting the requirement is selected from analysis data sent by the server according to the length requirement of the UICC on the analysis data sent by the terminal, and the target analysis data is sent to the UICC.
In the BIP protocol data transmission method, a terminal obtains a channel opening command sent by a terminal intelligent card UICC; establishing connection with a server according to a channel opening command, and entering a data sending waiting state; after entering a data sending waiting state, acquiring a data sending command sent by the UICC; sending the UICC data acquired according to the data sending command to a server, and entering a state of waiting for receiving the server data; after entering a state of waiting for receiving server data, the receiving server analyzes the analysis data obtained according to the UICC data and stores the analysis data to the local, and enters a state of waiting for receiving data; and after entering a waiting data receiving state, selecting target analysis data meeting preset requirements from the analysis data and sending the target analysis data to the UICC. Therefore, the terminal is limited to do certain events in a certain state, and the state switching can be performed after the specified events in the state are completed, so that the phenomenon that the BIP protocol data transmission between the terminal and the UICC and between the terminal and the server is interrupted because the terminal receives the data sent by the server and sends the event notification to the UICC card again every time is avoided.
In one embodiment, as shown in fig. 3, the method for BIP protocol data transmission further includes the following steps:
The data sending waiting state is a state in which the terminal is used for waiting for receiving UICC data sent by the UICC or receiving a close channel command sent by the UICC. Specifically, after target analysis data meeting the requirement of the UICC on the analysis data length is selected from the analysis data and sent to the UICC, whether all analysis data meeting the preset requirement are selected from the analysis data and sent to the UICC is detected, and when the condition that all analysis data meeting the preset requirement are selected from the analysis data is detected, the terminal is switched from a data waiting receiving state to a data waiting sending state.
And step 304, after entering a data transmission waiting state, acquiring a channel closing command sent by the UICC.
And step 306, disconnecting the server according to the channel closing command, and entering an idle state.
The command for closing the channel is a command for closing a BIP channel, where the BIP channel is a channel for establishing data connection between the UICC card and the service platform. Specifically, when the terminal is in a data transmission waiting state, the UICC sends a close channel command to the terminal after receiving a channel closing command from the service platform, so that the terminal obtains the channel closing command sent by the UICC to close the BIP channel. Further, the terminal disconnects the connection with the server according to the acquired channel closing command, and the terminal is switched to an idle state from a data transmission waiting state. The idle state here is a state in which the terminal is used to wait for the next BIP channel establishment, that is, to obtain the open channel command sent by the next UICC.
In one embodiment, as shown in fig. 4, the step of establishing a connection with the server according to the open channel command includes the steps of:
And step 404, establishing connection with the server through the PDP after the activation is successful.
The PDP is a network protocol used between the terminal and the server, and activating the PDP is equivalent to starting data flow between the server and the terminal. Specifically, after acquiring a channel opening command sent by the UICC, the terminal opens a BIP channel and activates a packet data protocol PDP according to the channel opening command. Further, after the successful PDP is activated according to the open channel command, since the PDP is a network protocol used between the terminal and the server, a communication connection is established with the server through the successfully activated PDP.
In an embodiment, as shown in fig. 5, the step of sending the UICC data obtained according to the data sending command to the server includes the following steps:
The data transmission command here includes, but is not limited to, UICC data operation mode type, etc. Specifically, an operation mode corresponding to the data sending command needs to be detected, and when the operation mode of the data sending command is detected to be a storage mode, the UICC data sent by the UICC is stored in a sending buffer of the terminal. Wherein, the sending buffer is used for storing data sent by the UICC to the terminal.
And step 508, sending the UICC data acquired from the sending buffer to a server.
Specifically, due to the limitation on the state of the terminal, after all UICC data sent by the UICC is stored in the sending buffer of the terminal, UICC data corresponding to the UICC needs to be obtained from the sending buffer of the terminal. Further, the UICC data acquired from the sending buffer of the terminal is sent to the server. That is, the terminal receives a data sending command from the UICC, and stores the data of the UICC sent by the UICC into a sending buffer of the terminal according to the operation mode of the data sending command. Further, all UICC data in the terminal's send buffer is sent to the server.
In an embodiment, as shown in fig. 6, the step of receiving the analysis data obtained by analyzing by the server according to the UICC data and storing the analysis data locally includes the following steps:
Specifically, after the terminal is in a state of waiting for receiving server data, the terminal sends the UICC data sent by all UICCs stored in the sending buffer to the server, and the server analyzes the UICC data sent by the receiving terminal to obtain analyzed data. The parsing data includes, but is not limited to, file information related to the UICC, and the like. Further, the server transmits the analysis data to a receiving buffer of the terminal, wherein the receiving buffer is used for storing the analysis data transmitted by the server. And the terminal stores the received analysis data sent by the server into a receiving buffer zone and sends an effective data event request to the UICC. The valid data event request is used to notify the UICC terminal that the parsed data sent by the server has been received, and after the UICC acquires the valid data event request sent by the terminal, the UICC can acquire the parsed data corresponding to the UICC data from the receive buffer of the terminal, and at this time, the terminal enters a wait data receive state from a wait to receive server send data state.
In an embodiment, as shown in fig. 7, the step of selecting target parsing data meeting the preset requirement from the parsing data and sending the target parsing data to the UICC includes the following steps:
Specifically, when the terminal is in a data receiving waiting state, the terminal stores the analysis data in a receiving buffer, sends an effective data event request to the UICC, notifies the UICC terminal that the analysis data sent by the server has been received, and sends a data receiving command to the terminal according to the effective data event request sent by the terminal. And the terminal receives a data receiving command from the UICC and analyzes data sent by the acquisition server stored in the local receiving buffer according to the data receiving command. Because the UICC requires length specification for the parsing data of the UICC sent by the terminal, the target parsing data meeting the requirement is selected from the parsing data according to the length requirement of the UICC for the parsing data sent by the terminal and sent to the UICC.
In an embodiment, as shown in fig. 8, a method for transmitting BIP protocol data is provided, which is described by taking the method as an example for being applied to the terminal in fig. 1, and includes the following steps:
and step 802, acquiring a channel opening command sent by the terminal intelligent card UICC.
Fig. 9 is a state diagram illustrating a method for BIP protocol data transmission in one embodiment. As shown in fig. 9, the terminal is in an idle state, where the idle state is a state in which the terminal waits for the BIP communication establishment, that is, obtains the open channel command sent by the UICC. Specifically, after receiving the service platform command, the UICC sends an open channel command to the terminal, so that the terminal obtains the open channel command sent by the UICC to open the BIP channel.
And step 804, activating the packet data protocol PDP according to the channel opening command.
As shown in fig. 9, the terminal activates the packet data protocol PDP according to the open channel command sent by the UICC, since the PDP is the network protocol used between the terminal and the server. So that socket communication can be established with the server by activating a successful PDP. Wherein, the terminal and the server establish socket communication connection because the terminal and the server connection include but are not limited to TCP, connection and UDP connection, and the socket interface is an API interface function of the TCP/IP network. After the socket communication connection is established between the terminal and the server, the terminal in the idle state enters a data sending waiting state.
Specifically, since the wait-to-send state is a state in which the terminal receives UICC data sent by the UICC. Therefore, after entering the data transmission waiting state, the terminal acquires a data transmission command sent by the UICC, and the data transmission command is used for informing the terminal of the UICC data to be received.
And step 812, storing the UICC data sent by the UICC to a send buffer when the operation mode is detected to be the storage mode.
As shown in fig. 9, when the terminal is in a data transmission waiting state, the terminal obtains a data transmission command sent by the UICC, and since the data transmission command carries an operation mode corresponding to the data transmission command, when it is detected that the operation mode of the data transmission command is a storage mode, the terminal stores UICC data sent by the UICC in a transmission buffer for storing the UICC data sent to the terminal. Further, the terminal sends the UICC data sent by all the UICCs in the sending buffer to the server. And after the terminal sends all the UICC data in the sending buffer to the server, the terminal is switched from the data sending waiting state to the server data receiving waiting state.
And step 820, storing the received analysis data to a receiving buffer, wherein the receiving buffer is used for storing the analysis data sent by the server.
As shown in fig. 9, after the terminal enters the server data waiting state, the server data waiting state is a state in which the terminal waits for the server to transmit data. Therefore, when the terminal is in a state of waiting for receiving the server data, the server analyzes the UICC data sent by the terminal to obtain the analysis data, and further, the terminal stores the received analysis data into a receiving buffer for storing the analysis data sent by the server to the terminal. And after storing the analysis data sent by all the servers in the receiving buffer zone, the terminal sends an effective data event request to the UICC. The UICC is configured to receive a request for an event of valid data from a server, where the request for the event of valid data is used to notify the UICC that the terminal has received the analysis data sent by the server, and after the UICC obtains the request for the event of valid data sent by the terminal, the UICC can obtain the analysis data corresponding to the UICC data from a receiving buffer of the terminal. And when the terminal sends a valid data event request to the UICC, the terminal is switched into a data waiting state from a data waiting state of the server to be received.
And step 826, acquiring the analysis data stored to the local according to the data receiving command.
And 828, selecting the analysis data meeting the preset requirement from the analysis data and sending the analysis data to the UICC.
As shown in fig. 9, after the terminal enters the data receiving waiting state, since the data receiving waiting state is a state in which the terminal is used to receive data, when the terminal is in the data receiving waiting state, after the terminal sends a valid data event request to the UICC to notify the UICC that the terminal has received the parsing data sent by the server, the UICC sends a data receiving command to the terminal, and the terminal receives the data receiving command sent by the UICC. Further, the terminal acquires the analysis data sent by the server from a receiving buffer area stored to the local part of the terminal according to the acquired data receiving command. And because the UICC requires length specification for the parsing data of the UICC sent by the terminal, the target parsing data meeting the requirement is selected from the obtained parsing data according to the length requirement of the UICC for the parsing data sent by the terminal and sent to the UICC. And when the terminal detects that the analysis data meeting the preset requirement is selected from the analysis data and sent to the UICC, the terminal is switched from the data receiving waiting state to the data sending waiting state.
Further, as shown in fig. 9, after it is detected that the selected parsing data meeting the preset requirement from the parsing data is completely sent to the UICC, the terminal may continue to receive the parsing data from the server, and thus the terminal continues to be maintained in a data receiving waiting state.
And 834, disconnecting the server according to the channel closing command, and entering an idle state.
As shown in fig. 9, when it is detected that the selection of the analysis data meeting the preset requirement from the analysis data is completed and the analysis data is sent to the UICC, the terminal returns to the state of waiting for data sending, and the UICC sends a close channel command to the terminal after receiving the command of the service platform to close the channel. And the terminal acquires a channel closing command sent by the UICC, disconnects the connection with the server and closes the BIP channel according to the channel closing command. And after the terminal disconnects the link with the server according to the channel closing command acquired from the UICC, the terminal is switched from the data sending waiting state to the idle state. The idle state at this time is a state in which the terminal is used to wait for the next BIP channel establishment, that is, the terminal obtains the open channel command sent by the next UICC.
In the above embodiment, by limiting the terminal to perform corresponding things independently in four states, the terminal can switch to the next state after completing the specified things in each state, and perform the corresponding things in the next state. The method not only effectively avoids that the terminal end receives the data re-sent event notification sent by the server to the UICC card every time, which causes the interruption of the BIP protocol data transmission between the terminal and the UICC and between the terminal and the server, but also can avoid the chaos of the BIP protocol data transmission between the terminal and the UICC and between the terminal and the server.
It should be understood that although the various steps in the flow charts of fig. 2-8 are shown in order as indicated by the arrows, the steps are not necessarily performed in order as indicated by the arrows.
