Detailed Description

In order to make the objects, technical solutions and advantages of the present invention clearer and clearer, the present invention is further described in detail below with reference to the accompanying drawings and examples. It should be understood that the specific embodiments described herein are merely illustrative of the invention and are not intended to limit the invention.

It should be noted that, if directional indications (such as up, down, left, right, front, and back … …) are involved in the embodiment of the present invention, the directional indications are only used to explain the relative positional relationship between the components, the movement situation, and the like in a specific posture (as shown in the drawing), and if the specific posture is changed, the directional indications are changed accordingly.

The intelligent terminal often has the phenomenon of no response when in use, for example, when a user needs to start a certain application program, the intelligent terminal does not respond to the starting operation of the user, namely, the starting fails. Which is basically related to the state information of the host. For example, when the board host is in a busy state (busy state), it cannot respond to the user's start request for starting the application; or when the host is in a crash state, the host cannot respond to the user's start request for starting the application. Researchers find that the state change of the host and the latest state of the host cannot be known in time in the prior art, so that the terminal equipment cannot establish communication with the host in time, the communication efficiency is influenced, and inconvenience is brought to the use of a user.

In order to solve the above problem, an embodiment of the present invention provides a method for acquiring a host status, where in the method, a terminal device in the embodiment of the present invention first sends application start request information to a host, where the application start request information is used to access a host corresponding to a preset application program, and therefore the terminal device in this embodiment may actively send the application start request information when starting a certain preset application program, so that the host feeds back its own status information according to a start status of the preset application program. Specifically, after the host receives the application start request information, the host responds to the application start request information and sends byte code value information to the terminal device, and the terminal device may obtain a first state type identifier according to the byte code value information, where the first state type identifier is used to reflect a state type of the host when the host responds to the application start request information. Then, the host sends state change information to the terminal device when the state changes, and the terminal device can obtain a second state type identifier according to the state change information, wherein the second state type identifier is used for reflecting the state type of the host after the state changes. Therefore, the terminal device determines the changed state of the host according to the state type identifier and the second state type identifier. In other words, the terminal device can obtain which or which state the host has changed according to the state type of the host when responding to the application start request information and the state type obtained after the host has occurred, so as to timely know the latest state of the host, facilitate the terminal device to timely establish communication with the host after the host is abnormally recovered, realize data interaction, improve communication efficiency, and provide convenience for users.

For example, when the terminal device starts the wechat program, the application start request information is sent to the host corresponding to the wechat program. The host receives the application starting request information, responds to the application starting request information, and then sends byte code value information to the terminal equipment according to the starting state of the WeChat program. And after receiving the byte code value information, the terminal equipment obtains a first state type identifier according to the byte code value information, and if the obtained first state type identifier is Start OK, Link 4 and Busy. Wherein, Start OK represents that the starting state of the host computer is successful; link 4 indicates that the communication connection state of the host is to connect 4 applications (that is, 4 applications communicate with the same application); busy indicates that the running state of the host is Busy at this time. At this time, the terminal device acquires each state type of the host in response to the application start request information. Then, when the busy state of the host changes to an idle state (i.e., the host has changed state), state change information including the second type identifier is sent to the terminal device, and at this time, the second type identifier is Start OK, Link 4, and Free. Therefore, by using the first type identifier and the second type identifier, it can be known that the state that the host has changed is the running state of the host, i.e. the running state is changed from Busy state to Free state. Therefore, the terminal equipment can timely know the state information of the host machine so as to timely establish communication with the host machine and realize data interaction.

Exemplary method

The invention provides a host state acquisition method which can be applied to a host state acquisition system, wherein the host state acquisition system comprises terminal equipment and a host which is in communication connection with the terminal equipment. Therefore, the host state acquisition method can be applied to both terminal equipment and the host. Specifically, in one embodiment, as shown in FIG. 1, the method comprises the steps of:

step S1, the terminal device sends application start request information to the host.

In this embodiment, the host in this embodiment refers to any computer device connected with an Internet device in a TCP/IP protocol, and similarly to a server, an application program of a terminal device may be in communication connection with the host. Therefore, when the terminal device starts a preset application program, the terminal device sends application start request information to the host corresponding to the preset application program so as to access the host corresponding to the application program, so as to acquire the state of the host. In this embodiment, the application start request information is information sent to a host corresponding to a preset application program when the terminal device starts the preset application program, and the application start request information is used to access the host corresponding to the application program to acquire a state of the host. For example, in the above example, when the terminal device starts the wechat program, the terminal device sends the application start request information to the host corresponding to the wechat program.

Step S2, the host responds to the application start request information, and feeds back byte code value information to the terminal device.

In this embodiment, the host responds to the application start request information, first obtains a start state of a preset application program in the terminal device, then obtains a self state according to the start state of the preset application program, generates the bytecode value information, and sends the bytecode value information to the terminal device. For example, in the above example, if the start of the wechat program in the terminal device fails, the host acquires the state of the host at that time, generates the bytecode value information, and sends the bytecode value information to the terminal device.

Step S3, the terminal device receives the byte code value information, and acquires the first state type identifier from the byte code value information.

In this embodiment, the byte code value information is code value information generated when the host responds to the application start request information, and the application start request information is sent to the host when the terminal device starts a preset application program, so that the byte code value information is used for reflecting a state of the terminal device when the preset application program is started. And after the terminal equipment receives the byte code value information, obtaining the first type identification according to the byte code value information, wherein the first type identification can reflect the state type of the host when the terminal equipment starts a preset application program. The first state type identifier may be in the form of a code or a character. For example, in the above example, after receiving the byte code value information, the terminal device obtains the first state type identifiers Start OK, Link 4, and Busy according to the byte code value information. Wherein, Start OK represents that the starting state of the host computer is successful; link 4 indicates that the communication connection state of the host is to connect 4 applications (that is, 4 applications communicate with the same application); busy indicates that the running state of the host is Busy at this time.

Step S4, the host sends status change information to the terminal device when a status change occurs.

In this embodiment, in order to timely know whether the state of the host changes and timely acquire the latest state of the host, the host in this embodiment may acquire its own state again when the state changes, generate state change information, and send the state change information to the terminal device. A state change is a change in a state of a host. In one embodiment, the state change information may also be information consisting of various types of characters (i.e., changing from one state to another). As described above, for example, when the operating state of the host changes, the state change information is generated and sent to the terminal device.

Step S5, the terminal device receives the state change information, and obtains a second type identifier from the state change information.

In this embodiment, the state change information is generated when the host changes the state, and the state change information represents the state of the host after the state change. And after receiving the state change information, the terminal device obtains the second type identifier from the state change information, wherein the second state type identifier is used for reflecting the state type of the host after the state change occurs, and the second state type identifier can be in a code form or a character form. For example, in the above example, after receiving the state change information, the terminal device extracts the second state type identifiers Start OK, Link 4, and Free from the state change information. Free indicates that the operating state of the host is idle at this time.

Step S6, the terminal device determines the changed state of the host according to the first state type identifier and the second state type identifier.

In this embodiment, since the terminal device has already acquired the first state type identifier and the second state type identifier, and the first state type identifier is used to reflect a state type of the host when responding to the application start request information; the second state type identification is used for reflecting the state type of the host after the state change; therefore, by comparing the first state type identifier with the second state type identifier, the changed state of the host can be known, so that the latest state of the host can be known in time, and the communication connection with the host can be established in time to realize data interaction. As in the example above, the first state type is identified: start OK, Link 4 as Busy; comparing with the second state type identifiers of Start OK, Link 4 and Free, the state identifier corresponding to the running state of the host is found to be changed from Busy to Free, so that the running state of the host can be determined to be changed from Busy to idle.

In another embodiment, as shown in fig. 2, when the host status acquiring method is applied to a terminal device, the method includes the following steps:

step S10, the terminal device sends application start request information to the host, where the application start request information is used to access the host corresponding to the preset application program to obtain the state of the host.

In this embodiment, many processes of the terminal device are associated with the state of the host, so to ensure stable operation of the terminal device and smooth communication with the host, when the terminal device starts a preset application program, the terminal device sends application start request information to the host corresponding to the preset application program to access the host corresponding to the application program, so as to obtain the state of the host. This step has already been described above and will not be described again here.

Step S20, the terminal device receives the bytecode value information fed back by the host in response to the application start request information, so as to obtain a first state type identifier according to the bytecode information, where the first state type identifier is used to reflect a state type of the host in response to the application start request information.

In this embodiment, the host may respond to the application start request information, acquire the start state of the application program preset in the terminal device, then acquire the state of the host according to the start state of the preset application program, generate the bytecode value information, and send the bytecode value information to the terminal device. And after receiving the byte code value information, the terminal equipment acquires the first state type identifier from the byte code value information, and can obtain the state type of the host when responding to the application starting request information according to the first state type identifier.

In one embodiment, as shown in fig. 3, the step S20 includes the following steps:

step S201, receiving the byte code value information which is generated by the host in response to the application starting request and is used for reflecting the state information of the host;

step S202, determining state information of the host and the first state type identifier corresponding to the state information according to the byte code value information, wherein the state information is used for indicating a state type when the host responds to the application starting request.

In this embodiment, after receiving the byte code value information sent by the host, the terminal device analyzes the byte code value information, and determines the state information of the host and the first state type identifier corresponding to the state information according to the byte code value information. In one embodiment, since the host is in different states, different byte code value information is generated, and the byte code value information includes various types of data, in addition to the data for reflecting the first state type identifier, other data, such as time data for acquiring the byte code value information. In order to accurately know the first state type identifier reflected by the byte code value information after receiving the byte code value information fed back by the host, a mapping relationship table is preset in this embodiment, and the mapping relationship table stores the corresponding relationship between the byte code value information and the state information. For example, the preset byte code value information 0x01 corresponds to the startup state information of the host; setting byte code value information 0x02 corresponding to connection state information of the host; the set byte code value information 0x03 corresponds to the operation state information of the host. Therefore, after the byte code value information is acquired, the byte code value information is matched with the mapping relation table to obtain the state information contained in the byte code value information. That is, in this embodiment, the purpose of matching the byte code value information with the mapping relationship table is to determine which states of the host are reflected in the byte code value information.

In a further implementation manner, after the state information is obtained, the first state type identifier corresponding to the state information is further obtained in this embodiment. Specifically, in this embodiment, status query information may be sent to the host according to the status information, the host responds to the status query information after receiving the status query information to generate status type response information, and the terminal device acquires the first status type identifier from the status type response information after receiving the status type response information. That is to say, the status query information in this embodiment is information sent by the terminal device to the host, and the status query information is used to obtain the first status type identifier corresponding to the status information. In addition, since the plurality of state information in this embodiment includes the startup state information of the host, the operation state information of the host, the connection state information of the host, and the like, different state inquiry information is sent to the host according to different state information, and thus the state type response information fed back by the host is also different. The state type response message is sent by the host to the terminal device and is used for responding to the state inquiry message, so that the state type response message contains the first state type identifier. In this embodiment, the corresponding state identifier is obtained from each state type response message, and then all the obtained state identifiers form the first state type identifier.

For example, as shown in fig. 6, fig. 6 shows an embodiment of the present invention, specifically, an interaction between a CICAM card (i.e. a network smart card in a terminal device) and a Host (Host). When the CICAM card sends application start request information to the Host through RequestStart (), the Host responds to the application start request information after receiving the application start request information and replies to the CICAM card through RequestStartAck (AckCode), and at this time, RequestStartAck (AckCode) replied by the Host is byte code value information, because different AckCode values represent different state information, and the corresponding relationship between the AckCode values and the state information is defined in the specification ETSI TS 103205 V1.1.1(2014-03) (a specification protocol, which is equivalent to the preset mapping relationship table) of CIPLlus 1.4. If the AckCode received in fig. 6 is 0x03, the corresponding status information is the operating status information of the host. Further, after receiving the AckCode value of 0x03, the CICAM card sends GetBusy (i.e. sends status query information to the Host according to the status information) to query the Host to obtain the first status type identifier, and the Host may generate status type response information getbyack (busy type value) and return status type response information getbyack (busy type value) to the CICAM card, and the CICAM card may obtain busy type value (equivalent to the first status type identifier) from the status type response information getbyack (busy type value). As can be seen from the next time, in this embodiment, the state information of the host and the corresponding first state type identifier may be acquired through interaction between the terminal device and the host. In the same way, the AckCode value sent by the terminal device represents different state information, and then different state inquiry information is sent to the host according to the different state information, so that the state type response information fed back by the host is also different, different state identifiers are obtained, and then all the state identifiers form the first state type identifier.

As an example, the first status type identifier obtained by the above steps may be StartOK, Link 4, and Busy. Wherein, Start OK represents that the starting state of the host computer is successful; link 4 indicates that the communication connection state of the host is to connect 4 applications (that is, 4 applications communicate with the same application); busy indicates that the running state of the host is Busy at this time.

Further, in step S30, the terminal device receives the status change information sent by the host when the status change occurs, where the status change information includes a second status type identifier, and the second status type identifier is used to reflect the status type of the host after the status change occurs.

In this embodiment, in order to timely know whether the state of the host changes and timely acquire the latest state of the host, the host in this embodiment may acquire its own state again when the state changes, generate state change information, and send the state change information to the terminal device. And after receiving the state change information, the terminal equipment obtains the second type identifier from the state change information, wherein the second type identifier is used for reflecting the state type of the host after the state change occurs. For the acquisition of the second state type identifier, the second state type identifier may be actively acquired by the terminal device to the host, or may be actively sent by the host to the intelligent terminal. For example, the terminal device in this embodiment may set a polling program, where the polling program may send an inquiry request to the host at preset time intervals, send state change information to the terminal device through a response of the host to the inquiry request, and enable the terminal device to acquire the second state type identifier from the state change information. Or, in this embodiment, after the state change occurs, the host may actively send state change information to the terminal device, so that the terminal device obtains the second state type identifier from the state change information.

In one embodiment, the step S30 is specifically shown in fig. 4, and includes the following steps:

step S301, receiving the state change information sent by the host, where the state change information is generated when the state of the host changes, and the state change information includes a second state type identifier used for reflecting a state type of the host after the state change and corresponding to the state type;

step S302, parsing the state change information, and extracting the second state type identifier from the state change information.

In this embodiment, when the state of the host changes, a state change message is generated and sent to the terminal device. Since the state change information is generated when the state of the host changes, the state change information includes a second state type identifier for reflecting the state type of the host after the state change and the state type. In this embodiment, the terminal device may parse the state change information after receiving the state change information, and then extract the second state type identifier from the state change information. In order to immediately generate the state change information when the state of the host changes in time, a monitor can be provided in this embodiment, and the monitor is utilized to monitor the state of the host in real time, so as to know whether the state of the host changes in time.

For example, as shown in fig. 6, the Host actively generates status change information busy request (busy type value) when a status change occurs, and then sends the busy request (busy type value) to the CICAM card, and the CICAM card can extract the busy type value (which is equivalent to the second status type identifier) from the status change information busy request (busy type value).

As in the above example, the last obtained second status type identifier may be Start OK, Link 4, and Free. Free indicates that the operating state of the host is idle at this time.

Further, in step S40, the terminal device determines the changed state of the host according to the first state type identifier and the second state type identifier.

The intelligent terminal acquires the first state type identifier and the second state type identifier, and the first state type identifier is used for reflecting the state type of the host when the host responds to the application starting request information; the second state type identification is used for reflecting the state type of the host after the state change, so that the first state type identification is compared with the second state type identification, the changed state of the host can be known, the latest state of the host can be known in time, the terminal equipment can conveniently and timely establish communication with the host after the abnormal recovery of the host, the communication efficiency is improved, the data interaction is realized, and convenience is brought to the use of a user.

In one embodiment, as shown in fig. 5, the step S40 includes the following steps:

step S401, comparing the first state type identifier with the state identifiers corresponding to the same state information in the second state type identifier one by one to obtain comparison results;

step S402, determining the state identifier corresponding to the same state information and different from the first state type identifier and the second state type identifier according to the comparison result;

step S403, determining the changed state of the host according to the different state identifiers.

Specifically, first state type sign with second state type sign all includes a plurality of state signs, in order to determine more swiftly the state that the host computer has changed, in this embodiment will respectively first state type sign with the sign of corresponding same status information in the second state type sign carries out the contrast one by one, can know more directly perceivedly like this first state type sign with which the status sign that corresponds same status information of second state type sign is inequality, has determined to correspond the different status sign of same status information, then can know the state that the host computer has changed.

For example, if the obtained first status type is identified as Start OK, Link 4, and Busy. The obtained second state type identifiers are Start OK, Link 4 and Free, wherein the Start OK represents that the starting state of the host is successful; link 4 indicates that the communication connection state of the host is to connect 4 applications (that is, 4 applications communicate with the same application); busy indicates that the running state of the host is a Busy state at the moment, and Free indicates that the running state of the host is an idle state at the moment. Therefore, comparing the first status type identifier with the status identifier corresponding to the same status information in the second status type identifier one by one, if the Start OK in the first status type identifier is the same as the Start OK in the second status type identifier; link 4 in the first state type identifier is the same as Link 4 in the second state type identifier; the Busy information of the host is stored in the first state type identifier, the Busy information of the host is stored in the second state type identifier, and the Busy information of the host is stored in the second state type identifier.

In another embodiment, as shown in fig. 7, when the host status acquiring method is applied to a host, the host refers to any computer device connected with an Internet device in TCP/IP protocol, and the method includes the following steps similar to a server:

step S100, the host receives application starting request information sent by the terminal device, and the application starting information is used for accessing the host corresponding to a preset application program so as to acquire the state of the host.

In this embodiment, many processes of the terminal device are associated with the state of the host, so to ensure stable operation of the terminal device and smooth communication with the host, when the terminal device starts a preset application program, the terminal device sends application start request information to the host corresponding to the preset application program, and the host receives the application start request information sent by the terminal device and responds to the application start request information. This step has already been described above and will not be described again here.

Step S200, the host generates byte code value information according to the application starting request information, and sends the byte code value information to the terminal equipment, so that the terminal equipment obtains a first state type identifier according to the byte code value information, wherein the first state type identifier is used for reflecting the state type of the host when the host responds to the application starting request information.

In this embodiment, after receiving the application start request information, the host responds to the application start request information, acquires a start state of a preset application program in the terminal device, then acquires a state of the host according to the start state of the preset application program, generates the bytecode code value information, and sends the bytecode code value information to the terminal device, so that the terminal device acquires the first state type identifier from the bytecode code value information after receiving the bytecode code value information, and can obtain a state type of the host when responding to the application start request information according to the first state type identifier.

In one embodiment, as shown in fig. 8, the step S200 includes:

step S210, accessing a preset application program according to the application starting request information;

step S220, generating byte code value information for reflecting the state information of the host according to the starting state of the application program; the bytecode information is used for determining state information of the host and a first state type identifier corresponding to the state information, and the state information is used for representing a state type when the host responds to the application starting request;

and step S230, sending the byte code value information to the terminal equipment.

Specifically, after receiving the application start request information, the host accesses a preset application program according to the application start request information, and since the preset application program corresponds to the host, the accessed preset application program is also an application program corresponding to the host, such as the wechat program in the above example. And then the host acquires the starting state of the application program, generates byte code value information for reflecting the state information of the host according to the starting state of the application program, and sends the byte code value information to the terminal equipment. And after receiving the byte code value information sent by the host, the terminal equipment analyzes the byte code value information, and determines the state information of the host and the first state type identifier corresponding to the state information according to the byte code value information. In one embodiment, since the host is in different states, different byte code value information is generated, and the byte code value information includes various types of data, in addition to the data for reflecting the first state type identifier, other data, such as time data for acquiring the byte code value information. In order to accurately know the first state type identifier reflected by the byte code value information after receiving the byte code value information fed back by the host, a mapping relationship table is preset in this embodiment, and the mapping relationship table stores the corresponding relationship between the byte code value information and the state information. For example, the preset byte code value information 0x01 corresponds to the startup state information of the host; setting byte code value information 0x02 corresponding to connection state information of the host; the set byte code value information 0x03 corresponds to the operation state information of the host. Therefore, after the byte code value information is acquired, the byte code value information is matched with the mapping relation table to obtain the state information contained in the byte code value information. That is, in this embodiment, the purpose of matching the byte code value information with the mapping relationship table is to determine which states of the host are reflected in the byte code value information.

In a further implementation manner, after the terminal device of this embodiment acquires the state information, the terminal device further acquires a first state type identifier corresponding to the state information. Specifically, in this embodiment, status query information may be sent to the host according to the status information, the host responds to the status query information after receiving the status query information to generate status type response information, and the terminal device acquires the first status type identifier from the status type response information after receiving the status type response information. That is to say, the status query information in this embodiment is used to obtain the first status type identifier corresponding to the status information. In addition, since the plurality of state information in this embodiment includes the startup state information of the host, the operation state information of the host, the connection state information of the host, and the like, different state inquiry information is sent to the host according to different state information, and thus the state type response information fed back by the host is also different. In this embodiment, the corresponding state identifier is obtained from each state type response message, and then all the obtained state identifiers form the first state type identifier.

Further, in step S300, when a state change occurs in the host, the host sends state change information to the terminal device, where the state change information includes a second state type identifier, and the second state type identifier is used to reflect a state type of the host after the state change occurs, so that the terminal device determines the changed state of the host according to the first state type identifier and the second state type identifier.

In this embodiment, in order to timely know whether the state of the host changes and timely acquire the latest state of the host, the host in this embodiment may acquire its own state again when the state changes, generate state change information, and send the state change information to the terminal device. Because the state change information includes the second state type identifier, after the terminal device receives the state change information, the second state type identifier is obtained from the state change information, and the second state type identifier is used for reflecting the state type of the host after the state change occurs. For the acquisition of the second state type identifier, the second state type identifier may be actively acquired by the terminal device to the host, or may be actively sent by the host to the intelligent terminal. For example, the terminal device in this embodiment may set a polling program, where the polling program may send an inquiry request to the host at preset time intervals, send state change information to the terminal device through a response of the host to the inquiry request, and enable the terminal device to acquire the second state type identifier from the state change information. Or, in this embodiment, after the state change occurs, the host may actively send state change information to the terminal device, so that the terminal device obtains the second state type identifier from the state change information.

In one embodiment, as shown in fig. 9, the step S300 includes:

step S310, when the state change of the host is monitored, state change information is generated, wherein the state change information comprises a state type used for reflecting the state change of the host and a second state type identifier corresponding to the state type;

step S320, sending the state change information to the terminal device, so that the terminal device determines the changed state of the host according to the first state type identifier and the second state type identifier.

For example, as shown in fig. 6, the Host actively generates status change information Busy Release Request (Busy type value) when a status change occurs, and then sends the Busy Release Request (Busy type value) to the CICAM card, and the CICAM card can extract the Busy type value (corresponding to the second status type identifier in this case) from the status change information Busy Release Request (Busy type value).

Further, the intelligent terminal obtains the first state type identifier and the second state type identifier, and the first state type identifier is used for reflecting the state type of the host when responding to the application starting request information; the second state type identification is used for reflecting the state type of the host after the state change, so that the first state type identification is compared with the second state type identification, the changed state of the host can be known, the latest state of the host can be known in time, the terminal equipment can conveniently and timely establish communication with the host after the abnormal recovery of the host, the communication efficiency is improved, the data interaction is realized, and convenience is brought to the use of a user.

In summary, in the embodiment of the present invention, the terminal device first sends the application start request information to the host, where the application start request information is used to access the host corresponding to the preset application program, and therefore the terminal device of this embodiment actively sends the application start request information when starting a certain preset application program. After the host receives the application start request information, the host responds to the application start request information and sends byte code value information to the terminal equipment according to the start state of a preset application program, and the terminal equipment can obtain a first state type identifier according to the byte code value information, wherein the first state type identifier is used for reflecting the state type of the host when the host responds to the application start request information. Then, the host sends state change information to the terminal device when the state changes, and the terminal device can obtain a second state type identifier according to the state change information, wherein the second state type identifier is used for reflecting the state type of the host after the state changes. Therefore, the terminal device determines the changed state of the host according to the state type identifier and the second state type identifier. In other words, the terminal device can obtain which or which state the host has changed according to the state type of the host when responding to the application start request information and the state type obtained after the host has occurred, so as to timely know the latest state of the host, facilitate the terminal device to timely establish communication with the host after the host is abnormally recovered, improve communication efficiency, realize data interaction, and provide convenience for users to use.
