Throughout the drawings, it should be noted that like reference numbers are used to depict the same or similar elements, features, and structures.
The following description with reference to the accompanying drawings is provided to assist in a comprehensive understanding of various embodiments of the present disclosure as defined by the claims and their equivalents. It includes various specific details to assist in that understanding but these are to be regarded as merely exemplary. Accordingly, those of ordinary skill in the art will recognize that various changes and modifications of the various embodiments described herein can be made without departing from the scope and spirit of the present disclosure. In addition, descriptions of well-known functions and constructions may be omitted for clarity and conciseness.
The terms and words used in the following description and claims are not limited to the bibliographical meanings, but, are merely used by the inventor to enable a clear and consistent understanding of the present disclosure. Accordingly, it should be apparent to those skilled in the art that the following description of various embodiments of the present disclosure is provided for illustration purpose only and not for the purpose of limiting the present disclosure as defined by the appended claims and their equivalents.
It is to be understood that the singular forms “a,” “an,” and “the” include plural referents unless the context clearly dictates otherwise. Thus, for example, reference to “a component surface” includes reference to one or more of such surfaces.
The information transmitting system includes an electronic device 100 and a push platform 200 that provides a push service. The electronic device 100 may include not only Information Technology (IT) devices such as a smart phone, a tablet Personal Computer (PC), a computer, a notebook and the like but also home appliances such as a Television (TV), a refrigerator, and a vacuum cleaner. The push platform 200 may include a push server 201, a provisioning server 202, and an administrator server (admin server) 203.
The present disclosure is applied to a push service based on a network. The push service aims at transmitting a particular message or notification to the electronic device. The push service begins with limited resources of the electronic device 100. When the push service is used, a plurality of applications executed in the electronic device 100 maintains only one common network connectivity instead of respective network connectivities and supports transmission of a message or notification to each of the applications in a side of a mobile platform, so that limits due to the limited resources can be somewhat overcome and various services can be used. The service uses push techniques such as Apple Push Notification Service (APNS) of Apple, Android Cloud to Device Messaging (C2DM) and Google Cloud Messaging (GCM) of Google, BlackBerry Push Notification Service (BPNS) of Blackberry, Samsung Push Platform (SPP) of Samsung or the like.
In general, the electronic device 100 and the push platform 200 should be logically connected to each other for the push service. User Datagram Protocol (UDP)/Transmission Control Protocol (TCP) can be used for the connection between the electronic device 100 and the push platform 200, and the push platform 200 and each electronic device 100 exchange a keep-alive message to maintain the connection there between.
At this time, a transmission period of the keep-alive message is dependent on a firewall timeout policy of a communication service provider and there is no universal convention or standard.
In order to continuously keep a push channel, an always-on connection of the electronic device 100 should be guaranteed. In a method of maintaining the always-on connection, the electronic device 100 transmits a keep-alive message such as heartbeat or ping message to a server before a firewall timeout to extend a timeout time of the channel.
The information transmitting system according to the embodiment of the present disclosure may simultaneously transmit information at a time when the electronic device 100 transmits the keep-alive message to the push platform 200, for example, the push server 201 in order to maintain the push channel. The push server 201 may receive log information transmitted from the electronic device 100. The information refers to log information which records a use state, a processed content or the like of information used by the user. For example, the log information may include a use state and/or a processed content of an application stored in the electronic device, and a state and/or a processed content about the use of peripheral devices such as a sensor, a camera, and an audio device included in the electronic device 100. For example, the log information may include a use state and/or a processed content of a peripheral device included in the electronic device 100, an application included in the electronic device 100, and an application program included in the electronic device 100.
The provisioning server 202 may transmit setting information used for transmitting the log information and information on a version of the corresponding setting information to the electronic device 100. The setting information may include log information collection setting value information for collecting log information such as an address of the push server to which one or more electronic devices 100 will transmit collected log information. The log information collection setting value information includes setting values used for collecting log information, such as a limited number of transmissions at one time, a limited number of transmissions of an application, a log information collection period, and a model name of an electronic device or an application name which is restricted from collecting log information.
The provisioning server 202 transmits information on a version of the corresponding setting information to the electronic device 100 together with the setting information. The electronic device 100 compares the version of the setting information received from the provisioning server 202 with a pre-stored version of setting information. When there is a difference between the versions, the electronic device 100 updates the setting information received from the provisioning server 202.
The admin server 203 may update the setting information according to the information on the version of the setting information and the version of the setting information. The admin server 203 transmits the changed setting information and the changed information of the version of the setting information to all push servers 201 and the provisioning server 202. The electronic device 100 may transmit collected log information to the push server 201, and may transmit the changed information on the version of the setting information when transmitting a response message of the keep-alive message to the push server 201. The electronic device 100 receives the changed information on the version of the setting information. When there is a difference between the received version and a pre-stored version of setting information, the electronic device 100 may receive changed setting information from the provisioning server 202. The admin server 203 may make a request for a particular operation command to the push server 201. The push server 201 may make a request for the push to the electronic device 100 in response to the particular operation command of the admin server 203. The electronic device 100 may perform a particular operation according to the push request and transmit a result of the particular operation to the push server 201. The particular operation command may include a command to start collecting one or more pieces of log information, a command to stop collecting log information, a command to collect emergency log information, a command to stop collecting emergency log information, or a provision command. The command to start collecting log information may instruct the electronic device 100 to start collecting log information according to a keep-alive period and the command to stop collecting log information instructs the electronic device 100 to stop collecting log information which has been collected according to a keep-alive period. The command to collect emergency log information instructs the electronic device 100 to start collecting log information regardless of a keep-alive period and the command to stop collecting emergency log information instructs the electronic device 100 to stop collecting log information which has been collected by the command to start collecting emergency log information. The provision command instructs the electronic device 100 to immediately receive changed setting information from the provisioning server 202.

The provisioning server 202 transmits setting information and information on a version of the setting information to the electronic device 100 in operation 301. The electronic device 100 stores the setting information and the information on the version of the setting information received from the provisioning server 202. The setting information may include log information collection setting value information for collecting log information such as an address of the push server to which one or more electronic devices 100 will transmit collected log information. The log information collection setting value information may include setting values used for collecting log information, such as a limited number of transmissions of log information at one time, a limited number of transmissions of log information in one day, a limited number of transmissions of log information for each application, a log information collection period, a model name or an application name which is restricted from collecting log information. The information on the version of the setting information may inform of information on the content of the changed setting information. For example, in the information on the version of the setting information, a number of times by which the setting information is changed may be indicated by a number. For example, the electronic device 100 transmits a keep-alive message and/or log information according to an address of the push server 201 included in the setting information. The electronic device 100 may identify a version of the collected log information of the electronic device 100 according to the information on the version of the setting information and may identify a list of log information to be collected according to the log information collection setting value information included in the setting information. The electronic device 100 collects log information of the electronic device 100 according to the setting information in operation 303. The electronic device 100 generates a keep-alive message to maintain a push channel in operation 305. The electronic device 100 transmits the keep-alive message and the log information to the push server 201 in operation 307. For example, the electronic device 100 transmits the log information at a time when the electronic device 100 transmits the keep-alive message to the push server 201 in operation 307. The electronic device 100 may transmit the log information to the push server 201 in the form of Hypertext Transfer Protocol Secure (HTTPS)/Transmission Control Protocol (TCP) in operation 307.
The electronic device 100 receives setting information and information on a version of the setting information received from the provisioning server 202 in operation 401. The electronic device 100 may receive the setting information and the information on the version of the setting information and store the received information in the storage unit 140, and the controller 170 may control log information and a push service by using the stored setting information. For example, the electronic device 100 may transmit a keep-alive message and/or log information to the push server 201 according to a keep-alive message transmission period included in the setting information. At this time, the transmission period may be included in the setting information transmitted from the provisioning server 202 or may be internally configured by the electronic device 100.
The electronic device 100 collects log information in operation 403. For example, the log information may include a use state and/or a processed content of an application stored in the electronic device, and a state and/or a processed content about the use of peripheral devices such as a sensor, a camera, and an audio device included in the electronic device 100. For example, the log information may include a use state and/or a processed content of a peripheral device included in the electronic device 100, an application included in the electronic device 100, and an application program included in the electronic device 100. The electronic device 100 may identify a version of collected log information before transmitting the log information to the push server 201 (for example, before updating the log information) according to log information collection setting value information included in the setting information. The electronic device 100 may collect log information by identifying a target to be collected according to the log information collection setting value information included in the setting information. The collected log information may be stored in the storage unit 140 under a control of the controller 170.
The electronic device 100 determines whether a preset transmission period arrives in operation 405. The transmission period may be transmitted from the outside of the electronic device 100 or internally configured by the electronic device 100. The electronic device 100 determines whether a transmission period when the keep-alive message for maintaining a push channel is transmitted to the push server 201 arrives in operation 405. When the preset transmission period does not arrive, for example, when the transmission period when the keep-alive message for maintaining the push channel is transmitted to the push server 201 does not arrive, the electronic device 100 continuously collects log information.
When the preset transmission period arrives, for example, the transmission period when the keep-alive message for maintaining the push channel is transmitted to the push server 201 arrives, the electronic device 100 generates the keep-alive message in operation 407.
When the keep-alive message for maintaining the push channel is generated, the electronic device 100 may transmit the keep-alive message and collected log information to the push server 201 in operation 409. For example, the electronic device 100 may transmit log information, which is collected at the time when the keep-alive message for maintaining the push channel is transmitted, to the push server 201 in operation 409.
The provisioning server 202 transmits setting information and information on a version of the setting information to the electronic device 100 in operation 501. The setting information may include log information collection setting value information for collecting log information such as an address of the push server to which the electronic devices 100 will transmit collected log information. The log information collection setting value information may include setting values used for collecting log information, such as a limited number of transmissions of log information at one time, a limited number of transmissions of log information in one day, a limited number of transmissions of log information for each application, a log information collection period, and a model name or an application name which is restricted from collecting log information. For example, the electronic device 100 transmits a keep-alive message and/or log information according to an address of the push server 201 included in the setting information. The electronic device 100 may identify whether the setting information is used to be updated according to the version of the setting information. For example, the electronic device 100 compares information on versions of the setting information and thus can compare the content of the setting information included in a previous version with the content of the latest setting information. When the changed information on the version of the setting information transmitted from the push server 201 is different from the pre-stored information on the version of the setting information through a comparison there between, the electronic device 100 may receive the changed setting information from the provisioning server 202.
The electronic device 100 collects log information of the electronic device 100 according to the setting information in operation 503. The electronic device 100 generates a keep-alive message to maintain a push channel in operation 505.
The admin server 203 may change the setting information and the version of the setting information in operation 507. For example, the admin server 203 may change the setting information in operation 507. The changeable setting information may include the content, type, and a collection method of log information to be collected when the electronic device 100 collects the log information. When the number of electronic devices 100 is plural, the content, type, and a collection method of log information of a plurality of electronic devices 100 in a particular region may be changed. The admin server 203 may assign a new version to the changed setting information in operation 509. The admin server 203 may transmit the changed setting information and the changed information on the version of the setting information to the provisioning server 202 and the push server 201 in operation 511. In another embodiment of the present disclosure, the admin server 207 may change the setting information and the information on the version of the setting information in operation 507 and transmit the changed setting information and the changed information on the version of the setting information, and the electronic device 100 may receive the changed setting information and the changed information on the version of the setting information.
The provisioning server 202 stores the changed setting information (for example, a changed log information collection setting value information version) received from the admin server 203 in operation 513. The provisioning server 202 may store the changed setting information (for example, changed log information collection setting value information) received from the admin server 203 instead of the previously stored setting information in operation 513.
The push server 201 may store the changed version of the setting information in operation 515. The push server 201 may cache the changed version of the setting information in operation 515.
The electronic device 100 transmits the keep-alive message and the log information to the push server 201 in operation 517. For example, the electronic device 100 transmits the log information at a time when the electronic device 100 transmits the keep-alive message to the push server 201 in operation 517. The electronic device 100 may transmit the log information to the push server 201 in the form of HTTPS/TCP in operation 517.
The push server 201 generates a keep-alive response message in operation 519. For example, when the push server 201 receives the keep-alive message and/or the log information from the electronic device 100, the push server 201 generates the keep-alive response message to be transmitted to the electronic device 100 in response to the keep-alive message and/or the log information in operation 519. The push server 201 may transmit the keep-alive response message and information on the version of the changed setting information which is stored (for example, which is cached) to the electronic device 100 in operation 521. For example, the push server 201 may transmit the information on the version of the changed setting information which is stored (for example, which is cached) at the time when the keep-alive response message is transmitted to the electronic device 100 in operation 521.
The electronic device 100 compares the information on the version of the changed setting information received from the push server 201 with information on a pre-stored version of setting information in operation 523. When there is no difference between the information on the version of the changed setting information received from the push server 201 and the information on the pre-stored version of the setting information as a result of the comparison, the electronic device 100 proceeds to operation 503 to collect log information.
When there is a difference between the information on the version of the changed setting information received from the push server 201 and the information on the pre-stored version of the setting information as a result of the comparison, the electronic device 100 may make a request for the setting information to the provisioning server 202 to update the setting information in operation 525.
The provisioning server 202 having received the request for the setting information from the electronic device 100 may transmit the stored changed setting information to the electronic device 100 in operation 527.
The electronic device 100 receives setting information and information on a version of the setting information received from the provisioning server 202 in operation 601. The electronic device 100 may receive the setting information and the information on the version of the setting information and store the received information in the storage unit 140, and the controller 170 may control log information and a push service by using the stored setting information. For example, the electronic device 100 may transmit a keep-alive message and/or log information to the push server 201 according to a keep-alive message transmission period included in the setting information. At this time, the transmission period may be included in the setting information transmitted from the provisioning server 202 or may be internally configured by the electronic device 100.
The electronic device 100 collects log information in operation 603. For example, the log information may include a use state and/or a processed content of an application stored in the electronic device, and a state and/or a processed content about the use of peripheral devices such as a sensor, a camera, and an audio device included in the electronic device 100. For example, the log information may include a use state and/or a processed content of a peripheral device included in the electronic device 100, an application included in the electronic device 100, and an application program included in the electronic device 100. The electronic device 100 may collect log information by identifying a target to be collected according to the log information collection setting value information included in the setting information. The collected log information may be stored in the storage unit 140 under a control of the controller 170. The log information collection setting value information may include setting values used for collecting log information, such as a limited number of transmissions of log information at one time, a limited number of transmissions of log information in one day, a limited number of transmissions of log information for each application, a log information collection period, and a model name or an application name which is restricted from collecting log information.
The electronic device 100 determines whether a preset transmission period arrives in operation 605. The transmission period may be transmitted from the outside of the electronic device 100 or internally configured by the electronic device 100. The electronic device 100 determines whether a transmission period when the keep-alive message for maintaining a push channel is transmitted to the push server 201 arrives in operation 605. When the preset transmission period does not arrive, for example, when the transmission period when the keep-alive message for maintaining the push channel is transmitted to the push server 201 does not arrive, the electronic device 100 continuously collects log information.
When the preset transmission period arrives, for example, the transmission period when the keep-alive message for maintaining the push channel is transmitted to the push server 201 arrives, the electronic device 100 generates the keep-alive message in operation 607.
When the keep-alive message for maintaining the push channel is generated, the electronic device 100 may transmit the keep-alive message and collected log information to the push server 201 in operation 609. For example, the electronic device 100 may transmit log information, which is collected at the time when the keep-alive message for maintaining the push channel is transmitted, to the push server 201 in operation 609.
The electronic device 100 may receive a keep-alive response message corresponding to a response message of the keep-alive message and changed information on the version of the setting information from the push server 201 in operation 611. For example, the electronic device 100 may receive the changed information on the version of the setting information at the time when the keep-alive response message corresponding to the response message of the keep-alive message is received from the push server 201 in operation 611.
The electronic device 100 may determine whether there is a difference between the changed information on the version of the setting information received from the push server 201 and pre-stored information on a version of setting information in operation 613. When there is no difference between the pre-stored version of the setting information and the changed information on the version of the setting information, the electronic device 100 proceeds to operation 603 to collect log information.
When there is a difference between the pre-stored version of the setting information and the changed information on the version of the setting information, the electronic device 100 makes a request for transmitting the setting information to the provisioning server 202 in operation 615. The electronic device 100 receives the changed setting information from the provisioning server 202 after the provisioning server 202 transmits the same in response to the request for transmitting the setting information by the electronic device 100.
The provisioning server 202 transmits setting information and information on a version of the setting information to the electronic device 100 in operation 701. The electronic device 100 stores the setting information and the information on the version of the setting information received from the provisioning server 202. The setting information may include a log information collection setting value information for collecting log information such as an address of the push server to which one or more electronic devices 100 will transmit collected log information. The log information collection setting value information may include setting values used for collecting log information, such as a limited number of transmissions of log information at one time, a limited number of transmissions of log information in one day, a limited number of transmissions of log information for each application, a log information collection period, and a model name or an application name which is restricted from collecting log information. For example, the electronic device 100 transmits a keep-alive message and/or log information according to an address of the push server 201 included in the setting information. The electronic device 100 may identify a version of the collected log information of the electronic device 100 according to a log information configuration version included in the setting information and may identify a list of log information to be collected according to a log information configuration list included in the setting information. The electronic device 100 collects log information of the electronic device 100 according to the setting information in operation 703.
The admin server 203 may make a request for a particular operation command to the push server 201 in operation 705. The particular operation command may include a command to start collecting one or more pieces of log information, a command to stop collecting log information, a command to collect emergency log information, a command to stop collecting emergency log information, or a provision command. The command to start collecting log information instructs the electronic device 100 to start collecting log information according to a keep-alive period and the command to stop collecting log information instructs the electronic device 100 to stop collecting log information which has been collected according to a keep-alive period. The command to collect emergency log information instructs the electronic device 100 to start collecting log information regardless of a keep-alive period and the command to stop collecting emergency log information instructs the electronic device 100 to stop collecting log information which has been collected by the command to start collecting emergency log information. The provision command instructs the electronic device 100 to immediately receive changed setting information from the provisioning server 202. For example, the provision command is a command to instruct the electronic device 100 to exchange setting information with the provisioning server 202 according to the push request of the push server 201.
The push server 201 may make a request for the push to the electronic device 100 according to the request for the particular operation command of the admin server 203 in operation 707. The electronic device 100 performs a particular operation according to the push request of the push server 201 in operation 709. For example, when the particular operation command is the command to start collecting log information, the electronic device 100 performs an operation to start collecting the log information according to a keep-alive period in response to the push request of the push server 201. When the particular operation command is the command to stop collecting log information, the electronic device 100 performs an operation to stop collecting the log information which has been collected according to a keep-alive period in response to the push request of the push server 201. When the particular operation command is the command to collect emergency log information, the electronic device 100 performs an operation to start collecting the log information regardless of a keep-alive period in response to the push request of the push server 201. When the particular operation command is the command to stop collecting emergency log information, the electronic device 100 may perform an operation to stop collecting the log information which has been collected by the electronic device 100 according to the command to start collecting emergency log information. When the particular operation command is the provision command, the electronic device 100 may immediately receive the changed setting information from the provisioning server 202. For example, when the particular operation command is the provision command, the electronic device 100 performs an operation to exchange the setting information with the provisioning server 202 according to the push request of the push server 201.
The electronic device 100 may transmit a result of the particular operation to the push server 201 in operation 711. For example, the result of the particular operation may correspond to the transmission of the log information.
