[0043] The example embodiments will be described in detail herein, with examples shown in the accompanying drawings. When the following description refers to the drawings, the same numbers in different drawings represent the same or similar elements unless otherwise indicated. The implementations described in the following example embodiments do not represent all implementations consistent with the present disclosure.

[0044] The communication processing method and device based on a PBAP protocol provided by the embodiments of the present disclosure are applied to a scenario of synchronizing information between a server and a client. For example, the scenario of synchronizing a contact list between an intelligent terminal and a vehicle-mounted device.

[0045] In the related art, when information is synchronized based on communication of a PBAP protocol, sending a notification message is not supported. Therefore, when a server updates information content of the server, the updated information content cannot be synchronized in real time to a client. For example, in the scenario of synchronizing a contact list, if an operation of adding an entry, an operation of deleting an entry, and / or an operation of modifying an entry of the contact list is performed on the intelligent terminal side, the vehicle-mounted device cannot be synchronized and updated. Therefore, in the method of synchronizing information based on communication of a PBAP protocol, the information between the client and the server can be unequal and mismatched, and the user experience is poor.

[0046] The present disclosure provides a communication processing method based on a PBAP protocol to realize real-time synchronization of information. In the method, the server can send a notification to the client immediately after updating the information, and the client can obtain the corresponding update operation to realize the effect of synchronization update.

[0047] In the embodiments of the present disclosure, the information can be a contact list, a telephone notification, a short message, etc. In the following embodiments, the contact list is taken as an example for illustration.

[0048] Figure 1 A flowchart of a communication processing method based on a PBAP protocol according to an exemplary embodiment is shown in FIG. 1. Figure 1 As shown in FIG. 1, the communication processing method based on the PBAP protocol is applied to a server, and the method of communication processing based on the PBAP protocol includes the following steps.

[0049] In step S11, it is determined that the information stored in the server is updated, and the server and the client establish a communication connection, and the information before the update is transmitted to the client based on the PBAP protocol.

[0050] In the embodiments of the present disclosure, the server and the client need to establish a communication connection and perform synchronization transmission of information. The established communication connection can be a Bluetooth communication connection. The server and the client can establish a private asynchronous link to obtain contact list data and other information, and the data direction is from the server to the client.

[0051] When the server and the client establish a communication connection, the client can obtain the information stored in the server. For example, the vehicle-mounted device can obtain the contact list data stored in the smart terminal.

[0052] The updated information stored in the server can be adding information, deleting information, and / or modifying information, etc.

[0053] In step S12, a notification message is sent to the client, and the notification message is used to notify that the information stored in the server is updated.

[0054] In the embodiments of the present disclosure, when the information of the server is updated, the server sends a notification message to the device to notify the client that the data stored in the server is updated.

[0055] In step S13, an information acquisition request sent by the client based on the notification message is obtained, and the updated information is transmitted to the client based on the information acquisition request.

[0056] In the embodiments of the present disclosure, after receiving the notification message of the data update, the client sends an information acquisition request to the server. After receiving the information acquisition request, the server transmits the updated information to the client.

[0057] The method for processing communication based on the PBAP protocol provided by the embodiments of the present disclosure can inform the client that the data of the server is updated when the data information of the server is updated. At this time, the client sends an information acquisition request to request the server to send the updated data to the client. The server transmits the updated data information of the server to the client based on the information acquisition request sent by the client.

[0058] The following embodiments of the present disclosure explain the method for sending the notification message from the server to the client in the above-mentioned embodiments of the present disclosure.

[0059] In an implementation, the embodiments of the present disclosure can send the notification message based on the private protocol command that can support sending the notification message between the server and the client.

[0060] Figure 2 is a flowchart of a method for sending a notification message to a client according to an exemplary embodiment, as shown in Figure 2 The method for sending a notification message to a client includes the following steps.

[0061] In step S21, a private protocol command that supports sending a notification message is determined.

[0062] For example, the private protocol command that supports sending a notification message can be a private protocol command based on a Hands-free Profile (HFP), a private protocol command based on a Bluetooth Low Energy Module (BLE) link for broadcasting, or a private protocol command based on a Bluetooth socket (sock) link.

[0063] In the embodiments of the present disclosure, the HFP protocol can allow the client to be a remote audio input and output mechanism of an audio gateway and can provide several remote control functions. The advantage is that most devices supporting the PBAP protocol support the HFP protocol in most cases. The BLE link can be used to execute some baseband protocols and underlying packet management protocols. The disadvantage is that the server and the client need to support classic Bluetooth and low-power Bluetooth at the same time. The sock link is suitable for both the same server and the inter-process communication between the server and the client. The disadvantage is that an additional rf link needs to be established, which increases the system overhead. Therefore, in the embodiments of the present disclosure, the private protocol command that supports sending a notification message can be determined according to actual needs.

[0064] In step S22, the notification message is carried in the private protocol command that supports sending the notification message, and the notification message is sent to the client.

[0065] In the embodiments of the present disclosure, a notification message indicating that information is updated is carried by a private protocol command between the server and the client based on the PBAP protocol, so as to realize the sending of the notification message between the server and the client based on the PBAP protocol.

[0066] In the embodiments of the present disclosure, an information field for carrying the notification message is added in the private protocol command supporting the sending of the notification message, and the operation of updating data of the server and the updated data are stored in the information field, so as to realize the sending of the notification message.

[0067] In the embodiments of the present disclosure, the information field includes the number of updated information, the update operation corresponding to the updated information, and the content of the updated information.

[0068] In an example, taking the address book information as an example, a contact 1 is added and a contact 2 is deleted, and the updated address book information can be sent in the following data format by the added information field: <2>, <add>, <contact 1>, <delete>, <contact 2>.

[0069] The embodiments of the present disclosure add the information field for carrying the notification message in the private protocol command supporting the sending of the notification message, which facilitates the reading and understanding of the client, has stronger readability, and improves the processing efficiency.

[0070] In the embodiments of the present disclosure, the server and the client need to interact and negotiate before updating the information, so as to determine that the server and the client both support the information update based on the notification message.

[0071] Figure 3 FIG. 1 is a flowchart of a method of interacting and negotiating with the client and determining that the server and the client both support the information update based on the notification message according to an example embodiment. Figure 3 As shown in FIG. 1, the method of interacting and negotiating with the client and determining that the server and the client both support the information update based on the notification message includes the following steps.

[0072] In step S31, the server obtains the identification bit information sent by the client, and the identification bit information is used to identify whether the information update based on the notification message is supported.

[0073] In the embodiment of the present disclosure, the identification bit information can be carried in the private protocol command between the server and the client. For example, an identification bit can be added in the private protocol command based on the HFP protocol to identify whether information updating based on the notification message is supported. The identification bit can be a bit, and different values of the bit correspond to indicating whether information updating based on the notification message is supported. Of course, the identification bit can also be a number with different values to correspond to indicating whether information updating based on the notification message is supported. For example, 1 indicates that information updating based on the notification message is supported, and 2 indicates that information updating based on the notification message is not supported.

[0074] In step S32, if the identification bit information indicates that information updating based on the notification message is supported, and the server supports information updating based on the notification message, the server sends confirmation information of supporting information updating based on the notification message to the client, and determines that both the server and the client support information updating based on the notification message.

[0075] The method for communication processing based on the PBAP protocol provided by the embodiment of the present disclosure adds a private command to determine whether the server supports sending a notification message, so that when the server updates the local message, the server sends a notification message to the client. When the client receives the update notification and obtains the update operation of the server, the server sends the information amount of the local update, the corresponding update operation, and the updated content to the client.

[0076] Based on the same concept, the embodiment of the present disclosure also provides a method for communication processing based on the PBAP protocol applied to a client.

[0077] The following embodiments of the present disclosure describe a method for communication processing based on the PBAP protocol applied to a client.

[0078] Figure 4 A flowchart of a method for communication processing based on the PBAP protocol applied to a client is shown according to an exemplary embodiment, as shown in Figure 4 The method for communication processing based on the PBAP protocol applied to a client includes the following steps.

[0079] In step S41, a notification message sent by the server is received, and the notification message is used to notify that the information stored by the server has been updated.

[0080] In the embodiment of the present disclosure, based on the fact that the server and the client have established a communication connection, the client can obtain the information saved in the server, for example, the vehicle-mounted device can obtain the contact list data stored in the smart terminal. When the server data is updated, the client can receive the notification message sent by the server to indicate that the information has been updated through the established communication connection.

[0081] In the embodiment of the present disclosure, the client receives the notification message sent by the server, can determine that the information stored by the server is updated, and then can request the server to obtain the updated message.

[0082] In step S42, an information acquisition request is sent to the server, and the updated information transmitted by the server based on the information acquisition request is received.

[0083] The communication processing method based on the PBAP protocol provided by the embodiment of the present disclosure, when the client receives the notification message sent by the server, sends an information acquisition request to the server, requests the server to send the updated information, and then obtains the updated message of the server.

[0084] The following embodiments of the present disclosure explain the method of receiving the notification message sent by the server in the above-mentioned embodiments of the present disclosure.

[0085] In one embodiment, the embodiment of the present disclosure can receive the notification message based on the private protocol command supported by the client and the server to receive the notification message.

[0086] Figure 5 A flow chart of a method for receiving a notification message sent by a server according to an exemplary embodiment is shown in FIG. 1. Figure 5 As shown in FIG. 1, the method for receiving a notification message sent by a server includes the following steps.

[0087] In step S51, the private protocol command supporting sending the notification message is determined.

[0088] The private protocol command supporting sending the notification message includes a private protocol command based on HFP, a private protocol command broadcasted based on BLE link, or a private protocol command based on sock link. The private protocol command supporting sending the notification message can be determined according to actual needs.

[0089] In step S52, the notification message carried in the private protocol command sent by the server is received.

[0090] In the embodiment of the present disclosure, the private protocol command received by the client adds an information field for carrying the notification message. The added information field is used to store the operation of updating the data of the server and the updated data. The added information field includes the number of update data operations, the update operation corresponding to the updated data information, and the updated information content.

[0091] In an example, a contact list is taken as an example, contact 1 is added, and contact 2 is deleted. The new information field can send the updated contact list information in the following data format: <2>, <add>, <contact 1>, <delete>, <contact 2>.

[0092] Figure 6 is a flowchart of a method for interacting with a server to negotiate and determine that both sides support information updating based on a notification message according to an example embodiment, as shown in Figure 6 The method for interacting with a server to negotiate and determine that both sides support information updating based on a notification message includes the following steps.

[0093] In step S61, the server and the client are interacted with to negotiate and determine that both the server and the client support information updating based on a notification message.

[0094] In the related art, the server and the client that perform communication processing based on the PBAP protocol do not support information updating based on a notification message. Therefore, in the embodiment of the present disclosure, the server and the client need to interact with each other before information updating to determine that both the server and the client support information updating based on a notification message.

[0095] In step S62, identification bit information is sent to the server, and the identification bit information is used to identify that the client supports information updating based on a notification message.

[0096] In the embodiment of the present disclosure, the client sends identification bit information based on a private command in the HFP protocol to the server to identify whether the server supports information updating based on a notification message. The identification bit information can correspond to different states of whether the client supports information updating based on a notification message by using different values.

[0097] In step S63, if the server sends confirmation information that the server supports information updating based on a notification message, it is determined that both the server and the client support information updating based on a notification message.

[0098] In the embodiment of the present disclosure, the server receives the judgment of whether the server supports information updating based on a notification message transmitted by the client. If the server supports information updating based on a notification message.

[0099] In an example of the present disclosure, the server and the client both support information updating based on a notification message, and the content monitor is registered in the server to monitor whether the data of the server is updated. When the information of the server is updated, the server sends a notification message to the client, which includes the number of updated data operations, the corresponding update operation of the updated data information, and the updated information content, to realize the update information synchronization push to the client, eliminate the occurrence of the information inequality and mismatch between the client and the server, and thus help to improve the user experience.

[0100] In the following examples of the present disclosure, the communication record updating between the intelligent terminal and the vehicle-mounted device is taken as an example to illustrate the method related to the above-mentioned examples of the present disclosure.

[0101] In the examples of the present disclosure, after the intelligent terminal and the vehicle-mounted device normally establish the Bluetooth connection, the vehicle-mounted device end acquires the communication record information of the intelligent terminal. At this time, the intelligent terminal modifies the communication record, and the vehicle-mounted device end cannot update simultaneously.

[0102] In the examples of the present disclosure, the vehicle-mounted device end sends a private AT command through the HFP protocol to send the intelligent terminal whether to support the communication record information updating based on the notification message. For example, the private AT command can be AT+ZZPBAP. Wherein, AT+ZZPBAP= <flag>This parameter is used to determine whether a smart terminal supports updating contacts based on notification messages. The `flag` parameter can be 1, 2, or other values. Parameter 1 indicates that notifications are enabled, meaning that updates based on notification messages are supported. Parameter 2 indicates that notifications are disabled, meaning that updates based on notification messages are not supported.

[0103] Figure 7 This is a flowchart illustrating a signaling interaction process between a smart terminal and an in-vehicle device, as shown in an exemplary embodiment of this disclosure, to determine whether information updates based on notification messages are supported. (See also...) Figure 7 As shown, the in-vehicle device sends an identifier (AT+ZZPBAP=1) to the smart terminal to indicate that the in-vehicle device supports information updates based on notification messages. The smart terminal receives the identifier (AT+ZZPBAP=1) from the in-vehicle device and confirms that the in-vehicle device supports information updates based on notification messages. The smart terminal, having confirmed that it supports information updates based on notification messages, sends a confirmation message to the in-vehicle device. The in-vehicle device receives this confirmation message and confirms that the smart terminal supports information updates based on notification messages.

[0104] Furthermore, in this embodiment of the present disclosure, the smart terminal and the in-vehicle device can communicate via Bluetooth. In one implementation, within the system Bluetooth application of the smart terminal, a content detector is registered to detect whether the smart terminal's address book has been updated, such as adding, deleting, or re-deleting address book entries. When an update to the address book is detected, the updated address book is retrieved.

[0105] The method by which the content detector obtains contact update messages from the smart terminal is as follows: In the smart terminal's Bluetooth application, the contact IDs and last update times are saved in real-time. When changes occur in the smart terminal's contact list, the latest update time for each contact entry is queried. Based on the time record of the last update operation saved locally on the smart terminal and the record of contact IDs for all current contact entries, newly added contact entries, deleted contact entries, and / or updated contact entries can be determined.

[0106] In this embodiment, the system Bluetooth application obtains the update operation entry from the smart terminal's address book and sends a notification message to the vehicle-mounted device via a private AT command in the HFP protocol. In this embodiment, the device may send the update operation information in the following format:

[0107] ZZPBAP: <number> ， <operation> ， <name>[,... ].

[0108] wherein number is the number of subsequent syllables <operation> ， <name>The number of combinations of [,...]; operation is a notification detail, wherein 1 indicates that the intelligent terminal performs an adding operation, 2 indicates that the intelligent terminal performs a deleting operation, and 3 indicates that the intelligent terminal performs a modifying operation. The name is the name of the intelligent terminal update entry, for example, "telecom / pb / 1.vcf". For example, after the intelligent terminal performs the adding operation of the address book, the notification sent to the vehicle-mounted device end is "... + ZZPBAP: 1, 1, telecom / pb / 8.vcf...". Figure 8 A signaling flow chart for sending a notification message of adding an address book in an example embodiment of the present disclosure is shown.

[0109] After the intelligent terminal performs the deleting operation of the address book, the notification sent to the vehicle-mounted device end is "... + ZZPBAP: 1, 2, telecom / pb / 7.vcf...". Figure 9 A signaling flow chart for sending a notification message of deleting an address book in an example embodiment of the present disclosure is shown.

[0110] After the intelligent terminal performs the modifying operation of the address book, the notification sent to the vehicle-mounted device end is "... + ZZPBAP: 1, 3, telecom / pb / 6.vcf...". Figure 10 A signaling flow chart for sending a notification message of modifying an address book in an example embodiment of the present disclosure is shown.

[0111] In the embodiment of the present disclosure, after the vehicle-mounted device end receives the update operation notification of the address book sent by the intelligent terminal, the corresponding acquisition action is made.
