Detailed Description
Reference will now be made in detail to exemplary embodiments, examples of which are illustrated in the accompanying drawings. When the following description refers to the accompanying drawings, the same numbers in different drawings refer to the same or similar elements, unless otherwise indicated. The implementations described in the following exemplary examples are not representative of all implementations consistent with the present disclosure.
The communication processing method and device based on the PBAP protocol are applied to a scene of synchronization information between a server and a client. For example, the method is applied to a synchronous scene of address book between the intelligent terminal and the vehicle-mounted equipment.
In the related art, when information synchronization is performed by communication based on the PBAP protocol, transmission of a notification message is not supported, so that when the server updates the information content of the client, the updated information content cannot be synchronized in real time to the client. For example, in a scenario for synchronizing an address book, if an entry adding operation, an entry deleting operation, and/or an entry modifying operation of the address book are performed on the intelligent terminal side, the update to the in-vehicle device cannot be synchronized. Therefore, in the current method for synchronizing information based on communication of the PBAP protocol, the situations of unequal and unmatched information between the client and the service end may occur, and the experience of users is poor.
The disclosure provides a communication processing method based on a PBAP protocol to realize real-time synchronization information. In the method, the server can immediately send a notice to the client after updating the information, and the client is notified to acquire corresponding updating operation, so that the effect of synchronous updating is realized.
The information related in the embodiment of the disclosure may be an address book, or may be a telephone notification, a short message, or the like. In the following examples, address books are sometimes used as examples.
Fig. 1 is a flowchart illustrating a communication processing method based on a PBAP protocol according to an exemplary embodiment, and as shown in fig. 1, the communication processing method based on the PBAP protocol is applied to a server, and the communication processing method based on the PBAP protocol includes the following steps.
In step S11, it is determined that the information stored in the server is updated, and the server establishes a communication connection with the client, and transmits the pre-update information to the client based on the PBAP protocol.
In the embodiment of the disclosure, the server and the client need to establish communication connection, and synchronously transmit information. The communication connection established may be a bluetooth communication connection. A private asynchronous link can be established between the server and the client to acquire information such as address book data, and the data direction is from the server to the client.
Under the condition that the service end and the client end need to establish communication connection, the client end can acquire the information stored in the service end. For example, the in-vehicle device may acquire address book data stored in the intelligent terminal.
The information stored by the server may be updated by adding information, deleting information, modifying information, and the like.
In step S12, a notification message is sent to the client, where the notification message is used to notify that the information stored in the server is updated.
In the embodiment of the 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.
In step S13, the acquisition client transmits an information acquisition request transmitted based on the notification message, and transmits information on which update has occurred to the client based on the information acquisition request.
In the embodiment of the disclosure, after receiving the notification message of data update, the client sends an information acquisition request to the server. After receiving the information acquisition request, the server transmits updated information to the client.
According to the communication processing method based on the PBAP protocol, when the data information of the server side is updated, the data of the client side is informed of the update. At this time, the client sends an information acquisition request, requesting the server to send updated data to the client. The server transmits the updated data information of the client to the client based on the information acquisition request sent by the client.
The following embodiments of the present disclosure describe a method for a server to send a notification message to a client in the foregoing embodiments of the present disclosure.
In one implementation, the embodiments of the present disclosure may perform sending of the notification message based on a private protocol command between the server and the client that can support sending of the notification message.
Fig. 2 is a flowchart illustrating a method of transmitting a notification message to a client, as shown in fig. 2, according to an exemplary embodiment, the method of transmitting a notification message to a client includes the following steps.
In step S21, a private protocol command supporting transmission of the notification message is determined.
The private protocol command supporting sending the notification message may be, for example, a private protocol command based on a bluetooth device control protocol (HFP), a private protocol command broadcasted based on a bluetooth low energy module (Bluetooth Low Energy Module, BLE) link, or a private protocol command based on a bluetooth socket (sock) link.
In the embodiment of the disclosure, the HFP protocol can enable the client to serve as a remote audio input and output mechanism of the audio gateway, and can provide a plurality of remote control functions, and has the advantage that considering the devices supporting the PBAP protocol, the HFP protocol is supported in most cases. The BLE link may be used to implement some baseband protocols, the underlying packet management protocol, which has the disadvantage of supporting both classical bluetooth and bluetooth low energy for both the server and client. The sock link is suitable for the same service end and is also suitable for the inter-process communication between the service end and the client end, and has the defect that an rf link needs to be additionally established, so that the system overhead is increased. Therefore, in the embodiment of the present disclosure, the private protocol command supporting sending the notification message may be determined according to actual needs.
In step S22, the notification message is carried in a private protocol command supporting transmission of the notification message, and the notification message is transmitted to the client.
In the embodiment of the disclosure, a notification message for indicating information update is carried between a server and a client which perform communication processing based on a PBAP protocol through a private protocol command, so that the notification message between the server and the client which perform communication processing based on the PBAP protocol is sent.
In the embodiment of the disclosure, an information field for carrying the notification message is newly added in a private protocol command supporting sending the notification message, and the information field is used for storing the updated data of the server side and the updated data so as to realize sending of the notification message.
The newly added information field comprises the number of information which is updated, the updating operation corresponding to the information which is updated and the information content which is updated.
In an example, taking address book information as an example, contact 1 is added, contact 2 is deleted, and the newly added information field may send updated address book information in the following data format: <2>, < add >, < contact 1>, < delete >, < contact 2>.
According to the embodiment of the disclosure, the information domain for bearing the notification message is newly added in the private protocol command supporting the transmission of the notification message, so that the client can conveniently read and understand the notification message, the readability is higher, and the processing efficiency is improved.
It can be understood that, in the related art, the server and the client that perform communication processing based on the PBAP protocol do not support the information update based on the notification message, so in the embodiment of the disclosure, the server and the client need to perform interaction negotiation before performing the information update, so as to determine that both the server and the client support the information update based on the notification message.
Fig. 3 is a flowchart illustrating a method for performing interactive negotiation with a client and determining that both the server and the client support information update based on a notification message according to an exemplary embodiment, and as shown in fig. 3, a method for performing interactive negotiation with a client and determining that both the server and the client support information update based on a notification message includes the following steps.
In step S31, the server acquires identification bit information sent by the client, where the identification bit information is used to identify whether information update based on the notification message is supported.
In the embodiment of the disclosure, the identification bit information may be carried in a private protocol command between the server and the client. For example, an identification bit may be added to the private protocol command based on the HFP protocol to identify whether information update based on the notification message is supported. Wherein, the identification bit can be a bit, and different values of the bit correspondingly indicate whether information updating based on the notification message is supported. Of course, the identification bit may also be a number with different values, so as to correspondingly indicate whether information update based on the notification message is supported. For example, 1 identification supports information update based on notification message, and 2 identification does not support information update based on notification message.
In step S32, if the identification bit information identification supports information update based on the notification message and the server supports information update based on the notification message, the server sends acknowledgement information supporting information update based on the notification message to the client, and determines that both the server and the client support information update based on the notification message.
According to the communication processing method based on the PBAP protocol, whether the server supports the private command of sending the notification message is determined through the new addition, when the server updates the local message, the notification message is sent to the client, and when the client receives the update notification and acquires the update operation of the server, the server sends the updated information quantity, the corresponding update operation and updated content of the local to the client.
Based on the same conception, the embodiment of the disclosure also provides a communication processing method based on the PBAP protocol, which is applied to the client.
The following embodiments of the present disclosure describe a communication processing method based on a PBAP protocol applied to a client.
Fig. 4 is a flowchart illustrating a method of PBAP protocol-based communication processing applied to a client according to an exemplary embodiment, and as shown in fig. 4, the method of PBAP protocol-based communication processing applied to a client includes the following steps.
In step S41, a notification message sent by the server is received, where the notification message is used to notify that the information stored by the server is updated.
In the embodiment of the present disclosure, the client may acquire information stored in the server, for example, the vehicle-mounted device may acquire address book data stored in the intelligent terminal, based on the situation that the server and the client have established communication connection. When the data of the server side is updated, the client side can receive a notification message which is sent by the server side and used for indicating that the information is updated through the established communication connection.
In the embodiment of the disclosure, the client receives the notification message sent by the server, and can determine that the information stored by the server is updated, and then can request the server to acquire the updated message.
In step S42, an information acquisition request is sent to the server, and updated information transmitted by the server based on the information acquisition request is received.
According to the communication processing method based on the PBAP protocol, when receiving the notification message sent by the server, the client sends an information acquisition request to the server, requests the server to send updated information, and further acquires the updated information of the server.
The following embodiments of the present disclosure describe a method for a client to receive a notification message sent by a server in the foregoing embodiments of the present disclosure.
In one implementation, the embodiments of the present disclosure may perform the receiving of the notification message based on a proprietary protocol command between the client and the server that can support receiving the notification message.
Fig. 5 is a flowchart illustrating a method of receiving a notification message transmitted by a server, according to an exemplary embodiment, and the method of receiving a notification message transmitted by a server, as shown in fig. 5, includes the following steps.
In step S51, a private protocol command for sending a notification message is based on the determined support.
Wherein the private protocol commands supporting sending notification messages include HFP-based private protocol commands, BLE link-based broadcast private protocol commands, or sock link-based private protocol commands. The private protocol commands supporting the sending of notification messages may be determined according to actual needs.
In step S52, a notification message carried in a private protocol command sent by the server is received.
In the embodiment of the disclosure, an information domain for carrying a notification message is newly added in a private protocol command received by a client. The newly added information field is used for storing the operation of updating data of the server and the updated data. The newly added information field comprises the number of data updating operations, the updating operation corresponding to the data information which is updated and the information content which is updated.
In an example, taking address book information as an example address book, contact 1 is added, contact 2 is deleted, and the newly added information field can send updated address book information in the following data format: <2>, < add >, < contact 1>, < delete >, < contact 2>.
Fig. 6 is a flowchart illustrating a method for determining that both parties support information update based on a notification message by performing interactive negotiation with a server according to an exemplary embodiment, and the method for determining that both parties support information update based on a notification message by performing interactive negotiation with a server, as shown in fig. 6, includes the following steps.
In step S61, an interaction negotiation is performed with the server, and it is determined that both the server and the client support information update based on the notification message.
In the embodiment of the disclosure, before the server and the client perform information update, interaction negotiation is required to determine that both the server and the client support the information update based on the notification message.
In step S62, identification bit information is sent to the server, where the identification bit information is used to identify that the client supports information update based on the notification message.
In this embodiment of the present disclosure, the client sends, to the server, identification bit information based on a private command in the HFP protocol, to identify whether the server supports information update based on the notification message, where the identification bit information may adopt different values corresponding to whether the client supports different states of information update based on the notification message.
In step S63, if the confirmation information that the server side supports the information update based on the notification message and that the client side supports the information update based on the notification message is received, it is determined that both the server side and the client side support the information update based on the notification message.
In the embodiment of the disclosure, the server receives the information update based on the notification message, and determines whether the server supports the information update based on the notification message, if so, the server receives the information update based on the notification message.
In an example of the disclosure, when both the server and the client support information update based on the notification message, a content monitor is registered at the server to monitor whether the server data is updated.

In the embodiment of the disclosure, the vehicle-mounted device side sends a private AT command through an HFP protocol, and sends a push notification whether the address book is supported to update information based on the notification message to the intelligent terminal. For example, the private AT command may be at+zzpbap. The at+zzpbap= < flag > is used for determining whether the intelligent terminal supports the address book to update information based on the notification message, where the parameter of the flag may be 1, 2 or other values. Wherein parameter 1 represents an open notification for indicating support for information update based on the notification message. Parameter 2 represents a shutdown notification to indicate that no information update based on the notification message is supported.
Fig. 7 is a signaling interaction flow diagram between a smart terminal and an in-vehicle device that determines support for information update based on notification messages according to an exemplary embodiment of the present disclosure. Referring to fig. 7, the in-vehicle device transmits identification bit information of at+zzpbap=1 to the intelligent terminal to indicate that the in-vehicle device supports information update based on the notification message. The intelligent terminal receives identification bit information of AT+ZZPBAP=1 sent by the vehicle-mounted equipment, and determines that the vehicle-mounted equipment supports information updating based on the notification message. The intelligent terminal determines that the intelligent terminal supports information updating based on the notification message and sends confirmation information supporting information updating based on the notification message to the vehicle-mounted equipment. And the vehicle-mounted equipment receives the confirmation information which is sent by the intelligent terminal and supports the information update based on the notification message, and determines that the intelligent terminal supports the confirmation information which supports the information update based on the notification message.
Further, in the embodiment of the disclosure, communication between the intelligent terminal and the vehicle-mounted device can be performed based on bluetooth. In one implementation, in the embodiment of the disclosure, in a system bluetooth application of an intelligent terminal, a content detector is registered to detect whether an address book of the intelligent terminal is updated, for example, adding an address book entry, deleting an address book entry, and the like. When the address book is detected to be updated, the updated address book is obtained.
The method for the content detector to acquire the address book update message of the intelligent terminal comprises the following steps: in the intelligent terminal Bluetooth application, the contact ID updated in real time and the last update time are saved. When the address book of the intelligent terminal changes, the latest update time of each address book entry is queried. And obtaining a newly added contact item, a deleted contact item and/or an updated contact item according to the time record of the last updating operation and the record of the contact IDs of all the current address book items locally stored in the intelligent terminal.
In the embodiment of the disclosure, a system bluetooth application obtains an entry of an update operation of an address book of an intelligent terminal, and sends a notification message to a vehicle-mounted device terminal through a private AT command in an HFP protocol. In the embodiment of the present disclosure, the information sent by the device side with the update operation may be in the following format:
ZZPBAP:<number>,<operation>,<name>[,…]。
Wherein, the number is the number of the following < operation >, < name > [, … ]; operation is notification details, wherein 1 indicates that the intelligent terminal performs an addition operation, 2 indicates that the intelligent terminal performs a deletion operation, and 3 indicates that the intelligent terminal performs a modification operation. The name is the name of the smart terminal update entry, e.g. "select/pb/1. Vcf". After the intelligent terminal performs the address book adding operation, for example, the notification sent to the vehicle-mounted device end is "… +zzpbap:1, telcom/pb/8.vcf …). Fig. 8 illustrates a signaling flow diagram for notification message transmission for an added address book, which is shown in an exemplary embodiment of the present disclosure.
After the intelligent terminal performs the operation of deleting the address book, the notification sent to the vehicle-mounted equipment end is … +ZZPBAP:1,2, telcom/pb/7.vcf …). Fig. 9 is a signaling flow diagram illustrating the sending of a notification message to delete an address book in an exemplary embodiment of the present disclosure.
After the intelligent terminal carries out the operation of modifying the address book, the notification sent to the vehicle-mounted equipment end is … +ZZPBAP:1,3, telcom/pb/6. Vcf …). Fig. 10 illustrates a signaling flow diagram of notification message transmission for address book modification shown in an exemplary embodiment of the present disclosure.
In the embodiment of the disclosure, after receiving the address book updating operation notification sent by the intelligent terminal, the vehicle-mounted device performs a corresponding acquiring action. The vehicle-mounted equipment end acquires a corresponding electronic business card (vcard) in the intelligent terminal or performs other corresponding updating operations according to information provided in the private AT command. The method for acquiring and updating the vehicle-mounted equipment end can refer to a Bluetooth PBAP protocol. For example, the intelligent terminal modifies the address book, the vehicle-mounted equipment terminal acquires 6.Vcf under the Bluetooth virtual path select/pb, and the intelligent terminal returns an update operation of 6. Vcf.
In the embodiment of the disclosure, when the server side information is updated under the condition that the server side and the client side are in communication connection, a notification message is sent to notify the client side that the data information of the server side is updated. The client initiates an information acquisition request to the server. The server transmits updated information to the client based on the PBAP protocol, so that the occurrence of unequal and unmatched information between the client and the server is eliminated, and the user experience is improved
