It should be noted that, the terminal in the present application may be a terminal device with a communication function, such as a mobile phone, a tablet computer, a desktop PC, a notebook computer, a high-definition television, a player, a sound box, an electronic book, and the like.

Embodiments of the present application will be described in further detail below with reference to the accompanying drawings.

Fig. 1 shows a scenario diagram of information synchronization of a plurality of terminals under a complex network. Referring to fig. 1, the scene includes a television 101, a tablet 102, a mobile phone 103, a watch 104, a speaker 105, an electronic book 106, a lightweight electronic device 107, and a notebook 108. A plurality of different connection states are adopted between the terminals, including WiFi connection, bluetooth connection and NFC connection. For example, for WiFi connection, the television 101 may be connected to the tablet 102, the computer 108, and the mobile phone 103 through a wireless router via a wireless network; for bluetooth connection, the mobile phone 103 and the watch 104 and the voice box can be in bluetooth connection, the television 101 and the electronic book 106 can be in bluetooth connection, and the lightweight electronic device 107 can be in bluetooth connection with the television 101 and the notebook computer 108 respectively; the sound box 105 and the electronic book 106 may be NFC connected. And the operating systems adopted by the devices are different. Wherein, television 101 adopts a hong operation system (Harmony Operating System, HMOS) and an emotion operation system (Emotion User Interface, EMUI), tablet computer 103 and mobile phone 103 adopt EMUI systems, watch 104, sound box 105 and electronic book 106 adopt HMOS 1.0 systems, lightweight electronic equipment is no system equipment, and notebook computer 108 adopts window 10 systems. The terminals may be connected by other connection methods, such as optical fiber, infrared, GMS, CDMA, LTE, or 5G.

In the local area network composed of the plurality of terminals, the network is dynamic, various and complex because the system used by each terminal and the software running on each terminal are different in types and quantity, different in connection modes, and even a newly added terminal or the like may exist in the local area network.

In such a complex network scenario, if an activity item needs to be cooperatively completed by using a plurality of terminals in the local area network, for example, when a game is completed, it is required that each terminal can query at any time which service information is available between each terminal, and call a responding device to cooperatively complete an action of the game, for example, a mobile phone runs and controls the game, a television displays a main game picture, a watch records the time of the game, or sends a vibration prompt, and a sound effect of the game is played by a sound box.

According to the method and the system, the service information management function is built in each terminal, all service information in the local and/or remote terminals is managed through the service information management function, and all terminals communicate by adopting a unified preset protocol when the service information is synchronized through the service management function, so that the service information of all terminals in the local area network is stored in each terminal.

In contrast, in the synchronization process of service information in the prior art, all services are registered on a fixed central node, service management is implemented through the central node, service information of each terminal is queried and synchronized, the complex and dynamic local area network is not provided with the fixed central node, and some terminals are not connected with the central node and cannot be queried and synchronized. In addition, another service mode in the prior art is to query and synchronize service information through a point-to-point connection mode, and the queried result cannot be shared by other terminals. Thus, the two methods of synchronizing service information are not suitable for the dynamic, complex synchronization of service information for each terminal in a local area network as described in this application.

The service information may be service information corresponding to a function or an application owned by each terminal, for example, a payment function owned by a payment device, an play function owned by a sound box, an application for data analysis and processing owned by a mobile phone, a large screen display function owned by a television, and the like.

According to the embodiment of the application, the terminals can adopt a unified preset protocol to realize the synchronization of service information of all terminals in the local area network, so that the problem that the terminals cannot be synchronized normally due to the difference of different connection modes, operating systems and the like is solved. In step S520, the terminal a and the terminal B synchronize service information based on the unified preset protocol. At this time, both terminals a and B will store service information of terminals a and B. In step S521, the terminal a and the terminal C perform synchronization of service information. Thus, both terminals a and C will store service information for terminals a, B and C. In step S522, the terminal C and the terminal D perform synchronization of service information. Thus, both terminals C and D will store service information for terminals a, B, C, D. In step S523, the terminal D and the terminal B perform synchronization of service information. In this way, terminal B will also store service information for terminals a, B, C, D. In step S524, the terminal a and the terminal B perform synchronization of the service information again. Thus, terminal a will also store service information for a, B, C, D.

When the plurality of terminals complete the synchronization, so that each of the plurality of terminals a, B, C, D stores service information of all terminals in the local area network. The terminals A, B, C and D all store the service information of other terminals in the local area network, so that the functions and the like in the corresponding terminals can be inquired and called in the terminal, and the service information management function in the terminal is realized.

By setting the service information management function in each terminal, after a plurality of terminals form a dynamic and complex local area network, when the terminals need to cooperatively complete a task target, the terminals can know which functions are provided with each other and call the functions, and a user can complete the task target to be completed through the terminals, so that the user experience is improved.

It should be noted that, in the above flowcharts, the order of steps S510 to S513 in the process of establishing a connection is merely an exemplary illustration, and the present application is not limited thereto, and may be other orders or synchronous completion.

It should be noted that, in the process of synchronizing the service information, steps S520 to S524 are merely exemplary descriptions, and the present application is not limited thereto, and may be performed in other sequences or synchronously.

In the service information synchronization method, details of a unified protocol used by each terminal to synchronize service information and a service information management function in each terminal are described below.

In one embodiment of the present application, the terminals in the local area network communicate using a unified preset protocol. The preset protocol may be preset in the production process, or may be added or changed after the terminal is produced and shipped, for example, an application for implementing unified use of the preset protocol is downloaded in each terminal, so as to implement unified use of the preset protocol by each terminal. When the terminals need service information synchronization, each terminal adopts a unified preset protocol, initiates or receives a service information synchronization request, and receives or transmits a response aiming at the service information synchronization request, so that the synchronization of the service information is realized. The preset protocol may include definitions of a service information synchronization protocol, specifically including definitions of a protocol basic format, a protocol header, an action, an object type, a handshake protocol, a get action protocol, a send action protocol, etc., and specifically, the definition of the protocol basic format is shown in table 1 below.

Table 1 protocol basic format

Protocol header	Action	Object type	Quantity of	Object size	Data
						6byte	1byte	1byte	2byte	2byte

Wherein the protocol header may be represented by 6 bytes as shown in table 4 below.

Table 2 protocol header definitions

The letter DSIS in table 2 is an abbreviation for device service information synchronous device service information synchronization, and in the device communication process, a message with the identifier is used to represent a request message or a response message for service information synchronization. It should be noted that the protocol header may be other numbers or letters, which are not limited herein.

The handshake shown in table 3 is denoted 0, get is denoted 1, put is denoted 2. As an exemplary scenario, terminal a wants to acquire service information of terminal B, first handshake to establish a connection, then terminal a sends a get request to terminal B, the get request indicates the object type to be acquired, and terminal B responds to the request and then sends (put) data corresponding to the object type in the request to terminal a. The specific definitions for the handshake, get, and put protocols in action according to one embodiment of the present application are shown in tables 4-6.

Table 4 handshake protocol definitions

Protocol header	Action	Object type	Quantity of
				6byte	0	0	0

The connection relationship of the two devices is determined by a handshake protocol before the two terminal devices communicate. As shown in fig. 6, a schematic diagram of a handshake procedure between two terminal devices, device 601 sends handshake request data to device 602, and device 602 responds to the handshake data and establishes a connection.

The definition of the get action protocol as the terminal is to implement is exemplarily shown in table 5 below.

Table 5get action protocol definition

Protocol header	Action	Object type	Quantity of	Object identification
					6byte	1	1～255	0

The object identifier of the get may include a device list, device information, a service list, service information, and a corresponding feature value. Specific description of object identification is described in detail in the following embodiments. The protocol definition is exemplarily shown in table 6 below, if the terminal is to implement the put action.

TABLE 6put action protocol definition

Protocol header	Action	Object type	Quantity of	Object size	Object data
						6byte	2	1～255	0～65535	0～65535

The object data in table 6 may include device information structure and service information structure data, among others. Among them, the device information structure and the service information structure data are specifically described in the following embodiments. With respect to the object types described in table 1, the following table 7 is exemplary.

TABLE 7 object type definition

In table 7, the object type indicates an object of transmission or reply of an action, for example, when the terminal a transmits a get request to the terminal B, the object type 1,1 in the request represents a device list feature value, and the terminal B responds to the request to send data put corresponding to the device list feature value to the terminal B. The device list feature value in table 7 is a hash value calculated by the terminal based on the device list, the device feature value is a hash value calculated by the terminal based on the device information, and the service feature value is a hash value calculated by the terminal based on the service information. That is, when the value of the object type in the request is 1, 3, 5 or 7, then the data of the reply object type is the device list feature value, the device feature value, the service list feature value or the service feature value after responding to the request. By adopting the characteristic value mode, when the service information of the terminal is changed, only the data with different characteristic values are synchronized, so that the data transmission efficiency can be improved. For example, when the service information of the terminal B is changed, in order to avoid repeated synchronization of the data, the changed data is first found. The terminal A firstly requests the characteristic value of the equipment list, the terminal B sends the characteristic value (hash value) of the equipment list to the terminal A, the terminal A compares the characteristic value of the equipment list with the characteristic value of the equipment list of the terminal B before the change, when the two characteristic values of the equipment list are found to be different, the terminal A indicates that the equipment list is changed, at the moment, the terminal A sends a request to the terminal B, the value of the object type contained in the request is 2, the value 2 is expressed as the equipment list, and the terminal B sends the equipment list of the terminal A according to the request, so that the synchronization of the equipment lists among the terminals is realized. If the characteristic values of the two device lists before and after the change are the same, the device characteristic values can be directly requested for comparison without requesting the device list. Thereby realizing the synchronization of the service information. The method can effectively reduce the data transmission quantity and improve the data transmission efficiency.

The identification of objects in the get action protocol is described below as shown in Table 8.

Table 8 get's object identification

Object type	Identification mark
		List of devices feature values	0
List of devices	0
		Device characteristic value	DeviceID
Device information	DeviceID
		Service list feature values	DeviceID
Service list	DeviceID
		Service characteristic value	ServiceID
Service information	ServiceID

The device feature value, the device information, the service list feature value, and the identifier corresponding to the service list in table 8 are the device unique identifier "DeviceID", and the service feature value and the service information identifier are the unique identifier "ServiceID" of the service. That is, in the process of Get a service information, firstly, the DeviceID is obtained to determine a designated device, and service information corresponding to ServiceID is found in the service list of the device, so as to obtain service information on a specific designated device. The unique identification of the device comprises a set of all addresses based on the communication connection of the terminal and other terminals in the network, each terminal can calculate the set of all addresses of the terminal and other terminals in the local area network into a 4-byte hash value according to a hash algorithm, and in the transmission process, the resource occupation ratio is small, so that the transmission is convenient.

Referring to fig. 7, fig. 7 shows a schematic diagram of a connection manner included in the terminal. As shown in fig. 7, the terminal device a is connected with the terminal device B through bluetooth in the local area network and is connected with the device C through wifi, all unique identifiers of the terminal device a include an IP address of the wifi connection, an address of the bluetooth connection, a product Serial Number (SN) fixed by itself and a mobile device identification code (International Mobile Equipment Identity, IMEI), the terminal device a calculates the unique identifiers into hash values of 4 bytes through a hash algorithm, if Ox35fe is obtained after calculation, the Ox35fe is used as the unique identifier of the terminal device a to inform other terminals, and all unique identifiers of the terminal device B include the bluetooth address connected with the device a and the product serial number fixed by the device B itself. The terminal device B calculates all unique identifiers owned by the terminal device B through a hash algorithm to obtain a 4-byte hash value, such as Ox24cc, and informs other terminals of Ox24cc as the unique identifier of the terminal device B. All unique identifiers of the terminal equipment C comprise ip addresses connected with the terminal equipment A through WiFi, the terminal equipment C calculates all unique identifiers owned by the terminal equipment C through a hash algorithm to obtain 4-byte hash values, such as Oxad27, and the Oxad27 is used as the unique identifier of the terminal equipment C to inform other terminals. Under various connection states, each device has a unique identifier, so that the devices can conveniently know the addresses of each other and synchronize the service information of each other, and the transmission speed is high by adopting the hash value identification mode with only a few bytes.

According to the preset protocol, the communication process can be realized between terminals in a dynamic and complex local area network, and the service information can be synchronized.

The following describes the process of data interaction between devices with reference to fig. 6 and 8, and fig. 8 shows a schematic diagram of the process of data interaction between terminal devices, and as shown in fig. 8, after handshake between the terminal 601 and the terminal 602, the terminal 601 initiates a get request to obtain service information from the terminal 602. The request includes an object type required by the terminal 601, for example, a device feature value or device information. And the object type identifies a corresponding device address or service address. That is, the terminal device 601 informs the terminal 602 of the object type to be acquired and the address corresponding to the object type by means of transmitting the request, and when the terminal 602 receives the request, data corresponding to the object type, such as a device characteristic value (hash value calculated based on the device information), is transmitted to the terminal 601 according to the address in the request, and the terminal 601 stores the object data locally. And when the terminal 601 sends a request, its own service information is sent to the terminal 602, and the terminal 602 synchronizes the acquired service information to the local. In addition, the terminal 602 may actively transmit service information to the terminal 601.

In the embodiment of the present application, the service information management function provided for each terminal in the local area network can manage the service information of the other terminal. Wherein the management of the service information by the service information management function comprises a definition of a service information data structure, which further may comprise a device information structure and a service information structure. The service information management function of each terminal can manage its own service information data structure in the form shown in tables 9 and 10, and exemplary contents thereof can be seen from tables 9 and 10.

The device information structure in table 9 may include a list of devices and service information, where the fields in the service information that must be filled include a version number of the device information description, a unique identifier of the device, and field information such as a list of externally accessible services, where a record in "serviceist" may be accessed by other devices, and other devices may only access services in this list.

Exemplary contents of the service information structure of each terminal may be as shown in table 10.

The service information structure in table 10 includes descriptions of service information and interface types possessed by the terminal, and in particular, the service information may include a version number such as "hh.mm.11" for the description of the service information; service unique identifiers, such as "domain name, company name, class, service name"; service interface version numbers, such as "hhh.mmm.111.Ext"; the interface type list is supported, and other service lists are relied on, and the interface type standard can be AIDL, HIDL, ZIDL, RESTFUL, customizable extension type and the like. After service information of a plurality of terminals in a local area network is synchronized, each terminal can store a device information structure and a service information structure which are in one-to-one correspondence with each terminal, each terminal finds out the terminal device through unique identifiers of the device information in the service information, and the function of each terminal is known.

The following describes a service information synchronization method for a terminal in a local area network according to the present application, taking a game scenario as an example.

Referring to fig. 9a, fig. 9a shows a game scene graph. The scene comprises a local area network consisting of a mobile phone 901, a television 902, a sound box 903 and a watch 904, wherein the mobile phone 901 is connected with the television 902 through WiFi, the sound box 903 is connected with the television 902 and the mobile phone 901 through Bluetooth, and the watch 904 is connected with the mobile phone 901 through WiFi p2p point-to-point. The devices all use the preset protocol described in the above embodiments to communicate, so as to realize synchronization of service information. The service information of the television 902 includes a large screen display function, the service information of the sound box 903 is provided with an external play function, the mobile phone 901 has a handle control function, and the watch 904 has a vibration function. After the service information synchronization is finished, the user can view the service information on each device through the mobile phone 901 and select a corresponding function to complete the game. As shown in the operation schematic diagram of the mobile phone interface in fig. 9b, the user clicks the watch by using the name of the synchronized terminal displayed on the mobile phone interface 910, the mobile phone interface 920 displays the vibration function of the watch 904, and after clicking the vibration function, the mobile phone 901 receives the instruction of the user to call the application corresponding to the vibration function of the watch, so as to start the scene of setting vibration in the game scene. Also, by this mode, the mobile phone 901 turns on the large screen display function of the television 902, the game handle function of the mobile phone 901 and the play function of the speaker 903, and the game designated by the user is completed cooperatively by the four terminals. And the experience of the user is improved.

The following describes a service information synchronization procedure between a mobile phone and other terminals in various scenarios, with reference to the scenario shown in fig. 9a as an example.

Scenario 1, when handset 901 is newly joining a local area network. Referring to fig. 10, fig. 10 shows a flowchart of synchronization between a mobile phone and terminal information in a local area network, which may specifically include:

in step S1001, the mobile phone 901 generates a unique identifier. Specifically, the mobile phone 901 integrates the ip address connected to the television, the bluetooth address connected to the sound box 903, the address connected to the WiFi p2p of the watch 904, and the IMEI identifier of the mobile phone together to calculate, obtain a 4-byte hash value, and uses the hash value as a unique identifier for notifying other terminals.

In step S1002, the connection mode of the device to the local area network is determined, i.e. the point-to-point connection mode or the WiFi connection through the intermediary is determined. When the mobile phone 901 determines that the network access mode is a point-to-point connection mode, as in the scenario shown in fig. 9a, the mobile phone 901 determines that it is connected to the sound box 903 by bluetooth and is connected to the watch 904 by WiFi p2p, and step S1003 is executed, that is, a transmission channel is determined, and service information synchronization is initiated to the sound box 903 and the watch 904. After synchronization is completed, handset 901 stores its own service information, speaker 903, and watch 904, respectively.

When the mobile phone 901 determines that the network connection mode is not the point-to-point connection, step 1004 is executed to continuously determine whether the network connection mode is the IP connection, and when the mobile phone 901 determines that the network connection mode is the IP connection, for example, the mobile phone 901 determines that the network connection mode is the WiFi connection, step 1005 is executed by the mobile phone 901, that is, the broadcast service is on line and waits to be synchronized. After receiving the service online notification of the mobile phone 901, the television 902 in the local area network actively initiates a service information synchronization request to the mobile phone 901, where the service information request includes a unique identifier of the television and own service information data, and the mobile phone 901 responds to the service information synchronization request, sends own service information to the television 902, and stores the service information of the television 902 locally. And (5) completing the synchronization process of the two.

If the network method of the connection determined by the mobile phone is neither point-to-point connection nor ip connection, step S1006 is executed, and it is determined that the connection is abnormal, and synchronization is terminated.

The order of judgment in steps S1002 and S1004 may be changed, and is not limited herein.

Scene 2, when a new terminal is added in the local area network, the network equipment mobile phone 901 receives the broadcast online service of the new terminal, and after determining the transmission channel, actively initiates service information synchronization to the new terminal, wherein the service information comprises unique identification generated by the mobile phone 901, and the specific generation method can be referred to scene 1 and is not described herein. And after the new equipment responds to the service request, the service information synchronization of the new equipment and the new equipment is realized.

Scene 3, when a service information change occurs in a terminal in a local area network, referring to fig. 11, fig. 11 shows a flowchart of synchronization of a mobile phone with service information of the terminal with the service information change. The following steps are described by taking the mobile phone as an execution main body, and specifically comprise the following steps:

step S1101, a terminal list in the local area network is acquired.

Step S1102 judges whether the service information of all terminals in the terminal list has been completed synchronously. When it is determined that the service information of all the terminals has been completed in synchronization, step S1103 is executed, and the synchronization is ended. When judging that the service information of the terminal is not synchronized, executing the synchronization of the service information of the changed part of the terminal, and specifically comprising the following steps:

step S1104, obtaining changed service information of the terminal.

In step S1105, a transmission channel with the terminal is determined, and the channel determination may first determine that the connection mode is confirming the transmission channel.

Step S1106, initiate service information synchronization, and complete information synchronization. After the synchronization of the changed service information is finished, the mobile phone terminal can continuously monitor the terminal equipment in the local area network to change the service information so as to synchronize the service information among the terminals in time.

In the process of information synchronization, a large amount of repeated data exists, and in order to reduce the amount of synchronization data, each terminal can use a differential synchronization method to search step by step, so that only the changed service information is synchronized. The following describes an example of the change of the service information of the wristwatch.

Referring to fig. 12 in conjunction with fig. 9, fig. 12 shows a schematic diagram of the structure of differential synchronization. As shown in fig. 12, includes a handset 901 and a wristwatch 904. The handset 901 compares the pre-change service information of its previously stored watch with the stored post-change service information. The service information structure table is first compared as shown in fig. 12, and the table may refer to the table shown in table 2. The mobile phone 901 communicates with the watch 904 by adopting a preset protocol, during the communication process, the mobile phone 901 firstly obtains the hash value Ox34d3 of the service information structure table of the watch 904, compares the hash value Ox34d3 with the hash value Ox258c of the service information structure table before the change of the watch 904, judges whether the two are the same, if the two are different, the information in the table is changed, sequentially judges whether the hash values of the service information lists of the two devices are the same, and when the hash values of the service information lists are different, the hash values of the service content in the list are judged to be the same after the hash values are confirmed to be different, until different service contents are found, and the service contents are updated into the service information corresponding to the watch 904 in the mobile phone 901.

It should be noted that, the synchronization process of the service information of other terminals in the present application is the same as that of the mobile phone, and specific reference may be made to the synchronization process of the service information of the mobile phone, which is not described herein.
