Detailed Description
For the purpose of making the objects, technical solutions and advantages of the present application more apparent, the technical solutions of the present application will be clearly and completely described below with reference to the accompanying drawings, and it is apparent that the described embodiments are some embodiments of the present application, not all embodiments. All other embodiments, which can be made by those skilled in the art based on the embodiments of the application without making any inventive effort, are intended to be within the scope of the application.
In the present application, it should be construed that the terms "", "" are used for descriptive purposes only and are not to be construed as indicating or implying relative importance. Furthermore, "at least one" means one or more, and "a plurality" means two or more. "and/or", describes an association relationship of an association object, and indicates that there may be three relationships, for example, a and/or B, and may indicate: a alone, a and B together, and B alone, wherein a, B may be singular or plural. The character "may be a relationship that generally indicates that the front and rear associated objects are an" or ". "at least one of" or the like means any combination of these items, including any combination of single item(s) or plural items(s). For example, at least one (one) of a, b, or c may represent: a alone, b alone, c alone, a combination of a and b, a combination of a and c, b and c, or a combination of a, b and c, wherein a, b, c can be single or multiple.
Fig. 1 is a schematic diagram of an application scenario provided by the present application. The application scenario shown in fig. 1 is a one-to-one file distribution scenario. One-to-one file distribution refers to one user terminal sending a file to another user terminal. In fig. 1, a user terminal transmitting a file is represented by a user terminal 1, a user terminal receiving a file is represented by a user terminal 2, and the user terminal 1 interacts with the user terminal 2 through a server. In the scenario shown in fig. 1, the user terminal 1 is also called a transmitting terminal and the user terminal 2 is also called a receiving terminal.
Referring to fig. 2, in the present MCData specification, when the user terminal 1 transmits a certain file to the user terminal 2, the method includes the following steps:
When the file is transmitted by a hypertext transfer protocol (Hypertext Transfer Protocol, HTTP), the user terminal 1 firstly uploads the file to a server, then sends a file distribution request to the user terminal 2 through the server, wherein the file distribution request carries the attribute of the file, the attribute comprises a uniform resource location system (uniform resource locator, URL for short) of the file in the server, and the user terminal 2 downloads the file from the server according to the URL after receiving the file distribution request and stores the file according to other contents in the attribute. Alternatively, the URL may be fed back to the user terminal 1 after the server receives the file uploaded by the user terminal 1.
When the file is transmitted in a Multimedia (MEDIA) manner, the user terminal 1 sends a file distribution request to the user terminal 2 through the server, the file distribution request carries the attribute of the file, the user terminal 2 returns a response message to the user terminal 1 through the server after receiving the file distribution request, the user terminal 1 sends the file to the user terminal 2 after receiving the response message, and the user terminal 2 stores the received file according to the attribute carried in the file distribution request.
However, when the user terminal 1 transmits a plurality of files to the user terminal 2, whether the files are transmitted by HTTP or MEDIA, the user terminal 1 needs to transmit a file distribution request once for each file, and the signaling overhead is large.
Fig. 3 is a second application scenario diagram provided by the present application. The application scenario shown in fig. 3 is a group file distribution scenario. Group file distribution refers to a user terminal sending files to all user terminals except the user terminal in the group where the user terminal is located. In fig. 3, the user terminals that transmit the file are represented by user terminal 1, the group in which user terminal 1 is located is represented by group a, the other user terminals in group a than user terminal 1 are represented by user terminals 2 to N, and user terminal 1 interacts with user terminals 2 to N through a server. In the scenario shown in fig. 3, the user terminal 1 is also called a transmitting terminal, and the user terminals 2 to N are all called receiving terminals.
Referring to fig. 4, in the present MCData specification, when the ue 1 transmits a certain file to the ues 2 to N, the method comprises the following steps:
When the file is transmitted by a hypertext transfer protocol (Hypertext Transfer Protocol, HTTP), the user terminal 1 firstly uploads the file to the server, then sends a file distribution request to the server, the file distribution request carries the identification of the group A and the attribute of the file, the attribute comprises a uniform resource location system (uniform resource locator, URL for short) of the file in the server, after receiving the file distribution request, the server analyzes the file distribution request from the group management server according to the identification of the group A to obtain other user terminals except the user terminal 1 in the group A, namely the user terminal 2 to the user terminal N, sends the file distribution request to the user terminal 2 to the user terminal N, and after receiving the file distribution request, the user terminal 2 to the user terminal N downloads the file from the server according to the URL and stores the file according to other contents in the attribute. Alternatively, the URL may be fed back to the user terminal 1 after the server receives the file uploaded by the user terminal 1.
When the file is transmitted in a Multimedia (MEDIA) manner, the user terminal 1 sends a file distribution request to the server, the file distribution request carries an identifier of the group a and an attribute of the file, after receiving the file distribution request, the server analyzes the group a according to the identifier of the group a to obtain other user terminals except the user terminal 1, namely, the user terminals 2 to N in the group a, and sends the file distribution request to the user terminals 2 to N, after receiving the file distribution request, the user terminals 2 to N return a response message to the user terminal 1 through the server, and after receiving the response message, the user terminal 1 sends the file to the user terminals 2 to N. And the user terminals 2 to N store the received files according to the attributes carried in the file distribution requests.
However, when the user terminal 1 transmits a plurality of files to the user terminals 2 to N, the user terminal 1 needs to transmit a file distribution request once for each file, regardless of the file transmitted by the HTTP method or the file transmitted by the MEDIA method, and the signaling overhead is large.
It can be seen that, in either a one-to-one file distribution scenario or a group file distribution scenario, when the user terminal 1 needs to send a plurality of files, a file distribution request needs to be sent once for each file, which results in a large signaling overhead and a waste of resources.
Considering that the reason why the signaling overhead is large is that the transmitting terminal needs to transmit a file distribution request once for each file, one important role of the file distribution request is to inform the receiving terminal of the attribute of the file to be transmitted by the transmitting terminal. With the method and the device as the access point, the application provides that the file distribution request is added into the attribute of all files to be transmitted by the transmitting terminal, so that the receiving terminal can receive a plurality of files at one time after receiving the file distribution request. Compared with the mode that a file distribution request needs to be sent once for each file, the method saves signaling overhead.
Specific embodiments of the present application will be described in detail below with reference to specific examples. The following embodiments may be combined with each other, and the same or similar concepts or processes may not be described in detail in some embodiments. Embodiments of the present application will be described below with reference to the accompanying drawings.
Example 1
In the scenario shown in fig. 1, fig. 5 is a schematic flow chart of a first embodiment of a file distribution method provided by the present application, and as shown in fig. 5, the file distribution method provided by the present embodiment includes:
s501, when the transmitting terminal needs to transmit a plurality of files to the receiving terminal, the transmitting terminal generates a file distribution request. The file distribution request includes: the ID of the terminal and the attributes of the plurality of files are received.
Alternatively, the file in this embodiment may be a picture.
In a possible implementation manner, the transmitting terminal may determine that multiple pictures need to be transmitted to the receiving terminal in the following scenario:
Referring to fig. 6, after a user opens a chat interface with a friend a after developing any social software on a sending terminal, and makes a clicking operation shown in fig. 6 on the chat interface, the sending terminal displays a selection interface, where the selection interface includes options such as album, shooting, video call, and the like. Under the condition that the user selects the album, the user terminal displays the pictures in the album, after the user selects a plurality of pictures, the sending button is clicked, and at the moment, the sending terminal can determine that the plurality of pictures need to be sent to the user terminal corresponding to the friend A. The transmitting terminal may further generate a file distribution request, where the file distribution request includes an ID of the user terminal corresponding to the user a and attributes of the plurality of pictures selected by the user.
The attributes of the plurality of files are described below:
The file distribution request carries attributes of a plurality of files, and each attribute of the files comprises a load (Payload) attribute of the file and a Metadata (Metadata) attribute of the file.
Referring to fig. 7, the Payload attribute of the file includes: load coding, load attribute length, load sequence number, and load attribute content. In the art, load encoding may be represented using Payload IEI, load attribute length may be represented using Length of Payload contents, load sequence number may be represented using Sequence of Payload, and load attribute content may be represented using Payload contents. The load code may occupy one byte, the load attribute length may occupy two bytes, the load sequence number may occupy one byte, and the number of bytes occupied by the load attribute content is related to Length of Payload contents. The load attribute content includes: load type and specific load content.
Referring to fig. 8, metadata attributes of a file include: metadata encoding, metadata attribute length, metadata sequence number, and metadata attribute content. Metadata encoding may be represented using METADATA IEI, metadata attribute length may be represented using Length of Metadata contents, metadata sequence number may be represented using Sequence of Metadata, and metadata attribute content may be represented using Metadata contents, as is known in the art. Metadata encoding may occupy one byte, metadata attribute length may occupy two bytes, metadata sequence number may occupy one byte, and metadata attribute content may be related to number of bytes Length of Metadata contents. The metadata attribute content includes: file name, file date, file description, file size, etc.
In fig. 7 and 8, ott 1 represents the first byte, ott 2 represents the second byte, and so on, each byte having 8 bits.
S502, the sending terminal sends a file distribution request to the server.
S503, the server determines the receiving terminal according to the ID of the receiving terminal.
S504, the server sends a file distribution request to the receiving terminal.
In one possible implementation manner, the server directly uses the user terminal corresponding to the received ID as a receiving terminal, and sends the file distribution request to the user terminal.
S505, the receiving terminal sends a response message to the server.
In one possible implementation manner, after receiving the file distribution request, the receiving terminal may display a file receiving reminder first, and after receiving a touch operation for confirming that the file is received by the user, send a response message to the server. The method combines the receiving willingness of the user, and the sending terminal can not send the file to the receiving terminal under the condition that the user does not want to receive the file, so that network resources are saved, and meanwhile, the use experience of the user is improved.
In a possible implementation manner, the receiving terminal may display the file receipt reminder in the following manner:
As shown in fig. 9, the receiving terminal may display the dialog box shown in fig. 9 to ask the user whether to agree to receive the file, if the user clicks yes, the receiving terminal sends a response message to the server, if the user clicks no, the receiving terminal does not send a response message to the server, and since the sending terminal sends the file after receiving the response message, the sending terminal does not send the file to the receiving terminal if the user clicks no, thereby saving network resources.
S506, the server sends a response message to the sending terminal.
S507, the sending terminal sends the first file to the server.
S508, the server forwards the first file to the receiving terminal.
S509, the receiving terminal stores the first file according to the attribute of the first file.
It should be noted that: as shown in fig. 5, similar steps are performed for the second file, the third file, and … n-th file. Such as: after the sending terminal sends the first file, the second file is sent to the server, the server further forwards the second file to the receiving terminal, and the receiving terminal stores the second file according to the attribute of the second file after receiving the second file.
Specifically, referring to fig. 7 and 8, after receiving the first file, the receiving terminal searches for the load attribute with the load serial number of 1 from the load attributes of each file, uses the load attribute as the load attribute of the first file, and similarly searches for the metadata attribute with the metadata serial number of 1 from the metadata attributes of each file, and uses the metadata attribute as the metadata attribute of the first file. And storing the first file according to the load attribute content in the load attribute with the load serial number of 1 and the metadata attribute content in the metadata attribute with the metadata serial number of 1.
Similarly, after receiving the second file, the receiving terminal searches the load attribute with the load serial number of 2 from the load attributes of each file, uses the load attribute as the load attribute of the second file, and similarly searches the metadata attribute with the metadata serial number of 2 from the metadata attribute of each file, and uses the metadata attribute as the metadata attribute of the second file. And storing the second file according to the load attribute content in the load attribute with the load serial number of 2 and the metadata attribute content in the metadata attribute with the metadata serial number of 2. And so on for subsequent files.
It should be noted that: the above numbers of loads are represented by numbers 1,2, etc. merely as an example, and may be represented by other forms, which are not limiting to the present application. According to the file distribution method provided by the embodiment, under a one-to-one distribution scene, the file distribution request is added to the attributes of all files to be transmitted by the transmitting terminal, so that after the receiving terminal receives the file distribution request, the receiving terminal knows that a plurality of files to be transmitted by the transmitting terminal exist, and after receiving the plurality of files, the receiving terminal stores each file according to the attributes carried in the file distribution request. Compared with the mode that a file distribution request needs to be sent once for each file, the method saves signaling overhead.
It should be noted that: the above-described S501 to S509 describe in detail a distribution method when a plurality of files transmitted by the transmitting terminal are files transmitted by the MEDIA method. If the plurality of files sent by the sending terminal are files transmitted in the HTTP manner, the user terminal 1 may upload the plurality of files to the server, and the server feeds back URLs of the plurality of files in the server to the sending terminal, where the sending terminal sends, to the receiving terminal, a file distribution request through the server, where the file distribution request carries attributes of each file, where each attribute of the file includes a load (Payload) attribute of the file and a Metadata (Metadata) attribute of the file, and the load (Payload) attribute includes a corresponding URL, and in particular, the URL may be carried in the load attribute content in fig. 7. After receiving the file distribution request, the receiving terminal downloads the first file from the server according to the URL in the load attribute content with the load serial number of 1, and stores the first file according to other information in the load attribute content with the load serial number of 1 and the metadata attribute content with the metadata serial number of 1. And so on for subsequent files.

Under the condition that the user selects the album, the user terminal displays the pictures in the album, after the user selects a plurality of pictures, the sending button is clicked, and at the moment, the sending terminal can determine that the plurality of pictures need to be sent to the user terminals corresponding to other members in the group A. The transmitting terminal may further generate a file distribution request including the ID of the group a and the attributes of the plurality of pictures selected by the user.
S1002, a sending terminal sends a file distribution request to a server.
S1003, the server determines the receiving terminal according to the ID of the group.
In one possible implementation manner, the group management server maintains the correspondence between the group ID and the user terminal, and after receiving the file distribution request, the server searches the user terminal corresponding to the ID carried by the file distribution request from the group management server. And taking other user terminals except the sending terminal in the user terminals corresponding to the ID carried by the file distribution request as receiving terminals.

Such as: after the sending terminal sends the first file, the second file is sent to the server, the server further forwards the second file to the receiving terminal, and the receiving terminal stores the second file according to the attribute of the second file after receiving the second file.
The specific storage manner refers to the above embodiment, and this embodiment is not described herein.
In the file distribution method provided in this embodiment, in a group file distribution scenario, a file distribution request is added to attributes of all files to be transmitted by a transmitting terminal, so that after a plurality of receiving terminals receive the file distribution request, it is known that there are a plurality of files to be transmitted by the transmitting terminal, and after each receiving terminal receives the plurality of files, each file is stored according to the attributes carried in the file distribution request. Compared with the mode that a file distribution request needs to be sent once for each file, the method saves signaling overhead.
It should be noted that: in the group file distribution scenario, the above-described S1001 to S1009 describe in detail a distribution method when a plurality of files transmitted by the transmitting terminal are files transmitted by the MEDIA method. If the plurality of files sent by the sending terminal are files transmitted by the HTTP mode, the sending terminal can upload the plurality of files to the server first, and the server feeds back the URLs of the plurality of files in the server to the sending terminal. The sending terminal then sends a file distribution request to the server, the file distribution request carrying the ID of the group and the attributes of the respective files, each file's attributes including a load (Payload) attribute of the file and Metadata (Metadata) attribute of the file, the load (Payload) attribute in turn including a corresponding URL, which may be specifically carried in the load attribute content in fig. 7. After receiving the file distribution request, the server determines the receiving terminal according to the ID of the group. And then transmits a file distribution request to the receiving terminal. After receiving the file distribution request, the receiving terminal downloads the first file from the server according to the URL in the load attribute content with the load serial number of 1, and stores the first file according to other information in the load attribute content with the load serial number of 1 and the metadata attribute content with the metadata serial number of 1. And so on for subsequent files.
