Description

Message status setting method and CPM business server

Technical field

The embodiments of the present invention relate to communication technologies, and in particular, to a message state setting method and a CPM service server. Background technique

The Open Mobile Alliance (OMA) is dedicated to deploying Push to talk Over Cellular (PoC), Instant Message (IM), and Internet Protocol (IP) messages. Mobile data service specifications such as Converged Internet Protocol Message (CPM). To provide a better business experience for users in heterogeneous environments, the OMA CPM specification provides users with a variety of media types (text, picture, voice, video) for message delivery, session establishment, and network storage.

The CPM standard defines two servers: CPM service server and CPM storage server. Users also have two clients: Session Initiated Protocol (SIP)-based CPM client and Internet Message Access Protocol (Internet Message Access Protocol). , referred to as IMAP) client, the two are not necessarily online at the same time. When a message arrives at the service server, the CPM service server sends a message to the terminal and/or the CPM message storage server according to user settings and the like. Typically, IMAP clients are only online when the terminal synchronizes with the CPM message store server and stores messages to the CPM message store server. According to the requirements of the CPM, when a message arrives at the CPM service server, the CPM service server sends a message to the terminal and/or the CPM message storage server according to user settings and the like. Due to the difference in user terminal performance and user settings, the CPM service server does not send all messages to the user terminal, nor does it store all messages to the CPM storage server. In the case that the CPM service server simultaneously sends the received message to the CPM storage server and the user terminal, if the read status of the message is stored in the CPM storage server, The read status of the message stored in the CPM storage server may be inconsistent with the status of the user terminal regarding the message. Summary of the invention

The embodiment of the invention provides a message state setting method and a CPM service server, which are used to solve

The reading status of the message stored in the CPM storage server is inconsistent with the user terminal's read status of the message.

An aspect of the present invention provides a method for setting a message state, including:

Receiving a message; determining that the message needs to be submitted to a storage server, sending a message storage request including the message to the storage server; determining that the message needs to be sent to a user terminal, and sending the message to the user terminal;

Receiving a receiving response returned by the user terminal, determining that a message corresponding to the receiving response is stored in the CPM storage server, and determining, according to the receiving response returned by the user terminal, a reading state of a message corresponding to the received response is Read, sending a message state modification request to the CPM storage server, wherein the read state of the message in the message state modification request is read.

An aspect of the present invention provides a CPM service server, including:

a receiving module, configured to receive a message; a message storage requesting module, configured to determine that the message needs to be submitted to a CPM storage server storage, and send a message storage request including the message to the CPM storage server;

a sending module, configured to determine that the message needs to be sent to a user terminal, and send the message to the user terminal;

The receiving module is further configured to receive a receiving response returned by the user terminal, and the state modifying requesting module is configured to receive a receiving response returned by the user terminal, and determine that the CPM storage server stores a response corresponding to the receiving response. And determining, according to the receiving response, that a read status of the message corresponding to the received response is read, and storing the service to the CPM The device sends a message state modification request, and the read state of the message in the message state modification request is read.

One aspect of the present invention provides a message state setting method and a CPM service server. When the CPM service server determines that a new message needs to be submitted to the CPM storage server, the message is sent to the CPM storage server. After the CPM storage server receives the message that does not indicate the read status, the CPM storage server defaults that the read status of the message is unread. If the CPM service server needs to send the message to the user terminal, if the read status of the message determined according to the receiving response returned by the user terminal is read, the CPM service server sends a message status modification request to the CPM storage server. Modifying the read status of the message in the CPM storage server according to the receiving response request returned by the user terminal. Thus, the read status of the message stored in the CPM storage server is consistent with the receiving status of the message by the user terminal. The CPM storage server can be prevented from transmitting a message that the user terminal has successfully received to the user terminal, which saves resources. It also avoids the user terminal repeatedly receiving the read message and improving the user experience.

Another aspect of the present invention provides another method for setting a message state, including:

Receiving a message; determining that the message needs to be submitted to the CPM storage server and transmitting the message to the user terminal, identifying a read status of the message as read; sending a message storage request to the CPM storage server, and reporting to The user terminal sends the message; the message storage request includes the message and the read status of the message; receiving the received response returned by the user terminal, and determining the message according to the received response returned by the user terminal The read status is unread, and a message status modification request is sent to the CPM storage server, and the read status of the message in the message status modification request is unread.

Another aspect of the present invention provides another CPM service server, including:

a receiving module, configured to receive a message, a determining module, configured to determine that the message needs to be submitted to the CPM storage server, and needs to send the message to the user terminal, and identify a read status of the message as a read message storage request module, Sending a message storage request to the CPM storage server, where the message storage request includes the message and a read status of the message; a module, configured to send the message to the user terminal, the receiving module is further configured to receive a receiving response returned by the user terminal, and a state modification requesting module, configured to determine, according to the receiving response returned by the user terminal, The read status of the message corresponding to the received response is unread, and the message status modification request is sent to the CPM storage server, where the read status of the message is unread.

Another message state setting method and a CPM service server provided by another aspect of the present invention, when the CPM service server needs to submit the message to the CPM storage server and needs to send the message to the user terminal, the CPM service server will The read status is identified as read, and the read status of the message carried when the server message storage request is stored to the CPM is read, causing the CPM storage server to store the read status of the message. And the CPM service server sends a message state modification request to the CPM storage server according to the read state of the message determined by the receiving response returned by the user terminal, according to the read state of the message in the message storage request, according to the user terminal The returned receive response request modifies the read status of the message in the CPM storage server. Thus, the read status of the message stored in the CPM storage server is consistent with the read status of the message by the user terminal.

Another aspect of the present invention provides a method for setting a message state, including:

Receiving a message; determining that the message needs to be submitted to a CPM storage server for storage, buffering the message; determining that the message needs to be sent to a user terminal, transmitting the message to the user terminal, and receiving a receiving response returned by the user terminal Determining that a message corresponding to the received response is buffered, identifying a read status of the cached message corresponding to the received response according to the received response returned by the user terminal; and transmitting a message storage request to the CPM storage server, The message storage request includes the cached messages and the read status of each message.

Yet another aspect of the present invention provides a CPM service server, including:

a receiving module, configured to receive a message, a cache module, configured to determine that the message needs to be submitted to a CPM storage server, and to cache the message, and a sending module, configured to determine that the message needs to be sent to the user terminal, to the user terminal Sending the message; receiving module, for receiving a receiving response returned by the user terminal; a status identifying module, configured to determine that a message corresponding to the received response is cached, and to identify a read status of the cached message corresponding to the received response according to the received response returned by the user terminal And a message storage requesting module, configured to send a message storage request to the CPM storage server, where the message storage request includes the cached message and a corresponding read state of each message.

According to still another aspect of the present invention, a message state setting method and a CPM service server are provided. After receiving a message, the CPM service server first caches a message that needs to be submitted to the CPM storage server, and the message that needs to be sent to the user terminal for the cache, CPM The service server identifies the read status of each cached message according to the received response returned by the user terminal. The CPM service server sends the cached messages and their read status to the CPM storage server for storage. Therefore, for messages that need to be submitted to the CPM storage server store and that need to be sent to the user terminal at the same time, the read status of the message stored in the CPM storage server is consistent with the read status of the message by the user terminal.

The technical solutions in the embodiments of the present invention are clearly and completely described in the following with reference to the accompanying drawings in the embodiments of the present invention. It is a partial embodiment of the invention, and not all of the embodiments. All other embodiments obtained by a person of ordinary skill in the art based on the embodiments of the present invention without any inventive effort are within the scope of the present invention.

In the embodiment of the present invention, the CPM service server may be a user subscription message service server, such as a CPM PF (Participation Function) Server, the CPM storage server may be a CPM Message Storage Server, and the user terminal may be a user message client. For example, CPM Client (CPM Client). The CPM service server and the CPM storage server may be devices such as computers, and the user terminals may be mobile phones, notebook computers, digital set top boxes, personal digital assistants, and the like. In the methods of the following embodiments, the steps performed by the CPM service server and the functions performed by each module of the CPM service server may be executed by a processor of a device such as a computer. Similarly, the steps performed by the CPM storage server and the functions performed by each module of the CPM storage server can also be performed by a processor of a device such as a computer.

FIG. 1 is a flowchart of Embodiment 1 of a message state setting method according to the present invention. As shown in Figure 1, this embodiment includes:

Step 11: The CPM service server receives the message.

When a user sends a new message to another user, the user acting as the sender sends a new message to the recipient user through the CPM service server.

Step 12: Determine that the message needs to be submitted to the CPM storage server store, and the CPM service server sends a message storage request including the message to the CPM storage server. The CPM service server may determine, according to the subscription information of the recipient user corresponding to the message, for example, according to the user's willingness to select whether the message received by the CPM service server is submitted to the CPM storage server, whether the message needs to be submitted to the CPM. Storage server storage. Normally, the user selects in the subscription information that "the user submits the received message to the CPM storage server when the user is online, and does not submit the received message to the CPM storage server when the user goes offline". Further, the user selects "the user does not submit the received message to the CPM storage server when the content of the message exceeds the preset value" in the subscription information.

When the CPM service server determines that the message needs to be submitted to the CPM storage server storage, it sends the message to the CPM storage server. After the CPM storage server receives the message storage request, if the message storage request does not indicate the read status of the message, the CPM storage server defaults the read status of the message to unread. After the CPM storage server stores the message and the read status of the message, it returns a storage response to the CPM business server.

Step 13: It is determined that the message needs to be sent to the user terminal, and the CPM service server sends the message to the user terminal.

The CPM service server may determine, according to the subscription information of the recipient user corresponding to the message, for example, according to the willingness of the user in the subscription information to select whether the message received by the CPM service server is sent to the user terminal, whether the message needs to be sent to and received. The user terminal of the party user. Normally, the user selects in the subscription information that "the user sends the received message to the user terminal when the user is online, and does not send the received message to the user terminal when the user goes offline". Further, the user selects "the user does not send the received message to the user terminal when the user is online but the user status is busy or do not disturb" in the subscription information.

Step 14: The CPM service server receives the receiving response returned by the user terminal, determines that the CPM storage server stores a message corresponding to the received response, and determines, according to the received response returned by the user terminal, that the read status of the message corresponding to the received response is Read, send a message status modification request to the CPM storage server, and the read status of the message in the message status modification request is read.

After the CPM service server sends the message to the user terminal, it receives the connection returned by the user terminal. Receive response. The CPM service server may determine, by the storage response returned by the cached CPM storage server, whether the message returned by the user terminal corresponding to the received response is stored in the CPM storage server. When it is determined that the message corresponding to the received response has been stored in the storage server, the CPM service server determines the read status of the response response corresponding message. When the receiving response indicates that the user terminal fails to receive, the CPM service server determines that the reading status of the receiving response corresponding message is unread; and the receiving response indicates that the user receives the success. The CPM service server determines that the read status of the response response corresponding message is read. When the read status of the response response corresponding message is read, the CPM service server sends a message status modification request to the CPM storage server, requesting to modify the read status of the message in the CPM storage server to read, so that the message is stored in the CPM storage server. The reading state is consistent with the reading status of the user terminal regarding the message.

The CPM service server can determine whether the message corresponding to the received response returned by the user terminal is stored in the CPM storage server. The following examples are as follows:

One method is to judge the message by assigning a unique identifier (MID) to the message through the CPM service server.

When the CPM service server determines that the message needs to be submitted to the CPM storage server, the message may be assigned a unique identifier (MID), and the message including the MID is carried in the message storage request and sent to the CPM storage server, and when the CPM storage server returns the storage response, The MID of the message is carried in the storage response. When it is determined that the message needs to be sent to the user terminal, the CPM service server sends the message including the MID to the user terminal. After the CPM service server sends the message to the user terminal, it receives the receiving response of the MID returned by the user terminal. The CPM service server searches for the cached storage response according to the MID in the received response, and if it finds a storage response including the MID in the received response, determines that the message corresponding to the received response has been stored in the storage server.

Another method is to: Determine the message by assigning a unique identifier (UID) to the message through the CPM storage server.

The CPM storage server return storage response may also include a unique identifier (UID) assigned by the CPM storage server for the message. Upon determining that the message needs to be sent to the user terminal, the CPM service server sends the message including the UID to the user terminal. CPM service server sends to the user terminal After the message is sent, the receiving response of the UID returned by the user terminal is received. The CPM service server searches for the cached storage response according to the UID in the received response. If the storage response including the UID in the received response is found, it is determined that the message corresponding to the received response is stored in the storage server.

In the embodiment of the present invention, if the CPM service server determines that the received message does not need to be submitted to the CPM storage server, whether the message needs to be sent to the user terminal, the CPM service server no longer reads the message during the receiving message phase. Carry out maintenance. In addition, if the CPM service server determines that the message needs to be submitted to the CPM storage server without sending the message to the user terminal, after the CPM service server sends a message storage request to the CPM storage server, the CPM service server receives the message phase, and the CPM service server The read status of the message is no longer maintained.

In the message state setting method of the embodiment of the present invention, when the CPM service server determines that the received message needs to be submitted to the CPM storage server, the message is sent to the CPM storage server. After the CPM storage server receives the message storage request, if the message storage request does not indicate the read status of the message, the CPM storage server defaults to reading the message as unread. If the CPM service server needs to send the message to the user terminal, if the read status of the message determined according to the receiving response returned by the terminal is read, the CPM service server sends a message status modification request to the CPM storage server. Modifying the read status of the message in the CPM storage server according to the receiving response request returned by the terminal. Therefore, the reading state of the message stored in the CPM storage server is consistent with the receiving state of the message by the user terminal, and the CPM storage server can be prevented from transmitting the message that the user terminal has successfully received to the user terminal, thereby saving resources. It also avoids the user terminal repeatedly receiving the read message, which improves the user experience.

FIG. 2 is a flowchart of Embodiment 2 of a method for setting a message state according to the present invention. This embodiment is a refinement flow of the corresponding embodiment of Fig. 1. As shown in FIG. 2, this embodiment includes:

Step la: The CPM service server receives the message.

For example, the CPM business server is a CPM PF Server, and the CPM PF Server receives a CPM.

Message, the CPM Message can be a Page Mode message, for example: SIP MESSAGE; Alternatively, the CPM Message can be a Large Mode message, for example: MSRP SEND MESSAGE. The full English name of MSRP is: Message Session Relay Protocol. Among them, SIP MESSAGE is a single transmission, and the number of bytes sent each time is limited, only 13022 bytes can be sent at a time. MSRP SEND MESSAGE is sent over a dedicated channel, and there is no limit to the number of bytes sent each time.

Step 2a: The CPM service server determines whether the message needs to be submitted to the CPM storage server for storage.

The CPM service server may determine, according to the subscription information of the recipient user corresponding to the message, for example, according to the willingness of the user in the subscription information to select whether the message received by the CPM service server is submitted to the CPM storage server, whether the message is Need to submit CPM storage server storage. Normally, the user selects in the subscription information that "the user submits the received message to the CPM storage server when the user is online, and does not submit the received message to the CPM storage server when the user goes offline". Further, the user selects "the user does not submit the received message to the CPM storage server when the user is online but the content length of the message exceeds the user preset value" in the subscription information.

When the CPM service server determines that the message does not need to be submitted to the CPM storage server storage, directly execute step 5a, otherwise step 3a is performed.

Step 3a: When the CPM service server determines that the message needs to be submitted to the CPM storage server storage, it sends a message storage request including the message to the CPM storage server.

Step 4a: The CPM storage server stores the message according to the message storage request and returns a storage response to the CPM service server.

After the CPM storage server receives the message without identifying the read status, the CPM storage server defaults that the read status of the message is unread. Taking the CPM message storage server based on the IMAP protocol as an example, the message storage request may be an IMAP APPEND message. The IPM protocol-based CPM message storage server receives the message storage request. If the message carried in the message storage request does not identify the read status, the read status of the message is "/Recent" (indicating that the message is a message) or "/Unseen". (Indicating that the message was not read). Further, in step 4a, the storage response returned by the CPM storage server may further include a unique identifier assigned to the message when the CPM storage server stores the message.

Step 5a: The CPM service server determines whether the message needs to be sent to the user terminal. When the CPM service server determines that the message does not need to be sent to the user terminal, the receiving process of the message ends, otherwise step 6a is performed.

Step 6a: When the CPM service server determines that it needs to be sent to the user terminal, the message is sent to the user terminal.

When the CPM Service Server determines that it needs to be sent to the user terminal, it can assign an identifier (MID) to the message. The CPM service server may also assign an identifier (MID) to the message when it is determined to submit the received message to the CPM storage server, and determine that the message carrying the MID is sent to the user terminal when it is sent to the user terminal. The CPM service server sends the message to the user terminal. The CPM PF Server sends a SIP MESSAGE to the CPM Client or sends an MSRP SEND message.

Further, if the unique identifier (UID) assigned by the CPM storage server to the message is included in step 4a, the CPM service server also carries the UID when transmitting the message to the user terminal. When the CPM storage server synchronizes the message to the user terminal, in addition to synchronizing the message whose read status is "unread" to the user terminal, it also checks whether the message whose read status is "read" in the storage server is saved with the user terminal. Whether the messages are consistent, that is, the message consistency check is performed. If not,

The CPM storage server synchronizes the message inconsistent with the user terminal to the user terminal. Since the CPM storage server may not be able to recognize the MID, or the MPM is not included in the message stored by the CPM storage server, other auxiliary information and methods are needed to check the consistency of the message through the MID, so that the implementation complexity is high. When the message stored in the user terminal includes the UID, the consistency of the UID of the message can be used to determine whether the message saved by the user terminal is consistent with the message saved by the CPM storage server. Therefore, checking the UID can reduce the complexity of checking message consistency when the CPM storage server synchronizes messages to the user terminal.

Normally, the CPM storage server can automatically synchronize messages when the preset time arrives. To the user terminal; the CPM storage server can also synchronize the message to the user terminal according to the active request of the user terminal when the user goes online; the CPM storage server can also synchronize the message to the user terminal according to other preset regulations.

Step 7a: The user terminal returns a receiving response to the CPM service server.

For example, when the receiving response is 'ΌΚ', it indicates that the user terminal receives successfully; when the receiving response is "Error", it indicates that the user terminal receives the failure.

Step 8a: The CPM service server determines whether the message is stored in the CPM storage server. When the CPM service server determines that the message is stored in the CPM storage server, step 9 a is performed, otherwise the process ends.

The CPM service server can determine whether the message corresponding to the received response returned by the user terminal is stored in the CPM storage server through the storage response returned by the cached CPM storage server. For example, the CPM service server can look up the cached storage response according to the identifier (MID) assigned by the CPM service server carried in the response to the message. If a storage response corresponding to the MID is found, it is determined that the message has been stored in the CPM storage server. Further, if the storage response includes the CPM storage server as the unique identifier (UID) of the message, the CPM service server may also search for the cached storage response according to the UID carried in the received response, and if the storage response corresponding to the UID is found, Make sure the message is stored on the CPM storage server. In addition, there are various implementation methods for determining whether the message corresponding to the received response has been stored in the CPM storage server, and will not be enumerated.

Step 9a: When the message is stored in the CPM storage server, the CPM service server determines the read status of the message based on the received response.

Specifically, if the receiving response is 'ΌΚ', it indicates that the user terminal receives successfully, and the reading state of the message is read; if the receiving response is “Error”, it indicates that the user terminal fails to receive, and the reading state of the message is unread. .

Step 10a: The CPM service server determines whether the read status of the message determined according to the received response is unread. When the CPM service server determines that the read status of the message is unread according to the received response, the read status of the message in the storage server does not need to be modified, and the process ends. When the CPM service server determines that the read status of the message is read according to the received response, step l la is performed.

Step 11a: The CPM service server sends a message modification request to the CPM storage server according to the receiving response to determine that the read status of the message is read, and requests the CPM storage server to modify the read status of the message to read.

Step 12a: The CPM storage server changes the read status of the message to read according to the message modification request, and returns a modification response to the CPM service server. Then the process ends.

Taking the CPM PF Server and the IMAP protocol-based CPM message storage server as an example, the CPM PF Server sends an IMAP STORE to the IMAP protocol-based CPM message storage server, and the CPM message storage server modifies the read status of the message to Unseen (indicating that the message has been read) ). In the IMAP-based message field, when the user goes online, the IMAP-based CPM message storage server needs to notify the user of the number of unread messages and unread messages. Through the method provided in this embodiment, the unread mail notified by the message storage server to the user is a message that the CPM PF Server does not send to the user terminal (or is not successfully sent to the user terminal). Therefore, the reading status of the mail in the CPM message storage server based on the IMAP protocol is consistent with the reading status of the mail on the user terminal. In the prior art, after the CPM message storage server based on the IMAP protocol receives the message forwarded by the service server, if the service server does not identify the read status, the read status of the message is unread by default. Therefore, if the message stored in the CPM message storage server based on the IMAP protocol has been successfully sent to the user terminal during the session, the read status of the message stored in the CPM message storage server based on the IMAP protocol is still unread. Therefore, the reading status of the mail in the CPM message storage server based on the IMAP protocol is inconsistent with the reading status of the mail on the user terminal, so that the CPM message storage server based on the IMAP protocol still needs to go to the user terminal when the user goes online again. Sending a message or email that has been successfully received by the user terminal not only causes waste of resources, but also makes the user repeatedly receive and affect the user experience.

Further, if the storage response of the CPM storage server is included in the storage service in step 4a The unique identifier assigned to the message is further included in the message modification request sent by the CPM service server to the storage server in step 11a, and the unique identifier assigned by the CPM storage server to the message. The CPM storage server can modify the read status of the message after finding the message according to the unique identifier of the message.

After transmitting the received message to the user terminal, the CPM service server requests the CPM storage server when determining that the read status of the message is unread according to the receiving response returned by the user terminal when determining that the message has been stored to the CPM storage server. Modify the reading status of the message. After the CPM service server sends the received message to the user terminal and determines that the message is not stored to the CPM storage server, the CPM service server does not have to maintain the read status of the message during the message receiving phase. Similarly, after the CPM service server submits the received message to the CPM storage server, if the message does not need to be sent to the user terminal, the CPM service server does not have to maintain the read status of the message during the message receiving phase.

FIG. 3 is a flowchart of Embodiment 1 of another method for setting a message state according to the present invention. The difference between this embodiment and FIG. 1 or FIG. 2 is that, in FIG. 1 or FIG. 2, when the CPM service server sends a message to the CPM storage server, the message is sent directly to the user terminal regardless of whether the message needs to be sent to the user terminal. To the CPM storage server, the CPM storage server defaults to reading the message as unread. In this embodiment, before sending the message to the CPM storage server, the CPM service server also considers whether it needs to send to the user terminal to the user terminal, and identifies the read status of the message, and sends a message indicating the read status to the CPM. Storage server. As shown in FIG. 3, this embodiment includes:

Step 31: The CPM service server receives the message.

Step 32: determining that a message needs to be submitted to the CPM storage server and sending a message to the user terminal, the CPM service server identifies the read status of the message as read, sends a message storage request to the CPM storage server, and sends a message to the user terminal; message storage The request includes the read status of the message and the message.

The CPM service server may according to the subscription information of the recipient user corresponding to the message, for example, the root According to the willingness of the user in the subscription information to select whether the message received by the CPM service server is submitted to the CPM storage server, it is determined whether the message needs to be submitted to the CPM storage server for storage. Normally, the user selects in the subscription information that "the user submits the received message to the CPM storage server when the user is online, and does not submit the received message to the CPM storage server when the user goes offline". Further, the user selects "the user does not submit the received message to the CPM storage server when the user is online but the content length of the message exceeds the user preset value" in the subscription information.

Step 33: The CPM service server receives the receiving response returned by the user terminal, and the read status of the message determined according to the receiving response returned by the terminal is unread, and sends a message state modification request to the CPM storage server, where the message is in the message state modification request. The reading status is unread.

Specifically, if the receiving response is 'ΌΚ', it indicates that the user terminal receives successfully, and determines that the reading state of the message is read; if the receiving response is “Error”, indicating that the user terminal fails to receive, determining that the reading state of the message is unread.

In the message state setting method of the embodiment of the present invention, when the CPM service server needs to submit the message to the storage server and needs to send the message to the user terminal, the CPM service server identifies the read status of the message as read, in the CPM The storage server message storage request carries the read status of the message, so that the CPM storage server stores the read status of the message. And if the read status of the message determined according to the receiving response returned by the terminal is inconsistent with the read status of the message in the message storage request, the CPM service server sends a message status modification request to the CPM storage server, according to the receiving return by the terminal. Modify the read of the message in the CPM storage server in response to the request State. Therefore, the reading state of the message stored in the CPM storage server is consistent with the reading state of the message by the user terminal, which can prevent the CPM storage server from transmitting the message that the user terminal has successfully received to the user terminal, saving resources and improving the user experience. .

FIG. 4 is a flowchart of Embodiment 2 of another method for setting a message state according to the present invention. This embodiment is a refinement flow of the corresponding embodiment of FIG. 3. As shown in FIG. 4, this embodiment includes:

Step lb: The CPM Service Server receives the message.

Step 2b: The CPM service server determines whether the message needs to be submitted to the CPM storage server for storage, and determines whether the message needs to be sent to the user terminal.

The CPM service server may determine, according to the subscription information of the recipient user corresponding to the message, for example, according to the user's willingness to select whether the message received by the CPM service server is submitted to the CPM storage server, whether the message needs to be submitted to the CPM. Storage server storage. In general, the user selects in the subscription information that "the user submits the received message to the CPM storage server when the user is online, and does not submit the received message to the CPM storage server when the user goes offline". Further, the user does not submit the received message to the CPM storage server when the user is online but the content length of the message exceeds the user preset value in the subscription information.

Step 3b: When the CPM service server determines that the message needs to be submitted to the CPM storage server and needs to send the message to the user terminal, the CPM service server identifies the read status of the message as read.

Step 4b: The CPM service server determines that the message needs to be submitted to the CPM storage server but not When the message needs to be sent to the user terminal, the CPM service server sends the message to the CPM storage server. The CPM service server receives the storage response of the CPM storage server, and the process ends.

After receiving the message, the CPM storage server defaults to reading the message as unread, stores the message and the read status of the message, and returns a storage response to the CPM service server after storage.

When the CPM service server determines that the message does not need to be submitted to the CPM storage server but needs to send the message to the user terminal, step 6b is directly executed.

Step 5b: The CPM service server sends a message storage request including the message and the read status of the message to the CPM storage server, and the CPM storage server stores the message and returns a storage response.

Step 6b: The CPM service server sends the message to the user terminal, and receives the receiving response returned by the user terminal.

Further, if the stored response in step 5b includes a unique identifier (UID) assigned by the CPM storage server for the message, the CPM service server in step 6b also carries the UID of the message when transmitting the message to the user terminal. When the CPM storage server synchronizes the message to the user terminal, in addition to synchronizing the message whose read status is "unread" to the user terminal, it is also necessary to check whether the message in the storage server whose read status is "read" is related to the user terminal. Whether the saved messages are consistent, that is, the message consistency check is performed. If not, the CPM storage server synchronizes the message with the user terminal to the user terminal. Since the CPM storage server may not be able to recognize the MID, or the MPM is not included in the message stored by the CPM storage server, when the MID is used to check the consistency of the message, other auxiliary information and methods are needed, so that the implementation complexity is high. When the message stored in the user terminal includes the UID, the consistency of the UID of the message may be used to determine whether the message saved by the user terminal is consistent with the message saved by the CPM storage server. Therefore, by checking the UID, the complexity of checking the message consistency when the CPM storage server synchronizes the message to the user terminal can be reduced.

Normally, the CPM storage server can automatically synchronize messages to the user terminal when the preset time arrives. The CPM storage server can also be activated according to the user terminal when the user goes online. Request to synchronize the message to the user terminal; the CPM storage server can also synchronize the message to the user terminal according to other preset rules.

Step 7b: The CPM service server determines whether the message is stored in the CPM storage server. If it is already stored on the CPM storage server, go to step 8b, otherwise it ends.

The CPM service server can determine whether the message corresponding to the received response returned by the user terminal is stored in the CPM storage server through the storage response returned by the cached CPM storage server. For example, the CPM service server may look up the cached storage response according to the identifier (MID) assigned by the CPM service server carried in the response to the message. If the storage response corresponding to the MID is found, it is determined that the message is stored in the CPM storage server. Further, if the storage response includes the CPM storage server as the unique identifier (UID) of the message, the CPM service server may also search for the cached storage response according to the UID carried in the received response, and if the storage response corresponding to the UID is found, determine The message is already stored on the CPM storage server. In addition, there are various ways to determine whether the message corresponding to the receiving response has been stored in the CPM storage server, and no longer.

Step 8b: When the message is stored in the CPM storage server, the CPM service server determines the read status of the message based on the received response.

Step 9b: The CPM service server determines whether the read status of the message determined according to the received response is unread. If it is unread, go to step 10b, otherwise the process ends.

When the CPM service server determines that the read status of the message is read according to the received response, since the CPM storage server is requested to identify the read status of the message as read in step 3b, there is no need to modify the read status of the message in the CPM storage server. , the process ends.

Step 10b: When the CPM service server determines that the read status of the message is unread according to the received response, the CPM service server sends a message modification request to the CPM storage server, requesting the CPM storage server to send the message. The reading status is changed to unread. After that, the CPM service server receives the CPM storage server and returns a modification response, and the process ends.

FIG. 5 is a flowchart of still another embodiment of a message state setting method according to the present invention. This embodiment is adapted to batch processing of received messages by the CPM service server. As shown in FIG. 5, this embodiment includes:

Step 51: The CPM service server receives the message.

Step 52: Determine that the message needs to be submitted to the CPM storage server store, and the CPM service server caches the message.

Step 53: Determine that the message needs to be sent to the user terminal, and the CPM service server sends the message to the user terminal, and receives the receiving response returned by the user terminal.

The CPM service server may determine, according to the subscription information of the recipient user corresponding to the message, for example, according to the willingness of the user in the subscription information to select whether the message received by the CPM service server is sent to the user terminal, whether the message needs to be sent to the User terminal of the recipient user. Normally, the user selects in the subscription information that "the user sends the received message to the user terminal when the user is online, and does not send the received message to the user terminal when the user goes offline". Further, the user selects "the user does not send the received message to the user terminal when the user is online but the user status is busy or do not disturb" in the subscription information.

Step 54: Determine that a message corresponding to the received response is buffered, and identify a read status of the cached message corresponding to the received response according to the received response returned by the user terminal. Step 55: The CPM service server sends a message storage request to the CPM storage server, where the message storage request includes the cached messages and the read status of each message.

The CPM service server may send a message storage request to the CPM storage server when there are multiple messages or cached messages to be processed, such as when the cache space is full or the preset cache amount is reached.

After receiving the message, the CPM service server first caches the message that needs to be submitted to the CPM storage server. For the cached message that needs to be sent to the user terminal, the CPM service server identifies the read status of the cached message according to the received response returned by the user terminal. . The CPM service server sends the cached messages and their read status to the CPM storage server for storage. Therefore, for a message that needs to be submitted to the CPM storage server storage and needs to be sent to the user terminal at the same time, the reading state of the message stored in the CPM storage server is consistent with the reading state of the message by the user terminal, so that the CPM storage server can be avoided from being sent to the user. The terminal sends a message that the user terminal has successfully received, which saves resources and improves user resources.

FIG. 6 is a flowchart of still another embodiment 2 of a message state setting method according to the present invention. This embodiment is a detailed flow of the corresponding embodiment of Fig. 6. As shown in Figure 6. This embodiment includes:

Step lc: The CPM service server receives the message.

Step 2c: The CPM service server determines whether the message is submitted to the CPM storage server storage. If step 3c is performed, otherwise step 4c is performed.

Step 3c: The CPM service server caches messages to be submitted to the CPM storage server. After that, go to step 5c.

Step 4c: When it is determined that the message needs to be sent to the user terminal, the message is sent to the user terminal. After that, the process ends.

Step 5c: The CPM service server determines whether the message is sent to the user terminal. If step 6c is performed, otherwise step 11c is performed: that is, the CPM service server identifies the read status of the cached message as unread, and executes step 12c.

Step 6c: The CPM service server sends the message to the user terminal, and receives the user terminal. Receive response back.

Step 7c: The CPM service server determines whether a message corresponding to the received response is cached. If it is step 8c, the process ends.

The CPM service server can determine whether to cache a message corresponding to the received response returned by the user terminal by using the cached message. For example, the CPM service server searches for the cached message according to the identifier (MID) assigned by the CPM service server carried in the response, and if the message cached corresponding to the MID is found, it is determined that the message is cached. In addition, there are various implementation methods for judging whether the message corresponding to the received response has been stored in the CPM storage server, and will not be listed one by one.

Step 8c: The CPM service server determines whether the reception response indicates that the reception is successful. If it is, go to step 9c, otherwise go to step 10c.

Step 9c: The CPM service server identifies the read status of the message in the cache corresponding to the received response as read.

Step 10c: The CPM service server identifies the read status of the message in the cache corresponding to the received response as unread.

Repeat the above steps until the CPM service server's cache is full or has received a batch of batch processed messages, and then perform step 12c.

Step 12c: After sending the cached messages and the read status of each message to the CPM storage server, the CPM service server receives the storage response returned by the CPM storage server. Then the process ends.

With the method provided in this embodiment, the message that needs to be sent only to the user terminal does not need to be cached in the CPM service server; for the message that only needs to be submitted to the CPM storage server, the CPM service server identifies the read status of the cached message as unread. For need to submit to both The CPM stores the server and the message sent to the user terminal. After the CPM service server caches the message, the CPM service server identifies the read status of the message according to the received response returned by the user terminal.
