The MEM Client communicates with the MEM Server using a link-oriented stateful protocol. The communication interfaces are MEM-1 and MEM-2. The implementation process of the embodiment of the present invention mainly relates to the improvement of the functions of the MEM Client and the MEM Server software.

The following is an example of the implementation of the mobile mail service on the MEM Server side and the MEM Client side by using the IMAP or the IMAP protocol-based extension protocol as the MEM-1 and MEM-2 interfaces.

The IMAP protocol is exchanged between the MEM Client and the MEM Server. The IMAP is established on the link of the Transmission Control Protocol (TCP), which is close to the air interface link on the mobile terminal side. The IMAP underlying network is carried over the mobile network or WiFi. Among the two communicating parties, the MEM Client acts as the IMAP client and the MEM Server acts as the IMAP server. IMAP is a stateful connection-oriented protocol. After logging in, the user is in a specific protocol state, for example, Authenticated state. IMAP can send instructions to the server in this state, in the client and service. During the idle period of communication, IMAP needs to be sent: noop command keeps the link, noop is an instruction name of IMAP protocol, and the link is "keep alive".

The MEM Client software described in the embodiments of the present invention includes but is not limited to a user interface (UI) module, a mailbox management module, a multi-purpose Internet Mail Extensions (MIME) codec module, and an IMAP ten-party stack. Module, Push information processing module. The UI module is used to provide user operation interfaces such as editing, displaying, and mailbox maintenance of the mail; the mailbox management module is used to complete mail management and access of the inbox, the outbox, etc.; the MIME codec module is used to complete the mail. Data encoding and decoding functions; IMAP protocol The module is used to complete the IMAP protocol client function; the Push information processing module is used to complete the email notification information from the ONF "push".

Method embodiment one:

A mobile email service processing method according to an embodiment of the present invention includes: after the MEM Server determines that the link between the MEM client and the MEM Client is abnormally interrupted, the temporary information of the MEM Client is retained within a certain period of time, wherein the temporary information After the link is restored, the MEM Client communicates with the MEM Server. The temporary information may include, but is not limited to, protocol status information of the MEM Client, for example, the current status of the IMAP protocol.

Further, a first timer may be set, wherein the duration of the temporary information retained by the MEM server is controlled by setting the first timer. In other words, the MEM Server can add a timer function. The period of the timer is the length of the temporary information related to the MEM Client when a MEM Client is abnormally interrupted, and the temporary information such as the protocol status of the MEM Client is retained within the duration. Within this duration, if the MEM Client logs in again, subsequent communication is continued in accordance with temporary information such as the saved protocol status.

Through this embodiment, a processing method for the mobile email service when the link is abnormally interrupted by the MEM Server is provided, and the function of establishing the temporary record information with the client in the memory area is improved by the MEM Server, and the MEM is improved together with the improvement of the MEM Client. The client maintains continuity requirements when the bearer network is temporarily interrupted.

Method Embodiment 2:

FIG. 2 is a flowchart of a method for processing a mobile email service according to an embodiment of the present invention. As shown in FIG. 2, another method for processing a mobile email service according to an embodiment of the present invention includes the following steps S202 to S204:

Step S202: When the link between the MEM Server and the MEM Client is abnormally interrupted, for example, the underlying network is temporarily interrupted, to ensure the continuity of the user experience, the MEM Client may continue to run the MEM Client program, that is, does not exit; retain protocol status information and protocol events. , for example, the association The event may be receiving mail or sending mail, etc., so that when the link is restored, subsequent communication with the MEM Server may be performed according to the retained protocol state information and protocol events, and the current UI may be maintained.

Step S204, the MEM Client sends a link reestablishment request to the MEM Server. Thereafter, if a link between the mobile email server and the mobile email client is established, the MEM Client sends a login request to the MEM Server and carries the login information therein.

That is to say, for the MEM Client, after the network is interrupted and restored within a certain period of time, the MEM Client automatically logs in. Specifically, after the MEM Client detects that the IMAP link is interrupted, the timer can be started to re-link, and when the access network signal is restored, the re-link is successful. The MEM Client can also re-link after receiving the notification of the underlying network recovery, after which the MEM Client automatically logs in without the user having to re-enter the password and other information.

In step S204, the MEM Client sends a link reestablishment request to the MEM Server, including one of the following cases:

(1) A link re-establishment request is sent when the preset second timer expires. That is, the MEM Client of the mobile terminal can start a periodic link retry after the temporary interruption of the underlying network.

(2) After receiving the link recovery notification, the MEM Client sends a link reestablishment request. That is, after the temporary failure of the underlying network, the MEM Client of the mobile terminal can automatically re-establish the link with the MEM Server after receiving the notification of the underlying network recovery.

(3) The MEM Client sends a link reestablishment request when it detects that the network carrying the link is available. It should be noted that, according to the agreement with the MEM Server in advance, the MEM Client may carry or not carry the login information of the MEM Client in the above link reestablishment request, including the account and password of the MEM Client, for example, if the interrupt duration does not reach the threshold, If you do not need login information, you can link. If the interruption time reaches the threshold, you need to carry the login information to link.

With this embodiment, the MEM client is provided to the mobile email industry when the link is abnormally interrupted. The processing method. In order to ensure the seamless user experience of the MEM Client, the user interface can maintain the original user interface content without exiting the MEM Client during the network interruption time. For example, when the user browses the contents of the inbox, a temporary network interruption occurs. Then, the content of the interface remains unchanged. At this time, if the MEM Client performs a network exchange request with the MEM Server, for example, receiving an email, the interface is The information prompt of the network interruption is given, and the content of the interface after the prompt can be kept consistent with before the interruption.

The following is a method for maintaining the continuity of the MEM Server service described in the embodiment of the present invention in combination with the function improvement of the MEM Client and the MEM Server.

Step 1. The MEM Client of the mobile terminal logs in (login) to the MEM Server. The MEM-1 and MEM-2 interfaces between the MEM Client and the MEM Server are IMAP protocols, and the air interface bearer network close to the mobile terminal side may be Global System for Mobile Communications (GSM), code division multiple access ( CDMA (Code Division Multiple Access), Wideband Code Division Multiple Access (WCDMA), etc., or wireless local area such as WiFi, Worldwide Interoperability for Microwave Access, Metropolitan area network.

Step 2: After the user logs in, some operations of the mailbox and the mail can be performed without loss of generality. It is assumed that the protocol state of the user on the IMAP server is Authenticated. Thereafter, the underlying bearer network is temporarily interrupted. 3 is a schematic diagram of an upper layer service interruption caused by an interruption of an access network signal of a mobile terminal according to an embodiment of the present invention. As shown in FIG. 3, an IMAP/TCP link of a communication network between the MEM Client and the MEM Server is interrupted, where The communication network can be one of the following: WiFi, GSM, CDMA, WCDMA.

Step 3: When a network interruption occurs, the MEM Client does not exit, retains the protocol status information and the protocol event, and can maintain the current UI unchanged. The MEM Client starts the timer to perform the link operation between the reconstruction and the MEM Server, that is, the above steps. S202. Step 4: After detecting that the link with a certain client is abnormally interrupted, the server starts to control the temporary information of the client to a certain time interval.

Step 5: During a certain period of time, the mobile terminal recovers from the access network signal. At this time, the MEM Client link heavy chain is successful, the IMAP link is restored, and the MEM Client can automatically log in again. In this step, for the temporary interruption, the client can automatically log in by saving the login name and password in the buffer, that is, the above step S204.

Step 6: The MEM Server receives the login request of the user, retrieves the temporary interrupt MEM Client record in the memory, cancels the timer of the record after the search, and "connects" the temporary information saved in the record to the new link to continue. Communication.

Step 7: The MEM Client resumes the user operation and completes the MEM business continuity.

It should be noted that the present invention uses the IMAP protocol as an interface between MEM-1 and MEM-2, but the method for maintaining MEM Server service continuity described in the present invention is applicable to a client-server based on other protocols such as SMTP. The model's mobile mail system, for example, the MEM-1 interface is based on the Simple Mail Transfer Protocol (SMTP) and the MEM-2 based IMAP protocol.

The foregoing embodiment is applicable to the problem of temporarily interrupting the upper MEM service caused by the temporary interruption of the access network, and is applicable to solving the MEM service interruption caused by the handover of the multimode mobile terminal between different access networks.
