- FIG. 2 is a flowchart of a MEM service processing method according to an embodiment of the present invention. As shown in FIG. 2, the method includes the following steps S202 to S204:
- Step S202 When the mobile terminal switches from the source access network to the target access network, establish a new link with the MEM server on the target access network, and send a handover request for requesting network handover to the MEM server.
- the handover request may be a login request message, where the login request message carries information indicating handover, that is, the handover request may be merged with the request command of the login MEM Server, and the meaning of "switching" is represented by carrying a certain parameter.
- Information or by default, a MEM Client by MEM Server logs in as a "switch" request.
- the mobile terminal may be on the new link, that is, the link established based on the target access network; or the original link established on the source access network, that is, based on the upper MEM link established by the original access network.
- the MEM Server sends a handover request.
- Step S204 the MEM Server receives the foregoing handover request, switches to the new link, and continues to communicate with the mobile terminal on the new link according to the locally stored information about the MEM service of the mobile terminal.
- the foregoing related information includes: Protocol status information of the original link established on the source access network.
- the MEM Server retrieves the relevant information in the local buffer, and after the MEM Server communicates with the MEM Client on the new link, the MEM Server may disconnect from the MEM Client.

Or the client ID (Client ID), after receiving the request, the MEM Server determines that the request is a link switch request that has been logged in to the MEM Client according to a preset determination rule, and the MEM Server and the terminal follow the newly established MEM link. The information about the protocol status and other information is used for subsequent communication. This solves the problem that the MEM client needs to log in to the MEM server again after the current bearer network switchover, which will result in poor user experience, maintain the continuity of the MEM service, and improve the user experience.
- the following is an IMAP or IMAP-based extension protocol for the MEM-1 and MEM-2 interfaces.
- the protocol is an embodiment, and the implementation process of the present invention is described in detail.
- 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 improved software functions of MEM Client include: Adding a new switching control module or adding a manual switching interface.
- the handover control module is configured to complete automatic handover control between the mobile network and the WiFi.
- the switching control module obtains the signal energy value of the WiFi and the mobile network, and determines whether the MEM client needs to be notified of the handover operation by using a preset switching policy. If the handover policy is required, the handover is performed, and the handover is performed on the bearer network after the handover.
- the IMAP TCP link on the end, and re-login (login) carries the switch request information or function parameters through the login, for example, the Client ID, that is, the MEM Client ID.
- the manually switched operator interface provides user-operable options that allow the user to switch between the mobile network and the WiFi network at any time, as the network signal allows, ensuring that the MEM Client can be used seamlessly after switching.
- the user interface can maintain the original user interface content during network interruption time. For example, when a user browses the contents of the inbox, a switch occurs, and then the content of the interface remains unchanged. The auto-refresh feature of the mailbox is temporarily canceled or a message prompt is given, but the display content remains the same as before the interruption.
- the improved function of the MEM server is as follows:
- the login carries a parameter that can determine the meaning of the "handover".
- the parameter can be a client ID, that is, the above switching indication information is a client identity identifier (Client ID) information.
- Client ID client identity identifier
- the MEM Server can only establish a set of MEM links on the server as the judgment principle. After searching and matching, it is found that the client instance represented by the Client ID already exists. If it exists, the protocol status of the response in the buffer is temporarily Information is associated with the newly created MEM link.
- This parameter can also be a field carrying "switching" information, and the MEM Server determines whether to retrieve a match based on the field.
- the mobile terminal accesses the network.
- the method for maintaining the continuity of the MEM Server service described in the embodiment of the present invention includes the following steps 1 to 6:
- Step 1 The MEM Client logs in to the MEM Server through the WiFi bearer mode.
- the user can select a network type such as a WiFi network or a mobile network, for example, the terminal selects WiFi network access at this time; or automatically sets the selection.
- FIG. 3 is a schematic diagram of a MEM service switched from WiFi to a mobile network according to an embodiment of the present invention.
- the terminal switches from WiFi to the mobile network.
- the switching type is set according to a preset configuration, and the switching can be automatic switching or manual switching. The automatic switching is initiated by the switching control module, and the manual switching is initiated by the user manually operating the user interface.
- Step 3 The mobile terminal re-establishes an IMAP/TCP link on the switched target bearer network, and the MEM Client initiates a login request on the new link (ie, step S202), and carries related function parameters.
- the terminal can be dual standby or single standby. If it is dual standby, the MEM Client only needs to establish a new IMAP/TCP link directly. If it is a single standby, after the switch, the MEM Client needs to establish a new IMAP/TCP link after the terminal completes the mobile network access.
- Step 4 After receiving the login request, the MEM Server determines to perform retrieval according to the carried function parameter, matches the original user record, and completes the association between the newly established link and the original temporary data.
- Step 5 The MEM Client completes the handover process and resumes the user operation on the newly established link (ie, step S204 described above).
- Step 6 After the handover is completed, if the original link exists, the MEM Server actively disconnects the original IMAP link.
- a MEM service processing method in which a terminal is handed over from a WiFi network to a mobile network is implemented.
- the embodiment of the present invention takes the IMAP protocol as an interface between the MEM-1 and the MEM-2, but the method for maintaining the continuity of the MEM Server described in the present invention is applicable to the client-server model of the mobile mail system of other protocols.
- the MEM-1 interface is based on SMTP and MEM-2 is based on the IMAP protocol.

考虑到目前承载网络切换后, MEM Client往往需要重新登录 MEM Server会导致业务不连续等用户体验较差的问题,本发明实施例提供了一种 MEM业务处理方案, 多模移动终端在不同接入网之间切换时, MEM Client 在目标接入网上重新建立与 MEM Server之间的链路, 并向 MEM Server发 送带有切换请求的指令, 该指令可以与登录指令复合, 使得该 MEM Client 在 MEM Server 的临时信息转移到新建立的链路上继续通信, 即, MEM Server接收到该请求后, 可以在緩冲区检索匹配该 MEM Client相关记录, 并在新建立链路上按照原来链路的协议状态等临时信息继续后续的通信。 在切换完成后, MEM Server可以主动断开与 MEM Client原来的链接。 从 而可以保证 MEM Client进行网络切换后再次自动登录时仍能恢复以前的协 议状态等临时信息 , 可以达到 MEM Client无缝切换的用户体验效果。
需要说明的是, 在不沖突的情况下, 本申请中的实施例及实施例中的 特征可以相互组合。 下面将参考附图并结合实施例来详细说明本发明。
方法实施例
根据本发明的实施例, 提供了一种 MEM业务的处理方法, 使用 MEM 业务的移动终端至少支持源接入网和目标接入网。在移动终端上运行 MEM Client , MEM Client与 MEM Server采用面向链接的有状态的协议通信, 通 信接口为 MEM-1 和 MEM-2。 本发明实施例的实现过程主要涉及到 MEM Client与 MEM Server软件功能的改进。 下面将以 IMAP或基于 IMAP协议 的扩充协议为 MEM- 1、 MEM-2接口为实施例, 分别对 MEM Server侧和
MEM Client侧实现 MEM业务的处理过程进行描述。
MEM Client与 MEM Server之间通过 IMAP协议进行交互, IMAP建立 在传输控制协议(Transfer Control Protocol, TCP )链路之上, 靠近移动终 端侧的空口链路, IMAP底层网络通过移动网络或者 WiFi承载。 通信双方 中, MEM Client作为 IMAP客户端, MEM Server作为 IMAP服务端。 IMAP 为有状态的面向连接的协议, 用户登录后就处于某个特定的协议状态, 例 如 Authenticated状态, MEM Client可以向服务端发送该状态下允行的指令, 在客户端与服务端的通信空闲时段内, 需要发送 IMAP: noop指令保持链 路, 所述 noop为 IMAP协议的一个指令名, 作用为链路保活。
本发明实施例描述的 MEM Client软件包括但不限于用户界面 (User Interface, UI )模块、 邮箱管理模块、 MIME编解码模块、 IMAP协议栈模 块、 Push信息处理模块。 其中, UI模块用于提供邮件的编辑、 显示和邮箱 维护等用户操作界面; 邮箱管理模块用于完成收件箱、 发件箱等邮箱的邮 件管理和存取; 多用途网际邮件扩充协议 ( Multipurpose Internet Mail Extensions, MIME )编解码模块用于完成邮件数据的编码和解码功能; IMAP 协议模块用于完成 IMAP 协议客户端功能; Push信息处理模块用于完成 ONF"推送"过来的邮件通知信息。
图 2是根据本发明实施例的 MEM业务处理方法的流程图,如图 2所示, 该方法包括如下的步骤 S202至步骤 S204:
步骤 S202, 移动终端由源接入网向目标接入网进行切换时, 在目标接 入网上建立与 MEM Server之间的新链路, 并向 MEM Server发送用以请求 进行网络切换的切换请求。 该切换请求可以为登录请求消息, 其中, 登录 请求消息中携带有指示切换的信息, 也就是说, 上述的切换请求可以与登 录 MEM Server的请求指令合并,通过携带一定参数代表"切换"含义的信息, 或者由 MEM Server默认某一个 MEM Client第二次登录为"切换"请求。
其中, 移动终端可以在新链路, 即基于目标接入网所建立的链路; 或 者在源接入网上建立的原链路,即基于原来的接入网所建立的上层 MEM链 路上向 MEM Server发送切换请求。
步骤 S204, MEM Server接收上述切换请求, 切换到新链路, 并根据本 地保存的移动终端的 MEM业务的相关信息,在新链路上继续和移动终端进 行通信, 上述的相关信息包括: 移动终端在源接入网上建立的原链路的协 议状态信息。
具体地, 在 MEM Server接收切换请求之后, MEM Server在本地的緩 冲区检索相关信息 , 在 MEM Server在新链路上和 MEM Client进行通信之 后, 可以由 MEM Server断开与 MEM Client在源接入网上建立的原链路, 也可以由 MEM Client断开该原链路。
需要说明的是, 上述的源接入网和目标接入网可以包括但不限于如下 组合:
( 1 ) 源接入网为无线局域网, 即 WiFi网络, 目标接入网为移动网络。
( 2 )源接入网为移动网络, 目标接入网为无线局域网或者无线城域网。
( 3 ) 源接入网和目标接入网分別为两种不同的无线局域网。
通过本发明, 在多模移动终端在不同接入网之间切换的情况下, 通过 MEM Client向 MEM Server发送"切换"请求, 该切换请求中可以携带有能 够判别为"切换"信息的参数, 或者客户端标识( Client ID ), MEM Server在 接收到请求后, 根据预先设置的判定规则判断此请求为已经登录 MEM Client的链路切换请求, MEM Server与终端在新建立的 MEM链路上按照 保留的协议状态等信息进行后续的通信,解决了目前承载网络切换后, MEM Client需要重新登录 MEM Server会导致用户体验较差的问题,维持了 MEM 业务的连续性, 进而提高了用户体验。
下面以 IMAP或基于 IMAP协议的扩充协议为 MEM-1、 MEM-2接口
协议为实施例, 对本发明的实现过程进行详细描述。 本发明实施例的实现 过程主要涉及到 MEM Client与 MEM Server软件功能的改进。
其中, MEM Client改进的软件功能包括: 新增切换控制模块或者增加 手动切换的操作界面。
具体地,切换控制模块用于完成移动网络和 WiFi之间的自动切换控制。 切换控制模块获取 WiFi、 移动网络的信号能量值, 通过预先设置的切换策 略决定是否需要通知 MEM Client进行切换操作,如果经过切换策略判定后, 需要切换, 则在切换后的承载网上重新建立与服务端的 IMAP TCP链路, 并且重新登录(login ), 通过 login携带切换请求信息或者功能参数, 例如, Client ID, 即 MEM Client识别码。
手动切换的操作界面提供用户可操作的选项, 使得用户能够根据需要, 在网络信号允许的情况下, 随时在移动网络和 WiFi网络之间切换, 而保证 切换后 MEM Client能够无缝使用。
为了保证 MEM Client提供无缝的切换用户体验 , 用户界面在网络中断 时间, 可以保持原有的用户界面内容。 例如, 用户在浏览收件箱内容时, 发生切换, 那么, 此时界面内容保持原有数据不变。 邮箱自动刷新功能临 时取消或者给出信息提示, 但显示内容保持与中断前一致。
MEM Server改进的功能有: 判断 login时携带能够判断"切换"含义的 参数, 该参数可以为 Client ID, 即, 上述的切换指示信息为客户端身份标 识( Client ID )信息。 MEM Server根据一个 Client ID只能在服务端建立一 套 MEM链接为判定原则, 经过检索匹配发现 Client ID代表的客户端实例 是否已存在, 如果存在, 则将緩冲区中响应的协议状态等临时信息与新建 立的 MEM 链接相关联。 该参数也可以为携带"切换"信息的字段, MEM Server根据该字段决定是否检索匹配。
结合 MEM Client和 MEM Server的功能改进, 移动终端进行接入网络
切换情况下,实现本发明实施例描述的维持 MEM Server业务连续性的方法 包括如下的步骤 1至步骤 6:
步骤 1 , MEM Client通过 WiFi承载方式,登录( login )到 MEM Server。 在该步骤中, 根据终端具体情况, 通常 MEM Client在启动之前或之后, 用 户可以选定网络种类如 WiFi网络或者移动网络, 例如, 此时终端选择 WiFi 网络接入; 或者自动设置选定。
步驟 2,用户登录后,一般情况下,用户进行了邮箱和邮件的某些操作, 假定此时 MEM Client在 MEM Server即 IMAP服务端的协议状态是授权 ( Authenticated ) 状态。 图 3是根据本发明实施例的 MEM业务由 WiFi切 换到移动网络的示意图,如图 3所示,终端发生从 WiFi到移动网络的切换。 在该步骤中, 根据预先的配置设定切换种类, 切换可以为自动切换或者手 动切换。 自动切换由切换控制模块发起, 手动切换由用户手工操作用户界 面发起。
步骤 3 , 移动终端在切换后的目标承载网上重新建立 IMAP/TCP链路, MEM Client在新链路上发起 login请求(即, 上述的步骤 S202 ), 并携带相 关功能参数。 终端可以为 WiFi 双待机或者单待机, 如果为双待机, MEM Client只需要直接建立新的 IMAP/TCP链路即可。如果是单待机, 那么切换 后, MEM Client 需要在终端完成移动网络接入之后才能建立新的 IMAP/TCP链路。
步骤 4 , MEM Server接收到该 login请求后,根据携带的功能参数决定 进行检索, 匹配原有用户记录, 并完成新建立的链路与原有临时数据的关 联。
步骤 5 , MEM Client完成切换过程, 并在新建立的链路上恢复用户操 作 (即, 上述的步骤 S204 )。
步骤 6, 切换完成后, 如果原有链路存在, MEM Server主动断开原有
IMAP链路。
通过该实施例, 实现了终端由 WiFi网络切换至移动网絡的 MEM业务 处理方法。
需要说明的是, 以上步骤以 WiFi网络切换至移动网络为例, 该实施例 与移动网络切换到 WiFi网络的处理过程相似, 在此不再赘述。 本发明实施 例以 IMAP协议为 MEM- 1、 MEM-2之间的接口为例, 但本发明描述的维 持 MEM Server业务连续性的方法适用于其他协议的客户端 -服务器模型 的移动邮件***, 如 MEM-1接口基于 SMTP、 MEM-2基于 IMAP协议。
