总体而言， 可以提供根据当前手机状态在移动多媒体广播与广播电视 之间切换的技术， 从而确保无论在不插 SIM卡还是插 SIM卡状态、 以及在 3G网络还是无网络的情况下， 用户都能够正常收看手机电视； 同时， 考虑 到移动通信网络下的手机电视能够为用户提供更加丰富多彩的业务， 因此 主要考虑优选移动通信网络下的手机电视， 只有在没有移动通信网络的情 况下才会切换到广播电视网络， 当重新搜索到移动通信网络后可以从广播 电视网络切回到移动通信网络。 并且， 用户在广播电视网络中收看广播电 视时， 为了避免影响用户收看， 在收看电视过程中不会打断用户， 可以在 用户停止收看本次电视节目后提示用户进行切换。  In general, it is possible to provide a technology for switching between mobile multimedia broadcasting and broadcast television according to the current state of the mobile phone, thereby ensuring that the user is in the state of not inserting the SIM card or inserting the SIM card, and in the case of the 3G network or no network. It is able to watch mobile TV normally; at the same time, considering that mobile TV under mobile communication network can provide users with more colorful services, it is mainly considered to optimize mobile TV under mobile communication network, only if there is no mobile communication network. Switching to the broadcast television network, when re-searching for the mobile communication network, it can be switched back to the mobile communication network from the broadcast television network. Moreover, when the user watches the broadcast television in the broadcast television network, in order to avoid affecting the user's viewing, the user is not interrupted during the television viewing process, and the user may be prompted to switch after the user stops watching the television program.
在具体应用中， 可以设置如图 1 所示的装置， 该装置包括： 网络状态 检测***、 界面提示***、 功能控制***和节目更新***， 其中的网络状 态检测***、 界面提示***和功能控制***可以设置于用户终端中。  In a specific application, a device as shown in FIG. 1 may be provided, the device comprising: a network state detection system, an interface prompt system, a function control system, and a program update system, wherein the network state detection system, the interface prompt system, and the function control system Can be set in the user terminal.
实际应用时， 网络状态检测***负责实时检测网络状态， 当检测到网 络状态后， 判断检测到的状态与之前的网络状态是否一致， 并在不一致时 分别通知界面提示***和功能控制***。 界面提示***负责与用户的交互， 接收用户的指令并且在接收到网络状态变化的通知后提示用户更新节目 单。 功能控制***主要是在接收到网络状态变化的通知后负责手机电视在 移动通信网络和广电网络之间进行切换， 如： 接收到网络状态变化的通知 后， 首先判断当前状态， 如果是紧急呼叫状态， 则设置当前的节目更新类 型为 0, 并且通知节目更新***更新节目； 如果是 3G网络， 则设置当前的 节目更新类型为 1 , 激活 PDP, 并在接收到 PDP激活成功的消息后通知节 目更新***更新节目。 节目更新***能够根据当前设置的节目更新类型搜 索不同频段， 并且将搜索结果反馈给界面提示***和功能控制***。 In actual application, the network state detection system is responsible for detecting the network state in real time. When the network state is detected, it is determined whether the detected state is consistent with the previous network state, and the interface prompting system and the function control system are separately notified when the network state is inconsistent. The interface prompting system is responsible for interacting with the user, receiving the user's instructions and prompting the user to update the program list after receiving the notification of the network status change. The function control system is mainly responsible for switching between the mobile communication network and the radio and television network after receiving the notification of the network state change, for example: after receiving the notification of the network state change, first determining the current state, if it is an emergency call state , the current program update type is set to 0, and the program update system is notified to update the program; if it is a 3G network, the current program update type is set to 1, the PDP is activated, and the program update is notified after receiving the message that the PDP activation is successful. The system updates the program. The program update system can search according to the currently set program update type. Cables are used in different frequency bands, and the search results are fed back to the interface prompt system and the function control system.
为了防止信号的抖动， 在网络状态检测***当中可以增加防抖动功能， 如： 当网络状态检测***检测到网络状态变化后， 设置一个定时器 （该定 时器可以临时设置， 也可以预先设置并在检测到网络状态变化后临时启 动）， 并在定时器超时后再次检测网络状态以确定近两次所检测到的网络状 态是否一致， 并在一致时更新节目单， 否则不执行更新节目单操作。  In order to prevent signal jitter, the anti-jitter function can be added in the network state detection system, such as: After the network state detection system detects the network state change, set a timer (this timer can be temporarily set, or can be preset and After the network status change is detected, it is temporarily started. After the timer expires, the network status is detected again to determine whether the detected network status is consistent twice, and the program list is updated when it is consistent. Otherwise, the program update operation is not performed. .
在进入手机电视时， 首先可以从网络状态检测***获取 SIM卡的状态 和网络状态， 如果无 SIM卡或者处于紧急呼叫状态， 则设置节目更新类型 为 0, 之后通知节目更新***更新节目； 如果处于 3G网络状态， 则设置节 目更新类型为 1 , 之后通知节目更新***更新节目。 另外， 也可以是在手机 电视应用启动之后， 当网络状态检测***检测到网络状态发生变化时启动 定时器， 在定时器超时后再次查询网络状态以确认网络状态是否发生变化， 如果网络状态由紧急呼叫状态变为 3G网络状态， 设置节目更新类型为 1 , 并且通知节目更新***更新节目；如果网络状态由 3G网络状态变为紧急呼 叫状态， 则设置节目更新类型为 0, 并且通知节目更新***更新节目。  When entering the mobile TV, the status and network status of the SIM card can be first obtained from the network status detection system. If there is no SIM card or in an emergency call state, the program update type is set to 0, and then the program update system is notified to update the program; In the 3G network state, the program update type is set to 1, and then the program update system is notified to update the program. In addition, after the mobile TV application is started, when the network status detection system detects that the network status changes, the timer is started, and after the timer expires, the network status is queried again to confirm whether the network status changes, if the network status is urgent The call status changes to the 3G network status, the program update type is set to 1, and the program update system is notified to update the program; if the network status changes from the 3G network status to the emergency call status, the program update type is set to 0, and the program update system is notified. program.
以上所述操作方式， 不仅可以应用于手机上， 也可以在含有手机电视 功能的数据网 SIM卡终端上使用； 无论是何种类型的用户终端， 只要能够 正确检测网络状态， 并在检测到网络状态发生变化时， 能够根据变化后的 网络状态在不同的手机电视信号网络之间 （如： 在移动多媒体广播与广播 电视之间）切换即可。 上述的具有自适应、 全自动特点的切换方式， 能够 令用户得到极佳的用户体验。  The above operation mode can be applied not only to a mobile phone but also to a data network SIM card terminal including a mobile TV function; no matter what type of user terminal, as long as the network status can be correctly detected and the network is detected When the status changes, it can be switched between different mobile TV signal networks (such as between mobile multimedia broadcast and broadcast TV) according to the changed network status. The above-mentioned adaptive, fully automatic switching mode enables the user to have an excellent user experience.

需要说明的是，所述的网络状态不仅包括上述的 3G网络状态和紧急呼 叫状态， 上述的 3G网络状态只是正常网络状态中的一种而已。 在实际应用 中， 正常网络状态可能还包括 2G等其它内容； 并且， 作为网络状态中的一 种， 无网络状态也是比较常见的。  It should be noted that the network state includes not only the foregoing 3G network state and the emergency call state, but the above 3G network state is only one of the normal network states. In practical applications, the normal network status may also include other content such as 2G; and, as one of the network states, no network status is also common.
下面， 例举三个具体应用时的实例， 以说明实现手机电视业务切换的 具体操作细节。  In the following, three specific application examples are illustrated to illustrate the specific operational details of implementing the mobile TV service switching.
实例 1 : 手机处于待机状态， 用户选择进入手机电视。  Example 1: The mobile phone is in standby mode, and the user chooses to enter the mobile TV.
这种情况下， 可以首先获取卡的状态， 如果未***卡， 设置当前节目 更新类型为 0, 再更新节目单。 如果***卡， 则获取当前网络状态， 如果为 紧急呼叫状态， 则设置当前节目更新类型为 0, 再更新节目单； 如果为 3G 网络状态， 则设置当前节目更新类型为 1 , 并激活 PDP, 再更新节目单。  In this case, you can first obtain the status of the card. If the card is not inserted, set the current program update type to 0, and then update the program list. If the card is inserted, the current network status is obtained. If it is an emergency call status, the current program update type is set to 0, and the program list is updated; if it is the 3G network status, the current program update type is set to 1, and the PDP is activated, and then Update the program list.
实例 2: 手机处于手机电视节目列表界面， 此时网络状态从紧急呼叫状 态变化为 3G网络状态。 这种情况下， 可以在接收到网络状态变化通知后， 根据该通知或当前 实际情况查询当前的网络状态， 如果是 3G网络状态、且与设置的节目更新 类型不对应， 则保存查询到的网络状态并启动定时器， 在定时器超时后再 一致， 则不进行后续操作； 否则， 可以创建等待提示框以提示用户， 并设 置节目更新类型为 1 , 激活 PDP, 在接收到 PDP激活成功的消息后重新更 新节目列表， 在接收到节目列表更新成功的消息后关闭提示框并显示节目 歹1 J表界面。 Example 2: The mobile phone is in the mobile TV program list interface, and the network status changes from the emergency call state to the 3G network state. In this case, after receiving the network status change notification, the current network status may be queried according to the notification or the current actual situation. If the status is 3G network and does not correspond to the set program update type, the queried network is saved. Status and start the timer. If the timer expires again, the subsequent operations are not performed. Otherwise, a wait prompt box can be created to prompt the user, and the program update type is set to 1, the PDP is activated, and the PDP activation success message is received. after re-update program list, a balloon was closed after receiving a program list update success message and displays the program table 1 J bad interface.
实例 3： 手机处于手机电视节目列表界面， 此时网络状态从 3G网络状 态变化为紧急呼叫状态。  Example 3: The mobile phone is in the mobile TV program list interface, and the network status changes from the 3G network status to the emergency call status.
这种情况下， 可以在接收到网络状态变化通知后查询当前的网络状态， 如果是紧急呼叫状态、 且与设置的节目更新类型不对应， 则保存查询到的 网络状态并启动定时器， 在定时器超时后再次获取网络状态。 如果再次获 取的所述网络状态与保存的所述网络状态不一致， 则不进行后续操作； 否 则， 可以创建等待提示框以提示用户， 并设置节目更新类型为 0, 去激活 PDP, 在接收到 PDP去激活成功的消息后重新更新节目列表， 在接收到节 目列表更新成功的消息后关闭提示框并显示节目列表界面。  In this case, the current network status may be queried after receiving the network status change notification. If it is an emergency call status and does not correspond to the set program update type, the queried network status is saved and the timer is started. Get the network status again after the timer expires. If the network state acquired again is inconsistent with the saved network state, no subsequent operations are performed; otherwise, a waiting prompt box may be created to prompt the user, and the program update type is set to 0, the PDP is deactivated, and the PDP is received. After deactivating the successful message, the program list is re-updated, and after receiving the message that the program list update is successful, the prompt box is closed and the program list interface is displayed.
由以上所述流程及实例可知， 本发明实现手机电视业务切换的流程简 图可以表示如图 6所示， 图 6所示流程包括以下步骤：  It can be seen from the above-mentioned processes and examples that the flow diagram of the mobile phone television service switching of the present invention can be represented as shown in FIG. 6.
