无线终端及其多SIM卡连接装置 Wireless terminal and a multi-SIM card connecting device

技术领域 FIELD

[0001] 本发明涉及无线终端技术领域,尤其涉及一种无线终端及其多SIM卡连接装置。 [0001] The present invention relates to a wireless terminal technology, and particularly relates to a wireless terminal and a multi-SIM card connecting device. 背景技术 Background technique

[0002] SIM卡(Subscriber Identity Module,用户识别卡)用于在无线终端上对用户身份和服务权限进行认证,无线终端通过与用户识别卡交互来建立与对应网络的连接并完成通信功能。 [0002] SIM card (Subscriber Identity Module, User Identity Module) card for authenticating the user identity and service permissions on the wireless terminal, the wireless terminal connected through the interaction with the user identification card corresponding to the network to establish and complete a communication function. 现有技术中,一个无线终端的基带芯片只能连接一个SIM卡,也就是说一个无线终端只能使用一个电话号码。 In the prior art, a wireless terminal baseband chip of a SIM card can be connected, that a wireless terminal can use a telephone number.

[0003] 在技术、市场和无线移动应用业务发展的共同驱动下,无线移动通信产业发展迅速,移动通讯产品已经成为人们日常工作、生活的必备品。 [0003] In the joint drive technology, marketing and business development of mobile wireless applications, wireless mobile communications industry has developed rapidly, mobile communication products have become the people's daily work and life of essential goods. 随着手机用户数不断增加,一个用户同时拥有两张以上便携式通讯装置的SIM卡的情形也越来越多。 With the situation growing number of mobile phone users, a user also has two SIM card more portable communication devices is also increasing. 例如一些需要经常两地工作的人群,为避免昂贵的异地漫游费用,通常会在两地各拥有一张本地的SIM卡,在不同的城市使用不同的SIM卡。 For example, some people need two often work, in order to avoid expensive roaming charges in different places, usually each have a local SIM card in two places, using different SIM cards in different cities. 频繁的更换SIM卡或者携带两部手机都非常麻烦。 Frequent replacement of SIM cards or carry two phones are very troublesome.

[0004] 针对这种需求,出现了可支持多个SIM卡的便携式通讯装置,如通过运用手机上的微处理控制单元(MCU)控制并转换两个用户识别卡内所包含的数据,通过手机的重新启动来选择使用任意一张SIM卡。 [0004] In response to this demand, there has been a portable communication device can support a plurality of SIM cards, control and convert the two data included in the subscriber identity card by using microprocessing control unit (MCU) on the phone, mobile phone restart choose to use any SIM card. 该方法不必用户手动换卡就可以实现双SIM卡的互换,却需要在切换SIM卡时关闭手机再重新启动手机,对于用户来说很不方便。 This method does not have to manually changing the card can be interchangeable dual SIM card, but need to turn off the phone when switching SIM card and restart the phone, very convenient for the user.

[0005] 公开号为US2006/0234693A1的美国专利申请提供了一种双卡双待手机。 [0005] U.S. Patent Application Publication No. US2006 / 0234693A1 provides a dual card is a dual standby mobile phone. 该手机可以在开机状态达到双卡的相互切换,而不需要关机,更不需要手动换卡。 The phone can achieve switching between the dual card is turned on, without the need to shut down, but does not require changing the card manually. 但是,该手机需要两套基带芯片及两套射频系统来分别对应两张SIM卡,使手机的成本上升且体积增加。 However, the handset requires two RF baseband chip and two systems respectively corresponding to two SIM cards, so that the cost rises and increases the volume of the phone.

[0006] 随着技术发展和市场的需求,现有技术中又出现了一个基带芯片连接两个或更多用户识别卡的方案,包括: [0006] With the development of technology and the market demand, the prior art has emerged to connect two or more subscriber identity card scheme a baseband chip, comprising:

[0007] (1)基带芯片内置多个用户识别卡切换模块。 [0007] (1) a plurality of baseband chip built-in switching module subscriber identification cards. 随着技术发展,某些基带芯片通过内置多用户识别卡切换模块的方式实现了一个基带芯片连接多个用户识别卡。 With technological development, some of the baseband chip of a baseband chip connecting a plurality of subscriber identification cards built by multiple subscriber identification cards mode switching module. 如公开号为CN201674672U的中国专利申请提供了一种手机控制电路及支持多卡的手机。 As Publication No. CN201674672U of Chinese patent application provides a control circuit and a cell phone to support multi-card phone. 所述手机控制电路包含有基带模块和片选控制模块。 The control circuit includes a phone module and a base band chip select control module. 基带模块包含有多个用户识别模块卡控制器,用来控制所耦接的多个用户识别模块卡;片选控制模块耦接于基带模块,用以提供多个协议实体,分别对应至多个用户识别模块卡控制器,其中当其中的一个协议实体建立通话或数据连线时,协议实体通知其他协议实体由第一状态改变为第二状态。 The baseband module includes a plurality of subscriber identification module card controller for controlling a plurality of subscriber identification module card coupled; chip select control module is coupled to baseband module for providing a plurality of protocol entities, respectively corresponding to the plurality of users when the SIM card controller, wherein when a protocol entity established call or data connection, notifies other protocol entity from the first protocol entity changes state to a second state. 此种解决方案集成度高, 生产制造方便,但其缺点是灵活性差,必须使用特定的基带芯片,扩展性差。 Such a solution is highly integrated, easy to manufacture, but its drawback is poor flexibility must use a specific baseband chip, poor scalability.

[0008] (2)增加专用的多用户识别卡切换模块。 [0008] (2) adding a dedicated multi-user identification card switching module. 现有的大量的基带芯片并没有内置用户识别卡切换模块,而应用这些基带芯片的系统同样也有多卡多待的需求,为此在这样的系统上需要增加专门的芯片来连接多SIM卡,如公开号为CN101217745A的中国专利申请提供了一种单套芯片实现的双卡双待手机,所述单芯片双卡双待手机包括天线、射频模块、基带处理模块、电源模块和两个SIM卡槽,所述的基带处理模块通过SIM接口跟一个同时连接两个SIM卡槽的电子开关相连,并通过片选控制电路对电子开关进行控制。 Large number of existing baseband chip not built subscriber identification card switching module, and the application of these baseband chip system also how the demand card multi-standby, for which in such a system need to add a special chip to connect multiple SIM card, as disclosed in Chinese Patent No. CN101217745A dual card application provides a single-chip implementation of the set of dual standby mobile phone, the single-chip dual card dual standby mobile phone includes an antenna, a radio frequency module, a baseband processing module, a power module and the two SIM cards slot, the baseband processing module via an interface with a SIM electronic switch connected simultaneously connected to two SIM card slot, and chip select control circuit controls the electronic switch. 从而在一套手机硬件上实现双卡同时待机。 In order to achieve the dual card standby at the same time on a mobile phone hardware. 但是,目前这样的专门芯片最多只能支持两路或三路SIM卡。 However, currently only supports up to two-way or three-way SIM card such specialized chips.

[0009] 针对市场上出现的无线终端四卡四待需求,现有技术有以下两种解决方案: [0009] For wireless terminal four Card Quad appear to be on the market demand, the prior art has the following two solutions:

[0010] 第一,参见图1所示,通过一个内置两个用户识别卡切换模块的基带芯片1与两个支持两路SIM卡的单芯片2级联,每个单芯片2与两张SIM卡相连,从而实现四卡四待的功能。 [0010] First, referring to FIG, by a subscriber identification card contains two baseband chip switching module supports two SIM cards 11 and two cascaded single-chip 2, and two each of the single chip SIM 2 card connected to perform the functions of the four cards to be four.

[0011] 第二,参见图2所示,通过一个无内置多用户识别卡切换模块的基带芯片1'与三个支持两路SIM卡的单芯片2级联,每个单芯片2与两张SIM卡相连,从而实现四卡四待的功能。 [0011] Second, referring to FIG. 2, through a built-in multi-user non-identification card switching baseband chip module 1 'and 2 supports three cascaded single-chip two SIM cards, and two each of the single chip 2 SIM card is connected, enabling function 4 card four standby.

[0012] 但是,上述两种方案存在以下缺点: [0012] However, the two above has the following disadvantages:

[0013] 1)为了实现四卡四待的功能,每个单芯片2都需要外围电路,从而图1所示的方案需要设计2个外围电路,图2所示的方案需要设计3个外围电路,从而外围电路比较复杂; [0013] 1) In order to implement the functions of the four cards to be four, each of the single-chip peripheral circuit 2 are required, so that the program shown in FIG. 1 requires two peripheral circuit design, the program shown in Figure 2 need to design the peripheral circuits 3 thereby the peripheral circuit is more complex;

[0014] 2)当在四张SIM卡中进行切换时,图1所示的方案需要1次内部命令和2次接口芯片命令,图2所示的方案需要3次接口芯片命令,从而所需命令较多,降低了处理效率; [0014] 2) When switching the four SIM card, the program shown in FIG. 1 requires a secondary internal command interface chip and the secondary command, the program shown in Figure 2 requires three command interface chip, such that the desired command more, reducing the processing efficiency;

[0015] 3)图1所示的方案需要两个单芯片2,图2所示的方案需要三个单芯片,从而增加了电路板的面积,提高了生产成本;当实现四卡四待以上的需求时,其所需要的芯片会更多,从而生产成本会进一步提高。 [0015] shown in Scheme 3) in FIG. 1 requires two single-chip 2, the program shown in Figure 2 requires three single-chip, thereby increasing the area of ​​the circuit board, production cost is increased; when the four cards to be to achieve four or more when demand, it will need more chips, which will further increase the cost of production.
