Description

一种双网双待终端进行通讯的方法和装置 Method and device for communicating by dual network dual standby terminal

技术领域 Technical field

本发明涉及移动通讯领域，尤其涉及一种双网双待终端进行通讯的方法和装置。背景技术 The present invention relates to the field of mobile communications, and in particular, to a method and apparatus for communicating between dual-network dual-standby terminals. Background technique

随着国内 3G网络建设逐步展开，三大移动通讯运营商都正式步入了 3G 时代。然而由于在当前 3G网络的建设初期以及接下来的一段发展期内， 3G 网络的覆盖水平相比已经经过了十几年不断优化和完善的 2G 网络，无论是覆盖的广度（ 2G网络几乎覆盖我国全部的自然村落 )还是覆盖的深度（如室内、地下室和地铁等）都存在较大差距，因而各大运营商也都不约而同的将 2G和 3G双网长期共存作为自己的运营目标和策略。***更是提出了 "不换卡、不换号、不需要登记"的三不原则以及清一色的时分同步码分多址（ Time Division-Synchronous Code Division Multiple Access, TD-SCDMA )/GSM (全球移动通信***）双模单待定制手机终端来推广和运营自己的 TD-SCDMA 3G网络。 With the gradual development of domestic 3G network construction, the three major mobile communication operators have officially entered the 3G era. However, due to the coverage level of 3G networks in the initial stage of the current 3G network construction and the next development period, the 2G network has been optimized and improved for more than ten years, regardless of the breadth of coverage (2G network covers almost China) All the natural villages) or the depth of coverage (such as indoors, basements and subways) have large gaps, so the major operators also have long-term coexistence of 2G and 3G dual networks as their operational goals and strategies. China Mobile has proposed the "three-non-principle of not changing cards, not changing numbers, and not requiring registration" and the time division of Synchronous Code Division Multiple Access (TD-SCDMA)/GSM (Global Mobile communication system) Dual-mode single-standby customized mobile terminal to promote and operate its own TD-SCDMA 3G network.

但是这种 "2、 3G网络共存" 、 "TD-SCDMA /GSM双模单待终端定制" 的策略在现实运营中却遇到了难题。一方面，由于现有的 "2、 3G双模切换" 策略，导致手机终端重选频繁，耗电严重，通话掉话，上网断流，甚至脱网等异常故障时有发生，用户体验较差；另一方面又由于现有的 3G 网络覆盖质量还远不如 GSM网络，导致用户对 TD-SCDMA网络信心不足。网络的问题导致了终端的困局，而终端的困局反过来又放大了网络的问题。 However, this "2, 3G network coexistence" and "TD-SCDMA / GSM dual-mode single-standby terminal customization" strategy has encountered difficulties in real-life operations. On the one hand, due to the existing "2, 3G dual-mode switching" strategy, mobile terminal re-selection is frequent, power consumption is serious, call drop, Internet disconnection, and even off-network abnormal faults occur, and the user experience is poor. On the other hand, because the existing 3G network coverage quality is far less than the GSM network, the user's confidence in the TD-SCDMA network is insufficient. The problem of the network has led to the dilemma of the terminal, and the dilemma of the terminal has in turn amplified the problem of the network.

也正是用户对 TD-SCDMA网络和 TD-SCDMA终端状态的不信任，一方面出现了 GSM网络超负荷运行，且大量的 GSM资源被数据业务占用；另一方面，也导致了 TD-SCDMA的网络利用率在很低的水平上，网络资源被严重浪费， TD-SCDMA网络发展也被严重制约。发明内容 It is also the user's distrust of the state of the TD-SCDMA network and the TD-SCDMA terminal. On the one hand, the GSM network is overloaded, and a large amount of GSM resources are occupied by the data service; on the other hand, it also leads to TD-SCDMA. At a very low level of network utilization, network resources are seriously wasted, and the development of TD-SCDMA networks is also severely constrained. Summary of the invention

本发明的较佳实施方式下文中将结合附图对本发明的实施例进行详细说明。需要说明的是，在不冲突的情况下，本申请中的实施例及实施例中的特征可以相互任意组合。 Preferred embodiment of the invention Embodiments of the present invention will be described in detail below with reference to the accompanying drawings. It should be noted that, in the case of no conflict, the features in the embodiments and the embodiments in the present application may be arbitrarily combined with each other.

本发明的基本思想是，针对 TD-SCDMA 网络带宽较大，适合数据业务 ( PS业务，即分组业务）；而传统的 2G网络网优工作积累较多，对语音等 2G业务支持较好的特点，在 2/3G双网双待终端上 CS (电路）业务优选 2G 网络，次选 3G网络，数据业务优选 3G网络，次选 2G网络。 The basic idea of the present invention is that the bandwidth of the TD-SCDMA network is large and suitable for data services (PS services, ie, packet services); while the traditional 2G network network has more accumulated work, and better support for 2G services such as voice. On the 2/3G dual-network dual-standby terminal, the CS (circuit) service prefers the 2G network, the secondary 3G network, the data service prefers the 3G network, and the secondary 2G network.

具体地，当所述双网双待终端的用户发起 PS业务，或者为 CS业务中的可视电话业务时，若 3G 网络信号满足信号强度的条件，则所述双网双待终端选择通过 3G网络进行通讯，否则，选择通过 2G网络进行通讯； Specifically, when the user of the dual-network dual-standby terminal initiates a PS service, or is a videophone service in the CS service, if the 3G network signal satisfies the condition of the signal strength, the dual-network dual-standby terminal selects to pass the 3G. The network communicates, otherwise, it chooses to communicate through the 2G network;

当所述双网双待终端的用户发起除可视电话业务以外的 CS 业务时，若 When the user of the dual-network dual standby terminal initiates a CS service other than the videophone service,

2G网络的 CS域资源饱和，则所述双网双待终端选择通过 3G网络进行通讯，否则，选择通过 2G网络进行通讯。 If the CS domain resource of the 2G network is saturated, the dual-network dual-standby terminal selects to communicate through the 3G network; otherwise, the communication is selected through the 2G network.

其中，可视电话业务虽然^ ^于 CS电路域的业务，由于必须通过 3G网络进行业务承载，所以当用户发起可视电话业务时，需要选择 3 G网络。 Among them, although the videophone service is in the CS circuit domain, since the service must be carried over the 3G network, when the user initiates the videophone service, the 3G network needs to be selected.

上述满足信号强度的条件是指，网络的信号强度可承载相关业务（即所发起的业务）。具体实现时，可以是当网络的信号强度大于指定门限值时，判断满足信号强度的条件。 The above condition for satisfying the signal strength means that the signal strength of the network can carry related services (i.e., services initiated). In a specific implementation, when the signal strength of the network is greater than a specified threshold, the condition for satisfying the signal strength may be determined.

上述 2G网络的 CS域资源是否饱和的信息可以由网络侧通过信令告知所述双网双待终端。另外，在本发明中，还可釆用如下方式对所发起的 PS业务进行调整，包括： The information about whether the CS domain resource of the 2G network is saturated may be notified to the dual-network dual standby terminal by the network side by signaling. In addition, in the present invention, the initiated PS service can also be adjusted in the following manner, including:

1、所述双网双待终端通过 3G网络进行通讯的过程中，当所述双网双待终端监测到当前 3G网络的信号强度减弱到无法承载所述 PS业务时，则所述双网双待终端先建立 2G网络的 2G数据链路，再将所述 PS业务对应的分组数据协议（ Packet Data Protocol, PDP )数据链路切换到所述 2G数据链路； In the process of the dual-network dual-standby terminal communicating through the 3G network, when the dual-network dual-standby terminal detects that the signal strength of the current 3G network is weak enough to be unable to carry the PS service, the dual-network dual Waiting for the terminal to first establish a 2G data link of the 2G network, and then switching a Packet Data Protocol (PDP) data link corresponding to the PS service to the 2G data link;

2、所述双网双待终端使用 2G数据链路进行 PS业务时，当监测到 3G网络的信号强度增强到可承载所述 PS业务时，则所述双网双待终端先建立 3G 网络的 3G数据链路，再将所述 PS业务对应的 PDP数据链路切换到所述 3G 数据链路。 2. When the dual-network dual-standby terminal uses the 2G data link to perform the PS service, when the signal strength of the 3G network is enhanced to be able to carry the PS service, the dual-network dual-standby terminal first establishes the 3G network. a 3G data link, and then switching the PDP data link corresponding to the PS service to the 3G Data link.

具体实现时，可以是双网双待终端判断当前 3G 网络的信号强度，若小于等于指定门限值，则判定无法发起所述 PS业务或承载所述 PS业务，若大于等于指定门限值，则判定可承载所述 PS业务。当然，上述三种情况所使用的指定门限值可以相等，也可以不等。 In a specific implementation, the dual-network dual-standby terminal may determine the signal strength of the current 3G network. If the threshold is less than or equal to the specified threshold, it may be determined that the PS service cannot be initiated or the PS service is carried. If the threshold is greater than or equal to the specified threshold, Then it is determined that the PS service can be carried. Of course, the specified thresholds used in the above three cases may be equal or unequal.

上述先建立 2G网络的 2G数据链路，再将 PDP数据链路切换到该 2G数据链路，以及，先建立 3G网络的 3G数据链路，再将 PDP数据链路切换到该 3G数据链路的好处是，可以实现数据链路的无缝不间断切换，用户不会感知到链路切换的过程。 The foregoing establishes a 2G data link of the 2G network, then switches the PDP data link to the 2G data link, and first establishes a 3G data link of the 3G network, and then switches the PDP data link to the 3G data link. The advantage is that the seamless and uninterrupted switching of the data link can be realized, and the user does not perceive the process of link switching.

上述 3G网络可以是 TD-SCDMA网络、宽带码分多址（ Wideband Code The above 3G network may be a TD-SCDMA network or a wideband code division multiple access (Wideband Code)

"不换卡、不换号、不登记" '三不原则，，需要同时支持 2G的 SIM卡以及 3G的（ U ) SIM卡，这项技术目前在 2/3G双模单待手机上已经大量使用，这里不做介绍。 "Do not change cards, do not change numbers, do not register" "Three non-principles, you need to support both 2G SIM cards and 3G (U) SIM cards. This technology is currently available on 2/3G dual-mode single-standby phones. Use, do not introduce here.

4、动态选网协调模块，是实现 "双网同时注册； PS业务及或者 CS的可视电话业务优选 3G网络，次选 2G网络，除可视电话业务以外的 CS业务优选 2G网络，次选 3G网络" 动态选网策略的关键模块，同时该模块也肩负着 (U)SIM卡模块、 2G无线通讯模块以及 3G无线通讯模块三者之间的协调和配合。具体功能如下： 4. Dynamic network selection coordination module is to realize "double network simultaneous registration; PS service and CS videophone service prefer 3G network, secondary 2G network, except for videophone service, CS service is preferred 2G network, secondary selection 3G network "Key module of dynamic network selection strategy, and the module also shoulders coordination and cooperation between (U)SIM card module, 2G wireless communication module and 3G wireless communication module. The specific functions are as follows:

1 )对 3G无线通讯子模块负责监测的 3G网络信号强度进行响应，并按如下策略对 PS域数据业务进行调度： 1) Respond to the 3G network signal strength monitored by the 3G wireless communication sub-module, and schedule the PS domain data service according to the following strategy:

今当 3G无线通讯子模块监测到所处 3G网络信号强度不足以支撑终端发起相关数据业务时， "动态选网协调模块" 能协调 2G无线通讯子模块激活 2G网络的 PS域分组数据业务链路来承载相关业务。今当终端正在使用默认的 3G网络进行数据业务过程中，所处位置的网络信号变弱至不足以支撑相关业务正常进行时， "动态选网协调模块" 通知 2G无线通讯模块建立 2G网络的 2G数据链路， 2G数据链路建立完成后，将相关 PDP数据链路切换到 2G无线通讯子模块负责的 2G数据链路上，以延续相关业务的正常进行。 When the 3G wireless communication sub-module detects that the 3G network signal strength is insufficient to support the terminal to initiate related data services, the "dynamic network selection coordination module" can coordinate the 2G wireless communication sub-module to activate the PS domain packet data service link of the 2G network. To carry related business. Now when the terminal is using the default 3G network for data service, when the network signal at the location becomes weak enough to support the related services, the "dynamic network selection coordination module" notifies the 2G wireless communication module to establish 2G of the 2G network. After the data link is established, the related PDP data link is switched to the 2G data link of the 2G wireless communication sub-module to continue the normal operation of the related services.

今当终端正在使用 2G数据链路进行数据业务过程中，所处位置 3G网络信号变强并恢复至足以支撑相关数据业务正常进行时， "动态选网协调模块" 通知所述 3G无线通讯模块建立 3G网络的 3G数据链路， 3G数据链路建立完成后，负责将相关 PDP数据链路切换回 3G数据链路。 When the terminal is using the 2G data link for data service, when the location 3G network signal becomes strong and recovers enough to support the related data service, the "dynamic network selection coordination module" notifies the establishment of the 3G wireless communication module. After the 3G data link of the 3G network is established, the related PDP data link is switched back to the 3G data link.

2 )根据 2G网络的 CS域资源情况，按照如下策略协调终端与 2G的 CS 域通讯还是与 3G的 CS域通讯：在终端待机的情况下，网络侧可通过发送信令给终端，告知 CS域资源是否饱和的信息， 2G无线通讯模块将该信息发送给 "动态选网协调模块" ，当 2G网络的 CS域资源饱和时， "动态选网协调模块" 选择 3G网络发起 CS业务；当 2G网络的 CS域资源不饱和时， "动态选网协调模块" 选择 2G 网络发起 CS业务。 2) According to the CS domain resources of the 2G network, coordinate the terminal to communicate with the 2G CS domain or the 3G CS domain according to the following policy: In the case that the terminal is in standby, the network side can send information to the terminal to inform the CS domain whether the resource is saturated. The 2G wireless communication module sends the information to the "dynamic network selection coordination module", and the CS domain resource of the 2G network. When saturated, the "dynamic network selection coordination module" selects the 3G network to initiate the CS service; when the CS domain resource of the 2G network is not saturated, the "dynamic network selection coordination module" selects the 2G network to initiate the CS service.

3 )协调两个无线通讯子模块对同一张 (U)SIM卡实现数据访问控制和共享。 3) Coordinating the two wireless communication sub-modules to implement data access control and sharing for the same (U)SIM card.

今当 (U)SIM卡模块挂接在 3G无线通讯模块侧时， "动态选网协调模块" 为 2G无线通讯模块提供访问 (U)SIM卡数据信息的代理服务功能。 Now when the (U)SIM card module is attached to the 3G wireless communication module side, the "Dynamic Network Selection Coordination Module" provides the proxy service function for accessing the (U)SIM card data information for the 2G wireless communication module.

今当 (U)SIM卡模块挂接在 2G无线通讯模块上时， "动态选网协调模块" 为 3G无线通讯模块提供访问 (U)SIM卡数据信息的代理服务功 fj匕。 Now when the (U)SIM card module is attached to the 2G wireless communication module, the "Dynamic Network Selection Coordination Module" provides the 3G wireless communication module with the proxy service function for accessing the (U)SIM card data information.

今当 (U)SIM卡模块同时挂接 2G和 3G两个无线通讯模块时， "动态选网协调模块" 对两个无线通讯模块访问 (U)SIM卡提供控制和管理功能。 Now when the (U)SIM card module is connected to two 2G and 3G wireless communication modules at the same time, the "dynamic network selection coordination module" provides control and management functions for the two wireless communication module access (U)SIM cards.

"动态选网" 的 "2、 3G双网双待单（U ) SIM卡终端" 在开机时， 2G 无线通讯模块负责完成终端在 2G 网络 CS和 PS域的注册， 3G无线通讯模块负责完成终端在 3G网络 CS和 PS域的注册。不同于传统终端， "动态选网，，的 "2、 3G双网双待单（U ) SIM卡终端，，进行数据业务优选 3G网络，进行语音业务优选 2G网络，如图 2所示。 "2, 3G dual-network dual standby single (U) SIM card terminal" of "dynamic network selection" At startup, the 2G wireless communication module is responsible for completing the registration of the terminal in the CS and PS domain of the 2G network, and the 3G wireless communication module is responsible for completing the terminal. Registration of CS and PS domains in 3G networks. Different from the traditional terminal, the "dynamically selected network", "2, 3G dual-network dual-standby (U) SIM card terminal, the data service is preferred to the 3G network, and the voice service is preferred to the 2G network, as shown in Figure 2.

只有当 2G 网络繁忙资源不足时（如春节群发短信或如人口高度密集的情况下呼叫困难等），终端才根据网络侧下发的指令通过 "动态选网协调模块" 选择 3G网络，发起语音业务。 Only when the 2G network has insufficient busy resources (such as the text message in the Spring Festival group or the call is difficult in the case of a dense population), the terminal selects the 3G network through the "dynamic network selection coordination module" according to the instructions issued by the network side to initiate the voice service. .

只有当 3G无线通讯模块侦知当前的 3G网络信号异常时，终端才通过"动态选网协调模块" 选择 2G网络，发起数据业务。 Only when the 3G wireless communication module detects that the current 3G network signal is abnormal, the terminal selects the 2G network through the "dynamic selection network coordination module" to initiate data service.

需要说明的是，在数据业务进行过程中，为了避免让用户感知链路切换的过程，需要在切换前，预先在另一侧网络建立相应的数据链路，再切断当前数据链路，以实现数据链路的无缝不间断切换。 It should be noted that, in the process of data service, in order to avoid letting the user perceive the process of link switching, it is necessary to establish a corresponding data link on the other side of the network before switching, and then cut off the Pre-data link for seamless, uninterrupted switching of data links.
