离。 from. 随着CDMA (码分多址)移动通信的不断发展,其网络结构也不断发展,目前已经向全IP化、控制承载分离方向发展,CDMA2000 LMSD (遗留用户终端域)的网络结构示意图如图2所示。 With the CDMA (Code Division Multiple Access) mobile communication growing, evolving network structure thereof, has been to all IP-based, control bearer separating direction, CDMA2000 LMSD (legacy user terminal domain) network structure diagram in FIG. 2 Fig.

从图2可以看出,CDMA2000以后发展的方向为:全IP化以及承载控制分离。 As can be seen from Figure 2, the direction of the future development of CDMA2000: All-IP bearer and control the separation. 另外,由于以后各种电信网络之间的竟争主要是业务竟争,各种智能业务会层出不穷,这种智能业务一般有较强的交互性,需要用户按键输入信息。 In addition, because after all kinds of competition between the telecommunication network is mainly business competition, a variety of smart business are endless, this intelligent business generally have a strong interactive, user key input required information.

在图2所示的CDMA系统中,将用户的皿输入信息压缩在带内传输,再传递给网络中的另一个实体。 In the CDMA system shown in FIG. 2, the user input information compressed dishes in-band transmission, before being passed to another entity in the network. 该另一个实体完成这种带内音的检测并还原成上述用户的按键输入信息。 The completion detection of such another entity within the audio band is reduced to said user and key input information. 上述用户的按键输入信息的传输方式适用于基于标准的G.711的传输网络。 Transmission of said user key input information is applied to a standards-based transport network in G.711.

DTMF (双音多频信号)是电话系统中电话机与交换机之间的一种用户信令。 DTMF (dual tone multi-frequency signals) A user is the telephone system and the signaling between telephone switches. 当CDMA2000的网络结构IP化以后,在以IP传输来传输语音信号时, 一般会采用较大压缩率的编码格式,从而可能造成DTMF (双音多频)信号失真。 When IP-based CDMA2000 network structure, and when to transmit IP to transmit voice signals, encoding format generally uses greater compression ratio, which may result in DTMF (Dual Tone Multi-Frequency) signal distortion. 在这种情况下,如果还按照上述用户的按键输入信息的传输方式来传 In this case, if the further transmission in accordance with said user input information to transmit the key

输DTMF的按键输入信息,将导致DTMF的按键输入信息被错误地检测或失效,从而导致很多应用业务,比如电话银行等等在以后的CDMA2000 LMSD 等网络中无法应用。 DTMF key input information transmission, the information will result in DTMF key input to be erroneously detected or failure, resulting in many business applications, such as telephone banking and the like can not be applied in the future CDMA2000 LMSD peer network. 上述问题对CDMA2000 LMSD等网络而言是必须迫切解 For the above-mentioned problems CDMA2000 LMSD peer network is a solution must be urgently

CDMA2000 AII-IP核心网络系统将CDMA移动网络中的MSC网元拆分为M;SCe (移动软交换中心)和MGW (媒体网关)/MRFP (媒体资源功能处理器)两个核心网网元,MSCe和MGW/MRFP可完全替代传统的MSC功能, MSCe负责呼叫控制、移动性管理等功能,MGW/MRFP负责媒体承载功能。 CDMA2000 AII-IP core network to a CDMA mobile network system in the network element MSC is split into M; SCe (Soft Mobile Switching Center) and the MGW (Media Gateway) / MRFP (Multimedia Resource Function Processor) two core network element, MSCe and MGW / MRFP can completely replace the traditional MSC functionality, MSCe responsible for call control, mobility management functions, MGW / MRFP is responsible for media bearing. 传统语音业务可由IP传输替代TDM传输。 Traditional voice services by IP transport alternative to TDM transport.

以CDMA2000 LMSD网络为例,本发明所述方法的实施例的实现原理图如图3所示,具体处理过程的流程图如图4所示,包括如下步骤: In CDMA2000 LMSD network as an example, to achieve the principles of the embodiments of the method of the present invention shown in Figure 3, the specific process of the flowchart as shown in FIG 4 includes the following steps:

步骤41、如图3所示,本发明首先需要在MS (用户终端)到BSS (基站子系统)、A接口、 ZZ接口中设置START DTMF (开始双音多频)消息、 STOP DTMF (停止双音多频)消息。 Step 41, shown in Figure 3, the present invention first requires MS (user terminal) to the BSS (base station subsystem), A the interface, the interface is provided ZZ START DTMF (Dual Tone Multi Frequency Start) message, STOP DTMF (Dual stop tone multi-frequency) messages. 上述START DTMF消息在用户开始在MS上进行输入后发送,并且携带用户的输入信息。 Above START DTMF message after the user starts input on the MS transmits, and carries the user's input. 上述STOP DTMF消息在用户停止在MS上输入信息后发送。 Above STOP DTMF message sent after the user stops input information on the MS.

在MS和其所属的MSCe之间开始进行一次具体的会话之前,在BSS和其所属的MSCe之间需要进行资源分配。 Before starting a particular conversation between the MS and the MSCe to which it belongs, between the BSS and to which it belongs MSCe required resource allocation. BSS首先向其所属的MSCe发送CM Service Request (连接服务请求)消息,MSCe接收到该CM Service Request消息后,向BSS发送Assignment Request (分配请求)消息。 First sends CM Service Request BSS MSCe belongs thereto (connected to a service request) message, MSCe After receiving the CM Service Request message, transmits Assignment Request (allocation request) message to the BSS. BSS 接收到该Assignment Request消息后,进行相应的带宽等资源分配后,向其所属的MSCe发iilAssignment Complete (分配完成)消息。 After receiving the BSS the Assignment Request message, the corresponding bandwidth resource allocation, to which belongs MSCe hair iilAssignment Complete (Assignment Complete) message.

步骤42、在MS和其所属的MSCe之间开始进行一次具体的会话后,在用户开始在MS上进行按键输入或手写输入等输入信息操作后,MS构造携带用户的输入信息的START DTMF消息,并向BSS发送构造的START DTMF消息,BSS再通过A接口将接收到的START DTMF消息传递给其所属的MSCe。 After step 42, between the MS and the MSCe it belongs to a particular session is started, after the user starts a key input or the handwriting input operation on the input information MS, MS carries configuration information of the user's input START DTMF message, START DTMF message and transmits configuration BSS START DTMF message, BSS then received through the a interface is transmitted to MSCe it belongs.

MSCe之间的zz接口是以SIP协议为基础,于是,上述BSS所属的MSCe 在SIP协议的OPTION消息中携带上述START DTMF消息,并将该option with START DTMF (携带开始双音多频信息的选项)消息传递给与PSTN (公共交换电话网)/PLMN (公共陆地移动网络)相连的目标MSCe。 MSCe zz is the interface between the SIP protocol-based, so, the above-described MSCe BSS belongs above START DTMF message carrying the OPTION message of the SIP protocol, and the option with START DTMF (dual tone multi-start option carrying frequency information ) messaging target MSCe administered PSTN (public switched telephone network) / PLMN (public land mobile network) is connected.

在上述过程中,BSS所属的MSCe还向BSS发送START:DTMF ACK (应答)消息,目标MSCe还向BSS所属的MSCe发送option w, START DTMF ACK (携带开始双音多频信息的选项应答)消息。 In the above process, MSCe BSS belongs also transmits START to the BSS: DTMF ACK (acknowledgment) message, MSCe transmission option w certain MSCe also belongs to the BSS, START DTMF ACK (option response carrying Start DTMF information) message .

步骤43、在用户停止在MS上进行输入信息操作后,MS向BSS发送STOPDTMF消息,表示本次用户的输入信息操作结束。 Step 43, after the user stops the operation on the input information MS, MS STOPDTMF send a message to the BSS, indicating the end of this operation the user input information. BSS再通itA接口将接收到的STOP DTMF消息传递给其所属的MSCe。 BSS interface recanalization itA received MSCe STOP DTMF message to which it belongs.

上述BSS所属的MSCe在SIP协议的OPTION消息中携带上述STOP DTMF消息,并将该option with STOP DTMF (携带停止双音多频信息的选项)消息传递给与PSTN/PLMN相连的目标MSCe。 MSCe above BSS belongs above STOP DTMF message carrying the OPTION message of the SIP protocol, and the option with STOP DTMF (option information carrying stop DTMF) messaging target MSCe given PSTN / PLMN connected.

在上述过程中,BSS所属的MSCe还向BSS发送STOP DTMF ACK (应答)消息,目标MSCe还向BSS所属的MSCe发送option with STOP DTMF ACK (携带停止双音多频信息的选项应答)消息。 In the above process, MSCe BSS belongs also send BSS STOP DTMF ACK (response) message, MSCe send option target MSCe also belongs to the BSS with STOP DTMF ACK (dual-tone multi-frequency stop carrying information option reply) message.

当用户重复进行多次输入信息操作后,重复进行上述START DTMF消息、STOP DTMF消息的传递过程,直到用户的所有按键操作结束,本次会话结束后,执行步骤44。 When the user operation input information is repeated a plurality of times to repeat the START DTMF message, the DTMF message delivery process the STOP, all the key operation until the end user, the end of this session, step 44.

步骤44、 BSS向其所属的MSCe发送clear Request (清除请求)消息, MSCe接收到该dear Request消息后,向BSS发送clear Command (清除命令)消息。 Step 44, BSS transmitted thereto MSCe belongs clear Request (Clear Request) message, after receiving the MSCe dear Request message, to send clear Command BSS (Clear Command) message. BSS接收到该clear Command消息后,释放相应的带宽等资源后,向MSCe发送clear Complete (清除完成)消息。 After receiving the BSS clear Command message, release the corresponding bandwidth resources, sending to the MSCe clear Complete (Clear Complete) message.

以上所述,仅为本发明较佳的具体实施方式,但本发明的保护范围并不局限于此,任何熟悉本技术领域的技术人员在本发明揭露的技术范围内,可轻易想到的变化或替换,都应涵盖在本发明的保护范围之内。 Above, the present invention is merely preferred specific embodiments, but the scope of the present invention is not limited thereto, any skilled in the art in the art within the scope of the invention disclosed can be easily thought of the changes or Alternatively, it shall fall within the protection scope of the present invention. 因此,本发明的保护范围应该以权利要求的保护范围为准。 Accordingly, the scope of the present invention should be defined by the scope of the claims.
