Description

一种移动终端接入IP多媒体系统的方法及装置 技术领域
本发明涉及移动终端技术领域，尤其涉及一种移动终端接入IP多媒体系统的方法及装置。
背景技术
随着社会的持续性发展，人们对手机的依赖也越来越高，同时对手机能够提供的服务质量也就越来越高，例如语音电话，已经由传统的普通语音提高到能够进行视频通话的高清语音，而手机上满足这一需求所采用的技术就是VoLTE(Voice over LTE)，其依赖的整个系统就叫做IMS系统(IP Multimedia Subsystem，IP多媒体系统)，终端在获取IMS服务前，就需要通过LTE网络完成IMS注册，这一终端才能成功接入到IMS系统中去。
在注册的过程中，终端必须要有合法的接入参数才能够正确注册到IMS系统，而这些参数都是从SIM卡里面获取的，也就是说需要SIM卡能够支持IMS，从而终端能够从SIM卡中获取到IMS相关的接入参数，但是在IMS正式商用前发布的SIM卡都还不具备这些IMS接入参数，无法获取IMS服务。已有的技术方案例采用IMSI号(International Mobile Subscriber Identity，国际移动用户识别码)的方式代替IMS参数，每次都由网络侧到归属网络去查询IMS参数，这中方案比较耗时，IMS注册时间耗时较多，用户体验不好。

具体实施方式
应当理解，此处所描述的具体实施例仅仅用以解释本发明，并不用于限定本发明。
在后续的描述中，使用用于表示元件的诸如“模块”、“部件”或“单元”的后缀仅为了有利于本发明的说明，其本身并没有特定的意义。因此，"模块"与"部件"可以混合地使用。

另外，当移动终端100与外部底座连接时，接口单元170可以用作允许通过其将电力从底座提供到移动终端100的路径或者可以用作允许从底座输入的各种命令信号通过其传输到移动终端的路径。从底座输入的各种命令信号或电力可以用作用于识别移动终端是否准确地安装在底座上的信号。输出单元150被构造为以视觉、音频和/或触觉方式提供输出信号(例如，音频信号、视频信号、警报信号、振动信号等等)。
存储器160可以存储由控制器180执行的处理和控制操作的软件程序等等，或者可以暂时地存储己经输出或将要输出的数据(例如，电话簿、消息、静态图像、视频等等)。而且，存储器160可以存储关于当触摸施加到触摸屏时输出的各种方式的振动和音频信号的数据。

这里描述的各种实施方式可以以使用例如计算机软件、硬件或其任何组合的计算机可读介质来实施。对于硬件实施，这里描述的实施方式可以通过使用特定用途集成电路(ASIC)、数字信号处理器(DSP)、数字信号处 理装置(DSPD)、可编程逻辑装置(PLD)、现场可编程门阵列(FPGA)、处理器、控制器、微控制器、微处理器、被设计为执行这里描述的功能的电子单元中的至少一种来实施，在一些情况下，这样的实施方式可以在控制器180中实施。对于软件实施，诸如过程或功能的实施方式可以与允许执行至少一种功能或操作的单独的软件模块来实施。软件代码可以由以任何适当的编程语言编写的软件应用程序(或程序)来实施，软件代码可以存储在存储器160中并且由控制器180执行。
至此，己经按照其功能描述了移动终端。下面，为了简要起见，将描述诸如折叠型、直板型、摆动型、滑动型移动终端等等的各种类型的移动终端中的滑动型移动终端作为示例。因此，本发明能够应用于任何类型的移动终端，并且不限于滑动型移动终端。
参考图2，CDMA无线通信系统可以包括多个移动终端100、多个基站(BS)270、基站控制器(BSC)275和移动交换中心(MSC)280。MSC280被构造为与公共电话交换网络(PSTN)290形成接口。MSC280还被构造为与可以经由回程线路耦接到基站270的BSC275形成接口。回程线路可以根据若干己知的接口中的任一种来构造，所述接口包括例如E1/T1、ATM，IP、PPP、帧中继、HDSL、ADSL或xDSL。将理解的是，如图2中所示的系统可以包括多个BSC2750。
每个BS270可以服务一个或多个分区(或区域)，由多向天线或指向特定方向的天线覆盖的每个分区放射状地远离BS270。或者，每个分区可以由用于分集接收的两个或更多天线覆盖。每个BS270可以被构造为支持多个频率分配，并且每个频率分配具有特定频谱(例如，1.25MHz,5MHz等等)。
分区与频率分配的交叉可以被称为CDMA信道。BS270也可以被称为基站收发器子系统(BTS)或者其它等效术语。在这样的情况下，术语"基站"可以用于笼统地表示单个BSC275和至少一个BS270。基站也可以被称为"蜂窝站"。或者，特定BS270的各分区可以被称为多个蜂窝站。
如图2中所示，广播发射器(BT)295将广播信号发送给在系统内操作 的移动终端100。如图1中所示的广播接收模块111被设置在移动终端100处以接收由BT295发送的广播信号。在图2中，示出了几个全球定位系统(GPS)卫星300。卫星300帮助定位多个移动终端100中的至少一个。
在图2中，描绘了多个卫星300，但是理解的是，可以利用任何数目的卫星获得有用的定位信息。
作为无线通信系统的一个典型操作，BS270接收来自各种移动终端100的反向链路信号。移动终端100通常参与通话、消息收发和其它类型的通信。特定基站270接收的每个反向链路信号被在特定BS270内进行处理。获得的数据被转发给相关的BSC275。BSC提供通话资源分配和包括BS270之间的软切换过程的协调的移动管理功能。BSC275还将接收到的数据路由到MSC280，其提供用于与PSTN290形成接口的额外的路由服务。类似地，PSTN290与MSC280形成接口，MSC与BSC275形成接口，并且BSC275相应地控制BS270以将正向链路信号发送到移动终端100。
基于上述移动终端硬件结构以及通信系统，提出本发明方法各个实施例。
实施例一
如图3所示，本实施例提出一种移动终端接入IP多媒体系统的方法，包括：
S10、移动终端接收网络侧发来的IP多媒体系统IMS接入参数；
S20、将所述IMS接入参数和IMSI号组合为SIP注册包；
S30、通过所述SIP注册包向网络侧发起注册请求；
S40、注册成功后接入IMS系统。
在本实施例中，通过移动终端从网络侧获取IMS接入参数，能够使不具备IMS参数的SIM卡用户能够快速、正确地接入到IMS系统中去，获取IMS服务。
在本实施例中，所述IP多媒体系统(IP Multimedia Subsystem，IMS)是一种网络结构，植根于移动领域，顺应网络IP化的趋势，IMS系统采用SIP协议(Session Initiation Protocol，会话初始协议)进行端到端的呼叫控制，可以支持并应用于语音、视频、数据等多媒体业务，同时也可以应用于Presence(呈现)、InstantMessage(即时消息)等特色业务，可以说，有IP网络的地方就有SIP协议的存在，SIP是类似于HTTP，SIP可以减少应用特别是高级应用的开发时间。
在本实施例中，所述IMS接入参数包括：归属地运营商域名信息HDN、IMS用户公共标示IMPU和IMS用户私有标示IMPI，所述IMSI号(International Mobile Subscriber Identity，国际移动用户识别码)通常存放在SIM卡中。
通常在支持IMS业务的SIM卡中会存在如下的参数：
1)EF_DOMAIN(Home Operators Network Domain)：归属地营运商网络域名，IMS注册的时候需要移动终端携带该参数，网络利用该参数路由寻址IMS的服务器；
2)EF_IMPU(IMS public user identity)：IMS用户公共标示；
3)EF_IMPI(IMS private user identity)：IMS用户私有标示。
移动终端能够从EF_DOMAIN获取到归属地营运商的域名信息(HDN)，从EF_IMPU中获取到IMS用户公共标示(IMPU)，从EF_IMPI中获取到IMS用户私有标示(IMPI)，并由这些参数按照一定的规则组合发送给网络，由网络从中提取用户信息以及归属网域名信息，完成IMS鉴权、注册。
现在很多用户手上的SIM卡还是老式的SIM卡，没有IMS接入参数当这些用户购买了支持VoLTE的终端后还需要更换SIM卡才能够使用，甚至需要更换手机号码，本实施例针对这一类的SIM卡提出了一种方案，使这些用户能够快速地接入到IMS系统中去。
支持VoLTE的移动终端开机上电、完成初始化工作，从SIM卡中获取IMS接入参数，包括IMPU、IMPI以及HDN，并将读取结果缓存到移动终端 的调制解调器中，如果获取失败，即确认这张SIM卡没有IMS的接入参数，则接下来继续判断是否首次开机，如果不是首次开机，则通过SIM卡的IMSI号从IMS存储区匹配IMS接入参数，如果匹配成功，按RFC3261将所述IMS接入参数和IMSI号组装SIP注册包，向网络侧发起注册。如果匹配失败，说明移动终端已经没能从本地(SIM卡或者IMS接入参数存储区)获取到IMS接入参数，则需要移动终端通过但不限于IP链路、短信或者SIP数据包向网络侧发送IMS接入参数分配请求，携带的参数主要包括SIM卡的IMSI号；网络侧在收到移动终端请求后向SIM卡归属地网络查询该SIM卡的IMPU、IMPI以及HDN；然后网络侧按照相同的通信方式向移动终端下发查询到的IMPU、IMPI以及HDN；移动终端收到响应后，解码出IMPU、IMPI以及HDN，然后和IMSI绑定起来存储到移动终端中；移动终端重新用网络分配的IMPU、IMPI以及HDN信息组合出SIP注册包，向网络发起注册请求；注册成功后接入IMS系统。
在本实施例中，所述RFC3261为一种SIP协议。
在本实施例中，所述IMS接入参数分配请求中包括对应SIM卡的IMSI号和请求类型标示，包含的主要字段如下：
<IMSI>_req@ims.mcc<MCC>.mnc<MNC>.3gppnetwork.org
例如IMSI号为460010999999999，请求携带的字段为：
460010999999999_req@ims.mcc460.mnc010.3gppnetwork.org
网络侧收到移动终端的请求后，检测到终端发送的信令带有req标示，也即请求类型标示，该标示说明需要网络侧查询对应的IMS接入参数，这时网络侧可以从请求中截取出IMSI号，然后到归属网络去查询SIM卡的IMS接入参数，查询成功后通过同样的方式反馈给终端。格式如下：
IMPI_IMPU@ims.HDN。
实施例二
如图4所示，在本实施例中，基于实施例一，所述步骤S10之前还包括：
S01、开启移动终端，读取SIM卡参数，并将所述SIM卡参数保存至移动终端的调制解调器中；
S02、判断所述SIM卡参数中是否包含IMS接入参数，若是，则进入步骤S20、将所述IMS接入参数和IMSI号组合为SIP注册包；
否则，进入步骤S03、判断所述移动终端是否首次开机，若不是，则进入步骤S031、通过SIM卡的IMSI号从IMS存储区匹配出IMS接入参数；
S032、判断所述IMSI号和IMS接入参数是否匹配成功，若是，则进入步骤S20、将所述IMS接入参数和IMSI号组合为SIP注册包；
若移动终端是首次开机或所述IMSI号和IMS接入参数匹配失败，则进入步骤S04、向网络侧发送IMS接入参数分配请求；
S05、网络侧从所述IMS接入参数分配请求中获取IMSI号，然后到归属网络查询SIM卡的IMS接入参数，并将所述IMS接入参数发送至移动终端。
之后则进入步骤S10，如实施例一所述。
现有技术方案中，移动终端直接读取IMSI号，来组合IMPU、IMPI以及HDN，在移动终端把这些参数递交给网络后，网络侧需要多次查询才能正确找到归属地网络的IMS服务器，导致注册的时间较长，影响用户体验，且每次开机、或者从无信号区域回来，这些流程都要重新执行；而在本实施例中，只需要首次开机时，检测到从SIM卡读取IMS接入参数失败，即通过移动终端从网络侧获取IMS接入参数，并把所述IMS接入参数保存在移动终端的IMS存储区，当二次开机时，直接从IMS存储区匹配出IMS接入参数，和IMSI号组合为SIP注册包；通过所述SIP注册包向网络侧发起注册请求；注册成功后接入IMS系统，与现有技术相比，能更快速接入到IMS系统中去。
实施例三

在本实施例中，所述IMS接入参数包括：归属地运营商域名信息HDN、IMS用户公共标示IMPU和IMS用户私有标示IMPI。
在本实施例中，通过移动终端从网络侧获取IMS接入参数，能够使不具备IMS参数的SIM卡用户能够快速、正确地接入到IMS系统中去，获取IMS服务。
实施例四
如图6所示，在本实施例中，基于实施例三，移动终端接入IP多媒体系统的装置还包括：
读取模块50，设置为开启移动终端，读取SIM卡参数，并将所述SIM卡参数保存至移动终端的调制解调器中；
第一判断模块60，设置为判断所述SIM卡参数中是否包含IMS接入参数，若是，则将所述IMS接入参数和IMSI号组合为SIP注册包；
第二判断模块70，设置为当所述SIM卡参数中未包含IMS接入参数时，判断所述移动终端是否首次开机，若不是，则通过SIM卡的IMSI号从IMS存储区匹配出IMS接入参数；
第三判断模块80，设置为判断所述IMSI号和IMS接入参数是否匹配 成功，若是，则将所述IMS接入参数和IMSI号组合为SIP注册包；
发送模块90，设置为当移动终端是首次开机或所述IMSI号和IMS接入参数匹配失败时，向网络侧发送IMS接入参数分配请求；
查询模块100，设置为网络侧从所述IMS接入参数分配请求中获取IMSI号，然后到归属网络查询SIM卡的IMS接入参数，并将所述IMS接入参数发送至移动终端。
在本实施例中，只需要首次开机时，检测到从SIM卡读取IMS接入参数失败，即通过移动终端从网络侧获取IMS接入参数，并把所述IMS接入参数保存在移动终端的IMS存储区，当二次开机时，直接从IMS存储区匹配出IMS接入参数，和IMSI号组合为SIP注册包；通过所述SIP注册包向网络侧发起注册请求；注册成功后接入IMS系统，与现有技术相比，能更快速接入到IMS系统中去。
在本实施例中，所述发送模块的通信方法具体为：
移动终端通过但不限于IP链路、短信或者SIP数据包向网络侧发送IMS接入参数分配请求。
在本实施例中，所述IMS接入参数分配请求中包括对应SIM卡的IMSI号和请求类型标示，例如，所述请求类型标示为req字符，IMSI号为460010999999999，请求携带的字段为：
460010999999999_req@ims.mcc460.mnc010.3gppnetwork.org
网络侧收到移动终端的请求后，检测到终端发送的信令带有req请求类型标示，该标示说明需要网络侧查询对应的IMS接入参数，这时网络侧可以从请求中截取出IMSI号，然后到归属网络去查询SIM卡的IMS接入参数，查询成功后通过同样的方式反馈给终端。
如图7所示为移动终端接入IP多媒体系统的系统结构图，包括移动终端和网络侧，其中，移动终端包括SIM卡、IMS接入参数存储区和调制解调器，SIM卡为用户提供身份信息及IMS接入参数，IMS接入参数存储区用于存储IMS接入参数，调制解调器用于通过空中接口接入网络侧，网 络侧负责处理移动终端的请求，如：IMS接入参数分配请求、注册请求和接入请求。

    第三判断模块，设置为判断所述IMSI号和IMS接入参数是否匹配成功，若是，则将所述IMS接入参数和IMSI号组合为SIP注册包；
    发送模块，设置为当移动终端是首次开机或所述IMSI号和IMS接入参数匹配失败时，向网络侧发送IMS接入参数分配请求；
    查询模块，设置为网络侧从所述IMS接入参数分配请求中获取IMSI号，然后到归属网络查询SIM卡的IMS接入参数，并将所述IMS接入参数发送至移动终端。
  9. 根据权利要求8所述的一种移动终端接入IP多媒体系统的装置，其中，所述发送模块的通信方法为：
    移动终端通过但不限于IP链路、短信或者SIP数据包向网络侧发送IMS接入参数分配请求。
  10. 根据权利要求8所述的一种移动终端接入IP多媒体系统的装置，其中，所述IMS接入参数分配请求中包括对应SIM卡的IMSI号和请求类型标示。
