在某些紧急情况发生时，各种通信设备、通信线路或供电线路可能被损坏，从而导致发生紧急情况的地区通信中断。在面临紧急情况时，采用的通信手段被称为应急通信。
应急通信是一种暂时性的特殊通信手段，一般而言，应急通信的方法包括：徒步施放光缆、部署应急通信车、空投基站、部署卫星等。其中，徒步施放光缆受环境影响较大、实施困难、部署较慢；应急通信车的覆盖范围较小，仅支持少量用户的通信业务需求，并且在发生地震、洪水等灾害时，应急通信车也很难开到受灾地区；空投基站的成本过高，并且空投的成功率无法保证，可靠性不高；卫星通信受卫星资源的限制，支持的用户量也较少。
因此，在发生紧急情况时，如何提供一种可靠的应急通信手段，是目前亟待解决的问题。

附图说明
为了更清楚地说明本发明实施例或现有技术中的技术方案，下面将对实施例或现有技术描述中所需要使用的附图作一简单地介绍，显而易见地，下面描述中的附图是本发明的一些实施例，对于本领域普通技术人员来讲，在不付出创造性劳动性的前提下，还可以根据这些附图获得其他的附图。
图1为本发明实施例提供的应急通信系统架构示意图；
图2为本发明实施例提供的基站实施例一的结构示意图；
图3为本发明实施例提供的用户设备实施例一的结构示意图；
图4为本发明实施例提供的应急通信方法实施例一的流程图；
图5为本发明实施例提供的应急通信方法实施例二的流程图。
具体实施方式
为使本发明实施例的目的、技术方案和优点更加清楚，下面将结合本发明实施例中的附图，对本发明实施例中的技术方案进行清楚、完整地描述，显然，所描述的实施例是本发明一部分实施例，而不是全部的实施例。基于本发明中的实施例，本领域普通技术人员在没有做出创造性劳动前提下所获得的所有其他实施例，都属于本发明保护的范围。
在发生突发事件或自然灾害的地区，通信很可能中断，若通信终端，则需要采用应急通信的方法为通信中断的地区提供通信服务。但目前的应急通信方法都存在一定的问题，对应急通信需求的支持有限。
考虑到随着长期演进(Long Term Evolution，简称LTE)系统的演进，LTE系统的系统容量、传输速率、覆盖范围等参数都得到的大幅的提升，因此可以将LTE系统应用到应急通信领域，采用无线通信的方式进行应急通信服务。
再考虑到应急通信的实际需求，部署应急通信车或空投基站的方法都存在一定的问题，因此本发明实施例提出一种应急通信方法和装置，通过在能够从空中无障碍地在需要应急通信的区域移动的交通工具，例如飞机上设置浮空基站，使用浮空基站为需要应急通信服务的区域中的UE提供应急通信服务。
图1为本发明实施例提供的应急通信系统架构示意图，如图1所示，区域11和区域12分别为两块通信中断的区域，需要对区域11和区域12中的用户设备(User Equipment，简称UE)15提供应急通信服务。区域13为进行正常通信的区域，基站14为区域13中的UE15提供服务，基站14可以连接至提供通信服务的核心网设备。区域11位于区域12和区域13之间，区域11与区域12和区域13分别相邻，区域12和区域13不相邻。在空中的飞行器16上携带有浮空基站17，在空中的飞行器18上携带有浮空基站19。飞行器16和飞行器18可以是固定翼飞机、直升飞机、无人机或热气球等任一种能够飞行的装置。
若仅对区域11中的UE15提供应急通信，可以令飞行器16或飞行器18在区域11上空或区域11附近的空域飞行，或者令飞行器16或飞行器18从区域11上空飞过。当飞行器16或飞行器18飞经区域11上空时，区域11中的UE15即可位于浮空基站17或浮空基站19的覆盖范围内，此时UE15即可接入浮空基站17或浮空基站19，并与浮空基站17或浮空基站19之间进行数据传输。浮空基站17或浮空基站19能够与基站14交互数据，通过基站14为区域11中的UE15提供数据传输服务；或者浮空基站17或浮空基站19将接收到的区域11中UE15发送的数据缓存下来，当携带浮空基站17或浮空基站19的飞行器16或飞行器18飞行到基站14的覆盖范围内时，浮空基站17或浮空基站19再将缓存的数据发送至基站14，并接收基站14需要发给区域11中UE15的数据并进行缓存，当飞行器16或飞行器18再次飞行到区域11上空时，浮空基站17或浮空基站19再将缓存的数据发送给区域11中的UE15。这样，即可实现对区域11中的UE15提供应急通信的目的。
若需要同时对区域11和区域12中的UE15提供应急通信，可以令飞行器16在区域11上空或区域11附近的空域飞行，令飞行器18在区域12上空或区域11附近的空域飞行。当飞行器16飞经区域11上空时，区域11中的UE15即可位于浮空基站17的覆盖范围内，此时UE15即可接入浮空基站17，并与浮空基站17之间进行数据传输；当飞行器18飞经区域12上空时，区域12中的UE15即可位于浮空基站19的覆盖范围内，此时UE15即可接入浮空基站19，并与浮空基站19之间进行数据传输。浮空基站17能够与基站14交互数据，通过基站14为区域11中的UE15提供数据传输服务；浮空基 站19能够与浮空基站17交互数据，通过浮空基站17以及基站14为区域12中的UE15提供数据传输服务。或者浮空基站17将接收到的区域11中UE15发送的数据缓存下来，当携带浮空基站17的飞行器16飞行到基站14的覆盖范围内时，浮空基站17再将缓存的数据发送至基站14，并接收基站14需要发给区域11中UE15的数据并进行缓存，当飞行器16再次飞行到区域11上空时，浮空基站17再将缓存的数据发送给区域11中的UE15；浮空基站19将接收到的区域12中UE15发送的数据缓存下来，当携带浮空基站19的飞行器18飞行到浮空基站17的覆盖范围内时，浮空基站19再将缓存的数据发送至浮空基站17，并接收浮空基站17从基站14接收并缓存的需要发给区域12中UE15的数据并进行缓存，当飞行器18再次飞行到区域12上空时，浮空基站19再将缓存的数据发送给区域12中的UE15，在这种情况下，浮空基站17相当于作为浮空基站19的中继基站。这样，即可实现对区域11和区域12中的UE15同时提供应急通信的目的。
浮空基站17和浮空基站19可以实现与普通基站14相同的功能，并且鉴于浮空基站17和浮空基站19位于飞行器16和飞行器18上，而飞行器16和飞行器18可能处于高速运动的状态中，浮空基站17和浮空基站19所提供的接入能力仍然有限，因此浮空基站17和浮空基站19还需要具有快速资源分配、快速数据传输以及快速资源回收等功能。本发明下述各实施例提供的应急通信方法、基站和用户设备都是基于图1所示的应急通信系统架构实现的。
图2为本发明实施例提供的基站实施例一的结构示意图，如图2所示，本实施例的基站包括：
接收模块21，用于接收用户设备发送的上行业务请求消息，所述上行业务请求消息中包括业务类型信息。
具体地，基于图1所示的应急通信系统架构，若需要对区域11中的UE15提供应急通信服务，则区域11中的UE15需要向浮空基站17申请上行资源，当浮空基站17为区域11中的UE15分配上行资源后，区域11中的UE15即可向浮空基站17发送上行数据，浮空基站17可以将区域11中的UE15发送的上行数据转发至基站14，或者浮空基站17先将区域11中的UE15发送的上行数据缓存下来，当浮空基站17移动至基站14的覆盖范围内 时，浮空基站17再将缓存的数据发送至基站14。由于浮空基站17可能处于高速运动状态，区域11中的某一UE15可能只有很短的时间能够位于浮空基站17的覆盖范围内，因此需要区域11中的UE15和浮空基站17具有快速资源分配、快速数据传输的能力；另外浮空基站17所提供的接入能力仍有限，因此区域11中的UE15和浮空基站17还需要具有快速资源回收的能力，以便区域11中的其它UE15接入浮空基站17并传输数据。同理，若需要对区域12中的UE15提供应急通信服务，浮空基站19也需要具有上述能力。
根据上述需求，本实施例提供的基站包括接收模块21，用于接收用户设备发送的上行业务请求消息，其中该上行业务请求消息中包括业务类型信息。业务类型信息是用于表征用户设备需要传输的业务数据的特征的信息，当接收模块21接收到上行业务请求信息后，即可获知发送上行业务请求消息的用户设备需要传输什么业务数据，从而可以根据用户设备需要传输的业务类型的不同，为用户设备分配相应的上行资源。其中，业务类型信息包括业务类型和/或业务数据大小。业务类型包括文本类、语音类、视频类中的任意一项。
处理模块22，用于根据接收模块21接收的所述业务类型信息为所述用户设备分配上行资源。
具体地，当接收模块21接收到用户设备发送的上行业务请求消息后，处理模块22即可根据上行业务请求消息中的业务类型信息为用户设备分配相应的上行资源。
处理模块22，具体用于根据接收模块21接收的业务类型确定是否为所述用户设备分配上行资源，和/或根据业务数据大小为用户设备分配与业务数据大小对应的上行资源。当业务类型信息为业务类型时，处理模块22可以首先根据不同的业务类型确定是否为用户设备分配上行资源。由于用户设备传输视频类数据所需的上行资源大于传输语音类数据所需的上行资源，传输语音类数据所需的上行资源大于传输文本类数据所需的上行资源，而在进行应急通信时，通信资源一般较为有限，因此可能仅允许接入的用户设备发送文本类的上行数据，或仅允许接入的用户设备发送文本类或语音类的上行数据等，避免一个用户占用过多的通信资源而导致其他用户设备无法进行应急通信。当业务类型信息为业务数据大小时，处理模块22即可根据业务数 据大小为用户设备分配相应的上行资源。或者基站中还可以预设有不同业务类型所对应的上行资源大小，当业务类型信息为业务类型时，处理模块22即可根据业务类型为用户设备分配相应的上行资源。
例如，根据不同的数据类型的特征，可以为文本类数据预设10kB(k Byte，千字节)的上行资源，为语音类数据预设100kB的上行资源，为视频类数据预设10MB(M Byte，兆字节)的上行资源。当处理模块22检测到相应的数据类型后，即确定为该用户设备分配相应的上行资源。
总之，处理模块22可以根据业务类型信息为用户设备分配上行资源，即在接收模块21接收到用户设备发送的上行业务请求消息后，处理模块22即可确定为用户设备所分配的上行资源。
发送模块23，用于向所述用户设备发送上行业务请求应答消息，所述上行业务请求应答消息携带处理模块22分配的上行资源的指示信息。
具体地，当处理模块22确定为用户设备分配的上行资源后，发送模块23向用户设备发送上行业务请求应答消息，该上行业务请求应答消息用于为用户设备分配处理模块22确定的上行资源。
接收模块21，还用于接收所述用户设备发送的上行业务数据，所述上行业务数据是所述用户设备在发送模块23发送的指示信息所指示的上行资源上发送的。
具体地，当用户设备接收到发送模块23发送的上行业务请求应答消息后，即可在为其分配的上行资源上向基站发送上行业务数据。因此，接收模块21，还用于接收用户设备在为其分配的上行资源上发送的上行业务数据。
发送模块23，还用于在接收模块21接收到所述上行业务数据后，向所述用户设备发送应答确认消息。
具体地，当接收模块21接收到用户设备发送的上行业务数据后，发送块23还用于向用户设备发送应答确认消息，以使用户设备确认上行业务数据发送成功。
进一步地，参照图1所示的应急通信系统架构，当浮空基站17的接收模块21接收到区域11中的UE15发送的上行业务数据后，若浮空基站17位于基站14的覆盖范围内，则发送模块23即可将区域11中的UE15发送的上行业务数据通过基站14转发出去。若浮空基站17并未位于基站14的覆盖范围 内，则浮空基站17中还可以包括存储模块，存储模块可以先将接收模块21接收到区域11中的UE15发送的上行业务数据缓存下来，当浮空基站17移动至基站14的覆盖范围时，发送模块23再将存储模块缓存的数据通过基站14转发出去。
处理模块22，还用于在接收模块21接收到所述上行业务数据后，释放所述上行资源。
具体地，当接收模块21接收到用户设备发送的上行业务数据后，处理模块22还释放为用户设备分配的上行资源，从而可以将释放的上行资源分配给其他用户设备使用，提高资源使用效率。
本实施例提供的基站，通过接收用户设备发送的包括业务类型信息的上行业务请求消息，并根据业务类型信息为用户设备分配上行资源，使用户设备可以在发送上行业务请求消息后就接收到基站分配的上行资源，并在该上行资源上发送上行业务数据，从而可以使用户设备进行快速的接入和上行业务数据传输，适用于应急通信中。
进一步地，图2所示实施例的基站中，发送模块23，还用于在接收模块21接收所述用户设备发送的上行业务数据之前，广播加密的公钥信息和安全算法索引信息，所述加密的公钥信息包括所述用户设备加密所使用的公钥，所述安全算法索引信息包括所述用户设备加密所使用的算法；接收模块21，具体用于接收所述用户设备发送的上行业务数据，所述上行业务数据使用所述算法和所述公钥进行加密；处理模块22，还用于在接收模块21接收所述用户设备发送的上行业务数据之后，使用所述算法和私钥对所述上行业务数据进行解密，所述公钥和所述私钥不同。
具体地，考虑到应急通信数据的安全性，对于用户设备传输的上行业务数据，可以进行加密处理。但传统的数据加密传输方案中，需要由基站和用户设备进行密钥的协商，使用户设备使用与基站协商好的密钥对上行业务数据加密后再传输，但传统的数据加密传输方案需要基站和用户设备之间进行密钥协商的过程，这需要一定的时间以及一定的通信资源，并不适用于应急通信中。
因此，本发明实施例提供的基站中，提供了一种新的数据加密传输方案。首先，发送模块23，在接收模块21接收所述用户设备在所述上行资源 上发送的上行业务数据之前，广播加密的公钥信息和安全算法索引信息，所述加密的公钥信息包括所述用户设备加密所使用的公钥，所述安全算法索引信息包括所述用户设备加密所使用的算法。也就是说，基站无需和用户设备进行密钥协商，而是由发送模块23广播加密的公钥信息和安全算法索引信息。其中，安全算法索引信息用于指示用户设备发送上行业务数据所使用的加密算法，而加密的公钥信息中包括用户设备对上行业务数据进行加密使用的公钥。基站覆盖范围内的用户设备都可以接收到发送模块23广播的公钥信息和安全算法索引信息。发送模块23广播的公钥信息和安全算法索引信息需要在接收模块21接收用户设备发送的上行业务数据之前发送，优选地，发送模块23在接收模块21接收用户设备发送的上行业务请求消息之前广播公钥信息和安全算法索引信息。
然后接收模块21，接收用户设备在所述上行资源上发送的上行业务数据，该上行业务数据是用户设备使用发送模块23广播的公钥和安全算法进行加密的。当接收模块21接收到该上行的业务数据后，使用与用户设备相同的算法和与广播的公钥不同的私钥对该上行业务数据进行解密，从而得到用户设备需要发送的上行业务数据。
用户设备使用安全算法索引信息指示的加密算法和加密的公钥信息中的公钥加密的上行业务数据无法使用公钥解密，必须使用私钥才能解密，而该私钥仅保存于基站中。因此虽然发送模块23广播了加密的公钥信息和安全算法索引信息，但用户设备使用安全算法索引信息指示的加密算法和加密的公钥信息中的公钥加密的上行业务数据仍然是安全的。这样无需基站和每一用户设备进行密钥的协商，而是基站可以采用广播的方式向所有用户设备广播加密的公钥信息，从而节约了基站和用户设备之间进行密钥写上的时间以及通信资源，使图2所示实施例的基站更加适用于应急通信。
进一步地，图2所示实施例的基站中，接收模块21，还用于接收所述用户设备发送的结束标识，所述结束标识是所述用户设备在发送模块23发送的指示信息所指示的上行资源上发送的；处理模块22，具体用于若检测到所述结束标识，释放所述上行资源。
具体地，一般地移动通信系统中，当基站需要释放分配给用户设备的上行资源时，首先需要向用户设备发送询问消息，当用户设备确认已经发送完 全部的数据时，才能释放分配给用户设备的上行资源；或者基站需要在接收到用户设备上报的已经发送完数据的指示消息时才能释放分配给用户设备的上行资源。但这仍然需要在基站和用户设备之间产生额外的信令或消息交互，从而致使释放上行资源的过程不及时，进而可能对其他需要请求上行资源的用户设备产生影响。
因此，在图2所示实施例的基站中，接收模块21在接收用户设备在所述上行资源上发送的上行业务数据的同时，还接收用户设备发送的结束标识。也就是说，用户设备在为其分配的上行资源上发送上行业务数据的同时，还向基站发送结束标识。该结束标识用于向基站指示已经发送完上行业务数据，可以将为用户设备分配的上行资源释放。处理模块22在检测到该结束标识时，即可将为用户设备分配的上行资源释放掉。从而基站和用户设备无需进行额外的交互后才释放上行资源，进一步地节约了应急通信所需的时间和对上行资源的占用，使图2所示实施例的基站更加适用于应急通信。
进一步地，图2所示实施例的基站中，发送模块23，还用于在接收模块21接收用户设备发送的上行业务请求消息之前，广播无线资源控制(Radio Resource Control，RRC)配置信息，以使接收到所述RRC配置信息的用户设备获取RRC配置信息。
具体地，由于用户设备在接入基站之前，还需要获取RRC配置信息，才能够获取基站的相关配置信息，从而进行后续接入流程。而用户设备和基站之间进行RRC配置信息的交互仍需要占用一定的时间并且消耗一定的通信资源。因此，图2所示实施例的基站中，发送模块23，还用于广播RRC配置信息，发送模块23广播的RRC配置信息需要在接收模块21接收用户设备发送的上行业务请求消息之前发送。也就是说，本实施例的基站将RRC配置信息从基站向每个用户设备单独发送的方式改为了基站向所有用户设备同时广播。这样节约了基站和用户设备之间进行RRC配置信息的交互所需的时间以及通信资源，使图2所示实施例的基站更加适用于应急通信。
进一步地，图2所示实施例的基站中，发送模块23，还用于在接收模块21接收用户设备发送的上行业务请求消息之前，广播应急通信指示信息，所述应急通信指示信息用于使接收到所述应急通信指示信息的用户设备获知所述基站处于应急通信模式并在向所述基站发送的所述上行业务请求消息中携 带所述业务类型信息。
具体地，由于图2所示实施例的基站是用于应急通信，而在正常的非应急通信中，用户设备不会在向基站发送上行业务请求消息时携带业务类型信息。因此，图2所示实施例的基站中，发送模块23还在接收模块21接收用户设备发送的上行业务请求消息之前，广播应急通信指示信息，使接收到该应急通信指示信息的用户设备获知基站正处于应急通信模式。当用户设备获知基站正处于应急通信模式时，即在向基站发送的上行业务请求消息中携带业务类型信息。
进一步地，图2所示实施例的基站中，发送模块23，还用于在接收模块21接收用户设备发送的上行业务请求消息之前，广播支持的业务类型信息。
具体地，在图2所示实施例的基站在提供应急通信服务时，为了尽可能地保证更多的用户设备传输上行业务数据，因此，基站需要根据自身的能力或需要提供应急通信服务的区域的用户数量确定能够支持的业务类型信息。例如；若基站提供的接入能力较强或者需要提供应急通信的区域中用户数量较少，则基站可以支持文本类、语音类以及视频类业务，若基站提供的接入能力较弱或者需要提供应急通信的区域中用户数量较多，则基站可以仅支持文本类业务或者仅支持文本类和语音类业务。为了使需要进行应急通信区域的用户设备获知基站所支持的业务类型信息，发送模块23在接收模块21接收用户设备发送的上行业务请求消息之前，广播支持的业务类型信息，从而可以使用户设备在向基站发送上行业务请求消息时，仅携带基站支持的业务类型信息。
进一步地，图2所示实施例的基站中，接收模块21，还用于在接收用户设备发送的上行业务请求消息之前，接收用户设备发送的随机接入请求消息；发送模块23，还用于在接收模块21接收到所述用户设备所述随机接入请求消息后，向所述用户设备发送随机接入响应消息。
具体地，用户设备接入未知的基站之前，还需要向基站发送随机接入请求消息，当用户设备接收到基站反馈的随机接入响应消息后，才能继续进行接入流程。因此，图2所示的基站中，接收模块21在接收用户设备发送的上行业务请求消息之前，还接收用户设备发送的随机接入响应消息。若基站允许该用户设备接入，则发送模块23再向用户设备发送随机接入响应消息。
图3为本发明实施例提供的用户设备实施例一的结构示意图，如图3所示，本实施例的用户设备包括：
发送模块31，用于向基站发送上行业务请求信息，所述上行业务请求信息中包括业务类型信息。
具体地，本实施例提供的用户设备基于图1所示的应急通信系统架构，可以为区域11中的UE15或区域12中的UE15。
本实施例提供的用户设备包括发送模块31，用于向基站发送上行业务请求信息，所述上行业务请求信息中包括业务类型信息。业务类型信息是用于表征用户设备需要传输的业务数据的特征的信息，当基站接收到上行业务请求信息后，即可获知用户设备需要传输什么业务数据，从而可以根据用户设备需要传输的业务类型的不同，为用户设备分配相应的上行资源。其中，业务类型信息包括业务类型和/或业务数据大小。业务类型包括文本类、语音类、视频类中的任意一项。
接收模块32，用于在发送模块31向所述基站发送所述上行业务请求消息后，接收所述基站发送的上行业务请求应答消息，所述上行业务请求应答消息携带为所述用户设备分配的上行资源的指示信息，所述上行资源是所述基站根据所述业务类型信息为所述用户设备分配的。
具体地，当基站接收到发送模块31发送的上行业务请求消息后，即可根据上行业务请求消息中的业务类型信息为用户设备分配相应的上行资源。基站具体用于根据业务类型确定是否为所述用户设备分配上行资源，和/或根据业务数据大小为用户设备分配与业务数据大小对应的上行资源。当业务类型信息为业务类型时，基站可以首先根据不同的业务类型确定是否为用户设备分配上行资源。由于用户设备传输视频类数据所需的上行资源大于传输语音类数据所需的上行资源，传输语音类数据所需的上行资源大于传输文本类数据所需的上行资源，而在进行应急通信时，通信资源一般较为有限，因此可能仅允许接入的用户设备发送文本类的上行数据，或仅允许接入的用户设备发送文本类或语音类的上行数据等，避免一个用户占用过多的通信资源而导致其他用户设备无法进行应急通信。当业务类型信息为业务数据大小时，基站即可根据业务数据大小为用户设备分配相应的上行资源。或者基站中还可以预设有不同业务类型所对应的上行资源大小，当业务类型信息为业 务类型时，基站即可根据业务类型为用户设备分配相应的上行资源。例如，根据不同的数据类型的特征，基站可以为文本类数据预设10kB(k Byte，千字节)的上行资源，为语音类数据预设100kB的上行资源，为视频类数据预设10MB(M Byte，兆字节)的上行资源。当基站检测到相应的数据类型后，即确定为该用户设备分配相应的上行资源。总之，基站可以根据业务类型信息为用户设备分配上行资源。
当基站确定为用户设备分配的上行资源后，接收模块32即可接收到基站发送的上行业务请求应答消息，该上行业务请求应答消息用于为用户设备分配基站确定的上行资源。
处理模块33，用于在接收模块32接收到所述上行业务请求应答消息后，确定在所述上行资源上向所述基站发送上行业务数据。
具体地，当接收模块32接收到基站发送的上行业务请求应答消息后，处理模块33即可从上行业务请求应答消息中获取基站为用户设备分配的上行资源，并确定在该上行资源上向基站发送上行业务数据。
发送模块31，还用于处理模块33确定在所述上行资源上向所述基站发送上行业务数据后，在所述上行资源上向所述基站发送上行业务数据。
具体地，发送模块31还用于在处理模块33确定的上行资源上向基站发送上行业务数据。
接收模块32，还用于在发送模块31在所述上行资源上向所述基站发送上行业务数据后，接收所述基站发送的应答确认消息，所述应答确认消息为所述基站接收到所述上行业务数据并且确定释放所述上行资源后发送的。
具体地，当基站接收到发送模块31发送的上行业务数据后，还会向用户设备发送应答确认消息，接收模块32还用于接收基站发送的应答确认消息，从而可以使用户设备确认上行业务数据发送成功。
本实施例提供的用户设备，通过在向基站发送包括业务类型信息的上行业务请求信息，并接收基站根据业务类型信息为用户设备分配的上行资源，使用户设备可以在发送上行业务请求消息后就接收到基站分配的上行资源，并在该上行资源上发送上行业务数据，从而可以使用户设备进行快速的接入和上行业务数据传输，适用于应急通信中。
进一步地，图3所示实施例的用户设备中，接收模块32，还用于在发送 模块31向基站发送上行业务请求信息之前，接收所述基站广播的公钥信息和安全算法索引信息，所述加密的公钥信息包括所述用户设备加密所使用的公钥，所述安全算法索引信息包括所述用户设备加密所使用的算法；发送模块31，具体用于处理模块33确定在所述上行资源上向所述基站发送上行业务数据后，在所述上行资源上向所述基站发送上行业务数据，所述上行业务数据使用所述算法和所述公钥进行加密，以使所述基站使用所述算法和私钥对所述上行数据进行解密，所述公钥和所述私钥不同。
具体地，考虑到应急通信数据的安全性，对于用户设备传输的上行业务数据，可以进行加密处理。但传统的数据加密传输方案中，需要由基站和用户设备进行密钥的协商，使用户设备使用与基站协商好的密钥对上行业务数据加密后再传输，但传统的数据加密传输方案需要基站和用户设备之间进行密钥协商的过程，这需要一定的时间以及一定的通信资源，并不适用于应急通信中。
因此，本发明实施例提供的用户设备，提供了一种新的数据加密传输方案。首先，接收模块32，在发送模块31向基站发送上行业务请求信息之前，接收基站广播的加密的公钥信息和安全算法索引信息，所述加密的公钥信息包括所述用户设备加密所使用的公钥，所述安全算法索引信息包括所述用户设备加密所使用的算法。也就是说，基站无需和用户设备进行密钥协商，而是由接收模块32接收基站广播的加密的公钥信息和安全算法索引信息。其中，安全算法索引信息用于指示用户设备发送上行业务数据所使用的加密算法，而加密的公钥信息中包括用户设备对上行业务数据进行加密使用的公钥。接收模块32需要在发送模块31向基站发送上行业务数据之前接收基站广播的公钥信息和安全算法索引信息，优选地，接收模块32在发送模块31向基站发送上行业务请求消息之前接收基站广播的公钥信息和安全算法索引信息。
然后发送模块31，在所述上行资源上向所述基站发送上行业务数据，其中该上行业务数据由处理模块33使用所述算法和所述公钥进行加密，以使所述基站使用所述算法和私钥对所述上行数据进行解密，所述公钥和所述私钥不同。处理模块33使用安全算法索引信息指示的加密算法和加密的公钥信息中的公钥加密的上行业务数据无法使用公钥解密，必须使用私钥才能解 密，而该私钥仅保存于基站中。因此虽然发送模块31向基站发送的上行业务数据可能被其他设备接收到，加密上行业务数据所使用的算法和公钥也是基站广播的，但由于解密该上行业务数据的私钥进存储于基站中，所以发送模块31发送的上行业务数据是安全的。这样无需基站和每一用户设备进行密钥的协商，而是基站可以采用广播的方式向所有用户设备广播加密的公钥信息，从而节约了基站和用户设备之间进行密钥写上的时间以及通信资源，使图3所示实施例的用户设备更加适用于应急通信。
进一步地，图3所示实施例的用户设备中，发送模块31，具体用于处理模块33确定在所述上行资源上向所述基站发送上行业务数据后，在所述上行资源上向所述基站发送结束标识，所述结束标识用于使所述基站在检测到所述结束标识后确定释放所述上行资源。
具体地，一般地移动通信系统中，当用户设备向基站发送数据后，基站需要向用户设备发送询问消息，询问用户设备是否已经发送完全部的数据，当基站接收到用户设备发送的已经发送完全部的数据的指示消息后，基站才能释放分配给用户设备的上行资源。但这仍然需要在基站和用户设备之间产生额外的信令或消息交互，从而致使释放上行资源的过程不及时，进而可能对其他需要请求上行资源的用户设备产生影响。
因此，在图3所示实施例的用户设备中，发送模块31，在基站分配的上行资源上向基站发送上行业务数据的同时，还在该上行资源上向基站发送结束标识。该结束标识用于向基站指示用户设备已经发送完上行业务数据，当基站检测到该结束标识后即可确定释放所述上行资源。从而基站和用户设备无需进行额外的交互后才释放上行资源，进一步地节约了应急通信所需的时间和对上行资源的占用，使图3所示实施例的用户设备更加适用于应急通信。
进一步地，图3所示实施例的用户设备中，接收模块32，还用于在发送模块31向基站发送上行业务请求信息之前，接收所述基站广播的RRC配置信息；处理模块33，还用于根据所述RRC配置信息进行RRC配置。
具体地，由于用户设备在接入基站之前，还需要获取RRC配置信息，才能够获取基站的相关配置信息，从而进行后续接入流程。而用户设备和基站之间进行RRC配置信息的交互仍需要占用一定的时间并且消耗一定的通 信资源。因此，图3所示实施例的用户设备中，接收模块32，还用于接收基站广播的RRC配置信息，接收模块32需要在发送模块31向基站发送上行业务请求信息之前接收基站广播的RRC配置信息。处理模块33，还用于根据所述RRC配置信息进行RRC配置，从而使用户设备可以进行后续接入流程。也就是说，本实施例中，将基站和用户设备之间的RRC配置信息交互从基站和每个用户设备之间单独发送的方式改为了基站向所有用户设备同时广播。这样节约了基站和用户设备之间进行RRC配置信息的交互所需的时间以及通信资源，使图3所示实施例的用户设备更加适用于应急通信。
进一步地，图3所示实施例的基站中，接收模块32，还用于在发送模块31向基站发送上行业务请求信息之前，接收所述基站广播的应急通信指示信息；处理模块33，还用于在所述接收模块接收到所述应急通信指示信息后，确定所述基站处于应急通信模式；发送模块31，具体用于当处理模块33确定所述基站处于应急通信模式时，向所述基站发送所述上行业务请求信息，并在所述上行业务请求信息中携带所述业务类型信息。
具体地，由于图3所示实施例的用户设备是要进行应急通信，而在正常的非应急通信中，用户设备不会在向基站发送上行业务请求消息时携带业务类型信息。因此，图3所示实施例的用户设备中，接收模块32，还用于在发送模块31向基站发送上行业务请求信息之前，接收所述基站广播的应急通信指示信息。当接收模块32接收到基站广播的应急通信指示信息后，处理模块33即可确定基站处于应急通信模式。然后发送模块31才在向基站发送的上行业务请求信息中携带业务类型信息。
进一步地，图3所示实施例的用户设备中，接收模块32，还用于在发送模块31向基站发送上行业务请求信息之前，接收所述基站广播的支持的业务类型信息；发送模块31，还用于在接收模块32接收到所述基站广播的支持的业务类型信息后，向基站发送上行业务请求信息，所述上行业务请求信息中包括业务类型信息，所述业务类型信息包括所述基站支持的业务类型信息。
具体地，在图3所示实施例的用户设备进行应急通信时，提供应急通信服务的基站为了尽可能地保证更多的用户设备传输上行业务数据，该基站需要根据自身的能力或需要提供应急通信服务的区域的用户数量确定能够支持 的业务类型信息。例如；若基站提供的接入能力较强或者需要提供应急通信的区域中用户数量较少，则基站可以支持文本类、语音类以及视频类业务，若基站提供的接入能力较弱或者需要提供应急通信的区域中用户数量较多，则基站可以仅支持文本类业务或者仅支持文本类和语音类业务。为了使需要进行应急通信区域的用户设备获知基站所支持的业务类型信息，基站会广播支持的业务类型信息，因此接收模块32，还用于在发送模块31向基站发送上行业务请求信息之前，接收所述基站广播的支持的业务类型信息。从而可以使用户设备获知基站支持的业务类型信息。当发送模块31向基站发送上行业务请求信息，即可仅在业务类型信息包括基站支持的业务类型信息。
进一步地，图3所示实施例的用户设备中，发送模块31，还用于在向基站发送上行业务请求信息之前，向所述基站发送随机接入请求消息；接收模块32，还用于在发送模块31向所述基站发送所述随机接入请求消息后，接收所述基站发送的随机接入响应消息。
具体地，用户设备接入未知的基站之前，还需要向基站发送随机接入请求消息，当用户设备接收到基站反馈的随机接入响应消息后，才能继续进行接入流程。因此，图3所示的用户设备中，发送模块31，还用于在向基站发送上行业务请求信息之前，向所述基站发送随机接入请求消息；接收模块32，还用于接收所述基站发送的随机接入响应消息。当接收模块32接收到基站发送的随机接入响应消息后，用户设备才能进行后续接入流程。
图4为本发明实施例提供的应急通信方法实施例一的流程图，如图4所示，本实施例的方法包括：
步骤S401，用户设备向基站发送上行业务请求信息，所述上行业务请求信息中包括业务类型信息。
具体地，用户设备向基站发送上行业务请求消息的同时，还可以发送用户设备的标识信息，该标识信息可以是能够表征用户设备身份信息的任一种信息，例如国际移动用户识别码(International Mobile Subscriber Identification Number，IMSI)等。用户设备向基站发送的业务类型信息包括业务类型和/或业务数据大小。业务类型包括文本类、语音类、视频类中的任意一项。
步骤S402，基站根据所述业务类型信息为用户设备分配上行资源。
具体地，基站在接收到用户设备发送的上行业务请求消息后，根据业务 类型信息分配上行资源。当业务类型信息为业务类型时，基站可以首先根据不同的业务类型确定是否为用户设备分配上行资源。由于用户设备传输视频类数据所需的上行资源大于传输语音类数据所需的上行资源，传输语音类数据所需的上行资源大于传输文本类数据所需的上行资源，而在进行应急通信时，通信资源一般较为有限，因此可能仅允许接入的用户设备发送文本类的上行数据，或仅允许接入的用户设备发送文本类或语音类的上行数据等，避免一个用户占用过多的通信资源而导致其他用户设备无法进行应急通信。当业务类型信息为业务数据大小时，基站即可根据业务数据大小为用户设备分配相应的上行资源。或者基站中还可以预设有不同业务类型所对应的上行资源大小，当业务类型信息为业务类型时，基站即可根据业务类型为用户设备分配相应的上行资源。
步骤S403，所述基站向所述用户设备发送上行业务请求应答消息，所述上行业务请求应答消息携带所述分配的上行资源的指示信息。
具体地，基站下向用户设备发送上行业务请求应答消息时，即向用户设备指示了为其分配的上行资源。
步骤S404，所述基站接收所述用户设备发送的上行业务数据，所述上行业务数据是所述用户设备在所述指示信息所指示的上行资源上发送的。
步骤S405，基站向用户设备发送应答确认消息并释放所述上行资源。
具体地，当基站向用户设备发送应答确认消息的同时，基站即可释放为用户设备分配的上行资源。

步骤S503，基站广播应急通信指示信息。
步骤S504，基站广播支持的业务类型信息。
具体地，步骤S501至步骤S504的执行顺序没有先后之分。基站在用户设备接入之前广播各类信息即可。或者在用户设备中可以预设步骤S501至步骤S504中基站需要广播的信息，则用户设备也可以在基站未广播上述信息之前接入基站。
步骤S505，用户设备根据所述RRC配置信息进行RRC配置。
步骤S506，用户设备根据应急通信指示信息确定基站处于应急通信模式。
