Description

一种数据传输方法、装置及***
本申请要求于2015年04月27日提交中国专利局、申请号为PCT/CN2015/077525、发明名称为“一种数据传输方法、装置及***”的PCT专利申请的优先权，其全部内容通过引用结合在本申请中。
技术领域
本发明涉及通信领域，尤其涉及一种数据传输方法、装置及***。
背景技术
随着机器到机器(英文：machine to machine，缩写：M2M)***的广泛应用，包含数据量较小的小数据包的传输越来越多，例如，M2M***应用于智能抄表、智能交通以及智能医疗等时，终端与基站之间传输的数据包均为小数据包。
通常，在长期演进(英文：long term evolution，缩写：LTE)***中，终端无数据传输时一般处于空闲态(英文：idle)，即终端与基站之间无无线资源控制(英文：radio resource control，缩写：RRC)连接。当处于空闲态的终端需要传输数据时，在终端向基站发送数据包之前，终端首先需要与基站之间建立RRC连接，即终端从空闲态切换到连接态。为了节省传输资源，当终端无数据传输时，终端会释放终端与基站之间的RRC连接，即终端从连接态切换到空闲态。
当上述数据传输流程应用于M2M***时，由于终端需要发送的数据包为小数据包且数据包的数量较多，因此终端需要频繁地与基站之间建立RRC连接和释放RRC连接，从而导致这些小数据包的传输效率较低。

具体实施方式
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，所描述的实施例仅仅是本发明的一部分实施例，而不是全部的实施例。
本发明实施例提供的数据传输方法、装置及***可以应用于处于空闲态的终端和基站之间需要进行数据传输的数据传输***中，例如该数据传输***可以为M2M***。其中，本发明实施例中，处于空闲态的终端和基站之间传输数据时，不再需要建立RRC连接，而是可以直接传输数据包。
需要说明的是，本发明实施例中的空闲态可以理解为终端和基站之间没有建立RRC连接的状态；该空闲态也可以理解为终端广义的无特定状态，即在该特定状态下终端和基站之间没有建立RRC连接，但是获得了一部分接入层资源，比如终端获得了接入网设备为终端分配的接入层标识等；该空闲态也可以理解为终端和基站之间没有该终端专用的数据发送资源的状态；该空闲态还可以理解为终端和基站之间进行过数据传输，但是已经长时间(例如几十分钟，几个小时、甚至几天等)没有进行数据传输的状态，该状态也可以称为不活动态。
可选的，该空闲态也可以理解为终端不进行下行导频测量的节电状态；该空闲态还可以理解为终端有在多个小区范围内共享的唯一的空口标识的一个状态，例如终端有在多个小区范围内共享的唯一的无线网络临时标识(radio network temporary identifier，缩写：RNTI)的一个状态。为了下述描述方便，终端在多个小区范围内共享的唯一的RNTI可以表示为X-RNTI。
特别的，上述直接传输的数据包可以为应用层生成的数据包，即称为应用层数据包，例如互联网协议(Internet protocol，缩写：IP)数据包。
可选的，上述直接传输的数据包还可以为信令数据包、媒体接入控制(英文：media access control，缩写：MAC)层控制包或者物理层序列。信令数据包可以包括接入层(英文：access stratum，缩写：AS)数据包或非接入层(英文：non access stratum，缩写：NAS)数据包。
如图1所示，为本发明实施例提供的数据传输***的架构图。在该数据传输***中，终端与基站之间传输的应用层数据包通常为数据量较小或者发送间隔较大(其中，数据量较小可以理解为终端待发送数据量小于或等于第一门限；发送间隔较大可以理解为终端待发送上行应用层数据包之间的发送间隔大于或等于第二门限)的应用层数据包。如果按照现有技术的数据传输方法，为了节省终端与基站之间的空口资源，终端没有数据传输时一般处于空闲态(即将处于连接态时建立的RRC连接释放)。当处于空闲态的终端有数据传输时，终端会先发起RRC连接，从而在终端与基站之间建立RRC连接，即终端从空闲态切换到连接态之后，终端才可以与基站之间进行数据传输；当处于连接态的终端在一段时间内没有数据传输时，终端会将终端与基站之间的RRC连接释放，即终端从连接态切换到空闲态。如此，当终端需要发送数据量较小或者发送间隔较大的应用层数据包时，终端需要与基站之间频繁地建立RRC连接和释放RRC连接，即当处于空闲态的终端需要发送应用层数据包时，终端首先需要与基站之间建立RRC连接，然后才能传输应用层数据包，从而导致数据包的传输效率较低。
通过本发明实施例提供的数据传输方法，处于空闲态的终端与基站之间无需建立RRC连接，就可以直接传输应用层数据包，从而能够提高数据包的传输效率。
下面结合附图对本发明实施例提供的数据传输方法、装置及***进行详细地说明。其中，本发明实施例提供的数据传输方法中涉及的终端均为处于空闲态的终端。为了描述方便，以下实施例，尤其是方法步骤中的终端均省略了处于空闲态的限定，但是以下实施 例中提到的终端，无论明确指出是处于空闲态的终端还是未指出是处于空闲态的终端，均是指处于空闲态的终端。
实施例一

S101、终端接收基站发送的第一资源信息，第一资源信息用于终端向基站发送上行应用层数据包。
S102、终端在该第一资源信息上，向基站发送该上行应用层数据包。
本发明实施例提供的数据传输方法中，由于第一资源信息用于处于空闲态的终端向基站发送上行应用层数据包，因此，处于空闲态的终端接收到基站发送的第一资源信息之后，该终端可在该第一资源信息上直接向基站发送上行应用层数据包，即基站可在该第一资源信息上接收终端发送的上行应用层数据包。其中，该上行应用层数据包可以为终端需要发送给基站的用户数据，例如上行IP数据包。
可选的，上述第一资源信息可以是基站通过***广播消息广播的，也可以是基站通过专用消息发送给终端的，本发明不作具体限定。
可选的，上述第一资源信息也可以是在协议中定义的。
可选的，上述第一资源信息的数量可以为多个，从而能够保证多个处于空闲态的终端大部分都能成功向基站发送上行应用层数据包。
进一步地，当第一资源信息的数量有多个时，在上述S102之前，终端需先从多个第一资源信息中选择一个第一资源信息；相应的，在S102中，终端在选择的该一个第一资源信息上，向基站发送上行应用层数据包。

示例性的，终端根据该终端的标识从多个第一资源信息中选择一个第一资源信息的方法为：假设终端的标识为A，则终端可以用A模一个数(该数可以根据实际情况选择，例如为B，则终端可以用A％B，并根据模的结果，从多个第一资源信息中选择一个资源标识与该结果相同的第一资源信息。
终端根据基站为该终端进行的分组从多个第一资源信息中选择一个第一资源信息的方法为：假设基站将全部终端分为3个组，将多个第一资源信息也分为3个组，若该终端在第1组，则该终端可以从3组第一资源信息中选择第1组第一资源信息。
可选的，终端还可以从基站广播的***广播消息中获得用于发送上行应用层数据包的上行信道的配置信息；终端也可以从基站广播的***广播消息中获得用于接收下行应用层数据包的下行信道的配置信息。
可选的，上述第一资源信息可以为时频资源信息，例如时域资源信息和频域资源信息；上述第一资源信息还可以为时间资源信息，例如帧号和子帧号，具体的可以根据实际使用需求进行设计，本发明不作限定。
本发明实施例提供一种数据传输方法，该方法为处于空闲态的终端接收基站发送的第一资源信息，该第一资源信息用于该终端向基站发送上行应用层数据包；且该终端在该第一资源信息上，向基站发送上行应用层数据包。基于上述技术方案，当处于空闲态的终端需要发起数据传输时，该终端可以在基站发送的用于发送上行应用层数据包的第一资源信息上向基站发送上行应用层数据包，从而发起数据传输。本发明实施例中，终端发起数据传输之后，终端与 基站之间可以直接传输数据包，并不需要像现有技术中终端与基站之间传输数据包时会频繁地建立RRC连接和释放RRC连接，因此能够提高数据包的传输效率。
可选的，上述如图2所示的实施例中，上述专用消息可以为专用高层消息或者物理层调度信令。即上述第一资源信息是基站通过专用高层消息或物理层调度信令发送给终端的。
如图3所示，本发明实施例提供一种数据传输方法，该数据传输方法可以包括：
S201、基站发送第一资源信息，第一资源信息用于终端向基站发送上行应用层数据包。
S202、基站在第一资源信息上，接收终端发送的上行应用层数据包。
基站发送用于处于空闲态的终端发送上行应用层数据包的第一资源信息后，若某个处于空闲态的终端需要向基站发送上行应用层数据包，则该终端可以在该第一资源信息上向基站发送上行应用层数据包。
需要说明的是，对于第一资源信息和上行应用层数据包的描述具体可参见上述如图2所示的实施例中对第一资源信息和上行应用层数据包的相关描述，此处不再赘述。
本发明实施例提供一种数据传输方法，该方法为基站发送第一资源信息，第一资源信息用于处于空闲态的终端向基站发送上行应用层数据包；且基站在第一资源信息上，接收终端发送的上行应用层数据包。基于上述技术方案，当处于空闲态的终端需要发起数据传输时，该终端可以在基站发送的用于发送上行应用层数据包的第一资源信息上向基站发送上行应用层数据包，从而发起数据传输。本发明实施例中，终端发起数据传输之后，终端与基站之间可以直接传输数据包，并不需要像现有技术中终端与基站之间传输数据包时会频繁地建立RRC连接和释放RRC连接，因此能够提高数据包的传输效率。
可选的，上述如图2和图3所示的实施例中，上行应用层数据包可以被替换为上行信令数据包、上行MAC层控制包或者上行物理层序列。其中，对于上行应用层数据包、上行信令数据包、上行MAC层控制包以及上行物理层序列的描述及举例具体可以参见发明内容部分的相关描述(具体可参见发明内容部分位于第七方面之前的一些可选方式中的相关描述)，此处不再赘述。
可选的，本发明实施例中，终端可以通过需要发送的数据包所在的逻辑信道和/或目的地址等信息，指示基站要转发该数据包的目的网络节点，其中，该目的网络节点可以是基站控制节点或核心网节点。
可选的，本发明实施例中，基站、基站控制节点或核心网节点均可以为终端分配NAS的用户临时标识。
本发明实施例的数据传输方法，由于处于空闲态的终端和基站之间可以传输多种数据包(例如应用层数据包、信令数据包、MAC层控制包和物理层序列)，因此能够使得终端更加方便、灵活地发起数据传输，从而使得终端和基站之间可以更加方便、灵活地直接传输数据包，提高数据包的传输效率。
如图4所示，本发明实施例提供一种数据传输方法，该数据传输方法可以包括：
S301、终端接收基站发送的下行控制信息，下行控制信息中包含数据传输指示，数据传输指示用于指示终端接收基站发送的下行应用层数据包。
S302、终端根据该数据传输指示，接收基站发送的下行应用层数据包。
本发明实施例提供的数据传输方法中，处于空闲态的终端可以根据基站发送的下行控制信息中的数据传输指示接收基站发送的下行应用层数据包。具体的，处于空闲态的终端接收到基站发送的下行控制信息后，该终端根据下行控制信息中的数据传输指示确定基站指示该终端接收基站发送的下行应用层数据包，从而该终端可根 据该数据传输指示，在下行控制信息指示的资源上接收基站发送的下行应用层数据包，即该终端和基站之间可以直接进行数据传输。
具体的，基站可以通过物理下行控制信道(英文：physical downlink control channel，缩写：PDCCH)向终端发送下行控制信息；从而终端也可以通过监听PDCCH接收基站发送的下行控制信息。
本发明实施例提供一种数据传输方法，该方法为处于空闲态的终端接收基站发送的下行控制信息，该下行控制信息中包含数据传输指示，该数据传输指示用于指示该终端接收基站发送的下行应用层数据包；且该终端根据该数据传输指示，接收基站发送的下行应用层数据包。基于上述技术方案，由于基站可以通过数据传输指示指示处于空闲态的终端接收基站发送的下行应用层数据包，因此该终端可以根据该数据传输指示直接接收基站发送的下行应用层数据包，从而发起数据传输。本发明实施例中，终端发起数据传输之后，终端与基站之间可以直接传输数据包，并不需要像现有技术中终端与基站之间传输数据包时会频繁地建立RRC连接和释放RRC连接，因此能够提高数据包的传输效率。
如图5所示，本发明实施例提供一种数据传输方法，该数据传输方法可以包括：
S401、基站向终端发送下行控制信息，该下行控制信息中包含数据传输指示，该数据传输指示用于指示终端接收基站发送的下行应用层数据包。
S402、基站向终端发送下行应用层数据包。
本发明实施例提供的数据传输方法中，当基站需要向处于空闲态的终端发送下行应用层数据包时，基站可以在PDCCH上向该终端发送下行控制信息，该下行控制信息中包含用于指示该终端接收基站发送的下行应用层数据包的数据传输指示，从而该终端可根据该数据传输指示接收基站发送的下行应用层数据包，即该终端和基站之间可以直接进行数据传输。
具体的，基站可以通过PDCCH向终端发送下行控制信息；从 而终端也可以通过监听PDCCH接收基站发送的下行控制信息。
本发明实施例提供一种数据传输方法，该方法为基站向处于空闲态的终端发送下行控制信息，该下行控制信息中包含数据传输指示，该数据传输指示用于指示该终端接收基站发送的下行应用层数据包；且基站向该终端发送下行应用层数据包。基于上述技术方案，由于基站可以通过数据传输指示指示处于空闲态的终端接收基站发送的下行应用层数据包，因此该终端可以根据该数据传输指示直接接收基站发送的下行应用层数据包，从而发起数据传输。本发明实施例中，终端发起数据传输之后，终端与基站之间可以直接传输数据包，并不需要像现有技术中终端与基站之间传输数据包时会频繁地建立RRC连接和释放RRC连接，因此能够提高数据包的传输效率。
可选的，上述如图4和图5所示的实施例中的下行控制信道可以是不同于现有技术的PDCCH的一条信道。例如通过另外一段资源发送上述下行控制信息(以下简称第一下行控制信息)，该另外一段资源即为上述的下行控制信道，且该第一下行控制信息所占的比特也较现有技术的下行控制信息所占的比特少(即该第一下行控制信息的内容较现有技术的下行控制信息的内容少)。例如，该第一下行控制信息只包括终端的标识和/或下行数据信道的无线资源信息。
可选的，上述如图4和图5所示的实施例中，下行应用层数据包可以被替换为下行信令数据包、下行MAC层控制包或者下行物理层序列。其中，对于下行应用层数据包、下行信令数据包、下行MAC层控制包以及下行物理层序列的描述及举例具体可以参见发明内容部分的相关描述(具体可参见发明内容部分位于第七方面之后，且位于第十三方面之前的一些可选方式中的相关描述)，此处不再赘述。
本发明实施例的数据传输方法，由于处于空闲态的终端和基站之间可以传输多种数据包(例如应用层数据包、信令数据包、MAC层控制包和物理层序列)，因此能够使得终端更加方便、灵活地发起 数据传输，从而使得终端和基站之间可以更加方便、灵活地直接传输数据包，提高数据包的传输效率。
实施例二
本发明实施例提供的数据传输方法，一种可能的实现方式中，终端不用接入基站，即终端不用请求基站为终端分配用于发送上行应用层数据包的第一资源信息，基站就可以直接为终端分配该第一资源信息，从而终端可在该第一资源信息上向基站发送上行应用层数据包；另一种可能的实现方式中，终端需先接入基站，即终端需先向基站请求用于发送上行应用层数据包的第一资源信息，然后基站才能为终端分配该第一资源信息，从而终端才可以在该第一资源信息上向基站发送上行应用层数据包。
为了更好地理解本发明实施例提供的数据传输方法，下面分别以上述两种可能的实现方式为例，对本发明实施例提供的数据传输方法进行详细地描述。
一种可能的实现方式：终端不用接入基站
如图6所示，本发明实施例提供一种数据传输方法，该数据传输方法可以包括：
S501、基站发送第一资源信息，该第一资源信息用于终端向基站发送上行应用层数据包。
S502、终端在该第一资源信息上，向基站发送该上行应用层数据包。
本发明实施例提供的数据传输方法中，由于第一资源信息用于处于空闲态的终端向基站发送上行应用层数据包，因此，处于空闲态的终端接收到基站发送的第一资源信息之后，该终端可在该第一资源信息上直接向基站发送上行应用层数据包，即基站可在该第一资源信息上接收终端发送的上行应用层数据包。其中，该上行应用层数据包可以为终端需要发送给基站的用户数据，例如上行IP数据包。
可选的，基站可以通过接收或者拒绝接收终端发送的上行应用 层数据包的方式响应该终端。若基站接收终端发送的上行应用层数据包，则基站与终端之间可以直接进行数据传输；若基站拒绝接收终端发送的上行应用层数据包，则基站可指示该终端发起RRC连接建立过程，并在建立RRC连接后再通过现有技术中的数据传输方式进行数据传输，此处不再赘述。
进一步地，若基站接收终端发送的上行应用层数据包，则基站还可以为该终端分配一个标识，并指示该终端保存该标识。该标识可以为终端的小区级标识，例如可以为终端的小区无线网络临时标识(英文：cell radio network temporary identifier，缩写：C-RNTI)。该标识可用于基站向该终端发送下行应用层数据包。
其中，当终端中已经保存了终端的C-RNTI时，若基站为终端分配新的C-RNTI，则终端可以更新终端中保存的C-RNTI。
示例性的，终端首次驻留一个小区或者进行小区重选后，终端可通知为其提供服务的基站为其分配新的C-RNTI，终端接收到基站为其分配的新的C-RNTI后，终端保存该新的C-RNTI或者采用该新的C-RNTI覆盖旧的C-RNTI(旧的C-RNTI可以理解为终端在接收到新的C-RNTI之前保存的C-RNTI)；且终端也可以通知原来为其提供服务的基站释放旧的C-RNTI。
其中，终端通知原来为其提供服务的基站释放旧的C-RNTI的方法可以为：终端可以周期性地向基站发送在网指示消息，该在网指示消息用于指示终端在基站的覆盖范围内，若基站在某个预设时间，例如24小时内未接收到终端发送的该在网指示消息，则基站可认为该终端已经不在其覆盖范围内了，从而基站可以释放其为该终端分配的C-RNTI。
上述S502中，终端在第一资源信息上，向基站发送上行应用层数据包时，可以在该上行应用层数据包中携带该终端的IP地址、该终端的C-RNTI或该终端的其他标识，该终端的其他标识可以为核心网设备为该终端分配的唯一标识，比如该终端的***架构演进临时移动身份标识(英文：system architecture evolution temporary  mobile station identifier，缩写：S-TMSI)等。该终端也可以在该上行应用层数据包的媒体接入控制(英文：media access control，缩写：MAC)头中携带该终端的IP地址、该终端的C-RNTI或该终端的其他标识。具体的，本发明不作限定。其中，该上行应用层数据包可以为上行IP数据包。
进一步地，当该上行应用层数据包或该上行应用层数据包的MAC头中携带该终端的IP地址，或者该上行应用层数据包或该上行应用层数据包的MAC头中携带该终端的其他标识时，基站接收到该终端发送的上行应用层数据包之后，基站可建立基站为该终端分配的标识和该上行应用层数据包中携带的该终端的标识之间的对应关系，从而便于基站在向该终端发送下行应用层数据包时，可以准确地将下行应用层数据包发送给该终端。
例如，若基站为该终端分配的标识为该终端的C-RNTI，上行应用层数据包中携带的该终端的标识为该终端的IP地址或该终端的S-TMSI，则基站接收到上行应用层数据包之后，基站可建立该终端的C-RNTI和该终端的IP地址之间的对应关系，或者建立该终端的C-RNTI和该终端的S-TMSI之间的对应关系。从而便于基站在向终端发送下行应用层数据包时，可以准确地将下行应用层数据包发送给终端。
进一步地，本发明实施例提供的数据传输方法中，基站接收到终端在第一资源信息上发送的上行应用层数据包后，基站可以直接通过提前约定或新建的一个公共隧道将该上行应用层数据包发送到网关，基站也可以直接将该上行应用层数据包发送到分组数据网络(英文：packet data network缩写：PDN)，本发明不作具体限定。
可选的，上述第一资源信息可以是基站通过***广播消息广播的，也可以是基站通过专用消息发送给终端的，本发明不作具体限定。
可选的，上述第一资源信息也可以是在协议中定义的。
可选的，上述第一资源信息的数量可以为多个，从而能够保证 多个处于空闲态的终端大部分都能成功向基站发送上行应用层数据包。
进一步地，当第一资源信息的数量有多个时，在上述S502之前，终端需先从多个第一资源信息中选择一个第一资源信息；相应的，在S502中，终端在选择的该一个第一资源信息上，向基站发送上行应用层数据包。
需要说明的是，对于第一资源信息、第一资源信息的数量以及基站发送第一资源信息的方式的其他描述具体可参见上述如图2所示的实施例中对第一资源信息、第一资源信息的数量以及基站发送第一资源信息的方式的相关描述，此处不再赘述。
可选的，上述S502，终端在该第一资源信息上，向基站发送该上行应用层数据包之前，终端需要先判断其是否需要在该第一资源信息上向基站发送上行应用层数据包，即上述S502的触发条件可以为下述的一种：
(1)当处于空闲态的终端待发送数据量小于或等于第一门限时，终端在该第一资源信息上，向基站发送该上行应用层数据包。
(2)当处于空闲态的终端待发送上行应用层数据包之间的发送间隔大于或等于第二门限时，终端在该第一资源信息上，向基站发送该上行应用层数据包。
其中，上述第一门限的取值和第二门限的取值可以根据实际的数据传输需求进行设置，本发明不作具体限定。
具体的，处于空闲态的终端判断其是否需要在该第一资源信息上向基站发送上行应用层数据包的触发条件可以根据实际需求进行设计，本发明不作限定。
可选的，终端可在上述S502中指示终端待发送数据量(比如可以用缓存状态报告(英文：buffer status report，缩写：BSR)指示)或者终端待发送上行应用层数据包之间的发送间隔，以便于基站根据终端待发送数据量或者终端待发送上行应用层数据包之间的发送间隔确定是否需要接收终端发送的上行应用层数据包。
可选的，终端还可以从基站广播的***广播消息中获得用于发送上行应用层数据包的上行信道的配置信息；终端也可以从基站广播的***广播消息中获得用于接收下行应用层数据包的下行信道的配置信息。
可选的，结合图6，如图7所示，在S502，即终端在该第一资源信息上，向基站发送该上行应用层数据包之后，本发明实施例提供的数据传输方法还可以包括：
S503、基站向终端发送下行应用层数据包或者下行控制信息，下行应用层数据包或者下行控制信息中包含第一终端的标识，第一终端的标识用于指示基站成功接收第一终端发送的第一上行应用层数据包。
S504、终端根据第一终端的标识，确定基站是否成功接收该终端发送的上行应用层数据包。
由于可能会有两个或两个以上处于空闲态的终端同时在第一资源信息上向基站发送上行应用层数据包，因此基站可能只会成功接收其中一个终端发送的上行应用层数据包。为了使得终端能够获知其发送的上行应用层数据包是否发送成功，基站在接收到某个上行应用层数据包之后，基站可在共享信道上发送一个下行应用层数据包或者下行控制信息，该下行应用层数据包或者下行控制信息中包含第一终端的标识，该第一终端为基站成功接收上行应用层数据包的终端，该第一终端的标识可用于指示基站成功接收上行应用层数据包的终端。其中，基站向终端发送的下行应用层数据包可以是终端向基站发送的上行应用层数据包或该上行应用层数据包的一部分。当采用该共享信道与基站进行数据传输的终端接收到基站发送的该下行应用层数据包或者下行控制信息之后，这些终端可根据该下行应用层数据包或者下行控制信息中包含的第一终端的标识，确定基站是否成功接收其发送的上行应用层数据包。从而使得确定基站没有成功接收其发送的上行应用层数据包的终端可以再次发送上行应用层数据包，或者采用现有的传输方式建立RRC连接后再发送 上行应用层数据包。
示例性的，若该下行应用层数据包或者下行控制信息中包含的第一终端的标识为本发明实施例中的终端的标识，则该终端接收到该下行应用层数据包或者下行控制信息之后，该终端可确定基站成功接收其发送的上行应用层数据包。
具体的，基站可以通过PDCCH向终端发送下行控制信息；从而终端也可以通过监听PDCCH接收基站发送的下行控制信息。
本发明实施例提供一种数据传输方法，该方法为处于空闲态的终端接收基站发送的第一资源信息，该第一资源信息用于该终端向基站发送上行应用层数据包；且该终端在该第一资源信息上，向基站发送上行应用层数据包。基于上述技术方案，当处于空闲态的终端需要发起数据传输时，该终端可以在基站发送的用于发送上行应用层数据包的第一资源信息上向基站发送上行应用层数据包，从而发起数据传输。本发明实施例中，终端发起数据传输之后，终端与基站之间可以直接传输数据包，并不需要像现有技术中终端与基站之间传输数据包时会频繁地建立RRC连接和释放RRC连接，因此能够提高数据包的传输效率。
另一种可能的实现方式：终端需要接入基站
在这种可能的实现方式中，终端接入基站时可以向基站请求用于发送上行应用层数据包的第一资源信息。具体的，终端可以通过发送接入序列的接入资源信息向基站请求用于发送上行应用层数据包的第一资源信息；终端也可以通过其发送的接入序列向基站请求用于发送上行应用层数据包的第一资源信息。下面分别对这种情况进行详细地说明。
情况一：终端通过发送接入序列的接入资源信息向基站请求用于发送上行应用层数据包的第一资源信息
如图8所示，本发明实施例提供一种数据传输方法，该数据传输方法可以包括：
S601、终端在接入资源信息上，向基站发送接入序列，该接入 资源信息用于请求基站为终端分配第一资源信息，该第一资源信息用于终端向基站发送上行应用层数据包。
S602、基站根据该接入资源信息，为终端分配该第一资源信息。
S603、基站向终端发送该第一资源信息。
S604、终端在该第一资源信息上，向基站发送该上行应用层数据包。
其中，上述S601中的接入资源信息和接入序列可以是基站通过***广播消息广播的。本实施例中，接入资源信息可以用于处于空闲态的终端请求基站为该终端分配用于发送上行应用层数据包的资源信息，即第一资源信息。基站接收到处于空闲态的终端在该接入资源信息上发送的接入序列后，基站可为该终端分配该第一资源信息，以使得处于空闲态的终端可以直接在该第一资源信息上向基站发送上行应用层数据包。
本发明实施例提供的数据传输方法中，处于空闲态的终端可以通过接入资源信息(本实施例中的接入资源信息可以为终端发起随机接入的资源信息)请求基站为该终端分配用于发送上行应用层数据包的第一资源信息。
由于本实施例中的接入资源信息可以用于处于空闲态的终端向基站请求用于发送上行应用层数据包的第一资源信息，因此本实施例中的接入资源信息可以通过在普通的接入资源信息中增加一个字段实现，其中，该字段标识该接入资源信息可以用于终端向基站请求用于发送上行应用层数据包的第一资源信息；本实施例中的接入资源信息也可以通过单独设计一种新的接入资源信息实现，该新的接入资源信息可以用于终端向基站请求用于发送上行应用层数据包的第一资源信息，其中，该新的接入资源信息的结构可以与普通的接入资源信息的结构相同。
特别的，上述普通的接入资源信息可以为通常情况下终端进行随机接入，即终端发送接入序列的接入资源信息。
需要说明的是，本实施例中，终端在接入资源信息上向基站发 送的接入序列可以为普通的接入序列，例如该接入序列可以为通常情况下终端进行随机接入的接入序列。
可选的，该接入资源信息可以为时频资源信息，例如时域资源信息和频域资源信息；该接入资源信息还可以为时间资源信息，例如帧号和子帧号，具体的可以根据实际使用需求进行设计，本发明不作限定。
可选的，上述接入资源信息可以是基站通过***广播消息广播的，也可以是基站通过专用消息发送给终端的，还可以是在协议中定义的，本发明不作具体限定。
可选的，上述接入资源信息的数量可以为多个，从而能够保证多个处于空闲态的终端大部分都能成功接入基站，并向基站请求用于发送上行应用层数据包的第一资源信息。
进一步地，当接入资源信息的数量有多个时，在上述S601之前，终端需先从多个接入资源信息中选择一个接入资源信息；相应的，在S601中，终端在选择的该一个接入资源信息上，向基站发送接入序列。
其中，终端可以采用随机选择的方式从多个接入资源信息中选择一个接入资源信息；终端可以根据该终端的标识从多个接入资源信息中选择一个接入资源信息；终端也可以根据基站为该终端分的组从多个接入资源信息中选择一个接入资源信息；终端还可以采用其他方式从多个接入资源信息中选择一个接入资源信息，具体的选择方式本发明不作限定。
需要说明的是，终端根据该终端的标识从多个接入资源信息中选择一个接入资源信息的方法与上述终端根据该终端的标识从多个第一资源信息中选择一个第一资源信息的方法类似；终端根据基站为该终端分的组从多个接入资源信息中选择一个接入资源信息的方法与上述终端根据基站为该终端分的组从多个第一资源信息中选择一个第一资源信息的方法类似，具体可参见上述如图2所示的实施例中的相关描述，此处不再赘述。
可选的，上述S601，终端在接入资源信息上，向基站发送接入序列之前，终端需要先判断其是否需要向基站请求用于发送上行应用层数据包的第一资源信息，即上述S601的触发条件可以为下述的一种：
(1)当处于空闲态的终端待发送数据量小于或等于第一门限时，终端在接入资源信息上，向基站发送接入序列。
(2)当处于空闲态的终端待发送上行应用层数据包之间的发送间隔大于或等于第二门限时，终端在接入资源信息上，向基站发送接入序列。
其中，上述第一门限的取值和第二门限的取值可以根据实际的数据传输需求进行设置，本发明不作具体限定。
具体的，处于空闲态的终端判断其是否需要向基站请求用于发送上行应用层数据包的第一资源信息的触发条件可以根据实际需求进行设计，本发明不作限定。
可选的，基站可以通过接受或者拒绝为该终端分配用于发送上行应用层数据包的第一资源信息的方式响应该终端。若基站接受为该终端分配第一资源信息，则基站可以直接为终端分配第一资源信息，即终端可以在第一资源信息上直接向基站发送上行应用层数据包；若基站拒绝为该终端分配第一资源信息，则基站可指示该终端发起RRC连接建立过程，并在建立RRC连接后再通过现有技术中的数据传输方式进行数据传输，此处不再赘述。
可选的，若基站接受为该终端分配第一资源信息，则基站还可以为该终端分配一个标识，并指示该终端保存该标识。该标识可以为该终端的小区级标识，例如可以为该终端的C-RNTI。该标识可用于基站向该终端发送下行应用层数据包。
其中，当终端中已经保存了终端的C-RNTI时，若基站为终端分配新的C-RNTI，则终端可以更新终端中保存的C-RNTI。
示例性的，终端首次驻留一个小区或者进行小区重选后，终端可通知为其提供服务的基站为其分配新的C-RNTI，终端接收到基站 为其分配的新的C-RNTI后，终端保存该新的C-RNTI或者采用该新的C-RNTI覆盖旧的C-RNTI(旧的C-RNTI可以理解为终端在接收到新的C-RNTI之前保存的C-RNTI)；且终端也可以通知原来为其提供服务的基站释放旧的C-RNTI。
其中，终端通知原来为其提供服务的基站释放旧的C-RNTI的方法可以为：终端可以周期性地向基站发送在网指示消息，该在网指示消息用于指示终端在基站的覆盖范围内，若基站在某个预设时间，例如24小时内未接收到终端发送的该在网指示消息，则基站可认为该终端已经不在其覆盖范围内了，从而基站可以释放其为该终端分配的C-RNTI。
上述S604中，终端在第一资源信息上，向基站发送上行应用层数据包时，可以在该上行应用层数据包中携带该终端的IP地址、该终端的C-RNTI或该终端的其他标识，该终端的其他标识可以为核心网设备为该终端分配的唯一标识，比如该终端的S-TMSI等。该终端也可以在该上行应用层数据包的MAC头中携带该终端的IP地址、该终端的C-RNTI或该终端的其他标识。具体的，本发明不作限定。其中，该上行应用层数据包可以为上行IP数据包。
进一步地，当该上行应用层数据包或该上行应用层数据包的MAC头中携带该终端的IP地址，或者该上行应用层数据包或该上行应用层数据包的MAC头中携带该终端的其他标识时，基站接收到该终端发送的上行应用层数据包之后，基站可建立基站为该终端分配的标识和该上行应用层数据包中携带的该终端的标识之间的对应关系。从而便于基站在向该终端发送下行应用层数据包时，可以准确地将下行应用层数据包发送给该终端。具体的，基站建立基站为该终端分配的标识和该上行应用层数据包中携带的该终端的标识之间的对应关系的描述可参见上述如图6所示的实施例中的相关描述，此处不再赘述。
进一步地，本发明实施例提供的数据传输方法中，基站接收到终端在第一资源信息上发送的上行应用层数据包后，基站可以直接 通过提前约定或新建的一个公共隧道将该上行应用层数据包发送到网关，基站也可以直接将该上行应用层数据包发送到PDN，本发明不作具体限定。
需要说明的是，对于第一资源信息、第一资源信息的数量以及基站发送第一资源信息的方式的描述具体可参见上述如图6所示的实施例中对第一资源信息、第一资源信息的数量以及基站发送第一资源信息的方式的相关描述，此处不再赘述。
可选的，本实施例中的第一资源信息可以为时频资源信息，例如时域资源信息和频域资源信息；该第一资源信息还可以为时间资源信息，例如帧号和子帧号，具体的可以根据实际使用需求进行设计，本发明不作限定。
可选的，终端可在上述S601或S604中指示终端待发送数据量(比如可以用BSR指示)或者终端待发送上行应用层数据包之间的发送间隔，以便于基站根据终端待发送数据量或者终端待发送上行应用层数据包之间的发送间隔确定是否需要为终端分配用于发送上行应用层数据包的第一资源信息。
可选的，当终端在上述S601中指示终端待发送数据量或者终端待发送上行应用层数据包之间的发送间隔时，在上述S603中，基站可根据终端待发送数据量指示终端可用的一段时间资源(即第一资源信息为一段时间资源)，比如多个传输时间间隔(英文：transmission time interval，缩写：TTI)；或者基站可根据终端待发送数据量指示终端可以使用第一资源信息的时间长度。这样可以使得终端在一段时间内不用再向基站请求发送上行应用层数据包的资源信息，从而可以提高数据发送效率。
可选的，终端还可以从基站广播的***广播消息中获得用于发送上行应用层数据包的上行信道的配置信息；终端也可以从基站广播的***广播消息中获得用于接收下行应用层数据包的下行信道的配置信息。
可选的，结合图8，如图9所示，在S604，即终端在该第一资 源信息上，向基站发送该上行应用层数据包之后，本发明实施例提供的数据传输方法还可以包括：
S605、基站向终端发送下行应用层数据包或者下行控制信息，下行应用层数据包或者下行控制信息中包含第一终端的标识，第一终端的标识用于指示基站成功接收第一终端发送的第一上行应用层数据包。
S606、终端根据第一终端的标识，确定基站是否成功接收该终端发送的上行应用层数据包。
对于S605-S606的描述具体可参见上述如图7所示的实施例中对S503-S504的相关描述，此处不再赘述。
示例性的，若该下行应用层数据包或者下行控制信息中包含的第一终端的标识为本发明实施例中的终端的标识，则该终端接收到该下行应用层数据包或者下行控制信息之后，该终端可确定基站成功接收其发送的上行应用层数据包。
具体的，基站可以通过PDCCH向终端发送下行控制信息；从而终端也可以通过监听PDCCH接收基站发送的下行控制信息。
本发明实施例提供一种数据传输方法，该方法为处于空闲态的终端在接入资源信息上，向基站发送接入序列，基站根据该接入资源信息为终端分配用于发送上行应用层数据包的第一资源信息，并将该第一资源信息发送给终端，以及终端在该第一资源信息上，向基站发送该上行应用层数据包。基于上述技术方案，当处于空闲态的终端需要发起数据传输时，该终端可以通过发送接入序列的接入资源信息向基站请求发送上行应用层数据包的第一资源信息，并在基站为终端分配第一资源信息后，终端在该第一资源信息上，向基站发送上行应用层数据包，从而发起数据传输。本发明实施例中，终端发起数据传输之后，终端与基站之间可以直接传输数据包，并不需要像现有技术中终端与基站之间传输数据包时会频繁地建立RRC连接和释放RRC连接，因此能够提高数据包的传输效率。

需要说明的是，终端确定下行控制信息的接收时机的标识与基站确定该下行控制信息的发送时机的标识相同。例如，若终端采用该终端的C-RNTI确定下行控制信息的接收时机，则基站也采用该终端的C-RNTI确定下行控制信息的发送时机；若终端采用该终端的IP地址确定下行控制信息的接收时机，则基站也采用该终端的IP地址确定下行控制信息的发送时机。
可选的，上述接收时机可以为时频资源信息，例如时域资源信 息和频域资源信息；也可以为时间资源信息，例如帧号和子帧号。相应的，发送时机也可以为时频资源信息或者时间资源信息。具体的可以根据实际使用需求进行设计，本发明不作限定。
可选的，终端可根据终端的标识和非连续接收(英文：discontinuous reception，缩写：DRX)周期确定下行控制信息的接收时机。基站也可根据终端的标识和DRX周期确定下行控制信息的发送时机。
示例性的，以终端的标识为终端的IP地址为例，终端可以根据该终端的IP地址和该终端的DRX周期计算下行控制信息的接收时机；同样，基站也可以根据该终端的IP地址和该终端的DRX周期计算下行控制信息的发送时机。
具体的，上述S805中，基站可以通过PDCCH向终端发送下行控制信息；从而终端也可以通过监听PDCCH接收基站发送的下行控制信息。
可选的，本发明实施例提供的数据传输方法中，基站可采用终端的标识，例如终端的IP地址调度该终端。具体的，以终端的IP地址为例，基站可在下行控制信息中携带该终端的IP地址，当该终端接收到下行控制信息后，该终端可以根据下行控制信息中携带的终端的IP地址，确定下行控制信息是否是发送给自己的，以便于该终端确定是否继续接收下行控制信息、下行应用层数据包，或者下行控制信息和下行应用层数据包。或者基站也可以在下行应用层数据包的MAC头中携带该终端的IP地址，该终端可以根据下行应用层数据包中携带的终端的IP地址，确定下行应用层数据包是否是发送给自己的，以便于终端确定是否需要丢弃该下行应用层数据包。
可选的，为了降低基站采用终端的IP地址对终端进行调度时带来的空口开销，当终端接入一个小区时，若该终端已经保存了网络侧设备为其分配的IP地址，则该终端可将其IP地址发送给基站，以便于基站采用该终端的IP地址或者IP地址中与其他终端不同的部分对该终端进行调度。
本发明实施例提供的数据传输方法中，处于空闲态的终端可以根据基站发送的下行控制信息中的数据传输指示接收基站发送的下行应用层数据包。具体的，处于空闲态的终端接收到基站发送的下行控制信息后，该终端根据下行控制信息中的数据传输指示确定基站指示该终端接收基站发送的下行应用层数据包，从而该终端可根据该数据传输指示，在下行控制信息指示的资源上接收基站发送的下行应用层数据包，即该终端和基站之间可以直接进行数据传输。
具体的，基站可以通过PDCCH向终端发送下行控制信息；从而终端也可以通过监听PDCCH接收基站发送的下行控制信息。
本发明实施例提供一种数据传输方法，该方法为处于空闲态的终端接收基站发送的下行控制信息，该下行控制信息中包含数据传输指示，该数据传输指示用于指示该终端接收基站发送的下行应用层数据包；且该终端根据该数据传输指示，接收基站发送的下行应用层数据包。基于上述技术方案，由于基站可以通过数据传输指示指示处于空闲态的终端接收基站发送的下行应用层数据包，因此该终端可以根据该数据传输指示直接接收基站发送的下行应用层数据包，从而发起数据传输。本发明实施例中，终端发起数据传输之后，终端与基站之间可以直接传输数据包，并不需要像现有技术中终端与基站之间传输数据包时会频繁地建立RRC连接和释放RRC连接，因此能够提高数据包的传输效率。
可选的，上述如图12所示的实施例中的下行控制信道可以是不同于现有技术的PDCCH的一条信道。例如通过另外一段资源发送上述下行控制信息(以下简称第一下行控制信息)，该另外一段资源即为上述的下行控制信道，且该第一下行控制信息所占的比特也较现有技术的下行控制信息所占的比特少(即该第一下行控制信息的内容较现有技术的下行控制信息的内容少)。例如，该第一下行控制信息只包括终端的标识和/或下行数据信道的无线资源信息。
可选的，上述如图12所示的实施例中，下行应用层数据包可以被替换为下行信令数据包、下行MAC层控制包或者下行物理层序 列。其中，对于下行应用层数据包、下行信令数据包、下行MAC层控制包以及下行物理层序列的描述及举例具体可以参见发明内容部分的相关描述(具体可参见发明内容部分位于第七方面之后，且位于第十三方面之前的一些可选方式中的相关描述)，此处不再赘述。
可选的，上述实施例中所述的终端的标识除了上述的C-RNTI，还可以是上述实施例一之前描述的终端在多个小区范围内共享的唯一的X-RNTI，该X-RNTI的长度比C-RNTI的长度长，比NAS的用户临时标识的长度短。例如，该X-RNTI的长度在16比特至40比特之间；优选的，该X-RNTI的长度为24比特。
本发明实施例的数据传输方法，由于处于空闲态的终端和基站之间可以传输多种数据包(例如应用层数据包、信令数据包、MAC层控制包和物理层序列)，因此能够使得终端更加方便、灵活地发起数据传输，从而使得终端和基站之间可以更加方便、灵活地直接传输数据包，提高数据包的传输效率。
