相关申请的交叉引用
本申请基于申请号为201610332856.8、申请日为2016年05月18日的中国专利申请提出，并要求该中国专利申请的优先权，该中国专利申请的全部内容在此引入本申请作为参考。
技术领域

背景技术
承载在长期演进网络的语音(VoLTE)业务是基于IP多媒体子系统(IMS，IP Multimedia Subsystem)的语音业务。对于VoLTE业务来说，在无线信号质量较弱的区域，起呼时会出现会话初始协议(SIP，Session Initiation Protocol)消息发送失败或丢失的现象。由于SIP消息大小为无线资源控制(RRC，Radio Resource Control)消息大小的上百倍，虽然目前在无线侧进行了适当优化，但优化后仍然无法满足深度覆盖的要求。尤其是当UE处于弱覆盖区域，且UE根据SIP消息实际大小向演进型基站(eNB，evolved Node B)索要资源时，这种情况下UE上行需要传输的数据包会超过本身的传输能力，从而会导致丢包和频繁重传，进而影响VoLTE呼叫性能。

具体实施方式
下面结合附图及实施例对本发明再作进一步详细的描述。
正如背景技术所描述的，SIP消息大小为RRC消息大小的上百倍(例 如SIP邀请(Invite)消息为2000Bytes，而RRC连接建立(RRCConnectionSetup)消息仅为30Bytes)，虽然在无线侧进行了适当优化(在无线链路控制(RLC，Radio Link Control)层对数据进行切割分段4次，使得每个分段的数据大小都能够承载在基站分配的资源上)，但是这种优化仍然无法满足深度覆盖的要求。这种不满足主要体现在链路预算上，由于终端的最低参考信号接收功率(RSRP，Reference Signal Receiving Power)仅能达到约-118dBm，因此在弱覆盖区域，当UE根据SIP消息实际大小向eNB索要资源时，UE上行需要传输的数据包就会超过自身的传输能力，从而造成SIP包多次重传甚至丢包，进而会导致VoLTE呼叫时延过长或呼叫失败问题，影响VoLTE呼叫性能。
同时，考虑到SIP信令是纯文本格式，压缩效率会很高，压缩效果更明显，所以UE可以通过上报自身的压缩能力，并在数据包发送前先对其进行压缩处理的方式，来减少空口传输数据包的大小。
基于此，在本发明的各种实施例中：UE向基站上报自身的能力参数；上报的能力参数能够指示所述UE具备数据压缩能力；基于自身具备的压缩能力，对待发送数据进行压缩；以及将压缩后的数据发送至所述基站；而所述基站接收到所述UE发送的数据后根据所述UE上报的能力，判断所述UE是否具备数据压缩能力；当判断结果表征所述UE具备数据压缩能力时，对接收的数据进行解压缩；以及将解压缩后的数据发送至核心网。
实施例一
本实施例提供一种上行数据传输方法，应用于UE，如图1所示，该方法包括以下步骤：
步骤101：所述UE向基站上报自身的能力参数；
这里，上报的能力参数能够指示所述UE具备数据压缩能力。
实际应用时，执行步骤101的时机可以是：所述UE最初附着时，还可 以是所述UE进行随机接入时，也可以是所述UE周期性上报自身的能力参数。
实际应用时，本步骤的具体实现可以包括：
所述UE在UE能力(UE Capability)参数中增加第一变量(新变量，可以命名为数据压缩索引(DataCompressionIndex))，即所述UE Capability参数中包括第一变量，所述第一变量指示所述UE支持数据压缩能力；向所述基站发送所述UE Capability参数。
其中，这种实现方式中，所述UE仅通知了所述基站自身具备数据压缩能力，而没有通知所述基站自身支持的压缩算法。
基于此，在一实施例中，本步骤的具体实现还可以是：
向所述基站上报自身支持的至少一种压缩算法。
这里，实际应用时，可以向所述基站上报具体的某种压缩算法，还可以向所述基站上报自身支持的压缩算法集合。
步骤102：所述UE基于自身具备的压缩能力，对待发送数据进行压缩；
具体地，采用自身支持的压缩算法对所述待发送数据进行压缩。
更具体地，采用自身支持的至少一种压缩算法中的一种压缩算法对所述待发送数据进行压缩。
其中，当所述UE仅向所述基站上报具体的某种压缩算法时，采用上报的某种压缩算法对所述待发送数据进行压缩。
当所述UE向所述基站上报了自身支持的压缩算法集合时，可以采用压缩算法集合中的任意一种压缩算法对所述待发送数据进行压缩。
在一实施例中，所述对待发送数据进行压缩之前，该方法还可以包括：
接收所述基站发送的第一信令消息；
解析所述第一信令消息，得到第一指示；
采用第一指示所指示的压缩算法，对所述待发送数据进行压缩。
其中，所述第一指示所指示的压缩算法为所述UE自身所支持的压缩算法。

在一实施例中，所述对待发送数据进行压缩之前，该方法还可以包括：
接收所述基站发送的第二信令消息；
解析所述第二信令消息，得到第二指示；
根据所述第二指示判断是否需要开启数据压缩功能；
当判断结果表征需要开启数据压缩功能时，开启数据压缩功能；
相应地，开启数据压缩功能后对待发送数据进行压缩。
其中，所述第二信令消息可以是RRC消息等。
实际应用时，还可以进一步通过第二信令消息指示所述UE所使用的压缩算法。
基于此，该方法还可以包括：
进一步解析所述第二信令消息，得到第三指示；
相应地，采用所述第三指示所指示的压缩算法，对所述待发送数据进行压缩。
这里，所述第三指示所指示的压缩算法为所述UE自身所支持的压缩算法。
实际应用时，进行压缩的待发送数据可以是物理层、网络层、传输层或应用层等协议层的数据。
其中，根据需要确定对哪个协议层的数据进行压缩。可以根据各协议层标识或者各协议层数据速率的变化来看出是对哪个协议层的数据进行了压缩。
步骤103：所述UE将压缩后的数据发送至所述基站。
本实施例还提供了一种上行数据传输方法，应用于基站，如图2所示， 该方法包括以下步骤：
步骤201：所述基站接收UE上报的能力参数；
步骤202：所述基站接收所述UE发送的数据；
步骤203：所述基站根据所述UE上报的能力参数，判断所述UE是否具备数据压缩能力；
这里，实际应用时，也可以先执行步骤203再执行步骤202，即所述基站收到UE上报的能力参数后，先根据所述UE上报的能力参数，判断所述UE是否具备数据压缩能力，得到判断结果后，再接收所述UE发送的数据，然后根据判断结果来决定是否对接收的数据进行解压缩，当判断结果表征所述UE具备数据压缩能力时，所述基站对接收的数据进行解压缩，即执行步骤204。
实际应用时，所述UE可以在UE Capability参数中增加第一变量(新变量，可以命名为DataCompressionIndex)，所述第一变量指示所述UE支持数据压缩能力。在这种情况下，本步骤的具体实现包括：
对UE Capability参数进行解析，根据解析结果判断所述UE Capability参数中是否携带有第一变量；当判断结果表征所述UE Capability参数中存在第一变量时，根据所述第一变量，判断所述UE是否具备数据压缩能力。
其中，可以根据所述第一变量的赋值，来判断所述UE是否具备数据压缩能力。举个例子来说，当所述第一变量为0时，表示所述UE不具备数据压缩能力；当所述第一变量为1时，表示所述UE具备数据压缩能力。
这种实现方式中，所述基站仅获知了所述UE具备数据压缩能力，而没有获知所述UE自身支持的压缩算法。
基于此，在一实施例中，本步骤的具体实现还可以是：
对上报的能力参数进行解析，根据解析结果判断上报的能力参数中是否携带有所述UE支持的至少一种压缩算法。
其中，当上报的能力参数中未携带有所述UE支持的至少一种压缩算法时，表明所述UE不具备数据压缩能力；当上报的能力参数中携带有所述UE支持的至少一种压缩算法，表示所述UE具备数据压缩能力。
实际应用时，所述UE可以向所述基站上报具体的某种压缩算法，还可以向所述基站上报自身支持的压缩算法集合，从而使得所述基站通过解析上报的能力参数，可以得到某种压缩算法或者所述UE所支持的压缩算法集合。

所述基站向所述UE发送所述第二信令消息。
其中，可以设定无线环境质量(信号强度)的阈值和负载阈值；根据设定的阈值来判断所述UE是否需要开启数据压缩功能。举个例子来说，当信号强度低于阈值和/或负载超过阈值时，则认为所述UE需要开启数据压缩功能；当信号强度高于阈值且负载小于阈值时，认为所述UE不需要开启 数据压缩功能。

步骤204：当判断结果表征所述UE具备数据压缩能力时，所述基站对接收的数据进行解压缩；
具体地，当所述UE通知了所述基站自身具备数据压缩能力，而没有通知所述基站自身支持的压缩算法时，所述基站可以按照预先设定的压缩算法对接收的数据进行解压缩；或者，当所述UE仅向所述基站上报具体的某种压缩算法时，所述基站可以按照预先设定的压缩算法对接收的数据进行解压缩，但这种预先设定的压缩算法应该是所述UE通知的压缩算法。
当所述UE未通知所述基站自身支持的压缩算法，或者仅通知了所述基站自身支持的压缩算法集合时，所述基站可以采用设定的压缩算法集合，利用盲检的方式对接收的数据进行解压缩。
其中，所述盲检的方式是指：所述基站利用设定的压缩算法集合中的每个压缩算方法去尝试对接收的数据进行解压缩，直至对接收的数据正确解压缩为止。
当所述基站为所述UE确定了压缩算法，且指示给了所述UE时，所述基站采用确定的压缩算法对接收的数据进行解压缩。
当判断结果表征所述UE不具备数据压缩能力时，所述基站不对接收的数据进行解压缩，直接将接收的数据发送给核心网。
实际应用时，进行压缩的数据可以是物理层、网络层、传输层或应用层等协议层的数据。相应地，所述基站进行解压缩的数据可以是物理层、网络层、传输层或应用层等协议层的数据。实际应用时，可以根据各协议层标识或者各协议层数据速率的变化来看出是对哪个协议层的数据进行了压缩。
步骤205：所述基站将解压缩后的数据发送至核心网。

这里，实际应用时，也可以先执行步骤303再执行步骤302，即所述基站收到UE上报的能力参数后，先根据所述UE上报的能力参数，判断所述UE是否具备数据压缩能力，得到判断结果后，再接收所述UE发送的数据，然后根据判断结果来决定是否对接收的数据进行解压缩，当判断结果表征所述UE具备数据压缩能力时，所述基站对接收的数据进行解压缩，即执行步骤304。
步骤304：当判断结果表征所述UE具备数据压缩能力时，所述基站对接收的数据进行解压缩；
步骤305：所述基站将解压缩后的数据发送至核心网。
这里，需要说明的是：所述UE与基站的具体处理过程已在上文详述，这里不再赘述。
从上面的描述中可以看出，本发明实施例提供的方案，如图4所示，主要包括：首先，UE向eNB上报自身的能力参数，以指示是否支持数据压缩功能(步骤401)；其次，基站根据UE上报的能力参数，检测UE是否支持数据压缩功能(步骤402)；当检测到UE支持数据压缩功能时，基站收到UE发送的数据包后，对UE发送的数据包进行解压缩，之后再转发给核心网(步骤403)；当检测到UE不支持数据压缩功能时，基站收到UE发送的数据包后，不对UE发送的数据包进行解压缩，直接转发给核心网(步骤404)。
本发明实施例提供的上行数据传输方法，UE向基站上报自身的能力参数；上报的能力参数能够指示所述UE具备数据压缩能力；所述UE基于自身具备的压缩能力，对待发送数据进行压缩；并将压缩后的数据发送至所述基站；所述基站接收所述UE发送的数据；所述基站根据所述UE上报的能力参数，判断所述UE是否具备数据压缩能力；当判断结果表征所述UE具备数据压缩能力时，所述基站对接收的数据进行解压缩，由于在数据发送前UE对数据包进行了压缩处理，如此，能有效地减少空口传输数据包的大小，从而有效地提升了上行覆盖，即提高了小区边缘覆盖范围，这样就能保证UE在弱覆盖区域的起呼成功率，从而满足用户语音及数据业务的使用需求，提升用户体验。

如果eNB检测到此时无线环境质量较好或负载较轻，则指示UE不用开启数据压缩功能，UE收到指示后，不对网络层的数据包进行压缩，直接发送给eNB；相应地，eNB收到UE发送的数据包后，直接将数据包转发给核心网。
如果eNB检测到此时无线环境质量较差或负载较重，则指示UE开启数据压缩功能，且指示UE采用压缩算法C进行数据压缩；UE收到指示后开启数据压缩功能，并采用压缩算法C对网络层的数据包进行压缩，并在压缩后发送给eNB；eNB收到UE发送的数据包后，使用压缩算法C对UE网络层的数据包进行解压缩，然后转发至核心网。
