Description

一种资源分配的方法和基站 技术领域
本发明涉及无线技术领域，具体涉及一种资源分配的方法和基站。
背景技术
移动语音经历了从时分复用(Time Division Multiplexing，TDM)到互联网协议(Internet Protocol，IP)、从传统交换机到软交换的发展后，未来将走向移动宽带语音。在网络演进上，无线侧体现为从全球移动通信系统(Global System for Mobile Communications，GSM)/通用移动通信系统(Universal Mobile Telecommunications System，UMTS)等向长期演进(Long Term Evolution，LTE)系统发展，核心网侧体现为从电路交换(Circuit Switched，CS)向IP多媒体子系统(IP Multimedia Subsystem，IMS)发展。由于IMS支持多种接入和丰富的多媒体业务，成为全IP时代的核心网标准架构。基于IMS的LTE网络语音(Voice over Long Term Evolution，VoLTE)是无线和核心网技术发展的必然结果。
VoLTE的商用部署，业界已经达成共识，全球多地运营商相继推出VoLTE高清语音业务。预计到2014年底，全球VoLTE用户数将增长至5100万。VoLTE用户数的高速增长，用户对VoLTE语音质量的要求越来越高，相对LTE数据业务，对VoLTE的可靠性要求更高。
VoLTE业务可分为暂态、通话期和静默期。譬如，在通话期时，用户设备(User Equipment，UE)每20ms传送一次数据，在静默期时，UE间隔160ms发一个静默插入指示(Silence Insertion Descriptor，SID)帧。VoLTE这种间歇性小包业务特征，导致UE的VoLTE的上行业务依赖于UE向演 进基站(evolved NodeB，eNodeB)发送的调度请求(Scheduling Request，SR)。随着小区负载增大，VoLTE的UE发送SR的周期也会增加。
由于VoLTE是不可靠传输的业务，且eNodeB对承载SR的PUCCH信道解调不能做到完全可靠(存在一定的漏检错检概率)，当VoLTE业务丢包时，导致VoLTE语音质量下降，影响VoLTE的业务体验。
发明内容
本发明实施例提供了一种资源分配的方法和基站，用以提高VoLTE语音质量。
本发明实施例具体可以通过如下技术方案实现：
第一方面，本发明实施例提供了一种资源分配的方法，该方法包括：演进基站eNodeB获取用户设备UE的长期演进网络语音VoLTE的业务状态，所述业务状态包括通话期或静默期；所述eNodeB根据所述业务状态判断是否漏检所述UE发送的调度请求SR；若所述eNodeB漏检所述UE发送的所述SR，所述eNodeB向所述UE发送上行授权UL Grant。
第二方面，本发明实施例提供了一种基站，该基站包括：处理单元，用于获取用户设备UE的长期演进网络语音VoLTE的业务状态，所述业务状态包括通话期或静默期；所述处理单元，还用于根据所述业务状态判断是否漏检所述UE发送的调度请求SR；收发单元，用于若所述处理单元判断所述基站漏检所述UE发送的所述SR，向所述UE发送上行授权ULGrant。
第三方面，本发明实施例提供了一种基站，包括：处理器，用于获取用户设备UE的长期演进网络语音VoLTE的业务状态，所述业务状态包括通话期或静默期；所述处理器，还用于根据所述业务状态判断是否漏检所述UE发送的调度请求SR；收发器，用于若所述处理器判断所述基站漏检 所述UE发送的所述SR，向所述UE发送上行授权UL Grant。
本发明实施例通过获取UE的VoLTE的业务状态，eNodeB根据业务状态判断是否漏检UE发送的SR，当eNodeB确定漏检该UE发送的SR时，eNodeB向该UE发送上行授权UL Grant，以使该UE及时利用分配的上行资源进行数据传输，提高了VoLTE语音质量，确保VoLTE的业务体验。
附图说明
图1为本发明实施例提供的一种资源分配方法的流程图；
图2为本发明实施例提供的一种基站结构图；
图3为本发明实施例提供的另一种基站结构图。
具体实施方式
为使本发明的目的、技术方案、及优点更加清楚明白，下面结合附图并举实施例，对本发明提供的技术方案进一步详细描述。
在LTE系统中，通常来说，UE为进行上行数据传输，需要通过物理上行控制信道(Physical Uplink Control Channel，PUCCH)给eNodeB发送SR，eNodeB正确解调到UE的SR后，给UE分配资源，以使UE利用分配的资源发送上行数据。
当UE有上行数据发送时，向enodeB发送SR请求，如果eNodeB漏检或错检该SR，则eNodeB不会及时给UE分配上行资源，UE只能在下次SR周期到时，再向eNodeB发送SR，等待eNodeB正确解调到SR后，获取eNodeB分配给UE的上行资源后再发送上行数据。
由于VoLTE是不可靠传输的业务，如果SR漏检或错检的概率连续发生，就可能导致语音连续大量丢包，语音质量下降，影响VoLTE的业务体验。
例如，随着小区负载的增加，UE发送SR周期为40ms，如果eNodeB出现连续3个周期SR漏检或错检，UE的语音包丢包。当出现更大概率的连续漏检或错检时，丢包率升高，语音质量会明显下降。
在大话务场景，语音业务UE的SR周期会配置为80ms，这时即使SR不漏检或错检，语音包时延也会过大，影响语音质量，如果出现1次SR漏检，语音就会导致丢包，语音质量变差。
在LTE系统中，还存在预调度处理方法。预调度是指当eNodeB进行下行业务时，主动周期性的给UE分配上行资源，如UL grant，这样当UE有上行数据要发送时，就利用对应的资源进行发送，当UE没有上行业务时，则在分配的资源上填充padding。当eNodeB出现SR漏检或错检时，UE可以在稍后的预调度周期上发送语音包，不用等到下次SR周期，减少了语音包等待时延，降低丢包概率。但是预调度是周期生效的，eNodeB通过预调度周期性为UE分配上行资源，不区分VoLTE是通话期还是静默期，且不管UE是否有数据要发送。对于VoLTE业务来说，预调度存在增加上行资源块(Resource Block，RB)浪费，增加小区间的干扰以及增大UE耗电问题。
为方便描述，以SR漏检为例进行描述，在实施例中不对SR漏检和SR错检进行区分。
参见图1，本发明实施例提供的一种资源分配方法的流程图，包括：
步骤101、eNodeB获取UE的VoLTE的业务状态，该业务状态包括通话期或静默期。
eNodeB可以根据VoLTE业务包的长度获取该UE的VoLTE的业务状态。
步骤102、eNodeB根据获取的业务状态判断是否漏检该UE发送的SR。
eNodeB获取正确解调SR的时间间隔，若正确解调SR的时间间隔超过UE在上述业务状态时发送该SR的周期，则eNodeB确定漏检该UE发 送的SR；否则eNodeB确定未漏检该UE发送的SR。
步骤103、若eNodeB漏检该UE发送的该SR，则eNodeB向该UE发送UL Grant。
若eNodeB确定漏检该UE发送的SR，则eNodeB通过物理下行控制信道向该UE发送UL Grant，当UE获取该UL Grant后，利用获取的资源进行上行数据传输。
eNodeB可以根据VoLTE业务包的长度获取UE的VoLTE的业务状态。在通话期，VoLTE业务包的长度大于第一门限且小于第二门限，在静默期，VoLTE业务包的长度小于第一门限。
当VoLTE业务包的长度大于第一门限且小于第二门限时，eNodeB确定UE的VoLTE的业务状态为通话期；当VoLTE业务包的长度小于第一门限时，eNodeB确定UE的VoLTE的业务状态为静默期，其中，第一门限小于第二门限。
可选的，当eNodeB连续多次收到长度大于第一门限且小于第二门限的VoLTE业务包时，eNodeB确定UE的VoLTE的业务状态为通话期；当eNodeB连续多次收到长度小于第一门限的VoLTE业务包时，eNodeB确定UE的VoLTE的业务状态为静默期。
VoLTE业务的基于IP的语音传输(Voice over IP，VoIP)包的类型包括IPV4类型和IPV6类型。对于IPV4类型的VoIP包，第一门限可以为54byte，第二门限可以为220byte；对于IPV6类型的VoIP包，第一门限可以为74byte，第二门限可以为240byte。第一门限和第二门限的具体数值可按实际网络配置确定。
eNodeB获取UE的VoLTE的业务状态后，可以利用UE在该VoLTE业务状态向eNodeB发送SR的周期进行是否漏检该SR的判断。
若eNodeB获取UE的VoLTE的业务状态为通话期，由于在通话期，UE按第一周期向eNodeB发送SR，当eNodeB正确解调处于通话期的UE 所发SR的时间间隔超过该第一周期，则eNodeB确定漏检处于通话期的UE所发的SR。具体的，第一周期可以为5毫秒、10毫秒、20毫秒、40毫秒或80毫秒等。
若eNodeB获取UE的VoLTE的业务状态为静默期，由于在静默期，UE按第二周期向eNodeB发送SR，当eNodeB正确解调处于静默期的UE所发SR的时间间隔超过该第二周期，则eNodeB确定漏检处于静默期的UE所发的SR。具体的，第二周期可以为160毫秒，若eNodeB正确解调到SR时间间隔大于160毫秒，则eNodeB确定漏检SR。
eNodeB确定漏检SR后，可立刻将为UE分配的上行资源通过UL Grant发送给UE，以使UE获取上行资源后及时进行上行数据发送。
可选的，eNodeB确定漏检SR，且未调度该UE，则向UE发送UL Grant。
若未存在漏检，则eNodeB按正常流程处理，在本发明实施例中不再赘述。
eNodeB获取UE的VoLTE的业务状态，根据业务状态判断是否漏检UE发送的SR，当eNodeB确定漏检该UE发送的SR时，eNodeB向该UE发送上行授权UL Grant，以使该UE及时利用分配的上行资源进行数据传输，提高了VoLTE语音质量，确保VoLTE的业务体验；同时也能避免预调度资源存在的RB资源浪费，减轻了小区间的干扰，降低了UE的功耗。
参见图2，本发明实施例提供的一种基站结构图。eNodeB为LTE系统或LTE后续演进系统中的基站。基站20，用于执行图1的方法，包括：处理单元201和收发单元202。
处理单元201，用于获取UE的VoLTE的业务状态，该业务状态包括通话期或静默期；
该处理单元201，还用于根据该业务状态判断是否漏检UE发送的SR；
收发单元202，用于若该处理单元判断该基站漏检UE发送的SR，则 向该UE发送UL Grant。
处理单元201，可以根据VoLTE业务包的长度获取该UE的VoLTE的业务状态。当VoLTE业务包的长度大于第一门限且小于第二门限时，处理单元201确定UE的VoLTE的业务状态为通话期；当VoLTE业务包的长度小于第一门限时，处理单元201确定UE的VoLTE的业务状态为静默期，其中，第一门限小于第二门限。
可选的，当基站连续多次收到长度大于第一门限且小于第二门限的VoLTE业务包时，处理单元201确定UE的VoLTE的业务状态为通话期；当基站连续多次收到长度小于第一门限的VoLTE业务包时，处理单元201确定UE的VoLTE的业务状态为静默期。
对于IPV4，第一门限可以为54byte，第二门限可以为220byte；对于IPV6，第一门限可以为74byte，第二门限可以为240byte。
该处理单元201，还用于根据该业务状态判断是否漏检UE发送的SR，具体为：获取正确解调SR的时间间隔；若该时间间隔超过该UE在该业务状态时发送SR的周期，则处理单元201确定漏检该UE发送的SR。
若处理单元201获取UE的VoLTE的业务状态为通话期，由于在通话期，UE按第一周期向基站发送SR，当处理单元201正确解调处于通话期的UE所发SR的时间间隔超过该第一周期，则处理单元201确定漏检处于通话期的UE所发的SR。具体的，第一周期可以为5毫秒、10毫秒、20毫秒、40毫秒或80毫秒等。
若处理单元201获取UE的VoLTE的业务状态为静默期，由于在静默期，UE按第二周期向基站发送SR，当处理单元201正确解调处于静默期的UE所发SR的时间间隔超过该第二周期，则处理单元201确定漏检处于静默期的UE所发的SR。具体的，第二周期可以为160毫秒，若处理单元201正确解调到SR时间间隔大于160毫秒，则处理单元201确定漏检SR。
处理单元201确定漏检SR后，可立刻利用收发单元202将为UE分配 的上行资源通过UL Grant发送给UE，以使UE获取上行资源后及时进行上行数据发送。
可选的，处理单元201确定漏检SR，且未调度该UE，则通过收发单元202向UE发送UL Grant。
需要说明的是，本发明实施例中的处理单元201可以为基站处理器，也可以集成在基站的某一个处理器中实现，此外，也可以以程序代码的形式存储于基站的存储器中，由基站的某一个处理器调用并执行以上处理单元201的功能。收发单元202可以分别与基站的发送器和接收器对应，也可以对应基站的收发器。这里所述的处理器可以是一个中央处理器(Central Processing Unit，CPU)，或者是特定集成电路(Application Specific Integrated Circuit，ASIC)，或者完成实施本发明实施例的一个或多个集成电路。参见图3，本发明实施例提供的另一种基站结构图，基站30，包括处理器301和收发器302。
基站获取UE的VoLTE的业务状态，根据业务状态判断是否漏检UE发送的SR，当基站确定漏检该UE发送的SR时，向该UE发送上行授权UL Grant，以使该UE及时利用分配的上行资源进行数据传输，提高了VoLTE语音质量，确保VoLTE的业务体验；同时也能避免预调度资源存在的RB资源浪费，减轻了小区间的干扰，降低了UE的功耗。
应注意，上述例子是为了帮助本领域技术人员更好地理解本发明实施例，而非要限制本发明实施例的范围。本领域技术人员根据所给出的上述的例子，显然可以进行各种等价的修改或变化，这样的修改或变化也落入本发明实施例的范围内。

所属领域的技术人员可以清楚地了解到，为了描述的方便和简洁，上述描述的系统、装置和单元的具体工作过程，可以参考前述方法实施例中的对应过程，在此不再赘述。
在本申请所提供的几个实施例中，应该理解到，所揭露的系统、装置和方法，可以通过其它的方式实现。例如，以上所描述的装置实施例仅仅是示意性的，例如，单元的划分，仅仅为一种逻辑功能划分，实际实现时可以有另外的划分方式，例如多个单元或组件可以结合或者可以集成到另一个系统，或一些特征可以忽略，或不执行。另外，所显示或讨论的相互之间的耦合或直接耦合或通信连接可以是通过一些接口、装置或单元的间接耦合或通信连接，也可以是电的，机械的或其它的形式连接。
作为分离部件说明的单元可以是或者也可以不是物理上分开的，作为单元显示的部件可以是或者也可以不是物理单元，即可以位于一个地方，或者也可以分布到多个网络单元上。可以根据实际的需要选择其中的部分或者全部单元来实现本发明实施例方案的目的。
另外，在本发明各个实施例中的各功能单元可以集成在一个处理单元中，也可以是各个单元单独物理存在，也可以是两个或两个以上单元集成在一个单元中。上述集成的单元既可以采用硬件的形式实现，也可以采用软件功能单元的形式实现。
通过以上的实施方式的描述，所属领域的技术人员可以清楚地了解到本发明可以用硬件实现，或固件实现，或它们的组合方式来实现。当使用软件实现时，可以将上述功能存储在计算机可读介质中或作为计算机可读介质上的一个或多个指令或代码进行传输。计算机可读介质包括计算机存储介质和通信介质，其中通信介质包括便于从一个地方向另一个地方传送 计算机程序的任何介质。存储介质可以是计算机能够存取的任何可用介质。以此为例但不限于：计算机可读介质或其他光盘存储、磁盘存储介质或者其他磁存储设备、或者能够用于携带或存储具有指令或数据结构形式的期望的程序代码并能够由计算机存取的任何其他介质。
总之，以上仅为本发明技术方案的较佳实施例而已，并非用于限定本发明的保护范围。凡在本发明的原则之内，所作的任何修改、等同替换、改进等，均应包含在本发明的保护范围之内。
