Description

一种资源分配和传输数据包的方法及设备 技术领域
本申请涉及无线通信技术领域，特别涉及一种资源分配和传输数据包的方法及设备。
背景技术
为方便人们的生活，在现有的通信系统中引入了eMTC(Enhanced Machine Type，增强机器类型通信)业务，通过eMTC业务可以将物与物连接起来。例如居民日常用的水表，水表与通信终端连接起来后，可以用户可以实时了解用水量的情况。
由于基站在调度eMTC业务的数据包和非eMTC业务的数据包时共享小区时频资源，当基站采用半静态调度的机制调度非eMTC业务的数据包时，导致基站将eMTC业务的数据包和非eMTC业务的数据包调度到相同的时频资源上，造成eMTC业务的数据包和非eMTC业务的数据包在传输时的冲突。
现有技术中，基站在检测到将eMTC业务的数据包和非eMTC业务的数据包调度到相同的时频资源上时，为保证通信的正常进行，基站将eMTC业务的数据包和非eMTC业务的数据包中的一个数据包调度到该时频资源上，另一个业务的数据包不再调度、直接丢弃，这种技术方案对另一个业务的性能有较大损失，降低了用户体验。
发明内容
有鉴于此，本申请实施例提供了一种资源分配和传输数据包的方法及设备，以期解决现有技术中在传输资源发生冲突时，对其中一个业务性能造成较大损失，导致降低用户体验的问题。
第一方面，本申请提供一种资源分配的方法，包括：
基站向第一终端发送第一指示信息，其中，第一指示信息用于指示为周 期性传输第一终端的业务数据包所分配的第一资源；
基站在当前周期第一资源发生传输资源冲突时，为第一终端分配第二资源，具体的，第二资源与第一资源为不同的传输资源；
应理解，当前周期第一资源发生传输资源冲突，指的是，基站在当前周期为传输第二终端的业务数据包所分配的传输资源中包括第一资源。
基站向第一终端发送第二指示信息，其中，第二指示信息用于指示在当前周期内为传输第一终端的业务数据包所分配的第二资源。
由于基站在第一资源发生资源冲突时，将第一终端传输的业务数据包调度到第二资源上，因此，与现有技术中丢弃其中一个数据包相比，提高了业务的性能，从而提高了用户体验。
第一终端的业务数据包和第二终端的业务数据包的传输可以是上行传输，也可以是下行传输。即，第一终端的业务数据包和第二终端的业务数据包可以由终端发送给基站，也可以由基站发送给终端。
在第一方面的基础上，可选的，第一终端的业务数据包为非eMTC业务数据包，第二终端的业务数据包为eMTC业务数据包。
在第一方面的基础上，可选的，基站向第一终端发送第三指示信息，其中，第三指示信息用于指示停止采用第一资源周期性传输第一终端的业务数据包。
第二方面，本申请提供了一种传输数据包的方法，包括：
终端接收基站发送的第一指示信息，第一指示信息用于指示基站为周期性传输该终端的业务数据包所分配的第一资源；
终端启动在第一资源上周期性发送或接收业务数据包；
终端接收到基站发来的第二指示信息，第二指示信息用于指示基站在当前周期内为传输该终端的业务数据包所分配的第二资源，其中，第二资源与第一资源为不同的传输资源；
终端在当前周期采用第二资源发送或接收业务数据包。
由于终端基于指示信息确定在哪个传输资源上传输业务数据包，从而使 得终端在接收到第二指示信息后能够在第二资源上传输业务数据包，降低了在第一资源在发生资源冲突时丢弃该业务数据包的可能性，因而提高了用户体验。
终端的业务数据包的传输可以是上行传输，也可以是下行传输。即，终端的业务数据包可以由终端发送给基站，也可以由基站发送给终端。
在第二方面的基础上，可选的，终端在下一周期采用第一资源发送或接收业务数据包。
具体的，终端在下一周期采用第一资源向基站发送业务数据包，或者，终端在下一周期采用第一资源接收基站发送的业务数据包。
由于终端在当前周期接收到第二指示信息后，不再在第一资源上传输业务数据包，而在下一周期继续采用第一资源传输业务数据包，从而避免了动态为第一终端分配传输资源导致的增加PDCCH的开销，提高了基站的性能。
在第二方面的基础上，可选的，终端接收基站发送的第三指示信息，第三指示信息用于指示停止采用第一资源周期性传输该终端的业务数据包，终端根据第三指示信息停止在第一资源上周期性发送或接收业务数据包。
在第二方面的基础上，可选的，当前周期内基站分配给其它终端的资源包括所述第一资源时，终端接收基站发送的第二指示信息。
在第二方面的基础上，可选的，终端的业务数据包为非eMTC业务数据包，其它终端的业务数据包为eMTC业务数据包。

具体实施方式
为了使本申请的目的、技术方案和优点更加清楚，下面将结合附图对本申请作进一步地详细描述。
下面首先对本申请中的部分用语进行解释说明，以便于本领域技术人员理解。
1)、终端，又称之为UE(User Equipment，用户设备)，是一种向用户提供语音和/或数据连通性的设备，例如，具有无线连接功能的手持式设备、车载设备等。常见的终端包括：手机、平板电脑、笔记本电脑、掌上电脑、MID(Mobile Internet Device，移动互联网设备)、可穿戴设备(如智能手表、智能手环、计步器)等。
2)、基站，又称为RAN(Radio Access Network，无线接入网)设备，是一种将终端接入到无线网络的设备，包括但不限于：eNB(evolved Node B，演进型节点B)、RNC(radio network controller，无线网络控制器)、NB(Node B，节点B)、BSC(Base Station Controller，基站控制器)、BTS(Base Transceiver Station，基站收发台)、家庭基站(如Home evolved NodeB、Home Node B)、BBU(Base Band Unit，基带单元)，此外，本申请中基站还可以为WiFi(Wireless Fidelity，无线保真)AP(Access Point，接入点)等。
3)、“多个”是指两个或两个以上。“和/或”，描述关联对象的关联关系，表示可以存在三种关系，例如，A和/或B，可以表示：单独存在A，同时存在A和B，单独存在B这三种情况。字符“/”一般表示前后关联对象是一种“或”的关系。
请参考图1，其为本申请实施例提供的一种通信系统的示意图，该通信系统包括基站100、终端110、终端120、终端130等，下面以图1所示的系统架构 为例对本申请的实施例进行详细介绍。
由于现有技术中，为了降低控制信息的开销，增加通信系统的吞吐量，通常采用半静态调度的方式为语音业务数据包分配时频资源，具体的，以图1中的终端110为例，基站100在激活半静态调度后，在PDCCH(Physical Downlink Control Channel，物理下行控制信道)向终端110发送指示信息，指示终端110在哪些时频资源上传输，以下行通信为例进行说明，如图2a所示，基站100通过PDCCH向终端110发送指示信息后，当基站100需要向终端110发送语音业务数据包时，则无需再在PDCCH上发送指示信息，直接通过PDSCH(Physical Downlink Shared Channel，物理下行共享信道)向终端110发送语音业务数据包即可，具体的，如图2b所示，每隔20ms通过相同位置的时频资源向终端110发送语音业务数据包，其中，还可以每隔40ms通过相同位置的时频资源向终端110发送语音业务数据包，在PDCCH向终端110发送去激活的指示信息后，停止半静态调度。
需要说明的是，这里的半静态调度周期，例如20ms，40ms，仅仅用于举例，并非用于限制本申请。
在现有通信系统中引入eMTC业务后，其中基站100调度eMTC业务数据包的方式为基站100首次在调度eMTC业务数据包后，占用一段时频资源重复发送该数据包，如图2c所示，填充区域的时频资源为基站为eMTC业务数据包分配的时频资源。
然而由于eMTC业务和语音业务共享小区的时频资源，当基站100为终端110的语音业务分配的时频资源为如图2b所示的填充区域的时频资源、且基站100为终端120的eMTC业务分配的时频资源为如图2c所示的填充区域的时频资源时，基站100由于在将第三个20ms用于传输语音业务数据包的时频资源还分配给了eMTC业务数据包，造成时频资源发生冲突。
由于现有技术中基站100在发生时频资源冲突时，不再在发生冲突的时频资源上调度其中一个数据包，因此会导致不调度数据包所在业务的性能的损失，降低用户的体验。
为解决上述问题，如图3所示，本申请提供了一种资源分配的方法，包括：
步骤300，基站100向终端110发送第一指示信息，第一指示信息用于指示为周期性传输终端110的业务数据包所分配的第一资源。
该步骤300中，当周期性传输终端110的业务数据包为语音业务数据包或其它半静态调度的业务数据包时，该第一指示信息用于激活终端110的半静态调度。例如，基站100可以通过PDCCH下发第一指示信息，该第一指示信息可以为DCI(downlink control information，下行控制信息)，指示了为终端分配的半静态调度的资源，即终端进行周期性发送或接收的资源。具体的，终端110可通过第一资源向基站发送业务数据包，也可以通过第一资源接收基站发送的业务数据包。
此外，在以上步骤300之前，基站100可以向终端110下发半静态调度的配置信息，终端110通过该配置信息可以获取半静态调度的周期。终端110在收到该半静态调度的配置信息之后，终端检测到PDCCH上的第一指示信息，便可以激活该半静态调度，进行数据发送或接收。半静态调度的配置信息可以为RRC(radio resource control，无线资源控制)配置信息。
需要说明的是，在本申请实施例中第一终端传输的业务数据包可以为语音业务数据包，如VoIP(Voice over Internet Protocol，基于因特网协议的语音)业务数据包，还可以为其他周期性传输的业务数据包，基站能够基于事先为这些周期性传输的数据包分配资源的策略或算法就能够直接为这些业务数据包分配资源，而无需动态分配资源。可选的，第一终端传输的业务数据包为非eMTC业务数据包。
步骤301，基站100在当前周期为传输终端120的业务数据包所分配的传输资源中包括第一资源时，为终端110分配第二资源，第二资源与第一资源为不同的传输资源。
例如，如图2b所示，假设线条a和线条b之间填充资源块基站在分配给终端110传输业务数据包的同时，分配给终端120传输业务数据包，造成线条a和线条b之间填充资源块发生资源冲突，基站100重新为终端110分配第 二资源，其中第二资源可以为线条a和线条b之间除填充资源块以外其它处于空闲状态的资源块，也可以为下一时刻处于空闲状态的资源块。本申请不以此为限，只要不与当前周期内的第一资源冲突即可。
可选的，终端120传输的业务数据包为eMTC业务数据包。
步骤302，基站100向终端110发送第二指示信息，第二指示信息用于指示在当前周期内为传输终端110的业务数据包所分配的第二资源。
在本申请中，终端110和终端120为不同的终端，终端110和终端120分别的数据包的业务可以为不同的业务，也可以为相同的业务。
如图4所示，以第一终端传输的业务数据包为语音业务数据包，第二终端传输的业务数据包为eMTC业务数据包为例对传输数据包的方法进行详细说明，在第一终端与第二终端发生传输资源冲突时，当第一终端和第二终端传输的数据包分别为其它业务的数据包时，与第一终端传输的业务数据包为语音业务数据包、第二终端传输的业务数据包为eMTC业务数据包在发生传输资源冲突时传输数据包的方法类似，在此不再赘述。
如图4所示，本申请实施例一种传输数据包的方法，包括：
步骤400，基站向第一终端发送RRC信令，RRC信令中包括半静态调度配置信息，半静态调度配置信息中包括半静态调度的周期等信息；第一终端接收RRC信令，获取半静态调度配置信息。
步骤410，基站向第一终端发送第一指示信息，第一指示信息用于指示为周期性传输第一终端的业务数据包所分配的第一资源；第一终端接收第一指示信息。
通过步骤400和步骤410实现了基站与第一终端之间业务数据包的半静态调度的配置和激活，如此第一终端便可以利用半静态资源，即第一资源，进行周期性的传输。同样基站也可以利用该半静态资源，向第一终端发送业务数据包。
步骤420，第一终端通过第一资源与基站之间周期性传输业务数据包。
以第一终端的业务数据包为语音业务数据包为例，在当前半静态调度周 期内，基站在收到第一终端的语音业务数据包时，基站通过第一资源向第一终端发送语音业务数据包；当第一终端需要向基站发送语音业务数据包时，第一终端通过第一资源向基站发送语音业务数据包。
步骤430，基站有第二终端的业务数据包需要发送或者接收到第二终端传输业务数据包的请求时，为第二终端分配资源，并向第二终端发送资源配置信息，资源配置信息用于指示为传输第二终端的业务数据包所分配的传输资源，第二终端接收资源配置信息，确定在资源配置信息指示的传输资源上传输或接收业务数据包。
需要说明的是，当第二终端的业务数据包为eMTC业务数据包时，基站基于预先配置的策略会为第二终端分配连续的传输资源。
步骤440，第二终端在资源配置信息指示的传输资源上传输或接收业务数据包。
步骤450，基站在当前半静态调度周期检测到为第二终端分配的资源中包括第一资源时，为第一终端分配第二资源，并向第一终端发送第二指示信息，第二指示信息用于指示在当前半静态调度周期内为传输第一终端的业务数据包所分配的第二资源，其中，第二资源与第一资源为不同的传输资源。
步骤460，第一终端接收第二指示信息后，在当前半静态调度周期采用第二资源传输或接收业务数据包。
步骤470，第一终端在下一个半静态调度周期继续采用第一资源传输或接收业务数据包。
具体的，当在下一个周期有第一终端的业务数据包需要继续传输时，若基站在下一个周期在检测到第一资源未发生资源冲突、且未向第一终端发送去激活半静态调度的指示信息，则在下一个周期继续采用第一资源传输业务数据包。
当在下一个周期有第一终端的业务数据包需要继续传输时，若基站在下一个周期在检测到第一资源发生资源冲突，则基站再次重新为第一终端动态分配新的传输资源，该传输资源与第一传输资源为不同的传输资源，然后向 第一终端发送指示传输业务数据包所采用的传输资源的信息，第一终端在下个半静态调度周期采用基站重新分配的新的传输资源传输或接收业务数据包。
此外，基站向第一终端发送第三指示信息，第三指示信息用于指示停止采用第一资源周期性传输第一终端的业务数据包，即停止半静态调度。以语音业务数据包为例，第三指示信息为去激活半静态调度的指示信息，当基站检测到满足去激活半静态调度的条件后，向第一终端发送去激活半静态调度的指示信息。具体的，基站向第一终端发送第三指示信息在基站向第一终端发送第一指示信息之后，可以在为第一终端分配第二资源之前，也可以在为第一终端分配第二资源之后。
当在下一个周期有第一终端的业务数据包需要继续传输时，若基站已经向第一终端发送了去激活半静态调度的指示信息，则基站激活半静态调度，也可以通过动态调度为第一终端分配传输资源。
需要说明的是，在图4所示的传输数据包的方法中，步骤400～步骤420与步骤430、步骤440之间没有必然的先后顺序，只要步骤400、步骤410、步骤420顺序不变、步骤430、步骤440之间的顺序不变即可。
需要说明的是，以上实施例中，第一终端的业务数据包和第二终端的业务数据包的传输可以是上行传输，也可以是下行传输。即，第一终端的业务数据包和第二终端的业务数据包可以由终端发送给基站，也可以由基站发送给终端。
由于在本申请中基站在第一资源发生资源冲突时，将第一终端传输的业务数据包调度到第二资源上，因此，与现有技术中丢弃其中一个数据包相比，提高了业务的性能，从而提高了用户体验。
基于同一发明构思，本申请实施例中还提供了一种具有本申请实施例资源分配功能的基站，由于本申请实施例中的基站对应的方法为本申请实施例资源分配的方法，因此本发明实施例基站的实施可以参见该方法的实施例，重复之处不再赘述。

需要说明的是，第一终端的业务数据包和第二终端的业务数据包的传输可以是上行传输，也可以是下行传输。即，第一终端的业务数据包和第二终端的业务数据包可以由终端发送给基站，也可以由基站发送给终端。
可选的，第一终端的业务数据包为eMTC业务数据包，第二终端的业务数据包为eMTC业务数据包。

这里的处理元件同以上描述，可以是通用处理器，例如中央处理器(Central Processing Unit，CPU)，还可以是被配置成实施以上方法的一个或多个集成电路，例如：一个或多个特定ASIC，或，一个或多个DSP，或，一个或者多个FPGA等。存储元件可以是一个存储器，也可以是多个存储元件的统称。
基于同一发明构思，本申请实施例中还提供了一种具有本申请实施例传输数据包功能的终端，由于本申请实施例中的终端对应的方法为本申请实施例传输数据包的方法，因此本发明实施例终端的实施可以参见该方法的实施例，重复之处不再赘述。
如图7所示，本申请实施例一种终端700，包括：收发单元710和处理单元720，其中，收发单元710用于接收第一指示信息，第一指示信息用于指示为周期性传输终端700的业务数据包的第一资源；处理单元720用于根据收发单元710接收的第一指示信息，启动在第一资源上周期性传输或接收业务数据包；收发单元710还用于接收第二指示信息，第二指示信息用于指示在当前周期内为传输终端700的业务数据包所分配的第二资源，第二资源与第一资源为不同的传输资源；处理单元720还用于控制收发单元710在当前周期采用第二资源发送或接收业务数据包。
需要说明的是，第一终端的业务数据包和第二终端的业务数据包的传输 可以是上行传输，也可以是下行传输。即，第一终端的业务数据包和第二终端的业务数据包可以由终端发送给基站，也可以由基站发送给终端。
可选的，处理单元720还用于控制收发单元710在下一周期采用第一资源发送或接收业务数据包。
可选的，收发单元710还用于接收第三指示信息，第三指示信息用于指示停止采用第一资源周期性传输终端700的业务数据包；处理单元720根据第三指示信息，停止在第一资源上周期性发送或接收业务数据包。
可选的，收发单元710在当前周期内基站分配给其它终端的资源包括第一资源时，接收第二指示信息。
可选的，终端的业务数据包为非增强机器类型通信eMTC业务数据包，其它终端的业务数据包为eMTC业务数据包。
应理解，终端700中的各个单元的划分仅仅是一种逻辑功能的划分，实际实现时可以全部或部分集成到一个物理实体上，也可以物理上分开。且这些单元可以全部以软件通过处理元件调用的形式实现；也可以全部以硬件的形式实现；还可以部分单元通过软件通过处理元件调用的形式实现，部分单元通过硬件的形式实现。例如，处理单元720可以为单独设立的处理元件，也可以集成在终端的某一个芯片中实现，此外，也可以以程序的形式存储于终端的存储器中，由终端中的某一个处理元件调用并执行以上各个单元的功能。其它单元的实现与之类似。此外这些单元全部或部分可以集成在一起，也可以独立实现。这里所述的处理元件可以是一种集成电路，具有信号的处理能力。在实现过程中，上述方法的各步骤或以上各个单元可以通过处理器元件中的硬件的集成逻辑电路或者软件形式的指令完成。
例如，以上这些单元可以是被配置成实施以上方法的一个或多个集成电路，例如：一个或多个特定ASIC，或，一个或多个DSP，或，一个或者多个FPGA等。再如，当以上某个单元通过处理元件调度程序的形式实现时，该处理元件可以是通用处理器，例如CPU或其它可以调用程序的处理器。再如，这些单元可以集成在一起，以SOC的形式实现。
请参见图8，图8为本发明实施例提供的一种终端的硬件结构示意图。如图8所示，该终端包括：处理器810、存储器820、收发装置830。收发装置830可以与天线连接。在下行方向上，收发装置830通过天线接收基站发送的信息，并将信息发送给处理器810进行处理。在上行方向上，处理器810对终端的数据进行处理，并通过收发装置830发送给基站。图7中的收发单元710可以由收发装置830实现。
该存储器820用于存储实现以上方法实施例，或者图7所示的处理单元720的程序，处理器810调用该程序，执行以上方法实施例的操作，以实现图7所示的处理单元720。
或者，以上处理单元720的部分或全部也可以通过集成电路的形式内嵌于该终端的某一个芯片上来实现。其中，处理单元720的某一功能可以单独实现，也将处理单元720全部的功能可以集成在一起实现。即处理单元720可以被配置成实施以上方法的一个或多个集成电路，例如：一个或多个ASIC，或，一个或多个微处理器DSP，或，一个或者多个FPGA等。
基于同一发明构思，本申请实施例中还提供了一种通信系统，由于本申请实施例中的通信系统对应的方法为本申请实施例资源分配的方法，因此本发明实施例通信系统的实施可以参见该方法的实施例，重复之处不再赘述。
本申请实施例的通信系统，包括基站和终端，参见图1所示，其中基站为图5所示的基站，终端为图7所示的终端。
从上述内容可以看出：本申请实施例中基站向第一终端发送第一指示信息，其中，第一指示信息用于指示为周期性传输第一终端的业务数据包所分配的第一资源；在当前周期第一资源发生传输资源冲突时，为第一终端分配第二资源，具体的，第二资源与第一资源为不同的传输资源；并向第一终端发送第二指示信息，其中，第二指示信息用于指示在当前周期内为传输第一终端的业务数据包所分配的第二资源。在本申请中，由于基站在第一资源发生资源冲突时，将第一终端传输的业务数据包调度到第二资源上，因此，与现有技术中丢弃其中一个数据包相比，提高了业务的性能，从而提高了用户 体验。
本领域内的技术人员应明白，本发明的实施例可提供为方法、系统、或计算机程序产品。因此，本发明可采用完全硬件实施例、完全软件实施例、或结合软件和硬件方面的实施例的形式。而且，本发明可采用在一个或多个其中包含有计算机可用程序代码的计算机可用存储介质(包括但不限于磁盘存储器、CD-ROM、光学存储器等)上实施的计算机程序产品的形式。
本发明是参照根据本发明实施例的方法、设备(系统)、和计算机程序产品的流程图和/或方框图来描述的。应理解可由计算机程序指令实现流程图和/或方框图中的每一流程和/或方框、以及流程图和/或方框图中的流程和/或方框的结合。可提供这些计算机程序指令到通用计算机、专用计算机、嵌入式处理机或其他可编程数据处理设备的处理器以产生一个机器，使得通过计算机或其他可编程数据处理设备的处理器执行的指令产生用于实现在流程图一个流程或多个流程和/或方框图一个方框或多个方框中指定的功能的装置。
这些计算机程序指令也可存储在能引导计算机或其他可编程数据处理设备以特定方式工作的计算机可读存储器中，使得存储在该计算机可读存储器中的指令产生包括指令装置的制造品，该指令装置实现在流程图一个流程或多个流程和/或方框图一个方框或多个方框中指定的功能。
这些计算机程序指令也可装载到计算机或其他可编程数据处理设备上，使得在计算机或其他可编程设备上执行一系列操作步骤以产生计算机实现的处理，从而在计算机或其他可编程设备上执行的指令提供用于实现在流程图一个流程或多个流程和/或方框图一个方框或多个方框中指定的功能的步骤。
尽管已描述了本发明的优选实施例，但本领域内的技术人员一旦得知了基本创造性概念，则可对这些实施例作出另外的变更和修改。所以，所附权利要求意欲解释为包括优选实施例以及落入本发明范围的所有变更和修改。
显然，本领域的技术人员可以对本发明进行各种改动和变型而不脱离本发明的精神和范围。这样，倘若本发明的这些修改和变型属于本发明权利要 求及其等同技术的范围之内，则本发明也意图包含这些改动和变型在内。
