Description

资源池配置和选择方法、装置、终端、基站及存储介质
本申请要求在2018年09月28日提交中国专利局、申请号为201811143359.9的中国专利申请的优先权，该申请的全部内容通过引用结合在本申请中。
技术领域
本公开涉及但不限于通信技术领域，例如涉及一种资源池配置和选择方法、装置、终端、基站及存储介质。
背景技术
随着通信技术的发展及需求的丰富，无线通信的应用场景也日益广泛，其中比较典型的应用场景是车联网(Vehicle Networking)。所谓的车联网，是车辆可以参与到无线通信中，通过利用先进的无线蜂窝通信技术，实现车与车，以及车与路侧基础设施间的实时信息交互，从而告知彼此目前的状态(包括车辆的位置，速度，加速度和行驶路径)及获知的道路环境信息，协作感知道路危险状况，及时提供多种碰撞预警信息，并防止道路交通安全事故的发生。
车联网通信的模式具体分为三种：车车通信(Vehicle-to-Vehicle Communications，V2V)，车网通信(Vehicle-to-Infrastructure Communications，V2I)和车人通信(Vehicle-to-Pedestrian，V2P)，这三类车联网通信的模式也可以统称为车对一切(Vehicle-to-Everything，V2X)通信。
V2X通信支持两种资源分配模式，分别是基站配置模式和终端自主资源选择模式。
现有终端自主资源选择模式中，基站会为多个资源池中的每一个资源池配置资源池配置信息，其中，资源池配置信息包括地理位置指示信息和信道占用比率(Channel Busy Ratio，CBR)门限值。然后基站会将每一个资源池的资源池配置信息发送给支持终端自主资源选择模式的终端。终端在接收到每一个资源池的资源池配置信息后，在需要发送数据包时，就会根据接收到的每一个资源池的资源池配置信息，以及终端当前的位置信息，每一个资源池当前的CBR值，从多个资源池中选择匹配的资源池作为发送资源池，其中CBR＝已占用资源 量/总资源量。在选择出发送资源池后，通过选择的发送资源池来发送待发送数据包。然而在此种选择发送资源池的方式中，会出现选择出来的发送资源池与待发送数据包匹配度低的情况。

具体实施方式
下面通过具体实施方式结合附图对本发明实施例作进一步详细说明。应当理解，此处所描述的具体实施例仅仅用以解释本发明，并不用于限定本发明。
实施例一：
本发明实施例提供一种资源池选择方法，参见图1，该资源池选择方法包括如下步骤。
S101、接收基站发送的多个资源池中每个资源池的资源池配置信息。资源池配置信息包括地理位置指示信息，资源池配置信息还包括以下至少之一：允许发送个数门限值；数据包尺寸信息和CBR门限值。
在本实施例中，终端可以接收基站发送的每个资源池的资源池配置信息，其中，任一资源池的资源池配置信息中都包括地理位置指示信息，任一资源池 的资源池配置信息中还包括以下至少之一：允许发送个数门限值；数据包尺寸信息和CBR门限值。其中，地理位置指示信息可以包括经度、维度等用于指示地理位置的信息。允许发送个数门限值为该资源池允许发送数据包个数的门限值，当该资源池可用资源总量除以待发送数据包大小得到的商大于为该资源池配置的允许发送个数门限值时，则待发送数据包与该资源池匹配，可以使用该资源池中的资源来发送这个待发送数据包。数据包尺寸信息包括为该资源池配置的数据包的尺寸。CBR门限值包括为该资源池配置的CBR门限值，当该资源池当前CBR值小于CBR门限值时，则选择该资源池中的资源来发送数据包，其中CBR＝已占用资源量/总资源量。
本实施例中，资源池配置信息可以包括地理位置指示信息和允许发送个数门限值。资源池配置信息也可以包括地理位置指示信息，数据包尺寸信息和CBR门限值。资源池配置信息还可以包括地理位置指示信息，允许发送个数门限值，数据包尺寸信息和CBR门限值。
本实施例中，终端可以通过***广播消息和无线传输控制(Radio Resource Control，RRC)协议专有信令中的至少一种方式接收基站发送的每个资源池的资源池配置信息。也即，终端可以通过***广播消息接收基站发送的每个资源池的资源池配置信息；终端也可以通过RRC协议专有信令接收基站发送的每个资源池的资源池配置信息；终端也可以通过***广播消息和RRC协议专有信令接收基站发送的每个资源池的资源池配置信息。终端还可以通过***广播消息接收基站发送的每个资源池的资源池配置信息，在通过***广播消息接收基站发送的每个资源池的资源池配置信息之后，终端还可以通过RRC协议专有信令接收基站发送的更新后的每个资源池的资源池配置信息。
S102、根据待发送数据包尺寸、资源池当前状态信息、当前位置信息以及每个资源池的资源池配置信息，从多个资源池中选择至少一个资源池作为发送资源池。
本实施例中，接收基站发送的每个资源池的资源池配置信息，在基站需要发送数据包时，则需要从多个资源池中选择出发送资源池来发送数据。其中，选择发送数据包的方式为：根据待发送数据包尺寸、资源池当前状态信息、当 前位置信息以及每个资源池的资源池配置信息，从多个资源池中选择至少一个资源池作为发送资源池，其中，可以选择至少一个发送资源池。其中，当前位置信息为终端当前位置信息。资源池当前状态信息可以是终端通过感知(sensing)获取的，因此，在根据待发送数据包尺寸、资源池当前状态信息、当前位置信息以及每个资源池的资源池配置信息，从多个资源池中选择发送资源池之前，还可以通过sensing判断出资源池当前状态信息。
待发送数据包的类型可以是任何类型的待发送数据包，例如，可以是半静态业务生成的数据包，也可以是动态业务生成的数据包等。待发送数据包的目标发送对象可以是任意的，例如，待发送数据包可以是发送给基站的，也可以是发送给终端的等。
待发送数据包尺寸可以包括待发送数据包大小，待发送数据包尺寸也可以包括根据待发送数据包大小确定的待发送数据包力度编号。
在待发送数据包尺寸包括待发送数据包力度编号时，则在S102中，从多个资源池中选择发送资源池之前，还应当接收基站发送的数据包力度配置信息，终端可以通过***广播消息和RRC协议专有信令中的至少一种方式接收基站发送的数据包力度配置信息。也即，终端可以通过***广播消息接收基站发送的数据包力度配置信息；终端也可以通过RRC协议专有信令接收基站发送的数据包力度配置信息；终端也可以通过***广播消息和RRC协议专有信令接收基站发送的数据包力度配置信息。终端还可以通过***广播消息接收基站发送的数据包力度配置信息，在通过***广播消息接收基站发送的数据包力度配置信息之后，终端还可以通过RRC协议专有信令接收基站发送的更新后的数据包力度配置信息。
在一些实施例中，终端可以一同接收每个资源池的资源池配置信息和数据包力度配置信息，当然，终端也可以分别接收每个资源池的资源池配置信息和数据包力度配置信息。需要说明的是，终端还可以通过其他方式接收数据包力度配置信息。
数据包力度配置信息包括多个数据包大小范围与每个数据包大小范围对应的力度编号。数据包力度配置信息可以参见下表1：
表1
力度编号 数据包大小范围
力度编号1 n1Bytes-n2Bytes
力度编号2 n3Bytes-n4Bytes
力度编号3 n5Bytes-n6Bytes
…… ……
力度编号可以是字母和数字中的至少一种，力度编号与数据包大小范围是一一对应关系，n1、n2、n3、n4、n5、n6……均为大于或等于0的整数。为了确保与待发送数据包匹配的数据包大小范围是唯一的，数据包力度配置信息中的多个数据包大小范围之间不重叠。在一些实施例中，数据包力度配置信息中，多个数据包大小范围之间的差值可以相同，即(n2-n1)＝(n4-n3)＝(n6-n5)＝……，例如，参见表2，假设数据包大小范围之间的差值均为500Bytes，数据包力度配置信息请参见表2。
表2
力度编号 数据包大小范围
0 0Bytes-500Bytes
1 501Bytes-1000Bytes
2 1001Bytes-1500Bytes
…… ……
在一些实施例中，数据包尺寸配置信息中，多个数据包大小范围之间的差值也可以不同，例如，参见表3，表3为数据包力度配置信息的一种示例：
表3
力度编号 数据包大小范围
0 0Bytes-5000Bytes
1 5001Bytes-15000Bytes
2 15001Bytes-45000Bytes
…… ……
在一些实施例中，为了确保不同大小的待发送数据包能与数据包力度配置信息中的某一数据包大小范围匹配，数据包力度配置信息中的数据包大小范围可以覆盖所有可能存在的待发送数据包的大小。需要说明的是，数据包力度配置信息包括但不限于上述几种示例。
在接收到数据包力度配置信息之后，在需要发送数据包时，终端可以根据待发送数据包的大小从数据包力度配置信息中找到与待发送数据包的大小匹配的数据包大小范围，然后将匹配的数据包大小范围对应的力度编号作为待发送数据包力度编号。例如，假设待发送数据包力度配置信息如表2所示，待发送数据包的大小为560Btytes，则根据表2，与待发送数据包的大小匹配的数据包大小范围为501Bytes-1000Bytes，501Bytes-1000Bytes对应的力度编号是1，则待发送数据包尺寸包括待发送数据包力度编号，待发送数据编号为1。
在一些实施例中，在待发送数据包尺寸信息包括待发送数据包力度编号时，资源池配置信息中的数据包尺寸信息包括数据包力度编号。
在一些实施例中，在待发送数据包尺寸信息包括待发送数据包大小时，资源池配置信息中的数据包尺寸信息包括数据包大小。
本实施例中，根据待发送数据包尺寸、资源池当前状态信息、当前位置信息以及每个资源池的资源池配置信息，从多个资源池中选择发送资源池可以包括：根据当前位置信息和每个资源池的资源池配置信息中的地理位置指示信息，从多个资源池中选择与当前位置信息匹配的至少一个资源池作为目标资源池，然后，再根据待发送数据包尺寸、资源池当前状态信息以及目标资源池的资源池配置信息，从目标资源池中选择至少一个资源池作为发送资源池。应当理解的是，目标资源池的资源池配置信息中的地理位置指示信息与终端当前地理指示信息匹配。根据待发送数据包尺寸、资源池当前状态信息、当前位置信息以及每个资源池的资源池配置信息，从多个资源池中选择发送资源池也可以包括：根据待发送数据包尺寸、资源池当前状态信息以及目标资源池的资源池配置信息，从多个资源池中选择匹配的至少一个资源池，再从匹配的资源池中选择出 与当前位置信息匹配的至少一个资源池作为发送资源池。
资源池配置信息不同，根据待发送数据包尺寸、资源池当前状态信息以及目标资源池的资源池配置信息从目标资源池中选择至少一个资源池作为发送资源池的方式也不同。
在资源池配置信息包括数据包尺寸信息和CBR门限值时，根据待发送数据包尺寸、资源池当前状态信息以及目标资源池的资源池配置信息，从目标资源池中选择至少一个资源池作为发送资源池可以包括：根据待发送数据包尺寸、资源池CBR测量值，以及目标资源池的数据包尺寸信息、CBR门限值，从目标资源池中选择出待发送数据包尺寸与数据包尺寸信息匹配的，且资源池CBR测量值与CBR门限值匹配的至少一个资源池作为可发送资源池，资源池当前状态信息包括资源池CBR测量值，资源池CBR测量值由资源池当前已占用资源量与资源池总资源量生成(即CBR测量值＝资源池当前已占用资源量/资源池总资源量)。对于资源池当前可用资源量，终端可以通过sensing判断出资源池当前已占用资源量，终端可以通过sensing判断出资源池在之前预设时间段内的平均已占用资源量来确定资源池当前已占用资源量，例如，终端可以通过sensing判断出资源池在之前1秒内的平均已占用资源量来确定资源池当前已占用资源量；终端也可以通过sensing判断出资源池在当前时刻的已占用资源量来确定资源池当前已占用资源量。当然，终端还可以通过其他方式判断出资源池当前已占用资源量。对于资源池总资源量，通常，资源池配置信息中会包括资源池总资源量，因此终端可以通过资源池配置信息判断出资源池总资源量；或者，终端可通过sensing判断出资源池总资源量，当然，终端还可以通过其他方式判断出资源池总资源量。
在待发送数据包尺寸包括待发送数据包大小，数据包尺寸信息包括数据包大小范围时，待发送数据包尺寸与数据包尺寸信息匹配可以是待发送数据包大小属于数据包大小范围，例如，假设待发送数据包尺寸为1500Bytes，资源池A的数据包大小范围为0Bytes-10000Bytes，资源池B的数据包大小范围为0Bytes-500Bytes，则待发送数据包尺寸与资源池A匹配，与资源池B不匹配；在待发送数据包尺寸包括待发送数据包力度编号，数据包尺寸信息包括力度编 号时，待发送数据包尺寸与数据包尺寸信息匹配可以是数据包尺寸信息中的力度编号中有一个力度编号与待发送数据编号一致，例如，假设资源池C的数据包尺寸信息包括的力度编号为0、1、2，资源池D的数据包尺寸信息包括的力度编号为0、1，待发送数据包力度编号为2，则待发送数据包尺寸与资源池C匹配，与资源池D不匹配。
资源池CBR测量值与CBR门限值匹配的资源池是该资源池的CBR测量值小于该资源池的CBR门限值。例如，假设资源池E的CBR测量值为50％，资源池E的资源池配置信息中的CBR门限值为60％，则资源池E的CBR测量值与CBR门限值匹配；假设资源池F的CBR测量值为80％，资源池F的资源池配置信息中的CBR门限值为40％，则资源池F的CBR测量值与CBR门限值不匹配。
根据待发送数据包尺寸、资源池CBR测量值、以及目标资源池的数据包尺寸信息、CBR门限值，从目标资源池中选择出待发送数据包尺寸与数据包尺寸信息匹配的，且资源池CBR测量值与CBR门限值匹配的资源池作为发送资源池，可以包括：根据待发送数据包尺寸以及数据包尺寸信息从目标资源池中选择出与待发送数据包尺寸匹配的至少一个资源池作为第一资源池，再从第一资源池中选择CBR测量值大于CBR门限值的至少一个资源池作为发送资源池，此处，资源池当前状态信息包括第一资源池的CBR测量值，CBR测量值根据资源池当前已占用资源量与资源池总资源量生成。或者，从目标资源池中选择出CBR测量值小于CBR门限值的至少一个资源池，再从选择出的至少一个资源池中根据待发送数据包尺寸以及数据包尺寸信息，选择匹配的至少一个资源池作为发送资源池。
在资源池配置信息包括数据包尺寸信息、CBR门限值，以及数据包尺寸信息和CBR门限值之间的映射关系时，根据待发送数据包尺寸、资源池当前状态信息以及目标资源池的资源池配置信息，从目标资源池中选择至少一个资源池作为发送资源池，可以包括：根据目标资源池的数据包尺寸信息和CBR门限值之间的映射关系，以及待发送数据包尺寸，确认出与待发送数据包尺寸匹配的第一目标CBR门限值，从目标资源池中选择出CBR测量值小于第一目标CBR 门限值的资源池作为发送资源池，资源池当前状态信息包括目标资源池的CBR测量值，CBR测量值根据资源池当前已占用资源量与资源池总资源量生成。任一资源池的资源池配置信息中的数据包尺寸信息和CBR门限值之间的映射关系可以是一一对应的，例如，参见表4，表4中，一个数据包尺寸信息对应一个CBR门限值。
表4
数据包尺寸信息 CBR门限值
数据包尺寸信息1 CBR门限值1
数据包尺寸信息2 CBR门限值2
数据包尺寸信息3 CBR门限值3
…… ……
任一资源池的资源池配置信息中的数据包尺寸信息和CBR门限值之间的映射关系，也可以是多对一的，也即多个数据包尺寸信息对应一个CBR门限值，例如，参见表5，表5中，有多个数据包尺寸信息对应一个CBR门限值，也有一个数据包尺寸信息对应一个CBR门限值。
表5
数据包尺寸信息 CBR门限值
数据包尺寸信息1、数据包尺寸信息2 CBR门限值1
数据包尺寸信息3 CBR门限值2
数据包尺寸信息4、数据包尺寸信息5 CBR门限值3
…… ……
为了更好的理解，这里以一个目标资源池为例进行说明如何确定该目标资源池是否是发送资源池，并以此可推广到多个目标资源池。假设某一目标资源池的数据包尺寸信息与CBR门限值之间的映射关系如下表6-1所示，数据包尺寸信息包括力度编号，该目标资源池当前CBR测量值为60％，假设待发送数据包尺寸为4，根据表6-1和待发送数据包尺寸，确定第一目标CBR门限值为80％，由于CBR测量值(60％)小于第一目标CBR门限值(80％)，因此，选择该目标资源池作为发送资源池；假设待发送数据包尺寸为6，根据表6-1和待发送数 据包尺寸，确定第一目标CBR门限值为40％，由于CBR测量值(60％)大于第一目标CBR门限值(40％)，因此，不选择该目标资源池作为发送资源池。
表6-1
数据包尺寸信息 CBR门限值
0、1 50％
3、4、5 80％
6 40％
…… ……
在一些实施例中，数据包尺寸信息还可以是数据包尺寸大小，参见表6-2，假设数据包尺寸信息为数据包大小范围，某一目标资源池数据包尺寸信息与CBR门限值之间的映射关系如下表6-2所示，该目标资源池当前CBR测量值为50％，假设待发送数据包尺寸为600Bytes，根据表6-2和待发送数据包尺寸，确定第一目标CBR门限值为30％，由于CBR测量值(50％)大于第一目标CBR门限值(30％)，因此，不选择该目标资源池作为发送资源池；假设待发送数据包尺寸为1500Bytes，根据表6-2和待发送数据包尺寸，确定第一目标CBR门限值为90％，由于CBR测量值(50％)小于第一目标CBR门限值(90％)，因此，选择该目标资源池作为发送资源池。
表6-2
数据包尺寸信息 CBR门限值
0Bytes-500Bytes、501Bytes-1000Bytes 30％
1001Bytes-5000Bytes 90％
10001Bytes-50000Byte 60％
…… ……
在资源池配置信息包括允许发送个数门限值时，根据待发送数据包尺寸、资源池当前状态信息以及目标资源池的资源池配置信息，从目标资源池中选择至少一个资源池作为发送资源池，可以包括：根据目标资源池当前的可用资源量和待发送数据包尺寸计算出目标资源池的可发送个数(可发送个数＝可用资源量/待发送数据包尺寸，若可用资源量除以待发送数据包尺寸的商不为整数时， 可以向下取整)，资源池当前状态信息包括目标资源池当前的可用资源量，然后从目标资源池中选择可发送个数大于允许发送个数门限值的至少一个资源池作为发送资源池。目标资源池当前的可用资源量的获取方法请参见前述当前已占用资源量的获取方法，此处不再赘述。
为了更好的理解，这里以一个目标资源池为例进行说明如何确定该目标资源池是否是发送资源池，并以此可推广到多个目标资源池。假设某一目标资源池的允许发送个数门限值是5，目标资源池当前可用资源量为10000Bytes，假设待发送数据包尺寸为1000Bytes，则可发送个数大于允许发送个数门限值，选择该资源池作为发送资源池；假设待发送数据包尺寸为5000Bytes，则可发送个数小于允许发送个数门限值，不选择该资源池作为发送资源池。
上述三种从目标资源池中选择发送资源池的方式也可以结合，例如，在资源池配置信息包括允许发送个数门限值、数据包尺寸信息和CBR门限值时，从目标资源池中选择至少一个资源池作为发送资源池，可以包括：根据待发送数据包尺寸、目标资源池当前可用资源池、资源池CBR测量值、允许发送个数门限值、数据包尺寸信息以及CBR门限值，从目标资源池中选择待发送数据包尺寸与数据包尺寸信息匹配的、CBR测量值与CBR门限值匹配的、可发送个数大于允许发送个数门限值的至少一个资源池作为发送资源池，资源池当前状态信息包括目标资源池的CBR测量值和当前可用资源量。
本实施例中，资源池配置信息还包括数据包优先级。资源池配置信息不同，根据待发送数据包尺寸、资源池当前状态信息以及目标资源池的资源池配置信息从目标资源池中选择至少一个资源池作为发送资源池的方式也不同。
在资源池配置信息包括数据包尺寸信息、CBR门限值、数据包优先级，以及，数据包优先级和CBR门限值之间的映射关系时，根据待发送数据包尺寸、资源池当前状态信息以及所述目标资源池的资源池配置信息，从目标资源池中选择至少一个资源池作为发送资源池，可以包括：根据待发送数据包尺寸以及数据包尺寸信息，从目标资源池中选择出匹配的至少一个资源池作为第二资源池；根据第二资源池的数据包优先级与CBR门限值之间的映射关系，以及待发送数据包优先级，确认出与待发送数据包优先级匹配的第二目标CBR门限值； 从第二资源池中选择CBR测量值小于第二目标CBR门限值的至少一个资源池作为发送资源池，资源池当前状态信息包括第二资源池的CBR测量值，CBR测量值根据资源池当前已占用资源量与资源池总资源量生成。待发送数据包尺寸与数据包尺寸信息匹配的确认方式、CBR测量值的获取方式请参见前述记载，此处不再赘述。任一资源池的资源池配置信息中的数据包优先级和CBR门限值之间的映射关系，可以是一一对应的，例如，参见表7，表7中，一个数据包优先级对应一个CBR门限值。
表7
数据包优先级 CBR门限值
优先级1 CBR门限值1
优先级2 CBR门限值2
优先级3 CBR门限值3
…… ……
任一资源池的资源池配置信息中的数据包优先级和CBR门限值之间的映射关系，也可以是多对一的，也即多个数据包优先级对应一个CBR门限值，例如，参见表8，表8中，有多个数据包优先级对应一个CBR门限值，也有一个数据包优先级对应一个CBR门限值。
表8
数据包优先级 CBR门限值

…… ……
为了更好的理解，这里以一个第二资源池为例进行说明如何确定该第二资源池是否是发送资源池，并以此可推广到多个第二资源池。本实施例中，假设某一第二资源池的数据包优先级和CBR门限值之间的映射关系如表8所示，该第二资源池的CBR测量值为30％，假设待发送数据包优先级为优先级3，则第二目标CBR门限值为CBR门限值2，若30％大于或等于CBR门限值2，则不 选择该第二资源池作为发送资源池；若30％小于CBR门限值2，则选择该第二资源池作为发送资源池。
在资源池配置信息包括数据包尺寸信息、CBR门限值、数据包优先级，以及数据包尺寸信息、数据包优先级和CBR门限值三者之间的映射关系时，根据待发送数据包尺寸、资源池当前状态信息以及目标资源池的资源池配置信息，从目标资源池中选择至少一个资源池作为发送资源池，可以包括：根据目标资源池的数据包尺寸信息、数据包优先级和CBR门限值三者之间的映射关系、待发送数据包尺寸，以及待发送数据包的优先级，确认出与待发送数据包尺寸、待发送数据包的优先级匹配的第三目标CBR门限值，从目标资源池中选择CBR测量值小于第三目标CBR门限值的至少一个资源池作为发送资源池，资源池当前状态信息包括目标资源池的CBR测量值，CBR测量值根据资源池当前已占用资源量与资源池总资源量生成。目标资源池的CBR测量值的获取方式请参见前述记载，此处不再赘述。在一些实施例中，一个资源池的数据包尺寸信息、数据包优先级和CBR门限值三者之间的映射关系可以是不同优先级、不同数据包尺寸信息对应不同CBR门限值，例如，参见表9，假设数据包尺寸信息为力度编号，表9中，不同优先级、不同力度编号对应不同CBR门限值。

Figure PCTCN2019108861-appb-000002
在一些实施例中，一个资源池的数据包尺寸信息、数据包优先级和CBR门限值三者之间的映射关系中，可以存在相同优先级、不同力度编号对应同一CBR门限值，例如，参见表10，表10中，存在优先级均为优先级1，力度编号0、1对应同一CBR门限值，即门限值1。
表10
Figure PCTCN2019108861-appb-000003
Figure PCTCN2019108861-appb-000004
在一些实施例中，一个资源池的数据包尺寸信息、数据包优先级和CBR门限值三者之间的映射关系中，可以存在不同优先级、不同力度编号对应一个CBR门限值，例如，参见表11，表11中，存在优先级为优先级1，力度编号为0对应的CBR门限值，与优先级为优先级2，力度编号为1对应的CBR门限值相同，即均为门限值1。
表11
Figure PCTCN2019108861-appb-000005
需要说明的是，任一资源池的数据包尺寸信息、数据包优先级和CBR门限值三者之间的映射关系不限于上述列举的方式。数据包尺寸信息、数据包优先级和CBR门限值三者之间的映射关系可以任意的，只要根据待发送数据包优先级和待发送数据包尺寸可以查找到唯一的CBR门限值即可。
值得注意的是，虽然上述示例中，数据包尺寸信息、数据包优先级和CBR门限值三者之间的映射关系中，数据包尺寸信息包括力度编号，在一些实施例中，数据包尺寸信息、数据包优先级和CBR门限值三者之间的映射关系中，数 据包尺寸信息包括数据包尺寸范围，此时，待发送数据包尺寸为待发送数据包大小。
为了更好的理解，这里以一个目标资源池为例进行说明如何确定该目标资源池是否是发送资源池，并以此可推广到多个目标资源池。本实施例中，假设某一目标资源池的数据包尺寸信息、数据包优先级和CBR门限值三者之间的映射关系如上表9所示，该目标资源池的CBR测量值为20％，待发送数据包的尺寸信息为2，待发送数据包的优先级为优先级3，查找表9，则该目标资源池的第三目标CBR门限值为门限值15，若CBR测量值(20％)大于门限值15，则不选择该资源池为发送资源池；若CBR测量值(20％)小于等于门限值15，则选择该资源池为发送资源池。
在资源池配置信息包括数据包优先级、允许发送个数门限值，以及，允许发送个数门限值与数据包优先级之间的映射关系时，根据待发送数据包尺寸、资源池当前状态信息以及目标资源池的资源池配置信息，从目标资源池中选择至少一个资源池作为发送资源池，可以包括：根据目标资源池的允许发送个数门限值与数据包优先级之间的映射关系，以及待发送数据包的优先级，确认出与待发送数据包的优先级匹配的第一目标允许发送个数门限值，选择可发送个数大于第一目标允许发送个数门限值的至少一个资源池作为发送资源池，资源池当前状态信息包括目标资源池的当前可用资源量，可发送个数根据当前可用资源量与待发送数据包尺寸生成，当前可用资源量的获取方式请参见前述记载，此处不再赘述。在一些实施例中，任一资源池的允许发送个数门限值与数据包优先级之间的映射关系可以是一一对应的，例如，参见表12，表12中，数据包优先级和允许发送个数门限值一一对应：
表12
数据包优先级 允许发送个数门限值
优先级1 允许发送个数门限值1
优先级2 允许发送个数门限值2
优先级3 允许发送个数门限值3
…… ……
在一些实施例中，任一资源池的允许发送个数门限值与数据包优先级的映射关系可以是一对多的，例如，参见表13，表13中，多个数据包优先级可以对应一个允许发送个数门限值：
表13
数据包优先级 允许发送个数门限值
优先级1、3 允许发送个数门限值1
优先级2 允许发送个数门限值2
优先级5、6、7 允许发送个数门限值3
…… ……
为了更好的理解，这里以一个目标资源池为例进行说明如何确定该目标资源池是否是发送资源池，并以此可推广到多个目标资源池。本实施例中，假设某一目标资源池的允许发送个数门限值与数据包优先级的映射关系如上表13所示，该目标资源池当前的可发送个数为6，待发送数据包优先级为优先级5，查找表13，第一目标允许发送个数门限值为允许发送个数门限值3，若可发送个数(6)小于或等于允许发送个数门限值3，则不选择该目标资源池作为发送资源池。
需要说明的是，上述资源池配置信息包括数据包优先级的三种发送资源池的选择方式也可以结合。
本实施例中，在选择出发送资源池后，可以通过发送资源池中的资源来发送待发送数据包。在通过发送资源池中的资源来发送待发送数据包时，可以通过预设规则从发送资源池中选择目标发送资源池，然后通过目标发送资源池发送待发送数据包。预设规则可以是根据发送资源池当前的可用资源量或CBR测量值，按照发送资源池当前的可用资源量从高到低的顺序从发送资源池中选择预设个数的目标发送资源池，或者按照发送资源池当前的CBR测量值从低到高的顺序从发送资源池中选择预设个数的目标发送资源池，预设个数可以是1、2、3等。在一些实施例中，在选择发送资源池的过程中若获得了发送资源池的CBR 测量值，则预设规则为根据发送资源池选择过程中获取的发送资源池的CBR测量值，按照CBR测量值从低到高的顺序从发送资源池中选择预设个数的目标发送资源池。在一些实施例中，在选择发送资源池的过程中若获得了发送资源池当前的可用资源量，则预设规则为根据发送资源池选择过程中发送资源池的当前的可用资源量，按照可用资源量从高到低的顺序从发送资源池中选择预设个数的目标发送资源池。
为了解决现有根据地理位置指示信息和CBR门限值选择发送资源池的方式中，由于在选择发送资源池时仅根据了地理位置指示信息和CBR值，因此，可能会出现待发送数据包尺寸与发送资源池不匹配的情况，例如待发送数据包尺寸大于发送资源池总资源量的情况，从而使得待发送数据包尺寸与选择出来的发送资源池匹配度低的问题。通过发明实施例提供的资源池选择方法，在某些实施过程中，终端接收基站发送的多个资源池中每个资源池的资源池配置信息，资源池配置信息包括地理位置指示信息，资源池配置信息还包括以下至少之一：允许发送个数门限值；数据包尺寸信息和CBR门限值。然后根据待发送数据包尺寸、资源池当前状态信息、当前位置信息以及每个资源池的资源池配置信息，从多个资源池中选择至少一个资源池作为发送资源池。由于资源池配置信息还包括以下至少之一：允许发送个数门限值；数据包尺寸信息和CBR门限值，因此根据待发送数据包尺寸、资源池当前状态信息、当前位置信息以及每个资源池的资源池配置信息，从多个资源池中选择出的发送资源池与待发送数据包更加匹配，从而提高了发送资源池与待发送数据包的匹配度。
实施例二：
本发明实施例提供一种资源池配置方法，参见图2，该资源池配置方法包括如下步骤。
S201、配置多个资源池中每个资源池的资源池配置信息。
资源池配置信息包括地理位置指示信息，资源池配置信息还包括以下至少之一：允许发送个数门限值；数据包尺寸信息和CBR门限值。地理位置指示信息可以包括经度、维度等用于指示地理位置的信息。允许发送个数门限值为该 资源池允许发送数据包个数的门限值。当该资源池可用资源总量除以待发送数据包大小得到的商大于为该资源池配置的允许发送个数门限值时，则待发送数据包与该资源池匹配，可以使用该资源池中的资源来发送这个待发送数据包。CBR门限值包括为该资源池配置的CBR门限值，当该资源池当前CBR值小于CBR门限值时，则选择该资源池中的资源来发送数据包，其中CBR＝已占用资源量/总资源量。数据包尺寸信息包括为该资源池配置的数据包的尺寸，其中，数据包尺寸信息可以根据该资源池的总资源量来配置。
在一些实施例中，数据包尺寸信息包括力度编号。则在配置每个资源池的资源池配置信息之前，还需要：根据数据包大小划分为多个数据包大小范围；根据多个数据包大小范围生成数据包力度配置信息，数据包力度配置信息包括多个数据包大小范围和每个数据包大小范围对应的力度编号。基站可以根据可能存在的数据包尺寸大小，将所有尺寸划分为多个数据包大小范围，多个数据包大小范围之间不重叠。力度编号可以是字母和数字中的至少一种，力度编号与数据包大小范围之间一一对应。在一些实施例中，多个数据包大小范围之间的差值可以相同，在一些实施例中，多个数据包大小范围之间的差值可以不同。例如，参见表14，表14为一种示例的数据包力度配置信息，力度编号为数字。
表14
力度编号 数据包大小范围
0 0Bytes-500Bytes
1 501Bytes-1000Bytes
2 1001Bytes-5000Bytes
3 5000Bytes-10000Bytes
4 10001Bytes-50000Byte
5 50001Byte-100000Byte
…… ……
在生成数据包力度配置信息之后，就可以根据数据包力度配置信息配置每 个资源池的数据包尺寸信息，即配置每个资源池的力度编号。在配置每个资源池的力度编号时，可以根据每个资源池的总资源量配置每个资源池的数据包尺寸信息，例如，假设数据包力度配置信息如表14所示，资源池G的总资源量为5000Bytes，资源池H的总资源量为50000Bytes，资源池I的总资源量为50000000Bytes，则这三个资源池的力度编号请参见下表15：
表15
资源池 总资源量 对应力度编号
资源池G 5000Bytes 0，1，2
资源池H 50000Bytes 0，1，2，3，4
资源池I 50000000Bytes 0，1，2，3，4，5
在生成数据包力度配置信息之后，还可以将数据包力度配置信息发送给终端。基站可以通过***广播消息和RRC协议专有信令中的至少一种方式将数据包力度配置信息发送给终端。也即，基站可以通过***广播消息将数据包力度配置信息发送给终端；基站也可以通过RRC协议专有信令将数据包力度配置信息发送给终端；基站也可以通过***广播消息和RRC协议专有信令将数据包力度配置信息发送给终端。基站还可以通过***广播消息将数据包力度配置信息发送给终端，在通过***广播消息将数据包力度配置信息发送给终端之后，基站还可以通过RRC协议专有信令将更新后的数据包力度配置信息发送给特定终端。
在一些实施例中，数据包尺寸信息可以包括数据包大小范围信息。
在一些实施例中，资源池配置信息可以包括地理位置指示信息和允许发送个数门限值。资源池配置信息也可以包括地理位置指示信息，数据包尺寸信息和CBR门限值。资源池配置信息还可以包括地理位置指示信息，允许发送个数门限值，数据包尺寸信息和CBR门限值。
在一些实施例中，资源池配置信息包括地理位置指示信息、数据包尺寸信息、CBR门限值，以及数据包尺寸信息和CBR门限值之间的映射关系，也就是说，基站会根据数据包尺寸信息设置CBR门限值。任一资源池的资源池配置信 息中的数据包尺寸信息和CBR门限值之间的映射关系，可以是一一对应的，例如，参见表4，表4中，一个数据包尺寸信息对应一个CBR门限值。任一资源池的资源池配置信息中的数据包尺寸信息和CBR门限值之间的映射关系，也可以是多对一的，也即多个数据包尺寸信息对应一个CBR门限值，例如，参见表5，表5中，有多个数据包尺寸信息对应一个CBR门限值，也有一个数据包尺寸信息对应一个CBR门限值。数据包尺寸信息可以是力度编号，也可以是数据包大小范围。
在一些实施例中，资源池配置信息还包括数据包优先级。
在一些实施例中，资源池配置信息包括数据包尺寸信息、CBR门限值、数据包优先级、地理位置指示信息，以及数据包优先级和CBR门限值之间的映射关系。数据包优先级和CBR门限值之间的映射关系可以是一一对应的，例如，参见表7，表7中，一个数据包优先级对应一个CBR门限值。任一资源池的资源池配置信息中的数据包优先级和CBR门限值之间的映射关系，也可以是多对一的，也即多个数据包优先级对应一个CBR门限值，例如，参见表8，表8中，存在多个数据包优先级对应一个CBR门限值，也存在一个数据包优先级对应一个CBR门限值。
在一些实施例中，资源池配置信息包括数据包尺寸信息、CBR门限值、数据包优先级、地理位置指示信息，以及数据包尺寸信息、数据包优先级和CBR门限值三者之间的映射关系，也就是说，基站会根据数据包尺寸信息和数据包优先级设置不同的CBR门限值。一个资源池的数据包尺寸信息、数据包优先级和CBR门限值三者之间的映射关系可以是不同优先级、不同数据包尺寸信息对应不同CBR门限值，例如，参见表9，假设数据包尺寸信息为力度编号，表9中，不同优先级、不同力度编号对应不同CBR门限值。在一些实施例中，一个资源池的数据包尺寸信息、数据包优先级和CBR门限值三者之间的映射关系中，可以存在相同优先级、不同力度编号对应同一CBR门限值，例如，参见表10，表10中，存在优先级均为优先级1，力度编号0、1对应同一CBR门限值，即均为门限值1。在一些实施例中，一个资源池的数据包尺寸信息、数据包优先级和CBR门限值三者之间的映射关系中，可以存在不同优先级、不同力度编号对 应一个CBR门限值，例如，参见表11，表11中，存在优先级为优先级1，力度编号为0对应的CBR门限值，与优先级为优先级2，力度编号为1对应的CBR门限值相同，即均为门限值1。
在一些实施例中，资源池配置信息包括数据包优先级、允许发送个数门限值、地理位置指示信息，以及允许发送个数门限值与数据包优先级之间的映射关系，也就是说，基站会根据数据包优先级设置允许发送个数门限值。在一些实施例中，任一资源池的允许发送个数门限值与数据包优先级之间的映射关系可以是一一对应的，例如，参见表12，表12中，数据包优先级和允许发送个数门限值一一对应。在一些实施例中，任一资源池的允许发送个数门限值与数据包优先级之间的映射关系可以是一对多的，例如，参见表13，表13中，多个数据包优先级可以对应一个允许发送个数门限值。
S202、将每个资源池的资源池配置信息发送给终端。
基站可以通过***广播消息和RRC协议专有信令中的至少一种方式将每个资源池的资源池配置信息发送给终端。也即，基站可以通过***广播消息将每个资源池的资源池配置信息发送给终端；基站也可以通过RRC协议专有信令将每个资源池的资源池配置信息发送给终端；基站也可以通过***广播消息和RRC协议专有信令将每个资源池的资源池配置信息发送给终端。基站还可以通过***广播消息将每个资源池的资源池配置信息发送给终端，在通过***广播消息将数据包力度配置信息发送给终端之后，基站还可以通过RRC协议专有信令将更新后的每个资源池的资源池配置信息发送给特定终端。
本实施例中，基站可以将数据包力度配置信息和每个资源池的资源池配置信息一同发送给终端，当然，也可以将数据包力度配置信息和每个资源池的资源池配置信息分别发送给终端。
为了解决现有根据地理位置指示信息和CBR选择发送资源池的方式，导致待发送数据包尺寸与发送资源池不匹配的情况，例如待发送数据包尺寸大于发送资源池总资源量的情况，从而导致选择出来的发送资源池无法满足传输需求的问题。通过本发明实施例提供的资源池配置方法，在某些实施过程中，基站配置多个资源池中每个资源池的资源池配置信息，资源池配置信息包括地理位 置指示信息，资源池配置信息还包括以下至少之一：允许发送个数门限值；数据包尺寸信息和CBR门限值。然后将每个资源池的资源池配置信息发送给终端。由于资源池配置信息还包括以下至少之一：允许发送个数门限值；数据包尺寸信息和CBR门限值，因此根据每个资源池的资源池配置信息，从多个资源池中选择出的发送资源池与待发送数据包更加匹配，提高了发送资源池与待发送数据包的匹配度。
