本领域普通技术人员可以理解，实现上述实施例方法中的全部或部分步骤是可以通过程序来指令相关的硬件来完成，所述的程序可以存储于非暂态计算机可读取存储介质中，该程序在执行时，包括S201至S203。其中，所述的存储介质可以为ROM/RAM、磁碟、光盘等。
图4是本公开实施例提供的自动调节下行UDP灌包流量的系统框图，如图4所示，包括图2所示的包含信息获取模块10、流量计算模块20和信息发送模块30的自动调节下行UDP灌包流量的装置，以及UDP灌包服务器40。其中，流量计算模块20可以利用信息获取模块10从基站的OAM模块获取的无线小区的当前物理资源信息和已接入所述无线小区的无线终端数量及无线终端的信息，确定已接入无线小区的每个无线终端的灌包流量，并由信息发明模块30发送至UDP灌包服务器。UDP灌包服务器40可以将每个无线终端的灌包流量调整为收到的已接入无线小区的每个无线终端的灌包流量，并按照调整后的相应无线终端的灌包流量，对相应无线终端进行UDP下行灌包。
可选地，UDP灌包服务器40进行UDP下行灌包之前，需要判断灌包流量是否超过该UDP灌包服务器的灌包能力，当判断灌包流量超过该UDP灌包服务器的灌包能力，则将部分灌包流量分配给其它具有UDP灌包功能的设备。可选地， UDP灌包服务器40在判断该灌包服务器的灌包能力不能对所有无线终端进行UDP下行灌包时，启动其它具有UDP灌包功能的设备，并将超过该UDP灌包服务器的灌包能力的无线终端的灌包流量分配给所启动的设备。
通过检测无线小区和无线终端的信息的变化，确定适应于无线终端空口质量的灌包流量，并及时反馈给UDP灌包服务器，灌包服务器可以通过获取反馈的无线终端的灌包流量，自动调节UDP灌包流量，效率高，响应速度块。
图5是本公开实施例提供的总体业务处理流程图，如图5所示，包括S301-S306。：
在S301中，检测每个无线小区(一个或多个)的当前物理资源(或无线资源信息)，例如，带宽和传输模式，在TDD模式通信系统中进一步包括子帧配比。上述信息从基站侧获取。
在S302中，检测每个无线小区中接入无线终端的个数以及每个无线终端的信息，例如，无线终端的调制编码方式和无线终端的IP地址等信息。上述信息可以从基站侧获取。
在S303中，检测到上述无线小区和无线终端的信息后，即可以推算出每个无线终端需要的下行灌包的最大流量(即灌包流量)。
在S304中，反馈(例如周期性反馈)无线终端的信息和下行灌包的最大流量给UDP灌包服务器，即，将无线终端的IP地址信息和下行灌包的最大流量信息反馈给UDP灌包服务器。
在S305中，UDP灌包服务器根据反馈信息自动调整给无线终端发送UDP灌包业务的流量，以便启动针对每个无线终端的下行UDP灌包。
检测到无线小区和无线终端信息后，可以推算出每个无线终端需要的下行灌包的最大流量，周期性将终端IP信息和最大流量信息反馈给UDP灌包服务器，在UDP灌包服务器中启动针对每个无线终端下行UDP灌包。
可选地，当无线小区资源信息发生变化和/或无线小区中无线终端信息发生变化时，通过周期性反馈的方式，调整UDP灌包服务器针对每个无线终端的UDP灌包流量。
在S306中，UDP灌包服务器检测到灌包流量超过该UDP灌包服务器的负荷能力(即灌包能力或服务能力)之后，通过自动增加具有灌包能力的网元来满足灌包业务的要求。即UDP灌包服务器检测到灌包流量超过该UDP灌包服务器的负荷能力之后，能通过自动增加网元来满足灌包业务的要求。
本实施例通过将检测的无线终端在基站侧的信息反馈给UDP灌包服务器，使UDP灌包服务器能够自动调整下行灌包流量，并且自动给无线终端发起灌包。
本实施例的UDP服务器能够自动检测到灌包流量是否超过自身负荷，并在超过自身负荷时，自动增加网元数量来满足业务需求。
本实施例能够同时满足多个无线小区(跨站或站内)的UDP下行灌包要求。
图6是本公开实施例提供的网络分布图，如图6所示，包括交换机，以及通过交换机连接的多个无线基站、接入相应无线基站的用户终端(User Equipment，UE)、核心网、检测系统、灌包服务器(即UDP灌包服务器)。其中，所述检测系统包括图2所示的自动调节下行UDP灌包流量的装置，该装置与无线基站相互独立，单独设置在网络侧。可选地，所述检测系统也可以设置在每个无线基站上。
图7是本公开实施例提供的第一业务处理流程图，如图7所示，包括S401-S408。
在S401中，开始流程。
在S402中，检测系统获取无线小区信息。
在S403中，n个UE接入无线小区。
在S404中，检测系统获取每个UE的信息。
在S405中，检测系统计算每个UE的灌包流量，并将所计算的每个UE的灌包流量和IP信息传递给UDP灌包服务器。
在S406中，UDP灌包服务器开始灌包。
在S407中，移动某个UE的位置。
在S408中，当该移动位置的UE的MCS值变动达到门限时，则执行S404。
启动检测系统，检测系统获取：无线小区在近点接入多个UE，设UE个数为N；检测系统从基站侧获取需要的UE的信息。测试人员需要对所有的UE进行下行UDP灌包。
在检测系统启动灌包时，检测系统根据已经获取的无线小区的信息和UE的信息，计算出每个UE需要的灌包流量。计算所需物理量如下：
设无线小区的最大的理论流量(即最大理论流量)为ThoughtMax；
设置最大的调制编码方式(Modulation and Coding Scheme，MCS)的调制编码率(即最大调制编码率)为MaxCodeRate；
接入用户数(即接入的UE数量)为N，为了方便区分，本实施例用UEn来表示第n个UE，n表示UE的编号；
UE的当前平均MCS值(即当前平均调制编码率)为CurCodeRaten，n表示UE的编号；
设置流量偏移量Thgt_offset，该变量用来保证UDP灌包服务器启动的实际业务流量满足要求，测试过程中可以根据实际测试的效果来进行灵活调整。
单个UE的灌包流量公式如公式(1)所示，如下：
Figure PCTCN2016101465-appb-000001
在完成UE的灌包流量的计算之后，将所有UE的流量信息和IP地址信息传递给UDP灌包服务器。UDP灌包服务器根据收到的来自检测系统的信息，启动对相应UE的下行灌包业务。
其中，假设一个UE从近点移动到远点，UE在移动过程中，检测系统在检测周期内检测到此UE的平均MCS值(即平均调制编码率)降低超过预设值门限(即变化值超过预设门限值)，此时根据最新的检测到的平均MCS值，重新计算该UE的下行UDP灌包流量(参见公式(1))，并将此UE流量的IP信息和灌包流量信息重新发送给UDP灌包服务器。UDP灌包服务器接收到更新之后的终端IP信息和灌包流量信息，调整下行UDP灌包的流量信息。
图8是本公开实施例提供的第二业务处理流程图，如图8所示，包括S501-S509。
在S501中，开始流程。
在S502中，检测系统获取M个无线小区的信息。
在S503中，每个无线小区接入n个UE。
在S504中，检测系统获取每个UE的信息。
在S505中，检测系统计算每个UE的灌包流量，并将所计算的每个UE的灌包流量和IP信息传递给UDP灌包服务器。
在S506中，UDP灌包服务器检测到灌包流量超过服务能力，自动增加具有灌包功能的网元。
在S507中，UDP灌包服务器启动UDP灌包业务。
在S508中，某无线小区的某个UE的位置发生移动。
在S509中，当该移动位置的UE的MCS值变动达到门限，则执行S504。
启动检测系统，检测系统获取：多个无线小区在近点接入多个UE，设小区个数为M，每个小区用Cellm来标识，每个小区接入的UE个数用UEnumn来标识；检测系统从基站侧获取需要的UE的信息。现在需要对所有的UE做下行UDP灌包。
在检测系统启动灌包时，检测系统根据已经获取的每个无线小区的信息和接入其中的UE的信息，计算出每个UE的需要的灌包流量参见公式(1)，然后将这些信息传递给UDP灌包服务器。
UDP灌包服务器接收到检测系统的信息，如果灌包流量的请求超过UDP灌包服务器的能力，那么UDP灌包服务器启动新的网元(即能够提供UDP灌包功能的设备，例如PC或服务器)，提高灌包能力以满足灌包要求。
UDP灌包服务器启动对所有UE的下行灌包业务。
当某个无线小区的一个UE从近点移动到远点，UE在移动过程中，检测系统在检测周期内检测到该UE的MCS值降低，根据最新的检测到的MCS值，重新计算该UE的下行UDP灌包流量，并将此灌包流量信息和UE的IP信息重新发送给UDP灌包服务器。UDP灌包服务器接收到更新之后的终端IP信息和灌包流量信息，调整下行UDP灌包的流量信息。
本公开实施例能够在多无线小区测试下多UE灌包流量时提高UDP灌包效率，能够根据无线终端的状态变化自动调整下行UDP灌包流量，避免下行UDP灌包流量过高或偏低的情况，提高UDP灌包业务的灵活性，满足当前日益丰富的测试场景要求。
