Description
本申请要求在2014年1月24日提交中国专利局、申请号为201410035808.3、发明名称为“一种网络参数获取方法、装置及设备”的中国专利申请的优先权,其全部内容通过引用结合在本申请中。
本发明涉及无线通信技术领域,尤其涉及一种网络参数获取方法、装置及设备。
长期演进(LTE,Long Time Evolution)启动了针对小数据包类业务的节省信令开销及降低终端功耗的标准化工作。小数据包类业务主要包括机器类型通信(MTC,machine-type communication)的小数据包业务,以及移动终端上的一些小数据包业务(如QQ业务、微信业务等)。小数据包类业务由于传输的数据包大小很小,发送一个数据包需要消耗许多空口信令,而引起信令开销过大。另外,小数据包类业务的频繁传输也会导致移动终端功耗过大的问题。针对上述两个问题,第三代合作伙伴计划(3rd Generation Partnership Project,3GPP)在研究阶段提供了很多种方案,但最后进入标准化阶段的方案仅包括引入节能子状态(针对MTC超低功耗需求,通过节能子状态来实现超长待机),以及核心网提供辅助信息的长保连接态方案(通过终端或网络提供业务辅助信息来合理配置网络参数,实现节能及节省信令开销)。
目前,对于进入连接态的终端,基站没有相关信息来帮助其进行网络参数(包括DRX参数、连接释放定时器(timer))的配置,使得基站只能为全小区配置相同的网络参数,而不是根据终端特定的业务特性进行配置,因此难以达到节省信令开销和降低终端功耗的目的。

不当限定。在附图中:

以下结合说明书附图对本发明的优选实施例进行说明,应当理解,此处所描述的优选实施例仅用于说明和解释本发明,并不用于限定本发明,并且在不冲突的情况下,本发明中的实施例及实施例中的特征可以相互组合。
发明人在发明过程中发现,解决上述技术问题的一种可能的解决方案是基站统计每个终端的业务特性,然后据此来配置网络参数。然而,由于终端相关信息在终端进入空闲态时即会释放掉,使得终端在下次进入连接态后基站没有相关信息来做配置,只能进行盲配置。同时,由于大部分的连接建立是来自于背景业务或心跳包或业务更新,经过短暂的交互后终端即进入空闲态,基站在这段时间内可以统计的信息很少,而且无法统计上次连接建立到下次连接建立的包时延信息,所以难以有效地据其进行网络参数配置。
鉴于此,本发明实施例提供了一种网络参数获取方法,通过UE(终端)或者基站收集业务相关辅助信息,在连接释放时上传至MME(移动管理性实体),MME自身也可以收集一定业务相关辅助信息或者MME还可以从SGW(信令网关)处获得一些业务相关辅助信息,当UE在下次进入连接态时,基站可以从MME下载其保存的业务相关辅助信息,并根据下载的业务相关辅助信息为终端配置网络参数。
如图1所示,为本发明实施例提供的网络参数获取方法的实施流程示意图,包括以下步骤:
S101、基站从移动性管理实体MME获得终端对应的业务相关辅助信息;
其中,业务相关辅助信息可以是按业务或QCI(服务质量等级指示)来统计,也可以是不区分统计。具体内容可以包括以下信息中的至少一种或者任意组合:业务类型信息(如果区分业务进行统计时可以包括)、业务方向信息(上行业务/下行业务,如果区分业务方向进行统计时可以包括)、业务时延要求信息(如果不区分业务或者按QCI进行统计时,则给出最严的时延要求)、业务速率要求信息(如果不区分业务或者按QCI进行统计时,则给出最严的速率要求)、上次连接最后一个数据包(如果区分上行业务/下行业务进行统计时,则分别给出上次连接最后一个上行数据包/下行数据包)的到达时间信息和一次连接释放与下一次连接建立的时间间隔信息。
具体实施时,相关辅助信息还包括以下信息中的一种或者任意组合(具体实施时,可以分上行/下行进行统计,也可以不区分上/下行进行统计):第一类型信息、第二类型信息、第三类型信息、第四类型信息、第五类型信息、第六类型信息和第七类型信息。
第一类型信息包括以下信息中的至少一种:一个burst内相邻两个数据包到达时间间隔的最大值、一个burst的持续时间、一个burst组包含的burst数量的平均值、一个burst组内相邻两个burst到达时间间隔的最大值和平均值、相邻两个burst组到达时间间隔以及数据包大小信息。其中,burst和burst组的划分准则预先设定。
较佳的,如何划分burst和burst组可以依据数据包到达时间间隔进行划分,例如,可以规定数据包到达时间间隔在多大范围内属于一个burst,到达时间间隔在多大时延范围内的burst属于一个burst组。
较佳的,数据包大小信息可以但不限于包括在统计周期内的数据包平均大小信息或者在统计周期内各数据包大小的CDF(累积函数分布)信息。
第二类型信息包括:相邻两个数据包到达时间间隔的分布信息。
其中,相邻两个数据包到达时间间隔的分布信息可以是CDF信息,也可以是统计每个时间间隔区间的概率。
较佳的,可以按照以下表1所示的形式进行统计(该信息既可以是分业务(或QCI)进行统计,也可以是所有业务统计一个总的):
表1
第三类型信息包括:相邻两个数据包到达时间间隔均值信息。
具体实施时,第三类型信息包括还可以包括相邻两个数据包到达时间间隔的波动范围信息。其中,第三类型信息可以对比较规则类业务进行统计。
第四类型信息包括以下信息中的至少一种:一次上行数据包与之后最近一次下行数据包发送的时间间隔信息(可以为CDF信息或者时间间隔最大值);或者连续两次下行数据包发送的时间间隔信息(可以为CDF信息或者时间间隔最大值);或者是否存在下行数据包发送之前无上行数据包发送的指示信息。
具体实施时,还可以结合第一类型信息或者第二类型信息/第三类型信息/第四类型信息/第五类型信息进行统计。
第五类型信息包括:按数据包到达时间间隔区间记录的数据包的到达时间信息,具体实施时,还可以设定每个区间记录的最大数目,以及时间间隔区间的最大数目。
具体实施时,可以将数据包到达时间间隔划分为一定的区间(例如标准定义好数据包到达时间间隔区间的可能取值,或由实现决定如何划分区间),针对每一区间,仅记录最近N个与上一数据包到达时间间隔落在该范围内的数据包的到达时间(比如:15时30分20秒)。具体实施时,也可以不划分区间,记录所有数据包的到达时间,直到到达记录上限为止。
较佳的,可以按照表2所示的形式进行统计:
表2
| 数据包到达时间间隔区间(s或ms) | 数据包到达时间列表(列表大小N) |
| A1~B1 | |
| A2~B2 | |
| … |
第六类型信息包括:针对数据包到达时间间隔区间记录的、相邻数据包到达时间间隔属于该数据包到达时间间隔区间的发生频率信息以及上一次更新该发生频率信息的时间信息。
具体实施时,可以将数据包到达时间间隔划分为一定的区间(例如标准定义好数据包到达时间间隔区间的可能取值,或由实现决定如何划分区间),针对每一区间,记录一段时间内数据包到达时间间隔落在该区间的频率,以及上次更新该值的时间。较佳的,可以按照表3所示的形式进行统计:
表3
| 数据包到达时间间隔区间(s或ms) | 发生频率(如次数/小时) | 上次更新时间 |
| A1~B1 | ||
| A2~B2 | ||
| … |
较佳的,可以按照以下方法对表3进行更新:
针对任一数据包到达时间间隔区间,按照以下方法确定在指定时间范围内相邻数据包到达时间间隔属于该数据包到达时间间隔区间的频率:
步骤一、针对任一数据包到达时间间隔区间,若当前数据包与上一数据包的到达时间间隔属于该数据包到达时间间隔区间时,确定当前数据包的到达时间;
步骤二、确定上一次更新该数据包到达时间间隔区间对应的频率信息的时间;
步骤三、按照以下公式确定本次数据包到达时间间隔属于该数据包到达
时间间隔区间的频率:次数/小时;并按照以下公式确定在指定时间范围内相邻数据包到达时间间隔属于该数据包到达时间间隔区间的频率:α*f1+(1-α)*f1',其中:T为频率的统计周期大小;t1为当前数据包的到达时间;t2为上一次更新该数据包到达时间间隔区间对应的频率信息的时间;α为预先设定的本次数据包到达时间间隔属于该数据包到达时间间隔区间的频率对应的权重;f1为本次数据包到达时间间隔属于该数据包到达时间间隔区间的发生频率;f1'为当前记录的该数据包到达时间间隔区间对应的发生频率。
例如,以统计周期为1小时为例,当时刻A(精确到秒)一个数据包(该数据包到达时间间隔落在区间(A1,B1))到达后,查看该(A1,B1)区间上次更新时间为B(精确到秒),则本次采样得到的数据包到达时间间隔落在区间(A1,B1)的发生频率为3600/(A-B)次数/小时;假设本次采样的权重为0.1,则数据包到达时间间隔落在区间(A1,B1)的发生频率=0.9*上次记录的发生频率+0.1*本次计算得到的发生频率。
第七类型信息包括:上一统计周期的统计结果和当前统计周期的统计数据,其中,上一统计周期的统计结果包括针对数据包到达时间间隔区间记录的、在上一统计周期内相邻数据包到达时间间隔属于该数据包到达时间间隔区间的发生频率信息,当前统计周期的统计数据包括针对数据包到达时间间隔区间记录的、在当前统计周期内相邻数据包到达时间间隔属于该数据包到达时间间隔区间的发生次数信息、当前统计周期的起始时间信息。
具体实施时,当前统计周期的统计数据还可以包括当前统计周期信息,若不包括时,则按照默认周期进行统计。
具体实施时,可以按照表4所示的形式进行统计,左边“上一统计周期的统计结果”部分代表已根据之前一个统计周期的结果统计出的数据包落在每个数据包到达时间间隔区间的发生频率;右侧“当前统计周期的统计数据”表示本次统计周期内各数据包到达时间间隔区间累计发生次数、当前统计周期信息以及本次统计起始时间。
表4
较佳的,可以按照以下方法更新第七类型信息:
在当前统计周期结束后,针对预设的每一数据包到达时间间隔区间,按照以下公式更新该数据包到达时间间隔区间对应的发生频率信息:β*f2+(1-β)*f2',其中:β为当前统计周期内相邻数据包到达时间间隔属于该数据包到达时间间隔区间的发生次数对应的权重;f2为当前统计周期内相邻数据包到达时间间隔属于该数据包到达时间间隔区间的发生次数;f2'为上一统计周期内相邻数据包到达时间间隔属于该数据包到达时间间隔区间的发生频率。
具体的,对于任一数据包到达时间间隔区间,在当前统计周期内,统计其发生次数,在当前周期统计完成后,更新“上一统计周期的统计结果”中的发生频率,设当前周期统计的权重为a,则发生频率=(1-a)*发生频率+a*“当前统计周期的统计数据”中的发生次数。(需要说明的是,如果统计周期与发生频率的统计时间不匹配,则还需进行一定的转换)。然后,将“当前统计周期的统计数据”的本次统计起始时间设为当前时间,发生次数设为0。
例如,设定的统计周期为10s,在10s内终端与基站有5次连接释放操作,则针对每一次连接释放,均按照表4形式统计当前统计周期数据,其中,发生次数为根据各次统计结果累计的发生次数。
S102、基站根据获得的业务相关辅助信息为终端配置网络参数。
具体实施时,上述网络参数可以但不限于包括DRX(非连续接收)参数
和连接释放timer(定时器),其中,DRX(非连续接收)参数包括drx-InactivityTimer,onDurationTimer,longDRX-Cycle,shortDRX-Cycle,drxShortCycleTimer。
具体实施时,对于longDRX-Cycle参数,longDRX-Cycle的设置通常应满足longDRX-Cycle<业务时延要求(如果有多个业务,则业务时延要求应取时延要求最苛刻的业务时延要求)。但对于第三类型信息和第四类型信息可以例外处理。
较佳的,可以按照以下方式配置longDRX-Cycle参数:根据业务时延要求信息,配置所述longDRX-Cycle参数小于业务时延要求;若包含多个所述业务时延要求信息时,配置所述longDRX-Cycle参数小于最低的业务时延要求;或者根据第三类型信息,配置所述longDRX-Cycle参数小于相邻两个数据包到达时间间隔的最小值;或者若根据第四类型信息确定不存在下行数据包发送之前无上行数据包发送的指示信息,且连续两次下行数据包发送的时间间隔和一次上行数据包发送与之后最近一次下行数据包发送的时间间隔均小于业务时延要求(或者虽大于业务时延要求,但远小于连接释放timer),可按标准支持的最大DRX周期配置longDRX-Cycle参数。
具体实施时,对于drx-InactivityTimer参数或者onDurationTimer参数,可以依据于业务的burst特性配置,较佳的,可以依据下行业务的burst特性配置。
具体实施时,可以按照以下方式配置drx-InactivityTimer参数或者onDurationTimer参数:根据第一类型信息,配置drx-InactivityTimer参数或者onDurationTimer参数大于相邻两个数据包到达时间间隔的最大值,较佳的,可以设置onDurationTimer及drx-InactivityTimer略大于一个burst内数据包到达时间间隔的最大值;或者
根据第三类型信息,配置drx-InactivityTimer参数或者onDurationTimer参数大于相邻两个数据包到达时间间隔的波动范围,较佳的,配置onDurationTimer及drx-InactivityTimer略大于数据包到达时间间隔的波动范围
即可;或者
根据第四类型信息,配置所述drx-InactivityTimer参数或者onDurationTimer参数大于一次上行数据包与之后最近一次下行数据包发送的时间间隔和连续两次下行数据包发送的时间间隔中的最大值,较佳的,可以配置onDurationTimer及drx-InactivityTimer略大于一次上行数据包发送与之后的最近一次下行数据包发送的时间间隔和连续两次下行数据包发送的发送时间间隔中的最大值;或者
根据第二类型信息或者第五类型信息或者第六类型信息或者第七类型信息,配置drx-InactivityTimer参数或者onDurationTimer参数大于预设的数据包到达时间间隔,其中,预设的数据包到达时间间隔小于longDRX-Cycle。较佳的,可以将一定数据包到达时间间隔时间t(t<longDRX-Cycle)范围内的数据包归为一个burst,设置onDurationTimer与drx-InactivityTimer参数略大于t。
具体实施时,可以按照以下方式配置drxShortCycleTimer参数,根据第一类型信息,配置drxShortCycleTimer参数为一个burst组内相邻两个burst到达时间间隔的平均值;或者根据第二类型信息或者第五类型信息或者第六类型信息或者第七类型信息,按照以下方法配置drxShortCycleTimer参数:设定第一burst到达时间间隔,所述第一burst到达时间间隔大于预设的数据包到达时间间隔小于longDRX-Cycle;确定数据包到达时间间隔属于预设的数据包到达时间间隔和第一burst到达时间间隔之间的概率;按照以下公式确定一个longDRX-Cycle内出现的burst的数量:若n>1,配置drxShortCycleTimer参数为n,其中:n表示一个longDRX-Cycle内出现的burst的数量;p表示数据包到达时间间隔属于预设的数据包到达时间间隔和第一burst到达时间间隔之间的概率;t1表示第一burst到达时间间隔。其中,t1的选取应尽量涵盖大多数[t,longDRX-Cycle]范围内的值,但也不宜过大,以免影响包传输时延,其中,t表示预设的数据包到达时间间隔。
具体实施时,对于shortDRX-Cycle参数的配置可以分为以下几种情况:
对于第一类型信息,可以配置shortDRX-Cycle参数为一个burst组内相邻两个burst到达时间间隔的平均值;
对于第三类型信息或者第四类型信息,无需配置shortDRX-Cycle参数;
对于第二类型信息或者第五类型信息或者第六类型信息或者第七类型信息,可以参照上述配置drxShortCycleTime参数的方式,若n>1时,对shortDRX-Cycle进行配置,且配置shortDRX-Cycle参数为t1。
对于连接释放timer,本发明实施例中,主要依据第三类型信息/第五类型信息/第六类型信息/第七类型信息来确定,具体的,可以分为以下几种情况进行配置:
确定终端处于连接态时,根据第三类型信息,配置连接释放timer大于相邻两个数据包到达时间间隔信息。较佳的,对于第三类型信息,先依据数据包到达时延,终端移动速率来确定是保持终端在连接态还是释放连接,如果保持连接态,则连接释放timer应略大于包到达时间间隔最大值。
具体实施时,还可以根据第五类型信息或者第六类型信息或者第七类型信息配置连接释放timer。较佳的,对于第六类型信息或第七类型信息,当确定了每个到达时间间隔区间的发生频率后,即可知道如果把RRC连接释放timer设置比其小后,空闲态到连接态转换的发生频率(将所有比该连接释放timer大的包到达时间间隔的频率加起来即可),也即终端保持连接态的时间长度,然后即可知道切换的信令开销以及空闲态连接态转换的信令开销,从而来选择合适的RRC连接释放timer。对于第五类型信息,在获得第六类型信息的发生频率后,即可按第六类型信息所述方式选择连接释放timer。
具体实施时,业务相关辅助信息可以由终端,或者基站或者MME进行统计。其中:终端可以按照预设的统计周期统计除第六类型信息和第七类型信息以外的业务相关辅助信息并上报。若终端进行统计时,既可以在终端处于连接态时进行统计,也可以在终端处于空闲态时进行统计。较佳的,终端在进行业务相关辅助信息统计时,可以针对上行业务和下行业务分别进行统计,
也可以不进行区分一并进行统计。
较佳的,对于第一类型信息,终端按照MME发送的burst和burst组的划分准则或者按照基站广播的burst和burst组的划分准则进行统计,具体下发的burst和burst组的划分准则可以为数据包到达间隔在多大范围内属于一个burst,burst到达间隔在多大时延范围内的burst属于一个burst组,也可以由终端实现。其中,若有MME发送时,burst和burst组的划分准则携带在MME向终端发送的附着请求应答消息或者TAU(跟踪区更新)消息中。
具体实施时,也可以由基站统计业务相关辅助信息,若由基站进行统计,基站只能在终端处于连接态时进行统计,在连接释放时将统计到的相关信息上报给MME。具体的,基站可以针对每一终端,按照预先配置的统计周期,在该终端处于连接态时统计上述的业务相关辅助信息;在连接释放时,将统计的业务相关辅助上报给MME。更佳的,基站在连接释放时,还可以将连接释放timer一并上报给MME。
具体实施时,基站在进行业务相关辅助信息的统计时,可以针对上行业务和下行业务分别进行统计,也可以不区分一并进行统计。
以下以基站确定一次连接建立最后一个数据包和下次连接第一个数据包之间的时间间隔为例,较佳的,基站可以按照以下两种方式中的任一种确定一次连接建立最后一个数据包和下次连接第一个数据包之间的时间间隔:
方式一
基站根据记录的上次连接最后一个(上行/下行,如果分上/下行统计)数据包的到达时间,以及本次连接第一个(上行/下行,如果分上/下行统计)数据包的到达时间(若是下行数据包,就是基站收到MME paging时刻;若是上行数据包,就是基站收到UE的随机接入preamble时刻),来计算这两个数据包的到达时间间隔。
方式二
基站根据连接释放到连接建立的时间间隔信息、连接释放timer值,构成完整的一个终端业务的数据包到达时间间隔信息(一次连接建立中最后一个
包与下次连接建立中第一个包间的时间间隔=连接释放timer+连接释放到连接建立的时间间隔)。需要说明的是,通过方式二进行统计的话,一次连接建立中最后一个数据包与下次连接建立中第一个数据包间的时间间隔只能获得上下行混合的业务特性,而无法区分出上下行。
具体的,针对不同的统计方式,基站可以按照以下方法确定一次连接建立最后一个数据包和下次连接第一个数据包之间的时间间隔:1)针对上行业务,确定上次连接最后一个上行数据包的到达时间与本次连接第一个上行数据包的到达时间之间的时间间隔为一次连接建立最后一个数据包和下次连接第一个数据包之间的时间间隔;2)针对下行业务,确定上次连接最后下行数据包的到达时间与本次连接第一个下行数据包的到达时间之间的时间间隔为一次连接建立最后一个数据包和下次连接第一个数据包之间的时间间隔;3)针对上下行混合业务,确定上次连接最后一个数据包的到达时间与本次连接第一个数据包的到达时间之间的时间间隔为一次连接建立最后一个数据包和下次连接第一个数据包之间的时间间隔。
针对上下行混合业务,基站还可以确定上一次连接释放timer与上一次连接释放到本次连接建立之间的时间间隔之和为一次连接建立最后一个数据包与下次连接建立第一个数据包之间的时间间隔。
需要说明的是,如果是上行数据包,则最后一个数据包为基站收到终端的随机接入preamble时刻,若是下行数据包,则最后一个数据包为基站收到MMEpaging时刻。
具体实施时,还可以由MME获得业务相关辅助信息,其中,MME可以自行统计一次连接释放与下一次连接建立的时间间隔信息,其余信息MME可以从SGW(网关)处获得。较佳的,MME在统计一次连接释放与下一次连接建立的时间间隔信息时可以针对上行业务和下行业务分别进行统计,也可以不进行区分一并进行统计;SGW在统计除一次连接释放与下一次连接建立的时间间隔信息以外的其它信息时也可以针对上行业务和下行业务分别进行统计,也可以不进行区分一并进行统计。
为了更好的理解本发明实施例,以下结合终端与基站建立RRC连接过程对本发明实施例提供的网络参数获取方法的实施流程进行说明,如图2所示,终端与基站建立RRC连接,可以包括以下步骤:
S201、终端与基站建立RRC连接。
其中,终端还可以在连接建立时提供业务相关辅助信息,速度相关信息(如小区重选历史信息,从GPS等测速模块获得的速度信息,或终端空闲态粗略的移动速度估计)。
业务相关辅助信息可以由应用层提供给NAS(非接入层)层,或者由NAS层或AS(接入层)层自行统计。若是由NAS或AS层统计,则无论终端在空闲态、连接态均需要统计,并进行更新。统计时可以按业务或者QCI进行统计,也可以所有业务一起进行统计。上行或下行可以分开统计,也可以一起进行统计。在统计时,可以在获得一定数量采样点后,获取时延的CDF,或按一定准则来划分burst,burst组,划分准则可以是MME在附着或TAU时配给终端或基站通过广播方式广播(配置内容可以是数据包到达间隔在多大范围内属于一个burst,burst到达间隔在多大时延范围内的burst属于一个burst组),或终端实现。当终端再次获取一定采样点后,可以更新统计数据。更新方法可以是按CDF进行合并,或新的统计与旧的统计的加权平均。
S202、基站发送初始UE消息给MME。
MME统计针对该终端的从一次连接释放到下一次连接建立的时间间隔统计信息(比如采用类似形式二的CDF形式,或记录最近几次的时间间隔)。在统计时间间隔时,MME可以结合连接建立的原因,比如只统计因服务请求发起的连接建立,不统计因TAU发起的连接建立、因附着发起的连接建立。另外,MME还可以向SGW索要针对该终端的业务相关辅助信息统计,SGW的统计可以是MME之前配置的,SGW自己进行统计,或从PGW那里获取。MME向SGW索要信息可以是在收到基站的初始UE消息后,也可以是在基站专门向MME请求业务相关辅助信息后,还可以是MME定期向SGW索要,或SGW定期(或事件触发)向MME汇报。
S203、MME向基站反馈初始上下文建立请求。
具体实施时,在MME向基站反馈的初始上下文建立请求中,可以包括针对该终端的从一次连接释放到下一次连接建立(如果是下行业务触发连接建立,可以是到寻呼时刻)的时间间隔统计信息、连接释放timer信息、业务相关辅助信息、用户订阅信息等。
需要说明的是,连接释放timer是基站维护的,当终端一段时间内无数据发送,该定时器就会超时,基站便释放UE连接。
S204、基站根据MME、UE提供的辅助信息,合理配置网络参数。
其中,网络参数包括DRX参数(drx-InactivityTimer,onDurationTimer,longDRX-Cycle,shortDRX-Cycle,drxShortCycleTimer),连接释放timer等。
具体的,对于一次连接建立中最后一个数据包与下次连接建立第一个数据包间的时间间隔,有两种统计方法:
1.根据记录的上次连接最后一个(上行/下行,如果分上下行统计)数据包的包到达时间,以及本次连接第一个(上行/下行,入股份上下行统计)数据包的到达时间(若是下行包,就是基站收到MME paging时刻;若是上行包,就是基站收到UE的随机接入preamble时刻),来计算这两个数据包的到达时间间隔。
2.根据连接释放到连接建立的时间间隔统计信息、连接释放timer值,构成完整的一个终端业务的包到达时间间隔信息(一次连接建立中最后一个包与下次连接建立中第一个包间的时间间隔=连接释放timer+连接释放到连接建立的时间间隔)。需要说明的是,通过该种方式的统计,一次连接建立中最后一个包与下次连接建立中第一个包间的时间间隔只能获得上下行混合的业务特性,而无法区分出上下行。
如果业务相关辅助信息是UE侧或SGW直接统计,则无需与连接释放到连接建立的时间间隔统计信息结合起来即可获得完整的包到达时延信息。
S205、基站收到终端配置完成反馈后,发送初始上下文建立完成给MME。
S206、对连接态终端,可以随时提供更新的辅助信息给基站,基站也同
样可以统计该终端本次连接期间的上下行业务特性,然后更新业务相关辅助信息。
统计方法类似于步骤S201中的NAS或AS的统计,并在连接释放时将该信息上报给MME,同时还可以上报连接释放timer信息。具体可以通过UE CONTEXT RELEASE REQUEST消息,或UE CONTEXT RELEASE COMPLETE消息捎带。如果发生切换,则原基站将该信息通过切换请求发送给目标基站。如果是S1切换,则可以由MME提供给目标基站。
需要说明的是,本发明实施例不仅适用于单一的业务,而且同样适用于多个业务构成的混合业务。
