Description

一种信息交互方法及装置
本申请要求在2015年6月3日提交中国专利局、申请号为201510300582.X、发明名称为“一种信息交互方法及装置”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。
技术领域
本发明涉及通信技术领域,尤其涉及一种信息交互方法及装置。
背景技术
在长期演进(Long Term Evolution,LTE)系统中,为用户设备(User Equipment,UE)提供接入服务的演进基站(evolved Node B,eNB)之间、以及eNB与核心网节点之间都采用有线连接的方式。其中,eNB之间通过X2接口进行信息交互。由于X2接口的时延较长,一般在20ms量级,因此eNB之间通过X2接口交互的信息一般为半静态的信息,由于无法进行动态信息的交互,eNB之间不能实现较为动态的协调协作。
为了提高数据传输速率及小区吞吐量,在LTE系统中引入了中继节点(Relay Node,RN)。RN通过施主基站(donor evolved NodeB,DeNB)接入到核心网,与核心网节点之间没有直接的有线接口,在此架构下,用户设备(User Equipment,UE)与RN之间通过无线接口Uu口通信,RN与DeNB之间可以通过无线接口Un口通信,如图1所示。RN与DeNB之间进行下行数据传输时,DeNB首先需要向RN发送控制信令,其中包含对RN的下行调度的信息,之后才能进行下行数据传输;同理,RN与DeNB之间进行上行数据传输时,RN首先需要向DeNB发起上行传输请求,在获得上行传输资源后进行上行数据传输。
在超密集网络中,不同eNB之间的覆盖存在着较大的交集、eNB之间距离较近,为建立eNB之间的无线接口提供了可能性。在超密集接入点部署的场景中,如果eNB之间能够通过无线接口进行交互,则相对于现有的X2接口能够很好地降低时延,提高eNB之间的信息交互效率。
eNB之间若要实现空口传输,可以复用上述RN与DeNB之间的空口传输过程。但是,eNB之间的协调通常不仅限于两个eNB之间,一般情况下,相邻eNB之间都需要进行资源占用和数据传输的协调,如果复用上述RN与DeNB之间的空口传输过程,则需要eNB之间进行两两交互,比如,eNB1、eNB2和eNB3之间进行协调时,需要eNB1与eNB2 之间、eNB1与eNB3之间、以及eNB2与eNB3之间分别进行信息交互。
显然,上述交互方式效率较低,将会严重影响eNB等接入点之间的协调协作。

具体实施方式
在本发明实施例提供的技术方案中,发送AP确定向接收AP发送信息的空口广播资源;在确定的空口广播资源上,以广播形式向接收AP发送信息。采用本发明实施例提供的技术方案,AP之间不仅可以进行空口传输,还可以不仅限于两个AP之间的通信,一个AP可以采用广播形式,将自身的协调信息发送给所有需要与之进行信息交互的相邻AP, 从而可以提高AP之间进行协调协作的效率。
本发明实施例中的AP可以是eNB、RN等为UE提供接入服务的节点。
下面结合说明书附图对本发明实施例作进一步详细描述。
实施例一
在该实施例中,由第一网络侧设备为覆盖区域内的各个AP分配周期性的空口广播资源。
如图2所示,为本发明实施例一提供的信息交互方法流程图,包括以下步骤:
S201:第一网络侧设备为发送接入点(Access Point,AP)配置用于该发送AP向接收AP发送信息的周期性的空口广播资源。
这里,第一网络侧设备可以是集中控制节点、操作维护管理(Operation Administration and Maintenance,OAM)实体、或簇头AP。集中控制节点为管理预设区域范围内的各个AP的节点,可以是指一个独立的设备如宏基站,也可以是指实现集中控制功能的模块。簇头AP为从AP集合中选取的AP,每个AP集合内的任一AP都能够与该AP集合的簇头AP之间相互接收到对方以广播形式发送的空口信息。本发明实施例中的簇头AP可以是具有一定领导和控制功能的头领AP,该AP通常是在普通AP的基础上增加一定的额外条件,例如软硬件功能更强大,需要支持额外的控制功能,回程链路质量较好等;在密集接入节点部署的场景中,AP一般是分簇部署的,例如一个办公室,一栋公寓,或者是一个热点地区内的各个AP属于一个AP簇;一个AP簇内的AP都能够与簇头相互通信,进一步地,还可以进一步限定只有在任意两个AP之间都能够相互接收到彼此广播的信息的AP集合才作为一个AP簇。
当第一网络侧设备为簇头AP时,簇头AP可以基于第二网络侧设备(如OAM实体或集中控制节点)分配的空口广播资源池,为所在AP集合内的各个AP分配空口广播资源。
在具体实施中,每个AP既可以作为接收AP的发送AP,也可以作为发送AP的接收AP,也即任一AP都可以向其它AP广播信息,也可以接收其它AP广播的信息。这里,接收AP可以为其对应的发送AP的相邻AP,相应地,发送AP可以为其对应的接收AP的相邻AP,也即接收AP在其对应的发送AP的信号覆盖范围内,可以接收到该发送AP广播的空口信息。
在具体实施过程中,集中控制节点可以收集覆盖区域内网络的基本情况,例如AP位置和分布、AP覆盖下的UE分布及AP负荷情况、整体网络资源情况等,并收集一些AP上报的测量信息,结合这些信息进行综合考虑和决策之后,为每个AP分配各自的周期性的空口广播资源用于广播空口消息。
进一步地,在S201之前,发送AP可以首先向第一网络侧设备发送包含资源需求信息(比如需求的资源大小)的资源请求消息,在S201中,第一网络侧设备结合该资源请求消息为该发送AP配置周期性的空口广播资源,或可以进行周期性的空口广播资源的重配置,也即将发明实施例中的资源配置为半静态的配置。
S202:第一网络侧设备将配置的周期性的空口广播资源发送给所述发送AP,并将为所述发送AP配置的空口广播资源指示给所述发送AP的各个接收AP,以使每个接收AP在该空口广播资源上接收所述发送AP以广播形式发送的信息。
在具体实施过程中,第一网络侧设备可以为覆盖区域内的各个AP统一分配空口广播资源,并针对每个AP,将该AP的各个相邻AP的空口广播资源指示给该AP,用于该AP在各个相邻AP的空口广播资源的合集上接收相邻AP广播的空口消息。具体地,第一网络侧设备可以向发送AP指示该发送AP的每个接收AP(也即与该发送AP相邻的AP)各自的空口广播资源(比如包括每个接收AP的标识信息及每个接收AP的标识信息分别对应的空口广播资源),也可以直接将该发送AP的各个接收AP的空口广播资源的合集指示给该发送AP。
除上述方式外,还可以采用以下简化的方式:
第一网络侧设备也可以将能够分配给各个AP的所有空口广播资源作为总空口广播资源池发送给各个AP,每个AP在没有信息需要广播给其它AP时,在该总空口广播资源池上尝试接收其它AP广播的信息。
或者,第一网络侧设备也可以将当前分配了的各个AP的空口广播资源的合集发送给各个AP,每个AP在没有信息需要广播给其它AP时,在当前分配了的各个AP的空口广播资源的合集上尝试接收其它AP广播的信息。
或者,当第一网络侧设备为簇头AP时,簇头AP也可以将所在AP集合的空口广播资源的合集发送给该AP集合内的各个AP,该AP集合内的各个AP在没有信息需要广播给其它AP时,在该AP集合的空口广播资源的合集上尝试接收其它AP广播的信息。
S203:发送AP在接收的空口广播资源上,以广播形式向接收AP发送信息;接收AP在第一网络侧设备指示的发送AP的空口广播资源上,接收发送AP以广播形式发送的信息。
这里,发送AP在需要与相邻AP进行信息交互时,在集中控制节点分配的周期性的空口广播资源上,以广播形式发送空口信息。
可选地,接收AP接收的可以是该接收AP的每个发送AP各自的空口广播资源,此时接收AP在每个发送AP各自的空口广播资源上接收信息;接收AP接收的也可以是该接收 AP的各个发送AP的空口广播资源的合集,此时,接收AP直接在该空口广播资源的合集上接收信息。
实施例二
在该实施例中,发送AP采用竞争的方式自主确定周期性的空口广播资源。
如图3所示,为本发明实施例二提供的信息交互方法流程图,包括以下步骤:
S301:第二网络侧设备(比如操作维护管理实体(Operation Administration and Maintenance,OAM)或集中控制节点)配置空口广播资源池,并将配置的空口广播资源池发送给预设区域范围内的各个AP。
这里,该空口广播资源池也即资源集合,可以是静态配置的,也可以是半静态配置的(基于预设区域范围内网络环境的变化进行调整)。在具体实施中,所述空口广播资源池也可以是预设的,此时就无需该步骤中第二网络侧设备的配置过程了。若由第二网络侧设备配置,则第二网络侧设备将配置的空口广播资源池发送给预设区域范围内的各个AP,以使每个AP从中选择向其它AP发送信息的空口广播资源。
S302:发送AP从所述空口广播资源池中选择空口广播资源,并向接收AP发送指示所述发送AP选择的空口广播资源的资源抢占信令。
在具体实施过程中,若发送AP向对应的所有接收AP发送资源抢占信令,则可以采用广播的形式发送。具体地,第二网络侧设备可以配置广播资源抢占信令的抢占信令资源池,并发送给预设区域范围内的各个AP,发送AP从该抢占信令资源池中选择抢占信令资源,在选择的抢占信令资源上,以广播形式向接收AP发送资源抢占信令。
发送AP还可以只向簇头AP发送资源抢占信令,也即向簇头AP确认选择的空口广播资源是否可用;此时发送AP可以采用广播形式向簇头AP发送资源抢占信令(在资源抢占信令中指示接收方为簇头AP或默认接收方为簇头AP),发送AP也可以采用点对点的方式向簇头AP发送资源抢占信令。
S303:接收AP向发送AP发送针对所述资源抢占信令的反馈消息。
可选地,接收AP可以在确定所述资源抢占信令接收正确,且该资源抢占信令中指示的空口广播资源与该接收AP及该接收AP的其它发送AP的空口广播资源不存在冲突后,向所述发送AP反馈针对所述资源抢占信令的确认消息;和/或,接收AP可以在确定所述资源抢占信令接收错误,或者该资源抢占信令中指示的空口广播资源与该接收AP或该接收AP的其它发送AP的空口广播资源存在冲突后,向所述发送AP反馈针对所述资源抢占信令的非确认消息。
S304:发送AP基于接收AP针对所述资源抢占信令的反馈消息,判断是否成功抢占 选择的所述空口广播资源;若是,则进入S305,否则,返回S302。
在具体实施中,每个AP根据自身的需求及相邻AP的资源占用情况在所述空口广播资源池中选择合适的空口广播资源,并将指示选择的空口广播资源的资源抢占信令发送出去,如果接收到确认空口广播资源能够使用的反馈消息(比如确认ACK消息),或者如果没有接收到确认空口广播资源不能够使用的反馈消息(比如非确认NACK消息,这种方式默认不反馈的情况为确认空口广播资源能够使用),则可以认为成功占用选择的空口广播资源,在后续的时间里,使用该空口广播资源进行信息发送;如果需要重新配置,也可以重新选择空口广播资源,并重新发送资源抢占信令。相应地,AP在接收资源抢占信令后,如果接收正确,且资源抢占信令中指示的空口广播资源与自己的或已知的该AP的其它相邻AP的空口广播资源不冲突,则可以反馈ACK消息,否则可以反馈NACK消息,或者不进行反馈(这种方式默认不反馈的情况为确认空口广播资源不能够使用)。
可选地,在具体实施中,针对任一AP,该AP作为发送AP时,可以基于任一接收AP针对资源抢占信令的反馈消息,判断是否成功抢占选择的所述空口广播资源,此时发送AP可以采用广播形式发送资源抢占信令;
在这种方式下,第二网络侧设备(OAM实体或集中控制节点)可以预先为预设区域范围内的各个AP配置广播资源抢占信令的抢占信令资源池(也可以是预设的),并发送给预设区域范围内的各个AP;发送AP从该抢占信令资源池中选择抢占信令资源,在选择的抢占信令资源上,以广播形式向接收AP发送资源抢占信令;相应地,接收AP基于该抢占信令资源池,接收发送AP广播的资源抢占信令,并作出反馈。
可选地,还可以由簇头AP专门负责进行资源抢占信令的反馈,此时发送AP可以采用点对点的方式(有线X2口传输,或者复用RN与DeNB之间的空口传输过程)向簇头AP发送资源抢占信令(也即向簇头AP确认选择的空口广播资源是否可用)。发送AP也可以采用广播形式向簇头AP发送资源抢占信令,此时发送AP可以在广播的资源抢占信令中指示接收AP为簇头AP,或者默认由簇头AP进行反馈,其它AP接收到该资源抢占信令后不作处理。这里,由于簇头AP与本集合内其它AP都能通信,簇头AP还可以结合本集合内各AP的资源配置,为发送AP配置最优的空口广播资源,因此可以固定由簇头AP进行反馈,不仅可以减少其它AP的反馈信息发送量,还可以优化资源配置。详见下述实施例三的描述。
S305:发送AP在确认成功抢占选择的所述空口广播资源后,将选择的空口广播资源确定为向接收AP发送信息的周期性的空口广播资源。
S306:发送AP在确定的周期性的空口广播资源上,以广播形式向接收AP发送信息; 接收AP在所述空口广播资源池上,接收发送AP以广播形式发送的信息。
该步骤中,接收AP在整个空口广播资源池上,尝试对发送AP广播的信息进行接收并处理。
除S306的方式外,接收AP还可以在发送AP发送的资源抢占信令所指示的空口广播资源上接收信息。进一步地,接收AP还可以在确定发送AP能够使用该发送AP的资源抢占信令所指示的空口广播资源后,在该空口广播资源上接收发送AP以广播形式发送的信息。
实施例三
在该实施例中,发送AP基于空口广播资源池自主选择周期性的空口广播资源,并向簇头AP请求确认,在簇头AP确认后,在选择的空口广播资源作为自身周期性的空口广播资源。
如图4所示,为本发明实施例三提供的信息交互方法流程图,包括以下步骤:
S401:第二网络侧设备(比如操作维护管理实体(Operation Administration and Maintenance,OAM)或集中控制节点)配置空口广播资源池,并将配置的空口广播资源池发送给预设区域范围内的各个AP。
S402:发送AP从所述空口广播资源池中选择周期性的空口广播资源,并向簇头AP发送指示所述发送AP选择的空口广播资源的资源抢占信令。
这里,发送AP可以采用点对点的方式向簇头AP发送所述资源抢占信令,也可以采用广播形式向簇头AP发送所述资源抢占信令,当采用广播形式发送所述资源抢占信令时,可参见实施例二介绍的关于从抢占信令资源池中选择抢占信令资源的内容。
S403:簇头AP向发送AP发送针对所述资源抢占信令的反馈消息。
该实施例中,每个AP根据自身的需求以及相邻AP的资源占用情况在所述空口广播资源池中选择合适的空口广播资源,并将选择的空口广播资源指示给簇头AP进行确认,如果簇头AP确认该空口广播资源可以使用(比如簇头AP反馈了ACK信息),则可以认为将该空口广播资源占用成功,在后续的时间里,使用该空口广播资源进行信息发送,如果簇头AP确认该空口广播资源不可以使用(比如簇头AP反馈了NACK信息),则需要重新选择空口广播资源,并重新指示给簇头AP进行确认。
S404:发送AP基于簇头AP针对所述资源抢占信令的反馈消息,判断是否成功抢占选择的所述空口广播资源;若是,则进入S405,否则,返回S402。
S405:发送AP在确认成功抢占选择的所述空口广播资源后,将选择的空口广播资源确定为向接收AP发送信息的周期性的空口广播资源。
S406:发送AP在确定的周期性的空口广播资源上,以广播形式向接收AP发送信息;接收AP在所述空口广播资源池上,接收发送AP以广播形式发送的信息。
上述实施例一至三是以采用半静态的资源配置方式进行实施说明,一次配置的空口广播资源可以在后续多次信息发送中被周期性使用,在需要时可以进行资源重配置。
下面列举一个具体例子说明上述半静态的资源配置方式的应用:
假设在一片区域中有10个AP,这10个AP分别通过上述实施例一至三中的任一种方式获得了自己的空口广播资源,分别为:AP1:资源1,重复周期T1;AP2:资源2,重复周期T2;……;AP10:资源10,重复周期T10。每个AP获知这些资源的合集为Set A,则每个AP各自根据需要在自己的空口广播资源上进行信息发送,每个AP在Set A中非自己的空口广播资源上,对其它AP进行信息接收及处理。采用本发明实施例,每个AP可以向相邻AP广播自己的信息,同时每个AP也可以从相邻AP接收信息,从而可以调整自己的状态,达到规避干扰、协作协调、提高传输效率的目的。
需要说明的是,在上述资源分配过程中,每个AP的资源并不一定是完全独占的,当超过一定的通信范围之后,相同的资源可以再次被复用,只需要保证复用资源的两个AP不具有相同的相邻AP即可。
相比上述实施例一至三的半静态配置方式,以下实施例四至五介绍的是资源动态配置的过程。
实施例四
在该实施例四中,AP在需要以广播形式向相邻AP发送信息时,向第一网络侧设备发送资源请求消息,请求获取本次发送信息的空口广播资源。
如图5所示,为本发明实施例四提供的信息交互方法流程图,包括以下步骤:
S501:发送AP在需要向接收AP发送信息时,向第一网络侧设备发送资源请求消息,其中包含资源需求信息。
这里的资源需求信息可以包含资源大小等对资源的需求信息。与上述实施例一至三不同,该实施例中,发送AP每次需要向接收AP发送信息时,都需要请求空口广播资源。
S502:第一网络侧设备根据该资源请求消息中包含的资源需求信息,为该发送AP配置用于该发送AP向接收AP发送信息的空口广播资源。
在具体实施过程中,第一网络侧设备可以根据每个AP的资源需求信息,以及整体的资源分布和干扰情况等,为预设区域范围内的每个AP配置空口广播资源。
S503:第一网络侧设备将配置的空口广播资源发送给所述发送AP,并将为所述发送AP配置的空口广播资源指示给所述发送AP的各个接收AP,以使每个接收AP在该空口 广播资源上接收所述发送AP以广播形式发送的信息。
该步骤中,第一网络侧设备针对每个AP,可以将该AP的各个相邻AP的空口广播资源指示给该AP,用于该AP在各个相邻AP的空口广播资源上进行信息接收。具体地,第一网络侧设备可以向接收AP指示该接收AP的每个发送AP(接收AP的相邻AP)各自的空口广播资源(比如包括每个发送AP的标识信息及每个发送AP的标识信息分别对应的空口广播资源),也可以直接将该接收AP的各个发送AP的空口广播资源的合集指示给该接收AP。
这里,第一网络侧设备仅将AP的空口广播资源指示给与该AP相邻的一些AP,用于这些AP作接收准备,而对于离该AP较远的AP来说(指超过该AP的接收和覆盖范围),无法接收该AP的信息,因此不需要知道该AP的空口广播资源,也可以避免进行无谓的尝试接收。更进一步地,对于一些较远的AP,可以认为与该AP相关的资源处于空闲状态,仍旧可以用于其它有用数据的传输。对于第一网络侧设备,需要有较优化的算法判断每个AP的接收和覆盖范围,比如可以基于位置信息、测量信息,基于上报信息等来判断,一般来说,这些信息属于较静态的信息,可以进行数据库信息存储,并根据情况更新。
除了上述S503将为发送AP配置的空口广播资源指示给该发送AP的各个接收AP(与该发送AP相邻的AP)的优化方式外,还可以采用下述简化的方式,以减少第一网络侧设备配置发送信息的复杂度:
第一网络侧设备将能够分配给预设区域范围内的各个AP的所有空口广播资源作为总空口广播资源池发送给各个AP,每个AP在没有信息需要广播给其它AP时,在该总空口广播资源池上尝试接收其它AP广播的信息;
或者,第一网络侧设备也可以将当前分配了的各个AP的空口广播资源的合集发送给各个AP,每个AP在没有信息需要广播给其它AP时,在当前分配了的各个AP的空口广播资源的合集上尝试接收其它AP广播的信息。
或者,当第一网络侧设备为簇头AP时,簇头AP也可以将所在AP集合的空口广播资源的合集发送给该AP集合内的各个AP,该AP集合内的各个AP在没有信息需要广播给其它AP时,在该AP集合的空口广播资源的合集上尝试接收其它AP广播的信息。
S504:发送AP在接收的空口广播资源上,以广播形式向接收AP发送信息;接收AP在第一网络侧设备指示的发送AP的空口广播资源上,接收发送AP以广播形式发送的信息。
该步骤可参见上述S503之后内容的描述。
在上述实施例四中,第一网络侧设备可以是OAM实体或集中控制节点,还可以是簇 头AP,如果是簇头AP,则该簇头AP基于第二网络侧设备(OAM实体或集中控制节点)配置的空口广播资源池为所在AP集合内的每个AP分配空口广播资源,簇头AP可以将为每个AP分配的空口广播资源分别通知给对应的AP,也可以广播通知,在广播通知时,需要在广播通知的通知消息中指示分别分配给每个AP的空口广播资源。
实施例五
在该实施例中,各AP之间随机竞争当前发送信息所需的空口广播资源。
如图6所示,为本发明实施例五提供的信息交互方法流程图,包括以下步骤:
S601:第二网络侧设备(OAM或集中控制节点)配置空口广播资源池,并将配置的空口广播资源池发送给预设区域范围内的各个AP。
这里,该空口广播资源池也即资源集合,可以是静态配置或半静态配置的。在具体实施中,所述空口广播资源池也可以是预设的,此时就无需该步骤中第二网络侧设备的配置过程了。
S602:发送AP在需要向接收AP发送信息时,从所述空口广播资源池中选择空口广播资源,并在选择的空口广播资源上,以广播形式向接收AP发送信息。
在具体实施过程中,可以规定空口广播资源池的使用规则,AP在需要发送信息时,可以按照该规则,采取随机避免的方式选择空口广播资源进行信息发送。空口广播资源池的使用规则可以包括以下中的一种或多种:
规定每个AP抢占的资源粒度;例如可以设置允许的资源大小列表,简单地,可以只允许一种资源大小;灵活一些地,还可以允许多种大小,为了更好的对齐资源,减少因资源冲突造成无法解码,可以规定各种资源大小(如size1、size2、size3)之间的关系,例如size2=2size1=1/2size3等;或者,对资源池进行编号;可以以最小的资源大小为粒度,对资源池进行顺序编号,例如在某个时隙上,分配了一定的频带资源,将该频带资源按照最小资源大小划分,分为资源1、资源2、资源3,UE只可以选取其中N块资源,N≥1;
规定编码格式;例如只支持一种或者几种编码格式,对接收端来说,如果仅规定了一种编码格式,则解码较易,如果支持几种,则需要进行尝试解码;
S603:接收AP在所述空口广播资源池上,接收发送AP以广播形式发送的信息,并向发送AP发送反馈消息。
可选地,接收AP在确定接收的信息正确后,向接收到的信息所对应的发送AP反馈确认消息;和/或,接收AP在确定接收的信息错误后,向接收到的信息所对应的发送AP反馈非确认消息。
在具体实施中,可以给每块资源规定对应的反馈位置,该反馈位置可以用于反馈非确 认(NACK)消息或确认(ACK)消息,当接收AP正常接收到信息时无需发送反馈消息或发送ACK消息,而一旦发生了碰撞,则反馈NACK信息;发送AP在接收到NACK后,则考虑进行信息重发。
可选地,簇头AP作为接收AP时,可以由簇头AP专门负责进行针对该簇头AP所在AP集合内的发送AP广播的信息的反馈。比如,发送AP在空口广播资源池中随机挑选了一块资源发送自己的空口信息,簇头AP在正确接收到该信息后,反馈ACK信息,若接收错误,则反馈NACK信息。
S604:发送AP基于接收AP针对该发送AP在选择的空口广播资源上发送的信息的反馈消息,判断该信息是否被成功发送;若否,则进入S605。
可选地,发送AP可以基于任一接收AP针对所述发送AP发送的信息的反馈消息,判断该信息是否被成功发送;比如若接收到NACK消息,则认为信息未被成功发送;或者,
当由簇头AP负责进行反馈时,发送AP基于簇头AP针对所述发送AP发送的信息的反馈消息,判断该信息是否被成功发送。
S605:发送AP重新选择空口广播资源,并在重新选择的空口广播资源上,进行信息重发,返回S603。
这里,若发送AP发送的为非实时信息,则在确定信息发送失败后,可以重新选择其它空口广播资源进行信息重发。若发送AP发送的为实时信息,则在信息发送失败后,可以直接放弃,也即忽略碰撞,这是因为当AP发送的信息是实时性信息(比如语音)时,一旦发生碰撞,重发也没有太大意义,因为时效性已经过了,此时只能等待该AP下次发送新的信息,或者可以将提前触发新信息的发送。
实施例六
在上述实施例五中,直接以抢占的方式在空口广播资源池中选择空口广播资源发送信息,这种方式时延较小,但一旦发生信息的冲突碰撞,则损失较大。该实施例六提供另一种抢占资源的方式,发送AP先发送资源抢占信令,待确认无误之后,再在相应的资源上广播当前的空口信息。
如图7所示,为本发明实施例六提供的信息交互方法流程图,包括以下步骤:
S701:第二网络侧设备(比如OAM或集中控制节点)配置抢占信令资源池和空口广播资源池,并将配置的抢占信令资源池和空口广播资源池发送给预设区域范围内的各个AP。
S702:发送AP在需要向接收AP发送信息时,在所述空口广播资源池中选择空口广播资源,在抢占信令资源池中选择抢占信令资源,在选择的抢占信令资源上向接收AP发 送指示所述发送AP选择的空口广播资源的资源抢占信令。
本实施例中,发送AP采用广播形式发送资源抢占信令。具体地,第二网络侧设备配置抢占信令资源池,发送AP从该抢占信令资源池中选择抢占信令资源,在选择的抢占信令资源上,以广播形式向接收AP发送资源抢占信令。
S703:接收AP向发送AP发送针对所述资源抢占信令的反馈消息。
可选地,发送AP广播的资源抢占信令可以是只针对簇头AP的,此时发送AP可以在该资源抢占信令中指示接收AP为簇头AP,也可以不指示,此时默认由簇头AP针对该资源抢占信令进行反馈,其它接收AP不作处理。
S704:发送AP基于接收AP针对所述资源抢占信令的反馈消息,判断是否成功抢占选择的所述空口广播资源;若是,则进入S705,否则,返回S702(若为实时信息则放弃)。
该实施例中,发送AP在发送资源抢占信令后,如果接收到确认空口广播资源能够使用的反馈消息(比如确认ACK消息),则可以认为成功占用选择的空口广播资源,则使用选择的该空口广播资源进行本次信息发送,否则重新发送资源抢占信令。
可选地,发送AP在需要发送信息时,可以在向对应的各个接收AP发送资源抢占信令后,不等待ACK反馈,而是直接使用选择的空口广播资源进行信息发送。这种方式也即忽略碰撞,这种方式一般应用在需要进行实时信息的发送的情况,由于接收AP针对资源抢占信令的反馈时延较长,与实时信息的时效性产生冲突,因此只能忽略碰撞,若发生碰撞,则只能期待下次更新发生或提前触发下次信息发送。
S705:发送AP在确认成功抢占选择的所述空口广播资源后,将选择的空口广播资源确定为本次向接收AP发送信息的空口广播资源。
S706:发送AP在确定的空口广播资源上,以广播形式向接收AP发送信息;接收AP在所述空口广播资源池上,接收发送AP以广播形式发送的信息。
基于同一发明构思,本发明实施例中还提供了一种与信息交互方法对应的信息交互装置及设备,由于该装置及设备解决问题的原理与本发明实施例信息交互方法相似,因此该装置及设备的实施可以参见方法的实施,重复之处不再赘述。
