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。
如图1所示,其为核心网侧实施本发明实施例提供的第一种信息传输方法的实施流程示意图,可以包括以下步骤:
S11、确定允许无线接入网络设备对UE当前正在使用的业务进行业务优化时,向无线接入网络设备发送允许进行业务优化的指示信息。
具体实施时,核心网设备可以在UE与业务服务器处于连接状态下,确定允许无线接入网络设备对UE当前正在使用的业务进行业务优化,本发明实施例中涉及的UE与业务服务器处于连接状态是指UE可以通过无线接入网络设备(例如基站)以及核心网与业务服务器传输数据。
具体实施时,如果核心网设备确定不允许无线接入网络设备对UE当前正在使用的业务进行业务优化时,可以向无线接入网络设备发送不允许业务优化的指示信息,也可以不进行指示,按照相关技术的业务流程执行即可,本发明实施例对此不进行限定。为了便于描述,以下以核心网设备确定不允许无线接入网络设备对UE当前正在使用的业务进行业务优化时,向无线接入网络设备发送不允许业务优化的指示信息为例进行说明。
图1所示的流程为核心网主动发起是否允许对UE当前使用业务进行优化的判断,在一些实施例中,核心网通过对UE与业务服务器之间传输的数
据包进行解析获得UE当前正在使用业务的业务信息,根据获得的业务信息和预先存储的业务控制策略确定允许无线接入网络设备对UE当前正在使用的业务进行业务优化。
基于此,在执行步骤S11之前,该方法还可以包括以下步骤:
S11’、解析UE与业务服务器之间传输的数据包,获得UE当前正在使用业务的业务信息。
具体实施时,核心网设备可以利用深度报文检测(DPI)方法对UE与业务服务器之间传输的数据包进行解析,以获得UE当前正在使用业务的业务信息。
S11”、根据获得的业务信息和预先存储的业务控制策略确定允许无线接入网络设备对UE当前正在使用的业务进行业务优化。
核心网设备根据获得的业务信息和预先存储的业务控制策略确定允许无线接入网络设备对UE当前正在使用的业务进行业务优化。具体地,核心网中的移动性管理实体(MME),服务网关(S-GW)或者分组网关(P-GW)等)向策略与计费规则功能实体(PCRF,Policy and Charging Rules Function)发送策略请求,其中携带有UE标识和获得的业务信息,PCRF根据预先存储的控制策略确定是否允许针对该业务当前正在进行的业务进行优化,并向MME,S-GW或者P-GW返回允许进行业务优化或者不允许进行优化的策略响应,MME,S-GW或者P-GW根据PCRF返回的策略响应向无线接入网络设备返回允许进行业务优化或者不允许进行业务优化的指示信息。
作为本发明实施例的另外一种实施方式,核心网设备还可以在无线接入网络设备的触发下发起是否允许对UE当前使用业务进行优化的判断。
基于此,核心网侧实施的信息传输方法,在执行步骤S11之前,还可以包括以下步骤:接收所述无线接入网络设备发送的业务优化许可请求,在接收到的业务优化许可请求中携带有UE当前正在使用业务的业务信息,
核心网根据获得的业务信息和预先存储的业务控制策略确定允许无线接入网络设备对UE当前正在使用的业务进行业务优化。具体地,核心网中的MME,S-GW或者P-GW等)向PCRF发送策略请求,其中携带有UE标识和获得的业务信息,PCRF根据预先存储的控制策略确定是否允许针对该业务当前正在进行的业务进行优化,并向MME,S-GW或者P-GW返回允许进行业务优化或者不允许进行优化的策略响应,MME,S-GW或者P-GW根据PCRF返回的策略响应向无线接入网络设备返回允许进行业务优化或者不允许进行业务优化的指示信息。
具体地,如果PCRF返回允许进行业务优化的策略,则MME,S-GW或者P-GW向无线接入网络设备返回允许进行业务优化的指示信息,如果PCRF返回不允许进行业务优化的策略,则MME,S-GW或者P-GW向无线接入网络设备返回不允许进行业务优化的指示信息。
在上述过程中,如果PCRF向MME,S-GW或者P-GW返回新的计费等策略,MME,S-GW或者P-GW还需要针对UE当前使用业务更新计费策略。
其中,无线接入网络设备对UE当前正在进行的业务进行优化包括两个方面的优化,一种是通过核心网向业务服务器发送无线优化信息,使得业务服务器可以根据无线优化信息对与UE之间的数据传输进行优化,另外一种是本地业务优化,即在无线接入网络设备侧判断出UE当前正在进行的业务为本地业务时,不再将业务数据包通过核心网发送给业务服务器,而是由无线接入网络设备直接转发给本地部署的服务器。以下对这两种实施方式分别进行介绍。
实施方式一、无线接入网络设备针对UE当前正在使用的业务向所述业务服务器发送无线优化信息。
这种实施方式下,步骤S11中可以为确定允许无线接入网络设备针对
UE当前正在使用的业务向业务服务器发送无线优化信息。相应地,如果为无线接入网络设备触发核心网设备执行步骤S11,则接收无线接入网络设备发送的业务优化许可请求可以为接收无线接入网络设备发送的、携带有无线优化信息的用户面数据报文。
在一些实施例中,无线接入网络设备可以在接收到所述UE发送的业务优化请求后向核心网网络设备发送所述用户面数据报文。实际应用时,UE可以在检测到满足预设的触发条件时,向无线接入网络设备发送业务优化请求,其中,所述触发条件可以包括以下至少一个条件:
(1)在UE发起初始连接时,如果应用服务器为TCP服务器,则UE可以在TCP慢启动阶段向无线接入网络设备发送业务优化请求,即UE在与TCP三次握手过程中向无线接入网络设备发送业务优化请求;如果应用服务器为视频服务器,则UE可以在与视频服务器建立初始连接过程中向无线接入网络设备发送业务优化请求。
(2)UE检测到数据传输性能下降。例如,UE检测到接收到重复的确认数据包(ACK)次数超过预设阈值。
(3)UE本地业务缓存低于预设阈值,例如,UE检测到本地正在播放的视频播放停顿。
(4)UE检测到业务质量指标低于预设质量指标,例如,UE检测大本地正在播放的视频质量的质量参数低于预设的质量参数值,或者不满足预设的质量参数值等等,本发明实施例中不再一一列举。
以第四代(4G)移动通信系统为例,携带有无线优化信息的用户面数据报文可以包括GTP-U报文,其中,无线优化信息可以封装于GTP-U报文的扩展头中。即无线接入网络设备可以利用向核心网设备发送的GTP-U报文的扩展头携带无线优化信息,如果核心网设备确定允许接入网设备发送无线优化信息,则需获得无线优化信息,并将获得的无线优化信息封装到
数据载荷中发送给业务服务器。例如,核心网设备在接收到的GTP-U报文后,通过解析GTP-U报文获得需发送的无线优化信息,并将获得的GTP-U报文封装到数据载荷(payload)中传输给业务服务器。而如果核心网设备确定不允许无线接入网络设备发送无线优化信息,则可以将无线接入网络设备针对UE当前使用业务发送的数据包直接透传给业务服务器。
实施方式二、无线接入网络设备针对UE当前正在使用的业务进行本地缓存或者本地路由优化处理。
这种实施方式下,步骤S11可以为确定允许无线接入网络设备对所述UE当前正在使用的业务进行本地业务路由或者本地缓存业务分流。
相应地,如果为无线接入网络设备触发核心网设备执行步骤S11,则接收无线接入网络设备发送的业务优化许可请求可以为接收无线接入网络设备针对UE当前正在使用的业务发送的本地业务路由请求或者本地缓存业务分流请求,其中可以携带有UE标识和UE当前正在使用业务的业务信息,核心网设备如果确定允许进行本地业务优化处理,则向无线接入网络设备返回允许业务优化的指示信息,否则,向无线接入网络设备返回不允许业务优化的指示信息。无线接入网络设备根据接收到的指示信息,如果为允许业务优化的指示信息,则在接收到UE发送的业务数据包后,将接收到的业务数据包发送给本地业务服务器或者本地缓存服务器,而不再发送给核心网设备进行处理。

2)UE检测到数据传输性能下降。例如,UE检测到接收到重复的ACK次数超过预设阈值。
(3)UE本地业务缓存低于预设阈值,例如,UE检测到本地正在播放的视频播放停顿。
(4)UE检测到业务质量指标低于预设质量指标,例如,UE检测大本地正在播放的视频质量的质量参数低于预设的质量参数值,或者不满足预设的质量参数值等等,本发明实施例中不再一一列举。
