Abstract

Description

建立承载的方法、装置及系统 技术领域
本发明涉及移动通信系统,尤其涉及一种建立承载的方法、装置及系统。
背景技术
在长期演进(Long Term Evolution,LTE)网络中,为了节省无线资源和减少用户设备(user equipment,UE)耗电,当UE在一段时间(例如:30秒)内未与网络进行业务交互(即信令或用户面数据传输)时,网络会释放在空口一侧与UE之间的信令连接和用户面承载;当UE需要发送或者接收用户面数据时,UE会首先恢复与网络的信令连接,通过该信令连接恢复用户面承载,然后通过所恢复的用户面承载发送或者接收用户面数据。
因此,LTE网络中的用户面承载更适合于频繁的大量数据传输的场景。对于非频繁小数据业务,例如:M2M(Machine-to-Machine)业务,数据量小,能够容忍较低的数据传输速率,对时延不敏感,通常采用控制面承载传输,即采用非接入层(non-access stratum,NAS)消息传输,不但能够避免频繁建立用户面承载,减少信令开销,还能降低运营商成本。
但是,由于不同时段客户需求不同,UE接收或发送的数据量也不断变化。以电表业务为例:正常情况下,电表周期性上传一些小数据;但某一时段,客户需要对电表进行软件升级,需要传输大量数据。如何合理地为UE建立承载以高效传输大幅波动的数据,成为迫切需要解决的问题。

具体实施方式
下面将结合本发明实施例中的附图,对本发明实施例中的技术方案进行清楚、完整地描述,显然,所描述的实施例仅是本发明一部分实施例,而不是全部的实施例。基于本发明中的实施例,本领域普通技术人员在没有做出创造性劳动前提下所获得的所有其他实施例,都属于本发明保护的范围。
图1a是一种LTE系统的结构示意图,LTE系统由演进型通用陆地无线接入网(Evolved UMTS Terrestrial Radio Access Network,E-UTRAN)和演进分组核心网(Evolved Packet Core,EPC)组成。其中,E-UTRAN是由多个eNodeB001组成的网络。EPC包括负责信令处理的移动管理实体(Mobility Management Entity,MME)002和负责数据处理的服务网关(Serving Gateway,SGW)003。E-UTRAN中的eNodeB001通过用户面接口与EPC中的SGW003连接,通过控制面接口与EPC中的MME002连接,并通过LTE-Uu接口与UE004连接,EPC中的MME002通过S11接口与SGW003连接。其中,用户面接口也称为S1-U,控制面接口也称为S1-MME。
需要说明的是,在本发明各实施例中,用户面承载具体可以包括LTE-Uu接口的数据无线承载(data radio bear,DRB),以及S1-U的S1用户面承载。控制面承载具体可以是UE和MME之间的NAS消息,而NAS消息可以通过LTE-Uu接口的信令无线承载(signaling radio bearer,SRB)和S1-MME接口的S1控制面信令承载来传输。
进一步地,上述用户面承载与控制面承载之间的区别可以以UE发送的上行数据传输途径为例,说明如下:
当UE004采用控制面承载传输发送数据时,UE004通过LTE-Uu口的SRB以及S1-MME接口的S1控制面信令承载将携带有该数据的NAS消息发送给MME002,MME002通过S11接口的S11用户面承载将接收到的数据发送给 SGW003,这种采用控制面承载传输UE的待发送数据的方式可以称之为控制面传输方式。
当UE004采用用户面承载传输数据时,UE004通过LTE-Uu口的DRB将数据发送给eNodeB001,eNodeB001通过S1-U接口的S1用户面承载将接收到的数据发送给SGW003,这种采用用户面承载传输UE的待发送数据的方式可以称之为用户面传输方式。
上述说明对本发明没有限制作用,仅是用来示例性说明采用上述两种不同类型承载传输数据的路径不同。
如图1b所示,本发明实施例提供了一种建立承载的方法,对于UE处于空闲态或连接态均适用,具体如下:
步骤101,MME接收指示信息,该指示信息用于指示为UE建立的承载类型。
其中,上述承载类型具体可以包括用户面承载或控制面承载,该用户面承载具体可以包括DRB(UE与基站之间的承载),以及S1用户面承载(基站与SGW之间的承载);该控制面承载具体可以是UE和MME之间的NAS消息,而NAS消息可以通过SRB(UE与基站之间的承载)和S1控制面信令承载(基站与MME之间的承载)来传输,可以参见图1a所示的相关描述,属于现有技术,不再赘述。
需要说明的是,上述指示信息所指示的承载类型具体可以采用显示的方式,也可以采用隐式的方式,举例说明如下:
当采用显示的方式时,可以使用指示比特的设置值来显示指示承载类型为用户面承载或控制面承载,例如,当指示比特的设置值为1时,指示为用户面承载,当指示比特的设置值为0时,指示控制面承载;
当采用隐式的方式时,假设该指示信息用来指示该UE的待发送数据的状态指示信息,例如,当指示信息的设置值为1时,表明该UE的待发送数据的数据量大于预设的数据量门限,即为大数据,此时,为能够给该UE提供更好的服务质量,MME为UE建立用户面承载以传输该UE的待发送数据;当指示信息的设 置值为0时,表明该UE的待发送数据的数据量小于预设的数据量门限,且该UE的待发送数据的发送频率小于预设的频率门限,即非频繁小数据,此时,为了避免浪费大量的信令资源和UE的电量,MME为UE建立控制面承载来传输该UE的待发送数据。
其中,上述指示信息可以携带在NAS消息中发送给上述MME。
可选地,步骤101具体可以采用如下两种实现方式:
方式一、接收上述UE发送的指示信息。
其中,该指示信息具体可以携带在服务请求(service request)消息中。
方式二、接收网关设备发送的指示信息。
其中,上述网关设备可以为上述UE的SGW或分组数据网网关(packet gateway,PGW),本发明不予限制。
进一步地,当上述网关设备为上述UE的SGW时,上述指示信息可以携带在GPRS隧道协议(GPRS Tunneling Protocol,GTP)消息中,例如,下行数据通知(Downlink Data Notification,DDN)消息。
步骤102,MME根据该指示信息,为该UE建立承载。
具体地,步骤102可以包括如下102a和102b中的至少一个步骤。
102a,若上述指示信息所指示的承载类型为用户面承载,则上述MME为该UE建立用户面承载。
其中,步骤102a中MME为该UE建立用户面承载具体可以包括:
MME将该UE的基站的地址以及该基站的隧道端点标识(Tunnel Endpoint ID,TEID)发送给SGW;
MME将SGW的地址和TEID发送给该UE的基站。
其中,上述UE的基站具体可以是为该UE提供服务的基站,上述SGW具体可以是为UE提供服务的服务网关。
102b,若上述指示信息所指示的承载类型为控制面承载,则上述MME为该UE建立控制面承载。
其中,步骤102b中MME为该UE建立控制面承载具体可以包括:
该MME将该MME的地址和TEID发送给该UE的SGW;
该MME接收该UE的SGW的地址和TEID。
进一步地,当UE处于空闲状态时,步骤102b中MME为该UE建立控制面承载还包括:
该MME发送寻呼消息给该UE;
接收该UE发送的NAS响应消息,建立SRB。
本发明实施例提供的建立承载的方法,通过接收用于指示为UE建立的承载类型的指示信息,并根据指示信息为UE建立不同类型的承载,使得MME能够根据需求实时地调整承载类型,为UE建立不同类型的承载,进而实现了高效传输大幅波动数据,提升用户感受的同时,降低了网络以及用户设备的损耗。
可选地,在上述实施例的第一种实现场景下,在上述步骤102a中MME为该UE建立用户面承载之前,还包括:
若MME与该UE的SGW之间采用控制面传输方式传输数据,则MME发送请求消息给该UE的SGW,该请求消息用于请求该SGW的地址和TEID;
MME接收该SGW发送的该SGW的地址和TEID;或者,
MME接收该SGW发送的该SGW的地址和TEID。
其中,上述SGW的地址和TEID具体可以携带在GTP消息中发送给MME,例如,DDN消息。
需要说明的是,当步骤101中采用上述方式二的实现方式时,网关设备可以将指示信息和上述SGW的地址以及TEID携带在同一GTP消息中发送给MME,此处不予限制。
可选地,在上述实施例的第二种实现场景下,在上述步骤102a之后,还包括:
MME释放该MME与该UE的SGW之间的用户面承载。
具体地,由于SGW通过S1用户面承载将UE的下行数据发送给基站,进而 发送给该UE,MME与SGW之间的S11用户面承载不再用于发送UE的下行数据,因此MME可以释放S11用户面承载,以节省资源。
可选地,在上述实施例的第三种实现场景下,在上述步骤102b中MME为该UE建立控制面承载之后,还包括:
MME通知该UE采用控制面传输方式传输数据。
具体地,MME可以通过寻呼消息或跟踪区更新(Tracking Area Update,TAU)接受消息来通知UE采用控制面传输方式传输数据,此处不予限制。
上述通知UE采用控制面传输方法传输数据,能够避免UE上行数据的重传,提升用户体验。
可选地,在上述实施例的第四种实现场景下,在步骤102b MME为该UE建立控制面承载之后,还包括:
MME触发释放数据无线承载和S1用户面承载。
上述对数据无线承载和S1用户面承载的释放,能够避免资源浪费,提高无线网络系统的运行效率。
可选地,在上述实施例的第五种实现场景下,在步骤102之后,还包括:
步骤103,MME发送传输方式指示信息给PGW,该传输方式指示信息用于指示所述UE的数据传输方式为控制面传输方式或用户面传输方式。
采用上述步骤103,将传输方式指示信息发送给PGW,以便PGW对不同传输方式采用不同的计费方法。
如图2所示,本发明实施例提供了一种建立承载的方法,该方法由MME执行,具体如下:
步骤201,监控UE的数据传输状态,该UE的数据传输状态包括该UE的数据量和该UE的数据包发送频率中至少一种。
其中,UE的数据量可以是一段时间内UE的上行数据总量,或者UE的下行数据总量,也可以是一段时间内UE的上行数据总量和下行数据总量之和;UE 的数据包发送频率可以是UE的上行数据包发送频率,或者UE的下行数据包发送频率,显然,还可以是UE的上下行数据包发送频率,本发明不做任何限制。此外,UE的数据包发送频率可以替换为数据包发送间隔,即两个数据包发送的时间间隔,由于频率和间隔含义属于现有技术,不再赘述。
在步骤201之后,可以执行步骤202或203,不予限制。
步骤202,当该UE的数据传输状态满足第一预设条件时,为该UE建立用户面承载。
其中,第一预设条件可以预先设置在MME内部,也可以通过外部接口配置给MME。此外,第一预设条件可以考虑数据传输过程中质量,频率,数据量的大小或数据包发送间隔等,具体可以举例说明如下:
若该UE的数据传输状态包括该UE的数据量,则该第一预设条件为该UE的数据量大于预设的数据量门限;或者,
若该UE的数据传输状态包括该UE的数据包发送频率,则该第一预设条件为该UE的数据包发送频率大于预设的频率门限;或者,
若该UE的数据传输状态包括该UE的数据量和该UE的数据包发送频率,则该第一预设条件为该UE的数据包发送频率大于预设的频率门限,或该UE的数据量大于预设的数据量门限。
步骤203,当所述UE的数据传输状态满足第二预设条件时,为该UE建立控制面承载。
其中,第二预设条件可以预先设置在MME内部,也可以通过外部接口配置给MME。此外,第二预设条件可以考虑数据传输过程中质量,频率,数据量的大小或数据包发送间隔等,具体可以举例说明如下:
若该UE的数据传输状态包括该UE的数据量,则该第二预设条件为该UE的数据量小于预设的数据量门限;或者,
若该UE的数据传输状态包括该UE的数据包发送频率,则该第二预设条件为该UE的数据包发送频率小于预设的频率门限;或者,
若该UE的数据传输状态包括该UE的数据量和该UE的数据包发送频率,则该第二预设条件为该UE的数据包发送频率小于预设的频率门限,且该UE的数据量小于预设的数据量门限。
需要说明的是,上述步骤202、203中的用户面承载和控制面承载的描述具体可以参见图1b所示实施例,不再赘述。

可选地,在上述实施例的第二种实施场景下,在步骤202之后,还包括:

具体地,由于SGW通过S1用户面承载将UE的下行数据发送给基站,进而发送给该UE,MME与SGW之间的S11用户面承载不再用于发送UE的下行数据,因此MME可以释放S11用户面承载,以节省资源。
可选地,在上述实施例的第三种实施场景下,在步骤202之后还包括:
