Description

一种建立无线承载的方法及网络设备 技术领域
本发明涉及通信领域,尤其涉及一种建立无线承载的方法及网络设备。
背景技术
自适应多码率(Adaptive Multi-Rate,简称AMR)是通信中采用的语音编解码方式,并具体分为自适应多码率窄带编解码(Adaptive Multi-Rate Narrowband,简称AMR-NB)和自适应多码率宽带编解码(Adaptive Multi-Rate Wideband,简称AMR-WB)。
其中,AMR-NB通过8KHz的语音采样频率产生频带宽度为300HZ-3400HZ的语音信号;而AMR-WB通过16KHZ的采样频率产生频带宽度为50HZ-7KHz的语音信号。50Hz-300HZ低频部分,提高了话音的自然度和临场感,3.4KHz-7KHz高频部分增加了发声的可懂度和摩擦音辨析度,因此,相比于AMR-NB,AMR-WB能够为用户提供高清语音。
为了提供更好的语音业务体验,越来越多的终端支持AMR-WB技术,移动通信运营商也在逐步部署基于AMR-WB技术的高清语音,因此,在现网中,存在并不是所有设备都可提供AMR-WB语音业务的现象。
在实现语音业务的过程中,要求端到端链路中的所有逻辑功能实体(例如核心网、接入网以及终端)都可提供AMR-WB语音业务,才能建立AMR-WB无线承载以提供高质量的语音业务,因此语音业务的质量取决于系统中语音业务编解码能力最低的设备;当通信双方(主/被叫终端)中只有一端的终端提供AMR-WB语音业务,其他设备仅提供AMR-NB语音业务,受业务能力的限制,只能为终端之间建立AMR-NB语音业务的无线承载,通信双方均采用AMR-NB实现低质量的语音业务,使用具备AMR-WB能力终端的用户无法体 验高清语音,导致终端的用户体验与终端能力不一致,用户体验度低。

需要说明的是,在S102的执行过程中,当无线接入网设备A接收到终端A发送的呼叫建立信令,则终端A和无线接入网A之间建立了信令面无线承载;当核心网设备接收到无线接入网设备A转发的终端A发送的呼叫建立信令时,则终端A和核心网之间建立了信令面陆地承载。
其中,终端B的标识可以为终端B的移动用户综合业务数字网(Mobile Subscriber Integrated Service Digital Network,简称MS ISDN)号码。
当然,终端的标识也可以为其他信息,只要能在网络中唯一识别该终端即可,对此并不进行具体限定。
S103、核心网设备根据终端B的标识寻呼终端B。
需要说明的是,核心网设备对于终端B的寻呼过程,可以根据实际需求实现,对此不进行具体限定,只要能寻呼到终端B即可。
S104、核心网设备通过无线接入网设备B接收终端B的寻呼响应消息。
其中,当核心网设备接收到寻呼响应消息后,说明对终端B寻呼成功。
S105、核心网设备分别为终端A和终端B建立语音业务的用户 面陆地承载和无线承载。
其中,用户面陆地承载是指核心网设备与无线接入网设备之间的用户面连接,用户面无线承载是指无线接入网设备与终端之间的用户面连接。
可选的,核心网设备分别为终端A和终端B建立语音业务的无线承载的方案至少可以包括下述两种方案。
第一种方案:
核心网设备根据终端A的语音业务编解码能力、无线接入网设备A的语音业务编解码能力、终端B的语音业务编解码能力、无线接入网设备B的语音业务编解码能力以及自身配置的语音业务编解码能力,分别为终端A、终端B建立与五者中最低语音业务编解码能力对应的语音业务的无线承载。
示例性的,假设场景1为终端A及无线接入网设备A仅可提供AMR-NB语音业务;终端B及无线接入网设备B可提供AMR-WB和AMR-NB语音业务;核心网设备配置了提供AMR-NB和AMR-WB语音业务。
假设场景2为终端A及无线接入网设备A可提供AMR-WB及AMR-NB语音业务;终端B及无线接入网设备B的仅提供AMR-NB语音业务;核心网设备配置了提供AMR-NB和AMR-WB语音业务。
以上述场景1和场景2为例,无论哪个场景,终端A的语音业务编解码能力、无线接入网设备A的语音业务编解码能力、终端B的语音业务编解码能力、无线接入网设备B的语音业务编解码能力以及自身配置的语音业务编解码能力,五者中能力最低的为提供AMR-NB语音业务,因此,核心网分别为终端A、终端B建立AMR-NB语音业务的陆地承载和无线承载。
具体的,核心网设备为终端A建立AMR-NB语音业务的陆地承载和无线承载,具体包括下述步骤1至步骤5:
步骤1、核心网设备向无线接入网设备A发送AMR-NB业务指派;
步骤2、无线接入网设备A建立与核心网设备之间的陆地承载,建立与终端A之间的AMR-NB无线承载;
步骤3、终端A配置AMR-NB协议层;
步骤4、终端A向无线接入网设备A发送无线承载响应消息;
步骤5、无线接入网设备A向核心网设备A发送指派响应消息。
需要说明的是,核心网设备为终端B建立AMR-NB语音业务的陆地承载和无线承载的过程,与上述步骤1至步骤5类似,此处不再进行详细赘述。
第二种方案,包括S1051至S1053。
S1051、核心网设备根据终端A的最大语音业务编解码能力、无线接入网设备A的语音业务编解码能力以及自身配置的语音业务编解码能力,为终端A建立与三者中最低能力对应的语音业务的陆地承载和无线承载。
示例性的,以上述场景1为例,由于终端A的语音业务编解码能力最低,因此,核心网为终端A建立AMR-NB语音业务的陆地承载和无线承载。
示例性的,以上述场景2为例,由于终端A、无线接入网设备A及核心网设备的语音业务编解码能力一致,均可提供AMR-WB语音业务,因此,核心网为终端A建立AMR-WB语音业务的无线承载。
需要说明的是,核心网为终端A建立AMR-WB语音业务的连接和无线承载与上述步骤1至步骤5建立AMR-NB语音业务的连接和无线承载相似,仅是指派的业务类型不同,此处不再进行赘述。
S1052、核心网设备根据终端B的语音业务编解码能力、无线接入网设备B的能力、自身配置的语音业务编解码能力以及为终端A建立的语音业务的无线承载的类型,为终端B建立与四者中最低能力对应的语音业务的陆地承载和无线承载。
需要说明的是,为终端建立陆地承载和无线承载的过程,已经通过上述上述步骤1至步骤5进行了详细描述,此次不再进行赘述。
示例性的,以S1051中的场景1为例,核心网为终端A建立 AMR-NB语音业务的陆地承载和无线承载,终端B及无线接入网设备B可提供AMR-WB和AMR-WB语音业务;核心网设备可提供AMR-WB和AMR-WB语音业务;由于核心网为终端A建立的AMR-NB语音业务的陆地承载和无线承载能力最低,因此,核心网设备为终端B建立AMR-NB语音业务的陆地承载和无线承载。
示例性的,以是S1051中的场景2为例,核心网为终端A建立AMR-WB语音业务的陆地承载和无线承载,终端B及无线接入网设备B可提供AMR-NB,核心网设备可提供AMR-WB和AMR-WB语音业务;由于终端B及无线接入网设备B的能力最低,因此,核心网为终端B建立AMR-NB语音业务的陆地承载和无线承载。
S1053、核心网设备判断S1052建立的陆地承载和无线承载与S1051建立的陆地承载和无线承载的类型是否一致。
若一致,则S105步骤结束;若不一致,则执行S1054。
示例性的,以上述场景1为例,S1052建立的陆地承载和无线承载与S1051建立的陆地承载和无线承载的类型一致,则S105步骤结束。
示例性的,以上述场景2为例,S1052建立的陆地承载和无线承载与S1051建立的陆地承载和无线承载的类型不一致,则执行S1054。
S1054、核心网设备将终端A的陆地承载和无线承载修改为与终端B的陆地承载和无线承载的类型一致。
具体的,修改无线承载的过程,与建立陆地承载和无线承载的过程相似,此处不再进行赘述。
进一步的,在S1054之后,重新执行S1053。
需要说明的是,若S105采用上述第一种方案实现,则S105在S104之后执行。若S105采用上述第二种方案实现,则S1051与S104执行没有时间上的先后顺序,S1052在S104之后进行。
在S105之后,执行S106。
S106、核心网设备接收终端发起的业务请求,建立核心网设备 与终端间的用户面陆地承载。
至此,终端A与终端B开始进行语音业务,进行通话。
通话过程中,两端均产生AMR-NB语音信号,发送到对端。
有上述过程可知,只要有一端终端仅可提供AMR-NB语音业务,则两端终端进行AMR-NB语音业务。
实施例一
本发明实施例一提供一种建立无线承载的方法,应用于网络设备,所述网络设备可提供高语音质量编解码方式的语音业务。
具体的,所述可提供高语音质量编解码方式的语音业务是指:该设备的语音业务编解码能力配置为高语音质量编解码方式,且该功能打开。

其中,所述链路中所述网络设备至第一终端之间所有逻辑功能实体可提供高语音质量编解码方式的语音业务。
具体的,所述仅可提供低语音质量编解码方式的语音业务是指:该设备的语音业务编解码能力为低语音质量编解码方式;或者,所述仅可提供低语音质量编解码方式的语音业务是指:该设备的语音业务编解码能力配置为高语音质量编解码方式,且该功能关闭。
可选的,所述功能的关闭可以通过开关或者license控制。
可选的,当网络设备为第一终端时,可以为主叫端终端,也可以为被叫端终端,本发明对此不进行具体限定。
其中,所述网络设备可以为向第一终端提供接入服务的无线接入网设备或核心网设备;或者,所述网络设备为所述第一终端。
具体的,所述逻辑功能实体是指支撑语音业务功能的至少一个物理网元的集合。可选的,逻辑功能实体可以为单个物理网元,也 可以为多个物理网元,本发明对此不进行具体限定。
进一步的,当网络设备为第一终端时,可以为移动终端,也可以为固定终端,本发明对此也不进行具体限定。
可选的,当网络设备的是不同的物理网元时,所述网络设备判断第一终端与第二终端进行语音业务的端到端链路中,所述网络设备至第二终端之间是否存在至少一个逻辑功能实体仅可提供低语音质量编解码方式的语音业务的具体过程不同,具体可以包括但不限于下述三种方案:
方案1、所述网络设备为核心网设备。
可选的,在方案1中,核心网设备可以接收各个逻辑功能实体上报的各自的语音业务编解码能力之后判断执行S201。
其中,核心网设备可以接收各个逻辑功能实体上报的各自的语音业务编解码能力的过程,本发明不进行限定,可以根据实际需求设置。
可选的,在方案1中,也可以在核心网设备中预先配置好网络中各个逻辑功能实体的语音业务编解码能力,核心网设备直接读取各个逻辑功能实体的语音业务编解码能力进行判断执行S201。
方案2、所述网络设备为无线接入网设备。
可选的,在方案2中,所述判断第一终端与第二终端进行语音业务的端到端链路中,所述网络设备至第二终端之间是否存在至少一个逻辑功能实体仅可提供低语音质量编解码方式的语音业务,可以包括:
接收核心网设备发送的用于建立语音业务无线承载的指派消息;若所述指派消息指示建立低语音质量编解码方式无线承载,则所述链路中所述核心网设备至所述第二端终端之间存在至少一个逻辑功能实体仅可提供低语音质量编解码方式。
具体的,从图1所示的方法可知,核心网设备发送的指派消息指示建立的无线承载的类型,取决于链路中的逻辑功能实体业务能力中最低的业务能力,因此,若指派消息指示建立低语音质量编解 码方式无线承载,则链路中所述核心网设备至所述第二端终端之间存在至少一个逻辑功能实体仅可提供低语音质量编解码方式的语音业务,而无线接入网设备本身的语音业务编解码能力为高语音质量编解码方式,由此可知,所述链路中所述无线接入网设备至所述第二端终端之间存在至少一个逻辑功能实体仅可提供低语音质量编解码方式的语音业务。
可选的,在方案2中,也可以在无线接入网设备中预先配置好网络中各个逻辑功能实体的语音业务编解码能力,无线接入网设备直接读取各个逻辑功能实体的语音业务编解码能力进行判断执行S201。

接收无线接入网设备发送的用于配置协议层的指示消息;若指示消息指示配置低语音质量的协议层,则链路中所述网络设备至所述第二终端之间存在至少一个逻辑功能实体仅可提供低语音质量编解码方式的语音业务。
具体的,从图1所示的方法可知,无线接入网设备诶向终端发送的指示消息指示的业务类型,与核心网设备发送的指派消息指示建立的无线承载的类型一致,取决于链路中的逻辑功能实体业务能力中最低的业务能力,因此,若指示配置低语音质量的协议层,则链路中所述无线接入网设备至所述第二端终端之间存在至少一个逻辑功能实体仅可提供低语音质量编解码方式的语音业务,而第一终端本身的语音业务编解码能力为高语音质量编解码方式,由此可知,所述链路中所述第一终端至所述第二端终端之间存在至少一个逻辑功能实体仅可提供低语音质量编解码方式的语音业务。
可选的,在方案3中,也可以在无线接入网设备中预先配置好 网络中各个逻辑功能实体的语音业务编解码能力,无线接入网设备直接读取各个逻辑功能实体的语音业务编解码能力进行判断执行S201。
需要说明的是,上述三种方案并不是对执行S201的过程的具体限定,在实际应用中,可以根据实际需求确定执行S201的具体过程,本发明对此不进行具体限定。
示例性的,本发明所有实施例中的编解码方式可以包括但不限于下述方式(各编解码方式提供的语音业务的语音质量依次增高):AMR-NB、AMR-WB、EVS-NB、EVS-WB、EVS-SWB、EVS-FB。因此,当高语音质量编解码方式的类型不同时,低语音质量编解码方式可以有不同的定义,包括:
当高语音质量编解码方式为EVS-FB,则低语音质量编解码方式可以为EVS-SWB或者EVS-WB或者EVS-NB或者AMR-WB或者AMR-NB。
当高语音质量编解码方式为EVS SWB,则低语音质量编解码方式为可以为EVS-WB或者EVS-NB或者AMR-WB或者AMR-NB。
当高语音质量编解码方式为EVS-WB,则低语音质量编解码方式可以为EVS-NB或者AMR-WB或者AMR-NB。
当高语音质量编解码方式为EVS-NB,则低语音质量编解码方式可以为AMR-WB或者AMR-NB;
当高语音质量编解码方式为AMR-WB,则低语音质量编解码方式可以为AMR-NB。
需要说明的是,上述列举的编解码方式并不是对本发明所指的语音业务中编解码方式的限定,在实际应用中,可以根据实际需求设定高语音质量编解码方式的类型及与其对应的低语音质量编解码方式的类型,本发明对此不进行具体限定。凡是利用本发明的方案进行无线承载的建立,均属于本发明的保护范围。
可选的,若所述链路中所述网络设备至第二终端之间存在至少一个逻辑功能实体仅可提供低语音质量编解码方式的语音业务,则 执行S102。
可选的,若所述链路中所述网络设备至第二终端之间所有逻辑功能实体可提供高语音质量编解码方式的语音业务,则说明第一终端与第二终端进行语音业务的链路中所有逻辑功能实体均可提供高语音质量编解码方式的语音业务,则可以为第一终端和第二终端均建立进行高语音质量的语音业务的无线承载。具体的建立方法已经在图1的方案中进行了详细描述,此处不再进行赘述。
S102、网络设备为第一终端建立用于进行高语音质量编解码方式的语音业务的无线承载。
具体的,为所述第一终端建立用于进行高语音质量编解码方式的语音业务的无线承载,可以包括但不限于下述两种情况:
第一种情况:
若所述第一终端未建立无线承载,为所述第一终端新建立用于进行高语音质量编解码方式的语音业务的无线承载。
其中,上述第一种情况为第一终端初次建立无线承载的情况。
第二种情况:
若所述第一终端已建立用于进行高语音质量编解码方式的语音业务的无线承载,保持所述第一终端的无线承载不变。
其中,上述第二种情况为第一终端初次建立无线承载之后,由于系统性能的限制,对第一终端建立的无线承载的类型需要进行修改,进行二次指派(即晚指派)的情况。
可选的,当网络设备为不同的物理网元时,所述为所述第一终端建立用于进行高语音质量编解码方式的语音业务的无线承载的具体过程也不同,可以包括下述三种情况:
第一种情况,所述网络设备为核心网设备。
在该情况中,为所述第一终端建立用于进行高语音质量编解码方式的语音业务的无线承载,可以包括:
向为所述第一终端提供服务的无线接入网设备发送用于建立高语音质量编解码方式的语音业务无线承载的指派消息。
进一步的,在该第一种情况中,网络设备为核心网设备,在所述为第一终端建立用于进行高语音质量编解码方式的语音业务的无线承载之后,所述方法还可以包括:向为所述第二终端提供服务的无线接入网设备发送用于建立低语音质量编解码方式的语音业务无线承载的指派消息。
需要说明的是,对于建立无线承载的具体过程,已经在图1所示的方法中进行了详细描述,此处不再进行赘述。
第二种情况,所述网络设备为无线接入网设备。
在该情况中,为所述第一终端建立用于进行高语音质量编解码方式的语音业务的无线承载,可以包括:

第三种情况,所述网络设备为第一终端。
在该情况中,所述为所述第一终端建立用于进行高语音质量编解码方式的语音业务的无线承载,可以包括:
所述第一终端配置高语音质量的协议层。
这样一来,通过本发明示例提供的建立无线承载的方法,网络设备为第一终端建立的无线承载与链路中网络设备至第二移动台之间的逻辑功能实体的业务能力不同,相当于在网络设备中配置了隔离转换功能,通过该功能隔离了信令面消息,达到网络设备两侧建立的无线承载类型不同的目的。
进一步的,在为所述第一终端建立用于进行高语音质量编解码方式的语音业务的无线承载之后,所述方法还可以包括:
接收高语音质量编解码方式的语音数据,降采样转换为低语音质量编解码方式的语音数据后发送;
或者,
接收低语音质量编解码方式的语音数据,扩频转换为高语音质量编解码方式的语音数据后发送。
这样一来,网络设备将接收的语音数据的类型转换为适合该语音数据即将传输的无线承载传输的类型后再进行发送,相当于在网络设备中配置了隔离转换功能,通过该功能转换了用户面数据,达到网络设备两侧不同类型的用户数据的转换目的。
需要说明的是,本发明所有实施例提供的建立无线承载的方法,可以应用于各种通信制式中,所述各种通信制式可以包括但不限于下述制式中的一种:全球移动通信系统(Global System for Mobile Communication,简称GSM)、宽带码分多址(Wideband Code Division Multiple Access,简称WCDMA)系统、时分同步码分多址(Time Division-Synchronous Code Division Multiple Access,简称TD-SCDMA)系统、码分多址(Code Division Multiple Access,简称CDMA)系统、长期演进(Long Term Evolution,简称LTE)。
进一步的,在不同的制式中,本发明所有实施例所述的无线接入网设备及核心网设备的类型不同。
本发明所有实施例所述的无线接入网设备及核心网设备的类型包括但不限于:
若通信网络为WCDMA系统或者TD-SCDMA系统,无线接入网设备为无线网络控制器(Radio Network Controller,简称RNC),核心网设备为移动交换中心(Mobile Switching Center,简称MSC)。

若通信网络为LTE系统,无线接入网设备为演进型基站(Evolved Node B,简称eNodeB),核心网设备为移动管理实体(Mobility Management Entity,简称MME)。
本发明实施例提供的建立无线承载的方法,应用于网络设备,所述网络设备可提供高语音质量编解码方式的语音业务;通过判断第一终端与第二终端进行语音业务的端到端链路中,所述网络设备至第二终端之间是否存在至少一个逻辑功能实体仅可提供低语音质量编解码方式的语音业务;其中,所述链路中所述网络设备至第一 终端之间所有逻辑功能实体可提供高语音质量编解码方式的语音业务;若所述链路中所述网络设备至第二终端之间存在至少一个逻辑功能实体仅可提供低语音质量编解码方式的语音业务,为所述第一终端建立用于进行高语音质量编解码方式的语音业务的无线承载。这样一来,在链路中网络设备至第二终端之间存在至少一个逻辑功能实体仅可提供低语音质量编解码方式的语音业务时,网络设备为第一终端建立的无线承载是进行高语音质量编解码方式的语音业务的无线承载,未受到网络设备至第二终端之间的逻辑功能实体的业务能力的限制,克服了现有技术中进行语音业务的无线承载的类型由所有通信设备中语音业务编解码能力最低的语音业务编解码能力决定的缺陷,因此,本发明实现了可提供高质量编解码方式语音业务的终端侧用户可以体验高清语音业务,使得终端的用户体验与终端能力一致,提高了其用户体验度。
