本发明实施例涉及通信技术,尤其涉及一种无线连接建立方法及设备。
随着可穿戴设备(Wearable equipment,简称:WE)的蓬勃发展,可穿戴设备被广泛应用在人们的日常生活中。但考虑到可穿戴设备体积小、电池容量小、功耗低的特点,可穿戴设备不能与蜂窝网的网络设备直接进行通信,可穿戴设备需要通过中继设备与蜂窝网的网络设备进行通信,使得网络设备为可穿戴设备提供服务。例如可穿戴设备获取的数据包括可穿戴设备获取的佩戴者的生理数据,中继设备可以为可穿戴设备的佩戴者的智能移动终端,可穿戴设备也可以作为便捷的随身通信工具,为佩戴者提供接收短信、查看时间及位置定位等服务。
在可穿戴设备通过中继设备与蜂窝网的网络设备的通信过程中,可穿戴设备和中继设备的通信方式可以使用非蜂窝网协议传输技术,例如蓝牙技术。基于蓝牙技术的协议栈中,逻辑链路控制和适配协议(Logical Link Control and Adaptation Protocol,简称:L2CAP)层之上还有多种协议层,例如,蜂窝网的协议层,因此,L2CAP层需要知道明确发送或接收的数据需要送到哪一协议栈实体进行处理。其中,L2CAP层的协议数据单元(Protocol Data Unit,简称:PDU)包头中有一个协议/服务复用(Protocol/Service Multiplexer,简称:PSM)域。这个PSM域的长度为16位比特,其已经在蓝牙技术联盟(Bluetooth Special Interest Group,简称:BT SIG)中定义了一些值,还有一些值是通过服务发现协议(Service discovery protocol,简称:SDP)实现动态分配。只有在收发双方对于PSM的认识是一致的情况下,才能让数据包得到正确的解析。因此在不进行非蜂窝网协议的标准化改动的前提下,如何使得收发双方对于PSM的认识是一致的,成为当前亟需解决的问题。

可选的,第二终端协议栈12的第二RLC层114之上设置有第二PDCP层118;
网络设备协议栈13的蜂窝网PDCP层111与第二RLC层114之间设置有:与第二终端协议栈12对等的第二PDCP层118。

网络设备协议栈13的蜂窝网PDCP层111之下设置有:与第一协议栈11对等的蜂窝网MAC层120。
通过图2a所示的用户面协议栈,对于上行传输数据,第一终端将来自蜂窝网模块的数据包在蜂窝网PDCP层进行安全处理后,通过第二终端发送至网络设备。对于下行传输数据,网络设备将来自核心网的数据包在蜂窝网PDCP层进行安全处理后,通过第二终端发送至第一终端。
图2b所示的控制面协议栈10包括第一终端协议栈11、第二终端协议栈12和网络设备协议栈13,图2b所示的控制面协议栈10在图2a所示的用户面协议栈10的基础上,如图2b所示,增加如下内容:
第一终端协议栈11的蜂窝网PDCP层111之上设置有蜂窝网RRC层119,网络设备协议栈13的蜂窝网PDCP层111之上设置有与第一终端协议栈11对等的蜂窝网RRC层119。

对于第一终端协议栈中的适配层112,按照适配层112实现的功能划分,如图3a所示,该适配层112包括协议数据包转换单元1121和配置单元1122。其中,
协议数据包转换单元1121用于实现将数据包在基于蓝牙协议的数据包与蜂窝网数据包(即基于蜂窝网协议的数据包)之间转换的功能,或者将数据包在基于Wi-Fi协议的数据包与蜂窝网数据包之间转换的功能。具体的,基于蓝牙协议或Wi-Fi协议,协议数据包转换单元1121对数据包进行字节序的转换,和/或,添加或删除数据包的部分包头内容。对于上行传输数据,协议数据包转换单元1121将蜂窝网模块产生的蜂窝网数据包转换成基于蓝牙协议或Wi-Fi协议的数据包,进而实现第一终端将转换后的数据包发送至第二终端。对于下行传输数据,协议数据包转换单元1121将来自第二终端的基于蓝牙协议或Wi-Fi协议的数据包转换成蜂窝网数据包,并递交至蜂窝网模块做进一步处理。其中,蜂窝网模块的协议层至少包括蜂窝网RRC层和/或蜂窝网PDCP层。
配置单元1122用于实现配置预设协议栈113的参数信息的功能,还可以用于实现对无线承载的数据包进行QoS等级映射的功能。配置单元1122用于根据蜂窝网的承载配置信息,来配置基于蓝牙协议或Wi-Fi协议的预设协议栈113中各个协议层的参数。
蜂窝网的无线承载配置信息通常包含有蜂窝网RLC层和/或蜂窝网MAC层的配置参数,这些配置参数的目的是能够保证协议发送端和接收端可靠的传输数据并且保证一定的数据传输速率。
例如,蜂窝网的承载配置信息和蓝牙协议下的配置信息的对应关系如下:
当蜂窝网RLC层配置为应答模式(Acknowledge Mode,简称:AM)时,基于蓝牙协议的预设协议栈中的L2CAP层应当配置为有接收端确认的模式;当蜂窝网MAC层配置有保证比特速率(Guaranteed Bit Rate,简称:PBR)时,则蓝牙协议下配置的信道个数应满足PBR的值。或者,
蜂窝网的承载配置信息包含QoS级别标识符(QoS Class Identifier,简称:QCI),这个QCI值对应蓝牙协议下的数据传输速率和数据传输模式(包括确认的传输模式、重传的传输模式以及无确认的传输模式)。根据QCI来配置L2CAP层的信道个数,数据包的最大值,重传次数等。
对于第二终端协议栈的第一接口侧的协议栈中的适配层112,按照适配层112实现的功能划分,如图3b所示,该适配层112包括协议数据包转换单元1121、配置单元1122以及数据包转发单元1123。
图3b所示的适配层112与图3a所示的适配层112区别在于,图3b所示的适配层112增加了数据包转发单元1123,数据包转发单元1123用于实现适配层112与第二RLC层或第二PDCP层传输数据包的功能。对于上行传输数据包,协议数据包转换单元1121对将来自第一终端的基于蓝牙协议或Wi-Fi协议的数据包转换成蜂窝网数据包,数据包转发单元1123将该蜂窝网数据包递交给第二RLC层或第二PDCP层,进而实现第二终端将蜂窝网数据包发送至网络设备。对于下行传输数据包,数据包转发单元1123接收来自第二RLC层或或第二PDCP层的蜂窝网数据包,数据包转发单元1123将该蜂窝网数据包递交给协议数据包转换单元1121,协议数据包转换单元1121将该蜂窝网数据包转换为基于蓝牙协议或Wi-Fi协议的数据包,进而实现第二终端将基于蓝牙协议或Wi-Fi协议的数据包发送至第一终端。
需要说明的是,协议栈中的适配层可以是一个独立的实体,以实现其具有的功能;也可以通过其他现有的协议层实现该适配层具有的功能,例如,通过蜂窝网RRC层实现适配层的配置单元1122具有的功能,通过蜂窝网PDCP层实现适配层的协议数据包转换单元1121和数据包转发单元1123具有的功能。
通过上述协议栈,能够使得第一终端通过第二终端的无线连接与网络设备进行通信,以在不进行非蜂窝网协议的标准化改动的前提下,使得收发双方对于各自非蜂窝网协议中逻辑链路控制协议层或者媒体接入控制层的上层的数据包的协议类型或者服务属性(例如PSM)的认识一致。
下面结合上述协议栈,详细说明本发明实施例提供的一种无线连接建立方法。
图4为本发明无线连接建立方法实施例一的流程图。本发明实施例提
供一种无线连接建立方法,该方法可以由终端(例如本发明实施例中的第一终端)执行。如图4所示,该无线连接建立方法包括:
S401、第一终端获取参数信息,该参数信息用于指示数据包的协议类型或者服务属性。
其中,数据包的协议类型可以理解为生成数据包所使用的协议的类型;数据包的服务属性可以理解为某一属性的服务中所传输的数据包。
需要说明的是,第一终端获取参数信息可通过多种方式实现:可以是从其他设备获取参数信息,例如,基站将参数信息下发给第一终端;也可以是第一终端根据配置信息预先生成并存储的参数信息,等等。
S402、第一终端根据参数信息,与第二终端建立无线连接,该无线连接使用非蜂窝网协议传输技术,第一终端通过第二终端的无线连接与网络设备传输所述协议类型或者服务属性的数据包。
由于参数信息指示了数据包的协议类型或者服务属性,因此,当第一终端根据参数信息,与第二终端建立无线连接之后,第一终端可通过与第二终端的无线连接,与网络设备之间传输参数信息所指示的协议类型或者服务属性的数据包。
在第一终端通过第二终端的无线连接与网络设备传输数据包的过程中,第一终端和第二终端均具备数据包转换功能,数据包转换功能是指将传输的数据包在基于所述协议类型或者服务属性的数据包与蜂窝网数据包之间转换。例如,图3a所示的协议数据包转换单元1121即用于实现将数据包在基于蓝牙协议的数据包与蜂窝网数据包(即基于蜂窝网协议的数据包)之间转换的功能,或者将数据包在基于Wi-Fi协议的数据包与蜂窝网数据包之间转换的功能。
对应地,以第二终端为执行主体,则为第二终端与第一终端建立无线连接。
当第一终端与第二终端之间的无线连接需要支持多种协议数据包的传输时,这些属于多个协议类型或者服务属性的数据包需要能够被终端中能够处理对应的协议的模块进行处理,因此,无线连接的逻辑链路控制协议层或者媒体接入控制层需要获知每个数据包所属的协议类型,以便能够将这个数据包递交给对应的协议模块实体进行处理,因此在逻辑链路控制协议层或者媒
体接入控制层的数据包的包头中设置一个字段来指明该数据包的服务协议数据单元对应的协议类型,或者逻辑链路控制协议层或者媒体接入控制层的信道只用于传输所述协议类型的数据包时要与对端(接收端或者发送端)进行通知。为了数据包的收发两端能够正确解析一个协议类型的数据包,必须要对逻辑链路控制协议层或者媒体接入控制层的数据包的包头中的协议类型进行标准化定义,即若所述无线连接的逻辑链路控制协议层或者媒体接入控制层的服务协议数据单元对应的协议有N个,则这个媒体接入控制层的数据包的包头中的值必须有N个。或者是收发两端使用专有的信道传输复用指示信息来指明自身的信道号与协议类型或者服务属性的对应关系。本发明实施例在现有的无线连接的逻辑链路控制协议层或媒体接入控制层上新增加一个支持服务协议类型。
现有技术是在所述协议的标准化文本中增加一个服务协议类型的定义,这个增加的定义就叫做标准化改动,但标准化改动之后,旧的已经生产的设备是不能支持这个新增加的特性的,不能实现前向兼容。
本发明实施例通过第一终端与第二终端建立无线连接,该无线连接使用非蜂窝网协议传输技术,实现第一终端通过第二终端的无线连接与网络设备传输网络设备能够识别的协议类型或者服务属性的数据包,以在不进行非蜂窝网协议的标准化改动的前提下,使得收发双方,即第一终端与第二终端,对于各自非蜂窝网协议中逻辑链路控制协议层或者媒体接入控制层的上层的数据包的协议类型或者服务属性(例如PSM)的认识一致。
在上述实施例中,参数信息可至少包括蜂窝网协议服务标识、蜂窝网协议的版本号、蜂窝网协议类型对应的PSM值中任一个。其中,蜂窝网协议服务标识、蜂窝网协议的版本号或者蜂窝网协议类型与至少一个PSM值对应。
根据第一终端获取参数信息的实现方式的不同,下面采用几个具体的实施例,对图4所示方法实施例的技术方案进行详细说明。
在第一种实现方式中,参照图5,第一终端获取参数信息可以包括:S501、第一终端接收网络设备发送的第二消息。
其中,网络设备可以包括接入网设备和核心网设备等。具体地,第一终端接收接入网设备发送的RRC消息,该RRC消息携带上述参数信息,RRC消息可以包括系统广播消息,或者针对第一终端的独立信令,例如,RRC消
息为包含系统信息块(System Information Block,简称:SIB)(例如SIB25)的系统广播消息,其中,SIB25中携带上述参数信息;或者,第一设备接收核心网设备发送的NAS消息,该NAS消息携带上述参数信息。可选地,参数信息携带在NAS消息的蓝牙参数信元块(BT parameter信元块)。其中,接入网设备包括基站、接入网控制单元等,核心网设备包括资源协商单元(Resource Control Unit,简称:RCU)。接入网控制单元例如为无线电网络控制器(Radio Network Controller,简称:RNC)。
示例性的,当终端(包括第一终端和第二终端)驻留在基站的覆盖区域内时,终端接收到基站发送的包含SIB25的系统广播消息。可选地,终端存储系统广播消息中携带的内容,包括参数信息等。
图5所示信令交互流程以非蜂窝网协议传输技术为蓝牙技术为例进行说明,但本发明实施例不以此为限制。
上述第一终端根据参数信息,与第二终端建立无线连接,可以包括以下步骤:
S502、在第一终端检测到该第一终端的蓝牙功能被打开时,第一终端发送探测请求消息。
该探测请求消息携带第一终端的标识以及第一终端的数据包协议或者服务属性的参数信息。
对应地,第二终端接收第一终端发送的探测请求消息。
具体地,在终端包括(第一终端和第二终端)的蓝牙功能打开时,终端发送探测请求消息来发现能够和自己配对的其他终端,该其他终端的蓝牙功能也处于开启状态。所述探测请求消息中携带从参数信息,用以通知其他终端:自己的L2CAP层的上层支持的协议类型为蜂窝网协议的某个版本时,PSM值是xxx,其中xxx可表示任意值。这样,接收到这个探测请求消息终端即可获知发送该探测请求消息的终端所支持的蜂窝协议的PSM值。
以LTE系统的rel-14举例说明:终端的扫描发现过程来获得PSM值。
第一终端存储自己支持的LTE r14的PSM值为0xF001,服务的名称为LTE r14(ASCII),UUID=0xFFEF。当第一终端检测到第一终端的蓝牙功能被打开时,第一终端发送探测请求消息,该探测请求消息携带第一终端的上述内容。接收到该探测请求消息的其他终端(包括第二终端)即可记录该第一
终端的上述内容:BT设备001支持LTE r14,PSM=0xF001。其中,“BT设备001”用于表示第一终端的标识。
同理,当第二终端存储自己支持的LTE r14的PSM值为0xF009,服务的名称为LTE r14(ASCII),UUID=0xFFEF。当第二终端检测到第二终端的蓝牙功能被打开时,第二终端发送探测请求消息,该探测请求消息携带第二终端的上述内容。接收到该探测请求消息的其他终端(包括第一终端)即可记录该第二终端的上述内容:BT设备002支持LTE r14,PSM=0xF009。其中,“BT设备002”用于表示第二终端的标识。
S503、第二终端根据探测请求消息,生成探测应答消息。
该探测应答消息携带第二终端的标识。
S504、第一终端接收第二终端发送的探测应答消息。
S505、第一终端发送逻辑链接请求消息给第二终端。
该逻辑链接请求消息中携带第一终端的信道标识及第一终端的PSM值。例如,第一终端的信道标识为:channelID=0x2800;第一终端的PSM值为:PSM=0xF001。其中,第一终端预先为自身的LTE r14的协议栈实体的消息发送信道分配信道标识,例如,channelID=0x2800,表明从0x2800信道来的数据它的协议类型为0xF001即LTe r14。
对应地,第二终端接收第一终端发送的逻辑链接请求消息。可选地,第二终端存储第一终端的信道标识。
S506、第二终端确定来自第一终端的信道标识的数据由第二终端的PSM值对应的协议栈实体处理。
例如,第二终端确定来自channelID=0x2800的数据由LTE r14对应的协议栈实体处理。
S507、第二终端发送逻辑链接应答消息给第一终端。
该逻辑链接应答消息中携带第二终端的信道标识及第一终端的信道标识。第二终端的信道标识用于指示第一终端将来自第二终端的信道标识的数据由第一终端的PSM值对应的协议栈实体处理。例如,第二终端为自身的LTE r14的协议栈实体的消息发送信道分配信道标识,例如,channelID=0x1900。
对应地,第一终端接收第二终端发送的逻辑链接应答消息。
S508、第一终端确定来自第二终端的信道标识的数据由第一终端的PSM值对应的协议栈实体处理。
例如,第一终端确定来自channelID=0x1900的数据由LTE r14对应的协议栈实体处理。
通过上述S502至S508,第一终端和第二终端可分别使用各自的L2CAP层来发送/接收对端的支持LTE r14的蜂窝网协议的数据包。第二终端的适配层就会从基于蓝牙协议的L2CAP层收到第一终端发送过来的RRC消息或者PDCP数据包;然后,按照适配层的功能来进行处理。同样的,第二终端也可以在从基站接收到需要发送给第一终端的数据包之后,在其适配层中进行处理;然后,递交给channelID=0x1900的L2CAP层处理并发送。第一终端从第二终端的channelID=0x1900收到数据包之后,根据信道标识和PSM值的对应关系,将这个数据包送到支持LTE r14的蜂窝网协议的适配层(在第一终端内部)实体进行处理。
可选地,本发明实施例中的参数信息还可以包括:蜂窝网协议中的QoS参数与蓝牙技术中L2CAP参数的对应关系。进一步地,参数信息还可以包括:终端(包括第一终端和第二终端)可作为服务器(server)的指示信息,或可以作为服务器(server)及客户端(client)的指示信息。
在第二种实现方式中,参照图6,第一终端获取参数信息可以包括:S601、第一终端获取预先配置的参数信息。
该实现方式与第一种实现方式的区别在于:在第一种实现方式中,第一终端从网络设备获取参数信息;在第二种实现方式中,第一终端自身生成参数信息。
该实现方式中,第一终端根据参数信息,与第二终端建立无线连接,可以包括以下步骤:
S602、在第一终端检测到第一终端的短距无线或者低功耗无线功能被打开,且第一终端在短距无线或者低功耗无线信道探测到第二终端时,第一终端发送第一消息给网络设备。
其中,该第一消息携带第二终端的标识。该第一消息用于指示第一终端发现用于建立无线连接的第二终端。第一终端与网络设备已建立连接,例如蜂窝网连接。该第一消息可以为RRC消息或者MAC层的控制消息等。
另外,短距无线或者低功耗无线功能包括但不限于Wi-Fi功能,无线保真直通(Wi-Fi direct)功能、BLE功能、BT功能、zigbee功能等。
可选地,该第一消息还可以包括:第二终端的服务小区标识。
进一步地,该第一消息还可以包括:第一终端的PSM值。该第一终端的PSM值用于指示第一终端中短距无线或者低功耗无线技术的逻辑链路控制协议层的上层数据协议为蜂窝网协议。
S603、网络设备发送第一短距无线或者低功耗无线终端配对消息给第一终端;网络设备发送第二短距无线或者低功耗无线终端配对消息给第二终端。
该第一短距无线或者低功耗无线终端配对消息至少携带第二终端的PSM值。该第二终端的PSM值用于指示第二终端中短距无线或者低功耗无线技术的逻辑链路控制协议层的上层数据协议为蜂窝网协议,或者,第二终端的PSM值与蜂窝RB一一对应。
该第二短距无线或者低功耗无线终端配对消息至少携带第一终端的PSM值。该第一终端的PSM值用于指示第一终端中短距无线或者低功耗无线技术的逻辑链路控制协议层的上层数据协议为蜂窝网协议,或者,第一终端的PSM值与蜂窝RB一一对应。
当终端(包括第一终端和第二终端)与基站存在多个蜂窝RB连接时,为每个蜂窝RB的协议实体分配一个PSM值,这样,终端的数据包头或者每个蓝牙信道都会对应一个PSM值。
对应地,第一终端接收网络设备发送的第一短距无线或者低功耗无线终端配对消息;第二终端接收网络设备发送的第二短距无线或者低功耗无线终端配对消息。
S604、第一终端根据第二终端的PSM值,配置第一终端的逻辑链路控制协议层或适配层,与第二终端建立无线连接。
其中,该步骤基于蓝牙协议。
或者,该步骤可替换为:第一终端根据第二终端的PSM值,配置第一终端的MAC层或适配层,与第二终端建立无线连接。此时,该步骤基于Wi-Fi协议。
另外,第二终端与第一终端建立无线连接可以包括:S605、第二终端根据第一终端的PSM值,配置第二终端的逻辑链路控制协议层或适配层,与第
一终端建立无线连接。
同理,S605基于蓝牙协议。
或者,该步骤可替换为:第二终端根据第一终端的PSM值,配置第二终端的MAC层或适配层,与第一终端建立无线连接。此时,该步骤基于Wi-Fi协议。
参考图2a、图2b、图3a和图3b,第一终端或第二终端的RRC层配置基于蓝牙协议的L2CAP层,或者,RRC层配置适配层,由适配层和基于蓝牙协议的L2CAP层进行交互;或者,第一终端或第二终端的RRC层配置基于Wi-Fi协议的MAC层,或者,RRC层配置适配层,由适配层和基于Wi-Fi协议的MAC进行交互。
在该发明实施例中,由于PSM值是通过终端与网络设备的蜂窝网链路直接配置给对端终端,也就是,第一终端的PSM值配置给第二终端,第二终端的PSM值配置给第一终端,所以第一终端与第二终端的无线连接就会按照所述要求进行建立,不会出现第一终端与第二终端对于支持的同一个协议的PSM值描述不同所导致的不能正确处理数据包的情况发生。
还需说明的是,本发明实施例中的蜂窝网协议包括但不限于2G、3G和4G已经在商用的协议类型,还包括5G协议类型等。
