Abstract

本申请提供了一种无线通信的方法和无线通信装置,无线通信装置以第一用户的身份附着到第一网络,并保持和第一网络的RRC连接;同时以第二用户的身份附着到第二网络,并在第二网络处于空闲态。无线通信装置在接收到第二网络的寻呼消息,请求无线通信装置处理第一业务的情况下,无线通信装置请求第一网络释放第一用户的RRC连接,同时建立第二用户和第二网络的RRC连接。由于无线通信装置主动请求第一网络释放第一用户的RRC连接,使得第一网络可以获知第一用户的RRC连接的状态变化,可以避免无线通信装置直接释放第一用户的RRC连接,而第一网络对此并不感知的而带来的问题,有助于降低消息和/或信令丢失的概率,提高呼通率。

Description

无线通信的方法和无线通信装置 技术领域
本申请涉及无线通信技术领域,更具体地,涉及一种无线通信的方法和无线通信装置。
背景技术
用户身份识别模块(subscriber identity module,SIM)是手机上的一个基本模块,它存储了无线通信系统的签约用户的身份验证、鉴权和加密相关的信息,主要用于对用户身份进行识别。早期的手机都是单SIM,但是随着人们生活圈和工作圈的扩大,同时为了兼顾不同运营商资费的优势,单个SIM的手机已经无法满足人们的需求。在这种需求的拉动下,并随着智能手机技术的快速发展,双SIM的手机应运而生。
早期的双SIM手机的每个SIM都采用各自独立的一套基带芯片、射频芯片以及存储器系统。或者说,双SIM手机具有两套基带芯片、射频芯片以及存储器系统,相当于将两套芯片组装,而功耗基本也是单SIM手机的两倍。
为了节省成本,提高市场竞争力,目前的双SIM手机的射频基本都采用双收单发的模式。其中,双收单发是指,在任何一个时间,终端设备仅支持使用一个射频发射通道和两个射频接收通道。通过仅配置一套射频发送通道资源,从而节省了成本。终端设备可以通过该两个射频接收通道接收来自两个公共陆地移动网络(public land mobile network,PLMN)的信号,但是不能同时保持和两个PLMN的无线资源控制(radio resource control,RRC)连接。因此,在任何一个时间,只有一个SIM处于连接态,而另一个SIM处于空闲态。
目前,从用户反馈来看,采用双收单发模式的终端设备,普遍存在大概率丢失消息或信令,以及呼通率低的问题。

应理解,基站有时也称为无线接入点(access point,AP)、发送接收点(transmission reception point,TRP)或发送节点(transmission point,TP)。具体地,基站可以是第五代(5 th generation,5G)系统中的通用节点B(generation Node B,gNB)、长期演进(long term evolution,LTE)系统中的演进节点B(evolutional Node B,eNB)。此外,根据基站的物理形态或发射功率的不同,基站可被分为宏基站(macro base station)或微基站(micro base station)。微基站有时也被称为小基站或小小区(small cell)。
此外,网络设备还可以为构成gNB或TRP的网络节点,例如,基带单元(building baseband unit,BBU)、集中式单元(centralized unit,CU)或分布式单元(distributed unit,DU)等。
使用无线网络服务的设备可以简称为终端(terminal)。终端能够与网络设备之间建立连接,并基于网络设备的服务为用户(user)提供无线通信业务。应理解,由于终端与用户的关系更加紧密,终端有时也被称为用户设备(user equipment,UE)或订户单元(subscriber unit,SU)。此外,相对于通常在固定地方放置的基站,终端往往随着用户一起移动,有时也被称为移动台(mobile station,MS)。此外,有些网络设备,例如,中继节点(relay node,RN)或者无线路由器等,由于具有UE身份,或者归属于用户,在一些情况下也被认为是终端。
具体地,终端可以是移动电话(mobile phone),平板电脑(tablet computer),膝上型电脑(laptop computer)、可穿戴设备(例如,智能手表、智能手环、智能头盔、智能眼镜等),以及其他具备无线接入能力的设备,例如,智能汽车,各种物联网(internet of  thing,IOT)设备,包括各种智能家居设备(例如,智能电表和智能家电)以及智能城市设备(例如,安防或监控设备,智能道路交通设施)、5G系统或者以后的通信系统中的终端设备等。
参见图1,图1的(a)和(b)为适用于本申请实施例的无线通信系统的架构图。如图1所示,该无线通信系统包括至少一个网络设备以及一个或多个终端设备。所述至少一个网络设备以及一个或多个终端设备采用无线通信技术进行通信。图1中,101和103均代表网络设备,102代表终端设备。
在申请中,终端设备可以具有两个用户识别模块(subscriber identity modula,SIM)。终端设备的所述两个SIM可以连接同一个网络设备,如图1的(a)所示。或者,所述两个SIM可以连接不同的网络设备,如图1的(b)所示。
在终端设备的所述两个SIM连接不同的网络设备的场景下,所述两个SIM分别连接的网络设备可以属于同一个运营商,也可以分别属于不同的运营商。例如,一个SIM可以连接到中国移动提供的网络设备,另一个SIM可以连接到中国联通提供的网络设备。又例如,两个SIM均连接到中国移动提供的网络设备。
此外,终端设备的所述两个SIM可以分别连接不同通信系统的网络设备。例如,一个SIM连接中国移动的5G系统的网络设备,另一个SIM连接中国移动的LTE系统的网络设备。或者,终端设备的所述两个SIM可以连接同一个通信系统的网络设备。例如,一个SIM连接5G系统的一个网络设备,另一个SIM连接5G系统的另一个网络设备。又例如,所述两个SIM均连接5G系统的同一个网络设备。随着通信系统的演进,终端设备的SIM也可以连接5G以后的通信系统的网络设备。
可选地,终端设备的所述两个SIM也可以替换为通用用户识别模块(universal subscriber identity module,USIM)。或者,两个SIM中的一个SIM替换为USIM。
在一种实现中,终端设备可以具有多个卡槽,每个卡槽可以安装一个SIM。例如,在本申请的方案中,终端设备可以具有两个卡槽,每个卡槽安装一个SIM。
可选地,在另一种实现中,终端设备上的通用集成电路卡(universal intergrated circuit card,UICC)可以存储多个SIMs。在这种情况下,终端设备的所述两个SIM可以均存储在UICC中。或者,所述两个SIM中的一个SIM存储在UICC中,在这种情况下,终端设备可以具有一个卡槽,该卡槽用于安装另外一个SIM。
或者,在另一种实现中,终端设备的多个SIMs各自存储的信息可以直接存储在终端的存储系统中,而无需卡槽或者UICC。不同SIM对应的信息可以分别存储在存储系统的不同位置,或者也可以存储在相同的位置。例如,虚拟SIM(v-SIM)、嵌入式SIM(embbed SIM,e-SIM)和软件SIM(soft-SIM)等类型的SIM。
应理解,图1仅以终端设备102作为终端设备的示例,说明终端设备和网络设备之间的连接关系。无线通信系统中还可以包括更多的终端设备和网络设备。
本申请的技术方案适用于具有两个SIM或者两个以上的SIM的终端设备。本申请中以具有两个SIM的终端设备作为示例进行说明,在终端设备具有两个以上的SIM的情况下,对于双收单发的终端设备,在同一个时刻,当有一个SIM处于连接态时,其它的SIM将处于空闲态。处于连接态的SIM和处于空闲态的任意一个SIM,则相当于本申请中的第一SIM和第二SIM。
可选地,具有两个SIM的终端设备也称为双SIM终端设备或者双卡UE。这里,“卡”即是指SIM(或者,SIM卡)。
可以理解的是,终端设备和网络设备之间交互信令和数据,首先需要和网络设备之间建立无线资源控制(radio resource control,RRC)连接。终端设备和网络设备之间建立了RRC连接的情况下,终端设备处于连接态。终端设备和网络设备之间没有建立RRC连接(或者说,RRC连接处于断开的状态),终端设备则处于空闲态。处连接态的终端设备可以向网络设备发送信令和/或数据,也可以接收来自网络设备的信令和/或数据。处于空闲态的终端设备不能向网络设备发送信令和/或数据,但是可以接收来自网络设备的寻呼消息。因此,处于空闲态的终端设备要发送信令和/或数据,需要先进入连接态。
目前,具有两个SIM的终端设备基本都采用双收单发的模式,下面结合图2进行说明。
参见图2,图2为双收单发模式的结构示意图。对于支持双收单发模式的终端设备,在任何一个时间,终端设备可以支持同时接收来自两个移动网络,例如,公用陆地移动网络(public land mobile network,PLMN),的信号,但是不支持同时维持和两个移动网络的RRC连接。因此,在两个SIM中的一个SIM处于RRC连接态时,另一个SIM将处于空闲态。例如,图2示出了终端设备的射频集成电路(radio frequency integrated circuit,RFIC)的部分结构。终端设备的基带处理器建立SIM和RFIC上的射频接收通道(例如,Rx0和Rx1)和射频发射通道(例如,Tx0)之间的映射关系。例如,SIM0和Tx0、Rx0对应,SIM1和Rx1对应。其中,Tx0和Rx0和天线1连接,SIM0对应的用户既可以通过Rx0接收信号,也可以通过Tx0发射信号,处于连接态。Rx1和天线2连接,SIM1对应的用户只可以通过Rx1接收信号,处于空闲态。如果SIM 1需要使用射频发射通道Tx0发射信号,则基带处理器需要重新建立SIM0、SIM1和射频通道的映射关系。例如,重新建立映射后,SIM 0和Rx0对应,SIM1和Rx1、Rx0对应。之后,射频发射通道Tx0将被SIM 1对应的用户使用。SIM0对应的用户只能接收信号,进入空闲态,而SIM1对应的用户既可以接收信号,也可以发送信号,进入连接态。
应理解,图2仅是用于描述双收单发模式的示意图,实际的RFIC以及射频系统包括更复杂的结构。并且,RFIC通过射频前端(radio frequency front end,RFFE)器件连接到天线。
采用双收单发工作模式的终端设备,普遍存在着大概率丢失消息或信令,以及呼通率低的问题。
为此,本申请提供一种无线通信的方法,旨在降低丢寻呼的概率,提高呼通率。
本文的各申请实施例中,“用户”是逻辑概念,用户”可以对应(subscriber identity module,SIM)卡或签约用户信息或虚拟SIM卡或用户标识(如国际移动用户标识(international mobile subscriber identity,IMSI)/临时移动用户标识(temporary mobile subscriber identity,TMSI)),而不仅限于自然人用户或物理终端(手机)等。从网络侧的角度来看,不同的“用户”在逻辑上对应网络侧服务的不同的通信实体。例如,一个具有双注册功能的终端,对于网络侧来说,是两个通信实体。再例如,“用户”对应SIM卡或签约用户信息时,网络侧会将具有不同SIM卡或不同签约用户信息的两个终端识别为两个不同的通信实体,也会将具有多个不同SIM卡或多个签约用户信息的同一终端设备 识别为多个不同的通信实体,即使在实际上,具有多个不同SIM卡或多个签约用户信息的终端只是一个物理实体。
本申请实施例中,无线通信装置可以为终端,也可以为设置于终端内的芯片或电路系统等。所述电路系统例如可以为集成电路、逻辑电路。所述芯片例如可以是片上系统(system on a chip,SoC)芯片或者基带调制解调(modem)芯片。在上述无线通信装置为终端时,也可以称为用户设备(user equipment,UE)、接入终端、用户单元、用户站、移动站、移动台、远方站、远程终端、移动设备、用户终端、无线通信设备、用户代理或用户装置。
结合前面的描述,参见图3,图3为本申请提供的无线通信装置的结构示意图。如图3所示,无线通信装置300包括:处理模块310、基带模块320、收发模块330,以及存储模块340等。处理模块310主要用于对整个无线通信装置300进行控制、执行软件程序、处理软件程序的数据。基带模块320主要用于对通信协议以及通信数据进行处理,例如,信道编码、复用、调制、扩频等。
具体地,无线通信装置300可以将第一用户以及第二用户分别附着到网络中。可选地,基带模块320可以包括第一通信模块3201和第二通信模块3202。其中,第一通信模块3201可以获取第一用户的身份信息,建立与第一用户相关联的协议栈信息等。第一通信模块3201用于使能第一用户附着在第一网络,也即,使能终端以第一用户的身份附着到第一网络。第二通信模块3202可以获取第二用户的身份信息,建立与第二用户相关联的协议栈信息等。第二通信模块3202用于使能终端以第二用户的身份附着在第二网络。
如上文所述,第一网络和第二网络可以为同一个网络,或者,第一网络和第二网络也可以为不同的网络。例如,第一网络可以为5G网络,也可以为LTE网络。第二网络可以为5G网络,也可以为LTE网络。此外,第一网络和第二网络可以属于相同的运营商,或者分别属于不同的运营商,不作限定。
可选地,处理模块310和基带模块320可以是分别独立的模块,也可以合并为一个模块。在处理模块310和基带模块320合并为一个模块的情况下,合并后的模块同时具备处理模块310和基带模块320的功能。所述合并后的模块可以为一个独立的终端或者芯片等。
收发模块330同时具有发送和接收的功能。可选地,收发模块可以包括发送模块3301和接收模块3302。发送模块3301可以称为发射机、发射器、输出接口或者发射电路等。接收模块3302可以称为接收机、输入接口、接收电路等。
上述各个模块可以是通过软件代码实现的功能模块,也可以是硬件电路实现的功能模块,或软硬结合实现的功能模块,本申请实施例对此并不限定。
在本申请实施例中,无线通信装置300的第一通信模块3201,使能第一用户附着在第一网络之后,可以维持第一用户与第一网络的第一小区的RRC连接。或者说,第一用户在所述第一小区中处于连接态。无线通信装置300的第二通信模块3202,使能第二用户附着在第二网络之后,将第二用户驻留在第二网络的第二小区。
根据上文对于连接态和空闲态的说明,第一用户在第一小区处于连接态,第二用户驻留在第二小区处于空闲态。因此,无线通信装置300可以与第一小区进行数据的发送和/或接收等操作,例如,执行第二业务。同时,无线通信装置300可以监听第二小区发送的寻呼消息等信令。
本申请实施例,在无线通信装置接收到来自第二小区的寻呼消息的情况下,通过请求第一小区的第一网络设备释放第一用户与第一小区之间的第一RRC连接,再建立第二用户与第二小区之间的第二RRC连接,从而使得第二用户进入空闲态,第一用户进入连接态。第一用户进入连接态之后,可以执行寻呼消息指示的第一业务,例如,语音业务(例如,打电话)、短信业务等。
如上文所述,无线通信装置可以为终端或安装于终端内的芯片、电路系统等,下文以无线通信装置为终端作为示例进行说明。
在第一用户和第二用户处于上述状态的情况下,终端可以执行如图4所示的方法400。
参见图4,图4为本申请提供的无线通信的方法400的流程图。
410、终端接收来自第二小区的第二网络设备的寻呼消息,所述寻呼消息用于寻呼所述终端在第一网络处理第一业务。
例如,寻呼消息用于寻呼终端建立和第二小区的RRC连接,或者寻呼消息用于寻呼终端执行跟踪区域更新(tracking area update,TAU)等。
应理解,终端以第二用户的身份附着到第二网络,并保持和第一网络的第一小区的RRC连接。因此,对于第一网络的网络设备而言,寻呼消息用于寻呼终端在第一网络处理第一业务,也可以说,寻呼消息用于寻呼第二用户处理第一业务。
可选地,和第二业务相比较,第一业务的优先级更高。
420、终端向第一网络的第一网络设备发送请求消息,所述请求消息用于第一网络设备释放第一用户和第一小区之间的第一RRC连接。
430、终端释放第一RRC连接.
440、终端建立第二用户和第二小区之间的第二RRC连接。
可选地,第二用户和第二小区之间的第二RRC连接,即是,第二用户和第二小区第二网络设备之间的RRC连接。
可以理解的是,终端释放第一RRC连接之后,第一用户在第一小区进入空闲态。而终端建立第二用户和第二小区的RRC连接之后,第二用户从空闲态进入连接态。
450、终端在第二网络处理第一业务。
可选地,在步骤430之前,方法400可以包括步骤460。
460、终端接收来自第一网络设备的针对所述请求消息的响应消息,所述响应消息用于指示第一网络设备释放了第一RRC连接。
本申请的技术方案,第一用户在第一小区处于连接态,第二用户在第二小区处于空闲态的情况下,终端在接收到来自第二小区的寻呼消息,请求第二用户处理比第一用户的业务优先级更高的第一业务的情况下,终端向第一小区的网络设备发送请求消息,请求第一小区的网络设备释放第一用户和第一小区之间的RRC连接,使得网络设备获知第一用户的状态的变化。进一步地,终端释放第一用户和第一小区之间的RRC连接,并使能第二用户建立与第二小区的RRC连接,使第二用户从空闲态进入连接态,进而可以处理第一业务。
由于终端主动请求第一小区的网络设备释放第一用户的RRC连接,使得第一小区的网络设备获知第一用户的RRC连接的状态从连接态进入空闲态,可以避免终端直接释放第一用户的RRC连接,而网络设备对第一用户的RRC连接的状态的变化并未感知,仍然 “认为”第一用户处于连接态,在此基础上,如果第一小区的网络设备向第一用户发送消息和/或信令,将导致消息和/或信令的丢失,并且呼通率低。而本申请实施例,终端通过向第一小区的网络设备发送请求消息,使得第一小区的网络设备可以获知第一用户的RRC连接的状态变化,从而避免上述问题的出现,因此有助于降低消息和/或数据丢失的概率,提高呼通率。
换句话说,本申请实施例的方案,网络设备所感知到的用户的RRC连接的状态,与其实际的状态始终是保持一致的。
在具体实现中,终端使网络设备感知用户的RRC连接的状态变化的方式可以有多种。
在一个示例中,终端可以通过RRC连接重建立流程,使得网络设备获知用户的RRC连接从连接态切换为空闲态。
为了便于理解,首先结合图5和图6对RRC连接重建立流程进行介绍。
参见图5,图5为RRC连接重建立流程的一个示例。
510、UE处于连接态。
处于连接态的UE,在一些场景下向网络设备发起RRC连接重建请求。例如,由于UE和网络设备之间的无线链路异常或者其它异常,UE主动向网络设备发起RRC连接重建立请求,如520所述。
520、UE向网络设备发送RRC重建请求消息。
可选地,在不同的网络制式中,本申请实施例中各消息的名称可能有所不同。
例如,RRC重建立请求消息是5G中的消息名称,具体可以为RRC re-establish request message。在LTE中,RRC重建立请求消息可以替换为RRC连接重建立请求消息,具体可以为RRC connection re-establishment request message。
其中,RRC重建立请求消息中包括信元短消息完整性鉴权码(short message authentication code for integrity,shortMAC_I)。信元shortMAC_I用于在RRC连接重建立流程中对UE进行识别和验证。
网络设备接收来自UE的RRC重建立请求消息,并根据信元shortMAC_I对UE进行识别和验证。根据识别和验证的结果,网络设备向UE回复RRC重建立请求消息的响应消息。
530、网络设备向UE发送响应消息。其中,响应消息用于指示网络设备允许RRC连接重建立或者拒绝RRC连接重建立。
在530中,假设网络设备发送的响应消息指示允许RRC连接的重建立。同样地,在不同的网络制式中,针对RRC重建立请求消息的响应消息的名称也有所不同。例如,在5G中,该响应消息可以为RRC重建立消息,具体可以为RRC re-establishment message。而在LTE中,该响应消息为RRC连接重建立消息,具体可以为RRC connection re-establishment message。
UE接收来自网络设备的响应消息。
540、UE根据允许RRC重建立的响应消息进行配置。
550、UE在完成配置之后,向网络设备发送RRC重建立完成消息。
类似地,RRC重建立完成消息是在5G中的消息名称,具体可以为RRC re-establish complete message。而在LTE中,RRC重建立完成消息可以替换为RRC连接重建立完成 消息,具体可以为RRC connection re-establish complete message。
560、UE进入连接态。
在另一种可能的情况下,UE向网络设备发送的RRC重建立请求被网络设备拒绝。RRC重建立请求被拒绝的流程参见图6。
参见图6,图6为RRC连接重建立流程的另一个示例。
610、UE处于连接态。
620、UE向网络设备发送RRC重建请求消息。
630、网络设备向UE发送响应消息。其中,响应消息用于指示网络设备拒绝UE的RRC连接重建立请求。
具体地,网络设备根据RRC重建立请求消息中的信元shortMAC_I,对UE进行识别和验证。如果识别和验证失败,网络设备向UE发送RRC重建立拒绝消息。在5G中,该响应消息具体可以为RRC re-establishment reject message。在LTE中,该响应消息具体可以为RRC connection re-establishment reject message。
640、UE根据RRC重建立拒绝消息,释放RRC连接,进入空闲态。
作为一个实施例,在本申请的技术方案中,为了使网络设备感知到的用户的RRC连接的状态,与用户所处于的实际状态(连接态或空闲态)保持一致,无线通信装置可以借助于RRC连接重建立流程,将用户从连接态变化为空闲态通知网络设备,下面结合图7进行说明。
参见图7,图7为本申请提供的无线通信的方法的一个示例。
710、UE1处于连接态,UE2处于空闲态。
应理解,UE1表示一个用户,UE2表示另一个用户。
在图7的流程中,假设UE1和UE2附着到同一个网络。
具体地,无线通信装置可以使能UE1附着到网络,并保持UE1和该网络的第一小区的RRC连接。在一种场景下,无线通信装置保持和第一小区的RRC连接,并处理第二业务。此外,无线通信装置使能UE2附着到该网络,并驻留在该网络的第二小区,从而可以监听第二小区的寻呼消息等信令。
可选地,第二小区可以和第一小区是同一个小区,或者是该无线通信装置所附着的网络的不同小区,不作限定。
720、无线通信装置接收来自网络设备的寻呼消息。其中,寻呼消息用于寻呼无线通信装置处于第一业务。
和第二业务相比,第一业务的优先级更高,无线通信装置需要使能UE1从连接态进入空闲态,并使能UE2从空闲态进入连接态。
需要理解的是,这里并不关注更高优先级的第一业务具体为何种业务。而是说,和UE1正在处理的第二业务相比,第一业务的优先级更高。因此,UE2优先需要使用射频通道。
730、无线通信装置向网络设备发送RRC重建立请求消息。
其中,RRC重建立请求消息携带信元shortMAC_I,且shortMAC_I不能通过gNB的识别和验证。或者说,信元shortMAC_I用于网络设备释放UE1和第一小区之间的RRC连接。
需要注意的是,在本方案中,无线通信装置向网络设备发送RRC重建立请求消息,其目的在于借助于RRC连接重建立流程,使网络设备获知UE1从连接态到空闲态的状态变化。这样,在无线通信装置使能UE1从连接态进入空闲态之后,UE1的实际状态和网络设备所感知的UE1的状态是一致的。
因此,在730中,无线通信装置向网络设备发送的RRC重建立请求,需要达到被网络设备拒绝的目的。可以理解的是,如果是正常发起RRC连接重建立的场景,UE1需要根据UE1的源小区的安全配置构造信元shortMAC_I,以通过gNB的识别和验证,使得gNB允许UE1的RRC重建立请求。
具体地,shortMAC_I用于在RRC重建立流程中对UE进行识别和验证,shortMAC_I可以被设置为MAC_I的16个最低有效位(least significant bits,LSB),MAC_I根据源物理小区的安全配置计算。其中,安全配置可以包括源小区的无线网络临时标识(cell-radio network temporary identifier,C-RNTI)、源小区的物理标识(physical cell identifier,PCI)以及UE的上下文等信息。
应理解,在本申请实施例中,第一用户的源小区是指第一用户在发起RRC重建立流程之前的所接入的小区,具体地,在本文中,应为第一小区。
信元shortMAC_I的作用可以如下面的描述:
The IE shortMAC_I is used to identify and verify the UE at RRC connection re-establishemnt.The 16least significant bits of the MAC_I calculated using the security configuration of the source PCell,as specified in 5.3.7.4。
但是,在本申请实施例中,UE1需要构造“不能通过识别和验证的信元shortMAC_I”,以达到被网络设备拒绝RRC重建立请求的目的。因此,本申请实施例中,shortMAC_I的数值与第一数值不同,以使网络设备拒绝UE1和第一小区之间的RRC连接的重建立。从而,网络设备释放UE1和第一小区之间的RRC连接。在UE1从连接态进入空闲态之后,网络设备保存的UE1的状态和UE1实际的状态将会是一致的。
其中,第一数值为MAC_I的16个最低有效位。
基于上面的发明构思,无线通信装置“刻意”构造信元shortMAC_I,使得携带该信元“shortMAC_I”的RRC连接重建立请求消息无法通过gNB的识别和验证。
其中,信元shortMAC_I的结构,可以如第三代合作伙伴计划(the 3 rd generation partnership project,3GPP)协议38.331-f40的6.2.2中的描述:
Figure PCTCN2019127922-appb-000001
Figure PCTCN2019127922-appb-000002
另外,shortMAC_I的结构如38.331的6.3.2的描述,具体如下:
shortMAC_I information element
--ASNSTART
--TAG-SHORTMAC-I-START
shortMAC-I::=BIT STRING(SIZE(16))
--TAG-SHPRTMAC-I-STOP
--ASNSTOP
例如,根据UE1的源小区的安全配置,可以确定MAC_I的16个最低有效位(也即,第一数值)0000000000000001。为了起到“不能通过识别和验证”目的,终端向第一小区的网络设备发送的RRC重建立请求消息中携带的shortMAC_I需要构造为第一数值之外的其它数值。例如,0000000000000000。
可选地,在一个实施例中,UE1可以将信元shortMAC_I构造为随机值。将信元shortMAC_I构造为随机值,既可以起到该信元在本申请实施例中的作用,又易于实现,对于UE而言,复杂度低。
740、网络设备根据RRC重建立请求消息中携带的信元shortMAC_I,对UE1进行识别和验证。由于无线通信装置刻意构造的shortMAC_I数值,使得UE1无法通过识别和验证,因此,网络设备发送RRC重建立拒绝消息。
此外,网络设备释放UE1和第一小区的RRC连接。
无线通信装置接收来自网络设备的RRC重建立拒绝消息,例如具体可以为RRC re-establishment reject message。
750、无线通信装置释放UE1和第一小区的RRC连接。
此时,无线通信装置在第一小区从连接态进入空闲态,或者说,UE1在第一小区从连接态进入空闲态。
760、无线通信装置向第二小区的网络设备发送RRC连接请求消息,所述RRC连接 请求消息用于请求建立和第二小区的RRC连接。
其中,RRC连接请求消息在不同的网络制式中,其消息名称不同。例如,在5G中,RRC连接请求消息具体为RRC建立请求,可以为RRC setup request。而RRC连接请求消息是在LTE中的消息名称,具体可以为RRC connection request message。
之后,无线通信装置在第二小区从空闲态进入连接态,或者说,UE2在第二小区从空闲态进入连接态。
进一步地,无线通信装置与第二小区建立RRC连接之后,还可以包括步骤770。
770、无线通信装置在第一网络所述第一业务。
可见,图7所示的流程,无线通信装置通过构造不能通过识别和验证的shortMAC_I,主动触发RRC连接重建立拒绝流程,使得UE1从连接态进入空闲态的变化可以被UE1的网络设备获知。
以上图7中,以UE1和UE2附着在同一个网络为例,在UE1和UE2附着在不同的网络的架构中,方法也是类似的,下面结合图8举例说明。
参见图8,图8为本申请提供的无线通信的方法的另一个示例。
无线通信装置可以附着在第一网络,并维持与第一网络的第一小区的第一RRC连接。同时,无线通信装置可以附着在第二网络,并驻留在第二网络的第二小区,从而监听来自第二小区的无线信令。在此场景下,本申请实施例提供的无线通信的方法流程如下。
810、无线通信装置在第一网络的第一小区执行第二业务。
820、无线通信装置接收来自于第二网络的第二小区的网络设备的寻呼消息,所述寻呼消息用于寻呼所述无线通信装置在第二网络执行第一业务。
可选地,第一业务的优先级可以高于第二业务的优先级。
830、无线通信装置向第一小区的第一网络设备发送RRC重建立请求消息,所述RRC重建立请求消息中携带信元shortMAC_I。其中,所述shortMAC_I是随机构造的。
840、第一小区的第一网络设备接收所述RRC重建立请求消息,根据随机构造的信元shortMAC_I,发送RRC重建立拒绝消息。
850、无线通信装置在所述第一小区进入空闲态。
860、无线通信装置向第二小区的网络设备发送RRC建立请求消息,所述RRC建立请求消息用于请求建立与所述第二小区的RRC连接。
可选地,RRC建立请求消息具体可以为RRC setup request message。
UE2和第二小区建立RRC连接之后,UE2在第二小区从空闲态进入连接态,UE1在第一小区从连接态进入空闲态。或者说,UE1让出了射频发射通道供UE2使用。
进一步地,无线通信装置建立与第二小区的RRC连接之后,可以处理更高优先级的所述第一业务。
以上对本申请提供的无线通信的方法进行了详细说明。下面介绍本申请提供的无线通信装置。
