- the connection request is used by the terminal device to restore the connection with the second RAN network element, including initiating a random access procedure to the second RAN network element.
- the second RAN network element After the terminal device resumes the connection with the second RAN network element, the second RAN network element sends the activation indication information to the first RAN network element.
- the activation indication information is used to notify the first RAN network element, and the terminal device has restored the connection of the second RAN network element.
- a method for establishing a connection is provided in the embodiment of the present application.
- the terminal device in the deactivated state performs cell measurement according to the measurement configuration information of the primary RAN network element after restoring the connection of the primary RAN network element.
- the primary RAN network element allocates a new secondary RAN network element to the terminal device according to the result of the cell measurement, and configures the information of the new secondary RAN network element.
- the entire recovery connection process is cumbersome and time consuming, resulting in inefficient network transmission.
- the configuration information of the primary cell and the configuration information of the secondary cell are saved.
- the connection with the original RAN network element may be restored according to the configuration information of the secondary cell. It can be seen that the application simplifies the steps of restoring the connection of the terminal device, speeds up the process of restoring the connection of the terminal device, and improves the efficiency of network transmission.
- step 101 of the embodiment of the present application the step of determining whether the terminal device has no data transmission in a preset time period is further elaborated.
- the data transmission between the terminal device and the RAN network element mainly includes the following two situations, as follows:
- the primary RAN network element can directly determine whether the terminal device has no data transmission within a preset time according to its own data transmission condition. If the primary RAN network element transmits the data of the terminal device within a preset time, it is determined that the terminal device has data transmission within a preset time; if the primary RAN network element has not transmitted the data of the terminal device within a preset time, then It is determined that the terminal device has no data transmission for a preset time.
- the bearer type of the terminal device includes the secondary cell bearer or the secondary cell shared bearer.
- the primary RAN network element can only determine whether the terminal device has no data transmission within a preset time according to its own data transmission situation, and also needs to determine the data transmission situation of the secondary RAN network element. As shown in FIG. 4, the determining method specifically includes the following steps:
- the primary RAN network element sends inactivity time configuration information to the secondary RAN network element.
- the inactivity time configuration information is used to notify the secondary RAN network element whether the terminal device has no data transmission in the time period.
- the inactivity time configuration information includes a length of the specified time period, and/or a reporting period of performing an inactivity notification, and/or a number of reporting of the inactive status notification.
- the secondary RAN network element After receiving the inactivity time configuration information sent by the primary RAN network element, the secondary RAN network element determines whether the terminal device has data transmission within a preset time, and reports the status notification of the terminal device.
- the status notification of the terminal device includes at least one of an activity status notification and an inactivity status notification.
- the terminal device if the secondary RAN network element determines that the terminal device has no data transmission for a preset time, the terminal device notifies the inactive state notification of the terminal device to the primary RAN network element; or, if the secondary RAN network element determines that the terminal device is at the preset time If there is data transmission, the active status notification is reported to the primary RAN network element.
- the inactive state notification is reported to the primary RAN network element, and the secondary RAN network element is the terminal before the suspension indication of the primary RAN network element is received or the indication is released.
- the device transmits data, and the secondary RAN network element needs to send an activity status notification to the primary RAN network element.
- a preset reporting period may be configured. After the secondary RAN network element reports the inactivity status notification to the primary RAN network element, the timer can be started, and the timing duration is a preset reporting period, so that the secondary RAN network element periodically reports the status notification of the terminal device to the primary RAN network element.
- the network resource is wasted in order to prevent the secondary RAN network element from continuously reporting the inactivity status notification of the terminal device.
- the threshold of the number of times of reporting the inactive status notification may be configured, that is, the number of times the secondary RAN network element reports the inactive status notification reaches the threshold of the number of reported times, and the inactivity status notification may not be continued.
- the secondary RAN network element may actively report the inactivity status notification to the primary RAN network element. If the time threshold of the inactive state is set, when the secondary RAN network element determines that the inactivity time of the terminal device reaches the time threshold, the inactive state notification of the terminal device is reported to the primary RAN network element.
- the primary RAN network element receives the status notification of the terminal device sent by the secondary RAN network element, and determines, according to the status notification of the terminal device and the data transmission status of the terminal device, whether the terminal device has no data transmission for a preset time.
- the primary RAN network element may directly determine that the terminal device has data transmission within a preset time, and determine to maintain the connection state of the terminal device.
- the primary RAN network element receives the inactivity status notification of the terminal device sent by the secondary RAN network element, it needs to be further determined according to the data transmission status of the primary RAN network element itself. Specifically, if the primary RAN network element transmits the data of the terminal device within a preset time, it is determined that the terminal device has data transmission within a preset time, and determines to maintain the connection state of the terminal device; if the primary RAN network element is preset If the data of the terminal device is not transmitted in the time, it is determined that the terminal device has no data transmission for a preset time, and it is determined that the control terminal device enters the deactivated state from the connected state.
- the embodiment of the present application further provides a method for establishing a connection, as shown in FIG. 5, which specifically includes:
- the primary RAN network element sends a connection suspension indication to the terminal device.
- connection suspension indication is used to indicate that the terminal device enters the deactivated state from the connected state, and may be, for example, a connection suspension request message, a connection release request, or a connection deactivation request.
- the primary RAN network element may also configure measurement control information, that is, measurement configuration information, for the terminal device, where the measurement configuration information includes a measurement object, and may be used by the terminal device to perform cell measurement during subsequent connection recovery.
- the measurement configuration information may also include information of the camped cell, information of the measurement object, and a mapping relationship between the camped cell and the measurement object, as shown in the following table. For example, if the camping cell is the cell 1, the measurement object corresponding to the camping cell is the frequency point F1. If the camping cell is the cell 5, the measurement object corresponding to the camping cell is the frequency point F6, or the cell 1, and so on.
- the measurement configuration information may further include a measurement identifier, where the measurement identifier may be used to identify a result of the cell measurement corresponding to the measurement configuration information reported by the subsequent terminal device.
- the terminal device After receiving the connection suspension indication, the terminal device acquires the measurement configuration information, and determines the object to be measured according to the current camping cell information of the terminal device.
- the terminal device determines the object to be measured according to the camped cell. If the measurement configuration information includes the identifier of the measurement object, it may be determined that the measurement object is the object to be measured.

Description
本申请要求于2017年7月11日提交中国专利局、申请号为201710562453.7、申请名称为“一种连接建立的方法、装置及系统”的中国专利申请的优先权,其全部内容通过引用结合在本申请中。
本申请涉及通信技术领域,尤其涉及一种连接建立的方法、装置及系统。.
由于单个基站的带宽资源和覆盖范围有限,因此,集中多个小区或者基站的无线资源来为用户提供服务,更易于满足用户的容量需求和覆盖要求,这种方式通常称之为多连接,例如双连接。在双连接模式下,一个终端设备可同时与两个无线接入网(Radio Access Network,RAN)网元连接,并进行数据传输。其中一个RAN网元为主RAN网元,其包含的小区为主小区组(Master Cell Group,MCG),主RAN网元控制终端设备的安全参数的生成,以及维护和核心网之间的控制面连接。另一个RAN网元为辅RAN网元,其包含的小区为辅小区组(Secondary Cell Group,SCG)。主RAN网元可独立传输用户面数据,辅RAN网元也可独立传输用户面数据,主RAN网元也可以与辅RAN网元分担传输用户面数据。需要说明的是,辅RAN网元和核心网之间没有控制面连接,数据面连接为可选的连接。如图1所示,终端设备10通过RAN11和RAN12与核心网设备12进行数据传输,其中,RAN11为主RAN网元,RAN12为辅RAN网元。
目前,若处于双连接模式下的终端设备在一定时间内没有数据传输,则主RAN网元会向该终端设备发送挂起指示,控制该终端设备由连接态进入去激活(inactive)态,并释放终端设备与辅RAN网元的连接。若终端设备再有数据需要传输,则需要恢复与RAN网元的连接。具体的,终端设备需向当前的驻留小区发送连接恢复请求,则当前小区作为主小区,当前驻留小区所对应的RAN网元作为新的主RAN网元,为该终端设备建立新的连接。新的连接建立后,主RAN网元向终端设备配置测量信息,以便终端设备进行测量。终端设备将测量结果反馈给主RAN网元后,主RAN网元根据测量结果为该终端设备选择新的辅RAN网元,并为该终端设备添加新的SCG的配置信息。终端设备根据给配置信息建立与新的辅RAN网元的连接,然后便可以和核心网设备进行数据传输了。可见,终端设备恢复与辅RAN网元的连接的步骤繁琐,进而信令多、延迟大,造成网络传输效率低下。
发明内容
本申请实施例提供一种连接建立的方法、装置及系统,能够解决处于去激活态的终端设备在恢复与辅RAN网元的连接的步骤繁琐、延迟大,造成网络传输效率低下的问题。
为达到上述目的,本申请的实施例采用如下技术方案:
第一方面,提供一种连接建立的方法,具体包括:终端设备向第一无线接入网RAN 网元发送连接恢复请求信息。其中,第一RAN网元为该终端设备当前驻留的小区所对应的RAN网元,且第一RAN网元为终端设备在连接态时使用的主小区的配置信息指示的RAN网元。此时,终端设备处于去激活态,该终端设备存有配置信息,该配置信息包括终端设备在连接态时使用的辅小区的配置信息。终端设备接收第一RAN网元发送确认信息,该确认信息响应于连接恢复请求信息。终端设备根据确认信息恢复与第二RAN网元的连接,这里的第二RAN网元为所述辅小区的配置信息指示的RAN网元。
其中,连接恢复请求信息用于指示终端设备由去激活态重新进入连接态,这个过程也可称为恢复连接,或激活,或重激活。连接恢复请求信息可携带在连接恢复请求、或者连接激活请求、或者连接重激活请求等消息中。辅小区配置信息包含辅小区的标识和频点信息等,可用于终端设备与辅RAN网元的连接。其中,辅小区可以是载波聚合的辅小区,也可以是双连接中的MCG中的辅小区,以及SCG中主辅小区和其他辅小区。
可见,本申请实施例中,当终端设备确定需要传输数据时,可根据配置信息恢复与原RAN网元的连接。由此简化了终端设备恢复连接的步骤,加快了终端设备恢复连接的过程,提高了网络传输的效率。
在一种可能的设计中,若接收到第一RAN网元发送确认信息中包含指示该终端设备保持辅小区配置的信息,那么终端设备直接确定恢复与第二RAN网元的连接。若接收到第一RAN网元发送的针对连接恢复请求信息的确认信息中没有包含指示该终端设备保持辅小区配置的信息,那么,终端设备根据保存的主小区的配置信息判断第一RAN网元是否为终端设备在连接态时使用的主小区,若是,则终端设备也能确定恢复与第二RAN网元的连接。由此,提供了接收到的第一RAN网元发送的针对连接恢复请求信息的确认信息的两种实现方式。
在一种可能的设计中,当终端设备确定需要向第一RAN网元发送连接恢复请求信息后,并且终端设备根据所述主小区的配置信息确定终端设备当前驻留的小区与主小区为同一个小区,则终端设备对所述辅小区中至少一个小区进行测量,可以优先对主辅小区进行测量。这是因为终端设备若在连接态时使用的主小区请求恢复连接,那么能够成功恢复与连接态时使用的辅小区的连接的几率也较大。因此,提前对连接态时使用的辅小区进行测量,可以加快恢复与连接态时使用的辅小区的连接的过程。
在一种可能的设计中,若终端设备确定辅小区中至少一个小区可用,则终端设备根据所述辅小区的配置信息恢复与所述第二RAN网元的连接;或者,若终端设备确定辅小区中至少一个小区不可用,则所述终端设备向所述第一RAN网元发送连接恢复失败的信息。
在一种可能的设计中,若终端设备检测到连接态时使用的辅小区中至少一个小区,则确定连接态时使用的辅小区可用;若终端设备没有检测到辅小区中至少一个小区,则确定连接态时使用的辅小区不可用。
或者,若终端设备检测到连接态时使用的辅小区中至少一个小区,且检测到的小区的信号测量值大于或等于门限阈值,则终端设备确定连接态时使用的辅小区可用;若终端设备检测到连接态时使用的辅小区中至少一个小区,但检测到的小区的信号测 量值小于门限阈值,则终端设备确定连接态时使用的辅小区不可用。
其中,该门限阈值可以是预定义的值,也可是第一RAN网元根据网络情况或终端设备的业务类型动态配置的数值。该门限阈值也可以是携带第一RAN网元发送的连接挂起指示中,或者携带在第一RAN网元向终端设备发送的确认消息中。
第二方面,提供一种连接建立的方法,包括:第一无线接入网RAN网元接收到终端设备发送的连接恢复请求信息,该连接恢复请求信息包括所述终端设备的标识;那么,第一RAN网元根据终端设备标识获取该终端设备在连接态下使用的辅小区的配置信息;并向终端设备发送确认信息,该确认信息响应于连接恢复请求信息,用于指示终端设备恢复与第二RAN网元的连接,其中,第二RAN网元为所述辅小区的配置信息指示的RAN网元。
在一种可能的设计中,确认信息还包括指示终端设备保持辅小区配置的信息。
在一种可能的设计中,第一RAN接收第二RAN网元发送的激活指示信息,激活指示信息用于通知终端设备已恢复与第二RAN网元的连接。
在一种可能的设计中,在第一RAN网元接收到终端设备发送的连接恢复请求信息之前,若第一RAN网元确定终端设备在预设时间段内没有数据传输,则指示该终端设备进入去激活。
在一种可能的设计中,第一RAN网元向第二RAN网元发送不活动时间配置信息,其中,该不活动时间配置信息用于通知第二RAN网元上报终端设备的在预设时间段内的状态通知;终端设备的状态通知用于通知第一RAN网元终端设备在预设时间段内数据传输的情况,终端设备的状态通知包括活动状态通知和不活动状态通知中至少一个;那么,第一RAN网元根据第二RAN网元上报的终端设备的状态通知确定终端设备在所述预设时间段内没有数据传输。
若第一RAN网元接收到第二RAN网元上报的终端设备的活动状态通知,则第一RAN网元确定终端设备在预设时间段内有数据传输。若第一RAN网元接收到第二RAN网元上报的不活动状态通知,则还需要根据自身的数据传输情况进行判断终端设备是否在预设时间段内没有数据传输。
其中,不活动时间配置信息包括指定时间段的长度,和/或进行不活动状态通知的上报周期,和/或不活动状态通知的上报次数。
第三方面,提供一种连接建立的方法,包括:终端设备获取测量配置信息,并根据终端设备当前的驻留小区的信息确定待测量对象,此时,终端设备处于去激活态;终端设备对待测量对象进行小区测量,并向第一RAN网元发送小区测量的结果,其中,第一RAN网元为所述终端设备当前的驻留小区所对应的RAN网元;终端设备接收第一RAN网元发送的辅小区的配置信息;终端设备根据所述辅小区的配置信息与第二RAN网元建立连接,其中,所述辅小区的配置信息为所述第一RAN网元根据所述小区测量的结果确定的,第二RAN网元为所述辅小区的配置信息指示的RAN网元。
可见,处于去激活态的终端设备可根据当前的驻留小区确定待测量对象,提前对待测量对象进行小区测量,而后当前的驻留小区对应的RAN网元可根据该小区测量的结果为终端设备确定辅小区的配置信息。这样,有利于加快终端设备连接恢复的过程,有利于提高网络的传输效率。
在一种可能的设计中,终端设备接收第三RAN网元发送的测量配置信息,其中,第三RAN网元为终端设备由连接态进入去激活态时所在的RAN网元,测量配置信息包括驻留小区的信息、测量对象的信息以及驻留小区与所述测量对象的映射关系。

下面将结合本申请实施例中的附图,对本申请实施例中的技术方案进行清楚地描述。
本申请技术方案可以应用于第二代(2th Generation,2G)通信网络、第三代(3th Generation,3G)通信网络、第四代(4th Generation,4G)通信网络、第五代(5th Generation,5G)通信网络以及后续演进网络中。
请参见图1,图1是本申请实施例提供的一种通信网络的网络架构示意图。其中,如图1所示,该通信网络包括至少一个终端设备10、主RAN网元11、至少一个辅RAN网元12以及核心网网元13。
终端设备可以为手机、平板电脑、笔记本电脑、UMPC(Ultra-mobile Personal Computer,超级移动个人计算机)、上网本、PDA(Personal Digital Assistant,个人数字助理)等终端设备,如图1中只示出了一个终端设备10,但本领域技术人员可知,终端设备10的数目不限于一个。
网元即网络元件。RAN网元即接入网中承担小区内终端设备的接入功能的元件。RAN网元(包括:主RAN网元和辅RAN网元)可以对应不同的设备,例如:在2G通信网络中,RAN网元对应于基站和基站控制器。在3G通信网络中,RAN网元对应于基站和无线网络控制器(Radio Network Controller,RNC)。在4G通信网络中,RAN网元对应于演进型节点B(Evolved Node B,eNB)。在5G通信网络中,RAN网元对应于第五代的接入网设备。
核心网是通信网络的主要部分,它下联各个接入网,负责各接入网接入的业务的通信和管理。核心网网元13即承担通信网络的管理功能的节点。其也可以对应不同的设备,例如:在3G通信网络中,核心网网元13对应于服务通用分组无线服务支持节点(Serving GPRS Support Node,SGSN)或网关通用分组无线服务支持节点(Gateway GPRS Support Node,GGSN)。在4G通信网络中,核心网网元对应于移动管理节点功能(Mobility Management Entity,MME)或服务网关(Serving GateWay,S-GW)。在5G通信网络中,核心网网元对应于第五代的核心网网元设备,比如包括接入与移动性管理功能(Access and Mobility Management Function,AMF)和用户面功能(User Plane Function,UPF)。
需要说明的是,主RAN网元和辅RAN网元可以是采用相同的接入技术,也可采用不同的接入技术。另外,图1中仅示出了一个终端设备、两个RAN网元以及一个核心网网元,但本申请实施例不限制终端设备、RAN网元、核心网网元的数量以及网元之间的具体连接方式。
在图1中,终端设备10处于多连接模式。多连接模式即终端设备同时与多个接入网网元保持连接的模式。在多个接入网网元中,一个接入网网元是主接入网网元,其余接入网是辅接入网网元。这里以双连接模式进行说明。双连接模式即一个接入网网元是主接入网网元、另一个接入网是辅接入网网元的连接模式。在双连接模式中,如图1所示,终端设备10同时与主RAN网元11和一个辅RAN网元12连接。通常,主RAN网元可根据网络的负荷和终端设备的业务属性为终端设备配置不同的承载类型,以进行业务数据的传输。其中,主RAN网元为终端设备配置的承载类型主要有四类,分别为:一、主小区承载(MCG bear),是指业务数据从核心网发送给主RAN网元,由主RAN网元发送给终端设备。二、分担承载(split bear),是指业务数据从核心网发送给主RAN网元,由主RAN网元和辅RAN网元发送给终端设备。三、辅小区承载(SCG bear),是指业务数据从核心网发送给辅RAN网元,由辅RAN网元发送给终端设备。四、辅小区分担承载(SCG split bear),是指业务数据从核心网发送给辅RAN网元,由辅RAN网元和主RAN网元发送给终端设备。

下面结合图2对手机200的各个构成部件进行具体的介绍:

输入单元240可用于接收输入的数字或字符信息,以及产生与手机200的用户设置以及功能控制有关的键信号输入。具体地,输入单元240可包括触摸屏141以及其他输入设备142。触摸屏141,也称为触控面板,可收集用户在其上或附近的触摸操作(比如用户使用手指、触笔等任何适合的物体或附件在触摸屏141上或在触摸屏141附近的操作),并根据预先设定的程式驱动相应的连接装置。可选的,触摸屏141可包括触摸检测装置和触摸控制器两个部分。其中,触摸检测装置检测用户的触摸方位,并检测触摸操作带来的信号,将信号传送给触摸控制器;触摸控制器从触摸检测装置上接收触摸信息,并将它转换成触点坐标,再送给处理器280,并能接收处理器280发来的命令并加以执行。此外,可以采用电阻式、电容式、红外线以及表面声波等多种类型实现触摸屏141。除了触摸屏141,输入单元240还可以包括其他输入设备142。具体地,其他输入设备142可以包括但不限于物理键盘、功能键(比如音量控制按键、电源开关按键等)、轨迹球、鼠标、操作杆等中的一种或多种。

手机200还包括传感器260,包括:加速度传感器、陀螺仪、磁力计等。此外,手机200还可配置的重力传感器(gravity sensor)、气压计、湿度计、温度计、红外线传感器等其他传感器,在此不再赘述。

在如图1所示的通信网络中,在终端设备10的这种双连接模式下,若终端设备10在预设时间内一直没有数据传输,则主RAN会控制终端设备10由连接态处于去激活态,并为终端设备10分配相应的上下文信息和管理区域信息。而终端设备10处于去激活态时,若终端设备10在管理区域内移动而没有数据需要传输时,则不用通知主RAN网元,这样,有利于节省网络资源。而在终端设备10处于去激活态时,此时若有数据需要传输,则需要恢复终端设备10与主RAN网元和辅RAN网元的连接。具体的,终端设备10先与主RAN网元恢复连接,再根据主RAN网元确定的测量配置信息进行小区测量,并向主RAN网元反馈测量结果。这样,主RAN网元可根据反馈的测量结果为终端设备10选择新的辅RAN网元,并为终端设备10添加新的辅小区的配置信息。终端设备10便可根据新的辅小区的配置信息与新的辅RAN网元建立连接。显然,终端设备10在恢复连接的过程中,恢复与辅RAN网元的连接的步骤相对繁琐和耗时,会造成网络传输的延迟大、效率低下的问题。因此,可以采用本申请实施例提供的方法来缩短终端设备10与辅RAN网元的连接的时间,提高网络传输效率。
为此,本申请实施例提供一种连接建立的方法,可应用于如图1所示的通信网络中,如图3所示,该方法包括:
101、第一RAN网元确定终端设备在预设时间段内是否一直没有数据传输。
其中,第一RAN网元为该终端设备的主小区所在的RAN网元。主小区为终端设备提供安全参数输入的小区,确定终端设备的非接入层的参数,这些参数可用于终端设备与主RAN网元进行连接。其中,预设时间可为预定义的时间,例如可以是10秒。预设时间也可这样设置,通过统计终端设备之前的数据传输情况,得到两次数据传输 之间的平均间隔时间,或者是同一时间段内两次数据传输之间的平均间隔时间,将预设时间设置为平均间隔时间的特定倍数。本申请实施例对预设时间的具体设置。
具体的,若第一RAN网元确定终端设备在预设时间内一直没有传输数据,则可控制终端设备由连接态进入去激活态,即执行步骤102。若第一RAN网元确定终端设备在预设时间内传输了数据,则确定保持终端设备的连接态。
需要说明的是,针对终端设备与RAN网元之间的数据传输情况,例如:终端设备的承载类型,第一RAN网元可采用相应的确定方法去确定终端设备在预设时间内是否一直没有数据传输,具体的确定方法可参考下文的阐述。
可选的,也可由终端设备直接确定在预设时间内是否一直没有数据传输,若确定一直没有数据传输,将该信息上报给第一RAN网元。
102、若第一RAN网元确定终端设备在预设时间内一直没有数据传输,则分别向第二RAN网元和终端设备发送连接挂起指示。
其中,第二RAN网元为该终端设备的辅RAN网元,辅RAN网元包括的小区为SCG,SCG又包括一个主辅小区,以及可选的进一步包含至少一个次辅小区。连接挂起指示是用于指示终端设备由连接态进入去激活状态的,例如可以是连接挂起请求消息,连接释放请求,或者连接去激活请求。
103、终端设备接收到第一RAN网元的连接挂起指示后,保存终端设备在连接态时的配置信息。
其中,配置信息包括终端设备在连接态时使用的主小区的配置信息和辅小区的配置信息。主小区的配置信息包含至少包含主小区的标识和频点信息等,主小区的配置信息可用于终端设备与主RAN网元进行连接。辅小区配置信息包含辅小区的标识和频点信息等,辅小区的配置信息可用于终端设备与辅RAN网元的连接。其中,辅小区可以包括载波聚合的辅小区,也可以是双连接中的MCG中的辅小区,以及SCG中主辅小区和其他辅小区。
具体的,终端设备在收到第一RAN网元发送的挂起指示后,会进入去激活状态。需要注意的是,在现有技术中,此时终端设备通常释放与辅小区的连接,删除本地保存辅小区的配置信息。而在本申请实施例中,终端设备会保存终端设备的辅小区的配置信息,以便后续在恢复连接的过程中直接使用主小区和辅小区的配置信息。终端设备可在本地保存主小区和辅小区的配置信息,可以保存在第三方设备上,在需要使用时直接调取过来即可。
需要说明的是,第二RAN网元接收到第一RAN网元发送的连接挂起指示后,会释放与终端设备之间的连接,图中以103b示出。
104、当终端设备确定需要传输数据时,向第一RAN网元发送连接恢复请求信息。
其中,第一RAN网元为终端设备当前的驻留小区所对应的RAN网元,即第一RAN网元允许处于去激活态的终端设备通过当前的驻留小区接入核心网。并且,这里的第一RAN网元为终端设备在连接态时使用的主小区的配置信息所指示的RAN网元,换句话来说,终端设备是在原来的主小区请求连接恢复的。
其中,连接恢复请求信息用于指示终端设备由去激活态重新进入连接态,这个过程也可称为resume,或激活,或重激活。连接恢复请求信息可携带在连接恢复请求、 或者连接激活请求、或者连接重激活请求等消息中。
具体的,若终端设备接收到寻呼消息,或者终端设备确定有上行数据需要传输,则终端设备确定需要传输数据。那么,终端设备会向当前的驻留小区发起连接恢复请求。由于此时的驻留小区和连接态时使用的主小区为同一个小区,则可认为终端设备处于去激活态与上一次处于连接态时的位置未较大变化,那么终端设备当前位置的各个小区情况也大致相同,因此可采用终端设备上一次使用的辅小区作为现在的辅小区,即仍然可使用连接态时使用的小区的配置信息,与该辅小区的配置信息指示的第二RAN网元进行连接,那么,执行步骤105。否则,终端设备没有在处于连接态时使用的主小区,则认为终端设备的位置发生了较大的变化,终端设备当前驻留小区所对应的RAN网元为所述终端设备选择新的主RAN网元,主RAN网元发生了变化,那么相应的,不能再继续采用之前的辅RAN网元,需由新的主RAN网元为该终端设备重新选择新的辅RAN网元,确定新的SCG的配置信息。
可选的,在终端设备确定需要进行连接恢复后,或者向第一RAN发送连接恢复请求信息之后,若终端设备确定当前的驻留小区与终端设备在连接态时使用的主小区为同一个小区,则终端设备可启动对该终端设备在连接态使用的至少一个辅小区的测量,可以优先对主辅小区进行测量。这是因为终端设备若在连接态时使用的主小区请求恢复请求,那么能够成功恢复与连接态时使用的辅小区的连接的几率也较大。因此,提前对连接态时使用的辅小区进行测量,可以加快恢复与连接态时使用的辅小区的连接的过程。
需要说明的是,终端设备也可在接收到针对连接恢复请求信息的确认消息时,即步骤106,启动小区测量。本申请实施例并不限定启动小区测量的具体时间点。可选的,在小区测量结束后,将小区测量的结果上报给第一RAN网元,以便第一RAN网元根据该小区测量的结果确定测量的小区是否可用。
105、第一RAN网元接收到终端设备的连接恢复请求信息,向终端设备发送确认消息。
可选的,连接恢复请求信息中还携带有终端设备的标识。那么,第一RAN网元在接收到终端设备的连接恢复请求信息后,先根据连接恢复信息中的终端设备的标识确定本地存储的该终端设备的上下文信息,并从该终端设备的上下文信息中确定该终端设备在连接态时使用的主小区。进一步的,判断该终端设备此时接入的小区和连接态时使用的主小区是否为同一小区。若为同一小区,则第一RAN网元向终端设备发送确认消息,用于指示终端设备保持连接态使用的辅小区的配置。
可选的,在针对终端设备的连接恢复请求信息的确认消息中还可携带门限阈值。若终端设备对小区的进行测量后得到信号测量值大于或等于该门限阈值,表示该小区可以支持终端设备进行数据传输。若得到的信号测量值小于该门限阈值,表示该小区不可支持终端设备进行数据传输,即该小区不能作为该终端设备恢复到连接态时使用的辅小区。该门限阈值可以是预定义的值,也可是第一RAN网元根据网络情况或终端设备的业务类型动态配置的数值。需要说明是,该门限阈值也可以是携带第一RAN网元发送的连接挂起指示中,或者携带在第一RAN网元向终端设备发送的针对与连接挂起指示的确认消息中,本申请实施例对终端设备获取门限阈值的方式不做限定。
106、终端设备接收到第一RAN网元发送的针对该连接恢复请求的确认消息。
具体的,终端设备根据本地保存的主小区的配置信息判断终端设备当前的驻留小区和该终端设备在连接态时使用的主小区是否为同一小区,若是,则执行107;或者,确认消息中包括终端设备保持辅小区配置的消息,则直接执行107。
107、终端设备确定是否可恢复与第二RAN网元的连接。
其中,第二RAN网元为终端设备在连接态时使用的辅小区的配置信息指示的RAN网元,即终端设备确定能够恢复终端设备在连接态时使用的辅小区的连接。若终端设备第一RAN网元为终端设备在连接态时使用的辅小区所在的RAN网元是同一个RAN网元,则终端设备确定可恢复与第二RAN网元的连接。需要注意的是,第一RAN网元和第二RAN网元可以为同一RAN网元或者不同的RAN网元。
具体的,参考步骤104所述,若终端设备进行小区测量时,确定终端设备在连接态时使用的辅小区仍可用,则确定可恢复终端设备在连接态时使用的辅小区的连接,然后,执行步骤109。若确定终端设备在连接态时使用的辅小区不可用,则确定终端设备在连接态时使用的辅小区的不可用,执行步骤108。
可选的,确定终端设备在连接态时使用的辅小区是否可用,包括终端设备还确定了门限阈值,如果小区测量的辅小区的信号测量值大于或等于该门限阈值,则确定终端设备在连接态时使用的辅小区可用。若终端设备进行小区测量时,没有检测到终端设备在连接态时使用的辅小区,或者辅小区的信号测量值小于门限阈值,则确定终端设备保存的终端设备在连接态时使用的辅小区不可用。
108、终端设备需要向第一RAN网元发送连接恢复失败的信息。
可选的,连接恢复失败信息还可携带终端设备的测量结果。其中,测量结果可以是对终端设备在连接态时使用过的至少一个辅小区进行小区测量的结果,也可以是对终端设备在连接态时使用过的主小区的进行对同频或者异频邻区的小区测量的结果。
109、终端设备向第二RAN网元发送连接请求。
其中,连接请求用于终端设备恢复与第二RAN网元的连接,包括向第二RAN网元发起随机接入过程。
110、在终端设备恢复与第二RAN网元的连接后,第二RAN网元向第一RAN网元发送激活指示信息。
其中,该激活指示信息用于通知第一RAN网元,终端设备已恢复第二RAN网元的连接。
本申请实施例提供的一种连接建立的方法,相比较于现有技术中,处于去激活态的终端设备在恢复主RAN网元连接后,根据主RAN网元的测量配置信息进行小区测量。主RAN网元再根据小区测量的结果为终端设备分配新的辅RAN网元,配置新的辅RAN网元的信息,整个恢复连接的过程繁琐、耗时,造成网络传输效率低下。而本申请中,终端设备在进入去激活态时,保存主小区的配置信息和辅小区的配置信息。当终端设备确定需要传输数据时,可根据辅小区的配置信息恢复与原RAN网元的连接。可见,本申请简化了终端设备恢复连接的步骤,加快了终端设备恢复连接的过程,提高了网络传输的效率。
为了更好的理解本申请实施例,对本申请实施例中步骤101中,确定终端设备在 预设时间内是否一直没有数据传输的步骤进行进一步详细阐述。
终端设备与RAN网元之间的数据传输情况主要包括以下两种情况,如下:
第一种情况:终端设备和核心网网元之间的所有的数据都经过主RAN网元,例如:终端设备的承载类型只包括主小区承载或主小区分担承载。那么,主RAN网元直接根据自身的数据传输情况便可确定终端设备在预设时间内是否一直没有数据传输。若主RAN网元在预设时间内传输了终端设备的数据,则确定该终端设备在预设时间内有数据传输;若主RAN网元在预设时间内一直没有传输终端设备的数据,则确定终端设备在预设时间内一直没有数据传输。
第二种情况:终端设备和核心网网元之间有部分数据没有经过主RAN网元,例如:终端设备的承载类型包括辅小区承载或辅小区分担承载。那么,主RAN网元仅仅根据自身的数据传输情况并不能确定终端设备在预设时间内是否一直没有数据传输,还需要结合辅RAN网元的数据传输情况进行确定。如图4所示,该确定方法具体包括如下步骤:
201、主RAN网元向辅RAN网元发送不活动时间配置信息。
其中,不活动时间配置信息用于通知辅RAN网元确定终端设备在时间段内是否一直没有数据传输。可选的,不活动时间配置信息包括指定时间段的长度,和/或进行不活动状态通知的上报周期,和/或不活动状态通知的上报次数。
202、辅RAN网元接收到主RAN网元发送的不活动时间配置信息后,判断终端设备在预设时间内是否有数据传输,并上报终端设备的状态通知。
其中,终端设备的状态通知包括活动状态通知和不活动状态通知中的至少一个。
具体的,若辅RAN网元确定终端设备在预设时间内一直没有数据传输,则向主RAN网元上报终端设备的不活动状态通知;或者,若辅RAN网元确定终端设备在预设时间内有数据传输,则向主RAN网元上报活动状态通知。
需要说明的是,在辅RAN网元在向主RAN网元上报了不活动状态通知,在没有接收到主RAN网元的挂起指示时或者释放指示之前,若辅RAN网元又为该终端设备传输了数据,则辅RAN网元需要向主RAN网元发送活动状态通知。
可选的,为了能让主RAN网元及时了解到终端设备的最新状态通知,可配置一个预设上报周期。辅RAN网元向主RAN网元上报了不活动状态通知后,可以启动定时器,定时时长为预设上报周期,以便辅RAN网元向主RAN网元周期性上报终端设备的状态通知。
可选的,考虑到终端设备可能长时间处于没有数据传输到情况,为了避免辅RAN网元不断的上报终端设备的不活动状态通知造成网络资源的浪费。本申请实施例中还可配置一个不活动状态通知的上报次数的阈值,即辅RAN网元上报不活动状态通知的次数达到该上报次数的阈值,可不用再继续上报不活动状态通知。
可选的,辅RAN网元可主动向主RAN网元上报不活动状态通知。如设置一个不活动状态的时间阈值,当辅RAN网元确定终端设备的不活动时间达到该时间阈值时,则向主RAN网元上报终端设备的不活动状态通知。
203、主RAN网元接收到辅RAN网元发送的终端设备的状态通知,并根据该终端设备的状态通知和自身的数据传输情况确定终端设备在预设时间内是否一直没有数 据传输。
具体的,若主RAN网元接收到辅RAN网元发送的终端设备的活动状态通知,则可直接确定该终端设备在预设时间内有数据传输,确定保持终端设备的连接态。
或者,若主RAN网元接收到辅RAN网元发送的终端设备的不活动状态通知,则需要进一步根据主RAN网元自身的数据传输情况确定。具体的,若主RAN网元在预设时间内传输了终端设备的数据,则确定该终端设备在预设时间内有数据传输,确定保持终端设备的连接态;若主RAN网元在预设时间内一直没有传输终端设备的数据,则确定终端设备在预设时间内一直没有数据传输,确定控制终端设备由连接态进入去激活态。
本申请实施例还提供了一种连接建立的方法,如图5所示,具体包括:
301、主RAN网元向终端设备发送连接挂起指示。
其中,连接挂起指示是用于指示终端设备由连接态进入去激活状态的,例如可以是连接挂起请求消息,连接释放请求,或者连接去激活请求。
可选的,主RAN网元还可为终端设备配置测量控制信息,即测量配置信息,该测量配置信息包括测量对象,可用于终端设备在后续连接恢复过程中,进行小区测量时使用。该测量配置信息也可包括驻留小区的信息,测量对象的信息,以及驻留小区与测量对象的映射关系,可如下表所示。举例说明,若驻留小区为小区1,则驻留小区对应的测量对象为频点F1。若驻留小区为小区5,则驻留小区对应的测量对象为频点F6,或小区1,以此类推。
表一 驻留小区与测量对象的映射关系表
驻留小区 | 测量对象 |
小区1 | 频点F1 |
小区2、3、4 | 频点F2 |
小区5 | 频点F3,小区1 |
小区6 | 无 |
可选的,所述测量配置信息还可包括测量标识,所述测量标识可用于识别后续终端设备上报的,该测量配置信息对应的小区测量的结果。
302、终端设备接收到主RAN网元发送到连接挂起指示后,获取测量配置信息,并根据终端设备当前的驻留小区的信息确定待测量对象。
具体的,若主RAN网元向终端设备发送了测量配置信息,则终端设备根据驻留小区确待测量对象。若测量配置信息中包含测量对象的标识,则可确定该测量对象为待测量对象。若测量信息中包括驻留小区与测量对象的映射关系,则根据终端设备当前的驻留小区确定待测量对象。举例说明,如上表所示,若终端设备当前的驻留小区为小区1,那么可确定频点F1为待测量对象。其中,所述测量对象为配置的载波聚合或者多连接的候选的辅小区,或者候选辅小区所在的频点。
可选的,终端设备也可从当前的驻留小区的系统消息中获取,当前的驻留小区的系统消息包含测量配置信息,而该测量配置信息中包括测量对象,终端设备确定该测量对象为待测量对象。
可选的,测量对象还可包含用于指示终端设备在去激活态时进行测量的指示信息。 303、终端设备启动对待测量对象进行小区测量,并向终端设备当前的驻留小区所对应的RAN网元上报小区测量的结果。
其中,终端设备当前的驻留小区所对应的RAN网与终端设备在连接态时的主RAN网元可以为相同的RAN网元,也可为不同的RAN网元。
可选的,终端设备可在确定待测量对象后,启动对待测量对象的小区测量。可选的,终端设备也可在确定有数据需要传输时,再启动对待测量对象的小区测量。可选的,终端设备也可以在接收到寻呼后,启动对待测量对象的小区测量。可选的,终端设备也可以在确定向驻留小区所对应的RAN网元发送连接恢复请求信息之前,或同时,或之后启动小区测量。本申请实施例并不限定终端设备启动小区测量的具体时间点。
相应的,终端设备可在连接恢复请求信息所在的消息中携带该小区测量结果,也可以单独发送该小区测量结果。本申请实施例对此不做限定。可选的,小区测量的结果在上报时还可携带测量标识,便于RAN网元根据该测量标识确定与测量配置信息相对应的测量结果。
304、终端设备当前的驻留小区所对应的RAN网元根据小区测量的结果确定辅小区的配置信息,并发送给终端设备。
305、终端设备根据接收到的辅小区的配置信息,恢复与辅小区的配置信息指示的RAN网元的连接。
在本申请实施例提供的一种连接建立的方法中,处于去激活态的终端设备可根据当前的驻留小区确定待测量对象,提前对待测量对象进行小区测量,而后当前的驻留小区对应的RAN网元可根据该小区测量的结果为终端设备确定辅小区的配置信息。这样,有利于加快终端设备连接恢复的过程,有利于提高网络的传输效率。
