Description
本申请要求于2014年5月9日提交中国专利局、申请号为PCT/CN2014/077181,发明名称为“一种用户设备及基站、一种接入基站及无线链路监听方法”的国际专利申请的优先权,其全部内容通过引用结合在本申请中。
本发明涉及通信技术领域,尤其涉及一种用户设备及基站、一种接入基站及无线链路监听方法。
随着长期演进(LTE, Long Term Evolution)移动通信系统的发展,为了使演进系统能够提供更高的传输速率、更短的传输时延,演进系统逐渐演变成由两个基站同时为用户设备(UE, User Equipment)提供服务。第一基站(MeNB,Macro eNodeB)可将数据通过第二基站的主小区(PSCell, Primary Secondary Cell)分流给UE,或者,PSCell可直接从核心网获得数据,将数据传给UE。在UE与PSCell通信之前,UE可能需要对PSCell发起随机接入过程(RA,Random Access),当接入到PSCell之后UE才能与PSCell进行通信,若在发起随机接入过程时发生无线链路失败(RLF, Radio Link Failure),UE就会向第一基站上报RLF失败通知。
现有技术中,第一基站在UE发起随机接入过程之前发送RLF失败的条件给UE,其中,RLF失败的条件包括UE在随机接入过程中发送随机接入扰码的预设的最大次数,当UE随机接入扰码的次数大于预设的最大次数时,则向第一基站上报RLF失败。其中,UE发起随机接入过程的分为两类,一类是UE初始请求接入PSCell发起的随机接入过程;另一类则是UE在成功接入PSCell之后,为了其他的如获取上行资源的需要,后续再对PSCell发起随机接入过程。现有技术中针对这两类随机接入过程使用的是同一个最大次数,然而在实际运用中,UE初始发起的随机接入过程的成功率往往比后续发起的随机接入过程的成功率低,因此,若使用的是同一个最大次数,会降低UE初始发起随机接入过程的成功率,最终导致UE对PSCell的随机接入失败,不利于
UE与PSCell的数据传输。
此外,为了保证与PSCell的无线链路质量满足数据传输的需求,UE需要对PSCell的无线链路执行无线链路监听,然而现有技术中还未对无线链路监听的触发条件进行规定,导致UE对启动无线链路监听的时间无法把握,不能体现无线链路监听的实质功能。

为了更清楚地说明本发明实施例或现有技术中的技术方案,下面将对实施例中所需要使用的附图作简单地介绍,显而易见地,下面描述中的附图仅仅是本发明的一些实施例,对于本领域普通技术人员来讲,在不付出创造性劳动的前提下,还可以根据这些附图获得其他的附图。

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作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。
采用本发明实施例,通过限定用户设备请求接入的时间或者初始及后续接入的发送随机接入扰码的次数提高用户设备接入第二基站的效率。
请参阅图1,如图1所示为本发明实施例的一种用户设备的一实施例的结构示意图。本发明实施例针对的第二基站可为第二基站的主小区PSCell。涉及的请求接入过程可为随机接入过程。UE从第一基站获得的参数以及指示信息等信息均由第二基站设置,通过第二基站的X2接口传送至第一基站,再由第一基站发送给UE。
本发明实施例所涉及的用户设备包括第一接收模块100、第一发送模块110以及第一通知模块120。
第一接收模块100,用于接收第一基站发送的第一指示信息,第一指示信息包括用户设备初始请求接入第二基站所需的时间段,或者,包括用户设备在初始请求接入第二基站时向第二基站发送随机接入扰码的预设的第一最大次数。
结合图11,具体实现中,为了提高UE随机接入的成功率,在UE发起随机接入过程前,第一基站发送第一指示信息给UE。其中,第一指示信息包括UE初始请求接入PSCell所需的时间段,或者,包括UE在初始请求接入PSCell时向PSCell发送随机接入扰码的预设的第一最大次数。其中,设置初始随机接入过程的时间段能够放松接入PSCell的时长,增加成功接入PSCell的机会。相比限定UE发送随机接入扰码的次数而言,限定随机接入过程的时间段更弹性化,UE可在该时间段内无数次发送扰码,使随机接入过程的效率更高。此
外,若第一基站发送的第一指示信息中包含的是UE在初始请求接入PSCell时向PSCell发送随机接入扰码的预设的第一最大次数,则相对后续限定发送随机接入扰码的次数而言可适当增加初始发送的次数,也可以提高随机接入的效率。
作为一种可实施的方式,在第一基站发送第一指示信息之前,第一指示信息由第二基站设置,通过第一基站的无线资源控制RRC(Radio Resource Control)重配置消息下的非移动性信息发送给第一接收模块100。
作为一种可实施的方式,第一指示信息由第二基站设置,通过第一基站的无线资源控制重配置消息下的第二小区组相关的配置信息发送给第一接收模块100。第一基站可将第一指示信息通过RRC重配置消息下的不同信息发送给UE,确保UE能够接收到第一指示信息。
作为一种可实施的方式,第一接收模块100通过第一基站发送的第二基站添加信息或者双连接建立信息获得第一指示信息。第一基站可将第一指示信息由第二基站添加信息或者双连接建立信息进行携带,再通过RRC重配置消息下的不同信息发送给UE。
作为一种可实施的方式,第一指示信息还包括用户设备在接入第二基站之后,第一发送模块110向第二基站发送随机接入扰码的预设的第二最大次数,第二最大次数用于当用户设备在请求接入过程中第一发送模块110发送随机接入扰码的次数大于第二最大次数时,第一通知模块120通过用户设备高层通知第一基站用户设备请求接入失败。
具体实现中,当后续发生随机接入失败时,UE通知UE高层第二基站随机接入出现问题,由UE高层向第一基站发送第二基站小区组失败的通知。
作为一种可实施的方式,第一接收模块100,还用于若用户设备接入到第二基站,则接收第一基站发送的第二指示信息,第二指示信息包括第一发送模块110向第二基站发送随机接入扰码的第二最大次数。
可选的,在UE接入到PSCell之后,后续发起的随机接入过程可限定向PSCell发送随机接入扰码的次数。UE为获取上行资源继续向PSCell继续发起随机接入过程,在发起随机接入过程之前,UE依旧会收到第一基站发送的第二指示信息,此时第二指示信息中可包括第二最大次数。因此在初始随机接入过程前接收的第一指示信息不再需要包含第二最大次数。
第一发送模块110,用于向第二基站发送随机接入扰码。
具体实现中,在UE接收到第一基站发送的第一指示信息之后,根据第一指示信息向PSCell发起随机接入过程,即向PSCell发送随机接入扰码,以等待PSCell的反馈。
作为一种可实施的方式,若第一指示信息包括用户设备初始请求接入第二基站所需的时间段,则当第一发送模块110初始向第二基站发送随机接入扰码时,或者第一发送模块110初始决定向第二基站发送随机接入扰码时,开启定时器,定时器的定时时间为第一指示信息中的时间段。
作为一种可实施的方式,第一发送模块110在定时时间内持续向第二基站发送随机接入扰码。
需要注意的是,UE向PSCell持续发送随机接入扰码是指,当前一次发送随机接入扰码给PSCell时接入失败之后,UE重传随机接入扰码给PSCell。
作为一种可实施的方式,当第一接收模块100接收第一基站发送的第一指示信息时,开启定时器。
可选的,当第一指示信息中包括UE初始请求接入PSCell所需的时间段时,需要定时器进行计时,定时器的定时时间即为UE初始请求接入PSCell所需的时间段。本发明实施例对定时器开启的时间进行限定,对于开启定时器的时间也可由第二基站进行设置,则第一指示信息还包括定时器的开启时间,通过第一基站发送给UE。开启定时器的时间也可由UE本地存储或者内部实现。定时器既可以在UE初始向PSCell发送随机接入扰码的时刻开启,也可在UE高层初始决定向PSCell发送随机接入扰码的时刻开启,还可在UE获取第一指示信息的时刻开启。
可选的,当UE开启定时器之后,在定时器的定时时间内向PSCell发送随机接入扰码,若接收到PSCell反馈的随机接入响应消息(RAR,Random Access Respond)中没有UE自身的识别码,则认为此次随机接入响应失败,并继续向PSCell重传随机接入扰码。或者在UE发送针对随机接入响应消息的消息后,发生竞争接入失败,并继续向PSCell重传随机接入扰码,当UE开启定时器之后,在定时器的定时时间内没有接入PSCell,则认为此次随机接入失败。
可选的,若第一基站发送的第一指示信息中包含的是UE在初始请求接入PSCell时向PSCell发送随机接入扰码的预设的第一最大次数,则在UE初始
发送随机接入扰码时开始计数。若接收到PSCell反馈的RAR消息中没有UE自身的识别码,则认为此次随机接入响应失败,并继续向PSCell重传随机接入扰码,每发送一次随机接入扰码计数器即加1。举例说明,PSCell可设置第一最大次数为8,并通过第一指示信息发送给UE,UE初始发送随机接入扰码时计数器为1,第二次发送随机接入扰码时计数器为2,当计数器最后累计的数值为9时,由于9大于8,则认为随机接入失败。当UE在计数器的数值小于或者等于8的时候成功接入PSCell,计数器则停止计数,等待下一次UE在接入PSCell再次发起时根据第二最大次数开始计数。其中,第二最大次数既可以在初始UE接收的第一指示信息中,也可以在UE接入PSCell之后,从第一基站接收的第二指示信息中。
第一通知模块120,用于根据第一指示信息,若用户设备在时间段内接入第二基站失败,或者,若用户设备在初始请求接入第二基站时向第二基站发送随机接入扰码的次数大于第一最大次数,则通知第一基站用户设备发生第二基站小区组失败。
具体实现中,若第一指示信息包括的是UE初始请求接入PSCell所需的时间段,则在随机接入过程中,若UE在该时间段结束时依然没有接入PSCell,UE则向第一基站上报第二基站小区组失败。
可选的,若第一指示信息包括的是UE在初始请求接入PSCell时向PSCell发送随机接入扰码的预设的第一最大次数,则当UE发送随机接入扰码的次数大于第一最大次数时,UE向第一基站上报第二基站小区组失败。
作为一种可实施的方式,第一通知模块120通知的第二基站小区组失败为初始请求接入第二基站失败,或者请求接入第二基站失败。
具体实现中,UE通知的第二基站小区组失败既可仅仅为初始随机接入过程失败,也可不区分随机接入过程是何时发生失败,直接向第一基站上报发生失败。
作为一种可实施的方式,第二基站小区组失败包括定时器到期的信息。
可选的,第二基站小区组失败还可包括UE发送随机接入扰码的次数大于第一最大次数的信息。
可选的,若UE在获得PSCell反馈的RAR消息中找到UE的识别码,此时则认为UE成功接入到PSCell。此外,RAR消息中还包括UE后续使用的上
行资源,UE便利用上行资源与PSCell进行数据传输。
作为一种可实施的方式,用户设备还包括第一传输模块130。
第一传输模块130,用于若用户设备接入到第二基站,则与第一基站和第二基站通过双连接的方式进行数据传输。
具体实现中,当UE成功接入到PSCell之后,PSCell既可以从第一基站分流部分数据并将数据传输给UE,PSCell也可直接从核心网将数据传输给UE,实现双连接的数据传输,提高传输速率,减少传输时延。
作为一种可实施的方式,用户设备还包括关闭模块140。
关闭模块140,用于若用户设备在定时器的定时时间内接入到第二基站,则关闭定时器。
作为一种可实施的方式,用户设备向第二基站的小区或者第二基站的主第二小区请求接入。
采用本发明实施例图1,提供一种用户设备,能够通过第二基站的主小区限定用户设备发起的随机接入过程的时间或者发送随机接入扰码的次数,提高用户设备接入第二基站的主小区的成功率,让用户设备能更快接入第二基站的主小区。此外,对用户设备初次发起随机接入过程以及接入第二基站的主小区后继续发起的随机接入过程各自的最大次数进行区分,能加快用户设备接入第二基站的主小区的效率。
请参阅图2,图2是本发明实施例的一种用户设备的第一发送模块的结构示意图。如图2所示的第一发送模块110包括:第一开启单元200以及发送单元210。
第一开启单元200,用于当第一发送模块110初始向第二基站发送随机接入扰码时,或者第一发送模块110初始决定向第二基站发送随机接入扰码时,开启定时器,定时器的定时时间为第一指示信息中的时间段。
发送单元210,用于在定时时间内持续向第二基站发送随机接入扰码。
作为一种可实施的方式,第一开启单元200,还用于当第一接收模块100接收第一基站发送的第一指示信息时,开启定时器。
具体实现中,第一开启单元200具体用于当用户设备在第二基站的主小区限定发起随机接入过程的时间时,对定时器的开启时间进行控制。

请参阅图4,图4是本发明实施例的一种基站的一实施例的结构示意图。本发明实施例所涉及的一种基站为第一基站,用于控制用户设备与第二基站之间的通信。本发明实施例针对的第二基站可为第二基站的主小区PSCell。涉及的请求接入过程可为随机接入过程。UE从第一基站获得的参数以及指示信息等信息均由第二基站设置,通过第二基站的X2接口传送至第一基站,再由第一基站发送给UE。
本发明实施例所涉及的基站包括发送模块400以及接收模块410。
发送模块400,用于向用户设备发送第一指示信息,第一指示信息包括用户设备初始请求接入第二基站所需的时间段,或者,包括用户设备在初始请求接入第二基站时向第二基站发送随机接入扰码的预设的第一最大次数。
具体实现中,当UE需要和PSCell进行数据传输时,PSCell将相应参数进行设置生成第一指示信息,并将第一指示信息发送给第一基站,由第一基站发送给UE。其中,第一指示信息包括用户设备初始请求接入第二基站所需的时间段,或者,包括用户设备在初始请求接入第二基站时向第二基站发送随机接入扰码的预设的第一最大次数。
其中,第一指示信息包括UE初始请求接入PSCell所需的时间段,或者,包括UE在初始请求接入PSCell时向PSCell发送随机接入扰码的预设的第一最大次数。其中,设置初始随机接入过程的时间段能够放松接入PSCell的时长,增加成功接入PSCell的机会。相比限定UE发送随机接入扰码的次数而言,限定随机接入过程的时间段更弹性化,UE可在该时间段内无数次发送扰码,使随机接入过程的效率更高。此外,若第一基站发送的第一指示信息中包含的是UE在初始请求接入PSCell时向PSCell发送随机接入扰码的预设的第一最大次数,则相对后续限定发送随机接入扰码的次数而言可适当增加初始发送的次数,也可以提高随机接入的效率。若限定UE初始请求接入PSCell所需的时
间段则采用定时器进行计时,控制定时器开启的时间详见实施例图1,本实施例则不再赘述。若限定UE在初始请求接入PSCell时向PSCell发送随机接入扰码的最大次数,则可采用计数器进行计数,同样计数器具体对发送随机接入扰码的技术方式详见实施例图1,本实施例则不再赘述。

第二基站的主小区的效率。
请参阅图6,图6是本发明实施例的一种用户设备的第三实施例的结构示意图。本发明实施例针对的第二基站可为第二基站的主小区PSCell。在UE接入PSCell之后,在后续与PSCell的数据传输中,UE对PSCell的无线链路执行无线链路监听。本发明实施例针对触发UE无线链路监听的条件进行举例说明。
本发明实施例所涉及的用户设备包括第二接收模块600以及开启模块610。
第二接收模块600,用于接收第一基站发送的第二指示信息,第二指示信息包括针对第二基站主小区的无线链路执行的无线链路监听的参数。
具体实现中,无线链路监听的参数可为同步计数器、失步计数器以及失步定时器的定时时间等参数。还可以进一步包括同步门限值,失步门限值。所述同步门限值,失步门限值还可以为UE内部实现获取。
可选的,当第二接收模块600接收到第一基站发送的参数时,第二基站主小区为已经给UE提供服务的第二基站的服务小区。
具体实现中,UE接收的参数为正与UE进行数据传输的当前的PSCell。
作为一种可实施的方式,由于第二基站有若干个主小区,当UE在移动过程中时,与原先接入的主小区之间的信号会减弱,此时第二基站可将当前PSCell替换为其他主小区,UE进而与其他主小区继续进行数据传输,此时UE接收到的参数则为针对其他主小区的执行的无线链路监听的参数。
可选的,第二指示信息由第二基站设置,通过第一基站的无线资源控制重配置消息下的非移动性信息发送给第二接收模块600。
可选的,第二指示信息由第二基站设置,通过第一基站的无线资源控制重配置消息下的第二小区组相关的配置信息发送给第二接收模块600。
可选的,第二接收模块600通过第一基站发送的第二基站主小区添加信息或者双连接建立信息获得第二指示信息。
具体实现中,下面对UE发起的无线链路监听过程进行简单说明。在无线链路监听中UE每隔一定的周期评估上一周期的无线链路的信号质量,将信号质量与同步门限值和失步门限值进行比较。当信号质量低于失步门限值时,对
应的失步计数器则加1,同时同步计数器清零;当信号质量高于同步门限值时,对应的同步计数器加1,同时失步计数器清零。因此,同步计数器和失步计数器中,只要任意一方开始计数,另一方则及时清零,直到另一方开始计数为止。在当失步计数器连续累积了预定数量时,则启动失步定时器(注意,失步定时器与实施例图1至图5所提及的定时器不同),在失步定时器预定的时间内,如果同步计数器没有连续累积预定的数量,则表明无线链路失败,UE则向第一基站上报发生第二基站小区组失败。其中无线链路监听过程中所需要的参数都可由第二基站设置,再由第一基站转发给用户设备。
开启模块610,用于根据触发条件开启无线链路监听,其中触发无线链路监听的条件为包括以下至少一种:当第二接收模块600接收到第一基站发送的针对第二基站主小区的无线链路执行的无线链路监听的参数时,或者,当用户设备接入到第二基站主小区时,或者,当用户设备的第二发送模块640向第二基站主小区发送随机接入扰码时。
具体实现中,对于条件一,当UE接收到第一基站发送的无线链路监听的参数的时刻即开启无线链路监听;对于条件二,当UE成功接入到PSCell时即开启无线链路监听,UE利用之前接收到第一基站发送的针对PSCell的无线链路执行的无线链路监听的参数执行无线链路监听;对于条件三,在UE决定利用随机接入过程接入PSCell时,即开启无线链路监听。对于开启无线链路监听的触发条件进行明确地限定,有利于UE无线链路监听的实施,提高无线链路监听的效率。
作为一种可实施的方式,开启模块包括计数单元(未图示)以及开启定时器单元(未图示)。
计数单元(未图示),用于根据触发条件进行同步计数和/或失步计数。
具体实现中,计数单元(未图示)包括上述同步计数器和失步计数器。本发明实施例可以在满足至少一种触发条件时启动同步计数器和/或失步计数器,即既可以在用户设备接入第二基站主小区之前开启,也可以在用户设备接入到第二基站主小区之后开启,还可以在任意时刻开启。
开启定时器单元(未图示),用于开启失步定时器。
可选的,开启定时器单元(未图示)开启失步定时器的条件为包括满足触发条件,以及,计数单元根据失步计数累积的数值大于或等于第一预设值。
具体实现中,开启定时器单元(未图示)在满足触发条件下,在计数单元(未图示)进行同步计数和/或失步计数,并满足失步计数器连续累积了预定数量之后开启。
作为一种可实施的方式,失步定时器在失步计数器连续累积了预定数量时,以及用户设备接入到第二基站主小区时开启。其中,对失步计数器连续累积了预定数量与用户设备接入到第二基站主小区的时间顺序不作限定,只要满足上述两个条件,即可开启失步定时器。因此,即使用户设备在任意时刻开启了同步计数器和/或失步计数器分别进行同步计数和/或失步计数,若用户设备仍未接入到第二基站主小区,失步定时器仍然不会因为失步计数累积的数值大于或等于第一预设值而启动,从而保证了失步定时器启动的时机。
可选的,用户设备接入到第二基站主小区的方式为以下至少一种:用户设备针对第二基站主小区发起的随机接入过程成功完成,或者,第二发送模块640在发送随机接入扰码的最大次数之内用户设备接入到第二基站主小区,或者,用户设备在初始请求接入第二基站主小区所需的时间段内接入到第二基站主小区,或者,用户设备的第二传输模块630与第二基站主小区开始数据传输时。其中,UE接入PSCell的方式包括实施例图1至图5的接入方式,具体实施过程详见实施例图1至图5,本实施例则不再赘述。
作为一种可实施的方式,用户设备还包括第二通知模块620。
第二通知模块620,用于若用户设备在无线链路监听时发生无线链路失败,则通知第一基站用户设备发生第二基站小区组失败。
具体实现中,若UE发生无线链路失败,则UE向UE高层上报发生随机接入问题,由UE高层通知第一基站无线链路失败。
作为一种可实施的方式,用户设备在无线链路监听时发生无线链路失败的条件为失步定时器到期。
具体的,用户设备在无线链路监听时发生无线链路失败的条件为计数单元(未图示)在失步定时器预定的时间内,根据同步计数累积的数值小于第二预设值。在失步定时器预定的时间内,如果同步计数器连续累积的数值没有达到预定的数量,则表明无线链路失败,用户设备则向第一基站上报发生第二基站小区组失败。
采用本发明实施例图6,能够在用户设备接入第二基站的主小区之后,对
无线链路监听的触发条件进行规定,使UE能对启动无线链路监听的时间充分把握,从而突显用户设备无线链路监听的实质功能。
请参阅图7,图7是本发明实施例的一种用户设备的第四实施例的结构示意图。
如图7所示的用户设备包括第二输入装置700、第二输出装置710、第二存储器720和第二处理器730(用户设备中的第二处理器730的数量可以为一个或多个,图7中以一个处理器为例)。在本发明实施例中,第二输入装置700、第二输出装置710、第二存储器720和第二处理器730可通过总线或其他方式连接,其中,图7中以通过总线连接为例。
在本实施例中,第二处理器730可以通过第二输入装置700接收基站或其他设备发送的指示或信令。同样第二处理器730也可以通过第二输出装置710向基站或其他设备发送指示或信令。
其中,第二存储器720用于存储程序,第二处理器730用于调用程序执行以下步骤:

作为一种可实施的方式,第二处理器730开启失步定时器的条件为包括:满足触发条件,以及,根据失步计数累积的数值大于或等于第一预设值。
作为一种可实施的方式,当通过第二输入装置700接收到第一基站发送的参数时,第二基站主小区为已经给UE提供服务的第二基站的服务小区。
作为一种可实施的方式,第二处理器730还执行如下步骤:若在无线链路监听时发生无线链路失败,则通过第二输出装置710通知第一基站用户设备发生第二基站小区组失败。
作为一种可实施的方式,第二指示信息由第二基站设置,通过第一基站的无线资源控制重配置消息下的非移动性信息发送给第二输入装置700。
作为一种可实施的方式,第二指示信息由第二基站设置,通过第一基站的无线资源控制重配置消息下的第二小区组相关的配置信息发送给第二输入装置700。

采用本发明实施例图7,能够在用户设备接入第二基站的主小区之后,对无线链路监听的触发条件进行规定,使UE能对启动无线链路监听的时间充分把握,从而突显用户设备无线链路监听的实质功能。
请参阅图8,图8是本发明实施例的一种接入基站方法的一实施例的流程示意图。本发明实施例所涉及的一种基站为第一基站,用于控制用户设备与第二基站之间的通信。本发明实施例针对的第二基站可为第二基站的主小区PSCell。涉及的请求接入过程可为随机接入过程。UE从第一基站获得的参数以及指示信息等信息均由第二基站设置,通过第二基站的X2接口传送至第一基站,再由第一基站发送给UE。
如图8所示,本发明实施例的一种接入基站方法包括可以如下步骤:
步骤800,用户设备接收第一基站发送的第一指示信息,第一指示信息包括用户设备初始请求接入第二基站所需的时间段,或者,包括用户设备在初始请求接入第二基站时向第二基站发送随机接入扰码的预设的第一最大次数。
步骤810,用户设备向第二基站发送随机接入扰码。
步骤820,根据第一指示信息,若用户设备在时间段内接入第二基站失败,或者,若用户设备在初始请求接入第二基站时向第二基站发送随机接入扰码的次数大于第一最大次数,则用户设备通知第一基站用户设备发生第二基站小区组失败。
具体实现中,为了提高UE随机接入的成功率,在UE发起随机接入过程前,第一基站发送第一指示信息给UE。其中,第一指示信息包括UE初始请求接入PSCell所需的时间段,或者,包括UE在初始请求接入PSCell时向PSCell发送随机接入扰码的预设的第一最大次数。其中,设置初始随机接入过程的时间段能够放松接入PSCell的时长,增加成功接入PSCell的机会。相比限定UE发送随机接入扰码的次数而言,限定随机接入过程的时间段更弹性化,UE可在该时间段内无数次发送扰码,使随机接入过程的效率更高。此外,若第一基站发送的第一指示信息中包含的是UE在初始请求接入PSCell时向PSCell发送随机接入扰码的预设的第一最大次数,则相对后续限定发送随机接入扰码的次数而言可适当增加初始发送的次数,也可以提高随机接入的效率。
具体实现中,在UE接收到第一基站发送的第一指示信息之后,根据第一指示信息向PSCell发起随机接入过程,即向PSCell发送随机接入扰码,以等待PSCell的反馈。
可选的,UE在该时间段内向PSCell发送随机接入扰码,若接收到PSCell反馈的RAR消息中没有UE自身的识别码,则认为此次随机接入响应失败,并继续向PSCell重传随机接入扰码。或者在UE发送针对随机接入响应消息的消息后,发生竞争接入失败,并继续向PSCell重传随机接入扰码,当UE开启定时器之后,在定时器的定时时间内没有接入PSCell,则认为此次随机接入失败。
具体实现中,若第一指示信息包括的是UE初始请求接入PSCell所需的时间段,则在随机接入过程中,若UE在该时间段结束时依然没有接入PSCell,UE则向第一基站上报第二基站小区组失败。
作为一种可实施的方式,若用户设备接入到第二基站,则用户设备与第一基站和第二基站通过双连接的方式进行数据传输。
作为一种可实施的方式,第一指示信息由第二基站设置,通过第一基站的无线资源控制重配置消息下的非移动性信息发送给用户设备。
作为一种可实施的方式,第一指示信息由第二基站设置,通过第一基站的无线资源控制重配置消息下的第二小区组相关的配置信息发送给用户设备。
作为一种可实施的方式,用户设备通过第一基站发送的第二基站添加信息或者双连接建立信息获得第一指示信息。
作为一种可实施的方式,若第一指示信息包括用户设备初始请求接入第二基站所需的时间段,则当用户设备初始向第二基站发送随机接入扰码时,或者用户设备初始决定向第二基站发送随机接入扰码时,用户设备开启定时器,定时器的定时时间为第一指示信息中的时间段;用户设备在定时时间内持续向第二基站发送随机接入扰码。其中,针对以上两种限定条件在实施例图1已有详尽的描述,本实施例则不再赘述。
作为一种可实施的方式,若第一指示信息包括用户设备初始请求接入第二基站所需的时间段,则当用户设备接收第一基站发送的第一指示信息时,用户设备开启定时器。具体实现中,规定了定时器开启的时间,定时器既可以在UE初始向PSCell发送随机接入扰码时开启,也可以在UE初始决定向PSCell发送随机接入扰码时开启,还可以在UE接收第一基站发送的第一指示信息时开启。其中,开启定时器的具体实施步骤详见实施例图1,本实施例则不再赘述。
作为一种可实施的方式,用户设备通知的第二基站小区组失败为初始请求接入第二基站失败,或者请求接入第二基站失败。
作为一种可实施的方式,第二基站小区组失败包括定时器到期的信息。
作为一种可实施的方式,若用户设备在定时器的定时时间内接入到第二基站,则用户设备关闭定时器。
作为一种可实施的方式,第一指示信息还包括用户设备在接入第二基站之后,用户设备向第二基站发送随机接入扰码的预设的第二最大次数,第二最大次数用于当用户设备在请求接入过程中发送随机接入扰码的次数大于第二最大次数时,用户设备通过用户设备高层通知第一基站用户设备请求接入失败。
作为一种可实施的方式,若用户设备接入到第二基站,则用户设备接收第一基站发送的第二指示信息,第二指示信息包括用户设备向第二基站发送随机接入扰码的第二最大次数。其中,初始随机接入过程可利用限定初始随机接入的时间段以及发送随机接入扰码的次数来请求接入
作为一种可实施的方式,用户设备向第二基站的小区或者第二基站的主第二小区请求接入PSCell,而在UE接入PSCell之后,后续的随机接入过程可通过限定UE发送随机接入扰码的第二最大次数请求接入PSCell。
采用本发明实施例图8,能够通过第二基站的主小区限定用户设备发起的随机接入过程的时间或者发送随机接入扰码的次数,提高用户设备接入第二基站的主小区的成功率,让用户设备能更快接入第二基站的主小区。此外,对用户设备初次发起随机接入过程以及接入第二基站的主小区后继续发起的随机接入过程各自的最大次数进行区分,能加快用户设备接入第二基站的主小区的效率。
请参阅图9,图9是本发明实施例的一种接入基站方法的另一实施例的流程示意图。
如图9所示的一种接入基站方法的另一实施例可以包括如下步骤:
步骤900,第一基站向用户设备发送第一指示信息,第一指示信息包括用户设备初始请求接入第二基站所需的时间段,或者,包括用户设备在初始请求接入第二基站时向第二基站发送随机接入扰码的预设的第一最大次数。
步骤910,根据第一指示信息,若用户设备在时间段内请求接入第二基站失败,或者,若用户设备在初始请求接入第二基站时向第二基站发送随机接入扰码的次数大于第一最大次数,则第一基站接收用户设备发送第二基站小区组失败的通知。
具体实现中,当UE需要和PSCell进行数据传输时,PSCell将相应参数进行设置生成第一指示信息,并将第一指示信息发送给第一基站,由第一基站发送给UE。其中,第一指示信息包括用户设备初始请求接入第二基站所需的时间段,或者,包括用户设备在初始请求接入第二基站时向第二基站发送随机接入扰码的预设的第一最大次数。
其中,第一指示信息包括UE初始请求接入PSCell所需的时间段,或者,包括UE在初始请求接入PSCell时向PSCell发送随机接入扰码的预设的第一最大次数。若限定UE初始请求接入PSCell所需的时间段则采用定时器进行计时,控制定时器开启的时间详见实施例图1,本实施例则不再赘述。若限定UE在初始请求接入PSCell时向PSCell发送随机接入扰码的最大次数,则可
采用计数器进行计数,同样计数器具体对发送随机接入扰码的技术方式详见实施例图1,本实施例则不再赘述。
具体实现中,当UE在图1实施例中的定时器的定时时间结束后随机接入过程仍然失败,或者,UE在初始请求接入PSCell时向PSCell发送随机接入扰码的次数大于第一最大次数,则发送第二基站小区组失败的通知给第一基站。UE在接入PSCell后,后续发起的随机接入过程可限定向PSCell发送随机接入扰码的次数,即第二最大次数。若UE在后续接入PSCell时向PSCell发送随机接入扰码的次数大于第二最大次数,则UE通知UE第二基站随机接入出现问题,由UE高层向第一基站发送第二基站小区组失败的通知。
作为一种可实施的方式,第一指示信息由第二基站设置,通过第一基站的无线资源控制重配置消息下的非移动性信息发送给用户设备。
作为一种可实施的方式,第一指示信息由第二基站设置,通过第一基站的无线资源控制重配置消息下的第二小区组相关的配置信息发送给用户设备。
作为一种可实施的方式,用户设备通知的第二基站小区组失败为初始请求接入第二基站失败,或者请求接入第二基站失败。
作为一种可实施的方式,第二基站小区组失败包括定时器到期的信息。
作为一种可实施的方式,第一指示信息还包括用户设备在接入第二基站之后,用户设备向第二基站发送随机接入扰码的预设的第二最大次数,第二最大次数用于当用户设备在请求接入过程中发送随机接入扰码的次数大于第二最大次数时,第一基站接收用户设备通过用户设备高层通知第二基站小区组失败。
具体实现中,当后续发生随机接入失败时,UE通知UE高层第二基站随机接入出现问题,由UE高层向第一基站发送第二基站小区组失败的通知。
作为一种可实施的方式,若用户设备接入到第二基站,则第一基站向用户设备发送第二指示信息,第二指示信息包括用户设备向第二基站发送随机接入扰码的第二最大次数。
采用本发明实施例图9,能够通过第二基站的主小区限定用户设备发起的随机接入过程的时间或者发送随机接入扰码的次数,将限定的内容发送给用户设备,提高用户设备接入第二基站的主小区的成功率,让用户设备能更快接入第二基站的主小区。此外,对用户设备初次发起随机接入过程以及接入第二基
站的主小区后继续发起的随机接入过程各自的最大次数进行区分,能加快用户设备接入第二基站的主小区的效率。
请参阅图10,图10是本发明实施例的一种无线链路监听方法的一实施例的流程示意图。本发明实施例针对的第二基站可为第二基站的主小区PSCell,在UE接入PSCell之后,在后续与PSCell的数据传输中,UE对PSCell的无线链路执行无线链路监听。本发明实施例针对触发UE无线链路监听的条件进行举例说明。
如图10所示的一种无线链路监听方法的一实施例可以包括以下步骤:
步骤1000,用户设备接收第一基站发送的第二指示信息,第二指示信息包括针对第二基站主小区的无线链路执行的无线链路监听的参数。
步骤1010,用户设备根据触发条件开启无线链路监听,其中触发无线链路监听的条件为包括以下至少一种:当用户设备接收到第一基站发送的针对第二基站主小区的无线链路执行的无线链路监听的参数时,或者,当用户设备接入到第二基站主小区时,或者,当用户设备向第二基站主小区发送随机接入扰码时。
作为一种可实施的方式,上述步骤1010可以包括:根据触发条件进行同步计数和/或失步计数;开启失步定时器。
作为一种可实施的方式,开启失步定时器的条件为包括:满足触发条件,以及,根据失步计数累积的数值大于或等于第一预设值。
具体实现中,无线链路监听的参数可为同步计数器、失步计数器以及定时时间等参数。还可以进一步包括同步门限值,失步门限值。所述同步门限值,失步门限值还可以为UE内部实现获取。
具体实现中,对于条件一,当UE接收到第一基站发送的无线链路监听的参数的时刻即开启无线链路监听;对于条件二,当UE成功接入到PSCell时即开启无线链路监听,UE利用之前接收到第一基站发送的针对PSCell的无线链路执行的无线链路监听的参数执行无线链路监听;对于条件三,在UE决定利用随机接入过程接入PSCell时,即开启无线链路监听。对于开启无线链路监听的触发条件进行明确地限定,有利于UE无线链路监听的实施,提高无线链路监听的效率。
作为一种可实施的方式,当用户设备接收到第一基站发送的参数时,第二基站主小区为已经给UE提供服务的第二基站的服务小区。
可选的,由于第二基站有若干个主小区,当UE在移动过程中时,与原先接入的主小区之间的信号会减弱,此时第二基站可将当前PSCell替换为其他主小区,UE进而与其他主小区继续进行数据传输,此时UE接收到的参数则为针对其他主小区的执行的无线链路监听的参数。
作为一种可实施的方式,若用户设备在无线链路监听时发生无线链路失败,则用户设备通知第一基站用户设备发生第二基站小区组失败。
作为一种可实施的方式,第二指示信息由第二基站设置,通过第一基站的无线资源控制重配置消息下的非移动性信息发送给用户设备。
作为一种可实施的方式,第二指示信息由第二基站设置,通过第一基站的无线资源控制重配置消息下的第二小区组相关的配置信息发送给用户设备。
作为一种可实施的方式,用户设备通过第一基站发送的第二基站主小区添加信息或者双连接建立信息获得第二指示信息。
具体实现中,UE发起的无线链路监听过程详见实施例图6,本实施例则不再赘述。
作为一种可实施的方式,用户设备在无线链路监听时发生无线链路失败的条件为失步定时器到期。
作为一种可实施的方式,用户设备接入到第二基站主小区的方式为以下任意一种:用户设备针对第二基站主小区发起的随机接入过程成功完成,或者,用户设备在发送随机接入扰码的预设的最大次数之内接入到第二基站主小区,或者,用户设备在初始请求接入第二基站主小区所需的时间段内接入到第二基站主小区,或者,用户设备与第二基站主小区开始数据传输时。
采用本发明实施例图10,能够在用户设备接入第二基站的主小区之后,对无线链路监听的触发条件进行规定,使UE能对启动无线链路监听的时间充分把握,从而突显用户设备无线链路监听的实质功能。
