Description

组通信方法和装置 技术领域
本发明实施例涉及无线通信技术领域,尤其涉及一种组通信方法和装置。
背景技术
组通信是指将多个用户设备(User Equipment,UE)作为一组进行通信的机制。组通信的特点是一组内的多个UE可能同时接收到相同的数据。
在目前的语音通信中,组通信一般是通过组通信服务器来完成,组内的每个UE和组通信服务器建立信令连接和语音连接。组通信服务器通过与UE之间的信令连接控制可以发送上行语音的UE,并将收到的上行语音送达组内的其他UE。但在语音通信的组通信中,每个UE在接入网侧都需要单独的下行语音通道,虽然组内的多个UE接收到的下行语音是相同的,但让然需要向每个UE单独发送一份下行语音数据,浪费了接入网侧的无线资源。
另一方面,在无线通信中还有一种点到多点(Point to Multipoint,PTM)技术,PTM一般通过多媒体广播组播业务(Multimedia Broadcast Multicast Service,MBMS)技术实现。增强的多媒体广播组播业务(enhance Multimedia Broadcast Multicast Service,eMBMS)技术是一种利用广播信道向多个UE传达相同业务的技术,接收同一业务的一组UE使用相同的下行配置来进行业务接收,而不必为每个UE建立独立的链路。
但目前的eMBMS采用组播广播单频网络(Multicast Broadcast Single Frequency Network,MBSFN)技术,一个区域中的所有小区均采用相同的资源发送业务。若在应用eMBMS进行组通信的区域内,组内的UE分布不均匀,某些小区内的用户数量可能很少或没有用户,则在用户数量很少或没有用户的小区中,无线资源的使用效率较低。

具体实施方式
为使本发明实施例的目的、技术方案和优点更加清楚,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。
图1为语音通信中组通信的系统架构示意图,如图1所示,在网络中设置有组通信服务器11;若干个基站,图1中以基站12和基站13两个基站为例进行示意;若干个UE,图1中以UE14至UE18五个UE为例进行示意。其中UE14、UE15和UE16接入基站12,UE17和UE18接入基站13。
在图1所示的系统中,UE14至UE18作为一组UE,可以互相进行组通 信。但在图1所示系统中,同一时间内一组UE中只有一个UE能够发送语音数据,其他UE接收该UE的语音数据。例如,UE14向基站12发送语音数据,然后基站12向组通信服务器11发送该语音数据。组通信服务器11将该语音数据再发送给基站12和基站13,基站12和基站13再分别将该语音数据发送给UE15、UE16、UE17和UE18。在图1所示系统中,每个UE在接入网侧都需要单独的下行语音通道,因此浪费了接入网侧的资源。
图2为MBMS的系统架构示意图,如图2所示,在网络中设置有广播组播业务中心(Broadcast Multicast Service Center,BMSC)21,多小区/组播协调实体(Multi-cell/multicast Coordination Entity,MCE)22,若干个基站,图2中以基站23和基站24两个基站为例进行示意;若干个UE,图2中以UE25至UE29五个UE为例进行示意。其中UE25、UE26和UE27接入基站23,UE28和UE29接入基站24。
在图2所示的系统中,UE25至UE29作为一组UE,可以接收相同的广播组播数据。BMSC21向基站23和基站24发送广播组播数据,MCE22用于协调各基站的广播组播数据。各基站通过物理组播信道(Physical Multicast Channel,PMCH)向接入的UE发送广播组播数据。但在图2所示的系统中,各基站发送给UE的广播组播数据都是相同的,若存在网络中还存在一个没有UE接入的基站,或者某一基站的某小区没有UE接入,则该基站仍然需要接收BMSC发送的广播组播数据,并仍然需要在PMCH发送该广播组播数据。这样会导致无线资源的效率较低。
综上所述,目前的组通信方法都存在一定的问题,从而导致无线资源的浪费或使用效率较低。
图3为本发明实施例提供的基站实施例一的结构示意图,如图3所示,本实施例的基站包括:
处理模块31,用于确定在第一小区启动调度PTM传输,所述调度PTM传输用于使所述第一小区中的UE在调度PTM传输资源上接收数据。
发送模块32,用于向所述第一小区中的UE发送所述调度PTM传输的配置信息,所述配置信息用于使所述第一小区中的UE根据所述配置信息的指示接收数据;根据所述配置信息的指示在所述调度PTM传输资源上发送数据。
具体地,本实施例提供的基站应用于如图2所示的MBMS的系统架构。其中基站包括处理模块31和发送模块32。处理模块31用于确定在第一小区启动调度PTM传输,发送模块32用于向所述第一小区中的UE发送所述调度PTM传输的配置信息、根据所述配置信息的指示在所述调度PTM传输资源上发送数据。
由于目前的MBMS技术中,当需要进行PTM传输时,所有基站都将从BMSC接收广播组播数据,每个基站都将在提供的所有小区发送该广播组播数据,资源利用率不高。而本实施例提供的基站中,首先由处理模块31确定了在第一小区启动调度PTM传输,然后发送模块32向第一小区中的UE发送所述调度PTM传输的配置信息,最后发送模块32才在调度PTM传输资源上发送数据。从而能够以小区为粒度进行PTM传输,而无需在整个网络中都进行PTM传输。其中调度PTM传输用于使所述第一小区中的UE在调度PTM传输资源上接收数据,也就是说,调度PTM传输的目的就是以小区为粒度进行PTM传输。一个基站可能提供多个小区,确定模块31可以根据每一小区中的UE的状态,例如UE的数据、UE的需求或其他特定条件确定是否在某一小区启动调度PTM传输。
由于调度PTM传输是针对于第一小区的UE进行的,因此和图2所示的MBMS不同,当处理模块31确定了在第一小区启动PTM传输后,基站还需要通知第一小区的UE将要进行PTM传输。其中,发送模块32首先向第一小区中的UE发送调度PTM传输的配置信息,调度PTM传输的配置信息使第一小区的UE获知基站将要进行调度PTM传输,并且获知接收调度PTM传输数据的相关配置信息。然后发送模块32才能根据所述配置信息的指示在调度PTM传输资源上发送数据。
由于本实施例提供的基站是以小区为粒度进行PTM传输的,当基站确定某一小区无需进行PTM传输时,将不在该小区启动调度PTM传输,从而该小区无需为PTM传输分配传输资源,从而节约了传输资源,提高了资源利用率。
本实施例提供的基站,通过确定在第一小区启动调度PTM传输,然后向第一小区中的UE发送调度PTM传输的配置信息,并根据所述配置信息的指示在调度PTM传输资源上发送数据,从而使得基站能够以小区为粒度进行 PTM传输,节约了传输资源,提高了资源利用率。
图4为本发明实施例提供的基站实施例二的结构示意图,如图4所示,本实施例的基站在图3的基础上,还包括:
接收模块33,用于接收MBMS网关发送的数据。
发送模块32,还用于在根据所述配置信息的指示在调度PTM传输资源上发送数据之前,向MBMS网关发送组播加入请求消息。
具体地,当处理模块31确定了在第一小区启动调度PTM传输后,若基站已经在别的小区启动了调度PTM传输,则基站已经接收到了从MBMS网关发送的PTM数据,并通过发送模块32向别的小区发送该PTM数据。这种情况下,当处理模块31确定了在第一小区启动调度PTM传输,则基站可以直接将从MBMS网关接收到的PTM数据通过发送模块32在第一小区发送。
若基站还未在别的小区启动调度PTM传输,则发送模块32在根据所述配置信息的指示在调度PTM传输资源上发送数据之前,还需要向MBMS网关发送组播加入请求消息。也就是说,若基站没有在任何小区启动调度PTM传输,则基站首先需要通过发送模块32向MBMS网关发送组播加入请求消息,请求加入组播业务。然后接收模块33会接收到MBMS网关发送的数据,该数据为PTM数据。此时发送模块32才能够在根据所述配置信息的指示在调度PTM传输资源上发送从MBMS网关接收到的数据。
本实施例提供的基站在图3所示实施例的基础上,解决了还未加入组播业务的基站进行组通信的问题。
需要说明的是,图3或图4所示实施例中,处理模块31确定在第一小区启动调度PTM传输的触发条件可能有多种,以下分别逐一进行说明。
第一种情况是上级网络设备确定在第一小区启动PTM传输,基站根据上级网络设备的指示,在第一小区启动PTM传输。其中,上级网络设备包括MCE、移动管理实体(Mobility Management Entity,MME)、应用服务器等。
这种情况下,接收模块33,还用于在处理模块31确定在第一小区启动调度PTM传输之前,接收上级网络设备发送的第一小区调度PTM传输启动通知消息;处理模块31,具体用于当接收模块33接收到所述第一小区调度PTM传输启动通知消息时,确定在所述第一小区启动调度PTM传输。
具体地,上级网络设备进行UE位置信息的收集,上级网络设备根据收 集的UE的位置信息确定是否需要启动PTM传输。上级网络设备可以获知每一小区的覆盖范围,从而可以根据收集的UE的位置信息确定UE所处的小区。上级网络设备可以根据每一小区中UE的数量确定是否在该小区启动调度PTM传输,若某一小区中UE的数量超过一预设阈值,即可确定在该小区启动调度PTM传输。接收模块33接收到上级网络设备发送的第一小区调度PTM传输启动通知消息后,处理模块31即可确定在第一小区启动调度PTM传输。由于上级网络设备是根据第一小区中的UE数量确定是否在第一小区启动调度PTM传输,当第一小区中的UE数量超过预设阈值时才通知基站在第一小区启动调度PTM传输的。因此当某一小区中UE数量过少或没有UE时,则基站不会收到上层网络设备发送的调度PTM传输的启动通知消息,从而避免了在没有UE或UE数量过少的小区启动PTM传输而导致的资源效率过低的问题。
进一步地,接收模块33,具体用于接收所述上级网络设备发送的MBMS任务启动消息,所述MBMS任务启动消息包括所述第一小区调度PTM传输启动通知消息,所述第一小区调度PTM传输启动通知消息携带所述第一小区的标识信息或者调度PTM传输指示信息。也就是说,上级网络设备通知基站启动调度PTM传输的方式可以是向基站发送MBMS任务启动(MBMS session start)消息。可选地,可以在MBMS任务启动消息中携带第一小区的标识信息或者调度PTM传输指示信息,从而使接收模块33接收到上级网络设备发送的MBMS任务启动消息后,确定模块31确定在第一小区启动调度PTM传输。
第二种情况是上级网络设备收集UE的信息,基站接收上级网络设备发送的UE的信息,基站根据UE的信息确定在第一小区启动PTM传输。
这种情况下,接收模块33,还用于在处理模块31确定在第一小区启动调度PTM传输之前,接收上级网络设备发送的所述第一小区中的UE信息;处理模块31,具体用于若所述第一小区中的UE的数量超过预设阈值,则确定在所述第一小区启动调度PTM传输。
具体地,上级网络设备进行UE信息的收集,该信息包括但不限于UE的位置信息。上级网络设备将收集到的UE的信息发送给为UE提供服务的基站。基站中的接收模块33接收到上级网络设备发送的UE的信息后,可以确 定哪些UE是位于第一小区内。然后处理模块31对第一小区中的UE的数量进行判断,当第一小区中的UE的数量超过一预设阈值时,则处理模块31确定在第一小区启动调度PTM传输。由于基站中的处理模块31是根据第一小区中的UE数量确定是否在第一小区启动调度PTM传输,当第一小区中的UE数量超过预设阈值时才确定在第一小区启动调度PTM传输的。因此当某一小区中UE数量过少或没有UE时,则处理模块31不会确定在该小区启动PTM传输,从而避免了在没有UE或UE数量过少的小区启动PTM传输而导致的资源效率过低的问题。
第二种情况是基站服务的各UE向基站发送其感兴趣的组业务信息,基站根据UE上报的其感兴趣的组业务信息确定在第一小区启动PTM传输。
这种情况下,接收模块33,还用于在处理模块31确定在第一小区启动调度PTM传输之前,接收所述第一小区的UE发送的第一信息,所述第一信息包括所述UE期望接收的组业务信息;处理模块31,具体用于若所述第一小区的UE发送的第一信息中相同的期望接收的组业务信息的数量超过预设阈值,则确定在所述第一小区启动调度PTM传输,所述调度PTM传输用于传输所述数量超过预设阈值的期望接收的组业务信息。
具体地,基站服务的各UE都可以向基站发送其感兴趣的组业务信息,例如语音类信息、文字类信息、视频类信息等,或者按照其它分类方式分类的组业务信息,将该信息称为第一信息。接收模块33接收到UE发送的第一信息后,将位于第一小区中的UE发送的第一信息收集起来,然后处理模块31判断在第一小区中的UE发送的第一信息中,相同的期望接收的组业务信息的数量是否超过一预设阈值,若超过,则处理模块31可以确定在第一小区的UE中,有较多用户都期望接收某一组业务信息,从而即可确定在第一小区启动调度PTM传输。并且该调度PTM传输用于传输所述数量超过预设阈值的期望接收的组业务信息。由于基站中的处理模块31是根据第一小区中的UE期望接收的组业务信息确定是否在第一小区启动调度PTM传输,当第一小区中的UE相同的期望接收的组业务信息超过预设阈值时才确定在第一小区启动调度PTM传输的。因此当某一小区中UE相同的期望接收的组业务信息数量过少或没有UE相同的期望接收的组业务信息时,则处理模块31不会确定在该小区启动PTM传输,从而避免了在没有UE或UE数量过少的小区 启动PTM传输而导致的资源效率过低的问题。
进一步地,在图4所示实施例中,接收模块33还用于接收所述第一小区的UE发送的第二信息,所述第二信息包括所述UE切换或者重选到所述第一小区之前所在的源小区的信息;发送模块32,还用于向所述发送所述第二信息的UE所在的源小区所属源基站发送第三信息,所述第三信息包括发送所述第二信息的UE的信息,所述第三信息用于使所述源基站在统计期望接收的组业务信息的数量时排除所述发送所述第二信息的UE。
具体地,在移动通信中,UE可能处于移动状态中,因此UE可能在各小区之间进行切换。结合本发明实施例的情况,基站为某一小区的UE提供组通信服务时,若该小区中的UE移动出该小区,则基站将无法为该UE提供组通信服务。在上述第二种或第三种情况中,由于是否在第一小区中启动调度PTM传输是由基站确定的,因此,若某一小区中的UE移动出该小区,则基站在统计该小区的UE的数量或统计UE期望接收的组业务信息时,需要排除移动出该小区的UE。这里提供一种具体地实施方法,基站中的接收模块33还用于接收第一小区中的UE发送的第二信息,该第二信息包括所述UE切换或者重选到所述第一小区之前所在的源小区的信息。即基站获取第一小区中的UE在切换或者重选到第一小区之前所在的源小区的信息。然后发送模块32向发送第二信息的UE所在的源小区发送第三信息,该第三信息包括发送第二信息的UE的信息。当该源小区接收到第三信息后,即可确定第三信息中包括的发送第二信息的UE已经移动或者重选到了第一小区,则该源基站在统计期望接收的组业务信息的数量、或者统计小区中UE的数量时排除所述发送所述第二信息的UE。
进一步地,图3或图4所示实施例中,所述调度PTM传输的配置信息,包括:调度PTM传输的无线网络临时标识(Radio Network Tempory Identity,RNTI)、调度PTM传输对应的广播组播临时标示Temporary Multicast Group Identity,TMGI)、和/或所述调度PTM传输使用的资源配置信息;所述调度PTM传输的RNTI用于指示UE所述调度PTM传输所使用的RNTI,所述调度PTM传输对应的TMGI用于指示所述调度PTM传输的RNTI调度的MBMS业务标识,所述调度PTM传输使用的资源配置信息包括所述调度PTM传输使用的子帧和/或频率资源配置信息。第一小区中的UE接收到基站发送的上 述信息即可确定基站需要进行调度PTM传输,并且使用相应的标识和资源接收基站发送的数据。
进一步地,图3或图4所示实施例中,处理模块31还用于在发送模块32向所述第一小区中的UE发送所述调度PTM传输的配置信息之前,确定所述第一小区相邻小区的调度PTM传输的业务列表;发送模块32,具体用于向所述第一小区中的UE发送所述调度PTM传输的配置信息以及所述第一小区相邻小区的调度PTM传输的业务列表。
具体地,由于UE可能处于移动状态,因此,第一小区中的UE可能移动至第一小区相邻的小区中。当第一小区中的UE正在接收基站发送的调度PTM传输数据时,若该UE移动至第一小区相邻的小区,则该UE可能无法继续接收调度PTM传输数据。为了解决这个问题,处理模块31还用于在发送模块32向所述第一小区中的UE发送所述调度PTM传输的配置信息之前,确定所述第一小区相邻小区的调度PTM传输的业务列表。第一小区相邻小区的调度PTM传输业务列表中包括第一小区相邻小区正在发送的PTM传输业务数据。第一小区中的UE接收到第一小区相邻小区的调度PTM传输的业务列表后,当UE移动到第一小区相邻小区,则若该相邻小区也正在进行调度PTM传输并且调度PTM传输的业务与第一小区中的调度PTM传输业务相同,则UE可以直接在该相邻小区继续接收调度PTM数据。
进一步地,图3或图4所示实施例中,发送模块32,具体用于通过系统信息向所述第一小区中的UE广播所述调度PTM传输的配置信息;或者通过专用消息向所述第一小区中的UE发送所述调度PTM传输的配置信息。
进一步地,图3或图4所示实施例中,发送模块32,还用于在通过系统信息向所述第一小区中的UE广播所述调度PTM传输的配置信息之前,通过寻呼消息通知所述第一小区的UE从所述系统信息中读取所述调度PTM传输的配置信息,所述寻呼消息使用所述调度PTM传输的RNTI或者所述寻呼消息包括读取调度PTM传输的所述配置信息的指示。
具体地,若发送模块32需要通过系统信息向第一小区中的UE广播所述调度PTM传输的配置信息,则在此之前,发送模块32还需要通过寻呼(paging)消息通知第一小区的UE从系统信息中读取调度PTM传输的配置信息。由于基站广播的系统信息中包括的内容较多,并且是向基站服务的所 有UE广播发送的,因此在处理模块31确定在第一小区中启动调度PTM传输后,发送模块32需要向第一小区中的UE发送寻呼消息,通知UE在系统信息中读取调度PTM传输的配置信息。然后基站通过系统信息向第一小区中的UE广播所述调度PTM传输的配置信息,第一小区中的UE才能够从系统信息中获取调度PTM传输的配置信息。
图5为本发明实施例提供的UE实施例一的结构示意图,如图5所示,本实施例的UE包括:
接收模块51,用于接收基站发送的调度PTM传输的配置信息。
处理模块52,用于根据所述配置信息的指示确定接收所述基站在调度PTM传输资源上发送的数据。
接收模块51,还用于根据所述配置信息的指示接收所述基站在调度PTM传输资源上发送的数据。
具体地,本实施例提供的UE应用于如图2所示的MBMS的系统架构。其中UE包括接收模块51和处理模块52。
由于目前的MBMS技术中,当基站确定需要进行PTM传输时,所有基站都将从BMSC接收广播组播数据,每个基站都将在提供的所有小区发送该广播组播数据,基站服务的所有UE都会接收到该广播组播数据,资源利用率不高。而本实施例提供的UE中,首先由处理模块31接收基站发送的调度PTM传输的配置信息,当处理模块52根据所述配置信息的指示确定接收所述基站在调度PTM传输资源上发送的数据后,接收模块51再根据所述配置信息的指示接收所述基站在调度PTM传输资源上发送的数据。也就是说,并不是基站进行PTM传输时,其服务的所有UE都会接收到PTM传输数据,而是UE首先接收基站发送的调度PTM传输的配置信息,该基站发送的调度PTM传输的配置信息是基站确定了在第一小区启动调度PTM传输,然后向第一小区中的UE发送的。基站是以小区为粒度进行PTM传输的,而无需在整个网络中都进行PTM传输。其中调度PTM传输用于使所述第一小区中的UE在调度PTM传输资源上接收数据,也就是说,调度PTM传输的目的就是以小区为粒度进行PTM传输。
由于本实施例提供的基站是以小区为粒度进行PTM传输的,当基站确定某一小区无需进行PTM传输时,将不在该小区启动调度PTM传输,该小区 中的UE将不会接收到基站发送的调度PTM传输的配置信息,从而该小区无需为PTM传输分配传输资源,从而节约了传输资源,提高了资源利用率。
本实施例提供的UE,通过接收基站发送的调度PTM传输的配置信息,然后根据所述配置信息的指示确定接收所述基站在调度PTM传输资源上发送的数据,最后根据所述配置信息的指示接收所述基站在调度PTM传输资源上发送的数据,从而能够灵活地进行PTM传输,节约了传输资源,提高了资源利用率。
图6为本发明实施例提供的UE实施例二的结构示意图,如图6所示,本实施例的UE在图5的基础上,还包括:
发送模块53,用于在接收模块51接收基站发送的调度PTM传输的配置信息之前,向所述基站发送第一信息,所述第一信息包括所述用于设备UE期望接收的组业务信息,所述第一信息用于使所述基站根据所述UE所在小区中各UE发送的第一信息确定是否在所述UE所在小区启动调度PTM传输。
具体地,UE中的发送模块53可以向基站发送其感兴趣的组业务信息,例如语音类信息、文字类信息、视频类信息等,或者按照其它分类方式分类的组业务信息,将该信息称为第一信息。在接收模块51接收基站发送的调度PTM传输的配置信息之前,发送模块53向基站发送第一信息后,基站将位于该UE所在的小区中的所有UE发送的第一信息收集起来,然后基站判断在该小区中的UE发送的第一信息中,相同的期望接收的组业务信息的数量是否超过一预设阈值,若超过,则基站可以确定在第一小区的UE中,有较多用户都期望接收某一组业务信息,从而即可确定在第一小区启动调度PTM传输。并且该调度PTM传输用于传输所述数量超过预设阈值的期望接收的组业务信息。由于基站是根据第一小区中的UE期望接收的组业务信息确定是否在第一小区启动调度PTM传输,当第一小区中的UE相同的期望接收的组业务信息超过预设阈值时才确定在第一小区启动调度PTM传输的。因此当某一小区中UE相同的期望接收的组业务信息数量过少或没有UE相同的期望接收的组业务信息时,则基站不会确定在该小区启动PTM传输,从而避免了在没有UE或UE数量过少的小区启动PTM传输而导致的资源效率过低的问题。
进一步地,在图6所示实施例中,发送模块53,还用于向所述基站发送第二信息,所述第二信息包括所述UE切换或者重选到所述UE所在小区之前 所在的源小区的信息,所述第二信息用于使所述基站向所述UE所在的源小区所属源基站发送第三信息,所述第三信息包括所述UE的信息,所述第三信息用于使所述源基站在统计期望接收的组业务信息的数量时排除所述UE。
具体地,在移动通信中,UE可能处于移动状态中,因此UE可能在各小区之间进行切换。结合本发明实施例的情况,基站为某一小区的UE提供组通信服务时,若该小区中的UE移动出该小区,则基站将无法为该UE提供组通信服务。因此,UE中的发送模块53,还用于向所述基站发送第二信息,该第二信息包括所述UE切换或者重选到所述第一小区之前所在的源小区的信息。当基站接收到该第二信息后,再向发送第二信息的UE所在的源小区发送第三信息,该第三信息包括发送第二信息的UE的信息。当该源小区接收到第三信息后,即可确定第三信息中包括的发送第二信息的UE已经移动或者重选到了第一小区,则该源基站在统计期望接收的组业务信息的数量、或者统计小区中UE的数量时排除所述发送所述第二信息的UE。
进一步地,图5或图6所示实施例中,所述调度PTM传输的配置信息,包括:所述调度PTM传输的RNTI、所述调度PTM传输对应的TMGI、和/或所述调度PTM传输使用的资源配置信息;所述调度PTM传输的RNTI用于指示UE所述调度PTM传输所使用的RNTI,所述调度PTM传输对应的TMGI用于指示所述调度PTM传输的RNTI调度的MBMS业务标识,所述调度PTM传输使用的资源配置信息包括所述调度PTM传输使用的子帧和/或频率资源配置信息。
进一步地,图5或图6所示实施例中,处理模块52,具体用于根据所述调度PTM传输对应的TMGI确定接收所述基站在调度PTM传输资源上发送的数据;根据所述调度PTM传输的RNTI确定接收所述基站在调度PTM传输资源上发送的数据所使用的RNTI;接收模块51,具体用于根据所述RNTI在所述调度PTM传输使用的资源配置信息所指示的传输资源上接收所述基站在调度PTM传输资源上发送的数据。
进一步地,图5或图6所示实施例中,接收模块51,具体用于接收所述基站发送的调度PTM传输的配置信息以及所述UE所在小区相邻小区的调度PTM传输的业务列表;处理模块52,还用于确定所述UE所在小区相邻小区是否正在发送调度PTM传输数据;当所述UE从所述UE所在小区移动至所 述UE所在小区相邻小区时,根据所述UE所在小区相邻小区是否正在发送调度PTM传输数据确定继续通过调度PTM传输接收数据或者触发单播承载建立。
具体地,由于UE可能处于移动状态,因此,UE可能移动至其所在小区相邻的小区中。当UE正在接收基站发送的调度PTM传输数据时,若该UE移动至其相邻的小区,则该UE可能无法继续接收调度PTM传输数据。为了解决这个问题,UE中的接收模块51在接收所述基站发送的调度PTM传输的配置信息时,还用于接收基站发送的所述UE所在小区相邻小区的调度PTM传输的业务列表。UE所在小区相邻小区的调度PTM传输业务列表中包括UE所在小区相邻小区正在发送的PTM传输业务数据。接收模块51接收到UE所在小区相邻小区的调度PTM传输的业务列表后,处理模块52即可确定所述UE所在小区相邻小区是否正在发送调度PTM传输数据。当UE移动到所在小区相邻小区时,则若该相邻小区也正在进行调度PTM传输并且调度PTM传输的业务与UE所在小区中的调度PTM传输业务相同,则UE可以直接在该相邻小区继续接收调度PTM数据。
进一步地,图5或图6所示实施例中,接收模块51,具体用于接收所述基站通过系统信息在所述UE所在小区中广播的所述调度PTM传输的配置信息;或者接收所述基站通过专用消息发送的所述调度PTM传输的配置信息。
进一步地,图5或图6所示实施例中,接收模块51,还用于在接收所述基站通过系统信息在所述UE所在小区中广播的所述调度PTM传输的配置信息之前,接收所述基站发送的寻呼消息,所述寻呼消息用于通知所述UE从所述系统信息中读取所述调度PTM传输的配置信息,所述寻呼消息使用所述调度PTM传输的RNTI或者所述寻呼消息包括读取调度PTM传输的所述配置信息的指示。
具体地,若接收模块51需要接收基站通过系统信息广播的所述调度PTM传输的配置信息,则在此之前,接收模块51还需要通过寻呼(paging)消息获知基站在系统信息中发送了所述调度PTM传输的配置信息,从而从系统信息中读取调度PTM传输的配置信息。由于基站广播的系统信息中包括的内容较多,并且是向基站服务的所有UE广播发送的,因此接收模块51接收所述基站通过系统信息在所述UE所在小区中广播的所述调度PTM传输的配置信 息之前,还需要接收所述基站发送的寻呼消息,所述寻呼消息用于通知所述UE从所述系统信息中读取所述调度PTM传输的配置信息,所述寻呼消息使用所述调度PTM传输的RNTI或者所述寻呼消息包括读取调度PTM传输的所述配置信息的指示。
