Description

用于发送和接收系统消息的方法、装置、用户设备及基站 技术领域
本公开涉及通信技术领域，尤其涉及一种用于发送和接收系统消息的方法、装置、用户设备及基站。
背景技术
随着无线通信技术的飞速发展，长期演进(Long Term Evolution，简称为LTE)的系统消息(System Information，简称为SI)数目增多，采用周期性广播的方式发送系统消息使得基站的功耗较大，频谱资源利用率较低。对于接入的用户设备(User Equipment，简称为UE)数目比较少的情况，周期性广播系统消息存在资源浪费的问题。为了缓解广播系统消息所带来的资源浪费和基站功耗较大的问题，运营商开始考虑通过分类发送系统消息的方式来解决上述问题。
相关技术中，在第五代移动通信技术(5th Generation，简称为5G)项目的研究讨论中，可将系统消息分为第一类系统消息和第二类系统消息，第一类系统消息可包含小区选择与接入的相关系统消息，第二类系统消息可包含除第一类系统消息之外的其他系统消息。相关技术中，仍可通过广播发送第一类系统消息；而对于第二类系统消息，则可在接收到UE发送的第二类系统消息请求后，通过限定广播或单播方式来发送该系统消息。例如，接收到UE在发送的前导序列中携带的系统消息请求后，则默认通过广播的方式来发送请求的系统消息；接收到UE在发送的连接连接建立请求中携带的系统消息请求后，则默认通过广播或单播的方式来发送请求的系统消息；接收到UE在发送的专用信令中携带的系统消息请求后，则默认通过单播的方式来发送请求的系统消息。但是，通过限定广播或单播方式来发送系统消息，发送方式不够灵活。

具体实施方式
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、完整地描述，显然，所描述的实施例仅仅是本申请一部分实施例，而不是全部的实施例。基于本申请中的实施例，本领域普通技术人员在没有做出创造性劳动前提下所获得的所有其他实施例，都属于本申请保护的范围。
图1是本申请一示例性实施例示出的一种用于发送系统消息的方法的流程图，该实施例从基站侧进行描述，如图1所示，该用于发送系统消息的方法包括：
在步骤S101中，接收至少一个UE发送的SI请求。
其中，UE可以在发送的前导序列中携带SI请求，也可以在发送的连接建立请求中携带SI请求，还可以在发送的专用无线资源控制(RRC)消息中携带SI请求，以请求某个或某些SI。
在步骤S102中，根据接收的SI请求确定每个UE所请求的SI中通过单播方式发送的第一SI集合和通过广播方式发送的第二SI集合中的至少一项。
基站在接收至少一个UE发送的SI请求后，可以通过以下方式确定每个UE所请求的SI中通过单播方式发送的第一SI集合和通过广播方式发送的第二SI集合中的至少一项。如图2所示，确定第一SI集合和第二SI集合中的至少一项的方法包括：
在步骤S1021中，统计请求接收到的SI请求中每个SI的UE数量。
例如，UE1向基站发送的SI请求是用于请求SI1，SI2和SI3，UE2向基站发送的SI请求是用于请求SI1和SI3，UE3向基站发送的SI请求是用于请求SI1和SI4，则基站根据上述SI请求统计出请求SI1的UE数量为3，请求SI2的UE数量为1，请求SI3的UE数量为2，请求SI4的UE数量为1。
在步骤S1022中，针对每个SI，若请求当前SI的UE数量小于预设数量，则确定当前SI通过单播方式发送，若请求当前SI的UE数量大于或等于预设数量，则确定当前SI通过广播方式发送。
其中，预设数量可以根据需要设置。继续上例进行描述，假设预设数量为2，则对于SI1而言，请求SI1的UE数量大于预设数量，则确定SI1通过广播方式发送，对于SI2而言，请求SI2的UE数量小于预设数量，则确定SI2通过单播方式发送，对于SI3而言，请求SI3的UE数量等于预设数量，则确定SI3通过广播方式发送，对于SI4而言，请求SI4的UE数量小于预设数量，则确定SI4通过单播方式发送。
在步骤S1023中，根据所确定的通过单播方式发送的SI以及所确定的通过广播方式发送的SI，确定每个UE所请求的SI中通过单播方式发送的第一SI集合和通过广播方式发送的第二SI集合中的至少一项。
由于已确定SI1、SI3通过广播方式发送，SI2、SI4通过单播方式发送，则确定UE1所请求的SI中通过单播方式发送的第一SI集合包括SI2，通过广播方式发送的第二SI集合包括SI1和SI3，确定UE2所请求的SI中通过广播方式发送的第二SI集合包括SI1和SI3，确定UE3所请求的SI中通过单播方式发送的第一SI集合包括SI4，通过广播方式发送的第二SI集合包括SI1。
另外，若SI请求中携带当前基站通过广播方式发送的且未被对应UE成功译码的SI标识，则基站可以将未被对应UE成功译码的SI标识对应的SI添加到对应UE的第一SI集合中。
假设，UE4向基站发送的SI请求是用于请求SI6，其中，SI6由当前基站通过广播方式发送且未被对应UE成功译码，则SI6可以位于UE4第一SI集合中。
在步骤S103中，向每个UE返回SI请求的响应消息，该响应消息中携带对应UE的第一SI集合和用于指示对应UE接收第二SI集合的指示信息中的至少一项。
在确定每个UE所请求的SI中通过单播方式发送的第一SI集合和通过广播方式发送的第二SI集合中的至少一项后，可以向对应UE返回SI请求的响应消息。对于通过单播方式发送的第一SI集合，可以将第一SI集合携带在响应消息中，以返回给对应UE，对于通过广播方式发送的第二SI集合，则可以在响应消息中携带指示信息，以用于UE根据指示信息接收第二SI集合。
其中，该指示信息可以包括但不局限于以下信息中的至少一项：第二SI集合中SI的发送方式为广播方式；统一指示或分别指示的第二SI集合中SI的监听窗口数量；以及第二SI集合中每个SI各自起始监听的广播窗口位置。
上述实施例，通过根据接收的来自至少一个UE的SI请求确定每个UE所请求的SI中通过单播方式发送的第一SI集合和通过广播方式发送的第二SI集合中的至少一项，从而可以实现向对应UE单播第一SI集合和广播第二SI集合，发送方式灵活。
图3是本申请一示例性实施例示出的一种用于接收系统消息的方法的流程图，该实施例从UE侧进行描述，如图3所示，该用于发送系统消息的方法包括：
在步骤S301中，向基站发送SI请求。
其中，该SI请求中可以携带基站通过广播方式发送的且未被当前UE成功译码的SI标识。
在步骤S302中，接收基站根据SI请求返回的SI请求的响应消息，并从该响应消息中解析出第一SI集合和用于指示当前UE接收第二SI集合的指示信息中的至少一项。
其中，第一SI集合中包含当前UE请求的SI中由基站通过单播方式发送的SI，第二SI集合中包含当前UE请求的SI中由基站通过广播方式发送的SI。
在该实施例中，该指示信息可以包括但不局限于以下信息中的至少一项：第二SI集合中SI的发送方式为广播方式；统一指示或分别指示的第二SI集合中SI的监听窗口数量； 以及第二SI集合中每个SI各自起始监听的广播窗口位置。
基站在接收到UE发送的SI请求后，可以根据来自多个UE的SI请求确定请求每个SI的UE数量；然后针对每个SI，若请求当前SI的UE数量小于预设数量，则确定当前SI通过单播方式发送，若请求当前SI的UE数量大于或等于预设数量，则确定当前SI通过广播方式发送；最后可以根据所确定的通过单播方式发送的SI以及所确定的通过广播方式发送的SI，确定每个UE所请求的SI中通过单播方式发送的第一SI集合和通过广播方式发送的第二SI集合中的至少一项。
另外，若SI请求中携带基站通过广播方式发送的且未被当前UE成功译码的SI标识，则基站可以将未被当前UE成功译码的SI标识对应的SI添加到当前UE的第一SI集合中。
在步骤S303中，若解析出指示信息，则根据该指示信息接收第二SI集合。
在该实施例中，可以获取起始监听的广播窗口，并从获取的广播窗口开始连续监听预设数量广播窗口，以接收基站通过广播方式发送的SI。
其中，起始监听的广播窗口可以根据指示信息中的广播窗口位置确定，也可以根据预先获取的广播周期确定。预设数量可以等于监听窗口数量，也可以由当前UE与基站约定。
上述实施例，通过向基站发送SI请求，接收基站根据SI请求返回的SI请求的响应消息，并从响应消息中解析出第一SI集合和用于指示当前UE接收第二SI集合的指示信息中的至少一项，其中，第一SI集合中包含当前UE请求的SI中由基站通过单播方式发送的SI，第二SI集合中包含当前UE请求的SI中由基站通过广播方式发送的SI，即UE可以接收基站通过单播方式发送的第一SI集合和通过广播方式发送的第二SI集合，接收成功率高。
图4是根据一示例性实施例示出的一种用于发送系统消息的装置的框图，该装置可以位于基站中，如图4所示，该装置包括：接收模块41、确定模块42和返回模块43。
接收模块41被配置为接收至少一个用户设备UE发送的系统消息SI请求。
其中，UE可以在发送的前导序列中携带SI请求，也可以在发送的连接建立请求中携带SI请求，还可以在发送的专用无线资源控制(RRC)消息中携带SI请求，以请求某个或某些SI。
确定模块42被配置为根据所述接收模块41接收的所述SI请求确定每个UE所请求的SI中通过单播方式发送的第一SI集合和通过广播方式发送的第二SI集合中的至少一项。
返回模块43被配置为向每个所述UE返回所述SI请求的响应消息，所述响应消息中 携带所述确定模块42确定的对应UE的第一SI集合和用于指示对应UE接收所述第二SI集合的指示信息中的至少一项。
在确定每个UE所请求的SI中通过单播方式发送的第一SI集合和通过广播方式发送的第二SI集合中的至少一项后，可以向对应UE返回SI请求的响应消息。对于通过单播方式发送的第一SI集合，可以将第一SI集合携带在响应消息中，以返回给对应UE，对于通过广播方式发送的第二SI集合，则可以在响应消息中携带指示信息，以用于UE根据指示信息接收第二SI集合。
其中，该指示信息可以包括但不局限于以下信息中的至少一项：第二SI集合中SI的发送方式为广播方式；统一指示或分别指示的第二SI集合中SI的监听窗口数量；以及第二SI集合中每个SI各自起始监听的广播窗口位置。
上述实施例，通过根据接收的来自至少一个UE的SI请求确定每个UE所请求的SI中通过单播方式发送的第一SI集合和通过广播方式发送的第二SI集合中的至少一项，从而可以实现向对应UE单播第一SI集合和广播第二SI集合，发送方式灵活。
图5是根据一示例性实施例示出的另一种用于发送系统消息的装置的框图，如图5所示，在上述图4所示实施例的基础上，确定模块42可以包括：第一确定子模块421、第二确定子模块422和第三确定子模块423。
第一确定子模块421被配置为根据所述SI请求确定请求每个SI的UE数量。
例如，UE1向基站发送的SI请求是用于请求SI1，SI2和SI3，UE2向基站发送的SI请求是用于请求SI1和SI3，UE3向基站发送的SI请求是用于请求SI1和SI4，则第一确定子模块421根据上述SI请求确定请求SI1的UE数量为3，请求SI2的UE数量为1，请求SI3的UE数量为1，请求SI4的UE数量为1。
第二确定子模块422被配置为针对每个SI，若所述第一确定子模块421确定的请求当前SI的UE数量小于预设数量，则确定所述当前SI通过单播方式发送，若所述第一确定子模块确定的请求当前SI的UE数量大于或等于所述预设数量，则确定所述当前SI通过广播方式发送。
其中，预设数量可以根据需要设置。继续上例进行描述，假设预设数量为2，则对于SI1而言，请求SI1的UE数量大于预设数量，则确定SI1通过广播方式发送，对于SI2而言，请求SI2的UE数量小于预设数量，则确定SI2通过单播方式发送，对于SI3而言，请求SI3的UE数量等于预设数量，则确定SI3通过广播方式发送，对于SI4而言，请求SI4的UE数 量小于预设数量，则确定SI4通过单播方式发送。
第三确定子模块423被配置为根据所述第二确定子模块422所确定的通过单播方式发送的SI以及所确定的通过广播方式发送的SI，确定每个UE所请求的SI中通过单播方式发送的第一SI集合和通过广播方式发送的第二SI集合中的至少一项。
由于已确定SI1、SI3通过广播方式发送，SI2、SI4通过单播方式发送，则确定UE1所请求的SI中通过单播方式发送的第一SI集合包括SI2，通过广播方式发送的第二SI集合包括SI1和SI3，确定UE2所请求的SI中通过广播方式发送的第二SI集合包括SI1和SI3，确定UE3所请求的SI中通过单播方式发送的第一SI集合包括SI4，通过广播方式发送的第二SI集合包括SI1。
另外，若SI请求中携带当前基站通过广播方式发送的且未被对应UE成功译码的SI标识，则确定模块42可以将未被对应UE成功译码的SI标识对应的SI添加到对应UE的第一SI集合中。
假设，UE4向基站发送的SI请求是用于请求SI6，其中，SI6由当前基站通过广播方式发送且未被对应UE成功译码，则SI6可以位于UE4第一SI集合中。
上述实施例，通过根据SI请求确定请求每个SI的UE数量，并针对每个SI，若请求当前SI的UE数量小于预设数量，则确定所述当前SI通过单播方式发送，若请求当前SI的UE数量大于或等于所述预设数量，则确定所述当前SI通过广播方式发送；然后根据所确定的通过单播方式发送的SI以及所确定的通过广播方式发送的SI，确定每个UE所请求的SI中通过单播方式发送的第一SI集合和通过广播方式发送的第二SI集合中的至少一项，实现方式简单。
图6是根据一示例性实施例示出的一种用于接收系统消息的装置的框图，该装置可以位于UE中，如图6所示，该装置包括：发送模块61、接收解析模块62和接收模块63。

基站在接收到UE发送的SI请求后，可以根据来自多个UE的SI请求确定请求每个SI的UE数量；然后针对每个SI，若请求当前SI的UE数量小于预设数量，则确定当前SI通过单播方式发送，若请求当前SI的UE数量大于或等于预设数量，则确定当前SI通过广播方式发送；最后可以根据所确定的通过单播方式发送的SI以及所确定的通过广播方式发送的SI，确定每个UE所请求的SI中通过单播方式发送的第一SI集合和通过广播方式发送的第二SI集合中的至少一项。
另外，若SI请求中携带基站通过广播方式发送的且未被当前UE成功译码的SI标识，则基站可以将未被当前UE成功译码的SI标识对应的SI添加到当前UE的第一SI集合中。
接收模块63被配置为若所述接收解析模块62解析出所述指示信息，则根据所述指示信息接收所述第二SI集合。
上述实施例，通过向基站发送SI请求，接收基站根据SI请求返回的SI请求的响应消息，并从响应消息中解析出第一SI集合和用于指示当前UE接收第二SI集合的指示信息中的至少一项，其中，第一SI集合中包含当前UE请求的SI中由基站通过单播方式发送的SI，第二SI集合中包含当前UE请求的SI中由基站通过广播方式发送的SI，即UE可以接收基站通过单播方式发送的第一SI集合和通过广播方式发送的第二SI集合，接收成功率高。
