图2是本申请实施例提供的通信方法的一个示意性流程图。
S210，终端设备在第一小区接收第一信息，该第一信息包括第一指示信息和/或第二配置信息。
该第一小区为终端设备的服务小区或当前小区。该第一信息是管理该第一小区的网络设备发送的。其中，第一指示信息用于指示第二配置信息与第一配置信息相同或不同，第一配置信息为第一小区提供的第一业务对应的配置信息，第二配置信息为第二小区提供的第一业务对应的配置信息。第二小区为第一小区的邻居小区。
第一小区提供第一业务，管理该第一小区的网络设备会向该第一小区中的终端设备发送该第一业务对应的配置信息，即第一配置信息。终端设备可以根据第一配置信息在第一小区中接收第一小区提供的第一业务的数据。第二小区也可以提供第一业务，管理该第二小区的网络设备(与管理第一小区的网络设备可以相同也可以不同)会向该第二小区中的终端设备发送该第一业务对应的配置信息，即第二配置信息。本申请实施例中终端设备从第一小区接收第一信息，终端设备根据该第一信息中的第一指示信息确定第一配置信息与第二配置信息相同或不同，和/或，该第一信息中的该第二配置信息，终端设备在第一小区的覆盖范围内通过从第一小区接收到的第一信息获得第二小区中第一业务对应的配置信息。也就是说，终端设备即使未进入邻居小区的覆盖范围也可以获取到邻居小区中第一业务的相关信息，使得终端设备从第一小区的覆盖范围移动至第二小区的覆盖范围后，可以根据第一信息接收第二小区提供的第一业务的数据。
本申请中，一个小区提供的第一业务可以理解为正在提供的第一业务，或者能够提供的第一业务。一个小区提供的第一业务对应的配置信息可以理解为该小区正在提供的第一业务对应的配置信息，或者该小区能够提供的第一业务对应的配置信息。
一种实施方式中，第一信息包括第一指示信息，第一指示信息指示第一配置信息与第二配置信息相同。
网络设备通过第一指示信息通知终端设备第一配置信息与第二配置信息相同，终端设备根据第一指示信息确定第一配置信息与第二配置信息相同。若终端设备由第一小区的覆盖范围移动至第二小区的覆盖范围，终端设备可以根据在第一小区接收到的该第一配置信息接收第二小区提供的第一业务的数据。
另一种实施方式中，第一信息包括第一指示信息，第一指示信息指示第一配置信息与第二配置信息不同，且第一信息包括第二配置信息。
当第一配置信息与第二配置信息不同时，网络设备通过第一指示信息通知终端设备第一配置信息与第二配置信息不同，并可以在第一信息中通知终端设备第二小区中该第一业务对应的该第二配置信息。若终端设备由第一小区的覆盖范围移动至第二小区的覆盖范围，终端设备可以根据在第一小区中获取到的该第二配置信息接收第二小区提供的第一业务的数据。
另一种实施方式中，第一指示信息指示第一配置信息与第二配置信息不同，且第一信息不包括第二配置信息。
当第一配置信息与第二配置信息不同时，网络设备通过第一指示信息通知终端设备第一配置信息与第二配置信息不同，且第一信息中不包括第二配置信息。终端设备根据该第一信息确定需要在第二小区接收第二配置信息，根据该第二配置信息接收第一业务的数据。
另一实施方式中，第一指示信息指示第一配置信息与第二配置信息不同，且第一 信息包括第二配置信息。
网络设备向终端设备发送第二小区提供的该第一业务对应的该第二配置信息，终端设备可以根据在第一小区获取的该第二配置信息接收第二小区提供的第一业务的数据。
作为示例非限定，第一业务为MBS，具体地可以是采用单小区(single cell，SC)点对多点(point to multipoint，PTM)传输方式的MBS。
可选地，该第一信息可以承载在网络设备发送的该第一小区提供的第一业务对应的传输信道信息中。
可选地，第一任务的配置信息对应的配置信息可以是以下一种或多种：
与该第一业务对应的组无线网络临时标识(group-radio network temporary identity，G-RNTI)、该第一业务的控制信道(control channel，CCH)的调度信息或该第一业务的传输信道(transport channel，TCH)的调度信息。
在具体实施中，第一指示信息可以包括但不限于以下两种指示方式：
方式一，第一指示信息包括一个比特串，该比特串用于指示第一小区的一个或多个邻居小区提供的第一业务对应的配置信息与第一配置信息相同或不同。
可选地，第一指示信息包括第一比特串，该第一比特串中的一个比特对应第一小区的一个或多个邻居小区，一个比特用于指示对应的一个或多个邻居小区提供的第一业务对应的配置信息与该第一配置信息相同或不同。
一种实施方式中，第一小区提供的第一业务对应的控制信道信息指示了Q个第一邻居小区。该第一比特串中的一个比特对应一个或多个第一邻居小区，其中，Q为大于或等于0的整数。可选地，该Q个邻居小区可以是提供单小区点对多点业务的小区。
另一种实施方式中，第一小区提供的第一业务对应的传输信道信息中包括第二信息，该第二信息指示该Q个第一邻居小区中提供第一业务的M个邻居小区。该第一比特串中的一个比特对应该M个邻居小区中的一个或多个，其中M为小于或等于N且大于或等于0的整数。可选地，该Q个邻居小区可以是提供单小区点对多点MBS的小区。
可选地，该第一比特串中的一个比特对应一个邻居小区，可选地，该第一比特串中的比特数等于第一邻居小区的个数Q，或者，该第一比特串的比特数等于第二信息指示的M个邻居小区的个数M。
例如，该第一比特串包括5个比特，一个比特对应一个邻居小区，每个比特用于指示一个邻居小区提供的第一业务对应的配置信息与该第一配置信息相同或不同。该5个比特中的1个比特与第二小区对应，用于指示第二配置信息与第一配置信息相同或不同。例如该第一业务的配置信息可以是MBS对应的G-RNTI，该第二小区对应的1比特置“1”表示第一小区中MBS对应的G-RNTI与第二小区中MBS对应的G-RNTI相同，置“0”表示不同。或者反之，该第二小区对应的1比特置“1”表示第一小区中MBS对应的G-RNTI与第二小区中MBS对应的G-RNTI不同，置“0”表示相同。如，该第一指示信息可以表示为
g-RNTI-neighbourCell BIT STRING(P)，
其中，g-RNTI-neighbourCell表示第一指示信息指示第一小区的邻居小区提供的 MBS的G-RNTI相同或不同，BIT STRING为该第一比特串，P表示第一比特串包含的比特数。可选地，P可以等于第一邻居小区的个数Q，可选地，该个数Q可以表示为SIZE(maxNeighCell-SCPTM)，即支持单小区点对多点的小区的个数，此时P可以替换为SIZE(maxNeighCell-SCPTM)即该第一指示信息可以表示为
g-RNTI-neighbourCell BIT STRING(SIZE(maxNeighCell-SCPTM))，
可选地，P可以等于第二信息指示的M个邻居小区的个数M，可选地，M可以表示为SIZE(maxNeighCell-SCPTMSupport)，即支持第一业务的M个邻居小区的个数，此时P可以替换为SIZE(maxNeighCell-SCPTMSupport)，即该第一指示信息可以表示为
g-RNTI-neighbourCell BIT STRING(SIZE(maxNeighCell-SCPTMSupport))。
再例如，如该第一业务为MBS，MBS的配置信息包括MBS对应的G-RNTI、传输信道的调度信息和控制信道的调度信息等。其中MBS的配置信息中的每一项配置信息可以采用本实施方式进行指示，即MBS的配置信息中的每一项配置信息对应一个比特串，用于指示一个邻居小区的该项配置信息与第一配置信息中的该项配置信息相同或不同，其中每一项配置信息对应的比特串均包括与第二小区对应的1个比特。指示信息可以表示如下
g-RNTI-neighbourCell BIT STRING(P)，
sc-mcch-neighbourCellscheduling BIT STRING(P)，
sc-mtch-neighbourCellscheduling BIT STRING(P)，
