在当前的协议中，终端在进行服务小区更改的时候，会进行媒体接入控制重置，即对媒体接入控制(Medium Access Control，MAC)层中的数据进行清除，如清空所有下行HARQ进程的软缓存(soft buffer)、对于每一个下行HARQ进程，认为下一个接收到的传输块(Transport Block，TB)传输为首次传输等，导致各个源服务小区的HARQ实体中存储的数据被丢弃，并增加目标服务小区的数据重传次数。
针对相关技术中存在的问题，本申请提供了一种信息处理方法，能够使终端在服务小区更换的场景下尽可能地保持数据的连续性，从而减少服务小区更改过程中HARQ buffer中有用数据被丢弃的现象，并降低目标服务小区的数据重传次数。下面结合附图，通过一些实施例及其应用场景对本申请实施例提供的信息处理方法进行详细地说明。
第一方面，参见图2所示，为本申请实施例所提供的一种信息处理方法的流程图，该方法可以包括以下步骤：
步骤S201：终端接收服务小区更改命令，所述服务小区更改命令用于指示所述终端执行服务小区更改。
其中，服务小区更改命令包括以下至少一项：切换命令、主辅服务小区更改命令、辅小区切换命令，层1或层2触发的移动性信令(L1/L2-triggerred mobility)。
步骤S202：所述终端执行服务小区更改。
需要说明的是，所述终端执行服务小区，至少包括该终端被配置的特殊小区发生变更，包括或不包括终端的辅小区发生变更，其中也包括一种场景终端被配置的辅小区可以不发生更改，即下文所指的源服务小区和目标服务小区可以有相同或不同的辅小区，源服务小区和目标服务小区主要用于在时间上区分终端执行服务小区更改前后被配置的服务小区。例如，对于终端被配置的服务小区A，该服务小区A在终端执行服务小区更改的过程中未发生更改，则在执行服务小区更改前终端被配置的服务小区A属于源服务小区，在执行服务小区更改后终端被配置的服务小区A属于目标服务小区。
步骤S203：所述终端在执行服务小区更改后，根据在目标服务小区收到的指示下行分配中的HARQ信息，从所述目标服务小区接收源服务小区的重传数据。
其中，终端从目标服务小区接收到的源服务小区的重传数据是指：由源服务小区初次发送给终端，且由于未向源服务小区的网络发送确认或在源服务小区未解码成功等原因从而需要由目标服务小区重新发送给终端的数据。可以理解的是，该重传数据包括源服务小区初次发送以及初次发送后多次重新发送给终端，但在源服务小区未成功发送，需要由目标服务小区再次重新发送给终端的数据，且所述数据是在目标服务小区一次或多次未发送成功，由目标服务小区多次重新发送给终端的数据。
在具体实施时，终端可以在执行服务小区更改后，根据HARQ信息确定目标服务小区发送的数据属于首次传输在源服务小区的重传数据还是首次传输在目标服务小区的首次传输数据，以便对首次传输在源服务小区的重传数据进行合并解码或发送确认信息。可以理解的是，本申请主要是对终端执行服务小区更改后，目标服务小区发送的数据执 行是否为首次传输在源服务小区的重传数据的判断，当目标服务小区初次在一个HARQ进程发送数据且其关联的HARQ信息指示该数据为重传数据的情况下，终端即可确定该HARQ进程上传输的重传数据为首次传输在源服务小区的重传数据。对于首次传输在目标服务小区的首次传输数据及其重传数据，终端可以根据协议约定进行常规处理，本申请对此不作限制。
步骤S204：所述终端在第一HARQ实体的第一HARQ进程的HARQ buffer中保存有所述源服务小区未被成功解码的数据的情况下，对所述源服务小区未被成功解码的数据与从所述目标服务小区接收的源服务小区的重传数据合并，并对合并后得到的数据进行解码。
其中，未被成功解码的数据是源服务小区的首次传输数据或重传数据；第一HARQ实体是指终端执行服务小区更改过程中，不清除源服务小区的第一HARQ进程的HARQ buffer中所保存数据的HARQ实体。
在具体实施时，终端在执行服务小区更改后，将从目标服务小区接收的源服务小区的重传数据和HARQ buffer中保留的源服务小区未被成功解码的数据进行合并解码，能够提升解码正确率，从而降低目标服务小区对该数据的重传次数。
由上述步骤可知，终端在执行服务小区更改的过程中会至少保留第一HARQ实体中存储的源服务小区未被成功解码的数据，并在执行服务小区更改后，将该源服务小区未被成功解码的数据与目标服务小区接收到的对应重传数据进行合并解码，能够减少服务小区更改过程中有用的数据被丢弃，并降低目标服务小区的数据重传次数。
实施方式一
本实施方式描述的是终端执行服务小区更改过程中，对于下行数据所关联信息的处理情况。根据终端执行服务小区更改的两个关键节点(终端接收到服务小区更改命令到执行服务小区更改期间、以及执行服务小区更改后)，对于下行数据所关联信息的处理可以具体分为以下三种情况。
情况1：终端接收到服务小区更改命令到执行服务小区更改期间，会对第一HARQ实体中每个第二HARQ进程中正在解码的数据继续完成解码，在完成解码后，所述终端针对所述第一HARQ实体执行第一操作，所述第一操作包括以下至少一项：
A-1项：对于从所述第一HARQ实体的第二HARQ进程的HARQ buffer中解码成功的数据，如果关联控制信令，则将所述关联控制信令的数据删除；
在具体实施时，对于解码成功的数据，终端可以判断该解码成功的数据(即协议数据单元(Protocol Data Unit，MAC PDU))中的各个MAC子协议数据单元(subProtocol Data Unit，subPDU)是否关联信令无线承载(Signalling Radio Bearer，SRB)，将关联SRB(可以是SRB1、SRB2、SRB3以及SRB4中的任一者)的各个MAC subPDU确定为关联控制信令的数据并进行删除。
A-2项：所述终端的MAC层实体向无线资源控制(Radio Resource Control，RRC) 发送第一目标指示信息，所述RRC根据第一目标指示信息，指示SRB关联的分组数据汇聚层协议(Packet Data Convergence Protocol，PDCP)和无线链路层控制协议(Radio Link Control，RLC)实体清空保存的数据，所述第一目标指示信息指示UE发生了服务小区更改；
可以理解的是，通过清空SRB关联的PDCP和RLC实体保存的数据或者删除控制信令关联的数据，可以减少终端在执行服务小区更改过程中所保留的无用数据；其中，所述第一目标指示信息还可以包括以下至少一项：指示DU服务小区更改、指示MAC层保留、指示HARQ保留、以及指示L2保留。
A-3项：对于从所述第二HARQ进程的HARQ buffer中解码成功的数据，如果关联所述源服务小区的数据无线承载关联，则将关联所述源服务小区的数据无线承载关联的数据递送给高层；
在具体实施时，对于解码成功的数据，终端可以判断该解码成功的数据中的各个MAC subPDU是否关联数据无线承载(Data Radio Bearer，DRB)，将关联DRB的各个MAC subPDU递送给高层(如RRC层)继续处理。
A-4项：保留所述第二HARQ进程的HARQ buffer中的数据以及HARQ信息。
在具体实施时，终端可以将解码失败且发送了NACK指示信息的数据保留在第一HARQ进程的HARQ buffer中，以便网络侧设备在终端执行服务小区更改后，在第一HARQ实体的第一HARQ进程上触发对该数据的重传，从而能够在终端执行服务小区更改前后保持信息的连续性，减少有用数据被丢弃的情况。
此外，终端还可以将解码成功的MAC PDU保留在第二HARQ进程的soft buffer中，并保留其HARQ信息，在终端执行服务小区更改后，该保留的数据为终端在源服务小区已经解码成功但未来得及发送ACK指示信息的数据，以便终端在目标服务小区收到对第二HARQ进程的数据进行重传地HARQ指示信息时，可以跳过对该数据的接收和/或解码和/或发往高层继续处理，并向目标服务小区地网络发送确认信息；终端还可以将解码失败的数据也存储到HARQ进程的soft buffer中，并保留其HARQ信息，其后续将作为终端在源服务小区已经解码失败但未来得及发送NACK指示信息的数据，从而能够在终端执行服务小区更改前后进一步保持信息的连续性。
情况2：终端执行服务小区更改后，会在目标服务小区继续执行数据的收发，并对接收到的源服务小区的重传数据执行合并解码或发送确认通知。
在具体实施时，终端在执行服务小区更改后，可以在物理下行控制信道的时域位置(Physical Downlink Control Channel occasion，PDCCH occasion)上监听该终端对应的小区无线网络临时标识(Cell-RadioNetworkTemporaryIdentifier，C-RNTI)加扰的下行分配(downlink assignment)。终端在监听到第一HARQ实体关联的下行分配后，从物理层接收该下行分配关联的TB，随后通过第一HARQ实体，根据该TB的HARQ信息，将TB和其HARQ信息传给相关的第一HARQ进程进行合并解码。其中，终端可以根据该下行 分配中携带的HARQ信息中的新数据指示符(New Data Indicator，NDI)判断从该TB中接收到的数据为重传数据还是首次传输数据。
在合并解码成功的情况下，终端针对合并解码后的数据执行以下至少一种操作：如果所述合并解码后的数据关联控制信令，则删除所述合并解码后的数据；如果所述合并解码后的数据关联数据无线承载DRB，则保留所述合并解码后的数据，从而删除无用数据(即源服务小区的控制信令)，并保留有用数据(即源服务小区的业务数据(DRB关联的数据))，其中，终端可以根据合并解码后的数据中的每个MAC subPDU的头部信息的逻辑信道标识(Logical Channel ID，LCID)确定该MAC subPDU是关联SRB还是DRB。
在合并解码失败的情况下，终端将从所述目标服务小区接收的源服务小区的重传数据保存在所述第一HARQ进程的HARQ buffer中，以便后续将该合并解码失败的数据与新接收的重传数据再次进行合并解码，和/或，所述终端的MAC层实体指示物理层发送对所述第一HARQ进程关联的TB中的数据的NACK指示信息，以请求网络侧设备重传数据。
在终端完成合并解码后，终端还可以根据合并解码是否成功，确定该重传数据的HARQ反馈信息(如ACK指示信息)，具体地，终端可以执行以下任一行为：
终端在所述第一HARQ进程的HARQ buffer中保存有在所述源服务小区被成功解码的数据的情况下，在从所述目标服务小区收到指示所述第一HARQ进程的重传的下行分配时，所述终端的媒体访问控制MAC层实体指示物理层发送对所述第一HARQ进程关联的传输块TB中的数据的ACK指示信息，此时终端可以跳过对该下行分配关联的重传数据的对该数据的接收和/或解码和/或发往高层继续处理，从而避免对已成功解码的数据的重传数据重复执行接收和/或解码和/或发往高层继续处理。
所述终端在对第一HARQ进程的HARQ buffer中的数据与从所述目标服务小区接收的源服务小区的重传数据合并后得到的数据解码成功的情况下，所述终端的MAC层实体指示物理层发送对所述第一HARQ进程关联的TB中的数据的ACK指示信息。可以理解的是，终端可以将HARQ buffer中解码失败的数据与对应的重传数据进行合并解码，并在合并解码成功的情况下发送ACK指示信息，从而指示网络侧设备可以在所述第一HARQ进程上发送首次传输数据。
情况3：网络侧设备向终端发送服务小区更改命令，在服务小区更改之后，根据终端发送的ACK/NACK指示信息，在该终端的源服务小区关联的第一HARQ实体的第一HARQ进程上触发首次传输或重传。
网络侧设备在所述源服务小区收到终端对来自于源服务小区的第一HARQ进程关联的TB中的数据的ACK指示信息，或，所述第一HARQ进程的HARQ buffer中的数据关联控制信令的情况下，在所述第一HARQ进程上触发首次传输。具体地，网络侧设备在知晓第一HARQ进程关联的数据已经解码成功或关联源服务小区的控制信令的情况下， 网络侧设备向所述终端发送第一下行分配，该第一下行分配包括的第一HARQ进程上的HARQ信息中的NDI翻转，以使终端接收到新的下行数据。例如，网络侧设备判定在该第一HARQ进程上之前发送的数据(该TB关联的所有MAC subPDU)全部关联SRB的情况下，则网络侧设备在该第一HARQ进程上触发首次传输，该第一下行分配包括的所述第一HARQ进程上的HARQ信息中NDI翻转。
所述网络侧设备在所述源服务小区未收到所述终端对来自于源服务小区的第一HARQ进程关联的TB中数据的ACK指示信息，或在所述源服务小区收到所述终端对来自于源服务小区的第一HARQ进程关联的TB中数据的NACK指示信息的情况下，在所述第一HARQ进程上触发重传。具体地，如果网络侧设备在小区更改之前未收到对应的ACK指示信息或收到了NACK指示信息，则网络侧设备在终端执行服务小区更改后，在对应的第一HARQ进程上触发重传，即网络侧设备向终端发送第二下行分配，该第二下行分配包括的所述第一HARQ进程上的HARQ信息中NDI不翻转，以使终端接收对应的重传数据。
实施方式二
本实施方式描述的是终端执行服务小区更改过程中，对于上行数据所关联信息的处理情况。根据网络侧设备和终端执行的行为，对于上行数据所关联信息的处理可以具体分为以下两种情况。
情况1：在服务小区更改之后，网络侧设备对源服务小区关联的解码成功的数据进行删除或保留，并根据接收到的数据，在终端的源服务小区关联的第一HARQ实体的第一HARQ进程上触发首次传输或重传。
在对源服务小区关联的解码成功的数据进行删除或保留的过程中，网络侧设备执行以下至少一项：
对第二HARQ实体的第三HARQ进程的HARQ buffer中解码成功的所述终端首次传输给所述源服务小区且重传给目标服务小区的数据，如果关联控制信令，则将所述控制信令的数据删除；
对所述第二HARQ实体的第三HARQ进程的HARQ buffer中解码成功的所述终端首次传输给所述源服务小区且重传给所述目标服务小区的数据，如果关联数据无线承载关联，则将关联数据无线承载关联的数据递送给高层。
在具体实施时，网络侧设备对于已经解码成功的首次传输在源服务小区的上行数据，判断该解码成功的上行数据包含的MAC subPDU关联SRB还是DRB，如果关联DRB，则保留，如果关联SRB，则忽略。需要说明的是，本实施例中针对的数据处理的情况包括在网络侧设备发送服务小区更改命令后，网络侧的所述第三HARQ进程中存在从源服务小区收到的数据，但未来得及解码，且在服务小区更换后，第三HARQ进程才对所述数据解码完成且未递送给高层。
在终端的源服务小区关联的第一HARQ实体的第一HARQ进程上触发首次传输或重 传的过程中，网络侧设备执行以下行为：
在所述终端执行服务小区更改前，向所述终端发送了所述第一HARQ进程的上行授权或具有所述第一HARQ进程的配置授权，且在所述源服务小区正确收到了所述终端发送的相对应的数据的情况下，网络侧设备在所述终端执行服务小区更改后在所述第一HARQ进程上触发首次传输，即在网络侧设备正确获取到终端发送的数据的情况下，网络侧设备向终端发送第一上行授权，该第一上行授权包括的第一HARQ进程上的HARQ信息中的NDI翻转，以指示终端发送新的上行数据；
在所述终端执行服务小区更改前向所述终端发送了所述第一HARQ进程的上行授权或具有所述第一HARQ进程的配置授权，且在所述源服务小区未收到所述终端发送的相对应的数据的情况下，网络侧设备在所述终端执行服务小区更改后在所述第一HARQ进程上触发重传，即在网络侧设备没有正确获取到终端发送的数据的情况下，网络侧设备向终端发送第二上行授权，该第二上行授权包括的第一HARQ进程上的HARQ信息中的NDI不翻转，以指示终端重新发送该上行数据。情况2：终端不清空第一HARQ实体中的数据，且终端的MAC层在收到服务小区更改命令时停止向物理层发送上行数据。终端在执行服务小区更改后，在物理下行控制信道的时域位置(Physical Downlink Control Channel occasion，PDCCH occasion)上监听C-RNTI加扰的上行授权(uplink grant)，并通过第一HARQ实体确定监听到的上行授权关联的第一HARQ进程。具体地，在该第一HARQ进程关联的HARQ buffer中有数据(即发往源服务小区的数据)，且HARQ信息中的NDI指示目标服务小区需要重传该数据，即监听到的上行授权中的NDI未翻转，则终端将该HARQ buffer中的数据重新发送至底层(如物理层)进行传输。
实施方式三
本实施方式描述的是如何确定和处理服务小区更改过程中需要保留的HARQ实体(即第一HARQ实体)的情况。可以通过以下两种方式确定和处理需要保留的HARQ实体。
方式1：根据约定的第一HARQ实体的定义，确定需要保留的HARQ实体。
其中，所述第一HARQ实体包括以下至少一项：
B-1项：第一源服务小区关联的HARQ实体，所述第一源服务小区满足的条件是：在服务小区更改前后均为所述终端的服务小区；
例如，终端在执行服务小区更改前，被配置的小区(包含主小区(Primary Cell，Pcell)和辅小区(Secondary Cell，Scell))为：[Pcell(Cell#1)；Scell#1，SCell#2，SCell#3]；终端在执行服务小区更改后，被配置的小区为[Pcell；Scell#A，SCell#B(Cell#1)，SCell#3]；则cell#1在服务小区更改前后均为该终端的服务小区，cell#1关联的HARQ实体为第一HARQ实体。
B-2项：非服务小区关联的HARQ实体，所述非服务小区是所述终端在收到所述服务小区更改命令之前执行小区间波束管理(Inter-Cell Beam Management，ICBM)关联的 非服务小区，且是所述服务小区更改命令中指示的需要切换至的小区；
可以理解的是，终端在执行ICBM时，能够用邻小区(即非服务小区)进行数据传输，在服务小区更改命令指示了将该邻小区切换为服务小区的情况下，终端可以将该邻小区关联的HARQ实体确定为第一HARQ实体，从而减少服务小区更改所导致的数据被丢弃的情况。
B-3项：在所述终端执行分布单元(Distributed Unit，DU)内服务小区更改的情况下，第二源服务小区关联的HARQ实体，所述第二源服务小区包括主小区、主辅小区以及辅小区中的至少一个。
可以理解的是，一个DU可以控制多个小区，该多个小区属于同一MAC层，故终端执行DU内服务小区更改时，不涉及MAC层的切换，因此可以将属于同一MAC层的第二源服务小区关联的HARQ实体分别确定为第一HARQ实体。
方式2：在终端接收到服务小区更改命令的情况下，根据协议约定或接收到的第一指示信息，确定和处理需要保留的HARQ实体。
终端根据协议约定或接收到的第一指示信息，按照第一规则对源服务小区的HARQ实体进行处理，第一指示信息用于指示在服务小区更换过程中保留源服务小区的HARQ实体。
终端根据第一规则实现对第一指示信息所指示HARQ实体的保留，可选地，对源服务小区的其它HARQ实体进行重置或保留。
所述第一规则包括以下至少一项：
将第二源服务小区的特殊小区关联的HARQ实体作为所述第一HARQ实体，并映射至目标服务小区的特殊小区；
对非源特殊小区关联的HARQ实体执行重置操作，所述重置操作包括以下至少一项：
清空HARQ实体的所有HARQ进程的HARQ buffer；
设置HARQ实体的上行HARQ进程的NDIs为数值0。
在具体实施时，终端在执行服务小区更改后，将第二源服务小区的特殊小区关联的第一HARQ实体作为目标服务小区的特殊小区关联的HARQ实体，以实现第一HARQ实体的映射，可选地，通过对非源特殊小区关联的HARQ实体执行上述重置操作，将非源特殊小区关联的HARQ实体进行删除，以便对目标服务小区的非特殊小区新建HARQ实体。
方式3：终端在接收到服务小区更改命令的情况下，将所述源服务小区关联的在第一信令中指示了映射关系的HARQ实体，映射至目标服务小区；或将所述源服务小区关联的在所述第一信令中指示了映射关系的HARQ实体，映射至所述目标服务小区，并对所述源服务小区关联的在所述第一信令中未指示映射关系的HARQ实体进行重置操作；
其中，所述目标服务小区为所述终端执行服务小区更改后的服务小区；所述第一信令包括所述服务小区更改命令，和/或RRC重配置信令。在具体实施时，所述第一信令 可以包含HARQ实体的相关信息或小区相关信息例如HARQ进程ID、小区索引、物理小区标识(Physical Cell Identifier，PCI)中的一项或多项。
可以理解的是，网络侧设备可以通过服务小区更改命令携带的第三目标指示信息，指示终端将源服务小区关联的HARQ实体确定为第一HARQ实体，以保留相关的HARQ实体，网络侧设备也可以单独发送第一信令，指示终端需映射至目标服务小区的HARQ实体，以便终端对相关HARQ实体进行保留或重置。
实施方式四
本实施方式描述的是如何在终端配置了载波聚合的情况下，实现HARQ实体映射的情况。根据源服务小区的数目和目标服务小区的数目，可以分为以下两种情况：
情况1：在所述终端配置了载波聚合，且所述源服务小区的数目小于或等于所述目标服务小区的数目的情况下，终端根据所述源服务小区的小区索引和所述目标服务小区的小区索引，将所述源服务小区关联的各个HARQ实体一一映射至所述目标服务小区，将映射至所述目标服务小区的HARQ实体确定为所述第一HARQ实体；其中，所述目标服务小区为所述终端执行服务小区更改后的服务小区。
在具体实施时，可以根据源服务小区的小区索引和目标服务小区的小区索引各自从小到大的顺序，将源服务小区关联的各个HARQ实体一一映射至目标服务小区。例如，源服务小区的小区索引为1、3、4，而目标服务小区的小区索引为3、4、6，则根据索引从小到大的顺序，将小区索引为1、3、4的源服务小区关联的HARQ实体依次映射至小区索引为3、4、6的目标服务小区。
情况2：在所述终端配置了载波聚合，且所述源服务小区的数目大于所述目标服务小区的数目的情况下，终端根据所述源服务小区的小区索引和所述目标服务小区的小区索引，将所述源服务小区关联的各个HARQ实体一一映射至所述目标服务小区，将映射至所述目标服务小区的HARQ实体确定为所述第一HARQ实体，对未映射至所述目标服务小区的HARQ实体执行重置操作。
示例性地，源服务小区的小区索引为1、3、4、7，而目标服务小区的小区索引为3、4、6，则根据索引从小到大的顺序，将小区索引为1、3、4的源服务小区关联的HARQ实体依次映射至小区索引为3、4、6的目标服务小区之后，对于小区索引为7的源服务小区的HARQ实体，没有其能够映射的目标服务小区，则将该HARQ实体执行重置操作。

其中，N为所述目标服务小区包含的小区的总数，或，N为所述目标服务小区包含的激活的小区的总数。
在具体实施时，可以将正在工作的HARQ进程数目最多的前N个HARQ实体按照正在工作的HARQ进程数目的大小进行排序，得到前N个源服务小区关联的HARQ实体，再根据该N个HARQ实体正在工作的HARQ进程数目的大小顺序、以及目标服务小区的小区索引从小到大的顺序，将该N个HARQ实体顺次映射至前N个目标服务小区；也可以按照正在工作的HARQ进程数目得到N个HARQ实体后，根据源服务小区和目标服务小区的小区索引顺序，将该N个HARQ实体一一映射至N个目标服务小区。
