相关申请的交叉引用
本申请主张在2017年9月28日在中国提交的中国专利申请号No.201710899311.X的优先权，其全部内容通过引用包含于此。
技术领域
本公开涉及通信技术领域，尤其涉及一种信息传输方法、终端、网络设备及计算机可读存储介质。
背景技术
在长期演进(Long Term Evolution，LTE)的双连接(Dual Connectivity，DC)系统中，包括三种不同的承载分离类型，具体为：主小区群组(Master Cell Group，MCG)承载，分离(split)承载和辅小区群组(Secondary Cell Group，SCG)承载。如图1所示，MCG承载类型包括信令无线承载(Signalling Radio Bearers，SRB)和数据无线承载(Data Radio Bearer，DRB)，Split承载类型和SCG承载类型仅包括DRB。因此，处于双连接模式下的终端，其所需的全部信令消息只能通过MCG承载发送，而数据消息可以通过MCG承载、Split承载和SCG承载发送。其中，终端数据具体选择哪种承载进行发送可通过网络设备配置的配置参数决定。具体地，配置参数包括：上行数据分离阈值(up link-Data Split Threshold)和上行数据分离数据无线承载通过辅小区群组承载发送(up link-Data Split DRB-Via SCG)。若终端待传数据量大于或等于上行数据分离阈值，则终端数据通过split承载发送，即相应数据分别传输至对应请求的MCG分支(MCG leg)和SCG分支(SCG leg)中。若终端待传数据量小于上行数据分离阈值，且up link-Data Split DRB-Via SCG为真(True)，则终端数据通过SCG承载发送。若up link-Data Split DRB-Via SCG为假(False)，则终端数据通过MCG承载发送。
在第五代(5 th Generation，5G)通信的双连接系统中，对Split承载和SCG承载进行了增强，如图2所示，MCG承载、Split承载和SCG承载均包括了 SRB和DRB。因此，处于双连接模式下的终端，其所需的信令消息除了可通过MCG承载发送外，还可进一步通过Split承载或SCG承载发送。此外，在5G双连接系统中，还需考虑到实际终端能力的限制，终端在某个时刻只能通过MCG或SCG单独发送数据或信令消息。如图3所示，网络设备可以配置一个时分复用模式(Time Division Multiplexing pattern，TDM pattern)，包括TDM周期和持续时长(on duration)等。但是，相关技术中，网络设备配置终端发送数据或信令消息使用的MCG承载、SCG承载或split承载的准则未考虑终端能力和TDM模式的限制，可能会导致终端数据或信令消息发送时延增大或发送失败等问题，无法适用于5G双连接系统。

本申请的说明书和权利要求书中的术语“第一”、“第二”等是用于区别类似的对象，而不必用于描述特定的顺序或先后次序。应该理解这样使用的数据在适当情况下可以互换，以便这里描述的本申请的实施例例如能够以除了在这里图示或描述的那些以外的顺序实施。此外，术语“包括”和“具有”以及他们的任何变形，意图在于覆盖不排他的包含，例如，包含了一系列步骤或单元的过程、方法、系统、产品或设备不必限于清楚地列出的那些步骤或单元，而是可包括没有清楚地列出的或对于这些过程、方法、产品或设备固有的其它步骤或单元。
如图4所示，本公开实施例提供了一种信息传输方法，应用于终端侧，具体包括以下步骤：
步骤41：获取单发模式下时分复用TDM模式的第一配置参数。
其中，TDM模式下的传输模式可以是周期性的亦可以是非周期性，第一配置参数用于指示TDM模式下具体的传输方式。其中，当TDM模式下为周期性传输时，第一配置参数包括以下参数中的至少一项：TDM周期，以及组成TDM周期的第一持续时段、第二持续时段、以及第一持续时段与第二持续时段之间的切换间隔。也就是说，TDM周期的持续时长包括第一持续时段的时长、切换间隔的时长和第二持续时段的时长。当TDM模式下为非周期性传输时，第一配置参数包括以下参数中的至少一项：分别允许通过不同小区群组的无线承载进行传输的第一持续时段和第二持续时段，以及第一持续时段与第二持续时段之间的切换间隔，其中，第一持续时段可称TDM_on，第二持续时段可称为TDM_off。其中，在单发模式下，TDM周期内第一持续时段与第二持续时段通过不同的小区群组的无线承载进行信息传输。
进一步地，上述第一配置参数可以是由网络设备动态或半静态配置并发送至终端的，亦可是由协议预先定义的。
其中网络设备动态或半静态配置的方法包括系统消息广播，RRC专用信令，MAC控制单元(Control Element，CE)信令，物理层控制信令。
步骤42：若待传输信息满足预设条件，则根据第一配置参数，交替通过第一小区群组和第二小区群组的无线承载向网络设备发送待传输信息。
具体地，上述第一配置参数包括：允许通过第一小区群组的无线承载进行传输的第一持续时段，和/或允许通过第二小区群组的无线承载进行传输的第二持续时段。第一小区群组为主小区群组MCG和辅小区群组SCG中的一种，第二小区群组为MCG和SCG中的另一种。也就是说当终端待传输信息满足预设条件时，在TDM模式的限制下交替通过不同小区群组的无线承载传输待传输信息，这样可保证终端在TDM模式下的正常传输。进一步地，这里所说的待传输信息包括待传输数据信息和/或待传输信令信息。当待传输信息为待传输数据信息时，在TDM模式的限制下交替通过不同小区群组的数据无线承载DRB发送至网络设备。当待传输信息为待传输信令信息时，在TDM模式的限制下交替通过不同小区群组的信令无线承载SRB发送至网络设备。
进一步地，下面本实施例将结合具体应用场景对信息传输方法做进一步 介绍。
场景一
该场景下，本公开实施例的信息传输方法包括：获取网络设备配置的单发模式下时分复用TDM模式的第一配置参数；以及，获取网络设备配置的分离承载的第二配置参数。若待传输信息满足预设条件，则根据第一配置参数，交替通过第一小区群组和第二小区群组的无线承载向网络设备发送待传输信息。
其中，第一配置参数包括：TDM周期，以及组成TDM周期的第一持续时段(TDM_on)和第二持续时段(TDM_off)。第二配置参数包括：分离承载的第一小区群组分支和第二小区群组分支的无线承载联合发送的数据量阈值，即split承载的主小区群组MCG分支(leg)和辅小区群组SCG分支(leg)同时发送的阈值(Threshold_Split)，其中具体包括：Split SRB承载MCG leg和SCG leg同时发送的阈值(Threshold_SplitSRB)，以及Split DRB承载MCG leg和SCG leg同时发送的阈值(Threshold_SplitDRB)。其中，值得指出的是数据信息的数据量阈值与信令信息的数据量阈值可以设置为相同的值，亦可设置为不同的值。第一小区群组分支为主小区群组MCG分支(leg)和辅小区群组SCG分支(leg)中的一种，第二小区群组分支为MCG分支(leg)和SCG分支(leg)中的另一种。
其中，若待传输信息满足预设条件，则根据第一配置参数，交替通过第一小区群组和第二小区群组的无线承载向网络设备发送待传输信息的步骤具体为：若待传输信息的数据量大于或等于数据量阈值，则在第一持续时段内，通过第一小区群组分支的无线承载向网络设备发送待传输信息；间隔所述切换间隔后，在第二持续时段内，通过第二小区群组分支的无线承载向网络设备发送待传输信息。
下面以TDM模式下周期性传输为例，网络设备为终端单发送的TDM模式(或称为TDM pattern)的第一配置参数，该第一配置参数包含以下内容的至少一项：TDM持续时长(on duration)、TDM周期(TDM pattern period)，以及TDM周期内第一持续时段(TDM_on)和第二持续时段(TDM_off)的传输规则，例如当前时刻为TDM_on时，指示终端单发送通过MCG的无线 承载，当前时刻为TDM_off时，指示终端单发送通过SCG的无线承载；或者，当前时刻为TDM_on时，指示终端单发送通过SCG的无线承载，当前时刻为TDM_off时，指示终端单发送通过MCG的无线承载。进一步地，网络设备还为终端配置split承载的第二配置参数，该第二配置参数包括以下内容的至少一项：Split SRB承载MCG leg和SCG leg同时发送的阈值，以及Split DRB承载MCG leg和SCG leg同时发送的阈值。
假设网络设备配置的Split SRB承载MCG leg和SCG leg同时发送的阈值为0，也就是说只要终端有信令信息需要发送，总是允许终端通过MCG leg和SCG leg同时发送。那么当终端只支持单发时，终端则可根据TDM模式的配置在TDM周期内交替通过MCG leg和SCG leg的SRB向网络设备发送对应的信令信息。例如：在TDM周期的TDM_on期间，终端通过MCG SRB向网络设备单发送信令信息，在TDM周期的TDM_off期间，终端通过SCG SRB向网络设备单发送信令信息；或者，在TDM周期的TDM_on期间，终端通过SCG SRB向网络设备发送信令信息，在TDM周期的TDM_off期间，终端通过MCG SRB向网络设备发送信令信息。
同理，假设网络设备配置的Split DRB承载MCG leg和SCG leg同时发送的阈值为0，也就是说只要终端有数据信息需要发送，总是允许终端通过MCG leg和SCG leg同时发送。那么当终端只支持单发时，终端则可根据TDM模式的配置在TDM周期内交替通过MCG leg和SCG leg的DRB向网络设备发送对应的数据信息。例如：在TDM周期的TDM_on期间，终端通过MCG DRB向网络设备单发送数据信息，在TDM周期的DM_off期间，终端通过SCG DRB向网络设备单发送数据信息；或者，在TDM周期的TDM_on期间，终端通过SCG DRB向网络设备发送数据信息，在TDM周期的TDM_off期间，终端通过MCG DRB向网络设备发送数据信息。
以上介绍了网络设备总是允许终端在split承载下同时通过MCG leg和SCG leg的无线承载进行信息传输的方式，下面将进一步介绍数据量阈值不为0的方式。
假设网络设备配置的Split SRB承载MCG leg和SCG leg同时发送的阈值为非0的值，那么当终端只支持单发、且待传输信息的数据量大于或等于上 述阈值时，终端则可根据TDM模式的配置在TDM周期内交替通过MCG leg和SCG leg的SRB向网络设备发送对应的信令信息。例如：当终端待传输的信令信息的数据量大于上述数据量阈值时，在TDM周期的TDM_on期间，终端通过MCG SRB向网络设备单发送信令信息，在TDM周期的DM_off期间，终端通过SCG SRB向网络设备单发送信令信息。或者，当终端待传输的信令信息的数据量大于上述数据量阈值时，在TDM周期的TDM_on期间，终端通过SCG SRB向网络设备发送信令信息，在TDM周期的TDM_off期间，终端通过MCG SRB向网络设备发送信令信息。
同理，假设网络设备配置的Split DRB承载MCG leg和SCG leg同时发送的阈值为非0的值，那么当终端只支持单发、且待传输信息的数据量大于或等于上述数据量阈值时，终端则可根据TDM模式的配置在TDM周期内交替通过MCG leg和SCG leg的DRB向网络设备发送对应的数据信息。例如：当终端待传输的数据信息的数据量大于上述数据量阈值时，在TDM周期的TDM_on期间，终端通过MCG DRB向网络设备单发送数据信息，在TDM周期的DM_off期间，终端通过SCG DRB向网络设备单发送数据信息；或者，当终端待传输的数据信息的数据量大于上述数据量阈值时，在TDM周期的TDM_on期间，终端通过SCG DRB向网络设备发送数据信息，在TDM周期的TDM_off期间，终端通过MCG DRB向网络设备发送数据信息。
进一步地，第二配置参数还包括：分离承载单发的默认小区群组分支(default leg)，该默认小区群组为MCG分支和SCG分支中的一种。具体包括：Split SRB承载单发送的默认小区群组分支(default leg)以及Split DRB承载单发送的默认小区群组分支(default leg)。
进一步地，本公开实施例的信息传输方法在获取网络设备配置的分离承载的第二配置参数的步骤之后还包括：若待传输信息的数据量小于数据量阈值，则通过默认小区群组分支的无线承载向网络设备发送待传输信息。具体地，第二配置参数中的数据量阈值为非0的值，以上实施例介绍了终端待传输信息的数据量大于或等于该数据量阈值的场景，在待传输信息的数据量小于该数据量阈值时，终端通过默认小区群组分支的无线承载进行待传输信息的传输。
具体地，假设网络设备配置的Split SRB承载MCG leg和SCG leg同时发送的阈值为非0的值，那么当终端只支持单发、且待传输信息的数据量小于上述数据量阈值时，终端则通过默认的SCG leg或MCG leg的SRB向网络设备发送对应的信令信息。
同理，假设网络设备配置的Split DRB承载MCG leg和SCG leg同时发送的阈值为非0的值，那么当终端只支持单发、且待传输信息的数据量小于上述数据量阈值时，终端则通过默认的SCG leg或MCG leg的DRB向网络设备发送对应的数据信息。
进一步地，在第二配置参数中还包括：分离承载的数据无线承载DRB标识和分离承载的信令无线承载SRB标识中的至少一项。这样在split承载下，终端可通过上述信息确定待传输信息对应的具体承载标识，并通过相应的承载标识在相应承载上进行信息传输。
场景二
该场景下，本公开实施例的信息传输方法包括：获取网络设备配置的单发模式下时分复用TDM模式的第一配置参数；以及，获取网络设备配置的非分离承载的第三配置参数。若待传输信息满足预设条件，则根据第一配置参数，交替通过第一小区群组和第二小区群组的无线承载向网络设备发送待传输信息。
其中，第一配置参数包括：第一持续时段(TDM_on)和第二持续时段(TDM_off)。具体地，该第一配置参数还包含以下内容的至少一项：第一持续时段(TDM_on)和第二持续时段(TDM_off)的传输规则，例如当前时刻为TDM_on时，指示终端单发送通过MCG的无线承载，当前时刻为TDM_off时，指示终端单发送通过SCG的无线承载；或者，当前时刻为TDM_on时，指示终端单发送通过SCG的无线承载，当前时刻为TDM_off时，指示终端单发送通过MCG的无线承载。第三配置参数包括：允许在第一小区群组和第二小区群组的无线承载之间进行切换的目标信息类型；其中，目标信息类型包括：数据业务类型(如时延要求极高的业务超高可靠超低时延通信URLLC等)和信令类型中的至少一项，信令类型包括：物理层信令、介质访问控制(Media Access Control，MAC)层信令、无线资源控制(Radio Resource  Control，RRC)专用信令、非接入层(Non-Access Stratum，NAS)信令中的至少一项。
若待传输信息满足预设条件，则根据第一配置参数，交替通过第一小区群组和第二小区群组的无线承载向网络设备发送待传输信息的步骤具体为：若待传输信息的信息类型为目标信息类型，则在第一持续时段内，由第一小区群组切换至第二小区群组，并通过第二小区群组的无线承载向网络设备发送所述待传输信息；或者，在第二持续时段内，由第二小区群组切换至第一小区群组，并通过第一小区群组的无线承载向网络设备发送待传输信息。
具体地，以TDM模式下周期性传输为例，假设网络设备配置的允许在第一小区群组和第二小区群组之间切换的目标信息类型为时延要求较高的数据业务、物理层信令和/或MAC层信令时，当终端在TDM周期的TDM_on通过MCG DRB传输的期间，有需要通过SCG DRB传输待传输信息的信息类型为上述数据业务、物理层信令和MAC层信令中的任一种时，终端由MCG DRB切换至SCG DRB，并通过SCG DRB传输相关待传输信息。或者，当终端在TDM周期的TDM_on通过SCG DRB传输的期间，有需要通过MCG DRB传输待传输信息的信息类型为上述数据业务、物理层信令和MAC层信令中的任一种时，终端由SCG DRB切换至MCG DRB，并通过MCG DRB传输相关待传输信息。又或者，当终端在TDM周期的TDM_off通过SCG DRB传输的期间，有需要通过MCG DRB传输待传输信息的信息类型为上述数据业务、物理层信令和MAC层信令中的任一种时，终端由SCG DRB切换至MCG DRB，并通过MCG DRB传输相关待传输信息。又或者，当终端在TDM周期的TDM_off通过MCG DRB传输的期间，有需要通过SCG DRB传输待传输信息的信息类型为上述数据业务、物理层信令和MAC层信令中的任一种时，终端由MCG DRB切换至SCG DRB，并通过SCG DRB传输相关待传输信息。
