Description

接入资源调整方法及装置 技术领域
本公开涉及卫星通讯领域的无线通信技术，例如涉及一种接入资源调整方法及装置。
背景技术
在卫星通讯系统中，主站通过广播的形式周期性地向系统中的所有终端发送超帧结构表(Superframe Composition Table，SCT)，然后终端根据超帧结构表中的信令接入资源在系统接入资源的占比接入卫星通讯系统，与主站进行通讯。其中，系统接入资源为卫星通讯系统反向链路的接入资源，包括信息接入资源和信令接入资源，信息接入资源用于传输用户所需要的信号，例如用户通话时的语音信号、用户上网时的数据包信号；而信令接入资源则是用于传输控制电路的信号，这些信号通常并不是用户直接需要的信号。
主站分配给终端的信令接入资源是固定的，但是固定的信令接入资源往往并不适用于卫星通讯系统中所有的通讯状态。例如，一个卫星通讯系统所支持的最大终端接入数为500个，为了保证500个终端能够同时接入系统，主站分配给终端的信令接入资源在系统接入资源的占比为10％，然后终端以10％作为信令接入资源在系统接入资源的占比接入系统。接下来，终端进入正常运营状态，当终端处于正常运营状态时，需要占用的信令接入资源将会非常小，此时，终端仅需要5％作为信令接入资源在系统接入资源的占比，就可以满足与主站的正常通讯。但是由于主站分配给终端的信令接入资源在系统接入资源的占比是固定，因此，终端仍然会以10％作为信令接入资源在系统接入资源的占比与主站进行通讯，从而造成信令接入资源的浪费。

具体实施方式
以下参照附图对实施例进行说明，在不冲突的情况下，实施例和实施例中的特征可以相互任意组合。下面将结合本公开实施例中的附图，对本公开实施例中的技术方案进行清楚、完整地描述。
实施例一
本公开实施例提供了一种接入资源调整方法，应用于主站。实际应用中，卫星通讯系统通常存在至少一个信道，本公开实施例以当前信道为例进行说明。如图1所示，所述接入资源调整方法包括以下步骤。
在步骤110中，根据预设时间段内的信道空闲比和信道误码率，获取预设时间段内的信道碰撞率。
这里，预设时间段内的信道空闲比为预设时间段内信道处于空闲的累计时长在预设时间段时长的占比，反映了信道的利用情况。预设时间段内的信道误码率反映了在预设时间段内终端向主站发送的码流的传输精确性。信道碰撞率反映了码流在信道传输过程中发生碰撞的概率。
示例的，在预设时间段内，终端发送给主站码流时，在时间上是不连续的，即预设时间段内会存在终端不会向主站发送码流信道处于空闲状态的时间。可选的，可以计算预设时间段时长与预设时间段内终端发送给主站码流的累计时长之差，作为信道处于空闲状态的累计时长。因此，可以首先根据公式(2)，获取预设时间段内的信道空闲比D，公式(2)为：D＝(t2-t1)/t2。其中，t1为预设时间段内终端发送给主站码流的累计时长，t2为预设时间段的时长。
然后，根据公式(3)，获取预设时间段内的信道误码率E，公式(3)为：E＝L1/L2，其中，L1为码流中信噪比小于或等于质量阈值的码流长度，L2为码流总长度。值得说明的是，信噪比的获取可通过本领域公知的方法来实现，。质量阈值可以根据需求进行设置
根据公式(1)，获取预设时间段内的信道碰撞率C，所述公式(1)为：C＝E*(1-D)，其中，E为预设时间段内的信道误码率，D为预设时间段内的信道空闲比。
预设时间段可以根据需求进行设置。
在步骤120中，获取当前信令接入资源在系统接入资源的占比。
示例的，当主站中存储有上一次主站分配给终端的信令接入资源在系统接入资源的占比时，可以直接获取该信令接入资源在系统接入资源的占比，作为当前信令接入资源在系统接入资源的占比。当主站中没有存储上一次主站分配给终端的信令接入资源在系统接入资源的占比时，主站可以接收终端发送给主 站的一段码流，所述码流中包括信令报文和信息报文，信令报文的长度对应于信令接入资源，信息报文的长度对应于信息接入资源，因此，信令报文的长度在所述码流总长度的占比即为当前信令接入资源在系统接入资源的占比。
在步骤130中，根据所述信道碰撞率和当前信令接入资源在系统接入资源的占比，调整分配给终端的信令接入资源。
示例的，当信道碰撞率大于或等于第一阈值时，说明信道碰撞率较高，码流在传输过程中容易发生碰撞而导致码流传输错误或码流传输时延较大，这时终端增加信令接入资源来降低信道碰撞率。与此同时，当前信令接入资源在系统接入资源的占比小于或等于第二阈值，说明主站分配给终端的信令接入资源较小，很可能无法满足所有终端同时接入系统，因此主站也增加分配给终端的信令接入资源。综上所述，当信道碰撞率大于或等于第一阈值，且当前信令接入资源在系统接入资源的占比小于或等于第二阈值时，主站可以增加分配给终端的信令接入资源。
当信道碰撞率小于或等于第三阈值时，说明信道碰撞率较低，码流在传输过程中不容易发生碰撞，主站可以适当降低分配给终端的信令接入资源。与此同时，当前信令接入资源在系统接入资源的占比大于或等于第四阈值，说明主站分配给终端的信令接入资源较大，通常会造成信令接入资源的浪费。综上所述，当信道碰撞率小于或等于第三阈值，且当前信令接入资源在系统接入资源的占比大于或等于第四阈值时，主站应该减少分配给终端的信令接入资源。
在实际应用中，第一阈值、第二阈值、第三阈值以及第四阈值可以根据需要进行设置。其中，第三阈值大于第一阈值；第四阈值小于第二阈值。
主站通过信道碰撞率和当前信令接入资源在系统接入资源的占比，动态调整分配给终端的信令接入资源，使得调整后的信令接入资源可以适用于不同的应用场景，能够避免将固定的信令接入资源分配给终端而造成的终端无法接入系统或是信令接入资源浪费的现象，从而提高了通讯系统的性能。
可选的，在根据所述信道碰撞率和当前信令接入资源在系统接入资源的占比，调整分配给终端的信令接入资源时，如果所述信道碰撞率大于或等于第一阈值，且所述当前信令接入资源在系统接入资源的占比小于或等于第二阈值，那么，将分配给终端的信令接入资源在系统接入资源的占比调整为第一占比，所述第一占比大于所述当前信令接入资源在系统接入资源的占比。
可以通过调整分配给终端的信令接入资源在系统接入资源的占比，来调整分配给终端的信令接入资源；当需要增加分配给终端的信令接入资源时，可以提高分配给终端的信令接入资源在系统接入资源的占比；当需要减少分配给终端的信令接入资源时，可以降低分配给终端的信令接入资源在系统接入资源的占比。
示例的，当信道碰撞率大于或等于第一阈值，且当前信令接入资源在系统接入资源的占比小于或等于第二阈值时，主站增加分配给终端的信令接入资源。此时，主站可以将分配给终端的信令接入资源在系统接入资源的占比调整为第一占比，由于第一占比大于当前信令接入资源在系统接入资源的占比，从而增加了分配给终端的信令接入资源。
可选的，在根据所述信道碰撞率和当前信令接入资源在系统接入资源的占比，调整分配给终端的信令接入资源时，如果所述信道碰撞率小于或等于第三阈值，且当前信令接入资源在系统接入资源的占比大于或等于第四阈值，那么，将分配给终端的信令接入资源在系统接入资源的占比调整为第二占比，所述第二占比小于所述当前信令接入资源在系统接入资源的占比；其中，所述第三阈值大于所述第一阈值；所述第四阈值小于所述第二阈值。
示例的，当信道碰撞率小于或等于第三阈值，且当前信令接入资源在系统接入资源的占比大于或等于第四阈值时，主站减少分配给终端的信令接入资源。此时，主站可以将分配给终端的信令接入资源在系统接入资源的占比调整为第二占比，由于第二占比小于当前信令接入资源在系统接入资源的占比，从而减少了分配给终端的信令接入资源。
可选的，在获取当前信令接入资源在系统接入资源的占比之前，还可以存储上一次主站分配给终端的信令接入资源在系统接入资源的占比。在获取当前信令接入资源在系统接入资源的占比时，可以获取上一次主站分配给终端的信令接入资源在系统接入资源的占比，作为当前信令接入资源在系统接入资源的占比。
示例的，主站会周期性地向终端发送信令接入资源在系统接入资源的占比，以便于终端根据该占比调整信令接入资源。例如，主站会周期性地向终端发送超帧结构表，超帧结构表中会包括信令接入资源在系统接入资源的占比。因此，当每一次主站向终端发送超帧结构表时，可以将超帧结构表中的接入资源在系 统接入资源的占比依次存储于主站的占比记录中。当需要获取当前信令接入资源在系统接入资源的占比时，可以在占比记录中获取上一次的信令接入资源在系统接入资源的占比，作为当前信令接入资源在系统接入资源的占比。
本公开实施例提供了一种接入资源调整方法，包括：根据预设时间段内的信道空闲比和信道误码率，获取预设时间段内的信道碰撞率；获取当前信令接入资源在系统接入资源的占比；以及根据所述信道碰撞率和当前信令接入资源在系统接入资源的占比，调整分配给终端的信令接入资源。相较于相关技术，主站通过信道碰撞率和当前信令接入资源在系统接入资源的占比，本公开是实施例提供的接入资源调整方法和装置，能够动态调整分配给终端的信令接入资源，使得调整后的信令接入资源可以适用于不同的应用场景，能够避免将固定的信令接入资源分配给终端而造成的终端无法接入系统或是信令接入资源浪费的现象，从而提高了通讯系统的性能。
实施例二
本公开实施例提供了一种接入资源调整方法，应用于主站，在实际应用中，卫星通讯系统通常存在至少一个信道，本公开实施例以当前信道为例进行说明。如图2所示，所述接入资源调整方法包括以下步骤。
在步骤210中，获取预设时间段内接收终端码流的累计时长，以及码流总长度，执行步骤220。
示例的，终端会在时间上不连续地向主站发送码流，因此，主站可以在预设时间段内记录每一次接收终端码流的时长以及码流长度，计算在该预设时间段内记录的所有接收终端码流的时长之和作为预设时间段内接收终端码流的累计时长；计算在该预设时间段内记录的所有的码流长度之和作为预设时间段内码流总长度。
预设时间段可以根据需要进行设置。
在步骤220中，根据预设时间段内接收终端码流的累计时长，获取预设时间段内信道空闲比，执行步骤230。
可以根据公式(2)，获取预设时间段内的信道空闲比D，公式(2)为：D＝(t2-t1)/t2，其中，t1为预设时间段内终端发送给主站码流的累计时长，t2为预设时间段的时长。
在步骤230中，根据接收的终端码流中信噪比小于或等于质量阈值的码流长度和码流总长度，获取预设时间段内信道误码率，执行步骤240。
示例的，可以根据公式(3)，获取预设时间段内的信道误码率E，公式(3)为：E＝L1/L2，其中，L1为码流中信噪比小于或等于质量阈值的码流长度，L2为码流总长度。
在步骤240中，根据信道空闲比和信道误码率，计算信道碰撞率，执行步骤250。
示例的，可以根据公式(1)，获取预设时间段内的信道碰撞率C，公式(1)为：C＝E*(1-D)，其中，E为预设时间段内的信道误码率，D为预设时间段内的信道空闲比。
在步骤250中，获取当前信令接入资源在系统接入资源的占比，执行步骤260或步骤2100。
示例的，当主站中存储有上一次主站分配给终端的信令接入资源在系统接入资源的占比时，可以直接获取该信令接入资源在系统接入资源的占比，作为当前信令接入资源在系统接入资源的占比。
值得说明的是，本公开实施例提供了两种信令接入资源调整方案，分别为增加信令接入资源调整方案和减少信令接入资源调整方案。当符合增加信令接入资源调整方案的条件时，主站增加分配给终端的信令接入资源；当符合减少信令接入资源调整方案的条件时，主站减少分配给终端的信令接入资源；当上述两个条件均不符合时，主站保持当前分配给终端的信令接入资源即可。因此，在获取当前信令接入资源在系统接入资源的占比之后，还分别判断是否符合上述两个条件。步骤260和步骤2100分别是判断是否符合上述两个条件的起始步骤。
在步骤260中，判断信道碰撞率是否大于或等于第一阈值；当信道碰撞率大于或等于第一阈值时，执行步骤270；当信道碰撞率小于第一阈值时，执行步骤2140。
当信道碰撞率大于或等于第一阈值时，说明信道碰撞率较高，终端需要增加信令接入资源来降低信道碰撞率。但是，仅由于信道碰撞率较高，就确定需要增加主站分配给终端的信令接入资源，往往不够全面，容易造成误判。示例 的，虽然信道碰撞率较高，但主站分配给终端的信令接入资源已经较多时，说明此时较高的信道碰撞率并不是由于信令接入资源不足而导致的，因此，即使增加了信令接入资源，仍然无法缓解较高的信道碰撞率，反而会降低信道利用率，进而降低系统的性能。因此，当信道碰撞率大于或等于第一阈值时，判断当前主站分配给终端的信令接入资源的情况。
在步骤270中，判断当前信令接入资源在系统接入资源的占比是否小于或等于第二阈值；若当前信令接入资源在系统接入资源的占比小于或等于第二阈值，执行步骤280；若当前信令接入资源在系统接入资源的占比大于第二阈值，执行步骤2140。
信令接入资源在系统接入资源的占比反映了主站分配给终端的信令接入资源情况；若当前信令接入资源在系统接入资源的占比较大，则当前主站分配给终端的信令接入资源较多；若当前信令接入资源在系统接入资源的占比较小，则当前主站分配给终端的信令接入资源较少。因此，若当前信令接入资源在系统接入资源的占比小于或等于第二阈值，说明当前主站分配给终端的信令接入资源较少。
因此，当信道碰撞率大于或等于第一阈值，且当前信令接入资源在系统接入资源的占比小于或等于第二阈值时，说明信道碰撞率较高，同时，当前主站分配给终端的信令接入资源较少，主站此时增加分配给终端的信令接入资源。示例的，可以生成用于增加分配给终端的信令接入资源的第一超帧结构表。
在步骤280中，生成用于增加分配给终端的信令接入资源的第一超帧结构表，执行步骤2130。
第一超帧结构表中包括第一占比，第一占比大于当前信令接入资源在系统接入资源的占比。
为了增加终端的信令接入资源，主站可以向终端发送包括第一占比的第一超帧结构表。终端按照第一超帧结构表中的第一占比接入系统，并且与主站进行通讯。由于第一占比大于终端的当前信令接入资源在系统接入资源的占比，因此，终端的信令接入资源得到了增加。进而避免了当信道碰撞率大于或等于第一阈值，且当前信令接入资源在系统接入资源的占比小于或等于第二阈值时，终端可能会出现的无法接入系统的情况。
在步骤290中，将第一超帧结构表发送给终端，本流程结束。
在步骤2100中，判断信道碰撞率是否小于或等于第三阈值；当信道碰撞率小于或等于第三阈值时，执行步骤2110；当信道碰撞率大于第三阈值时，执行步骤2140。
当信道碰撞率小于或等于第三阈值时，说明信道碰撞率较低，终端可以适当减少信令接入资源。但是，仅由于信道碰撞率较低，就确定减少主站分配给终端的信令接入资源，往往不够全面，容易造成误判。示例的，虽然信道碰撞率较低，但主站分配给终端的信令接入资源已经较少时，如果此时减少分配给终端的信令接入资源，可能会出现由于信令接入资源过少而无法满足所有终端同时接入系统的情况。因此，当信道碰撞率小于或等于第三阈值时，判断当前主站分配给终端的信令接入资源的情况。
在步骤2110中，判断当前信令接入资源在系统接入资源的占比是否大于或等于第四阈值；若当前信令接入资源在系统接入资源的占比大于或等于第四阈值，执行步骤2120；若当前信令接入资源在系统接入资源的占比小于第四阈值时，执行步骤2140。
若当前信令接入资源在系统接入资源的占比大于或等于第四阈值，说明当前主站分配给终端的信令接入资源较多。因此，当信道碰撞率小于或等于第三阈值，且当前信令接入资源在系统接入资源的占比大于或等于第四阈值时，说明信道碰撞率较低，同时，当前主站分配给终端的信令接入资源较多，主站此时可以适当减少分配给终端的信令接入资源。示例的，可以生成用于减少分配给终端的信令接入资源的第二超帧结构表。
在步骤2120中，生成用于减少分配给终端的信令接入资源的第二超帧结构表，执行步骤2130。
第二超帧结构表中包括第二占比，第二占比小于当前信令接入资源在系统接入资源的占比。
为了减少终端的信令接入资源，主站可以向终端发送包括第二占比的第二超帧结构表。然后，终端按照第二超帧结构表中的第二占比接入系统，并且与主站进行通讯。由于第二占比小于终端的当前信令接入资源在系统接入资源的占比，因此，终端的信令接入资源得到了减少，进而避免了浪费信令接入资源的情况。
在步骤2130中，将第二超帧结构表发送给终端，本流程结束。
在步骤2140中，生成用于保持分配给终端的信令接入资源的第三超帧结构表，执行步骤2150。
这里，第三超帧结构表中包括第三占比，第三占比等于当前信令接入资源在系统接入资源的占比。
为了保持终端的信令接入资源，主站可以向终端发送包括第三占比的第三超帧结构表。终端按照第三超帧结构表中的第三占比接入系统，并且与主站进行通讯。由于第三占比等于终端的当前信令接入资源在系统接入资源的占比，因此，终端的信令接入资源得到了保持。
在步骤2150中，将第三超帧结构表发送给终端，本流程结束。
需要说明的是，本公开实施例提供的接入资源调整方法步骤的先后顺序可以进行适当调整，步骤也可以根据情况进行相应增减。
本公开实施例提供了一种接入资源调整方法，相较于相关技术，主站通过信道碰撞率和当前信令接入资源在系统接入资源的占比，动态调整分配给终端的信令接入资源，使得调整后的信令接入资源可以适用于不同的应用场景，能够避免将固定的信令接入资源分配给终端而造成的终端无法接入系统或是信令接入资源浪费的现象，从而提高了通讯系统的性能。
实施例三
本公开实施例提供了一种接入资源调整装置30，如图3所示，所述装置30包括：第一获取单元301、第二获取单元302和调整单元303。

第二获取单元302，设置为获取当前信令接入资源在系统接入资源的占比。
调整单元303，设置为根据所述信道碰撞率和当前信令接入资源在系统接入资源的占比，调整分配给终端的信令接入资源。
主站通过信道碰撞率和当前信令接入资源在系统接入资源的占比，动态调整分配给终端的信令接入资源，使得调整后的信令接入资源可以适用于不同的应用场景，能够避免将固定的信令接入资源分配给终端而造成的终端无法接入系统或是信令接入资源浪费的现象，从而提高了通讯系统的性能。
可选的，调整单元303设置为：当所述信道碰撞率大于或等于第一阈值，且所述当前信令接入资源在系统接入资源的占比小于或等于第二阈值时，将分配给终端的信令接入资源在系统接入资源的占比调整为第一占比，所述第一占比大于所述当前信令接入资源在系统接入资源的占比。
