Description

一种随机接入方法及相关装置
技术领域
本发明涉及通信技术领域, 具体涉及一种随机接入方法及相关装置。 背景技术
在长期演进 ( Long Term Evolution , LTE) 系统中, 用户设备 ( User
Equipment, UE) 向基站 (Evolved Node B, eNB) 发起呼叫连接比如说无线 资源控制协议 (Radio Resource Control , RRC) 连接的原因可能是主叫类型的, 也可能是被叫 (mobile terminating calls) 类型的。
eNB会对发起主叫类型的呼叫连接请求的 UE进行接入控制, 比如说, 可以根据预先依照用户类型设置的用户接入等级 (access class , AC) 设置不 同的接入控制禁止 (access control barring, ACB) 参数, 每当有 UE作为主叫 方向 eNB发起主叫类型的呼叫连接请求时, UE必须根据之前 eNB为其配置 的对应 AC等级的 ACB参数判断 eNB下的小区是否被允许接入, UE只有在 满足对应的 ACB参数所设置的限定条件的情况下才能够被允许建立连接, 反 之本次呼叫连接请求将被禁止。
然而在现有技术中, eNB 并没有对发起被叫类型的呼叫连接请求的 UE 进行接入控制, 由此导致在网络阻塞严重或负荷较大时, 作为被叫方的 UE 由于不受接入控制而发起被叫类型的呼叫连接请求来尝试建立与 eNB 的连 接, 由此给原本就阻塞的网络侧造成更大负担。 发明内容

本发明实施例提供了一种随机接入方法及相关装置。 为了使本技术领域的人员更好地理解本发明实施例的方案, 下面结合附 图和实施方式对本发明实施例作进一步的详细说明。
本发明的技术方案至少在用户侧和基站侧均有较大的改进, 现在先从用 户侧开始对本发明的技术方案进行描述。
实施例一
请参阅图 1, 其为本发明一种随机接入方法的流程示意图, 该方法包括 以下步骤:
设置步骤 S100 : 接收基站发送的被叫特征列表, 所述被叫特征列表包括 预先设定的被叫特征值和对应被叫特征值的随机接入参数。
优选的, 接收的所述被叫特征列表包含在所述基站发送的广播消息中。 被叫特征列表是预先设定好的, 并通过基站侧发送到用户侧的, 基站侧 既可以专门单独发送被叫特征列表到用户侧, 也可以将被叫特征列表植入其 他发送到基站侧的信令或数据中发送到用户侧, 一种优选的实施方式就是将 被叫特征列表包含到广播信息中, 这样, 用户侧在正常接收基站发送的广播 信息的同时, 也接收到了随广播信息一起发送来的被叫特征列表。 对被叫特 征列表需要进一步说明的是, 所述被叫特征列表中的被叫特征值和对应的随 机接入参数有别于现有技术中的主叫优先级和对应的随机接入参数的, 主要 是以被叫有关的特征值来体现不同的优先级以及对应优先级的随机接入参 数, 也就是说, 被叫特征值的优先级越高, 则其所对应的随机接入参数使得 在进行被叫类型的随机接入时, 接入成功的概率就越大, 换句话说, 被叫特 征值的优先级与对应的随机接入参数使得随机接入成功的概率大小是成正比 的, 具体如何根据随机接入参数在被叫流程中进行操作在后续的步骤中会进 行详细的描述。
在设置完成后, 也就是说用户设备 UE 已经通过基站获得了被叫特征列 表, 该列表中嚢括了各个不同优先级的被叫特征值以及对应不同优先级的随 机接入参数, 其中, 所述被叫特征值至少可以包括被叫优先级或被叫接入类 型两种索引形式, 在后续的实施例二和实施例三中, 会分别就上述提到的被 叫特征值的两种不同形式分别进行说明。
接下来, 当被叫流程开始时, 本发明技术方案将对如何根据被叫特征列 表进行随机接入进行说明, 包括步骤:
S101 : 接收由基站发送的寻呼消息, 所述寻呼消息包括所述被叫流程对 应的被叫特征值;
这里必须说明, 从基站向用户设备发送的寻呼消息, 是先由移动性管理 实体 MME向基站发出的,而触发 MME向基站发送所述传呼消息的原因是出 现有主叫方发起向被叫方的呼叫流程。 MME将向被叫方发起被叫的类型等特 征值添加到寻呼消息中, 用于让被叫方根据被叫特征值向发起基站被叫类型 的 RRC连接请求。
S102: 根据所述寻呼消息中的被叫特征值从所述被叫特征列表中选取对 应的随机接入参数;
这一步可以理解为, 由于被叫特征值以及对应的随机接入参数都是在设 置步骤中预先设置过的, 故被叫方的用户设备只需要从设置步骤中所获取的 被叫特征列表中找到与接收到的被叫特征值相对于的随机接入参数即可。
S103 : 根据选取的所述对应的随机接入参数向基站发起随机接入过程。 这里所说的被叫流程以及随机接入过程是指用户侧在被叫时向基站发起 建立连接请求的过程, 这种建立的连接主要是指无线资源控制协议 (Radio Resource Control , RRC) 连接, 当然在不同的网络环境下还可能是其他方式 的连接, 这里不再穷举。 基于如何根据选取的随机接入参数向基站发起随机 接入过程, 会在介绍完不同类型的被叫特征值后, 单独在实施例四中进行详 细的描述。
接下来, 本实施例将从信令的走向上进一步对本发明的实施方案进行描 述, 请参阅图 2, 其为本发明一种随机接入方法的信令交互示意图:
S201 : 基站向用户设备发送被叫特征列表, 所述被叫特征列表包括预先 设定的被叫特征值和对应被叫特征值的随机接入参数。
S202 : 基站向用户设备发送寻呼消息, 所述寻呼消息中包括所述被叫流 程对应的被叫特征值。
S203 : 用户设备根据所述寻呼消息中的被叫特征值从所述被叫特征列表 中选取对应的随机接入参数。
S204: 根据选取的所述对应的随机接入参数向基站发起随机接入过程。 从本实施例可以看出, 通过预先设置与被叫参数相关的被叫特征值以及 对应的随机接入参数, 并预先发送到各个用户设备, 当需要向基站发起被叫 流程时, 用户设备通过选取并使用对应当前被叫特征值的随机接入参数进行 被叫类型的随机接入过程, 由此使得系统能够针对被叫流程进行有效的控制。
进一步的, 不同被叫特征值的优先级对应相应优先级的随机接入参数, 使得被叫特征值优先级高的用户设备的被叫类型的随机接入成功建立的可能 性更高。 实施例二
在实施例一的基础上, 本实施例会针对上述被叫特征值具体为被叫接入 类型为例进行详细的描述。 请参阅图 3, 其为本发明基于被叫接入类型的通 讯方法流程示意图, 包括:
设置步骤 S300 : 接收基站发送的被叫特征列表, 所述被叫特征列表包括 预先设定的被叫接入类型和对应被叫接入类型的随机接入参数。
优选的, 所述被叫接入类型具体包括主叫侧的业务种类或传输的数据类 型。
换句话说, 主叫侧的业务种类包括如信令业务或数据业务等; 传输的数 据类型是流媒体业务数据、 交互类游戏业务数据或后台业务数据等。
以主叫侧的业务种类来定义被叫接入类型, 首先来说, 业务种类可以比 较直观的体现出想要建立呼叫的重要程度, 其次, 便于针对性的控制, 可以 根据每个基站的业务种类的特点, 进行有机的调整。 当被叫流程开始时, 包 括步骤:
S301 : 接收由基站发送的寻呼消息, 所述寻呼消息包括所述被叫流程对 应的被叫接入类型;
或者换句话说, 主叫侧的用户设备发起呼叫请求, 所在的基站将业务类 型以及被叫侧的具体 ID发送到 MME, MME根据这些信息, 向被叫侧的基 站发送寻呼消息, 并在寻呼消息中添加主叫侧的业务类型或者说被叫接入类 型。
S302: 根据所述寻呼消息中的被叫接入类型从所述被叫特征列表中选取 对应的随机接入参数;
S303 : 根据选取的所述对应的随机接入参数向基站发起随机接入过程。 如何利用选取到的随机接入参数发起被叫类型的随机接入过程将在实施 例四中进行详细的描述。 实施例三
在实施例一的基础上, 本实施例会针对上述被叫特征值具体为被叫优先 级为例进行详细的描述。 请参阅图 4, 其为本发明基于被叫优先级的通讯方 法流程示意图, 包括:
设置步骤 S400 : 接收基站发送的被叫特征列表, 所述被叫特征列表包括 预先设定的被叫优先级和对应被叫优先级的随机接入参数。
优选的, 所述被叫优先级是根据被叫接入类型进行设定的。
需要对被叫优先级进行说明, 不同的被叫接入优先级可以是指 (优先级
1, 优先级 2, ...) , 当然也可以是其他的形式, 被叫优先级由核心网侧配置, 并通知给基站和用户。类似现有技术中对主叫侧的接入基站的等级进行划分, 被叫优先级的作用是对被叫侧接入基站的等级进行划分, 这里优选的划分被 叫优先级的依据是根据被叫类型, 或者说是依据主叫侧的信令业务或数据业 务来进行划分等级, 当然也可以是其他划分被叫优先级的方式, 本发明对此 不进行限定。
优选的, 所述被叫接入类型具体包括主叫侧的业务种类或传输的数据类 型。
当被叫流程开始时, 包括步骤:
S401 : 接收由基站发送的寻呼消息, 所述寻呼消息包括所述被叫流程对 应的被叫优先级;
或者换句话说, MME根据主叫侧的业务类型或其他与被叫侧相关的信 息, 从预先设置的被叫优先级中找到对应的被叫优先级, 并在向被叫侧的基 站发送的寻呼消息中添加上述被叫优先级。
S402: 根据所述寻呼消息中的被叫接入类型从所述被叫特征列表中选取 对应的随机接入参数;
S403 : 根据选取的所述对应的随机接入参数向基站发起随机接入过程。 如何利用选取到的随机接入参数发起被叫类型的随机接入过程将在实施 例四中进行详细的描述。 实施例四
根据上述不同方式选取到随机接入参数后, 将会在被叫流程中使用到选 取到的随机接入参数,所述随机接入参数包括回退参数、功率调整因子和 ACB 参数中任意一个或多个, 上述三个参数, 在向基站建立被叫类型的 RRC连接 的过程中均会被用到, 当然, 所述随机接入参数是用户设备在设置步骤中通 过接收基站发送的广播消息中的被叫特征列表所获取的, 而预先配置的被叫 特征列表中的各个被叫特征值所对应的随机接入参数可能是上述回退参数、 功率调整因子和 ACB参数中的任意一个或多个。 当用户设备通过接收基站发 送的寻呼消息中的被叫特征值选取出的对应的随机接入参数中并没有包括全 部随机接入参数种类时, 没有出现的随机接入参数则使用现有技术中默认配 置的。 比如说, 所选取的随机接入参数中只包括 ACB参数, 则当向基站建立 被叫类型的 RRC连接的过程中需要使用到回退参数和功率调整因子时, 则使 用现有技术中默认配置的、 不具有任何优先级别的、 与被叫特征无关的回退 参数和功率调整因子进行后续的被叫随机接入过程。
以下将分别针对不同的随机接入参数在被叫随机接入过程中起到的作用 进行描述。
第一种, 当所述随机接入参数包括回退参数时, 相应的, 所述根据选取 的所述对应的随机接入参数向基站发起随机接入过程具体为:
当随机接入失败时, 根据所述回退参数获取相应的回退时间;
在间隔所述回退时间后, 向基站发起随机接入。
同时, 不同的被叫特征值对应不同的回退参数, 当然优选的是, 当被叫 特征值的优先级越高, 其所对应的回退参数使得根据回退参数所获取的回退 时间就越短, 使得用户设备能够在更短的时间里再一次重新向基站发起被叫 随机接入, 由此在其他条件相同的情况下缩短了用户设备与基站建立被叫类 型的 RRC连接所消耗的时间, 这样, 在同等时间下, 拥有更短回退时间的被 叫类型 RRC重新尝试再次接入的次数就越多,随机接入的成功的概率就越大。
第二种, 当所述随机接入参数包括功率调整因子时, 相应的, 所述根据 选取的所述对应的随机接入参数向基站发起随机接入过程具体为:
当随机接入失败时, 根据所述功率调整因子调整下一次向基站发起随机 接入的发送功率。
不同的被叫特征值对应不同的功率调整因子, 当然优选的是, 当被叫特 征值的优先级越高, 其所对应的功率调整因子, 使得下次发送随机接入码的 发送功率就越高, 当一次被叫随机接入没有成功建立后, 用户设备在下一次 重新向基站发起被叫随机接入时所使用的发送功率就越大, 发送功率越大, 基站成功接收到该被叫随机接入的可能性就越大, 使得在其他条件相同的情 况下再一次尝试被叫随机接入被基站接收到的几率就越高, 由此在同一时间 内一定程度上提高了被叫随机接入的成功概率。
第三种, 当所述随机接入参数包括 ACB参数时, 相应的, 所述根据选取 的所述对应的随机接入参数向基站发起随机接入过程具体为:
在随机接入时,根据所述 ACB参数判断所述随机接入是否允许接入基站, 具体为:
从包含 ACB参数的固定数值范围内任选一数值, 判断所述任选一数值与 所述 ACB参数的大小;
如果所述任选一数值大于等于所述 ACB参数, 则判定所述随机接入不允 许接入基站;
如果所述任选一数值小于所述 ACB参数, 则判定所述随机接入允许接入
^站
具体的判断过程举例说明:
根据不同的被叫特征值对应不同的 ACB参数,该 ACB参数是一个处于 0 到 1之间的数, 用户设备在进行被叫随机接入过程中时, 会在 0到 1之间产 生一个随机数, 当这个随机数高于 ACB参数时, 则判断这次被叫随机接入请 求被禁止, 只能在间隔一定时间后以不同的发送功率再一次发起被叫接入请 求, 当然, 间隔一定的时间以及不同的发送功率还是根据回退参数和功率调 整因子进行设定的, 在第一种和第二种中已经进行了描述, 这里就不再赘述 了。 可见, 如果 ACB参数设置的越接近 1, 则拥有该 ACB参数的被叫随机接 入请求被允许接入基站的可能性就越大, 当 ACB参数越接近 0, 则在进行被 机接入请求越不容易被允许接入基站。
以上三种是在被叫接入过程中用户设备分别依照不同的随机接入参数进 行操作, 当通过当前被叫特征值选取的随机接入参数中包括多个类型的上述 随机接入参数组合时, 同样也可以分别依照上述对应的随机接入参数类型进 行操作
当被叫特征值的优先级越高时, 则其所对应的随机接入参数使得在进行 被叫类型的随机接入时, 接入成功的概率就越大, 优选的: 当所述被叫特征值的优先级越高时, 如果所对应的随机接入参数包括回 退参数, 则当随机接入失败时, 根据所述回退参数获取的回退时间越短; 如果所对应的随机接入参数包括功率调整因子时,则当随机接入失败时, 根据所述功率调整因子调整下一次向基站发起随机接入的发送功率越大; 如果所对应的随机接入参数包括 ACB参数时, 则在随机接入时, 所选取 的 ACB参数与固定数值范围的最大值越接近。
可见, 在同等条件下, 比如说同一时间段内, 或用户处在相同位置等情 况下, 具有被叫特征值的优先级高的用户能够成功与基站建立被叫类型的接 接的可能性越大。
从本实施例可以看出, 通过预先设置与被叫参数相关的被叫特征值以及 对应的随机接入参数, 并预先发送到各个用户设备, 当需要向基站发起被叫 流程时, 用户设备通过选取并使用对应当前被叫特征值的随机接入参数进行 被叫类型的随机接入过程, 由此使得系统能够针对被叫流程进行有效的控制。
进一步的, 不同被叫特征值的优先级对应相应优先级的随机接入参数, 使得被叫特征值优先级高的用户设备的被叫类型的随机接入成功建立的可能 性更高。 实施例五
