Description
随机无线接入方法、 设备和***
技术领域
本发明涉及移动通信技术领域, 尤其涉及一种随机无线接入方法、 设备 和***。 背景技术
在移动通信***中, 为了业务的连续性或者解决覆盖问题, 一般情况下 异***小区或者异频小区可以同覆盖布网。 例如通用移动通信*** (UMTS , Universal Mobi le Telecommunications System)小区禾口长期演进 (LTE, Long Term Evolution ) 小区共同覆盖同一区域。
在移动网络运行期间, 有时小区会突然发生故障, 例如小区突然坏掉或 者突然掉电的情况, 这时小区不能正常工作。 对用户来说, 会检测到无线链 路失败 (Radio Link Failure , RLF) , 然后重选一个新小区并发起无线链路 的重新连接过程。
用户重选到新小区后, 在开始和网络通信之前先进行同步, 这个过程由 随机接入信道 (Random Access Channel , RACH) 实现。 而在进行随机接入过 程之前,要获取以下信息:可用的分组随机接入信道(PRACH, Physical Random Access Channel ) 资源、 PRACH资源对应的反馈随机接入响应消息 (RA-RNTI , Random Access - Radio Network Temporary Identifier 前导码 (Preamble) 分组、 每个前导码分组组内可用的前同步码身份标识 (preamble ID)、 选择 preamble 组的门限条件、 用于计算消息 2 (Msg2 ) 等待时间窗口的参数、 功 率提升步长 (POWER— RAMP— STEP )、 用户进行无线接入信道接入的最大次数 ( PREAMBLE— TRANS— MAX)、 初始功率。 而上述这些信息是通过信息广播下发给 用户的。 也就是说, 用户在随机无线接入前要读***广播消息, 而读***广
播是需要花费额外时间的。 为了减少通信中断时间及丢包率, 就需要快速完 成用户与新小区的随机无线接入的过程。
现有的加快随机接入的方法是, 在切换的时候通过无线配置信息把目标 小区的随机无线接入信道信息带给用户, 用户到达目标小区后, 直接进行随 机无线接入, 不需要再去读***广播消息, 也不需要竞争方式接入。 但当原 小区突然发生了故障时, 事前不能通知新小区, 新小区就不会给用户准备资 源,并且原小区的无线链路发生了故障,用户也收不到演进基站(eNB, eNodeB) 下发的消息。 因此, 该方法不能针对原小区突然发生故障的情况, 快速完成 用户和新小区的随机无线接入。 发明内容
本发明实施例提供一种随机无线接入方法, 包括: 获取邻接小区的随机 无线接入参数; 在非切换阶段, 向用户终端发送无线资源控制消息, 该无线 资源控制消息中包含上述邻接小区的随机无线接入参数。
本发明实施例还提供一种随机无线接入装置, 包括: 接收模块, 用于获 取邻接小区的随机无线接入参数; 和发送模块, 用于向用户终端发送无线资 源控制消息, 该无线资源控制消息中包含上述邻接小区的随机无线接入参数。
本发明实施例还提供一种随机无线接入***, 包括上述随机无线接入装 置和用户终端, 其中用户终端, 用于接收所述随机无线接入装置在非切换阶 段发送的所述无线资源控制消息以获取上述邻接小区的随机无线接入参数, 并根据上述随机无线接入参数向邻接小区进行随机无线接入。
通过本发明实施例提供的上述技术方案, 在突然发生小区故障时, 用户 终端可以迅速通过邻接小区的随机无线接入参数而接入邻接小区, 提高随机 无线接入的速度和成功率, 减少通信中断时间及丢包率。 附图说明
