- Step 101 The terminal selects one data channel in at least one channel.
- the channels can be classified into the following two types: a signaling channel for transmitting signaling and a data channel for transmitting data information.
- the remaining resources on the signaling channel in addition to the transmission signaling can also be used to transmit data.

If the terminal does not receive the beacon frame within the preset time, or the identifier of the received beacon frame does not match the identifier of the BSS to be accessed, it indicates that the BSS to be accessed does not work on the channel.
- the main principle of active probing is that the station sends a probe request frame (Probe Request) on the channel, and then waits to receive a probe response frame (Probe Response). If the terminal does not receive the probe response frame within the preset time, or the identifier of the received probe response frame does not match the BSS to be accessed, it indicates that the BSS to be accessed does not work on this channel.

技术领域
本发明涉及通信技术， 尤其涉及一种信令信道位置确定方法及装置。 背景技术
通信系统中通常存在多种信道， 其中部分信道用于传输信令， 称为信令 信道等， 采用哪个信道作为信令信道通常由基站确定， 基站在确定信令信道 之后再将信令信道告知终端。 终端若不明确哪个信道为信令信道， 则无法进 行信令传输， 从而无法进行通信。
在现有技术中， 终端在不明确哪个信道为该终端当前所处的小区系统的 信令信道时， 会依次对各个信道进行监听， 判断当前监听的信道是否为该小 区系统的信令信道， 若是则接入信令信道接收 /发送信令； 若否， 则转入下一 个信道进行监听， 直到判断出当前所监听的信道为信令信道。
但是， 由于小区系统的工作带宽较大， 即信道的个数多， 而信令信道通 常只占用一个信道， 所以终端逐个监听所有信道直至找到信令信道的过程耗 费的时间长， 效率低， 而且会导致该终端数据传输的延迟增大。 发明内容 本发明实施例提供一种信令信道位置确定方法及装置， 以缩减终端查找 信令信道的时间， 缩减终端接入通信系统所需的时间， 提高接入效率。

为使本发明实施例的目的、 技术方案和优点更加清楚， 下面将结合本 发明实施例中的附图， 对本发明实施例中的技术方案进行清楚、 完整地描 述， 显然，所描述的实施例是本发明一部分实施例， 而不是全部的实施例。 基于本发明中的实施例， 本领域普通技术人员在没有作出创造性劳动前提 下所获得的所有其他实施例， 都属于本发明保护的范围。
通信系统通常包含多个信道， 按照信令信道和数据信道位置的不同， 信
道的设计可以分为带内设计和带外设计。 带内设计的信道均为混合信道， 每 个信道上都有信令来控制本信道甚至其它信道的数据通信； 带外设计中一部 分信道专门用于传输数据， 信令仅在部分频率信道上发送， 这部分信道即信 令信道， 而部分信令信道也可以用于传输数据， 即通常所说的混合信道。 本 发明实施例中， 将用于传输信令的信道 （包括信令信道和混合信道） 均称为 信令信道。
本发明实施例是针对带外设计的多信道的通信系统。 这类通信系统通常 包含至少一个数据信道， 以及至少一个信令信道。
本发明实施例提供的信令信道位置确定方法及装置中， 包括一种新的 查询信令信道的技术方案， 该技术方案适用于终端首次接入小区系统的过 程， 也适用于已经接入系统， 终端丢失信令信道后再次接入小区系统的过 程。
本发明实施例所述的小区由一个基站 （Base Station, 简称： BS ) 和多个 终端构成， 基站可以是接入点（Access Point, 简称： AP) 、 节点 B (Node B ) 或演进的节点 B (Evolution Node B , 简称： eNode B ) 等， 终端可以是站点 (Station, 简称： STA) 、 用户设备 （User Equipment, 简称： UE) 等， 小区 可以是基本服务集 （Basic Service Set, 简称： BSS ) 等。
本发明实施例所述的信令信道的位置， 可以理解为信令信道的标识、 信 道号、 频点等用于指示信令信道在所有信道中的位置， 或者， 信令信道所在 的频率资源在频域中的位置。
图 1为本发明信令信道位置确定方法实施例一的流程图， 本实施例的执 行主体为终端。 在本实施例中， 终端首先确定信令信道后， 在信令信道上与 基站进行信令传输， 以接入该基站所在的通信系统。 如图 1所示， 本实施例 的信令信道位置确定方法可以包括：
步骤 101、 终端在至少一个信道中选择一个数据信道。
在通信系统中通常存在多个信道， 按照各个信道的功能， 可以将信道分 为以下两类： 用于传输信令的信令信道和用于传输数据信息的数据信道。 信 令信道上除了传输信令之外如果有剩余资源也可以用于传输数据。 信令信道 和数据信道统称为工作信道。 此外， 通信系统中还可能存在非工作信道。 采 用哪个信道作为信令信道通常由基站确定， 基站在确定信令信道之后再将信
令信道告知终端。终端若不明确哪个信道为信令信道， 则无法进行信令传输， 从而无法进行通信。 导致终端不明确哪个信道为信令信道的场景例如： 基站 向终端发送了信令信道切换的信令， 但是终端没有正确接收该信令； 或者， 终端刚刚进入该基站服务范围。
而且， 工作信道中可能多数为数据信道， 少数为信令信道。 通常， 终端 接入小区系统的过程为： 首先选择一个信道， 检测该信道是否为工作信道， 若否， 则选择下一个信道， 再次进行检测， 直到所选择的信道为工作信道； 然后再查找信令信道来进行下一步的接入。 而在本实施例中， 终端在检测到 一个信道为工作信道后， 即使该工作信道为数据信道， 也可以按照后续的步 骤确定信令信道的位置。 数据信道的确认可以采用现有系统中的已有方式， 也可以采用其它方式， 只要能够使终端识别出该信道为本小区的数据信道即 可。 一种可能方式是通过对接收帧同步序列的检测获知是本系统站点在发送 信号， 然后配合接收帧中的预先设定的序列或者比特字段指示等进一步判定 该接信道是不是本小区的数据信道。 另一种可能方式是不同的小区的数据信 道采用不同的同步序列， 这样通过对接收帧的同步序列的匹配就可以直接判 断该信道是不是本小区的数据信道。 而对于终端第一次检测的信道即为信令 信道的特殊场景， 终端可以直接在该信道上读取信息以确定出该信令信道， 也可以按本实施例中的方法， 继续对信道进行检测， 直到选择一个数据信道， 再按照后续的步骤确定信令信道的位置。
需要澄清的是， 本专利的实施方案中需要在数据信道中发送信令信道指 示信息， 或者接收到终端在数据信道上发送信令信道指示请求后发送信令信 道指示信息。 虽然这里的信令信道指示信息和信令信道指示请求可以认为是 信令信息， 但是为了描述方便， 在解释本专利实施方案的过程中仍然将传输 了信令信道指示信息和信令信道指示请求的数据信道称为数据信道。
终端可以随机地选择信道， 或者根据预设的顺序选择信道， 本发明实施 例对此不作任何限定。
步骤 102、 终端在所述选择的数据信道上读取信令信道指示信息。
具体地， 信令信道指示信息可以包含信令信道的信道号， 或者其他能够 使终端确定信令信道的信息。 若该通信系统中包含多个信令信道， 则根据具 体的信令传输的需求， 该信令信道指示信息中可以包含多个信令信道的各自
信道号。
现有技术中， 终端通过信道扫描的方式来确定信令信道， 信道扫描的一 个基本过程可以是， 终端选择一个信道， 然后在该信道上通过被动监听或 者主动探测的方式来确定待接入基本服务集（Basic Service Set,简称： BSS ) 是否在该信道上， 如果终端确定该信道上不包含待接入 BSS , 则选择另一 个信道重复以上检测过程。 被动监听的主要原理是， 待接入的 BSS的 AP 或者基站会周期性地在工作信道上发送信标帧 （Beacon) ， 信标帧中包含 该 BSS的标识符和工作信道，终端根据是否收到信标帧以及信标帧中的内 容确定待接入的 BSS是否工作在该信道上。如果终端在预设时间内未接收 到信标帧， 或者所接收的信标帧的标识符与待接入的 BSS的标识符不符， 则表示待接入 BSS不工作在此信道上。主动探测的主要原理是站点在该信 道上发送探测请求帧 （Probe Request) ， 然后等待接收探测响应帧 （Probe Response ) 。 终端在预设时间内未收到探测响应帧， 或者所接收的探测响 应帧的标识符与待接入的 BSS不符， 则表示待接入的 BSS不工作在此信 道上。
举例来说，在 5 GHz频谱上的无线局域网（wireless local area network, 简称： WLAN) 可用的非授权频带 （Unlicensed Band) 为 480MHz， 而一 个信道的基本带宽 20MHz， 则终端在接入的过程中， 可能需要扫描 24个 信道， 对每个信道进行监听， 直到所监听的信道为信令信道， 导致接入过 程耗费的时间长。
而在步骤 102中，终端在所述选择的数据信道上读取信令信道指示信息， 使得终端选择到第一个数据信道后即可确定信令信道， 避免了终端对多个数 据信道进行监听后才找到信令信道的过程，节省了确定信令信道位置的时间。
具体地， 所述信令信道指示信息可以为基站按照预设的时间周期在每个 数据信道或每个工作信道上发送的， 或者， 也可以通过终端在选择的数据信 道上主动向基站发送信令信道指示请求后， 接收基站在所述选择的数据信道 上返回的响应获得的， 或者， 也可以通过其他方式使得所述选择的数据信道 包含所述信令信道指示。
步骤 103、 终端根据所述信令信道指示信息确定信令信道的位置。
终端在确定信令信道的位置之后， 就可以进行与基站之间的信令传输，
从而接入基站所在的小区系统。
本实施例， 终端通过在所选择的数据信道上读取信令信道指示信息， 使 得终端在确定出所选择的信道为数据信道后， 能够通过该数据信道获得信令 信道的信息， 从而避免了扫描多个数据信道直到确定出信令信道的过程， 从 而能够减少确定信令信道， 并接入通信系统所需的时间， 提高效率。
在本发明信令信道位置确定方法实施例二中， 在上述实施例的步骤 102 之前， 还可以包括以下步骤： 终端在至少一个数据信道上接收基站发送的指 示消息， 所述指示消息中包括信令信道指示信息。
即， 在步骤 102之前， 基站已经在部分或者全部数据信道上下发了指示 消息， 所述指示消息中包括信令信道指示信息。
进一步具体地， 上述步骤可以为： 终端在任意一个所述数据信道上接收 基站发送的指示消息。
相应地， 基站可以按照预设的时间周期， 在该小区系统的每个工作信道 或每个数据信道上广播信令信道指示信息。 这样， 终端只要确定出所选择的 信道为数据信道， 即可在该数据信道读取基站广播的指示消息中的信令信道 指示信息， 从而确定信令信道。
图 2为本发明信令信道位置确定方法实施例三的流程图， 本实施例的执 行主体为终端， 本实施例在图 1所示实施例的基础上， 增加了终端在任意一 个数据信道上与基站进行交互， 以使基站发送信令信道指示的过程。 如图 2 所示， 本实施例的方法可以包括：
步骤 201、 终端在至少一个信道中选择一个数据信道。
步骤 202、终端在所述选择的数据信道上向基站发送信令信道指示请求。 步骤 203、 终端在所述选择的数据信道上接收基站根据所述信令信道指 示请求发送的指示消息， 所述指示消息中包括信令信道指示信息。
具体地， 终端可以在所述选择的数据信道上向基站发送一个信令信道指 示的请求帧， 之后终端就在该数据信道等待接收基站回复的指示消息， 在该 指示消息中可以包含信令信道指示信息。
步骤 204、 终端在所述选择的数据信道上读取信令信道指示信息。
步骤 205、 终端根据所述信令信道指示信息确定信令信道的位置。
本实施例， 终端可以在任何一个数据信道上向基站发送信令信道指示请
求， 并根据基站回复的信令信道指示信息确定信令信道的位置， 从而避免了 扫描多个数据信道直到确定出信令信道的过程， 从而能够减少确定信令信道 的时间， 从而减少接入通信系统所需的时间， 提高效率。
图 3为本发明信令信道位置确定方法实施例四的流程图， 本实施例的执 行主体为基站。 在本实施例中， 基站发送信令信道指示信息， 以使终端确定 信令信道后， 在信令信道上与基站进行信令传输， 以接入该基站所在的通信 系统。 如图 3所示， 本实施例的信令信道位置确定方法可以包括：
步骤 301、 基站设置指示消息， 所述指示消息中包括信令信道指示信息。 步骤 302、 基站在至少一个数据信道上发送所述指示消息， 以使终端根 据所述指示消息中的信令信道指示信息确定信令信道的位置。
其中， 基站发送所述指示消息可以采用广播的方式或者单播的方式向终 端或者其他基站发送。
在现有技术中， 基站通常只在信令信道上发送信令信道的指示消息， 而 当终端未成功接收该指示消息时，则陷入不明确哪个信道为信令信道的场景， 无法进行信令传输， 例如， 当信令信道发生切换时， 基站会在信令信道上发 送切换信令， 而当终端由于处于休眠期间或者因为其他原因未接收到该切换 信令， 则终端就丢失了该基站所在小区系统的信令信道， 这时终端需要尽快 找到信令信道； 又例如， 当终端刚刚进入该基站的小区系统的范围时， 也需 要尽快找到信令信道。 在现有技术中， 终端需要逐一对当前选择的信道进行 监听以判断该信道是否为信令信道。
而在本实施例的步骤 302中， 基站可以在终端当前选择的数据信道上发 送指示消息， 以使终端根据所述指示消息中包含的信令信道指示信息确定信 令信道。
具体地， 基站可以按照预设的时间周期在每个数据信道上发送包含信令 信道指示信息的指示消息， 或者， 也可以通过终端在选择的数据信道上主动 向基站发送信令信道指示请求后， 在该数据信道上对该终端进行回复， 或者， 也可以通过其他方式使得所述选择的数据信道包含所述信令信道指示。
在终端确定信令信道之后， 基站与终端之间就可以进行信令传输， 从而 使终端接入基站所在的小区系统。
本实施例， 通过基站在终端选择的数据信道上发送包含信令信道指示信
息的指示消息， 使得终端在确定出所选择的信道为数据信道后， 能够通过该 数据信道获得信令信道的信息， 从而使终端避免了扫描多个数据信道直到确 定出信令信道的过程， 从而能够减少确定信令信道， 并接入通信系统所需的 时间， 提高效率。
上述实施例， 在一种可行的实现方式中， 步骤 302可以为： 基站可以在 部分或者全部数据信道上下发包含信令信道指示信息的指示消息。
进一步具体地， 上述步骤可以为： 基站按照预设的时间周期， 在每个所 述数据信道上广播包含信令信道指示信息的指示消息。
相应地， 终端可以在该小区系统的任意一个数据信道上接收基站广播的 指示消息。 这样， 终端只要确定出所选择的信道为数据信道， 即可在该数据 信道读取基站广播的指示消息中的信令信道指示信息， 从而确定信令信道。
图 4为本发明信令信道位置确定方法实施例五的流程图， 本实施例的执 行主体为基站， 本实施例在图 3所示实施例的基础上， 增加了基站与终端在 任意一个数据信道上进行交互， 发送包含信令信道指示的指示消息的过程。 如图 4所示， 本实施例的方法可以包括：
步骤 401、 基站设置指示消息， 所述指示消息中包括信令信道指示信息。 步骤 402、 基站接收终端在所选择的任意一个数据信道上发送的信令信 道指示请求。
其中，步骤 401和步骤 402没有严格的顺序，步骤 401只需在步骤 403 之前完成即可。
具体地， 所述信令信道指示请求可以为终端可以在所述选择的数据信 道上向基站发送一个信令信道指示的请求帧。
步骤 403、 基站根据所述信令信道指示请求， 在所述数据信道上发送所 述指示消息， 以使终端根据所述指示消息中的信令信道指示信息确定信令信 道的位置。
基站可以只在收到信令信道指示请求之后， 在同一数据信道进行回复， 这样， 基站可以有针对性地发送所述信令信道指示信息， 使终端快速地确定 信令信道。
步骤 403可以采用单播的方式， 在同一数据信道对终端进行回复， 也可 以采用广播的方式在所有工作信道上发送所述指示消息。
之后， 基站可以在所述信令信道上向终端发送信令或接收终端发送的信 本实施例， 基站可以根据终端在任意一个数据信道上发送的信令信道指 示请求进行回复， 并在回复的指示消息中携带信令信道指示信息， 以使终端 确定信令信道， 从而使终端避免了扫描多个数据信道直到确定出信令信道的 过程， 从而能够减少确定信令信道， 并接入通信系统所需的时间， 提高效率。
图 5为本发明信令信道位置确定方法实施例六的信令流程图， 图 5显示 了终端与基站进行交互的过程， 如图 5所示， 本实施例的步骤可以包括： 步骤 501、 终端在至少一个信道中选择一个数据信道。
步骤 502、终端在所述选择的数据信道上向基站发送信令信道指示请求。 步骤 503、 基站根据所述信令信道指示请求， 在所述终端选择的数据信 道上发送包含信令信道指示信息的指示消息。
步骤 504、 终端在所述选择的数据信道上读取信令信道指示信息。
步骤 505、 终端根据所述信令信道指示信息确定信令信道的位置。
本实施例， 终端可以在任何一个数据信道上向基站发送信令信道指示请 求， 并根据基站的回复信令信道指示信息确定信令信道， 从而避免了扫描多 个数据信道直到确定出信令信道的过程， 从而能够减少确定信令信道， 并接 入通信系统所需的时间， 提高效率。
其中， 在另一种可行的实施方案中， 步骤 502和步骤 503也可以采用以 下步骤代替： 基站按照预设的时间周期， 在每个所述数据信道上广播包含信 令信道指示信息的指示消息。 其他步骤可以与上述实施例相同。 而且该替代 步骤与步骤 501没有顺序关系。
在该实施方案中， 由于在每个数据信道上都包含信令信道指示信息， 因 此， 终端可以在选择的任意一个数据信道上获取到信令信道指示信息， 以确 定信令信道。
