Description

一种信道的分配、 获取方法和装置 技术领域
本发明属于通信领域, 尤其涉及一种信道的分配、 获取方法和装置。 背景技术

为了解决信道拥塞问题, 提供了固定信道分配方法和动态信道分配方法。 其中固定信道分配方法的过程简述如下:将整个服务区域分为一定数量的小区, 每个小区根据一定的信道复用形式配置一定数量的信道, 相当于在一个小区群 的不同小区间对信道完全隔离, 这种固定信道分配方法可以满足一定的信号质 量。 固定信道分配的呼叫接入控制策略为: 当有新的呼叫要求接入时, 如果相 对应的小区里存在空闲信道, 就接受一个呼叫。 这种方式不能随着业务条件和 用户分布来自动调整信道分配。 动态信道分配方法的过程简述如下: 所有的信 道资源完全共享, 当有新的呼叫接入时, 在在满足最小载波干扰比门限的信道 中按照一定的算法选择一个合适的信道为该呼叫接入服务, 这种方式虽然可以 实现信道的动态分配, 但其计算和控制复杂度高。 发明内容

为了使本发明的目的、 技术方案及优点更加清楚明白, 以下结合附图及实 施例, 对本发明进行进一步详细说明。 应当理解, 此处所描述的具体实施例仅 仅用以解释本发明, 并不用于限定本发明。
在本发明实施例中, 通过从空闲信道中选择一个作为控制信道, 用户端设 备扫描到该控制信道后, 即定位到该控制信道, 并通过该控制信道进行通信, 从而不仅可以实现信道的动态分配, 而且动态分配的计算量不大、 动态分配的 控制复杂度也较低。
为了说明本发明所述的技术方案, 下面通过具体实施例来进行说明。
图 1示出了本发明实施例提供的信道的分配方法适用的多信道共用系统的 结构, 为了便于说明, 仅示出了与本发明实施例相关的部分。
该多信道共用系统包括若干用户端设备、 若干信道和控制中心。 其中: 信道是指各用户端设备之间进行通信的信道。按照信道传输的信号的不同, 分为控制信道和数据信道。 其中控制信道一般用于传输信令, 它既可以采用专 用信道, 也可以与数据信道共用同一信道。 数据信道一般用于传输语音和数据 业务。 另外根据信道的忙闲状态, 信道可以分为空闲信道和被占用信道。
控制中心负责空闲信道的分配, 当多信道共用系统中有用户端设备需要通 信时, 该用户端设备向控制中心发出请求, 控制中心为其分配信道, 用户端设 备通过控制中心为其分配的信道进行通信。 图 2示出了本发明实施例提供的信道的分配方法的实现流程图, 该方法适 用于图 1 中的控制中心, 详述如下:
5101 , 控制中心从多信道共用系统中的空闲信道中选择至少一个空闲信道 作为控制信道。
在本实施中, 控制中心从多信道共用系统中的空闲信道中选择至少一个空 闲信道作为控制信道时, 可以随机选择, 也可以按照预设的选择规则选择, 在 此不做限定。 控制中心可以从多信道共用系统中选择一个空闲信道、 部分空闲 信道或者所有空闲信道作为控制信道。
其中判断信道是否为空闲信道的方式可以为现有技术提供的任意一种方 式, 如从所有信道中选择一个信道的干扰值最小的一个信道作为空闲信道。
5102, 向控制信道发送空闲信号, 所述空闲信号标识所述控制信道是供用 户端设备按照预设的定位方式定位到其中的控制信道。
在本实施例中, 控制中心向所有控制信道发送空闲信号, 以使用户端设备 在扫描多信道共用系统中信道时, 通过判断该信道中是否具有空闲信号来确定 该信道是否为控制信道。
其中预设的定位方式包括但不限于循环定位方式、 循环不定位方式和循环 分散定位方式。 当控制中心从多信道共用系统中选择一个空闲信道作为控制信 道时, 用户端设备采用循环定位方式定位到控制信道; 当控制中心从多信道共 用系统中选择 2个或者 2个以上空闲信道作为控制信道并向所有控制信道发送 空闲信号时, 用户端设备采用循环不定位方式或者循环分散定位方式定位到多 信道共用系统中的一个控制信道。
循环定位方式是指用户端设备按照预设的信道扫描顺序扫描多信道共用系 统中的信道, 在扫描到具有空闲信号的控制信道时, 用户端设备定位到该具有 空闲信号的控制信道。
循环不定位方式是指在不需要进行通信时, 用户端设备始终按照预设的信 道扫描顺序循环扫描多信道共用系统中的信道, 直到多信道共用系统接收到通 信请求时, 用户端设备才定位到多信道共用系统中的其中一个控制信道。
如用户端设备始终按照预设的信道扫描顺序循环扫描多信道共用系统中的 信道, 在控制中心接收到主叫请求后, 从所有控制信道中选择一个控制信道发 送保持信号时, 多信道共用系统中未在通信的用户端设备按照预设的信道扫描 顺序扫描多信道共用系统中的信道, 在扫描到具有保持信号的控制信道时, 用 户端设备锁定该具有保持信号的控制信道, 以定位到该具有保持信号的控制信 道; 在用户端设备接收到用户输入的主叫请求时, 多信道共用系统中未在通信 的用户端设备按照预设的信道扫描顺序扫描多信道共用系统中的信道, 并定位 到首次扫描到的具有空闲信号的控制信道。
循环分散定位方式是指多信道共用系统中的用户端设备按照预设的信道扫 描顺序扫描多信道共用系统中的信道, 并定位到首次扫描到的具有空闲信号的 控制信道。
在本发明其中一种实施例中, 当控制中心从多信道共用系统中选择一个空 闲信道作为控制信道时, 向该控制信道发送空闲信号, 多信道共用系统中所有 未在通信的用户端设备按照预设的信道扫描顺序扫描多信道共用系统中的信 道, 在扫描到具有空闲信号的控制信道时, 用户端设备定位到该具有空闲信号 的控制信道。 由于控制中心仅选择了一个空闲信道作为控制信道并向该控制信 道发送了空闲信号, 从而多信道共用系统中所有未在通信的用户端设备均定位 到该控制信道。
在本发明另一实施例中, 当控制中心从多信道共用系统中选择 2个或者 2 个以上空闲信道作为控制信道并向所有控制信道发送空闲信号时, 如果控制中 心接收到被叫请求, 则从所有控制信道中选择一个, 并向选择的控制信道发送 保持信号, 多信道共用系统中所有未在通信的用户端设备按照预设的信道扫描 顺序扫描多信道共用系统中的信道, 在扫描到具有保持信号的控制信道时, 用 户端设备锁定该具有保持信号的控制信道, 以定位到该具有保持信号的控制信 道, 如果用户端设备接收到用户输入的主叫请求, 多信道共用系统中所有未在 通信的用户端设备按照预设的信道扫描顺序扫描多信道共用系统中的信道, 并 定位到首次扫描到的具有空闲信号的控制信道。
在本发明另一实施例中, 当控制中心从多信道共用系统中选择 2个或者 2 个以上空闲信道作为控制信道并向所有控制信道发送空闲信号时, 多信道共用 系统中所有未在通信的用户端设备按照预设的信道扫描顺序扫描多信道共用系 统中的信道, 并定位到首次扫描到的具有空闲信号的控制信道。
S103, 在接收到通信请求时, 将用户端设备定位到的控制信道分配给该通 信请求对应的用户端设备。 其中通信请求为被叫请求或者主叫请求。
当控制中心从多信道共用系统中选择一个空闲信道作为控制信道时, 如果 通信请求为被叫请求, 则将用户端设备定位到的控制信道分配给所述通信请求 对应的用户端设备具体包括:
Al、 控制中心向控制信道发送选呼信号, 以使定位到该控制信道的用户端 设备与选呼信号进行匹配, 并在匹配成功后返回应答信号。
在本实施例中, 当控制中心接收到被叫请求时, 控制中心向控制信道发送 选呼信号, 该选呼信号中包含被呼叫用户的用户标识 (如电话号码等) 。 定位 到该控制信道的所有用户端设备通过该控制信道均能接收到该选呼信号, 各用 户端设备通过将选呼信号中包含的用户标识与本用户端设备的用户标识 (如本 用户端设备本机的电话号码) 进行匹配, 如果匹配成功, 则表示该用户端设备 的用户即为被呼叫用户, 此时, 该用户端设备通过该控制信道向控制中心返回 应答信号。 如果匹配不成功, 则表示该用户端设备的用户不是被呼叫用户, 也 就不再向控制中心返回应答信号了。
Bl、 控制中心接收用户端设备返回的应答信号, 并将该控制信道分配给返 回应答信号的用户端设备。
在本实施例中, 控制中心通过控制信道接收到用户端设备返回的应答信号 时, 将收到应答信号的控制信道分配给返回应答信号的用户端设备, 使得该用 户端设备可以通过分配的控制信道与其它用户端设备进行通信。
当控制中心从多信道共用系统中选择一个空闲信道作为控制信道时, 如果 通信请求为主叫请求, 则将用户端设备定位到的控制信道分配给所述通信请求 对应的用户端设备具体包括:
如果通信请求为定位到该控制信道的用户端设备发送的主叫请求时, 控制 中心将该控制信道分配给发送主叫请求的用户端设备。
在本实施例中, 用户端设备在接收到用户输入的主叫请求时, 通过该用户 端设备定位到的控制信道将该主叫请求发送至控制中心, 控制中心在接收到用 户端设备发送的主叫请求后, 即将该用户端设备定位到的控制信道分配给发送 主叫请求的用户端设备, 使得该用户端设备占用该控制信道与该用户端设备呼 叫的另一用户端设备进行通信。
在本发明另一实施例中,当控制中心将控制信道分配给某一用户端设备后, 控制中心重新选择一个空闲信道作为控制信道, 并向重新选定的控制信道发送 空闲信号, 其他用户端设备发现原来定位到的控制信道已被占用时, 立即重新 扫描多信道共用系统中的信道, 搜索并定位到新的具有空闲信号的控制信道。
在本发明实施例中, 由于所有的信道均可以用于控制信道和数据信道, 从 而信道的利用率高。 而且由于所有未在通信的用户端设备均定位到同一个控制 信道上, 从而无论主叫还是被叫, 都能及时的通过定位到的控制信道立即进行 通信, 使得呼叫处理的速度较快, 尤其在适用于用户数较少的有限用户的多信 道共用系统时, 呼叫处理速度更佳。
图 3是出了本发明另一实施例提供的信道的分配方法的实现流程, 详述如 下: 5201 , 控制中心从多信道共用系统中选择 2个或者 2个以上空闲信道作为 控制信道并向所有控制信道发送空闲信号。
在本实施例中, 将多信道共用系统中的 2个或者 2个以上空闲信道均作为 控制信道, 控制中心向所有控制信道发送空闲信号。 多信道共用系统中未在通 信的用户端设备始终处于循环扫描状态, 扫描多信道共用系统中具有空闲信号 的控制信道。
5202, 控制中心在接收到的通信请求为被叫请求时, 向所有控制信道中的 任意一个控制信道发送保持信号, 以使用户端设备锁定具有保持信号的控制信 道。
在本实施例中, 当控制中心接收到的通信请求为被叫请求时, 控制中心向 所有控制信道中的任意一个控制信道发送保持信号。 多信道共用系统中未在通 信的用户端设备在循环扫描信道时, 如果扫描到具有保持信号的控制信道, 则 锁定在该具有保持信号的控制信道, 保持信号保持一段时间, 直到多信道共用 系统中未在通信的用户端设备都锁定到该具有保持信号的控制信道。
5203 , 控制中心向具有保持信号的控制信道改发选呼信号, 以使锁定该具 有保持信号的控制信道的用户端设备与该选呼信号进行匹配, 并在匹配成功后 返回应答信号。
在本实施例中, 当多信道共用系统中未在通信的用户端设备都锁定到该具 有保持信号的控制信道时, 控制中心向该具有保持信号的控制信道改发选呼信 号, 由于控制中心发送保持信号和选呼信号的控制信道是同一控制信道, 即之 前锁定到该具有保持信号的控制信道的用户端设备此时锁定到该具有选呼信号 的控制信道, 所以, 锁定到该具有选呼信号的控制信道的用户端设备均可以接 收到该选呼信号, 并将选呼信号中的用户标识 (如被叫用户的电话号码) 与用 户端设备自身的用户标识 (如用户端设备本机电话号码) 进行匹配, 如果匹配 成功, 则通过该具有选呼信号的控制信道向控制中心返回应答信号, 如果匹配 不成功, 则不向控制中心返回应答信号, 同时立即释放该锁定的控制信道, 重 新进行循环扫描。
5204, 控制中心接收应答信号, 将返回应答信号的用户端设备锁定的控制 信道分配给返回应答信号的用户端设备。
在本实施例中, 控制中心在接收到用户端设备通过控制信道返回的应答信 号后, 即将该控制信道分配给该返回应答信号的用户端设备。 由于返回应答信 号的控制信道即为用户端设备之前锁定的控制信道, 因此, 也即将返回应答信 号的用户端设备锁定的控制信道分配给返回应答信号的用户端设备。 在本实施例中, 由于将所有空闲信道均作为控制信道, 从而多信道共用系 统中的用户端设备通过循环扫描的方式可以扫描到不同的控制信道, 在未接收 到被叫请求时, 多信道共用系统中的用户端设备不会定位到某一个信道, 从而 使得通信信道的选择较为灵活。
图 4是出了本发明另一实施例提供的信道的分配方法的实现流程, 详述如 下:
5301 , 控制中心从多信道共用系统中选择 2个或者 2个以上空闲信道作为 控制信道并向所有控制信道发送空闲信号。
5302, 控制中心在接收到的通信请求为主叫请求时, 将发送该主叫请求的 用户端设备扫描到的控制信道分配给发送主叫请求的用户端设备。 其中, 发送 主叫请求的用户端设备扫描到的控制信道是指用户端设备在接收到用户输入的 主叫请求后按照预设的信道扫描顺序首次扫描到的多信道共用系统中的控制信 道。
在本实施例中, 多信道共用系统中未在通信的用户端设备通过循环扫描的 方式可以扫描到多信道共用系统中具有空闲信号的控制信道, 当多信道共用系 统中未在通信的用户端设备接收到用户输入的主叫请求时, 通过循环扫描的方 式扫描到多信道共用系统中具有空闲信号的控制信道时, 定位到首次扫描到的 具有空闲信号的控制信道, 并向该首次扫描到的具有空闲信号的控制信道发送 主叫请求, 此时控制中心将该控制信道分配给发送主叫请求的用户端设备, 该 用户端设备即占用该控制信道进行通信。 其中各用户端设备对信道进行循环扫 描的顺序不同。
在本实施例中, 由于将 2个或者 2个以上空闲信道均作为控制信道, 且各 用户端设备对信道的扫描顺序不同, 而用户端设备在接收到用户输入的主叫请 求时, 即采用其扫描到的控制信道将该主叫请求发送至控制中心, 这样极大的 减少了两个用户同时发起主叫请求且同时占用同一控制信道的概率, 即本实施 例提供的方法可以有效的减少控制信道的同抢概率。
图 5是出了本发明另一实施例提供的信道的分配方法的实现流程, 详述如 下:
S401, 控制中心选择空闲信道中的 2个或者 2个以上空闲信道作为控制信 道, 向所有控制信道发送空闲信号, 以使各用户端设备分別定位到各自最先扫 描到的控制信道。
在本实施例中, 控制中心将多信道共用系统中的 2个或者 2个以上空闲信 道均作为控制信道, 并向所有控制信道发送空闲信号。 多信道共用系统中未在 通信的用户端设备扫描多信道共用系统中的所有信道, 并分別定位到最先扫描 到的控制信道上。 多信道共用系统中未在通信的用户端设备扫描多信道共用系 统中的所有信道是随机的, 这样各用户端设备定位到的控制信道也是分散的。
S402, 在接收到通信请求时, 将所述通信请求对应的用户端设备定位到的 控制信道分配给所述通信请求对应的用户端设备。 其具体过程如下:
A2、 当接收到的通信请求为被叫请求时, 控制中心向所有控制信道发送选 呼信号, 以使定位到控制信道的用户端设备与该选呼信号进行匹配, 且匹配成 功的用户端设备通过其定位到的控制信道返回应答信号。
在本实施例中, 当接收到的通信请求为被叫请求时, 控制中心向所有控制 信道发送选呼信号, 这样各用户端设备通过定位到的控制信道均可以接收到该 选呼信号, 通过将选呼信号中的用户标识 (如被叫用户电话号码) 与用户端设 备本机的用户标识 (如用户端设备本机的电话号码)进行匹配, 如果匹配成功, 则该用户端设备通过其定位到的控制信道向控制中心返回应答信号, 其他匹配 不成功的, 则不再向控制中心返回应答信号。
B2、 接收应答信号, 将返回应答信号的用户端设备定位到的控制信道分配 给返回应答信号的用户端设备。
在本实施例中, 返回应答信号的控制信道即为返回应答信号的用户端设备 定位到的控制信道, 因此, 在控制中心接收到应答信号后, 将返回应答信号的 控制信道分配给返回应答信号的用户端设备时, 即将返回应答信号的用户端设 备定位到的控制信道分配给返回应答信号的用户端设备, 用户端设备占用该控 制信道后, 即可通过该控制信道与呼叫用户进行通信。
在本发明另一实施例中, 在接收到通信请求时, 将所述通信请求对应的用 户端设备定位到的控制信道分配给所述通信请求对应的用户端设备具体包括: 当接收到的通信请求为主叫请求时, 将发送该主叫请求的用户端设备定位 到的控制信道分配给发送该主叫请求的用户端设备。
在本实施例中, 当用户端设备接收到用户输入的主叫请求时, 用户端设备 通过定位到的控制信道发送该主叫请求, 控制中心通过控制信道接收到该主叫 请求后, 将发送主叫请求的用户端设备定位到的控制信道分配给发送该主叫请 求的用户端设备。
在本发明实施例中, 在用户端设备进行通信之前, 多信道共用系统中的用 户端设备各自定位到最先扫描到的控制信道上, 这样, 在接收到主叫请求时, 可以立即采用定位到的控制信道进行通信, 在接收到被叫请求时, 控制中心在 所有控制信道上同时发送选呼信号, 各用户端设备均可以接收到该选呼信号, 从而使得被叫速度也很快, 即该方法使得呼叫处理速度快。 另外, 由于各用户 端设备分別定位到各自最先扫描到的控制信道, 使得各用户端设备定位到的控 制信道是分散的,从而极大的降低了多个用户端设备共抢同一控制信道的概率, 即降低了控制信道的同抢概率。
图 6示出了本发明实施例提供的利用信道进行通信的方法, 适用于用户端 设备, 详述如下:
S501 , 用户端设备按照预设的定位方式定位到多信道共用系统中的一个控 制信道。 其中控制信道为多信道共用系统中的具有空闲信号的空闲信道。
其中预设的定位方式包括但不限于循环定位方式、 循环不定位方式和循环 分散定位方式。

S502、 响应于通信请求, 所述用户端设备利用所述用户端设备定位到的控 制信道进行通信。
当选择空闲信道中的一个空闲信道作为控制信道并向该控制信道发送空闲 信号, 用户端设备按照循环定位方式定位到多信道共用系统中的一个控制信道 时, 用户端设备在接收到通信请求时, 用户端设备利用所述用户端设备定位到 的控制信道进行通信具体包括:

如图 13所示, 所述信道的分配系统 300包括控制设备 301、 发射器 302、 以及接收器 303。 其中, 所述控制设备 301 用于从多信道共用系统的空闲信道 中选择至少一个空闲信道作为控制信道; 所述发射器 302, 其与所述控制设备 通信连接, 用于向所述控制信道发送空闲信号, 所述空闲信号标识所述控制信 道是供用户端设备按照预设的定位方式定位到其中的控制信道; 所述接收器 303 用于接收通信请求, 在所述接收器 303接收到通信请求时, 所述控制设备 301将用户端设备定位到的控制信道分配给所述通信请求对应的用户端设备。
具体来说, 首先, 控制设备 301从多信道共用系统中的空闲信道中选择至 少一个空闲信道作为控制信道时, 可以随机选择, 也可以按照预设的选择规则 选择, 在此不做限定。 控制设备 301可以从多信道共用系统中选择一个空闲信 道、 部分空闲信道或者所有空闲信道作为控制信道。
其中判断信道是否为空闲信道的方式可以为现有技术提供的任意一种方 式, 如从所有信道中选择一个信道的干扰值最小的一个信道作为空闲信道。
接下来, 发射器 302向控制信道发送空闲信号, 所述空闲信号标识所述控 制信道是供用户端设备按照预设的定位方式定位到其中的控制信道。
在本实施例中, 发射器 302向所有控制信道发送空闲信号, 以使用户端设 备在扫描多信道共用系统中信道时, 通过判断该信道中是否具有空闲信号来确 定该信道是否为控制信道。
其中预设的定位方式包括但不限于循环定位方式、 循环不定位方式和循环 分散定位方式。 当控制设备 301从多信道共用系统中选择一个空闲信道作为控 制信道时, 用户端设备采用循环定位方式定位到控制信道; 当控制设备 301从 多信道共用系统中选择 2个或者 2个以上空闲信道作为控制信道并向所有控制 信道发送空闲信号时, 用户端设备采用循环不定位方式或者循环分散定位方式 定位到多信道共用系统中的一个控制信道。
循环定位方式是指用户端设备按照预设的信道扫描顺序扫描多信道共用系 统中的信道, 在扫描到具有空闲信号的控制信道时, 用户端设备定位到该具有 空闲信号的控制信道。
循环不定位方式是指在不需要进行通信时, 用户端设备始终按照预设的信 道扫描顺序循环扫描多信道共用系统中的信道, 直到多信道共用系统接收到通 信请求时, 用户端设备才定位到多信道共用系统中的其中一个控制信道。
如用户端设备始终按照预设的信道扫描顺序循环扫描多信道共用系统中的 信道, 在接收器 303接收到主叫请求后, 控制设备 301从所有控制信道中选择 —个控制信道, 由发射器 302发送保持信号时, 多信道共用系统中未在通信的 用户端设备按照预设的信道扫描顺序扫描多信道共用系统中的信道, 在扫描到 具有保持信号的控制信道时, 用户端设备锁定该具有保持信号的控制信道, 以 定位到该具有保持信号的控制信道; 在用户端设备接收到用户输入的主叫请求 时, 多信道共用系统中未在通信的用户端设备按照预设的信道扫描顺序扫描多 信道共用系统中的信道, 并定位到首次扫描到的具有空闲信号的控制信道。
循环分散定位方式是指多信道共用系统中的用户端设备按照预设的信道扫 描顺序扫描多信道共用系统中的信道, 并定位到首次扫描到的具有空闲信号的 控制信道。
在本发明其中一种实施例中, 当控制设备 301从多信道共用系统中选择一 个空闲信道作为控制信道时, 发射器 303向该控制信道发送空闲信号, 多信道 共用系统中所有未在通信的用户端设备按照预设的信道扫描顺序扫描多信道共 用系统中的信道, 在扫描到具有空闲信号的控制信道时, 用户端设备定位到该 具有空闲信号的控制信道。 由于控制设备 301仅选择了一个空闲信道作为控制 信道并向该控制信道发送了空闲信号, 从而多信道共用系统中所有未在通信的 用户端设备均定位到该控制信道。
在本发明另一实施例中, 当控制设备 301从多信道共用系统中选择 2个或 者 2个以上空闲信道作为控制信道, 并且发射器 302向所有控制信道发送空闲 信号时, 如果接收器 303接收到被叫请求, 则控制设备 301从所有控制信道中 选择一个, 并由发射器 302向选择的控制信道发送保持信号, 多信道共用系统 中所有未在通信的用户端设备按照预设的信道扫描顺序扫描多信道共用系统中 的信道, 在扫描到具有保持信号的控制信道时, 用户端设备锁定该具有保持信 号的控制信道, 以定位到该具有保持信号的控制信道, 如果用户端设备接收到 用户输入的主叫请求, 多信道共用系统中所有未在通信的用户端设备按照预设 的信道扫描顺序扫描多信道共用系统中的信道, 并定位到首次扫描到的具有空 闲信号的控制信道。
在本发明另一实施例中, 当控制设备 301从多信道共用系统中选择 2个或 者 2个以上空闲信道作为控制信道, 并由发射器 302向所有控制信道发送空闲 信号时, 多信道共用系统中所有未在通信的用户端设备按照预设的信道扫描顺 序扫描多信道共用系统中的信道, 并定位到首次扫描到的具有空闲信号的控制 信道。
随后, 在所述接收器 303接收到通信请求时, 所述控制设备 301将用户端 设备定位到的控制信道分配给该通信请求对应的用户端设备。 其中通信请求为 被叫请求或者主叫请求。
当控制设备 301从多信道共用系统中选择一个空闲信道作为控制信道时, 如果通信请求为被叫请求, 则控制设备 301将用户端设备定位到的控制信道分 配给所述通信请求对应的用户端设备具体包括:
发射器 302向控制信道发送选呼信号, 以利用控制设备 301使定位到该控 制信道的用户端设备与选呼信号进行匹配, 并在匹配成功后由接收器 303接收 返回的应答信号。
在本实施例中, 当接收器 303接收到被叫请求时, 控制设备 301 向控制信 道发送选呼信号, 该选呼信号中包含被呼叫用户的用户标识 (如电话号码等) 。 定位到该控制信道的所有用户端设备通过该控制信道均能接收到该选呼信号, 各用户端设备通过将选呼信号中包含的用户标识与本用户端设备的用户标识 (如本用户端设备本机的电话号码) 进行匹配, 如果匹配成功, 则表示该用户 端设备的用户即为被呼叫用户, 此时, 该用户端设备通过该控制信道向控制中 心返回应答信号。 如果匹配不成功, 则表示该用户端设备的用户不是被呼叫用 户, 也就不再向分配系统 300返回应答信号了。
接收器 303接收用户端设备返回的应答信号, 并且控制设备 301将该控制 信道分配给返回应答信号的用户端设备。
在本实施例中, 接收器 303通过控制信道接收到用户端设备返回的应答信 号时, 控制设备 301将收到应答信号的控制信道分配给返回应答信号的用户端 设备,使得该用户端设备可以通过分配的控制信道与其它用户端设备进行通信。
当控制设备 301从多信道共用系统中选择一个空闲信道作为控制信道时, 如果通信请求为主叫请求, 则控制设备 301将用户端设备定位到的控制信道分 配给所述通信请求对应的用户端设备具体包括:
如果通信请求为定位到该控制信道的用户端设备发送的主叫请求时, 控制 设备 301将该控制信道分配给发送主叫请求的用户端设备。
在本实施例中, 用户端设备在接收到用户输入的主叫请求时, 通过该用户 端设备定位到的控制信道将该主叫请求发送至控制中心, 接收器 303在接收到 用户端设备发送的主叫请求后, 控制设备 301 即将该用户端设备定位到的控制 信道分配给发送主叫请求的用户端设备, 使得该用户端设备占用该控制信道与 该用户端设备呼叫的另一用户端设备进行通信。
在本发明另一实施例中, 当控制设备 301将控制信道分配给某一用户端设 备后, 控制设备 301重新选择一个空闲信道作为控制信道, 并由发射器 302向 重新选定的控制信道发送空闲信号, 其他用户端设备发现原来定位到的控制信 道已被占用时, 立即重新扫描多信道共用系统中的信道, 搜索并定位到新的具 有空闲信号的控制信道。
在本发明实施例中, 由于所有的信道均可以用于控制信道和数据信道, 从 而信道的利用率高。 而且由于所有未在通信的用户端设备均定位到同一个控制 信道上, 从而无论主叫还是被叫, 都能及时的通过定位到的控制信道立即进行 通信, 使得呼叫处理的速度较快, 尤其在适用于用户数较少的有限用户的多信 道共用系统时, 呼叫处理速度更佳。
在本发明的一个实施例中, 控制设备 301从多信道共用系统中选择 2个或 者 2个以上空闲信道作为控制信道, 并由发射器 302向所有控制信道发送空闲 信号。
在本实施例中, 将多信道共用系统中的 2个或者 2个以上空闲信道均作为 控制信道, 发射器 302向所有控制信道发送空闲信号。 多信道共用系统中未在 通信的用户端设备始终处于循环扫描状态, 扫描多信道共用系统中具有空闲信 号的控制信道。
在接收器 303接收到的通信请求为被叫请求时, 发射器 302向所有控制信 道中的任意一个控制信道发送保持信号, 以使用户端设备锁定具有保持信号的 控制信道。
在本实施例中, 当接收器 303接收到的通信请求为被叫请求时, 发射器 302 向所有控制信道中的任意一个控制信道发送保持信号。 多信道共用系统中未在 通信的用户端设备在循环扫描信道时, 如果扫描到具有保持信号的控制信道, 则锁定在该具有保持信号的控制信道, 保持信号保持一段时间, 直到多信道共 用系统中未在通信的用户端设备都锁定到该具有保持信号的控制信道。
发射器 302向具有保持信号的控制信道改发选呼信号, 以使锁定该具有保 持信号的控制信道的用户端设备与该选呼信号进行匹配, 并在匹配成功后返回 应答信号。
在本实施例中, 当多信道共用系统中未在通信的用户端设备都锁定到该具 有保持信号的控制信道时, 发射器 302向该具有保持信号的控制信道改发选呼 信号, 由于发射器 302发送保持信号和选呼信号的控制信道是同一控制信道, 即之前锁定到该具有保持信号的控制信道的用户端设备此时锁定到该具有选呼 信号的控制信道, 所以, 锁定到该具有选呼信号的控制信道的用户端设备均可 以接收到该选呼信号, 并将选呼信号中的用户标识 (如被叫用户的电话号码) 与用户端设备自身的用户标识 (如用户端设备本机电话号码) 进行匹配, 如果 匹配成功, 则通过该具有选呼信号的控制信道向分配系统 300返回应答信号, 如果匹配不成功, 则不向分配系统 300返回应答信号, 同时立即释放该锁定的 控制信道, 重新进行循环扫描。
接收器 303接收应答信号, 控制设备 301将返回应答信号的用户端设备锁 定的控制信道分配给返回应答信号的用户端设备。
在本实施例中, 接收器 303在接收到用户端设备通过控制信道返回的应答 信号后, 控制设备 301 即将该控制信道分配给该返回应答信号的用户端设备。 由于返回应答信号的控制信道即为用户端设备之前锁定的控制信道, 因此, 控 制设备 301也即将返回应答信号的用户端设备锁定的控制信道分配给返回应答 信号的用户端设备。
在本实施例中, 由于控制设备 301将所有空闲信道均作为控制信道, 从而 多信道共用系统中的用户端设备通过循环扫描的方式可以扫描到不同的控制信 道, 在未接收到被叫请求时, 多信道共用系统中的用户端设备不会定位到某一 个信道, 从而使得通信信道的选择较为灵活。
在本发明的一个实施例中, 控制设备 301从多信道共用系统中选择 2个或 者 2个以上空闲信道作为控制信道, 并由发射器 302向所有控制信道发送空闲 信号。
在接收器 303接收到的通信请求为主叫请求时, 控制设备 301将发送该主 叫请求的用户端设备扫描到的控制信道分配给发送主叫请求的用户端设备。 其 中, 发送主叫请求的用户端设备扫描到的控制信道是指用户端设备在接收到用 户输入的主叫请求后按照预设的信道扫描顺序首次扫描到的多信道共用系统中 的控制信道。
在本实施例中, 多信道共用系统中未在通信的用户端设备通过循环扫描的 方式可以扫描到多信道共用系统中具有空闲信号的控制信道, 当多信道共用系 统中未在通信的用户端设备接收到用户输入的主叫请求时, 通过循环扫描的方 式扫描到多信道共用系统中具有空闲信号的控制信道时, 定位到首次扫描到的 具有空闲信号的控制信道, 并向该首次扫描到的具有空闲信号的控制信道发送 主叫请求,此时控制设备 301将该控制信道分配给发送主叫请求的用户端设备, 该用户端设备即占用该控制信道进行通信。 其中各用户端设备对信道进行循环 扫描的顺序不同。 在本实施例中, 由于将 2个或者 2个以上空闲信道均作为控制信道, 且各 用户端设备对信道的扫描顺序不同, 而用户端设备在接收到用户输入的主叫请 求时, 即采用其扫描到的控制信道将该主叫请求发送至分配系统 300, 这样极 大的减少了两个用户同时发起主叫请求且同时占用同一控制信道的概率, 即本 实施例提供的方法可以有效的减少控制信道的同抢概率。
在本发明的一个实施例中, 控制设备 301选择空闲信道中的 2个或者 2个 以上空闲信道作为控制信道, 发射器 302向所有控制信道发送空闲信号, 以使 各用户端设备分別定位到各自最先扫描到的控制信道。
在本实施例中, 控制设备 301将多信道共用系统中的 2个或者 2个以上空 闲信道均作为控制信道, 并由发射器 302向所有控制信道发送空闲信号。 多信 道共用系统中未在通信的用户端设备扫描多信道共用系统中的所有信道, 并分 別定位到最先扫描到的控制信道上。 多信道共用系统中未在通信的用户端设备 扫描多信道共用系统中的所有信道是随机的, 这样各用户端设备定位到的控制 信道也是分散的。
在接收器 303接收到通信请求时, 控制设备 301将所述通信请求对应的用 户端设备定位到的控制信道分配给所述通信请求对应的用户端设备。 其具体过 程如下:
当接收器 303接收到的通信请求为被叫请求时, 发射器 302向所有控制信 道发送选呼信号, 以使定位到控制信道的用户端设备与该选呼信号进行匹配, 且匹配成功的用户端设备通过其定位到的控制信道返回应答信号。
在本实施例中, 当接收器 303接收到的通信请求为被叫请求时, 发射器 302 向所有控制信道发送选呼信号, 这样各用户端设备通过定位到的控制信道均可 以接收到该选呼信号, 控制设备 301通过将选呼信号中的用户标识 (如被叫用 户电话号码) 与用户端设备本机的用户标识 (如用户端设备本机的电话号码) 进行匹配, 如果匹配成功, 则该用户端设备通过其定位到的控制信道向分配系 统 300返回应答信号, 其他匹配不成功的, 则不再向分配系统 300返回应答信 号。
接收器 303接收应答信号, 控制设备 301将返回应答信号的用户端设备定 位到的控制信道分配给返回应答信号的用户端设备。
在本实施例中, 返回应答信号的控制信道即为返回应答信号的用户端设备 定位到的控制信道, 因此, 在接收器 303接收到应答信号后, 控制设备 301将 返回应答信号的控制信道分配给返回应答信号的用户端设备时, 即将返回应答 信号的用户端设备定位到的控制信道分配给返回应答信号的用户端设备, 用户 端设备占用该控制信道后, 即可通过该控制信道与呼叫用户进行通信。
在本发明另一实施例中, 在接收器 303接收到通信请求时, 控制设备 301 将所述通信请求对应的用户端设备定位到的控制信道分配给所述通信请求对应 的用户端设备具体包括:
当接收器 303接收到的通信请求为主叫请求时, 控制设备 301将发送该主 叫请求的用户端设备定位到的控制信道分配给发送该主叫请求的用户端设备。
在本实施例中, 当用户端设备接收到用户输入的主叫请求时, 用户端设备 通过定位到的控制信道发送该主叫请求, 接收器 303通过控制信道接收到该主 叫请求后, 控制设备 301将发送主叫请求的用户端设备定位到的控制信道分配 给发送该主叫请求的用户端设备。
在本发明实施例中, 在用户端设备进行通信之前, 多信道共用系统中的用 户端设备各自定位到最先扫描到的控制信道上, 这样, 在接收到主叫请求时, 可以立即采用定位到的控制信道进行通信, 在接收到被叫请求时, 发射器 302 在所有控制信道上同时发送选呼信号,各用户端设备均可以接收到该选呼信号, 从而使得被叫速度也很快, 即该方法使得呼叫处理速度快。 另外, 由于各用户 端设备分別定位到各自最先扫描到的控制信道, 使得各用户端设备定位到的控 制信道是分散的,从而极大的降低了多个用户端设备共抢同一控制信道的概率, 即降低了控制信道的同抢概率。
本发明还提供了一种利用信道进行通信的用户端设备 400。 图 13示出了包 含本发明的实施例的信道的分配系统 300和多个用户端设备 400-1、 …、 400-m 的多信道共用系统的结构图。 以用户端设备 400-1 为例, 其可以包括: 控制器 401,用于按照预设的定位方式将用户端设备定位到多信道共用系统中的一个控 制信道, 所述控制信道为多信道共用系统中的具有空闲信号的空闲信道; 以及 收发器 402, 其与所述控制器通信连接, 用于响应于通信请求, 利用用户端设 备定位到的控制信道进行通信。

响应于通信请求, 收发器 402利用所述用户端设备 400定位到的控制信道 进行通信。

在本发明实施例中, 通过从空闲信道中选择一个作为控制信道, 用户端设 备扫描到该控制信道后, 即定位到该控制信道, 并通过该控制信道进行通信, 从而不仅可以实现信道的动态分配, 而且动态分配的计算量不大、 动态分配的 控制复杂度也较低。 另外, 通过将所有空闲信道均作为控制信道, 在接收到通 信请求时, 从控制信道中选择一个或者按照预设的信道扫描顺序扫描并定位到 某一控制信道, 从而降低了信道同抢概率。 同时通过将所有空闲信道均作为控 制信道, 用户端设备按照预设的信道扫描顺序扫描信道, 并定位到最先扫描到 的控制信道, 在接收到通信请求时, 通过定位到的控制信道进行通信, 从而不 仅降低了信道同抢概率, 同时提高了呼叫速度。
以上所述仅为本发明的较佳实施例而已, 并不用以限制本发明, 凡在本发 明的精神和原则之内所作的任何修改、 等同替换和改进等, 均应包含在本发明 的保护范围之内。
