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, 所描述的实施例仅仅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。

本发明实施例一
提供一种通话方法, 可以应用于如图 1所示的通话系统中,在如图 1所示的 通话系统中包括: 第一通话方, 及与第一通话方之间连接的第二通话方, 即通 话双方之间通过直通模式连接。其中, 第一通话方和第二通话方是指可以进行 语音通信的终端设备, 比如对讲机或可以实现无线通话的终端比如手机等。
本发明实施例的通话方法流程图如图 2所示, 包括:
步骤 101, 当第一通话方检测到第一通话方停止输入语音数据时, 发送呼 叫保持请求, 比如控制信令块保持( Control Signalling BlocK, CSBK-remain, 简称 C-R )请求。
可以理解,本实施例中第一通话方与第二通话方之间的通信可以釆用双时 隙 (具体为第一时隙和第二时隙) 的通信技术, 比如釆用时分多址 (Time Division Multiple Access, TDMA )通信技术, 在本实施例的通话方法中只会在 其中一个时隙(比如第一时隙)中进行通话, 而第一通话方和第二通话方可以 在另一个时隙中传输数据或其它业务。
具体地, 本实施例中, 在呼叫建立后, 对于其中一个通话方(比如第一通 话方)可以将麦克风和喇叭开启, 当第一通话方处于发射语音数据的状态时, 从麦克风输入语音数据, 并由第一通话方所包括的发射模块进行发射, 这时喇 叭不输出数据, 当第一通话方检测到麦克风停止输入语音数据,说明用户停止 说话, 则该第一通话方会通过发射模块在第一时隙发送呼叫保持请求, 用来保 持第一通话方和第二通话方之间已建立的呼叫。为了避免两个通话方的用户同 时说话造成的冲突, 可以执行下述步骤 102和 103。
进一步地,如果第一通话方处于接收语音数据时,不使用麦克风输入数据, 一旦喇八停止语音数据输出,则该第一通话方对麦克风是否输入语音数据进行 检测, 如果检测到语音数据, 则可以开启发射模块。
步骤 102, 第一通话方在第一时隙的第一部分帧中发起第一语音数据的发 射。 步骤 103, 当第二通话方接收到上述呼叫保持请求, 在第一时隙的第二部 分帧中发起第二语音数据的发射。
上述第一语音数据和第二语音数据分别指第一通话方和第二通话方发射 的语音数据; 上述第一部分帧和第二部分帧是指第一时隙上的不同帧, 比如第 一部分帧为奇数 ( Odd number )帧, 第二部分帧为偶数 ( even number )帧等; 且上述发起某一语音数据的发射是指通过通话方的麦克风输入语音数据,并通 过通话方所包括的发射模块发射该语音数据。
进一步地, 如果在某一通话方(比如第一通话方)发起语音数据的发射对 应帧(即第一部分帧)之前, 该第一通话方的用户已经开始说话, 则第一通话 方会将麦克风接收的用户输入语音数据先緩存起来; 并在第一部分帧打来, 当 该第一通话方发起第一语音数据的发射时,第一通话方会将该第一语音数据中 非语音(no-vad )部分去掉, 并发射去掉非语音部分的第一语音数据, 且在空 下来的帧中发射该用户输入语音数据。其中第一通话方去掉的非语音部分所占 用帧的长度, 可以与上述緩存的用户输入语音数据所占用帧的长度一致, 比如 都是 60ms。 其中用户在说话时, 每个字与每个字之间会有一定的间隙, 即没 有语音的部分, 则第一通话方将上述第一语音数据中该部分(非语音部分)去 掉, 就能发射緩存的用户输入语音数据了, 相当于将用户的语音加快, 比如加 快 120ms, 而人耳一般不会察觉这种变化, 因此当发送到第二通话方时, 用户 体验不会产太大的变化, 同时也不会丟弃用户输入的语音。
例如图 3所示, 移动台 ( Moble Station, MS ) A和移动台 B之间进行通话, 当 MS A的用户停止说话, MS A会在 F帧里打包结束信息并发送 C-R请求(图 3 中所示), 则该 MS A可以在之后的偶数帧(E帧)发起语音数据的发射; 当 MS B在接收到上述 C-R请求后, 在奇数帧(0帧)发起语音数据的发射。 同样, 当 MS B在停止输入语音数据并发送了 C-R请求后,可以在偶数帧继续发起语音数 据的发射, 依次类推。
其中, 当用户停止说话时,移动台可以还可以在检测到该移动台包括的麦 克风停止输入语音数据的一帧打包结束信息; 且图 3中 A到 F为一个超帧, 表示 该移动台正在发射语音数据, 而对端通话方正接收该语音数据。
可见,在通话双方是直通的模式下, 当第一通话方和第二通话方通过第一 时隙进行通话的过程中, 当第一通话方在检测到停止数据语音数据时,发送呼 叫保持请求来保持通话双方的呼叫,并在第一时隙的第一部分帧中发起语音数 据的发射,而第二通话方是在接收到呼叫保持请求后的第二部分帧中发起语音 数据的发射。这样当某一通话方在停止发射语音数据时, 可以通过发送呼叫保 持请求来保持呼叫, 而不需要某一通话方的用户操作按键来重新建立呼叫连 接, 对于用户来说是透明的, 这样可以简化通话过程中用户操作, 且由于不需 要多次重复建立呼叫, 使得通话过程更为连续。
另外, 两个通话方在进行通话时只使用一个时隙即第一时隙,相对于现有 技术中在一个时隙中发射数据,在另一个时隙中接收数据,可以减少资源消耗。
进一步地, 本实施例的方法中, 在通过呼叫保持请求保持呼叫连接后, 通 话双方是在第一时隙的不同帧内发起语音数据的发射,可以避免通话双方的用 户同时说话造成同时发射语音数据的冲突。
需要说明的是, 上述步骤 101到 103说明的是, 当第一通话方与第二通话方 在建立呼叫之后的通话, 而在上述步骤 101之前, 第一通话方还可以通如下的 步骤 104和 105实现呼叫的建立; 且在上述步骤 105之后通过步骤 106, 可以实现 另一种情况下的呼叫保持。 流程图如图 4所示, 包括:
步骤 104, 第一通话方在第一时隙内发送呼叫建立请求, 比如控制信令块 建立 (CSBK-setup, C-S )请求给第二通话方, 当第二通话方接收到该呼叫建 立请求后,第二通话方的用户可以摘机,则第二通话方就会返回呼叫应答(call answer )。
步骤 105, 当第一通话方接收到第二通话方发送的呼叫应答, 在第一时隙 发射第一语音数据。
当第一通话方和第二通话方在建立呼叫后,通话双方可以在第一时隙进行 语音数据的传输, 其中一个通话方在发射语音数据时, 另一通话方只能处于接 收状态, 在这个过程中, 如果通话方在发射语音数据时, 只会开启发射模块而 不会开启接收模块,如果通话方在接收语音数据时, 只开启接收模块而不会开 启发射模块; 且其中任一通话方只有在有语音数据输入到麦克风时, 该通话方 才会开启发射模块以发射语音数据, 否则发射模块会处于关闭状态。这样可以 减少通话方的资源消耗。 步骤 106, 如果第一通话方在预置的时间内未发射第一语音数据, 且未接 收第二通话方发射的第二语音数据,第一通话方发送呼叫保持请求给第二通话 方。
如果在第一通话方和第二通话方建立呼叫后,如果任一通话方都没有发射 语音数据,为了保持该建立的呼叫,需要通话方发送呼叫保持请求。进一步地, 如果任一通话方(比如第一通话方)连续 N次(比如两次)未接收到第二通话 方发送的呼叫保持请求,且第一通话方在预置的时间未接收到第二通话方发射 的第二语音数据, 则第一通话方发送呼叫结束请求, 比如控制信令块结束 ( CSBK-Drop, C-D )请求, 来结束该呼叫连接。
且需要说明的是, 上述步骤 101到 103, 与步骤 106之间没有绝对的顺序关 系, 可以同时执行, 也可以顺序执行, 图 4中所示的只是其中一种具体的实现 方法。
例如图 5a所示, MS A会在第一时隙发送 C-S请求给 MS B, 该 MS B会自动 回复确认收到该 C-S请求的确认信息( ACK ),然后双方移动台会响铃; 当 MS B 的用户摘机后, 会返回呼叫应答给 MS A; 当 MS A接收到该呼叫应答, 就会发 射语音数据, 即在第一时隙的 A到 F帧中发射语音数据。 其中, 如果系统对呼 叫建立的握手时间要求更高, 则上述 MS B可以不需要回复 ACK, 直接响铃。
例如图 5b所示, 在 MS A和 MS B建立呼叫后, 当 MS A停止发射语音数据, 并发送了 C-R请求后, 如果在两个超帧( A到 F为一个超帧)内都没有语音数据 发射, 且没有接收 MS B的语音数据, 则会再次发送 C-R请求来保持呼叫连接。 本发明实施例二
提供一种通话方法, 主要可以应用于如图 6所示的通话系统中, 在如图 6 所示的通话系统中包括: 第一通话方、 中转台和第二通话方, 第一通话方通过 中转台与第二通话方连接, 即通话双方之间通过中转模式连接。 其中, 中转台 可以是指基站或中继器等可以实现中转的设备。
本实施例的通话方法是如图 6所示的通话系统中, 由任一通话方比如第一 通话方所执行的方法, 流程图如图 7所示, 包括:
步骤 201, 当第一通话方检测到第一通话方停止输入语音数据时, 发送呼 叫保持请求比如 C-R请求。 可以理解,本实施例中第一通话方与第二通话方之间的通信可以釆用双时 隙的通信技术,在本实施例的通话方法中只会在其中一个时隙(比如第一时隙) 中进行通话,而第一通话方和第二通话方可以在另一个时隙中传输数据或其它 业务。
具体地, 本实施例中, 在呼叫建立后, 对于其中一个通话方(比如第一通 话方)处于发射语音数据的状态时, 从麦克风输入语音数据, 并由第一通话方 所包括的发射模块进行发射, 这时喇八不输出数据,且发射的语音数据是通过 中转台再发送给第二通话方。 当第一通话方检测到麦克风停止输入语音数据, 说明用户停止说话,则该第一通话方会通过发射模块在第一时隙发送呼叫保持 请求, 用来保持第一通话方和第二通话方之间已建立的呼叫, 该呼叫保持请求 会先发送到中转台, 然后中转台再发送给第二通话方。
步骤 202, 第一通话方发送通话请求(req ), 以便于当中转台检测到第一 通话方发出通话清求, 向该第一通话方回应该通话清求, 具体地, 中转台向第 一通话方回复通话口向应 ( rsp
步骤 203, 第一通话方接收到中转台对通话请求的回应, 发起第一语音数 据的发射。
具体地, 当第一通话方在发送了呼叫保持请求后, 则第一通话方和第二通 话方都可以发射语音数据, 为了避免两个通话方的用户同时说话造成的冲突, 当中转台在接收到呼叫保持请求后, 首次接到哪个通话方发射的语音数据, 则 相当于该通话方发送了通话请求,会判定允许该通话方发起语音数据, 而另一 通话方自动进入接收状态以接收语音数据;如果中转台同时接收到通话双方发 射的语音数据, 则判定允许信号强度较强的一个通话方发起语音数据的发射。
进一步地, 如果在某一通话方(比如第一通话方)发起语音数据的发射对 应帧之前, 该第一通话方的用户已经开始说话, 则第一通话方会将麦克风接收 的用户输入语音数据先緩存起来;并在中转台允许该第一通话方发起第一语音 数据的发射时,第一通话方会将该第一语音数据中非语音( no-vad )部分去掉, 并发射该去掉非语音部分的第一语音数据,且在空下来的帧中发射上述緩存的 用户输入语音数据。且其中, 第一通话方在第一语音数据中去掉的非语音部分 所占用帧的长度, 与上述用户输入语音数据所占用帧的长度一致。 可见,在通话双方是中转的模式下, 当第一通话方和第二通话方通过第一 时隙进行通话的过程中, 当第一通话方在检测到停止数据语音数据时,发送呼 叫保持请求来保持通话双方的呼叫, 当中转台接收到该呼叫保持请求后,如果 检测到某一通话方发出通话请求, 则中转台向该通话方回应该通话请求, 这样 该通话方就可以发起语音数据的发射。这样当某一通话方在停止发射语音数据 时, 可以通过发送呼叫保持请求来保持呼叫, 而不需要某一通话方的用户操作 按键来重新建立呼叫连接,对于用户来说是透明的, 这样可以简化通话过程中 用户操作, 且由于不需要多次重复建立呼叫, 使得通话过程更为连续。
另外, 两个通话方在进行通话时只使用一个时隙即第一时隙,相对于现有 技术中在一个时隙中发射数据,在另一个时隙中接收数据,可以减少资源消耗。
进一步地, 本实施例的方法中, 在通过呼叫保持请求保持呼叫连接后, 可 以由中转台判定由哪一个通话方发起语音数据的发射,可以避免通话双方的用 户同时说话造成同时发射语音数据的冲突。
需要说明的是, 上述步骤 201到 203说明的是, 当第一通话方与第二通话方 在建立呼叫之后的通话, 而在上述步骤 201之前, 第一通话方还可以通如下的 步骤 204和 205实现与第二通话方的呼叫建立; 且在上述步骤 205之后第一通话 方可以通过步骤 206, 实现另一种情况下的呼叫保持。流程图如图 8所示, 包括: 步骤 204, 第一通话方在第一时隙内发送呼叫建立请求给第二通话方, 具 体地, 第一通话方发送的呼叫建立请求先发送到中转台, 然后由中转台发送给 第二通话方。 当第二通话方接收到该呼叫建立请求后, 第二通话方的用户可以 摘机, 则第二通话方就会返回呼叫应答。
步骤 205, 当第一通话方接收到第二通话方发送的呼叫应答, 在第一时隙 发射第一语音数据。
步骤 206, 如果第一通话方在预置的时间内未发射第一语音数据, 且未接 收第二通话方发射的第二语音数据,第一通话方发送呼叫保持请求给第二通话 方。
如果在第一通话方和第二通话方建立呼叫后,如果任一通话方都没有发射 语音数据,为了保持该建立的呼叫,需要通话方发送呼叫保持请求。进一步地, 如果任一通话方(比如第一通话方)连续 N次未接收到所述第二通话方发送的 呼叫保持请求, 则第一通话方发送呼叫结束请求。
且需要说明的是, 上述步骤 201到 203, 与步骤 206之间没有绝对的顺序关 系, 可以同时执行, 也可以顺序执行, 图 8中所示的只是其中一种具体的实现 方法。 本发明实施例三
提供一种通话方法, 主要可以应用于如图 6所示的通话系统中, 当第一通 话方通过中转台与第二通话方在双时隙中一个时隙(比如第一时隙)进行通话 时, 第一通话方与第二通话方之间的中转台所执行的方法, 与上述实施例二中 的通话方法相对应, 流程图如图 9所示, 包括:
步骤 301, 中转台将第一通话方在第一时隙发送的呼叫保持请求比如 C-R 请求转发给第二通话方。
本实施例中, 在呼叫建立后, 对于其中一个通话方(比如第一通话方)在 发射语音数据时, 该语音数据可以通过中转台发送给第二通话方; 当第一通话 方检测到麦克风停止输入语音数据,说明用户停止说话, 则该第一通话方会通 过发射模块在第一时隙发送呼叫保持请求,用来保持第一通话方和第二通话方 之间已建立的呼叫, 该呼叫保持请求会先发送到中转台, 然后中转台再发送给 第二通话方。
为了避免两个通话方的用户同时说话造成的冲突,中转台可以执行下述步 骤 302或 303。
步骤 302, 中转台如果检测到第一通话方发出通话请求, 向第一通话方回 应通话请求, 以使得第一通话方发起第一语音数据的发射。
步骤 303, 中转台如果检测到第二通话方发出通话请求(req ), 向第二通 话方回应通话请求, 以使得第二通话方发起第二语音数据的发射, 具体地, 中 转台向第二通话方回复通话响应 (rsp )。
具体地, 当第一通话方将呼叫保持请求通过中转台发送给第二通话方后, 则第一通话方和第二通话方都可以发射语音数据,当中转台首次接到哪个通话 方发射的语音数据, 则相当于检测到该通话方发送的通话请求,会判定允许该 通话方发起语音数据, 而另一通话方自动进入接收状态以接收语音数据; 如果 中转台同时接收到通话双方发射的语音数据,则判定允许信号强度较强的一个 通话方发起语音数据的发射。
可见,在通话双方是中转的模式下, 当第一通话方和第二通话方通过第一 时隙进行通话的过程中, 当第一通话方在检测到停止数据语音数据时,发送呼 叫保持请求来保持通话双方的呼叫, 当中转台接收到该呼叫保持请求后,如果 检测到某一通话方发出通话请求, 则中转台向该通话方回应该通话请求, 这样 该通话方就可以发起语音数据的发射。这样当某一通话方在停止发射语音数据 时, 可以通过发送呼叫保持请求来保持呼叫, 而不需要某一通话方的用户操作 按键来重新建立呼叫连接,对于用户来说是透明的, 这样可以简化通话过程中 用户操作, 且由于不需要多次重复建立呼叫, 使得通话过程更为连续。
另外, 两个通话方在进行通话时只使用一个时隙即第一时隙,相对于现有 技术中在一个时隙中发射数据,在另一个时隙中接收数据,可以减少资源消耗。
进一步地, 本实施例的方法中, 在通过呼叫保持请求保持呼叫连接后, 可 以由中转台判定由哪一个通话方发起语音数据的发射,可以避免通话双方的用 户同时说话造成同时发射语音数据的冲突。
进一步地, 上述步骤 301到 303是在中转的模式下, 中转台在第一通话方和 第二通话方进行通话时, 保持呼叫的方法。 在一个具体的实施例中, 当任一通 话方比如第一通话方连续 N次未接收到第二通话方发送的呼叫保持请求, 且在 预置的时间未接收到第二通话方发射的第二语音数据时,该第一通话方可以发 送呼叫结束请求; 当本实施例的中转台接收到第一通话方发送的呼叫结束请 求, 向第二通话方发送至少一次呼叫结束请求, 以结束呼叫。
例如图 10a所示, MS A和 MS B之间进行通话, 当 MS A的用户停止说话, MS A会通过中转台发送 C-R请求, 则 MS A和 MS B可以在之后的帧中发射语音 数据。 在这个过程中, 为了避免通话双方同时发射语音数据造成的冲突, 当中 转台在接收到 MS A发送的 C-R请求后,就会决定哪个移动台可以发起语音数据 的发射。
本实施例中,是 MS B在接收到上述 C-R请求后, 首次发射语音数据以进行 通话请求, 则中转台在接收到该通话请求后, 会向 MS B返回通话响应, 这样 MS B就会发起语音数据的发射。 图 10a中 A到 F为一个超帧,表示该移动台正在 发射语音数据, 而对端通话方正接收该语音数据。 例如图 10b所示, MS A会在第一时隙通过中转台发送 C-S请求给 MS B , 该 MS B会自动回复确认收到该 C-S请求的确认信息, 然后双方移动台会响铃; 当 MS B的用户摘机后,会通过中转台返回呼叫应答给 MS A; 当 MS A接收到该呼 叫应答, 就会发射语音数据, 即在第一时隙的 A到 F帧中发射语音数据。
例如图 10c所示,在 MS A和 MS B建立呼叫后, 当 MS A停止发射语音数据, 如果 MS A的用户挂机, 则 MS A会发送呼叫结束请求即 C-D请求, 而中转台可 以发送至少一次呼叫结束请求给 MS B来结束该呼叫; 或者当 MS A连续几次都 未接收到 MS B发送的呼叫保持请求和语音数据, 也没有语音数据需要发送, 则 MS A也会发送上述 C-D请求。
可见, 上述实施例二和实施例三说明了在中转的模式下,通话双方进行通 话的方法,在其它情况下,比如在集群的环境下,也可以适用于上述通话方法, 具体通话方法与上述实施例二和实施例三中所述的方法类似。具体地,在集群 的模式下, 集群系统充当中转台的作用, 则在呼叫保持时, 由中转台来判定由 集群中哪个通话方来先发起语音数据的发射。 本发明实施例还提供一种通话终端, 即上述的第一通话方, 主要用于与第 二通话方在第一时隙进行通话,且该通话终端与第二通话方可以按照上述实施 例一的方法进行通话, 结构示意图如图 11所示, 包括:
保持发送单元 10, 用于当检测到所述通话终端停止输入语音数据时,发送 呼叫保持请求,以使得所述第二通话方在接收到所述保持发送单元 10发送的呼 叫保持请求, 在所述第一时隙的第二部分帧中发起第二语音数据的发射;
语音发射单元 11,用于如果所述通话终端和第二通话方之间通过直通模式 连接,在所述保持发射单元 10发送了呼叫保持请求后,在所述第一时隙的第一 部分帧中发起语音数据的发射。
可以理解, 在通话终端中还需要包括语音接收单元(图 11中未示出), 用 来接收其它通话终端发射的语音数据,当上述语音发射单元 11在发射第一语音 数据时, 该语音接收单元关闭, 以节省资源消耗; 且当该语音接收单元在接收 对端的语音数据时, 上述语音发射单元 11关闭。
可见,在本实施例的通话终端中, 当保持发送单元 10在检测到停止数据语 音数据时, 发送呼叫保持请求来保持通话双方的呼叫, 并由语音发射单元 11 在第一时隙的第一部分帧中发起语音数据的发射,而第二通话方是在接收到呼 叫保持请求后的第二部分帧中发起语音数据的发射。这样当某一通话方在停止 发射语音数据时, 可以通过发送呼叫保持请求来保持呼叫, 而不需要某一通话 方的用户操作按键来重新建立呼叫连接,对于用户来说是透明的, 这样可以简 化通话过程中用户操作,且由于不需要多次重复建立呼叫,使得通话过程更为 连续。 另外, 两个通话方在进行通话时只使用一个时隙即第一时隙, 相对于现 有技术中在一个时隙中发射数据,在另一个时隙中接收数据, 可以减少资源消 耗。 进一步地, 在通过呼叫保持请求保持呼叫连接后, 该通话终端中的语音发 射单元 11是在第一时隙内,且与第二通话方发起语音数据的不同帧内发起第一 语音数据的发射,可以避免通话双方的用户同时说话造成同时发射语音数据的 冲突。
参考图 12所示, 在一个具体的实施例中, 该通话终端除了可以包括如图 11 所示的结构外, 还可以包括通话请求单元 12、 储存单元 13、 呼叫建立单元 14 和呼叫结束单元 15, 其中:
通话请求单元 12, 用于发送通话请求, 以使得所述通话终端与第二通话方 之间的中转台在接收到所述保持发送单元 10发送的呼叫保持请求后,如果检测 应所述通话请求。且该通话请求单元 12还可以在接收到第二通话方发送的呼叫 保持请求后, 发送通话请求。
储存单元 13,用于储存在发起所述第一语音数据的发射之前的用户输入语 音数据。
呼叫建立单元 14,用于在所述第一时隙发送呼叫建立请求给所述第二通话 方。
呼叫结束单元 15, 用于如果所述连续 N次未接收到所述第二通话方发送的 呼叫保持请求, 且在预置的时间未接收所述第二通话方发射的第二语音数据, 则发送呼叫结束请求。
在本实施例的通话终端中, 在语音发射单元 11发起第一语音数据之前, 如 果用户已经输入部分语音数据,则可以先通过上述储存单元 13緩存该用户输入 语音数据, 则当所述语音发射单元 11发起所述第一语音数据的发射时, 可以将 第一语音数据中非语音部分去掉,并发射所述储存单元 13緩存的用户输入语音 数据, 和发射去掉非语音部分的第一语音数据, 这样可以不用丟弃用户输入的 语音。且本实施例的通话终端在建立呼叫时, 可以通过呼叫建立单元 14发送呼 叫建立请求, 当接收到所述第二通话方发送的呼叫应答时, 上述语音发射单元 11会在所述第一时隙发射第一语音数据。
进一步地,上述保持发送单元 10还用于如果所述语音发射单元 11在预置的 时间内未发射第一语音数据,且通话终端中包括的语音接收单元未接收所述第 二通话方发射的第二语音数据,发送呼叫保持请求给所述第二通话方。 而如果 连续 N次未接收到所述第二通话方发送的呼叫保持请求, 则呼叫结束单元 15发 送呼叫结束请求, 以结束该呼叫; 或如果该通话终端的用户挂机, 则该呼叫结 束单元 15也会发送呼叫结束请求来结束该呼叫。
另一方面,如果该通话终端与第二通话方之间是中转连接的模式, 则上述 通话请求单元 12会在保持发送单元 10发送了呼叫保持请求后, 发送通话请求, 以要求中转台判定该通话终端发起第一语音数据的发射;在接收到中转台发送 的对所述通话请求的回应, 上述语音发射单元 11会发起第一语音数据的发射。 这样在通过呼叫保持请求保持呼叫连接后,可以由中转台判定由哪一个通话方 发起语音数据的发射,可以避免通话双方的用户同时说话造成同时发射语音数 据的冲突。 本发明实施例还提供另一种通话终端, 即上述的第一通话方, 主要用于通 过中转台与第二通话方在第一时隙进行通话,且该通话终端与第二通话方可以 按照上述实施例二的方法进行通话, 结构示意图如图 13所示, 包括:
呼叫保持单元 20, 用于当检测到所述通话终端停止输入语音数据时,发送 呼叫保持请求;
通话请求单元 21, 用于在呼叫保持单元 20发送了呼叫保持请求后,发送通 话请求, 以便于当所述中转台检测到所述通话终端发出通话请求, 向所述通话 终端回应所述通话请求;
语音发起单元 22,用于接收到所述中转台对所述通话请求单元 21发送的通 话请求的回应, 发起第一语音数据的发射。
可以理解, 在通话终端中还需要包括语音接收单元(图 13中未示出), 用 来接收其它通话终端发射的语音数据,当上述语音发起单元 22在发射第一语音 数据时, 该语音接收单元关闭, 以节省资源消耗; 且当该语音接收单元在接收 对端的语音数据时, 上述语音发起单元 22关闭。
本发明实施例的通话终端通过中转台与第二通话方在第一时隙进行通话 时, 当呼叫保持单元 20在检测到停止数据语音数据时,发送呼叫保持请求来保 持通话双方的呼叫, 当中转台接收到该呼叫保持请求后,如果检测到通话终端 中的通话请求单元 21发出通话请求, 则中转台向该通话终端回应该通话请求, 这样当通话终端的语音发起单元 22就可以发起语音数据的发射。这样当通话终 端在停止发射语音数据时, 可以通过发送呼叫保持请求来保持呼叫, 而不需要 通话终端的用户操作按键来重新建立呼叫连接,对于用户来说是透明的, 这样 可以简化通话过程中用户操作,且由于不需要多次重复建立呼叫,使得通话过 程更为连续。 另外, 两个通话方在进行通话时只使用一个时隙即第一时隙, 相 对于现有技术中在一个时隙中发射数据,在另一个时隙中接收数据, 可以减少 资源消耗。 进一步地, 本实施例的方法中, 在通过呼叫保持请求保持呼叫连接 后, 可以由中转台判定由哪一个通话方发起语音数据的发射, 可以避免通话双 方的用户同时说话造成同时发射语音数据的冲突。
进一步地,在一个具体的实施例中,通话终端还可以包括语音储存单元 23 和呼叫结束单元 24 (在图 13中虚线框表示), 其中:
语音储存单元 23,用于储存在发起所述第一语音数据的发射之前的用户输 入语音数据;
呼叫结束单元 24, 用于如果所述通话终端连续 N次未接收到所述第二通话 方发送的呼叫保持请求,且在预置的时间未接收所述第二通话方发射的第二语 音数据, 则发送呼叫结束请求。
具体地,在本实施例的通话终端中,在语音发起单元 22发起第一语音数据 之前, 如果用户已经输入部分语音数据, 则可以先通过上述语音储存单元 23 緩存该用户输入语音数据,则当所述语音发起单元 22发起所述第一语音数据的 发射时, 可以将第一语音数据中非语音部分去掉, 并发射所述语音储存单元 23 緩存的用户输入语音数据和去掉非语音部分的第一语音数据,这样可以不用丟 弃用户输入的语音。进一步地, 上述呼叫保持单元 20还用于如果所述语音发起 单元 22在预置的时间内未发射第一语音数据,且通话终端中包括的语音接收单 元未接收所述第二通话方发射的第二语音数据,发送呼叫保持请求给所述第二 通话方。 而如果连续 N次未接收到所述第二通话方发送的呼叫保持请求, 且在 预置的时间内未接收到第二通话方发射的第二语音数据, 则呼叫结束单元 24 发送呼叫结束请求, 以结束该呼叫; 或如果该通话终端的用户挂机, 则该呼叫 结束单元 24也会发送呼叫结束请求来结束该呼叫。
进一步地, 本实施例的通话终端还可以包括呼叫建立单元(图 13中未示 出), 在建立呼叫时, 可以通过呼叫建立单元发送呼叫建立请求, 当接收到所 述第二通话方发送的呼叫应答时,上述语音发起单元 22会在所述第一时隙发射 第一语音数据。 本发明实施例还提供一种中转台,主要用于中转第一通话方与第二通话方 在第一时隙进行的通话, 且该中转台可以按照上述实施例三的方法进行通话, 结构示意图如图 14所示, 包括:
转发单元 30,用于将所述第一通话方发送的呼叫保持请求转发给所述第二 通话方,所述呼叫保持请求是所述第一通话方在检测到所述第一通话方停止输 入语音数据时发送的;
通话回应单元 31, 用于当转发单元 30在转发了呼叫保持请求后,如果检测 到所述第一通话方发出通话请求, 向所述第一通话方回应所述通话请求, 以使 得所述第一通话方发起第一语音数据的发射; 或, 用于如果检测到所述第二通 话方发出通话请求, 向所述第二通话方回应所述通话请求, 以使得所述第二通 话方发起第二语音数据的发射。
本发明实施例的中转台在转发第一通话方和第二通话方的通话时,当第一 通话方在检测到停止数据语音数据时,发送呼叫保持请求来保持通话双方的呼 叫, 中转台中的转发单元 30会将该呼叫保持请求转发给第二通话方,如果通话 回应单元 31检测到第一通话方发出通话请求,则向该第一通话方回应该通话请 求, 这样该第一通话方就可以发起语音数据的发射。这样当第一通话方在停止 发射语音数据时, 可以通过发送呼叫保持请求来保持呼叫, 而不需要通话方的 用户操作按键来重新建立呼叫连接,对于用户来说是透明的, 这样可以简化通 话过程中用户操作,且由于不需要多次重复建立呼叫,使得通话过程更为连续。 另外, 两个通话方在进行通话时只使用一个时隙即第一时隙,相对于现有技术 中在一个时隙中发射数据, 在另一个时隙中接收数据, 可以减少资源消耗。 进 一步地, 本实施例的方法中, 在通过呼叫保持请求保持呼叫连接后, 可以由中 转台判定由哪一个通话方发起语音数据的发射,可以避免通话双方的用户同时 说话造成同时发射语音数据的冲突。
进一步地, 在一个具体的实施例中, 中转台还可以包括结束转发单元 32 (在图 14中虚线框表示可以进一步增加的结构), 具体如果接收到所述第一通 话方发送的呼叫结束请求, 向所述第二通话方发送至少一次所述呼叫结束请 求, 以结束呼叫; 其中, 所述呼叫结束请求是所述第一通话方连续 N次未接收 到所述第二通话方发送的呼叫保持请求,且在预置的时间未接收到所述第二通 话方发射的第二语音数据时发送的。 本发明实施例还提供一种通话系统, 包括第一通话终端和第二通话终端, 其结构图与图 1中的通话系统类似, 其中, 其中第一通话终端的结构与上述图 11或 12所示的通话终端的结构类似, 不同的是, 在该第一通话终端中可以不用 包括上述通话请求单元 12。
其中, 第二通话终端, 用于在接收到所述第一通话终端发送的呼叫保持请 求, 在所述第一时隙的第二部分帧中发起第二语音数据的发射。 本发明实施例还提供一种通话系统, 包括第一通话终端, 中转台和第二通 话终端, 其结构图与图 6中的通话系统类似, 其中, 其中第一通话终端的结构 与上述图 13所示的通话终端的结构类似, 在此不进行赘述。
中转台, 用于在接收到所述第一通话终端发送的呼叫保持请求后,如果检 测到所述第一通话终端发出的通话请求,向所述第一通话终端回应所述通话请 求, 其具体结构可以与上述图 14所示的中转台的结构类似;
