步骤 S401、 将要从蜂窝网络切换至 WLAN的第一移动终端接收基站发送的第一通信参 数。
步骤 S402、 在接入 WLAN中后, 使用第一通信参数在 WLAN中进行通信。
下面结合附图, 用具体实施例 1对本发明提供的该方法进行详细描述。
实施例 1 : 图 5为本发明实施例 1中提供的移动终端从蜂窝网络切换至 WLAN中, 并进行通信的流 程图, 具体包括如下处理步骤:

为描述方便且便于区分, 后续对将要从蜂窝网络切换至 WLAN的移动终端, 称作第一 移动终端,对 WLAN中的非将要从蜂窝网络切换至 WLAN的移动终端,称作第二移动终端, 如直接接入 WL AN的移动终端。
步骤 S502、基站与 WLAN中的 AP进行信息交互, 具体可以与该第一移动终端附近的指 定 AP进行信息交互。
通过与 WLAN中的指定 AP之间的信息交互, 可以获得该指定 AP确定的第二移动终端 通过该指定 AP在 WLAN中进行通信时使用的第二通信参数, 其中, 第二通信参数表征第二 移动终端在 WLAN中在确定信道空闲至进行通信之间的第二等待时长, 第二等待时长可以 包括 DIFS和 /或随机等待时长,所以,第二通信参数包括用于确定第二移动终端使用的 DIFS 的参数, 和 /或用于确定第二移动终端使用的随机等待时长的参数。
通过与 WLAN中的指定 AP之间的信息交互, 还可以获得指定 AP的当前网络盾量情况, 如负载情况、 数据包的平均时延、 拥塞情况等。
步骤 S503、 基站确定第一移动终端在 WLAN中进行通信时使用的第一通信参数, 第一 通信参数表征第一移动终端在 WLAN中, 在确定信道空闲至进行通信之间的第一等待时 长, 第一等待时长可以包括 DIFS和 /或随机等待时长, 所以, 第一通信参数包括用于确定第 一移动终端使用的 DIFS的参数, 和 /或用于确定第一移动终端使用的随机等待时长的参数。
本步骤中具体可以釆用如下方式确定第一通信参数:
第一种方式: 本方式中, 基站在确定第一通信参数之前, 不需要在上述步骤 S502中与 指定 AP之间进行通信, 具体包括如下两种情况:
第一种情况: 当在 WLAN中, 第二移动终端使用的第二等待时长是在预先设定后固定 不变时, 例如, DIFS是固定值, 确定随机等待时长的随机算法是固定的, 且随机等待时长 的取值范围是固定的, 此时, 基站可以预先获知该第二等待时长, 所以, 可以基于第二等 待时长,确定第一通信参数,且满足第一通信参数表征的第一等待时长小于第二等待时长, 例如, 第一通信参数中包括第一等待时长中 DIFS的值, 和 /或确定随机等待时长的参数, 且 使用该参数确定的随机等待时长的取值范围, 小于第二等待时长中的随机等待时长的取值 范围。 由于本步骤中第二等待时长是预先设定后固定不变的, 所以釆用该方式确定第一通 信参数时, 不需要基站在上述步骤 S502中与指定 AP之间进行通信。
第二种情况: 在 WLAN中, 第二移动终端使用的第二等待时长是由 AP根据网络情况或 终端发起业务的业务类型确定的, 并将确定的表征第二等待时长的参数告知第二移动终 端, 此时, 基站可以预先获知该第二等待时长, 所以, 可以基于第二等待时长, 确定第一 通信参数, 且满足第一通信参数表征的第一等待时长小于第二等待时长, 且第一通信参数 具体可以为基于第二等待时长确定第一等待时长的参数, 例如, 第一通信参数为第二等待 时长减去第一等待时长的差值, 从而使得第一移动终端在从基站获知该差值, 并基于从指 定 AP获知的第二等待时长, 可以确定出使用的第一等待时长。
第二种方式: 在 WLAN中, 第二移动终端使用的第二等待时长是由 AP根据网络情况或 终端发起业务的业务类型确定的, 并将确定的表征第二等待时长的参数告知第二移动终 端, 此时, 基站基于上述步骤 S502中从指定 AP获得的第二通信参数, 确定第二通信参数表 征的第二等待时长, 然后基于第二等待时长, 确定出第一通信参数, 具体可参见上述第一 种方式中的第一种情况, 在此不再详细描述。
第三种方式: 基站基于上述步骤 S502中获得的指定 AP的当前网络盾量情况, 确定第一 移动终端使用的第一通信参数, 其中, 当前网络盾量情况越差, 确定的第一通信参数表征 的第一等待时长越短;
在第三种方式中,较佳的, 当上述步骤 S502中获得的指定 AP的当前网络盾量情况相比 设定网络盾量情况差时, 取消第一移动终端通过指定 AP接入 WLAN。
第四种方式: 基站确定第一移动终端当前请求业务的盾量要求, 并基于确定的盾量要 求, 确定第一移动终端使用的第一通信参数, 其中, 盾量要求越高, 第一通信参数表征的 第一等待时长越短。
较佳的, 本实施例 1中, 对于上述四种第一通信参数的确定方式, 可以选择其中的确 定方式相结合使用, 在此不再进行详细描述。
步骤 S504、 基站在确定出第一通信参数后, 向该第一移动终端发送确定的第一通信参 数, 具体可以为向该第一移动终端发送与 WLAN中的该指定 AP对应的第一通信参数。
步骤 S505、 第一移动终端在接收基站发送的该第一通信参数后, 从蜂窝网络切换至 WLAN中, 具体可以通过该指定 AP接入 WLAN中, 具体的接入方式可釆用现有技术中的各 种方式, 在此不再进行详细描述。
步骤 S506、第一移动终端在接入 WLAN中后,使用第一通信参数在 WLAN中进行通信, 即使用第一通信参数所表征的第一等待时长在 WLAN中进行通信。 在 WLAN中进行通信的 过程中, 对于第一等待时长的使用, 可参见上述图 1和图 2所示的流程, 在此不再进行详细 描述。 具体可以为在通过该指定 AP接入 WLAN中后, 使用第一通信参数, 通过该指定 AP在 WL AN中进行通信。
釆用上述实施例 1中提供的方案, 由于第一通信参数表征的第一移动终端在 WLAN中 使用的第一等待时长, 小于第二移动终端在 WLAN中使用的第二等待时长, 所以相比第二 移动终端, 第一移动终端能够优先的占用空闲信道进行通信, 从而提高了从蜂窝网络切换 至 WLAN的移动终端在 WLAN中进行通信时的服务盾量。
基于上述图 5所示方案的描述可知, 当第一等待时长中包括 DIFS和随机等待时长时, 由于随机等待时长是釆用随机算法确定的, 虽然使用第一通信参数中确定随机等待时长的 参数所确定的随机等待时长的取值范围, 小于第二等待时长中的随机等待时长的取值范 围, 但还是有一定的概率在一次随机等待时长的确定中, 出现第一等待时长中的随机等待 时长, 不小于第二等待时长中的随机等待时长, 从而可能使得第一等待时长不小于第二等 待时长, 但是总体来讲, 由于第一等待时长中的 DIFS小于第二等待时长中的 DIFS, 第一等 待时长中的随机等待时长的取值范围, 小于第二等待时长中的随机等待时长的取值范围, 所以, 第一等待时长小于第二等待时长的概率要更高, 因此, 仍然能够提高从蜂窝网络切 换至 WLAN的移动终端在 WLAN中进行通信时的服务盾量。
并且, 当第一通信参数为第二等待时长减去第一等待时长的差值时, 则不会出现第一 等待时长不小于第二等待时长的情况。
本发明实施例还提供一种移动终端接入 WLAN的方法, 如图 6所示, 包括:
步骤 S601、 将要从蜂窝网络切换至 WLAN的第一移动终端生成身份通知消息。
步骤 S602、 在通过与 AP之间的信息交互接入 WLAN的过程中, 向该 AP发送该身份通 知消息,该身份通知消息用于告知该 AP第一移动终端为将要从蜂窝网络切换至 WLAN的终 端。

步骤 S801、 将要从蜂窝网络切换至 WLAN的第一移动终端生成身份通知消息, 该身份 通知消息中携带用于表征该第一移动终端为从蜂窝网络切换至 WLAN的移动终端的信息。
例如, 具体可以在现有的移动终端接入 AP时发送的探测请求( Probe Request )帧中添 加一个比特(bit )的信息, 或者在关联请求(Association Request )帧中添加一个 bit的信息, 使用添加有该一个 bit的信息的探测请求帧或关联请求帧, 作为身份通知消息, 添加的该一 个 bit的信息为用于表征该第一移动终端为从蜂窝网络切换至 WLAN的移动终端的信息。
步骤 S802、 在通过与 AP之间的信息交互接入 WLAN的过程中, 向该 AP发送该身份通 知消息, 该身份通知消息用于告知该 AP第一移动终端为从蜂窝网络切换至 WLAN的终端。
步骤 S803、该 AP在接收到该第一移动终端发送的身份通知消息后,基于接收的该身份 通知消息, 确定第一移动终端为从蜂窝网络切换至 WLAN的终端。

本步骤可具体执行如下:
该 AP接收其它移动终端发送的 RTS4艮文和 CTS4艮文, 并从 RTS4艮文和 CTS4艮文中获得 携带的 NAV值, 所获得的 NAV值即为其它移动终端配置的 NAV值; 在获得 NAV值后, 基于 接收到该 NAV值的时刻和 NAV值表征的时长, 对该 NAV值的有效状态进行维护, 在从接收 到该 NAV值的时刻至经过该 NAV值表征的时长内, 该 NAV值为有效的, 在从接收到该 NAV 值的时刻经过该 NAV值表征的时长后, 该 NAV值为无效的; 通过对其它移动终端配置的 NAV值的有效状态的维护, 确定当前有效的最长的 NAV值;
以当前时刻为准, 确定该最长的 NAV值表征的时长中从当前时刻起的剩余时长, 即该 NAV值表征的时长减去从接收到该 NAV值的时刻到当前时刻经过的时长;
预计该第一移动终端本次通信所需的时长, 将该时长称作预计时长, 具体可以为: 基 于该第一移动终端上 4艮的本次业务的业务类型, 确定与该业务类型对应的预计时长; 或者 基于该第一移动终端上 4艮的本次业务的待传输数据量, 确定预计时长; 或者确定预计时长 为预先设置的默认预计时长。 其中, 该第一移动终端可以在接入 WLAN的过程中向该 AP 上报本次业务的业务类型或上报本次业务的待传输数据量; 默认预计时长可以根据实际的 网络情况和当前各种业务类型的实际特性进行确定;
确定更新 NAV值为剩余时长与预计时长的和值。
步骤 S805、 向其它移动终端发送指示报文, 指示 4艮文中携带更新 NAV值。 具体可以基于现有技术中 RTS报文和 CTS报文的发送方式, 向其它移动终端发送指示 报文, 指示报文的格式可以与 RTS报文或 CTS报文的格式相同, 并在 RTS报文和 CTS报文格 式报文中用于携带 NAV值的字段携带更新 NAV值, 使得不需要对其它移动终端进行改进, 即可以能够接收并识别该指示报文。此时, 由于该指示报文也能够被该第一移动终端接收, 为了使得该第一移动终端在接收该指示 4艮文后, 不使用其中携带的更新 NAV值进行通信的 控制, 可以在该指示报文中携带无效标记信息, 例如为第一移动终端的标识信息, 使得第 一移动终端从该指示 ·ί艮文中识别出与自身对应的无效标记信息后, 即可认为该指示 4艮文中 携带的更新 NAV值对自身无效。
步骤 S806、 其它移动终端接收到该指示报文后, 从中获取携带的该更新 NAV值, 并基 于该更新 NAV值表征的时长, 对自身在 WLAN中进行通信的过程进行控制, NAV值的作用 可参见上述图 1和图 2所示流程, 在此不再进行详细描述。
釆用本发明实施例 2提供的方案, 使得其它移动终端在该更新 NAV值指示的时长内, 不试图占用 WLAN中的信道, 从而使得在该更新 NAV值指示的时长中的预留时长内, 可以 由该第一移动终端优先占用空闲信道进行通信 , 从而提高了从蜂窝网络切换至 WLAN的移 动终端在 WL AN中进行通信时的服务盾量。 基于上述图 6所示的移动终端接入 WLAN的方法, 相应的, 本发明实施例还提供一种 移动终端使用的通信参数的确定方法, 如图 9所示, 包括:
