图 3为本发明实施例中激活请求成功的流程图;

在实际应用中, 覆盖补偿邻区可以从节能小区发送的小区休眠请求消 息、 X2建立请求( SETUP REQUEST )、 X2建立响应( SETUP RESPONSE ) 或基站配置更新 ( ENB CONFIGURATION UPDATE ) 消息中获知节能小区 的覆盖位置信息。 所述覆盖位置信息可以包括小区的发射点经维度坐标、 覆盖半径、 扇区方向及宽度(如果为扇型小区)等能精确描述小区覆盖区 域和地理位置的信息。
节能小区可以从覆盖补偿邻区发送的小区休眠确认消息、 X2 SETUP REQUEST, X2 SETUP RESPONSE或 ENB CONFIGURATION UPDATE消 息中获知覆盖补偿邻区的覆盖补偿信息。 所述覆盖补偿信息可以是覆盖位 置信息, 表示覆盖补偿邻区当前能覆盖到的精确的覆盖区域和地理位置; 或者也可以是由百分比等形式表示的相对信息, 表示覆盖补偿邻区的覆盖 范围相对于没有提供 卜偿时的正常状态所扩大的范围。
如图 1、 图 2所示, 当节能小区需要进入休眠状态时, 向其覆盖补偿邻 区所属基站发送小区休眠请求消息。 小区休眠请求消息中可以携带节能小 区的当前覆盖位置信息。 实际上, 当节能小区需要进入休眠状态时, 可根 据已知的覆盖补偿邻区的覆盖补偿信息进行判断, 如果覆盖补偿邻区当前 已经能够覆盖到节能小区的覆盖区域, 则节能小区可以自行进入休眠状态, 无需向覆盖补偿邻区发送小区休眠请求消息; 否则, 则需要向覆盖补偿邻 区发送小区休眠请求消息。
覆盖补偿邻区所属基站收到小区休眠请求消息后, 根据该消息中携带 的节能小区的覆盖位置信息, 判断覆盖补偿邻区目前是否可以覆盖到节能 小区当前所覆盖的区域, 或覆盖补偿邻区的覆盖范围是否可以扩大到该节 能小区当前所覆盖的区域, 如果可以则回复小区休眠确认消息, 否则回复 小区休眠拒绝消息。 并且, 可以在小区休眠确认消息中携带时间信息。 并 且, 在节能小区的小区休眠请求消息得到覆盖补偿邻区的确认(即回复小 区休眠确认消息的情况) 的情况下, 覆盖补偿邻区在后续的通信过程中支 持已休眠的节能小区所在区域的通信。
节能小区收到小区休眠确认消息后, 如果小区休眠确认消息中携带有 时间信息, 则节能小区等待该时间信息所对应的时间后关闭; 否则, 节能 小区可立即关闭。
另外, 节能小区收到小区休眠拒绝消息后, 放弃休眠, 继续正常运行。 再有, 当覆盖补偿邻区负荷较高, 希望已进入休眠状态的节能小区(可 能有多个) 帮助分担负荷时, 覆盖补偿邻区可以根据保存的节能小区的覆 盖位置信息, 以及能测量到的终端位置分布信息, 判断向哪个或哪几个节 能小区所属基站发送小区激活请求消息, 以将相应节能小区激活。
为使本发明实施例的目的、 技术方案和优点更加清楚, 以下结合附图 对本发明作进一步地详细描述。
结合图 1、 图 5的实施例一描述如下:
小区 (Cell, C ) A为覆盖补偿邻区, 当前处于正常状态; Cl、 C2、 C3 为节能小区, 当前处于正常状态。
节能小区 C1当前负荷为 0,需要进入休眠状态,向覆盖补偿邻区 Cell A 所属基站发送小区休眠请求消息。 小区休眠请求消息中携带节能小区的当 前覆盖位置信息, 覆盖位置信息包括小区的发射点经维度坐标、 覆盖半径、 扇区方向及宽度(如果为扇型小区)等能精确描述小区覆盖区域和地理位 置的信息。
覆盖补偿邻区 Cell A所属基站收到小区休眠请求消息后, 根据该消息 中携带的节能小区的覆盖位置信息, 判断覆盖补偿邻区 Cell A目前不能覆 盖到节能小区 C1 当前所覆盖的区域, 但可以将覆盖范围扩大到节能小区 C1当前所覆盖的区域, 于是回复小区休眠确认消息, 在小区休眠确认消息 中携带覆盖补偿邻区扩大覆盖范围后的覆盖补偿信息 (覆盖补偿信息可以 是覆盖位置信息, 表示覆盖补偿邻区当前能覆盖到的精确的覆盖区域和地 理位置; 或者也可以是由百分比等形式表示的相对信息, 表示覆盖补偿邻 区的覆盖范围相对于没有提供补偿时的正常状态所扩大的范围), 在小区休 眠确认消息中还可携带时间信息。
覆盖补偿邻区 Cell A在回复给节能小区 C1的小区休眠确认消息中如果 携带了时间信息, 则等待该时间信息所对应的时间后将覆盖补偿邻区的覆 盖范围扩大到小区休眠确认消息中的覆盖补偿信息所指示的范围 (这里为 扩大到图 5中 50%的位置); 否则, 则可立即将覆盖补偿邻区的覆盖范围扩 大。
节能小区 C1收到小区休眠确认消息后,如果小区休眠确认消息中携带 时间信息, 则等待该时间信息所对应的时间后关闭; 否则, 可立即关闭。
覆盖补偿邻区 Cell A向其邻区 C2、 C3等发送 ENB CONFIGURATION UPDATE消息, 其中携带覆盖补偿信息, 以通知新的覆盖范围。
节能小区 C1向其邻区 Cell A、 C2、 C3等发送 ENB CONFIGURATION
UPDATE消息, 以通知节能小区 CI已进入休眠状态。
结合图 1、 图 5的实施例二描述如下:
CellA为覆盖补偿邻区, 当前处于补偿状态(这里为扩大到图 5中 50% 的位置); Cl、 C2、 C3为节能小区, C1 当前处于休眠状态, C2、 C3当前 处于正常状态。
节能小区 C2当前负荷为 0, 需要进入休眠状态, 节能小区 C2根据已 知的覆盖补偿邻区 Cell A的覆盖补偿信息判断覆盖补偿邻区当前不能覆盖 到节能小区 C2的覆盖区域。
节能小区 C2向覆盖补偿邻区 Cell A所属基站发送小区休眠请求消息。 小区休眠请求消息中携带节能小区的当前覆盖位置信息, 覆盖位置信息包 括小区的发射点经维度坐标、 覆盖半径、 扇区方向及宽度(如果为扇型小 区)等能精确描述小区覆盖区域和地理位置的信息。
覆盖补偿邻区 Cell A所属基站收到小区休眠请求消息后, 根据小区休 Θ民请求消息中携带的节能小区的覆盖位置信息, 判断覆盖补偿邻区 Cell A 目前不能覆盖到节能小区 C2当前所覆盖的区域,但覆盖补偿邻区的覆盖范 围可以扩大到节能小区 C2 当前所覆盖的区域, 于是回复小区休眠确认消 息, 在小区休眠确认消息中携带扩大覆盖范围后的覆盖补偿信息 (覆盖补 偿信息可以是覆盖位置信息, 表示覆盖补偿邻区当前能覆盖到的精确的覆 盖区域和地理位置; 或者也可以是由百分比等形式表示的相对信息, 表示 覆盖补偿邻区的覆盖范围相对于没有提供补偿时的正常状态所扩大的范 围), 在小区休眠确认消息中还可携带时间信息。
覆盖补偿邻区 Cell A在回复给节能小区 C2的小区休眠确认消息中如果 携带了时间信息, 则等待该时间信息所对应的时间后将覆盖补偿邻区的覆 盖范围扩大到小区休眠确认消息中的覆盖补偿信息所指示的范围 (这里为 扩大到图 5 中 100%的位置); 否则, 则可立即将覆盖补偿邻区的覆盖范围 扩大。
节能小区 C2收到小区休眠确认消息后,如果小区休眠确认消息中携带 时间信息, 则等待该时间信息所对应的时间后关闭; 否则, 可立即关闭。
覆盖补偿邻区 Cell A向其邻区 Cl、 C3等发送 ENB CONFIGURATION UPDATE消息, 其中携带覆盖补偿信息, 以通知新的覆盖范围。
节能小区 C2向其邻区 Cell A、 Cl、 C3等发送 ENB CONFIGURATION UPDATE消息, 以通知节能小区 C2已进入休眠状态。
结合图 1、 图 5的实施例三描述如下:
Cell A为覆盖补偿邻区,当前处于补偿状态(这里为扩大到图 5中 100% 的位置); Cl、 C2、 C3为节能小区, Cl、 C2当前处于休眠状态, C3当前 处于正常状态。
节能小区 C3当前负荷为 0, 需要进入休眠状态, 节能小区 C3根据已 知的覆盖补偿邻区 Cell A的覆盖补偿信息判断覆盖补偿邻区当前能够覆盖 到节能小区 C3的覆盖区域。
节能小区 C3 自行进入休眠状态,不向覆盖补偿邻区 CellA所属基站发 送小区休眠请求消息。
节能小区 C3向其邻区 Cell A、 Cl、 C2等发送 ENB CONFIGURATION UPDATE消息, 以通知节能小区 C3已进入休眠状态。
结合图 2、 图 5的实施例四描述如下:
CellA为覆盖补偿邻区, 当前处于补偿状态(这里为扩大到图 5中 50% 的位置); Cl、 C2、 C3为节能小区, C1 当前处于休眠状态, C2、 C3当前 处于正常状态。
节能小区 C3当前负荷为 0, 需要进入休眠状态, 节能小区 C3根据已 知的覆盖补偿邻区 Cell A的覆盖补偿信息判断覆盖补偿邻区当前不能覆盖 到节能小区 C3的覆盖区域。
节能小区 C3向覆盖补偿邻区 Cell A所属基站发送小区休眠请求消息。 小区休眠请求消息中携带节能小区的当前覆盖位置信息, 覆盖位置信息包 括小区的发射点经维度坐标、 覆盖半径、 扇区方向及宽度(如果为扇型小 区)等能精确描述小区覆盖区域和地理位置的信息。
覆盖补偿邻区 Cell A所属基站收到小区休眠请求消息后, 根据小区休
Θ民请求消息中携带的节能小区的覆盖位置信息, 判断覆盖补偿邻区 Cell A 目前不能覆盖到节能小区 C3当前所覆盖的区域,而且目前也不能再扩大覆 盖补偿邻区的覆盖范围, 于是回复小区休眠拒绝消息。
节能小区 C3收到小区休眠拒绝消息后,暂时放弃休眠,继续正常运行。 结合图 3、 图 4、 图 5的实施例五描述如下: Cell A为覆盖补偿邻区,当前处于补偿状态(这里为扩大到图 5中 100% 的位置); Cl、 C2、 C3为节能小区, 当前均处于休眠状态。
覆盖补偿邻区 Cell A负荷较高, 希望已进入休眠状态的节能小区帮助 分担负荷, 根据保存的各节能小区的覆盖位置信息, 及能测量到的终端位 置分布信息, 判断当前 C2、 C3附近的激活终端比较多。
覆盖补偿邻区 Cell A向已休眠的节能小区 C2、 C3所属基站发送小区 激活请求消息。
节能小区 C2、 C3所属基站收到小区激活请求消息后,将小区激活请求 消息中指示的节能小区激活, 如果能成功激活则回复小区激活响应消息, 否则回复小区激活失败消息。
如果覆盖补偿邻区 Cell A收到了表明节能小区 C2、 C3成功激活的小 区激活响应消息, 则可以进一步判断是否可以将自身的覆盖范围缩小 (这 里为缩小到图 5中 50%的位置), 如可以则缩小覆盖范围。
如果节能小区 C2 成功激活, 则向其邻区 Cl、 C3 等发送 ENB CONFIGURATION UPDATE消息, 以通知节能小区 C2已进入正常工作状 态; 如果节能小区 C3 成功激活, 则向其邻区 Cl、 C2 等发送 ENB CONFIGURATION UPDATE消息, 以通知节能小区 C3已进入正常工作状 态。
如果覆盖补偿邻区 CellA已将自身的覆盖范围缩小, 则向其邻区 Cl、 C2、 C3等发送 ENB CONFIGURATION UPDATE消息, 其中携带覆盖补偿 信息, 以通知新的覆盖范围。
结合以上描述可见,本发明实施例实现覆盖补偿的操作可以表示如图 6 所示的流程, 该流程包括以下步骤:
步骤 610: 当节能小区需要进入休眠状态时,根据获知的覆盖补偿邻区 的覆盖补偿信息进入休眠状态; 步骤 620:能够覆盖节能小区所覆盖区域的覆盖补偿邻区在后续的通信 过程中, 根据获知的节能小区的覆盖位置信息支持已休眠的所述节能小区 所在区域的通信。
