The above description is that the AC of the UE does not comply with the AC restriction of the eNB, and thus the S1 port handover fails. It is easy to understand that when the AC of the UE meets the AC restriction of the eNB, in step 206, the target eNB first sends a HANDOVER to the MME. REQUEST ACKNOWLEDGE, then the MME sends a HANDOVER COMMAND to the source eNB to implement the S1 port based handover. Embodiment 3: AC Acquisition Based on X2 Port Switching Process FIG. 3 shows AC acquisition processing in the X2-port based handover process according to an embodiment of the present invention. As shown in FIG. 3, the specific operation is as follows: Step 301: The UE reports a measurement report, and carries the target cell that meets the requirement in the report, for example, carries the ID of the cell. Step 302: The source eNB initiates an X2 port-based handover according to the target cell ID, and sends an X2AP message HANDOVER REQUEST to the target eNB, and carries the AC list of the UE in the request. Step 303: The target eNB according to the UE AC list transmitted from the source eNB, and the cell set The set AC limits are compared to confirm that the AC limit of the cell is not met. Step 4: 304, the target eNB sends an X2AP message HANDOVER PREPARATION FAILURE to the source eNB. The above description is that the AC of the UE does not comply with the AC restriction of the eNB, and thus the X2 port handover fails. It is easy to understand that when the AC of the UE complies with the AC restriction of the eNB, in step 304, the target eNB will send a HANDOVER to the source eNB. REQUEST ACKNOWLEDGE
(切换请求应答 ) 消息， 从而实现基于 X2口的切换。 在以上的各实施例中， eNB可以通过如下方式来确定 UE的 AC是否符 合小区的 AC限制。 方式一： 判断 UE的 AC信息是否与本地设置的允许接 入的 AC信息匹配或一致， 例如， AC信息列表中是否有与本地的 AC信息匹 配或一致 AC信息； 方式二： 判断 UE的 AC是否高于本地设置的允许接入 的 AC阈值， 例如， 如果 AC列表中有至少一个等级高于 AC阈值， 则允许 该 UE使用 eNB。 根据本发明实施例， 还提供了一种信息获取装置， 该装置可以设置于 RNC中，也可以设置于 eNB中，提供了上述信息获取装置功能的 RNC或 eNB 也在本发明的保护范围之内。 图 4是根据本发明实施例的信息获取装置的框 图。 如图 4所示， 该装置具有如下结构： 第一接口单元 2、 第二接口单元 4; 优选地， 还可以包括第一控制单元 6和第二控制单元 8。 以下具体描述上述 各组成部分的细节。 第一接口单元 2与 MME连接， 用于接收来自 MME的 UE AC信息。 该 接口单元主要用于实现接入或 S 1 口切换过程中的 UE AC信息获取。 例如， 在接入过程中， 第一接口单元 2接收 MME的上下文建立请求消 息， 并从上下文建立请求消息中获取其携带的 UE AC信息。 在 S 1切换过程 中， 第一接口单元 2接收 S 1切换请求消息， 并获取 S 1切换请求消息中携带 的 UE AC信息。 优选地， 第一控制单元 6根据第一接口单元 2获取的 UE AC信息， 判断 是否允许 UE接入或进行 S 1 口切换， 例如， 如果获取的 UE AC信息与本地 设置的允许的 UE AC信息匹配， 则允许 UE进行接入或 S 1切换。 通过上述结构，可以实现在 UE的接入或发起 S 1口切换过程中的 UE AC 信息获取， 进而可以根据获取的 UE AC信息控制 UE的接入或发起 S 1 口切 换。 第二接口单元 4与基站（ eNB )连接，用于接收来自基站的 UE AC信息。 该接口单元主要用户实现 X2 口切换过程中的 UE AC信息获取。 例如， 在 X2k口切换过程中， 第二接口单元 4接收来自基站的 X2切换请求消息， 并 获取 X2切换请求消息中携带的 UE AC信息。 优选地， 第二控制单元 8根据第二接口单元 4获取的 UE AC信息， 判断 是否允许 UE进行 X2口切换， 例如， 如果获取的 UE AC信息与本地设置的 允许的 UE AC信息匹配， 则允许 UE进行接入或 X2口切换。 通过上述结构， 可以实现在 UE发起 X2口切换过程中的 UE AC信息获 取， 进而可以根据获取的 UE AC信息控制 UE的接入或发起 X2口切换。 以上所述仅为本发明的优选实施例而已， 并不用于限制本发明， 对于本 领域的技术人员来说， 本发明可以有各种更改和变化。 凡在本发明的 ^"神和 原则之内， 所作的任何修改、 等同替换、 改进等， 均应包含在本发明的保护 范围之内。 (Switch request response) message, thereby implementing X2-port based switching.
