基于切换功能的信息传递方法、 基站及终端 技术领域 本发明涉及通信领域， 具体地， 涉及基于切换功能的信息传递方法、 基 站及终端。 背景技术 在无线通信系统中， 基站与设备通过上 /下行链路进行通信， 其中， 下行 (前向） 是指基站到终端的方向， 上行（反向） 是指终端到基站的方向。 在 通常的应用中， 多个终端可同时通过上行链路向基站发送数据， 也可以同时 通过下行链路从基站接收数据。 目前， 为了提高无线覆盖质量， 通常釆用以下两种方案进行覆盖： 一种 方法是增加宏基站（ Macro BS )的数量和密度， 即， 增加宏小区（ Macro Cell ) 的数量和密度； 另一种方法是在室内安装家庭基站 （Femtocell BS , 也可以 称为个人基站）、 微基站 （Pico BS ), 即， 增加家庭小区 （ Femtocell Cell )、 微小区 （Pico Cell ) 等发射功率较低的小基站。 根据香农 ( Shannon ) 法则， 在釆用传统的宏基站进行覆盖的情况下， 会使频谱的占用量接近频谱使用的容量极限， 即使进一步增加功率较大的宏 基站， 也不会对室内覆盖有更多改善， 反而会造成更多的辐射污染。 而利用 Femtocell BS、 Pico BS等小基站， 不但可以很好地解决室内、 热点地区的覆 盖问题， 而且能够使用现有的频谱资源更大地提高系统容量。 其中， Femtocell BS可以为所有终端提供服务 （此时， 称 Femtocell BS 处于 open 状态）， 也可以只为一组特定的 ·ί受权终端提供 艮务 （此时， 称 Femtocell BS处于 close状态）， 此外， 根据是否支持向非自己授权终端提供 较低优先级的服务，处于 close状态的 Femtocell BS进一步分为 CSG-CLOSE 和 CSG-OPEN 两种状态。 通常， Femtocell BS 通过数字用户线 （Digital Subscriber Line, 简称为 DSL ) 与诸如接入服务网络、 连接服务网络等的上 层网元建立连接。 通常， 各种类型的基站（包括 Femtocell BS , Pico BS , Micro BS , Relay Station等）会根据其它网元的指示信息或自身实际情况决定是否使能切换功
能， 例如， 该基站自身负载过重或未与网络服务提供商签订相关协议或未及 时缴纳网络使用费用等。 在不了解目标切换基站是否使能切换功能的情况， 终端可能选择关闭了切换功能的基站作为自己的目标切换基站发起切换， 造 成切换时延和空口资源的浪费， 此外， 在切换失败时， 基站不会告知终端失 败原因 ,这进一步导致终端在已经关闭了切换功能的基站尝试进行多次接入， 这也会造成空口资源浪费。 发明内容 考虑到相关技术中存在的终端无法获知基站的切换能力信息的问题而提 出本发明， 为此， 本发明旨在提供一种信息传递方法、 基站及终端， 用以解 决上述问题。 根据本发明的一个方面， 提供了一种基于切换功能的信息传递方法。 在 该方法中， 基站向终端发送切换使能指示信息， 其中， 切换使能指示信息用 于指示基站是否支持切换功能。 优选地， 切换使能指示信息具体用于指示： 基站是否支持向一种或多种 类型的基站的切换。 优选地， 切换使能指示信息中还携带有以下至少之一： 基站支持切换到 的基站类型、 基站标识、 基站组标识、 同步信道序列索引中的一个或多个； 或者， 携带有以下至少之一： 基站不支持切换到的基站类型、 基站标识、 基 站组标识、 同步信道序列索引中的一个或多个。 优选地， 切换使能指示信息中还携带有： 基站支持切换功能的终端标识 和 /或终端组标识， 或者， 基站不支持切换功能的终端标识和 /或终端组标识。 优选地， 基站向终端发送切换使能指示信息的步骤包括： 基站响应终端 的请求消息， 并向终端发送响应消息， 所述响应消息携带切换使能指示信息 优选地， 上述方法还包括： 终端 居切换使能指示信息进行后续处理， 这里的后续处理包括以下至少之一： 选择接入基站或目标切换基站、 中止连 接建立过程。 根据本发明的另一方面， 提供了一种基于切换功能的信息传递方法。 在 该方法中， 终端向服务基站发送切换使能指示信息， 其中， 切换使能指示信
息用于指示终端是否支持由服务基站到其他基站的切换。 优选地， 切换使能指示信息具体用于指示如下之一： 终端是否支持向一 种或多种类型的基站的切换、 终端是否支持向一个或多个基站或基站组的切 换。 优选地， 切换使能指示信息中携带有以下至少之一： 终端支持切换到的 基站类型、 基站标识、 基站组标识、 同步信道序列索引中的一个或多个； 或 者， 携带有以下至少之一： 终端不支持切换到的基站类型、 基站标识、 基站 组标识、 同步信道序列索引中的一个或多个。 优选地， 上述方法还包括： 月艮务基站或其上层网元才艮据切换使能指示信 息生成邻区列表信息或者为终端选择接入基站或目标切换基站。 根据本发明的另一方面， 还提供了一种基站， 包括： 发送模块， 用于向 终端发送切换使能指示信息， 其中， 所述切换使能指示信息用于指示基站是 否支持切换功能。 根据本发明的另一方面， 还提供了一种终端， 包括： 发送模块， 用于向 服务基站发送切换使能指示信息， 其中， 所述切换使能指示信息用于指示终 端是否支持由所述服务基站到其他基站的切换。 通过本发明提供的上述至少一个技术方案， 终端可以获知基站的切换能 力信息， 或者， 基站可以获知终端的切换能力信息， 从而可以根据该切换能 力信息发起合适的切换过程或进行其他后续操作， 相比于现有技术， 可以提 高切换成功率， 提高空口资源利用率。 本发明的其它特征和优点将在随后的说明书中阐述， 并且， 部分地从说 明书中变得显而易见， 或者通过实施本发明而了解。 本发明的目的和其他优 点可通过在所写的说明书、 权利要求书、 以及附图中所特别指出的结构来实 现和获得。 附图说明 附图用来提供对本发明的进一步理解， 并且构成说明书的一部分， 与本 发明的实施例一起用于解释本发明， 并不构成对本发明的限制。 在附图中： 图 1是根据本发明实施例的在能力协商过程中传递切换使能指示信息的

BACKGROUND In a wireless communication system, a base station communicates with a device through an uplink/downlink, where downlink (forward) refers to the direction of the base station to the terminal, and uplink (reverse) refers to the direction of the terminal to the base station. In a typical application, multiple terminals can simultaneously transmit data to the base station through the uplink, or can simultaneously receive data from the base station through the downlink. Currently, in order to improve the quality of wireless coverage, the following two schemes are usually used for coverage: One method is to increase the number and density of macro base stations (Macs), that is, to increase the number and density of macro cells; The method is to install a home base station (Femtocell BS, also referred to as a personal base station) and a micro base station (Pico BS) indoors, that is, to increase a small cell (Femtocell Cell), a micro cell (Pico Cell), etc. Base station. According to Shannon's rule, when the traditional macro base station is used for coverage, the spectrum occupancy will be close to the capacity limit of the spectrum. Even if the macro base station with higher power is further increased, there will be no indoor coverage. More improvements will cause more radiation pollution. The use of small base stations such as Femtocell BS and Pico BS can not only solve the coverage problem indoors and hotspots, but also increase the system capacity by using existing spectrum resources. The Femtocell BS can provide services for all terminals (in this case, the Femtocell BS is in the open state), and can also provide services only for a specific set of authorized terminals (in this case, the Femtocell BS is in the close state). The Femtocell BS in the close state is further divided into two states, CSG-CLOSE and CSG-OPEN, depending on whether it supports the provision of lower priority services to non-authorized terminals. Generally, the Femtocell BS establishes a connection with an upper layer network element such as an access service network, a connection service network, or the like through a Digital Subscriber Line (DSL). Generally, various types of base stations (including Femtocell BS, Pico BS, Micro BS, Relay Station, etc.) will determine whether to enable switching according to the indication information of other network elements or their actual conditions. For example, the base station itself is overloaded or has not signed a relevant agreement with the network service provider or fails to pay the network usage fee in time. In the case that the target switching base station is enabled to enable the handover function, the terminal may select the base station that has turned off the handover function as its own target handover base station to initiate handover, resulting in a waste of handover delay and air interface resources. In addition, when the handover fails, the base station fails. The reason for the failure of the terminal is not informed, which further causes the terminal to attempt multiple accesses at the base station that has turned off the handover function, which also causes waste of air interface resources. SUMMARY OF THE INVENTION The present invention has been made in view of the problem that the terminal in the related art cannot know the handover capability information of the base station. To this end, the present invention aims to provide an information transmission method, a base station, and a terminal to solve the above problem.

Preferably, the handover enable indication information further carries: a terminal identifier and/or a terminal group identifier of the base station supporting the handover function, or a terminal identifier and/or a terminal group identifier of the handover function not supported by the base station.

Preferably, the method further includes: The handover enable indication information is used for subsequent processing, where the subsequent processing includes at least one of the following: selecting an access base station or a target handover base station, and aborting the connection establishment process.

Preferably, the handover enable indication information is specifically used to indicate one of: whether the terminal supports handover to one or more types of base stations, and whether the terminal supports handover to one or more base stations or groups of base stations. Preferably, the handover enable indication information carries at least one of the following: the terminal supports one or more of a base station type, a base station identifier, a base station group identifier, and a synchronization channel sequence index to which the handover is performed; or, carries at least one of the following : The terminal does not support one or more of the base station type, base station identity, base station group identity, and synchronization channel sequence index to which the handover is made. Preferably, the method further includes: the base station or the upper layer network element generating the neighbor list information according to the handover enable indication information or selecting the access base station or the target handover base station for the terminal.

Compared with the prior art, the handover success rate can be improved, and the utilization of air interface resources can be improved. Other features and advantages of the invention will be set forth in the description which follows, and The objectives and other advantages of the invention will be realized and attained by the <RTI The drawings are intended to provide a further understanding of the invention, and are intended to be a part of the description of the invention. In the drawings: FIG. 1 is a diagram of transmitting handover enable indication information in a capability negotiation process according to an embodiment of the present invention. 2 is a schematic diagram of a scenario in which a handover enable indication information is transmitted in a handover request interaction process; FIG. 3 is a structural block diagram of a base station according to an embodiment of the present invention; A structural block diagram of a terminal of an embodiment. BEST MODE FOR CARRYING OUT THE INVENTION Hereinafter, preferred embodiments of the present invention will be described with reference to the accompanying drawings, and the features of the embodiments and the embodiments of the present invention may be combined with each other if they do not conflict. As described above, at present, the terminal does not know whether the handover target is activated by the target base station to which the target base station is to be handed over or the handover service to which the handover request is initiated, and thus often causes the handover to fail or repeatedly initiates the handover. In view of this, an embodiment of the present invention provides an information transmission method, and specifically, a handover enable indication information transmission method is provided, which is configured to let a terminal know whether a base station or a selected target base station that requests a handover operation initiates a handover function. Or, the base station is configured to set a cause value based on the handover enable indication information in the handover reject message, so as to prevent the terminal from repeatedly initiating the handover. According to an embodiment of the present invention, an information transmission method is first provided, in which a base station
(例如， 终端向其发起切换请求的基站即服务基站） 将其自身的切换使能指 示信息， 也可以称为切换功能使能信息， 发送给终端， 该切换使能指示信息 用于指示该基站是否支持或开启了切换功能。 该切换使能指示信息的发送可 以由基站主动发起， 也可以响应于终端的请求而发起， 例如， 在终端注册到 基站的过程中发送， 在终端与基站的能力协商过程中发送， 或者， 在终端向 基站发送了切换请求消息之后发送， 发送的方式可以是通过广播信道、 组播 信道、 或单播信道等。 相关技术中， 终端可能选择关闭了切换功能的基站作为自己的目标切换 基站发起切换， 或者， 在切换失败时， 终端在已经关闭了切换功能的基站继 续尝试进行多次接入， 因为终端无法获知基站的切换能力信息， 导致空口资 源浪费。 通过本实施例， 终端可以通过切换使能指示信息获知基站的切换能 力，从而发起合适的切换过程或进行其他后续操作， 由此提高了切换成功率， 提高了空口资源利用率。
对于基站发送的上述切换使能指示信息， 除了可以指示基站是否支持切 换功能， 优选地， 还可以进一步用于进行如下指示： 基站是否支持向一种或 多种类型的基站切换、 基站支持切换的一种或多种基站类型、 基站不支持切 换的一种或多种基站类型。 这样， 终端可以更容易地根据切换使能指示信息 选择合适的基站进行相关的操作。 优选地， 切换使能指示信息中可以进一步携带有如下信息中的一个或多 个： 基站支持切换的终端标识或终端组标识、 基站不支持切换的终端标识或 终端组标识、 基站支持切换的基站标识或基站组标识、 基站不支持切换的基 站标识或基站组标识。 通过携带上述信息， 更方便终端对基站的切换功能有 直观的了解， 也就更便于决策进行后续操作。 对于终端而言， 其在接收到基站的切换使能指示信息后， 可以根据该切 换使能指示信息决定后续的处理流程， 例如， 可以选择合适的接入基站或目 标切换基站等。 以下分别结合实施例进行描述。 需要说明的是， 在下文中， 基站类型、 基站 BS-A、 BS-B、 BS-C可以包括宏基站、 Femtocell基站、 Pico基站、 Micro 基站等， 其中 Femtocell基站可进一步分为 CSG-OPEN、 CSG-CLOSE、 OPEN 等基站类型。在下文中提到的下行信道，可以是超帧头（ Super Frame Header )、 广播控制消息、 或单播控制消息。 方法实施例 1 基站 BS-A通过下行信道向终端发送切换使能指示信息， 假设该切换使 能指示信息指示基站 BS-A不支持切换功能， 或者， 没有开启切换功能， 则 以该基站为月艮务基站的终端不向该基站发送切换请求消息。 方法实施例 2 基站 BS-A通过下行信道向终端发送切换使能指示信息， 假设该信息指 示基站 BS-A不支持切换功能， 则接收到该信息的不以该基站为服务基站的 终端将不会选择该基站作为接入基站或切换的目标基站。 方法实施例 3 基站 BS-A通过下行信道传输切换使能指示信息， 假设该信息例如通过 bitmap的方式表示基站 BS-A不支持向宏基站类型、 和 /或 Femtocell基站类
型 （可进一步分为 CSG-OPEN、 CSG-CLOSE、 OPEN 等基站类型）、 和 /或 Pico基站类型、 和 /或 Micro基站类型的基站的切换功能， 则以该基站为服务 基站的终端， 根据上述的切换使能指示信息， 不选择宏基站类型、 Femtocell 基站类型、 Pico基站类型、 Micro基站类型中的一个或多个类型的基站作为 自己切换的目标基站。 方法实施例 4 基站 BS-A通过下行信道传输切换使能指示信息， 假设该信息例如通过 bitmap的方式指示基站 BS-A不支持向宏基站类型、 和 /或 Femtocell基站类 型 （可进一步分为 CSG-OPEN、 CSG-CLOSE、 OPEN 等基站类型）、 和 /或 Pico基站类型、 和 /或 Micro基站类型的基站的切换功能， 则该基站不选择宏 基站类型、 和 /或 Femtocell基站类型、 和 /或 Pico基站类型、 和 /或 Micro基 站类型的基站作为以自己为 艮务基站的终端的目标切换基站。 方法实施例 5 基站 BS-A通过下行信道传输切换使能指示信息， 假设该信息指示基站 BS-A 不支持向宏基站类型、 和 /或 Femtocell 基站类型 （可进一步分为 CSG-OPEN、 CSG-CLOSE、 OPEN等基站类型）、 和 /或 Pico基站类型、 和 / 或 Micro基站类型的基站的切换功能， 则对于接收到该信息且没有以该基站 为月艮务基站的终端， 不选择该基站作为接入基站。 方法实施例 6 基站 BS-A通过下行信道传输切换使能指示信息， 假设该信息指示基站(For example, the base station to which the terminal initiates the handover request, that is, the serving base station), its own handover enable indication information, which may also be referred to as handover function enable information, is sent to the terminal, and the handover enable indication information is used to indicate the base station. Whether the switching function is supported or turned on. The sending of the handover enable indication information may be initiated by the base station, or may be initiated in response to the request of the terminal, for example, during the process of the terminal registering with the base station, during the capability negotiation process between the terminal and the base station, or After the terminal sends a handover request message to the base station, the method may be sent through a broadcast channel, a multicast channel, or a unicast channel. In the related art, the terminal may select the base station that has turned off the handover function as its own target handover base station to initiate handover, or, when the handover fails, the terminal continues to try multiple accesses at the base station that has turned off the handover function, because the terminal cannot know. The switching capability information of the base station causes waste of air interface resources. In this embodiment, the terminal can learn the handover capability of the base station by switching the enable indication information, thereby initiating a suitable handover process or performing other subsequent operations, thereby improving the handover success rate and improving the utilization of the air interface resource. For the above-mentioned handover enable indication information sent by the base station, in addition to indicating whether the base station supports the handover function, it may be further used to perform the following indication: whether the base station supports handover to one or more types of base stations, and the base station supports handover.

The base station included in the Group BS-D acts as a target handover base station with its own terminal for the base station. Method Embodiment 8 The base station BS-A transmits handover enable indication information through a downlink channel, assuming that the information indicates that the base station BS-A does not support handover to a specific base station BS-B, BS-C, and/or base station group Group BS-D. Then, the terminal that receives the information and does not use the base station BS-A as the serving base station does not select the base station as the access base station. Method Embodiment 9 As shown in FIG. 1, the terminal MS-A performs capability negotiation with the base station BS-A, and the base station BS-A includes handover enable indication information in the negotiation message, where the information is used to indicate whether the base station BS-A supports handover. Features. If the information indicates that the base station BS-A does not support the handover function, the terminal MS-A does not subsequently send a handover request message to the base station BS-A. Method Embodiment 10 The terminal MS-A performs capability negotiation with the base station BS-A. The base station BS-A includes handover enable indication information in the negotiation message, and the information indicates whether the base station BS-A supports the handover function. If the information indicates that the base station BS-A does not support the handover function, the terminal MS-A suspends the connection establishment procedure with the base station BS-A, and reselects the appropriate base station as its own serving base station. Method embodiment 11: The terminal MS-A and the base station BS-A perform capability negotiation. The base station BS-A includes handover enable indication information in the negotiation message, where the information indicates whether the base station BS-A supports handover to other base station type base stations. The base station type here includes a macro base station, a Micro base station, a Pico base station, a Femtocell base station, and the like. For example, the handover enable indication information sent by the base station BS-A may indicate that the base station supports handover to the base station of the macro base station type, but does not support handover to the base station of the femocell base station type. Method Embodiment 12 As shown in FIG. 2, the terminal MS-A sends a handover request message to the base station BS-A. If the base station BS-A does not support the handover function, the BS-A rejects the handover request of the terminal, and in the response message. Carrying the handover enable indication information (ie, carrying the handover rejection reason), indicating that the handover function is not supported by itself. The terminal MS-A that has received the response message no longer sends a handover request message to the base station BS-A. In this way, it is avoided to repeatedly initiate the handover. Method embodiment 13: The terminal MS-A sends a handover request message to the base station BS-A. If the base station BS-A does not support the handover function, the BS-A rejects the handover request of the terminal, and carries the handover enable indication information in the response message. (Can also be understood as the reason for the handover rejection), indicating that it does not support the macro base station type, and/or the Femtocell base station type (which can be further classified into CSG-OPEN, CSG-CLOSE, OPEN, etc.), and/or Pico base station type. And/or the switching function of the base station of the Micro base station type. The terminal MS-A that has received the response message selects an appropriate base station as its own target handover base station among the handover base station types supported by the base station BS-A, and transmits a handover request message to the base station BS-A again. Method Embodiment 14: A base station BS-A transmits handover enable indication information, where the information includes one or more specific terminals, or one or more specific groups, that the base station supports handover to base stations of other one or more base station types. The identification information of the terminal, where the specific terminal or the terminal group may be a user with a large amount of payment, or a special user group set by the operator. The terminal MS-A receives the handover enable indication information. If the terminal identifier or the terminal group identifier is the same as the corresponding field in the foregoing information, the terminal may switch from the base station to another one or more of the base station BS-A supporting handover. Types of base stations. The terminal MS-B receives the handover enable indication information. If the terminal identifier or the terminal group identifier is different from the corresponding field in the foregoing information, the terminal MS-B may not switch from the base station BS-A to the base station BS-A. One or more other types of base stations that are switched. Method Embodiment 15: A base station BS-A transmits handover enable indication information, where the information includes one or more specific terminals, or one or more specific groups, that the base station does not support handover to base stations of other one or more base station types. The identification information of the terminal, where the specific terminal or the terminal group may be a user with less payment, or a special user group set by the operator. The terminal MS-A receives the handover enable indication information. If the terminal identifier or the terminal group identifier is the same as the corresponding field in the foregoing information, the terminal MS-A may not switch from the base station BS-A to the base station BS-A. One or more other types of base stations that are switched. The terminal MS-B receives the handover enable indication information. If the terminal identifier or the terminal group identifier is different from the corresponding field in the foregoing information, the terminal MS-B can switch from the base station BS-A to the base station BS-A to support handover. One or more other types of base stations. It can be seen that the base station sends the handover enable indication information to the terminal, and the subsequent base station or terminal can select a suitable access base station or the handover target base station according to the basis, and can also determine whether it is currently The serving base station initiates a handover request. Compared with the prior art, the success rate and efficiency of handover are improved, and air interface resources are saved. The method described above is a method for a base station to send its handover enable indication information to a terminal. In the embodiment of the present invention, a method for a terminal to send its handover enable indication information to a base station is provided. The handover enable indication information is used to indicate Whether the terminal supports the handover function, and preferably, is further used to indicate whether the terminal supports handover to one or more types of base stations, one or more base stations or base station groups, and the like. Preferably, the handover enable indication information may further carry a base station type to which the terminal supports handover or a base station type that does not support handover; or, carry a base station or a base station group list that the terminal supports/does not support handover. In the related art, because the base station cannot learn the handover capability information of the terminal, the air interface resource in the handover process is wasted. In this embodiment, the base station can learn the handover capability of the terminal by switching the enable indication information, thereby performing an appropriate handover process, thereby improving the handover success rate and improving the utilization of the air interface resource. The detailed description will be made below in conjunction with the embodiments. Similar to the process in which the base station sends the handover enable indication information, in the embodiment of the present invention, the terminal may actively send the handover enable indication information, as in the embodiment 16 to the embodiment 20, or may send the handover enable in response to the request of the base station. The indication information is as in Example 21 and Example 22. Method Embodiment 16 The terminal MS-A sends a handover enable indication message to the base station BS-A, indicating that it does not support the type of femtocell base station (which can be further divided into base station types such as CSG-OPEN, CSG-CLOSE, and OPEN), and the type of the macro base station. Base station handover of one or more of the Micro base station type and the Pico base station type, the base station BS-A or the upper layer network element (for example, the access service network network element, the connection service network network element, etc.) based on the information as the terminal MS-A The neighbor list information of the base station of the base station type not including the above-mentioned terminal does not support handover is generated. Method Embodiment 17 The terminal MS-A sends a handover enable indication message to the base station BS-A, indicating that it does not support the type of femtocell base station (which can be further divided into base station types such as CSG-OPEN, CSG-CLOSE, OPEN), and the type of the macro base station. Base station handover of one or more of the Micro base station type and the Pico base station type, the base station BS-A or the upper layer network element (for example, the access service network network element, the connection service network network element, etc.) based on the information as the terminal MS-A A suitable handover target base station is selected, where the appropriate target base station does not include the above-mentioned base station type in which the terminal does not support handover. Method Embodiment 18: The terminal MS-A sends a handover enable indication information to the base station BS-A, indicating that it does not support handover to the base station group Group BS-A (including the base stations BS-A, BS-B, BS-C). The base station BS-A or the upper layer network element (for example, the access service network network element, the connection service network network element, etc.) generates a neighboring cell that does not include the base stations BS-A, BS-B, and BS-C for the terminal MS-A based on the information. List information. Method embodiment 19: The terminal MS-A sends handover enable indication information to the base station BS-A, indicating that it does not support handover to the base station group Group BS-A (including the base stations BS-A, BS-B, BS-C), and then the base station The BS-A or the upper network element (for example, the access service network element, the connection service network element, etc.) selects a suitable target handover base station for the terminal MS-A based on the information, and the target handover base station does not include the base station group Group BS-A. Base station in. Method Embodiment 20: The terminal MS-A sends a handover enable indication information to the base station BS-A to indicate that it does not support handover, that is, does not support handover to any other base station, and the base station BS-A that receives the information does not go to the terminal MS- A recommends any target switching base station. Method embodiment 21: The base station BS-A sends a handover enable function request message to the terminal MS-A. After receiving the request message, the terminal MS-A sends a handover enable indication information to the base station BS-A, the base station BS-A or the upper layer. The network element (for example, the access service network element, the connection service network element, etc.) selects a suitable target handover base station for the terminal MS-A based on the information. Method embodiment 22: The base station BS-A sends a handover enable function request message to the terminal MS-A. After receiving the request message, the terminal MS-A sends a handover enable indication information to the base station BS-A, the base station BS-A or the upper layer. The network element (for example, the access service network element, the connection service network element, etc.) generates a suitable neighbor list for the terminal MS-A based on the information. With this embodiment, the terminal provides its handover enable indication information to the base station, so that the base station or its upper layer network element can generate a suitable neighbor list for the terminal, and select a suitable access base station or target handover base station for the terminal. Compared with the prior art, the handover success rate can be improved, and the utilization of air interface resources can be improved. The above is an example of the information exchange process between the base station and the terminal. It is easy to understand that a similar direct transmission or forwarding process can be performed between the base station and the base station. For example, the base station BS-A sends its handover enable indication information. To the base station BS-B, if the handover enable indication information indicates that the base station BS-A does not support handover, the subsequent base station BS-B may reject the handover request message sent by the terminal with the base station BS-A as the target base station. The request, and indicating in the handover request rejection message, that the base station BS-A does not support handover, can be implemented by carrying the identifier of the base station BS-A and the identifier not supporting the handover in the handover request rejection message.
