Description
区域转换方法及系统 Regional conversion method and system
技术领域 本发明涉及移动通信技术领域， 尤其涉及一种区域转换方法及系统。 背景技术 目前， 无线通信系统使用电磁波和移动的或者固定的无线通信终端进行 通信。 在进行无线通信时， 终端通常位于系统的无线覆盖范围之内， 并通过 无线通信信道与系统进行通信。 无线通信信道将电磁波频率分成多个载波频 率， 一个载波频率就是一个无线通信信道。 无线通信系统通过基站 （Base Station, 筒称为 BS ) 利用指定的无线信道在一定地理范围内提供无线覆盖， 这个地理范围称为小区 （Cell )。 通常， 基站位于小区的中央。 终端从一个小 区移动到另一个小区时， 为了保持通信， 需要进行基站的切换。 目前， 已经出现了先进基站 （Advanced Base Station, 筒称为 ABS ), 先 进基站能够兼容传统终端， 同样地， 先进终端（Advanced Mobile Station, 筒 称为 AMS ) 也应该能够接入传统基站。 先进基站的时间区域（Time Zone ) 可以分成两个区 i或， 即， 第一区 i或 （也称为先进区 i或， 16m Zone , 筒称为 MZone ) 和第二区 i或（也称为传统区 i或 , Legacy Zone , 筒称为 LZone )。 先 进终端可以工作在第一区域， 传统终端可以工作在第二区域。 由于先进终端 可以采用最新通信协议或传统协议， 因此， 先进终端就可以工作在第一区域 或第二区域， 这样就出现了在第一区域和第二区域转换的问题。 此类切换可 以称为区域转换 （Zone Switch ), 服务站 （也可以说是服务区域） 和目标站 (也可以说是目标区域）是基站的不同区域， 因此在下文中， 除非特殊说明， 转换 （Switch ) 和切换 （Handover, Handoff ) 指示的动作是一样的。 先进控制站 （支持 IEEE802.16m 协议的基站 /中继站） 能够兼容支持传 统移动站 （支持 IEEE802.16e 协议的移动站）， 同样地， 先进移动站 （支持 IEEE802.16m协议的移动站 )也应该能够接入传统控制站（支持 IEEE802.16e 的基站或支持 IEEE802.16j的中继站）。 第一区 i或支持 IEEE 802.16m定义的 新的通信协议， 第二区域可以支持 IEEE802.16e/16j的协议。 此外， 先进控制 站也可以只能接入先进终端，即，只支持 IEEE 802.16m定义的新的通信协议。
为了提高无线通信系统的数据传输速率 , 提出了多载波技术。 先进基站 可以支持多载波操作， 在多载波无线通信系统的协议架构下， 统一的媒体接 入控制实体（ Media Access Control, 筒称为 MAC )控制包括多个信道（信道 1、 信道 2 信道 N ) 的物理层 （Physical layer, 筒称为 PHY )。 其中， 每个信道可以有不同的带宽， 这里的带宽可以是连续或不连续的频带。 在支持多载波操作的无线通信系统中， 对基站而言， 载波可以分为全配 置载波和部分配置载波。其中，全配置载波是指配置了所有控制信道的载波， 上述的控制信道包括同步信道、 广播信道、 组播信道和单播信道， 还包括与 多载波操作及其他载波的信息和参数相关的信道。 因此， 终端进行网络接入 的过程一定在全配置载波上进行； 对于终端来说， 进行网络接入的全配置载 波称为主载波。 部分配置载波是指只配置了在多载波操作中用于支持业务交 互的基本的控制信道的载波。全配置载波可以作为终端的主载波或者辅载波 , 部分配置载波仅可以作为终端的辅载波。 在一个小区中， 每个终端只有一个 主载波， 可以有一个或多个辅载波， 也可以没有辅载波。 目前支持多载波操作的先进终端可以分为单通道 ( single radio ) 终端和 多通道（multiple radio ) 终端两种。 一个通道对应于物理层的一个射频模块 ( Radio Frequency, 筒称为 RF ), —个通道可以工作在系统的一个载波频点 上。 根据现有技术，先进基站和先进基站的第一区域的邻区广播消息（例如： AAI-NBR-ADV )只广播邻区先进基站和邻区先进基站第一区域的系统信息。 因此， 工作在先进基站第一区域下的先进终端如果决定移动到先进基站的第 二区域以获得更好的服务， 由于无法从第一区域的邻区广播消息中获取该先 进基站的第二区域的系统信息 , 需要使用自己的一个或多个通道对第二区域 进行盲扫， 获取其系统信息。 这种盲扫的方式耗时久、 效率低， 增加了区域 转换过程所需要的时间。 发明内容 考虑到相关技术中存在的先进终端在转换到当前基站的其他区域时获取 系统信息的方式耗时久、 效率低的问题而提出本发明， 为此， 本发明的主要 目的在于提供改进的区域转换方案， 以解决上述问题至少之一。 才艮据本发明的一个方面， 提供了一种区域转换方法。
对于工作在先进基站的第一区域下的先进终端， 才艮据本发明的区域转换 方法包括： 先进基站在所述第一区域向所述先进终端发送消息， 其中， 该消 息中包括该先进基站的第二区域的信息； 先进终端才艮据该信息， 进行从上述 第一区域到上述第二区域的区域转换。 根据本发明的另一个方面， 提供了一种区域转换系统。 才艮据本发明的区域转换系统包括： 先进基站和先进终端。 其中， 先进基 站， 用于在其第一区域向先进终端发送消息， 其中， 该消息中包括该先进基 站的第二区域的信息； 先进终端， 用于接收先进基站发送的上述消息， 并根 据该第二区域的信息， 进行从第一区域到第二区域的区域转换。 通过本发明的上述至少一个方案， 通过先进基站在其第一区域上向先进 终端发送包含该基站的第二区域的信息的消息， 使得先进终端可以在第一区 域获取第二区域的信息， 进而切换到第二区域， 从而避免了以盲扫的方式获 取第二区域的系统信息， 提高了区域转换的效率。 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为根据本发明实施例的区域转换方法的流程图； 图 2为实施例一的流程图； 图 3为实施例二的流程图； 图 4为实施例三的流程图； 图 5为实施例四的流程图； 图 6为实施例五的流程图；

先进终端盲扫的操作， 从而提高区域转换效率。 在具体实施过程中， 先进基站可以主动向该先进终端发送该消息 （即先 进基站确定该先进终端需要进行区域转换 ),也可以是在接收到来自该先进终 端的请求消息时， 响应于该请求消息， 向该先进终端发送上述消息 （即先进 终端确定需要进行区域转换）， 其中，先进终端发送的该请求消息用于请求系 统信息， 例如， 第二区域的载波信息。 优选地， 该请求消息可以为测距请求 消息 （ AAI-RNG-REQ )。 并且， 如果是先进终端确定需要进行区域转换， 则先进终端发送的上述 请求消息中可以携带 （当然也可以不携带） 目的值为区域转换的参数项； 对应地， 先进基站发送的上述消息可以是以下消息之一： 切换命令消息The present invention relates to the field of mobile communication technologies, and in particular, to a region conversion method and system. Background Art Currently, wireless communication systems use electromagnetic waves to communicate with mobile or fixed wireless communication terminals. In wireless communication, the terminal is typically located within the wireless coverage of the system and communicates with the system over a wireless communication channel. The wireless communication channel divides the electromagnetic wave frequency into a plurality of carrier frequencies, and one carrier frequency is a wireless communication channel. The wireless communication system provides wireless coverage in a certain geographical range by using a designated wireless channel through a base station (base station), and this geographical range is called a cell. Typically, the base station is located in the center of the cell. When a terminal moves from one cell to another, in order to maintain communication, handover of the base station is required. At present, advanced base stations (ABSs) have emerged, and advanced base stations can be compatible with traditional terminals. Similarly, advanced terminals (Advanced Mobile Stations, called AMSs) should also be able to access traditional base stations. The time zone of the advanced base station can be divided into two zones i or, that is, the first zone i or (also known as the advanced zone i or 16m Zone, the cylinder is called MZone) and the second zone i or (also called For the traditional zone i or Legacy Zone, the cartridge is called LZone). The advanced terminal can work in the first area, and the traditional terminal can work in the second area. Since the advanced terminal can adopt the latest communication protocol or the conventional protocol, the advanced terminal can work in the first area or the second area, so that the problem of switching between the first area and the second area occurs. Such a handover can be referred to as a zone switch (Zone Switch), a service station (also arguably a service zone) and a target station (also arguably a target zone) are different zones of the base station, so in the following, unless otherwise specified, the conversion ( Switch ) and the action indicated by Handover, Handoff are the same. Advanced control station (base station/relay station supporting IEEE802.16m protocol) is compatible with supporting traditional mobile stations (mobile stations supporting IEEE802.16e protocol). Similarly, advanced mobile stations (mobile stations supporting IEEE802.16m protocol) should also be able to Access to legacy control stations (base stations supporting IEEE802.16e or relay stations supporting IEEE802.16j). The first zone i or a new communication protocol defined by IEEE 802.16m, the second zone may support the IEEE 802.16e/16j protocol. In addition, advanced control stations can only access advanced terminals, ie, only new communication protocols defined by IEEE 802.16m. In order to improve the data transmission rate of a wireless communication system, a multi-carrier technique is proposed. The advanced base station can support multi-carrier operation. Under the protocol architecture of the multi-carrier wireless communication system, the unified media access control entity (Media Access Control, called MAC) control includes multiple channels (channel 1, channel 2 channel N) The physical layer (the physical layer, called the PHY). Each channel may have a different bandwidth, and the bandwidth here may be a continuous or discontinuous frequency band. In a wireless communication system supporting multi-carrier operation, for a base station, a carrier can be divided into a fully configured carrier and a partially configured carrier. The fully configured carrier refers to a carrier configured with all control channels, and the foregoing control channels include a synchronization channel, a broadcast channel, a multicast channel, and a unicast channel, and also includes channels related to information and parameters of multi-carrier operation and other carriers. . Therefore, the process of the terminal performing network access must be performed on the fully configured carrier; for the terminal, the fully configured carrier for performing network access is referred to as the primary carrier. A partially configured carrier refers to a carrier that is only configured with a basic control channel for supporting traffic interactions in multi-carrier operation. The fully configured carrier can serve as the primary carrier or secondary carrier of the terminal, and the partially configured carrier can only serve as the secondary carrier of the terminal. In a cell, each terminal has only one primary carrier, and may have one or more secondary carriers or no secondary carriers. The advanced terminals that support multi-carrier operation can be divided into single-channel (single-radio) terminals and multi-channel (multi-radio) terminals. One channel corresponds to one radio frequency module of the physical layer (Radio Frequency, called RF), and one channel can work at one carrier frequency of the system. According to the prior art, the neighboring area broadcast message (for example, AAI-NBR-ADV) of the first area of the advanced base station and the advanced base station broadcasts only the system information of the neighboring area advanced base station and the neighboring area advanced base station first area. Therefore, if the advanced terminal working in the first area of the advanced base station decides to move to the second area of the advanced base station to obtain better service, the second area of the advanced base station cannot be obtained from the neighboring area broadcast message of the first area. System information, you need to use your own one or more channels to blindly scan the second area to get its system information. This method of blind scanning is time consuming and inefficient, increasing the time required for the regional conversion process. SUMMARY OF THE INVENTION The present invention has been made in view of the problem that the advanced terminal existing in the related art acquires system information in a time-consuming and inefficient manner when switching to other areas of the current base station, and for this reason, the main object of the present invention is to provide an improved A regional conversion program to address at least one of the above issues. According to an aspect of the present invention, a region conversion method is provided. For the advanced terminal operating in the first area of the advanced base station, the area conversion method according to the present invention includes: the advanced base station transmitting a message to the advanced terminal in the first area, wherein the message includes the advanced base station The information of the second area; the advanced terminal performs the area conversion from the first area to the second area according to the information. According to another aspect of the present invention, a zone conversion system is provided. The area conversion system according to the present invention includes: an advanced base station and an advanced terminal. The advanced base station is configured to send a message to the advanced terminal in the first area, where the message includes the information of the second area of the advanced base station, and the advanced terminal is configured to receive the foregoing message sent by the advanced base station, and according to the The information of the second area performs area conversion from the first area to the second area. With the above at least one aspect of the present invention, the advanced base station transmits a message including the information of the second area of the base station to the advanced terminal on the first area thereof, so that the advanced terminal can acquire the information of the second area in the first area, and further Switching to the second area avoids acquiring the system information of the second area in a blind scan manner, thereby improving the efficiency of the area conversion. 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. 1 is a flowchart of a region conversion method according to an embodiment of the present invention; FIG. 2 is a flowchart of Embodiment 1; FIG. 3 is a flowchart of Embodiment 2; Figure 5 is a flow chart of the fourth embodiment; Figure 6 is a flow chart of the fifth embodiment; FIG. 7 is a structural block diagram of a region conversion system according to an embodiment of the present invention. In the prior art, the neighboring area broadcast message of the first area of the advanced base station and the advanced base station only broadcasts the system information of the neighboring area advanced base station and the neighboring area advanced base station first area, and therefore works first in the advanced base station. The advanced terminal of the area cannot obtain the system information of the second area of the advanced base station from the neighboring area broadcast message, and needs to use one or more channels of its own to blindly scan the second area to obtain system information, thereby reducing area conversion. In view of this, the embodiment of the present invention provides a region conversion scheme. In the embodiment of the present invention, the advanced base station sends a message to the advanced terminal in the first area for the advanced terminal working in the first area of the advanced base station, where the message includes the information of the second area of the advanced base station, where After receiving the message, the advanced terminal performs area conversion from the first area to the second area of the advanced base station according to the instruction of the message. The preferred embodiments of the present invention are described below with reference to the accompanying drawings, and the features of the embodiments and the embodiments of the present invention can be combined with each other if they do not conflict. In the embodiment of the present invention, the terminals involved include, but are not limited to, a mobile radiotelephone, a notebook computer with a wireless communication card, a personal digital assistant, and the like.

Conversion of the first area to the second area. In the related art, the advanced terminal working in the first area of the advanced base station cannot acquire the system information of the second area of the advanced base station. Therefore, the advanced terminal needs to perform blind scanning on the second area, but this reduces the area conversion efficiency. . In the embodiment of the present invention, the advanced base station sends a message carrying the information of the second area of the advanced base station to the advanced terminal working in the first area, which can be avoided. Advanced terminal blind sweep operation, thereby improving regional conversion efficiency. In a specific implementation process, the advanced base station may actively send the message to the advanced terminal (ie, the advanced base station determines that the advanced terminal needs to perform area conversion), or may respond to the request when receiving the request message from the advanced terminal. The message is sent to the advanced terminal (that is, the advanced terminal determines that area conversion is required), wherein the request message sent by the advanced terminal is used to request system information, for example, carrier information of the second area. Preferably, the request message may be a ranging request message (AII-RNG-REQ). In addition, if the advanced terminal determines that the area conversion needs to be performed, the request message sent by the advanced terminal may be carried (of course, may not be carried). The destination value is a parameter item of the area conversion; correspondingly, the foregoing message sent by the advanced base station may be One of the following messages: Switch command message
