Description

一种通信方法、 多模终端和基站及系统
本申请要求于 2011年 8月 2日提交中国专利局、申请号为 201110219913.9、 发明名称为"一种通信方法、 多模终端和基站及系统"的中国专利申请的优先 权， 其全部内容通过引用结合在本申请中。
技术领域
本发明涉及无线通信领域， 尤其涉及一种通信方法、 多模终端和基站及系 统。 背景技术
随着通信技术的飞速发展，越来越多的无线应用被开发出来， 以丰富人们 的生活和沟通，但维持无线通信的可用频谱资源是有限的， 随着无线应用的增 多， 无线频谱资源日益紧缺。 因此， 提高无线频谱利用率成为目前无线通信所 面临的主要挑战。
目前各国的无线频谱分配是按照固定分配的方式，将频谱分割为多段互不 重叠的频段，分配给特定的运营商用于开展特定的无线应用的频段称之为授权 频段， 没有授权给特定的运营商、任何满足无线管理委员会设定要求的设备都 可以用来通信的频段称为非授权频段。
目前， 一般远距离通信都使用授权频段， 其普遍采用系统设备（如基站、 基站控制器、 核心网）为中心的架构， 用户设备（如手机）之间的通信， 都要 经过系统设备的转发。 使用授权频段的通信中， 通信资源由网络集中调度， 通 信质量可以得到保证，但通信的费用一般较高。 近距离通信则大都采用非授权 频段，使用非授权频段进行的通信一般要采用冲突检测和规避的策略， 用户在 使用非授权频段时， 需要首先检测频段的忙闲情况， 只有在频段空闲时才可以 使用， 如果检测到频段被占用， 则会随机的等待一段时间后再进行检测， 直到 检测到有空闲的频段后才可以发送数据，且在完成一个通信后，要立即译放信 道。 这种通信方式如果在用户数较多， 频段较为拥挤的情况下， 需要等待较长 的时间， 通信质量无法保证， 但通信费用较低。 随着用户无线业务的飞速发展， 越来越多的终端同时集成了多个通信协 议， 例如很多终端都集成了宽带码分多址（WCDMA , Wideband Code Divi s ion Mul t i ple Acces s )协议和无线宽带接入技术 ( WLAN , wi re les s loca l acces s network,也称为 WIFI标准）协议。用户在有 WIFI部署的热点区域，使用 WIFI 接入因特网 （Internet ), 在无 WIFI 部署或者需要语音通信时， 使用 WCDMA 协议接入 Internet或者进行语音通信， 非授权频段由于费用较低， 使用用户 数很多，频段很拥挤，在用户数很多时，无法满足正常的通信要求。 另一方面， 授权频段由于用户独占使用频谱，在用户较少的情况下，会有大量的频谱空闲， 这对于宝贵的频谱资源是一种浪费。
为了解决这个问题，现有技术提出了机会频语接入的机制， 或者称为认知 无线电 （CR, Cogni t ive Radio ), 在这种机制中， 将获得了授权频段使用权的 用户称为授权用户， 没有获得授权频段使用权的用户称之为非授权用户。在机 会频语接入方式中， 非授权用户可使用没有被授权用户所占用的空闲频谱资 源。 具体地， 非授权用户可检测没有被授权用户所占用的空闲频率资源， 利用 所检测到的空闲频谱资源实现非授权用户之间的无线通信。这种技术可以使用 空闲的授权频段， 有效提高的频谱利用率。 采用能量检测， 进行频谱扫描， 如果某段频谱的能量低于特定的门限， 则认为 该频谱空闲，一方面， 非授权用户可能会没有检测到距离较远的授权用户的通 信， 而将某个频段误判为空闲频段而使用， 结果干扰到授权用户的通信； 另一 方面， 由于授权用户的频语是动态变化的， 可能在检测的时候频段是空闲的， 但在非授权用户使用该频段时， 授权用户可能会发起通信， 这种情况下， 非授 权用户也会对授权用户造成干扰。 发明内容

本发明实施例提供了一种通信方法、 多模终端和基站及系统， 用于实现基 于非授权频段协议标准的通信， 并避免对授权用户的干扰。 需要说明的是， 本 发明背景技术和实施例中的授权用户和非授权用户都是指用户设备 ( UE ), 因 此实施例中的用户应理解为是一种通信设备， 而不是一个实际的人， 所述用户 设备可包括但不限于各类通信终端。在各类通信终端中， 多模终端可以是能够 兼容多种协议标准的终端 ,在本发明实施例中的第一多模终端能够同时兼容授 权频段协议标准和非授权频段协议标准。例如， 本实施例中提到的终端可兼容 LTE标准和短距离通信协议。
为使得本发明的发明目的、 特征、 优点能够更加的明显和易懂， 下面将结 合本发明实施例中的附图，对本发明实施例中的技术方案进行清楚、 完整地描 述，显然，下面所描述的实施例仅仅是本发明一部分实施例，而非全部实施例。 基于本发明中的实施例， 本领域的技术人员所获得的所有其他实施例，都属于 本发明保护的范围。
本发明实施例提供的一种通信方法， 如图 1所示， 包括：
101、 第一多模终端从授权频段网络获取可以以机会频语接入方式使用的 授权频段资源。
在本发明实施例中， 第一多模终端同时集成有多个通信协议， 这些通信协 议分为两类。 其中， 一类通信协议是授权频段通信协议标准， 简称授权频段协 议标准，在这类标准中授权频段被分配给特定的授权频段网络用于通信，通常 是用于远距离通信网络， 例如， 支持的授权频段通信协议标准包括： 全球移动 通讯系统 ( GSM , Global System of Mobile communication )协议标准、 码 分多址接入（ CDMA, Code Division Multiple Access ) 2000协议标准， 宽带 码分多址接入 ( WCDMA, Wideband Code Division Multiple Access )协议标 准、 高速分组接入（HSPA, High Speed Packet Access )协议标准、 演进式 高速分组接入 ( HSPA+, High Speed Packet Access Evolution )协议标准、 长期演进（LTE, Long Term Evolution )协议标准、 高级长期演进（ LTE-A, Long Term Evolution-Advanced )协议标准、 802.16e协议标准、 802.16m协 议标准、全球 波互联接入（ WiMax, Worldwide Interoperability for Microwave Access )协议标准， 本发明实施例中的第一多模终端具体可以支持其中的一 个或多个授权频段通信协议标准。 授权频段网络 于授权频段协议标准的。 该授权频段网络可以包括无线接入网中的服务节点，授权频段网络掌握其授权 频段资源的使用权。 另一类通信协议是非授权频段通信协议标准， 简称为非授 权频段协议标准，在这类标准通常中非授权频段不会被分配给特定的网络， 可 以被满足预设要求的任意网络使用。例如， 支持的非授权频段通信协议标准包 括： 无线相容认证 ( WIFI , wireless fidelity )协议标准、 蓝牙 ( bluetooth )协 议标准、 802.15.4 ( Zigbee )协议标准， 本发明实施例中的第一多模终端具体 可以支持其中的一个或多个非授权频段通信协议标准。
在本发明实施例中，同时支持授权频段通信协议标准和非授权频段通信协 议标准的第一多模终端在具体实现时，可以在第一多模终端内部设置授权频段 通信模块 (相当于现有技术中的授权用户 )和非授权频段通信模块 (相当于现 有技术中的非授权用户）。 本发明实施例中的机会频语接入方式为第一多模终 端中的非授权频段通信模块使用授权频段通信模块从授权频段网络获取的授 权频段资源进行通信。 第一多模终端从授权频段网络获取授权频段资源， 这与 现有技术中由非授权用户自主测量授权用户的空闲状态是不同的，可以避免非 授权用户的误判，故可以避免非授权用户对授权用户的干扰。 第一多模终端可 具体从授权频段网络中的基站处获取授权频段资源。在本实施例中， 多模终端 可以以机会频语接入方式使用该授权频段资源，表明该多模终端有能力使用该 授权频段资源。
需要说明的是， 在本发明实施例中， 101之前还可以进一步包括， 第一多 模终端和第二多模终端要相互交互彼此的能力， 例如可以在非授权频段网络， 第一多模终端和第二多模终端交互彼此的能力， 双方交互的能力可以包括： 支 持的通信协议标准有哪些，是否支持以机会频语接入方式使用授权频段资源的 能力。
在本发明实施例中，还可以进一步的包括， 第一多模终端与第二多模终端 协商进入机会频语接入通信模式，在实际应用中， 第一多模终端和第二多模终 端的首选工作频段都是非授权频段， 在多模终端发现非授权频段比较拥挤时， 需要通信的双方就可以相互协商进行机会频语接入通信模式，或者多模终端在 人工设置下直接进入机会频语接入通信模式。
相互通信的两个多模终端，可以分别各自向授权频段网络请求分配授权频 段资源用于机会频语接入，也可以单独的由其中的一个多模终端向授权频段网 络请求授权频段资源， 此时， 该多模终端需要将标明使用授权频段资源的所有 多模终端的用户识别码的信息，如各个多模终端的介质访问控制（ MAC, Media Access Control ) 地址或各个多模终端的国际移动用户识别码 （ IMSI , International Mobile Subscriber Identification Number ), 发送给授权频段网 络。
另一种可选的方案是， 在 101 之前， 第一多模终端向用户数据中心签约 机会频语接入业务，表示第一多模终端申请开通了机会频语接入使用功能，基 站在向第一多模终端分配授权频段资源之前会向用户数据中心查询第一多模 终端是否开通了机会频语接入使用功能，若第一多模终端没有向用户数据中心 签约该机会频 "普接入业务， 第一多模终端将被拒绝分配授权频段空闲资源和 / 或基站预置的专用于以机会频语接入方式使用的授权频段资源 ,以避免授权频 段资源被随意占用， 影响授权频段通信网络的通信。 此时， 第一多模终端和第 二多模终端交互的能力进一步包括：是否获得了用户数据中心的机会频语接入 的许可。 在实际应用中， 用户数据中心具体可以为： 归属位置寄存器（HLR, Home Location Register )或拜访位置寄存器 ( VLR, Visitor Location Register ) 或移动管理实体（MME, Mobility Management Entity )等。
在本发明实施例中，第一多模终端从授权频段网络中获得可以以机会频谱 接入方式使用的授权频段资源时， 可以采用如下方式：
第一多模终端接收授权频段网络内的基站通知的授权频段空闲资源和 /或 基站预置的专用于以机会频语接入方式使用的授权频段资源。授权频段网络内 的基站在具体实现时， 可以广播授权频段的空闲资源和 /或专用于以机会频谱 接入方式使用的授权频段资源，以供有机会频语接入需要的多模终端在需要时 检测，其中专用于以机会频语接入方式使用的授权频段资源为基站从所有的授 权频段中预置的一段时间内的部分或者全部特定的授权频段，该预置的资源专 门用于机会频语接入使用。
第一多模终端在具体实现时，可以采用与授权频段协议标准相兼容的协议 格式，在授权频段上接收授权频段网络内的基站发送的授权频段空闲资源信息 或者授权频段上的机会频语接入资源信息。
在本发明实施例中，第一多模终端从授权频段网络中获得可以以机会频谱 接入方式使用的授权频段资源时， 还可以采用如下方式：
首先， 第一多模终端向授权频段网络内的基站请求授权频段空闲资源和 / 或基站预置的专用于以机会频语接入方式使用的授权频段资源， 然后， 第一多 模终端接收授权频段网络内的基站通知的授权频段空闲资源和 /或基站预置的 专用于以机会频语接入方式使用的授权频段资源。授权频段网络内的基站在具 体实现时， 可以广播授权频段的空闲资源和 /或专用于以机会频语接入方式使 用的授权频段资源， 以供有机会频语接入需要的多模终端在需要时检测， 其中 专用于以机会频语接入方式使用的授权频段资源为基站从所有的授权频段中 预置的一段时间内的部分或者全部特定的授权频段，该预置的资源专门用于机 会频谱接入使用。
在具体实现时， 第一多模终端采用授权频段协议标准相兼容的协议格式， 在授权频段上向授权频段网络内的基站发送授权频段空闲资源请求信息，基站 根据该请求信息为第一多模终端分配授权频段资源，并将分配的授权频段资源 发送给第一多模终端。
102、 第一多模终端采用非授权频段协议标准在授权频段资源上与第二多 模终端通信。
在本发明实施例中， 第一多模终端从授权网络中得到授权频段资源后， 第 一多模终端采用非授权频段协议标准在授权频段资源上向第二多模终端发送 通信数据，采用非授权频段协议标准在授权频段资源上接收第二多模终端发送 的通信数据， 实现第一多模终端和第二多模终端的通信， 本发明实施例中的第 二多模终端和操作 101 中描述的第一多模终端可以是相同类型的终端， 例如 可以同时集成有多个通信协议标准，一类是支持授权频段通信协议标准， 另一 类是支持非授权频段通信协议标准。在实际应用中， 可以在第二多模终端内部 设置授权频段通信模块和非授权频段通信模块，用于实现以机会频语接入方法 使用授权频段资源。第二多模终端也可以是基带仅支持非授权频段通信协议标 准， 但射频支持授权频段和非授权频段的终端或者接入点 （ Access Point )。
需要说明的是，在本发明实施例中， 第一多模终端在结束与第二多模终端 通信后， 或者第一多模终端在确定退出机会频语接入模式后， 可选的一种方案 是， 第一多模终端向授权频段网络发送通知消息，通知消息用于表示第一多模 终端退出机会频语接入通信模式，以使授权频段网络停止分配授权频段资源给 第一多模终端，或者触发授权频段网络记录第一多模终端以机会频语接入方式 使用授权频段资源的时间信息和 /或授权频段资源的大小信息。
在本发明实施例中，由第一多模终端从授权频段网络获取可以以机会频谱 接入方式使用的授权频段资源，然后采用非授权频段协议标准在授权频段资源 上实现与第二多模终端的通信， 可以实现非授权频段标准的通信，提高授权频 段的利用率。由于第一多模终端使用的授权频段资源是由授权频段网络所分配 的， 用于实现机会频语接入， 而不是由非授权用户自主决定， 故可以避免非授 权用户对授权用户的干扰。 同时，在机会频语接入的授权频段上承载的是非授 权频段的通信协议标准， 而不需要再开发新的机会频语接入通信协议标准，避 免了承载新的通信协议标准所带来的终端实现复杂度。
上一实施例从多模终端的角度描述了本发明实施例提供的通信方法，接下 来介绍从基站的角度描述的本发明实施例提供的通信方法，如图 2所示，包括： 201、 基站为第一多模终端分配第一多模终端以机会频语接入方式使用的 授权频段资源。
在本发明实施例中，基站为第一多模终端分配第一多模终端以机会频语接 入方式使用的授权频段资源， 在实际应用中， 基站在进行资源调度的时候， 可 以将满足授权用户业务之外的空闲资源分配给第一多模终端，以便第一多模终 端以机会频语接入方式使用授权频段资源；或者基站将对授权用户通信干扰较 低的一段授权频段资源分配给第一多模终端，使第一多模终端以机会频语接入 方式使用授权频段资源 ,即授权用户和机会频语接入用户共享一段授权频段资 源。
在本发明实施例的一种实际应用中，基站可以定期或者不定期的广播授权 频段空闲资源或者专用于以机会频语接入方式使用的授权频段资源，任意多模 终端可以以机会频语接入的方式使用这些授权资源，而不是基站特意为某个特 定的多模终端所分配。
在本发明实施例的另一种实际应用中，第一多模终端向基站发送授权频段 空闲资源请求或者专用于以机会频语接入方式使用的授权频段资源请求，基站 接收到上述请求后，基站为第一多模终端分配授权频段空闲资源或者基站预置 的专用于以机会频语接入方式使用的授权频段资源。
在实际应用中，如果基站没有满足授权用户业务之外的空闲资源， 或者没 有对授权用户通信干扰较低的授权频段资源分配给第一多模终端 ,则基站拒绝 为第一多模终端分配第一多模终端以机会频语接入方式使用的授权频段资源。
需要说明的是，在本发明实施例中， 当第一多模终端向用户数据中心签约 机会频语接入业务的场景下， 另一种可选的实现方式是，基站接收第一多模终 端发送的授权频段空闲资源请求和 /或专用于以机会频语接入方式使用的授权 频段资源请求之后 ,基站从用户数据中心获取第一多模终端的机会频语接入许 可状态，若机会频语接入许可状态为第一多模终端没有向用户数据中心签约机 会频语接入业务， 基站拒绝第一多模终端的授权频段空闲资源请求和 /或专用 于以机会频语接入方式使用的授权频段资源请求，若机会频语接入许可状态为 第一多模终端已经向用户数据中心签约机会频语接入业务，基站发起向第一多 模终端通知授权频段资源的操作。 在实际应用中， 用户数据中心具体可以为： 归属位置寄存器或移动管理实体等。
在实际应用中， 基站向第一多模终端分配的授权频段资源可以为多种形 式， 分别可以是动态配置的授权频段资源， 或半静态配置的授权频段资源， 或 周期配置的授权频段资源， 或通过一次触发配置的授权频段资源， 以下将将作 出伴细介绍， 例: ¾口：
动态配置的授权频段资源，该动态配置的授权频段资源可以以比较快的速 度更新， 如在 LTE网络中， 所分配的授权频段资源可以每 1毫秒（ms )更新 一次， 动态配置的授权频段资源可以通过物理层信令承载， 如在 LTE通信协 议中的物理下行控制 PDCCH信道。
半静态配置的授权频段资源，该半静态配置的授权频段资源资源可以以较 慢的速度更新， 例如 5ms 以上， 半静态配置的授权频段资源可以通过媒介访 问控制（ MAC )层信令或者无线资源控制协议（ RRC, Radio Resource Control ) 信令配置。
周期配置的授权频段资源，该周期配置的授权频段资源可以以一定的周期 变化， 例如， 基站可以将每个子帧的第 100 ~ 110个资源块（RB, Resource Block )分配为可以以机会频 "普接入方式使用的授权频段资源， 或者基站可以 将每 4ms中的第 2个 ms的全部 RB分配为可以以机会频语接入方式使用的 授权频段资源， 或者基站可以将每 4ms的第 2个 ms的第 90 ~ 100个 RB分 配为可以以机会频语接入方式使用的授权频段资源等。
通过一次触发配置的授权频段资源，是可以以仅在一个有限的预先定义的 时间内有效， 例如仅仅是 4ms 内有效， 此后不可以继续使用该授权频段资源 等。
在实际应用中，基站向第一多模终端分配授权频段资源可以是连续的或非 连续的。 即， 基站所分配的授权频段资源可以是连续的一段频谱， 或者是非连 续的一段频谱。
在实际应用中，基站向第一多模终端分配授权频段资源可以是一段时间内 的全部或者部分授权频段频谱资源。
202、 基站向第一多模终端发送该第一多模终端以机会频语接入方式使用 的授权频段资源信息。
基站在分配授权频段资源给第一多模终端后 ,将该资源的信息发送给第一 终端， 以便第一终端利用该授权频段资源与第二多模终端进行通信。
需要说明的是，授权频段资源信息用于说明基站为第一多模终端分配的授 权频段资源，第一多模终端在接收到该授权频段资源信息之后可以获取到基站 分配的授权频段资源。
在本发明实施例中，基站向第一多模终端发送第一多模终端可以以非授权 频段协议标准使用的授权频段资源信息，在实际应用中， 第一多模终端可以内 部设置授权频段通信模块和非授权频段通信模块，基站可以向第一多模终端的 授权频段通信模块发送授权频段资源，由第一多模终端的授权频段通信模块再 将基站分配的授权频段资源发送给第一多模终端的非授权频段通信模块，实现 由第一多模终端的非授权频段通信模块使用授权频段资源进行的通信的功能。
需要说明的是，在具体实现时可以由基站通过物理层信令或高层信令向第 一多模终端发送授权频段资源信息。例如： 当第一多模终端支持的授权频段通 信协议为 LTE 协议， 基站使用的物理层信令可以为物理下行控制信道 ( PDCCH , Physical Downlink Control Channel )信令， 其中 PDCCH信令 承载可以以机会频语接入方式使用的授权频段资源信息。基站使用的高层信令 可以为高层的无线资源控制协议（RRC )链接建立信令， 该信令承载可以以 机会频语接入方式使用的授权频段资源信息； 或者高层信令可为 RRC的配置 信令、 RRC的重配置信令、 或者 RRC的链接重建立信令等， 此处仅作说明， 不作限定。
在实际应用中，基站向第一多模终端发送授权频段资源信息可以存在多种 实现方式， 例如：
基站以单播的方式向第一多模终端通知第一多模终端以机会频语接入方 式使用的授权频段资源信息， 其中， 单播指的是只有特定的终端（在本发明实 施例中具体是指第一多模终端）可以接收到该信令。 例如， 可采用经过特殊无 线网络临时鉴定（ RNTI , Radio Network Temporary Identity )加扰的 PDCCH 传输可以以机会频谱接入方式使用的授权频段资源， 只通知经过许可的终端 (第一多模终端）该 RNTI是多少， 则只有经过许可的第一多模终端可以获得 以机会频语接入方式使用的授权频段资源。为了避免非经许可的其它终端使用 该授权频段资源 ,基站进一步的可以将用于传输机会频语接入方式使用的授权 频段资源的 RNTI定期更新或不定期更新， 每次更新， 基站仅通知经过许可的 第一多模终端 RNTI的值是多少。
或，基站以广播的方式向所有网络设备服务下的终端发送信令， 该信令包 括授权频段资源信息， 其中， 广播是指所有的网络设备服务的终端都可以接收 到该信令。
或，基站以组播的方式向第一多模终端通知第一多模终端以机会频 "普接入 方式使用的授权频段资源信息， 其中，组播是指所有请求机会频语接入的一个 或多个终端组成一个或者多个机会频语接入终端组， 所有组内的用户（包括本 发明实施实例中的第一多模终端）都可以接收到该信令。
需要说明的是，在本发明实施例中， 当第一多模终端退出机会频语接入通 信模式后， 例如第一多模终端结束与第二多模终端的通信后， 第一多模终端还 可以向基站发送通知消息，通知消息用于表示第一多模终端退出机会频普接入 通信模式， 基站接收该通知消息后， 停止分配授权频段资源给第一多模终端， 以空闲出频段可以用于向其他的多模终端分配， 提高网络的利用率。
另一种可选的方案是，基站接收该通知消息后，基站记录第一多模终端使 用授权频段资源的时间信息和 /或授权频段资源的大小信息， 基站进一步的将 第一多模终端使用授权频段资源的时间信息和 /或授权频段资源的大小信息发 送到用户数据中心， 以使用户数据中心实现对第一多模终端的计费。
另一种可选的方案是， 若第一多模终端发生切换，基站将第一多模终端以 机会频语接入方式工作的信息发送给目标基站，以使目标基站为第一多模终端 分配第一多模终端以机会频语接入方式使用的授权频段资源。
在本发明实施例中，由基站为第一多模终端分配可以以机会频语接入方式 使用的授权频段资源，然后基站向第一多模终端发送第一多模终端以机会频谱 接入方式使用的授权频段资源信息，用于实现第一多模终端采用非授权频段协 议标准在授权频段资源上与第二多模终端的通信，可以实现基于非授权频段标 准的通信，提高授权频段的利用率。 由于第一多模终端使用的授权频段资源是 由基站向第一多模终端所分配的， 而不是由非授权用户自主决定，故可以避免 非授权用户对授权用户的干扰。
以上实施例分别介绍了本发明实施例提供的通信方法，接下来介绍本发明 实施例提供的使用该通信方法的通信设备， 如多模终端、 基站和通信系统。
如图 3 所示， 本发明实施例提供的多模终端 300, 这里也称该多模终端 300为第一多模终端， 包括：
授权频段资源获取单元 301，用于从授权频段网络获取可以以机会频语接 入方式使用的授权频段资源；
非授权频段协议标准通信单元 302,用于采用非授权频段协议标准在授权 频段资源上与第二多模终端通信。
在本发明实施例中， 多模终端 300 同时集成有授权频段通信协议标准和 非授权频段通信协议标准， 本发明实施例中的多模终端 300具体可以支持其 中的一个或多个授权频段通信协议标准。授权频段网络 于授权频段协议标 准的。该授权频段网络可以包括无线接入网中的服务节点，授权频段网络掌握 其授权频段资源的使用权。 本发明实施例中的多模终端 300具体可以支持其 中的一个或多个非授权频段通信协议标准。
授权频段资源获取单元 301 可以是个处理器， 具体可以是授权频段通信 单元， 例如 LTE基带处理单元。 非授权频段协议标准通信单元 302可以是另 一处理器， 例如 WIFI处理单元。
在实际应用中， 一种可选的实现方式是， 多模终端 300还可以包括： 机会频语接入签约单元 303,用于向用户数据中心签约机会频语接入业务 并触发授权频段资源获取单元 301执行。 多模终端 300向用户数据中心签约 机会频语接入业务， 表示多模终端 300 申请开通了机会频语接入使用功能， 基站在向多模终端 300分配授权频段资源之前会向用户数据中心查询多模终 端 300是否开通了机会频语接入使用功能， 若多模终端 300没有向用户数据 中心签约该机会频语接入业务， 多模终端 300将被拒绝分配授权频段空闲资 源和 /或基站预置的专用于以机会频语接入方式使用的授权频段资源， 以避免 授权频段资源被随意占用， 影响授权频段通信网络的通信。
在本发明实施例中， 在实际应用中， 一种可选的实现方式是， 多模终端 300还可以包括：
机会频语接入协商单元 304,用于与第二多模终端协商进入机会频语接入 通信模式。 在实际应用中， 多模终端 300和第二多模终端的首选工作频段都 是非授权频段， 在多模终端 300发现非授权频段比较拥挤时， 需要通信的双 方就可以相互协商进行机会频语接入通信模式，或者多模终端在人工设置下直 接进入机会频谱接入通信模式。
在实际应用中， 授权频段资源获取单元 301可以包括：
机会频普接入资源请求模块 3011 , 用于向授权频段网络内的基站请求授 权频段空闲资源和 /或专用于以机会频语接入方式使用的授权频段资源；
授权频段资源接收模块 3012, 用于接收授权频段网络内的基站通知的授 权频段空闲资源和 /或基站预置的专用于以机会频语接入方式使用的授权频段 资源。
在实际应用中， 另一种实现方式是， 授权频段资源获取单元 301 可以包 括：授权频段资源接收模块 3012,而不包括机会频语接入资源请求模块 3011。 其中， 授权频段资源接收模块 3012, 用于接收授权频段网络内的基站通知的 授权频段空闲资源或者基站预置的专用于以机会频谱接入方式使用的授权频 段资源。 此时， 多模终端 300 中不存在机会频语接入资源请求模块， 多模终 端 300 不需要向基站请求授权频段资源， 而基站可以直接将授权频段资源发 送给多模终端 300。
在本发明实施例中， 在实际应用中， 一种可选的实现方式是， 多模终端
300还可以包括：
通知消息发送单元 305, 用于向授权频段网络发送通知消息， 其中， 通知 消息用于表示该第一多模终端 300 退出机会频语接入通信模式， 以使授权频 段网络停止分配授权频段资源给第一多模终端 300或者触发授权频段网络记 录第一多模终端 300以机会频语接入方式使用授权频段资源的时间信息和 /或 授权频段资源的大小信息。
以上实施例只介绍了各单元模块之间的结构关系，在实际应用中，各单元 模块的执行方法请参阅图 1所示的方法， 此处不再贅述。
在本发明实施例中， 由授权频段资源获取单元 301 从授权频段网络获取 可以以机会频语接入方式使用的授权频段资源 ,然后非授权频段协议标准通信 单元 302 采用非授权频段协议标准在授权频段资源上实现与第二多模终端的 通信， 可以实现基于非授权频段标准的通信， 提高授权频段的利用率。 由于第 一多模终端使用的授权频段资源是由授权频段网络所分配并用于实现机会频 谱接入， 而不是由非授权用户自主决定，故可以避免非授权用户对授权用户的 干扰。
在一个具体的应用场景下， 如图 4 所示， 本发明实施例的一种多模终端 400, 这里也称该多模终端 400为第一多模终端， 该多模终端包括： 授权频段 资源获取单元 401 包括： 第一接收模块 4011、 第一发送模块 4012和第一机 会频谱接入控制模块 4013, 非授权频段协议标准通信单元 402包括： 第二接 收模块 4021、 第二发送模块 4022和第二机会频语接入控制模块 4023。 授权 频段资源获取单元 401可以是处理器， 如 LTE基带处理器。 非授权频段协议 标准通信单元 402可以是处理器， 如 WIFI处理器。 第一机会频语接入控制模 块 4013和第二机会频语接入控制模块 4023用于实现对机会频语接入的控制 和调度。
其中， 授权频段资源获取单元 401 能够实现遵循授权频段的通信协议标 准的通信功能， 第一接收模块 4011和第一发送模块 4012分别用于实现信号 的接收和发送功能。 授权频段资源获取单元 401 能够从授权频段资源控制器 (如基站）获得可以以机会频语接入方式使用的授权频段资源信息（时间、 频 率等）。 第一机会频语接入控制模块 4013, 可以是处理器， 用来判断是否启动 机会频 "普接入模式， 第一机会频语接入控制模块 4013的判断准则可以是， 如 接收到来自用户的手动指令要求， 或者检测到网络拥塞， 开始启动机会频语接 入模式。 在开始启动机会接入频谱模式后， 第一机会频谱接入控制模块 4013 控制第一接收模块 4011从授权频段网络获得可以用于机会频语接入通信的资 源， 第一机会频语接入控制模块 4013控制第一发送模块 4012将授权频段资 源发送给非授权频段协议标准通信单元 402。 第一机会频谱接入控制模块 4013进一步会在确定启动机会频语接入通信模式后， 还可以控制第一接收模 块 4011接收非授权频段协议标准通信单元 402发送的授权频段空闲资源请求 和 /或专用于以机会频语接入方式使用的授权频段资源请求， 第一机会频语接 入控制模块 4013控制第一发送模块 4012向授权频段网络发送请求信号， 请 求授权频段网络分配授权频段空闲资源和 /或专用于以机会频语接入方式使用 的授权频段资源。
非授权频段协议标准通信单元 402 能够实现遵循非授权频段的通信协议 标准的通信功能， 第二接收模块 4021和第二发送模块 4022用于实现信号的 接收和发送功能。 进一步包括， 非授权频段协议标准通信单元 402 能够在授 权频段上进行信号的接收和发送。 第二机会频语接入控制模块 4023可以是处 理器，用来判断是否启动机会频语接入模式，第二机会频语接入控制模块 4023 的判断准则可以是，如接收到来自用户的手动指令要求，或者检测到网络拥塞， 开始启动机会频语接入模式。在开始启动机会接入频语模式后， 第二机会频谱 接入控制模块 4023控制第二接收模块 4021从授权频段资源获取单元 401获 得可以用于机会频语接入通信的资源， 第二机会频语接入控制模块 4023控制 第二发送模块 4022向第二多模终端发送通信数据， 第二机会频语接入控制模 块 4023控制第二接收模块 4021接收第二多模终端发送的通信数据。 第二机 会频语接入控制模块 4023会在确定启动机会频语接入通信模式后， 还可以控 制第二发送模块 4022向授权频段资源获取单元 401发送授权频段空闲资源请 求和 /或专用于以机会频语接入方式使用的授权频段资源请求。
在一种硬件的布局下， 授权频段资源获取单元 401 , 包括授权频段接收数 字处理模块、模数转换器、授权频段接收射频通道、授权频段发送数字处理模 块、 数摸转换器、 授权频段发送射频通道、 授权频段天线模块。 非授权频段协 议标准通信单元 402 , 包括非授权频段接收数字处理模块、 模数转换器、 非授 权频段接收射频通道、 非授权频段发送数字处理模块、 数摸转换器、 非授权频 段发送射频通道、 非授权频段天线模块。 授权频段资源获取单元 401 和非授 权频段协议标准通信单元 402通过上述硬件布局实现基带信号的处理功能。 可选的是，授权频段天线模块和非授权频段天线模块进一步可以共用。授权频 段和非授权频段模块的模数转换器和数模转换器进一步可以共用。 进一步的 , 机会频谱接入模式下， 第一机会频谱接入控制模块 4013和第二机会频谱接入 控制模块 4023控制非授权频段接收数字处理模块与授权频段接收射频通道相 连，非授权频段发送数字处理模块与授权频段发送射频通道相连，如图 5所示。 可以看到，非授权频段发送数字处理模块可通过开关连接至授权频段发送射频 通道与非授权频段发送射频通道中的任一个，从而实现在不同发射通道间的切 换。 当非授权频段发送数字处理模块连接至授权频段发送射频通道时， 其采用 授权频段进行基于非授权频段协议标准的通信。
在机会接入频谱模式下，授权频段接收射频通道和授权频段发送射频通道 可以被非授权频段通信协议接收 (发送 )数字处理模块独占， 并用于处理通信 数据， 即此时多模终端与授权频段网络无通信信号， 或者来自非授权频段通信 协议接收（发送）数字处理模块的信号可以与来自授权频段通信协议接收（发 送）处理模块的信号一起共用授权频段射频通道。非授权频段通信协议接收（发 送 )数字处理模块究竟是否与授权频段通信协议接收 (发送 )数字处理模块共 用一个射频通道， 可以通过开关选择来实现。 其中， 前者的一种实现方式如图 6所示，第一机会频语接入控制模块 4013和第二机会频语接入控制模块 4023 通过开关控制授权频道接收（发送）射频通道是与非授权频段通信协议接收（发 送 )数字处理模块的信号相连还是与授权频段通信协议接收 (发送 )数字处理 模块的信号相连。后者的一种实现方式如图 7所示，在接收通道可以增加一个 分路器将两路信号分开，在发射通道可以增加一个合路器将两路信号合并， 第 一机会频语接入控制模块 4013和第二机会频语接入控制模块 4023通过开关 控制非授权频段通信协议接收 (发送 )数字处理模块的信号与授权频段射频通 道或者非授权频段射频通道相连， 图 7为非授权频段通信协议接收 (发送 )数 字处理模块的信号和授权频段通信协议接收 (发送 )数字处理模块的信号通过 合路器或分路器共用授权频段射频通道的示意图。
