Description

一种短距离通信的方法、 设备和系统 技术领域
本发明涉及通信领域, 尤其涉及一种短距离通信的方法、 设备 和系统。
背景技术
短距离通信泛指在较小的区域内 (数百米) 提供通信的技术, 目前常见的技术大致有无线短距离通信,如 IEEE 802. 1 1 系列 WLAN ( Wireless Local Area Networks ; 无线局 i或网 )、 IEEE802. 15 系列
WPAN ( Wireless Personal Area Network , 无线个域网 )、 HomeRF ( Home Radio Frequency , 家庭无线电频率) 和红外传输技术等, 此 外还有有线形式的通信技术, 如以太网 Ethernet 等。 对于有线通信 技术, 其通信距离可以很长, 未必是短距离通信, 在本方法中, 统 一称为短距离通信, 不再贅述。
在单网络节点且多用户之间的协作通信的场景, 或者称为
MUCC ( Multiple UEs Cooperative Communication , 多用户协作通信 ) 的场景下, 当至少两个 UE 之间进行短距离通信时, 为了增加可靠 性和吞吐率, 这些 UE可以建立一种 MUCC的关系, 比如, 至少两 个 UE中的一个 UE需要发送或接收数据, 除该一个 UE之外的其他 UE可协助该一个 UE进行通信。这里,将该一个 UE命名为受益 UE , 将除该一个 UE之外的其他 UE命名为支撑 UE; 则该支撑 UE为用 于数据的承载与传输的 UE , 该受益 UE为数据的发送方或者最终的 接收方和使用方。
对于下行数据来说, 网络可以将下行数据分别发送给支撑 UE , 支撑 UE将数据通过短距离通信 (例如 WiFi )发送给受益 UE , 完成 UE之间的协作通信, 受益 UE最后合并数据。 同理, 上行数据也可 以通过自身或者其他支撑 UE 发送至网络, 然后网络进行数据的合 并, 完成 UE之间的协作通信。 但是, 绝大部分短距离通信技术, 都是提供节点之间的连接, 基本不进行 QoS ( Quality of Service , 服务质量) 的区分, 更没有承 载的概念, 而蜂窝网络设立无线承载就是用来区分不同的 QoS , 当 进行多用户协作通信时, 对于上下行数据, 支撑 UE或受益 UE是无 法在短距离链路上区分出数据对应哪个无线承载的, 从而无法进一 步处理数据, 也就无法区分不同的 QoS。

具体实施方式
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, 所描述的实施例仅仅是本发明 一部分实施例, 而不是全部的实施例。 基于本发明中的实施例, 本 领域普通技术人员在没有作出创造性劳动前提下所获得的所有其他 实施例, 都属于本发明保护的范围。
智能手机基本都能同 时支持短距离通信技术 ( 如 WiFi 或 BlueTooth , LTE-D2D等 ) 和蜂窝通信技术 (如 LTE, 3G UMTS或 CDMA, 2G GSM, WiMAX等), 以蜂窝技术为 SAE/LTE , 短距离通 信技术为 WiFi 为例, 在单网络节点且多用户之间的协作通信的场 景 , 或 者 称 为 多 用 户 协作 通信 ( multiple UEs cooperative communication , 简称 MUCC ) 的场景下, 当至少两个 UE ( User Equipment , 终端) 都具有同时支持 WiFi和 LTE的特点 , 为了增加 可靠性和吞吐率,该至少两个 UE之间可以建立一种 MUCC的关系 , 即至少两个 UE中的一个 UE需要发送或接收数据, 除该一个 UE之 外的其他 UE可进行协助, 协助该一个 UE进行通信; 具体地, 网络 可以 居该其它 UE上 的配对信息建立该一个 UE与该其它 UE之 间的配对关系; 或者, 网络自行选择该一个 UE附近的该其它 UE , 并建立该一个 UE与附近的其它 UE之间的配对关系。 本发明中, 将 该一个 UE命名为被协助 UE、 被服务 UE或者受益 UE , 将除该一个 UE之外的其他 UE命名为协助 UE、 服务 UE或支撑 UE , 上述 UE 的命名只是本发明举的一个例子, 本发明中 UE 的命名包括并不限 于上述命名的举例。
以支撑 UE与受益 UE为例, 受益 UE为上行数据最终的发送方 或者为下行数据的最终接收方 (从蜂窝角度来看)。 针对某一 RB来 说, 一般只有一个, 而支撑 UE是用来协助受益 UE而进行数据中转 的 UE。 针对受益 UE的某一 RB来说, 可以有多个。
以支撑 UE与受益 UE为例, 受益 UE和支撑 UE的概念是从受 益 UE的 RB角度来看的, 一个受益 UE可以有一个支撑 UE , 例如, UE 1和 UE2组成 MUCC , 它们可以相互协助通信, 这样, 站在 UE 1 的一个 RB 角度, UE2可以支撑 UE 1 的该一个 RB , 于是 UE 1是受 益 UE , UE2是支撑 UE。 而与此同时, UE 1也可以支撑 UE2的一个 RB , 于是站在 UE2 中该一个 RB 的角度, UE2是受益 UE , 而 UE 1 是支撑 UE。 一个 UE也可以有多个支撑 UE , 例如 UE3也可以支撑 UE2 中的该一个 RB , 这样 UE2 中该一个 RB有 UE 1和 UE3 两个支 撑 UE。
以支撑 UE与受益 UE为例, 当上述 UE处于相同的短距离连接 范围内,网络可以将下行数据分别发送给上述支撑 UE和受益 UE(— 种优化的方法是, 网络调度总会选择当时无线链路情况最好的一个 UE 发送), 当网络将下行数据发送给支撑 UE 时, 接收到数据的支 撑 UE再将数据通过短距离通信 (例如 WiFi ) 或者有线网 (如果受 益 UE与支撑 UE之间有有线连接) 发送给受益 UE。 当然, 数据也 可以是直接到达受益 UE (如该受益 UE 在某调度时机无线链路最 好), 由受益 UE进行数据的合并。 同理, 受益 UE的上行数据也可 以通过受益 UE 自身或者其他支撑 UE发给网络, 然后网络进行数据 的合并, 完成 UE之间的协作通信。
对于下行数据来说, 网络可以将下行数据分别发送给支撑 UE , 支撑 UE将数据通过短距离通信 (例如 WiFi )发送给受益 UE , 完成 UE之间的协作通信, 受益 UE最后合并数据。 同理, 上行数据也可 以通过自身或者其他支撑 UE 发送至网络, 然后网络进行数据的合 并, 完成 UE之间的协作通信。
通过支撑 UE的协助传输,可以增加受益 UE通信的可靠性和吞 吐率。
本发明实施例提供一种短距离通信的方法, 如图 1 所示, 本发 明实施例的执行主体为受益 UE , 该方法包括:
5101、 受益 UE建立短距离承载和第一无线承载的映射。
其中, 该第一无线承载为该受益 UE 的受益无线承载; 该短距 离承载为协助支撑 UE进行与该受益 UE之间通信而建立的承载; 该 短距离承载在该支撑 UE 侧与第二无线承载映射; 该第二无线承载 为该支撑 UE 协助该第一无线承载而建立的无线承载, 该第一无线 承载在基站侧与该第二无线承载映射。
需要说明的是, 上述短距离承载在该支撑 UE 侧与第二无线承 载映射可以是由支撑 UE建立的, 具体地, 支撑 UE接收基站发送的 第二重配消息, 并根据该第二重配消息建立短距离承载与第二无线 承载映射。
5102、 该受益 UE 通过该第一无线承载和短距离承载的映射进 行数据的接收与发送。
可选地, 该受益 UE 在建立短距离承载和第一无线承载的映射 前, 还可以建立第一无线承载, 该第一无线承载的建立以及短距离 承载和第一无线承载的映射的建立包括以下两种方式:
方式一: 该受益 UE 接收基站发送的第一重配消息, 并根据该 第一重配消息建立该第一无线承载; 该受益 UE 根据该第一重配消 息建立短距离承载和第一无线承载的映射。
方式二, 该受益 UE 接收基站发送的承载建立消息, 并根据该 承载建立消息建立该第一无线承载; 该受益 UE 接收基站发送的第 一重配消息, 并根据该第一重配消息建立短距离承载和第一无线承 载的映射。
上述方式一和方式二的区别在于, 方式一中, 受益 UE 根据基 站发送的第一重配消息就完成第一无线承载的建立以及短距离承载 和第一无线承载的映射的建立; 而方式二中, 受益 UE 通过从基站 接收的承载建立消息建立该第一无线承载, 并通过从基站接收的第 一重配消息建立短距离承载和第一无线承载的映射的建立。 也就是 说, 方式一中是通过一条消息就完成第一承载的建立以及短距离承 载和第一无线承载的映射的建立, 方式二中是通过两条消息分别完 成第一承载的建立以及短距离承载和第一无线承载的映射的建立。
可选地, 该受益 UE 根据该第一重配消息中的第一短距离承载 配置信息建立该短距离承载。
具体地, 该第一短距离承载配置信息包括支撑 UE 的短距离信 息 (如频点)。
需要说明的是, 该短距离承载的建立还可以是支撑 UE 在接收 到基站发送的第二重配消息后, 根据该第二重配消息中的第二短距 离承载配置信息建立该短距离承载。 其中, 该第二短距离承载配置 信息包括受益 UE的短距离信息 (如频点), 当然, 该受益 UE也可 以自行建立该短距离承载。
另夕卜,通过基站控制受益 UE或支撑 UE建立短距离承载具体包 括以下两种情况:
情况一: 受益 UE 发起业务时, 第一无线承载还未建立的, 此 时, 短距离承载的建立是在该受益 UE 根据第一重配消息建立第一 无线承载的同时建立的;
情况二, 受益 UE 发起业务时, 第一无线承载已建立, 此时, 受益 U E发起的业务需要根据第一重配消息重新配置第一无线承载, 则该短距离承载的建立是在重新配置该第一无线承载时建立的。
可选地, 该受益 UE 获取基站配置的第一短距离承载标识和第 一无线 7|载标识。
其中, 该第一短距离承载标识在该受益 UE 侧与该短距离承载 对应; 该第一无线承载标识与该第一无线承载对应。
则该受益 UE 通过第一短距离承载标识和第一无线承载标识的 映射建立短距离承载和第一无线承载的映射。
进一步地, 该受益 UE 将该第一短距离承载标识发送至该支撑 UE , 以使得该支撑 UE在向该受益 UE发送数据时, 在该数据中携 带该第一短距离承载标识。
具体地, 当支撑 UE向受益 UE发送数据时, 数据中可携带第一 短距离承载标识, 使得受益 UE 能够根据该第一短距离承载标识识 别数据对应的短距离承载, 从而进行处理。
可选地, 该受益 UE建立短距离承载和第一无线子承载的映射。 其中, 该第一无线子承载为在该第一无线承载中与该第二无线 7|载一一对应的承载。
进一步地, 在该受益 UE 建立短距离承载和第一无线子承载的 映射前, 该受益 UE 建立第一无线子承载, 该第一无线子承载的个 数与该支撑 UE的个数相同。
可选地, 该受益 UE 向基站发送第二连接请求消息, 以便该基 站根据该第二连接请求消息中的第二受益承载信息配置第二无线承 载。
其中, 该第二受益承载信息包括: 该支撑 UE 的标识, 该第一 无线承载标识、 该第一短距离承载标识和 /或第二短距离承载标识, 该第二短距离承载标识为该短距离承载在该支撑 U E侧对应的标识。
需要说明的是, 上述第二无线承载的配置也可以是支撑 UE 向 基站发送第一连接请求消息, 以便该基站根据该第一连接请求消息 中的第一受益承载信息对应配置第二无线承载。
其中, 该第一受益承载信息包括: 该受益 UE 的标识、 该第一 无线承载标识 (或第一无线子承载标识)、 该第一短距离承载标识和 /或该第二短距离承载标识。
进一步地, 在符合预设条件时, 该受益 UE或者支撑 UE向基站 发送译放请求消息, 并在该基站接收到该译放请求消息后, 该支撑 UE接收该基站发送的释放消息; 或者,
该受益 UE 向基站发送释放请求消息, 并在该基站接收到该释 放请求消息后, 该支撑 UE和受益 UE接收该基站发送的释放消息。
例如, 当支撑 UE与受益 UE之间的距离超过一预设距离时, 基 站接收支撑 UE或者受益 UE发送的释放请求消息, 并根据该释放请 求消息向支撑 UE发送释放消息,使得支撑 UE释放对应的第二无线 承载, 和第二无线承载与短距离承载的映射关系。 该预设距离可以 根据实际应用或经验值设置, 基站删除支撑 UE 的第二无线承载和 第二无线承载与第一短距离承载之间的映射; 并且基站删除受益 UE 的第一无线承载与第一短距离承载之间的映射。
具体地, 支撑 UE 会根据该释放消息删除短距离承载, 短距离 承载的删除也会使得第二无线承载删除。 当然, 基站也会发送重配 消息给受益 UE , 使得受益 UE删除第一无线承载或子承载与第一短 距离承载的映射关系。 具体的, 受益 UE与支撑 UE之间的短距离承 载也会被删除。 如果受益 UE与支撑 UE的短距离承载全部被删除, 相应地, 受益 UE与支撑 UE之间的短距离连接也会删除。
又如,当受益 UE取消相应业务导致受益 UE的第一无线承载被 删除时, 基站接收该受益 UE 发送的释放请求消息, 并根据该释放 请求消息向支撑 UE和受益 UE发送释放消息, 基站删除支撑 UE的 第二无线承载和第二无线承载与第一短距离承载之间的映射; 并且 基站删除受益 UE的第一无线承载与第一短距离承载之间的映射。
具体地, 支撑 UE或受益 UE (可根据实际应用 自行配置为支撑 UE或者受益 UE ) 会根据该释放消息删除短距离承载, 短距离承载 的删除也会使得第二无线承载和第一无线子承载删除, 另外, 如果 短距离承载全部被删除, 相应地, 短距离连接也会删除。
下面针对受益 UE和支撑 UE通过第一短距离承载标识区分短距 离承载进行说明:
通过第一短距离承载标识区分短距离承载主要有三种方式: 方式一: 该第一短距离承载标识包含在该受益 UE 的 MAC ( Media Access Control , 介质访问控制层 ) 层或 LLC ( Logical Link Control , 逻辑链路控制 ) 层的 Ether type字段中。
例如, 以 LTE ( Long Term Evolution,长期演进 ) 系统为例, 第 一短距离承载标识的个数最大值不超过 16个, 通常在 8个以下, 因 此, 可以在 Ether type 字段中直接定义第一短距离承载标识 (如 8 个), 来对应不同的短距离承载。
这种方式的好处是避免定义新的协议层。 方式二: 该第一短距离承载标识包含在该受益 UE的 MAC层或 LLC层的 Ether type字段所指示的协议层中。
这里的协议层为新定义的协议层, 通过该 Ether type字段指示 该协议层。
这种方式的好处是时延较低, 对数据的处理效率高; 缺点是对 现有协议的影响较大。
方式三: 该第一短距离承载标识包含在该受益 UE 的网络层或 传输层中的字段所指示的协议层中。
这里的协议层也为新定义的协议层, 该 Ether type字段指示网 络层或传输层字段, 该网络层或传输层字段指示该新定义的协议层。
这种方式主要是将该协议层定义在协议栈的高层之上, 好处是 对现有的协议影响不大, 缺点是时延较高, 对数据的处理效率低且 会依赖高层操作系统。
另外, 若上述 Ether type 字段包含在 MAC 层, 则可以不需要 LLC层。
需要说明的是, 上述各个承载标识的建立在同一个 UE 中不能 重复使用, 但在不同的 UE中可以重复使用。
即当同一个 UE 中对应多个承载时, 各承载对应的承载标识不 同; 但在两个不同 UE中, 这两个不同 UE的 载对应的 载标识可 以相同。
例如, ^^设一个支撑 UE (记为 UE 1 ) 对应两个受益 UE (分别 记为 UE2和 UE3 ) ,且 UE 1 与 UE2之间会建立一个短距离连接; UE 1 与 UE3之间会建立一个短距离连接, 若 UE2 包含两个无线承载(记 为无线承载 1和无线承载 2 ) , UE3 包含一个无线承载 (记为无线承 载 3 ) , UE 1对应 UE2的无线 载 1 的标识建立 UE 1 的无线 载 4 ; 并对应 UE2的无线 7 载 2的标识建立 UE 1 的无线 7 载 5 ; UE 1对应 UE3 的无线承载 3的标识建立 UE 1 的无线承载 6 ; 则 UE 1在与 UE2 的短距离连接上分别建立两个短距离承载并与无线承载 1 和无线承 载 2分别映射, 从而区分 UE 1 中 UE 1 与 UE2之间短距离连接的短 距离承载; 同样地, UE2在与 UE 1 的短距离连接上也分别建立两个 短距离承载分别与无线承载 1和无线承载 2映射, 从而区分 UE2 中 UE 1 与 UE2 之间短距离连接的短距离承载; 另夕卜, UE 1 在与 UE3 的短距离连接上建立短距离承载与无线承载 3的映射, 同样地, UE3 在与 UE 1 的短距离连接上也建立短距离承载与无线承载 3的映射, 这样, 各个承载之间——映射, 使得 UE2和 UE3能够区分数据传输 所对应的无线承载, 这里只是举例说明, 不作限定。
需要说明的是, 上述的映射如受益 UE 的第一无线承载与短距 离承载的映射, 即表示该受益 UE 的第一无线承载 (或第一无线子 承载) 上的数据可以传输到该短距离承载上; 或者, 来自短距离承 载上的数据可以传输到该受益 UE 的第一无线承载 (或第一无线子 承载) 上, 其余各承载之间的映射参考上述受益 UE 的第一无线承 载与短距离承载的映射的说明, 在此就不在贅述了。
另外, 上述的支撑 UE 与受益 UE 之间的短距离连接可以是 WiFi、 蓝牙 ( Blue Tooth ) 或者 Zigbee等短距离通信技术, 甚至还 可以是有线网络如 Ethernet , 此时, 上述受益 UE与支撑 UE之间的 短距离承载为有线连接实现的承载。
承上所述, 本发明实施例主要通过在受益 UE 中建立受益 UE 的第一无线承载 (或第一无线子承载) 与短距离承载之间的映射; 支撑 UE中支撑 UE的第二无线承载与短距离承载之间也存在映射, 同时,在基站中受益 UE的第一无线承载或子承载与支撑 UE的第二 无线承载之间也存在映射。
以下行数据传输为例, 基站根据受益 UE 的第一无线承载 (或 第一无线子承载) 与支撑 UE 的第二无线承载的映射关系, 可以选 择将数据通过第一无线承载直接发送到受益 UE , 或者选择将数据通 过支撑 UE的第二无线承载发送到支撑 UE。
当数据发送到支撑 UE , 该数据中携带第二无线承载标识, 使得 支撑 UE能够识别该数据对应的是第二无线承载, 支撑 UE根据第二 无线承载与短距离承载的映射关系, 将数据通过短距离承载发送至 受益 UE , 数据中携带第一短距离承载标识和 /或第二短距离承载标 识, 受益 UE在通过支撑 UE接收到该数据时, 通过该短距离承载与 第一无线承载 (或第一无线子承载) 的映射将数据发送到该受益 UE 的第一无线承载 (或第一无线子承载) 对应的协议层处理。
上行数据的传输与下行数据传输类似, 受益 UE 可以通过第一 无线承载将上行数据直接发送给基站, 也可以将数据通过第一无线 承载与短距离承载的映射关系, 通过短距离承载发送给支撑 UE , 短 距离承载发送的数据携带第一短距离承载标识和 /或第二短距离承 载标识; 支撑 UE 接收到该数据时, 通过该短距离承载与第二无线 承载的映射, 将数据通过第二无线承载发送到基站; 基站根据支撑 UE的第二无线承载与受益 UE的第一无线承载(或第一无线子承载) 的映射关系, 将数据发送到受益 UE 的第一无线承载 (或第一无线 子承载) 对应的协议层处理。
最终, 通过各承载之间的——映射, 受益 UE 能够根据承载之 间的映射关系区分数据传输对应的无线承载, 从而进一步对数据进 行处理, 区分不同的 QoS。
具体的, 各承载的——映射是通过承载的标识映射来实现的。 如基站发送下行数据给支撑 UE时,会携带支撑 UE的第二无线承载 标识, 使得支撑 UE 能够识别该数据对应的是第二无线承载; 而第 二无线承载与短距离承载对应, 也就是说, 支撑 UE发送给受益 UE 的数据, 要在数据中添加第一短距离承载标识, 使得受益 UE 根据 第一短距离承载标识对应到受益 UE的第一无线承载。 从而受益 UE 会对数据进行对应协议的处理。
进一步地,受益 UE与支撑 UE可自行建立短距离承载并且受益 UE可以 自行建立短距离承载与第一无线承载 (或第一无线子承载) 之间的映射, 这样, 基站只会发送第二重配消息给支撑 UE 来建立 短距离承载与第二无线承载的映射关系。
本发明实施例提供的一种以受益 UE 为执行主体的短距离通信 方法, 第一无线承载和短距离承载存在映射关系, 第二无线承载和 短距离承载存在映射关系, 同时第一无线承载和第二无线承载存在 映射关系, 这样, 各承载之间形成——映射, 从而使得 UE 能够在 短距离链路上区分数据信息传输对应的无线承载以进行相应的处 理。 本发明实施例提供一种短距离通信的方法, 如图 2所示, 本发 明实施例的执行主体为支撑 UE , 该方法包括:
5201、 支撑 UE建立短距离承载和第二无线承载的映射; 其中, 该第二无线承载为该支撑 UE 协助该第一无线承载而建 立的无线承载,该短距离承载为协助该支撑 UE进行与受益 UE之间 通信而建立的承载, 该短距离承载在该受益 UE 侧与第一无线承载 映射, 该第一无线承载为该受益 UE 的受益无线承载; 该第一无线 承载在基站侧与该第二无线承载映射。
需要说明的是, 上述短距离承载在该受益 UE 侧与第一无线承 载映射可以是由筹议 UE建立的, 具体地, 受益 UE接收基站发送的 第一重配消息, 并根据该第一重配消息建立短距离承载与第一无线 承载映射。
5202、 该支撑 UE 通过该第二无线承载和短距离承载的映射进 行数据的接收与发送。
可选地, 在该支撑 UE 建立该短距离承载和第二无线承载的映 射前, 还可以建立第二无线承载, 该第二无线承载的建立以及短距 离承载和第二无线承载的映射的建立包括以下两种方式:
方式一: 该支撑 UE 接收基站发送的第二重配消息, 并根据该 第二重配消息建立第二无线承载; 该支撑 UE 根据该第二重配消息 建立该短距离承载和第二无线承载的映射。
方式二, 该支撑 UE 接收基站发送的承载建立消息, 并根据该 承载建立消息建立该第二无线承载; 该支撑 UE 接收基站发送的第 二重配消息, 并根据该第二重配消息建立短距离承载和第二无线承 载的映射。 上述方式一和方式二的区别在于, 方式一中, 支撑 UE 根据基 站发送的第二重配消息就完成第二无线承载的建立以及短距离承载 和第二无线承载的映射的建立; 而方式二中, 受益 UE 通过从基站 接收的承载建立消息建立该第一无线承载, 并通过从基站接收的第 二重配消息建立短距离承载和第二无线承载的映射的建立。 也就是 说, 方式一中是通过一条消息就完成第二承载的建立以及短距离承 载和第二无线承载的映射的建立, 方式二中是通过两条消息分别完 成第二承载的建立以及短距离承载和第二无线承载的映射的建立。
可选地, 在该支撑 UE 接收基站发送的第二重配消息后, 该支 撑 UE 根据该第二重配消息中的第二短距离承载配置信息建立该短 距离承载。
具体地, 该第二短距离承载配置信息包括支撑 UE 的短距离信 息 (如频点)。
需要说明的是, 该短距离承载的建立还可以是该受益 UE 根据 该第一重配消息中的第一短距离承载配置信息建立该短距离承载; 具体地, 该第一短距离承载配置信息包括支撑 UE的短距离信息 (如 频点)。
另夕卜,通过基站控制受益 UE或支撑 UE建立短距离承载具体包 括以下两种情况:
情况一: 受益 UE 发起业务时, 第一无线承载还未建立的, 此 时, 短距离承载的建立是在该受益 UE 根据第一重配消息建立第一 无线承载的同时建立的;
情况二, 受益 UE 发起业务时, 第一无线承载已建立, 此时, 受益 U E发起的业务需要根据第一重配消息重新配置第一无线承载, 则该短距离承载的建立是在重新配置该第一无线承载时建立的。
可选地, 该支撑 UE 获取基站配置的第二短距离承载标识和第 二无线承载标识, 其中, 该第二短距离承载标识在该支撑 UE 侧与 该短距离承载对应; 该第二无线承载标识与该第二无线承载对应。
则该支撑 UE 通过该第二短距离承载标识和该第二无线承载标 识的映射建立短距离承载和第二无线承载的映射。
进一步地, 该支撑 UE 将该第二短距离承载标识发送至该受益 UE , 以使得该受益 UE在向该支撑 UE发送数据时, 在该数据中携 带该第二短距离承载标识。
具体地, 当受益 UE向支撑 UE发送数据时, 数据中可携带第二 短距离承载标识, 使得受益 UE 能够根据该第二短距离承载标识识 别数据对应的短距离承载, 从而进行处理。
可选地, 该支撑 UE 向基站发送第一连接请求消息, 以便该基 站根据该第一连接请求消息中的第一受益承载信息对应配置第二无 线承载。
其中, 该第一受益承载信息包括: 该受益 UE 的标识、 该第一 无线承载标识、 第一短距离承载标识和 /或该第二短距离承载标识, 该第一短距离承载标识为该短距离承载在该受益 UE侧对应的标识。
进一步地, 在符合预设条件时, 该受益 UE或者支撑 UE向基站 发送译放请求消息, 并在该基站接收到该译放请求消息后, 该支撑 UE接收该基站发送的释放消息; 或者,
该受益 UE 向基站发送释放请求消息, 并在该基站接收到该释 放请求消息后, 该支撑 UE和受益 UE接收该基站发送的释放消息。
例如, 当支撑 UE与受益 UE之间的距离超过一预设距离时, 基 站接收支撑 UE或者受益 UE发送的释放请求消息, 并根据该释放请 求消息向支撑 UE发送释放消息,使得支撑 UE释放对应的第二无线 承载, 和第二无线承载与短距离承载的映射关系。 该预设距离可以 根据实际应用或经验值设置, 基站删除支撑 UE 的第二无线承载和 第二无线承载与第一短距离承载之间的映射; 并且基站删除受益 UE 的第一无线承载与第一短距离承载之间的映射。
具体地, 支撑 UE 会根据该释放消息删除短距离承载, 短距离 承载的删除也会使得第二无线承载删除。 当然, 基站也会发送重配 消息给受益 UE , 使得受益 UE删除第一无线承载或子承载与第一短 距离承载的映射关系。 具体的, 受益 UE与支撑 UE之间的短距离承 载也会被删除。 如果受益 UE与支撑 UE的短距离承载全部被删除, 相应地, 受益 UE与支撑 UE之间的短距离连接也会删除。
又如,当受益 UE取消相应业务导致受益 UE的第一无线承载被 删除时, 基站接收该受益 UE 发送的释放请求消息, 并根据该释放 请求消息向支撑 UE和受益 UE发送释放消息, 基站删除支撑 UE的 第二无线承载和第二无线承载与第一短距离承载之间的映射; 并且 基站删除受益 UE的第一无线承载与第一短距离承载之间的映射。
具体地, 支撑 UE或受益 UE (可根据实际应用 自行配置为支撑 UE或者受益 UE ) 会根据该释放消息删除短距离承载, 短距离承载 的删除也会使得第二无线承载和第一无线子承载删除, 另外, 如果 短距离承载全部被删除, 相应地, 短距离连接也会删除。

本发明实施例提供的一种以支撑 UE 为执行主体的短距离通信 方法、 设备和系统, 第一无线承载和短距离承载存在映射关系, 第 二无线承载和短距离承载存在映射关系, 同时第一无线承载和第二 无线承载存在映射关系, 这样, 各承载之间形成——映射, 从而使 得 UE 能够在短距离链路上区分数据信息传输对应的无线承载以进 行相应的处理。 本发明实施例提供一种短距离通信的方法, 如图 3 所示, 本实 施例的执行主体为基站, 包括:
S301、 基站向支撑 UE发送第二重配消息, 以便该支撑 UE根 据该第二重配消息建立短距离承载与第二无线承载的映射, 并通过 该第二无线承载和短距离承载的映射进行数据的接收与发送。
其中, 该第二无线承载为该支撑 UE 协助第一无线承载而建立 的无线承载,该短距离承载为协助该支撑 UE与受益 UE之间通信而 建立的承载, 该第一无线承载为该受益 UE 的受益无线承载且与该 短距离承载在受益 UE 侧映射; 该第一无线承载在基站侧与该第二 无线承载映射。
受益 UE与支撑 UE可以 自行建立短距离承载并且受益 UE可以 自行建立短距离承载与第一无线承载之间的映射。
S302、 基站通过该第一无线承载与该第二无线承载的映射进行 数据的发送或者接收。
可选地, 该第一无线承载为该受益 UE 的受益无线承载且与该 短距离承载在受益 UE侧映射也可以通过受益 UE建立, 具体地, 基 站向该受益 UE发送第一重配消息, 以便该受益 UE根据该第一重配 消息建立该短距离承载与该第一无线承载的映射, 并通过该第一无 线承载和短距离承载的映射进行数据的接收与发送。
可选地, 短距离承载的建立包括以下两种方式:
方式一: 该基站向该受益 UE 发送第一短距离承载配置信息, 以便该受益 UE根据该第一短距离承载配置信息建立该短距离承载。
方式二: 该基站向该支撑 UE 发送第二重配消息包括: 基站向 该支撑 UE发送第二短距离承载配置信息, 以便该支撑 UE根据该第 二短距离承载配置信息建立该短距离承载。
另夕卜,基站控制受益 UE或支撑 UE建立短距离承载具体包括以 下两种情况:
情况一: 受益 UE 发起业务时, 第一无线承载还未建立的, 此 时, 短距离承载的建立是在该受益 UE 根据第一重配消息建立第一 无线承载的同时建立的;
情况二, 受益 UE 发起业务时, 第一无线承载已建立, 此时, 受益 U E发起的业务需要根据第一重配消息重新配置第一无线承载, 则该短距离承载的建立是在重新配置该第一无线承载时建立的。 进一步地, 基站配置第一短距离承载标识和第一无线承载标识 并发送至该受益 UE ,其中,该第一短距离承载标识对应短距离承载, 该第一无线承载标识对应第一无线承载, 以便该受益 UE 根据该第 一短距离承载标识和第一无线承载标识建立短距离承载和第一无线 载的映射。
基站配置第二短距离承载标识和第二无线承载标识并发送至该 支撑 UE , 其中, 该第二短距离承载标识对应短距离承载, 该第二无 线承载标识对应第二无线承载, 以便该支撑 UE 根据该第二短距离 承载标识和第二无线承载标识建立短距离承载和第二无线承载的映 射。
可选地, 该基站向该受益 UE 发送第一重配消息, 以便该受益 UE 根据该第一重配消息建立该短距离承载与该第一无线子承载的 映射, 该第一无线子承载为在该第一无线承载中与该第二无线承载 一一对应的 7|载。
进一步地, 基站侧配置第二无线承载包括但不限于以下两种方 式:
方式一: 在基站向支撑 UE 发送第二重配消息前, 基站接收支 撑 UE 发送的第一连接请求消息, 并根据该第一连接请求消息中的 的第一受益承载信息对应配置该第二无线承载; 该第一受益承载信 息包括: 该受益 UE 的标识、 第一无线承载标识、 该第一短距离承 载标识和 /或该第二短距离承载标识。

进一步地, 在符合预设条件时, 该受益 UE或者该支撑 UE向基 站发送译放请求消息, 并在该基站接收到该译放请求消息后, 该支 撑 UE接收该基站发送的释放消息; 或者, 该受益 UE向基站发送释 放请求消息, 并在该基站接收到该译放请求消息后, 该支撑 UE 和 受益 UE接收该基站发送的释放消息。
例如, 当支撑 UE与受益 UE之间的距离超过一预设距离时, 基 站接收支撑 UE或者受益 UE发送的释放请求消息, 并根据该释放请 求消息向支撑 UE发送释放消息,使得支撑 UE释放对应的第二无线 承载, 和第二无线承载与短距离承载的映射关系。 该预设距离可以 根据实际应用或经验值设置, 基站删除支撑 UE 的第二无线承载和 第二无线承载与第一短距离承载之间的映射; 并且基站删除受益 UE 的第一无线承载与第一短距离承载之间的映射。
具体地, 支撑 UE 会根据该释放消息删除短距离承载, 短距离 承载的删除也会使得第二无线承载删除。 当然, 基站也会发送重配 消息给受益 UE , 使得受益 UE删除第一无线承载或子承载与第一短 距离承载的映射关系。 具体的, 受益 UE与支撑 UE之间的短距离承 载也会被删除。 如果受益 UE与支撑 UE的短距离承载全部被删除, 相应地, 受益 UE与支撑 UE之间的短距离连接也会删除。
又如,当受益 UE取消相应业务导致受益 UE的第一无线承载被 删除时, 基站接收该受益 UE 发送的释放请求消息, 并根据该释放 请求消息向支撑 UE和受益 UE发送释放消息, 基站删除支撑 UE的 第二无线承载和第二无线承载与第一短距离承载之间的映射; 并且 基站删除受益 UE的第一无线承载与第一短距离承载之间的映射。
具体地, 支撑 UE或受益 UE (可根据实际应用 自行配置为支撑 UE或者受益 UE ) 会根据该释放消息删除短距离承载, 短距离承载 的删除也会使得第二无线承载和第一无线子承载删除, 另外, 如果 短距离承载全部被删除, 相应地, 短距离连接也会删除。
下面针对受益 UE和支撑 UE通过第一短距离承载标识区分短距 离承载进行说明:
通过第一短距离承载标识区分短距离承载主要有三种方式: 方式一: 该第一短距离承载标识包含在该受益 UE MAC 层或 LLC层的 Ether type字段中。 例如, 以 LTE系统为例, 第一短距离承载标识的个数最大值不 超过 16个, 通常在 8个以下, 因此, 可以在 Ether type字段中直接 定义第一短距离承载标识 (如 8个), 来对应不同的短距离承载。
这种方式的好处是避免定义新的协议层。
方式二: 该第一短距离承载标识包含在该受益 UE的 MAC层或 LLC层的 Ether type字段所指示的协议层中。

另外, 若上述 Ether type 字段包含在 MAC 层, 则可以不需要 LLC层。 承上所述, 本发明实施例主要通过在支撑 UE 中建立支撑 UE 的第二无线承载与短距离承载之间的映射; 在受益 UE 中建立受益 UE的第一无线承载(或第一无线子承载)与短距离承载之间的映射; 同时,在基站中受益 UE的第一无线承载或子承载与支撑 UE的第二 无线承载之间也存在映射;
以下行数据传输为例, 基站根据受益 UE 的第一无线承载 (或 第一无线子承载) 与支撑 UE 的第二无线承载的映射关系, 可以选 择将数据通过第一无线承载直接发送到受益 UE , 或者选择将数据通 过支撑 UE的第二无线承载发送到支撑 UE。
当数据发送到支撑 UE , 该数据中携带第二无线承载标识, 使得 支撑 UE能够识别该数据对应的是第二无线承载, 支撑 UE根据第二 无线承载与短距离承载的映射关系, 将数据通过短距离承载发送至 受益 UE , 数据中携带第一短距离承载标识和 /或第二短距离承载标 识, 受益 UE在通过支撑 UE接收到该数据时, 通过该短距离承载与 第一无线承载 (或第一无线子承载) 的映射将数据发送到该受益 UE 的第一无线承载 (或第一无线子承载) 对应的协议层处理。
上行数据的传输与下行数据传输类似, 受益 UE 可以通过第一 无线承载将上行数据直接发送给基站, 也可以将数据通过第一无线 承载与短距离承载的映射关系, 通过短距离承载发送给支撑 UE , 短 距离承载发送的数据携带第一短距离承载标识和 /或第二短距离承 载标识; 支撑 UE 接收到该数据时, 通过该短距离承载与第二无线 承载的映射, 将数据通过第二无线承载发送到基站; 基站根据支撑 UE的第二无线承载与受益 UE的第一无线承载(或第一无线子承载) 的映射关系, 将数据发送到受益 UE 的第一无线承载 (或第一无线 子承载) 对应的协议层处理。

5501、 UE接收基站发送的数据信息。
其中, 该数据信息中携带该基站内配置的无线承载标识; 该无 线承载标识对应 UE建立的无线承载。
5502. UE根据该无线承载标识确定该基站发送的该数据信息对 应的无线承载。
进一步地, 该无线承载标识包含在该基站的 PDCP ( Packet Data Convergence Protocol , 分组数据汇聚协议) 层或者该 PDCP层之上 的协议层或者该 PDCP层与 RLC ( Radio Link Control , 无线链路控 制 )层之间的协议层或者该 RLC层或者该 RLC层与 MAC层之间的 协议层或者该 MAC层或者该 MAC层与 PHY层之间的协议层或者 该 PHY层。
需要说明的是, 上述的 UE可以为受益 UE。
这样, 基站通过在数据信息中添加无线承载标识, 使得 UE 在 接收到该数据信息时根据该无线承载标识确定该数据信 , 传输对应 的无线承载, 从而使得 UE 能够在短距离链路上区分数据信息传输 对应的无线承载以进行相应的处理。 本发明实施例提供一种短距离通信的方法, 如图 6所示, 本实 施例是以一个受益 UE 为例进行说明的, 本发明包括但不限于一个 受益 UE的情况, 该方法包括:

S604、 基站根据该第二连接请求消息中的第二受益承载信息配 置第二无线承载。
5605、 基站向受益 UE发送第一重配消息。
5606、 受益 UE根据该第一重配消息建立第一无线承载以及短 距离承载与第一无线承载的映射。
具体地, 受益 UE 从基站获取基站配置的第一短距离承载标识 和第一无线子承载标识, 其中, 该第一短距离承载标识在该受益 UE 侧与该短距离承载对应; 该第一无线承载标识与该第一无线承载对 应。 受益 UE 通过第一短距离承载标识和第一无线承载标识的映射 建立短距离承载和第一无线承载的映射。
通过第一短距离承载标识区分短距离承载主要有三种方式: 方式一: 该第一短距离承载标识包含在该受益 UE MAC 层或 LLC层的 Ether type字段中。
例如, 以 LTE系统为例, 第一短距离承载标识的个数最大值不 超过 16个, 通常在 8个以下, 因此, 可以在 Ether type字段中直接 定义第一短距离承载标识 (如 8个), 来对应不同的短距离承载。
这种方式的好处是避免定义新的协议层。
方式二: 该第一短距离承载标识包含在该受益 UE的 MAC层或 LLC层的 Ether type字段所指示的协议层中。
这里的协议层为新定义的协议层, 通过该 Ether type字段指示 该协议层。
这种方式的好处是时延较低, 对数据的处理效率高; 缺点是对 现有协议的影响较大。
方式三: 该第一短距离承载标识包含在该受益 UE的 MAC层或 LLC层的 Ether type字段所指示的网络层或传输层中的字段所指示 的协议层中。
这里的协议层也为新定义的协议层, 该 Ether type字段指示网 络层或传输层字段, 该网络层或传输层字段指示该新定义的协议层。
这种方式主要是将该协议层定义在协议栈的高层之上, 好处是 对现有的协议影响不大, 缺点是时延较高, 对数据的处理效率低且 会依赖高层操作系统。
需要说明的是, 若上述 Ether type字段包含在 MAC层, 则可以 不需要 LLC层。
另外,受益 UE会将第一短距离承载标识发送给支撑 UE ,这样, 当该支撑 UE向受益 UE发送数据时,数据中可携带第一短距离承载 标识, 使得受益 UE 能够根据该第一短距离承载标识识别数据对应 的短距离承载, 从而进行处理。
可选地, 该受益 UE建立短距离承载和第一无线子承载的映射。 其中, 该第一无线子承载为在该第一无线承载中与该第二无线承载 一一对应的 7|载。
进一步地, 在该受益 UE 建立短距离承载和第一无线子承载的 映射前, 该受益 UE 建立第一无线子承载, 该第一无线子承载的个 数与该支撑 UE的个数相同。
5607、 受益 UE向基站发送建立完成消息。
5608、 基站向支撑 UE发送第二重配消息。
5609、 支撑 UE根据该第二重配消息建立第二无线承载, 并建 立短距离承载与第二无线承载的映射。
具体地, 支撑 UE 从基站获取基站配置的第二无线承载标识和 第二短距离承载标识。 其中, 该第二短距离承载标识在该支撑 UE 侧与该短距离承载对应; 该第二无线承载标识与该第二无线承载对 应; 则该支撑 UE 通过该第二短距离承载标识和该第二无线承载标 识的映射建立短距离承载和第二无线承载的映射。
类似地, 第二短距离承载标识也对应包括以下三种方式: 方式一: 该第二短距离承载标识包含在该协助 UE MAC 层或 LLC层的 Ether type字段中。
方式二: 该第二短距离承载标识包含在该协助 UE的 MAC层或 LLC层的 Ether type字段所指示的协议层中。
方式三: 该第二短距离承载标识包含在该协助 UE的 MAC层或 LLC层的 Ether type字段所指示的网络层或传输层中的字段所指示 的协议层中。
其具体的说明参考上述对第一短距离承载标识的说明, 在此就 不再贅述了。
另外,支撑 UE会将第二短距离承载标识发送给受益 UE ,这样, 当该受益 UE向支撑 UE发送数据时,数据中可携带第二短距离承载 标识, 使得该支撑 UE 能够根据该第二短距离承载标识识别数据对 应的短距离承载, 从而进行处理。
5610、 支撑 UE向基站发送建立完成消息。
需要说明的是,上述步骤 S605至 S607和上述步骤 S608至 S610 是相互独立的过程, 并不存在绝对的顺序限制, 可以同时进行。
其中, 在基站侧第一无线承载与第二无线承载映射。 S61 1、 基站通过第一无线承载与第二无线承载的映射进行数据 的接收与发送, 该受益 UE 通过该第一无线承载和短距离承载的映 射进行数据的接收与发送, 该支撑 UE 通过该第二无线承载和短距 离承载的映射进行数据的接收与发送。
进一步地, 在符合预设条件时, 该受益 UE或者支撑 UE向基站 发送译放请求消息, 并在该基站接收到该译放请求消息后, 该支撑 UE接收该基站发送的释放消息; 或者,
该受益 UE 向基站发送释放请求消息, 并在该基站接收到该释 放请求消息后, 该支撑 UE和受益 UE接收该基站发送的释放消息。
例如, 当支撑 UE与受益 UE之间的距离超过一预设距离时, 基 站接收支撑 UE或者受益 UE发送的释放请求消息, 并根据该释放请 求消息向支撑 UE发送释放消息,使得支撑 UE释放对应的第二无线 承载, 和第二无线承载与短距离承载的映射关系。 该预设距离可以 根据实际应用或经验值设置, 基站删除支撑 UE 的第二无线承载和 第二无线承载与第一短距离承载之间的映射; 并且基站删除受益 UE 的第一无线承载与第一短距离承载之间的映射。
具体地, 支撑 UE 会根据该释放消息删除短距离承载, 短距离 承载的删除也会使得第二无线承载删除。 当然, 基站也会发送重配 消息给受益 UE , 使得受益 UE删除第一无线承载或子承载与第一短 距离承载的映射关系。 具体的, 受益 UE与支撑 UE之间的短距离承 载也会被删除。 如果受益 UE与支撑 UE的短距离承载全部被删除, 相应地, 受益 UE与支撑 UE之间的短距离连接也会删除。
又如,当受益 UE取消相应业务导致受益 UE的第一无线承载被 删除时, 基站接收该受益 UE 发送的释放请求消息, 并根据该释放 请求消息向支撑 UE和受益 UE发送释放消息, 基站删除支撑 UE的 第二无线承载和第二无线承载与第一短距离承载之间的映射; 并且 基站删除受益 UE的第一无线承载与第一短距离承载之间的映射。
具体地, 支撑 UE或受益 UE (可根据实际应用 自行配置为支撑 UE或者受益 UE ) 会根据该释放消息删除短距离承载, 短距离承载 的删除也会使得第二无线承载和第一无线子承载删除, 另外, 如果 短距离承载全部被删除, 相应地, 短距离连接也会删除。
需要说明的是, 若受益 UE转为空闲状态 (如没有业务交互), 则支撑 UE 也可能转为空闲状态, 此时, 仍然保留短距离承载, 这 样, 在受益 UE合支撑 UE转为活动状态时 (如受益 UE发起业务交 互), 不需要再建立短距离承载, 简化了信息交互流程, 提升了用户 体验。
另外, 若短距离承载不可用, 则删除该短距离承载对应的支撑 UE的短距离连接。
若增加新的支撑 UE , 则对应该新的支撑 UE建立短距离承载。 进一步地, 当受益 UE 由空闲状态转为活动状态时, 支撑 UE 也转为活动状态, 则触发上述步骤 S602至步骤 S61 1。
另外, 上述的支撑 UE 与受益 UE 之间的短距离连接可以是 WiFi、 蓝牙 ( Blue Tooth ) 或者 Zigbee等短距离通信技术, 甚至还 可以是有线网络如 Ethernet , 此时, 上述受益 UE与支撑 UE之间的 短距离承载为有线连接实现的承载。
通过上述步骤, 这样, 各承载之间形成——映射, 从而使得 UE 能够在短距离链路上区分数据信息传输对应的无线承载以进行相应 的处理。
