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 有做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。
本发明实施例所提供的方法可以应用于各种通信系统, 例如, 全球移 动通讯系统 (GSM: Global System of Mobile communication ) 网络、 通用 分组无线服务技术( GPRS : General Packet Radio Service ) 网络、 宽带码分 多址 ( WCDMA: Wideband Code Division Multiple Access ) 网络、 CDMA-2000 网 络 、 时 分 同 步 码 分 多 址 ( TD-SCDMA : Time Division- Synchronous Code Division Multiple Access ) 网络或全球微波互联 接入 ( WiMAX: Worldwide Interoperability for Microwave Access)网络等。
下面, 将以系统架构演进 ( SAE: System Architecture Evolution ) /长期 演进 ( LTE: Long-Term Evolution ) 网络为例进行说明, 当然本发明并不 限于这个场景。
示例性的, SAE/LTE 网络可以包括无线接入网节点 (如 eNodeB ) 、 核心网节点 (如移动管理实体 MME: Mobility Management Entity ) 、 服务 网关( S-GW: Server Gateway )和分组数据网关( P-GW: Packet Data Network Gateway ) 。
其中, 无线接入网节点用于向用户设备提供空中接口, 以便用户设备 接入 SAE/LTE网络。 核心网节点是控制面实体, 用于负责 SAE/LTE网络 的核心网控制功能, 执行用户设备的移动管理和会话管理。 服务网关和分 组数据网关可以是用户面实体, 用于向用户设备提供数据传输服务。
在用户设备开机附着到 SAE/LTE 网络之后, 核心网节点和 /或分组数 据网关将会给用户设备建立一个或多个作为系统承载的演进分组系统 ( Evolved Packet System, EPS )承载,从而用户设备可以经由所建立的 EPS 承载与第三方进行通信, 其中第三方可以是其它用户设备、 内容提供商的 服务器或服务提供商的服务器等。 每一个 EPS承载可以包括在用户设备和 无线接入网节点之间的无线承载、 用于用户设备的在无线接入网节点和服 务网关之间的 S1 承载和用于用户设备的在服务网关和分组数据网关之间 的 S5/S8 载。 S 1 载也称为 SAE/LTE 网络的无线接入网节点和核心网 节点之间的承载。
用户设备除了具备上述的某种蜂窝通信技术, 可能还具有某些短距离 通信技术能力,例如基于长期演进的设备到设备( LTE-D2D: LTE-Device to Device )技术,或基于 IEEE802. i l的 WiFi技术等。以蜂窝技术为 SAE/LTE, 短距离通信技术以 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, 当至少两个用户设备( User Equipment, 简称 UE ) 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可进行支撑,协助该一 个 UE 进行通信。 本发明中, 可以将该一个 UE命名为受益 UE、 被服务 UE或者被协助 UE, 将除该一个 UE之外的其他 UE命名为支撑 UE、 服务 UE或协助 UE, 上述 UE的命名只是本发明举的一个例子, 本发明中 UE 的命名包括但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下 行数据的最终接收方 (从蜂窝角度来看) 。 针对某一承载来说, 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的某一承载来说, 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 载角度来看的, 例如, UE1和 UE2组成 MUCC , 它们可以相互协助通 信, 这样, 站在 UE1 的某个承载角度, UE2可以支撑 UE1 的该承载, 于 是 UE1是受益 UE, UE2是支撑 UE。 而与此同时, UE1也可以支撑 UE2 的某个承载, 于是站在 UE2的这个承载的角度, UE2是受益 UE, 而 UE1 是支撑 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, 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 )发送给受益 UE。 当然, 数据也可以是直接到达受益 UE, 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。
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。
MUCC通信是以承载为粒度的, 对于某个承载, 如果第一用户设备的 承载被其他用户设备支撑, 则第一用户设备就是受益用户设备, 其他用户 设备就是支撑用户设备。
参见图 la, 本发明实施例提供的一种多用户协作通信的方法流程图, 如图所示, 可以包括以下步骤:
101a: 核心网节点获取至少两个用户设备的 MUCC能力标识信息, 所 述 MUCC能力标识用于标识所述用户设备的 MUCC能力, 所述 MUCC能 力包括: 第一受益能力、 第一支撑能力、 第一受益和第一支撑能力、 第二 受益能力或第二支撑能力;
示例性的, 第一受益能力可以指用户设备既可以作为受益用户设备; 也可以作为普通用户设备进行通信; 第一支撑能力可以指用户设备既可以 作为支撑用户设备, 也可以作为普通用户设备进行通信; 第一受益和第一 支撑能力可以表示所述用户设备既能够作为支撑用户设备, 又能够作为受 益用户设备, 还能够作为普通用户设备进行通信; 第二受益能力表示所述 用户设备只能作为受益用户设备进行 MUCC通信, 不能作为支撑用户设备 和普通用户设备; 第二支撑能力表示所述用户设备只能作为支撑用户设备 进行 MUCC通信, 不能作为受益用户设备和普通用户设备。 MUCC能力可 以用几个比特信息来表示。

示例性的, 核心网节点可以从签约数据库获取用户设备的签约信息, 然后根据用户设备的签约信息对用户设备的 MUCC能力进行签约判定,例 如, 可以取用户签约信息和用户设备的 MUCC能力标识信息中的交集生成 所述用户设备的协商 MUCC能力, 例如, 所述用户设备的签约允许所述用 户设备作为受益用户设备, 但不允许作为支撑用户设备, 核心网节点获取 的该用户设备的本身的 MUCC能力标识信息为第一受益和第一支撑能力, 则核心网节点生成的该用户设备的协商 MUCC能力为第一受益能力。本发 明其他实施例中, 用户设备的 MUCC能力标识信息可以是 UE本身的能力 信息, 也可以是与签约信息协商后的协商 MUCC能力。
403 : 核心网节点向无线接入网节点发送初始上下文建立请求, 所述 初始上下文建立请求包含所述用户设备的协商 MUCC能力标识信息。
404: 无线接入网节点根据至少两个所述用户设备的协商能力标识选 择所述 MUCC能力中具有支撑能力的用户设备和所述 MUCC能力中具有 受益能力的用户设备,使得在 MUCC通信中所述具有支撑能力的用户设备 对所述具有受益能力的用户设备的承载进行支撑。
示例性的, 对于具有受益能力的用户设备, 无线接入网节点根据该用 户设备的承载的 QoS信息来决定是否对该承载进行支撑, 若决定对该承载 进行支撑, 无线接入网节点可以选择具有支撑能力的用户设备作为该用户 设备的支撑用户设备, 优选的, 无线接入网节点可以选择无线连接质量最 好的具有支撑能力的用户设备作为该用户设备的支撑用户设备。 对于具有支撑能力的用户设备, 无线接入网节点可以选择该用户设备 作为具有受益能力的用户设备的支撑用户设备, 优选的, 无线接入网节点 可以选择无线连接质量最好的具有支撑能力的用户设备作为受益用户设备 的支撑用户设备。
优选的,无线接入网节点还可以获取用户设备的 MUCC优先级能力信 息, 这样无线接入网节点还可以根据用户设备的 MUCC 优先级对 MUCC 通信进行处理, 例如, 无线接入网节点可以选择 MUCC优先级低的具有支 撑能力的用户设备对具有受益能力的 MUCC 优先级高的用户设备的承载 进行支撑,但是不能选择 MUCC优先级高的具有支撑能力的用户设备对具 有受益能力的 MUCC优先级低的用户设备的承载进行支撑。 其中, 用户设 备的 MUCC优先级可以由无线接入网节点进行设定,也可以由核心网节点 进行设定 (如签约确定) , 然后发送给无线接入网节点, 还可以由用户设 备作为 MUCC能力标识信息的一部分发送给核心网节点, 然后核心网节点 再发送给无线接入网节点, 用户设备优先级的设定依据可以根据需要进行 选择, 本发明实施例对此不进行限制。 需要说明的是, 上述优先级高低是 相对而言, 相对优先级高的用户设备可以使用相对优先级低的用户设备作 为支撑用户设备; 相对优先级低的用户设备不能使用相对优先级高的用户 设备作为支撑用户设备。
另外, 在切换过程中, 用户设备的 MUCC能力标识信息可以从原无线 接入网节点发送至目标无线接入网节点。 例如, 可以从原无线接入网节点 直接发送至目标无线接入网节点, 或原无线接入网节点通过核心网节点中 转将 MUCC能力标识信息发送至目标无线接入网节点。

另外, 用户设备可以改变自己的 MUCC能力, 例如, 原来用户设备具 有第一支撑能力, 后来变更为第一受益和第一支撑能力, 即既有受益能力 又有支撑能力; 或者, 原来用户设备为第一受益和第一支撑能力, 即既有 受益能力又有支撑能力, 为了省电或者其他目的, 用户设备关闭了支撑能 力, 变更为第一受益能力, 优选的, 用户设备把变更后的 MUCC能力发送 给核心网节点,核心网节点再将用户设备变更后的 MUCC能力标识信息发 送给无线接入网节点, 以使得无线接入网节点根据用户设备变更后的 MUCC能力标识信息进行多用户协作通信的处理。 参见图 6, 可以包括:
601 : 用户设备改变 MUCC能力;
602: 用户设备向核心网节点发送更新后的 MUCC能力标识信息; 示例性的, 用户设备可以通过位置更新请求向核心网节点发送用户设 备更新后的 MUCC能力标识信息。
603 : 核心网节点向无线接入网节点发送初始上下文建立请求, 所述 初始上下文建立请求包含所述用户设备更新后的 MUCC能力标识信息; 示例性的, 核心网节点可以根据用户设备的签约信息对所述用户设备 发送的更新后的 MUCC能力标识信息进行签约判定, 生成所述用户设备更 新后的协商 MUCC能力标识信息;
核心网节点也可以不进行签约判定, 而直接使用用户设备发送的更新 后的 MUCC能力标识信息。 所以, 更新后的 MUCC能力标识信息可以包 含用户设备本身的更新后的 MUCC 能力标识信息或更新后的协商 MUCC 能力标识信息。
604: 无线接入网节点根据所述用户设备更新后的 MUCC能力标识信 息进行 MUCC通信的处理。
示例性的, 若所述用户设备更新后的 MUCC能力为不具有受益能力, 且所述用户设备作为受益用户设备正在进行 MUCC通信, 无线接入网节点 将支撑所述受益用户设备的支撑用户设备的支撑承载删除; 如果某个支撑 用户设备的支撑承载删除后没有其他活动承载, 无线接入网节点可能还会 将该支撑用户设备转为 idle空闲状态。
若所述用户设备更新后的 MUCC能力为不具有支撑能力,且所述用户 设备作为支撑用户设备正在进行 MUCC通信, 所述无线接入网节点将所述 支撑用户设备的支撑承载删除。 如果该用户设备的支撑承载删除后没有其 他活动承载, 无线接入网节点可能还会将该用户设备转为 idle空闲状态。
当然,所述更新后的 MUCC能力标识信息还可能是由于签约信息的改 变生成的, 如, 用户设备原来的签约是允许第一受益和第一支撑能力, 之 后改变签约变为允许第一支撑能力, 而用户设备的自身能力是第一受益和 第一支撑能力, 那么协商 MUCC能力就由第一受益和第一支撑能力改变成 第一支撑能力了,核心网节点同样需要将更新后的 MUCC能力标识信息发 送给无线接入网节点, 使得无线接入网节点根据所述用户设备更新后的 MUCC能力进行 MUCC通信的处理。 在这种情况下, 步骤 601、 602不会 执行, 即用户设备自身的 MUCC能力没有改变时, 不必通知网络, 但如果 用户设备的签约改变后, 也可以改变 MUCC的能力。
