为使本发明实施例的目的、 技术方案和优点更加清楚, 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。
本发明的技术方案, 可以应用于各种无线通信系统, 例如: 全球移动通
信系统 (Global System for Mobile Communications, 简称: GSM) 、 通用分 组无线业务(General Packet Radio Service,简称: GPRS )系统、码分多址(Code Division Multiple Access, 简称: CDMA) 系统、 CDMA2000系统、 宽带码分 多址 (Wideband Code Division Multiple Access, 简称: WCDMA) 系统、 长 期演进 (Long Term Evolution, 简称: LTE) 系统或全球微波接入互操作性 (World Interoperability for Microwave Access, 简称: WiMAX) 系统等。
基站,可以是 GSM系统、 GPRS系统或 CDMA系统中的基站控制器(Base Station Controller,简称: BSC),还可以是 LTE系统中的演进型基站(Evolved NodeB ,简称: eNB ),还可以是 WiMAX网络中的接入服务网络的基站(Access Service Network Base Station, 简称: ASN BS ) 等网元。 UE可以是手机或平 板电脑等设备。
在此对逻辑信道、 传输信道和物理信道进行说明。
逻辑信道是为无线连接 (即 CP连接和 UP连接, 其中, CP连接为传输 控制数据的无线连接, UP连接为传输业务数据的无线连接)提供数据传输业 务, 逻辑信道可以分为控制逻辑信道和业务逻辑信道, 控制逻辑信道用于承 载控制数据 (即 CP连接上的数据) , 业务逻辑信道用于承载业务数据 (即 UP连接上的数据) 。
传输信道用于定义数据在空口上传输的方式和特性 (例如传输速率、 误 码率、 时延等) 。 物理信道定义数据在空口上传输的物理资源, 具体可以包 括载频、 扰码、 信道化码 (可选的) 、 开始和结束时间 (有一段持续时间) 等。
逻辑信道用于定义传输数据的类型, 因此, 基站与 UE之间传输的数据 先承载在相应的逻辑信道上, 承载在逻辑信道上的数据可能是独立成块的数 据流, 也可能是夹杂在一起但是有确定起始位的数据流。 承载有数据的逻辑 信道将映射到传输信道上, 即对承载在逻辑信道中数据进行特定处理并加上 传输格式等指示信息, 然后将承载有数据的传输信道映射到物理信道上, 即 将承载在传输信道中的数据按照该数据所属的 UE和该数据的功用确定其载 频、 扰码、 扩频码、 开始和结束时间进行相关的操作, 并在最终调制为模拟 射频信号发射出去。
因此, CP连接所占用的逻辑信道和 UP连接所占用的逻辑信道通常是不
同的, CP连接所占用的传输信道和 UP连接所占用的传输信道通常是相同的, 例如, 传输信道的传输速率、 误码率和时延都是相同的。 CP连接所占用的物 理信道和 UP连接所占用的物理信道通常也是相同的, 例如, 物理信道的载 频、 扰码、 信道化码 (可选的) 、 开始和结束时间 (有一段持续时间) 等都 是相同的。 CP连接和 UP连接占用传输信道的方式可以为 CP连接和 UP连 接的数据传输通过调度的方式复用在传输信道; CP连接和 UP连接占用物理 信道的方式可以为 CP连接和 UP连接的数据传输通过调度的方式复用在物理 信道上。 因而, 可能不能同时满足 CP连接和 UP连接的 QoS要求, 用户体 验可能得不到保证。
图 1为本发明无线连接建立方法实施例一的流程图, 如图 1所示, 本实 施例的方法可以包括:
S101、 基站根据 CP连接的配置参数, 与 UE建立所述 CP连接, 所述 CP连接的配置参数用于指示所述 CP连接所占用的传输信道和所述 CP连接 所占用的物理信道。
S102、所述基站根据 UP连接的配置参数,与所述 UE建立所述 UP连接, 所述 UP连接的配置参数用于指示所述 UP连接所占用的传输信道和所述 UP 连接所占用的物理信道。
本实施例中, 基站根据 CP连接的配置参数, 与 UE建立 CP连接, 从而 该 UE的 CP连接位于该基站所控制的一个小区, 即该 UE与该基站控制的小 区建立该 CP连接。 基站也可以根据 UP连接的配置参数, 与 UE建立 UP连 接, 从而该 UE的 UP连接位于该基站所控制的的一个小区, 即该 UE与该基 站控制的小区建立该 UP连接。 该 CP连接与该 UP连接可以同时位于该基站 所控制的同一个小区, 也可以分别位于该基站所控制的不同小区。不论该 CP 连接与该 UP连接位于该基站所控制的同一小区还是不同小区,所述 CP连接 所占用的传输信道和所述 UP连接所占用的传输信道不同, 例如: CP连接和 UP连接的传输速率、 误码率和时延中至少一个是不同的; 所述 CP连接所占 用的物理信道和所述 UP连接所占用的物理信道不同, 例如 CP连接和 UP连 接的所占用的时隙不同和所占用的频率中至少一个是不同的。 由于该 UE的 UP连接和 CP连接所占用的传输信道不同,物理信道也不同,从而实现了 CP 连接和 UP连接分离。 CP连接和 UP连接的数据传输在各自的传输信道和物
理信道上, 可以满足各自 QoS要求。
因此, 当该 UE的 CP连接的配置发生变化时, 只需要重新配置 CP连接 所占用的传输信道和物理信道即可,可以不需要重新配置该 UE的 UP连接所 占用的传输信道和物理信道; 当该 UE的 UP连接的配置发生变化时, 可以只 需要重新配置该 UP连接所占用的传输信道和物理信道即可, 不需要重新配 置该 CP连接所占用的传输信道和物理信道; 这样 CP连接与 UP连接不会互 相影响, 也就不会导致 UE与基站之间的通信连接掉话, 从而减少了时延, 提高了网络吞吐量。 而且 CP连接与 UP连接具有不同的 QoS要求, 因此, 将 CP连接与 UP连接进行分离可以更加灵活地保证 CP连接和 UP连接的 QoS 要求, 而且不会相互影响, 提高了 UP连接上数据传输的灵活性。
图 2为本发明实施例提供的空口协议栈的第一种示意图, 如图 2所示, SRB和 DRB承载在层 (Layer, 简称: L) 2和 L1中不同的信道上, 也就是 SRB和 DRB分别承载在不同的传输信道和物理信道上,表示 UE与无线接入 网 (Radio Access Network, 简称: RAN) (例如基站)之间的 CP连接和 UP 连接配置在不同的传输信道和物理信道上, SRB承载 CP连接的数据, CP连 接的数据包括无线资源控制协议(Radio Resource Control, 简称: RRC)信令 以及 NAS信令等 L3信令 (包括与 DRB相关的信令) , DRB承载 UP连接 的数据。其中, L2指的是分组数据汇聚协议(Packet Data Convergence Protocol, 简称: PDCP) /无线链路控制 (Radio Link Control, 简称: RLC) MAC, LI 是指物理层 (Physical Layer) 。
可选地, 与所述 UE建立 UP连接的小区和与所述 UE建立 CP连接的小 区可以是同一个小区, 也可以是同一基站控制的不同小区。
可选地, 与所述 UE建立 CP连接的小区为基站所控制的第一小区, 与所 述 UE建立 UP连接小区为基站所控制的第二小区, 其中, 该第一小区工作的 无线接入技术 (Radio Access Technology, 简称: RAT) 与第二小区工作的 RAT相同, 也就是 UE与同系统中的不同小区分别建立 UP连接和 CP连接, UE的 CP连接和 UP连接同样分别配置在不同的传输信道和物理信道上, 如 图 3所示, 第一小区与第二小区工作的 RAT均为 RAT1。
可选地, 上述第一小区工作的 RAT和第二小区工作的 RAT不同, 也就 是 UE与不同系统中的小区分别建立 UP连接和 CP连接, UE的 CP连接和
UP连接同样分别配置在不同的传输信道和物理信道上, 如图 4所示, 第一小 区工作的 RAT为 RATI, 第二小区工作的 RAT为 RAT2。
本发明实施例提供的无线连接建立方法, 基站和 UE在建立无线连接时, UE的 CP连接所占用的传输信道和 UP连接所占用的传输信道不同,并且 UE 的 CP连接所占用的物理信道和 UP连接所占用的物理信道也不同,从而实现 了同一 UE的 CP连接和 UP连接分离,在 UE所入的同一小区中, CP连接或 UP连接发生变化时, CP连接和 UP连接不会同时中断, 保证通信连接不掉 话, 提高了用户体验, 同时减少了时延, 增加了网络吞吐量, 还提高了 UP 连接上数据传输的灵活性。
图 5为本发明无线连接建立方法实施例二的流程图, 如图 5所示, 本实 施例的方法可以包括:
S201、 UE根据 CP连接的配置参数, 与基站建立所述 CP连接, 所述 CP 连接的配置参数用于指示所述 CP连接所占用的传输信道和所述 CP连接所占 用的物理信道。
S202、所述 UE根据 UP连接的配置参数,与所述基站建立所述 UP连接, 所述 UP连接的配置参数用于指示所述 UP连接所占用的传输信道和所述 CP 连接所占用的物理信道。
本实施例中, 本实施例中, UE根据 CP连接的配置参数, 与基站建立 CP连接, 从而该 UE的 CP连接位于该基站所控制的一个小区, 即该 UE与 该基站控制的小区建立该 CP连接。 UE也可以根据 UP连接的配置参数, 与 基站建立 UP连接, 从而该 UE的 UP连接位于该基站所控制的的一个小区, 即该 UE与该基站控制的小区建立该 UP连接。 该 CP连接与该 UP连接可以 位于该基站所控制的同一个小区, 也可以位于该基站所控制的不同小区。 不 论该 CP连接与该 UP连接位于该基站所控制的同一小区还是不同小区,所述 CP连接所占用的传输信道和所述 UP连接所占用的传输信道不同, 所述 CP 连接所占用的物理信道和所述 UP连接所占用的物理信道不同。由于该 UE的 UP连接和 CP连接所占用的传输信道不同, 物理信道也不同, 从而该 UE的 CP连接和 UP连接在传输信道和物理信道均实现了分离, 进而实现了同一 UE的 CP连接和 UP连接分离。
因此, 当该 UE的 CP连接的配置发生变化时, 只需要重新配置 CP连接
所占用的传输信道和物理信道即可,不需要重新配置该 UE的 UP连接所占用 的传输信道和物理信道; 当该 UE的 UP连接的配置发生变化时,只需要重新 配置该 UP连接所占用的传输信道和物理信道即可,不需要重新配置该 CP连 接所占用的传输信道和物理信道; 这样 CP连接与 UP连接不会互相影响, 也 就不会导致 UE与基站之间的通信连接掉话, 从而减少了时延, 提高了网络 吞吐量。 而且 CP连接与 UP连接具有不同的 QoS要求, 因此, 将 CP连接与 UP连接进行分离可以更加灵活地保证 CP连接和 UP连接的 QoS要求, 而且 不会相互影响, 提高了 UP连接上数据传输的灵活性。
可选地, 与所述 UE建立 UP连接的小区和与所述 UE建立 CP连接的小 区可以是同一个小区。
可选地, 与所述 UE建立 CP连接的小区为基站所控制的第一小区, 与所 述 UE建立 UP连接小区为基站所控制的第二小区, 其中, 该第一小区工作的 RAT与第二小区工作的 RAT相同,也就是 UE与同系统中的不同小区分别建 立 UP连接和 CP连接, UE的 CP连接和 UP连接同样分别配置在不同的传输 信道和物理信道上,如图 3所示,第一小区与第二小区工作的 RAT均为 RATI。
可选地, 上述第一小区工作的 RAT和第二小区工作的 RAT不同, 也就 是 UE与不同系统中的小区分别建立 UP连接和 CP连接, UE的 CP连接和 UP连接同样分别配置在不同的传输信道和物理信道上, 如图 4所示, 第一小 区工作的 RAT为 RATI, 第二小区工作的 RAT为 RAT2。
本发明实施例提供的无线连接建立方法, UE和基站在建立无线连接时,
UE的 CP连接所占用的传输信道和 UP连接所占用的传输信道不同,并且 UE 的 CP连接所占用的物理信道和 UP连接所占用的物理信道也不同,从而实现 了同一 UE的 CP连接和 UP连接分离,在 UE所入的同一小区中, CP连接或 UP连接发生变化时, CP连接和 UP连接不会同时中断, 保证通信连接不掉 话, 提高了用户体验, 同时减少了时延, 增加了网络吞吐量, 还提高了 UP 连接上数据传输的灵活性。
图 6为本发明无线连接建立方法实施例三的流程图, 如图 6所示, 本实 施例的方法包括:
S301、 基站向 UE发送 CP连接的配置参数和 UP连接的配置参数。
S302、 所述 UE接收所述基站发送的所述 CP连接的配置参数和所述 UP
连接的配置参数。
S303、所述基站与所述 UE根据所述 CP连接的配置参数和所述 UP连接 的配置参数, 建立所述 CP连接和所述 UP连接。
本实施例中, 基站可以通过 UE的随机接入过程, 确定该 UE的 CP连接 的配置参数, 以建立 CP连接, 并且当 UE需要进行业务时, UE与核心网设 备会进行业务协商过程, 业务协商过程完成后, 核心网设备会通知该基站建 立该 UE的 UP连接, 然后该基站再确定该 UP连接的配置参数, 例如: 核心 网设备会向基站发送无线接入承载指示信息, 该无线接入承载指示信息可以 包括: 建立该 UE的无线接入承载的速率、 时延、 误码率等业务 QoS信息, 基站根据核心网设备发送的无线接入承载指示信息、 CP连接所占用的传输信 道与 UP连接所占用的传输信道不同以及 CP连接所占用的物理信道与 UP连 接所占用的物理信道不同, 来确定该 UE的 UP连接的配置参数, 以建立 UP 连接。 因此, 本实施例中, 基站所确定的 CP连接的配置参数用于指示该 CP 连接所占用传输信道和物理信道, 进一步地, CP连接的配置参数用于指示该 CP连接所占用的逻辑信息; 基站所述确定 UP连接用于指示该 UP连接所占 用的传输信道和物理信道, 进一步地, UP连接的配置参数用于指示该 UP连 接所占用的逻辑信道; 需要说明的是, CP连接所占用的逻辑信道与 UP连接 所占用的逻辑信道不同, CP连接所占用的传输信道与 UP连接所占用的传输 信道不同, CP连接所占用的物理信道与 UP连接所占用的物理信道不同, 由 于基站将 UP的 CP连接和 UP连接分别配置在不同的传输信道和物理信道上, 那么 UE的 CP连接和 UP连接实现了分离。
可选地, 若基站确定与该 UP连接和 CP连接位于同一小区(例如第一小 区) , 则由基站所控制的第一小区确定该 UE的 CP连接的配置参数和 UP连 接的配置参数。 从而 UE所建立的 CP连接和 UP连接位于同一小区。
可选地, 若基站确定该 UP连接和 CP连接位于不同小区, 例如: 该 CP 连接位于基站控制的第一小区, 该 UP连接位于该基站所控制的第二小区, 在第一小区确定该 UE的 CP连接的配置参数后, 该第一小区判次 UP连接需 要位于该基站控制的第二小区,则第一小区再向第二小区发送 UE的 UP连接 建立请求, 第二小区根据第一小区发送的 UE的 UP连接建立请求确定该 UE 的 UP连接的配置参数。 例如: 第一小区会将从核心网设备接收的无线接入
承载指示信息发送给第二小区, 该无线接入承载指示信息可以包括: 建立该
UE的 DRB承载的速率、 时延、 误码率等 QoS信息, 第二小区再根据该无线 接入承载指示信息确定 UE的 UP连接的配置参数, 第二小区再将该 UE的 UP连接的配置参数包括在 UE的 UP连接建立响应中发送给第一小区, 第一 小区再从 UE的 UP连接建立响应中获取该 UE的 UP连接的配置参数。 从而 UE所建立的 CP连接位于第一小区, UE所建立的 UP连接位于第二小区。
本实施例中, 基站在确定 UE的 CP连接的配置参数和 UP连接的配置参 数之后, 基站可以根据 UE的 CP连接的配置参数和 UP连接的配置参数生成 无线资源配置消息, 该无线资源配置消息包括所述 CP连接配置参数和所述 UP连接的配置参数, 然后基站通过公共连接向 UE发送无线资源配置消息, 从而使得 UE接收到无线资源配置消息后,获取无线资源配置消息中的 CP连 接的配置参数和 UP连接的配置参数, 然后 UE根据 CP连接的配置参数和 UP连接的配置参数, 与基站建立 CP连接和 UP连接, 基站也根据发送给该 UE的 CP连接的配置参数和 UP连接的配置参数,与该建立 CP连接和 UP连 接。 从而 UE建立的 CP连接与 UP连接占用在不同的传输信道上, 而且 UE 建立的 CP连接与 UP连接占用在不同的物理信道上, 因此, UE的 CP连接 和 UP连接实现了分离。
下面对 UE的 CP连接的配置参数和 UP连接的配置参数进行举例说明, 如下所示为无线资源配置消息中指示 UE的 CP连接的配置参数和 UP连接的 配置参数的信元。 mac-MainConfig for SRB是配置 CP连接的传输信道参数, mac-MainConfig for DRB 是配置 UP 连接的传输信道参数, PhysicalconfigDedicated for SRB 是配置 CP 连接的物理信道参数, PhysicalconfigDedicated for DRB是配置 UP连接的物理信道参数。 其它部分 与现有技术中的一致, 此处不再赘述。

当 UE需要进行业务时, UE与核心网设备会进行业务协商过程, 业务协 商过程完成后, 核心网设备会通知基站建立该 UE的 UP连接,然后基站再确 定建立该 UP连接的配置参数, 例如: 核心网设备会向基站发送无线接入承 载指示信息, 该无线接入承载指示信息可以包括: 建立该 UE的 DRB承载的 速率、 时延、 误码率等业务 QoS信息, 基站根据核心网设备发送的无线接入 承载指示信息、 CP连接所占用的传输信道与 UP连接所占用的传输信道不同 以及 CP连接所占用的物理信道与 UP连接所占用的物理信道不同,来确定该 UE的 UP连接的配置参数, 以建立 UP连接, 本实施例中, 基站确定的 UE 的 UP连接的配置参数用于指示该 UP连接所占用的传输信道和物理信道,进 一步地还可以指示该 UP连接所占用的逻辑信道,基站可以将该 UP连接的配 置参数携带在另一无线资源配置消息并通过已建立的 CP连接发送给该 UE, 相应地, UE可以通过该 UE的 CP连接接收基站发送的 UP连接的配置参数。 然后基站与 UE可以根据该 UP连接的配置参数, 建立 UP连接。
