  • Embodiments of the present invention relate to the field of communications, and, more particularly, to a method and apparatus for anchor point replacement.
  • the Wireless Communication Standardization Organization is discussing the delay reduction technology in the handover process based on the Long Term Evolution (LTE) system.
  • LTE Long Term Evolution
  • the main difficulty in bringing handover delay is concentrated on the reconfiguration of the terminal, the source base station, and the target base station.
  • the handover delay includes a downlink synchronization delay, an uplink synchronization delay, and a reconfiguration completion signaling delay on the target base station side after the terminal reconfiguration is completed.
  • a downlink synchronization delay since the downlink synchronization focuses on the synchronization between the terminal and the target base station, this step can be ignored when the target base station and the source base station are synchronized.
  • the reconfiguration complete delay is the same as the reconfiguration signaling configuration delay.
  • the key is the terminal processing delay. Therefore, the most important delay is the uplink synchronization delay.
  • the current uplink synchronization mainly involves the following steps:
  • the terminal initiates a contention-free random access procedure according to the preamble information configured in the reconfiguration signaling;
  • the base station After receiving the Preamble information, the base station calculates a Timing Advance (TA) of the uplink synchronization;
  • TA Timing Advance
  • the base station informs the terminal by using a random access response (RAR), and allocates an uplink grant (UL grant) resource to the terminal;

  • RRC Radio Resource Control
  • the timing advance is obtained by adopting a scheme in which the terminal performs measurement in advance, that is, after the terminal completes the measurement reporting, the base station selects the target base station, and then configures corresponding resources for the terminal, so that the terminal can perform uplink synchronization resource transmission with the target base station.
  • the target base station receives the signaling, the time advance amount is calculated and sent to the source cell; after receiving the time advance amount, the source cell sends a handover command including the time advance amount to the terminal.

Description

锚点更换的方法及设备 技术领域
本发明实施例涉及通信领域，并且更具体地，涉及一种锚点更换的方法及设备。
背景技术
目前无线通信标准化组织正基于长期演进(Long Term Evolution，LTE)***在切换过程中的时延缩短技术进行讨论。现有的LTE***中，带来切换时延的主要难点集中在终端、源基站和目标基站的重配置上。
现有的技术中，切换时延包括终端重配置完成后在目标基站侧的下行同步时延、上行同步时延和重配置完成信令时延。其中，由于下行同步重点在于终端与目标基站同步，当目标基站与源基站为同步的时，该步骤可以忽略。重配置完成时延与重配置信令配置时延相同，关键在于终端处理时延。因此最重要的时延即为上行同步时延。
当前上行同步主要涉及如下几个步骤：
(1)终端按照重配置信令中配置的前导(Preamble)信息发起无竞争的随机接入流程；
(2)基站收到该Preamble信息后，计算出上行同步的时间提前量(Timing Advance，TA)；
(3)基站将该TA通过随机接入响应(Random Access Response，RAR)告知终端，并为终端分配上行授权(Up Link grant，UL grant)资源；
(4)终端在UL grant资源使用配置的TA发送重配置完成消息。
现有的技术中，针对该流程具体的优化方案包括：
采用软切换的方式，即改变现有LTE***中终端的行为。当终端进行重配置时，并不将介质访问控制(Media Access Control，MAC)、无线链路控制(Radio Link Control，RLC)、分组数据汇聚协议(Packet Data Convergence Protocol，PDCP)等实体进行重置，即终端仍然保留与源基站的无线资源控制(Radio Resource Control，RRC)连接；同时终端在目标基站进行下行同步、上行同步并发送重配置信令，只有当终端成功连接到目标基站后，再断开与源基站的RRC连接。
在该方案中，时间提前量采用终端提前进行测算的方案得出，即当终端完成测量上报后，基站选择完目标基站，则为终端配置相应的资源使得终端能够与目标基站进行上行同步资源发送，当目标基站收到该信令后，则计算出时间提前量，并发送给源小区；源小区在收到时间提前量后将含有时间提前量的切换命令发送到终端。
该方案可以消除切换过程中建立RRC连接造成的时延，但是其要求终端需要支持同时保持与源基站和目标基站的RRC连接到，对终端的功能要求很高，增加了终端的复杂度，并且在切换过程中，基站与终端之间的数据传输是中断的，***的数据传输效率低，用户体验差。

应理解，本发明实施例的锚点更换的方法可以作为切换基站流程中的一部分流程。通过锚点更换可以完成基站的切换。其中，锚点是指对无线资源具有控制决策权的基站；锚点更换是指基站之间对于控制决策权的更换。
图1是本发明一个实施例的锚点更换的方法100。如图1所示，方法100可以包括：
S101，终端向源基站上报信号强度测量结果，该信号强度测量结果包括终端当前接收到的服务小区对应的基站(为切换之前的源基站)发射的信号的强度，以及服务小区附近其它小区对应的基站(包括之后要切换到的目标基站)发射的信号的强度。
具体地，该信号强度测量结果包括该终端当前接收到的该源基站的小区的信号的强度和该终端当前接收到的该目标基站的小区的信号的强度。终端上报信号强度测量结果可以根据现有的流程进行上报，本发明实施例对此不作限定。
相对应地，源基站接收终端上报的信号强度测量结果。
S102，源基站根据终端上报的信号强度测量结果，确定终端需要锚点更换(或者切换)到目标小区对应的基站(目标基站)，将目标小区添加为辅助小区，使得源基站和目标基站能够同时向终端发送用户数据。
当前的服务小区对应的基站将目标小区加为辅助小区(或称为“传输辅助小区”)，可以通过多连接技术，即设置主小区(Primary Cell，PCell)和辅小区(Secondary Cell，SCell)。换而言之，源基站的服务小区通过多连接技术将目标基站对应的小区添加为辅助小区。当有一个主小区和一个辅小区时，所基于的技术为双连接技术。此外，还可以通过其它技术添加辅助小区，本发明实施例对此不作限定。
对应S103和S104以及图2A，此时，用户数据可以通过主小区(当前的服务小区，对应源基站)调度，由服务小区下发，也可以由辅助小区(对应目标基站)下发，也可以由服务小区与目标小区同时下发。控制信令则由服务小区下发给终端。
应理解，本发明实施例中，根据终端上报的信号强度测量结果，源基站可以同时与一个或多个目标小区所属的基站建立辅助小区，本发明实施例对 此不作限定。
S105，源基站向目标基站发送锚点更换请求消息，其中，锚点更换请求消息用于请求将控制决策权由源基站切换至目标基站。当源基站与多个目标小区所属的基站建立辅助小区时，源基站选取多个目标小区对应基站中的一个目标基站发送锚点更换请求消息，即请求将无线资源控制(Radio Resource Control，RRC)权由源基站切换至目标基站，在此过程中用户数据链路保持不变，按照既有配置进行传输。相对应地，目标基站接收源基站发送的锚点更换请求消息。
其中，锚点更换请求消息包括终端的上下文信息、服务小区的***信息和针对终端的无线资源配置信息中的至少一种。以便于目标信息根据上述信息进行切换配置。
可选地，S106，目标基站在接收到源基站发送的锚点更换请求消息之后，可以根据锚点更换请求消息，向核心网设备发送路径倒换请求。该核心网设备可以为核心网路由器，例如SGW或PGW等。路径倒换请求用于指示将用户数据路径由核心网路由器到源基站的路径，倒换为由核心网路由器到目标基站的路径。应理解，也可以不执行S106，而是替代地执行S110，本发明实施例对此不作限定。
可选地，与图2B对应地，在源基站向目标基站发送锚点更换请求消息之后，源基站接收目标基站发送的锚点更换确认消息之前，可以执行S107，源基站可以直接向终端发送指示信息，该指示信息可以为配置信令，用于指示终端有关无线资源控制的配置已经由源基站转到了目标基站，该指示消息包括用于指示源基站的无线资源控制被释放的信息和目标基站的无线资源控制被配置的信息。换而言之，指示消息包括需向终端发送的RRC连接控制释放的相关信息及目标小区连接配置的相关信息。
或者替代S107地，可以执行S108，源基站也可以通过目标基站向终端发送指示消息。即目标基站接收源基站发送的指示消息，并向终端转发指示消息。
应理解，如图2B所示，在源基站向目标基站发送锚点更换请求消息之后，接收到目标基站发送的锚点更换确认消息之前，用户数据可以由源基站和/或目标基站下发。指示消息等控制信令由源基站决定，即RRC控制权仍在源基站处。可以由源基站直接发给终端，也可以通过目标基站发送给终端。
S109，目标基站向源基站发送锚点更换确认消息，该锚点更换确认消息用于确认锚点更换请求消息，具体可以包括在目标基站侧能够建立的有关终端的无线承载、相应的服务质量(Quality of Service，QoS)等信息。相对应地，源基站接收目标基站发送的锚点更换确认消息。
在S109目标基站向源基站发送锚点更换确认消息的同时，执行S110，目标基站与终端建立RRC连接控制链路，此时，RRC控制权由源基站切换至目标基站处。
替代S106地，可以执行S111，在源基站接收到目标基站发送的锚点更换确认消息之后，源基站根据锚点更换确认消息，向核心网设备发送路径倒换请求，以便于核心网设备进行切换的相关配置。
替代S107或S108地，在S109目标基站向源基站发送锚点更换确认消息之后，执行S112目标基站向终端发送上文中描述的指示消息。
或者替代S107地，在S109目标基站向源基站发送锚点更换确认消息之后，可以执行S113目标基站通过源基站向终端发送指示消息。即源基站接收目标基站发送的指示消息，并向终端转发指示消息。
应理解，如图2C所示，在目标基站向源基站发送锚点更换确认消息之后，用户数据可以由源基站和/或目标基站下发。指示消息等控制信令由目标基站决定，即RRC控制权已经由源基站切换至目标基站。可以由目标基站直接发给终端，也可以通过源基站发送给终端。
S114，当源基站的信号质量较差时，具有RRC控制权的目标基站向终端发送去激活消息，去激活消息用于指示终端对源基站进行去激活。相应地，终端接收目标基站发送的去激活消息。
S115，终端根据去激活消息，对源基站进行去激活。具体地，终端可以将原服务小区(源基站)从终端的服务列表中删除。
应理解，本发明实施例的锚点更换请求可以承载在现有的技术中的切换请求消息中，即锚点更换请求消息可以为切换请求消息；类似地，锚点更换确认可以承载在现有的技术中的切换确认消息中，即锚点更换确认消息可以为切换确认消息。换而言之，本发明实施例的锚点更换请求、锚点更换确认等可以基于现有的技术的消息，也可使用新的消息进行传输，本发明实施例对此不作限定。
应理解，在本发明的各种实施例中，上述各过程的序号的大小并不意味 着执行顺序的先后，各过程的执行顺序应以其功能和内在逻辑确定，而不应对本发明实施例的实施过程构成任何限定。
还应理解，上述方案中有些步骤是可以相互替代，或者是可以省略的。将各步骤按照逻辑进行组合，可以得到以下方案，例如，(S101，S102，S103和/或S104，S105，S106，S107或S108，S109，S110，S114，S115；)或者，(S101，S102，S103和/或S104，S105，S107或S108，S109，S110，S111，S114，S115；)或者(S101，S102，S103和/或S104，S105，S106，S109，S110，S112或S113，S114，S115；)或者(S101，S102，S103和/或S104，S105，S109，S110，S111，S112或S113，S114，S115)等等，但本发明实施例不限于此。
