技术领域 Technical field
本发明涉及通信技术, 尤其涉及一种重定向信息上报及获取方法、 装置。 背景技术 The present invention relates to communication technologies, and in particular, to a method and an apparatus for reporting and acquiring redirection information. Background technique
SON ( Synchronous Optical Net, 同步光纤网 )技术是一种网络自优化技 术, 网络通过搜集用户信息, 确定对网络参数的优化调整。 一种典型的应用 是, 移动健壮性自优化。 即 UE记录在网络中发生无线链路失败或者切换失败 的相关信息,当 UE再次和网络建立连接时, UE将记录的失败信息上报给网络。 网络分析统计大量 UE的失败信息后, 能够推断出发生失败问题的原因, 进一 步调整移动性相关的参数。 通过移动性参数的自动优化调整, 就可以避免网 络中再出现相同的失败事件。 SON (Synchronous Optical Net) technology is a network self-optimization technology. The network collects user information to determine the optimal adjustment of network parameters. A typical application is mobile robustness self-optimization. That is, the UE records related information that the radio link fails or the handover fails in the network. When the UE establishes a connection with the network again, the UE reports the recorded failure information to the network. After the network analyzes the failure information of a large number of UEs, it can infer the cause of the failure problem and further adjust the mobility related parameters. By automatically optimizing the mobility parameters, you can avoid the same failure events in the network.
当前, 通过移动健壮性自优化技术, 网络能够识别和优化过早切换, 过 晚切换, 切换到错误的小区以及乒乓切换等问题场景。 Currently, through the mobile robustness self-optimization technology, the network can identify and optimize problem scenarios such as premature handover, late handover, handover to the wrong cell, and ping-pong handover.
但是网络中, 还有一种很重要的移动性场景是重定向场景。 重定向方式 由于操作简单, 在现有网络中广泛存在, 重定向也会由于参数设置的不合理, 也会导致将 UE切换到不合适的频点或者导致过早的重定向切换等问题。 But there is another important mobility scenario in the network that is a redirect scenario. Redirection method Due to its simple operation, it is widely used in existing networks. Redirection is also caused by unreasonable parameter settings. It can also cause problems such as switching UEs to inappropriate frequency points or causing premature redirect switching.
但目前, 网络侧无法获得 UE的重定向信息, 更无法进行后续的优化操作。 发明内容 However, at present, the network side cannot obtain the redirect information of the UE, and the subsequent optimization operation cannot be performed. Summary of the invention

下面, 根据不同的实际情况, 通过具体实施例进行详细说明: In the following, according to different actual situations, a detailed description will be given by way of specific embodiments:
实施例一、 Embodiment 1
该实施例中, UE接收到第一小区的基站发送的重定向命令消息后, 根据 该重定向命令, 重定向到第二小区, 但 RRC连接建立失败, UE记录相关信 息, 并在再次发起 RRC连接时, 或建立 RRC连接后, 发送给相应的基站。 In this embodiment, after receiving the redirect command message sent by the base station of the first cell, the UE redirects to the second cell according to the redirect command, but the RRC connection setup fails, the UE records related information, and initiates RRC again. When connected, or after establishing an RRC connection, it is sent to the corresponding base station.
此时, 步骤 S101中, 记录重定向事件的相关信息, 具体包括: At this time, in step S101, the related information of the redirect event is recorded, which specifically includes:
在确定与第二小区的基站的无线链路控制 RRC连接建立失败后, 记录第 一信息, 第一信息中包括: 第一小区标识、 第二小区标识; After determining that the radio link control RRC connection establishment of the base station of the second cell fails, the first information is recorded, where the first information includes: a first cell identifier and a second cell identifier;
RRC连接建立过程是由重定向命令消息, 触发建立的。 也就是说, 第一 小区向 UE发送重定向命令时, UE的业务并没有结束。 当 UE接收重定向选 择一个小区后, 仍然会发起业务建立过程, 业务建立过程包含 RRC连接建立 过程。 The RRC connection establishment process is triggered by a redirect command message. That is to say, when the first cell sends a redirect command to the UE, the service of the UE does not end. After the UE receives the redirect and selects a cell, the service establishment process is still initiated, and the service establishment process includes an RRC connection establishment process.
步骤 S102中, UE向网络侧上报重定向事件的相关信息, 具体包括: UE向第三小区发起 RRC连接建立时或者 UE在第三小区进入连接态后,
向第三小区发送包括第一信息的第一重定向指示信息, 由第三小区的基站向 第一小区的基站发送第二重定向指示信息, 第二重定向指示信息包括: 第一 重定向指示信息; In step S102, the UE reports the related information of the redirection event to the network, and the method includes: when the UE initiates an RRC connection setup to the third cell, or after the UE enters the connection state in the third cell, Transmitting the first redirection indication information including the first information to the third cell, where the base station of the third cell sends the second redirection indication information to the base station of the first cell, where the second redirection indication information includes: a first redirection indication information;
第三小区与第二小区是相同小区或不同小区。 The third cell and the second cell are the same cell or different cells.
进一步, 第一信息中还可以包括如下之一或组合: Further, the first information may further include one or a combination of the following:
跟踪区或者路由区标识、 目标频点信息、 UE在第一' 区的标识、 UE收 到重定向命令到发生 RRC连接建立失败的时间、 UE进行相关测量的测量结 果; The tracking area or the routing area identifier, the target frequency point information, the identifier of the UE in the first 'area, the time when the UE receives the redirection command to the time when the RRC connection establishment fails, and the measurement result of the relevant measurement by the UE;
第二重定向指示信息中还可以包括如下之一或组合: The second redirection indication information may further include one or a combination of the following:
当前距离 RRC连接建立失败的间隔时间以及第三小区标识、 第一小区标 识。 The interval between the current distance RRC connection establishment failure and the third cell identifier and the first cell identifier.
当第二小区的频点和第一小区指示的频点不同时, 可以认为是重定向到 错误的频点或者重定向失败, 此时, 第二重定向指示信息还包括: UE重定向 到错误的频点和 /或 UE重定向失败。 When the frequency of the second cell is different from the frequency indicated by the first cell, it may be considered to be redirected to the wrong frequency or the redirection fails. At this time, the second redirection indication information further includes: the UE redirects to the error. The frequency and/or UE redirection failed.
较佳的, UE还可以将第一信息添加到连接建立失败变量中, 以便于 UE 及网络侧后续通过该变量获取相应的信息。 Preferably, the UE may further add the first information to the connection establishment failure variable, so that the UE and the network side subsequently obtain the corresponding information by using the variable.
下面, 如图 2所示, 以第三小区和第二小区是不同小区为例, 进行详细 说明, 包括: In the following, as shown in FIG. 2, the third cell and the second cell are different cells, and the detailed description includes:
步骤 S201、 第一小区的基站向 UE发送重定向命令消息, 该重定向命令 消息中包括: 频点信息、 重定向事件上 信息; Step S201: The base station of the first cell sends a redirect command message to the UE, where the redirect command message includes: frequency point information, information on the redirect event;
其中,频点信息用于指示 UE在该频点上选择合适的小区,进行小区驻留, 频点信息可以是绝对无线频道编号 (Absolute Radio Frequency Channel Number, ARFCN ), 重定向事件上报信息则用于指示 UE是否记录重定向事 件的相关信息并上报,若 UE默认需要记录重定向事件的相关信息并上报, 则 该重定向命令消息不需要携带重定向事件上报信息。 The frequency point information is used to indicate that the UE selects a suitable cell at the frequency point, and performs cell camping. The frequency point information may be an Absolute Radio Frequency Channel Number (ARFCN), and the redirect event reporting information is used. The information indicating whether the UE records the redirection event is reported and reported. If the UE needs to record the information about the redirection event and reports the information, the redirection command message does not need to carry the redirection event report information.
步骤 S202、 UE发起小区选择过程, 选择一个小区进行驻留, 并在发起 RR连接建立时, 发生了 RRC连接建立失败;
RRC连接建立失败, 指的是 UE在 T300定时器超时之前, 仍然没有接收 到 RRC连接建立消息。 Step S202: The UE initiates a cell selection process, selects a cell to camp, and when the RR connection is initiated, an RRC connection setup fails. The RRC connection setup fails, which means that the UE still does not receive the RRC connection setup message before the T300 timer expires.
步骤 S203、 UE记录第一信息, 包括: 第一小区标识、 跟踪区 /路由区标 识、 第二小区标识、 目标频点信息、 UE 在第一' 区的标识 (例如 C-RNTI ( Cell-Radio Network Temporary Identifier , 小区无线网络临时标识)、 ShortMAC-I ( short Medium Access Control integrity protection, 短的媒体通路 控制完整保护)等信息)、 UE收到重定向命令到发生 RRC连接建立失败的时 间、 UE进行相关测量的测量结果; 其中, 对于跟踪区 /路由区的标识, 既可以 包括第一' 区的跟踪区 /路由区的标识, 也可以包括第二小区的跟踪区 /路由区 的标识。 Step S203: The UE records the first information, including: a first cell identifier, a tracking area/routing area identifier, a second cell identifier, target frequency point information, and an identifier of the UE in the first area (eg, C-RNTI (Cell-Radio) Network Temporary Identifier, information such as short medium access control integrity (short media access control integrity protection), time when the UE receives the redirect command until the RRC connection establishment fails, and the UE The measurement result of the related measurement is performed; wherein, for the identifier of the tracking area/routing area, the identifier of the tracking area/routing area of the first 'area may be included, and the identifier of the tracking area/routing area of the second cell may also be included.
小区标识包括: 小区的频点信息, 小区物理标识, 小区的位置区标识、 跟踪区标识、公共陆地移动网络( Public Land Mobile Network, PLMN )标识, 全局小区标识。小区物理标识对于 UMTS( Universal Mobile Telecommunication System, 通用移动通信系统)而言为主扰码, 对于 LTE ( Long Term Evolution, 长期演进 )则为 PCI (物理小区标识 )。 The cell identifier includes: a frequency point information of the cell, a physical identifier of the cell, a location area identifier of the cell, a tracking area identifier, a Public Land Mobile Network (PLMN) identifier, and a global cell identifier. The physical identification of the cell is the primary scrambling code for the UMTS (Universal Mobile Telecommunication System), and the PCI (physical cell identity) for the LTE (Long Term Evolution).
步骤 S204、当 UE在第三小区,发起 RRC连接建立时或者进入连接态后, 向第三小区的基站上报第一重定向指示信息, 第一重定向指示信息中包括第 一信息以及当前距离 RRC连接建立失败的间隔时间。 Step S204: When the UE initiates the RRC connection establishment or enters the connection state in the third cell, the first redirection indication information is reported to the base station of the third cell, where the first redirection indication information includes the first information and the current distance RRC. The interval at which the connection establishment failed.
步骤 S205、 第三小区的基站根据第一重定向指示信息中的第一小区的标 识, 识别出发送重定向命令的小区, 并向第一小区的基站发送第二重定向指 示信息。 可选的, 第三小区的基站还可以根据第三小区的标识和目标频点信 息, 判断出 UE是否重定向到错误的频点, 并携带在第二重定向指示信息中。 Step S205: The base station of the third cell identifies the cell that sends the redirection command according to the identifier of the first cell in the first redirection indication information, and sends the second redirection indication information to the base station of the first cell.
