具体实施方式Detailed ways
为了能够更加详尽地了解本发明实施例的特点与技术内容，下面结合附图对本发明实施例的实现进行详细阐述，所附附图仅供参考说明之用，并非用来限定本发明实施例。In order to understand the features and technical contents of the embodiments of the present invention in more detail, the implementation of the embodiments of the present invention will be described in detail below with reference to the accompanying drawings.
本发明实施例的技术方案中，模拟出一种异常场景：终端处于Multi-RAT网络(多种无线接入技术的网络)场景时，且终端开机注册到某个无线通信网络后准备向其他小区进行切换时，由于网络侧下发了错误的测量配置消息导致终端切换失败进入非服务(OOS，Out Of Service)状态。In the technical solution of the embodiment of the present invention, an abnormal scenario is simulated: when the terminal is in a Multi-RAT network (multiple radio access technology network) scenario, and the terminal is turned on and registered to a certain wireless communication network, it prepares to send data to other cells. During handover, the terminal fails to switch and enters an Out Of Service (OOS, Out Of Service) state due to an incorrect measurement configuration message sent by the network side.
例如，一种示例性地异常场景为：当终端开机注册到LTE网络准备向相邻的CDMA邻区进行切换时，由于网络侧下发了错误的测量配置消息导致终端切换失败进入OOS状态。For example, an exemplary abnormal scenario is: when the terminal is powered on and registered to the LTE network to be handed over to an adjacent CDMA neighbor, the terminal fails to switch and enters the OOS state due to an incorrect measurement configuration message sent by the network side.
针对上述异常场景，在终端侧采用预设的优化方案执行小区切换的过程，并检测终端在接收到错误的测量配置消息后的行为，最终确定终端所采用的优化方案的有效性和合理性。For the above abnormal scenario, a preset optimization scheme is used on the terminal side to perform the process of cell handover, and the behavior of the terminal after receiving the wrong measurement configuration message is detected, and the validity and rationality of the optimization scheme adopted by the terminal are finally determined.
在一种可选地实施例中，可以由基站通过RRC连接重配置(RRCConnectionReconfigurtion)消息携带的measConfig信元将测量配置消息通知给终端，在测量配置消息中包含终端需要测量的对象、小区列表、报告方式、测量标识、事件参数等。In an optional embodiment, the base station may notify the terminal of the measurement configuration message through the measConfig information element carried in the RRC connection reconfiguration (RRCConnectionReconfigurtion) message, and the measurement configuration message includes the objects that the terminal needs to measure, the cell list, Reporting methods, measurement identifiers, event parameters, etc.
本发明实施例中，可以通过仿真平台构造一个网络环境(称为仿真网络环境)，仿真网络环境至少包括以下一种网络结构：LTE网络、TDSCDMA网络、CDMA网络、GSM网络，其中，LTE网络可以是分时长期演进(TD-LTE，Time Division LTE)网络或频分双工长期演进(FDD-LTE，Frequency Division Duplexing LTE)网络。In this embodiment of the present invention, a network environment (referred to as a simulated network environment) may be constructed through a simulation platform, and the simulated network environment includes at least one of the following network structures: LTE network, TDSCDMA network, CDMA network, and GSM network, wherein the LTE network can It is a Time Division Long Term Evolution (TD-LTE, Time Division LTE) network or a Frequency Division Duplex Long Term Evolution (FDD-LTE, Frequency Division Duplexing LTE) network.
可选地，可以在所述LTE网络的系统消息块(SIB)中配置TDSCDMA邻区信息或CDMA的邻区信息，例如，可以在LTE网络的SIB5中配置TDSCDMA邻区信息，在SIB8中配置CDMA2000的邻区信息。图1为通过计算机显示屏显示SIB8的示意图。Optionally, TDSCDMA neighbor information or CDMA neighbor information may be configured in a system message block (SIB) of the LTE network. For example, TDSCDMA neighbor information may be configured in SIB5 of the LTE network, and CDMA2000 may be configured in SIB8. neighborhood information. Figure 1 is a schematic diagram of displaying SIB8 through a computer display screen.
而后，基于构造的网络环境执行小区切换过程，在小区切换过程中涉及到的主要对象包括终端和网络，其中，终端可以但不局限于采用手机来实现，网络可以采用仿真平台来实现。这里，由于网络侧采用仿真平台来实现，因而这种网络能够稳定复现异常场景，从而验证优化方案的可行性以及稳定性。Then, the cell handover process is performed based on the constructed network environment. The main objects involved in the cell handover process include the terminal and the network. The terminal can be implemented by but not limited to a mobile phone, and the network can be implemented by an emulation platform. Here, since the network side is implemented by a simulation platform, this kind of network can stably reproduce abnormal scenarios, thereby verifying the feasibility and stability of the optimization scheme.
基于上述的仿真网络环境，以下对本发明实施例的技术方案做详细描述。Based on the above-mentioned simulated network environment, the technical solutions of the embodiments of the present invention are described in detail below.
图2为本发明实施例小区切换结果的检测方法的流程示意图，本发明实施例的技术方案应用于终端采用预设的优化方案执行小区切换的过程中，所述小区切换的过程为从LTE小区切换至CDMA小区的过程；如图2所示，所述小区切换结果的检测方法包括以下步骤：FIG. 2 is a schematic flowchart of a method for detecting a cell handover result according to an embodiment of the present invention. The technical solution of the embodiment of the present invention is applied to a process in which a terminal adopts a preset optimization scheme to perform a cell handover, and the cell handover process is from an LTE cell The process of switching to a CDMA cell; as shown in Figure 2, the detection method of the cell switching result includes the following steps:
步骤201：接收所述终端发送的第一附着请求消息，其中，所述第一附着请求消息是所述终端选择所述LTE小区后发送的。Step 201: Receive a first attach request message sent by the terminal, where the first attach request message is sent after the terminal selects the LTE cell.
在实施时，可以在终端开机后，由终端向LTE网络发起小区注册流程，已完成到LTE小区的注册过程，在该小区注册流程中，终端可以发送第一附着请求消息。In implementation, the terminal may initiate a cell registration process to the LTE network after the terminal is powered on, and the registration process to the LTE cell has been completed. In the cell registration process, the terminal may send a first attach request message.
值得注意的是，终端和网络之间执行附着过程的前提是，终端与网络完成了RRC连接建立过程。It is worth noting that the premise of performing the attach process between the terminal and the network is that the terminal and the network have completed the RRC connection establishment process.
具体地，终端向网络发送RRC连接建立请求消息；网络向终端返回RRC连接建立响应消息；终端向网络发送RRC连接建立完成消息。Specifically, the terminal sends an RRC connection establishment request message to the network; the network returns an RRC connection establishment response message to the terminal; and the terminal sends an RRC connection establishment complete message to the network.
在实际实施时，当网络接收到终端发送的第一附着请求消息后，可以判断终端是否符合接入第一小区的要求，根据判断结果，确定向终端发送附着接受消息还是向终端发送附着拒绝消息；In actual implementation, after the network receives the first attach request message sent by the terminal, it can determine whether the terminal meets the requirements for accessing the first cell, and according to the judgment result, determine whether to send an attach accept message to the terminal or send an attach reject message to the terminal ;
当网络接收到第一附着请求消息后，如果网络向终端发送附着接收消息，则执行步骤202；如果网络向终端发送附着拒绝消息，则结束流程。After the network receives the first attach request message, if the network sends an attach reception message to the terminal,
步骤202：向所述终端发送RRC连接重配置消息；其中，所述RRC连接重配置消息中携带有附着接受消息和错误的测量配置消息。Step 202: Send an RRC connection reconfiguration message to the terminal; wherein, the RRC connection reconfiguration message carries an attach accept message and an erroneous measurement configuration message.
一种可选的实施方式是，由基站向终端发送RRC连接重配置消息；RRC连接重配置消息可以指示终端进行资源重配置，包括重配置信令承载信息和进行无线资源配置；在终端按照RRC连接重配置消息进行资源重配置后，可以向基站发送RRC连接重配置完成消息，以通知基站终端完成无线资源配置过程。An optional implementation is that the base station sends an RRC connection reconfiguration message to the terminal; the RRC connection reconfiguration message can instruct the terminal to perform resource reconfiguration, including reconfiguration signaling bearer information and radio resource configuration; After the connection reconfiguration message performs resource reconfiguration, an RRC connection reconfiguration complete message may be sent to the base station to notify the base station terminal to complete the radio resource configuration process.
可以理解的是，上述记载的测量配置消息用于通知终端如何进行小区测量，也就是说，终端可以按照接收到测量配置消息进行小区测量；当测量配置消息正确时，终端可以对LTE小区的邻区进行测量，并上传相应的测量报告；当测量配置消息错误时，终端不能对LTE小区的邻区进行测量。例如，错误的测量配置消息中包含错误的绝对无线频道编号(ARFCN，Absolute Radio Frequency Channel Number)信道频点值，该错误的ARFCN信道频点值不同于预先配置的邻区的ARFCN信道频点值；此时，如果终端按照该错误的ARFCN信道频点进行测量，则不能得到当前小区的邻区的测量报告，进而不能向当前小区的邻区发起小区切换。It can be understood that the measurement configuration message recorded above is used to inform the terminal how to perform cell measurement, that is, the terminal can perform cell measurement according to the received measurement configuration message; when the measurement configuration message is correct, the terminal can measure the neighbors of the LTE cell. The terminal performs measurement on the LTE cell and uploads the corresponding measurement report; when the measurement configuration message is incorrect, the terminal cannot measure the adjacent cells of the LTE cell. For example, the wrong measurement configuration message contains the wrong Absolute Radio Frequency Channel Number (ARFCN, Absolute Radio Frequency Channel Number) channel frequency value, and the wrong ARFCN channel frequency value is different from the pre-configured ARFCN channel frequency value of the neighboring cell. ; At this time, if the terminal performs measurement according to the wrong ARFCN channel frequency, it cannot obtain the measurement report of the adjacent cell of the current cell, and cannot initiate cell handover to the adjacent cell of the current cell.
在实际实施时，当网络接收终端发送的第一附着请求消息后，还可以为所述终端建立默认EPS承载，已完成附着过程。In actual implementation, after the network receives the first attach request message sent by the terminal, it can also establish a default EPS bearer for the terminal, and the attach process has been completed.
这里，在建立默认EPS承载，可以利用EPS承载激活用户面数据，也就是说，可以在EPS承载上传输用户面数据。Here, when the default EPS bearer is established, the user plane data can be activated by using the EPS bearer, that is, the user plane data can be transmitted on the EPS bearer.
步骤203：检测所述终端在接收到错误的测量配置消息后的行为，得到检测结果。Step 203: Detect the behavior of the terminal after receiving the wrong measurement configuration message, and obtain a detection result.
可选地，检测终端在接收到错误的测量配置消息后的行为可以包括以下至少一项：检测终端是否稳定驻留于LTE小区、检测终端是否发起去附着流程或重定向流程、检测终端是否发起向其他小区的接入请求。Optionally, detecting the behavior of the terminal after receiving the wrong measurement configuration message may include at least one of the following: detecting whether the terminal stably camps on the LTE cell, detecting whether the terminal initiates a detachment procedure or a redirection procedure, detecting whether the terminal initiates a detachment procedure or a redirection procedure Access requests to other cells.
在实施时，网络可以通过相关信令流程检测终端在接收到错误的测量配置消息后的行为；例如，网络接收到终端发送的去附着请求(detach request)消息时，可以确定终端发起去附着流程；网络接收到终端发送的重定向请求(RRC Connection Release)消息后，可以确定终端开始发起重定向流程；网络接收到终端发送的用于接入其他小区的附着请求消息时，确定终端发起向其他小区的接入请求。During implementation, the network can detect the behavior of the terminal after receiving the wrong measurement configuration message through the relevant signaling process; for example, when the network receives the detach request message sent by the terminal, it can determine that the terminal initiates the detachment process. ; After the network receives the redirection request (RRC Connection Release) message sent by the terminal, it can determine that the terminal starts to initiate a redirection process; when the network receives the attachment request message sent by the terminal for accessing other cells, it determines that the terminal initiates a redirection process to other cells. cell access request.
步骤204：基于检测结果确定所述终端是否成功切换至所述CDMA小区。Step 204: Determine whether the terminal is successfully handed over to the CDMA cell based on the detection result.
具体地，如果所述终端在第一预设时长内发起去附着流程或重定向流程，确定所述终端未能成功切换至所述CDMA小区，说明优化方案失败。Specifically, if the terminal initiates a detachment process or a redirection process within the first preset time period, and it is determined that the terminal fails to be successfully handed over to the CDMA cell, it means that the optimization solution fails.
如果所述终端在第一预设时长内未发起去附着流程且未发起重定向流程，且所述终端在第一预设时长结束的第二预设时长内未发送第二附着请求消息，确定所述终端未能成功切换至所述CDMA小区，说明优化方案失败，其中，所述第二附着请求消息是所述终端选择所述CDMA小区后发送的，所述CDMA小区为所述LTE小区的邻区。If the terminal does not initiate the detachment procedure and does not initiate the redirection procedure within the first preset duration, and the terminal does not send the second attach request message within the second preset duration after the first preset duration ends, determine The terminal fails to switch to the CDMA cell successfully, indicating that the optimization scheme fails, wherein the second attach request message is sent by the terminal after selecting the CDMA cell, and the CDMA cell is the LTE cell. Neighborhood.
如果所述终端在第一预设时长内未发起去附着流程且未发起重定向流程，且所述终端在第一预设时长结束的第二预设时长内发送第二附着请求消息，确定所述终端成功切换至所述CDMA小区，说明优化方案成功。If the terminal does not initiate the detachment procedure and does not initiate the redirection procedure within the first preset duration, and the terminal sends the second attach request message within the second preset duration after the first preset duration ends, it is determined that the The terminal is successfully handed over to the CDMA cell, indicating that the optimization scheme is successful.
可以理解的是，当终端在第一预设时长结束的第二预设时长内未发送第二附着请求消息时，可以认为终端保持在OOS状态，此时可以确定终端不能在异常场景中进行小区切换；反之，当终端在第一预设时长结束的第二预设时长内发送第二附着请求消息时，可以认为终端能够脱离OOS状态。It can be understood that, when the terminal does not send the second attach request message within the second preset duration after the first preset duration ends, it can be considered that the terminal remains in the OOS state, and at this time it can be determined that the terminal cannot perform cell operations in an abnormal scenario. On the other hand, when the terminal sends the second attach request message within the second preset duration after the first preset duration ends, it can be considered that the terminal can leave the OOS state.
实际应用中，所述第一预设时长和第二预设时长可以通过设置定时器的方式实现；具体地，设置第一定时器，在所述第一定时器超时前检测所述终端是否发起去附着流程或重定向流程；设置第二定时器，当在所述第一定时器超时前未检测到所述终端发起去附着流程，且未检测到所述终端发起重定向流程时，在所述第二定时器超时前检测所述终端是否发送第二附着请求消息，其中，设置定时器的目的是避免检测的时间过长。In practical applications, the first preset duration and the second preset duration can be implemented by setting a timer; specifically, a first timer is set, and before the first timer expires, it is detected whether the terminal initiates A detachment process or a redirection process; a second timer is set, and when it is not detected that the terminal initiates a detachment process before the first timer expires, and it is not detected that the terminal initiates a redirection process, the Before the second timer expires, it is detected whether the terminal sends the second attach request message, wherein the purpose of setting the timer is to avoid the detection time being too long.
其中，定时器的时长可以根据需要设置。The duration of the timer can be set as required.
