Detailed Description
So that the manner in which the features and aspects of the embodiments of the present invention can be understood in detail, a more particular description of the embodiments of the invention, briefly summarized above, may be had by reference to the embodiments, some of which are illustrated in the appended drawings.
In the technical scheme of the embodiment of the invention, an abnormal scene is simulated: when a terminal is in a Multi-RAT network (network with multiple radio access technologies) scenario and the terminal is powered on and registered in a certain radio communication network and then prepares to switch to other cells, the terminal fails to switch to an Out Of Service (OOS) state due to the fact that a network side issues an erroneous measurement configuration message.
For example, an exemplary exception scenario is: when the terminal is started and registered to the LTE network to prepare for switching to the adjacent CDMA adjacent cell, the terminal switching fails and enters an OOS state due to the fact that a network side issues an error measurement configuration message.
And aiming at the abnormal scene, a preset optimization scheme is adopted at the terminal side to execute the cell switching process, the behavior of the terminal after receiving the wrong measurement configuration message is detected, and the effectiveness and the reasonability of the optimization scheme adopted by the terminal are finally determined.
In an optional embodiment, the base station may notify the measurement configuration message to the terminal through a measConfig cell carried in an RRC connection reconfiguration (rrcconnectionreconfiguration) message, where the measurement configuration message includes an object to be measured by the terminal, a cell list, a reporting mode, a measurement identifier, an event parameter, and the like.
In the embodiment of the present invention, a network environment (referred to as a simulation network environment) may be constructed by a simulation platform, where the simulation network environment includes at least one of the following network structures: an LTE network, a TDSCDMA network, a CDMA network, and a GSM network, wherein the LTE network may be a Time Division long term evolution (TD-LTE) network or a Frequency Division duplex long term evolution (FDD-LTE) network.
Optionally, TDSCDMA neighbor cell information or CDMA neighbor cell information may be configured in a system message block (SIB) of the LTE network, for example, TDSCDMA neighbor cell information may be configured in SIB5 of the LTE network, and CDMA2000 neighbor cell information may be configured in SIB 8. FIG. 1 is a schematic diagram of a SIB8 displayed via a computer display screen.
And then, executing a cell switching process based on the constructed network environment, wherein main objects involved in the cell switching process comprise a terminal and a network, wherein the terminal can be realized by adopting a mobile phone but not limited to be realized by adopting the mobile phone, and the network can be realized by adopting a simulation platform. Here, since the network side is realized by adopting a simulation platform, the network can stably reproduce an abnormal scene, thereby verifying the feasibility and stability of the optimization scheme.
Based on the above simulated network environment, the following describes the technical solution of the embodiment of the present invention in detail.
Fig. 2 is a flowchart illustrating a method for detecting a cell handover result according to an embodiment of the present invention, where the technical solution according to the embodiment of the present invention is applied to a process in which a terminal performs cell handover by using a preset optimization scheme, where the cell handover process is a process of switching from an LTE cell to a CDMA cell; as shown in fig. 2, the method for detecting the cell switching result includes the following steps:
step 201: receiving a first attach request message sent by the terminal, wherein the first attach request message is sent by the terminal after selecting the LTE cell.
In implementation, after the terminal is powered on, the terminal may initiate a cell registration procedure to the LTE network, and the registration procedure to the LTE cell is completed.
It is noted that the precondition for performing the attach procedure between the terminal and the network is that the terminal and the network complete the RRC connection establishment procedure.
Specifically, the terminal sends an RRC connection establishment request message to the network; the network returns RRC connection establishment response information to the terminal; the terminal sends an RRC connection setup complete message to the network.
In actual implementation, after receiving a first attach request message sent by a terminal, a network can judge whether the terminal meets the requirement of accessing a first cell, and determine whether to send an attach accept message or an attach reject message to the terminal according to the judgment result;
after the network receives the first attach request message, if the network sends an attach receive message to the terminal, execute step 202; if the network sends the attachment rejection message to the terminal, the flow is ended.
Step 202: sending 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.
In an optional implementation manner, the base station sends an RRC connection reconfiguration message to the terminal; the RRC connection reconfiguration message may instruct the terminal to perform resource reconfiguration, including reconfiguring signaling bearer information and performing radio resource configuration; after the terminal performs resource reconfiguration according to the RRC connection reconfiguration message, an RRC connection reconfiguration complete message may be sent to the base station to notify the base station that the terminal completes the radio resource configuration process.
It can be understood that the above-mentioned measurement configuration message is used to inform the terminal how to perform cell measurement, that is, the terminal may perform cell measurement according to the received measurement configuration message; when the measurement configuration message is correct, the terminal can measure the adjacent cell of the LTE cell and upload a corresponding measurement report; when the measurement configuration message is wrong, the terminal cannot measure the adjacent cell of the LTE cell. For example, the wrong measurement configuration message includes a wrong Absolute Radio Frequency Channel Number (ARFCN) Channel Frequency point value, where the wrong ARFCN Channel Frequency point value is different from a preconfigured ARFCN Channel Frequency point value of a neighboring cell; at this time, if the terminal performs measurement according to the wrong ARFCN channel frequency point, a measurement report of the neighboring cell of the current cell cannot be obtained, and then cell handover cannot be initiated to the neighboring cell of the current cell.
In actual implementation, after the network receives the first attach request message sent by the terminal, a default EPS bearer may be established for the terminal, and the attach process is completed.
Here, when the default EPS bearer is established, the EPS bearer may be utilized to activate the user plane data, that is, the user plane data may be transmitted on the EPS bearer.
Step 203: and detecting the behavior of the terminal after receiving the wrong measurement configuration message to obtain a detection result.
Optionally, the behavior of the terminal after receiving the erroneous measurement configuration message may include at least one of: whether the terminal stably resides in the LTE cell is detected, whether the terminal initiates a detachment process or a redirection process is detected, and whether the terminal initiates an access request to other cells is detected.
When the method is implemented, the network can detect the behavior of the terminal after receiving the wrong measurement configuration message through a related signaling flow; for example, when the network receives a detach request (detach request) message sent by the terminal, it may be determined that the terminal initiates a detach procedure; after receiving a redirection request (RRC Connection Release) message sent by the terminal, the network may determine that the terminal starts to initiate a redirection procedure; when the network receives an attachment request message which is sent by the terminal and used for accessing other cells, the network determines that the terminal initiates an access request to other cells.
Step 204: and determining whether the terminal is successfully switched to the CDMA cell based on the detection result.
Specifically, if the terminal initiates a detach procedure or a redirect procedure within a first preset duration, it is determined that the terminal fails to successfully switch to the CDMA cell, which indicates that the optimization scheme fails.
And if the terminal does not initiate a detach process and a redirect process within a first preset time length and does not send a second attach request message within a second preset time length after the first preset time length is finished, determining that the terminal is not successfully switched to the CDMA cell, and indicating that the optimization scheme fails, wherein the second attach request message is sent after the terminal selects the CDMA cell, and the CDMA cell is a neighboring cell of the LTE cell.
And if the terminal does not initiate the detach flow and the redirect flow within the first preset time length and the terminal sends a second attach request message within a second preset time length after the first preset time length is over, determining that the terminal is successfully switched to the CDMA cell, and indicating that the optimization scheme is successful.
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, the terminal may be considered to be kept in the OOS state, and at this time, it may be determined that the terminal cannot perform cell switching in an abnormal scene; otherwise, when the terminal sends the second attach request message within a second preset duration after the first preset duration ends, the terminal may be considered to be able to leave the OOS state.
In practical application, the first preset time length and the second preset time length can be realized by setting a timer; specifically, a first timer is set, and before the first timer is overtime, whether the terminal initiates an detach flow or a redirect flow is detected; and setting a second timer, and detecting whether the terminal sends a second attachment request message or not before the second timer is overtime when the terminal is not detected to initiate a detachment process before the first timer is overtime and the terminal is not detected to initiate a redirection process, wherein the purpose of setting the timer is to avoid the detection time from being overlong.
Wherein, the duration of the timer can be set according to the requirement.
In practical application, the LTE cell and the CDMA cell are both cells located in a simulated network environment.
The method provided by the embodiment of the invention is applied to the process that the terminal executes the cell switching by adopting a preset optimization scheme, wherein the cell switching process is the process of switching from an LTE cell to a CDMA cell; firstly, receiving a first attach request message sent by the terminal, wherein the first attach request message is sent by the terminal after selecting an LTE cell; then, sending RRC connection reconfiguration information to the terminal; wherein, the RRC connection reconfiguration message carries an attach accept message and an erroneous measurement configuration message; finally, detecting the behavior of the terminal after receiving the wrong measurement configuration message to obtain a detection result; and determining whether the terminal is successfully switched to the CDMA cell based on the detection result. By adopting the scheme provided by the embodiment of the invention, the behavior of the terminal can be detected under the scene that the network issues wrong measurement configuration information to cause the terminal switching failure, so that whether the terminal can be successfully switched to a CDMA cell or not is determined, and the effectiveness and the reasonability of the optimization scheme adopted by the terminal are finally determined.
In addition, the network interacting with the terminal is a network in a simulation network environment, a simulation mode is adopted, workers do not need to go to the site, and other factors influencing detection can be removed, so that the personnel cost can be greatly reduced, and meanwhile, the influence of other factors on the detection result under the scene described by the embodiment of the invention can be eliminated.
The present application is described in further detail below with reference to an application example.
In the embodiment of the application, a simulation network environment can be constructed; the simulation network environment comprises an FDD-LTE Cell and two CDMA cells, wherein the two CDMA cells are respectively marked as a Cell0 Cell and a Cell1 Cell, and the Cell0 Cell and the Cell1 Cell are both adjacent cells of the FDD-LTE Cell; information about the Cell0 Cell is configured in the LTE SIB8, but information about the Cell0 Cell is not configured.
The method for detecting the cell residence result of the application embodiment comprises the following steps:
step A1: in the simulation network environment, the terminal is triggered to register in an FDD-LTE cell, and a default EPS bearer is established for the terminal by utilizing the simulation network environment so as to activate user plane data.
Step A2: in a simulated network environment, the signal strength of a Cell0 (the transmission power of a base station to which a Cell0 belongs) is improved; and the base station utilizing the simulated network environment sends an RRC connection reconfiguration message to the terminal so as to inform the terminal to carry out measurement preparation.
Illustratively, the base station sends the measurement configuration message of the RRC connection reconfiguration message to the terminal, where the measurement configuration message carries an incorrect ARFCN channel frequency point value, and the incorrect ARFCN channel frequency point value is higher than the ARFCN channel frequency point values of the Cell0 Cell and the Cell1 Cell.
Step A3: detecting the behavior of the terminal by using the network of the simulated network environment, and if the terminal does not cause the abnormality in the LTE network within the first preset time period (i.e. the terminal does not initiate the detach or redirect process within the first preset time period), executing step a 4; otherwise, if the terminal initiates the detach or redirect process within the first preset duration, it indicates that the optimization scheme fails.
Step A4: utilizing the behavior of the network detection terminal in the simulated network environment to judge whether the terminal performs frequency sweeping and initiates an access request to a Cell0 Cell within a second preset time after the first preset time is over; if so, verifying that the optimization scheme is successful; if not, the verification optimization scheme fails.
