When the terminal equipment falls back to the LTE network from the 5G network, the LTE registration needs to be initiated on the LTE network; in the LTE registration process, if the LTE signal quality of the cell to be registered is poor, the terminal device may measure the LTE signal and send the measurement report to the LTE network.

Detailed Description
In order to make the objects, technical solutions and advantages of the present application more apparent, the present application is described in further detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present application and are not intended to limit the present application.
It will be understood that, as used herein, the terms "first," "second," and the like may be used herein to describe various elements, but these elements are not limited by these terms. These terms are only used to distinguish one element from another. For example, the first redirection information may be referred to as second redirection information, and similarly, the second redirection information may be referred to as first redirection information, without departing from the scope of the present application. The first redirection information and the second redirection information are both redirection information, but are not the same redirection information.
Most current terminal equipment support a pseudo base station defense function. Because LTE registration requires mutual authentication between terminal equipment and an LTE cell in a bidirectional way, authentication failure of a pseudo base station causes that the terminal equipment cannot reside in a cell where the pseudo base station is located; and because the 2G cell or the 3G cell only needs one-way authentication, that is to say, when the terminal equipment registers on the 2G cell, the terminal equipment cannot distinguish the authenticity of the 2G access network equipment, so that the terminal equipment can successfully register on the 2G cell. The behavior feature of the pseudo base station may thus be that the terminal device received redirection information for redirection to the 2G cell before the LTE cell registration is completed. When the terminal device initiates a call in the 5G cell, a scene that the terminal device receives redirection information before the terminal device completes registration in the LTE network in the call establishment process is easily judged as a pseudo base station behavior by a pseudo base station defense function of the terminal device, so that call failure is caused. Therefore, it is necessary to provide a method for processing redirection information to improve the success rate of call establishment and improve user experience.
The method for processing the redirection information provided by the embodiment of the application can be applied to the technical field of communication. Fig. 1 is a schematic view of an application scenario of processing redirection information according to an embodiment of the present application. As shown in fig. 1, the scenario includes a plurality of access network devices 100 and terminal devices 200, and the access network devices 100 and the terminal devices 200 communicate via a network. The Access network device 100 may be a Base Transceiver Station (BTS) in Global System for Mobile communications (GSM) or Code Division Multiple Access (CDMA), a Base Station (NodeB, NB) in Wideband Code Division Multiple Access (WCDMA), an evolved Node B (evolved Node B, eNB or eNodeB) in LTE, a relay Station or Access point, or a Base Station in a 5G network, and the like, which are not limited herein. The communication systems supported by the access network devices 100 may be different.
It should be noted that the processing method of redirection information in the present application is not limited to solve the above technical problems, and may also be used to solve other technical problems, and the present application is not limited thereto.
The technical solution of the present application will be described in detail below with specific examples. The following several specific embodiments may be combined with each other, and details of the same or similar concepts or processes may not be repeated in some embodiments.
FIG. 2 is a flow diagram of a method for processing redirection information in one embodiment. The processing method of redirection information in this embodiment is described by taking the terminal device in fig. 1 as an example. As shown in fig. 2, the processing method of redirection information includes:
s101, according to the first redirection information sent by the first cell, a registration request is sent to the second cell.
The communication systems supported by the first cell and the second cell may be different, and the terminal device may redirect to the second cell according to the instruction sent by the first cell. For example, the first cell may be a 5G cell, and the second cell may be an LTE cell; in addition, the first cell may also be a 6 th generation mobile communication technology (abbreviated as 6G) cell, the second cell may also be a 5G cell or an LTE cell, and the communication system supported by the first cell and the second cell is not limited herein.
The first redirection information may be information indicating that the terminal device is redirected to the second cell by the first cell. The terminal device may initiate a call request on the first cell, and the first cell may send first redirection information to the terminal device to indicate the terminal device to redirect to the second cell when deployment of the first cell is not completed or the signal quality of the first cell does not meet a call requirement. The first redirection information may include identification information of the second cell, and may also include identification information of the current first cell, and the like, which is not limited herein.
The first cell may send the first redirection information to the terminal device through a radio resource control connection Release (RRC Release) message.
After receiving the RRC Release message sent by the first cell, the terminal device may extract first redirection information carried in the RRC Release message, and then send a registration request to the second cell according to an indication of the first redirection information; specifically, the terminal device may send an ATTACH Request (ATTACH Request) to the second cell, or may send a Tracking Area Update (TAU) to the second cell, which is not limited herein. The terminal device may send a registration request to the second cell through Radio Resource Control (RRC) connection. If the second cell is in a normal state, after receiving the registration request, the response information of the registration request may be sent to the terminal device.
S102, before response information of the registration request is received, prohibiting the execution of a step of triggering a second cell to send second redirection information; the second redirection message is used to instruct the terminal device to redirect to the third cell.
The terminal device may prohibit execution of the step of triggering the second cell to transmit the second redirection information until the response information of the registration request is received. The second redirection information is used to instruct the terminal device to redirect to a third cell, and the second redirection information may include identification information of the third cell and may also include identification information of the second cell, which is not limited herein.
Alternatively, the step of triggering the second cell to send the second redirection information may be sending a measurement report to the second cell. After receiving the measurement report sent by the terminal device, the second cell may determine whether to instruct the terminal device to redirect to the third cell according to the signal quality of the second cell in the measurement report; for example, if the signal quality of the second cell is too poor, the terminal device may be instructed to redirect to a third cell. That is, the terminal device may prohibit transmission of the measurement report of the second cell to the second cell until the response information of the registration request is received. The terminal device may not perform cell measurement on the second cell before receiving the response information of the registration request, so as not to generate a measurement report; or, before receiving the response information of the registration request, the terminal device may also complete cell measurement on the second cell, generate a measurement report, and set the measurement report of the second cell to a transmission-prohibited state, which is not limited herein.
The measurement report may be obtained by performing cell measurement on the cell based on the measurement configuration sent by the second cell. The measurement report may include a measurement result of the second cell, or may include a measurement result of a third cell indicated by the second cell, which is not limited herein. The measurement configuration may include a cell signal threshold corresponding to the second cell and a cell signal threshold corresponding to the third cell. Further, the terminal device may compare the measurement result with the cell signal threshold, and generate a corresponding measurement report. For example, if the signal quality of the second cell is lower than the cell signal threshold corresponding to the second cell, the terminal device may generate an a2 measurement report; if the signal quality of the third cell is higher than the cell signal threshold corresponding to the third cell, the terminal device may generate a B1 measurement report; if the signal quality of the second cell is lower than the cell signal threshold corresponding to the second cell and the signal quality of the third cell is higher than the cell signal threshold corresponding to the third cell, the terminal device may generate a B2 measurement report.
In the redirection information processing method, the terminal equipment sends a registration request to the second cell according to the first redirection information sent by the first cell; then forbidding to execute the step of triggering the second cell to send the second redirection information before receiving the response information of the registration request; wherein the second redirection message is used for establishing a call on a third cell. The terminal device forbids to execute the step of triggering the second cell to send the second redirection information before receiving the response information of the registration request, so that the situation that the second redirection information sent by the second cell is received before receiving the response information of the registration request is avoided, and the obvious difference exists between the behavior of the terminal device for identifying the pseudo base station by receiving the redirection information before the registration request is completed, so that the second cell and a third cell which is returned from the second cell cannot be identified as the pseudo base station, the call can be smoothly established on the second cell or the third cell, the success rate of call establishment is improved, and the user experience is improved.
In one embodiment, on the basis of the above embodiment, after the terminal device sends the registration request to the second cell, the measurement report may be sent according to a reception situation of response information of the registration request.
The receiving condition of the response message may include a receiving time of the response message, or may include receiving the response message or not receiving the response message, which is not limited herein. Optionally, the terminal device may determine the receiving condition of the response information according to a preset duration. The terminal equipment can determine whether response information sent by the second cell is received within a preset time length after the registration response is initiated; that is, the receiving condition of the response message may be that the response message is received within a preset time period, and the response message is not received within the preset time period.
Specifically, the terminal device may set the preset duration as a maximum duration of registration protection, and start registration protection while the terminal device sends a registration request to the second cell. And after the terminal equipment receives the response information, stopping the registration protection. If the terminal device fails to receive the response message sent by the second cell within the preset time, the registration protection may be stopped when the registration protection exceeds the preset time. The terminal device may prohibit sending the measurement report to the second cell during the time of registration protection. The preset time period may be determined by a time period required for registration of the second cell, and may be 3 seconds or 5 seconds, for example.
According to the method for processing the redirection information, the terminal equipment determines the receiving condition of the response information according to the preset time length, so that the situation that the terminal equipment cannot smoothly fall back to the third cell to establish the call under the condition that the second cell fails to respond to the registration request can be avoided, and the call establishment efficiency is improved.
In one embodiment, on the basis of the above embodiments, a specific manner in which the terminal device sends the measurement report is involved. And if the terminal equipment does not receive the response information within the preset time length, sending a measurement report to the second cell after the preset time length. Correspondingly, if the terminal equipment receives the response information within the preset time length, the terminal equipment sends a measurement report to the second cell after receiving the response information.
When the response information is not received within the preset time, the terminal device may consider that the second cell is abnormally accessed, and may not receive the response information sent by the second cell, so that the measurement report is sent after the preset time, the situation that the second redirection information is received before the response information is received can be avoided, and the second cell can be prevented from being identified as a pseudo base station. After receiving the measurement report, the second cell may determine whether the terminal device needs to be instructed to redirect to the third cell according to the measurement report, and if so, may send the second redirection information to the third cell through an RRC Release message. Further, the terminal device may receive an RRC Release message sent by the second cell; wherein, the RRC Release message carries second redirection information determined by the second cell based on the measurement report; the terminal device may establish a call on the third cell based on the second redirection message after receiving the second redirection information.
According to the processing method of the redirection information, when the time length for sending the registration request exceeds the preset time length and the response information is not received, the second cell can be prevented from being identified as the pseudo base station, the second cell can be triggered to send the second redirection information in time, and the call establishment efficiency and the call establishment success rate are improved.
Fig. 3 is a schematic flowchart of a processing method of redirection information in an embodiment, where the embodiment relates to a manner in which a terminal device improves a pseudo base station defense policy before a call is established in a third cell, and on the basis of the foregoing embodiment, as shown in fig. 3, before the terminal device establishes a call in the third cell based on a second redirection message, the method further includes:
s201, judging whether the second cell is a pseudo base station cell or not according to the current call request information of the terminal equipment and/or the historical registration information of the terminal equipment.
The current call request information may include call information associated with a current call, and may be a call request record for a terminal device to initiate a current call request; or the call establishment procedure information corresponding to the current call request information may be formed after the terminal device initiates the current call request, which is not limited herein.
Specifically, the terminal device may determine, according to the call request record, whether current call request information of the terminal device is initiated by the terminal device to the first cell; if so, determining that the second cell is not a pseudo base station cell.
The history registration information may include identification information of a cell in which the terminal device has successfully registered. The garlic planting device can search whether the cells which are successfully registered by the terminal device include the second cell in the historical registration information of the terminal device; and if so, determining that the cell is not the pseudo base station cell.
In an implementation manner, the terminal device may also determine whether the second cell is the pseudo base station cell according to the current call request information of the terminal device and the historical registration information of the terminal device in the above manner. When the terminal device initiates a call request from the first cell and successfully registers with the second cell, it may be determined that the second cell is not a pseudo base station cell.
And S202, if the second cell is not the pseudo base station cell, executing the step of establishing the call on the third cell based on the second redirection information.
According to the method for processing the redirection information, the defense strategy of the pseudo base station is improved before the terminal equipment establishes the call on the third network, so that the second cell and the third cell can be further prevented from being identified as the pseudo base station, and the call establishment success rate is further improved.
