Detailed Description
So that the manner in which the features and elements of the present invention can be understood in detail, a more particular description of the invention, briefly summarized above, may be had by reference to embodiments, some of which are illustrated in the appended drawings.
Under normal conditions, the terminal with the CSFB function can search the LTE network when being started, complete the joint registration of the LTE/2G/3G network and carry out voice calling and called.
The CSFB procedure comprises three phases: 1) the UE initiates a call (corresponding to MO) in the LTE network or receives a paging (corresponding to MT); 2) the UE falls back under the guidance of the LTE network and searches a proper 2G network cell or a proper 3G network cell for access; 3) and the UE reads the system broadcast message of the 2G network cell or the 3G network cell and establishes the voice call.
With the continuous expansion of the LTE base station scale and the network quitting and re-cultivation of some old GSM/TDSCDMA base stations, the configuration of the original network deployment on the signaling side of the base station is not updated in real time, and the configuration information issued by the network to the UE is inconsistent with the actual deployment situation, so that various abnormal situations, such as unavailable connection, failed repeated connection, etc., occur in the voice call across systems (inter rat) such as CSFB.
In order to solve the call problem caused by the incompatible situation of network deployment, various optimization means are adopted by terminal manufacturers to improve the call experience, and in order to verify the rationality of the CSFB optimization scheme, it is necessary to detect the CSFB process in an abnormal scene so as to improve the CSFB optimization scheme in a targeted manner.
The CSFB fallback scheme adopts a 3GPP R8 redirection fallback scheme, and during a CSFB deployment process, a CSFB procedure is probabilistically abnormal due to a problem of parameter configuration. Therefore, the embodiment of the present invention provides a method for detecting a CSFB fallback result when an EVDO cell configured on a network side is out of service or weak.
In various embodiments of the present invention, in a CSFB procedure executed based on indication information indicating that a terminal employs a preset CSFB optimization scheme for voice service, a voice call state of the terminal in a 1xRTT network is detected; the voice call of the terminal under the 1xRTT network is triggered based on specific conditions, wherein the specific conditions comprise that: carrying EVDO cell frequency point information in a redirection command sent by an LTE base station to the terminal by mistake, and receiving an EVDO cell signal with the signal intensity smaller than a set threshold value by the terminal based on the EVDO cell frequency point information; judging whether the CSFB falls back successfully or not by using the detected voice call state; the indication information is carried in an attachment acceptance message sent by the LTE base station to the terminal; the attachment acceptance message is sent by the LTE base station after the terminal sends an attachment request message to the LTE base station; the CSFB procedure is triggered to be executed when the terminal receives the paging message sent by the LTE base station.
By adopting the scheme provided by the embodiment of the invention, the voice call state under the 1xRTT network in the CSFB process can be detected in the scene when the EVDO cell configured at the network side has no service or weak signals, so that the fallback result of the CSFB can be finally determined, and thus, in the subsequent CSFB process, the optimization scheme can be further perfected to improve the success probability of the CSFB process, so as to improve the call experience of users.
Fig. 1 is a schematic flow chart of a method for detecting a fallback result of a CSFB provided in an embodiment of the present invention, and as shown in fig. 1, the method for detecting a fallback result of a CSFB includes the following steps:
step 101: detecting a voice call state of a terminal under a single carrier wireless transmission technology 1xRTT network in a CSFB execution process based on indication information indicating that the terminal adopts a preset CSFB optimization scheme to perform voice service;
here, the voice call of the terminal under the 1xRTT network is triggered based on specific conditions, including: and carrying EVDO cell frequency point information in a redirection command sent to the terminal by the LTE base station in an error manner, and receiving an EVDO cell signal with the signal intensity smaller than a set threshold value by the terminal based on the EVDO cell frequency point information.
The indication information is carried in an attachment acceptance message sent by the LTE base station to the terminal; the attachment acceptance message is sent by the LTE base station after the terminal sends an attachment request message to the LTE base station.
The CSFB procedure is triggered to be executed when the terminal receives the paging message sent by the LTE base station.
In practical application, a network environment applied to the embodiment of the invention can be constructed in a laboratory simulation mode, that is, the scene where the terminal is located in the embodiment of the invention is obtained in a simulation mode, so that on one hand, a worker does not need to go to a field for detection, and therefore, the cost of the worker can be reduced; on the other hand, the scene of the site may include other factors, so as to affect the detection result, so that the simulation network according to the embodiment of the present invention can stably reproduce the CSFB abnormal scene occurring in the scene of the site, and can eliminate the influence of other factors on the detection result in the scene described in the embodiment of the present invention.
Based on this, in some embodiments, a voice call state of the terminal in the 1xRTT network in the emulated network environment is detected.
Step 102: and judging whether the CSFB falls back successfully or not by using the detected voice call state.
Optionally, when it is detected that the terminal does not initiate an access request to the 1xRTT network within a first preset duration and establishes a voice call based on the 1xRTT network, it is determined that the CSFB fallback fails.
When detecting that the terminal does not initiate an access request of a 1xRTT network within a first preset duration and establish a voice call based on the 1xRTT network, and when the terminal enters an Out of Service (OoS) state or continuously sweeps an EVDO cell, determining that the CSFB falls back and fails.
Optionally, when it is detected that the voice call of the terminal in the 1xRTT network is interrupted, it is determined that the CSFB fallback fails.
Optionally, when it is detected that the voice call of the terminal in the 1xRTT network is not interrupted, that is, the terminal maintains the voice call after the voice call of the 1xRTT network is established, after the voice call in the 1xRTT network is ended, it is detected whether the terminal returns to the LTE network within a second preset duration; and when the terminal does not return to the LTE network within the second preset time, determining that the CSFB falls back to failure.
Certainly, when the terminal returns to the LTE network within the second preset duration, it is determined that the CSFB fallback is successful.
The first preset time and the second preset time can be set according to needs.
Here, in actual application, whether the terminal requests a resource to the 1xRTT network or not can be detected through related signaling, and a voice call is established; correspondingly, whether the voice call of the terminal in the 1xRTT network is interrupted or not can be detected through related signaling, and whether the terminal returns to the LTE network within a second preset time length or not can be detected through related signaling.
The method provided by the embodiment of the invention detects the voice call state of the terminal in the 1xRTT network in the CSFB execution process based on the indication information of the voice service performed by the indication terminal by adopting the preset CSFB optimization scheme; the voice call of the terminal under the 1xRTT network is triggered based on specific conditions, wherein the specific conditions comprise that: carrying EVDO cell frequency point information in a redirection command sent by an LTE base station to the terminal by mistake, and receiving an EVDO cell signal with the signal intensity smaller than a set threshold value by the terminal based on the EVDO cell frequency point information; judging whether the CSFB falls back successfully or not by using the detected voice call state; the indication information is carried in an attachment acceptance message sent by the LTE base station to the terminal; the attachment acceptance message is sent by the LTE base station after the terminal sends an attachment request message to the LTE base station; the CSFB procedure is triggered and executed when the terminal receives a paging message sent by the LTE base station; by adopting the scheme provided by the embodiment of the invention, the voice call state under the 1xRTT network in the CSFB process can be detected in the scene when the EVDO cell configured at the network side has no service or weak signals, so that the fallback result of the CSFB can be finally determined, and thus, in the subsequent CSFB process, the optimization scheme can be further perfected to improve the success probability of the CSFB process, so as to improve the call experience of users.
In addition, the voice call state of the terminal under the simulated network environment in the 1xRTT network is detected, 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 invention is described in more detail below with reference to an application example.
In the embodiment of the application, a network environment is constructed through a simulation platform, and the network environment comprises a Frequency Division Duplex (FDD) -LTE cell, an EVDO cell and a 1xRTT cell; and configuring EVDO as the cell information of the neighboring cell in the LTE SIB.
The abnormal scene of the application embodiment is as follows: the EVDO 3G cell appointed by the network side is out of service, and the UE automatically searches the 2G 1xRTT network of the adjacent cell to finish the validity and the rationality of the CSFB scheme.
As shown in fig. 2, the method for detecting a CSFB fallback result in the present application embodiment includes the following steps:
step 200: UE registers on an LTE cell and carries out an attachment process;
specifically, the UE is an MT, and after the UE is powered on, an Evolved Packet System (EPS)/International Mobile Subscriber Identity (IMSI) attach procedure is executed first.
In the process, the UE is triggered to send an Attach Request message (Attach Request) to the LTE base station, and an Attach Accept message (Attach Accept) sent by the LTE base station is received, wherein the Attach Accept message carries indication information for indicating the terminal to adopt a preset CSFB optimization scheme for voice service. Fig. 3 is a first schematic diagram of an emulation code according to an embodiment of the present invention, where: IMS voice over PS (V) ═ Not supported (0), and represents the instruction information.
Step 201: the network side triggers the MT CSFB flow, the network side sends a Paging message (Paging) to the UE, and the CSFB flow is started;
here, in practical application, the MO needs to initiate a call to the MT first, and then the MT receives the paging message sent by the network side.
Illustratively, after receiving an initial address REQUEST (IAM) incoming message, a Mobile Switching Center (MSC) in the network sends an SGsAP-PAGING-REQUEST message to an MME according to existing SGs association and Mobility Management Entity (MME) information, where the SGsAP-PAGING-REQUEST message carries the following information: IMSI, Temporary Mobile Subscriber Identity (TMSI), service identifier (Serviceindicator), calling number, location area information.
After receiving the message, the MME sends a Paging message to the base station, and the base station initiates a Paging flow of an air interface. UE establishes connection and sends Extended Service Request message to MME, MME sends SGsAP-Service-Request message to MSC, MSC receives the message, and MSC does not resend paging Request message to MME. In order to avoid the overlong waiting time of the calling party in the call connection process, the MSC receives the SGs Service Request message containing the idle state indication and firstly informs the calling party that the calling party is in the connection process. The MME sends an Initial UE Context Setup message to the base station, wherein the Initial UE Context Setup message carries a CS feedback Indicator, and the CS feedback Indicator is used for indicating that the base station UE needs to fall back to a UMTS Terrestrial Radio Access Network (UTRAN)/GSM/EDGE Radio Access Network (GSM EDGE Radio Access Network, GERAN) due to CSFB service.
In the attach procedure, the UE receives an LTE _ RRCConnectionRelease signaling, i.e., a redirection command, sent by the LTE base station. And carrying frequency point information of the target EVDO 3G cell in the redirection command. As shown in fig. 4, the base station issues an R8 redirection command (rrcConnectionRelease _ R8(0)) to the UE, where the command carries the frequency point information of the target EVDO 3G cell.
Step 202: the signal strength of the EVDO cell signal is controlled to be reduced.
Here, when the UE determines that the signal strength of the network signal received by the EVDO cell is smaller than the set threshold, the UE cannot perform the voice call in the EVDO network, and at this time, the UE needs to initiate an access request of the 1xRTT network within a first preset duration and establish the voice call based on the 1xRTT network.
In practical implementation, an EVDO cell signal can be simulated through the simulation platform, so that the simulation of an EVDO cell weak signal is realized;
when determining that the signal intensity of the network signal received by the EVDO cell is smaller than the set threshold, the UE may switch to the 1xRTT network to request the CS resource to establish the voice call according to the pre-configured neighboring cell information.
Step 203: detecting whether the UE finds out a 1xRTT network resource within a first preset duration and establishing a voice call, if so, executing a step 204, otherwise, indicating that the CSFB fallback fails, namely, the preset CSFB optimization scheme fails;
step 204: and detecting whether the UE can return to the LTE network within a second preset time after the call is ended, if so, indicating that the CSFB falls successfully, otherwise, indicating that the CSFB falls failed.
According to the preset CSFB optimization scheme, after the UE finishes the network call in the 1xRTT, the UE should rapidly return to the LTE network.
When the UE cannot return to the LTE network within the second preset duration, the UE may attempt a Route Area Update (RAU) procedure in the EVDO network, and at this time, it indicates that the optimization scheme fails.
