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.
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 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 an LTE network and searches a proper GSM cell/WCDMA cell for access; 3) the UE reads the GSM cell/WCDMA cell system broadcast message and establishes a 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 invention provides a method for detecting a CSFB fallback result in a scenario that a terminal fails to sweep frequency of a specified WCDMA cell by configuring frequency point information of a wrong WCDMA cell on a network side.
In various embodiments of the present invention, in a CSFB procedure executed based on an indication information indicating that a terminal performs a voice service using a preset CSFB optimization scheme, a voice call state of the terminal in a GSM network is detected; the voice call of the terminal in the GSM network is triggered when the frequency sweep of the designated WCDMA cell fails based on the frequency point information of the designated WCDMA cell; the appointed WCDMA cell frequency point information is carried in a redirection command sent by an LTE base station; 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 frequency point information of the wrong WCDMA cell can be configured on the network side, so that the terminal detects the voice call state in the GSM network in the CSFB process under the scene of frequency sweep failure of the appointed WCDMA cell, and the fallback result of the CSFB can be finally determined, therefore, in the subsequent CSFB process, the optimization scheme can be further perfected to improve the success probability of the CSFB process, and the call experience of a user can be improved.
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 in a GSM network in a CSFB (full-service fallback) process based on indication information of a voice service performed by an indication terminal by adopting a preset CSFB optimization scheme;
here, the voice call of the terminal in the GSM network is triggered when the frequency sweep of the designated WCDMA cell fails based on the frequency point information of the designated WCDMA cell; and the appointed WCDMA cell frequency point information is carried in a redirection command sent by the LTE base station.
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 GSM 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.
Specifically, when it is detected that the terminal does not request resources to the GSM network and establishes a voice call, it is determined that the CSFB fallback fails.
When detecting that the terminal requests the resources of the GSM network and establishes the voice call, and detecting that the voice call of the terminal in the GSM network is interrupted (not continued), determining that the CSFB falls back and fails.
When the fact that the voice call of the terminal in the GSM network is not interrupted is detected, namely the terminal keeps the voice call after the voice call of the GSM network is established, after the voice call in the GSM network is finished, whether the terminal returns to the LTE network within a preset time length is detected; and when the terminal does not return to the LTE network within the preset time length, determining that the CSFB falls back to failure.
Certainly, when the terminal returns to the LTE network within the preset time period, it is determined that the CSFB fallback is successful.
The preset duration can be set according to needs. In addition, in practical application, the CSFB fallback failure may be detected by setting a timer, specifically, setting a timer, and when it is detected that the terminal does not return to the LTE network before the timer expires, determining that the CSFB fallback has failed. Correspondingly, when the terminal is detected to return to the LTE network before the timer is overtime, the CSFB fallback is determined to be successful.
Here, in practical application, whether the terminal requests a resource to the GSM network or not and establishes a voice call may be detected through related signaling; correspondingly, whether the voice call of the terminal in the GSM network is interrupted or not can be detected through related signaling, and whether the terminal returns to the LTE network within a 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 GSM network in the CSFB execution process based on the indication information of the voice service of the indication terminal by adopting the preset CSFB optimization scheme; the voice call of the terminal in the GSM network is triggered when the frequency sweep of the designated WCDMA cell fails based on the frequency point information of the designated WCDMA cell; the appointed WCDMA cell frequency point information is carried in a redirection command sent by an LTE base station; 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 process is triggered and executed when the terminal receives the paging message sent by the LTE base station, and by adopting the scheme provided by the embodiment of the invention, the frequency point information of the wrong WCDMA cell can be configured on the network side, so that the terminal can detect the voice call state in the GSM network in the CSFB process under the scene of frequency sweep failure of the appointed WCDMA cell, and finally determine the fallback result of the CSFB, therefore, in the subsequent CSFB process, the optimization scheme can be further perfected to improve the success probability of the CSFB process, and the call experience of a user is improved.
In addition, the voice call state of the terminal under the simulated network environment in the GSM 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, a WCDMA cell and a GSM cell; the LTE SIB is configured with WCDMA 1 as neighbor cell information, the GSM cell as a neighbor cell, and the LTE neighbor cell information is configured in the WCDMA SIB 18.
The abnormal scene of the application embodiment is as follows: and when the frequency point of the target WCDMA cell appointed by the network side has an error, the UE starts full-band frequency sweeping and then times out, and under the condition, the UE can still utilize the known CS resources to complete CSFB, so that the validity and the reasonability of the UE side call optimization scheme are verified.
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) and International Mobile Subscriber Identity (IMSI) attach procedure is first performed.
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.
Specifically, 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 Mobility Management Entity (MME) according to existing SGs association and MME information, where the SGsAP-PAGING-REQUEST message carries the following information: IMSI, Temporary Mobile Subscriber Identity (TMSI), Service identifier (Service indicator), 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 a 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) or a GSM/EDGE Radio Access Network (GERAN, GSM EDGE Radio Access Network) 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. The redirection command carries the wrong frequency point information of the designated WCDMA cell. As shown in fig. 4, the base station issues an R8 redirection command (rrcConnectionRelease _ R8(0)) to the UE, but the command carries the wrong frequency point information of the target WCDMA cell, and such an abnormal scenario cannot direct the terminal to fall back to the target GSM cell.
Step 202: UE can not find WCDMA cells according to the appointed frequency point information, so the frequency is swept quickly in the appointed time, at the moment, the simulation platform simulates that no available third generation mobile communication technology (3G) network resources exist, and the UE should turn to a GSM network to request CS resources to establish voice communication according to SIB configured neighbor cell information;
step 203: detecting whether the UE finds out GSM network resources and establishes a voice call, if so, executing a step 204, otherwise, indicating that CSFB fallback fails, namely, the preset CSFB optimization scheme fails;
step 204: detecting whether the UE keeps the voice call after the voice call is established, if so, executing the step 205, otherwise, indicating that the CSFB falls back to failure, namely, the preset CSFB optimization scheme fails;
step 205: and detecting whether the UE returns to the LTE network within a preset time after the call is ended, if so, indicating that the CSFB falls successfully, otherwise, indicating that the CSFB falls failed, namely, the preset CSFB optimization scheme is successful.
According to the preset CSFB optimization scheme, after the communication of the UE on the GSM network is finished, the UE should rapidly return to the LTE network.
When the UE cannot return to the LTE network within the preset duration, the UE may attempt a Routing Area Update (RAU) procedure in the WCDMA network, and this indicates that the optimization scheme fails.
