The embodiments of the present invention are described in detail below with reference to the accompanying drawings.

Under normal circumstances, the terminal with CSFB function can search for LTE network and complete The LTE/2G network is jointly registered and capable of voice calling and called.

The CSFB process consists of three phases: 1) the UE initiates a call (corresponding to MO) on the LTE network, or receives a page (corresponding to the MT); 2) the UE falls back under the guidance of the LTE network and searches for a suitable GSM cell/wideband code score The multiple access WCDMA cell accesses; 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 and the retreat and re-farming of some old GSM/TD-SCDMA base stations, the configuration of the original network deployed on the base station signaling side is not updated in real time, and the network is sent to the UE. The configuration information is inconsistent with the actual deployment situation, which leads to various abnormal situations such as CSFB inter-system (InterRAT) voice calls, such as failure to connect, repeated connection failure, and the like.

In order to solve the call problem caused by such network deployment incompatibility, various terminal manufacturers have adopted various optimization methods to improve the call experience. To verify the rationality of the CSFB optimization scheme, it is necessary to perform the CSFB process in the abnormal scenario. Detecting in order to improve the CSFB optimization scheme in a targeted manner.

The CSFB fallback scheme adopts the 3GPP R8 redirection fallback scheme. During the CSFB deployment process, the problem of parameter configuration will probabilistically cause the CSFB process to be abnormal. To this end, the embodiment of the present invention provides a method for detecting a CSFB fallback result in a scenario in which a WCDMA cell data request access failure is specified by a network side.

In various embodiments of the present invention, in the process of performing CSFB based on indication information indicating that the terminal performs voice service by using a preset CSFB optimization scheme, detecting a packet initiated by the terminal under the wideband code division multiple access WCDMA network The failure information of the PS domain access authentication process is exchanged; the failure information of the PS domain access authentication process is initiated by the terminal after the voice call establishment based on the circuit switched CS domain in the WCDMA network is completed.

The solution provided by the embodiment of the present invention can detect the voice call state in the WCDMA network in the CSFB process in the scenario that the PS domain access authentication process fails after the terminal falls back to the WCDMA cell specified by the network side, thereby finally determining the CSFB. The result of the fallback, in this way, in the subsequent process of CSFB, the optimization scheme can be further improved to improve the probability of success of the CSFB process, so as to improve the user's calling experience.

FIG. 1 is a schematic flowchart of a CSFB fallback result detecting method according to an embodiment of the present invention. As shown in FIG. 1, the CSFB fallback result detecting method includes the following steps:

Step 101: In the process of performing CSFB based on the indication information indicating that the terminal performs the voice service by using the preset CSFB optimization scheme, detecting that the packet switching PS domain access authentication process initiated by the terminal in the WCDMA network fails information;

Here, the failure information of the PS domain access authentication process is that the authentication failure of the PS domain access authentication process initiated by the terminal after the completion of the voice call establishment based on the circuit switched CS domain in the WCDMA network is completed. information.

That is, the scenario in which the terminal is located in the embodiment of the present invention is obtained through simulation, and the processing is performed on the one hand. The staff does not need to go to the site for testing, which can reduce the cost of personnel; on the other hand, the scene on the scene may contain other factors, thus Affecting the detection result, the simulation network of the embodiment of the present invention can stably reproduce the CSFB abnormal scene that occurs in the field network, and can eliminate the influence of other factors on the detection result in the scenario described in the embodiment of the present invention.

Based on this, in some embodiments, the voice call state of the terminal in the WCDMA network in the simulated network environment is detected.

Step 102: Detect a voice call state of the terminal in a WCDMA network in a state in which the PS domain access authentication process fails.

Step 103: Determine whether the CSFB is successfully dropped based on at least the voice call state.

In a specific embodiment, when it is determined that the voice call of the terminal in the WCDMA network is interrupted (ie, not continued) based on the voice call state, the CSFB fallback is determined to be failed.

In another specific embodiment, after the end of the voice call in the WCDMA network, detecting whether the terminal returns to the LTE network within a preset duration; when the terminal does not return to the LTE network within the preset duration , determining that the CSFB falls back. Here, in an actual application, the preset duration may be set as needed.

In a specific scenario, when it is detected that the voice call of the terminal in the WCDMA network is not interrupted, that is, the terminal keeps a voice call after the voice call of the WCDMA network is established, the voice in the WCDMA network After the call ends, it is detected whether the terminal returns to the LTE network within a preset duration; when the terminal does not return to the LTE network within the preset duration, it is determined that the CSFB fallback fails. Correspondingly, when the terminal returns to the LTE network within the preset duration, it is determined that the CSFB fallback is successful. That is, when it is detected that the voice call of the terminal in the WCDMA network is not interrupted, that is, the terminal keeps a voice call after the voice call of the WCDMA network is established, and the voice call ends in the WCDMA network. After the terminal returns to the LTE network within the preset duration, it is determined that the CSFB is successfully dropped.

In another specific embodiment, detecting that the terminal initiates an attach request, determining the CSFB Fallback failed.

In another specific embodiment, after the end of the voice call in the WCDMA network, detecting that the terminal performs a routing area update RAU procedure in the WCDMA network, determining that the CSFB fallback fails.

Here, in actual application, it is possible to detect whether the terminal's voice call in the WCDMA network is interrupted by related signaling. Similarly, the related signaling is used to detect whether the terminal returns to the LTE network within a preset time period. Correlated signaling to determine whether the terminal is at the end of a voice call, performing a RAU procedure in the WCDMA network, and determining that the requesting PS resource fails by corresponding signaling (eg, due to a failure of the PS domain access authentication procedure) After the PS domain resource request fails, an attach request is initiated.

In this way, the method provided by the embodiment of the present invention detects a packet initiated by the terminal in the wideband code division multiple access WCDMA network in the process of performing CSFB based on the indication information indicating that the terminal performs the voice service by using the preset CSFB optimization scheme. The failure information of the PS domain access authentication process is exchanged; the failure information of the PS domain access authentication process is initiated by the terminal after the voice call establishment based on the circuit switched CS domain in the WCDMA network is completed.

The solution provided by the embodiment of the present invention can detect the voice call state in the WCDMA network in the CSFB process in the scenario that the PS domain access authentication process fails after the terminal falls back to the WCDMA cell specified by the network side, thereby finally determining the CSFB. The result of the fallback, in this way, in the process of subsequent CSFB, the optimization scheme can be further improved to improve the probability of success of the CSFB process, so as to enhance the call of the user. Call the experience.

In addition, detecting the voice call state of the terminal under the WCDMA network in the simulated network environment, the simulation method does not require the staff to go to the site, and other factors affecting the detection can be removed, thereby greatly reducing the personnel cost, and simultaneously The influence of other factors on the detection result in the scenario described in the embodiment of the present invention can be eliminated.

The present invention will be further described in detail below with reference to an application embodiment.

In this application embodiment, a network environment is constructed by using a simulation platform, including a frequency division duplex (FDD)-LTE cell and a WCDMA cell. Among them, WCDMA 1 is configured as neighbor cell information in the LTE SIB, and LTE is configured in the WCDMA SIB18. Neighbor cell information.

The abnormal scenario of the application embodiment is that the RAU authentication process fails after the CSFB falls back to the designated WCDMA cell because the terminal does not open the 3G data service, and the terminal can still complete the CSFB and complete the voice call by using the CS resource in this case. To verify the validity and rationality of the terminal side call optimization scheme.

The detection method of the fallback result of the CSFB of this application embodiment, as shown in FIG. 2, includes the following steps:

Step 201: The UE registers with the LTE cell to perform an attach procedure.

Specifically, the UE is an MT, and after the UE is powered on, the Evolved Packet System (EPS)/International Mobile Subscriber Identification Number (IMSI) attach procedure is first executed.

The method includes: triggering the UE to send an attach request message (Attach Request) to the LTE base station, and receiving an attach accept message sent by the LTE base station, where the attach accept message is carried to indicate the terminal The preset CSFB optimization scheme is used to indicate the voice service. FIG. 3 is a first schematic diagram of an emulation code according to an embodiment of the present invention, wherein: IMS voice over PS(V)=Not supported(0), representing the indication information.

Step 202: The network side triggers the MT CSFB process, and the network side sends a paging message (Paging). Give the UE, start the CSFB process;

Specifically, after receiving the initial address request (IAM) incoming message, the mobile services switching center (MSC) in the network sends the SGsAP-PAGING-REQUEST message according to the existing SGs association and Mobility Management Entity (MME) information. To the MME, the SGsAP-PAGING-REQUEST message carries the following information: IMSI, Temporary Mobile Subscriber Identity (TMSI), Service Indicator, Calling Number, and Location Area Information.

After receiving the message, the MME sends a paging message to the base station, and the base station initiates an air interface Paging process. The UE establishes a connection and sends an Extended Service Request message to the MME. The MME sends an SGsAP-SERVICE-REQUEST message to the MSC. The MSC receives the message and does not resend the paging request message to the MME. To avoid the call waiting time being too long during the call connection process, the MSC receives the SGs Service Request message containing the idle state indication, first notifying that the calling call is in the process of being connected. The MME sends an Initial UE Context Setup message to the base station. Here, the Initial UE Context Setup message carries a CS Fallback Indicator, and the CS Fallback Indicator is used to indicate that the base station UE needs to fall back to the UMTS Terrestrial Radio Access Network due to the CSFB service requirement (UTRAN, UMTS Terrestrial Radio Access Network). ) / GSM / EDGE Radio Access Network (GERAN, GSM EDGE Radio Access Network).

In the attaching process, the UE receives the LTE_RRCConnectionRelease signaling sent by the LTE base station, that is, the redirect command. The redirection command carries the frequency point information of the designated WCDMA cell, that is, the frequency point information of the target WCDMA cell.

As shown in FIG. 4, the base station sends an R8 redirection command (rrcConnectionRelease_R8(0)) to the UE, where the command carries the frequency information of the target WCDMA cell, so that the UE can be connected based on the frequency information carried in the R8 redirection command. Into the target WCDMA cell.

Step 203: After the UE accesses the WCDMA cell according to the specified frequency point information (that is, the frequency information of the target WCDMA cell), the RRC Request is initiated, and the network side sends the CS call resource. The source, the radio access bearer (RAB) setup, the voice call is established; at this time, the simulation platform simulation: the PS domain access authentication process fails, the terminal cannot obtain the PS domain resource, and the subsequent RAU process cannot be completed.

At this time, it is checked whether the voice call state of the CS domain is affected by the UE in this case; whether the FastReturn can successfully return to the LTE network after the call ends, that is, whether the LTE network can be returned within a preset time.

specifically:

Step 204: Check whether the voice call state of the CS domain is not affected by the UE in this case, that is, whether the UE can maintain the voice call in this case, and if yes, execute step 205; otherwise, the CSFB fallback fails. , that is, the default CSFB optimization scheme fails;

Step 205: Detect whether the UE returns to the LTE network within a preset time period after the call ends. If yes, the CSFB fallback is successful. Otherwise, the CSFB fallback fails.

Step 206: Determine whether the UE initiates an attach request after the RAU requests the PS authentication failure; if yes, the CSFB fallback fails. Otherwise, the CSFB falls back successfully.

In an actual application, the execution steps of step 204 and step 206 may be reversed, and the execution order of

steps

204 and 206 is not limited in this embodiment.

When the UE cannot return to the LTE network within the preset duration, the UE may attempt to perform the RAU procedure in the WCDMA network, indicating that the optimization scheme fails. That is, it is detected whether the RAU process is performed on the WCDMA network after the call ends, and if so, the CSFB fallback fails, otherwise the CSFB fallback is successful.

Here, according to the preset CSFB optimization scheme, after the UE ends the normal call in the WCDMA network, the UE should quickly return to the LTE network.

In order to implement the method of the embodiment of the present invention, the embodiment of the present invention further provides a CSFB fallback result detecting device. As shown in FIG. 5, the device includes:
