detailed description

In order to understand the characteristics and technical contents of the embodiments of the present invention in more detail, the realization of the embodiments of the present invention is elaborated below in conjunction with the accompanying drawings, and the accompanying drawings are only for reference and description, and are not used to limit the present invention Example.

[0039] Under normal circumstances, a terminal with CSFB function can search for the LTE network when it is turned on, completes the joint registration of the LTE/2G network, and can perform voice calling and calling.

The CSFB process includes three stages: 1) UE initiates a call (corresponding to MO) in LTE network, or receives paging (corresponding to MT); 2) UE falls back and searches for suitable GSM cell/ Access to the WCDMA cell; 3) UE reads the system broadcast message of the GSM cell/WCDMA cell and establishes a voice call.

Along with LTE base station scale constantly expands, and part old GSM/TDSCDMA base station withdraws from the network and re-cultivates, the configuration of original network deployment on the base station signaling side is not updated in real time, and there is a network issue to The configuration information of the UE is inconsistent with the actual deployment situation, which leads to various abnormal situations in the inter-system (InterRAT) voice call of CSFB, such as failure to connect, repeated connection failures, and the like.

In order to solve the call problem caused by the incompatibility of network deployment, each terminal manufacturer has adopted various optimization means to improve the call experience, and for verifying the rationality of the CSFB optimization scheme, it is necessary to analyze the The CSFB process is detected in order to improve the CSFB optimization scheme in a targeted manner.

The CSFB fallback scheme adopts the 3GPP R8 redirection fallback scheme, and in the CSFB deployment process, the CSFB process will be abnormal due to the problem of parameter configuration probabilistically. For this reason, the embodiment of the present invention provides a method for detecting CSFB fallback results under the scenario of IDS RSCP uplink reporting due to the fallback target GSM cell designated by the network side being interfered by the adjacent TDSCDMA cell network.

In various embodiments of the present invention, in the CSFB process of carrying out the instruction information based on the instruction terminal adopting the preset CSFB optimization scheme to carry out voice service, detect the voice call of the terminal under the Global System for Mobile Communications GSM network State: The voice call of the terminal under the GSM network is triggered based on the specified GSM cell being interfered by the TDSCDMA cell adjacent to the cell, causing the terminal to initiate an RSCP uplink report on received signal code power; at least based on Detecting the voice call status, judging whether the CSFB falls back successfully; wherein, the indication information is carried in the attach accept message sent by the LTE base station to the terminal; the attach accept message is the attach request sent by the terminal to the LTE base station After the message is sent by the LTE base station; the CSFB process is triggered when the terminal receives the paging message sent by the LTE base station.

Adopt the scheme that the embodiment of the present invention provides, can under the scenario that causes TDS RSCP uplink to report because the fallback target GSM sub-district specified by the network side is interfered by the adjacent district TDSCDMA sub-district network, detects the voice under the GSM network in the CSFB process Call status, so as to finally determine the fallback result of CSFB. In this way, in the subsequent CSFB process, the optimization scheme can be further improved to improve the probability of CSFB process success, so as to improve the user's call experience.

Fig. 1 is the schematic flow sheet of the fallback result detection method of CSFB that the embodiment of the present invention provides, as shown in Figure 1, the fallback result detection method of described CSFB comprises the following steps:

Step 101: in the instruction information that adopts preset CSTO optimization scheme to carry out voice service based on instruction terminal to carry out CSFB process, detect the voice conversation state of described terminal under Global System for Mobile Communications GSM network;

Here, the voice call of the terminal under the GSM network is based on the specified GSM cell being interfered by the TDSCDMA cell of the adjacent cell and causing the terminal to initiate the received signal code power RSCP uplink report and triggered . For example, the voice conversation of the terminal under the GSM network is triggered after the terminal initiates an RSCP uplink report for the received signal code power of the TDSCDMA cell based on the specified GSM cell being interfered by the adjacent cell TDSCDMA cell.

[0049] Wherein, the indication information is carried in the attach accept message sent by the LTE base station to the terminal; the attach accept message is sent by the LTE base station after the terminal sends an attach request message to the LTE base station; the The CSFB process is triggered when the terminal receives the paging message sent by the LTE base station.

In actual application, a network environment applied to the embodiment of the present invention can be constructed by means of laboratory simulation, that is to say, the scene where the terminal described in the embodiment of the present invention is obtained by means of simulation, so that , on the one hand, the staff does not need to go to the site for testing, which can reduce the cost of personnel; The reappearance of the CSFB abnormal scene in the on-site network 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, detection is positioned at the voice call status of the described terminal under the simulated network environment under the GSM network.

Step 102: at least based on the detected voice call status, judge whether the CSFB falls back successfully.

In a specific embodiment, when it is detected that the voice call of the terminal in the GSM network is interrupted (i.e. not continued), it is determined that the CSFB fails to fall back.

In another specific embodiment, after the end of the voice call under the GSM network, detect whether the terminal returns to the LTE network within the preset duration; when the terminal does not return within the preset duration When using an LTE network, it is determined that the CSFB fallback fails. Here, in practical applications, the preset duration can be set as required.

In a specific scenario, when it is detected that the voice call of the terminal in the GSM network is not interrupted, that is, the terminal maintains a voice call after the voice call in the GSM network is established, the voice call in the GSM network After the end of the voice call, it is detected whether the terminal returns to the LTE network within the preset time length; when the terminal does not return to the LTE network within the preset time length, 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 falls back successfully. That is to say, when it is detected that the voice call of the terminal on the GSM network is not interrupted, that is, the terminal maintains the voice call after the voice call on the GSM network is established, and the voice call on the GSM network ends Afterwards, when the terminal returns to the LTE network within the preset time period, it is determined that the CSFB fallback is successful.

In another specific embodiment, the method further includes: when detecting that the measurement report reported by the terminal indicates that the terminal supports UMTS terrestrial wireless access UTRA, determining that the CSFB fallback fails. For example, the terminal capability (FGI) bit 22 in the measurement report MR reported by the UE is not equal to 0, and at this time, it is determined that the CSFB fallback fails.

Here, during actual application, it is possible to detect whether the voice call of the terminal in the GSM network is interrupted through relevant signaling, and in the same way, to detect whether the terminal returns to LTE within a preset duration through relevant signaling The network determines whether the FGI bit 22 is 0 through related signaling.

Like this, the method that the embodiment of the present invention provides, in the execution CSFB process based on the instruction information that instructs the terminal to adopt the preset CSTO optimization scheme to carry out the voice service, detects the voice call of the terminal under the Global System for Mobile Communications GSM network Status: The voice call of the terminal under the GSM network is triggered after the terminal initiates an RSCP uplink report on received signal code power due to the interference of the designated GSM cell by the adjacent cell TDSCDMA cell; at least based on Detected voice call status, judging whether the csro falls back successfully; wherein, the indication information is carried in the attach accept message sent by the LTE base station to the terminal; the attach accept message is an attach request sent by the terminal to the LTE base station After the message is sent by the LTE base station; the CSFB process is triggered when the terminal receives the paging message sent by the LTE base station. By adopting the solution provided by the embodiment of the present invention, it is possible to detect the voice call status under the GSM network during the CSTO process in the scenario where the TDS RSCP uplink report is caused because the fallback target GSM cell designated by the network side is interfered by the adjacent TDSCDMA cell network, In this way, the fallback result of CSFB is finally determined. In this way, in the subsequent CSFB process, the optimization scheme can be further improved to increase the success probability of the CSFB process, so as to improve the call experience of the user.

In addition, detection is positioned at the voice conversation state of the described terminal under the simulation network environment under the GSM network, adopts the mode of simulation and does not need staff to go to the scene, and can remove other factors that affect detection, so, can greatly reduce personnel At the same time, the influence of other factors on the detection results in the scenarios described in the embodiments of the present invention can be eliminated.

Embodiment Below in conjunction with an application embodiment, the present invention is described in further detail again.

In this application embodiment, construct a network environment by emulation platform, comprise frequency division duplex (FDD)-LTE sub-district, TDSCDMA sub-district, GSM sub-district; Wherein, dispose TDSCDMA in the LTE SIB and be neighbor cell information, configure The GSM cell is a neighboring cell, and the LTE neighboring cell information is configured in ^TDSCDMA SIB 18.

The abnormal scenario of this application embodiment is: the TDS RSCP uplink report is caused by the TDSCDMA cell network interference of the adjacent TDSCDMA cell network in the fallback target GSM cell designated by the network side, causing the UE to fail to fall back to the GSM call. For this abnormal scenario, the terminal The measurement report MR is reported for optimization, thereby verifying the effectiveness and rationality of the call optimization scheme on the terminal side.

The detection method of the fall-back result of this application embodiment CSFB, as shown in Figure 2, may further comprise the steps:

Step 201: UE registers on the LTE cell, and performs an attach process;

[0065] Specifically, the UE is an MT, and after the UE is powered on, it first executes an Evolved Packet System (EPS, Evolved Packet System)/International Mobile Subscriber Identity (IMSI, International Mobile Subscriber Identification Number) attach procedure.

[0066] Wherein, this process includes triggering the UE to send an attach request message (Attach Request) to the LTE base station, and receiving an attach accept message (Attach Accept) sent by the LTE base station, wherein the attach accept message carries an indication The terminal uses a preset CSFB optimization scheme to perform voice service indication information. Fig. 3 is a schematic diagram 1 of the emulation code of the embodiment of the present invention, wherein: IMS voice over PS (V)=Not supported (0), represents the instruction {item information.

Step 202: the network side configures RRC Reconfiguration, impels UE to perform measurement report MR, and measures adjacent TDSCDMA cells.

Step 203: the network side triggers the MT CSFB process, and the network side sends a paging message (Paging) to the UE to start the CSFB process;

[0069] Here, during actual application, the MO first needs to initiate a call to the MT, and then the MT receives the paging message sent by the network side.

Specifically, after the Mobile Service Switching Center (MSC) in the network receives the initial address request (IAM) incoming message, according to existing SGs association and mobile management entity (Mffi, Mobility Management Entity) information, send SGsAP-PAGING The -REQUEST message is sent to the MME. Here, the SGsAP-PAGING-REQUEST message carries the following information: IMSI, Temporary Mobile Subscriber Identity (TMSI, Temporary Mobile Subscriber Identity), service identifier (Service indicator), calling number, and location area information.

[0071] After receiving the message, the MME sends a paging (Paging) message to the base station, and the base station initiates the Paging process of the air interface. UE establishes connection and sends Extended Service Request message to MME, MME sends SGsAP-SERVICE-REQUEST message to MSC, MSC receives this message, and does not resend paging request message to MME. In order to avoid the call connection process, the caller's waiting time is too long, the MSC receives the SGs Service Request message that includes an idle state indication, and first notifies the caller that the call is in the connection process. 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. The CS Fallback Indicator is used to indicate that the base station UE needs to fall back to the UMTS Terrestrial Radio Access Network (UTRAN, UMTS Terrestrial Radio Access Network) due to the CSFB service. Network) /GSM/EDGE Radio Access Network (GERAN, GSM EDGE Radio Access Network).

In the attachment process, the UE receives the LTE_RRCConnectionRelease signaling sent by the LTE base station, that is, the redirection command. The redirection command carries the frequency point information of the specified GSM cell, that is, the frequency point information of the target GSM cell.

As shown in Figure 4, the base station issues an R8 redirection command (rrcConnectionRelease_R8 (0)) to the UE. point information to access the target GSM cell.

Step 204: UE accesses the GSM sub-district according to the specified frequency point information (that is, the frequency point information of the target GSM sub-district), at this time, simulated by the emulation platform: the UE according to the specified frequency point information (that is, the frequency point information of the target GSM sub-district) During the process of accessing the GSM cell for voice calls, the ms RSCP uplink report is caused by the network interference of the neighboring TDSCDMA cell;

At this moment, detect the UE in this case, the voice call status in the target GSM cell; that is, check whether the UE can set up a call in the target GSM cell and keep the call in the CS domain unaffected in this case, After the CS call is over, it can quickly FastReturn and successfully return to the LTE network; that is, whether it can return to the LTE network within the preset time.

Step 205: check UE in this case, whether the voice call state of CS domain is not affected, promptly detect UE in this case, whether can keep voice call, if so, then execute step 206; Otherwise, explain CSFB fallback failed, that is to say, the preset CSFB optimization scheme failed;

[0077] Step 206: After detecting the end of the call, whether the UE returns to the LTE network within a preset period of time, if so, it indicates that the CSFB falls back successfully, otherwise, it indicates that the CSFB fails to fall back.

Step 207: when detecting that the FGI bit 22 indicated by the measurement report MR reported by the UE is not equal to 0, it is determined that CSFB falls back and fails.

[0079] In practical applications, the execution order of step 207 and step 205 can be exchanged, which is not limited in this embodiment.

[0080] Here, according to the preset CSFB optimization scheme, after the normal call of the UE in the TDSCDMA network ends, the UE should quickly return to the LTE network.
