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 will be described in detail below in conjunction with the accompanying drawings, and the attached drawings are only for reference and description, and are not intended to limit the present invention Example. [0044] Under normal circumstances, the terminal with CSFB function can search for LTE network when it is turned on, completes joint registration of LTE/2G network, and can perform voice calling and calling.

[0045] The CSTO process includes three stages: 1) UE initiates a call (corresponding to MO) in the LTE network, or receives paging (corresponding to MT); 2) UE falls back under the guidance of the LTE network and searches for a suitable GSM cell to perform Access; 3) UE reads the GSM cell system broadcast message and establishes a voice call.

In addition, a more important process in the CSFB process is the channel acquisition process, and the channel acquisition process is set forth below.

Fig. 1 is the channel acquisition flowchart of the embodiment of the present invention, as shown in Fig. 1, described channel acquisition flow process comprises the following steps:

Step 101: UE boots up, and executes joint evolved packet system (EPS, Evolved Packet System)/International Mobile Subscriber Identity code (IMSI, International Mobile Subscriber Identification Number) to attach.

[0049] Step 102: UE receives the CS paging message, and starts to execute the CSFB process.

Step 103: UE receives the redirection order issued by network side, carries the frequency point information of GSM sub-district in redirection order.

[0051] Here, the redirection command is implemented through the LTE_RRCConneCtionReleaSe signaling.

[0052] Step 104: The UE scans the frequency points of the GSM cell based on the frequency point information of the GSM cell carried in the redirection command, and selects a frequency point of the GSM cell for communication.

[0053] Here, the frequency point of the selected GSM cell is called the target frequency point.

Step 105: UE sends a channel request message (CHANNEL_REQUEST) to the network based on the target frequency point, i.e. an access request message.

[0055] Here, after the terminal sends the CHANNEL_REQUEST for the first time, it starts the T3120 timer to count the number of retransmissions of the CHANNEL_REQUEST through the random access process, and presets the maximum number of retransmissions. When the timer T3120 expires and reaches the "maximum number of retransmissions", the terminal will start the T3126 timer to count the time during which the terminal does not send CHANNEL_REQUEST in silence; If there is a response to the channel request of the terminal, the terminal gives up the request attempt.

[0056] Step 106: The UE receives the IM message replied by the network, and obtains the channel allocated by the network through the IM message.

[0057] Along with the continuous expansion of the scale of LTE base stations, and the withdrawal and re-cultivation of some old GSM/TDS-CDMA 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 network issues 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.

[0058] In order to solve such call problems caused by network deployment incompatibility, each terminal manufacturer has adopted various optimization means to improve the call experience. In order to verify 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. To this end, the embodiment of the present invention provides a method for detecting a CSFB fallback result in a scenario where a plurality of wrong GSM cell information is delivered by the network side.

[0060] In various embodiments of the present invention, during the execution of CSFB based on the instruction information indicating that the terminal adopts a preset CSFB optimization scheme to perform voice services, the voice call status of the terminal in the neighboring cell of the specified cell is detected; The voice call of the terminal in the neighboring cell of the designated GSM cell is triggered when the frequency scanning of the designated GSM cell is successful based on the designated GSM cell frequency point information and the identification of the designated cell is invalid; the designated GSM cell frequency point The information is carried in the redirection command sent by the LTE base station; using the detected voice call status, it is judged whether the CSFB falls back successfully; wherein, the indication information is carried in the attach acceptance 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 CSFB process is triggered when the terminal receives a paging message sent by the LTE base station.

Adopt the scheme that the embodiment of the present invention provides, the frequency point information of wrong GSM sub-district can be configured on the network side so that the terminal recognizes that the designated GSM sub-district is invalid and detects the voice call status of the adjacent sub-district of the designated GSM sub-district in the CSFB process, In this way, the fallback result of CSFB is finally determined. In this way, in the subsequent CSTO process, the optimization scheme can be further improved to increase the success probability of the CSFB process, so as to improve the user's call experience. _

Fig. 2 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 2, the fallback result detection method of described CSFB comprises the following steps:

Step 201: in the CSFB process of carrying out the instruction information based on the instruction terminal adopting the preset CSIB optimization scheme to carry out the voice service, detect the voice call state of the adjacent cell of the terminal in the designated cell;

Here, the voice call of the adjacent cell of the specified GSM cell by the terminal is triggered when the frequency sweep of the specified GSM cell is successful and the identification of the specified GSM cell is invalid based on the frequency information of the specified GSM cell; The specified GSM cell frequency point information is carried in the redirection command sent by the LTE base station.

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 CSFB procedure is triggered to be executed 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 through laboratory simulation, that is to say, the scene where the terminal described in the embodiment of the present invention is obtained through 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, the voice conversation state of the terminal located in the simulated network environment in the adjacent cell is detected.

Step 202: Utilize the voice call state of detection, judge whether described CSFB falls back successfully.

[0069] Specifically, when it is detected that the terminal does not initiate an access request to the adjacent cell, it is determined that the CSFB fallback fails.

[0070] Wherein, when the terminal initiates an access request to the adjacent cell, and when it is detected that the access request cause value carried in the access request sent by the terminal to the adjacent cell is not a preset value, it is determined that the CSFB fallback failed.

[0071] Here, when the access request cause value carried in the access request sent by the terminal to the neighboring cell is a preset value, and after the terminal accesses the neighboring cell, when it is detected that the voice call has not been successfully established , it is determined that the CSFB fallback fails. [0072] Of course, when it is detected that the terminal successfully establishes a voice call with the adjacent cell, it is determined that the CSTO falls back successfully.

Wherein, during actual application, in order to prevent the detection time process, when it is detected that the terminal does not send an access request to the adjacent cell within the preset duration, it is determined that the CSFB falls back to failure.

[0074] Here, the preset duration can be set as required. In addition, it can be detected by setting a timer, specifically, setting a timer, and when it is detected that the terminal does not send an access request to the neighboring cell before the timer expires, it is determined that the CSFB fallback fails.

[0075] The method provided by the embodiment of the present invention detects the voice call status of the terminal in the neighboring cell of the specified cell during the execution of CSFB based on the instruction information indicating that the terminal uses a preset CSFB optimization scheme to perform voice services; the The voice call of the terminal in the neighboring cell of the designated GSM cell is triggered when the frequency scanning of the designated GSJ1 cell is successful based on the designated GSM cell frequency point information and the identification of the designated cell is invalid; the designated GSM cell frequency point information carries In the redirection command sent by the LTE base station; use the detected voice call status to determine whether the CSFB fallback is successful; wherein the indication information is carried in the attach accept message sent by the LTE base station to the terminal; the 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 CSFB process is triggered when the terminal receives the paging message sent by the LTE base station, and is implemented by the present invention The solution provided by the example can detect the voice call status of the adjacent cell of the designated GSM cell during the CSFB process in the scenario where the frequency information of the wrong GSM cell is configured on the network side, making the terminal identification of the designated GSM cell invalid, so as to finally determine the fallback of CSFB As a result, in this way, in the subsequent CSFB process, the optimization scheme can be further improved to increase the probability of the success of the CSFB process, so as to improve the user's call experience.

In addition, to detect the voice conversation status of the terminal located in the simulated network environment in the adjacent cell, the simulated mode does not require staff to go to the scene, and other factors affecting the detection can be removed, so that it can be greatly reduced. At the same time, it can eliminate the influence of other factors on the detection results in the scenarios described in the embodiments of the present invention.

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

In this application embodiment, construct a network environment by emulation platform, comprise time division duplex (TDD)-LTE sub-district, TDSCDMA sub-district, GSM sub-district; Wherein, dispose GSM neighboring sub-district information in LTE SIB, in GSM SI Configure LTE neighbor cell information.

The abnormal scenario of this application embodiment is: the network side misconfigures the frequency point information of multiple GSM cells, and the UE can access the correct cell according to the previous neighbor cell information after the access attempt fails, thereby verifying the call optimization scheme on the UE side effectiveness and rationality.

The detection method of the fall-back result of this application embodiment CSFB, as shown in Figure 3, may further comprise the steps:

[0081] Step 300: UE registers on the LTE cell, and performs an attach procedure;

[0082] Specifically, the UE is an MT, and after the UE is powered on, it first executes a joint EPS/IMSI attach procedure.

[0083] 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. 4 is a schematic diagram 1 of the simulation code of the embodiment of the present invention, wherein: IMS voice over PS (V) and Not supported (O) represent the indication information.

Step 301: 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;

[0085] Here, during actual application, it is necessary for the MO to first initiate a call to the MT, and then the MT receives the paging message issued by the network side.

Specifically, after the Mobile Services Switching Center (MSC) in the network receives the initial address request (IAM) incoming message, it sends the SGsAP-PAGING according to the existing SGs association and mobility management entity (MME, Mobility Management Entity) information The -REQUEST message is sent to the MNE. 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.

[0087] 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. The UE establishes a connection and sends an Extended Service Request message to the MME, and the MME sends a SGsAP-SERVICE-REQUEST message to the MSC. After receiving this message, the MSC does not resend the paging request message to the JE. 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. )/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 frequency point information of multiple wrong GSM cells. As shown in Figure 5, the base station sends an R8 redirection command (rrcConnectionRelease_R8 (0)) to the UE, but the command carries multiple wrong GSM cell frequency information, which does not match the GSM cell of the neighboring cell. This abnormal scenario cannot Guide the terminal to fall back to the target GSM cell.

Step 302: The UE recognizes that the target GSM cell is an invalid cell;

[0090] Here, the UE may recognize that the target GSM cell is an invalid cell through multiple failed access attempts. Specifically, a timer can be set. Before the timer expires, multiple attempts to access the target GSM cell are attempted. When the timer expires and the target GSM cell is still not accessed, the UE recognizes that the target GSM cell is an invalid cell.

Step 303: detect whether UE initiates an access request message (that is, the channel request message in step 105) to the neighboring GSM cell within the specified timer duration, if yes, then perform step 304, otherwise, illustrate that CSFB falls back Failed, that is to say, the preset CSFB optimization scheme failed;

[0092] Here, after the UE recognizes that the target GSM cell is an invalid cell, it first initiates a power scanning process to find a neighboring GSM cell, and then sends an access request message to the neighboring GSM cell.

Step 304: check whether the access request cause value carried in the access request is a preset value (i.e. the correct access request cause value), if yes, then perform step 305, otherwise, it indicates that CSFB fails to fall back, and also That is to say, the preset CSFB optimization scheme failed;

[0094] Here, during head-on applications, it is necessary to parse out the access request cause value (cause) from the access request, and then detect whether the carried access request cause value is a preset value.

Step 305: continue the CSFB follow-up process, in the follow-up process, detect whether the UE has successfully set up a CS voice call with the neighboring GSM sub-district, if yes, explain that CSFB falls back successfully, explain that the preset CSFB optimization scheme is successful, otherwise, explain 03 ^Fallback failed, that is to say, the preset CSFB optimization scheme failed.
