Detailed Description
The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. The components of embodiments of the present invention generally described and illustrated in the figures herein may be arranged and designed in a wide variety of different configurations. Thus, the following detailed description of the embodiments of the present invention, presented in the figures, is not intended to limit the scope of the invention, as claimed, but is merely representative of selected embodiments of the invention. All other embodiments, which can be derived by a person skilled in the art from the embodiments of the present invention without making any creative effort, shall fall within the protection scope of the present invention.
The mobile terminal is compatible with various network systems, is connected to a 4G or 5G high-system network through a joint attachment process and is used for completing data services; then, the high-system network is associated with the low-system network such as 2G or 3G, so as to ensure that the mobile terminal can smoothly complete the voice service; when the mobile terminal initiates a calling party or receives a called request, the mobile terminal needs to drop the connected network from the low-standard network.
However, the mobile terminal often fails to fall back, resulting in call failure or abnormal call; in the research on the reason of the fallback failure, the inventor finds that when the fallback of the mobile terminal is rejected, the network side returns a message of 'protocol state mismatch'; generally, the protocol states are not matched, which is mostly caused by the reason that a call hold or a multi-party call occurs in the mobile terminal, or the location update of the mobile terminal is not synchronized with other service states.
By checking the log record of the mobile terminal, the situation that the position update of the mobile terminal is asynchronous with other service states and the next voice call service is not influenced is found, and the reason is explained that the mobile terminal cannot fail to fall back; repeated tests of the inventor show that after the call is finished, the mobile terminal immediately initiates a CM service request signaling before returning to the high-standard network, and at the moment, if the mobile terminal requests the call again, the mobile terminal is rejected by the network side.
Analyzing the reason, after the call is finished, the mobile terminal does not return to the high-standard network immediately due to some reasons, and still stays on the 2G or 3G network within a period of time; at this time, if the mobile terminal triggers a non-voice service request, the request will be sent to the 2G or 3G network side, and the network side will allocate a 2G or 3G service channel for the request; even if the mobile terminal subsequently returns to the high-standard network, the service channel still stays on the 2G or 3G network. Because a mobile terminal can only distribute a service signal at the 2G or 3G network side, if the mobile terminal initiates a call service request again in the scene, the mobile terminal can cause the network side to mistakenly assume that the mobile terminal is in a call state due to a service channel occupied by the non-voice service request, and then reject the call service request, so that the mobile terminal often has the situations of call failure or abnormal call, and the reliability of the voice call of the mobile terminal is poor.
Based on the above problems, embodiments of the present invention provide a method, an apparatus, and a mobile terminal for recovering a network resource abnormality; the technology can be applied to mobile terminals such as mobile phones, tablet computers, Personal Digital Assistants (PDAs), vehicle-mounted computers and the like; the techniques may be implemented in associated software or hardware, as described by way of example below.
Referring to fig. 1, a flow chart of a method for recovering from a network resource abnormality is shown; the method is applied to the mobile terminal and comprises the following steps:
step S102, if the mobile terminal is quickly redirected to a high-standard network, checking whether the mobile terminal currently has a non-voice service of the low-standard network;
when the mobile terminal performs a voice call service, the mobile terminal needs to fall back from a high-standard network to a low-standard network, and occupies a service channel of the low-standard network to perform a call; after the call is finished, the network side sends out a channel release signaling (also called a channel release notification) to notify the mobile terminal to release the service channel, and in the release process, the mobile terminal is quickly redirected to a high-system network. However, a communication failure may occur on the network side, which may cause the channel release signaling to be missed, and may cause the mobile terminal not to immediately return to the high-standard network; when the mobile terminal finds the situation, the corresponding timer is started, and after the timer reaches the set time, the mobile terminal automatically returns to the high-standard network.
As can be seen from the above analysis, in the period of time after the voice call is finished and before the mobile terminal returns to the high-standard network, if the mobile terminal triggers the non-voice service, a service channel connected to the low-standard network will exist in the mobile terminal, and the mobile terminal is always in the voice call state when viewed from the network side; in order to avoid failure of the secondary voice call due to existence of a non-voice service when the mobile terminal is redirected to the high-standard network, it is necessary to check whether the mobile terminal currently has the non-voice service of the low-standard network.
Generally, by inquiring log records of a mobile terminal, whether the mobile terminal triggers a non-voice service or not in the period after a voice call is finished and before the mobile terminal returns to a high-standard network can be known, and if the non-voice service is triggered by the log records, the mobile terminal is determined to have the non-voice service of a low-standard network at present.
And step S104, if the non-voice service of the low-standard network exists in the mobile terminal at present, sending a re-registration flow to the high-standard network.
In order to interrupt the non-voice service, a service channel connecting the mobile terminal and the low-standard network is released, and the mobile terminal sends a re-registration flow to the high-standard network; after the re-registration process is initiated, the previous service channel of the mobile terminal is released, the mobile terminal is reconnected to a 4G or 5G high-standard network through the combined attachment process, and then the mobile terminal is associated with a 2G or 3G low-standard network through the high-standard network so as to complete the re-layout of the network connected with the mobile terminal.
In the method for recovering network resource abnormality provided by the embodiment of the invention, if the mobile terminal is quickly redirected to a high-standard network, whether the mobile terminal currently has a non-voice service of the low-standard network is checked; if yes, initiating a re-registration process to the high-standard network; the method can ensure that when the mobile terminal is quickly redirected to the high-standard network, no service channel exists between the mobile terminal and the low-standard network, so that the subsequent voice call is smoothly connected, and the reliability of the voice call of the mobile terminal is improved.
Referring to fig. 2, a flow chart of another method for recovering from a network resource abnormality is shown; the method is implemented on the basis of the method shown in fig. 1; the method is applied to the mobile terminal and comprises the following steps:
step S202, detecting whether the mobile terminal initiates quick redirection to a high-standard network; if yes, go to step S204; if not, executing step S202;
generally, after a voice call of a mobile terminal is finished, a network side issues a channel release signaling to the mobile terminal, and the mobile terminal quickly redirects to a high-standard network after receiving the signaling; if the network side does not send the signaling, the mobile terminal can be quickly redirected to the high-standard network after the timer reaches the set time. Therefore, when receiving the channel release signaling sent by the low-system network, the mobile terminal starts to quickly redirect to the high-system network; or, when the timer reaches the set time, the mobile terminal starts to redirect to the high-standard network quickly.
Step S204, checking the log record of the mobile terminal;
step S206, judging whether a log record of the last call completion receives a channel release notice of the low-standard network; if not, executing step S208; if yes, ending;
step S208, judging whether the mobile terminal initiates a non-voice service after the last call is finished; if yes, go to step S210; if not, ending;
the log records usually store call records in a set time period from the current time, and record the occurrence time of each call record; due to the limitation of the storage space of the mobile terminal, the call records exceeding the set time period may be deleted; the log record of the last call ending can be understood as a call record closest to the current time.
Step S210, determining that the mobile terminal currently has a non-voice service of a low-standard network;
the channel release notification may be a channel release signaling; if the mobile terminal does not receive the channel release notification, it is likely that the mobile terminal cannot be immediately redirected to the high-standard network, and a user may trigger a non-voice service within a period of time before the mobile terminal returns to the high-standard network after the voice call is finished; if the log records that the mobile terminal initiates the non-voice service after the last call is ended, the fact that a service channel exists between the mobile terminal and the low-standard network can be determined.
Step S212, a re-registration process is sent to the high-standard network.
In the above manner, whether the mobile terminal currently has the non-voice service of the low-standard network can be determined by detecting the log record, and if so, a re-registration process is sent to the high-standard network to release the service channel occupied by the non-voice service; the method can ensure that when the mobile terminal is quickly redirected to the high-standard network, no service channel exists between the mobile terminal and the low-standard network, so that the subsequent voice call is smoothly connected, and the reliability of the voice call of the mobile terminal is improved.
Referring to fig. 3, a flow chart of another method for recovering from a network resource abnormality is shown; the method is implemented on the basis of the method shown in fig. 2; the method is applied to the mobile terminal, wherein the high-standard network comprises 5G, 4G or 4G +, and the low-standard network comprises 2G or 3G.
The method comprises the following steps:
step S302, detecting whether the mobile terminal initiates quick redirection to a high-standard network; if yes, go to step S304; if not, executing step S302;
step S304, checking the log record of the mobile terminal;
step S306, judging whether a log record of the last call completion receives a channel release notice of the low-standard network; if not, go to step S308; if yes, go to step S316;
step S308, judging whether the mobile terminal initiates a non-voice service after the last call is finished; if yes, go to step S310; if not, go to step S316;
step S310, determining that the mobile terminal currently has a non-voice service of a low-standard network;
step S312, performing the detachment operation of the high-standard network;
in the detachment process, the mobile terminal releases the attachment relation with the high-standard network, including the association relation between the high-standard network and the low-standard network, and also releases the service channel of the non-voice service with the low-standard network.
Step S314, re-initiate the joint attach operation of the high-system network, so as to associate the high-system network with the low-system network.
In the above joint attachment operation process, after the high-standard network receives the joint attachment request sent by the mobile terminal, the high-standard network may derive VLR (Visitor Location Register) information of the CS (Circuit Switched Domain) Domain while performing the attachment operation; the high-level network initiates a location updating request to the VLR, and the VLR marks the mobile terminal as attached and stores the address of the mobile terminal after receiving the location updating request; in the mode, the high-standard network establishes the associated information of the low-standard network for the mobile terminal through the GCs interface, and the association between the high-standard network and the low-standard network is realized.
Step S316, if the mobile terminal initiates a call, a CSFB (Circuit Switched Fallback) procedure is started to fall back to the low-standard network, and a voice service request is sent to the low-standard network, so as to implement a call.
When the mobile terminal is called, if receiving a call notification sent by a high-standard network, sending an extended service request to a related low-standard network; and when receiving the request response information sent by the low-standard network, starting the CSFB process to fall back to the low-standard network, and sending a voice service request to the low-standard network so as to realize the conversation.
Specifically, if the high standard network receives the information that other mobile terminals call the mobile terminal through the CS domain, the high standard network sends a CS domain call notification to the mobile terminal; after receiving the notification, the mobile terminal sends an extended service request to the associated low-standard network (or GSM network); after the request is passed, the mobile terminal can fall back to the low-standard network. After the call is completed, the low-standard network informs the mobile terminal to release the traffic channel (also called a call link) of the CS domain.
The method can ensure that no service channel exists between the mobile terminal and the low-standard network when the mobile terminal is quickly redirected to the high-standard network, so that the subsequent voice call is smoothly connected, and the reliability of the voice call of the mobile terminal is improved.
Referring to fig. 4, a flow chart of another method for recovering from a network resource abnormality is shown; the method is realized by the interaction of a mobile terminal, a high-standard network (taking an LTE network as an example) and a low-standard network (taking a GSM network as an example); the method comprises the following steps:
step S402, the Mobile terminal triggers registration, and initiates a joint attachment process of LTE (Long Term Evolution, Long Term Evolution technology) and IMSI (International Mobile Subscriber identity Number);
step S404, the LTE network uses the GCs port as the associated information of the registered GSM network in the movement;
step S406, when the LTE network receives that other mobile terminals call the mobile terminal information through the CS domain, the LTE network sends a CS domain call notification to the mobile terminal;
step S408, the mobile terminal sends an extended service request to the associated GSM network;
step S410, the GSM network sends request response information to the mobile terminal;
step S412, the mobile terminal falls back to the GSM network from the LTE network to complete the voice call service;
step S414, after the conversation is finished, the mobile terminal initiates quick redirection to a high-standard network;
step S416, checking whether the mobile terminal has the non-voice service of the low-standard network currently;
step S418, if yes, determining that the mobile terminal currently has the non-voice service of the low-standard network;
step S420, performing the detachment operation of the high-standard network;
step S422, the joint attach operation of the high-standard network is re-initiated, so that the high-standard network is associated with the low-standard network.
Step S424, if the mobile terminal initiates a call, the CSFB procedure is started to fall back to the low-standard network, and a voice service request is sent to the low-standard network, so as to implement a call.
The method can ensure that no service channel exists between the mobile terminal and the low-standard network when the mobile terminal is quickly redirected to the high-standard network, so that the subsequent voice call is smoothly connected, and the reliability of the voice call of the mobile terminal is improved.
