detailed description

The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only some, not all, embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without creative efforts fall within the protection scope of the present invention.

Referring to FIG. 1 , it is a schematic flowchart of a method for processing abnormal network communication functions provided by an embodiment of the present invention. In the embodiment of the present invention, the method includes steps:

S101. Detect the network communication function of the modem.

In some feasible implementation manners, the execution subject of the method for handling abnormal network communication functions provided by the embodiments of the present invention may be an application processor (English: Application Processor, AP for short) and a modem, that is, the application processor and the modem cooperate to complete. Among them, the above-mentioned AP is used to expand audio and video functions and special interface VLSI on the basis of low-power CPU, and is an important component in smart phones. The AP and the baseband processor (or baseband chip) may be two independent chips, and the baseband chip includes multiple modules such as a modem. The AP and the baseband processor may also be integrated into one chip, which may be determined according to actual application scenarios, and is not limited here. The modem is used to convert baseband signals to radio frequency signals, convert radio frequency signals to baseband signals, handle access stratum (AS) and non-access stratum (NAS) signaling, and interface with APs, etc.

In some possible implementations, the modem supports multiple protocol stacks. When the modem is abnormal, it can register with the network through various protocol stacks it supports to restore the communication function. When the modem detects that the network communication function is abnormal; such as crash/assert, the modem will crash/dump; and the demodulation CRC of the up/down channel has a high probability of failure, etc.; data processing cannot be performed normally, resulting in users being unable to access the Internet and make calls Wait. In order to restore the normal network, the modem needs to judge the cause of the abnormal network communication function, and then avoid/automatically recover according to the specific cause. Further, after the modem has an abnormal network communication function, it may also send an indication message indicating the abnormal network communication function to the AP, and the AP executes a processing procedure for the abnormal network communication function.

In some feasible implementation manners, the reason why the modem handles the abnormality of the network function may include failure of the called terminal (Mobile Terminating, MT for short) call failure or mobile original calling (Mobile Original, MO) call failure, channel decoding failure, dedicated bearer activation Failure or dedicated bearer modification failure, public data network (Public DataNetwork, PDN) connection establishment failure, data transmission failure, location update failure, network registration failure, etc., are not limited here.

In some feasible implementation manners, the reasons for establishing a radio resource control (Radio Resource Control, RRC for short) connection are divided into RRC establishment initiated by the MT and RRC establishment initiated by the MO. The reasons for MT/MO call failure are: call blocking (user equipment (User Equipment, UE) initiates MO or before the RRC connection establishment of MT, according to the call blocking parameter of system information block (SystemInformation Block, referred to as SIB), the access blocking detection is performed, If it is detected that the access is blocked, the RRC connection establishment request message is not sent), and the RRC connection rejection message is received before the timer T300 times out (the base station performs access control or load control after receiving the RRC connection establishment request. If the connection is established, the base station sends an RRC connection rejection message to the UE), the RRC connection establishment or RRC connection rejection message sent by the base station is not received before the T300 timer expires, and the UE fails to send the RRC connection establishment request message (including the failure of the random access process ), any signaling process in the call establishment process fails (such as the network does not respond to the paging response message, authentication fails, etc.). When the UE fails to initiate an MT/MO call, it will cause abnormal network communication of the modem, and the modem can detect that the cause of the abnormal network communication is the failure of the MT/MO call.

In some feasible implementation manners, due to some network reasons, the legitimate UE registration network may sometimes be rejected by the network, resulting in no service, and the user must manually restart and retry the registration. Among them, the reasons for the failure of the UE to register with the network include the failure of the network authentication process, the signing problem between operators during international roaming, and the like. For example: after the UE sends an Attach Request (AttachRequest or LAU) message, it receives an Attach Reject (AttachReject) message from the network before the timer T3410 expires. ME), EPS services not allowed, PLMN not allowed (PLMN not allowed), tracking area not allowed (Tracking area not allowed), etc. When the UE enters an Out of Service (OOS) state after receiving the attach rejection, the modem may detect that the reason for the abnormality of the network communication function is the network registration failure and the like.

In some feasible implementation manners, the modem generally needs to perform dedicated bearer processing, including dedicated bearer activation or dedicated bearer modification, during network registration or network use of the UE. Dedicated bearer activation or dedicated bearer modification can be initiated by the UE or the network side. Specifically, the network side may initiate dedicated bearer activation or dedicated bearer modification by sending a dedicated bearer activation request (ACTIVATE DEDICATED EPS BEARER CONTEXT REQUEST) or a dedicated bearer modification request (MODIFY EPSBEARER CONTEXT REQUEST) to the mobile terminal. Specifically, the modem of the UE initiates dedicated bearer activation or dedicated bearer modification by sending a bearer resource allocation request message (BEARER RESOURCE ALLOCATION REQUEST) or a bearer resource modification request message (BEARER RESOURCE MODIFICATION REQUEST). However, during the process of activating or modifying the dedicated bearer, if the following situations occur on the UE side, the processing of the dedicated bearer will generate an exception, for example: the activation of the dedicated bearer fails or the modification of the dedicated bearer fails. These situations include: the dedicated bearer identifier to be activated conflicts with the existing default bearer identifier, the dedicated bearer identifier to be activated conflicts with the existing dedicated bearer identifier, the default bearer associated with the dedicated bearer to be activated has not been established, and the dedicated bearer When sending an activation completion message (ACTIVATEDEDICATED EPS BEARER CONTEXT ACCEPT) or sending a dedicated bearer modification completion message (MODIFY EPSBEARER CONTEXT ACCEPT), the RRC layer indicates that the sending of the message failed. The modem can determine whether the activation of the dedicated bearer or the modification of the dedicated bearer fails by detecting whether the above situation exists during the process of activating the dedicated bearer or modifying the dedicated bearer, so as to determine whether the processing of the dedicated bearer of the modem is abnormal. If it is detected that the activation of the dedicated bearer fails or the modification of the dedicated bearer fails, it can be determined that the network communication function of the modem is abnormal.

In some feasible implementation manners, a public data network (Public Data Network, PDN) is a wide area network established by a telecom operator, which provides services and technologies for accessing the wide area network, and provides users with high-quality data transmission services. PDN is a packet switching or circuit switching service provided by a local or long-distance telecommunications bureau. The packet switching services provided usually include X.25, frame relay, switched multi-megabit data service or asynchronous transfer mode, circuit switching service Including dial-up lines, switching 56 lines and ISDN. The mobile terminal accesses the PDN through an access point name (Access Point Name, APN), and different APNs correspond to different PDN networks, which are defined by operators. APN refers to a network access technology, which is a parameter that must be configured when the UE accesses the Internet, and it determines which access method the UE uses to access the network. For UE users, there are many types of external networks that can be accessed, such as: Internet, WAP website, group enterprise internal network, and industry internal private network. However, different access points have different access ranges and access methods. The PDN interconnects the network control center and the user's network access equipment through a modem for data communication, so as to achieve the purpose of surfing the Internet. When the connection between the UE and the PDN is successfully established, the user can normally access the Internet through the mobile phone. Once the PDN connection fails to be established, the mobile phone will not be able to access the Internet normally.

During operation, the modem detects in real time whether the PDN connection is successfully established, and when it detects that the PDN connection fails, it can be determined that the connection between the modem and the PDN fails to be established at this time. The UE initiates establishing a new PDN connection by sending a PDN connection request message, and the network side establishes a new default bearer for the new PDN connection. The reasons causing the PDN connection establishment failure include that the network side rejects the PDN connection establishment, the PDN connection establishment request message sent by the UE times out, or the RRC layer of the radio resource control protocol indicates that the PDN connection establishment request fails to be sent. The reasons why the network side rejects the PDN connection establishment request include: operator blocking, unknown APN, unknown PDN type, authentication failure, PDN type IPv4 is not allowed, PDN type IPv6 is not allowed, multiple PDNs are not allowed for the specified APN, or resources are limited, etc. . If the modem detects that the PDN connection fails, it can be determined that the network communication function of the modem is abnormal.

In some feasible implementations, the UE initiates the location registration process by sending a location update request message (such as LOCATION UPDATEREQUEST, TRACKING AREA UPDATE REQUEST, etc.). Before the UE completes the location update, the protocol stack exception or the network side rejects the location update. UE location update failed. The abnormal causes of location update failure also include: poor signal coverage or strong signal interference leading to RRC wireless link establishment failure, NAS layer receiving an error indication from RRC layer or receiving NAS signaling connection release indication from RRC layer, UE entering A new tracking area (TA), the RRC layer indicates that the location update request message fails to be sent, the UE sends the location update completion message (TRACKING AREA UPDATECOMPLETE) when the RRC layer indicates that the message fails to be sent, and the timer T3430 expires before it does not receive the message sent by the network side Location update permission message (TRACKING AREA UPDATE ACCEPT) location update rejection (TRACKING AREA UPDATE REJECT) message, location update rejection (TRACKING AREA UPDATE REJECT) message reason field detection failure, location update process conflicts with other processes, UE authentication failure or Security activation failed, etc. If it is detected that the location registration of the UE fails, it can be determined that the network communication function of the modem is abnormal.

In some feasible implementation manners, when the modem detects the abnormality of the network communication function, it can determine whether the cause of the abnormality of the network communication function is channel decoding failure, and if so, it can perform network repair. The foregoing channel decoding failure may include: a common channel decoding failure such as a paging paging channel, or a Broadcast channel decoding failure, etc., which are not limited here.

S102. When the network communication function of the modem is abnormal, disconnect the network connection between the modem and the current cell, and set the current cell as a forbidden cell.

In some feasible implementation manners, after the modem (or application processor, the embodiment of the present invention will use the modem as an example) detects that the network communication function of the modem is abnormal, it can disconnect the network connection between the modem and the current cell, and Set the current cell as a forbidden cell. In the specific implementation, the modem disconnects the network connection with the current cell and sets the current cell as a forbidden cell, which can prevent the modem from repeatedly trying to establish a network connection with the current cell when it searches the network again, thereby avoiding repeated network communication function abnormalities, which can Save power consumption.

S103. Search for a cell corresponding to the radio access technology RAT supported by the modem.

In some feasible implementation manners, after the modem is disconnected from the network connection of the current cell, it can re-search for an accessible network. In a specific implementation, the modem may search for a cell service corresponding to a radio access technology (Radio Access Technology, RAT) that it supports. At this time, since the network accessed by the modem when the network communication is abnormal has been set as a forbidden cell, when re-searching the network, the search objects not included in the forbidden cell can avoid re-accessing the forbidden cell, thereby avoiding the same network from appearing repeatedly The communication function is abnormal.

S104. If searching for a target cell corresponding to the RAT supported by the modem, establish a network connection between the modem and the target cell.

In some feasible implementation manners, if the cell corresponding to the RAT supported by the modem (that is, the target cell) is searched, a network connection between the modem and the target cell may be established, and network communication of the modem may be performed through the target cell. The modem establishes a communication connection with the target cell, and the network communication function of the modem can be quickly restored.

Further, in some feasible implementation manners, if the target cell corresponding to the RAT supported by the modem cannot be searched, the modem can also be restarted to restore the network communication function of the modem, the operation is simple, and the recovery efficiency of the network communication function is high.

In the embodiment of the present invention, when the network communication function of the modem is abnormal, the network connection between the modem and the current cell can be directly disconnected, and the current cell can be set as a prohibited cell, so as to avoid the modem repeatedly trying to establish a communication connection with the current cell ,Consume resources. Further, other cells corresponding to the wireless access technology supported by the modem can be searched again, the target cell can be selected from other cells, the communication connection between the modem and the target cell can be established, and the network communication function of the modem can be restored, thereby improving the recovery efficiency of the network communication function .

Further, in some feasible implementation manners, the modem may also preset a monitoring duration of the network communication function of the modem. If within the monitoring period, the modem has network communication function abnormalities many times, the network connection between the modem and the current cell can be disconnected, and the current cell can be set as a prohibited cell. If the network communication function is abnormal for many times within the monitoring period, then disconnect the network connection with the current cell, which can avoid the current cell being wrongly banned and affecting the modem when other factors cause the modem’s network communication function to be abnormal. Restoration of the network communication function.

In some feasible implementation manners, the modem may pre-establish a forbidden cell information list and store the list in a designated storage space (such as a non-volatile storage space of the UE). After the modem sets the current cell as a forbidden cell, it can record the identification information of the current cell in the above-mentioned forbidden cell information list, so as to store the identification information of the forbidden cell in the above-mentioned designated storage space. Wherein, the above-mentioned identification information of the current cell may be location information of the current cell. The above location information represents an identifier of a pre-planned logical location in the mobile communication network. The above location information may include cell ID (Cell Identity, CID), location area code (location area code, LAC) and tracking area code (Tracking area code, TAC), etc., which can be determined according to the requirements of actual application scenarios, and will not be discussed here. limit.

In a specific implementation, when the forbidden cell is released, the identification information of the forbidden cell may be cleared from the forbidden cell information list. After the modem releases the forbidden cell, it can re-search for the cell corresponding to the RAT it supports. At this point, in the current scenario, if the previous problems in the forbidden cell have been repaired, and if the modem finds the previous forbidden cell through search, it can try to access the cell again to restore the network communication function of the modem.
