Detailed Description
The embodiment of the invention provides a method for reestablishing data connection, terminal equipment and a computer readable storage medium, which are used for improving the probability of successful data connection recovery.
In order that those skilled in the art will better understand the present invention, reference will now be made to the accompanying drawings in which embodiments of the invention are illustrated, it being apparent that the embodiments described are only some, but not all, of the embodiments of the invention. Based on the embodiments of the present invention, it should be understood that the present invention is within the scope of protection.
Any data interaction with the network on the Android terminal device needs to be performed after the data connection corresponding to the access point name (Access Point Name, APN) is established successfully. For example, the mobile data transmission corresponds to a default (default) type APN, and the multimedia messaging service (Multimedia Messaging Service, MMS) type APN corresponds to a multimedia messaging service. The AP side is generally required to initiate a data connection request for establishing a corresponding APN type before data transmission, and the APN information and the request are issued to the BP side through a data connection configuration (setup data call) of the radio interface layer (Radio Interface Layer, RIL). If on long term evolution (Long Term Evolution, LTE) or ENDC (Evolved-UMTS Terrestrial Radio Access-New Radio (Evolved UMTS (Universal Mobile Telecommunications System, universal mobile telecommunications system) terrestrial Radio access-New Radio)) Dual Connectivity,4G and 5G dual connectivity), a packet data network (Packet Data Network, PDN) connection request (PDN CONNECTIVITY REQUEST) is initiated to the network end, and a default Evolved packet system (Evolved Packet System, EPS) bearer context request (ACTIVATE DEFAULT EPS BEARER CONTEXT REQUEST) is re-activated; if on a stand alone networking (SA) NR, a protocol data unit (Protocol Data Unit, PDU) session establishment request is initiated (PDU SESSION ESTABLISHMENT REQUEST). Normally, the network replies and activates the default EPS bearer context response (ACTIVATE DEFAULT EPS BEARER CONTEXT ACCEPT), or the PDU session establishment response (PDU SESSION ESTABLISHMENT ACCEPT), then transmits the corresponding information to the RIL, and finally feeds back to the AP side upper layer data connection (data call) that the establishment is successful, and the related data can be transmitted.
Android has a reestablishment mechanism, if there is a local release (local release), PDN connection rejection (PDN CONNECTIVITY REJECT)/EPS context rejection (EPS CONTEXT REJECT)/PDU session rejection (PDU SESSION REJECT) carrying the cause (cause), or when there is an abnormal disconnection of the data connection (data call), the corresponding setup data call request is reinitiated after a certain time until the data call is established successfully, and reestablishment is stopped (retry).
When encountering some special exceptions, these problems are generally caused by incompatibility between User Equipment (UE) and a network, imperfect BP design or incomplete communication design between BP and AP, and the data call cannot be recovered by using the Android default retry mechanism.
The method provided by the embodiment of the invention is applied to the Android terminal equipment. A method capable of automatically recovering data connection is provided based on an Android default retry mechanism. Under the condition that the original method cannot recover the data call, firstly, trying to reconstruct the data connection for a plurality of times after a period of time, if the data connection is not recovered, then, disconnecting the network and searching the network again after a period of time, and reconstructing the data connection again; if the data connection is not restored, the data connection is rebuilt by switching the flight mode after the last period of time, so that the probability of successful restoration of the data connection is improved.

By way of example, and not limitation, in embodiments of the present application, the terminal device may also be a wearable device. The wearable device can also be called as a wearable intelligent device, and is a generic name for intelligently designing daily wear by applying wearable technology and developing wearable devices, such as glasses, gloves, watches, clothes, shoes and the like. The wearable device is a portable device that is worn directly on the body or integrated into the clothing or accessories of the user. The wearable device is not only a hardware device, but also can realize a powerful function through software support, data interaction and cloud interaction. The generalized wearable intelligent device includes full functionality, large size, and may not rely on the smart phone to implement complete or partial functionality, such as: smart watches or smart glasses, etc., and focus on only certain types of application functions, and need to be used in combination with other devices, such as smart phones, for example, various smart bracelets, smart jewelry, etc. for physical sign monitoring.
In the following, by way of example, the technical solution of the present application is further described, as shown in fig. 1, which is a schematic diagram of an embodiment of a method for reconstructing a data connection in an embodiment of the present application, and may include:
101. and under the condition that the terminal equipment detects the disconnection, initiating a first reestablishment data connection request.
Optionally, the breaking network includes: local release (local release), packet data network PDN connection rejection, evolved packet system EPS context rejection, protocol data unit PDU session rejection, or baseband anomaly, etc.
It is understood that a disconnection can be understood as a terminal device detach (detach).
Illustratively, the BP side local release, cause is reported to the AP side of the terminal device by the network PDP reject, PDN reject, PDU reject, or other abnormal disconnect PDP, PDN, PDU.
The initiating the first request for reestablishing the data connection when the terminal device detects the disconnection may include, but is not limited to, the following implementation manners:
(1) And under the condition that the terminal equipment detects the disconnection, if a preset protocol is not available for defining a timer and a recovery mode, initiating a first reestablishment data connection request.
(2) And under the condition that the terminal equipment detects the disconnection, a first reestablishment data connection request is initiated through a first time period.
(3) And under the condition that the terminal equipment detects the network disconnection, if a preset protocol is not available for defining a timer and a recovery mode, initiating a first reestablishment data connection request through a first duration.
For example, if the terminal device detects a network outage, it determines whether there are a protocol specification timer (timer) and a reestablishment recovery PDP, PDN, PDU mode, and if so, it can recover the data connection according to the protocol specification timer and the reestablishment recovery PDP, PDN, PDU mode; if not, namely the network is disconnected in a non-protocol specification, a first reestablishment data connection request is initiated, or the first reestablishment data connection request is initiated through a first time.
102. And under the condition that the data connection is not restored according to the first reestablishment data connection request, the terminal equipment performs network disconnection and network searching, and initiates a second reestablishment data connection request.
In the case that the data connection is not restored according to the first request for reestablishing the data connection, the terminal device performs network disconnection and network searching, and initiates a second request for reestablishing the data connection, which may include, but is not limited to, the following implementation manners:
(1) And under the condition that the data connection is not restored according to the first reestablishment data connection request, if a preset protocol is not available for defining a timer and a restoration mode, the terminal equipment performs network disconnection and network searching, and initiates a second reestablishment data connection request.
(2) And under the condition that the data connection is not restored according to the first reestablishment data connection request, the terminal equipment performs network disconnection and network searching after a second duration, and initiates a second reestablishment data connection request.
(3) And under the condition that the data connection is not restored according to the first reestablishment data connection request, if a timer and a restoration mode specified by a preset protocol do not exist, the terminal equipment performs network disconnection and network searching for a second duration, and initiates a second reestablishment data connection request.
The terminal device judges whether the data call is successful or not according to the first reestablishment data connection request at the AP side, if yes, the data connection is ended, if not, whether a protocol specification timer (timer) and a reestablishment recovery PDP, PDN, PDU mode exist at the current disconnection, and if yes, the data connection can be recovered according to the protocol specification timer and the reestablishment recovery PDP, PDN, PDU mode; if not, the terminal equipment automatically cuts off the network and searches for the network, completes the network residence flow and retries to initiate the second reestablished data connection request, or after a second duration, the terminal equipment automatically cuts off the network and searches for the network, completes the network residence flow and retries to initiate the second reestablished data connection request.
It will be appreciated that after the handset is loaded into the SIM card, the handset is typically not immediately called on, but rather undergoes a short "signal search" process. When the signal icon of the operator appears on the top of the mobile phone, normal communication can be performed. This short "search signal" action, in essence, involves cell search, reading system broadcast and network side registration. The process ends with the appearance of a signal identity on the handset indicating that the UE is camping on the cell at this time and that subsequent UEs can perform a service operation in the cell. Cell search is a very critical step in a mobile communication system and is also the first step in establishing a communication link between a terminal and a network side. The purpose of cell search is to ensure that the terminal device obtains time and frequency synchronization of the system, so as to be able to read system information (cell Identification (ID) number, system bandwidth, other cell broadcast information, etc.) and perform subsequent data transmission.
In the application of the mobile communication system, after the terminal device is started, a suitable cell (such as the cell with the largest power measured from the radio frequency connector) must be searched as soon as possible, and then the cell is synchronized with the cell in time slot and frequency, so that the detailed information of the cell can be obtained. The terminal device can use the services of the network only after logging into the cell. The process from power-on search to log in to the appropriate cell is generally defined as the initial cell search (initial cell search) process, abbreviated as initial cell search. Synchronization is a key step in the initial search of a cell, and refers to the process from power on to time synchronization and frequency synchronization with the cell.
The LTE cell search procedure is as follows:
1. the UE completes the downlink synchronization procedure using PSS (Primary Synchronization Signal ) and SSS (Secondary Synchronization Signal, secondary synchronization signal).
Acquiring physical layer cell ID and time slot synchronization through PSS; and acquiring the CP (Cyclic Prefix) length, the physical layer cell group ID and the frame synchronization through SSS.
2. Time and frequency synchronization and channel estimation are further realized through DL RS (Reference Signal).
3. The PBCH (Physical Broadcasting Channel, physical broadcast channel) is decoded to obtain MIB (Master Information Block ) containing common antenna port number, SFN (System Frame Number ), downlink system bandwidth, PHICH (Physical Hybrid ARQ Indicator Channel, physical hybrid automatic repeat request (Hybrid Automatic Repeat reQuest, HARQ) indicator channel) configuration information.
4. The PDSCH (Physical Downlink Shared Channel ) is decoded to obtain SIBs (System Information Block, system information block), i.e., other system information.
Optionally, under the condition that the terminal device does not recover the data connection according to the first reestablishment data connection request, the terminal device outputs the indication information of the first data connection failure, performs network disconnection and network searching, and initiates the second reestablishment data connection request.
Optionally, the terminal device outputs the indication information of the first data connection failure in a text, voice or picture mode.
103. And ending the recovery data connection under the condition of recovering the data connection according to the second recovery data connection request.
The terminal device determines whether the data call is successful according to the second request for reconstructing the data connection at the AP side, and if yes, ends the recovery of the data connection.
Optionally, when the terminal device resumes the data connection according to the second request for resuming the data connection, the resuming the data connection is ended, and the terminal device outputs the indication information that the first data connection is successful.
Optionally, the terminal device outputs the indication information of successful connection of the first data in a text, voice or picture mode.
104. And under the condition that the data connection is not recovered according to the second reestablished data connection request, switching the flight mode by the terminal equipment to search the network, and initiating a third reestablished data connection request.
In the case that the data connection is not recovered according to the second request for reconstructing the data connection, the terminal device switches the flight mode to search the network, and initiates a third request for reconstructing the data connection, which may include, but is not limited to, the following implementation manners:
(1) And under the condition that the data connection is not restored according to the second reestablished data connection request, if a preset protocol is not available for defining a timer and a restoration mode, switching a flight mode of the terminal equipment to search the network, and initiating a third reestablished data connection request.
(2) And under the condition that the data connection is not recovered according to the second reestablished data connection request, switching the flight mode of the terminal equipment to search the network after a third duration, and initiating a third reestablished data connection request.
(3) And under the condition that the data connection is not restored according to the second reestablished data connection request, if a preset protocol is not available for defining a timer and a restoration mode, switching a flight mode of the terminal equipment to search the network, and initiating a third reestablished data connection request.
The terminal device judges whether the data call is successful or not according to the second reestablishment data connection request at the AP side, if not, judges whether the current disconnected network has a protocol specification timer (timer) and a reestablishment recovery PDP, PDN, PDU mode, and if so, can recover the data connection according to the protocol specification timer and the reestablishment recovery PDP, PDN, PDU mode; if not, the terminal device performs an automatic switching flight mode, performs network searching to complete a network residence process, and retries to initiate a third reestablished data connection request, or performs an automatic switching flight mode, performs network searching to complete the network residence process, and retries to initiate the third reestablished data connection request after a third duration.
It can be understood that the flight mode of the mobile phone is called aviation mode, and when taking the airplane, the mobile phone must be turned off or the own flight mode of the mobile phone must be turned on to cut off all communication signals, so as to avoid the influence of the emission and the reception of the mobile phone signal on the airplane flight, and some mobile phones have the function and can turn off the signal transceiver of the subscriber identity module (Subscriber Identity Module, SIM) card.
Some of the functions of the mobile phone in the flight mode can be implemented by some software, for example, the System tools (systems) in the S60 software have the aviation mode. The mode can turn off the SIM card function, so that the mobile phone is in a state of not transmitting and receiving signals, and other functional operations of the mobile phone are not affected (generally, the mobile phone cannot perform any operation without the SIM card).
The flight mode turns off the GSM (Global System for Mobile Communications )/GPRS (General packet radio service, general packet radio service) module of the handset, which does not actively send paging signals to the base station, i.e., does not attempt to contact the base station, but typically dials an emergency call (similar to the SIM card-less principle, in which mode the handset typically dials 110, 120, 112, etc.). Because the mobile phone paging signal can interfere with the electronic equipment on the airplane, the airplane is not allowed to turn on the mobile phone, and related functions of the mobile phone signal are turned off in the mode, the mobile phone can continue to use other functions, such as checking a phone book, enjoying articles, movies, playing games and the like on the mobile phone, so that the airplane is called a flight mode. The electric quantity of the mobile phone is mostly consumed on the signal, and the signal is turned off in the flight mode, so that the power is saved.
Optionally, when the terminal device does not recover the data connection according to the second reestablished data connection request, the terminal device outputs indication information of the failure of the second data connection, switches the flight mode to search the network, and initiates a third reestablished data connection request.
Optionally, the terminal device outputs the indication information of the second data connection failure in a text, voice or picture mode.
105. And ending the recovery data connection under the condition of recovering the data connection according to the third reconstruction data connection request.
The terminal device, on the AP side, determines whether the data call is successful according to the third reestablished data connection request, and if yes, ends the recovery data connection.
Optionally, when the terminal device resumes the data connection according to the third reestablished data connection request, the data connection is ended, and the terminal device outputs the indication information that the second data connection is successful.
Optionally, the terminal device outputs the indication information of successful connection of the second data in a text, voice or picture mode.
It can be appreciated that the long term evolution (Long Term Evolution, LTE) power-on and network-down procedure may include:
Whether the LTE terminal equipment supports Long Term Evolution Voice-Term Evolution (VoLTE) is not considered temporarily, and even if the LTE terminal equipment supports the VoLTE, the premise of registration of the VoLTE is that the LTE is registered first. LTE power-on registration can be divided into the following steps:
1. a random access process, obtaining wireless resources for signaling interaction between terminal equipment and EPC;
2. interaction such as Attach request (Attach request), identity (Identity), authentication (Authentication), security (Security), attach Accept (Attach Accept), attach complete (Attach complete) and the like between the terminal device and the EPC;
3. if both the terminal equipment and the EPC support VoLTE, the process of LTE Attach also includes a P-CSCF Discovery (Proxy Call Session Control Function, call session control proxy) process.
In the embodiment of the application, under the condition that the terminal equipment detects the disconnection, a first reestablishment data connection request is initiated; under the condition that the data connection is not restored according to the first reestablishment data connection request, the terminal equipment performs network disconnection and network searching, and initiates a second reestablishment data connection request; and ending the recovery data connection under the condition of recovering the data connection according to the second recovery data connection request. After the embodiment of the application is applied, when the terminal equipment is disconnected, the data connection can be rebuilt through an Android default mode, then the network is searched again through the disconnected network, the data call is rebuilt, and the probability of successful data connection recovery is improved.
As shown in fig. 2, a schematic diagram of another embodiment of a method for reconstructing a data connection in an embodiment of the present application may include:
step1, the BP side local release of the terminal device, the local release of the terminal device by the network PDP, PDN, PDU reject, or other abnormal disconnection PDP, PDN, PDU mode, and report to the AP side of the terminal device.
Step2, the terminal equipment judges whether the current disconnection has a protocol specification timer (timer) and a reconstruction PDP, PDN, PDU mode, if yes, step3 is executed, and otherwise Step4 is executed.
Step3, the terminal equipment rebuilds and initiates a data call according to the protocol specification timer and a rebuilding PDP, PDN, PDU mode.
Step4, after a period of time t1, the terminal equipment re-initiates a data call reestablishing request by using an Android default method.
Step5, the terminal equipment judges whether the recovery of the data call is successful or not at the AP side, if yes, the recovery is ended, and otherwise, step6 is executed.
Step6, the terminal equipment judges whether the current disconnection has a protocol specification timer and a reconstruction PDP, PDN, PDU mode, if yes, step3 is executed, and otherwise Step7 is executed.
Step7, after a period of time t2, the terminal equipment automatically breaks the network and searches the network again, so as to complete the network residence process and re-attempt to establish the data call.
Step8, the terminal equipment judges whether the recovery of the data call is successful or not at the AP side, if yes, the recovery is ended, and otherwise Step9 is executed.
Step9, the terminal equipment judges whether the current disconnection has a protocol specification timer and a reconstruction PDP, PDN, PDU mode, if yes, step3 is executed, and otherwise Step10 is executed.
Step10, after a period of time t3, the terminal equipment automatically switches on and off the flight mode, searches the network again, completes the network residence flow and retries to establish the data call.
Step11, the terminal equipment judges whether the recovery of the data call is successful or not at the AP side, if yes, the recovery is ended, and otherwise, step2 is executed.
Illustratively, t1, t2, t3 may be 10s.
In the prior art, any data interacted with a network on an Android terminal device can be transmitted only after the data connection corresponding to an APN is established successfully. When a local release, a ca-carrying PDN CONNECTIVITY REJECT/EPS CONTEXT REJECT/PDU SESSION REJECT occurs, or there is an abnormal disconnection of the data connection, the default retry mechanism will reinitiate the establishment of the data connection after a certain period of time until the establishment is successful, but the mechanism cannot recover from some special exceptions. The invention provides a method capable of automatically recovering data connection based on an Android default retry mechanism for solving the problem that an Android mobile phone possibly has the problem.
In the embodiment of the application, the hardware structure is not required to be modified. When the terminal equipment is disconnected, if the terminal equipment is judged to be disconnected according to the non-protocol specification, the data call can be rebuilt through Android defaults, if the data connection is not restored, then after a period of time, the network is rebuilt through disconnected again, the data call is rebuilt, if the data connection is not restored yet, then after a period of time, the flight mode is switched on again, and the mode of rebuilt data call is restored. The scheme can simulate special modes such as a user carrying terminal equipment to leave a problem cell, a manual switching flight mode and the like to avoid the problems of incompatibility between the terminal equipment and a network, imperfect BP design or incomplete communication design between the BP and the AP, reduce the condition of no recovery of a long-time discontinuous network, and further improve the probability of successful data connection recovery.
