Technical Field

The present application relates to the field of communications technologies, and in particular, to a communications method and related devices.

Background

When the configuration of a cell base station accessed by the terminal equipment is abnormal, or the configuration of the routing equipment is abnormal, or the software of the terminal equipment is wrong, the corresponding protocol related to the service of the terminal equipment cannot be normally used, and at the moment, the terminal equipment can reset the protocol subsystem related to the service. However, when the subsystem is reset, the service corresponding to the subsystem is temporarily closed, and the service interruption affects the user experience.

Therefore, service shutdown caused by subsystem reset is a problem to be solved.

Disclosure of Invention

In view of the above, the present application provides a communication method and related devices. After the terminal equipment enters the problem cell, subsystem reset is performed, so that the problem that the terminal equipment service is temporarily closed is avoided, and the user experience is improved.

In a first aspect, a communication method is provided, which includes: the first terminal equipment resides in a first cell to carry out data transmission service; detecting that a first terminal device meets a cell switching condition, and acquiring cell information of a cell to be resided, which meets a residency condition; determining whether a first type of cell exists in the cells to be resided or not based on the acquired cell information, wherein the first type of cell is a cell in which the communication subsystem reset does not occur in both the first terminal and the second terminal equipment; and the first terminal equipment is switched to carry out data transmission service through the second cell corresponding to the second cell belonging to the first type cell in the cells to be resided.

In the above scheme, the terminal detects whether the communication subsystem is reset before the terminal detects the cell before the cell is resided in the handover, and when the terminal detects that a plurality of cells meeting the residency condition exist, the terminal preferentially residents the cell which is not reset by the communication subsystem, namely the non-problem cell. Therefore, the problem that the subsystem is reset after the terminal equipment enters the problem cell is avoided, the problem that the service of the terminal equipment is temporarily closed is avoided, and the user experience is improved.

With reference to the first aspect, in some implementations, the cell information includes a cell identifier of each cell to be camped, and when the cell identifier of at least one cell to be camped does not exist in preset cell information, the first terminal device determines that a first type of cell exists in the cells to be camped, where the preset cell information includes a cell identifier of a cell in which the first terminal device or the second terminal device has undergone a reset of the communication subsystem.

In the above scheme, the preset cell is a cell in which the communication subsystem is reset, and when the cell meeting the residence condition is not in the preset cell information, it is indicated that the cell meeting the residence condition has a non-problem cell. Therefore, through constructing preset cell information, the terminal equipment can be prevented from residing in a problem cell, further the problem that the subsystem of the terminal equipment is reset and the service of the terminal equipment is temporarily closed is prevented, and the experience of influencing users is improved.

In combination with the first aspect, in some implementations, the first terminal device switches to a third cell to perform data transmission service in a low format, where the third cell does not meet the camping condition, where the cells to be camped do not belong to the first type cell and all the cells to be camped meet the preset condition; corresponding to the cells to be resided which do not belong to the first type of cells, wherein the cells to be resided comprise fourth cells which do not meet preset conditions, and the first terminal equipment is switched to perform data transmission service through the fourth cells; the preset conditions comprise: the accumulated number of times that the first terminal equipment and the second terminal equipment reset the communication subsystem in the cell to be resided is larger than the preset number of times; and/or the accumulated times of the first terminal equipment and the second terminal equipment for resetting the communication subsystem in the cell to be resided are larger than the preset ranking in the accumulated times corresponding to each cell in the preset cell information.

In the above scheme, the method further determines a blacklist cell and/or a low priority cell according to the number of times that each cell performs subsystem reset, where the blacklist cell is a problem cell meeting a preset condition, the low priority cell is a problem cell not meeting the preset condition, and the number of times that the blacklist cell performs the communication subsystem reset is greater than the number of times that the low priority cell performs the communication subsystem reset. When the cell meeting the residence condition is only a blacklist cell, the terminal equipment reduces the network system of the terminal equipment to reside the non-problem cell according to the network system of the non-problem cell which does not meet the residence condition. When the cell satisfying the camping condition has no non-problem cell but there is a low priority cell, the terminal device camps on the low priority cell. Therefore, the problem that the terminal equipment is resided in a blacklist cell where the communication subsystem is reset frequently is avoided, the subsystem is prevented from being reset, the service of the terminal equipment is temporarily closed, and the experience of a user is improved.

In combination with the first aspect, in some implementations, when the cells to be camped determined by the first terminal device continuously for N times all meet the preset condition and all include the fifth cell, the cell on which the first terminal device resides is not changed within a preset duration, where N is greater than or equal to 2, and the preset duration increases with the increase of N.

In the above scheme, when the terminal device detects that the cells meeting the residence condition are all blacklist cells, the terminal device can also detect whether the cells meeting the preset condition are only blacklist cells or not again every preset time, so that the situation that the terminal device is accidentally detected that the cells are all blacklist cells can be avoided, and the network system of the terminal device is reduced for a long time for data transmission. If the terminal equipment continuously detects that only the blacklist cell exists, the preset time length is gradually increased, and the terminal equipment keeps the low system for a longer time to stay in the cell. Therefore, after the terminal equipment detects for many times, the terminal equipment can keep the low system for a long time only when the blacklist cell meets the residence condition. The communication quality of the user is ensured, and the experience of the user is improved.

With reference to the first aspect, in some implementations, detecting that the first terminal device generates a communication subsystem reset, updating a cell identifier of a sixth cell to preset cell information, where the sixth cell is a cell where the first terminal device currently resides; and the first terminal equipment uploads the cell identification of the sixth cell and the cell information of the cell to be resided to the server corresponding to that the first terminal equipment does not generate communication subsystem reset.

In the above scheme, after the terminal device resides in the cell, it is also monitored whether the terminal device generates a subsystem reset. If the terminal device is subjected to subsystem reset, the terminal device updates the information of the problem cell. If the terminal equipment does not generate subsystem reset, the optimization measures are reported to the server. Therefore, when other terminal equipment reenters the cell to be resided, the cell to be resided can be switched directly according to the optimization measures, and the efficiency of the terminal equipment for switching the cell to be resided is improved.

With reference to the first aspect, in some implementations, the third terminal device obtains, from a server, cell information of a cell to be camped on and a cell identifier of a sixth cell; and when the third terminal equipment determines that the cell information meeting the residence condition is the same as the cell information of the cell to be resided, switching to a sixth cell for data transmission.

In the scheme, when other terminal equipment reenters the cell to be resided, the resident cell can be switched directly according to the optimization measures, so that the efficiency of the terminal equipment for switching the resident cell is improved.

With reference to the first aspect, in some implementations, the first terminal device and the second terminal device are the same; or the first terminal device and the second terminal device are different.

In the above scheme, the terminal device may enter the same cell range to be camped for multiple times, and the result of selecting the camped cell in the cell to be camped and whether subsystem reset occurs will also be uploaded to the database for use by itself or other terminal devices.

In a second aspect, the application provides an electronic device comprising a processor and a memory, the memory being for storing instructions, the processor being for executing instructions which, when executed by the processor, perform a method as described in the first aspect.

In a third aspect, the application provides a computer readable storage medium having instructions stored therein which, when run on an electronic device, perform a method as described in the first aspect.

In a fourth aspect, the present application provides a computer program product comprising computer instructions which, when executed by a computing device, performs a method as described in the first aspect.

In summary, according to the terminal device communication method and the related device provided by the application, the terminal device can acquire the information of the problem cell which is frequently subjected to subsystem reset from the database, when the terminal device approaches the problem cell, whether the problem cell resides or not is determined in advance, and if the problem cell cannot reside, the cell to reside is determined in the adjacent cell. After the terminal equipment enters the problem cell, subsystem reset is avoided, so that the terminal equipment service is prevented from being temporarily closed, and the user experience is improved. And the terminal equipment can upload the optimization measures to the database, so that other terminal equipment can directly optimize according to the optimization measures, the cell type is not required to be judged according to the number of times of resetting the cell subsystem, and the optimization strategy is determined, so that the judgment time before the terminal equipment resides in the network is saved, and the equipment cost is saved.

Detailed Description

Illustrative embodiments of the application include, but are not limited to, terminal device communication methods and related devices.

For easy understanding, the concept of the cell according to the embodiment of the present application will be described below with reference to the accompanying drawings.

In a mobile communication system, an area covered by a base station or a part of a base station (for example, a sector antenna) is a cell, and in this area, a terminal device may communicate with the base station through a radio channel. In the radio coverage area (cell) of the base station, the base station may interact with the terminal equipment through a mobile communication switching center (e.g., network requests and interactions that require the use of a mobile network, such as making a call, 2G/3G/4G/5G internet, etc.).

Understandably, the terminal device can detect the signal of the cell while it is within the coverage area of the cell signal. One cell may have one or more adjacent cells, when the terminal device is located in the coverage overlapping range of the signals of the cells, the terminal device may access the target cell meeting the residence condition from the cells, and further send a request to the base station to establish the data connection between the terminal device and the target cell, or access the cell through the routing device, so as to realize the residence network of the terminal device, so that the target cell provides services such as communication, surfing the internet, and the like for the terminal device. Similarly, a switching relationship can be set between a cell and a neighboring cell of the cell, when the terminal equipment moves from the current cell to the neighboring cell and the neighboring cell also accords with the residence condition, the terminal equipment can be switched from the current cell to the neighboring cell according to the movement direction of the terminal equipment when moving to the overlapping range covered by the signals of the current cell and the neighboring cell, so that the service of the terminal equipment can be smoothly switched in the moving process, and the communication is not interrupted.

As shown in fig. 1, the neighboring cells of cell a include cell B, cell C, and cell D. When the terminal equipment is in the overlapping area of the coverage areas of the base stations of the cell A and the cell B, the base station signals of the cell A and the cell B can be searched. Cell a and cell B both meet the camping conditions of the terminal device, and when the terminal device moves from cell a to the center of cell B, the terminal device can be handed over from camping cell a to camping cell B.

When the configuration of the base station accessed by the terminal equipment is abnormal, or the configuration of the routing equipment is abnormal, or the program error of the terminal equipment software is generated, the corresponding protocol related to the terminal equipment service cannot be normally used, for example, the modulation protocol (modulation protocols), the wireless protocol, the Bluetooth transmission protocol and the like cannot be normally used, so that the terminal equipment cannot perform the service related to the protocol. At this time, the terminal device may reset a protocol subsystem related to the service, for example, a modem (modem) subsystem reset, a Wi-Fi subsystem reset, a Bluetooth (BT) subsystem reset, a location based service (location based services, LBS) subsystem reset, a near field communication (near field communication, NFC) subsystem reset, and further reset the subsystem, so that the service corresponding to the subsystem is autonomously recovered.

However, during the resetting process of the subsystem, the related service of the subsystem is not normally used. For example, when the modem subsystem is reset, the modem stops working, and at this time, the terminal equipment can have the conditions of network drop, card drop, no signal and the like; when the Wi-Fi subsystem is reset, the terminal equipment can be disconnected with the Wi-Fi; when the Bluetooth subsystem is reset, the Bluetooth connection of the terminal equipment is disconnected; when the LBS subsystem is reset, the terminal equipment can have positioning failure; when the NFC subsystem is reset, NFC related services cannot be used, for example, access control fails.

That is, when the network configuration of a part of cells is abnormal, or when a software program error or a hardware problem is often generated after the terminal device enters a part of cells, the terminal device automatically resets the corresponding subsystem to restore the operation of the service. However, when the subsystem is reset, the service corresponding to the subsystem is temporarily closed, and the service interruption affects the user experience.

In order to solve the problem that the service cannot normally run due to the reset of a subsystem of a terminal device, the application provides a communication method, which is characterized in that the cell information (such as a cell identifier) of a cell (hereinafter referred to as a problem cell) of which the subsystem is reset by the terminal device is recorded, so that when the terminal device selects or switches the resident cell, the cell information of the cell meeting the resident condition is compared with the recorded cell information, when the resident condition is met by the problematic cell and the non-problematic cell, the terminal device preferentially resides in the non-problematic cell, and when the resident condition is met by the problematic cell only, the terminal device determines whether to reside in the non-problematic cell or the non-problematic cell in a low mode according to the number of times that the subsystem reset occurs to the problematic cell. Therefore, the phenomena of network drop, card drop, no signal and the like of the terminal equipment due to subsystem reset can be avoided, and the user experience is improved.

It is understood that the resident conditions may include, but are not limited to: the public land mobile network (public land mobile network, PLMN) of the cell is a PLMN selected by the network attached storage (network attached storage, NAS), the PLMN of the cell being a registered PLMN; the cell is not a forbidden cell; the tracking area identity (tracking area identifier, TAI) of the cell is not a TAI in the list of tracking areas for roaming barring; the cell meeting cell selection criteria (cell selection criteria); the cell network system is matched with the network system of the terminal equipment.

It can be understood that the network system of the non-problem cell is not matched with the high network system of the current terminal device by the low-system residence, so that the terminal device can reduce the network system thereof to match with the low network system of the non-problem cell so as to residence the non-problem cell of the low network system.

Specifically, as shown in fig. 2, the method is applied to the terminal device 10, the database 20 and the terminal device 30 in fig. 2, when the terminal device 10 generates a protocol subsystem reset, the terminal device 10 can report the information of generating a subsystem reset in the current cell to the database 20, the database 20 can store the information of generating a subsystem reset of each terminal device 10, determine the cell subjected to the subsystem reset as a problem cell, rank the cells according to the number of times of carrying out the subsystem reset of each cell, and determine the type of the cell, such as a blacklist cell and a low priority cell. Further, the terminal device may acquire the cell information of the database 20, and when switching the camping cell, determine whether the cell meets the camping condition, and further determine whether the cell is a problem cell, and further determine whether to camp on the cell or other cells. If the cell is a problem cell, the terminal device also records the determination result and the cell to be camped as optimization measures, and uploads the result and the cell to be camped as optimization measures to the database 20. The database 20 will record the optimisation measures in the cell information and the terminal device, when entering or approaching the problem cell, can directly select the cell where it needs to camp according to the optimisation measures. That is, the cell information stored in the database 20 includes the number of times that the respective cell occurrence protocol subsystem is reset and the optimization measures of the problem cell.

For example, the terminal device 30 can obtain the cell information of the database 20, and determine whether the terminal device 30 is camping on the problematic cell according to the cell information in the database 20 if the cell to be entered by the terminal device 30 is the problematic cell and the problematic cell meets the camping condition during the movement of the terminal device 30. When the problem cell is a blacklist cell, if the terminal device 30 detects other cells meeting the residence condition, the terminal device 30 directly resides in the cell, and if the terminal device 30 does not detect other cells meeting the residence condition, the terminal device 30 reduces own network system according to network systems of other surrounding cells, and then resides in other cells. If the problem cell is a low priority cell, the terminal device 30 will camp on other cells if the terminal device 30 detects other cells satisfying the camping condition, and if the terminal device 30 does not detect other cells satisfying the camping condition, the terminal device 30 will camp on the low priority cell.

The terminal device 30 also records the results of determining whether to camp on the problem cell, determining the cell to camp on in the neighboring cells, and the like as an optimization measure, and uploads the optimization measure to the database 20, and the database 20 records the optimization measure in the cell information, so that other devices can directly select the cell to camp on according to the optimization measure when determining whether to camp on the problem cell. When other devices perform processing according to the optimization measures, the situation that the subsystem needs to be reset still occurs, and the other devices also upload the result of the optimization failure to the database 20, so that the database 20 updates the optimization measures. Details of the communication method will be described in detail later, and will not be described here.

In this way, the terminal equipment can acquire the problem cell information needing subsystem reset, before the terminal equipment camps on the problem cell, whether the problem cell is camped or not can be determined according to the cell information, and if the problem cell cannot be camped, the cell to be camped is determined in the adjacent cells. After the terminal equipment enters the problem cell, subsystem reset is performed, so that the problem that the terminal equipment service is temporarily closed is avoided, and the user experience is improved.

It should be understood that the terminal device 30 may upload information such as an Access Point (AP) or a routing device, in addition to uploading cell information. For example, after the terminal device 10 accesses the AP and performs a subsystem reset, the terminal device 10 may upload information that the subsystem reset occurs in the AP, and the database 20 stores the information in units of the AP. Alternatively, after the terminal device 10 accesses the routing device and performs the subsystem reset, the terminal device 10 may upload information that the subsystem reset has occurred in the routing device, and the database 20 may store the information in units of the routing device. That is, the present application is not particularly limited as to whether the cell information, the AP information, the routing device information, or the information of other network devices are stored in the database 20. Hereinafter, for convenience of description, the method of storing other location information will be described with reference to the method of storing cell information, taking the example that the database 20 stores cell information.

The terminal device 10 and the terminal device 30 are electronic devices having a communication function, and may specifically be a mobile phone, a tablet computer, a wearable device, a vehicle-mounted device, a notebook computer, a smart watch, an ultra-mobile personal computer (UMPC), a netbook, an AR/VR device, a personal digital assistant (personal digital assistant, PDA), a special camera (e.g., a single-lens reflex camera, a card-type camera), or the like. The structures of the terminal device 10 and the terminal device 30 will be described in detail later with reference to fig. 3, and will not be described again here.

The database 20 may be a physical server or cloud device, such as an X86 server, an ARM server, or the like, or may be a Virtual Machine (VM) implemented by combining a general-purpose physical server with a network function virtualization (Network Functions Virtualization, NFV) technology, where the VM refers to a complete computer system that is simulated by software and has a complete hardware system function and operates in a completely isolated environment, which is not limited in the present application.

In some embodiments, the database 20 may be deployed in an edge environment or in a cloud environment. The edge environment may specifically be one edge computing device in the edge environment or a software system running on one or more edge computing devices. An edge environment refers to a cluster of edge computing devices geographically close to the edge computing devices for providing computing, storage, and communication resources, such as edge computing all-in-one located near a cell, county-level edge servers. A cloud environment is an entity that provides cloud services to users using underlying resources in a cloud computing mode. The cloud environment includes a cloud data center including a large number of underlying resources (including computing resources, storage resources, and network resources) owned by a cloud service provider, and a cloud service platform, where the computing resources included in the cloud data center may be a large number of computing devices (e.g., servers). Such as bare metal servers of a south China cloud data center, virtual machines created in the cloud data center, servers in the cloud data center or software systems on the virtual machines, the database 20 may be distributed across multiple servers, or across multiple virtual machines, or across virtual machines and servers.

The keys 190 include a power-on key, a volume key, etc. The electronic device 100 may receive key inputs, generating key signal inputs related to user settings and function controls of the electronic device 100.

The motor 191 may generate a vibration cue.

The indicator 192 may be an indicator light, may be used to indicate a state of charge, a change in charge, a message indicating a missed call, a notification, etc.

It is to be understood that the illustrated construction of the present application does not constitute a particular limitation of the electronic device 100. In other embodiments, electronic device 100 may include more or fewer components than shown, or certain components may be combined, or certain components may be split, or different arrangements of components. The illustrated components may be implemented in hardware, software, or a combination of software and hardware.

From the above description, the cell information stored in the database 20 includes the number of times that the protocol subsystem reset occurs for each cell and the optimization measures for the problem cell. The number of cell generation protocol subsystem resets acquired by database 20 is described in detail below with reference to the accompanying figures. As shown in fig. 4, after the terminal device 10 generates the protocol subsystem reset, the current cell protocol subsystem reset information is reported to the database 20, and then the database 20 updates the cell information.

S1: a subsystem reset of the terminal device 10 occurs.

When the terminal device 10 is reset in the cell where it resides, the terminal device 10 will acquire the current location information and/or cell ID.

In some embodiments, after the protocol subsystem reset occurs, the terminal device 10 establishes a new point on the communication history (Communication History Record, CHR) for recording the information of the subsystem reset, and the CHR of the terminal device 10 can obtain whether the terminal device 10 has occurred or the subsystem is reset.

S2: the terminal device 10 uploads the current cell subsystem reset information.

The terminal device 10 uploads the location and/or cell ID of the terminal device and the information about occurrence of the subsystem reset to the database 20, so that the database 20 determines the cells subjected to the protocol subsystem reset as problem cells, and orders the cells according to the number of times of each cell subjected to the protocol subsystem reset, thereby determining blacklisted cells and/or low priority cells. In some embodiments, cells may include other types in addition to blacklisted cells and low priority cells.

The terminal device 10 may acquire the cell information in the database 20, determine whether a cell satisfying the camping condition is a problem cell before the terminal device 10 is ready to handover to a camping cell, and determine whether to camp on the problem cell, or measure the signal strength of surrounding cells, and determine a cell to camp on in a neighboring cell. The terminal device 10 will record the results of determining whether to camp on the problem cell and determining the cell to camp on in the neighboring cell as an optimizing measure, and upload the optimizing measure to the database 20, and the database 20 will record the optimizing measure into the cell information, so that other devices can directly select the cell to camp on according to the optimizing measure when entering or approaching the problem cell. The process of uploading and obtaining the optimization measures by the terminal device 10 will be described in detail below, and will not be described in detail here.

S3: the database 20 updates the cell information.

The database 20 increments the number of times the corresponding cell has been subjected to a subsystem reset according to the terminal device location and/or cell ID. The database 20 also determines the cells subjected to the protocol subsystem reset as problem cells, and sorts the cells according to the number of times each problem cell is subjected to the subsystem reset, so as to determine the types of the problem cells, for example, the types of the problem cells include a blacklisted cell and a low priority cell. When the problem cell is a blacklisted cell, the terminal device will not directly camp on the cell. If the problem cell is a low priority cell, the terminal device will measure the signal strength of the neighboring cell and determine the cell to camp on in the cell and the neighboring cell. It should be appreciated that the database 20 may store the number of times a cell has been reset by a subsystem, or may store the type of problem cell that the cell determines based on the result of the ordering of the number of times the subsystem has been reset.

In some embodiments, the database 20 may order the cells from high to low by the number of times a subsystem reset occurs, set the top-ranked N-bit problem cell as a blacklist cell, set the top-ranked n+1th to M-th problem cell as a low priority cell, N and M are positive integers, and M is greater than N. For example, 10 cells having the largest number of times of the subsystem reset may be set as blacklisted cells, and the other cells among 30 cells having the largest number of times of the subsystem reset may be set as low priority cells.

In other embodiments, the database 20 may also obtain the total number of times a cell is accessed, and determine the frequency at which the subsystem reset occurs based on the number of times the terminal device residing in the cell has undergone the subsystem reset and the total number of times it is accessed. Database 20 determines blacklisted cells and low priority cells based on the frequency at which the respective cells undergo subsystem resets. For example, if the frequency of the cell occurrence subsystem reset is 100%, the cell is a blacklisted cell, and if the frequency of the cell occurrence subsystem reset is greater than 80%, the cell is a low priority cell.

In summary, the terminal device 10 uploads the location or the cell ID of the occurrence of the subsystem reset to the database, so that the number of times of the occurrence of the subsystem reset of the cell is stored in the database 20, and the blacklisted cell and the low priority cell can be determined. Furthermore, other terminal equipment can determine the cell which can reside according to the blacklist cell and the low-priority cell list, so that the situation that the terminal equipment resides in the cell in which the subsystem reset usually occurs to cause the subsystem reset of the terminal equipment to influence the operation of the service and influence the user experience is avoided.

The communication method provided by the present application is described in detail below with reference to fig. 5. The communication method is applied to the terminal device 30, that is, fig. 5 illustrates an example in which the terminal device 30 determines a camping cell.

S501: the terminal device 30 moves to a cell that meets the camping condition.

During the moving process, the terminal device 30 can search the base station signals of a plurality of cells nearby, and the terminal device 30 will detect whether the surrounding cells meet the residence condition in real time. The terminal device 30 moves to a cell that meets the camping condition, i.e. the terminal device 30 is moving away from the base station of the currently camping cell to other base stations that meet the camping condition.

The terminal device 30 may determine that the terminal device 30 is moving to a cell that meets the camping condition by acquiring the position, specifically may periodically acquire the position information of the terminal device 30, for example, acquire the position information of the terminal device 30 once every minute by a global positioning system (Global Positioning System, GPS).

In some embodiments, the terminal device 30 may also determine the location and the moving direction of the terminal device 30 according to the information such as the signal strength of the neighboring cell detected by the terminal device 30, and when the signal strength of the base station of a certain cell detected by the terminal device 30 increases gradually, it may be determined that the terminal device 30 is approaching the base station of the cell.

In some embodiments, the terminal device 30 may both acquire the terminal device 30 location information and detect the neighboring cell signal strength in the vicinity of the terminal device 30, e.g., by detecting the neighboring cell base station signal strength in the vicinity of the terminal device 30 to determine the location and direction of movement of the terminal device 30 in the event of failure to acquire the terminal device 30 location information. It should be understood that the manner in which the terminal device 30 obtains the real-time position is not particularly limited by the present application.

S502: it is determined whether the cell is a problem cell.

When the terminal device 30 satisfies the camping cell handover condition, for example, the terminal device 30 moves to another cell that meets the camping condition, the terminal device 30 will determine whether the cell is a problem cell according to the number of times that other terminal devices have undergone a subsystem reset in the cell. If there is a terminal device that has undergone a subsystem reset in the cell, the cell is a problem cell, and the terminal device 30 will execute step S503: the type of the problem cell is determined. If no terminal device has undergone a subsystem reset in the cell, the cell is not a problem cell, and the terminal device 30 will perform step S504: camping on a cell that is approaching.

Wherein the number of times the cell has been reset by the subsystem is obtained by the terminal device 30 from the cell information in the database 20. The terminal device 30 may also be of a cell type obtained from a database, wherein the cell type is a result of the ordering according to the number of times of the subsystem reset, i.e. whether the cell is a problem cell or a non-problem cell, and if it is a problem cell, whether the problem cell is a blacklisted cell or a low priority cell, or other types of cells. Reference is specifically made to the description of step S3 in fig. 4, and no further description is given here.

The terminal device 30 may acquire the cell information in the database 20 periodically, or may acquire the cell information from the database 20 based on a user operation. For example, the terminal device 30 may acquire the cell information in the database 20 in the morning 02:00-04:00 every week, with the frequency being once every week, so as to avoid updating the cell information too frequently, and affecting the user experience.

The terminal device 30 may acquire the cell information of all the cells in the database 20, or may acquire only the cell information of the cells in the vicinity of the terminal device 30 based on the current location information of the terminal device 30 when acquiring the cell information. It should be understood that the present application is not particularly limited in terms of the time and cell range at which the terminal device 30 acquires cell information.

S503: the type of the problem cell is determined.

When the cell that the terminal device 30 is approaching is a problem cell, the terminal device 30 will further determine the type of the problem cell, in particular whether the problem cell is a blacklisted cell or a low priority cell. When the problem cell is a blacklisted cell, the terminal device will perform step S505: it is determined whether a neighboring cell is measured to be camping. When the problem cell is a low priority cell, the terminal device will perform step S508: it is determined whether a neighboring cell is measured to be camping.

S504: camping on a cell that is approaching.

When the cell that the terminal device 30 is approaching is not a problem cell and the cell also meets the camping condition of the terminal device 30, the terminal device 30 will camp on the cell.

S505: it is determined whether a neighboring cell is measured to be camping.

When the cell that the terminal device 30 is approaching is a blacklisted cell, the terminal device 30 is not camping on the blacklisted cell. Thus, the terminal device 30 will detect the signals of surrounding cells, detecting whether there are other cells that meet the camping condition. When detecting that other cells surrounding the cell-number meeting the camping condition can camp on, the terminal device 30 will execute step S506: and camping on other cells. If it is not detected that other cells around can camp on, the terminal device 30 will perform step S507: network system is reduced and other cells are resided. It should be understood that the camping conditions include network type matching of the cell base station and the network type of the terminal device 30. When no other cells in the surrounding area meet the residence condition, the terminal equipment changes own network system to determine the cell which can reside.

In some embodiments, when the cell that the terminal device 30 is approaching is a blacklisted cell, the silence period of the blacklisted cell is further calculated according to the terminal device 30 when the detected cells satisfying the camping condition are all the blacklisted cell, and when the detected cells are in the silence period, the terminal device 30 performs step S505: after determining whether the neighboring cell is measured to be camping, camping on the cell according to the determination result, when the muting duration is over, the terminal device 30 will execute step S505 again: it is determined whether a neighboring cell is measured to be camping.

Specifically, the terminal device 30 records that the number of times that the blacklisted cell meets the camping condition is identified as K, K default is 0, the silence duration may be k×x minutes, and X is a positive number. When the terminal device 30 recognizes that the blacklisted cell meets the camping condition for the first time, the K value is increased by 1, and the terminal device 30 performs step S505: and judging whether the neighboring cell can be resided or not, and resided in the cell according to the judging result. After X minutes, if the terminal device 30 remains in the blacklist cell, and if the blacklist cell still meets the camping condition, the K value is increased by 1 again, and the terminal device 30 will execute step S505 again: determining whether or not a neighboring cell is measured to be camping on, and camping on the cell according to the determination result, 2*X minutes, the terminal device 30 will repeat the above steps, and so on. Where X may be customizable, and X may take 10 minutes, for example.

S506: and camping on other cells.

When the terminal device 30 detects that other cells in the surroundings meet the camping condition, the terminal device 30 will camp on the cell directly.

S507: and reducing network type resident other cells.

When the terminal device 30 does not detect that there are cells surrounding the cell which meet the camping condition, the terminal device 30 will reduce other cells which can camp around the network type camping, so as to ensure that the user communication will not be interrupted.

For example, a New Radio (NR) technique of 5G used by a blacklisted cell, but in the case where there is no 5G base station around, if there is a 4G/3G/2G base station, the terminal device 30 may reduce the network system to 4G/3G/2G, so that the terminal device 30 can perform communication. It will be appreciated that the priority of access by the terminal device 30 to the base stations is 5G > 4G > 3G > 2G, i.e. in case only 4G and 3G base stations are accessible, a base station of 4G will be preferentially accessed.

Alternatively, when the black list cell adopts 4*4 Multiple-Input Multiple-Out-put (MIMO) antenna technology, if there is no 4×4MIMO, but there is 3×2MIMO, or 2×2MIMO, or 1×1MIMO, the number of antennas for transmitting and receiving data may be reduced from 4×4MIMO to 3×3MIMO, or from 2×2MIMO, or even to 1×1MIMO.

In some embodiments, the database 20 also stores the optimization measure corresponding to the problem cell being a blacklisted cell, that is, when the terminal device approaches the blacklisted cell, the resident cell is determined by measuring whether the neighboring cell can be resident. The terminal device 30 can determine the cell which can reside directly according to the optimizing measure, and does not need to measure whether the adjacent cell can reside, thereby improving the efficiency of the terminal device for switching the residing cell.

S508: it is determined whether a neighboring cell is measured to be camping.

When the cell into which the terminal device 30 is about to enter is a low priority cell, the terminal device 30 does not preferentially select to camp on the cell. Therefore, at this time, the terminal device 30 will detect the signals of surrounding cells, detect whether there is a cell satisfying the camping condition, and when detecting that other cells around can camp, the terminal device 30 will execute step S509: and camping on other cells. If it is not detected that other cells around can camp on, the terminal device 30 will perform step S510: camping on a current low priority cell.

S509: and camping on other cells.

When the terminal device 30 detects that other cells around it can camp on, the terminal device 30 will camp on that cell.

S510: camping on a current low priority cell.

When the terminal device 30 detects that no other cells in the surrounding area can camp on, the terminal device 30 will also camp on the low priority cell.

In some embodiments, the database 20 also stores the corresponding optimization measures when the problem cell is a low priority cell, i.e. the previous terminal device determines the cell to camp on by measuring whether the neighboring cell can camp on when approaching the low priority cell. The terminal device 30 can directly camp on the cell according to the optimizing measure, and does not need to measure whether the adjacent cell can camp on, thereby improving the efficiency of the terminal device for switching the camping cell.

In some embodiments, for the terminal device 30 to enter the problem cell, measures for prohibiting the terminal device 30 from camping on the problem cell may be taken, or the user may be instructed to move the terminal device 30 to a region where the non-problem cell satisfies the camping condition, or other customized measures may be taken, which is not specifically limited in the present application. In some embodiments, the problem cell may also include other cells than the blacklisted cell and the low priority cell, i.e., cells with a lower number of subsystem resets than the low priority cell. For the problem cells which belong to neither the blacklisted cell nor the low priority cell, the terminal device 30 may perform processing in the non-problem cell, i.e. directly reside in the cell, may perform processing in the processing manner of the low priority cell, or may perform processing in the blacklisted cell.

S511: and judging whether the subsystem is reset or not.

After the terminal device 30 camps on the cell, it will also monitor whether the terminal device 30 has a subsystem reset, specifically, may determine whether the terminal device 30 has a subsystem reset according to the CHR dotting information of the terminal device 30. If the terminal device 30 has a subsystem reset, step S512 is performed: the currently camping cell is reported to the database 20. If the terminal device 30 does not generate a subsystem reset, the terminal device will record the results of determining whether to camp on the problem cell, determining the cell to camp on in the neighboring cell, and the like as an optimization measure, and execute step S513: reporting the optimization measures to the database 20.

S512: the currently camping cell is reported to the database 20.

If the terminal device 30 has a subsystem reset, the terminal device 30 reports the location or cell ID of the acquired camping cell to the database 20, and the database 20 records the subsystem reset.

S513: reporting the optimization measures to the database 20.

When the terminal device 30 does not generate the subsystem reset in the period of network residence, the terminal device 30 can consider that the cell where the terminal device 30 selects to reside can reside, the terminal device 30 can record the result of selecting to reside as an optimizing measure, and report the optimizing measure and the type of the cell to be approached to the database 20, so that other terminal devices can directly determine the cell to reside according to the optimizing measure when approaching the cell.

It should be appreciated that the occurrence of a subsystem reset by the terminal device 30 will most occur when a cell is camping, but in some embodiments the terminal device 30 may also monitor periodically or in real time after camping whether a subsystem reset has occurred by the terminal device. As soon as the terminal device 30 has undergone a subsystem reset, the terminal device 30 will perform step S512: the currently camping cell is reported to the database 20.

In summary, the terminal device can acquire the information of the problem cell frequently subjected to subsystem reset from the database, and when the terminal device approaches the problem cell, it is determined in advance whether to camp on the problem cell, and if the problem cell cannot camp on, it is determined that the cell to camp on is to be determined in the neighboring cell. After the terminal equipment enters the problem cell, subsystem reset is avoided, so that the terminal equipment service is prevented from being temporarily closed, and the user experience is improved. And the terminal equipment can upload the optimization measures to the database, so that other terminal equipment can directly optimize according to the optimization measures, the cell type is not required to be judged according to the number of times of resetting the cell subsystem, and the optimization strategy is determined, so that the judgment time before the terminal equipment resides in the network is saved, and the equipment cost is saved.

Another communication method provided by the embodiment of the present application is described in detail below with reference to fig. 6.

S601: cell information is acquired.

S602: real-time location information is obtained.

The terminal device 30 may periodically acquire the location information of the terminal device 30, for example, the location information of the terminal device 30 is acquired every minute by GPS. The terminal device 30 may also determine the position and the movement direction of the terminal device 30 according to the information such as the signal strength of the neighboring cell detected by the terminal device 30, and when the signal strength of the base station detected by the terminal device 30 in a certain cell increases gradually, it may be determined that the terminal device 30 is approaching the cell.

In some embodiments, the terminal device 30 may both obtain the terminal device 30 location information and detect the terminal device 30 vicinity signal strength, e.g., in case of failure to obtain the terminal device 30 location information, determine the location and movement direction of the terminal device 30 by detecting the vicinity signal strength in the vicinity of the terminal device 30. It should be understood that the manner in which the terminal device 30 obtains the real-time position is not particularly limited by the present application.

S603: and judging whether to move to the problem cell.

When the terminal device 30 is moving to the base station of the cell conforming to the camping condition, the terminal device 30 also determines whether the cell is a problem cell, and when it is determined that the terminal device 30 is moving to the problem cell, step S604 is performed: when it is determined that the cell to be camped on is not a problem cell according to the optimization measure, the terminal device 30 performs step S605: and judging whether the subsystem is reset or not.

S604: the cell to camp on is determined according to the optimization measure.

The terminal device 30 will determine whether the problem cell is in particular a blacklisted cell or a low priority cell based on the cell information obtained from the database 20. When the problem cell is a blacklisted cell, if the terminal device 30 detects other cells satisfying the camping condition, the terminal device 30 will not camp on the cell. If the problem cell is a low priority cell, the terminal device 30 will camp on other cells if the terminal device 30 detects other cells satisfying the camping condition, and if the terminal device 30 does not detect other cells satisfying the camping condition, the terminal device 30 will camp on the low priority cell. The specific execution of the optimization measures will be described in detail later.

In some embodiments, at step S601: when the location of the problem cell and the optimization measure corresponding to the problem cell are obtained together, when it is determined in step S603 that the terminal device 30 is about to enter the problem cell, the type of the problem cell and the cell suggested to reside in the residence optimization measure can be determined directly according to the optimization measure corresponding to the problem cell.

S605: and judging whether the subsystem is reset or not.

When the cell that the terminal device 30 approaches is not a problem cell, the terminal device 30 may normally camp on the approaching cell according to the movement direction, and meanwhile, the terminal device 30 will monitor whether the terminal device 30 generates the subsystem reset, specifically, may determine whether the terminal device 30 generates the subsystem reset according to the CHR dotting information of the terminal device 30. If the terminal device 30 has a subsystem reset, step S606 is performed: the currently camping cell is reported to the database 20. If the terminal device 30 does not generate the subsystem reset, the step S602 is continued to be executed: the real-time location information is acquired, whether the terminal device 30 is about to enter the problem cell is continuously judged, if the terminal device 30 is about to enter the problem cell, optimization measures are acquired, and if the terminal device 30 is not about to enter the problem cell, whether subsystem reset of the terminal device 30 occurs is continuously judged.

It should be appreciated that the case where the terminal device 30 does not have a subsystem reset occurs mostly when it has just camped on a cell, but in some embodiments, the terminal device 30 may also monitor whether the terminal device has a subsystem reset periodically or in real time after the camping. As soon as the terminal device 30 has undergone a subsystem reset, the terminal device 30 will execute step S606: the currently camping cell is reported to the database 20.

S606: the currently camping cell is reported to the database 20.

After the subsystem is reset, the terminal device 30 acquires the position or the cell ID of the cell where the current terminal device 30 resides, reports the acquired position or the cell ID of the cell where the current terminal device 30 resides to the database 20, and the database 20 records the subsystem reset. The location of the camping cell or the cell ID may be queried by means of message registration information query or GPS positioning, etc.

In summary, the terminal device can obtain the information of the problem cell that is subjected to subsystem reset from the database, when the terminal device approaches the problem cell, it is determined in advance whether to camp on the problem cell, and if the problem cell cannot camp on, it is determined that the cell to camp on is to be determined in the neighboring cell. After the terminal equipment enters the problem cell, subsystem reset is avoided, so that the terminal equipment service is prevented from being temporarily closed, and the user experience is improved.

Step S604 in the above communication method is described below with reference to fig. 7: the determination of the cell to camp on is described in detail in terms of the optimisation procedure.

S701: whether the problem cell is a blacklisted cell.

The database 20 stores the number of times that the subsystem reset occurs to the cell as the cell information, the terminal device 30 can determine whether the problem cell is a blacklisted cell according to the number of times that the subsystem reset occurs, or the database 20 directly stores the type of the problem cell, and the terminal device 30 can directly determine whether the problem cell is a blacklisted cell according to the type of the problem cell. Reference is specifically made to step S3 in fig. 4 described above. When the problem cell is a blacklisted cell, the terminal device 30 performs step S702: and determining the blacklist cell silence duration. If the problem cell is not a blacklisted cell, step S706 is performed: whether the problem cell is a low priority cell.

S702: and determining the blacklist cell silence duration.

The terminal device 30 records the number of times of approaching the blacklisted cells, the number of times is K, K defaults to 0, the silence duration may be k×x minutes, and X is a positive number. When the terminal device 30 enters the blacklist cell for the first time, the K value is increased by 1, and the terminal device 30 performs step S703: and judging whether the neighboring cell can be resided or not, and resided in the cell according to the judging result. After X minutes, if the terminal device 30 remains in the blacklisted cell, the K value is increased by 1 again, and the terminal device 30 will execute step S703 again: it is determined whether a neighboring cell is measured to be camping. 2*X minutes, the terminal device 30 will repeat the above steps again, and so on. Where X may be customizable, and X may take 10 minutes, for example. Reference is specifically made to the above step S505, and details thereof are not repeated here.

S703: it is determined whether a neighboring cell is measured to be camping.

When the cell into which the terminal device 30 is about to enter is a blacklisted cell, the terminal device 30 does not select to actively camp on the blacklisted cell. Thus, the terminal device 30 will detect the signals of surrounding cells, detecting whether there is a cell satisfying the camping condition. When detecting that other cells around can camp on, the terminal device 30 will perform step S705: and camping on other cells. If it is not detected that other cells around can camp on, the terminal device 30 will execute step S704: network system is reduced and other cells are resided.

S704: reduce network system and reside the problem cell.

When the terminal device 30 does not detect that there are cells surrounding the cell which meet the camping condition, the terminal device 30 will reduce other cells which can camp around the network type camping, so as to ensure that the user communication will not be interrupted. Reference may be made to step S507 as described above: and reducing network type resident other cells.

After the terminal device 30 reduces the network system and camps on the problem cell, the terminal device 30 will also monitor whether the subsystem reset occurs, i.e. execute step S710: and judging whether the subsystem is reset or not.

S705: and camping on other cells.

When the terminal device 30 detects that other cells around it can camp on, the terminal device 30 will camp on that cell. It should be understood that after camping on the cell, the terminal device 30 will also monitor whether a subsystem reset occurs or not by the terminal device 30, i.e. execute step S710: and judging whether the subsystem is reset or not.

In some embodiments, the database 20 also stores the optimization measure corresponding to the problem cell being the blacklisted cell, that is, the cell that can be determined to be resided after the terminal device approaches the blacklisted cell by measuring whether the neighboring cell can be resided. The terminal device 30 can directly camp on the cell according to the optimizing measure, and does not need to measure whether the adjacent cell can camp on, thereby improving the efficiency of the terminal device for switching the camping cell.

S706: whether the problem cell is a low priority cell.

Depending on the number of times of the subsystem reset or the type of the problem cell stored in the database 20, it can be determined whether the problem cell is a low priority cell, and if the problem cell is a low priority cell, step S707 is performed: it is determined whether a neighboring cell is measured to be camping. When the problem cell is not a low priority cell, it is indicated that the current problem cell is neither a blacklisted cell nor a low priority cell, and the terminal device may perform an operation corresponding to the blacklisted cell on the cell, that is, perform step S702: and determining the blacklist cell silence duration.

In some embodiments, for the problem cell that belongs to neither the blacklisted cell nor the low priority cell, the terminal device 30 may perform processing in a non-problem cell, i.e. directly reside in the cell, or may perform processing in a processing manner of the low priority cell, i.e. perform step S707: whether the neighboring cell is measured to be resident or other strategies are executed is judged, and the application is not particularly limited.

S707: it is determined whether a neighboring cell is measured to be camping.

When the cell into which the terminal device 30 is about to enter is a low priority cell, the terminal device 30 does not preferentially select to camp on the cell. Therefore, at this time, the terminal device 30 will detect the signals of the surrounding cells, detect whether there is a cell satisfying the camping condition, and when detecting that other cells around can camp, the terminal device 30 will execute step S708: and camping on other cells. If it is not detected that other cells around can camp on, the terminal device 30 will execute step S709: camping on a current low priority cell.

S708: and camping on other cells.

When the terminal device 30 detects that other cells around it can camp on, the terminal device 30 will camp on that cell. Reference is specifically made to the aforementioned step S509: the other cells are camped on and are not described in detail herein.

After the terminal device 30 camps on the other cell, the terminal device 30 will also monitor whether the subsystem reset occurs, i.e. execute step S710: and judging whether the subsystem is reset or not.

S709: camping on a current low priority cell.

When the terminal device 30 detects that no other cells in the surrounding area can camp on, the terminal device 30 will also camp on the low priority cell. Likewise, after camping on the low priority cell, the terminal device 30 will also monitor in real time whether the subsystem reset has occurred, i.e. execute step S710: and judging whether the subsystem is reset or not.

In some embodiments, for the terminal device 30 to enter the problem cell, measures for prohibiting the terminal device 30 from camping on the problem cell may be taken, or the user may be instructed to move the terminal device 30 to a region where the non-problem cell satisfies the camping condition, or other customized measures may be taken, which is not specifically limited in the present application.

S710: and judging whether the subsystem is reset or not.

The terminal device 30 may specifically determine whether the subsystem reset occurs in the terminal device 30 according to the CHR dotting information of the terminal device 30. If the terminal device 30 does not perform the subsystem reset during the cell camping, step S711 is executed: reporting the optimization measures and optimization results to the database 20. If the terminal device 30 has a subsystem reset during cell camping, step S712 is performed: the currently camping cell is reported to the database 20.

S711: reporting the optimization measures to the database 20.

When the terminal device 30 does not generate the subsystem reset in the period of network residence, the terminal device 30 can consider that the cell where the terminal device 30 selects to reside can reside, the terminal device 30 can record the result of selecting to reside as an optimizing measure, and report the optimizing measure and the type of the cell to be approached to the database 20, so that other terminal devices can directly reside in the cell according to the optimizing measure when approaching the cell. And, since the subsystem reset does not occur in the terminal device 30, the optimization result corresponding to the optimization measure is that the optimization is successful.

It should be understood that if the terminal device 30 successfully camps on the cell, after a period of time, if a subsystem reset occurs, step S720 is also performed to report the currently camping cell to the database 20.

S712: reporting the cell in which it will currently reside to the database 20.

In some embodiments, the terminal device 30 will also upload the optimization measures to the database 20, wherein, since the terminal device 30 has undergone a subsystem reset based on the optimization measures, the optimization result corresponding to the optimization measures is an optimization failure.

In summary, the terminal device can acquire the problem cell information requiring the subsystem reset by the communication method provided by the application, before the terminal device enters the problem cell, whether the problem cell resides or not can be determined according to the cell information, and if the problem cell cannot reside, the cell to reside is determined in the adjacent cell. After the terminal equipment enters the problem cell, subsystem reset is performed, so that the problem that the terminal equipment service is temporarily closed is avoided, and the user experience is improved. And the terminal equipment can upload the optimization measures to the database, so that other terminal equipment can directly optimize according to the optimization measures, the cell type is not required to be judged according to the number of times of resetting the cell subsystem, and the optimization strategy is determined, so that the judgment time before the terminal equipment resides in the network is saved, and the equipment cost is saved.
