Technical field

The present application belongs to the field of communication technology, and specifically relates to a wireless access processing method, information transmission method, device and equipment.

Background technique

The random access process is an important process in the mobile communication system to achieve uplink synchronization between the terminal and the base station. Due to the randomness of users and the complexity of the wireless environment, the initiation of this access and the resources used are also random, which makes it possible for the terminal to establish a communication connection with the network. However, random access failure will cause the terminal to be unable to access the network, thus affecting the normal communication of the terminal.

There are various reasons for random access failure. One of the cases is that the cell random access parameters can only support the successful random access of terminals that are closer to the base station. However, if the terminals that are far away from the base station choose to use the random access parameter due to the strong cell signal strength, When camping in the cell, random access failures will occur repeatedly, resulting in the terminal not only being unable to access the cell corresponding to the base station, but also being unable to access other cells, resulting in the inability to use cellular communication services for a long time.

Detailed ways

The technical solutions in the embodiments of the present application will be clearly described below with reference to the accompanying drawings in the embodiments of the present application. Obviously, the described embodiments are part of the embodiments of the present application, but not all of the embodiments. Based on the embodiments in this application, all other embodiments obtained by those of ordinary skill in the art fall within the scope of protection of this application.

The terms "first", "second", etc. in the description and claims of this application are used to distinguish Similar objects, rather than describing a specific order or sequence. It is to be understood that the figures so used are interchangeable under appropriate circumstances so that the embodiments of the present application can be practiced in orders other than those illustrated or described herein, and that "first,""second," etc. are distinguished Objects are usually of one type, and the number of objects is not limited. For example, the first object can be one or multiple. In addition, "and/or" in the description and claims indicates at least one of the connected objects, and the character "/" generally indicates that the related objects are in an "or" relationship.

The terminal's cell search in the 5th Generation Mobile Communication Technology (5G) New Radio (NR) network is divided into two types: one is the initial cell search, and the other is based on stored information neighborhood search.

When the terminal selects the Public Land Mobile Network (PLMN), it starts the cell search process. If the terminal stored information contains the cell information of the PLMN, then "cell search based on stored information" is started. If a "suitable cell" is not found during the cell search based on stored information, an "initial cell search" is started.

If the terminal stored information does not contain the cell information of the PLMN, the cell starts "initial cell search".

For these two types of cell searches, if the terminal finds a "suitable cell", the terminal camps on this "suitable cell".

Among them, "suitable community" is a community that meets the following conditions:

The cell belongs to a selected PLMN, a registered PLMN, or a PLMN in the list of equivalent PLMNs;

Meet the S criterion for cell selection;

According to the latest information of the terminal's Non-Access Stratum (NAS), the cell is not set to "forbidden cell selection and prohibited cell reselection";

According to the latest information from the terminal NAS, the tracking area code (TAC) of the cell is not in the "Forbidden Tracking Areas" list.

The "suitable cell" here does not guarantee that the terminal can successfully access randomly. If the terminal repeatedly fails to randomly access the cell, the terminal cannot use the cellular communication function.

The NR random access process is divided into contention-based random access (Contention-Based Random Access, CBRA) and non-contention random access (Contention-Free Random Access, CFRA). in Both random access processes involve Msg1 (ie, Random Access Preamble) and Msg2 (ie, Random Access Response). If the content of Msg2 received after the terminal sends Msg1 does not meet expectations, it will also cause the terminal to fail to access randomly. The specific reasons are analyzed as follows:

The relationship between the cyclic shift value Ncs in the random access parameters in the NR system and the cell coverage radius is: when other parameters remain unchanged, the cell coverage radius is proportional to Ncs. That is, the larger the Ncs is, the larger the cell radius that can be supported.

When the terminal is far away from the base station, the terminal sends the random access preamble of Msg1, which is easily mapped to an incorrect cyclic shift value when demodulated on the base station side, causing the terminal to receive the Medium Access Control (Medium Access Control) in Msg2. , MAC) information’s Random Access Preamble Identifier (RAPID) field does not match expectations, causing the terminal’s random access to fail. Moreover, since the signal strength of the cell does not match the random access related parameters configured by the base station, the terminal will continue to repeat the above random access process in the cell, resulting in the terminal not only being unable to access the cell corresponding to the base station, but also being unable to access. Other cells, resulting in the inability to use cellular communication services for a long time.

In order to solve the above problems, embodiments of the present application provide a wireless access processing method, an information transmission method, an apparatus and an electronic device. The method of the embodiment of the present application involves the interaction between the terminal and the server. For ease of understanding, the following Embodiment 1 is used to describe the processing process of the terminal after random access failure, starting from the overall interaction process. See Figure 1, the specific steps are as follows:

S101: When a random access failure occurs in the first cell, the first terminal sends at least one piece of first information to the server.

Wherein, the first terminal is a terminal in a first group of terminals, the first group of terminals includes N first terminals, and the N first terminals all have random access failures in the first cell.

The first information is used to indicate information related to random access failure of the first terminal.

It should be noted that random access failure means that the number of preambles sent by the first terminal has reached n times, but the first terminal still fails to receive a matching random access response, or the contention resolution has not been completed. Among them, n is a positive integer greater than 1, and n is configured by the network side device. The network side device here can be a base station.

The random access failure of the first terminal in the first cell includes but is not limited to: the first terminal fails in the first cell. n1 consecutive random access failures occur in the cell, n1 is a positive integer greater than 1; the number of random access failures of the first terminal in the first cell exceeds the preset number of times within a period of time, and the first terminal has random access failures in the first cell. and random access success and random access failure appear alternately in the random access results.

Optionally, the first information includes at least one of the following information:

Information about the target cell. The target cell includes at least one of the first cell, the second cell, and the third cell. The second cell is a neighboring cell of the first cell, and the third cell is the one that the first terminal has successfully accessed for the last N1 times. Cell, N1≥1, and N1 is a positive integer;

first random access information;

Time information when random access failure occurs;

The geographical location information of the first terminal when a random access failure occurs.

Among them, the neighbor cell of the first cell, that is, the second cell, may be one or multiple cells, and is not limited here. The third cell may be one cell or multiple cells, and is not specifically limited here.

It should be noted that the purpose of the first terminal sending the information of the second cell and/or the information of the third cell to the server is to provide reference information to the server, that is, the server can instruct the second terminal in the second group of terminals to select the third cell. Camp on the second cell or the third cell instead of camping on the first cell.

Optionally, the information of the target cell includes at least one of the following information:

Public land mobile network identification PLMN ID;

Radio Access Technology (RAT) information;

Frequency information;

Physical Cell Identifier (PCI);

community identification;

signal strength;

Tracking area information;

Core Net information where it is located;

Radio Access Network (RAN) area information.

Optionally, the first random access information includes at least one of the following information:

Number of consecutive random access attempts;

Indicates the random access result of random access failure.

Here, the geographical location information of the first terminal when a random access failure occurs includes at least one of the following information: the longitude of the first terminal, the latitude of the first terminal, and the altitude of the first terminal.

S102: The server determines the second information and the first area corresponding to the random access failure based on the first information.

It should be understood that if a terminal located in the first area and has not attempted random access in the first cell attempts to access the first cell, the result will be a failure.

Information about the first community;

Cell restriction time information corresponding to the second terminal;

First area.

S103. The server sends the second information to the second group of terminals in the first area. The second group of terminals includes M second terminals, M≥1, and M is a positive integer.

It should be noted that the location of the first terminal when the random access failure occurs is in the first area. At this time, the first group of terminals belongs to the second group of terminals, that is, the first group of terminals is a child of the second group of terminals. set.

Here, after the second terminal receives the second information, it can know, through the second information, the information of the cell in which the terminal in the first area where it is located has failed random access, that is, the information of the first cell.

If the second information includes cell restriction time information corresponding to the second terminal, the purpose is to instruct the second terminal to perform the restriction process on the first cell. Optionally, the cell restriction time information corresponding to the second terminal includes a cell restriction duration corresponding to the second terminal, or a cell restriction end time corresponding to the second terminal.

It should be understood that the cell restriction period may start counting from the moment when the second terminal receives the second information and continue to limit the preset period. The cell restriction end time corresponding to the second terminal is a time in the future. For example, if the second information is sent by the server at 10 am, the cell restriction end time corresponding to the second terminal is 6 pm.

It should be noted that the cell restriction time information corresponding to different second terminals may be the same or different, and is not specifically limited here.

If the second information includes the first area, the purpose is to enable the second terminal to determine whether its current location is still within the first area after receiving the second information, and execute if it is within the first area. Step S104; If it is not within the first area, ignore the second information and do not perform any processing. The purpose of this is to enable the terminal that is still in the first area when the server receives the first information, but is no longer in the first area when receiving the second information, to avoid restricting the first cell and be able to save resources.

S104: The second terminal restricts camping or access in the first cell based on the second information.

Here, the second terminal refers to a terminal located in the first area.

In an optional implementation, in step S104, restricting camping or access on the first cell may include:

It is prohibited to stay in the first community;

Random access in the first cell is prohibited;

The number of random access attempts in the first cell shall not exceed N2 times, N2≥1, and N2 is a positive integer;

Lower the priority associated with the first cell.

It should be noted that the wireless access processing method in the embodiment of the present application uses the information after a small number of terminals (that is, the first group of terminals) fail to randomly access a cell, and uses the server to help within an area (the first area). ) within the area (i.e., the second group of terminals) avoid the cell in advance and do not camp or conduct random access in the cell as little as possible, thereby saving most terminals in the area from repeatedly trying random access in the cell. The time cost is such that the second terminal attempts to access another cell with a stronger signal, thereby ensuring the cellular communication quality of the terminal in the area.

Based on the above, further, the method may also include:

The third group of terminals in the second group of terminals attempts random access to the first cell after the restriction on the first cell reaches the preset duration or reaches the specified time and the restrictions on camping or access to the first cell are lifted. , get the random access result.

If the random access is successful and the number of consecutive attempts is less than or equal to the preset number, the second terminal records the third information and sends the third information to the server.

Here, the third information is used to indicate information related to the success of random access of the second terminal.

The server determines the fourth information and the second area based on the third information sent by the plurality of second terminals, and sends the fourth information to a fourth group of terminals in the second area.

After that, the terminals in the fourth group of terminals receive the fourth information sent by the server; and according to the fourth information to release the restriction process of camping or accessing on the first cell.

After some terminals in the first area lift the restrictions on camping or accessing on the first cell and successfully try to access the first cell, it means that the random access function of the first cell returns to normal. After the above processing, That is, all terminals in the area (i.e., the second area) corresponding to the random access function of the first cell are restored to normal and the restrictions on camping or access on the first cell are lifted, and the first cell can be used as the camper as soon as possible. Or randomly access candidate cells, providing more possibilities for better cellular communication quality.

The method provided by the embodiments of the present application will be described in detail below from the perspective of a single-sided entity and in conjunction with the accompanying drawings through specific embodiments and application scenarios.

As shown in Figure 2, it is a schematic flow chart of a wireless access method provided by an embodiment of the present application. This method is executed by the second terminal. The following is a detailed description of the implementation process of this method based on this figure.

Step 201: The second terminal receives the second information sent by the server, where the second terminal is a terminal in the second group of terminals in the first area, and the first area and the second information are determined based on the first information; first The information is used to indicate information related to the random access failure of the first terminal, and the first terminal is a terminal that has a random access failure in the first cell.

Information about the first community;

Cell restriction time information corresponding to the second terminal;

First area.

It should be noted that after the second terminal receives the second information, it can know, through the second information, the information of the cell in which the terminal in the first area where it is located has a random access failure, that is, the information of the first cell.

If the second information includes the first area, the purpose is to enable the second terminal to determine whether its current location is still within the first area after receiving the second information. If it is within the first area, perform step 202; if If it is not within the first area, the second information is ignored and no processing is performed. The purpose of this is to enable the terminal that is still in the first area when the server receives the first information, but is no longer in the first area when it receives the second information, to avoid restricting the first cell and be able to save resources.

Step 202: The second terminal restricts camping or access on the first cell based on the second information.

In an optional implementation, in step 202, restricting camping or access on the first cell includes:

It is prohibited to stay in the first community;

Random access in the first cell is prohibited;

Lower the priority associated with the first cell.

Here, prohibiting camping in the first cell means prohibiting cell selection and/or cell reselection in the first cell.

Lowering the priority related to the first cell specifically refers to lowering the priority related to the first cell when the second terminal performs at least one operation of cell selection, cell reselection, and random access.

In the wireless access processing method of the embodiment of the present application, the second terminal in the second group of terminals uses the server's processed indication of the information related to the random access failure of the first terminal, that is, the second information, to perform the processing in the first cell. By restricting the parking or access in the first cell, the first cell can be avoided in advance, and the parking or random access in the cell can be avoided or as little as possible, thereby reducing the repeated random access of the second terminal in the first area. The time cost of the attempt is to make the second terminal try to access another cell with a stronger signal, thereby ensuring the cellular communication quality of the terminal in the area.

Information about the target cell. The target cell includes at least one of the first cell, the second cell and the third cell. The second cell is a neighboring cell of the first cell, and the third cell is the first terminal's recent N1 successes. Accessed cell, N1≥1, and N1 is a positive integer;

first random access information;

Time information when random access failure occurs;

Here, the meaning of each of the above information can be explained in detail in the embodiment shown in Figure 1, and will not be described again here.

It should be noted that if the second information includes cell restriction time information corresponding to the second terminal, then the second terminal can release the restriction on the first cell after the restriction on the first cell reaches the preset duration or reaches the specified time. limit. Or if the second information does not include the cell restriction time information corresponding to the second terminal, but the second terminal can also release the restriction on the first cell after the restriction on the first cell reaches the preset duration or reaches the specified time according to the predetermined agreement. limits.

In an optional implementation manner, the method of the embodiment of the present application may also include:

a1: The second terminal sends the third information to the server when it determines that the first condition is met.

The first condition includes that the second terminal succeeds in random access in the first cell after lifting restrictions on camping or access in the first cell; the third information is used to determine the second area corresponding to the successful random access. and fourth information.

Optionally, the third information includes at least one of the following information:

Information about the first community;

second random access information;

Time information when random access succeeds;

The geographical location information of the second terminal when random access succeeds.

Here, the second random access information includes at least one of the following information:

Number of consecutive random access attempts;

Random access result indicating successful random access.

Here, the geographical location information when the random access is successfully sent by the second terminal includes at least one of the following: the longitude of the first terminal, the latitude of the second terminal, and the altitude of the second terminal.

It should be noted that the above third information is used to enable the server to determine the second area and fourth information corresponding to successful random access based on the third information, and send the fourth information to the fourth group of terminals in the second area.

It should be understood that for a terminal that is in the second area and has not released the restriction process on the first cell, if it attempts to access the first cell after the restriction process on the first cell is released, the result will be a successful access.

Optionally, the fourth information includes at least one of the following information:

Information about the first community;

Second area.

Here, if the fourth information includes information about the first cell, the purpose is to indicate to the terminals in the fourth group of terminals that the first cell is a cell that can successfully access, and the first cell can be used as a camp or random access. candidate area.

If the fourth information includes the second area, the purpose is to enable the terminals in the fourth group of terminals to determine whether their current location is still within the second area after receiving the fourth information. If they are within the second area, then The restriction processing on the first cell is immediately released, and the first cell is used as a candidate cell for camping or random access, without considering whether the cell restriction time has reached or arrived; if it is not within the second area, the fourth information is ignored.

The purpose of this is to enable the terminal that is still in the second area when receiving the third information and the terminal that is still in the second area when receiving the fourth information to immediately lift the restrictions on the first cell, thereby Allow terminals in the second area to use cellular communication services through the first cell as soon as possible.

In an optional implementation, if the second terminal is a terminal in a fourth group of terminals, the fourth group of terminals is a subset of the second group of terminals; the method in the embodiment of the present application further includes:

b1: Receive the fourth information sent by the server.

b2: According to the fourth information, release the restriction process of camping or access on the first cell.

Here, the second terminal can release the restriction process of camping or accessing on the first cell according to the fourth information, so as to enable the second terminal to use the cellular communication service as soon as possible.

It should be noted that, optionally, the process of lifting restrictions on camping or accessing the first cell includes at least one of the following:

Allowed to reside in the first community;

Allow random access in the first cell;

Increase the priority associated with the first cell.

Here, allowing to camp on the first cell means allowing cell selection and/or cell reselection in the first cell.

Increasing the priority related to the first cell specifically refers to increasing the priority related to the first cell when the second terminal performs at least one operation of cell selection, cell reselection, and random access.

It should be explained that the priority related to the first cell includes at least one of the following:

The priority of the first cell;

The priority of the frequency point where the first cell is located;

The priority of the radio access technology RAT where the first cell is located;

The priority of the public land mobile network PLMN where the first cell is located.

As shown in Figure 3, it is a schematic flow chart of the information transmission method provided by the embodiment of the present application. This method is executed by the server. The following figure explains the implementation process of this method in detail.

Step 301: The server obtains the first information sent by the first group of terminals, where the first group of terminals includes N first terminals, the first terminal is a terminal that fails random access in the first cell, and the first information is used to indicate Information related to the random access failure of the first terminal, N≥1, and N is a positive integer.

Specifically, the server obtains the first information sent by each first terminal in the first group of terminals.

first random access information;

Time information when random access failure occurs;

Step 302: The server determines the second information and the first area corresponding to the random access failure based on the first information.

Information about the first community;

Cell restriction time information corresponding to the second terminal;

First area.

Here, the server may determine the location of the first terminal when the random access failure occurs based on the first information. The location information is used to estimate the first area corresponding to the random access failure.

The cell restriction time information corresponding to the second terminal refers to the cell restriction time information corresponding to the second terminal and the restriction object is the first cell.

It should be noted that after receiving the first information sent by the first group of terminals, the server determines the first area corresponding to the random access failure, and the terminals in the first area (terminals in the second group of terminals below) If you try to access the first cell, the result will be failure. In order to save the time cost of most terminals in the area repeatedly trying random access in the cell and ensure the cellular communication quality of the terminals in the area, the server generates second information to indicate the second group of terminal pairs currently in the first area. Camping or random access in the first cell is restricted.

Step 303: The server sends the second information to the second group of terminals in the first area. The second group of terminals includes M second terminals, M≥1, and M is a positive integer.

Here, the server sends second information to the second group of terminals in the first area, the purpose of which is to instruct the second group of terminals currently in the first area to respond to the camping or random access in the first cell based on the second information. Entry is restricted.

It should be noted that the server in the embodiment of the present application may be one or multiple servers. That is to say, the above processing steps may be completed by one server or multiple servers, and are not specifically limited here. Among them, when it is completed by multiple servers, different processing tasks are assigned to different servers and completed through division of labor and cooperation between servers. For example, one server is responsible for collecting the first information, another server is responsible for making calculation decisions on the collected first information, and obtaining the second information and the first area corresponding to the random access failure; another server is responsible for reporting the first information to the first area. The second group of terminals in the area sends the second information.

In the information transmission method of the embodiment of the present application, the server uses the first information sent by the first group of terminals after a random access failure occurs in the first cell, determines the second information and the first area corresponding to the random access failure, and sends the information to the first area. The second group of terminals in an area generates second information to instruct the second group of terminals currently in the first area to restrict camping or random access in the first cell based on the second information, thereby helping the second group of terminals. Most terminals in an area, that is, the second group of terminals, avoid the cell in advance and do not camp or randomly access the first cell as much as possible, thereby saving the second group of terminals in the first area from repeatedly visiting the first cell. The time cost of the first cell trying random access ensures the cellular communication quality of the terminal in the first area.

It should be noted that the server not only receives information sent by some terminals after random access failure in the first cell, but also receives information sent by other terminals after random access failure in other cells. Therefore, in order to distinguish random access in different cells, For terminals that have failed to access, in order to facilitate subsequent information processing, the server needs to group the terminals according to the cells where the random access failed.

In an optional implementation, in method step 301 of the embodiment of the present application, the server obtains the first information sent by the first group of terminals, including:

Step 3011: The server receives the fifth information sent by T third terminals, where the third terminal is a terminal that has failed random access in the cell where it resides, and the fifth information is used to indicate random access with the third terminal. Failure-related information, T≥N≥1, and T is a positive integer.

Here, the third terminal generally refers to a terminal that fails in random access in the cell where it resides. The cell where the third terminal is camped may be the first cell or another cell.

Step 3012: Based on the fifth information, the server classifies the third terminal that meets the second condition as the first terminal and divides it into the first group of terminals.

Wherein, the second condition includes at least one of the following:

The cells they reside in are the same and both are the first cell;

The difference between the time when the random access failure of the third terminal occurs in the first cell and the first time value is within the first preset range. The first time value is the time value in the middle of the first sequence, or the first time value of the first set. The average time value, the first sequence is formed by the times when T third terminals fail to access randomly in the first cell in chronological order, and the first set includes the times when T third terminals fail to access randomly in the first cell. time;

The geographical location of the third terminal differs from the first geographical location within a second preset range. The first geographical location is the geographical location in the middle of the second number sequence, or the average geographical location of the second set. The second number sequence consists of T The geographical locations of the third terminals are arranged in order of distance from the first cell, and the second set includes the geographical locations of T third terminals.

Here, if the second condition includes that the difference between the time when the random access failure of the third terminal occurs in the first cell and the first time value is within the first preset range, it means that the random access failure will occur in the first cell. Multiple third terminals that are close in time are used as the first terminals and are divided into the first group of terminals, and third terminals that are far apart in time are excluded. In this way, the server subsequently uses the first information sent by the first group of terminals, The determined second information and first area are more accurate and timely.

If the second condition includes that the geographical location of the third terminal is different from the first geographical location within the second preset range, it means that multiple third terminals that are not far apart and relatively close in geographical location are used as the first terminal, and the To the first group of terminals, third terminals that are geographically far apart are excluded. In this way, the server subsequently determines the second information and the first area more accurately based on the first information sent by the first group of terminals.

Step 3013: The server obtains the fifth information sent by the third terminal that meets the second condition, and uses it as the first information sent by the first group of terminals.

It should be noted that different terminals have different communication attributes, and the corresponding matching base stations that can provide services for them are also different. If the base station corresponding to the first cell supports 5G technology, but the terminal is a terminal that does not support 5G technology, or the PLMN to which the base station corresponding to the first cell belongs is different from the PLMN registered by the terminal, etc., these situations will cause some terminals to fail due to their own communication. attribute and cannot access the first cell. There may be terminals in the first area that cannot access the first cell due to their own communication attributes. In order to save network resources, the server needs to divide the terminals in the first area that match the first information based on the first information. One group only needs to send the second information to the terminals of this group.

Therefore, in an optional implementation manner, before method step 303, the method of the embodiment of the present application may further include:

c1, the server obtains P fourth terminals in the first area, P≥M, and P is a positive integer.

c2. Based on the first information, the server classifies the fourth terminal that meets the third condition as the second terminal and divides it into the second group of terminals. The third condition is that the communication attributes of the fourth terminal match the first information, and the communication Attributes include communication capabilities supported by the terminal and/or communication status of the terminal.

Among them, the communication capabilities supported by the terminal refer to the RAT corresponding to the random access failure. The terminal status of the terminal refers to at least one of cell information, frequency point information and PLMN where the terminal is camped or accessed.

It should be noted that, after the server sends the second information to the second group of terminals in the first area, the second group of terminals receives the second information sent by the server, and based on the second information, determines whether to camp in the first cell or Access is restricted.

It should be understood that the restriction process on the first cell is not permanent. The restriction can be lifted when the restriction time reaches the preset duration or reaches the preset end time (ie, a certain moment in the future). After that, the terminal can try to access the third cell again. A small area. Here, after the second terminal releases the restriction process on camping or accessing the first cell, and when the random access to the first cell is successful, the third information will be sent to the server, It is used to enable the server to determine the second area and fourth information corresponding to successful random access based on the third information, and send the fourth information to the fourth group of terminals in the second area.

Therefore, in an optional implementation manner, the method of the embodiment of the present application further includes:

d1, the server obtains the third information sent by the third group of terminals. The third group of terminals is a subset of the second group of terminals. The second terminal in the third group of terminals meets the first condition. The first condition includes the second terminal releasing the pair. After the camping or access restriction of the first cell is processed, the random access in the first cell is successful.

Information about the first community;

second random access information;

Time information when random access succeeds;

The geographical location information of the second terminal when the random access is successful and the random access is successful.

Here, the meaning of each of the above information can be explained in detail in the embodiment shown in Figure 2, and will not be described again here.

d2. Based on the third information, determine the fourth information and the second area corresponding to the successful random access.

Here, the server may estimate the second area corresponding to the successful random access based on the geographical location information of the second terminal when the random access is successful in the third information.

Information about the first community;

Second area.

The purpose of this is to enable the server to immediately lift restrictions on the first cell when the server is still in the second area when receiving the third information, and the terminal is still in the second area when receiving the fourth information. management, so that terminals in the second area can use cellular communication services through the first cell as soon as possible.

d3: Send the fourth information to the fourth group of terminals in the second area, and the fourth group of terminals is a subset of the second group of terminals.

Here, the server sends the fourth information to the fourth terminal in the second area, the purpose of which is to enable the second terminal in the fourth group of terminals to release the restriction process of camping on or accessing the first cell based on the fourth information, to enable the fourth group of terminals to use the cellular communication service as soon as possible.

Optionally, the second terminal in the third group of terminals also satisfies a fourth condition, and the fourth condition includes at least one of the following:

The difference between the time when the second terminal succeeds in random access in the first cell and the second time value is within the third preset range, where the second time value is the time value in the middle of the third sequence, or the third time value. The average time value of the set, the third sequence is formed by all the second terminals in the third group of terminals arranged in chronological order when random access success occurs in the first cell, and the third set includes the third group of terminals The time when random access of all second terminals in the first cell is successful;

The geographical location of the second terminal differs from the second geographical location within the fourth preset range. The second geographical location is the geographical location located in the middle of the fourth numerical sequence, or the average geographical location of the fourth set. The fourth numerical sequence consists of the third The geographical locations of all the second terminals in the group of terminals are arranged in order of distance from the first cell, and the fourth set includes the geographical locations of all the second terminals in the third group of terminals.

In this implementation, the third group of terminals also needs to satisfy the fourth condition so that the server can subsequently determine the fourth information and the second area more accurately based on the third information sent by the third group of terminals.

As shown in Figure 4, it is a schematic flow chart of an information transmission method provided by an embodiment of the present application. This method is executed by the first terminal. The following is a detailed description of the implementation process of this method based on the figure.

Step 401: When a random access failure occurs in the first cell, the first terminal sends at least one first information to the server, where the first terminal is a terminal in the first group of terminals; where the first information is used to determine The second information and the first area corresponding to the random access failure.

Cell restriction time information corresponding to the second terminal;

First area.

Here, the first information is used to enable the server to determine the second information and the random access loss based on the first information. The first area corresponding to the failure is lost, and the second information is sent to the second group of terminals in the first area, and then the second group of terminals restricts camping or access to the first cell based on the second information.

Optionally, the first terminal communicates with the server through the Internet, a local area network, or the Internet of Things.
