Description

Technical Field

Background

The random access process is an important process for realizing uplink synchronization between a terminal and a base station in a mobile communication system. Since the randomness of the user and the complexity of the wireless environment determine the initiation of the access and the adopted resources are also random, it is possible for the terminal to establish a communication connection with the network. And the failure of random access can cause that the terminal can not access the network, thereby influencing the normal communication of the terminal.

The reasons for the random access failure are various, and in one case, the cell random access parameter can only support the successful random access of the terminal at a close distance, and if the terminal at a far distance from the base station selects to reside in the cell due to the strong signal strength of the cell, the random access failure will occur repeatedly, so that the terminal cannot access the cell corresponding to the base station and cannot access other cells, and the cellular communication service cannot be used for a long time.

Detailed Description

The technical solutions in the embodiments of the present application will be described clearly below with reference to the drawings in the embodiments of the present application, and it is obvious that the described embodiments are some, but not all, embodiments of the present application. All other embodiments that can be derived by one of ordinary skill in the art from the embodiments given herein are intended to be within the scope of the present disclosure.

The terms first, second and the like in the description and in the claims of the present application are used for distinguishing between similar elements and not necessarily for describing a particular sequential or chronological order. It will be appreciated that the data so used may be interchanged under appropriate circumstances such that embodiments of the application may be practiced in sequences other than those illustrated or described herein, and that the terms "first," "second," and the like are generally used herein in a generic sense and do not limit the number of terms, e.g., the first term can be one or more than one. In addition, "and/or" in the specification and claims means at least one of connected objects, a character "/" generally means that a preceding and succeeding related objects are in an "or" relationship.

A terminal performs cell search in a New Radio (NR) network of a fifth Generation Mobile Communication Technology (5th Generation Mobile Communication Technology, abbreviated as 5G) in two types: one is an initial cell search and the other is a cell search based on stored information.

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

If the terminal stores information that does not include cell information for the PLMN, the cell starts an "initial cell search".

For both types of cell search, if the terminal finds a "suitable cell", the terminal camps on this "suitable cell".

Wherein the "suitable cell" is a cell satisfying the following condition:

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

satisfying the S criterion of cell selection;

according to the latest information of a Non-Access Stratum (NAS) of a terminal, the cell is not set as 'cell selection forbidden, cell reselection forbidden';

according to the latest information of the terminal NAS, the Tracking Area Code (TAC) of the cell is not in the list of Forbidden Tracking Areas ".

Here, "suitable cell" does not guarantee that the terminal can access randomly successfully. If the terminal fails repeatedly in random access on the cell, the terminal cannot use the cellular communication function.

The NR Random Access procedure is classified into Contention-Based Random Access (CBRA) and non-Contention Random Access (CFRA). Both of the Random Access procedures involve Msg1 (i.e., Random Access Preamble) and Msg2 (i.e., Random Access Response). The random access failure of the terminal can also be caused if the Msg2 content received after the terminal sends Msg1 is not as expected. The specific reasons are analyzed as follows:

the relation between the cyclic shift value Ncs in the random access parameter in the NR system and the cell coverage radius is: when other parameters are unchanged, the cell coverage radius is proportional to Ncs. That is, the larger Ncs, 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 as an erroneous cyclic shift value when demodulation is performed at the base station side, so that the Random Access Preamble Identifier (RAPID) field of the MAC information received by the terminal in Msg2 does not match with the expectation, and the Random Access of the terminal fails. Moreover, since the cell signal strength is not matched with the parameter related to random access configured by the base station, the terminal will still repeat the random access process in the cell, so that the terminal cannot access not only the cell corresponding to the base station but also other cells, and the cellular communication service cannot be used for a long time.

In order to solve the above problem, embodiments of the present application provide a wireless access processing method, an information transmission device, and an electronic device. The method of the embodiment of the application relates to interaction between a terminal and a server. For convenience of understanding, in the following first embodiment, a processing procedure of the terminal after the random access failure is described from an overall interaction flow. Referring to fig. 1, the specific steps are as follows:

s101, the first terminal sends at least one piece of first information to a server under the condition that the random access of the first cell fails.

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 failure in the first cell.

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

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

The occurrence of the random access failure of the first terminal in the first cell includes but is not limited to: the first terminal generates n1 continuous random access failures in the first cell, wherein n1 is a positive integer greater than 1; the number of times of random access failures of the first terminal in the first cell exceeds the preset number in a period of time, the first terminal performs random access in the first cell, and random access success and random access failures alternately appear in a random access result.

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

information of a target cell, wherein the target cell comprises at least one of a first cell, a second cell and a third cell, the second cell is an adjacent cell of the first cell, the third cell is a cell which is successfully accessed by the first terminal for the latest N1 times, N1 is more than or equal to 1, and N1 is a positive integer;

first random access information;

time information of occurrence of random access failure;

geographical location information when the first terminal fails in random access.

The neighboring cell of the first cell, that is, the second cell, may be one or multiple, and is not limited herein. The third cell may be one cell or a plurality of cells, and is not limited herein.

It should be noted that the first terminal sends the information of the second cell and/or the information of the third cell to the server, and the purpose is to provide the reference information to the server, that is, the server may instruct the second terminal in the second group of terminals to select the second cell or the third cell to camp on, but not camp 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 point information;

a Physical Cell Identity (PCI);

a cell identity;

signal strength;

tracking area information of the Tracking area;

core Net information of the Core network;

the located radio access network Area RAN Area information.

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

a number of consecutive attempts of random access;

a random access result indicating a random access failure.

Here, the geographical location information when the random access failure occurs for the first terminal 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.

And S102, the server determines the second information and a first area corresponding to the random access failure according to the first information.

It should be appreciated that for a terminal that is within the first area and has not yet attempted random access in the first cell, the result will fail if access to the first cell is attempted.

information of a first cell;

cell restriction time information corresponding to the second terminal;

a first region.

S103, the server sends second information to a second group of terminals in the first area, the second group of terminals comprises M second terminals, M is larger than or equal to 1, and M is a positive integer.

It should be noted that the location where the first terminal is located when the random access failure occurs is located in the first area, where the first group of terminals belongs to the second group of terminals, that is, the first group of terminals is a subset of the second group of terminals.

Here, after receiving the second information, the second terminal may know, through the second information, information of a cell in which the terminal in the first area has failed in random access, that is, 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 time information of restriction processing 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 appreciated that the cell restriction duration may be timed from the time the second terminal receives the second information, for a restriction preset duration. The cell restriction end time corresponding to the second terminal is a future time, for example, the second information transmitted by the server at 10 am, and 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 herein.

If the second information includes the first area, the purpose is to make the second terminal judge whether the current position is in the first area after receiving the second information, if so, the step S104 is executed; if the second information is not in the first area, the second information is ignored and no processing is carried out. The purpose of this is to save resources by omitting the restriction process on the first cell for a terminal that is still in the first area when the server receives the first information but is not in the first area when the server receives the second information.

And S104, the second terminal limits the residence or access on the first cell based on the second information.

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

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

prohibiting camping in the first cell;

forbidding random access in the first cell;

the number of times of random access attempts in the first cell does not exceed N2, N2 is more than or equal to 1, and N2 is a positive integer;

the priority associated with the first cell is adjusted down.

It should be noted that, in the radio access processing method in the embodiment of the present application, information after a small part of terminals (i.e., a first group of terminals) fails to perform random access on a cell is utilized, and a server helps a large part of terminals (i.e., a second group of terminals) in an area (i.e., a first area) to avoid the cell in advance, and do no residence or random access in the cell as little as possible, so that time cost for the large part of terminals in the area to repeatedly attempt random access in the cell is saved, so that the second terminal attempts to access a cell with a stronger signal in another cell, and cellular communication quality of the terminals in the area is ensured.

On the basis, the method further comprises the following steps:

and after the limit on the first cell reaches the preset time or the specified time and the limit on the residence or access of the first cell is removed, the third group of terminals in the second group of terminals tries random access to the first cell to obtain a random access result.

And if the random access is successful and the continuous trial times are less than or equal to the preset times, 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 random access success of the second terminal.

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

Then, the terminals in the fourth group of terminals receive the fourth information sent by the server; and releasing the restriction processing of the residence or the access on the first cell according to the fourth information.

After a part of terminals in the first area release the restriction processing of residing on or accessing the first cell and the attempt to access the first cell is successful, it is indicated that the random access function of the first cell returns to normal, and through the above processing, the terminals in the area (i.e. the second area) corresponding to the area (i.e. the second area) where the random access function of the first cell returns to normal all release the restriction processing of residing on or accessing the first cell, so that the first cell can be used as a candidate cell for residing on or accessing randomly as soon as possible, thereby providing more possibility for better cellular communication quality.

The method provided by the embodiment of the present application is described in detail below from the perspective of a single-sided entity by referring to the specific embodiment and an application scenario thereof.

Fig. 2 is a schematic flowchart of a wireless access method according to an embodiment of the present application. The method is executed by the second terminal, and the implementation process of the method is described in detail below with reference to the figure.

Step 201, a second terminal receives second information sent by a server, wherein the second terminal is a terminal in a second group of terminals in a first area, and the first area and the second information are determined according to the first information; the first information is used for indicating information related to random access failure of a first terminal, and the first terminal is a terminal with random access failure in a first cell.

information of a first cell;

cell restriction time information corresponding to the second terminal;

a first region.

It should be noted that, after receiving the second information, the second terminal may know, through the second information, information of a cell in which the terminal in the first area fails to perform random access, that is, information of the first cell.

If the second information includes the first area, the purpose is to enable the second terminal to judge whether the current position of the second terminal is in the first area after receiving the second information, and if the current position of the second terminal is in the first area, the step 202 is executed; if the second information is not in the first area, the second information is ignored and no processing is carried out. This is done to save resources by omitting the restriction process on the first cell for a terminal that is still in the first area when the server receives the first information but is not already in the first area when the server receives the second information.

And step 202, the second terminal limits the residence or access on the first cell based on the second information.

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

prohibiting to reside in a first cell;

forbidding random access in the first cell;

the priority associated with the first cell is adjusted down.

Here, prohibiting camping on the first cell refers to prohibiting cell selection and/or cell reselection on the first cell.

The lowering of the priority associated with the first cell specifically means that the priority associated with the first cell is lowered when the second terminal performs at least one of cell selection, cell reselection and random access.

In the wireless access processing method of the embodiment of the application, the second terminal in the second group of terminals limits the camping or accessing of the second terminal on the first cell by using the indication after the processing of the relevant information of the random access failure of the first terminal by the server, namely the second information, so that the first cell can be avoided in advance, and the camping or the random accessing of the second terminal in the first cell is not performed or is performed as little as possible, thereby reducing the time cost for the second terminal to repeatedly perform the random access attempt in the first cell, enabling the second terminal to attempt to access the cell with stronger signals of other cells, and further ensuring the cellular communication quality of the terminal in the cell.

information of a target cell, wherein the target cell comprises at least one of a first cell, a second cell and a third cell, the second cell is a neighboring cell of the first cell, the third cell is a cell which is successfully accessed by the first terminal for the latest N1 times, N1 is more than or equal to 1, and N1 is a positive integer;

first random access information;

time information when a random access failure occurs;

Here, the meaning explanation of the above information can be detailed in the embodiment part shown in fig. 1, and is not repeated here.

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

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

a 1: the second terminal transmits third information to the server when determining that the first condition is satisfied.

The first condition comprises that the second terminal releases the limit processing of the resident or access of the first cell and then the random access is successful in the first cell; the third information is used for determining a second area and fourth information corresponding to the successful random access.

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

information of a first cell;

second random access information;

time information of successful random access;

and the second terminal generates the geographical position information when the random access is successful.

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

a number of consecutive attempts of random access;

a random access result indicating that the random access is successful.

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

The third information is used for the server to determine, based on the third information, a second area and fourth information corresponding to successful random access, and to send the fourth information to a fourth group of terminals in the second area.

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

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

information of a first cell;

a second region.

Here, if the fourth information includes information of the first cell, the purpose of the fourth information is to indicate a terminal in the fourth group of terminals, and the first cell is a cell that can be successfully accessed, the first cell may be a candidate cell for camping or random access.

If the fourth information comprises the second area, the purpose is to enable the terminals in the fourth group of terminals to judge whether the current position of the terminals is still in the second area after receiving the fourth information, if the terminals are in the second area, the limitation processing on the first cell can be immediately removed, the first cell is taken as a resident or randomly accessed candidate cell, and whether the cell limitation time reaches or comes does not need to be considered; and if the second information is not in the second area, ignoring the fourth information.

The purpose of this is to enable the server to immediately release the restriction processing on the first cell by the terminal which is still in the second area when receiving the third information and which is still in the second area when receiving the fourth information, so that the terminal in the second area can use the cellular communication service through the first cell as soon as possible.

In an optional implementation manner, if a second terminal is a terminal in a fourth set of terminals, the fourth set of terminals is a subset of the second set of terminals; the method of the embodiment of the application further comprises the following steps:

b 1: and receiving fourth information sent by the server.

b 2: and releasing the limitation processing of the residence or the access on the first cell according to the fourth information.

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

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

allowing camping on the first cell;

allowing random access in a first cell;

the priority associated with the first cell is adjusted up.

Here, allowing camping on the first cell refers to allowing cell selection and/or cell reselection on the first cell.

The increasing of the priority level related to the first cell specifically means that the priority level related to the first cell is increased when the second terminal performs at least one of cell selection, cell reselection and random access.

It is to be explained that the priority associated with the first cell comprises at least one of:

a priority of the first cell;

the priority of the frequency point of the first cell;

priority of a Radio Access Technology (RAT) in which the first cell is located;

priority of the public land mobile network PLMN the first cell is in.

Fig. 3 is a schematic flow chart of an information transmission method according to an embodiment of the present application. The method is executed by a server, and the implementation process of the method is described in detail below with reference to the figure.

Step 301, a server obtains first information sent by a first group of terminals, where the first group of terminals includes N first terminals, the first terminals are terminals that have random access failures in a first cell, the first information is used to indicate information related to the random access failures of the first terminals, N is greater than or equal to 1, and N is a positive integer.

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

first random access information;

time information when a random access failure occurs;

Step 302, the server determines the second information and a first area corresponding to the random access failure according to the first information.

information of a first cell;

cell restriction time information corresponding to the second terminal;

a first region.

Here, the server may estimate the first area corresponding to the random access failure according to the geographical location information of the first terminal when the random access failure occurs in the first information.

The cell restriction time information corresponding to the second terminal is cell restriction time information corresponding to the second terminal, the restriction target of which 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 if a terminal in the first area (hereinafter, a terminal in the second group of terminals) attempts to access the first cell, the result is that all the terminals will fail. In order to save the time cost of most terminals in the area repeatedly trying random access in the cell and guarantee the cellular communication quality of the terminals in the area, the server generates second information to indicate that the second group of terminals currently in the first area restricts the camping or random access in the first cell.

Step 303, the server sends second information to a second group of terminals in the first area, where the second group of terminals includes M second terminals, M is greater than or equal to 1, and M is a positive integer.

Here, the server transmits second information to a second group of terminals within the first area, the purpose of which is to instruct the second group of terminals currently within the first area to restrict camping or random access in the first cell based on the second information.

It should be noted that, in the embodiment of the present application, one server may be used, or multiple servers may be used, that is, the processing steps may be completed by one server or multiple servers, and are not limited specifically herein. When the system is completed by a plurality of servers, different processing tasks are distributed on different servers and completed through division and cooperation among the servers. For example, one server is responsible for collecting first information, and the other server is responsible for making a calculation decision on the collected first information to obtain second information and a first area corresponding to random access failure; and the other server is responsible for sending second information to a second group of terminals in the first area.

In the information transmission method of the embodiment of the application, the server determines the second information and a first area corresponding to the random access failure by using first information sent by a first group of terminals after the random access failure occurs in a first cell, and sends the second information to a second group of terminals in the first area to indicate that the second group of terminals currently in the first area limit the residence or the random access in the first cell based on the second information, so that most of the terminals in the first area, namely the second group of terminals, are helped to avoid the cell in advance, and the residence or the random access in the first cell is not performed or is performed as little as possible, thereby saving the time cost of the second group of terminals in the first area repeatedly trying the random access in the first cell, and ensuring the cellular communication quality of the terminals in the first area.

It should be noted that, the server not only receives information sent by some terminals after the random access failure in the first cell, but also receives information sent by some other terminals after the random access failure in other cells, so in order to distinguish terminals with random access failures in different cells and facilitate subsequent processing of information, the server needs to group the terminals according to the cells with random access failures.

In an optional implementation manner, in step 301 of the method in this embodiment, the obtaining, by the server, first information sent by a first group of terminals includes:

step 3011, the server receives fifth information sent by T third terminals, where the third terminals are terminals that have random access failure in the camped cell, the fifth information is used to indicate information related to the random access failure of the third terminals, T is greater than or equal to N and greater than or equal to 1, and T is a positive integer.

Here, the third terminal generally refers to a terminal in which a random access failure occurs on a camped cell. The cell in which the third terminal resides may be the first cell or another cell.

Step 3012, the server divides the third terminal satisfying the second condition into a first group of terminals as the first terminal based on the fifth information.

Wherein the second condition comprises at least one of:

the resident cells are the same and are all first cells;

the difference value between the time of the random access failure of the third terminal in the first cell and the first time value is in a first preset range, the first time value is a time value which is positioned in the middle of a first number sequence, or the average time value of a first set, the first number sequence is formed by arranging the time of the random access failure of T third terminals in the first cell according to the time sequence, and the first set comprises the time of the random access failure of the T third terminals in the first cell;

the difference between the geographic position of the third terminal and the first geographic position is within a second preset range, the first geographic position is the geographic position which is located in the middle of the second array or the average geographic position of the second set, the second array is formed by arranging the geographic positions of the T third terminals according to the distance sequence with the first cell, and the second set comprises the geographic positions of the T third terminals.

Here, if the second condition includes that the difference between the time when the random access failure occurs in the first cell and the first time value of the third terminal is within the first preset range, the method refers to that a plurality of third terminals close to each other in time when the random access failure occurs in the first cell are taken as first terminals, the third terminals are divided into a first group of terminals, and the third terminals far away from each other in time are excluded, so that the server subsequently determines that the second information and the first area are more accurate and more time-efficient according to the first information sent by the first group of terminals.

If the second condition includes that the difference between the geographic position of the third terminal and the first geographic position is within a second preset range, the third terminals with the different geographic positions and closer geographic positions are taken as the first terminals and divided into the first group of terminals, and the third terminals with the different geographic positions are excluded, so that the server determines the second information and the first area more accurately according to 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 takes it as the first information sent by the first group of terminals.

It should be noted that, communication attributes of different terminals are different, and corresponding base stations matched for providing services for the terminals are also different. If the base station corresponding to the first cell supports the 5G technology and the terminal is a terminal that does not support the 5G technology, or if the PLMN to which the base station corresponding to the first cell belongs is different from the PLMN registered by the terminal, some terminals cannot access the first cell due to their own communication attributes. However, there may be terminals in the first area that cannot access the first cell due to their own communication attributes, and in order to save network resources, the server needs to divide the terminals in the first area that match the first information into a group based on the first information, and only send the second information to the group of terminals.

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

c1, the server acquires P fourth terminals in the first area, wherein P is larger than or equal to M and is a positive integer.

And c2, the server divides a fourth terminal meeting a third condition into a second group of terminals as a second terminal according to the first information, wherein the third condition is that the communication attribute of the fourth terminal is matched with the first information, and the communication attribute comprises the communication capability supported by the terminal and/or the communication state of the terminal.

The communication capability supported by the terminal refers to a RAT to which the random access failure corresponds. The terminal state of the terminal refers to at least one of cell information, frequency point information and PLMN (public land mobile network) where the terminal resides or is accessed.

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 restricts the camping or accessing in the first cell according to the second information.

It should be understood that the restriction process for the first cell is not permanent, and the restriction may be released when the restriction time reaches a preset duration or reaches a preset end time (i.e., a certain time in the future), and then the terminal may again attempt to access the first cell. Here, after the second terminal releases the restriction processing on the camping or access of the first cell and when the random access of the first cell is successful, the second terminal transmits third information to the server, so that the server determines a second area and fourth information corresponding to the successful random access based on the third information and transmits the fourth information to a 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 third information sent by a third group of terminals, the third group of terminals are a subset of the second group of terminals, the second terminals in the third group of terminals meet a first condition, and the first condition comprises that the second terminals succeed in random access in the first cell after the second terminals remove the limit processing on the residence or access of the first cell.

second random access information;

time information of successful random access;

and the second terminal which succeeds in random access generates geographical position information when succeeding in random access.

Here, the meaning of each information is explained, and details can be seen in the embodiment part shown in fig. 2, which is not described again here.

d2, according to the third information, determining the fourth information and the second area corresponding to the success of random access.

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

information of a first cell;

a second region.

The purpose of this is to enable the terminal in the second area to immediately release the restriction processing on the first cell when the server receives the third information and the terminal in the second area receives the fourth information, so that the terminal in the second area can use the cellular communication service through the first cell as soon as possible.

d3, sending fourth information to a fourth set of terminals in the second area, the fourth set of terminals being a subset of the second set of terminals.

Here, the server transmits fourth information to the fourth terminal within the second area, with the purpose of causing the second terminal of the fourth group of terminals to release the restriction process of camping on or accessing the first cell according to the fourth information, so as to cause the fourth group of terminals to use the cellular communication service as soon as possible.

Optionally, the second terminal of the third set of terminals further satisfies a fourth condition comprising at least one of:

the difference value between the time when the second terminal successfully performs random access in the first cell and the second time value is within a third preset range, wherein the second time value is a time value which is positioned in the middle of a third sequence or an average time value of a third set, the third sequence is formed by arranging all the second terminals in the third group of terminals in the time sequence when the random access in the first cell successfully occurs, and the third set comprises the time when the random access in the first cell successfully occurs by all the second terminals in the third group of terminals;

the difference between the geographic position of the second terminal and the second geographic position is within a fourth preset range, the second geographic position is the geographic position located in the middle of a fourth array, or the average geographic position of a fourth set, the fourth array is formed by arranging the geographic positions of all the second terminals in the third group of terminals according to the distance sequence with the first cell, and the fourth set comprises the geographic positions of all the second terminals in the third group of terminals.

In this implementation, the third group of terminals further needs to satisfy the fourth condition to enable the server to determine the fourth information and the second area more accurately according to the third information sent by the third group of terminals.

Step 401, a first terminal sends at least one first message to a server under the condition that a random access failure occurs in a first cell, wherein the first terminal is a terminal in a first group of terminals; the first information is used for determining the second information and a first area corresponding to the random access failure.

Optionally, the first terminal is in communication connection with the server through the internet, a local area network, or the internet of things.

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

Optionally, the at least one first information comprises: the information related to the random access failure of the first terminal occurring in the first cell last time, or the information related to the random access failure of the first terminal occurring in the first cell other than the last time.

It is to be understood that the at least one first message is selected as a message related to the last or last few times of the random access failure of the first terminal in the first cell, in order to make the second message and the first area determined by the server based on the first message more time-efficient.
