Description

Communication processing method, device, communication equipment and readable storage medium

Technical Field

The application belongs to the technical field of communication, and particularly relates to a communication processing method, a device, a communication device, a readable storage medium, a device and a communication device.

Background

Due to reflection on the water surface (e.g. on the water surface of lake water or sea water) etc. the downgoing coverage of a cell towards the water surface is much larger than towards the land, resulting in that terminals further to shore (e.g. lake or strait) can also receive stronger signals and thus stay in the cell, a phenomenon called remote access.

In the scenario of remote access, due to the fact that the actual geographic location of the terminal is inconsistent with the geographic location of the cell in which the terminal is remotely accessed, effective services cannot be provided for the terminal, for example, if the geographic area covered by the cell a is determined to have a certain risk (such as virus infection or infection risk, etc.), a risk prompt needs to be performed on a user accessing the cell a, at this time, if the terminal in the cell a is remotely accessed, the terminal will be caused to also receive the risk prompt, and in fact, the terminal does not enter the geographic area covered by the cell a, thereby causing an error transmission of the risk prompt and causing serious confusion to the risk management and control work.

It is to be understood that the terms so used are interchangeable under appropriate circumstances such that the embodiments of the application are capable of operation in sequences other than those illustrated or otherwise described herein, and that the "first" and "second" distinguishing between objects generally are not limited in number to the extent that the first object may, for example, be one or more. Furthermore, in the description and claims, "and/or" means at least one of the connected objects, and the character "/" generally means a relationship in which the associated object is an "or" before and after.

It should be noted that the techniques described in the embodiments of the present application are not limited to long term evolution (Long Term Evolution, LTE)/LTE evolution (LTE-Advanced, LTE-a) systems, but may also be used in other wireless communication systems, such as code divisionMultiple access (Code Division Multiple Access, CDMA), time division multiple access (Time Division Multiple Access, TDMA), frequency division multiple access (Frequency Division Multiple Access, FDMA), orthogonal frequency division multiple access (Orthogonal Frequency Division Multiple Access, OFDMA), single-carrier frequency division multiple access (Single-carrier Frequency Division Multiple Access, SC-FDMA), and other systems. The terms "system" and "network" in embodiments of the application are often used interchangeably, and the techniques described may be used for both the above-mentioned systems and radio technologies, as well as other systems and radio technologies. The following description describes a New air interface (NR) system for purposes of example and uses NR terminology in much of the description that follows, but these techniques are also applicable to applications other than NR system applications, such as generation 6 (6) ^th Generation, 6G) communication system.

In order to facilitate understanding of the embodiments of the present application, the following technical points are first described:

1. Regarding cell selection and cell reselection

Mobility of UEs in radio resource control (Radio Resource Control, RRC) Idle (Idle) state and RRC Inactive (active) state is achieved by cell selection and cell reselection mechanisms. Cell selection is the fast selection of one suitable cell for camping and cell reselection is the reselection of another "better" cell for camping in the case of the current cell camping.

In the cell selection and reselection procedure, the cells are divided into an acceptable cell (acceptable cell), a suitable cell (acceptable cell), a reserved cell (reserved cell) and a barred cell (barred cell), which respectively represent the following meanings:

acceptable cell: the UE may camp on, but may only be able to obtain limited service cells (initiate emergency call and receive earthquake tsunami warning system (Earthquake and Tsunami Warning System, ETWS)/commercial mobile warning system (Commercial Mobile Alert System, CMAS) notification). An acceptable cell should meet the following requirements:

-the cell is not barred;

cell selection or cell reselection conditions (alternatively referred to as cell selection or cell reselection criteria, or S criteria) are met;

Suitable cell: a cell that can provide normal service to a UE, the appropriate cell should satisfy the following criteria:

the public land mobile network (Public Land Mobile Network, PLMN) to which the cell belongs is in accordance with the UE subscription data (is the PLMN selected by the UE, the registered PLMN or equivalent PLMN)

-meeting a cell selection or cell reselection condition;

-the cell is not a forbidden cell;

-the cell is part of at least one Tracking Area (TA) and the TA is not in the list of "Tracking Area (Forbidden Tracking Areas for Roaming) where roaming is prohibited";

forbidden cell: indicating cell prohibition in the system information;

reserved cell: cell reservation is indicated in the system information.

2. Criteria for cell selection

Cell selection criteria: s is S _rxlev >0 and S _qual >0, wherein

S _rxlev ＝Q _rxlevmeas –(Q _rxlevmin +Q _{rxlevminoffset} )–P _compensation -Qoffset _temp ；

S _qual ＝Q _qualmeas –(Q _qualmin +Q _{qualminoffset} )-Qoffset _temp 。

The meaning of each parameter is as follows:

S _rxlev : cell selection pilot signal reception level (dB);

Q _rxlevmeas : pilot signal received power measurements (Reference Signal Receiving Power, reference signal received power, RSRP) of the cells;

Q _rxlevmin : minimum required received power level (dBm);

Q _{rxlevminoffset} : relative to Q _rxlevmin For use in the calculation of Srxlev;

P _compensation : the power offset value of the UE is determined according to the maximum transmission power of the UE.

Qoffset _temp : a temporary offset applied to a cell, for example, when a terminal connects to the cell, fails connection. In the related art, a connEstFailOffset cell is defined in a system information block (System information block, SIB) 1, and if the connEstFailOffset cell is not present in SIB1, qoffset is considered _temp Is infinite. If SIB1 is configured with a connestfailoecontrol cell and the T300 timer times out the connEstFailCount times continuously in one cell, then for the period indicated by connEstFailOffsetValidity, connEstFailOffset is used as qoffsetemp. The T300 timer is defined as the maximum waiting time for the terminal to receive RRC setup (RRCSetup) or RRC reject (rrcrreject) after sending an RRC setup request (RRCSetup request).

Parameter definition: connEstFailCount: the terminal detects the number of times T300 expires on the same cell before connEstFailOffset is applied. connEstFailOffset: the related art is used to represent the parameter "qoffsetemp". If this field does not exist, then "Qoffsetemp" should use an infinite value. connEstFailOffsetValidity: the terminal applies the amount of time of connEstFailOffset before removing the offset from the cell evaluation. The value s30 corresponds to 30 seconds and the value s60 corresponds to 60 seconds.

Square: cell selection pilot signal quality level (dB);

Q _qualmeas : a pilot signal quality measurement (reference signal received quality (Reference Signal Receiving Quality, RSRQ)) of the cell;

Q _qualmin : minimum required received power level (dBm);

Q _{qualminoffset} : relative to Q _qualmin For an offset of S _qual Is calculated by the computer.

3. Regarding the cell reselection criterion (S criterion):

when a better cell appears to serve the terminal, the terminal can reselect to the better cell through a cell reselection procedure. Cell reselection is a number of situations, including common frequency cell reselection and different frequency cell reselection.

Common frequency and same priority different frequency cell reselection criteria:

the serving cell ranking criterion Rs and the neighbor cell ranking criterion Rn are defined by the following equation,

R _s ＝Q _meas,s +Q _hyst -Qoffset _temp

R _n ＝Q _meas,n –Q _offset -Qoffset _temp

wherein:

·Q _meas : RSRP measured at cell reselection

·Q _offset : reselection offset of neighbor cell, if configured with Q for same frequency cell _offsets,n Then is Q _offsets,n And 0 when not configured. If Q is configured for inter-frequency cells _offsets,n Then is Q _offsets,n +Q _{offsetfrequency} Otherwise is Q _{offsetfrequency} 。

·Qoffset _temp : see description at cell selection.

UE calculates R of serving cell _s R of adjacent cell _n The UE should reselect to the highest ranked cell (e.g., the cell with the largest R value);

4. high priority inter-frequency cell reselection criteria (R criteria):

And when the following conditions are met, reselecting to a high-priority different frequency or different system frequency point:

different frequencies or different system cells satisfy S _rxlev >ThreshX, highP duration TreselectionRAT;

the terminal resides in the current cell for more than 1 second.

5. Low priority inter-frequency cell reselection conditions:

and when the following conditions are met, reselecting to a low-priority different frequency or different system frequency point:

the serving cell satisfies S within the treselection RAT time _rxlev <ThreshServing, lowP and different frequency or different system cells satisfy S _rxlev >ThreshX,LowP；

The terminal resides in the current cell for more than 1 second.

6. Contention-based random access (random access channel (Random Access Channel, RACH)) procedure

When the terminal enters the RRC connected state from the RRC idle state or the RRC deactivated state, the terminal first needs to perform a contention based random access procedure to acquire uplink synchronization, acquire a Cell radio network temporary identity (Cell-Radio Network Temporary Identifier, C-RNTI), and obtain uplink resources to transmit message 3 (msg 3). The contention-based random access procedure is as follows:

step 1: the terminal transmits a random access preamble (random access preamble).

The main function of the random access preamble is to tell the base station that there is a random access request and to enable the base station to derive the TA based on the random access preamble so that the base station informs the TA to the terminal via the random access response (Random Access Response, RAR) of step two.

Step 2: the base station transmits a random access response;

after the terminal sends the Random Access preamble, it will monitor the physical downlink control channel (Physical Downlink Control Channel, PDCCH) in the RAR time window (RA Response window) to receive the RAR corresponding to the Random Access RNTI (RA-RNTI). If the RAR replied by the base station is not received in the RAR time window, the random access procedure is considered to be failed. The RAR message contains TA, a temporary cell radio network temporary identity (temp C-RNTI) allocated to the terminal, and uplink resources allocated for transmitting Msg 3.

Step 3: the terminal sends Msg3;

the Msg3 needs to include: each terminal is uniquely identified, which will be used for contention resolution (contention resolution) of step 4. In the scenario that the terminal enters the RRC connection state from the RRC idle state, the Msg3 further includes an RRC establishment request message, where the unique identifier of the terminal is a terminal identifier (for example, a system architecture evolution-temporary mobile subscription identifier (System Architecture Evolution-Temporary Mobile Subscription Identifier, S-TMSI)) provided by a Non-Access Stratum (NAS) layer of the terminal, or a random number; in the scenario that the terminal enters the RRC connection state from the RRC deactivated state, msg3 contains an RRC resume request message, and the unique identifier of the terminal is a resume identifier allocated by the base station.

Step 4: the base station transmits a contention resolution message (or described as message 4 (Msg 4));

the terminal will have a unique identification at Msg3 that carries the terminal. The base station will carry the unique identification in Msg4 in the contention resolution mechanism to designate the terminals that are winning contention. While other terminals that are not winning in contention resolution will re-initiate random access.

7. With respect to Registration Area Update (RAU)

In the fifth generation mobile communication technology (5th Generation,5G) system, after the terminal is started, the terminal registers with the core network, the core network sends a tracking area list (Tracking Area List, TA list) to the terminal, and as the terminal moves, when the terminal moves out of the range of the TA list, the terminal needs to initiate an RAU procedure to the core network to update the registration area to obtain a new TA list. Therefore, the core network at least knows that the terminal is in the TA list range, and when the terminal in the RRC idle state needs to be paged, the core network pages in the TA list range.

Specifically, for example, in the RRC idle state or the RRC deactivated state, after the terminal performs cell selection or cell reselection to reside in a new cell, an Access Stratum (AS) of the terminal may read system information of the cell, thereby obtaining a TAC value to which the cell belongs, and submit the TAC value to a NAS layer of the terminal. If the TAC of the cell is not in Ta list, the NAS of the terminal instructs the AS of the terminal to enter RRC connected state, and initiates an RAU procedure to the core network, which sends a new Ta list to the terminal,

A similar mechanism is also employed in long term evolution (Long Term Evolution, LTE) systems, except that in LTE systems it is referred to as tracking area update (Tracking Area Update, TAU).

8. Remote access problem

Due to reflection from the water surface (such as lake water or sea water), etc., the downgoing coverage of a cell in the water surface direction is far greater than that in the land direction, resulting in a stronger signal being received by a far-distant landline terminal and thus residing in the cell.

Due to the long distance, when uplink access is performed to the terminal on the shore to initiate RACH, the terminal always fails to access due to uplink power limitation, i.e. the T300 timer always times out. But due to the good downlink signal, the terminal on the shore will always reselect to the cell.

For example, by introducing Qoffset _temp Parameters (see description in section of cell selection and cell reselection) allow a terminal on shore to avoid selecting or reselecting to the cell as much as possible after one or more access failures _temp The parameters can be used after one or more failures of uplink access, but uplink access can be successfully performed in a remote access scene, so that the problem of remote access cannot be thoroughly solved.

After the terminal performs cell reselection to a new cell, the AS of the terminal reads the system information of the cell to obtain a tracking area code (Tracking Area Code, TAC) to which the cell belongs, and then the AS of the terminal submits the TAC to a Non-Access-Stratum (NAS) layer of the UE. The NAS of the terminal determines whether the TAC is in the current tracking area list (TA list). If the TAC is not in the current TA list, the NAS layer of the terminal triggers an RAU procedure, specifically, the NAS layer of the terminal instructs the access layer of the UE to initiate an RRC connection establishment procedure, the AS layer of the terminal initiates an RACH procedure (acquires a TA value) first, and then, in an RRC establishment complete message, the NAS protocol data unit (Protocol Data Unit, PDU) is carried, where the NAS PDU is an RAU message. The terminal will still perform RAU procedure at the base station remotely accessed even if the terminal adopts Qoffset for the cell in the subsequent cell selection or cell reselection _temp Nor does it solve the problem of determining users far from the risk area as users within the risk area, thereby affecting the accuracy of risk management.

The following describes in detail a communication processing method, a device, a communication apparatus, and a readable storage medium provided by the embodiments of the present application through some embodiments and application scenarios thereof with reference to the accompanying drawings.

Referring to fig. 2, an embodiment of the present application provides a communication processing method, which is applied to a terminal, and includes the specific steps of: step 201, or step 202 and step 203.

In one embodiment, the method shown in FIG. 2 includes: step 201. In step 201, the terminal performs cell selection or cell reselection in a first cell according to a first criterion, the first criterion comprising: the terminal preferentially selects or reselects to a cell with a first cell group identifier; the first cell is a service cell of the terminal when performing cell selection or cell reselection evaluation, and the first cell group identifier is an identifier of a cell group to which the first cell belongs;

it may be appreciated that when the terminal performs cell selection or cell reselection at the first cell, the cell having the first cell group identifier has the highest cell selection or cell reselection priority, and when there are a plurality of cells having the first cell group identifier, one cell may be selected from among them to perform cell selection or cell reselection according to selection parameters such as signal quality of each cell.

For example, when the terminal performs cell selection or cell reselection evaluation, the serving cell is cell1 (cell 1), a first cell group of the cell1 is identified as an identifier a, a lake (or a channel) is arranged between the cell1 and the cell2 (cell 2), due to reflection of the water surface, the downlink coverage of the cell2 towards the water surface is far larger than that towards the land, so that the terminal on the far lake opposite bank can also receive a stronger signal, and thus stay in the cell2, and when the terminal performs cell selection or cell reselection according to a first criterion in the cell1, the terminal preferentially selects or reselects to a cell 3 with a first cell group identifier (for example, the cell1 and the cell 3 belong to the first cell group, and the first cell group identifier is identified as an identifier a), but not selects or reselects to the cell2, so that the terminal can be prevented from being remotely accessed to the cell2, and the accuracy of risk management is improved.

It will be appreciated that the arrangement manner of the first cell group in the embodiment of the present application is not specifically limited, for example, the location of the cell may be considered, and for example, a cell (for example, a neighboring cell) on the same shore as the cell1 may be set to belong to the same cell group (i.e., the first cell group).

In another embodiment, the method shown in FIG. 2 includes: step 202 and step 203.

In step 202, a terminal receives first information sent by a first communication device;

in step 203, the terminal performs cell selection or cell reselection according to the first information, where the terminal is determined by the first communication device to be a first type of terminal, and the first type of terminal includes: remote access terminals, or terminals within a designated area.

In this embodiment, assuming that the type of the terminal is a remote access terminal, it means that the terminal may establish a connection with the first communication device by means of remote access.

In this embodiment, it is assumed that the type of the terminal is a terminal in the designated area, which indicates that the terminal is located in the designated area, and the terminal may establish a connection with the first communication device through a remote access manner.

In this embodiment, the above specified area may be referred to as a specified cell (cell).

In an exemplary embodiment, the current geographic location of the terminal actually belongs to the coverage area of the cell1, and there is a lake (or a channel) between the cell1 (cell 1) and the cell2 (cell 2), and due to reflection of the water surface, the downlink coverage of the cell2 in the direction of the water surface is far greater than that in the direction of the land, so that the terminal on the shore of the far lake can also receive a strong signal, and thus reside in the cell2, that is, the terminal is determined by the first communication device in the cell2 to be a first type terminal (equivalent to the terminal determined to be remotely accessed by the terminal or the terminal of the cell 1), the terminal receives the first information sent by the first communication device, and performs cell selection or cell reselection according to the first information, so that when the terminal is determined to belong to the first type terminal, the terminal can be instructed to perform cell selection or cell reselection, and the terminal can avoid selection or reselection to the cell2 as much as possible according to the parameters in the first information, so that the risk of remote access can be prevented as much as possible, and the risk control can be improved.

In this embodiment, the designated area may also be referred to as an area marked with a certain label, such as a risk area, a seal control area, a management and control area, a precaution area, an interference area, an infection area, etc., where the risk area refers to an area within the area that belongs to risk control, the seal control area refers to an area within the area that belongs to seal control, personnel in the forbidden area move outside the area, and the management and control area refers to an area that needs to strictly control the flow of personnel.

In the embodiment of the application, the judging mode of the specific label, the naming of the specific label and the shape of the area are not limited. Further, different grades may be set for the specific tags, such as a high risk area, a low risk area, etc.

Taking the designated area as a high risk area as an example, the current geographic position of the terminal actually belongs to the coverage range of the cell1, and a lake (or a strait) exists between the cell1 (cell 1) and the cell2 (cell 2), wherein the cell1 belongs to the coverage range of the high risk area, the cell2 belongs to the range of the correct area, and due to reflection and other reasons of the water surface, the downlink coverage of the cell2 towards the water surface direction is far larger than that towards the land direction, so that the terminal on the shore of the far lake can also receive a stronger signal, and thus the terminal stays in the cell2, and the terminal possibly cannot receive the risk prompt information broadcasted by the cell1 due to the fact that the cell2 belongs to the normal area.

Referring to fig. 6, for a terminal in an RRC idle state, when the terminal enters an RRC connected state (for example, when a terminal selects a cell or reselects a cell, and the TAC of the cell is not in the current TA list of the terminal, the terminal needs to enter the RRC connected state to perform an RAU procedure), the flow is as follows:

Step 1: the terminal in the RRC idle state determines to enter an RRC connection state;

step 2: the terminal transmitting a random access preamble (Random Access Preamble) to the first communication device;

step 3: the first communication equipment acquires a TA value of a terminal;

step 4: the first communication device sending a random access response (Radom Access Response) message to the terminal;

step 5: the terminal sending an RRC setup request (RRC setup Request) message to the first communication device;

step 6: the first communication device sending a contention resolution (Contention Resolution) message to the terminal;

Example two

In this embodiment, the cells are grouped, each group of cells corresponds to a cell group identifier, and system information of the cells carries the cell group identifier of the cell. It will be appreciated that if the cells are grouped by region, each region corresponds to a region identifier, and the system information of the cell carries the region identifier.

The terminal illustratively maintains a cell group identity, and upon cell selection or cell reselection or handover of the terminal to a cell, the terminal updates the maintained cell group identity to the cell group identity of the cell.

In the case of cell selection or reselection, the terminal preferentially selects or reselects to a cell having a first cell group identity, and can select or reselect to a neighbor cell having no first cell group identity, which is the identity of the cell group to which the first cell belongs, only when there is no neighbor cell having the first cell group identity satisfying the cell selection or cell reselection S criteria, the first cell being the serving cell of the terminal when performing cell selection or cell reselection evaluation.

Optionally, the first cell group identity is carried in system information of the first cell (such as SIB 1).

Optionally, the system information may carry the first cell group identifier, for example, only the system information broadcast in the cells in the area where remote access may exist may carry the first cell group identifier. If the cell which does not broadcast the first cell group identification is selected or reselected, the cell group identification maintained by the terminal is changed to be null; when the maintained packet identity is empty, reselection is performed according to existing mechanisms.

Alternatively, the cell group identifier may include a TAC, but the system information of the cell includes an indication information for indicating that the above-mentioned cell selection or cell reselection mechanism is used, that is, when the terminal resides in the cell, the cell having the same TAC is preferentially selected or reselected when cell selection or cell reselection is performed;

Alternatively, the cell group identifier may be a newly introduced identifier, and if the newly introduced identifier is carried in the system information broadcasted by a certain cell, the terminal uses the cell selection or cell reselection mechanism described above.

It will be appreciated that in addition to the cell group identity, parameters indicating that there are administrative boundaries between particular cells may be carried in the system information, which may increase the difficulty of selection or reselection between particular cells.

In this embodiment, cells on the same side of a specific area (e.g., the strait area) broadcast the same cell group identity so that the terminal does not select or reselect to cells on the other side of the specific area as much as possible.

Example III

Referring to fig. 8, the specific steps are as follows:

step 2: the terminal sends a random access preamble to the first communication device;

step 3: the first communication device obtains a TA value of the terminal.

When the terminal initiates a RACH process from an RRC idle state to an RRC connected state in a first cell, the first communication device acquires a corresponding TA value, and the first communication device determines whether the terminal is a first type terminal or not based on the TA value.

Step 4: the first communication device transmits a random access response message to the terminal.

Step 5: the terminal sends an RRC establishment request message to the first communication equipment;

step 6: the first communication device sends a contention resolution message to the terminal;

step 8: the terminal sends an RRC establishment completion message to the first communication equipment;

step 9: the first communication device determines whether the terminal is a first type terminal or not through the TA value;

for example, the first communication device maintains a TA threshold internally, and when the TA value of the terminal is greater than the TA threshold, the first communication device determines that the terminal is a first type terminal, otherwise, the terminal is not the first type terminal.

It should be noted that step 9 may occur at any one of steps 3 to 10.

Step 10: the first communication equipment sends first information to the terminal;

step 11: and the terminal performs cell selection or cell reselection according to the first information.

After the terminal completes the RRC connection setup procedure (i.e., after the first communication device receives the RRC setup complete message), if the terminal is not a first type terminal, the first communication device sends Initial UE message a message to the second communication device according to the prior art; if the terminal is a first type terminal, the first communication device sends an RRC release message to the terminal, the RRC release message carrying first information, and the UE performs cell selection or cell reselection based on the first information.

The first information is used to instruct the terminal to perform cell selection or cell reselection, and when performing cell selection or cell reselection evaluation, the following rules are performed:

the terminal sets the first cell as the lowest considered cell for cell selection or cell reselection, i.e. as long as there are other suitable cells, cell selection or cell reselection to other cells, which may be included by the first information only if there are no other (not considered lowest) suitable cells, cell selection or reselection to the first cell is performed, or by subtracting an offset when calculating the R value of the first cell.

Optionally, the frequency of the first cell is regarded as the lowest frequency priority.

Alternatively, the first information may include a duration of a timer. The terminal starts the timer after receiving the first information, and applies the above rule to the first cell at the time of cell selection or cell reselection during the timer running. After the timer expires, the above rule is not executed.

Alternatively, the first cell may calculate the R value, i.e. Rs, as the serving cell, or the first cell may calculate the R value, i.e. Rn, as the neighbor cell.

Alternatively, the first information may include a first cell list (for example, when the terminal is considered as a first type of terminal in a first cell, the terminal is also considered as a first type of terminal to the cells in the first cell list), the terminal sets the cells in the first cell list as the cells with the lowest consideration for cell selection or cell reselection, or subtracts an offset when calculating the R value of the cells in the first cell list, so as to reduce RACH frequency and reduce resource overhead.

It should be noted that the first information is different from the redirection information. The redirection information is to let the terminal redirect to a cell of a designated frequency, and the first information is to let the UE perform cell selection or cell reselection and try to select or reselect to other cells.

It will be appreciated that in this embodiment, the terminal still selects the first cell to camp on, e.g. no other suitable cell exists. In order for the UE to initiate traffic:

optionally, the first communication device stores the system architecture evolution-temporary mobile subscription identifier (System Architecture Evolution-Temporary Mobile Subscription Identifier, S-TMSI (for example, the lower 9 bits of which are ng-5G-S-TMSI-Part2 in the RRC Setup Complete message and the upper 39 bits are ng-5G-S-TMSI-Part1 in the RRC Setup Request message) of the terminal for a period of time, if during the period of time, the terminal initiates RRC connection establishment in the first cell again, the first communication device determines from the S-TMSI that the terminal initiates RRC connection establishment again in the period of time, and then no RRC release message is sent any more, and allows the terminal to perform RAU and data transmission in the first cell establishment connection.

Optionally, when the terminal receives the first information and still selects the first cell to camp on, when the RRC connection establishment is initiated again, the RRC establishment request message or the RRC establishment complete message carries indication information, which is used to indicate that the terminal is the first type terminal, for example, an establishment cause value "remote access" is newly introduced in the RRC establishment request message, and a cell is newly introduced in the RRC establishment complete message, so that the base station does not send an RRC release message any more, and allows the UE to perform RAU and data transmission in the first cell to establish the connection.

Illustratively, cell1 (Cell 1) and Cell2 (Cell 2) are located on both sides of a particular area (e.g., strait), with both Cell1 and Cell2 managing terminals of the first type. After selecting or reselecting to the cell1 or the cell2, the terminal may initiate access again after cell selection or cell reselection because of the need to perform RAU after performing the random access procedure in the cell1 or the cell2, respectively. And this time the terminal may be released again as a first type of terminal.

In order to avoid that the terminal is released again, the terminal may send a connection establishment cause to the first communication device, e.g. the connection establishment cause comprises: and (5) remote access.

In the above example, to avoid the repeated random access procedure between cell1 and cell2, the terminal may instruct the source cell (Source Cell of cell reselection) or the last camped cell (the last camped cell) of the cell reselection upon the first connection establishment, which may trigger execution of embodiment 1 or embodiment 3.
