Description

Processing method and device of access control timer, terminal and network side equipment

Technical Field

The present invention relates to the field of communications technologies, and in particular, to a method, an apparatus, a terminal, and a network side device for processing an access control timer.

Background

Under the 5G architecture, nodes on the radio access network (NG-RAN) side include two types, respectively:

a 5G base station node (gNB) providing NR (new air interface) user plane and control plane termination points with a terminal UE;

a 4G base station node (ng-eNB) accessible to the 5G core network provides E-UTRA (evolved universal terrestrial radio access) user plane and control plane termination points with the terminal. Although the node uses E-UTRA, the Core Network is connected with 5GC (5G Core Network ).

In 5G, RRC (Radio Resource Control) has three states, namely, RRC connected state, RRC idle state, and RRC inactive state (inactive state). When the terminal is in the RRC inactive state, the Radio Access Network (RAN) node releases the RRC connection of the terminal, but still maintains the connection of the NG2 and NG3 interfaces of the terminal.

A normalized Access Control (UAC) mechanism was introduced in 5G. And the NR-RAN broadcasts Access control parameters, and if Access control is required for each Access attempt, the terminal side finds out corresponding Access control parameters according to an Access category (Access category) corresponding to each Access attempt, a Public Land Mobile Network (PLMN) and Access identities (Access identities) to which the terminal side belongs, and enters Access prohibition judgment. If the judgment result is allowable, the terminal is allowed to initiate the access attempt; if the judgment result is not allowed, the terminal starts an access control timer (the duration is a number randomly generated according to a certain formula) corresponding to the access classification. And during the running period of the access control timer corresponding to the access classification, the access prohibition judgment result corresponding to the access classification is still prohibited.

However, there may be special cases where the access control timer needs to be stopped during the operation of the access control timer corresponding to a certain access class. There is no corresponding discussion or conclusion as to when and under what conditions the access control timer needs to be stopped in the current protocol.

and step 11, controlling the access control timer corresponding to the target access classification to stop under the condition that the terminal is changed in a preset way in the running process of the access control timer corresponding to the target access classification.

Preferably, the switching between the first type cell and the second type cell under the 5G architecture of the terminal includes at least one of the following switching:

Further, in the above embodiments of the present invention, the access control timer corresponding to the target access category may be run in an access stratum (i.e. AS layer) of the terminal, or may be run in a non-access stratum (i.e. NAS layer) of the terminal.

In the case that the access control timer corresponding to the target access category is running in the access stratum of the terminal, step 11 includes: and under the condition that the terminal is changed in a preset way, the access layer of the terminal controls the access control timer corresponding to the target access classification to stop.

In the case that the access control timer corresponding to the target access category is running in the non-access stratum of the terminal, step 11 includes: and under the condition that the terminal is changed in a preset way, the non-access layer of the terminal controls the access control timer corresponding to the target access classification to stop.

sending indication information to a non-access stratum of the terminal; or,

under the condition that the access attempt corresponding to the target access classification is triggered by a high layer, sending indication information to a non-access layer of the terminal; wherein the indication information is used for indicating that the forbidden state of the access attempt corresponding to the target access classification is eliminated or alleviated.

It should be noted that, in the above embodiment of the present invention, during the period that the state of the access attempt corresponding to the target access classification is the forbidden state, if the access attempt corresponding to the target access classification is initiated again, the result is directly the forbidden access; and when the forbidden state of the access attempt corresponding to the target access classification is eliminated or relieved, indicating that: if the access attempt corresponding to the target access classification is sent again, access prohibition judgment needs to be carried out again according to the access control parameters, and whether the target access classification can carry out the access attempt is judged.

If the access control timer corresponding to the target access classification is running in the non-access stratum of the terminal, the method further comprises:

Preferably, the access layer of the terminal sends the judgment result of the access barring judgment and the value information of the access control timer corresponding to the target access classification to the non-access layer of the terminal only when the judgment result of the access barring judgment is barring.

Further, in the above embodiment of the present invention, the method further includes:

Further, in the foregoing embodiment of the present invention, a value of the access control timer corresponding to the target access category is any one of the following values:

generating a random value according to a preset formula;

In order to more clearly describe the processing method of the access control timer provided in the embodiment of the present invention, the following description is made with reference to a plurality of examples:

example one: and when the following conditions occur in the access layer of the terminal, stopping the access control timer and passing through the non-access layer.

The access layer of the terminal performs access barring judgment on a target access classification (such as AC category 10), the judgment result is barring, the access layer of the terminal informs the non-access layer of the access barring judgment result, and starts a corresponding access control Timer1 for the target access classification.

When the terminal is subjected to one or more preset changes, the access stratum of the terminal stops Timer1 corresponding to the AC category 10 (if the Timer1 is still running), and the access attempt prohibition of the target access category is eliminated or relieved through the non-access stratum.

The preset variation comprises at least one of the following variations:

the PLMN to which the terminal belongs changes;

the terminal is synchronously reconfigured and the main cell is changed;

the terminal is synchronously reconfigured and the key is changed;

a terminal performs cross-Radio Access Technology (RAT) conversion; for example, the terminal switches to other radio access technology, RAT, camping, or the terminal switches to other RAT to operate as a master cell group or master cell.

Optionally, the access layer notifies the non-access layer only when the access attempt corresponding to the target access classification is triggered by the higher layer, and the prohibition of the access attempt corresponding to the target access classification is eliminated or alleviated.

Example two: only the terminal has a transition (which may be cell selection, reselection and/or handover) between the radio access technologies RATs, the terminal stops the access control timer and passes through the non-access stratum.

During the running of the Timer1 corresponding to the AC category 10, if the terminal performs the inter-RAT handover, the access stratum of the terminal stops the Timer1 corresponding to the AC category 10 and notifies the non-access stratum, and the access attempt barring corresponding to the AC category 10 is eliminated or alleviated.

For example, in an idle state or an inactive state, a camped cell is an NR cell, and after cell reselection occurs, the UE reselects to an E-UTRA cell of an EPC (4G core network), at this time, the NR access layer of the UE stops the timer1 corresponding to the AC category 10, and notifies the NAS layer, and the access attempt barring corresponding to the target access category is eliminated or mitigated. For another example, the terminal is in a connected state, the serving primary cell is an E-UTRA cell connected to a 5GC (5G core network), and then due to the movement of the terminal, the network side switches the terminal to the E-UTRA cell connected to an EPC (4G core network), at this time, the E-UTRA access layer of the terminal stops timer1 corresponding to the access category 10, and notifies the NAS layer, and the access attempt barring corresponding to the target access category is eliminated or mitigated.

Optionally, only when a handover occurs between the 5GC E-UTRA cell and the NR cell (the 5GC E-UTRA may be selected or reselected to the NR cell through the cell, or the NR cell may be selected or reselected to the 5GC E-UTRA cell through the cell, or the master cell group or the master cell may be changed from the 5GC E-UTRA to the NR cell through the handover, or the master cell group or the master cell may be changed from the NR cell to the 5GC E-UTRA through the handover), the access stratum of the UE stops the timer and notifies the NAS layer that the access attempt corresponding to the target access category is prohibited from being eliminated or mitigated. For other inter-RAT handover (e.g., UE reselects from 5GC E-UTRA cell to EPC E-UTRA cell or from NR cell to EPC E-UTRA cell), the UE access stratum only needs to stop the timer.

Example three: when the terminal performs a handover (which may be cell selection, reselection and/or handover) between the 5GC E-UTRA and the NR cell, the access control timer corresponding to the target access class continues or is inherited in the target cell after the handover.

During the operation of timer1 corresponding to the AC category 10, if the switch between the 5GC E-UTRA and the NR cell occurs (the 5GC E-UTRA cell selects or reselects to the NR cell, the NR cell selects or reselects to the 5GC E-UTRA cell, the master cell group or the master cell changes from the 5GC E-UTRA to the NR cell by a handover method, or the master cell group or the master cell changes from the NR cell to the 5GC E-UTRA by a handover method), the timer1 corresponding to the AC category 10 continues or is inherited in the target cell.

For example: the terminal is resided in the NR cell before, the cell is reselected to a 5GC E-UTRA cell due to the mobility of the terminal, at this time, if the timer1 corresponding to the AC category 10 is still running, the E-UTRA RRC layer inherits the access control timer running in the NR RRC layer, namely, the timer1 corresponding to the AC category 10 continues to run in the E-UTRA RRC layer until the time is out.

For the case that other inter-RAT transitions (cell selection, reselection and/or handover) occur, the access stratum of the UE stops timer1 corresponding to the AC category 10, and optionally, the access stratum of the UE notifies the NAS layer that the access attempt barring corresponding to the access category is eliminated or mitigated.

In other cases, the terminal does not need to perform special processing on the access control timer, for example, when cell reselection or handover occurs in the RAT, if there is an access control timer corresponding to a certain access category in operation, the UE does not need to process the access control timer.

Example four: for an idle state terminal and an inactive state terminal, an access layer of the terminal judges whether an access control timer corresponding to a certain access classification needs to be stopped or not according to conditions; and for the connected terminal, the terminal operates according to the indication of the network side.

If the UE is in the RRC idle state or the inactive state at this time, the terminal stops the access stratum of the UE from the timer1 corresponding to the AC category 10 (if still running) and notifies the NAS layer that the access attempt barring corresponding to the access category is eliminated or mitigated when the following occurs (which may be one or more):

the PLMN to which the terminal belongs changes;

If the terminal is in the connected state at this time, the network side judges whether the access control timer is continuously operated or stopped, and informs the result to the terminal. For example, the terminal is in a connected state, and the main serving cell is an NR cell. Due to the mobility, the terminal needs to be handed over from NR cell 1 to NR cell 2. The network side compares whether the access control parameters of the NR cell 1 and the NR cell 2 are consistent, if not, the network side issues an indication for indicating that the access layer of the terminal needs to stop the running access control timer (if any). The access stratum at the terminal side stops the running access control timer (if any) according to the network side indication.

Optionally, the access stratum of the terminal notifies the non-access stratum, and the access attempt prohibition corresponding to the access classification is eliminated or alleviated; or the access layer of the terminal directly performs access control judgment again according to the updated access control parameters, and notifies the access control judgment result (forbidden or allowed/forbidden to be relieved) to the non-access layer.

Example five: in the event of a change in access control parameters, either a cell switch across RATs occurs or the PLMN changes, the access control timer is stopped.

Regardless of the RRC state of the terminal, during the operation of the access control Timer (e.g., Timer1 corresponding to the access category 10), the access control parameter is changed (e.g., a new access control parameter is received through a system message or a new access control parameter is received through RRC dedicated signaling), and the access layer of the terminal stops the operating access control Timer (if any). Note: the access control parameter may be any access control parameter change, or may be an access control parameter change that defines an access category to which an access control timer that is running belongs).

Optionally, the access stratum of the terminal notifies the non-access stratum, and the access attempt prohibition corresponding to the access classification is eliminated or alleviated; or the access stratum of the UE directly performs access control judgment again according to the updated access control parameter, and notifies the non-access stratum of the access control judgment result (prohibition or permission/prohibition mitigation) according to the access control classification (such as AC category 10) corresponding to the running access control timer.

In addition, although the access control parameters are not changed, a cell switch across RATs occurs, such as when the camping cell is changed from NR to a cell of another RAT, or when the camping cell is changed from a 5GC E-UTRA cell to an NR cell, or when the operating primary cell is changed from a 5GC E-UTRA cell to an EPC E-UTRA cell, the access stratum of the terminal stops the running access control timer (if any). Optionally, the access stratum at the terminal side notifies the non-access stratum that the access attempt barring corresponding to the access category is removed or mitigated.

Optionally, the non-access stratum informs the access stratum of the PLMN change, although the access control parameters have not changed, at which point the access stratum stops the running access control timer (if any). Optionally, the access stratum at the terminal side notifies the non-access stratum that the access attempt barring corresponding to the access category is removed or mitigated.

Example six: for access attempts controlled by the non-access stratum, an access control timer is submitted to the non-access stratum, which handles the access control timer.

The access layer of the terminal carries out access prohibition judgment on a certain access classification (such as AC category 10), and the judgment result is prohibition; and the access layer of the terminal informs the non-access layer of the access prohibition judgment result and the value of the corresponding access control timer.

The value of the access Timer is generally a random number generated according to a certain formula, but if a Timer3 (T302 in the protocol) started by receiving a reject message sent by the network side is running, the value of the access control Timer fed back by the access stratum of the terminal at this time may be directly the current remaining value of the Timer3, or may be the maximum value of the current remaining value of the Timer3 and the random number generated according to a certain formula.

After receiving the access barring judgment result and the value of the corresponding access control Timer, the non-access layer marks the access attempt of the AC category 10 as barred, and simultaneously starts an access control Timer2 for the access attempt of the AC category 10. During the running of the Timer2, if the non-access stratum initiates an access attempt of the AC category 10 again, the result is directly forbidden access;

when the non-access stratum of the terminal changes PLMN or the state of the non-access stratum changes (e.g., the non-access stratum transitions from the registration state to another state (e.g., a de-registration state, a null state, etc.)), the non-access stratum stops the running access control timer (if any). If the subsequent non-access layer initiates the access attempt corresponding to the access control again, the access control judgment needs to be carried out again.

The above is only for access attempts controlled by the non-access stratum, for access attempts controlled by the access stratum (such as RNA update procedure), the access stratum of the terminal stops the access control timer (if running) corresponding to rnapdate when the following (which may be one or more) occurs:

when a PLMN change occurs;

when switching to other RAT to park or switching to other RAT to work as a master cell group or a master cell;

alternatively, the access control timer is running until it expires or the terminal switches to camping on another RAT or operates as a master cell group (or master cell), and the access control timer corresponding to the RNA update is stopped (if running).

In summary, in the above embodiments of the present invention, for the access control timer corresponding to the target access category in the operation process, when the terminal side has a preset change, the terminal does not need to wait for the access control timer to time out, and the terminal controls the access control timer corresponding to the target access category to stop, so that the forbidden state of the access mechanism determination result corresponding to the target access category is eliminated or alleviated, thereby improving the overall flow of the access control mechanism and avoiding the situation that the access control mechanism operates incorrectly.

step 21, sending stop instruction information to the terminal, where the stop instruction information is used to instruct the terminal to stop the access control timer corresponding to the target access category.

And in the running process of the access control timer corresponding to the target access classification, the network side equipment judges whether the access control timer continues running or stops running, and sends the result to the terminal. If the network side equipment determines that the access control timer continues to operate, no additional operation is needed; and if the network side equipment determines that the access control timer stops, sending stop indication information to the terminal.

And the access layer of the terminal stops the running access control timer according to the stop indication information of the network side equipment.
