Detailed Description
The technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application. It should be understood that the specific embodiments described herein are merely illustrative of the present application and are not intended to limit the present application.
Unified Access Control (UAC) is a mechanism introduced in a 5G system to control a terminal to access a network, and aims to alleviate network congestion at a base station side. The mechanism supports all services, and is applicable to all states of the terminal: an idle state, a deactivated state, and a connected state. In the process of performing unified access control, the base station broadcasts access control Information in a System Information Block (SIB), which is a list of access parameters associated with an access identity and an access category, i.e. a barring parameter set consisting of a barring factor and a barring time. The terminal determines whether to allow access for the same access request as the access category based on the barring parameter sets and the terminal configuration. In the process of unified access control, the non-access layer is responsible for mapping different access requests and different priority users into an access category and one or more access identifiers, and the access layer determines whether to allow access according to the access category, the access identifiers and a blocking parameter set broadcasted by a network.
For the current requirements of 3GPP TS24.501 regarding the unified access control section, the general mechanism when a terminal processes a certain network access request (e.g. PDU session creation is initiated by the upper layer in idle mode) is shown in fig. 1:
11. the network access request is sent.
It should be noted that, after receiving the network access request sent by the upper layer application, the NAS layer determines a request type corresponding to the network access request from the configuration information of the terminal configuration and sets one or more request identifiers according to a mapping relationship between different access requests and terminal configurations.
It should be noted that, after receiving the network access request, the NAS layer sends the network access request to the AS layer.
It should be further noted that, the network access request sent by the NAS to the AS layer may specifically be a NAS signaling link establishment request.
It should be further noted that the NAS signaling link establishment request may be signaling generated by the NAS layer after the NAS layer receives the network access request.
It should be noted that the NAS signaling link establishment request sent by the NAS layer to the AS layer carries the request category and the request identifier.
After the AS layer receives the NAS signaling connection establishment request sent by the NAS layer, the AS layer can determine whether the network access request can be sent to the network side.
The AS layer may perform access control checks on the network access request in the following order, AS required by the 3GPP TS38.311 for the unified access control section.
12. And sending a blocking parameter, wherein the blocking parameter comprises blocking time.
In the embodiment of the application, the network side may send the blocking parameter to the AS layer before the NAS layer sends the network access request to the AS layer; the network side may send the barring parameter to the AS layer after the NAS layer sends the first network access request to the AS layer, which may be specifically determined according to an actual situation, and this is not limited in this embodiment of the present application.
It should be noted that the blocking parameter further includes a set of blocking factors.
13. It is determined that the network access request is barred.
The AS layer firstly checks the running state of a second timer in the AS layer, and if the running state of the second timer is running, the network access request is determined to be forbidden; if the running state of the second timer is not running, the AS layer checks the request type and the request identification sent by the NAS layer according to the access control information in the system message SIB1 sent by the network side. Each request class has a corresponding set of blocking parameters. The AS layer firstly checks the request identifications, if the blocking parameter corresponding to one of the request identifications is 0, the access is allowed, namely the network access request can be sent to the network side, if the blocking parameters are all 1, the blocking check of the request category is carried out, if the random number generated by the AS layer is smaller than the blocking factor in the blocking parameter set, the access is allowed, namely the network access request can be sent to the network side. Otherwise, the network access request is determined to be forbidden.
14. Transmitting the network access request prohibited information.
The AS layer sends network access request forbidden information to the upper layer application through the NAS layer.
15. And determining the running time of the second timer according to the blocking time, and starting the second timer.
If the network access request is forbidden, the AS informs the NAS layer network that the network access request is forbidden, and starts a second timer, wherein the running time of the second timer is (0.7+ 0.6) blocking time, the blocking time is a random number between 0 and 1, and the blocking time is the access forbidden time in the SIB 1.
During the time that the second timer is running, all access requests of the same request category as the network access request are barred.
16. A request for mitigation message is sent.
In the event that the second timer times out or otherwise stops, the AS sends a request for mitigation message to the NAS. The NAS layer forwards the request release message to an upper layer, and the upper layer application determines whether to continue initiating the network access request.
The network access request initiated by the terminal is judged in the NAS layer and the AS layer, and the fact that the network access request is forbidden due to the unified access control mechanism is determined, namely the AS starts a corresponding second timer of the access category, the terminal cannot perform the same access attempt within the period of time when the second timer runs, and the AS layer generates a release notice until the second timer runs overtime or stops running, and the terminal can send an RRC connection establishment request to the base station.
However, it is uncertain for the application layer when the user triggers the network access request, so even if the terminal receives the release notification, the terminal cannot immediately initiate the network access request, requesting to send an RRC connection establishment request to the base station. This presents a problem: when there is a network access request, do NAS layer and AS layer need to do unified access control check for the network access request? If the unified access control check needs to be performed, the access request may be prohibited again after being judged, and the access may be initiated again after the duration of a second timer, so that the success rate of establishing the RRC connection between the terminal and the base station is reduced, and the user experience is reduced. If the unified access control check is not needed, the original purpose of the unified access control mechanism is violated, and the network load of the base station side is increased, so that the network congestion is generated at the base station side.
The problems in the prior art can be solved by the following methods in the following embodiments.
An embodiment of the present application provides a network connection method, which is applied to a terminal, where the terminal includes a first timer, and fig. 2 is a first flowchart of the network connection method provided in the embodiment of the present application, and as shown in fig. 2, the network connection method may include:
s101, receiving a request release message transmitted by an AS layer by an NAS layer under the condition that the first network access request is determined to be forbidden and the request forbidden time length is up.

In the embodiment of the application, the request prohibition duration may be a duration preset in the terminal and used for not sending the first network access request to the network side; the request prohibition duration may also be a duration for which the network side broadcasts that the terminal is not allowed to send the first network access request to the network side; the request prohibition duration may also be a duration determined by the terminal according to the information broadcast by the network side, where the first network access request is not sent to the network side, and may specifically be determined according to an actual situation, which is not limited in this embodiment of the present application.
In the embodiment of the application, the terminal may generate the first network access request corresponding to the service access request under the condition that the service access request is triggered.
In an embodiment of the present application, the first network access request includes a data transmission channel allocation request or a voice call initiation request. Specifically, the Data transmission channel allocation request is a user plane resource request received by the terminal from a Data Plane (DP) and used for establishing an existing Packet Data Unit (PDU) session; the voice call initiation request may be a Multimedia telephone service (MMTEL) voice call initiation request from an IP Multimedia System (IMS) received by the terminal.
In this embodiment of the present application, the AS layer further includes a second timer, and when the terminal determines that the first network access request is prohibited and the request prohibition duration reaches, before the NAS layer receives the request mitigation message transmitted by the AS layer, the terminal further performs the following operations: under the condition that the NAS layer receives the first network access request, the terminal acquires a request parameter of the first network access request from the first network access request and transmits the request parameter to the AS layer; after the terminal transmits the request parameter to the AS layer, the AS layer of the terminal determines whether to start a second timer according to the request parameter and the blocking parameter; and after the AS layer of the terminal determines whether to start the second timer according to the request parameter and the blocking parameter, the AS layer determines the request forbidding duration based on the blocking time under the condition that the AS layer determines to start the second timer, and forbids to send a second network access request to the network side within the request forbidding duration.
In an embodiment of the present application, the second network access request includes a data transmission channel allocation request or a voice telephone initiation request. Specifically, the Data transmission channel allocation request is a user plane resource request received by the terminal from a Data Plane (DP) and used for establishing an existing Packet Data Unit (PDU) session; the voice call initiation request may be a Multimedia telephone service (MMTEL) voice call initiation request from an IP Multimedia System (IMS) received by the terminal.
It should be noted that the first request type of the first network access request is the same as the second request type of the second network access request.
It should be noted that the first request category may be a request category for a user to initiate data actively, and may also be a multimedia voice telephone category, which may be specifically determined according to an actual situation, and this is not limited in this embodiment of the present application.
It should be further noted that the request category for the user to actively initiate data may specifically be category 3: a terminal initiates (MO) data type; the multimedia voice telephony category may be specifically category 4: MMTEL voice telephony category.
It should be noted that the blocking parameter is a parameter corresponding to the first request type and sent by the network side; the blocking parameter includes a blocking time.
It should be noted that the request parameter includes a first request category and a first request identifier.
It should be noted that the number of the first request identifier may be one, or may be multiple, and may be specifically determined according to an actual situation, which is not limited in this embodiment of the present application.
In this embodiment of the application, when the NAS layer receives a first network access request, the NAS layer determines, according to a mapping relationship between different access requests and terminal configurations, a first request type corresponding to the first network access request from configuration information of the terminal configuration, and sets one or more first request identifiers.
In the embodiment of the application, the NAS layer may directly transmit the request parameter to the AS layer when the NAS layer acquires the request parameter; the NAS layer may also generate an NAS signaling link establishment request under the condition that the request parameter is obtained, load the request parameter into the NAS signaling link establishment request, and then transmit the NAS signaling link establishment request carrying the request parameter to the AS layer.
In this embodiment of the present application, the process of determining, by the AS layer, whether to start the second timer according to the request parameter and the barring parameter includes: the AS layer determines the state of a second timer under the condition that the AS layer receives the request parameter; when the AS layer determines that the state of the second timer is a non-running state, the AS layer determines whether a parameter value of a first request identifier in the request parameters is a preset parameter value, and when the parameter value of the first request identifier is not the preset parameter value, the AS layer determines a blocking factor corresponding to the first access category from a blocking factor set in the blocking parameter, and generates a first random number, and when the first random data is greater than or equal to the blocking factor, the AS layer determines that the first network access request is forbidden, then the AS layer sends information that the first network access request is forbidden to the NAS layer, and simultaneously the AS layer starts the second timer.
It should be noted that the blocking factor set includes a plurality of blocking factors, and the AS layer may determine, in the blocking factor set, a blocking factor corresponding to the request type of the first network access request when the AS layer obtains the first request type.
It should be noted that, the manner of determining, by the AS layer, the blocking factor corresponding to the first request type in the blocking factor set may be: the AS layer obtains a corresponding relation between the request category and the blocking factor from the blocking factor set, and determines the blocking factor corresponding to the first request category according to the first request category and the corresponding relation between the request category and the blocking factor.
In this embodiment of the present application, in case that the first random data is smaller than the barring factor, then the access is allowed, and the AS layer sends the first network access request to the network side.
In the embodiment of the application, the first random number is a random number between 0 and 1.
In this embodiment of the present application, when the AS layer determines that the state of the second timer is the running state, the AS layer determines that the first network access request is prohibited, and the AS layer does not send the first network access request to the network side.
In this embodiment of the application, when the parameter value of the first request identifier is not a preset parameter value, it may be that none of the at least one parameter value of the at least one first request identifier is equal to the preset parameter value.
In this embodiment of the application, a parameter value of the first request identifier may be 0, and a parameter value of the first request identifier may be 1, which may be determined specifically according to an actual situation, and this is not limited in this embodiment of the application.
In the embodiment of the present application, the preset parameter value may be 0.
In this embodiment of the present application, if any one of at least one parameter value of at least one first request identifier is 0, the access is allowed, and the AS layer sends the first network access request to the network side, or sends the Radio Resource Control (RRC) connection establishment request to the network side.
In the embodiment of the present application, the request prohibition time period is specifically a running time period of the second timer. And the terminal starts to run the second timer after starting the second timer, and stops running the second timer when the running time of the second timer exceeds the request prohibition time.
In this embodiment of the application, the second timer may be a T390 timer, the second timer may also be a T302 timer, and the second timer may also be a T390 timer and a T302 timer, which may be determined specifically according to an actual situation, and this is not limited in this embodiment of the application.
S102, the NAS layer determines a first operation time length of the first timer according to the request relieving message and starts the first timer.
In this embodiment of the application, after the NAS of the terminal receives the request mitigation message transmitted by the AS layer, the NAS layer of the terminal may determine the first operation duration of the first timer according to the request mitigation message, and start the first timer.
In this embodiment of the present application, a process of determining, by an NAS layer of a terminal, a first operation duration of a first timer according to a request mitigation message includes: the NAS layer obtains blocking time and request forbidding duration from the request relieving message; after the NAS layer of the terminal obtains the blocking time and the request forbidding duration from the request relieving message, the NAS layer of the terminal determines that the first operation duration of the first timer is up according to the blocking time and the request forbidding duration.
It should be noted that the blocking time is a preset time corresponding to the first request type of the SIB1 information broadcasted by the network side.
In the embodiment of the application, the terminal can obtain the difference value between the blocking time and the request forbidding time, so that the first running time is obtained; the terminal may also obtain 1.3 times of the blocking time to obtain a product, and then obtain a difference between the product and the request prohibition time to obtain the first operation time, which may be specifically determined according to an actual situation, which is not limited in the embodiment of the present application.
In the embodiment of the application, the AS layer generates a second random number, determines 0.6 times of the second random number, adds 0.7 to the second random number to obtain a numerical sum, and multiplies the numerical sum by the blocking time to obtain the request prohibition time length.
The second random number is a random number between 0 and 1.
In this embodiment of the present application, in the first operation duration, when the NAS layer receives the second network access request, the AS layer does not perform the unified access control check on the second network access request, and may directly send the second network access request to the network side. In the process, if the time length of the first operation duration is too short, the first timer loses the existing meaning, and cannot achieve the effect of increasing the speed when the terminal sends the network access request to the network side, and if the time length of the first operation duration is too long, the requirement of unified access control cannot be met, so the time length of the first operation duration is an important parameter.
In the embodiment of the present application, the running duration of the second timer may be determined according to formula (1), that is, the request prohibition duration is obtained.
(0.7+0.6 random number) blocking time (1)
The formula (1) can obtain that if the value of the random number is 1, the maximum value of the request prohibition time length is 1.3 × barring time; if the value of the random number is 0, it can be obtained that the minimum value of the request prohibition time is 0.7 × blocking time, and the access request result of the second network access request is uncertain in the time period between 0.7 × blocking time and 1.3 × blocking time. Under the condition that no other reason causes the second timer to stop, if the random number is 1, the second network access request is forbidden in the period of 0 to 1.3 blocking time; if the random number is 0, the second network access request is prohibited in the time period from 0 to 0.7 × barring time, and in the time period from 0.7 × barring time to 1.3 × barring time, the second network access request can be sent to the network side under the condition that the second network access request is received. Thus, the first operating time period formula can be obtained as: 1.3 difference between blocking time and request inhibit duration.
In this embodiment, after the NAS layer of the terminal starts the first timer, the NAS layer of the terminal stops running the first timer when the first timer satisfies the condition for stopping running.
It should be noted that, after the NAS layer of the terminal stops running the first timer, when the terminal receives the second network access request again, the terminal needs to perform the unified access control check on the second network access request according to the second request type and the request identifier of the second network access request, and to determine whether to send the second network access request to the network side again.
In an embodiment of the application, the second request category is the same as the first request category of the first network access request.
It should be noted that the second network access request may be the same as the first network access request, that is, the second network access request is the first network access request; the second network access request may also be different from the first network access request, but the second request category is the same as the first request category.
In this embodiment of the application, the operation stop condition includes that the operation duration of the first timer is reached, or within the first operation duration of the first timer, the NAS layer receives the second network access request for a preset number of times.
In this embodiment of the present application, the preset number of times may be 1, that is, within the first operation duration of the first timer, when the NAS layer receives the second network access request, the NAS layer stops operating the first timer; the preset times can also be 2 times, that is, the NAS layer stops running the first timer when receiving the second network access request twice within the first running duration of the first timer; the preset times can also be multiple times, that is, within the first operation duration of the first timer, the NAS layer stops operating the first timer when receiving the second network access request multiple times; the specific details can be determined according to actual conditions, and the embodiment of the present application does not limit this.
In this embodiment of the application, the NAS layer stops running the process of the first timer when receiving the second network access request for the preset number of times within the first running time, where the NAS layer may be configured to transmit the second network access request to the AS layer when receiving the second network access request for the first time within the first running time, and the AS layer directly transmits the second network access request to the network side without performing unified access control check on the second network access request; if the NAS layer receives the second network access request again in the first running time, the NAS layer transmits the second network access request received by the NAS layer to the AS layer, and the AS layer directly transmits the newly received second network access request to the network side without performing unified access control check on the newly received second network access request; and until the number of the received second network access requests reaches a preset number.
It should be noted that, if the number of the second network access requests received by the NAS layer exceeds the preset number of times in the first operation time, the NAS layer sends the second network access requests exceeding the preset number of times to the AS layer, so that the AS layer performs unified access control check on the second network access requests exceeding the preset number of times.
