DETAILED DESCRIPTION

The technical schemes in the embodiments of the present disclosure will now be described in conjunction with the accompanying drawings in the embodiments of the present disclosure, and it will be apparent that the described embodiments are merely parts of the embodiments of the disclosure, and are not all embodiments. All other embodiments obtained based on the embodiments in the present disclosure by those of ordinary skill in the art without making creative work are within the scope of the present disclosure.

A 5G-NR network may include a UE, and an access network and a core network located at a network side. An interface between the UE and the access network is an air interface. A protocol stack of the air interface may have two parts including a non-access stratum (NAS) and an access stratum (AS) . When establishing communication services between the UE and the network side, it needs to perform an access control, in order to determine whether a service request can be initiated, and avoid overload problems at the network side (including the access network and the core network) .

Referring to FIG. 1, a flow chart of an embodiment of an access control method of the present disclosure is depicted. The method may be applicable to a new radio system of the fifth generation mobile communication technology (5G-NR system) . The method may be the one based on the UE side, and may include the following blocks.

At block S101: the UE may be in a connected state or an inactive state, and whether there is a trigger event may be detected; wherein the trigger event is an access stratum trigger event or a non-access stratum trigger event.

More specifically, when the UE is in the connected state or the inactive state, the access stratum trigger event may be selected from a group including but not limit to:an event that the UE tries to set up a new data radio bearer or a signaling radio bearer, an event that the UE tries to modify an attribute of an existing radio bearer, an event that the UE tries to remap a quality of service (QoS) flow from one radio bearer to another radio bearer, an event that the UE tries to remap the QoS flow from a default radio bearer to a specific radio bearer, an event that the UE tries to delete the existing data or signaling radio bearer, an event that the UE tries to set up the new data radio bearer to transmit data, an event that the UE tries to perform a type conversion on the data radio bearer, and an event that the UE tries the UE trying to activate/deactivate a packet duplication and transmission functionality. When the UE is in the inactive state, the access stratum trigger event may also be selected from a group including: an event that the UE in the inactive state tries to transmit the data, and an event that the UE in the inactive state tries to initiate a notification area update procedure. When the UE is in the connected state or the inactive state, the non-access stratum trigger event may include but not limit to: requesting to start a voice, a video or a session initial protocol (SIP) call; sending a mobile originated short messaging service (SMS) ; establishing a new protocol data unit (PDU) session; modifying an existing PDU session; releasing the PDU session; re-establishing a user plane for the existing PDU session; or establishing a new emergency PDU session.

At block S102: when the trigger event is detected, the trigger event may be mapped to an access category, and the access stratum or the non-access stratum may make an access control decision on the access category.

More specifically, in one embodiment, before the block S102, the method may further include: pre-receiving the mapping rule. The block S102 may include: invoking the mapping rule, and in turn acquiring the access category corresponding to the trigger event. The mapping rule may be sent to the UE via a system broadcast message or a radio resource control (RRC) signaling of a base station.

The access category in the mapping rule may be determined by a trigger event type and/or a parameter of the UE. The parameter of the UE may be selected from a group including but not limit to: a flow identifier (also called as QFI below) of the QoS of data flow, a five-tuple (also called as 5QI below) of the data flow, an access class of the UE, a roaming status of the UE, an operating system identifier (OS ID) configured to trigger data access, or an operating system application identifier (OS AP ID) configured to trigger the data access.

In one embodiment, the trigger events of the UE may be divided into a plurality of access categories, for example, the trigger events of the UE may be divided into 12, 14, 16 access categories or the like. One access category may correspond to one or more trigger event, and the present disclosure may not be limited thereto. When the UE needs to initiate the service request, the UE may first need to check whether the access category that the UE itself belongs to is barred by a cell to be accessed. If the access category that the UE itself belongs to is barred by the cell to be accessed, the UE cannot initiate the service request. Otherwise, the UE may initiate the service request.

In one application scenario, the access category in the mapping rule may be determined by the trigger event type, as shown in Table 1 provided below. Different trigger event types correspond to different access categories. Certainly, in another embodiment, two or more trigger event types may correspond to the same access category, and the present disclosure may not be limited thereto.

Table 1 Mapping rule diagram

In another application scenario, as shown in FIG. 2 provided below, the access category in the mapping rule may be determined by both the trigger event type and the parameter of the UE. In this way, an operator may control an access of a specific application or a service type, as shown in FIG. 2 provided below. Although the rigger event types are the same, however, different data services establishing requests may be treated under a same access category, or may also be treated under different access categories.
