Abstract
A method performed by a user equipment, UE, is disclosed. The method comprises determining (402) in response to an event (401) that triggers the UE to perform an access request to a radio access network, RAN, an access category to apply. The UE performs a barring check (403), applying the access category. Upon determining that access is not barred based on the access category, the UE sends (405) the access request to a network node in the RAN, the access request including the access category. The network node decides whether to accept or reject the access request based on the access category.
Claims25
A method performed by a user equipment (UE), the method comprising:
- determining, in response to an event that triggers the UE to perform an access request to a radio access network (RAN) an access category to apply, wherein prior to determining the access category to apply, the method comprising receiving system information broadcast by a network node in the RAN, wherein the received system information comprises an indication of a code-length to use for the access category;
- performing a barring check, applying the access category based at least on the code-length;
- and
- upon determining that access is not barred based on the access category, sending the access request to the network node in the RAN, the access request including the access category, wherein the network node decides whether to accept or reject the access request based on the access category and a network slice that the UE wants to access, wherein the network slice represents a virtual network.
A method performed by a network node in a radio access network (RAN), the method comprising:
- broadcasting system information that comprises an indication of a code-length to use for an access category;
- receiving an access request from a user equipment (UE) the access request including the access category, wherein the access request is triggered by an event and access is determined by the UE to not be barred based on the access category, wherein the access category is associated with the code-length of which the UE receives the indication, from the network node;
- and
- deciding whether to accept or reject the access request based on the access category and a network slice that the UE wants to access, wherein the network slice represents a virtual network.
A user equipment (UE), comprising:
- processing circuitry configured to:
- determine, in response to an event that triggers the UE to perform an access request to a radio access network (RAN) an access category to apply, wherein, the processing circuitry is further configured to, prior to determining the access category to apply, receive system information broadcast by a network node in the RAN, wherein the received system information comprises an indication of a code-length to use for the access category;
- perform a barring check, applying the access category based at least on the code-length;
- and
- upon determining that access is not barred based on the access category, send the access request to the network node in the RAN, the access request including the access category, wherein the network node decides whether to accept or reject the access request based on the access category and a network slice that the UE wants to access, wherein the network slice represents a virtual network.
A network node in a radio access network (RAN), the network node comprising:
- processing circuitry configured to:
- broadcast system information that comprises an indication of a code-length to use for an access category;
- receive an access request from a user equipment (UE) the access request including the access category, wherein the access request is triggered by an event and access is determined by the UE to not be barred based on the access category, wherein the access category is associated with the code-length of which the UE receives the indication, from the network node;
- and
- decide whether to accept or reject the access request based on the access category and a network slice that the UE wants to access, wherein the network slice represents a virtual network.
