Provided are a method of performing cell reselection and a device supporting the method. According to one embodiment of the present disclosure, the method includes: starting data transmission or data reception while the UE is in radio resource control (RRC) idle state or RRC inactive state; applying an offset value to a serving cell for cell reselection; performing cell reselection based on the applied offset value, during the data transmission or data reception; and stopping applying the offset value to the serving cell, when the data transmission or data reception is succeeded.

A network entity for a mobile telecommunications system, including circuitry configured to perform an admission control of a received connection request to the mobile telecommunications system, wherein the admission control is performed based on a plurality of admission control layers.

The disclosure relates to a 5G or 6G communication system for supporting a higher data transmission rate. Embodiments herein provide a method of an access and mobility management function (AMF). The method includes monitoring whether a user equipment (UE) registered to a network slice establishes a protocol data unit (PDU) session using the network slice for a time, determining that the UE does not establish the PDU session in the time based on an expiration of a timer and deregistering the UE for the network slice.

The invention relates to a method for allocating radio resources to a transmitting terminal for performing direct communication transmission over a direct link connection. The transmitting terminal receives a system information broadcast from the base station, which comprises information on a temporary transmission radio resource pool, indicating radio resources for performing a direct communication transmission, and comprises configuration information on the resource pool to limit the amount of time that the temporary radio resource pool is usable by the transmitting terminal.

There are provided measures for enforcement of maximum number of admitted terminals per network slice. Such measures exemplarily comprise receiving a packet data connection related request concerning a network slice being configured with a maximum number of terminals to be admitted to said network slice, maintaining a counter indicative of a number of terminals admitted to said network slice based on said packet data connection related request, and transmitting a response to said packet data connection related request.

Techniques are described to provide traffic steering and policy combining in a mobile network. In one example, a method includes combining, by a policy function of a network, a user equipment (UE) access policy comprising UE access rules obtained from a UE with a network-based access policy associated with the network to generate a combined access policy, the combined access policy comprising combined access rules; communicating the combined access rules to the UE via a message, wherein the message comprises an indication that indicates that the UE is not allowed to override the combined access rules with the UE access rules; and communicating the combined access rules to a user plane function handling traffic for the UE.

Disclosed are an access rejection method, apparatus and system, where the access rejection method includes: a first base station receives an access request from a terminal; and the first base station sends an access rejection message to the terminal; where the access rejection message at least carries: a check value generated based on a key of the terminal and at least part of contents of the access rejection message. And further disclosed are related computer storage media and processors.
