Abstract: A method and system for accessing a network slice specific random-access channel resources pool at a user equipment is presented. The user equipment is in connected-mode with an inactive state and triggers a random-access procedure for resumption of a radio resource control connection. Therefore, at least one slice identifier from a non-access stratum layer to an access stratum layer is provided and at least one network slice to use for the radio resource control connection is determined based on the provided at least one slice identifier.

Abstract: Techniques for preventing denial of call transfer are provided. For example, a method, comprises: indicating, in an apparatus, that a call pull is initiated; categorizing, in the apparatus, an access attempt occurred for the call pull as a mobile-terminated access attempt; and making, in the apparatus, the access attempt to a network by transmitting a message to enable a process for the call pull, wherein the message includes a cause value set according to the categorization of the access attempt. The method may be performed by a user equipment (UE).

Abstract: A method, apparatus, and computer program product for detecting and switching between locally available PLMNs accessible to a user equipment based on a Preferred PLMN List and a Network Slice Aware PLMN Exceptions List configured by a HPLMN. The user equipment connects to a preferred VPLMN. The user equipment determines that a particular network function is not supported by the connected preferred VPLMN. The user equipment determines that another VPLMN is required to support the particular network function. The user equipment then switches to a non-preferred VPLMN which supports the particular network function. Once the particular network function is no longer necessary for the user equipment to perform a required task, the user equipment switches back a preferred VPLMN

Abstract: A method, apparatus and computer program product are provided herein to provide a Protocol Data Unit (PDU) session priority parameter. For example, a method is provided that comprises identifying a need in a user equipment (UE) for establishing a new protocol data unit PDU session. The method also includes evaluating whether to establish a new PDU session and determining whether to establish a new PDU session based on a PDU session priority parameter when a maximum number of PDU sessions the UE can establish in the network is reached.

Abstract: A method includes transmitting, by a user equipment (UE), a first message to a network node, the first message including a request for access to a first network according to a non-access stratum (NAS) protocol. The UE receives a second message from the network node, the second message including an indication of no network slice being available to service access to the first network requested by the UE. The UE disables a capability to access networks using the NAS protocol based upon the receiving the second message, stores an identity of the first network, and after storing, exploits the stored identity of the first network, by the UE, during a network selection process.
