  • Publication number: 20210250846
    Abstract: A method performed by a wireless device (130). The method is for handling access to a cell (120) served by a network node (110). The wireless device (130) and the network node (110) operate in a wireless communications network (100). The wireless device (130) obtains (201) a set of indications broadcasted by the network node (110) in the cell (120). The set of indications indicate that access to the cell (120) is allowed only to wireless devices simultaneously supporting at least two features of a plurality of features comprising a first feature and a second feature. The wireless device (130) then determines (202) whether or not access to the cell (120) is barred to the wireless device (130) based on the obtained set of indications.

  • Publication number: 20210250820
    Abstract: A method for a handover procedure comprises establishing a connection with a source network node of a first core network; receiving a radio resource control (RRC) message including an information element, wherein the information element indicates a second core network associated with a target network node; applying security parameters based on the second core network indicated in the information element; and performing a handover toward the target network node using the applied security parameters. The method provides an indication in RRC connection reconfiguration procedure to indicate the UE the core network of the target network node, so that the UE may recognize that this is an inter-system handover and apply corresponding security parameters for performing the handover without additional signaling.

  • Publication number: 20210212145
    Abstract: A wireless device (14) transmits, to a radio network node (12), a radio resource control (RRC) connection request (18) that requests the establishment, re-establishment, or resumption of an RRC connection (16). The RRC connection request (18) indicates a type of core network to which the wireless device (14)selects to connect. The wireless device (14) in some embodiments receives a response to the RRC connection request (18), based on the type of core network to which the wireless device (14) selects to connect. For example, the wireless device (14) may receive the response using a protocol stack determined based on the type of core network to which the wireless device (14) selects to connect.

  • Publication number: 20210153022
    Abstract: A network node is configured for use in a wireless communication network. The network node is configured to acquire radio access capability information of a wireless device. The radio access capability information of the wireless device indicates radio access capabilities of the wireless device. The network node is configured to determine if the wireless communication network received the radio access capability information of the wireless device before access stratum security was activated for the wireless device. If the wireless communication network received the radio access capability information of the wireless device before access stratum security was activated for the wireless device according to that determination, the network node is configured to re-acquire the radio access capability information of the wireless device after access stratum security is activated for the wireless device.

  • Patent number: 10993199
    Abstract: A method by a UE is provided to handle communication in a network, wherein the UE is capable of receiving a registration area configuration including area identifiers associated with different cells of different RATs. The UE receives, from a network node, a first mobile identifier and a second mobile identifier in a message during a transition of states of the UE, wherein the first mobile identifier is of a first length and the second mobile identifier is of a second length different than the first length. Furthermore, the UE uses the first mobile identifier to resume to a first network node of a first RAT in the registration area configuration of the UE, and the second mobile identifier to resume to a second network node of a second RAT in the registration area configuration of the UE.

  • Publication number: 20210044964
    Abstract: According to an embodiment, a method performed by a wireless device includes transmitting, to a network node, a message requesting a grant of resources for transmitting a first message and, in response, receiving a grant message granting the resources. The method further includes determining, based at least in part on the grant message, whether a length of a temporary device identifier of the wireless device exceeds a limit that the network node is capable of receiving in the first message. When the temporary device identifier does not exceed the limit, the method includes transmitting the temporary device identifier to the network node in the first message. When the temporary device identifier exceeds the limit, the method includes transmitting a first portion of the temporary device identifier in the first message and transmitting a second portion of the temporary identifier in a second message to the network node.

  • Patent number: 10805785
    Abstract: Methods, a core network node (104A) and a node (102A) in a radio access network, RAN, (102), for enabling emergency services for wireless devices in the RAN. The core network node (104A) sends (2:1), to the RAN node (102A), information about one or more Access and Mobility Management Functions, AMFs, that support emergency services, to avoid an emergency fallback procedure for wireless devices in the RAN. The RAN node (102A) then selects (2:2) an AMF (104B) that supports emergency services for a wireless device (100) in the RAN, based on the received information. Thereby, the wireless device will have immediate access to emergency services and no delaying emergency fallback procedure is performed which could be critical in an emergency situation.
