Systems and methods discussed herein are directed to enabling users to remain in a first network billing system but access a second network for wireless communication network services. This occurs via an OTA update of a user's UE SIM, where the update changes the primary public land mobile network (PLMN) from the first network to the second network. Additionally, the network capabilities for the UE are cross-provisioned from the first network to the second network, where the first network provides a service or rate plan to the second network.

A method at a computing device within an Intelligent Transportation System (ITS), the method including: receiving a first message, the first message including at least tailoring information for a first ITS endpoint and intended journey details for the first ITS endpoint; storing all or a subset of data from the first message; obtaining a full certificate revocation list; creating a tailored certificate revocation list based on data in the first message and the full certificate revocation list, the tailored certificate revocation list containing certificates or identifiers of certificates for ITS endpoints that may be encountered by the first ITS endpoint when navigating a route provided in the intended journey details; and providing the tailored certificate revocation list to the first ITS endpoint.

A method for handling a service connection in a wireless communication system, including detecting, by a User Equipment (UE), a Mobility Management (MM) service state of the UE is set to ATTEMPTING TO UPDATE, receiving, by the UE, a valid Temporary Mobile Subscriber Identity (TMSI) in a TMSI reallocation procedure from a base station via a Radio Resource Control (RRC) connection, changing, by the UE, the MM service state to a NORMAL SERVICE state in response to the receiving a valid TMSI and the detecting a MM service state, and sending, by the UE, a paging response message to the base station in response to the changing the MM service state and a paging indication message received from the base station to establish the service connection, the paging indication message including the valid TMSI.

Techniques for designating non-native communication clients as the primary client for user equipment are discussed herein. A primary client can be the communication client designated to receive incoming communications for the user equipment. The user equipment may use the primary client to send, to a network device, a Session Initiation Protocol (SIP) instance to set primary client. The SIP instance may include a primary designator and a Universally Unique Identifier (UUID) associated with the client. The network device may store the information for the user equipment including the UUID and capability set. A second user equipment may poll the network device for the communications capabilities of the first user equipment before establishing a connection.

The invention concerns a method for establishing a bidirectional communication channel between a server and a secure element cooperating with a terminal in a cellular telecommunication network for exchanging data and commands, the method comprising: a—Sending a first attachment request signaling message from the terminal to the server, the first message comprising a MCC and a MNC of the server, and at least a part of a unique identifier of the secure element, the server being provisioned with the unique identifier; b—Sending from the server to the secure element, in at least a first signaling message: At least a command; A correlation identifier if further messages have to be sent from the secure element to the server; A first payload comprising data; c—Executing at the secure element the command.

Embodiments of the prevent disclosure provide a network access authentication method and device. The method includes: receiving an authentication request message sent by a first serving network, the authentication request message carrying a user equipment alias identifier generated by user equipment; determining whether a local user equipment alias identifier is asynchronous with the user equipment alias identifier generated by the user equipment; and when the determination result is positive, obtaining an encrypted International Mobile Subscriber Identification Number IMSI for performing network access authentication on the user equipment

Aspects of the subject disclosure may include, for example, a device that includes a processing system and a memory that stores executable instructions that, when executed by the processing system, facilitate performance of operations such as receiving an extensible authentication protocol (EAP) authentication message addressed to an EAP authentication server from a communication device; extracting information from the EAP authentication message; determining whether to reject a request in the EAP authentication message of the communication device based on the information extracted; and sending an EAP Failure message to the communication device after intercepting an authentication and key agreement message from the communication device based on the determining indicating that the request should be rejected. Other embodiments are disclosed.

Embodiments of the present invention disclose a method, a network device, and a base station for paging a narrowband terminal, where the method includes: determining a first paging message for paging a narrowband terminal; sending the first paging message including a radio capability of the narrowband terminal to a base station, so that the base station obtains the radio capability of the narrowband terminal and transmits a second paging message according to the radio capability of the narrowband terminal. In the embodiments of the present invention, after it is determined that a first paging message is used to page a narrowband terminal, because the radio capability of the narrowband terminal is added in the first paging message, a base station is allowed to transmit a second paging message according to the radio capability of the narrowband terminal.

A method of operating a user equipment (“UE”) to handle an internet protocol multimedia subsystem (“IMS”) emergency call can include sending a session initiation protocol (“SIP”) REGISTER request relating to an emergency registration to a proxy call session control function (“P-CSCF”) of an IMS network. The method can further include, responsive to sending the SIP REGISTER request, receiving a response from the P-CSCF. The method can further include, responsive to receiving the response, performing an action based on the response.

A method of operating a policy and charging rules function (“PCRF”) node to handle an internet protocol multimedia subsystem (“IMS”) emergency call can include receiving an identity request from a proxy call session control function (“P-CSCF”) of an IMS network. The identity request can include an internet protocol (“IP”) address for a user equipment (“UE”). The method can further include, responsive to receiving the identity request, determining one or more identifiers of the UE based on the IP address. The one or more identifiers are separate from the IP address. The method can further include, responsive to determining the one or more identifiers, transmitting an indication of the one or more identifiers of the UE to the P-CSCF.
