A wireless communication recovery method and a corresponding communication device are described. In the wireless communication recovery method, a connection failure of a radio access technology (RAT) is detected. Further, the detected connection failure is categorized based on a network level at which the connection failure has occurred. The RAT at the corresponding network level is then disabled for a time period based on the categorization of the connection failure and service in the RAT is recovered based on thresholds for the categorized failure levels.

Examples described herein relate to managing communications on a first subscription and a second subscription of a multi-Subscriber Identity Module (SIM) wireless communication device via a Radio Frequency (RF) resource, including, but not limited to, tuning the RF resource away from the second subscription to the first subscription, detecting a network-set activation state of a secondary cell associated with the first subscription, and adjusting the activation state of the secondary cell based on the network-set activation state.

Systems and methods are provided to support hypernumber portability for a hypernumber number corresponding to an electronic device. The electronic device may include an installed application to facilitate hypernumber portability. To this end, when the electronic devices connects to a wireless network, the electronic device may request a vehicle identification. If the wireless network is a vehicle-based network, the electronic device may receive the vehicle identification from an on-board node. When the received vehicle identification indicates that the electronic device has changed locations, the electronic device may communicate with a hypernumber database and/or a hypernumber server to update a dynamic phonebook. As a result, as the electronic device traverses a transport network, the dynamic phonebook may maintain updated location and call routing information for the electronic device.

Apparatuses and methods in a communication system are provided. A first radio resource connection, RRC, with a Radio Access Network, RAN, node is established (502) by a device, the connection having a first Radio Network Temporary Identifier and being associated with a first subscription identity. An RRC setup procedure for establishing a second RRC is performed (504), the connection being associated with a second subscription identity. During or after the RRC setup it is indicated to the RAN node that the device has an existing radio resource connection with the node. A second Radio Network Temporary Identifier associated with the second radio resource connection and an additional Radio Network Temporary Identifier common to the first and second radio resource connections are received (506) and the common Identifier is used (508) for communication with the RAN node.

Apparatuses, methods, and systems are disclosed for determining mobile network policy freshness. One method includes accessing a first policy associated with a first mobile network, a first policy identifier, and a freshness parameter. The method includes determining, based on the freshness parameter, whether the first policy is fresh. The method includes transmitting a registration message to a second mobile network. The registration message includes the first policy identifier in response to determining that the first policy is not fresh.

A method of a network function (NF) entity performing communication in a wireless communication system includes: in case that a first registration request of a user equipment (UE) for a slice is received at an access and mobility function (AMF) entity through a first network, receiving a first slice availability request message for the slice from the AMF entity; determining whether the slice is available for the UE, based on a network slice policy; and transmitting, to the AMF entity, a response message including information regarding slice availability of the UE according to the first registration request, wherein in case that a second registration request of the UE for the slice is received at the AMF entity through a second network, slice availability of the UE according to the second registration request is determined based on at least one of the network slice policy or the information regarding the slice availability of the UE according to the first registration request.

This disclosure handles a registration procedure in a UE supporting registration to 5GC via untrusted non-3GPP access network and 3GPP access network. More specifically this disclosure defines a UE behavior when a registration procedure is not successful to 5GC via first access network type (e.g. untrusted non-3GPP network access) after transmitting maximum number of registration request message via the first access network type to the 5GC and the UE is registered to 5GC via other access network type (e.g. 3GPP access network (NG-RAN)).

Methods and apparatus for receiving downlink data packets over Non-Third Generation Partnership Project (N3GPP) access. A User Equipment (UE) is configured to manage the triggering of Service Request procedures for receiving N3GPP Mobile Terminating (MT) packets in a coverage area of N3GPP access from a 5th Generation (5G) network. A Service Request procedure is triggered by the UE if the UE detects that the UE is in the coverage area of N3GPP access and that the UE is in 5th Generation Mobility Management (5GMM)-IDLE mode over N3GPP access and the back-off timer has expired. The detection is based on the UE determining that an access stratum connection is established between the UE and the 5G network over N3GPP access.

The present disclosure relates to a communication method and system for converging a 5th-Generation (5G) communication system for supporting higher data rates beyond a 4th-Generation (4G) system with a technology for Internet of Things (IoT). The present disclosure may be applied to intelligent services based on the 5G communication technology and the IoT-related technology, such as smart home, smart building, smart city, smart car, connected car, health care, digital education, smart retail, security and safety services. Embodiments herein provide a method for performing a routing ID (RID) update in user equipment (UE) in a wireless communication network.

Systems and methods for providing at least one electronic indication of network benefit of a telecommunication network include a first telecom network and a user device. The user device includes sim circuitry. The user device is structured to connect to the first telecom network and a secondary telecom network, receive at least one first device signal associated with the first telecom network and at least one secondary device signal associated with the secondary telecom network, determine one or more signal factors based on the at least one first device signal and the at least one secondary device signal, generate one or more network scores in response to the one or more signal factors determined, and based on the one or more network scores, provide at least one electronic indication of network benefit of the first telecom network and the secondary telecom network.
