Abstract: An IP Multimedia Subsystem (IMS) call establishing method is provided. The IMS call establishing method is applied to an electronic device which supports IMS service. The IMS call establishing method includes the steps of establishing a network connection between the electronic device and a client device; when the client device dials an IMS call, the electronic device obtains call information of the IMS call through the network connection; and the electronic device establishes the IMS call based on the call information of the IMS call.

Abstract: A method for updating access technology information for a Multi-Access (MA) Protocol Data Unit (PDU) session is provided. A User Equipment (UE) establishes an MA PDU session with a mobile communication network over a 3rd Generation Partnership Project (3GPP) access and a non-3GPP access. The UE provides first access technology information indicating to the mobile communication network that the UE is using one of the 3GPP access and the non-3GPP access to get an Internet Protocol (IP) connectivity. The UE detects that the IP connectivity over the one of the 3GPP access and the non-3GPP access is deactivated. The UE provides second access technology information indicating to the mobile communication network that the UE is using the other of the 3GPP access and the non-3GPP access to get another IP connectivity.

Abstract: A method for expedited tunnel establishment with a non-Third Generation Partnership Project (3GPP) interworking gateway to access a 3GPP network is provided. A User Equipment (UE) initiates establishment of an Internet Protocol secure (IPsec) tunnel with a first non-3GPP interworking gateway associated with the 3GPP network. The UE probes availability of a second non-3GPP interworking gateway associated with the 3GPP network before the IPsec tunnel with the first non-3GPP interworking gateway is established successfully. The UE initiates establishment of an IPsec tunnel with the second non-3GPP interworking gateway in response to failing to establish the IPsec tunnel with the first non-3GPP interworking gateway and the second non-3GPP interworking gateway being available. The UE accesses the 3GPP network over the IPsec tunnel with the second non-3GPP interworking gateway.
