This application provides a method, apparatus, electronic device, medium, and product for voice conversation calls. The method includes: an MCX proxy server determining a target group from multiple pre-configured groups in an Interworking Function (IWF) whose first attribution information is information of interest; receiving a call request initiated by a first user terminal; and establishing a conversational call channel between the IWF and the Mission-Critical Service (MCX) based on the call request. Then, it receives voice information sent by the first user terminal and sends the voice information to the target group through the established conversational call channel, so that multiple second user terminals in the target group receive the voice information. This method, through the MCX proxy server, requires only one conversation between the IWF and the MCX to send voice information to multiple terminals, reducing bandwidth and conversation resource consumption.

Apparatuses, methods, and systems are disclosed for modifying a first data connection during the establishment of a second data connection. One apparatus includes a processor and a transceiver that receives a first request via a first data connection with a first mobile network, the first request containing a first set of parameters for establishing a second data connection with an interworking function in a second mobile network. Via the transceiver, the processor sends a second request to modify the first data connection, the second request containing a second set of parameters for modifying the first data connection to support the data traffic of the second data connection and transmits the data traffic of the second data connection through the modified first data connection.

An apparatus establishes a secure tunnel within a non-3GPP network to connect to a 5G core network (5GCN) via a non-3GPP Interworking Function (N3IWF) service of the 5GCN. The apparatus lacks subscriber identity module (SIM) capability and eSIM capability. The non-3GPP network connects to the 5GCN using a backhaul network that lacks a radio access network (RAN). The apparatus includes a connectivity stack that configures the apparatus to establish the secure tunnel. The connectivity stack includes a control plane layer and a user plane layer. The apparatus sends a registration request to the 5GCN via the established secure tunnel. The apparatus performs a security handshake with the 5GCN via the N3IWF service. The security handshake includes an exchange of security parameters between the apparatus and the N3IWF service. The apparatus receives a message indicating that registration of the apparatus with the 5GCN over the non-3GPP network is complete.
