A wireless communication network serves a wireless User Equipment (UE). The wireless UE exchanges user data over a data session of a Dynamic Network Name (DNN) while exchanging other user data over other data sessions of other DNNs. An Access and Mobility Management Function (AMF) receives a DNN message for the wireless UE and the DNN and responsively transfers a reattach message for the data session of the DNN to the wireless UE. The wireless UE receives the reattach message and responsively terminates the data session of the DNN and transfers a session message for the DNN to the AMF. The AMF receives the session message for the DNN and the wireless UE and responsively establishes a new data session for the DNN. The wireless UE exchanges new user data over the new data session of the DNN while exchanging additional user data over the other data sessions of the other DNNs.

Wireless communication service delivery using multiple data Network Names (DNNs)

A wireless communication network serves a wireless User Equipment (UE) over multiple Data Network Names (DNNs). The wireless communication network comprises network circuitry and a Radio Access Network (RAN). The network circuitry executes a Unified Data Management (UDM), a Session Management Function (SMF), and an Access and Mobility Management Function (AMF). The UDM detects a DNN reattach condition for the wireless UE and transfers a DNN reattach message for the UE to the SMF. The SMF receives the DNN reattach message and responsively transfers the DNN reattach message to the AMF. The AMF receives the DNN reattach message for the wireless UE and responsively transfers an N2 Packet Data Unit (PDU) session reattach message for the wireless UE to the RAN. The AMF receives an N2 PDU session request from the RAN for the wireless UE and responsively selects a new SMF for the PDU session.

A Dual Tone Multi Frequency (DTMF) circuit for relaying DTMF digits includes a communication interface, a storage system configured to store a sampling window size, a DTMF test sequence, a returned DTMF sequence, and one or more DTMF digits, with the one or more DTMF digits to be transferred to a second DTMF circuit by the DTMF circuit, and a processing system. The processing system receives the one or more DTMF digits via the communication interface and an input sampling window, generates the DTMF test sequence and transmits the DTMF test sequence to the second DTMF circuit, compares the DTMF test sequence to a returned DTMF sequence received back from the second DTMF circuit, and if the returned DTMF sequence is not the same as the DTMF test sequence, adjusts the sampling window size of the input sampling window.

Systems, methods, and software are described herein for operating a RTP server including receiving a session request from a user communication device indicating the user communication device has packet format switching capability, transferring an acknowledgement to the user communication device wherein the acknowledgement comprises at least a header-free packet string length, transferring a RTP stream using bundled packet format, transferring a packet format switch triggering event, and transferring the RTP stream using header-free packet format for at least as long as the header-free packet string length.
