Solutions for providing proxy node (e.g., proxy-call session control function (P-CSCF)) selection by traffic type include: receiving, by a network node (e.g., a packet gateway (PGW)), from a network device (e.g., a user equipment (UE) or internet of things (IoT) device), a first message indicating a request for identification of a proxy node; receiving, by the network node, from the network device, an indication of a first data traffic type; based on at least the indication of the first data traffic type, selecting, by the network node, a first proxy node over a second proxy node to identify to the network device; and transmitting an identification of the first proxy node to the network device. Examples support network slicing and improve wireless priority service (WPS) and enhanced 911 (SECOND DATA TRAFFICE911).

Proxy-call session control function (P-CSCF) selection by traffic type

Systems and methods discussed herein are directed to method for connecting a communication device to a data network via a network, e.g., a wireless communication network, and preventing the communication device from overriding a DNS selection by an operator of the network. The method includes receiving, from a communication device, e.g., an electronic device, a request to connect to a data network, e.g., the Internet, via a wireless communication network. A response message may be provided to the communication device, where the response message comprises (i) a configuration setting for the communication device to use domain name system (DNS) internet protocol (IP) addresses provided by an operator of the wireless communication network when accessing the data network and (ii) a data bit disabling the communication device from overriding the configuration setting. Connection of the communication device to the data network is then facilitated via the wireless communication network.

Wireless communication network operator defined DNS server selection

A technique of associating each Serving Gateway (SGW) with a corresponding Packet Data Network (PDN) gateway (PGW) to provide a particular type of wireless service to mobile devices in the wireless communication network is discussed herein. In configurations, the technique includes co-locating a SGW with a corresponding PGW in the same, physical node of the wireless communication network to provide a first S/PGW pair. In configurations, the first co-located S/PGW pair may be dedicated to provide data services to mobile devices in the wireless communication network. The technique also includes co-locating another SGW with a corresponding PGW in the same, physical node of the wireless communication network that is different from the physical node that includes the first S/PGW pair to provide a second S/PGW pair. In configurations, the second co-located S/PGW pair may be dedicated to provide voice services to mobile devices in the wireless communication network.
