A system embodying the subject disclosure includes a memory to store instructions. A controller coupled to the memory, responsive to executing the instructions, can perform operations including obtaining performance characteristics for segments of a network; the segments are selected based on a trajectory of a mobile device coupled to the network. The controller can predict future transport and segment characteristics based on the performance characteristics. The controller can receive a request from the mobile device for transmission of a data packet over the network. The controller can monitor a power state of the mobile device and predict a future power state of the mobile device. The controller can determine a target time for fulfilling the request, based on the future power state and the future transport and segment characteristics. The controller can schedule a time for fulfilling the request according to the target time. Other embodiments are disclosed.

A method for policing APN-AMBR includes, at P-GW including plural P-GW DP worker instances: receiving, uplink data to be transmitted over a non-GBR bearer associated with a first PDN session from a first UE via an AP or downlink data to be transmitted over the non-GBR bearer to the first UE via the AP; forwarding the uplink or downlink data to a first P-GW DP worker instance of the plurality of P-GW DP worker instances that is assigned to the PDN session; and, at the first P-GW DP worker instance, transmitting, to an APN-AMBR policer separate from the P-GW, a request for a slice of APN-AMBR capacity for processing the uplink or downlink data. The method further includes, at the APN-AMBR policer: maintaining records of APN-AMBR capacity used by UEs having PDN sessions assigned to different ones of the P-GW DP worker instances; and granting or denying the request based on the APN-AMBR capacity used by the PDN sessions assigned to the different ones of the P-GW DP worker instances.

A mobile application gateway configured to interconnect mobile communication devices on a cellular network with an enterprise network is provided. The mobile application gateway includes a voice and data signaling gateway configured to provide routing functionalities, service functionalities and admission control. A gateway GPRS support node (GGSN) is configured to establish a secure data session between one or more of the mobile communication devices and the enterprise network by establishing a GPRS tunneling protocol (GTP) tunnel between a carrier-hosted serving GPRS support node (SGSN) and the GGSN.

A WebRTC system, device and method enabling a P2P communication when both ends of a communication are WebRTC enabled devices. The system and devices also enable a WebRTC client to SIP device communication. A SIP interworking function is configured to receive a SDP1 from an originating WebRTC and obtain local media information from a media interworking function. The first SIP interworking function is configured to create a SDP2 based on the SDP1 and the local media information, create a SIP message comprising a message-body field including the SDP2 and an SIP extension header field including the SDP1, and send the SIP message to an IMS or SIP server.

Aspects of the subject disclosure may include, for example, a method comprising obtaining media content; receiving a request from equipment of a user to view the media content; identifying a predicted field of view of the user; sending a base layer of the media content to the equipment of the user using a first stream; and sending a first enhancement layer of the predicted field of view to the equipment of the user using a second stream. The first stream and the second stream may utilize different protocols, different servers, different buffer sizes, and/or a combination thereof. While the first stream may include an entire 360 degrees of the base layer of the media content, the second stream may be limited to the first enhancement layer of the predicted field of view of the media content. Other embodiments are disclosed.

A flow tagging technique includes tagging a data flow at a plurality of points in the data flow. For example, the data flow can be tagged at a socket and at a proxy manager API. By tagging the data flow at multiple points, it becomes possible to map network service usage activities to the appropriate initiating applications.

A relay device for call processing according to an embodiment may include: a database; a protocol relay unit; a call processing unit for checking whether a sender and recipient of a call are subscribers stored in the database, on the basis of an income SIP signal through the protocol relay unit, and providing the income SIP signal to an external call routing server when the sender of the call is the subscriber and the recipient of the call is not the subscriber; and a packet processing unit for rearranging incoming call packets of the call according to the sequence of the call packets and adjusting transmission speed of the rearranged call packets according to the situation in which the call packets are incoming.

A gateway device receives interface information sent by an interface extension device, where an Ethernet interface of the interface extension device is connected to a target Ethernet interface of the gateway device, and the interface information includes an interface type and a media access control (MAC) address of a first non-Ethernet interface of the interface extension device. The gateway device creates a first virtual interface on the target Ethernet interface based on the interface information, where the first virtual interface corresponds to the first non-Ethernet interface, and an interface type of the first virtual interface is an Ethernet interface. The gateway device sends an interface creation success notification to the interface extension device. The gateway device may obtain data of the first non-Ethernet interface through the first virtual interface, thereby implementing interface extension of the gateway device.

The method performed by a gateway between a LAN and a WAN that includes a platform of the VoIP telephone service, is characterized in that it includes a step of activating the VoIP telephone service on detecting a connected state of a terminal connected to the gateway.
