Abstract:
A selective call blocking function (SCBF) device, included in an internet protocol (IP) multimedia subsystem (IMS), processes a request to establish an IP call on an LTE network, such as a voice over long term evolution (VoLTE) call. The SCBF device identifies a user equipment (UE) associated with the IP call and an associated eNode B (eNB). For example, the SCBF may access a subscriber location memory to determine a location of the UE and an eNB associated with the location. The SCBF determines whether the eNB supports the IP call, and permits the IP call to be established via the IMS when the eNB supports the IP call. When the eNB does not support the IP call, the SCBF blocks the IP call and initiates a non-IP call, such as a 1× call, to the UE to prevent communications interruptions.
Abstract:
A device is configured to obtain network information indicating an amount of client devices, of each device type, registered in an operator network. The device is configured to obtain client device information identifying a client device and determine a device type of the client device based on the client device information. The device is configured to determine a frequency for the client device to use to communicate with the operator network based on the device type of the client device and the amount of client devices of each of the device types registered in the operator network. The device is configured to provide an instruction to the client device to use the frequency to communicate with the operator network.
Abstract:
A device is configured to obtain base station information for base stations indicating whether data communicated via a respective base station should receive optimization processing. The device may obtain a base station identifier from a base station. The device may determine whether the data communicated via the base station should receive the optimization processing based on the base station information and the base station identifier. The device may receive non-optimized data to be sent to a client device via the base station. The device may selectively cause the optimization processing to be performed on the non-optimized data based on whether the data communicated via the base station should receive the optimization processing. The device may provide optimized data generated by the optimization processing or the non-optimized data to the client device via the base station based on selectively causing the optimization processing to be performed.
Abstract:
A server device may determine session information that identifies a quantity of sessions established between each of one or more serving gateways (SGWs) and a packet data network (PDN) gateway (PGW); and direct a mobility management entity (MME) to assign additional sessions between the one or more SGWs and the PGW based on the session information.
Abstract:
A user device may be configured to identify a received transport bearer channel, via which a group of content streams are received, the transport bearer channel including a group of logical bearer channels that each correspond to a particular transport layer session, each transport layer session corresponding to a particular one of the content streams; receive a selection of a particular content stream, of the group of content streams; identify a particular logical bearer channel, of the group of bearer channels, that corresponds to the particular content stream; extract a transport layer session from the identified particular logical bearer channel; provide, from a transport layer of the user device and to an application layer of the user device, the particular content stream from the transport layer session; and present the particular content stream.
Abstract:
A method for determining a Quality of Service (QoS) policy can be based on requested bandwidth. The method may initially receive a connection request which includes a requested bandwidth that corresponds to an application. The method may then determine a policy for an application data flow associated with the application based on the connection request. A bandwidth designation, which is based on the requested bandwidth, may be assigned to the application data flow based on the determined policy. Finally, the policy and the bandwidth designation may be provided so that a bearer can be assigned.
Abstract:
One or more server devices may determine a measure of popularity of multiple content items; select particular content to be provided via a multicast channel when the measure of popularity of the particular content satisfies a threshold; generate a notification regarding the availability of the particular content; and provide the notification to one or more user devices for display on the one or more user devices to notify respective users regarding the availability of the content. The notification may be received by the one or more user devices outside of a multicast control channel. The one or more servers may transmit the particular content via the multicast channel.
Abstract:
A device may receive a packet that includes priority information that is based on a priority assigned to bits included in the packet. The priority may be assigned based on scalable code used to encode the bits for transmission. The device may determine that an indicator of network congestion satisfies a threshold, and may schedule the packet for transmission to a user device based on the priority information and the determination that the indicator satisfies the threshold.
Abstract:
A device may receive information that identifies a radio frequency condition of a user device, where the radio frequency condition indicates a quality of a radio access network connection of the user device. The device may determine a radio frequency parameter value based on the radio frequency condition, and may set a data rate for a transmission control protocol (“TCP”) communication with the user device based on the radio frequency parameter value.
Abstract:
Traffic flows in a wireless network may be optimized based on a current state of the wireless network as well as based on information received from mobile devices attached to the wireless network. In one implementation, a method may include receiving, from mobile devices attached to the wireless network, values for parameters associated with applications that are executed by the mobile devices. The method may further include receiving, from network elements in the wireless network, information relating to a state of the wireless network; and determining based on the values for the parameters associated with the applications and based on the information relating to the state of the wireless network, modifications to an operation of the wireless network to optimize transmission of the traffic flows in the wireless network with respect to the parameters.
