Embodiment Construction

[0013] The following detailed description refers to the accompanying drawings that show, by way of illustration, specific details and embodiments in which the invention may be practiced.

[0014] The word "exemplary" is used herein to mean "serving as an example, instance, or illustration." Any embodiment or design described herein as "exemplary" is not necessarily to be construed as preferred or advantageous over other embodiments or designs.

[0015] Components of a communications device (eg, an applications processor) may, for example, be implemented by one or more circuits. A "circuit" may be understood as any kind of logic-implementing entity, which may be a dedicated circuit or a processor executing software stored in memory, firmware, or any combination thereof (eg, an operating system). Thus, a "circuit" may be a hardwired logic circuit or a programmable logic circuit such as a programmable processor, eg, a microprocessor. A "circuit" may also be a processor executin...

Abstract

A communications device may include a host computer and a modem interconnected by an interface. The host includes a host processor configured to control components of the communication device and communicate with the modem via an interface. The modem includes a modem processor configured to control components of the modem and communicate with the host via an interface; and a transceiver configured to communicate with the modem processor and send data to and from the communication network The network receives the data. The modem processor is configured to identify a reduced activity state of the modem and communicate information regarding the reduced activity state to the host processor. The host processor is configured to reduce operation of at least one component of the communication device in response to the information about the reduced activity state of the modem.

Description

technical field [0001] Aspects of the present disclosure relate generally to power saving host-modem interactions in communication devices, particularly wireless communication devices. Background technique [0002] A computerized communication device for a (public or private) communication network may typically have an architecture comprising a host system and a modem system interconnected by an internal interface (eg, an interprocessor communication (IPC) interface). The host system may include a host processor for controlling components of the communication device and for communicating via an interface with the modem system, while the modem system includes a modem processor for controlling components of the modem system and for interfacing with the host system to communicate. A modem system generally includes a transceiver arranged to communicate with the modem processor and to send data to and receive data from the communication network. [0003] In a wireless environme...
