摘要

A method may include receiving content for multicasting, identifying user equipment (UE) devices to receive the content and identifying a geographical or service area associated with the identified UE devices. The method may also include determining a scheduled time for a multicast transmission of the content and transmitting, prior to the scheduled time, a message to the devices, wherein the message indicates the scheduled time. The method may further include initiating the multicast transmission of the content at the scheduled time.

BACKGROUND INFORMATION

Certain types of devices, such as Internet of Things (IoT) devices, are designed to be used with infrequent or no battery charging. Therefore, conserving battery life impacts nearly all decisions regarding operation and use of such devices. For example, to conserve the battery, IoT devices typically use low power processors and real time operating systems that can frequently stop and start. IoT devices also typically use special modems that use only a limited part of a wireless network radio frequency spectrum.

Despite these limitations, IoT devices have many of the same data intensive operational needs as more traditional user devices. For example, IoT devices may periodically require firmware updates to continue operating properly, as well as require new features to address bugs (e.g., software bugs).

In addition, IoT devices typically have limited power cycles. For example, typical IoT devices power on very infrequently to receive and process queued messages (e.g., once per day). Since many IoT devices may wake at different times during the day, updating such devices typically consumes a large amount of network resources and IoT resources (e.g., battery life).

What is claimed is:1. A method, comprising:receiving, by at least one network device associated with providing multicast services, content for multicasting;identifying, by the at least one network device, a plurality of user equipment (UE) devices to receive the content;identifying at least one of a geographical or service area associated with the identified plurality of UE devices;identifying, by the at least one network device, a time when at least some of the plurality of UE devices will be awake;determining, by the at least one network device, a scheduled time for a multicast transmission of the content;transmitting, by the at least one network device and at the identified time, a message to the plurality of UE devices, wherein the message indicates the scheduled time; andinitiating, by the at least one network device, the multicast transmission of the content at the scheduled time.2. The method of claim 1, wherein the at least one network device comprises a device management platform and a broadcast system, the method further comprising:providing, by the device management platform, the scheduled time to the broadcast system via an application programming interface.3. The method of claim 1, further comprising:receiving, by the at least one network device, a message from at least some of the plurality of UE devices, wherein the message indicates that the multicast content was successfully received.4. The method of claim 3, further comprising:determining, by the at least one device, whether to schedule another multicast session based on a number of received messages indicating that the multicast content was successfully received.5. The method of claim 1, wherein the content comprises at least one of a firmware update or a software update for the plurality of UE devices, andwherein the identifying the time when at least some of the plurality of UE devices will be awake comprises:accessing, by the at least one network device, a schedule to identify the time.6. The method of claim 1, wherein the receiving content comprises receiving content from an entity associated with managing the plurality of UE devices, and wherein the content is received by the at least one network device via an application programming interface.7. The method of claim 1, wherein the plurality of UE devices comprise Internet of Things (IoT) devices and the message identifies a wireless channel via which the plurality of IoT devices are to obtain the content.8. The method of claim 1, further comprising:repeating the multicast transmission a plurality of times.9. The method of claim 1, further comprising:providing, to the plurality of UE devices, software configured to perform power management at each of the respective UE devices, wherein the software is configured to signal at least a modem on the UE device to awake prior to the scheduled multicast transmission.10. A system, comprising:at least one device configured to:receive content for multicasting,identify a plurality of user equipment (UE) devices to receive the content,identify at least one of a geographical or service area associated with the identified plurality of UE devices,identify a time when at least some of the plurality of UE devices will be awake,determine a scheduled time for a multicast transmission of the content,transmit, at the identified time, a message to the plurality of UE devices, wherein the message indicates the scheduled time, andinitiate the multicast transmission of the content at the scheduled time.11. The system of claim 10, wherein the at least one device comprises a device management platform and a broadcast system, whereinthe device management platform is configured to provide the scheduled time to the broadcast system via an application programming interface.12. The system of claim 10, wherein when identifying the time when at least some of the plurality of UE devices will be awake comprises:accessing, by the at least one device, a schedule to identify the time, and wherein the at least one device is further configured to:receive a message from at least some of the plurality of UE devices, wherein the message indicates that the multicast content was successfully received.13. The system of claim 12, wherein the at least one device is further configured to:determine whether to schedule another multicast session based on a number of received messages indicating that the multicast content was successfully received.14. The system of claim 10, wherein the content comprises at least one of a firmware update or a software update for the plurality of UE devices and wherein the at least one device is further configured to:repeat the multicast transmission a plurality of times.15. The system of claim 10, wherein the plurality of UE devices comprise Internet of Things (IoT) devices and when transmitting the message, the at least one device is configured to:include, in the message, information identifying a wireless channel via which the plurality of IoT devices are to obtain the content.16. The system of claim 10, wherein the at least one device is further configured to:provide, to the plurality of UE devices, software configured to perform power management at each of the respective UE devices, wherein the software is configured to signal at least a modem on the UE device to awake prior to the scheduled multicast transmission.17. A non-transitory computer-readable medium having stored thereon sequences of instructions which, when executed by at least one processor included in a network device, cause the at least one processor to:receive content for multicasting;identify a plurality of user equipment (UE) devices to receive the content;identify at least one of a geographical or service area associated with the identified plurality of UE devices;identify a time when at least some of the plurality of UE devices will be awake;determine a scheduled time for a multicast transmission of the content;transmit, at the identified time, a message to the plurality of UE devices, wherein the message indicates the scheduled time; andinitiate the multicast transmission of the content at the scheduled time.18. The non-transitory computer-readable medium of claim 17, wherein the instructions further cause the at least one processor to:determine whether to schedule another multicast session based on a number of received messages indicating that the content was successfully received.19. The non-transitory computer-readable medium of claim 17, wherein the plurality of UE devices comprise Internet of Things (IoT) devices and when transmitting the message, the instructions further cause the at least one processor to:include, in the message, information identifying a wireless channel via which the plurality of IoT devices are to obtain the content.20. The non-transitory computer-readable medium of claim 17, wherein the content comprises at least one of a firmware update or a software update for the plurality of UE devices, and the instructions further cause the at least one processor to:include, in the message, information identifying a wireless channel via which the plurality of IoT devices are to obtain the content.
