Abstract

The disclosed technology is directed towards improving system usage of a communication network with respect to on-demand system information delivery for certain user equipment devices. When a first user equipment requests on-demand delivery of other system information block data (e.g., SIB2, SIB3, and so on) from a base station, a second device, and possibly other devices, can wait to receive the other system information block data via a broadcast response to the request. Configuration data can indicate that a user equipment device is to operate in the requesting mode or the non-requesting mode. While operating in the non-requesting mode, a device can request the data if not timely received. A device can change modes based on condition data, e.g., QoS of an application, remaining battery power and the like. The disclosed technology can conserve both user equipment resources and network resources.

First claim

What is claimed is:

1 . A user equipment, comprising:
a processor; and a memory that stores executable instructions that, when executed by the processor, facilitate performance of operations, the operations comprising:
processing configuration data indicating that the user equipment is to operate in a first mode in which other system information block data, other than data specified in minimum system information block data, is to be requested from a base station in response to receipt of the minimum system information block data from the base station, or is to operate in a second mode in which the other system information block data is not to be requested in response to the receipt of the minimum system information block data and is to be obtained via a broadcast communication of the other system information block data from the base station;
selecting according to the configuration data and a device specific condition determined by the user equipment, the first mode or the second mode, wherein the device specific condition is based on internal parameters of the user equipment including remaining battery power;
in response to the receipt of the minimum system information block data,
based on the device specific condition indicating that the user equipment is to operate in the first mode, requesting the other system information block data from the base station; and

based on the device specific condition indicating that the user equipment is to operate in the second mode, waiting, without requesting the other system information block data, for the other system information block data to be received via broadcast from the base station.

2 . The user equipment of claim 1 , wherein the configuration data is based on decision logic stored at the user equipment.

3 . The user equipment of claim 2 , wherein the operations further comprise switching between the first mode and the second mode in response a change in the internal parameters of the user equipment.

4 . The user equipment of claim 1 , wherein the device specific condition is further based on a classification of the user equipment, a contextual condition of the user equipment, a quality of service (QOS) requirement of the user equipment, or combinations thereof.

5 . The user equipment of claim 4 , wherein the classification of the user equipment corresponds to an ultra-reliable low latency communications device, and wherein the configuration data indicates that the user equipment is to operate in the first mode.

6 . The user equipment of claim 4 , wherein the classification of the user equipment indicates a device associated with a group of first responder devices, and wherein the configuration data indicates that the user equipment is to operate in the first mode.

7 . The user equipment of claim 4 , wherein the classification of the user equipment indicates an internet of things device, and wherein the configuration data indicates that the internet of things device is to operate in the second mode.

8 . The user equipment of claim 1 , wherein the user equipment is designated to operate in the first mode to request the other system information block data on behalf of a group of user equipment designated to operate in the second mode.

9 . The user equipment of claim 1 , wherein the waiting for the other system information block data to be received comprises listening for the other system information block data to be received for a specified duration, and wherein the operations further comprise, in response to the other system information block data not being received within the specified duration, requesting the other system information block data from the base station.

10 . The user equipment of claim 1 , wherein the waiting for the other system information block data to be received is based on a likelihood that the other system information block data has been previously requested by a different user terminal at a previous time, resulting in a likelihood that the other system information block data is obtainable via a broadcast communication from the base station at a next system information transmission window.

11 . The user equipment of claim 1 , wherein the configuration data comprises first configuration data, wherein the user equipment is operating in the first mode, and wherein the operations further comprise receiving second configuration data indicating that the user equipment is to operate in the second mode, and, in response to the receiving of the second configuration data, changing the user equipment to operate in the second mode to await the receipt of the other system information block data from the base station.

12 . The user equipment of claim 1 , wherein the configuration data comprises first configuration data, wherein the user equipment is operating in the second mode, wherein the broadcast communication of the other system information block data from the base station is a first broadcast communication, and wherein the operations further comprise receiving second configuration data indicating that the user equipment is to operate in the first mode, and, in response to the receiving of second configuration data, changing the user equipment to operate in the first mode, and requesting the other system information block data from the base station in response to receipt of a second broadcast communication of the minimum system information block data from the base station.

13 . A method, comprising,
receiving, by a user equipment comprising a processor, configuration data from a base station, the configuration data indicating that the user equipment is to operate in a first mode in which other system information block data, other than data specified in minimum system information block data, is to be requested from the base station in response to receipt of the minimum system information block data from the base station, or is to operate in a second mode in which the other system information block data is not to be requested in response to the receipt of the minimum system information block data and is to be obtained via a broadcast communication of the other system information block data from the base station; receiving, by the user equipment, minimum system information block data from the base station; selecting, by the user equipment according to the configuration data and a device specific condition determined by the user equipment, the first mode or the second mode, wherein the device specific condition is based on internal parameters of the user equipment including remaining battery power; in response to the receipt of the minimum system information block data, based on the device specific condition indicating that the user equipment is to operate in the first mode, requesting, by the user equipment, the other system information block data from the base station; and based on the device specific condition indicating that the user equipment is to operate in the second mode, waiting, by the user equipment, without requesting the other system information block data, for the other system information block data to be received via broadcast from the base station.

14 . The method of claim 13 , wherein the configuration data is first configuration data, wherein the user equipment is a first user equipment, and further comprising receiving, by a second user equipment, second configuration data from the base station, the second configuration data indicating that the second user equipment is to operate in a second mode in which the second user equipment is to await the other system information block data following receipt of an instance of the minimum sys
