UE Paging Response via Pre-Allocated Uplink Resources
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In existing M2M communication systems, the process of paging user equipment (UE) by an access network device involves multiple signaling exchanges, leading to high network resource consumption and low data transmission efficiency, especially when UE is in an idle, non-synchronous, or loose synchronous state.
Innovation Solution
The UE sends paging response information using an unscheduled or shared uplink data sending resource without initiating a random access process, reducing signaling exchanges and optimizing network resource allocation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the UE establishes a radio link to the access network device by means of random access, then the UE can send paging response information to the access network device, but there are multiple times of signaling exchange between the UE and the access network device, occupying a relatively large quantity of network resources and reducing data transmission efficiency
Solution Approach 1:
The access network device pre-allocates uplink data sending resources to the UE before the UE needs to send paging response information. This preliminary resource allocation eliminates the need for random access procedures when the UE needs to respond to paging, thereby reducing signaling exchange times and improving data transmission efficiency while ensuring reliable paging response delivery

AI summary
Embodiments of the present invention provide a paging method, a device, and a system, and relate to the communications field, so as to reduce signaling exchange performed when an access network device pages UE, save a network resource, and improve data transmission efficiency. The paging method includes: receiving, by user equipment (UE), paging information sent by an access network device, where the paging information is used to instruct the UE to send a paging response by using an uplink data sending resource; and obtaining, by the UE, the uplink data sending resource according to the paging information, and sending paging response information to the access network device by using the uplink data sending resource.
