[0033] Similar to the first embodiment, it is conceivable that a later measurement result does not satisfy the additional measurement. When this occurs, the measurement interval is chosen such that the corresponding threshold can satisfy the current measurement result. If none of these thresholds are met, the measurement interval is doubled. Ultimately, if at N A3e If none of the smart measurement thresholds are met in consecutive measurements, set the measurement interval bar back to the original value of 1280ms.

[0034] The above discussion focuses on more frequent measurements of mobile performance. In fact, the proposed smart measurement also includes measurement reduction for power saving purposes. When the connection with the serving cell is always in a good condition (such as a stationary UE), a measurement interval longer than the DRX cycle can be configured. Note that measurement event A3 is used as an example, other measurement events and criteria can also be us...

Abstract

A method of mobility management with smart measurement is proposed. The present invention addresses modifications on RRM measurements as well as mobility control procedures in order to improve mobility performance for UE configured with longer connected mode DRX cycle. Since the poor mobility performance when applying extended DRX cycle mainly results from reduced number of measurements, one solution is to dynamically adjust the measurement interval so as to trigger the measurement reporting in time.

Description

[0001] Cross References to Related Applications [0002] The claims of this application claim priority to US Provisional Application No. 62 / 194,363, filed July 20, 2015, entitled "Measurement Enhancements for LTE Systems." The entire contents of the aforementioned US Provisional Application are hereby incorporated by reference. technical field [0003] The present invention relates to wireless communication systems, and more particularly, to UE measurement and mobility control procedures for Long Term Evolution (LTE) systems. Background technique [0004] LTE systems offer high peak data rates, low latency, improved system capacity, and low operating costs due to simple network structures. And the LTE system also provides seamless integration with old wireless networks (such as GSM). Consideration needs to be given to enhancing the LTE system so that it can meet or exceed the IMA advanced fourth generation (4G) standard. One of the key enhancements is support for bandwid...
