Problems solved by technology

Because a given paging occasion occurs at different time points in different cells due to lack of synchronization of SFN between cells, and because the UE may perform cell reselection during the DRX sleep period, the paging occasion may be missed

Embodiment Construction

[0065] Embodiments herein are described in the sense of an LTE network with EPC. Embodiments herein can also be applied to other cellular and wireless systems that also use paging, such as GSM and WCDMA / UMTS.

[0066] The embodiments herein propose methods implemented in wireless communication devices and core network nodes. In the following the MME is used as an example of a core network node, but in general it can also be another node controlling the sending of paging messages, for example for UMTS and GSM the applicable CN node is the SGSN.

[0067] The wireless communication device will take UE as an example. There is a base station node between the wireless communication device and the core network node, and the base station node will dispatch paging messages to the wireless communication device through the radio link. Hereinafter an eNB is used as an example of a base station node.

[0068] In the embodiments herein, when the wireless communication device registers wi...

Abstract

A method performed by a wireless communication device for monitoring paging messages from a core network node in a wireless communication network. The wireless communication device monitors (304) for paging messages at one or more paging occasions during a time period for monitoring for paging. The start of the time period is based on the moment when the wireless communication device registers with the core network node.

Description

technical field [0001] Embodiments herein relate to a wireless communication device, a core network node and a method therein for handling extended DRX cycles in a wireless communication system. Specifically, they relate to monitoring and providing paging messages during paging time periods. [0002] They may also involve determining paging occasions when using extended paging cycles longer than the frame number range. Background technique [0003] In a typical radio communication network, wireless communication devices (also referred to as mobile stations and / or user equipment (UE)) communicate with one or more core networks (CN) via a radio access network (RAN). A radio access network covers a geographical area divided into cell areas, each cell area is served by a base station, such as a radio base station (RBS), which in some networks may also be referred to as, for example, a "NodeB" or an Evolved Node B (eNB, eNodeB). A cell is a geographical area where radio covera...
