Enhanced paging mechanism for machine type communication

摘要

Enhanced paging mechanisms are proposed for Machine Type Communication (MTC) devices in 3GPP networks. First, adaptive paging is proposed to adaptively allocate extra paging occasions for MTC devices with no extra procedure or power consumption on normal UEs. Second, group paging is proposed to simultaneously page a plurality of MTC devices with one paging. Group paging is controlled in different levels for optimized signaling and easier management. In one embodiment, group broadcasting and group release are used. Third, paging with response policy is proposed to pre-define or dynamically configure paging response policies for MTC devices.

1. A method comprising:
receiving a paging message transmitted for one or multiple groups of machine-to-machine (M2M) from a base station by a M2M device in a mobile communication network, wherein the base station is a fixed infrastructure unit in the mobile communication network, wherein the paging message embeds a paging response type of either a mobile originate (MO) type or a mobile termination (MT) type, wherein the MT type indicates the M2M must wake up to establish a connection automatically and the MO type indicates the M2M needs to decide whether to wake up to establish connection automatically; determining whether to respond to the paging message based on a paging matching rule, one or more paging response policy, and the paging response type, wherein each paging response policy applies to one or more M2M; establishing a connection with the base station in the mobile communication network; and receiving a group broadcasting message from the base station, wherein the group broadcasting message contains a group Radio Network Temporary Identifier (G-RNTI).
