Abstract

An apparatus and a method for implementing a paging mechanism in a wireless LAN, for example, a wireless LAN according to the Hiperlan 2 Technical Specification, for allowing a base station, or an access point, to page a mobile terminal that is not connected with, or associated with, the access point. The present paging mechanism is implemented by transmitting a broadcast channel message that includes an indication that a paging message is included in the current data frame, a second broadcast channel message that includes the information specific to the paging message, and a third broadcast channel message that include information regarding the location of the second broadcast channel message in the data frame. In response to the broadcast channel message indicating the presence of the paging request, the mobile terminal acquires the second and third broadcast channel messages and determines whether the paging request is intended for the mobile terminal

Claims

1. A method for paging a mobile terminal that is disassociated from an access point in a wireless LAN, comprising the steps of:

receiving a paging request in a link control layer from a convergence layer;

generating in the link control layer a first broadcast channel message including data indicative of the presence of the paging request;

generating in the link control layer a second broadcast channel message having data representative of the paging request; and

transmitting the first broadcast channel message and the second broadcast channel message over a broadcast channel.

2. A network access point for transmitting a paging request to a mobile terminal that is not currently associated with the network access point, comprising:

receiving means coupled to a core network for receiving a paging request in a link control layer;

the link control layer for generating a first broadcast channel message having data indicative of the presence of the paging request and for generating a second broadcast channel message having data representative of the paging request;

receiving means coupled to the link control layer for transmitting the first broadcast channel message and the second broadcast channel message over a broadcast channel.

3. The network access point according to claim 2, wherein the transmitting means transmits the paging request during predetermined intervals defined by a paging group of a target device.
