Abstract
Methods and apparatus to avoid transmission of redundant neighbor cell information to mobile stations. An example method to avoid transmission of at least some neighbor cell system information from a network to a mobile station disclosed herein comprises receiving neighbor cell system information, setting a validity indication representing whether the mobile station has valid neighbor cell system information associated with a neighbor cell, and sending the validity indication to the network.
Claims19
A method to avoid transmission of at least some neighbor cell system information from a network to a mobile station, the method comprising:
- receiving neighbor cell system information;
- setting a validity indication indicating whether the mobile station has valid neighbor cell system information associated with a neighbor cell, the validity indication to indicate that a first portion of the neighbor cell information is valid if the first portion of the neighbor cell information was received correctly within a preceding first specified time period but not if the first portion of the neighbor cell information was received before the preceding first specified time period, the neighbor cell system information corresponding to system information broadcast by the neighbor cell;
- and
- sending a message identifying the neighbor cell and including the validity indication to the network if the validity indication was not already sent within a preceding second time period via a second message.
A method to avoid transmission of at least some neighbor cell information from a network to a mobile station, the method comprising:
- receiving, from the mobile station, a message identifying a neighbor cell and including a validity indication indicating whether the mobile station has valid neighbor cell information associated with the neighbor cell identified in the message, the validity indication to indicate that a first portion of the neighbor cell information is valid if the first portion of the neighbor cell information was received correctly by the mobile station within a first specified time period preceding sending of the message but not if the first portion of the neighbor cell information was received by the mobile station before the first specified time period, the neighbor cell information corresponding to system information broadcast by the neighbor cell, the mobile station to send the message including the validity indication to the network if the validity indication was not already sent by the mobile station within a preceding second time period via a second message;
- and
- determining whether to schedule sending of the neighbor cell information associated with the neighbor cell to the mobile station based on the received validity indication.
