Quality of service based CDMA broadcast scheduler
First Claim
1. A method for scheduling a transmission time of a message to be transmitted in a telecommunications system, said method comprising the steps of:
- computing a respective first message valid time period for at least one sector in the telecommunications system based on a length of the message, a received second message valid time period and number of users in the respective at least one communication area, said second message valid time period being associated with the message; and
scheduling a respective transmission time of the message in the at least one communication area based on the computed respective first message valid time period.

Abstract
A computer implemented method and apparatus that schedules broadcast short message service (BSMS) messages in a manner that reduces the adverse impact on voice quality and system capacity, attributable to the transmission of the BSMS messages, in a wireless telecommunications system. The method and apparatus utilize a quality of service (QoS) based broadcast message scheduler to negotiate and schedule the transmission times of BSMS messages to the individual users in the system. The quality of service (QoS) based broadcast message scheduler also allows a user to tradeoff voice quality for broadcast capacity.

11. A method of scheduling a transmission time of a short message service message to be transmitted to at least one user of a telecommunications system, said method comprising the steps of:
-
determining a message length and first message valid time period from the short service message;
determining a respective number of users in at least one sector of the telecommunications system;
computing a respective received second message valid time period for the at least one communication area based on the message length, first message valid time period and number of users in the respective communication area; and
scheduling a respective transmission time of the message for at least one user in the at least one communication area based on the respective computed second message valid time period. - View Dependent Claims (12, 13, 14, 15, 16)

17. A wireless telecommunications system comprising:
-
a mobile switching center, said mobile switching center including a first programmed processor for scheduling a transmission time of a message to be transmitted in said system and for computing a first message valid time period for a communication area in said system based on a length of the message, a second received message valid time period and number of users in the communication area, said second received message valid time period being associated with the message; and
a base station coupled to said mobile switching center, said base station comprising a second programmed processor for scheduling a respective transmission time of the message for at least one user in the communication area based on the computed first message valid time period. - View Dependent Claims (18, 19, 20, 21, 22, 23, 24, 25, 26, 27, 31)

28. A wireless telecommunications system comprising:
-
a mobile switching center, said mobile switching center comprising a first controller, said first controller computing a respective first message valid time period for at least one sector in said system based on a length of a received message, a second received message valid time period and number of users in the respective at least one communication area; and
a base station coupled to said mobile switching center, said base station comprising a second controller, said second controller scheduling a respective transmission time of the message for at least one user in the at least one communication area based on the respective computed first message valid time period.
