  • Patent number: 9485750
    Abstract: A method for paging a mobile station where the mobile station (208-212) may be in a dormant state is described. The method begins by sending a first paging message (302) in a first zone (214) of a given area to a selected mobile station wherein the first paging message is sent at the beginning of a paging interval (300). A base station (202-206) then receives a response to the paging message when the mobile station is in the first zone. When the response to the first paging message is not received, a second paging message (306) is sent in a second zone (216) of the given area. The second paging message is sent at a first offset (308) from the sending of the first paging message wherein this first offset occurs less than one paging interval after the sending of the first page message.

  • Publication number: 20040082352
    Abstract: A method, equipment, and environment for dynamically controlling a wireless group call and group call participants in a manner that provides and enables accurate billing of each call participant. The methodology involves selecting a group of mobile stations to participate in the wireless group call (30) and causing an invitation message to be transmitted to the group of mobile stations (34). The methodology then includes setting up a dynamic group of mobile stations based on replies received from the group of mobile stations (36), preferably by editing the dynamic group of mobile stations, and then validating the mobile stations in the dynamic group as members of the wireless group call (38).
