Patent number: 9485750Abstract: 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.Type: GrantFiled: March 7, 2008Date of Patent: November 1, 2016Assignee: Google Technology Holdings LLCInventors: John M.

Patent number: 6792281Abstract: A wireless communication system (402) that provides dispatch communication service, and talk group calling service, supports several talk groups (408, 410). A console (412) operated by a subscribing organization resides outside of the communication system. The console is considered a member of the talk groups, and interacts with the communication system over an internet access, via one or more gateways (416, 418). The gateways operate like base stations that provide the air interface to the mobile communication devices. When the operator of the console wishes to patch the talk groups together, call information received from the first talk group at the console prompts the console to initiate a talk group call for the second talk group. When the second talk group call is set up, the console forwards call information such as identifiers and audio information to the second talk group. This allows the members of the second talk group to participate in talk group calls made in the first talk group.Type: GrantFiled: June 28, 2002Date of Patent: September 14, 2004Assignee: Motorola, Inc.Inventors: Steven D. Upp, Peter M. Drozt, Paul M. Erickson

Patent number: 6665283Abstract: A wireless communication system transmits data over a first link from a first mobile station (MS) to an infrastructure at a first speaker link power level, and over a second link from the infrastructure to a second MS at a first listener link power level, during a first time period. Each of the first power levels is designed to avoid the need for retransmissions of erroneously received data. Upon expiration of the first time period, data is transmitted over the first and second links at reduced power levels, which transmissions include retransmissions of erroneously received data. Error targets used in the transmission of data may also be adjusted after expiration of the first time period. In addition, the power levels and error rate targets may be individually adjusted on a link-by-link basis based on the RF loading of each link and/or based on error metrics determined for each link.Type: GrantFiled: October 5, 2001Date of Patent: December 16, 2003Assignee: Motorola, Inc.Inventors: John M.

Patent number: 6067457Abstract: A priority scheme for a system that supports dispatch and telephone services whereby more important calls, of the type spanning across the same or multiple cells, are dynamically assigned higher positions in the queue for the next voice channel to become available. Less important calls are readily identified and can have their voice channel taken away, i.e., dropped, to provide a channel for an emergency call. The priority scheme also makes it possible to for the priority of call in progress to dynamically change, e.g., increasing priority over time so that its voice channel can't be taken away by a higher priority call, or decreasing priority of call as a function of time in progress.Type: GrantFiled: April 30, 1996Date of Patent: May 23, 2000Assignee: Motorola, Inc.Inventors: Paul M.

Patent number: 5987021Abstract: In a resource allocator (106), a reserved resource group comprising at least one communication resource is maintained for use in supporting non-queued services. When a request for the at least one non-queued service is received, a communication resource from the reserved resource group is allocated to the request (305). When the reserved resource group becomes depleted, at least one more communication resource is assigned to the reserved resource group with greater preference relative to allocation of communication resources to requests for at least one queued service (307). In a preferred embodiment, a communication resource is assigned to the reserved resource group prior to allocating resources to any queued service requests. Additionally, communication resources (200) having varying grades of service can be accommodated.Type: GrantFiled: June 2, 1998Date of Patent: November 16, 1999Assignee: Motorola, Inc.Inventors: Paul M.
