Patent number: 9408065Abstract: A device (34) facilitates communications on behalf of users from various public service agencies (22-32). An example device (34) is implemented at a core layer such that it is capable of interfacing with a plurality of wireless communication network elements. An example device (34) includes a database portion (36) that includes information regarding how wireless communications should be managed on behalf of individuals associated with one or more public service agencies. A communication portion (38) interfaces with one or more network elements to provide information from the database portion (36) to achieve the desired control over wireless communications on behalf of end users from the public service agencies. Control portions (40) provide information and management capabilities to agencies utilizing the device (34).Type: GrantFiled: November 24, 2014Date of Patent: August 2, 2016Assignee: Alcatel LucentInventors: Tewfik Doumi, Hanan M. Novotny, Anish Sankalia

Patent number: 8976730Abstract: For voice traffic over-the-air in LTE, persistent schedule (PS) or semi-persistent (SPS) scheduling would be the preferred method as they minimize signaling messages. In PS or SPS, resources are pre-allocated to the UE 402 at regular intervals (e.g., every 20 milliseconds). At each time slot, the UE will generally transmit an IMBE frames which are encoded in ISSI packet. In ISSI, other data streams are multiplexed with the IMBE frame and thus the packet size varies depending on its position within a super-frame. For PS or SPS, eNodeB must allocated sufficient resources to support the largest packet that. Therefore, there is spare capacity when the packet is not of the largest size. The exemplary embodiments specify ways to use spare capacity to transfer data.Type: GrantFiled: July 22, 2011Date of Patent: March 10, 2015Assignee: Alcatel LucentInventors: Thomas P.

Patent number: 8792340Abstract: Embodiments of the present invention are directed to providing a method and system for call admission control for a Long Term Evolution (LTE) network shared between a plurality of user classes, such as, for example, a public safety user class and a consumer user class. An admission control module oversees the call admission process based on a specified policy profile. When there are insufficient resources in the network to support an incoming call, the admission control module will consult with a preemption module to determine whether, by preemption of lower priority calls, enough resources can be recovered to support the incoming call.Type: GrantFiled: June 14, 2010Date of Patent: July 29, 2014Assignee: Alcatel LucentInventors: Thomas P. Chu, Tewfik Doumi, Dong Sun

Patent number: 8656029Abstract: Methods, systems, and apparatuses dynamically setting up bearers to support Internet protocol (IP) multicast traffic in various networks are provided. The method may be performed by joining an IP multicast group in response to receiving a request to initiate an IP multicast transmission session within a network, the request including at least one transmission session parameter; determining at least one synchronization area within the network for the IP multicast transmission session of the request based at least in part on the at least one transmission session parameter; and initiating an IP multicast transmission session between an application server and at least one user equipment end-point within the at least one synchronization area.Type: GrantFiled: June 30, 2011Date of Patent: February 18, 2014Assignee: Alcatel LucentInventors: Thomas P. Chu, Tewfik Doumi, Kenneth C. Budka

Patent number: 8422448Abstract: A method and system for group call control in a broadband wireless network. A group call (push-to-talk) server initiates and regulates group call communication sessions. A wireless base station communicates with one or more group call participants. When a request to participate in a group call is received, it is examined to see if it contains a group call ID or other group call indicator. If not, regular call resources are allocated, if available. If so, it is determined whether another group member is attached to the base station. Group call resources are then reserved, if available, based on this determination. The resources allocated for the group call may also depend on whether the system supports multicast on the downlink to group members, or whether losing audio is supported. In some embodiments, network resources may be reallocated to support the group call.Type: GrantFiled: September 30, 2010Date of Patent: April 16, 2013Assignee: Alcatel LucentInventors: Thomas P. Chu, Tewfik Doumi, Ramesh Nagarajan

Patent number: 8379517Abstract: Embodiments of the present invention are directed to providing a method and system for call admission control and preemption of multiple bit-rate applications in a digital communication system. Multiple bit-rate applications such as streaming video can specify a Quality of Service (QoS) profile having multiple levels. When there are insufficient resources in the network to support an incoming multiple bit-rate call, the system determines whether, by reducing the bit-rate of the incoming call or by preemption of lower priority components of existing calls, enough resources can be recovered to support the incoming call.Type: GrantFiled: June 14, 2010Date of Patent: February 19, 2013Assignee: Alcatel LucentInventors: Thomas P.
