A method for communicating additional network information using a synchronization identifier is presented. A synchronization identifier is defined. The synchronization identifier is used for the purpose of synchronizing communication between a Mobile Station (MS) and a network. In addition, the synchronization identifier is used to define additional functionality in the wireless network. As such, the synchronization identifier may be used to communicate information about wireless services and/or wireless components between the MS and the network.

Method for updating and managing synchronization identifier by using release messages or status request and response

A call flow is provided in a wireless communication system to enable quality of service (QoS) parameters to be retrieved and provided to a base station when a wireless device requests service. The QoS parameters may include or represent a QoS profile associated with the wireless device, a QoS profile associated with a user of the wireless device, or a QoS policy for a session involving the wireless device. The base station uses the QoS parameters to control access to the system by the wireless device. Another call flow is provided to transfer the QoS parameters from the base station to a packet control function for storage when a packet data session associated with the wireless device becomes dormant. If the packet data session is later reactivated, the QoS parameters are provided from the packet control function back to the base station.

Admission control and policing in wireless packet data communication system

A wireless communications network includes a first base station system that performs wireless communications according to a first protocol (e.g., 1xEV-DO protocol) and a second base station system that performs wireless communications according to a second, different protocol (e.g., IS-2000). A link is provided between the first and second base station systems to enable a network-initiated handoff procedure. If a source base station system detects that a handoff of a mobile station to a target base station system is required, the source base station system exchanges messaging over the link with the target base station system to perform the handoff. In one example, the handoff is a hard handoff.

Method and apparatus to control handoff between different wireless systems

A packet data service node (PDSN) is formed to establish a connection with a plurality of mobile terminals by way of one or more packet control function cards or devices. A packet control function (PCF) card or device is formed to provide an interface between the packet data domain and wireless domain and further to inform a base station controller/access network controller (BSC/ANC) to block the setup and establishment of any additional communication links in a specified manner until the overload condition ceases to exist. More specifically, the PCF receives loading information from each PDSN to which it is connected and determines a composite loading factor. The PCF transmits the composite loading factor to the BSC/ANC periodically or if the loading factor exceeds a specified threshold and call blocking should be initiated for packet data calls for a select group of mobile terminals.

Access control by call type

A method and an apparatus are disclosed for providing the order of transmission of radio link packets of various flows by the outer DSCP markings contained in correlated IDPs. This is achieved by a BSC sorting the IDPs by their associated outer DSCP marking and placing the IDP into a BSC memory as a function of the outer DSCP marking, and then scheduling the IDPs on the basis of in which BSC memory they have been placed.

Method and apparatus to support differential internet data packet treatment in a base station controller

An access network controller and a base station controller are formed to define an interface there between that enables the two systems to facilitate and respond to a voice call that is to be set up to a hybrid mobile station even though the hybrid mobile station is presently engaged in a data only call. More specifically, the base station is formed to generate a pseudo-page signal to the access network controller to determine whether the hybrid mobile station is present and available prior to the base station generating paging signals to establish the voice call. According to the response received from the access network controller, the base station either pages the hybrid mobile station to establish the voice call, forwards the call to voice mail, or forwards the call either to an Internet Call Delivery Server or to an Internet Call-Waiting Server.

Method and apparatus for a hybrid mobile terminal

The present invention is a system for optimizing an existing wireless network and additions to an existing network. The system determines a value representing estimation of traffic in discrete bins within a geographic area. The traffic estimation includes a distribution of handover and new cell traffic based at least in part on the presence of a road in any bin or the proximity of a bin to a handover boundary. The cell coverage and carrier allocations of existing cells are adjusted in view of the traffic estimation.

Automated wireless network design

The frequency transition process migrates frequency groups from one frequency reuse plan to another. In response to a change in capacity requirements, the process migrates each layer of the present frequency reuse plan to the layers of the new frequency reuse plan.

Frequency transition process for capacity enhancement in a cellular

A method for optimizing spectral re-use between an interferer digital phase modulated cellular system and a desirable analog phase modulated cellular system is disclosed wherein an optimal guard band to use with adjacent channel interference is determined, or an optimal guard zone to use with co-channel interference is determined. This is achieved by determining the effect of interference due to a digital phase modulated signal at the baseband of a desired analog phase modulated signal. By the use of this invention, the capacity of a desired system and/or the quality of a service provided by a desired system may be enhanced.
