Abstract: A method for subscriber station-based admission control may include determining that there is demand for a new connection at the subscriber station. The method may also include determining whether the new connection should be admitted based on resource availability. The method may also include sending a request for the new connection to a base station if it is determined that the new connection should be admitted.

Abstract: A method for allocating polling bandwidth may include generating polling tokens corresponding to connections maintained by a base station. The polling tokens may be generated at configurable time intervals. The method may also include assigning priorities to the polling tokens. The priority of a polling token may depend on a scheduling type of a corresponding connection. The method may also include allocating polling bandwidth to the connections that correspond to the highest priority polling tokens when uplink bandwidth is available to allocate for polling.

Abstract: A method and apparatus for performing an inter-system soft handoff is described. In accordance with the present invention, when a subscriber unit crosses from a first cellular system to a second cellular system, a base station controller determines if sufficient network resources are available to conduct a inter-system soft handoff. If so, the base station controller generates a set of signaling messages that cause call processing resource to be allocated and for the call to be processed at the second cellular system. The base station controller then perform data-selection and data-broadcast for the call by transmitting data to the subscriber unit by way of the second cellular system as well as via one or more base stations to which the base station controller is directly coupled. The determination as to whether sufficient network resources are available to conduct the inter-system soft handoff is based on the type of connection that exists between the first cellular system and the second cellular system, the number of inter-system calls being conducted, and the frame offset of the call currently being processed.

Abstract: A method and apparatus for operating a cellular telephone system that supports performing an inter-system soft handoff is described. A subscriber unit generates a pilot strength measurement report when the pilot channel from a base station is detected. When a base station controller receiving the pilot strength measurement report determines that the base station is part of a second cellular telephone system, a inter-system soft handoff request is generated. An admission control subsystem receives the inter-system soft handoff and either grants or denies the request base on the traffic level with the second cellular telephone system. In a preferred embodiment of the invention, the traffic level is determined based on link load messages received periodically by the admission control subsystem that are generated by an interface port coupled to an interconnect between the first cellular telephone system and the second cellular telephone system. The link load message include peak queue length and average frame rate information.

Abstract: A loopback processing method includes detecting a loopback at a first entity in a wide area network. The detection is accomplished by recognizing that a "memorized" frame has returned on the same communications interface within a given period of time. The time interval between sending the frame and detecting it returning at the same port may be recorded and sent to an operator to provide information on the relative location of the loopback in the network. A loopback detect sequence is sent from the first entity to a second entity on the communications interface in loopback. Because of the loopback, both entities receive the loopback detect sequence.

Abstract: A method, an apparatus, and a computer program product for wireless communication are provided. The apparatus receives a service through an MBMS session. The apparatus receives a first notification of an upcoming suspension of the MBMS session. The apparatus requests establishment of a unicast bearer prior to the upcoming suspension of the MBMS session upon receiving the first notification. The apparatus receives a corresponding unicast version of the service of the MBMS session via unicast when the unicast bearer is established. In an aspect, the first notification may be received during a first MCCH modification period, the corresponding unicast version of the service is received via unicast during a second MCCH modification period. In an aspect, the apparatus may further receive a second notification that the MBMS session is suspended during the second MCCH modification period.
