摘要:
The present invention provides methods of inter-technology handoff of a multi-mode mobile unit in a packet-switched communication system. One embodiment of the method includes establishing a call from a first application layer client in the first mobile unit using a first wireless communication link that operates according to a first wireless access technology. The method also includes sending, in response to detecting changing conditions of the first wireless communication link, a request to form a conference call including the first application layer client and inviting a second application layer client in the first mobile unit to join the conference call. The second application layer client uses a second wireless communication link that operates according to a second wireless access technology. The method further includes handing off the call from the first application layer client to the second application layer client.

The present invention provides a method of best effort hand off that is implemented in a mobile unit capable of communicating with a network according to multiple wireless access technologies. The method includes performing a handoff of the mobile unit from a first wireless communication link established according to a first wireless access technology to a second wireless communication link established according to a second wireless access technology. The method also includes transmitting, over the second wireless communication link, a de-registration message requesting de-registration of the first wireless communication link in response to performing the handoff.

A method for determining rise over thermal for a base station in a wireless communications system is provided. The method comprises receiving a first and second diversity signal, measuring the signal strength of the first and second diversity signals, and estimating the noise floor for the first and second diversity signals. The signal strength rise is determined for the first and second diversity signals based on the measured signal strength and estimated noise floor of the first and second diversity signals respectively. The rise over thermal is then determined based on the determined signal strength rise of the first and second diversity signals.
摘要:
The present invention provides a method for dynamically estimating noise floor by continuously updating a noise floor value based on the noise floor value and sampled receive strength indications. In an alternative, the noise floor may be updated based on sampled receive strength indications and the reverse link loading value. In yet another alternative, the noise floor may be updated based on sampled receive strength indications and a range relative to a reference noise floor value.
摘要:
A method and an apparatus for maintaining a quality of service (QoS) for a multi-media packet data service in a transport network is provided. The method comprises determining a first packet loss indication for a first flow of QoS traffic packets. The method further comprises determining a second packet loss indication for a second flow of QoS traffic packets, wherein the determination of the first packet loss indication for the first flow of QoS traffic packets is independent from the determination of the second packet loss indication for the second flow of QoS traffic packets. The method further comprises determining whether to drop the first flow of QoS traffic packets based on the first packet loss indication or to drop the second flow of QoS traffic packets based on the second packet loss indication. By using per-flow independent packet loss statistics to determine whether that flow should be dropped and gradually dropping such QoS flows having the most impact on a desired QoS performance, a reduced number of QoS flows may be dropped to recover a data transport network from congestion.
摘要:
For handover between wireless telecommunications networks of different technology types, an air interface is set up between a first node 4 included in a network of a first technology type and a second node 10 included in a network of a second different technology type. Signaling messaging, in accordance with the second technology type, is related to handover of a mobile terminal from the network of the first technology type to the network of the second technology type. The signaling messaging is encapsulated in a container for transmission over the signaling interface. An identifier is associated with the container to indicate that it encapsulates the signaling messaging. When the identifier is detected at the first node, the container is sent over the interface to the second node. In one method in accordance with the invention, the first technology type is WiMAX and the identifier is a special service flow identifier. This may be detected at an Access Services Network Gateway (ASN GW), for example. A method in accordance with the invention thus permits the use of logical radio channels for encapsulating inter-technology signaling.
