Techniques to implement MBMS services in a wireless communication system. In one aspect, a method is provided for processing data for transmission to a plurality of terminals. Frames of information bits (which may have variable rates) are provided to a buffer implementing a matrix. The matrix is padded with padding bits based on a particular padding scheme to support variable frame rates. The frames are then coded based on a particular block code to provide parity bits. The frame of information bits and the parity bits are then transmitted to the terminals. In another aspect, a method is provided for controlling the transmit power of a data transmission to a plurality of terminals. In accordance with the method, TPC streams are received from the terminals and processed to obtain a stream of joint power control commands used to adjust the transmit power of the data transmission.

Multi-media broadcast and multicast service (MBMS) in a wireless communication system

Different types of traffic requiring different inactivity timer settings are assigned to different bearers or to different QoS classes. Different inactivity timer settings are established for different traffic types. Individual bearers or individual QoS classes are linked to a corresponding inactivity timer profile. The link may be accomplished in a number of ways. For example, an additional QoS parameter may be employed in a 3GPP QoS profile, or a new QoS class identifier may be mapped to an inactivity timer setting. Different inactivity timer settings allows both UE battery power conservation to be prioritized for some traffic and end-user experience (quick subsequent response times) to be prioritized for other traffic.

A conference call facility is described in which one (2a) of a group of communication devices (2a,2b,2c,2d) connected to a low power radio frequency network (9) is able to set up a call to a party external of the network (9) and then selectively add further devices (2a,2b,2c) to the call under the control of the user of the one device (2a) The users of the other devices (2b,2c) are able to enable or disable the selection of their device in a conference call One or more of the communication devices may be a mobile radio telephone equipped with the necessary network interface (1)

Conference call method and apparatus therefor

Disclosed is a method and system for dynamically selecting a communication channel between an access point (AP) and a plurality of stations (STAs) in an IEEE 802.11 wireless local area network (WLAN). The method includes the steps of: determining whether a new channel to be used by the plurality of STAs is needed; measuring the channel quality of a plurality of frequency channels by at least one of the plurality of STAs; reporting the quality of the plurality of frequency channels in terms of a received signal strength indication (RSSI), Clear Channel Assessment (CCA) busy periods and periodicity; and, selecting one of the candidate channels based on the channel quality report for use in communication between the AP and the plurality of STAs.

A mobile computer system capable of seamless roaming between wireless communication networks includes data processing resources for executing software, a plurality of wireless interfaces that supports simultaneous wireless connections with first and second wireless communication networks, and a network access arbitrator that routes data communicated between the software executed by the data processing resources and the first and second wireless communication networks. To permit seamless roaming, the network access arbitrator routes the data to the first wireless communication network via a first wireless interface and then seamlessly reroutes the data to a second wireless communication network via a second wireless interface. According to one embodiment, the network access arbitrator reroutes the data in response to the data bandwidths of the connections with the first and second wireless communication networks.

Systems and methods according to these exemplary embodiments provide for handing off user equipment between different access networks, e.g., a high rate packet data (HRPD) system and a long term evolution (LTE) system. An existing mobile IP session can be maintained by the UE during the handoff.

Inter-system handoffs in multi-access environments

A wireless communication network manages communication resources based on the types of packet data being carried by the network for each mobile station. Packet data for each use is matched to packet matching filters in defined flow type profiles. Each flow type profile corresponds to an expected application behavior and includes one or more resource control parameters having values set with regard to that expected behavior. An application activity profile is generated for each mobile station based on deriving resource control parameters using parameter values corresponding to the active flows for each mobile station. The network determines each mobile station's active flows based on matching that mobile station's packet data types to one or more of the defined flow type profiles. Thus, the network manages communication resources individually and/or jointly for its users based on the type of packet data traffic passing through the network for each of those users.

The present invention relates to an arrangement for interconnecting a first communication system and a second communication system wherein the second communication system is a cordless access system. The first communication system is a cellular mobile communication system and the interconnecting arrangement comprises an interworking function (IWF) which via an existing interface of the first communication system is connected to a Mobile Switching Centre of the first communication system and which via an interface of the second communication system is connected to an access system of the second communication system. The invention also relates to an interconnected system comprising a first and a second communication system wherein the first communication system is a cellular mobile communication system and the second system a cordless access communication system wherein the systems are interconnected via an interworking function (IWF).

A method is presented for address resolution mapping in a wireless multihop communication network wherein the network is built up by client devices and/or infrastructure devices, network traffic is based on using ARP forwarding and rebroadcasting to locate devices in such a network architecture. The invention also includes devices for such a network and the complete communication system is described.

Method, communication device and system for address resolution mapping in a wireless multihop ad hoc network.

The present invention provides a method and system for quickly deallocating packet traffic channels. According to exemplary embodiments of the present invention, the capability of performing point-to-multipoint communications is provided on the PTCH by defining a multicast address that all mobiles read. Through the use of a multicast address, a plurality of mobile stations can simultaneously be notified of the termination of PTCH services. As a result, the network can reallocate PTCH resources in a minimum amount of time.
