Abstract: In a wireless communication system, an apparatus and method for managing an uplink communication between a network and a plurality of terminals is achieved by transmitting a response condition parameter from the network to the plurality of terminals subscribing to a multicast service. The parameter is associated with controlling the uplink communication of the plurality of terminals. The terminals then applies the response control parameter to a predetermined test and responds to the network if the terminal determines that it is qualified to respond to the network in response to a result of the predetermined test. The network evaluates whether the parameter needs to be transmitted to the plurality of terminals and whether the parameter needs to be updated based on at least part of responses received by the network.

Abstract: In a UMTS wireless communication system, the enhanced dedicated physical control channel (E-DPCCH) that is usually always transmitted together with the enhanced dedicated physical data channel (E-DPDCH) on the uplink from a UE to a NodeB is instead only transmitted when a predetermined “start criterion” is met and is turned off when a predetermined “stop criterion” is met until a “start criterion” is later met again. The UE starts transmitting E-DPCCH whenever the corresponding E-DPDCH transport format combination is different from the previous one in the same HARQ process or some other “start criterion” is met. Multiple mechanisms can be used to decide when the UE should switch off E-DPCCH transmission after the transport format combination of E-DPDCH has changed.

Abstract: This invention addresses the problem of latency of response regarding information relying on an IMEISV from a CN. This is possible by defining the early RRC connection bits' indication to determine the supported signalling schemes and providing the IMEISV information from the terminal to the network. After this point the CN is able providing this mapping information to the radio access network before actual radio links are utilized. The idea here is for early RRC message information to be used for indicating what version of bitmap correction terminal capabilities refers to and what procedures can be utilized while waiting for this bit map information from the CN. Using this approach the length of the early RRC message can be kept short, the content of corrections can be well defined saving signalling bits, and the concern of a fast available indication on the connection set-up phase can still be addressed.

Abstract: Methods and apparatus related to assignment in a wireless communications system are described. A mobile is assigned an identifier and a mask value, e.g., as part of a state transition message. The mobile uses the assigned identifier and/or the assigned mask value in determining whether assignments included in assignment messages, e.g., traffic channel assignment messages, are directed to the wireless terminal. Predetermined associations between assignment slots, assigned segments, and/or mask values are utilized to limit control signaling overhead. Different groups of segments are available for assignment to different wireless terminals as a function of mask values. Different types of assignment messages use different amounts of information bits to convey the assignment. Some types of assignments use a wireless terminal identifier, while other types of assignments use a wireless terminal identifier and a mask identifier. The mask identifier, e.g.

Abstract: The present invention provides a wireless communication system capable of managing peer-to-peer (P2P) communications. In one embodiment of the invention, upon receiving a request for initiating a call, the system determines whether P2P communication can be established between the two mobile terminals.

If the P2P communication can be established between the two mobile terminals and both mobile terminals are in a default mode for P2P communication, the system establishes P2P communication between the two mobile terminals. On the other hand, if any one of the mobile terminals is in a prompt mode, the system sends a prompt to the mobile terminal in the prompt mode, along with information about incentives for using P2P communication services.

Abstract: The present invention provides a wireless network system for establishing peer-to-peer communication between mobile terminals. Upon determining that peer-to-peer communication can be established between two mobile terminal, the wireless network system transmits to each of the mobile terminals information about radio resources used by the other one of the mobile terminals. Each mobile terminal then uses the radio resources information to test the characteristics of a dedicated uplink channel between the other one of the mobile terminals and the network system. Thus, no separate radio channel needs to be allocated for the channel testing. Furthermore, each mobile terminal uses the same radio resources to establish a dedicated radio channel in the peer-to-peer communication with the other one of the mobile terminals, which were previously used by itself for communication with the network system on the dedicated uplink channel.

Abstract: A multi-hop wireless Ad-Hoc network according to the present invention employs a voice reservation protocol. The protocol supports voice and data communication and incorporates retransmission and acknowledgement mechanisms. A TDMA frame architecture is dynamically selected depending on voice mode operation (e.g., simplex/duplex) and associated retransmission/acknowledgement mechanisms. A source node transmits a reservation packet that embeds TDMA frame architecture and other information. The packet is transmitted to a destination node and is further piggybacked on existing neighbor discovery packets to reduce overhead. Each intermediate network node along the propagation path determines the manner in which to accomplish slot reservation based on the embedded information in the reservation packet. The protocol may use separate dedicated channels or a single channel for voice and data, and supports voice/data load balancing over different channels.

Abstract: A Method and system for transmitting a signaling message between a base station and a mobile station over a half rate channel are shown. Traffic data is interleaved over k bursts diagonally (4 bursts diagonally in GERAN) and a signaling message is interleaved over m bursts diagonally, where m>k. The method includes transmitting the same encoded signaling message in two consecutive radio packets, where each radio packet is interleaved over k bursts diagonally (the consecutive radio packets have an interleaving depth of 6 in GERAN).

The receive side of the communication reads the first packet, stores the soft values for decoding, and soft combines them when the second radio packet is received. Diversity may be added by the transmit side. The re-transmission of the second radio packet is preferably mandatory at call set-up.

Abstract: Two different types of communications channels including first and second types are provided to support user connections in a communications system. A first type of channel supports a user connection. Thereafter, a current load or throughput on the first type of channel is detected. Based on the detected load or throughput, a corresponding data amount threshold is provided. A current amount of data to be transmitted over the user connection is detected. A determination is made whether to switch the user connection from the first type of channel to the second type of channel based on the current amount of data to be transmitted over the user connection and on the data amount threshold. In the example embodiment, the user connection is switched to the second type of channel when the current amount of data to be transmitted is greater than the data amount threshold. Otherwise, the user connection is maintained on the first type of channel.
