Abstract: A set of piconets and corresponding methods and computer programs may reduce contention time between piconets. In one embodiment, a seven-length code architecture may be used with group(s) of bands so that contention time cannot exceed 1/7 of the time. Up to seven different bands can be used within each group. When less than seven bands are used (e.g., three or six), at least one of the bands may be assigned to more than one dwell time during a time span. Alternatively, each dwell time within the time span may be assigned to a different band. The state may be changed as needed or desired. Substitution of extra bands may also be used. Using either scheme (repeated bands or changing states), a prime-number architecture can be used with a non-prime number of different bands. Simultaneous communications using at least two bands within a piconet may be used.

Abstract: A communication system provides a Multimedia Broadcast/Multicast Service (MBMS) to a roaming user equipment (UE) by receiving, at a first network, a request from the UE to subscribe to an MBMS service and, in response to receiving the request, conveying to the UE a Temporary Mobile Group Identity (TMGI) that is uniquely associated with the MBMS service and the first network. When the first network receives information associated with a registration of the UE with a second network and further receives MBMS data associated with the MBMS service, the first network conveys the MBMS data and the TMGI to the UE via the second network. By using a TMGI that is unique to the MBMS service and the first network, the UEs subscribed to an MBMS service at the second network ignore a notification conveyed to the UE by the second network, thereby preserving a battery life of such UEs.

Abstract: In many cellular systems, reusing spectrum bandwidth, creates problems in boundary regions between the cells and sectors where the signal strength received from adjacent base stations or adjacent sector transmissions of a single base station may be nearly equivalent. The invention creates a new type of diversity, referred to as multiple carrier diversity by utilizing multiple carriers, assigning different power levels to each carrier frequency at each base station, and/or offsetting sector antennas. The cell and/or sector coverage areas can be set so as to minimize or eliminate overlap between cell and/or sector boundary regions of different carrier frequencies. Mobile nodes traveling throughout the system can exploit multiple carrier diversity by detecting carriers and selecting to use a non-boundary carrier based on other system criteria in order to improve performance. Boundary carriers may, but need not be, identified and excluded from consideration for use by a wireless terminal.

When the UE is located in a non-soft handover region in a region of the Node B, it transmits uplink data to the Node B for a predetermined first transmission time interval.

Abstract: Shared network area (SNA) information is distributed using indicators that represent the SNA information. First SNA information for a first group of first network mobile subscribers is mapped to a first SNA indicator. Similarly, (SNA) information for a second group of second network mobile subscribers is mapped to the second SNA indicator. Those mappings are established in a core network node and sent to radio network nodes and used to determine from the SNA mappings the network access restrictions for a subscriber. The network access restriction information is not sent—only the indicator. The indicator is used to ensure that the cell selected to establish a call connection or for a handover is permitted based on the SNA information.

Abstract: In a mobile telecommunications system, when it is determined that a mobile terminal should be handed over from a first cell (primary cell) to a second cell (target cell), the target cell is chosen based on measurements of link quality in the primary network at the time when it is determined that handover is necessary, as well as on stored data indicative of the respective probabilities that different potential target cells will be the best handover target from a particular primary cell. This enables an appropriate choice of target cell to be made even in a case where it is not possible to make measurements on the target cells at the time when it is determined that handover is necessary (for example because handover is to a target cell that operates at a different frequency from that of the primary cell).

Abstract: The present invention relates to a method and apparatus for controlling a connection transfer in a cellular network having at least two systems, such as a GSM system and a WCDMA system. Based on a load determination, a service-based inter-system or inter-frequency handover of the connection to another system or to another carrier of the same system is initiated if the determined is below a threshold and service priorities are indicating it. If it exceeds the threshold, an additional load-based inter-system or inter-frequency handover can be initiated. If the load of the target cell is not known, a load estimation based on a learning process can be used to derive a probability of success of an interfrequency or inter-system handover, which may be used for deciding on the initiation of the inter-system handover. The learning process may be performed by evaluating preceding interfrequency or inter-system handovers to the target cell or preceding interfrequency or inter-system handovers from the target cell.

Abstract: Load redistribution and other benefits may be achieved by dynamically distributing or “steering” idle mobile stations to a particular cell or area. For example, idle mobile stations may be steered from a loaded cell to less loaded cells by changing one or more cell broadcast parameters.

Also, the time frames allocated for communication along the channels that experience interferences are divided into at least two time sub-frames.

Abstract: The number of measurements being performed in a telecommunications system can be reduced by performing a predetermined measurement in Cell A and in co-located Cell B, step 1, for example a received signal code power (RSCP) measurement. The difference between the two signals is determined, and stored for future reference, step 3. Once the difference value has been established, the mobile station no longer needs to perform measurements on both Cell A and Cell B. Instead, if a subsequent measurement is made on Cell A, step 5, the network can estimate the measurement for Cell B based on the difference signal previously determined, step 7.
