Efficient bandwidth allocation for high speed wireless data transmission system
InactiveUS6693915B1Time-division multiplexData switching by path configurationData fieldWireless data transmission
The invention relates to a method in a wireless data transmission system (1) which comprises wireless terminals (MT1-MT4), at least a first access point (AP1) and a first access point controller (AC1), a second access point (AP2) and a second access point controller (AC2). In the data transmission, data frames are used. In the invention, two allocation strategies are defined of which two are selected at a time. From the data frames, a first starting point (TS11, TS21) and a second starting point (TS1n, TS2n) are determined. In order to select a strategy, it is examined whether there is other traffic on the channel. If other traffic can be detected, it is examined which allocation strategy is selected, and an allocation strategy which is different from that of the examined connection is selected for the connection to be set up. However, if traffic is not detected, it is possible to select the allocation strategy freely. In the first allocation strategy, the allocation of the time slots of the data field (D1, D2) is started from the first starting point (TS11, TS21) of the data field, and in the second allocation strategy, the allocation of the time slots of the data field is started from the second starting point (TS1n, TS2n) of the data field.

Method and apparatus for network wide adaptive resource allocation for OFDMA/TDMA networks
ActiveUS20090080375A1Network traffic/resource managementWireless commuication servicesSelf adaptiveResource allocation
In this invention, adaptive resource allocation is proposed. A resource is divided into Blocks and each base station is assigned a Block for its terminals that are in the interference region, and another Block for its terminals that are not in the interference region. Blocks other than these two are not used by the base station. Bordering base stations does not use the same Block if they have any terminal in the shared interference region.Another embodiment of the invention proposes resource sizing along with load balancing scheme. Resource sizing is defined as determining the size of the resources allocated for each Block. This is adaptable and can change over time according to topology. Another embodiment of the invention proposes a handover method for some terminals in order to increase the Block utilization by handing a terminal over another base station. Final embodiment of the invention proposes an adaptive control scheme that defines multiple policies for different topologies. Selecting a policy is determined by the given topology as well as the output utilization where utilization is defined as the allocated resource over total resource per Block together with demanded resource over total resource per Block.

A system and method for the implementation of fine-grained quality of service in a mobile telecommunications environment uses an Auto-IP Policy Decision Point (PDP) to determine what traffic optimizations actions should be taken in reaction to various network conditions. The Auto-IP PDP uses as inputs information from a Gb interface probe to determine the user identification of an IP data flow, information from the radio access network (RAN) network management system (NMS) regarding network congestion. The cell traffic information is passed onto a traffic analysis and processing engine, the Auto-IP PDP which maps the real-time traffic information into an n-dimensional traffic model. An automated policy decision guiding algorithm is executed on the n-dimensional traffic model and selects policy based on the traffic and cell congestion conditions, without human intervention. Additionally, a consistency check is performed to ensure that new policies are consistent with existing policies. The policy decision outcome is forwarded to the Auto-IP Traffic Optimizer that acts on the network at a point in the network (Gi) that is different from where traffic problem occurs in the RAN. The Auto-IP Traffic Optimizer implements the decisions of the Auto IP-PDP by performing traffic shaping, TCP window clamping or other traffic optimization procedures on a cell-by-cell basis.
