摘要:
A resource allocation algorithm identifies a resource hogger in a wireless communication system data sharing arrangement and control shared resource overuse by the resource hogger. In one embodiment, the base station for a given sector in the system tracks the time-slot usage of each active user in the sector. If the usage for any user reaches a predetermined hogger threshold, normal target QoS enforcement is suspended for that user to allow more time slots to be allocated to the other, non-hogger users. When the resource hogger user's usage falls below the threshold, target QoS enforcement is returned to that user. Temporarily suspending target QoS enforcement for resource hoggers and allocating the remaining resources to other users prevents resource hoggers from deteriorating performance of the entire system.

At least a portion of a total spectrum bandwidth of a wireless system may be allocated to each of a plurality of users by assigning at least one unique spreading code to each of the plurality of users. At least two of the plurality of users may have different spectrum capabilities and may transmit simultaneously. Each of the assigned spreading codes may have a different code length. The number and/or the code length of the spreading codes assigned to each user may be indicative of a portion of the total spectrum bandwidth allocated to each user.

In one embodiment a first comparison result is determined based on a link quality metric and a first threshold value. Based on the first comparison result, a second base station is selected, and the mobile device is instructed to switch from communicating wirelessly with the first base station to communicating wirelessly with the second base station

In one aspect of the instant invention, a method is provided for controlling a communications system in which VoIP traffic and data traffic are both provided. The method comprises receiving voice over internet protocol packets, accumulating a plurality of the voice over internet protocol packets, and transmitting the accumulated plurality of voice over internet protocol packets within a single time slot.

The present invention provides a method and an apparatus for a wireless communication between a base station and at least one mobile station. The method includes receiving a request for a data rate from the mobile station on a reverse link channel to the base station. The method further includes, in response to the request, skipping a first slot after a delay for a portion of a slot on a forward link transmission before transmitting a data packet in a second slot. By beginning the forward link transmission at the start of the second slot, for example, a software module may cause the base station to skip a slot immediately after the half slot delay. This additional delay of one slot or a portion of the slot may expand radius of a cell for a wireless communication between the base station and the mobile station in a relatively high-speed wireless data network.

A wireless data network distinguishes among different users connected to the network and associates each user with a service class that offers a selected level of service. The base station in the network queries the user for its unique user identification code and accesses a database linking user identification codes with their corresponding services classes. The network then controls the service level given to that user based on the service class associated with the user identification code. The user identification code can be sent to the network via existing fields in current standards.

The present invention provides a method for controlling mobile unit response messages. One embodiment of the method includes providing, to a mobile unit, at least one message including information indicative of at least one parameter for configuring at least one response to said at least one message for transmission over an access channel.

The present invention provides a method and an apparatus for controlling a radio frequency resource between a first and a second wireless unit and a base station to provide overload control of the radio frequency resource based on an estimate thereof. For example, when feedback information is unavailable for the radio frequency resource at the base station. The method includes estimating the radio frequency resource used by the first and second wireless units in a wireless data network. The method further includes providing an overload control at the base station based on the estimated radio frequency resource. Based on this estimated radio frequency resource, a command may be issued by the base station on a reverse link. For example, a rise over thermal resource may be estimated to issue a rate control command to a wireless unit. By providing a desired timely rate control command on the reverse link, the base station may control a data rate of the wireless unit, maximizing throughput of the reverse link. In this way, a base station may control a rise over thermal resource metric to relieve an overload condition at the base station in a relatively high-speed wireless data network.

The present invention provides a method and an apparatus for enabling at least one location-based service between an originating party and a destination party on a wireless network. The method comprises integrating access to the at least one location-based service substantially simultaneously with an offering of at least one multi-media service for voice and data over the wireless network. The method further comprises initiating the at least one location-based service in response to receiving an inquiry from the originating party for determining a network location of a target mobile terminal associated with the destination party. A service platform may generate substantially simultaneously multi-media services including a location-based service based on location information of a destination user in a wireless network, such as a mobile data network.
