The invention provides for the management of wireless resources, which can reduce call blocking by allowing high priority services, under suitable conditions, to use resources allocated to low priority services. Thus high priority services can pre-empt the usage of wireless resources by low priority services. This has the advantage of reducing call blocking for high priority calls, while permitting low priority calls to have more access to radio resources than conventional systems with the same call blocking rate. Thus a base station can implement a preemption mechanism that would reclaim Walsh Code and Forward Power resources from an active Supplemental Channel (SCH) burst in order to accommodate incoming Fundamental Channel (FCH) requests.

A method for managing access to service entities (e.g., such as a devices, resources, and services, which are limited resources) is provided. The method includes requesting a priority level. In response, a priority object with an assigned priority level is returned. A service is then requested from a service manager, and the request includes data for carrying out the requested service and the priority object. The service manager is configured to identify at least one service entity that is required to carry out the requested service. Access is then requested to at least one service entity. A determination is made as to whether the at least one service entity is in-use. If at least one service entity is in-use, a further determination is made as to whether at least one service entity that is in-use has an assigned priority level that is higher than the assigned priority level, which is associated with a current request. The requester, such as a carlet, which has the higher assigned priority will gain control of the requested entity.

A system and method of providing high speed, prioritized delivery of data packets over broadband communications networks that avoids inducing unwanted latency in data packet transmission. The system employs a hierarchical, real-time, weighted token bucket prioritization scheme that provides for fair sharing of the available network bandwidth. At least one token bucket is employed at each level of the hierarchy to meter data flows providing service applications included in multiple subscribers' service plans. Each token bucket passes, discards, or marks as being eligible for subsequent discarding data packets contained in the data flows using an algorithm that takes into account the priority of the data packets, including strict high, strict medium, and strict low priorities corresponding to strict priority levels that cannot be overridden. The algorithm also takes into account weighted priorities of at least a subset of the low priority data packets. The priority levels of these low priority data packets are weighted to provide for fair sharing of the available network bandwidth among the low priority data flows, and to assure that none of the low priority data flows is starved of service.

If yes, the method additionally admitting the traffic flow, storing information associated with the traffic flow in the queue, and transmitting information associated with the traffic flow from the queue based on at least a strict priority process. If the queue corresponds to the one of a second plurality of priority levels, the method further admitting the traffic flow, storing information associated with the traffic flow in the queue, and transmitting information associated with the traffic flow from the queue based on at least an arbitrated priority process.

A method for access assurance in a wireless communication system, e.g., a mobile phone network, involves allocating communication resources for transactions between the network and various wireless access terminals (each having a unique identifier) based on priority classes assigned to the access terminals. The access terminals are divided into different priority classes based on public policy and similar considerations. Each access terminal's priority class is associated with its identifier in a database. Upon communicating with an access terminal, the network determines the access terminal's priority class based upon its identifier as received by the network, e.g., the identifier is correlated to the priority class in the database. Transaction priority levels are then calculated based on each access terminal's priority class. Air interface resources are allocated according to the computed transaction priority levels and one or more pre-determined allocation precedence rules governing priority.

The present invention relates to wireless telephone networks, and more particularly to the allocation of radio channels to calls in CDMA-based systems when their Radio Access Networks (RAN) are congested. A Base Station (BS) receives a call origination from a mobile device. The BS communicates information about the call and about its radio availability to a Mobile Switching Center (MSC). The MSC determines the priority of the call and how the call should be treated by the BS based on the supplied information. The MSC communicates the treatment information and the priority information back to the BS.When the RAN is congested, high-priority calls are queued. These high-priority calls are served based on allocation specification in which radio channels may be assigned to low-priority calls, which are not queued, while there are still calls in the queue.

A method for delivering a priority call waiting alert service to a telephone subscriber. An embodiment of the present invention may be implemented on an Advanced Intelligent Network (AIN). When a call intended the subscriber is received by a service switching point from a calling party while the telephone line is already engaged in a first communication between the subscriber and a third party, the calling party is solicited to supply a priority code. If the priority code is recognized by a service control point, a call waiting tone or a priority alert signal associated with the priority code is played to alert the subscriber that a priority call has been received.

A mobile communications system has a radio network controller and a Node B coupled to the radio network controller, the Node B being operable to control a plurality of its Node B internal resources for admission control. Admission control is moved from a controlling radio network controller (CRNC) to the Node B so as to avoid possible errors relating to fragmentation that occur in systems in which the CRNC controls admission. To support network related requirements, such as reserving capacity for high priority calls and incoming handovers, the CRNC informs the Node B about the reservations that shall be applied, and the Node B configures the admission control algorithm in accordance with the reservations.

The processing then continues by performing at least a portion of the atomic sequence when the comparing of the sensed priority level with the corresponding priority level is favorable.

The embodiment of the invention discloses a data transmission method which comprises the following steps: nodes in the network transmit guaranteed time slot (GTS) requests to a coordinator. The coordinator distributes GTS for the node according to the priority levels of the to-be-transmitted data in the received node GTS requests. The nodes transmit data in the distributed GTS. If the coordinator receives the GTS requests from nodes of high-level priority, the GTS distributed for current nodes of low-level priority can be reduced or stopped and distributes the GTS to the nodes of high-level priority, thus guaranteeing important information in the network can be transmitted preferentially. The embodiment of the invention also discloses a data transmission system as well as a node device and a coordinating device. By application of the system and devices, important information in the network can be transmitted preferentially and thus network service quality (QoS) service can be provided partially.

The present invention relates to a method, terminal device, network element, authentication server, and computer-readable medium for controlling prioritized access to a wireless access network. An identifier portion in an authentication response is set to a service-specific unique default identifier portion, dedicated to a predetermined prioritized call, at a terminal device, when the predetermined prioritized call is activated. The authentication response is forwarded to a predetermined default authentication server where a predetermined default service-specific authentication method is initiated for authorizing the terminal device to access the predetermined prioritized service. Thereby, emergency calls or services are made by terminal devices without SIM or USIM, and no new authentication functionality related to prioritized calls is required due to the transparent character of the service-specific unique default identifier portion.

The present invention relates generally to the field of telecommunications and more particularly to a method of and system for organizing, prioritizing and placing a user's outgoing telephone calls. One embodiment of the invention allows a user to generate an electronic list of telephone calls to be made, the ordering of entries being made by priority level, higher priority entries being placed higher on the list than lower priority entries. The user simply requests that the next highest priority call in the list be made, and the method and system identifies the telephone number for the next party on the sorted list and places the call. Thus, the user can step through his list of calls without having to locate telephone numbers or waste time dealing with unimportant calls. Other embodiments allow the user to determine whether a potential callee is available, or willing to accept his call.

A data processing apparatus and method for setting priority levels for transactions is provided. The data processing apparatus has a shared resource for processing transactions, and at least one master device for issuing the transactions to the shared resource. The at least one master device provides a plurality of sources of the transactions, and each of the transactions has a priority level associated therewith. Arbitration circuitry is used to apply an arbitration policy to select a transaction from amongst multiple transactions issued to the shared resource, the arbitration policy using the priority level associated with each of the multiple transactions when performing the selection. Adaptive priority circuitry is associated with at least one of the sources, the adaptive priority circuitry monitoring throughput indication data for previously issued transactions from the associated source, and for each new transaction from the associated source, setting the priority level to one of a plurality of predetermined priority levels dependent on the throughput indication data. Through such a mechanism, the adaptive priority circuitry sets the lowest priority level from amongst the plurality of predetermined priority levels that will enable a specified target throughput to be achieved. The adaptive priority circuitry hence uses a feedback mechanism to control the priority level assigned to each new transaction from a source in order to target a specified throughput for the source, and through this mechanism finds the lowest priority necessary to achieve the throughput objectives independent of the activity of other sources within the system.

The present invention relates to wireless telephone networks, and more particularly to the allocation of radio channels to calls in CDMA-based systems when their Radio Access Networks (RAN) are congested. A Base Station (BS) receives a call origination from a mobile device. The BS communicates information about the call and about its radio availability to a Mobile Switching Center (MSC). The MSC determines the priority of the call and how the call should be treated by the BS based on the supplied information. The MSC communicates the treatment information and the priority information back to the BS. When the RAN is congested, high-priority calls are queued. These high-priority calls are served based on allocation specification in which radio channels may be assigned to low-priority calls, which are not queued, while there are still calls in the queue.

An apparatus and a method for performing data transfer that can ensure QoS of data transmitted and received are provided. IEEE802.1p priority tags as priority identifiers are set under control of a tag managing terminal. A priority tag is set for a data flow to be subjected to priority processing, for example, to be guaranteed QoS so as to prevent duplicate use of a queue in a communication control apparatus such as a switch or the like connected to a network. The tag managing terminal for example converts a queue use state in intra-subnetwork communication into a table, and retains the table. In response to a queue request from each terminal, the tag managing terminal refers to the table and then assigns a tag. The communication control apparatus such as the switch or the like that executes data transfer control prevents duplicate queue generation for data flows to be subjected to priority processing only by processing using the priority table associating tags with queues.

A deficit fair priority queue scheduling technique includes arranging connections in a waiting queue according to a plurality of priority classes including a first class having a higher priority than a second class. Each time a scheduler visits a queue having waiting connections, a deficit value for each priority class is initialized and used to determine how many bandwidth request packets for that class will be serviced in a round. The highest priority packets will be serviced until the deficit value for that class falls below a selected threshold or there are no remaining waiting packets of that class. Within the same round, the scheduler can service lower priority connections until the deficit value for that service class is below the threshold or there are no remaining packets of that class. Because the lower class packets have a chance of being serviced before all higher priority class packets have been serviced, the disclosed example is a deficit fair priority queuing technique.

In a wireless communication system, slave units such as operation switches and the like are configured such that the higher the priority level of an information signal to be transmitted from each slave unit is, the shorter a period t1 of a carrier sense to be performed before the transmission is set. Therefore, when the slave units attempt to transmit information signals of different priority levels by using the same time slot, one of the slave units whose information signal to be transmitted is of the highest priority level is given the shortest carrier sense period t1 before the transmission of the information signal, and therefore, can transmit the information signal at the earliest timing. Accordingly, by causing the slave unit which becomes able to transmit the information signal at the earliest timing to transmit the information signal, the information signal of the highest priority level can be transmitted at the earliest timing, while the other units are caused to sense, by carrier sense, the transmission, and put off transmission of their own information signals.

A network node is configured to negotiate for connections for high priority calls (e.g., voice calls) received at the node in the face of otherwise congested outbound communication links. The negotiation is conducted in a fashion that will preserve connections for existing calls associated with the node. For example, the negotiation may be conducted so as to cause one or more of the existing calls to consume less bandwidth over the outbound communication links than was consumed at a time prior to reception of the high priority calls. Such negotiations may be initiated depending on the availability of codec resources and / or compression schemes at the node and may be conducted using OAM cells.

A system and method for permitting communication with a supervised wireless device upon which incoming call restrictions have been placed in the event an emergency service provider attempts to communicate with the supervised wireless device. The emergency service provider, such as a 911 call center, can communicate with a supervised wireless device once incoming call restrictions on the wireless device are disabled. The incoming call restrictions on the supervised wireless device may be disabled during a time interval or until a specific event occurs. The time interval may be resetable, and the event may be an indication of a priority call from an emergency service provider. The disabled restriction may include all restrictions, or a subset of restrictions, such as time of day or incoming call ID restrictions. Calls placed to or received from the emergency service provider may be in the form of voice communications, SMS, MMS, IM, email messages or any other available form. The disabled restrictions may be based on the type or form of the call to the emergency service provider.
