A service processing method, a service processing system, and a PCRF entity are disclosed to overcome this defect in the prior art: The prior art is unable to handle services discriminatively according to the policy context information when different services require the same QoS level The method includes: receiving bearer priority information from a PCRF entity, where the bearer priority information includes: bearer priority information of a service data stream, bearer priority information of an IP-CAN session, and/or bearer priority information of an IP-CAN bearer; and handling services according to the bearer priority information In the embodiments of the present invention, the policy context information is converted into bearer priority information so that the PCEF handles services according to the bearer priority information In this way, different services that require the same QoS level are handled discriminatively according to the policy context information

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

Method and system of managing wireless resources

A method for specifying the quality of service in a transmission of data packets between a service entity (AF1) and a user equipment over a mobile network is described. The mobile network comprises a core network node (SGSN1) and an access node (NB1, RNC1) which are adapted to control the handling of data packets sent between the service entity (AF1) and the user equipment (UE1). A plurality of service classes relating to the quality of service are preconfigured and a selected service class is selected from said plurality for the transmission. A first transmission context (PDP1) is established between the core network node and the user equipment (UE1), said first transmission context being associated with a first set of attributes for defining a first quality of service for the exchange of the data packets with the user equipment in the transmission. Furthermore, a second transmission context (RAB1, RB1) is established between the access node (NB1, RNC1) and the user equipment (UE1), said second transmission context being associated with a second set of attributes for defining a second quality of service for the exchange of the data packets with the user equipment in the transmission. The selected service class determines the first set of attributes by a first unique mapping function performed in the core network node and the selected service class determines the second set of attributes by a second unique mapping function performed in the access node. A corresponding mobile network, control device and computer program are also described.

Method and devices for specifying the quality of service in a transmission of data packets

A computer system that provides services to clients may adaptively throttle incoming service requests in order to reach and then maintain operation at an ideal request rate. An ideal request rate may be a maximum rate at which incoming service requests can be serviced such that client-specified quality of service (QoS) expectations are met for most or all incoming service requests, or a rate within a range of rates defined by that maximum rate. Determining whether the system is operating at an ideal request rate may include determining the minimum difference between the expected and actual QoS for a group of recently serviced requests. The system may gradually modify a throttle multiplier value in order to reach or maintain an ideal request rate. Maintaining operation at an ideal request rate may allow the system to avoid entering an overloaded state, and/or oscillating between an overloaded state and a non-overloaded state.

System and method for avoiding system overload by maintaining an ideal request rate

Directing a video player to a video source is disclosed. An indication that a client requires video streaming instructions is received. A past download performance for a plurality of clients that or correlated to the client requiring video streaming instructions is determined. At least one of: a content source, and a bitrate, is selected, based at least in part on the determined past download performance of the plurality of correlated clients. The client is provided with instructions based at least in part on the selection.

Source assignment based on network partitioning

The invention relates to a method for managing the quality of service that applies to a packet mode mobile communications network, in particular, characterised in that it includes, in the case of a network overload when accessing the resources of the network in order to execute a service for a network subscriber, a stage that consists in the following, at the level of each of the network nodes: determining an overall priority level for said access to resources, defined by a combination of at least one quality of service parameter related to the type of service and at least one quality of service parameter corresponding to the subscriber priority level, and applying at least one predefined quality of service process to the data stream that corresponds to said service, according to said determined overall priority level.

Method for quality of service differentiation in packet-mode mobile communication networks

The method involves determining a total priority level for access to network resources at the level of nodes (BSS/RNC, SGSN, GGSN) of a mobile communication network. The priority level is defined by a combination of service quality parameters related to a type of service with service quality parameters related to a priority level of a subscriber. A predefined service quality process is applied to a data flow. The data flow corresponds to the service based on the level of determined total priority. The determination process and the quality process application process are performed based on network overload at the time of access to the resources.
