Abstract

A radio link service profile is defined as a set of parameters for upper layer transport of an IP packet, and may be associated with a logical channel flow identifier. A data packet is sent over a wireless logical channel that is identified by the LCID between a base station and a user equipment. The association of RLSP, whether created or invoked form a memory, is coordinated among the BS and the UE without the need to involve the radio network controller, and if the RLSP does not have a diffserv field on the uplink, the BS adds it prior to forwarding the data packet. A method, device (both BS and UE), computer program product, and system are described in multiple embodiments.

Description

technical field

[0001] The exemplary, non-limiting embodiments of the present invention relate generally to wireless communication systems, methods, devices and computer program products and in particular to the use of the Internet Protocol (IP) over a wireless link between two system elements. Background technique

[0002] In conventional UTRAN / GERAN system implementations, the concept of radio bearers is required for establishing a connection between the radio network controller RNC and the user equipment UE. However, the radio bearer configuration procedure requires considerable signaling to negotiate transmission quality and bearer parameters. In practice, the bearer structure is hierarchical between several network entities, since UMTS bearers, radio access bearers and transport bearers (i.e. Iu bearers) are required in addition to the radio bearers used to carry flows over the radio access network RAN. ).

[0003] This type of bearer structure adds latency to stream ...
