Problems solved by technology

[0011] The above method is not optimal in case of E-DCH technology, because the medium access control (Mac-e) will be located in the Node B, and the available E-DCH resources have to be shared with other users (in a shared channel way)

Embodiment Construction

[0032] The SPI can be associated with the RLC buffer in the UE in different ways, eg by means of Radio Resource Control (RRC) signaling from the Radio Network Controller (RNC).

[0033] Figure 1 presents the basic idea of ​​the invention: each of a number of UEs 1, 2 comprises several RLC buffers associated to radio bearers with different indication, where eg a higher SPI indicates a higher priority. UE 1 is shown with four buffers 3, 4, 5, 6 for storing packets with different SPIs 3, 6, 6, 8 respectively, while UE 2 is shown with four buffers 7, 8, 9, 10, used to store packets with different SPI 0, 3, 5, 8 respectively. Of course, it should be appreciated that at any given time, the SPI associated with a given buffer may change according to the MAC-d flow or logical channel. Only buffer 3 in UE 1 has any data packets at the time it is ready for transmission. Similarly, only buffer 10 in UE 2 has any data packets at the time it is ready for transmission. A capacity request...

Abstract

A system has user equipment (1; 2) each having buffers (3, 4, 5, 6; 7, 8, 9, 10) for storing packets classified according to priority and ready for transmission over a radio interface to a network element (12). In such a system, user equipment sends capacity request signals (11; 13) indicative of the various priorities of the buffered packets on the radio interface to the network element. Rather than seeking a capacity allocation decision from a higher level in the core network, the network element itself makes the capacity allocation decision and provides a capacity allocation signal (14) to the user equipment. Packets that have thus been allocated capacity by the network element are then sent from the user equipment to the network element. Having the network element make the capacity allocation decisions itself is a more efficient system since the network element is in direct communication with the user equipment over the radio interface and the decision is made in an unmediated way.

Description

Background technique [0001] In the known 3rd Generation Partnership Project (3GPP) for mobile communications, there is a developing project called "Enhanced Uplink for UTRA FDD" involving the Group Radio Access Network. Feasibility Study for Enhanced Uplink for UTRA FDD (Release 6) (Feasibility Study for Enhanced Uplink for UTRA FDD, (Release 6))". The acronym UTRA stands for "UMTS Terrestrial Radio Access" and FDD stands for "Frequency Division Duplex". "UMTS" means Universal Mobile Telecommunications System (Universal Mobile Telecommunications System) and "Uplink (Uplink)" refers to the direction from the mobile user equipment (UE) to the wired core network through the wireless interface. Release 6 refers to all IP (Internet Protocol) 3GPP solutions (it should be recognized that "all IP" can mean different things, and that Release 6 can be implemented without "all" IP). This specification is in the form of a Technical Report (TR) with the given number 3GPP TR 25.896 V6.0.0...
