Problems solved by technology

However, some situations such as RLC (radio link control) data block retransmissions and sending grant assignments to mobile stations in the uplink direction will add delay and may cause all uplink radio transmitters to some mobile stations to grant waste of

Embodiment Construction

[0022] Figure 1 is a simplified block diagram showing at the network element level the most important parts of the wireless system and the interfaces between them. The main parts of the wireless system are Core Network (CN) 100 , Radio Access Network 130 and User Equipment (UE) 170 . Radio access network 130 may be implemented by Wideband Code Division Multiple Access (WCDMA) technology. The structure and function of the network elements are not described in detail because they are generally known.

[0023] Mobile Services Switching Center (MSC) 102 is a mobile network element that may be used to serve radio access network and base station system 160 connections. The tasks of the mobile services switching center 102 include: switching, paging, user equipment location registration, handover management, collection of subscriber billing information, encryption parameter management, frequency allocation management and echo cancellation. The number of mobile services switching ce...

Abstract

There is provided a radio system comprising a remote network element, a packet control unit and a mobile station, the radio system being configured to communicate control blocks and data blocks between the mobile station, the packet control unit and the remote network element, the control blocks controlling data transmission in the radio system. The packet control unit is configured to determine which given packet control unit functionalities related to the transmission of given control or data blocks are to be distributed from the packet control unit to a remote net-work element, and to provide to the remote network element control information on which packet control unit functionalities are distributed to the remote network element; and the remote network element is configured to perform the given packet control unit functionalities for given control blocks or data blocks on the basis of the control information received from the packet control unit.

Description

field of invention [0001] The invention relates to a method for controlling data transmission in a wireless system, and relates to a wireless system, a grouping control unit, a remote network element, a base transceiver station and a base station controller. Background technique [0002] In known wireless systems, a packet control unit can control the communication between the mobile station and the wireless system via a wireless interface. The packet control unit uses the RLC (Radio Link Control) / MAC (Media Access Control) protocol in communication between the mobile station and the network. When the packet control unit is located separately from the base station, e.g. RLC / MAC retransmissions and uplink transmission allowance assignments do not work as optimally as possible because the interface used between the base station and the packet control unit introduces delays in operation . [0003] For example, RLC round trip delay is an important measure of (E)GPRS (Enhanced ...
