Embodiment Construction

[0086] The invention will now be described in more detail with reference to the embodiments described in the detailed description and shown in the accompanying drawings.

[0087] An embodiment of the invention represents a method, Node-B, for allocation and priority handling. The system and the Node-B in the system comprise means for performing the method steps described in the method. Therefore, those skilled in the art should understand the fact that the system and the Node-B execute the method steps, which means that the method embodiments described in the detailed description also include the system and the Node-B, even if they are not described in detail herein.

[0088] figure 1 and figure 2 Shows the HSUPA / HSDPA network overview. figure 1 shows a network with only one node of each kind, while figure 2Option to show the same network with more than one node of each category. A user terminal (UE) 15 communicates with a core network (CN) via at least one Node-B (NB) ...

Abstract

The present invention relates to a method and a telecommunication system for allocation and priority handling and a Node-B in the system enabling said method. The telecommunication system comprises at least one radio network controller (RNC) 12,12',12'', and at least one Node-B (NB) 11,11',11'' for enabling wireless communication with at least one user terminal (UE) 15. The RNC 12,12', 12'' establishes at least one enhanced dedicated transport channel (E-DCH) which enables uplink data traffic with a determined maximum data rate from the user terminal (UE) 15 to the Node-B (NB) 11,11', 11''. The RNC 12,12',12'' further establishes at least one high speed DL shared channel (HS-DSCH) which enables downlink data traffic with a determined maximum data rate from the Node-B (NB) 11,11',11'' to the user terminal (UE) 15. The Node-B (NB) 11,11',11'' comprises a HSDPA scheduler (HS-S) scheduling the data rate for the DL data traffic via the HS- DSCH and a EUL scheduler (EUL-S) scheduling the maximum data rate for the UL data traffic via the E-DCH. What particularly characterizes the invention is that the Node-B (NB) 11,11',11'' exchanges data rate information between the HSDPA scheduler (HS-S) and the EUL scheduler (EUL-S). Furthermore, the Node-B (NB) 11,11',11'' monitors the quotient (Q) between DL data rate and the UL data rate. Finally, when Q fulfils determined traffic conditions the HSDPA scheduler (HS-S) and/or the EUL scheduler (EUL-S) changes the allocation and/or the priority handling of the UL and/or the DL resources.

Description

technical field [0001] Embodiments relate to methods and telecommunication systems for allocation and priority handling and Node-Bs in the systems implementing said methods. Background technique [0002] There is an ever-increasing need to provision wireless technologies with the broadband capabilities of cellular networks. A good broadband system must meet certain criteria such as high data rate and capacity, low cost per bit, good quality of service and greater coverage. High Speed ​​Packet Access (HSPA) is one example of a network access technology that implements this aspect. [0003] HSPA is a set of protocols that enhance the performance of the existing Universal Mobile Telecommunications System (UMTS), a third generation (3G) cellular telephone technology. UMTS uses Wideband Code Division Multiple Access (WCDMA) as the air interface for radio-based communication between User Equipment (UE) in the form of mobile terminals and Node-Bs (NB). The air interface in the O...
