Embodiment Construction

[0021] figure 1 A schematic diagram of a portion of a system 100 in which the invention may be applied is shown. figure 1 The system 100 is a cellular radio access network with multiple cells, figure 1 Two cells 111, 121 of the plurality of cells are shown in . In each cell there can be multiple mobile stations MS, as an example of this, figure 1 One MS 112, 122 in each of cells 111, 121 is shown.

[0022] In addition, the system 100 includes a plurality of base stations BS, and each cell 111, 121 corresponds to a base station BS, wherein the corresponding base stations of these cells are in figure 1 Shown as 113,123 in. The functionality of the BS varies between different standards, but in most systems traffic to and from MSs in a cell is routed via the BS for that cell.

[0023] Traffic from BS to MS is called downlink LD traffic, while traffic in the other direction, from MS to BS is called uplink UL traffic.

[0024] As is well known to those skilled in the art, an M...

Abstract

A method for a cellular system with a plurality of cells with mobile terminals, MSs, and a plurality of Base Stations, BSs. An MS can be handed over from a first BS to a second BS. The method comprises letting the second BS inform the first BS that an update has taken place in the system information of the second BS, and also comprises letting the first BS acquire the updated system information of the second BS, and letting the first BS transmit at least part of the updated system information of the second BS to MSs in the cell of the first BS.

Description

technical field [0001] The invention discloses a method for improved neighbor information update in a cellular system. Background technique [0002] A cellular radio access network (eg such as GSM, WCDMA and mobile WiMAX networks) comprises a number of base stations BS, where each BS covers a certain geographical area (a so-called cell). In each cell there can be a number of mobile terminals or mobile stations MS, traffic to and from the MSs in the cell is routed via the BS of that cell. [0003] An MS in the network exemplified above may move between cells, and when the MS moves between those cells there will be a so-called "handover" consisting of the MS going from the BS of one cell to the BS of another cell. [0004] An MS in a so-called active state may have multiple ongoing services such as voice calls, video streaming or best effort file downloads or uploads, for example. When there is a handover of an MS between BSs, the end user, that is, the user of the MS, expec...
