However, the length of this delay can easily reach hundreds of milliseconds or even as long as several seconds, which is definitely too long for real-time services. This long delay is at least a disturbance, and if the delay is interpreted as A severe outage of the system can even cause the call and other connections to
This long delay also frustrates users of non-real-time services, even when it does not actually affect the intelligibility of the transmitted information, for example, because the delay unnecessarily slows down the download of web pages

Embodiment Construction
[0031] An important general reason behind the initiation of a cell change is that the received signal strength appears to be significantly higher between the mobile station and the new base station than between the mobile station and the old base station. The new cell may also belong to a local area, or some other group of preferred cells, in which case it may be advantageous to change cells, even if the signal strength criteria are not met. The network may even order some mobile stations to change cells for some administrative reasons, such as traffic congestion at night. The actual initiation of the cell change can come from the mobile station or from the network. The invention is equally applicable regardless of where the initiation of the cell change comes from and what is the reason behind it. Naturally, restrictions imposed by network specifications have to be respected: for example, in some cases the network may not allow the mobile station to initiate a cell change by...

A method is presented for implementing a cell change for a mobile station (MS) in a packet-switched cellular radio system comprising a first base station (BTS old), a second base station (BTS new) and a controlling unit (PCU, PCU old) controlling the operation of at least the first base station (BTS old). The method comprises the steps ofestablishing at the controlling unit (PCU, PCU old) the knowledge about the mobile station's (MS) need for performing a cell change from the cell of the first base station (BTS old) to the cell of the second base station BTS new) while the mobile station (MS) is still communicating with the first base station (BTS old),transmitting from the controlling unit (PCU, PCU old) towards the mobile station through the first base station (BTS old) a first message (207, 309, 410) in order to fix an oncoming first moment of lime (209) as the moment of performing cell change andfrom said first moment of time onwards (209) providing access for the mobile station to the cell of the second base station.
Description
technical field [0001] The present invention relates generally to the technical field of packet-switched cellular radio systems. More precisely, the invention relates to a cell change procedure, ie for rerouting an efficient packet-switched communication connection between a mobile station and a fixed packet-switched network via a new base station. An important application structure for the present invention is the GPRS (General Packet Radio Service) system, which is described in detail on the priority date of this patent application. Other at least equally important application frameworks are UMTS (Universal Mobile Telecommunications System), in which so-called connectionless data services are packet-switched, and EDGE (Enhanced Data Rates developed for GSM), in which connectionless data services will also be implemented. Background technique [0002] Services provided over telecommunication connections can be broadly classified as real-time and non-real-time services. Th...
