Embodiment Construction

[0054] Referring to Figure 1, a typical structure of a cellular radio network according to the present invention is described. Fig. 1 only includes the parts related to the description of the present invention. It is obvious to those skilled in the art that a common cellular wireless network also includes other functions and structures, which need not be described in detail here. These examples show cellular radio networks using TDMA (Time Division Multiple Access), but the invention is not limited thereto. The invention is also applicable to GSM-based cellular radio networks, in other words to systems based at least in part on the GSM specification. An example is UMTS (Universal Mobile Telephone System).

[0055] A cellular radio network generally comprises a fixed network infrastructure, ie a network part 128, and mobile stations 150, which may be in the form of fixed installed, vehicular or portable terminals. Network portion 128 includes base stations 100 . A base stati...

Abstract

The invention relates to a method for reconfiguring a cellular radio network connection (170) comprising a network part (128) having a connection (170) to a mobile station (150) through at least one radio bearer. According to the invention, a first party of the connection (170), i.e. the network part (128) or the mobile station (150), sends a second party of the connection (170), i.e. the mobile station (150) or the network part (128), a reconfiguration request message (BEARER_RECONF_REQ) concerning at least one radio bearer. The second party of the connection (170) possibly replies to this by sending the first party of the connection (170) a reply message (BEARER_COMPL / BEARER_FAIL) to the radio bearer reconfiguration request message (BEARER_RECONF_REQ). The radio bearer reconfiguration request message (BEARER_RECONF_REQ) comprises at least one radio bearer identifier (BID) and, for example, bearer quality of service (BEARER QOS) of the radio bearer in question. The possible reply message (BEARER_COMPL / BEARER_FAIL) comprises at least one radio bearer identifier (BID) and possibly also bearer quality of service (BEARER QOS) assigned to the radio bearer in question, or a cause (CAUSE) for a failed reconfiguration of the radio bearer in question.

Description

[0001] This application is a divisional application with the application number 98813368.7 and the title of the invention "Connection Reconfiguration Method in Cellular Wireless Network". technical field [0002] The invention relates to a method for reconfiguring a cellular wireless network connection. The reconfiguration relates in particular to the radio bearers providing the connection between the network part and the mobile station. Background technique [0003] In GSM systems, connection reconfiguration involves modification of the call pattern. This process is called mid-call modification. The term 'mode' refers to the operational state of the call; it may be, for example, standard voice mode, data mode, fax mode, alternate voice / data mode or alternate voice / fax mode. When a connection is reconfigured, its model can be changed eg from voice mode to data mode. If the channel used for the connection does not support the required features, the channel configuration ca...
