Problems solved by technology

[0017] A particular disadvantage of the current state of the art is that, neither according to the GSM standard nor according to the UMTS standard, the mobile wireless terminal does not have sufficient information about neighboring cells in the current cell to suppress radio technical measurements and identification of potential target cells
[0024] This document also suffers from the disadvantage that, in order to avoid unnecessary transmission of information, information on potential wireless network access avoiding further requests and transfers of wireless connections is not stored

Embodiment Construction

[0036] Supports so-called dual-mode mobile radio equipment (dual-mode UE)-that is, equipment that supports both GSM and UMTS-by transmitting proximity information about the UMTS network in the GSM network in the area where the UMTS network is above the GSM network Switch. It should be noted that as long as the UMTS network quality is good enough, through this typical parameterization for the current combined GSM / UMTS network, all dual-mode UEs comply with cell reselection from GSM to UMTS (ie, UE-based cell handover).

[0037] The exemplary domestic roaming agreement between operators A and B, for example, also stipulates that the customers of operator B are allowed to use the entire GSM network of operator A, but they do not have the right to access the UMTS part of operator A's network (even if located in the operator The customer of operator B in A's network has dual-mode UEs that support access to UMTS in principle. Therefore, the requirements of the exemplary domestic roami...

Abstract

The invention relates to a method and to an arrangement for optimising the operational times and cell change performance of mobile terminals in a mobile communication network having adjacent radio cells. The mobile terminal temporarily stores network specific characteristics for adjacent shaft cells which are not suitable for cell exchange when the mobile communication network is in operation andit uses said characteristics as decision criterion for cell exchange, and said information is used, in particular, to exclude said adjacent cells from additional radio-technical measurements and identification procedures. By implementing the terminal behaviour according to the inventive method, it is possible to significantly increase the operational times and the cell exchange performance of a mobile terminal in specific situations and to improve the service to a mobile radio user.; The inventive device can also be used for mobile terminals according to GSM- or UMTS-Standard, and also for other radio network technology (for example, wireless LAN (W-LAN), cdma2000, WiMAX, WiBro, enhanced UTRAN, etc.).

Description

Technical field [0001] The present invention relates to a method and device for optimizing the working time and cell switching performance of a mobile terminal, as it is in a cellular mobile communication system application, for example, according to the GSM standard or the UMTS standard. Background technique [0002] In cellular mobile radio networks according to the GSM standard and according to the UMTS standard, as defined by 3GPP [www.3gpp.org], for UMTS (URA_PCH, CELL_PCH and CELL_FACH), in the so-called idle mode or in the connected mode In a specific state, cell handover is achieved through a cell handover algorithm based on mobile wireless devices. The same applies to cell handover based on packet GPRS. For this cell handover, the radio network informs possible neighboring cells through the so-called radio channel (BCCH) of the corresponding terminal. [0003] The network operator is responsible for controlling the neighboring cells that are transmitted. Among them, mul...
