Abstract
A solution for indicating cell characteristics that apply specifically for a mobile o terminal (3) accessing a radio cell (4) of a network node (1) in a telecommunications system (10) is described herein. The solution is provided in methods and devices for providing and handling a node identifier string with mobile terminal cell specific properties to the mobile terminal. The node identifier string may be provided in a radio resource control communication message.

A method in a radio network access node in a radio access network, for indicating characteristics of a cell of said access node to a mobile terminal accessing said cell through said access node comprising:
- sending a node identifier to said terminal, the node identifier comprising a pointer for a node identifier string indicative of cell specific properties specifically applicable with said terminal within said cell;
- and
- if the sent node identifier matches a node identifier pre stored in said terminal resulting in said terminal establishing a Radio Resource Control (RRC) connection to said access node, then providing the node identifier string to said terminal from said access node over the established RRC connection.
A method implemented in a mobile terminal accessing a radio network access cell in a radio access network, for indicating characteristics of said cell on said terminal, comprising the steps of:
- receiving a node identifier provided from a network access node of said cell, said identifier comprising a pointer for a node identifier string indicative of cell specific properties specifically applicable with said terminal within said cell;
- matching said received node identifier with a pre stored node identifier;
- if the received node identifier matches the pre stored node identifier and if an associated pre stored node identifier string exists and associates to a set of terminal specific cell properties, using the pre stored node identifier string in the terminal;
- and
- if the received node identifier matches the pre stored node identifier but an associated pre stored node identifier string does not exist, then:
- obtaining the node identifier string from the network access node;
- associating the obtained node identifier string with the pre stored node identifier;
- and
- using the obtained node identifier string in the terminal.
An access node of a telecommunications network, arranged to indicate characteristics of a radio cell of said access node to a mobile terminal accessing said cell, wherein the access node is configured to:
- send a node identifier to said terminal, the node identifier comprising a pointer for a node identifier string indicative of cell specific properties specifically applicable with said terminal within said cell;
- and
- if the sent node identifier matches a node identifier pre stored in said terminal resulting in said terminal establishing a Radio Resource Control (RRC) connection to said access node, then provide the node identifier string to said terminal from said access node over the established RRC connection.
A mobile terminal accessing a radio cell of an network access node in a telecommunications network, arranged to indicate characteristics of said cell, wherein said terminal is arranged to:
- receive a node identifier provided from the network access node of said cell, said node identifier comprising a pointer for a node identifier string indicative of cell specific properties specifically applicable with said terminal within said cell;
- match the received node identifier with a node identifier pre stored in the memory of the terminal;
- if the received node identifier matches the pre stored node identifier and an associated pre stored node identifier string exists and associates to a set of terminal specific cell properties, the terminal is arranged to use the pre stored node identifier string in the terminal;
- and
- if the received node identifier matches the pre stored node identifier but an associated pre stored node identifier string does not exist, the terminal is arranged to:
- obtain the node identifier string from a network access node;
- associate the obtained node identifier string with the pre stored node identifier;
- and
- use the obtained node identifier string in the terminal.
