Abstract

A presence server unit, which manages presence information relating to the availability of a communication unit and informs a plurality of checking units about changes to the presence information on the basis of a notification ranking which is specified by priority information.

Claims

1. A presence server unit comprising:

a manager which is designed to manage presence information relating to the availability of a communication unit;

a receiving device which is designed to receive a message from each checking unit of a plurality of checking units, which message specifies that, when the presence information is changed, change information relating to the change to the presence information should be transmitted to the respective checking units;

a memory in which priority information is stored, which priority information is information relating to a notification ranking on the basis of which the change information should be transmitted to the plurality of checking units and which is contained at least partially in the message received from one checking unit of the plurality of checking units, with the priority information which is contained in the message which is received from the checking unit of the plurality of checking units specifying that the change information should be transmitted to this checking unit before the change information is transmitted to the other checking units in the plurality of checking units; and

an information device which is designed to transmit the change information, when the presence information is changed, in accordance with the notification ranking to the plurality of checking units.

2. The presence server unit as claimed in claim 1, wherein the priority information is at least partially defined by a user of the communication unit.

3. The presence server unit as claimed in claim 1, wherein the presence server unit has a determination device, which is designed to determine a notification ranking using the priority information.

4. The presence server unit as claimed in claim 1, wherein at least one checking unit from the plurality of checking units is a communication terminal.

5. The presence server unit as claimed in claim 1, wherein at least one checking unit from the plurality of checking units is a mobile radio subscriber appliance.

6. The presence server unit as claimed in claim 1, wherein the presence information specifies whether a communication link can be set up to the communication unit.

7. The presence server unit as claimed in claim 1, wherein the communication unit is a mobile radio subscriber appliance.

8. The presence server unit as claimed in claim 1, wherein the notification ranking specifies that a first portion of the plurality of checking units should be informed first of about the change to the presence information, and the remaining portion of the plurality of checking units should be informed about the change to the presence information when a further change is made to the presence information and/or after a defined time period following a change to the presence information if no communication link has been set up to the communication unit in that time period.

9. A method for controlling a presence server unit, which manages presence information relating to the availability of a communication unit, the method comprising the steps of:

the presence server unit receiving a message from each checking unit in a plurality of checking units, which message specifies that when the presence information is changed, change information relating to the change to the presence information should be transmitted to the respective checking units;

using priority information, which is information about a notification ranking on the basis of which the change information should be transmitted to the plurality of checking units and which is contained at least partially in the message received from one checking unit of the plurality of checking units, with the priority information which is contained in the message which is received from the checking unit of the plurality of checking units specifying that the change information should be transmitted to this checking unit before the change information is transmitted to the other checking units of the plurality of checking units; and

when the presence information is changed, transmitting the change information on the basis of the notification ranking from the presence server unit to the plurality of checking units.

10. A communication arrangement comprising:

a presence server unit which manages presence information relating to the availability of a communication unit; and

a plurality of checking units, with each checking unit from the plurality of checking units being designed to produce a message and to transmit this message to the presence server unit, which message specifies that when the presence information is changed, change information relating to the change to the presence information should be transmitted to the respective checking units,

wherein the presence server unit has a memory in which priority information is stored, which priority information is information relating to a notification ranking on the basis of which the change information should be transmitted to the plurality of checking units and which are contained at least partially in the message received from one checking unit of the plurality of checking units, with the priority information which is contained in the message which is received from the checking unit from the plurality of checking units specifying that the change information should be transmitted to this checking unit before the change information is transmitted to the other checking units in the plurality of checking units, and

wherein the presence server unit has an information device which is designed to transmit the change information, when the presence information is changed, in accordance with the notification ranking to the plurality of checking units.

11. A method for operating a communication arrangement having a presence server unit which manages presence information relating to the availability of a communication unit, the method comprising the steps of:

each checking unit of a plurality of checking units producing a message and transmiting this message to the presence server unit, which message specifies that when the presence information is changed, change information relating to the change to the presence information should be transmitted to the respective checking unit;

a memory in the presence server unit storing priority information, which is information relating to the notification ranking on the basis of which the change information should be transmitted to the plurality of checking units and which is contained at least partially in the message received from one checking unit of the plurality of checking units, with the priority information which is contained in the message which is received from the checking unit of the plurality of checking units specifying that the change information should be transmitted to this checking unit before the change information is transmitted to the other checking units in the plurality of checking units; and

an information device in the presence server unit transmiting the change information, when the presence information is changed, in accordance with the notification ranking to the plurality of checking units.

12. A presence server unit comprising:

a managing means for managing presence information relating to the availability of a communication unit;

a receiving means for receiving a message from each checking unit of a plurality of checking units, which message specifies that, when the presence information is changed, change information relating to the change to the presence information should be transmitted to the respective checking units;

a memory means for storing priority information, which is information relating to a notification ranking on the basis of which the change information should be transmitted to the plurality of checking units and which is contained at least partially in the message received from one checking unit of the plurality of checking units, with the priority information which is contained in the message which is received from the checking unit of the plurality of checking units specifying that the change information should be transmitted to this checking unit before the change information is transmitted to the other checking units in the plurality of checking units; and

an information means for transmiting the change information, when the presence information is changed, in accordance with the notification ranking to the plurality of checking units.
