Abstract

The invention relates to communication of information in fixed-length messages in mobile communication systems, particularly in association with positioning methods. In a method according to the invention information is transferred in a fixed-length message such that the payload portion of the message includes content information to define the contents of the payload portion of the message, and in accordance with the content information the payload portion of the message includes information elements defined by the content information.

Claims

1. A method in a mobile communication system for transferring information in a fixed-length message from a base station to at least one mobile station, wherein

content information is transferred in the payload portion of the message for defining the contents of the payload portion of the message, and

information elements defined by said content information are transferred in the payload portion of the message according to said content information.

2. A method according to claim 1 wherein said information elements comprise at least information elements containing position data.

3. A method according to claim 2 wherein said information elements define the location of at least one neighbor base station relative to the base station.

4. A method according to claim 1 wherein said content information defines a value range for data to be transferred corresponding to the binary value range of at least one information element.

5. A method according to claim 1 wherein said content information defines the magnitude of the step of the value of data to be transferred corresponding to the smallest binary value step of at least one information element.

6. A method according to claim 1 wherein information elements of predetermined length are transferred in the payload portion of the message in addition to the information elements defined in said content information.

7. A method according to claim 1 wherein said fixed-length message is an SMS-CB message.
