Claims
- 1. A method for modification of a connection between a transmitting subscriber and a receiving subscriber in a communications system, which is based on data compression, within a switching center, comprising:
formatting a data frame based on a framing protocol, which arrives in the switching center and is replaced independently of a length of the data frame by a new data frame formatted based on the framing protocol, such that additional information is configured to be fed into the connection without any loss of quality or time or removing the data frame which arrives at the switching center is removed; and ______if the data frame which arrives at the switching center is missing, generating or inserting one or more new data frames, which are formatted based on the framing protocol, into the connection.
- 2. The method as claimed in claim 1, wherein a UMTS system is chosen as a communications system based on data compression.
- 3. The method as claimed in claim 2, wherein, depending on a respective length, the data frame arriving at the switching center arrives in a segmented form, and the new data frame is segmented into one or more AAL2 packets, which are each provided with a packet header field.
- 4. The method as claimed in claim 3, wherein the packet header fields of the AAL2 packets are each used to indicate the data frame with which a respective AAL2 packet should be associated.
- 5. The method as claimed in claim 3, wherein the packet header fields of the AAL2 packets are each used to indicate whether subsequent AAL2 packets which are associated with a data frame will follow.
- 6. The method as claimed in claim 3, wherein an end of the data frame of the connection to be modified is delayed before replacement begins, for which the data frames are not recreated from the AAL2 packets, and an end of a data frame is defined by evaluation of a respective packet header field.
- 7. The method as claimed in claim 3, wherein the AAL2 packets are combined into ATM cells, which are specified for a receiving subscriber.
- 8. An apparatus for modification of a connection between a transmitting subscriber and a receiving subscriber in a communications system, based on data compression, within a switching device, comprising: a data frame which arrives in the switching center and is formatted based on a framing protocol and is configured to be replaced by the apparatus by a new data frame, irrespective of a length of the data frame, such that additional information is configured to be fed into the connection without any loss of quality or time, or the data frame which arrives at the switching center is removed, or if the data frame which arrives at the switching center is missing, one or more new data frames, which are formatted based on the framing protocol are generated and inserted into the connection.
