Definitions
- the invention relates to a subscriber-controlled method for selecting the QoS level during a connection between a first media gateway, which is assigned to a first subscriber, and a second media gateway, which is assigned to a second subscriber, in a packet network Change of a CODEC or in a network by changing the transmission technology.
- An end user for example a PC user or a telephone customer, should be able to determine for himself whether a connection is switched via the Internet or networks with different QoS or via a TDM network. So far, however, there have only been methods that, on the one hand, allow the QoS level to be controlled implicitly by the network operator or, on the other hand, explicitly by the subscriber when establishing the connection. With pure IP connections, it is possible to change the QoS level by selecting different CODECs even during the connection.
- a CODEC is understood as a coder-dicoder, a unit for information transmission. However, this is not possible for connections that are only partially switched via the IP network.
- QoS means quality of service.
- the object of the invention is to provide a method with which the selection of the QoS level can also be changed during a connection by a subscriber or a network operator without the connection being broken off.
- the object is achieved by a method having the features of claim 1.
- the method according to the invention makes it possible to change from a low QoS level to a high change here, as well as in the opposite direction. With this procedure, both a subscriber and his network operator can determine the quality of the connection themselves during the call. This increases the acceptance of Internet connections because in the event of bottlenecks and failures on the Internet, the higher quality of TDM connections can also be made available to the IP customer.
- the method can also be used to automatically switch customers of the IP network to the TDM network based on measurements of the QoS level. This is also of great benefit to the carriers, since their customers generally want to receive a high degree of QoS. If the connections between two subscribers are too severely disrupted, they will otherwise terminate their connections, which on the one hand leads to a loss of fees for the carrier and on the other hand to a loss of customer satisfaction. This problem no longer occurs with the invention.
- the object is achieved by a method with the features of claim 2.
- the selection of the QoS level is not achieved by changing a CODEC, but by changing the transmission technology, for example from an IP network to a TDM network or vice versa.
- the subscriber or his network operator can change the QoS level during a connection, for example if the QoS is too bad, without interrupting it.
- an IP connection is rerouted to a TDM connection or vice versa, while the connection continues. As already explained for claim 1, this can be done by both a subscriber and a network operator, in particular automatically in the case of a poor connection. This makes it possible to set the QoS level to the desired quality during a connection.
- the first media gateway has a first and a second TDM Endpoint and the second media gateway connects a third and a fourth TDM endpoints and the original IP connection is triggered. This enables the connection to be reconfigured in a very simple and quick manner.
- the TDM connection between the first media gateway controller and the second media gateway controller is established in accordance with the standard, in particular via an E.164 call number. This means that no special requirements are placed on the TDM exchanges. This leads to extremely little effort when establishing a connection, since special handling is only required in the media gateway controllers.
- the first subscriber 2 is connected to a first media gateway 1 via a first TDM end point 8 of a first TDM network 13 via TDM trunks.
- 12 IP packets are forwarded between the first media gateway 1 and a second media gateway 3 via an IP connection.
- the connection goes via TDM trunks to a second TDM endpoint 10 in a second TDM network 14. From there, the information reaches the second subscriber 4.
- VoIP Voice over IP
- the first subscriber 2 determines that the QoS level of the IP connection 12 is too low and interference occurs, he signals via the first TDM end point 8 to a first media gateway controller 5 which is assigned to the first media gateway 1, via a suitable protocol, for example N-ISUP, that he wants more QoS.
- the first media gateway controller 5 signals these service requests via a suitable interface, for example an IP network network interface (IP-NNI), to a second media gateway controller 6 assigned to the second media gateway 3.
- IP-NNI IP network network interface
- the second media gateway Controller 6 determines a call number via which a TDM connection 7 to the second media gateway 3 can be established.
- the first media gateway controller 5 is also connected to a second TDM end point 9 in the third TDM network 15 via a suitable protocol, for example N-ISUP.
- the two TDM end points 9, 11 in the third TDM network 15 also communicate via a suitable protocol, for example N-ISUP.
- the second media gateway controller 6 signals the number found to the first media gateway controller 5.
- the first media gateway controller 5 After the first media gateway controller 5 has determined the call number of the second TDM end point 9 in the third TDM network 15, it sets up the TDM connection 7.
- the IP connection 12 is then reconfigured to the newly set up TDM connection 7.
- the first media gateway 1 connects the first TDM endpoint 8 in the first TDM network 13 to the second TDM endpoint 9 in the third TDM network 15.
- the second media gateway 3 connects the third TDM endpoint 10 in the second TDM network.
- the connection within the third TDM network 15 is done like the other connections just described via TDM trunks. Subsequently, the previously existing IP connection 12 is triggered.
- the new sales The connection between the first subscriber 2 and the second subscriber 4 now runs via the first TDM end point 8 in the first TDM network 13, the first media gateway 1 in the IP network 16, and the second TDM end point 9 in the third TDM network 15 , the fourth TDM end point 11 in the third TDM network 15, the second media gateway 3 in the IP network 16 and the third TDM end point 10 in the second TDM network 14 to the second subscriber 4.
