Abstract
The present invention relates to a method for transportation of user information in a core network (CN). The core network is located between a source access network (SAN) and a destination access network (DANB). The method comprises the following steps: collecting in a source center (MSCa) in the source network (SAN) of voice packets from source units (1a, 2a, 3a, 4a, 5a) in the source network. The voice packets have the destination network (DANB) specified as receiving network; arranging of the collected voice packets into a payload part (IPPL) of an IP-packet (IP) in the core network (CN); transferring of the IP-packet in the core network (CN) from the source center (MSCa) to a destination center (MSCb) in the destination network (DANB).
Claims8
A method of transporting voice packets in a core network from a source access network to first and second destination access networks, said method comprising the steps of:
- collecting in a source center in the source network, a plurality of voice packets from multiple source units in the source network, wherein a first portion of the voice packets are addressed to a destination in the first destination network, and a second portion of the voice packets are addressed to a destination in the second destination network;
- loading the collected voice packets into a payload part of an IP-packet in the core network without changing a protocol format of the voice packets;
- transferring the IP-packet in the core network from the source center to a destination center in the first destination network;
- unloading the voice packets from the IP-packet by the destination center;
- delivering by the destination center, the first portion of voice packets utilizing the protocol format of the voice packets;
- loading the second portion of voice packets into a second IP-packet;
- and
- forwarding the second IP-packet in the core network from the first destination network to the second destination network.
A system for transporting voice packets in a core network from a source access network to first and second destination access networks, said system comprising:
- means for collecting in a source center in the source network, a plurality of voice packets from multiple source units in the source network, wherein a first portion of the voice packets are addressed to at least one destination in the first destination network, and a second portion of the voice packets are addressed to at least one destination in the second destination network;
- means for loading the collected voice packets into a payload part of an IP-packet in the core network without changing a protocol format of the voice packets;
- means for transferring the IP-packet in the core network from the source center to a destination center in the first destination network;
- means in the destination center for unloading the voice packets from the IP-packet;
- means in the destination center for delivering the first portion of voice packets to the at least one destination in the first destination network utilizing the protocol format of the voice packets;
- means for loading the second portion of voice packets into a second IP-packet;
- and
- means for forwarding the second IP-packet in the core network from the first destination network to the second destination network.
A network node in a first destination network for transporting voice packets, said network node comprising:
- means for receiving from a core network, an IP packet in which a plurality of voice packets from multiple source units are loaded, wherein a first portion of the voice packets are addressed to at least one destination in the first destination network, and a second portion of the voice packets are addressed to at least one destination in a second destination network;
- means for unloading the voice packets from the IP-packet;
- means for delivering the first portion of voice packets to the at least one destination in the first destination network utilizing a protocol format of the voice packets;
- means for loading the second portion of voice packets into a second IP-packet;
- and
- means for forwarding the second IP-packet in the core network to the second destination network.
