The invention proposes a communication method and network having at least two network entities adapted to receive and/or transmit call-related information when handling a call connection, wherein at least one of the network entities is adapted to send load-related information regarding the load or condition of itself or of another network entity to a further network entity. The further network entity preferably contains a memory means for storing said load-related information. A load-information request message may be sent to another network entity as a separate message, or as part of another message. The response message returned from the addressed network entity may be returned as a separate message, or as part of another message. The network preferably is a packet-switched network, preferably a GPRS or UMTS network. |

DETAILED DESCRIPTION The present invention provides a communication network having at least two network entities adapted to receive and/or transmit call-related information when handling a call connection, at least one of the network entities preferably being adapted to communicate with another network entity arranged in another network when handling a call involving at least two networks, wherein at least one of the network entities is adapted to send load-related information regarding the load or condition of itself or of another network entity to a further network entity.
The further network entity will therefore be informed on the state of another network entity and can take account thereof when e.
g.
establishing a next call or handling an actual connection.
The invention furthermore provides a method to be performed in a communication network having at least two network entities adapted to receive and/or transmit call-related information when handling a call connection, at least one of the network entities being adapted to communicate with another network entity arranged in the same or another network when handling a call involving one or more networks, wherein at least one of the network entities will send load-related information regarding the load or condition of itself or of another network entity to a further network entity.
Preferably, the further network entity contains a memory means for storing said load-related information so that this information has to be transmitted only once or at least with larger time intervals inbetween, reducing the network and processing load.
In a preferred embodiment, the load-related information is stored in the memory together with a time-to-live value.
Older information will therefore automatically be considered as expired.
Preferably, a first one of the network entities, e.
g.
a user equipment, is adapted to send a connection-related message to a second network entity requiring or necessitating the establishment or modification of a connection to a third network entity, the second network entity being adapted to return a message to the first network entity which specifies another network entity or connection possibility different from the third network entity when the third network entity should be in a state which probably or certainly provides insufficient operation, such as high-load or overload or break-down condition
