Abstract
A method and an apparatus implementing the method for optimizing data transmission resources, particularly resources on the air interface, between terminals and a network element. To diminish capacity differences of different legs or connection parts in the connection, the network adapts (2-5, 2-10A, 2-13) the traffic channel resources between the terminal and the network to be suitable for the outward connection of the network element, e.g. the connection to another mobile station or to a fixed network, by observing and comparing the data transmission capacities of the connection parts or by receiving from the outward connection part the information (2-4, 2-9A, 2-9B, 2-12, 2-14) on its data transmission capacity.
Claims24
A method for optimizing the use of data transmission resources, the method comprising:
- forming an end-to-end connection between a terminal in a telecommunication system and another party of the end-to-end connection, the end-to-end connection including a first connection part between the terminal and a network element in the telecommunications system and a second connection part between the network element and the other party,
- monitoring the end-to-end connection to detect an event indicating a difference between a capacity of the first connection part and a capacity of the second connection part,
- defining an extent of a detected event,
- checking whether an extent of the detected event fulfills a predetermined condition, and
- if the condition is fulfilled, changing the capacity allocated to the first connection part from data transmission resources in such a manner that a difference between the capacities of first and second connection parts decreases.
A method for optimizing the use of resources on an air interface between a mobile station in a mobile communication system and a communication network in a data call between the mobile station and another part of the data call, the method comprising:
- forming an end-to-end connection including a first leg between the mobile station and a network element in the mobile communication system and a second leg between the network element of the mobile communication system and the other party,
- maintaining information indicating a capacity of the first leg on the air interface,
- receiving information indicating a capacity of the second leg,
- comparing the capacities of the first and second legs with each other,
- if the capacities differ from each other, changing the capacity of the first leg on the air interface to correspond to the capacity of the second leg.
A mobile communication system comprising:
- a plurality of mobile stations including a first mobile station and a second mobile station,
- an air interface between the first and second mobile stations and the mobile communication system, and
- a first network element configured to form a first leg of the connection between the first mobile station and the first network element, the first network element being configured to allocate capacity to the first leg from the air interface, and
- a second network element configured to form the second leg between the second mobile station and the second network element, the second network element being configured to allocate capacity to the second leg from the air interface,
- wherein the first network element is configured to maintain information on the capacity allocated to the first leg from the air interface, receive information on the capacity of the second leg, compare the capacities of the first and second legs with each other and change the capacity of the first leg to correspond to the capacity of the second leg based on a difference between the capacities of the first and second legs, and the second network element is configured to transmit information associated with the capacity of the second leg to the first network element.
A network element for a telecommunication network, the network element comprising:
- an interworking function
- and being configured to (i) monitor a connection between a terminal in connection with the telecommunication network and a second party,
- (ii) detect an event indicating a difference between a capacity of a first connection part between the terminal and the interworking unit and a capacity of a second connection part between the second party and the interworking unit, (iii) define an extent of the event and (iv) change capacity allocated to the connection from data transmission resources between the telecommunication network and the terminals when the extent of the event fulfills a predetermined condition.
