A method, apparatus and system for initiating a service change in a wireless system, the wireless system including an originating side and a terminating side. The invention includes initiating a modification request in a wireless system, wherein the modification request is a service change from a first mode to a second mode. The invention further includes modifying a terminal from a first mode to a second mode if the modification request is accepted by the terminal, and completing a radio bearer assignment after the modification request is accepted.

Network-initiated service change from speech to multimedia

Disclosed is a method of executing a handover in a system including a core network comprising two mobile services switching center. Both mobile services switching center can be accessed to by a cellular access as well as by a non-cellular access. The system further includes a terminal which can access to both mobile services switching center over the cellular access as well as over the non-cellular access. The method comprises the steps of handing over a call of the terminal to non-cellular access involving also a handover from a first one of said two mobile services switching center to a second one of said two mobile services switching center, and indicating in a message that the call of the terminal was handed over to non-cellular access, wherein said message is sent from the second mobile services switching center to the first mobile services switching center.

Method for inter-system inter-MSC handover to UMA

Disclosed herein is a method and apparatus for measuring usage of system resources in a communication network. The apparatus includes devices for measuring radio resources, data service units and transmission characteristics in the system. The devices for measuring are adapted for performing a respective collective measurement. The method includes collectively measuring transmission parameters including radio resources, data service units and transmission characteristics. The method provides for dimensioning system resources according to transmission demand in the network.

Device and method for measuring the usage of system resources in a communication network

In the present invention, a measuring device is proposed for measuring system resources which are used by a communication connection in a telecommunication network, said device comprising: means for receiving a request of allocation of system resources to establish said connection, said request indicating a preferred level of said resources, examining means ( ) for examining parameters (BCIE ) indicating said requested resources, allocating means ( ) for allocating, on the basis of the examination by said examining means ( ), available resources indicated by parameters (BCIE ) of the communication network to the communication connection, and comparing means ( ) for comparing the level of the requested resources (BCIE ) and the level of the resources allocated by the communication network (BCIE ). Furthermore, a corresponding measuring method is proposed. Using the present invention allows a operator to obtain improved knowledge of system resources.
