Embodiment Construction

[0021] refer to figure 1 , shows an example of a wireless system in which preferred embodiments of the present invention may be implemented. figure 1 The wireless systems in , known at least as UMTS (Universal Mobile Telecommunications System) and IMT-2000 (International Mobile Telecommunications 2000), represent third generation wireless systems. However, embodiments are not limited to the systems described here by way of example, and those skilled in the art may also apply the guidance to other wireless systems incorporating corresponding features.

[0022] figure 1 is a simplified block diagram showing the most important parts of a wireless system and the interfaces between them at the network element level. Since it is known, the structure and function of the network element will not be described in detail here.

[0023] The main parts of the wireless system are Core Network (CN) 100 , Radio Access Network 130 and User Terminals (UE) 170 . The term UTRAN is short for U...

Abstract

There is provided a radio system including a network element and at least one user terminal supporting MBMS (multimedia broadcast multicast service), the network element being configured to transmit MBMS control information elements from the network element to the user terminal for controlling an MBMS session. The network element comprises: a detection unit for detecting a requirement for more capacity for an MBMS session in the radio system; a processing unit for including an MBMS bearer description in an MBMS control information element to be transmitted to the user terminal, the MBMS bearer description including an assignment to a given MBMS bearer depending on the detected requirement for more capacity; and a transmission unit for performing an MBMS transmission between the network element and the user terminal on the assigned MBMS bearer on the basis of the MBMS bearer description included in the MBMS control information element.

Description

technical field [0001] The invention relates to a method for controlling wireless resources, a wireless system, a network element, a user terminal, a computer program product and a computer program distribution medium. Background technique [0002] MBMS (Multimedia Broadcast Multicast Service) is a point-to-multipoint capable unidirectional service for the simultaneous transmission of video, audio and other multimedia content from a wireless network to multiple recipients. In this case, MBMS bearer is more efficient than traditional point-to-point transmission. MBMS has two modes of operation: broadcast mode and multicast mode. The broadcast mode is generally considered to be free, while the multicast mode is generally considered to be charged on a subscription basis. In currently existing methods, information about MBMS content can be delivered to user terminals through point-to-point SMS (Short Message Service), CBCH (Cell Broadcast Channel), and WAP (Wireless Applicatio...
