Abstract: Multicast/broadcast messaging service (MBMS) arrangement, in which a broadcast/multicast service center delivers multimedia messages to a plurality of users via a gateway GPRS support node (GGSN) and via a serving GPRS support node (SGSN) and a radio access network (RAN), in association with a given temporary mobile group identity (TMGI) and using a single radio access bearer (RAB). Responsive to a given event, the SGSN sends to the RAN a data volume report query identifying said RAB by the TMGI or another unique parameter. The RAN responds with a data volume report that indicates the amount of unsent MBMS data. If so agreed, the SGSN will pass said amount to a charging gateway for compensation in charging for the MBMS service.

Abstract: The invention relates to a method and system for performing packet switched handover in a mobile communication network. The system comprises a mobile node, a first and a second packet switching node. The method enables the parallel sending of logical link layer frames from the first and the second packet switching node. This is achieved so that the mobile node does not reject incoming frames received from two logical link layer entities having different states. The benefits of the invention are related to improved quality of service and the avoiding of gaps in received data during handover.

Abstract: There is proposed a mechanism for controlling a communication connection of a user equipment in a communication network. The communication network comprises at least a core network subsystem having at least one core network control element, and a first access network subsystem and at least a second access network subsystem. On one hand, when it is detected that at least one connection parameter of a communication connection of the user equipment can not be maintained by the first access network subsystem, a connection modification message is sent to the core network control element. The core network control element responds with an acknowledgement message the acknowledgement message comprising an instruction parameter for instructing that the communication connection of the user equipment is to be changed to the second access network subsystem being determined to having the capability to provide the connection parameter.

Abstract: A method provides control of access in a communication system. The method includes providing an access route via at least one unlicensed radio spectrum access network and via at least one licensed radio spectrum access network. The method further includes receiving an access request from a cell belonging to one of the at least one unlicensed radio spectrum access network and the at least one licensed radio spectrum access network. The method further includes determining whether the access request is received from a cell belonging to the at least one unlicensed radio spectrum access network or the at least one licensed radio spectrum access network. The method further includes controlling the access based on a result of the step of determining. Furthermore, a network element, a computer program and a communication system are configured to execute the method.

Abstract: There is disclosed a method of handing over communication of packet switched data from a mobile terminal moving between a first routing area defined in a cellular communications network and a second routing area, wherein a temporary logical link identifier has been assigned to said communication in the first routing area, the method comprising the steps of: identifying that the mobile terminal has moved from the first routing area to the second routing area; supplying a temporary handover identity; transmitting packets in a downlink direction to the mobile terminal during a handover period, each packet including the temporary handover identity; during said handover period assigning a new temporary logical link identifier to the mobile terminal and ceasing to include the temporary handover identity in subsequent packets when the new temporary logical link identifier has been assigned.

Abstract: The invention relates to a method for performing an intersystem handover of a mobile terminal accessing a communication network via a radio access network of a first type. The communication network comprises at least this radio access network of this first type and a radio access network of a second type. In order to enable an access to the communication network with a radio access technology required or desired by the mobile terminal, the intersystem handover is initiated by a transmission of the mobile terminal to the communication network, which transmission comprises information indicating that an intersystem handover from the radio access network of the first type to the radio access network of said second type should be performed. The invention equally relates to a corresponding mobile terminal, to a corresponding communication network, to a corresponding communication system, to a network element of a communication network and to a web switch of a communication system.
