Abstract: A system of managing collaborative session control when controller is lost or changes to passive-control mode in a data communication network comprising of a control-capable terminal device that can generate and send user preferences on successive controller selection and control policy, a master server device that can make control transfer decisions or take over control upon events, a normal terminal device that can process and response to master server queries on control capacity and its willingness to take over control. These apparatus are connected to each other inside one collaborative session, regardless of their subscriptions. A method of control management of the collaborative session without constant enrollment of controller comprises the steps of sending different types of preferences to master server device; making control transfer or handover decision; and interacting with affected terminals.

Abstract: A system of normal service resumption comprising of a UE that is currently behaving as emergency attached after receiving an limited service indication from the network, sends a behaviour change request message when the UE enters a new tracking area with a tracking area identity that is not included in the forbidden list. The network node accepts the behaviour change request when it receives a behaviour change request message from a UE that is currently behaving as emergency attached and sending the behaviour change request message from an area wherein the UE can obtain normal service. Subsequently, the said UE and network node consider the UE to be normally attached after the behaviour change request has been accepted.

Abstract: Provided is a radio communication apparatus capable of reducing power consumption of user equipment by improving efficiency in the use of radio resources even in a case when a network node and the user equipment hold a plurality of bearer contexts shared therebetween. The apparatus comprises an information determination unit (101), a QoS determination unit (102) and a control unit (104). The information determination unit (101) determines whether the type of information to be transmitted is signaling or data. When the above type is data, the QoS determination unit (102) determines, on the basis of the QoS for the information to be transmitted, whether or not the information to be transmitted requires real-time transmission. When the above type is signaling, the control unit (104) selects a first establishment method for establishing just a signaling connection, without establishing a radio bearer, between the apparatus and a communication counterpart thereof.

Abstract: Systems, apparatus and methods for resource limitation in wireless networks are disclosed. The invention addresses the problem of allowing all network users at least some network resources during emergency and other similar situations. The invention transfers filters used for communications from guaranteed bit rate radio bearers to non-guaranteed bit rate radio bearers upon indication of emergency or other similar situations.

Abstract: A system of access control in a data communication network comprising of a privacy unaware Guest Device, a privacy unaware Slave device, a PN Server and a Master Device wherein the access of a privacy unaware Slave device by a privacy unaware Guest Device is restricted by a PN Server, which intercepts all session initiations concerned with the Slave Device. A method of access control of the system comprises the steps of Access request by Guest Device privacy mode processing by PN Server privacy decision processing by Master Device; and privacy response processing by PN Server.
