Abstract: A method and a radio network node for managing a request for a radio access bearer. The radio network node determines a first value relating to utilization of radio resources in a first set of subframes. The first set of subframes includes a second set of subframes, dedicated for transmission by the radio network node to multiple radio communication devices, and a third set of subframes. The radio network node determines a second value relating to utilization of radio resources in the third set of subframes. The radio network node receives the request and obtains an indication relating to a capability of a radio communication device to receive transmission in one or more of the second set of subframes. The radio network node determines a response to the request based on the first value, the second value and the indication, and sends the response to the network node.

Abstract: A network node determines a system load of the network node for the UE. When the UE is capable of receiving control information on EPDCCH, the system load is determined based on a first and a second system load metrics on a physical resource shared by PDSCH and EPDCCH, which first load metrics comprises a load due to EPDCCH and a load due to multiplexed PDSCH and which second load metrics comprises a load due to multiplexed EPDCCH and a load due to PDSCH. When the UE is not capable of receiving control information on EPDCCH, the system load is determined based on the first system load metrics on the physical resource shared by the PDSCH and EPDCCH and a third system load metrics on a physical resource for carrying PDCCH. The network node further determines whether or not to allocate resources to the UE based on the determined system load metrics.

Abstract: A method for determining a priority of a mobile subscriber in a cellular network. The method is performed in a radio network node and comprises the steps of: obtaining a temporary mobile subscriber identity, TMSI, associated with a priority affecting event; storing the TMSI associated with the event, as at least part of an indication of priority; receiving a connection request from a wireless terminal of the mobile subscriber, the connection request comprising a TMSI; and determining a priority of the wireless terminal based on whether the TMSI of the connection request matches a stored TMSI or not.

Abstract: Network node (110) and method (600) in a network node (110), for admission control of a request for a radio access bearer to be received from a user equipment (120). The method (600) comprises monitoring (601) the achievement of quality of service requirement of an admitted radio access bearer, detecting (602) when the quality of service requirement of the admitted radio access bearer is not achieved, assessing (603) a reason why the quality of service of the admitted radio access bearer is not achieved, and determining (604) admittance of a further request for radio access bearer, based on the reason why the quality of service of the admitted radio access bearer is not achieved.

Abstract: The invention relates to a network node and a method therein for admission control in a wireless communication system. The method comprises receiving a request for a bearer setup from a requesting entity, where the request and/or bearer is associated with a priority level P. The method further comprises obtaining, e.g. receiving or retrieving, reports indicating a priority blocking level, BLi, per monitored system resource, i, needed for setting up a bearer. The method further comprises determining a general priority blocking level BLG, based on the reports. Further, the method comprises deciding whether to accept or reject the request for a bearer setup based on the priority level P and the general priority blocking level BLG.

Abstract: A method of operating a radio access node for a wireless communications network includes the steps of obtaining a minimum transfer bitrate for a transfer of data content between the radio access node and a wireless communications device, and scheduling one or more radio resources for the transfer of the data content based on the minimum transfer bitrate. The minimum transfer bitrate is calculated based on a total volume of the data content and a transfer deadline for the transfer of the data content.

Abstract: Network node and method therein for admission control in a communication system applying shared channels for communication. The method comprises receiving a request for a bearer setup, and deciding whether to accept or reject the request for a bearer setup based on information on current bearers carrying data having a QoS value, and for which bearers a transmission of the data fulfills a criterion, the criterion representing a probability of violating the QoS value. Information on bearers carrying data which do not have a QoS value and information on bearers for which a transmission of data having a QoS value does not fulfill the criterion is disregarded.

Abstract: Herein are described a number of network nodes and methods therein for handling radio resources. The method to be performed by a base station, BS, comprises receiving an Initial Context Setup message from an MME as part of a Service Request procedure, where the Initial Context Setup message comprises information indicating which at least one EPS bearer, out of a number of EPS bearers associated with a UE, that has triggered initiation of the Service Request procedure. The method further comprises deciding whether or not to allocate radio resources for the requested service based on a priority value associated with the at least one indicated EPS bearer; and allocating radio resources for the requested service in accordance with the decision.

Abstract: Network node (110) and method (600) in a network node (110), for admission control of an additional radio access bearer based on load of control channel elements on a control channel, assigned by a scheduler (700) comprised in the network node (110). The method (600) comprises assigning (601), by the scheduler (700), control channel elements on the control channel for already admitted radio access bearers. Further, a first and a second load of the control channel is computed (606, 607) based on the usage of assigned control channel elements subframes on which both downlink assignments and uplink grants are enabled, and on which downlink assignments are enabled, respectively. If any of the first or second loads exceeds a respective threshold value, the radio access bearer to be admitted is rejected (609A).

Abstract: A set of radio resources are allocated to a first user equipment (110). The radio network node (130) receives a request for radio resources from a second user equipment (120) being associated with a first or second category. Furthermore, the radio network node (130) measures an inactivity time period of the first user equipment (110). Then, the radio network node (130) releases the set of radio resources when the inactivity time period exceeds a threshold to be applied dependent on the category of the request. The releasing of the set of radio resources is triggered by the request.

Abstract: A method and apparatus for dynamically allocating a time delay indicator value and/or random access parameters for sending to a mobile terminal during a Random Access procedure. The time delay indicator value indicates a time delay during which the mobile terminal is restricted from attempting a further Random Access procedure. At least one factor relating to monitored network conditions is determined. The time delay indicator value and/or other random access parameters are allocated on the basis of the factor. The time delay indicator value and/or random access parameters are then sent to the mobile terminal. This ensures that time delay indicator values can be dynamically adjusted depending on network conditions.
