Abstract: A method is performed in a network node of a mobile communication network, for determining a dropped connection to a mobile terminal. The method comprises: detecting a release of a radio bearer associated with the mobile terminal; determining whether the radio bearer is a real-time type radio bearer; when the radio bearer is a real-time type radio bearer, determining the released radio bearer to be a dropped connection when the release is classified as an involuntary release; and when the radio bearer differs from a real-time type radio bearer, determining the released radio bearer to be a dropped connection when there is remaining user data in a buffer for transfer in either direction over the released radio bearer. A corresponding network node, computer program and computer program product are also presented.

Abstract: Methods, apparatus, and systems for measuring, on a per-QoS-class basis, the average number of user devices active on the uplink of a wireless communication system are disclosed. In an exemplary method, a number of mobile terminals with buffered data for transmission to a base station is estimated based on received buffer status reports. An estimated quantity of active mobile terminals is calculated, based on the received buffer status reports and a number of mobile terminals for which a semi-persistent scheduling grant has been granted. In some embodiments, the estimated quantity of active mobile terminals is estimated on a per-traffic-class basis, in which case the technique includes calculating first and second estimated quantities, corresponding to mobile terminals having active data bearers for first and second traffic classes, respectively, based on the received buffer status reports and the number of mobile terminals for which a semi-persistent scheduling grant has been granted.

Abstract: The present invention is a method and system adapted to facilitate, between a mobile station (MS) and network, an indication of support for reduced time transmission interval (RTTI). The MS can provide a base station system (BSS) with an indication of its multislot capability within an access burst sent at the start of a contention based access. In another aspect, the MS can indicate support for a new Immediate Assignment message as the conventional Immediate Assignment message can only assign single timeslots. The present invention enables the Radio Access Network (RAN) to assign RTTI and more than one timeslot for GPRS/EDGE temporary block flows (TBFs) during an Access Grant Channel (AGCH) assignment. The method of the present invention can be implemented in a computer program product or distributed software adapted to be loaded into at least one or a plurality of memory locations and executed by at least one or a plurality of respective computer processors.

Abstract: A method in a base station (120) for determining an integrity of an air interface (145) between the base station (120) and a user equipment (130) is provided. The base station (120) configures an internet protocol host. The internet protocol host has an internet protocol address in the same domain as an internet protocol address of the user equipment (130). The base station (120) defines a data radio bearer which is limited to the air interface (145). The base station (120) sends a test data in the defined data radio bearer on an internet protocol level from the first internet protocol address to the second internet protocol address. The base station (120) receives a response associated with the test data from the user equipment (130). The base station (120) determines an integrity of the air interface (145) based on the response.

Abstract: Methods and apparatus relate to cellular communications and in particular to a frequency spectrum shared by two cellular networks. An object is flexible utilization of the spectrum. This is achieved by a method where a first of the networks occupies part of the shared spectrum in relation to the traffic load in the first network. The first network informs a second of the networks on the extent the shared spectrum is occupied, for the second network to be free to use the shared spectrum outside the occupied part. A radio resource management unit, a base station controller, and a radio base station are also disclosed. An advantage is that spectrum can be lent from an old system when a new system is introduced.

Abstract: A telecom node (210, 310) such as a base station is configured to detect events. A low priority event may not be serious enough on its own to raise an alarm to a network management system (220, 420) managing the telecom node (210, 310). However, the low priority event can collectively have a serious impact on the network performance if the event occurs over multiple nodes (210, 310) of the network (200). When a low priority event occurs over multiple nodes (210, 310), the telecom node (210, 310) notifies the network management system (220, 420) of the event by raising an alarm so that the situation can be addressed. In a partitioned network installation, not all neighboring nodes (210, 310) are managed by a same network management system (220, 420). When the alarm is raised to the network management system (220, 420), other network management systems (220, 420) managing the neighboring nodes (210, 310) are notified of the alarm by the network management system (220, 420).

Abstract: In one embodiment, if a UE is performing minimizing drive test (MDT) measurements and a radio link failure (RLF) occurs, the UE may add MDT measurement information to an RLF message to the network. In effect, the UE “piggy-backs” MDT information in the RLF report, and in so doing, provides greater flexibility to UEs reporting MDT information and more robust reporting. In another embodiment, the UE detects that no allowed reporting channel to report MDT measurement information exists, stores the MDT information, and after detecting that allowed reporting channel exists, initiates establishment of a radio link with the radio communications network during which the UE informs the network using an availability indicator that the UE has stored unreported MDT measurement information to be reported to the radio communications network.
