摘要： The invention relates to a method for service aware scheduling of wireless resources in a wireless network. According to the inventive method, a service request for service delivery of a service type is received (51). A performance to value relationship for the service type is determined (52) and approximated (53) with a scheduling weight function associated with the service type. Previous performance for service delivery related to this service request is evaluated and approximated with a performance estimate (54). A scheduling weight is determined (55) by introducing the performance estimate in the scheduling weight function. Resource scheduling is performed (58) following a step of comparing (56) scheduling weights for on-going service requests. The invention also includes a network node and a system for service aware scheduling of wireless resources in a wireless network.

摘要： In a method and a device for automated compensation for a cell/sector outage parameters of uplink power control are adjusted in order to tradeoff coverage versus quality. The uplink power control parameters can be continuously optimized in response to traffic and network characteristics thereby providing for an optimized performance degradation in cells surrounding the coverage hole.

摘要： The invention relates to a method and arrangement (500) in a network communication node (13, 14) for adapting an amount of periodic resources. The periodic resources are semi statically configured to a user equipment (11, 12) within a cell (10) of a radio telecommunications network (1). The network communication node (13,14) is comprised in the radio telecommunications network (1) and controls an amount of radio channel resources within the cell (10) of a radio control channel. The amount of periodic resources is defined as a size of a control region, which control region is at least a part of the amount of radio channel resources. The user equipment (11,12) uses a specific control signalling type on the radio control channel. The network communication node determines a traffic load in the cell (10) and obtains a periodicity requirement indication, which indication is based on the control signalling type. The network communication node then determines the size of the control region based on the determined traffic load in the cell (10) and the obtained periodicity requirement indication and thereby adapts the amount of periodic resources for the cell (10).

摘要： In one of its aspects the technology concerns a method of operating a telecommunications system (10) comprising a serving radio base station (50S) and a candidate radio base station (50C). The serving radio base station (50S) comprises a radio base station to which a wireless mobile station (30) provides measurement reports. The serving radio base station (50S) and the candidate radio base station (50C) are different with respect to at least one of frequency and radio access technology. The method comprises the serving radio base station (50S) allowing the mobile station (30) to obtain information broadcasted by the candidate radio base station (50C). The information is either information for locating Cell Global Identity (CGI) of the candidate radio base station (50C) or the Cell Global Identity (CGI) itself of the radio base station. The mobile station (30) obtains the information from the candidate radio base station (50C) during at least one reading gap. The reading gap is a time period in which the mobile station (30) does not receive information from the serving radio base station (50S).

摘要： A device (130) obtains a service change associated with a cell (410-2) in a radio network (100), and identifies helper cells (410-1/410-3) in the radio network (100) that need new random access channel (RACH) parameters due to the service change. The device (130) also determines a RACH parameters configuration for the helper cells (410-1/410-3), and configures the helper cells (410-1/410-3) with the determined RACH parameters configuration.

摘要： In a method and system for automatically bringing a cell into DTX mode, a time period is introduced during which the outcome of bringing a cell into DTX mode is observed. The cell can return to a transmission mode if the outcome is non-satisfactory as determined by some criteria. Hereby an improved automated DTX method can be implemented which helps save energy in a cellular radio system.

摘要： The present invention relates to a method and a communication network node for automatically tuning a PRACH configuration parameter in a communication network system comprising radio base stations each serving at least one cell and with which user equipments are communicating on uplink and downlink channels. The PRACH configuration parameter is used for defining the division of uplink resource blocks between PRACH and PUSCH. Load statistics on RACH and PUSCH are collected used for determining a number of RACH opportunities required per time unit. Then a new PRACH configuration parameter having said required number of RACH opportunities per time unit is selected which is replacing the old PRACH configuration parameter.
