摘要:
Aspects of the present invention relate to improved systems and methods for handing over a UE from a source node to a target node. In some embodiments, the target node receives UL and DL count information directly from the UE being handed over, rather than from the source node or from a core network node.

In a method of managing radio link failure based on the RRC protocol in a user equipment node communicating over a radio link with a radio base station node in a wireless communication system, the user equipment node detecting (S10) a radio link failure. Subsequently, the user equipment node transmitting (S20) a RRC connection reestablishment request for the failed radio link, and receiving (S30) a RRC connection reject message together with redirection information indicating an alternative radio link to another radio base station node. Finally, the user equipment transmitting (S40) a RRC connection request based on the redirection information to the other radio base station node.

Method in a network node (110) comprised in a wireless communication system (100), for adjusting size of a cell (115) served by the network node (110). The method comprises estimating (304) a parameter value, related to a number of unsuccessful network connection attempts made by one or more user equipment (120) during a measurement period, and/or a number of dropped user equipment connections to the network node (110) during the measurement period. Further, the method comprises comparing (305) the estimated (304) parameter value with a threshold value, and adjusting (306) the size of the cell (115), based on the result of the comparison (305) of the estimated (304) parameter value with the threshold value.

The present invention relates to a method in the radio access node for paging user equipment attached to a radio network. The steps performed by the radio access node include receiving (31) a core network paging message from a core network. A request for paging of the user equipment in a set of neighboring radio access nodes using paging level information in the core network paging message is identified (32), wherein the paging level information may include information that an escalated page is to be performed. A radio access node paging instruction is generated (33) in the radio access node receiving the paging message; the paging instruction including an escalated page instruction. The paging instruction is sent (34) to the set of neighboring radio access nodes, whereupon a page is initiated in at least one cell of each neighboring radio access node. The invention also relates to a radio access node configured to perform the inventive method.

The invention relates to a method in a first radio base station for determining a performance state of a first cell served by the first radio base station, which first radio base station is comprised in a radio communications network. The method comprises determining traffic statistics of the first cell, comparing the traffic statistics with a threshold value, when the determined traffic statistics goes beyond the threshold value, transmitting a data request to a second radio base station requesting data retrieved in or associated with a second cell to be used to determine performance state of the first cell, receiving a data response indicating the requested data from the second radio base station, and determining the performance state of the first cell based on the data response.

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.

Embodiments herein relate to a method in a first communication device with an adaptive neighbouring cell relations function. The first communication device receives (42) a measurement report of a possible neighbouring cell candidate of a second communication device from a user equipment camped/connected within a first cell served by the first communication device and determines (44) to set up an inter node connection to the second communication device serving the possible neighbouring cell candidate indicated in the received measurement report. The firs communication device then initiates (46) to set up the inter node connection to the second communication device by sending a connection request comprising a geographical position of the first communication device.
