    • The invention relates to a method in a first radio base station (10) for determining a performance state of a first cell (12) served by the first radio base station (10), which first radio base station (10) is comprised in a radio communications network. The method comprises determining (201,301,401 ) traffic statistics of the first cell (12), comparing (202,302,402) the traffic statistics with a threshold value, when the determined traffic statistics goes beyond the threshold value, transmitting (204,303,403) a data request to a second radio base station (14) requesting data retrieved in or associated with a second cell (16) to be used to determine performance state of the first cell (12), receiving (208,306,404) a data response indicating the requested data from the second radio base station (14), and determining (209,307,405) the performance state of the first cell (12) based on the data response.

    • A control node (140; 150) of a cellular network establishes one or more control plane sessions with a gateway node (160). On the basis of these one or more control plane sessions with the gateway node (160), the control node (140; 150) also establishes one or more control plane sessions with one or more radio access network nodes (112, 114; 122, 24) to control multicast transmissions by the one or more radio access network nodes (112, 14; 122, 124). Further, the control node (140; 150) detects a connection failure to the gateway node (160). When detecting the connection failure, the control node (140; 150) starts a first timer. Further, also the gateway node (160) detects the connection failure. When detecting the connection failure, the gateway node (160) starts a second timer. The second timer is configured with a longer duration than the first timer. In response to expiry of the first timer, the control node (140; 150) locally deletes the one or more control plane sessions with the gateway node (160) and with the one or more control plane sessions with the one or more radio access network nodes (112, 114; 122, 124). In response to expiry of the second timer, the gateway node (160) triggers a reaction to the connection failure by the gateway node (160), e.g., selection of an alternative control node.
    • 蜂窝网络的控制节点(140; 150)与网关节点(160)建立一个或多个控制平面会话。 基于与网关节点(160)的这些一个或多个控制平面会话,控制节点(140; 150)还建立与一个或多个无线电接入网络节点(112,114; 122, 24)以控制所述一个或多个无线电接入网络节点(112,14; 122,124)的多播传输。 此外,控制节点(140; 150)检测到网关节点(160)的连接故障。 当检测到连接故障时,控制节点(140; 150)启动第一定时器。 此外,网关节点(160)也检测到连接故障。 当检测到连接失败时,网关节点(160)启动第二定时器。 第二个定时器的配置时间长于第一个定时器。 响应于第一定时器的到期,控制节点(140; 150)在本地删除与网关节点(160)的一个或多个控制平面会话以及与一个或多个无线电接入网络的一个或多个控制平面会话 节点(112,114; 122,124)。 响应于第二定时器的到期,网关节点(160)触发对网关节点(160)的连接故障的反应,例如选择替代控制节点。

    • A method in a user node for reducing signalling load in a multimedia broadcast multicast services, MBMS, network, the method comprising: receiving (301) from a network node a broadcasted system information block with information about at least one MBMS service supported by a current frequency for said service; initiating (302) a connection establishment procedure, the connection establishment procedure including one or more connection establishment messages sent between the user node and the network node to set up a connection; and during the connection establishment procedure, transmitting (303) an information to the network node in one of the one or more connection establishment messages indicating that the current frequency is a frequency of interest for the user node.

    • A method is suggested for allowing a user equipment to determine whether Service Area Identities (SAIs) of a list of SAIs are current SAIs or neighboring SAIs by: receiving a list of SAIs from a network node, where the list is indicative of Service Areas capable of providing the broadcasted service to the user equipment and comprise at least one current SAI and at least one neighboring SAI; identifying, in the list, the SAIs as arranged into two distinguishable groups, wherein a first group comprise the at least one current SAI and a second group comprise theat least one neighboring SAI, and distinguishing, based on the arrangement of the list, current SAIs from neighboring SAIs.A method is also suggested for arranging a SAI list into the two distinguishable groups by a network node.
    • 提出了一种允许用户设备通过以下方式来确定SAI列表的服务区域标识(SAI)是否为当前SAI或相邻SAI的方法:通过以下方式来从网络节点接收SAI列表,其中该列表指示服务区能力 向用户设备提供广播的服务,并且包括至少一个当前SAI和至少一个相邻SAI; 在列表中识别排列成两个可区分组的SAI,其中第一组包括至少一个当前SAI,第二组包括至少一个相邻SAI,并且基于列表的排列来区分当前SAI 还提出了一种通过网络节点将SAI列表排列到两个可区分组中的方法。
