    • A first radio base station (RBS) is operated to cause trace log information to be supplied to a trace log storage node. The RBS becomes responsible for serving a user equipment session, and at some point begins a trace process. When the session report criterion has been satisfied, a trace status indication is alternatively sent to or received from a second radio base station, the trace status indication including an indicator of a session report cause and a time of satisfying the session report criterion. The indicator of the session report cause and the time of satisfying the session report criterion are used to identify a set of trace log information stored in a record buffer. If not empty, the set of trace log information is supplied to the trace log storage node.
    • 操作第一无线电基站(RBS)以将跟踪日志信息提供给跟踪日志存储节点。 RBS负责服务用户设备会话,并且在某些时候开始跟踪过程。 当满足会话报告准则时,跟踪状态指示交替地被发送到第二无线电基站或从第二无线电基站接收,跟踪状态指示包括会话报告原因的指示符和满足会话报告标准的时间。 使用会话报告原因的指示符和满足会话报告标准的时间来标识存储在记录缓冲器中的一组跟踪日志信息。 如果不为空,则将跟踪日志信息集提供给跟踪日志存储节点。

    • Cell outage within a wireless communication network is automatically mitigated. This way, neither manual operator intervention nor manual base station reconfiguration is needed to cover problematic cells. Quality of wireless services provided by the network improves when cell outage is automatically mitigated. In one embodiment, cell outage is mitigated in a wireless communication network by automatically communicating cell status messages between radio base stations or within a node that controls the radio base stations (300) indicating whether one or more cells within the network are currently disabled or expected to be disabled. The coverage area of one or more preexisting cells is modified to cover those cells which are currently disabled or expected to be disabled as indicated by the cell status messages (302). The inter-base station interface can also be used to send messages directly between the base stations indicating addition of new cells or deletion of preexisting cells.
    • 无线通信网络中的蜂窝中断被自动减轻。 这样,无需手动操作员干预,也不需要手动基站重新配置来覆盖有问题的单元。 网元提供的无线服务质量可以在细胞停电自动减轻时得到改善。 在一个实施例中,通过在无线电基站之间或在控制无线电基站(300)的节点内自动传送小区状态消息来指示网络中的一个或多个小区当前是否被禁用或预期的,在无线通信网络中减轻了小区中断 被禁用 修改一个或多个预先存在的单元的覆盖区域以覆盖目前被禁用或期望被禁用的那些单元,如单元状态消息(302)所指示的。 基站间接口还可用于在基站之间直接发送消息,指示添加新小区或删除预先存在的小区。

    • 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.

    • A method for downloading a multimedia file from a server (101, 201, 300, 701) to a user device (100, 200, 400, 700), at least partly via a bandwidth limited connection (202, 702), a server and a user device adapted therefore. A user device, connected to a server selects a multimedia file to be downloaded via two bit streams. In the server the selected multimedia file is divided and coded into a first, low-quality part, and into a second, high-quality part (503). When certain conditions (505) set up for the first part are fulfilled, this part is streamed via a first bit stream (506), and when certain conditions set up for the second part are fulfilled, the second part is downloaded via a second bit stream (508). In the user device, the first part is received and reproduced (603b) as a limited version, available to be played-up in real time (604), while the second part is reproduced and combined with the first part (610, in order to yield the original multimedia file.
