    Abstract: There are provided measures for handover control for backhaul connections, said measures exemplarily including evaluation of the suitability of an access node cell in access network as target for a handover of a terminal based on delay information being indicative of an expected packet delay in a cell of the access node, wherein such delay information may be generated and/or exchanged in the access network. Said measures may exemplarily be applied for improving handover control in relay-enhanced access networks or networks that contain access nodes connected via different kinds of backhaul that can result in different end-to-end packet delays.

    Abstract: Some embodiments provide a mobile relay node, RN, (16) with complete and valid neighbor cell information. The RN (16) requests this information from a donor base station (12) upon detecting a defined condition characteristically indicating that movement of the RN (16) has rendered previously obtained neighbor cell information incomplete or invalid. The RN (16) may generate the request to identify cells (18) currently neighboring the mobile cell (20). The donor base station (12) may then provide the RN (16) information that more specifically pertains to the mobile cell's neighbors, rather than generally pertaining to the donor cell's neighbors. Other embodiments compensate for the RN's incomplete or invalid neighbor cell information. These embodiments permit the RN (16) to identify a target cell (18) with a non-unique cell identifier in a handover message sent to the donor base station (12). The donor base station (12) resolves this non-unique identifier and replaces it with the corresponding unique identifier for sending the message towards the target cell (18).

    Abstract translation: 一些实施例提供具有完整和有效的相邻小区信息的移动中继节点RN（16）。 RN（16）在检测到特定地指示RN（16）的移动已经使先前获得的相邻小区信息不完整或无效的定义条件时，从施主基站（12）请求该信息。 RN（16）可以生成用于识别当前与移动小区（20）相邻的小区（18）的请求。 捐助者基站（12）然后可以提供更具体地涉及移动小区的邻居的RN（16）信息，而不是通常属于供体小区的邻居。 其他实施例补偿RN的不完整或无效的相邻小区信息。 这些实施例允许RN（16）在发送到施主基站（12）的切换消息中使用非唯一小区标识符来识别目标小区（18）。 施主基站（12）解析该非唯一标识符并用相应的唯一标识符替换它，以向目标小区（18）发送消息。

    Abstract: Embodiments herein relate to a method in a second network node (13,14) for detecting a short stay handover of a user equipment (11) in a second cell (16) in a telecommunication system (10). The user equipment (11) is handed over from a first cell (15) to the second cell (16) and from the second cell (16) to a third cell (17) in the telecommunication system (10). The second network node sends, to a first network node (12,18), an indication in a message that a short stay handover has occurred when determined that the user equipment (11) is handed over to the third cell (17) before a time threshold, thereby enabling the first network node (12,18) to detect the short stay handover.

    Abstract: There are provided measures for proximity reporting procedures in radio access, for example in heterogeneous network environments, said measures exemplarily including sending, to a serving base station representing a source of mobility of a user equipment, a first proximity indication indicating proximity to a microcell base station representing a target of mobility of said user equipment, said first proximity indication including a carrier according to a preceding access of said user equipment to the microcell base station, and, when detecting the microcell base station on said carrier according to the preceding access fails, sending, to the serving base station, a second proximity indication indicating proximity to the microcell base station, said second proximity indication including a carrier being different from said carrier according to the preceding access. Said measures may exemplarily be applied for mobility procedures in LTE, LTE-Advanced, HSPA and/or UMTS radio access systems.

    Abstract: A method, including receiving, at a donor access node from a relay node associated with the donor access node, an identification of one or more other access nodes detected at the relay node and sending configuration information about said relay node from said donor access node to at least one of said one or more other access nodes in advance of an indication that a user equipment associated with the relay node has detected said at least one other access node, without at the same time sending said configuration information to at least one further access node that is detected by one or more other relay nodes or user equipments associated with the donor access node but not detected by said relay node. Wherein said configuration information includes information for setting up a communication with the relay node other than via a core network associated with the donor access node.
