摘要： The present invention relates to methods and arrangements in a network node such as a positioning server and a user equipment of enabling downlink-based positioning of the user equipment which is served by a serving cell. The network node estimates (210) a timing difference between a timing of a neighboring cell and a timing of the serving cell. This is done based on synchronization information associated with the neighboring and serving cells. It then transmits (220) an instruction to perform a positioning measurement to the user equipment. The instruction comprises an identity of the neighboring cell and the estimated timing difference. In this way the UE may find the reference signal when performing the positioning measurements, even when the SFNs of the neighbor cell is not aligned with the SFN of the serving cell.

摘要： A radio access network (11) facilitates transmission of a Multimedia Broadcast/Multicast Service to plural user equipment units served by a radio base station. A radio network controller node (26) includes in a first message (70) of a Common Transport Channel Setup procedure an indication that sharing of a common transport bearer (60) involved in a session of the Multimedia Broadcast/Multicast Service is allowed. A radio base station (28) makes a determination whether to share the common transport bearer (60) among user equipment units (30) situated in plural cells (C) served by the radio base station (28). If the determination is positive, the radio base station (28) includes in a second message (80) of the Common Transport Channel Setup procedure an identification of an already-established channel to be used as the shared common transport bearer. The radio network controller (26) then uses the already-established channel as the shared common transport bearer for transmitting Multimedia Broadcast/Multicast Service user data to user equipment units (30) situated in plural cells served by the radio base station.

摘要： Systems and methods that provide improved success rates for connection reestablishments in a cellular communications system are disclosed. Embodiments of a radio access node in a cellular communications system enabling connection reestablishment for a wireless device to a target cell controlled by the radio access node are disclosed. In some embodiments, the radio access node is operative to: (a) perform a wireless device context fetch for a context for the wireless device from two or more candidate source cells of the wireless device in response to a connection reestablishment request from the wireless device and (b) receive a wireless device context from at least one of the two or more candidate source cells of the wireless device in response to performing the wireless device context fetch. By performing multiple context fetches, the radio access node mitigates the problem of physical cell identifier ambiguity.
