According to an example aspect, there is provided an apparatus configured to participate in establishment of a secured protocol connection, receive over a first interface a certificate in connection with the establishment of the secured protocol connection, receive, in connection with the establishment of the secured protocol connection, over a second interface, information concerning the certificate, and compare the certificate to the information concerning the certificate.

Certificate verification

The specification and drawings present a new method, system, apparatus and software product for defining an adaptive preamble length of a preamble for a continuous connectivity transmission using a control channel, e.g., a UL (uplink) dedicated physical control channel (DPCCH), for transmitting the preamble. Such a preamble would reduce the accuracy requirement for the initial power setting after a transmission gap and also help the channel estimation and the synchronization of a data channel, e.g., an enhanced dedicated channel (E-DCH). The preamble length can be optimized and defined using a predetermined criterion depending on: a) a degree of fading of a multipath channel which is used for transmitting data on the data channel and/or b) a throughput relative to a nominal throughput in the data channel.

Adaptive preamble length for continuous connectivity transmission

A method of providing assistance for synchronization of a radio link in a communications network comprising at least a first network element, the method comprising the steps: making a decision to connect a user equipment to the first network element via a first radio link to transmit a signal discontinuously thereto; transmitting the signal continuously from the user equipment to the first network element via the first radio link; synchronizing the first radio link; and switching the user equipment to transmit the signal discontinuously after the first radio link is synchronized.

Synchronization of radio links for a user equipment

Synchronization method for discontinuous transmissions in a communications network

A method, a device and a system for transferring data from a data source () over both a wireless communications () and a fixed communications () network to a destination device () such that at least one portion of a data aggregate is transmitted through the wireless communications network () via a wireless communications device () and at least one another portion is transmitted through the fixed communications network (). The destination device () may reconstruct the data aggregate by joining the received data portions together.
