The present disclosure describes systems and methods for authenticating a called party during the initialization stage of establishing a secure telecommunication channel to provide assurances to the initiator that they are communicating with whom they intended. A first user issues a challenge that includes a nonce to one or more second user devices. The second user's secure collaboration application receives the challenge, signs the nonce included in the challenge, and sends the response with the signed nonce to the first user. The first user receives the response and determines whether the signature of the first nonce is valid. If the signature is not valid, the first user's secure collaboration application terminates the secure telecommunication. However, if the signature received in the response is valid, the first user's secure collaboration application begins exchanging encrypted telecommunication data with the second user over a secure telecommunication channel.

In a radio access network (10) comprising a radio network controller node (26) and a base station node (28), a code tree has spreading codes which are allocatable between high speed downlink shared (HS-DSCH) channels and dedicated (DCH) channels. According to one aspect of the technology, use of the spreading codes of the code tree is monitored and an HS-DSCH channel is allocated a free spreading code which is non-adjacent to a spreading code already allocated to the HS-DSCH channels. In some example implementations, the free, non-adjacent spreading code is allocated so that more than one high speed channel user can use the spreading codes. In other example implementations, the free, non-adjacent spreading code is allocated so that one user uses the spreading codes by using more than one HS-SCCH channel. Preferably the non-adjacent spreading code is released from the HS-DSCH channel when the non- adjacent spreading code is needed for use by a DCH channel.
