1. A method of communication between end devices connected to a telecommunications network, the network comprising a local network access point to which an initiating end device is connected, and a remote network access point to which a remote end device is connected the method comprising:

  • selecting, a first session identifier (session ID) from a first array comprising at least one assignable session ID;

    storing first session ID at the network access point;

    forwarding, from the initiating end device to the local network access point, a remote end device identifier, indicative of the identity of a remote end device with which the initiating end device is to communicate;

    updating an initiating end device table with the remote end device identifier and with the first session ID; and

    transferring data as a plurality of packets each of which contains the first session ID;

    wherein the method further comprises;

    sending the first session ID along with an identification of the said remote end device to the said remote network access point;

    allocating at the said remote network access point, a second session ID from a second array comprising at least one assignable session ID;

    updating a remote network access point table with the allocated second session ID such that the said first and second session IDs are mapped to one another;

    and forwarding the said second session ID to the remote end device;

    the step of transferring data as a plurality of packets further comprising;

    transferring each packet between the initiating end device and the remote network access point via the local network access point along with the said first session ID, and transferring each said packet between the remote fixed access device and the remote end device using the mapping of the said first to the said second session ID.
