Abstract:
1. An apparatus to process a data call in a private evolution data only wireless network system, the apparatus comprising: a relay unit to relay a unicast access terminal identifier request message in response to a unicast access terminal identifier request message from a terminal entering the private evolution data only wireless network, the unicast access terminal identifier request message including a public network unicast access terminal identifier allocated in a public evolution data only wireless network; a call processing unit to generate a new private evolution data only wireless network unicast access terminal identifier request signal in response to the unicast access terminal identifier request message from the relay unit, and to close a session created at the terminal and the public network according to the received message in response to a received unknown unicast access terminal identifier response message corresponding to the unicast access terminal identifier request signal, and to relay a new unicast access terminal identifier request message from the terminal through the relay unit, the new unicast access terminal identifier request message including random unicast access terminal identifier information, and to send an authentication request signal to the connection terminal through the relay unit in response to a private network session being established with the terminal according to a newly allocated unicast access terminal identifier; and a session information processing unit to send a unicast access terminal identifier response message to the call processing unit in response to the private evolution data only wireless network unicast access terminal identifier request signal from the call processing unit, and to allocate the new unicast access terminal identifier to the connection terminal according to the relayed new unicast access terminal identifier request message from the call processing unit to establish the private evolution data only wireless network session with the terminal, and to then store the established session information in a database thereof.
