An access radio port is provided that includes means for spreading a payload data signal, extracted from an ATM packet, with a uniquely assigned orthogonal code, means for transmitting the spread payload data signal to one of a group of mobile subscriber terminals located within a microport cell of a wireless terrestrial network, and means for releasing the uniquely assigned orthogonal code. In another aspect, a mobile subscriber terminal, configured to be located within a microport cell of a terrestrial wireless network that interfaces with an access radio port, is provided. The mobile subscriber terminal includes means for receiving an assignment of a unique orthogonal code, means for spreading a payload data signal by the unique orthogonal code, means for modulating and forwarding the spread payload data signal to the access radio port, and means for releasing the assignment of the unique orthogonal code.

What is claimed is: 1. An access radio port of a terrestrial wireless network that is coupled to a packet network, comprising: means for receiving one or more packets having a destination address that corresponds to a particular mobile subscriber terminal out of a plurality of mobile subscriber terminals; means for assigning an orthogonal code, gi, to the particular mobile terminal that corresponds to said destination address; means for creating an outgoing message comprising payload information of said one or more packets, and terminated with an end-of-message flag; means for spreading the outgoing message with said gi orthogonal code and an orthogonal code, ωi, that is assigned to said access radio port to form a twice spread message; means for transmitting the twice spread message over the wireless terrestrial network; and means for releasing the gi orthogonal code following transmission of the spread end-of-message flag when a negative acknowledgement fails to arrive within a preselected time interval. 2. The access radio port of claim 1, further comprising: means for transmitting a data indication signal to the particular mobile subscriber terminal over a channel different from a channel for transmitting the twice spread message prior to the transmission of the twice spread message by the means for transmitting the twice spread message, which data indication channel is spread with a paging spreading code, ωj, of said access radio port. 3. The access radio port of claim 2, wherein the data indication signal identifies said gi orthogonal code. 4. The access radio port of claim 1, further comprising: means for receiving a twice spread payload data signal that comprises fast packet-switched network packets from the particular mobile subscriber terminal; and means for despreading the received payload data signal employing said gi orthogonal code and said ωi orthogonal code. 5. A mobile subscriber terminal comprising: means for wirelessly receiving from an access radio port an assignment of a unique orthogonal code; means, responsive to a subscriber signal comprising fast packet-switching network packets, for forming a message including in its payload said packets followed by an end-of-message signal; a spreader for spreading the message by the unique orthogonal code and by a PN code assigned to said access radio port; means for modulating and transmitting the spread message to the access radio port; and means for releasing the assignment of the unique orthogonal code after the spread end-of-message signal is detected. 6. The mobile subscriber terminal of claim 5, wherein the means for modulation and transmitting also transmits a preamble and a header that are spread using said PN-code.
