requirement.
Not required for Verizon Carrier.
90.2
TCP/IP
Via the AT commands it’s possible to access the TCP/IP functionalities. For more details about AT
commands see the u-blox C200 AT Commands Manual [3].
90.2.1
Multiple PDP contexts and sockets
Two PDP context types are defined:
“external” PDP context: IP packets are built by the DTE, the MT’s IP instance runs the IP relay
function only
“internal” PDP context: the PDP context (relying on the MT’s TCP/IP stack) is configured,
established and handled via the data connection management packet switched data
commands described in u-blox C200 AT Commands Manual [3]
Multiple PDP contexts are supported. The DTE can access these PDP contexts either alternatively
through the physical serial port, or simultaneously through the virtual serial ports of the multiplexer
(multiplexing mode MUX), with the following constraints:
Using the MT’s embedded TCP/IP stack, only 1 internal PDP context is supported. This IP instance
supports up to 7 sockets
Using only external PDP contexts, it is possible to have at most 3 IP instances (with 3 different IP
addresses) simultaneously. If in addition the internal PDP context is used, at most 2 external PDP
contexts can be activated
Secondary PDP contexts (PDP contexts sharing the IP address of a primary PDP context) are also
supported. Traffic Flow Filters for such secondary contexts shall be specified according to 3GPP TS
23.060 [8].
At most 2 secondary PDP contexts can be activated, since the maximum number of PDP contexts,
both normal and secondary, is always 3.
