ABSTRACT:
BACKGROUND OF THE INVENTION
1. Field of the Invention
The invention relates generally to wireless modems, and more particularly to remote management of a wireless modem.
2. Background
Existing GSM modems operate, for setup and control purposes, similarly to known landline modems, such as Hayes compatible modems. Such modems generally act primarily as a transport mechanism for moving data between two devices, such as a client computer and a head-end server. In particular, the modem is configured to passively modulate data or control signals from the client computer or to passively push modulated signals through the modem to the client computer.
When a modem is initialized, it will generally run either from a default modem configuration, which is stored in the modem, or the modem will receive a special initialization configuration parameters from the client computer. The initialization configuration is performed, in either mode, to ensure that the modem is able to communicate with the client computer and, preferably, operate (as a transport) at its maximum efficiency.
FIG. 1
shows a typical communication network
100
employing a wireless modem. A laptop computer is the client computer
104
. The client computer
104
is connected, for example through an RS-232 port and serial cable
106
, to a GSM modem
108
. In turn, the GSM modem
108
is coupled to a GSM network
112
via over-the-air interface
110
. The GSM network
112
is coupled to a head-end server
116
, such as an application server, via a short message service center interface
114
.
As data flow
150
illustrates, when a client computer
104
tries to connect to the head-end server
116
, it will first try to initialize the GSM modem
108
by passing configuration parameters directly to the GSM modem
108
. For example, configuration parameters
120
are passed to the GSM modem
108
over the serial cable
106
from the client computer
104
. A response
124
, indicating whether the parameters were accepted, is then sent by the GSM modem
108
back to the client computer
104
. Once the GSM modem
108
is initialized, it essentially becomes a slave to the client computer
104
and functions as a passive transport carrying data
128
from the client computer
104
to the head-end server
116
, in addition to data
132
from the head-end server
116
to the client computer
104
.
SUMMARY OF THE INVENTION
An operator independent, transparent wireless modem management system is disclosed. According to an embodiment of the invention, the modem management system comprises the steps of receiving a short message service message at the wireless modem and examining the short message service message for modem management information. If the short message service message comprises modem management information, then the wireless modem processes the short message service message.
A wireless modem is also disclosed, the wireless modem comprises electronic hardware and software for implementing a wireless protocol. A processor in the wireless modem is preferably configured to handle signals from an external device over an interface, and is also configured to handle one or more short message service messages delivered over a RF transceiver, the short message service messages comprising modem management information.
