A draWback of all of the above licensing methodologies is
that the computational system is either completely enabled or
completely disabled, depending upon Whether or not a speci

the licensing protocol is not satis?ed. During system mainte

A further method is to freely distribute CD-ROM disks.
When the CD-ROM is inserted into a computer, the computer

loWer limit value is never greater than the upper limit value.
When duplicated processors are used such as shoWn in
FIG. 1, a separate license ?le can be saved for each processor
or a common license ?le for both processors. Because dupli
cated processors share translation, typically only one copy of
the license ?le is installed, though the ?le is saved to tWo ?ash
cards (one for each processor). If either of the tWo processors
is replaced, the license ?le must be replaced.
Referring again to FIG. 1, a remote feature activation sys
tem 109 generates the license ?le that is transmitted to the
sWitching system 100 upon installation or provisioning of the
system. Remote feature activation system 109 is discussed in
con?guration of the system 100. In the LICENSE-ERROR
mode, the telecommunication application is permitted to run
for a predetermined period of time or grace period. License
error timer 126 (FIG. 1) is used to monitor the grace period.
Each timer 12611-11 is maintained by a corresponding telecom
munication application in memory. In order to preserve the
timer value across reboots, timer values 12511-11(each of
Which corresponds to a timer 12611-11) are saved once every
hour in nonvolatile memory. The application 114 reads the

Modern 108 is directly connected to control processor 102
so that control processor(s) 102 can contact remote feature
activation system 109 via public telephone netWork 104.
Similarly, remote feature activation system 109 can establish
a communication channel With control processor 102 via

The request is received by the license manager 113 in step
400 of FIG. 4A. The license manager 113 decrypts the request
and in response to the encrypted message attempts to open,
decrypt, and read the license ?le 112 in step 404. In step 408,
the license manager determines Whether or not the license ?le
is present and valid. This query determines Whether there is a
license ?le available, Whether the license ?le is readable, and
Whether the license ?le is in the proper format. If any one of
US 7,698,225 B2

these checks has a negative result, the manager 113 concludes
that the license ?le is invalid. When the license ?le is invalid,
When the license is denied, the manager 113 generates a
license denied response in step 472. The response includes an
indication that the license is denied, the error code(s) corre

and proceeds to step 472 (discussed below).
In step 416, the manager 113 reads license ?le 112 to obtain
the list of permitted features, name and/ or version number of
mask. The feature mask is not returned if the error is “no valid
license present” since there is no feature mask to return With
out a valid license. When the license is denied for more than

license ?le is stored in an encrypted form. As Will be appre

keys. The manager 113 then determines Whether or not the

encrypted and forWarded to the mode setting agent 124.
Referring again to FIG. 3, the mode setting agent 124 in
step 304 receives the encrypted license response from the
manager 113 and decrypts the response. As discussed beloW,
the mode setting agent 124 parses through the various ?elds

In step 424, the manager 113 forWards a serial number

cally readable serial number that is set during board manu

the serial number request after a predetermined time period
and/or after a predetermined number of requests, manager
113 assumes that the processor 102 is unavailable. It is typi
cally desired to resend serial number requests in the event that
no response is received, as the processor may be resetting
(e. g., after a ?rmware update) at the time of the initial serial
25

In step 428, the manager 113 determines Whether each of
the processors 102a and 10219 has responded and is therefore
present. If not, the manager 113 in step 432 records the proper
error code for the corresponding unavailable processor.
In step 436, the manager 113 determines if the serial num

ber.
In the event that the duplication ?ag is off or after either of
steps 448 or 452, the manager 113 determines in step 456
Whether or not the license is expired. When the expiration
date in the license ?le is earlier than the current date and time,
the license is considered to be expired. When the license is
expired, the manager 113 in step 460 records the proper error
code for an expired license.
In step 464, the manager 113 decides Whether the license is

mode, the corresponding license timer value saved is Zero.
At initialization or any other time that the value is not
available in memory, the agent issues a timer request to the
license manager 113. To generate a timer response, the man
ager 113 queries each of the processors for the stored timer
value. The loWest of these values (the value closest to expi
ration) is passed back to the agent in the timer response

license is granted When no error codes are recorded.
When the license is granted, the manager 113 generates a

proceeds to step 320 in Which the mode is set to the NO

In step 508, the license manager performs a series of
checks to determine if the license ?le is valid. The license
manager con?rms that the serial number contained in the

that the license has not expired, that the version contained in
the license ?le matches the softWare version loaded onto the

agent proceeds to step 316 (in Which the license mode is set to
the LICENSE-ERROR mode). When the serial number(s)
match, the agent proceeds to step 344.
The agent in step 344 next determines if the manager found
that the feature limits Were being exceeded. When the limits
are being exceeded, the agent proceeds to step 316. When the
limits are not being exceeded, the agent proceeds to step 348.
In step 348, the agent determines Whether the manager

perform all or part of the licensing-related functions of the
license manager.

changes Would be permitted, then after a couple of days,
displays Would stop Working, and then after a couple of more
days outbound calls Would be blocked. This behavior Would
give the customer a better Warning regarding the impending
loss of service.
