Method and apparatus for analyzing the progress of a software upgrade on a telecommunications switch

Abstract

A method is provided for monitoring the progress of a software upgrade or retrofit on a telecommunications switch (110). A report stream of text messages relating to the state of, and events occurring on, the telecommunications switch is received by a server (102). Predetermined messages are detected in the report stream, including messages indicating entry into a stage of the retrofit, exit from a stage of the retrofit, a failure of a stage of the retrofit, alarms and errors. The time spent in a stage of the retrofit is determined and compared against an expected time (206, 210, 212). A visual portion (300, 400) of a user interface on a client (104) is updated to reflect entry and exit from a stage of the retrofit, and whether the time spent in a stage exceeds an expected time. The user interface reflects occurrences of alarms and errors visually and in some cases audibly.

Description

FIELD OF THE INVENTION

The present invention relates generally to telephone switching systems, and in particular, to a method and apparatus for analyzing the progress of software upgrades or retrofits on telephone switching systems.

BACKGROUND OF THE INVENTION

Modern telephone switching systems are large-scale, highly complex systems incorporating one or more switching elements cooperatively controlled and supervised by one or more computing means. One commercial exemplar of a modern telephone switching system is the 5ESS ELECTRONIC SWITCHING SYSTEM, from Lucent Technologies Inc., 600 Mountain Avenue, Murray Hill, N.J. 07974. The 5ESS electronic switch is a distributed switching system. Both the switching system capabilities and the control, supervision and administration capabilities are distributed. Each of the computing facilities associated with these distributed capabilities includes appropriate computer programs or software to achieve the desired operation of the switching elements and other components of the switching system.

Periodically the software or computer programs used to control the components of the switching system are replaced by different software. This replacement of computer software is referred to as an upgrade or retrofit. The process of retrofitting a telephone switching system is complex. The complexity stems from the number of distributed computing facilities; the amount of software code involved; and the fact that the switching system availability must not be completely compromised for a retrofit. A typical retrofit of a switch may take from 10 to 12 hours. Resources must be employed days in advance of the retrofit for preparation. And, of course, additional resources are required during the retrofit.

Problems occurring during a retrofit are obviously undesirable. Unfortunately, problems do occur. Some of these problems are readily fixed. Other problems prevent successful upgrade of the switch. Regardless of the nature of the problem, early detection of the problem is desirable. Early detection allows for early correction or rescheduling to avoid wasted resources.

A report data stream is produced by the 5ESS switching system containing text messages regarding the current state and recent operations of the switching system. The report data stream includes messages that (1) describe the state of the switch hardware; (2) report automatic actions taken by the switch; (3) report operations entered by a switch operator; (4) report results of routine or scheduled diagnostics; and (5) indicate non-routine events, abnormal conditions, errors or alarms. The report data stream is typically supplied to a "read-only" printer or "ROP" via a serial port. Hence, the report data stream is often referred to as the "ROP" or "ROP" report. The report data stream is voluminous, sometimes generating 4 to 5 megabytes of data for storage per day. Therefore, the ROP is often stored on a computer to permit searching and review for problem solving. In addition, a telecommunications switch owner often desires to have all ROP output from its switches collected in a single location for review.

The ROP, or its equivalent, is typically reviewed manually or with the assistance of a computer to detect problems during a retrofit of a switch. However, given the voluminous nature of the ROP, especially when considering multiple switches, this method of monitoring a retrofit is prone to miss errors and can be inefficient. Moreover, this method requires substantial subject matter expertise from a person manually reviewing the ROP.

Therefore, a need exists for a more efficient and reliable method and apparatus for monitoring the progress of a software retrofit on a telecommunications switch.

SUMMARY OF THE INVENTION

In accordance with one aspect of the present invention, a method is provided for analyzing and displaying the progress of a software upgrade on a switch. First a report stream containing a plurality of messages associated with the state of the switch is received. The plurality of messages are searched for a select set of messages that are associated with the software upgrade. The select set of messages includes at least a first message associated with an entry into a stage of the software upgrade. The select set of messages includes a second message associated with an exit from the stage of the software upgrade. Preferably, an entry message and an exit message for each stage of the software upgrade are included within the select set of messages. After a message associated with an entry into a stage is detected in the report stream, a user interface is updated to reflect the entry into that stage of the software upgrade. Similarly, when an exit message for a stage is detected in the report stream, the user interface is updated to reflect the exit from that stage of the software upgrade. Preferably, the user interface includes predetermined areas that are visually perceptible and associated with each stage of the software upgrade. Most preferably, the designated visually perceptible areas of the user interface are colored predetermined colors to reflect entry and exit from the stages of the software upgrade.

In accordance with another aspect of the present invention, messages associated with an entry into a stage of the retrofit are timed. That is, a timer is used to determine the actual elapsed time from entry message. The actual elapsed time is compared to an expected time associated with the stage. In this manner, an actual elapsed time from an entry into a stage is compared against an expected time for exit out of the stage. When the actual elapsed time exceeds the expected time associated with the stage, the user interface is updated accordingly to alert a user of a potential problem.

In addition to detecting messages associated with an entry or exit from a stage of the software upgrade, predetermined error messages are detected in the report stream. In general, these predetermined error messages reflect the occurrence of an event on the switch that should not occur during the software upgrade. Upon detection of a predetermined error message, the user interface is updated accordingly to alert a user to an error.

In accordance with another aspect of the present invention, an apparatus or system is provided for monitoring the process of a software upgrade on a telecommunications switch. The apparatus includes a report receiver, a processor, and a user interface. The report receiver receives a stream of messages from the telecommunications switch to thereby produce a received stream of messages. The received stream of messages includes messages reflecting the state of the telecommunications switch. The processor is operably coupled to the report receiver and stores the received stream of messages and searches the received stream of messages for select messages. In particular, the processor searches for select messages indicating an entry into a stage of the software upgrade or messages reflecting an exit from a stage of the software upgrade. As entry messages and exit messages are detected by the processor, a user interface coupled to the processor reflects the entry and exit from the stages of the software upgrade. Preferably, the user interface includes designated areas associated with each stage of the software upgrade and those designated areas are populated with predetermined text streams and colors reflecting entry and exit from the associated stages. Preferably, the user interface includes an audible alarm for alerting a user to certain events associated with the software upgrade, for example, alarms.

In accordance with another aspect of the present invention, the processor includes a timer that times an actual elapsed time from the receipt of an entry message, reflecting entry into a stage of the software upgrade. The actual elapsed time is compared against an expected time and the user interface is updated if the actual elapsed time exceeds the expected time. In addition to detecting messages associated with an entry or exit from a stage of the software upgrade, predetermined error messages are detected and the user interface reflects the detection of the error messages.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

FIG. 1 is a block diagram illustrating a system 100 for monitoring and analyzing the progress of a software upgrade on a telecommunications switch in accordance with the present invention. System 100 includes regional servers 102, clients 104, national server 106 and network 108. Network 108 couples national server 106 and regional servers 102 together for data communications in a manner well known to those of skill in the art. Clients 104 are shown in FIG. 1 coupled to a regional server 102 or national server 106 directly by network connections 109. Alternatively, clients 104 are directly coupled to network 108. National server 106, regional servers 102 and clients 104 are general-purpose computers programmed in a manner to implement the present invention, as described further below.

Telecommunications switches 110 are coupled to system 100 to provide system 100 with information relating to the state of the telecommunications switches 110. More specifically, each telecommunications switch 110 produces a report stream 114. Report stream 114 is a serial stream of text messages reflecting the state of the telecommunications switch 110, including error messages, alarms, and other state information. Regional servers 102 include a plurality of modems 112 that are coupled to modems 113 on switches 110. Modems 112 and modems 113 are coupled together selectively over the public switched telephone network to facilitate transmission and reception of report stream 114. The report stream 114 or ROP 114 is also transmitted to a ROP printer 116 or to a ROP spooler 118. ROP spooler 118 typically is a computer that receives ROP 114 and stores ROP 114 for future processing.

In the preferred embodiment, regional servers 102 are coupled to switches 110 to receive ROP 114 prior to a software upgrade. Most preferably, regional servers 102 are coupled to switches 110 six to eight hours prior to the beginning of the software upgrade. Regional servers 102 are preferably geographically disbursed in a region near the associated switches 110. Network 108 provides a means for regional servers 102 to communicate with each other and a national server 106. National server 106, as the name implies, is a centralized national server that is coupled to all regional servers 102. This hierarchical arrangement permits regional servers 102 to monitor switches within its associated region and then for the national server 106 to monitor all regions via connections to the regional servers 102.

National server 106 and regional servers 102 are preferably implemented as a single or multiple general-purpose computers. For example, servers 102, 106 are PENTIUM-class computers running WINDOWS NT with SERVICE PACK 5 from Microsoft Corporation.

Clients 104 are also general-purpose computers with monitors and keyboards provided for engineers and technicians to interface with system 100. For example, clients 104 are PENTIUM-class computers running WINDOWS 95, WINDOWS 98 or WINDOWS NT with SERVICE PACK 5, all from Microsoft Corporation.

FIG. 2 is a flow chart illustrating a method for monitoring and analyzing a software upgrade on a telecommunications switch in accordance with the present invention. FIG. 2 is descried below with reference to the system shown in FIG. 1.

First, the report stream from the switch being monitored is received (200). In particular, modem 112 of regional server 102 receives a stream of text messages reflecting the state of the telecommunications switch 110. The report stream contains text with certain indicia used by regional server 102 to delineate the boundaries for a message.

Server 102 searches the report stream for certain messages. In the preferred embodiment, a database on server 102 or another computer on network 108 stores definitions of certain messages that are relevant to the software upgrade. Certain streams of text found in the report stream indicate the receipt of a message. Preferably, the database is a SYBASE database available from Sybase, Inc., 6475 Christie Avenue, Emeryville, Calif. 94608-1050.

In general, the messages of interest relate to messages that must occur or should not occur during the software upgrade or retrofit. In particular, the software upgrade is delineated into certain distinct stages. In the preferred embodiment relating to the 5ESS electronic switch, the stages of the software upgrade typically include Begin, Enter, Tape, MOP, Pump SM, Pump CMP, TSMOLD, Proceed, OFLBOOT, SWITCH FORWARD, TSMNEW, TSMRMV, STOP OFLBOOT, BOOTHOOK, CORCS, RECENT CHANGE, COMMIT, and END. Begin merely indicates the beginning of the software retrofit. Enter signifies the beginning of the tape loading stage. During the Tape stage, tapes are counted as they are read onto offline partitions of a file system. In the MOP stage, the offline partitions are mounted. In the Pump SM stage the new generic (software) is loaded into the offline side of the switching module. In the Pump CMP stage, the new generic is loaded into the offline side of the communications processor module. In the TSMOLD stage a list of out of service trunks is created and saved. In the Proceed stage the offline side of the administrative module is "pumped" or loaded. The OFLBOOT stage indicates the start of the boot of the administrative module. In the SWITCH FORWARD stage the switch changes from a side running the old generic to a side running the new generic. The TSMNEW stage determines mismatches against the out-of-service list from TSMOLD stage and a previous out-of-service list. The TSMRMV stage makes the out-of-service list of trunks match the list created at the TSMOLD stage. The STOP OFLBOOT stage stops offline boot and restores information on a side of the administrative module. The BOOTHOOK stage updates recent change information on the side running the new generic. In the CORCS stage customer originated recent changes are updated. In the RECENT CHANGE stage recent changes are reapplied. The COMMIT stage restores the switching modules so that both sides are on the new generic and hard drives on the administrative module are restored with the new generic. The END stage indicates the end of the retrofit. Of course, the stages of the retrofit are redefined periodically.

A message is associated with the entry into each stage and the exit from each stage of the retrofit. In some cases, a failure message is associated with a stage. Table 1 below lists exemplary entry, exit, and failure messages for the stages of a software upgrade in the preferred embodiment. In Table 1, the "Stage" column indicates the relevant stage of the retrofit. The "State" column indicates entry, exit (completion), or failure of the associated stage. For example, "Begin" (row 1) indicates entry into the Begin stage; "Begin Complete" (row 2) indicates exit from the Begin stage; and "OFLBOOT failed" (row 19) indicates that the OFLBOOT stage failed. The "Image" column indicates an action to be taken in the user interface in response to receipt of the message. In particular, "1" indicates that a designated area in the user interface associated with the stage should be colored yellow; "2" indicates that the designated area should be colored green; and "3" indicates that the designated area should be colored red. The "Recognition" column lists the message that relates to the state of the associated stage. For example, "REPT RETRO BEGIN RESUME WHEN SESSION HAS STARTED" (row 1) is transmitted in the ROP stream and detected in accordance with the present invention to indicate entry into the Begin stage of the retrofit. The "ProgressID" column includes a number that determines whether the associated stage is displayed in certain views of the user interface. More specifically, a number other than "0" indicates that the stage is displayed in the consolidated status view of the user interface; and "2" indicates that the stage is displayed differently, for example, in a predetermined color, in the user interface.
