Definitions
- This invention relates to simulation tools, and more particularly to a tool for simulating a wireless environment for a multiuser subscriber communication system.
- Wireless communication devices are becoming increasingly commonplace. For example, millions (if not billions) of individuals own and/or utilize one or more WCDs such as, but not limited to, a mobile phone, personal data assistant (PDA), a wireless gaming device and a computer with wireless capabilities.
- WCDs Wireless communication devices
- PDA personal data assistant
- service providers A user subscribes with one of these service providers to receive service.
- Each carrier forms a network that provides wireless service to its subscribers in various geographical areas of the world. For example, one service provider may provide service covering the East Coast region of the United States while another may provide service covering various portions across the United States.
- two or more service providers hereinafter roaming partners
- a WCD in a roaming mode scans for and selects a network to provide service to the WCD.
- each service provider has a roaming list that assists a WCD in acquiring service.
- the roaming list is an indexed list of systems or networks that is stored in each WCD and may be proprietary. Additionally, a set of data structures and algorithms, for service selection identifies the best network suitable for a given WCD to operate in a given environment.
- the roaming list can be any listing compatible with the communication standard used by the WCD.
- roaming lists are a public land mobile network list (PLMN list) and a Preferred Roaming List (PRL).
- the set of data structures and algorithms may be called system determination (SD) and can be used in combination with the roaming list to provide the identification of the best network suitable for the operation of a given WCD. While the terminology "PRL” and “system determination” are used herein, it is understood that the concepts are applicable to a variety of standards and technologies used in connection with wireless networks and wireless subscriber networks.
- TDS Technical Data Sheet
- HLR Home Location Resource
- SIDs channel information
- contact information information such as, but not limited to, the Home Location Resource (HLR), switches, SIDs, channel information and contact information.
- the TDS is used to help create the PRL, but is not standardized and exists in different formats.
- the system determination procedure uses the PRL in the WCD to select a system that will provide service to the WCD. This selection process is not standardized. Also, the system determination is dependent on the OEM's implementation and may be proprietary. Accordingly, service providers may have no specific insight on how a particular system was selected. Therefore, it can be difficult for service providers to troubleshoot PRL problems. On the other hand, due to the proprietary nature of PRLs, it may be difficult for OEM to help troubleshoot the PRL problem. For example, a representative of OEM can manually examine the PRL and step through it's contents, while making assumptions on how the PRL is being executed in the service provider's environment. Therefore, there is a need to provide information that is useful to the service providers without compromising the proprietary information.

- Fig. 1 is a diagram depicting an example wireless environment in a local geographical area.
- a plurality of base stations 110, 111, 112, 113, 114, 115, 116, 117, 118, 121, 122 are depicted at different physical locations.
- a wireless communication device (WCD) shown at 131, 132, 133, 134 is able to communicate through the base stations 110-122 if the WCD is within a suitable signal range of one or more of the base stations 110-122.
- the base stations 110-122 may be a part of a primary carrier's system in a local market, or may belong to those of another carrier.
- base stations 110- 122 are used by multiple carriers, and in some cases multiple carriers co-locate their base stations, as depicted at 113A, 113B, 113C and at 116A and 116B.
- the base stations may be assigned to different geographic markets of the different carriers.
- the different base stations may offer different types of communication service, such as CDMA, WCDMA, OFDM, GSM-based communication systems or AMPS service.
- the WCD may select the various base stations in accordance with a service determination procedure.
- the service determination procedure is implemented by a preferred roaming list (PRL).
- the PRL includes a system table and an acquisition table.
- the system table contains records identifying a system, for example by its System Identification number (SDD) and Network Identification number (NID). For each record, there is an indicator indicating a class of preference of the system, such as numerical, positive or negative.
- SDD System Identification number
- NID Network Identification number
- the system table also contains the roaming status that should be indicated by the WCD, the relative priority of the system and its geographic region.
- the acquisition table provides the band and frequencies that the WCD is to use when attempting to acquire the system.
- the approach is intended to provide the WCD with instructions to communicate with the base stations 110-122 according to roaming preferences set by the carrier. Ideally, the WCD should communicate with its home network in preference to roaming, and should roam according to preferences established by the PRL.
- the WCD is at position 131, then the nearest stations are 110- 114. These may be on the same or different networks, or multiple networks may be co- located, as depicted at 113 A, 113B, 113C.
- the WCD may move, for example to positions 132, 133 and 134, in which case the WCD establishes communication links with different ones of the base stations 110-118.
- the WCD being at location 132
- the best connection is through base station 122, located across an international border 145. While the user may rightfully presume that location 132 is on one side of the border, it may be that the only available communication link effects roaming across the international border 145 by establishing a link with a base station 122. This roaming option may be valid for users who place calls from across the border, but can be unexpected when the user is on one side of the border establishing a wireless link on the other side.
- International border 145 is an extreme example of a border as applied to wireless technology.
- non-political borders of regions related to the various system operations of wireless service providers are variously referred to by different terms, such as service areas, service territories, local areas and markets, and may be as arbitrary as political borders.
- borders generally are more often those related to territories established by service providers.
- Fig. 2 is an example block diagram showing a simulation device 200 that may be used in monitoring the operation of a WCD during system acquisition.
- Device 200 may be a desktop computer, a laptop computer or various other devices having processing capabilities.
- Device 200 comprises a memory store 210 configured to store a monitoring program; a processing module 220 configured to perform a system determination procedure based on a preferred roaming list and the monitoring program, and an output module 230 configured to output the results of the system determination.
- Memory store 210 may take various forms, typically in the form of computer memory.
- the system determination procedure may include various processes and/or may generate various results.
- the system determination may be implemented to perform one or a combination of a pilot scanning, a system acquisition, a system selection, or other processes associated with the system determination. Accordingly, output module 230 may output the results of the pilot scanning, the system acquisition, the system selection, other processes, or a combination thereof.
- the monitoring program may be an executable program file and memory store 210 may store the SD algorithm or codes as library files, such that the SD codes are not revealed.
- the monitoring program interfaces is then executable by processing module 220 using the library files.
- the monitoring program and the library files may be downloaded through a network or may be transferred through another storage medium.
- processing module 220 may be configured to emulate the system determination based on a technical data sheet (TDS).
- TDS technical data sheet
- Device 200 may further comprise a TDS input unit 240 configured to receive the appropriate TDS for use by processing module 220.
- the simulation is an actual system determination such as that performed by a WCD. Therefore, if actual signals are used, the simulation will be an actual system determination using live signals. This simulation may also be performed with a signal emulator, in which case the simulation is an actual system determination as performed with the emulated signals.
- Processing module 220 may emulate the system determination during various conditions and/or functions. For example, the system determination may be performed when a WCD is powered up, when a system is reacquired after the system is lost or when a WCD is powered down.
- Other conditions may be emulated such as, but not limited to, bad overhead messages, border interference scenarios, and complex signal interference situations. It should be apparent to those skilled in the art that there are many different conditions and/or functions that can be emulated in order to monitor and/or analyze the system determination performance. Some effects can be characterized in a manner that provides a convenient means for describing the effect. For example border scenarios can be described as "add bleed", which indicates to the user that transmissions are bleeding over into the wireless environment in the simulation.
- Device 200 may also comprise a user interface configured to receive commands to perform the various processes and/or functions associated with a system determination.
- the user interface may be implemented to receive commands such as to, but not limited to, initiate a pilot scanning, stop a pilot scanning, save a current result of a pilot scanning, open a stored result of a pilot scanning, emulate a WCD power up, emulate a system loss, emulate reacquisition of a system, and emulate a WCD power down.
- Output module 230 may include a display module configured to display the results of system determination.
- Fig. 3 is a representation showing an example of a display 300 that may be displayed by a display module.
- Display 300 displays information such as a scanning progress, a serving system, location, a scan list and an alternate scan list. As depicted, the display is indicating various geographical designations.
- Display 300 may further include a user interface.
- the user interface may comprise input interface to initiate a pilot scanning, stop a pilot scanning, save a current result of a pilot scanning, open a stored result of a pilot scanning.
- display 300 shows a display of certain information, it should be apparent to those skilled in the art that other information can be displayed as needed.
- display 300 shows a user interface with a certain input interface, it should be apparent to those skilled in the art that other input interface to perform various processes may be implemented.
- the display 300 may be operated on a general purpose operating system such as Microsoft Windows or Unix environment. Other applications and/or environments can be implemented.
- the display includes relevant data such as market name, channel information, geographical information, information concerning the system operator, and data related to the source of information.
- the particular information displayed is a matter of design choice, for example providing a display of "Voice Information” and "Data Information” as shown. Additionally, a parallel set of information can be provided.
- the first set of displayed data is indicated as “Voice Information” and the second set of displayed data is indicated as “Data Information”; however it is possible to provide different displays.
- the display of the information and/or user interface may be re-arranged and/or modified in various ways to provide a different "look and feel.”
- the content and display format of the information may be re-arranged and/or modified, and information can be added or deleted.
- the content of scan list may have more or less than the number "No.”, "Mode,” Band Class “B and C”, “channel” and “SID.” It can have a display format that displays the list from high number to low number.
- the location information may list the user's location in other forms such as, but not limited to, latitude and/or longitude, a particular market location, a city, a county, a district and state.
- This window contains the current RF information about existing systems and channels of operation. This information is obtained from a carrier's TDS, and shows the current preferred roaming list (PRL) data loaded into the software. In a typical emulation, this information is used to scan available channels.
- PRL preferred roaming list
- the display can include multiple windows, such as the separate "Voice Information” and "Data Information” depicted.
- the particular depiction shows the "Data Information” as having different fields than displayed for the "Voice Information”.
- Other options may include “Change Location”, “Bleed Systems” and “Manual Input” selections, depicted as radio button selections on the display.
- the “Change Location” selection allows the user to change the location to a different location either within a local area as depicted in Fig. 1, or over a large geographical area.
- the “Bleed Systems” selection permits “bleed” from neighboring markets or systems to be introduced into the simulation. This allows the simulation to incorporate interaction of wireless services across regions.
- the “Manual Input” selection permits the user to input details manually, either to test the effect of an additional variable into the wireless environment or to incorporate data not included in the databases stored in device 200. The user interface for these options will be described in connection with Figs. 7-9.
- device 200 is a simplified example for the purposes of explanation. Therefore, device 200 may comprise other elements and/or functions. For example, it may comprise an input module coupled to processing module 220 and configured to receive the preferred roaming list for use by processing module 220. Also, one or more of the various elements of device 200 can be rearranged and/or combined without affecting the operation of the system determination in order to monitor and/or analyze the various processes.
- the processing module 220 may be configured to perform system determination in a manner which does not permit the user to decode the system determination algorithms or software. If the system determination algorithms are not disclosed to the user, the system determination function is a black box function. Therefore, since what the system determination does is in effect treated as a black box, modifications and/or changes to the code in order to maintain secrecy of the code are significantly eliminated, thereby reducing the cost and overall efficiency.
- the system determination is performed in the manner performed by a WCD.
- the processing module performs the same system determination as performed by a WCD.
- device 200 selects a user-location subset of records from the TDS file and if a band class, channel pair to be scanned occurs in the selected subset, a system is deemed to be found.
- device 200 may be implemented to connect live with a base station in order to detect or receive some form of actual RF for a band class and channel to be scanned.
- Fig. 4 is a flow chart showing an example method 400 corresponding to the operation performed by device 200.
- Method 400 comprises loading (step 410) a monitoring program, loading (step 420) a preferred roaming list, performing (step 430) a system determination procedure based on the preferred roaming list and the monitoring program, and outputting (step 440) the results of the system determination.
- the performing the system determination may comprise performing a pilot scanning, a system acquisition and/or a system selection.
- Outputting the results may comprise outputting the results of the pilot scanning, the system acquisition and/or system selection.
- the method may comprise receiving a command to initiate a pilot scanning, receiving a command to stop a pilot scanning, receiving a command to save a current result of a pilot scanning, receiving a command to open a stored result of a pilot scanning, and/or receiving a technical data sheet; and wherein performing the pilot scanning comprises emulating the pilot scanning based on a technical data sheet.
- Emulating the pilot scanning may comprise emulating the pilot scanning when a WCD is power up and/or when a system is reacquired after the system is lost.
- the method may further comprise receiving a command to emulate a WCD power up, emulate a system loss, emulate reacquisition of a system and/or emulate a WCD power down.
- Outputting the results may comprise displaying either one or a combination of a scanning progress, a serving system, location, a scan list and an alternate scan list.
- Fig. 5 is a flowchart showing an example of a simplified system determination operation 500 in an emulation mode that can be implemented by device 200.
- the PRL and TDS files are loaded (step 510). Once the files are loaded, the internal data structure is set up in device 200. Thereafter, the scan list is accessed (step 515) from the SD code. Once a location is provided (step 520), the SD operation is ready to be performed (step 525). If in a powered up mode (step 530), the SD code is accessed (step 535) for the band class and channel information. The RF environment is emulated (step 540) and the TDS is accessed (step 545) for location. When a channel is found (step 550), the process stops if the channel found (step 555) is a preferred channel. Otherwise, channel searching continues (step 560).
- the system can load an alternate version of a PRL and perform the system determination 500 using the alternate PRL. This permits the operator to perform simulations of different PRLs in comparison. Similarly, comparative simulations can be performed with alternate TDS versions.
- the simulation can be performed according to different capabilities assigned to the WCD.
- a simulated WCD can be assigned different communication service capabilities, which, for example, could indicate the effects of the service on roaming.
- the software In a "phone" mode, the software will perform an emulation to behave as a WCD automatically, and will try to acquire systems in a scanning operation, accept handoffs and attempt to re-acquire a communication link when the connection to the system is lost.
