Description

DETAILED DESCRIPTION OF THE INVENTION

BACKGROUND [0001] The present invention relates to a wireless communication system in which signals are transmitted via an air interface, and more specifically, to a device for supplying terminal-related information to a management system in the wireless communication system.

[0002] The cellular telephone industry has made tremendous progress in commercial activity in the United States and around the world. Growth in major urban areas has far exceeded expectations and system capacity has not kept pace. If this trend continues, the effects of rapid growth will quickly spread to even the smallest markets. Innovative solutions are needed to meet increasing capacity needs, maintain high quality of service, and avoid price increases.

Several trends are emerging in the design and implementation of wireless communication systems. For example, wireless communication systems were initially implemented primarily to support the demands of wireless voice communications, but wireless data communications have become a service that has been widely sought by subscribers. With the emergence of the Internet,
Wireless data services are becoming as popular as today's wireless voice services.

As part of the evolution of wireless communication systems, network operators continue to look for better ways to manage or optimize the operation of these systems. This requirement is emphasized by the management of wireless communication systems, which involves a large number of variables of a time-varying nature, such as when a subscriber moves around during a call or when a new building enters the city. Due to the fact that the load on system changes is very high. To address these needs, various tools have been envisioned to assist network operators in coordinating the operation of their networks.

[0005] Traditionally, network operators collect and process large amounts of performance data from the network side that are used to maintain and maintain the system by counter-based systems and other technologies. FIG. 1 is a diagram showing an example of such a conventional counter-based system. As shown in FIG. 1, the switching level / network level switch 105 has a number of event counters 0... N. For any one of these event counters 0 ... n, the network operator (human opera
tor) 115 must define the measurement program. This involves entering the appropriate commands into the switch 105 via the network operator's workstation 120, thereby counting the occurrence of a particular event within the time defined by the operator 115, with a corresponding counter. (
Or multiple counters). Then, the switch 105 increments the corresponding counter every time the event occurs.

The types of events that can be tracked using event counters 0... N include, for example,
Failure of handover to a specific cell (attempted), success of handover to one cell (successful), failure of handover from one cell to the next cell, or success of handover from one cell to the next cell included. At the end of the scheduled measurement time, switch 105 outputs the value stored in the corresponding counter to a post-processing application running on external workstation 120.
And the post-processing application, for the network operator 115,
Convert event information into user-friendly formats such as reports or graphs. The network operator 115 changes or updates the setting of the switch 105 based on the information provided by the post-processing application.

[0007] In some products of GSM, certain events are recorded and sent to an management system (OSS) for analysis. Here, the recording function is called mobile traffic recording (MTR; Mobile Traffic Recording) or cell traffic recording (CTR; Cell Traffic Recording). The MTR function can record different wireless messages sent during a call to certain subscribers. The CTR function can record different radio messages sent during each call, for example, the 100th call in a cell.

The above functions provide examples of operating parameters measured by the system, while at the same time certain measurements are taken by the mobile terminal and reported to the system. For example, in a digital cellular system, it is possible to perform signal strength measurements on the downlink, ie, transmissions from the base station to the user, to assist in performing a handoff. These measurements are generally mobile-assisted
This is referred to as a mobile-assisted handoff (MAHO) measurement and provides information to the system as to whether the channel is a good candidate for handover. In a system operating according to GSM, for example, MAHO measurements are transmitted over a Slow Associated Control Channel (SACCH). This S
ACCH is a dedicated physical (RF) established during a call between a mobile terminal and a base station.
One of many logical channels created from the channel. In GSM, for example, the SACCH occupies one of the 96 time slots associated with the traffic channel conceptually shown in FIG. 2A. In the figure, the physical channel occupies time slot # 1 in each frame of 8 time slots. In the case of the first 11 frames, the time slots are used for transmitting traffic information, and in the twelfth frame, the time slots are used for the SACCH. Systems designed according to other standards provide the transmission SACCH information along with traffic data or payload data in each time slot assigned to the mobile terminal's channel. For example, as shown in the time slot format of the uplink traffic channel in FIG. 2B in a system operating according to ANSI-136.

Another example in which a mobile terminal provides measurement information to the system operates as a measurement device for a system that uses mobile assisted channel allocation (MACA). MACA uses an idle mobile terminal (ie, a mobile terminal that is powered on but not currently connected to the system via a traffic channel) as a measurement probe to quantify local interference conditions. In the system. For example, an idle mobile terminal can be required to measure a traffic channel so that the system can determine which traffic channel to assign to another mobile terminal that needs to be assigned a traffic channel. These measurements are made by idle mobile terminals and are reported to the system via the broadcast control channel uplink.

[0010] Despite some of these examples where the mobile terminal provides the system with measurement reports on signal strength and / or quality measurements, current network operators require complete information about the mobile terminal's interaction with the network. Access
Inability to properly manage services and networks. Instead, the conventional MAHO and MACA techniques described above provide only limited information from the mobile terminals used by the system for traffic purposes. Information of all other mobile terminals that may be useful, for example, dropped calls caused by events (eg heavy local loads) that can possibly be compensated by the network operator, Information that assists the network operator in determining whether a call has been dropped due to an event that cannot be compensated (eg, when the battery is disconnected from the mobile phone) is not readily available to the network operator. Thus, it provides a mechanism for obtaining this type of mobile terminal information that can easily assist network operators for effective network management, and distributes network and service management functions to mobile terminals. It is desirable to provide a mechanism for doing so.

SUMMARY In the present invention, a management signaling channel is established between a mobile terminal and a management system for the exchange of management information, thereby establishing the above and other disadvantages and limitations of conventional network management techniques. And the problem is solved. The end points of this management signaling channel are in the mobile terminal and in the management system.

When a mobile terminal connects to a fixed part of the network, it may be used in a resource-efficient manner or in a manner that minimizes the impact from the user's point of view (eg, priority over user payload data). By transmitting a low-level management signaling channel), it is possible to transmit management information that can be obtained from the mobile terminal. When the wireless interface for transmission of the mobile terminal with respect to the management information is disabled (eg, when out of coverage, when the terminal is switched off, etc.), the mobile terminal management information for later transmission to the network Can be stored in the non-volatile memory. These technologies provide general service and network performance (
For example, provide the system with the ability to monitor failed services and failed calls (logged by the mobile terminal, but not registered by the system due to congestion or failure on the radio interface).

[0013] Similar management information can be logged on the system side of the air interface (eg, base station) and reported to the management processing node. On the management processing node,
By using this information, for example, by comparing the information received from the system side with the information received from the terminal side, the cause of the problem can be determined and corrective measures can be taken. M
The information available from the S-channel is also used for other purposes, not only to retrieve service performance, but also to provide the ability to configure services and networks based on what happened at the mobile terminal.

An MS channel according to the present invention is used by the network to query the mobile terminal for service characteristics such as, for example, what services are implemented and what their versions and status are (eg, active, passive, etc.). It also provides the enabling mechanism. Other characteristics of the mobile terminal may also be reported. For example, services that affect mobile terminal characteristics with respect to transmission capabilities, display characteristics (eg, what display characteristics are used so that they can be changed by plugging the mobile terminal into a computer using a PCMCIA card).

Another object of the present invention is to incorporate the ability to provide management information by customer base. This improves the network operator's ability to care for customers, which makes it more competitive in the market. Yet another object of the present invention incorporates the ability to correct a failure on the mobile terminal side of the system (eg, a problem with an outdated mobile terminal having an outdated version of service software) with an event occurring on the network side of the system. It is in. Yet another object of the present invention is to provide a mechanism for monitoring the actual QoS at a terminal for a system-defined quality of service (QoS). Thus, the present invention provides terminal and base station information used by the management system to improve the quality of service received by end users.

DETAILED DESCRIPTION The following description will disclose specific details, such as specific circuits, circuit components, techniques, etc., that provide a thorough understanding of the present invention. For illustrative purposes and not limitation. It will be apparent that other embodiments may be departed from these specific details. In addition, detailed descriptions of well-known methods, devices, circuits, and the like will be omitted so as not to obscure the description of the present invention.

An example of a wireless communication system described below is a time division multiple access (TDMA) protocol in which communication is performed between a base station and a mobile terminal by a number of time slots;
Alternatively, code division multiple access (CD) in which channelization is performed using different spreading codes
MA) shall be used. However, it will be appreciated by those skilled in the art that according to the concepts described below, other protocols may be used, including but not limited to frequency division multiple access (FDMA) or any combination of the above protocols. Will be easily recognized. In addition, although the embodiment according to the system based on GSM or ANSI-136 is illustrated, the technology described below is equally applicable to any type of system.

As described above, other information obtained from the mobile terminal (ie, information other than channel quality measurements) can be used to monitor network and service performance, correct faults, improve services, improve network configurations, It is desirable to use it for determining the behavior of the end user. For example, although the provision of a mobile service depends on the sufficient power supply that can be made to the mobile terminal, it is currently not possible for the operator to monitor the power supply status at the mobile terminal. In addition, in areas where there is a high demand for services, the management system cannot monitor the number of failed calls due to congestion. This information is very useful for the purpose of expanding the network to meet the increasing demand.

As shown in FIG. 3, in the embodiment, by generating a management signaling (MS) channel between a mobile terminal in a network and an entity (node) that provides network management information to an operator, Consider supplying this and other information to the system. As used herein, the abbreviation "MS" refers to "management signaling,"
Note that it does not refer to the commonly used "moble station". In the GSM example shown in FIG. 3, this entity is an Operations Support System (OSS) 300 and M
The S channel is conceptually indicated by a dashed line connecting the mobile terminal 310 and the OSS 300 and a dashed line connecting the computer 320 having a wireless modem (not shown) and the OSS 300. The OSS 300 is a node in a GSM-based system and is responsible for operation management and network management functions, subscriber management, and mobile device management. In addition to the MS channel of the present invention, the existing (conventional) interface is also shown in FIG. For example, zig-zag lines emanating from the mobile terminal 310 and the computer 320 indicate that these devices and the base station (base station subsystem (BSS; bas
5 shows an air interface with the e station subsystem) 330.
Furthermore, there are also interfaces between the BSS 330, the core network switching system 340, and the OSS 300, but these interfaces are well known and will not be described.

[0020] The MS channel can be implemented in many different ways. However, the remote terminal (
For example, a management system that collects information based on data received from the mobile terminal 310 or the computer 320 in FIG. 3 and a remote terminal (for example, FIG.
A dedicated channel (ie, point
A point-to-point (point-to-point) channel, rather than a two-multipoint (broadcast) channel, is preferred. The end point of the MS channel is called a node, in which the payload information is transmitted to the involved node (for example, BSS3).
30) is obtained in an uncoded form, as compared with the state of the information as it passed through 30). In contrast, the conventional SACCH terminates at BSS330. For example, in addition to conventional encoding processes performed at mobile terminal 310 (eg, conventional encoding, addition of cyclic redundancy check (CRC) bits, etc.), mobile terminal 310
In a manner as recognized by other end nodes (eg, OSS 300), the MS
It is also possible to encode information transmitted by the channel. For example, O
SS is Common Object Request Mediation Architecture (CORBA)
When connected to other parts of the system at the st Broker Architecture) interface 350, the mobile terminal 310 may also encode or format MS channel information according to the present description. As will be appreciated by those skilled in the art, as described herein, a management system (OSS) using CORBA is:
It is possible to incorporate a management function in the terminal relating to transfer and processing of management information from the terminal to the management system by the MS channel.

The management system may use any technology, architecture, or protocol (eg, Ethernet, wireless link, E1, T1, SDH, TCP / IP, SNMP) and other parts of the system. Can be connected to The same application protocol that the management system uses to communicate with the network components can be used between the management system and the mobile terminal. For example, assume that the management system communicates with different functions (nodes) that use different application protocols (which may be transmitted over IP or ATM, etc.). The protocol for Radio Network Controllers (RNCs) may be IIOP, or SNMP may be used for IP routers. Since the information from the MS channel is related to the information from the radio network controller, it may be necessary to use the same application protocol for the MS channel as for the interface between the management system and the RNC. It is advantageous.

In addition to coding or formatting different from other channels, which may be placed on the information to be transmitted by the MS channel, the channels according to these inventions are based on the way that they are allocated to the air interface throughput resources. , Conventional channels (eg, SACCH or traffic channels). For example, the MS channel “steals” another time slot (eg, a different time slot from the SACCH) from the traffic channel, as can be seen by comparing frame 14 of FIG. 2A and frame 14 of FIG. 4A. And can be realized. Alternatively, as can be seen by comparing FIG. 2B and FIG. 4B, it can also be realized by preparing a dedicated space for transmitting information of the MS channel in each time slot. Furthermore, the SACCH and the MS channel may be time-multiplexed. For example, SACCH information and MS channel information are alternately transmitted for each time slot. These are, of course,
Fig. 3 shows a simple example of different ways to allow the assignment of MS channels to throughput resources.

Furthermore, it will be apparent to those skilled in the art that the manner in which MS channels are allocated to resources can be varied depending on the type of connection technique used in the wireless communication system. For example, in a system in which the connection technique includes a CDMA configuration, as shown in FIG.
H) (including H).

FIG. 2 shows a part of direct sequence (DS) CDMA, in which a symbol stream to be transmitted (ie, a symbol stream on which channel coding, interleaving, and the like have been performed in block 400) is a signature sequence. A or spread code A, applied to a very high rate data stream. In general, signature sequence data (generally referred to as "chips") is a binary signal (binary) or quaternary signal (quaternary) and provides a chip sequence generated at a rate generally referred to as a "chip rate". . One way to generate this signature sequence is to use a pseudo-noi (PN) that is random but can be reproduced by an authorized receiver.
se) is to use a process. The symbol stream and the signature sequence stream can be combined by multiplying them by a multiplier 420. The combination of the signature sequence stream and the symbol stream is called symbol stream signal spreading. Each symbol stream or channel is generally assigned to a unique spreading code.

However, in the exemplary (base or mobile) transmitter of FIG. 4C,
The data stream to be processed is first split into two parts: MS channel information and other information (eg, traffic channel information, SACCH information, etc.)
This MS channel information is sent to a parallel branch that performs channel coding, interleaving, and the like in a processing unit 430 before being spread by a different spreading code B in a block 440. Before modulation and transmission, this information is added at block 450. On the receiver side, by correlating the combined signal with the two spreading codes A and B, the MS information can be identified from the traffic / SACCH information and extracted from the combined signal.

Hereinafter, an example of a technique for implementing the MS channel according to the present invention will be described.
As an example of implementing the MS channel, a method as shown in the flowchart of FIG. 5 can be considered as an overview. In the figure, in step 510, the mobile terminal 31
0 (or computer 320) logs and timestamps information that can be used in the system to know the movement of the mobile terminal in terms of system operation. For example, mobile terminal 310 can log events for a given terminal of interest to a network operator. For example, the power level of the terminal is below the threshold value, the terminal cannot connect to the system, the call is disconnected, the operating temperature of the terminal, the effective reception bit rate, the coverage, the interference level, the congestion, the transmission / reception signal strength, the number of message transmissions, Bit error rate (BER), C / I, Eb / IO for CDMA systems, calling procedures initiated on the radio interface interrupted by the end user, etc. Other examples of possible types of MS information (eg, for usage patterns associated with terminals) are described below, but it will be understood that they are not intended to be limited to the types of information listed below. When one of the predetermined events occurs at the mobile terminal 310, the mobile terminal 310 saves the identifier corresponding to the event in the memory together with the time information when the event was received.

In step 520, in parallel with the above processing in the mobile terminal 310, the BSS 33
0 performs log recording and time stamp of its own MS information. This MS information includes, for example, the following. Obstacles in receiving information from connected mobile terminals, system load (such as related to geographical area), terminal registration, transmission / reception signal strength, interference level, number of message retransmissions, BER, C / I, Eb / IO, etc. . If the transmitted / received signal strength from the base station and the transmitted / received signal strength from the mobile terminal are supplied, the management system can calculate the actual attenuation.

Then, in step 530, the OSS is transmitted from the mobile terminal 310 through the MS channel.
MS information (terminal ID or call identifier) is transmitted to 300. As mentioned above,
The mobile terminal 310 will add encoding or formatting to this information for compatibility with the OSS interface 350 and, since the MS channel is terminated at the mobile terminal 310 and the OSS 300, a separate air interface Can be used to separate the MS channel from other channels. BSS3
30 will also send the logged MS information (including the BSS ID or call identifier) to the OSS 300 without using the air interface portion of this channel. Then, in step 550, the management system operating in the OSS 300 processes the MS information received from both the mobile terminal and the BSS, and makes a predetermined determination based on these two pieces of information. With such a determination, the adjustment of the operation of the wireless communication system may be automatically performed, or the notification may be simply made to the network operator so that the network operator can selectively adjust the system operation parameters. You can also. Next, a more specific example will be considered.

By periodically recording the power level of the battery (for example, once every two times), a log of the power level of the mobile terminal 310 during a call is recorded. This time and power level information can be recorded in a memory (not shown) of mobile terminal 310. When the call between the mobile terminal 310 and the BSS 330 is disconnected abnormally, a log (other parameters of interest from the mobile terminal regarding the abnormally disconnected call can be included) is transferred to the OSS 300 via the MS channel, next,
The mobile terminal 310 transmits to the wireless communication system, for example, a call setup message (Call Setup).
Connect with a Location Registration message or a similar message.

The BSS 330 can record an abnormal disconnection of the connection between the mobile terminal 310 and the BSS 330 and perform a time stamp. At the same time, the BSS may provide any information that the network operator may want to focus on from a system perspective and that may be useful in determining the cause of the abnormal disconnection (e.g., congestion, location of mobile terminal 310, rapid bit rate requests for variable bit rate users). Increase) can also be logged. This information is also transferred to the OSS 300.

The OSS 300 uses the time stamp information together with the terminal ID and the BSS ID to compare information received from the mobile terminal 310 and the BSS 330 via the MS channel, and performs mutual association. Instead, both the mobile terminal and the BSS use a unique call ID (instead of or together with the terminal ID and the BSS ID) to provide more direct correlation of the MS information to the management system. You can also. In the above example, the OSS 300 may use the corresponding time stamped MS information received from the BSS 330 and the specific time MS information transmitted from the mobile terminal 310 (or a specific range of time stamped MS information). It is also possible to try to determine the cause of abnormal disconnection by evaluating. For example,
If, at the time of the abnormal disconnection, the mobile terminal 310 reports that the power level has fallen below the level required to maintain the connection, the OSS 300 classifies the problem as not due to system operation. And the data or reports generated for the scheduling of the system operation may not be included.

On the other hand, for example, the mobile terminal 310 reports that there is no problem in the log at the time of the abnormal disconnection (different from the disconnection of the terminal itself), and the BSS 330 has another CDMA at that time. If a sharp increase in the transmit power level of the transmission is recorded, the OSS 300 may determine that the bit error rate of the received uplink signal at the BSS 330 due to interference caused by other users is low enough to cause the call to be disconnected. It can be analyzed that it has increased. In this case, the OSS 300 can classify and report this problem or the like as indicating the desirability of performing the adaptation of the operating parameters of the network.

The present invention provides the network operator with the possibility of obtaining information from the mobile terminal's point of view, how the radio access network operates, and in particular the various services provided by the network It will be appreciated that this will allow one to determine how is operating. There are many other applications for the wireless communication system employing the MS channel according to the present invention. Hereinafter, some of them will be described.

For example, the present invention will have the ability to remotely control (from a management system) a service at a mobile terminal. For example, by adjusting the service data (ie, what information should be monitored and logged, and how much past log data can be discarded at the mobile terminal when not connected to the network) You can cut off services that do not fit. An example of an incompatible service that can be turned off is a service whose software has been upgraded (eg, a video conferencing service), and the software is still available on the terminal (although the service provider recommended the user of the terminal to upgrade). May not be compatible because an older version of is installed. Such a service may be disabled using the MS channel to clarify the mobile terminal (eg, that older versions of video coding are no longer supported for video conferencing services).

The present invention also has the ability to remotely load software (eg, service logic or patches, as well as testing of service logic) on the mobile terminal. This type of software upgrade or software test can be delivered and controlled, for example, via the downlink of the MS channel.

Further, the present invention has the ability to remotely monitor service and network performance at the mobile terminal. This provides the network operator with the best opportunity to measure the quality received by the customer. Examples of services and network performance related to parameters and events to monitor at mobile terminal 310 include, for example: That is, the interaction / behavior in the user's network, the selection and access of specific services (eg, SMS services, video services, call forwarding, conference calls, channel throughput selection, etc.), and the radio interface to access the services. Whether to block or otherwise interfere with the performance of the service (from the mobile device's point of view)
Radio interface performance, judgment when a call fails due to congestion in the radio interface, etc.

The present invention may also be used to evaluate methods of various services interacting at the mobile terminal and / or to stop other active services invoked by the mobile terminal. It also provides tools that can be used. Such a situation may require, for example, reducing the bandwidth or stopping the service for one or several services if the cumulative bandwidth required for all active services exceeds the bandwidth allowed on the radio interface. It will happen in some cases. Examples of such situations include, for example, video conferencing communications (
End-users will need real-time MPEG
2 (using a bandwidth of 2 Mbit / s). If the wireless communication system only supports connections of eg up to 2 Mbit / s, the terminal can log this event to the management system for reporting. This type of information can be useful to network operators, for example, for planning purposes.

With the MS channel according to the invention, other types of terminal events can be recorded and forwarded to the management system. Such events include, for example: That is, the battery was removed without turning off the mobile terminal, the battery was removed during a call, an interruption occurred during a signaling procedure, the mobile terminal was tampered, and the like. If the battery power level is high, the BER is low, and the signal strength is high when the call disconnection occurs, the management system can conclude that the battery has been removed. The detection of an event related to hardware tampering in a mobile terminal can be performed by attaching a microswitch to a bolt of a terminal case and detecting that the terminal case has been removed.

The present invention is not limited to a particular embodiment. The above-described embodiments have been disclosed for purposes of illustration, and many alternative embodiments may be contemplated.
All such modifications are included in the scope and spirit of the invention as defined by the appended claims.
