How to use a landline phone number for a wireless user of a comprehensive wired-wireless system

The present invention relates to a wireless communication system, and more particularly, to a method of using or reusing a telephone number generally assigned to a wired portion of a communication network for a wireless user.

In the past, most households had only one telephone line. In addition, operators had only one telephone line for several employees, or at most one assigned telephone line per employee.

However, as the population grew and the economic trend moved into the information age, the demand for additional directory numbers increased. It is now common to have multiple telephone numbers for one or more telephone lines, facsimile devices, Internet access and wireless communication devices in the home. Business needs also doubled. As a result, local service providers literally ran out of telephone numbers. Area code rearrangements and extensions are currently used to generate more phone numbers, but such extensions cannot continue. Moreover, because of the rise in telephone number demand, telephone numbers have become very valuable goods for service providers, operators and households pursuing these assets with corresponding price increases.

Recent efforts to extend wireless communications and to better introduce the features and performance of wires into wireless communications have led to dramatic changes in the network architecture. An example of this is the invention named "Integrated Wireline and Wireless System (IWWS)" and was proposed in the US application (Application No. 08 / 942,895) filed October 2,1997.

The proposed IWWS does not require a mobile switching center (MSC), and effectively uses existing wired switching equipment and functions to provide a comprehensive wired-wireless service to wireless users. The final combination of wireless communication system elements and wired network elements provides service providers with many commercial and technical advantages. For example, the IWWS architecture allows service providers to reduce network equipment purchase costs, lower maintenance costs and simplify equipment integration. In fact, wired and wireless service providers have the option to use existing wired functionality without relying on separately prepared MSCs to provide low-cost wireless services.

By eliminating MSCs, service providers can not only reduce hardware costs, but also easily integrate wired and wireless coupling requirements, and easily incorporate many of the features currently offered in wired services into wireless services. And centralize physical operations and maintenance centers.

The present invention takes advantage of the extended functionality of the proposed IWWS by providing a method of using a common telephone number set for wired and wireless users. Wireless architectures based on MSC require a distinct and unique set of telephone numbers. As a result, the lack of telephone numbers in the landline or wireless sections requires the allocation of additional telephone numbers.

Since the proposed IWWS does not require an MSC, the present invention realizes that local service providers and other operators "integrate" phone numbers assigned to them into a single resource or database. The term "database" is subsequently used to broadly describe any and all indexing media, memories, in a method of storing, maintaining and interpreting telephone numbers.

Therefore, the present invention provides a method for connecting a calling party and a receiving party in a communication system having a comprehensive wired-wireless sector provided with a common telephone number database comprising telephone numbers for wireline users and telephone numbers for wireless users. to provide. In addition, the call connection to the wired or wireless user in the communication system is transparent to the calling party. In other words, regardless of the nature of the receiver, the incoming call from the originator is connected to the receiver with reference to the common telephone number database.

More specifically, the method of the present invention connects a call from a calling party to a receiving party in a communication system having a comprehensive wired-wireless sector. The method comprises the steps of providing a database having a telephone number for a wired user and a wireless user, receiving a call at the wired unit and detecting whether the telephone number for the receiving party corresponds to the wireless user telephone number with reference to the database. AIN, when detecting that the telephone number for the receiving party corresponds to a wireless telephone number, sends a wireless user location message through a mobile management interface such as an improved IS-41 or IS-634 link. Delivering from the SCP to the radio and completing a call setup between the switch and the radio at the wireline via a GR-303 link.

The database also includes global title translation information, routing tables, and digit translation information commonly found in communication networks carrying calls. The method also actively supports a single coupling function for wired and wireless users.

1 is a block diagram of an exemplary IWWS architecture that is well adapted to the method of the present invention.

Hereinafter, the present invention will be described in detail with reference to the accompanying drawings. In FIG. 1, the wired portion 100 generally comprises an AIN SCP 102 connected to the exchange 101 via an exchange 101 and an Advanced Intelligent Network (AIN) link. The exchange 101 is typically part of a Public Switch Telephone Network (PSTN) 105, but is shown separately here for the sake of clarity.

The wireless unit 200 is connected to a Visited Service Control Point (VSCP) 202 through an SS7 link, and is connected to a plurality of base station transceivers (Base Station Transceivers: hereinafter referred to as BSTs) 205. It is configured to include a controller (Base Station Controller: BSC) 201. Each of these components and interfaces is described in detail in the above-mentioned application.

The exchange 101 is connected to the BSC 201 through the GR-303 interface. The AIN SCP communicates with the VSCP202 through a mobility management interface such as an improved IS-41 or IS-634.

A telephone number database common to wired and wireless users is preferably present in the wired section and may be combined with the global title interpretation information, routing table and digit interpretation information already present in the communication network to facilitate call delivery. .

For example, when an incoming call from the PSTN 105 is received at the switch 101, a receiving telephone number is compared with the telephone number database, and if the receiving side is a wireless user, a wireless user location message is moved. The general process of sending the AIN SCP 102 from the AIN SCP 102 to the VSCP 202 via the management interface and connecting the calling party to the receiving party, i. On the other hand, when the receiver's telephone number corresponds to a wired user of a communication network, a wired call connection process is normally performed.

Here, a very important point is that the incoming call accesses the same telephone number database regardless of its nature, whether the receiver is wired or wireless. Therefore, separate telephone number sets do not have to be maintained. The telephone numbers in the database can be reused at any time by the service provider regardless of whether the telephone numbers were previously used by wired or wireless users.

The above-described embodiments are merely examples of implementing the present invention. The invention is disclosed by the embodiments described above, but is not limited to the embodiments. Rather, one of ordinary skill in the art would understand many improvements and alternatives applied to particular components that make up a network architecture that can be adapted to the present invention without departing from the scope of the following claims, which define the invention. There will be.
