Description

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a call forwarding system,

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a call transfer system and a method thereof, and more particularly, to a call transfer system and a method thereof, in which a sender (also referred to as a "sending terminal" And to transmit a call from a transmitting terminal only to a receiving terminal that satisfies a call connection condition (connection policy, condition or policy) specified by the user when attempting to transmit the call.

Call forwarding generally refers to the function of forwarding a requested call to another pre-registered place (for example, another receiving terminal, voice mailbox, etc.) when a call connection is requested from a transmitting terminal to a receiving terminal.

In recent years, there has been a need to expand and apply the above-mentioned concept (function) of call transfer as user services or user-specific communication services (hereinafter referred to as " user services ") increase. For example, based on the information collected by each sensor node (SN) of a sensor network (health state information of a user, weather information of a local area, etc.) In the case of providing a service, it is possible to presume a call forwarding method that allows information provided to a user to be truly needed and useful. To this end, (Sensor node) can be selected by the user, for example.

SUMMARY OF THE INVENTION The present invention has been made to solve the above-mentioned problems occurring in the prior art, and it is an object of the present invention to provide an apparatus and method for providing a user service to a user The present invention proposes a call forwarding system and a method for extending the concept of call forwarding of the call forwarding service.

In order to solve the above-mentioned problems,

A judgment unit for judging a presence or absence of a connection condition (connection policy) when there is a call connection request from the user (transmitting terminal) to the communication network; And a call transferring unit for transferring the requested call only to the receiving terminals meeting the connection condition among all the receiving terminals forming the communication network if the connection condition exists, The user can specify the connection condition by himself / herself, thereby solving the above problem.

In order to solve the above-described problems, the call admission control method

(a) if there is a call connection request from a user (transmitting terminal) to a communication network, determining whether a connection condition (connection policy) exists or not; And (b) if the connection condition is determined to exist, transferring the requested call only to the receiving terminals meeting the connection condition among all the receiving terminals forming the communication network, And the user can specify the connection condition by himself / herself when the call connection request is made, thereby solving the above-mentioned problem.

When the transmitting terminal makes a call connection request to the receiving terminal, the call connection request is made by designating the call connection condition by itself, and the call is delivered only to the receiving terminal satisfying the condition. Therefore, the effectiveness of the user (convenience, specialized) It is possible to provide the advantage of being able to plan. In addition, even in the case of a remaining receiving terminal whose connection condition is not satisfied, if the connection condition is satisfied after the connection request time, the call is automatically transferred to the remaining receiving terminal. Thus, the user can easily and instantaneously It also provides an advantage that can be utilized.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Reference will now be made in detail to embodiments of the present invention, examples of which are illustrated in the accompanying drawings, wherein like reference numerals refer to like elements throughout. It is to be noted that elements of other drawings can be cited when necessary in the description of the drawings. In the following description, a detailed description of known functions and configurations incorporated herein will be omitted when it may make the subject matter of the present invention rather unclear.

FIGs. 1A and 1B are views showing the construction of the system of the present invention, and FIG. 2 is a diagram showing the flow of the present invention.

The judging unit 11 judges whether or not there is a connection condition (connection policy) in a request for a call connection from a transmitting terminal (user) to a communication network (a plurality of receiving terminals) (s21) It is the part that performs.

The connection condition is a condition (policy) directly specified by the user (transmitting terminal) so that a call is set only in a receiving terminal that a user desires to make a call connection (setting) among a plurality of receiving terminals forming a communication network. Convenience, specialization) service can be provided. That is, the present invention enables the user to specify the connection condition such as the fact that the user can obtain only the information (user request information) substantially necessary from the sensor network, thereby enhancing the effectiveness of the user service.

The connection condition can be variously implemented according to the type of the user service, and an example thereof will be described in an application example of the present invention to be described later. In addition, the connection condition can be stored in the condition DB of the transmitting terminal, and can be updated (newly registered, deleted, changed, etc.) according to the situation.

Hereinafter, for convenience of explanation and understanding, it is assumed that a communication network is a sensor network and a receiving terminal is a sensor node. However, it should be apparent to those skilled in the art that the present invention can not be implemented only in a sensor network. Meanwhile, the transmitting terminal tries to establish a call connection to a communication network (sensor network) through a predetermined communication network, and the communication network can be implemented by existing communication networks such as GSM, W-CDMA, WiMAX and LTE.

The call forwarding part (12) carries out the function of transferring (s22) the call requested for connection from the user (transmitting terminal) only to the sensor nodes layering the connection condition specified by the user, Can be specifically made as follows.

If it is determined by the determination unit 11 that the connection condition exists, the query unit 121 queries all the sensor nodes of the sensor network that the user has requested access to (sensed) information (s221 ). All the sensor nodes transmit their own information to the information collection unit 122 in response to the query (s222). The information collecting unit 122 transmits the received (collected) information to the list generating unit 123, and the list generating unit 123 determines whether the collected (received) information satisfies the above connection condition, And generates a list of sensor nodes transmitting information rules satisfying the condition (s223). The call setup unit 124 sets the call requested by the user to the sensor node belonging to the list generated by the list generation unit 123 (s224), thereby setting the call connection request to the sensor node satisfying the connection request connection condition Delivery is realized.

On the other hand, even in case of the remaining sensor node that does not satisfy the connection condition, the connection condition may be satisfied after the time of the call connection request. In this case, the call transfer unit 12 can automatically transfer the call requested to connect to the remaining sensor node. This can be a particularly important function when the user is required to secure the desired information in real time. These automatic forwarding functions can be made optional by the user.

When a user requests (tries) a call connection, it can request a connection by specifying only a default command without designating a connection condition. The default command is also broadly included in the connection condition, but it is not a specific condition but, for example, information about what the user should basically have in the environment according to the environment in which the sensor network is built And an order to acquire. In the case where the environment where the sensor network is constructed is the hospital room, and the temperature of all the hospital rooms is always 20 degrees to 25 degrees, such as the presence of the patient, the user (hospital manager) You can specify the command 'Send current temperature'.

In this case, the determination unit 11 also determines whether there is a default command in the case of a call connection request from the user. If the determination unit 11 determines that there is no connection condition and only a default command exists The call forwarding unit 12 delivers the call requested to be connected to all the sensor nodes so that the default command can be performed by all the sensor nodes.

<Application example of the present invention>

For example, let's assume that the sensor network is a sensor network that provides the physician (user) with patient status in the hospital. The doctor (sending terminal) makes a call connection request to the sensor network that provides the patient status. When a call connection request is made, the transmitting terminal can specify the following connection conditions as an example.

Connection conditions: [body temperature over 38 degrees] <and> [in order of high body temperature] <and> [one patient]

The connection condition may be a single number or a plurality of connections as in this example. In the case of a plurality of connections, the conditions may be connected to each other by a predetermined logical operator such as 'and' or 'or'.

The determination unit 11 determines whether the above connection condition exists (s11). When it is determined by the determination unit 11 that the connection condition exists, the call transfer unit 12 transmits only the call request from the doctor to the sensor node satisfying the connection condition (in this example, it will be attached to each patient) (S12).

The query unit 121 queries a sensor node attached to each patient (S221), and the information collection unit 122 receives a response to the query from each sensor node and collects body temperature from each sensor node (s222). Based on the collected information, the list generating unit 123 generates a list of sensor nodes in the order of higher body temperature (s223), and the call setting unit 124 generates a list of the sensor nodes And sets the requested call from the doctor to the sensor node (patient) (s224).

On the other hand, if the patient who does not satisfy the above condition before the connection request time has the highest body temperature thereafter, the call transfer unit 12 automatically transfers the call requested for connection to the patient (sensor node). In addition, when the temperature management for all of the patients is required in real time, the physician can designate that "the body temperature of all patients will be notified in units of five minutes" as the default command, and there is a default command by the determination unit 11, If it is determined that there is no condition, the call forwarding unit 12 transmits a call request from the doctor to all the sensor nodes (all patients) so that the default command is performed by all the sensor nodes.

The method of the present invention can also be embodied as computer readable code on a computer readable recording medium. A computer-readable recording medium includes all kinds of recording apparatuses in which data that can be read by a computer system is stored. Examples of the computer-readable recording medium include a ROM, a RAM, a CD-ROM, a magnetic tape, a floppy disk, an optical data storage device, and the like, and also implemented in the form of a carrier wave (for example, transmission over a wired or wireless network) . The computer-readable recording medium may also be distributed over a networked computer system so that computer readable code can be stored and executed in a distributed manner.

The present invention has been described above with reference to preferred embodiments thereof. It will be understood by those skilled in the art that the present invention may be embodied in various other forms without departing from the spirit or essential characteristics thereof. The disclosed embodiments should, therefore, be considered in an illustrative rather than a restrictive sense. The scope of the present invention is indicated by the appended claims rather than by the foregoing description, and differences within the scope of equivalents thereof should be construed as being included in the present invention.
