The presence status of the communication partner in the primary network is examined automatically with the help of the primary destination address before a connection establishment with a communication partner. If the communication partner is not present in the primary network, a connection over the secondary network is organized with the help of the secondary destination address. The connection to primary network is constructed by Wireless local area network or Bluetooth Bluetooth(RTM: Bluetooth is a short range wireless connectivity standard). The mobile phone is connected with the primary network by a residential gateway which makes the coder decoder computations for the Voice over internet protocol network. The residential gateway is a session initiation protocol client. An independent claim is also included for residential gateway.

Description

The The present invention relates to mobile phones, and more particularly to Method and device for establishing a communication connection between a mobile phone and a subscriber over different Networks.

Overview of the Invention:

phone calls become common from the mobile phone manufactured by GSM, CDMA UMTS, PCS or comparable radio network standards.

in the The following is because of the universal characteristics of these different Standards of corresponding network operator radio systems only spoken by GSM. Close telephone connections In this context, data connections are generally included.

State of the art:

mobile phone calls via GSM technology by a network operator against the user Allows payment, Flat rate (flatrate) or billed per unit of time.

The Use of alternative (non-GSM) connection ways to manufacture from voice or data connections to far-flung participants or server-based voice or data services is in conventional Mobile phones not provided. Exceptions here are at most gateway Telephony as applied to calling cards or callback services. Nevertheless, starting here, too, the GSM network is mandatory used as a cable route.

For inexpensive Telephoning it is known by dialing special area codes calls via telephone service providers redirect who offer phone calls at cheaper rates, as a fixed or mobile network operator. In addition, are for wired Telephones or landline connections Facilities known that allow telephone connections automatically over the cheapest Make telephone service providers. This is after an investigation of for the chosen one Cheapest phone number Telephone service provider by setting up the telephone number dialed by the user automatically precedes the corresponding area code and the Conversation about the Telephone service provider redirected or mediated.

There Mobile phones are involved in mobile networks, would have a to the wired network analogue device for automatic Preselection of area codes have a sender and a receiver, with the received by the mobile radio signal received, the elected Number with a prefix number and back to the base station is sent out. Such a device would be very complicated and cumbersome to use.

When possibility for communication at reduced rates in fixed networks and mobile networks, for example abroad, so-called calling cards are also known with the help of which a user by dialing a prefix and then the desired Can call a subscriber number.

at Calling Cards will lead to that conversation indirectly via mediates an exchange of a telephone service provider, where the phone call is charged, taking the call first through Choose So-called toll-free numbers of the exchange of the provider the calling cards over the exchange is running.

Such Toll-Free numbers are for the caller for free, regardless of which telephone network he is calling from. The cost of the conversation will be from the network operator or mobile operator of the user the telephone service provider this Toll-free number and not charged to the caller.

Of the Therefore, customer only calls the special toll-free number of the service provider which causes him no direct costs, whereupon he subsequently the destination number of the desired caller chooses and through the calling card provider is connected. The cost of that indeed desired conversation are then calculated by the calling card provider and by a the user assigned credit account, which the customer in the Usually has to fill up first, debited.

From the DE 103 05 621 A1 is a method for the use of pre-paid and / or calling card services for mobile phones with SIM cards known in which a credit is given specifying a mobile phone number, then a message is generated with at least one command for programming the SIM card in which this message contains at least information about the ordered balance and a telephone number that must be dialed to unlock the credit, then the message is sent to the specified mobile phone number, the message is stored on the SIM card and read out, finally the SIM card is programmed according to the at least one command of the message by a programming device and the credit is automatically unlocked.

According to another aspect of the of DE 103 05 621 A1 known method, the generated message and the programming device can be set up so that on the SIM card or similar storage device contained phone book entries are automatically revised so that a "remember" or "recording" of stored numbers is no longer necessary.

Alles these approaches is common that the phone is common only over the GSM network can establish voice and data connections.

A Exception is at most the so far implemented by a few manufacturers Possibility, Using Bluetooth within a room or building to call directly from terminal to terminal or transmit data. long-distance calls or connections to more distant mobile or other telephone users are about not to make such a local connection.

Overview of the Invention:

task the present invention is to provide a method in which a mobile telephone or mobile terminal due to determinable Automatically make a phone call via identifiable paths or builds alternative networks.

Is solved This object is achieved by the present invention, whose features the independent one claims can be seen. Advantageous developments are the present Invention describes a scenario in which mobile phones are present of different conditions independent of the GSM network operator automated via alternative, Connection paths such as voice over IP or landline are led - with appropriate Advantages for the user in terms of voice quality, availability, transfer volume and can also be the cost. It chooses the user the known telephone number of the desired User, the system automatically finds the most advantageous for the phone call Line Path / Provider and automates the connection for the user ago.

For this, another physical transmission medium must be made available, as it were, past the GSM network operator:
In order to use GSM for telephone calls other than the hitherto usual medium, WLAN and Bluetooth would come into question - as in standard mobile telephones built in radio standards - whereby the gateway around the radiotelephone call forward is at the disposal of the user, as well as in range must be. This can be a public hotspot or a so-called residential gateway, ie usually a broadband WLAN router.

In order to transmit the (voice) data to the desired subscriber can be have to according to a VoIP standard, e.g. SIP or H.323 be coded. As usual Mobile phones for this however, as to Computing power is not always designed, lends itself to the processing of (Telephony user) data, that is the compression, encryption, Encapsulation and shipping of data within the residential gateways themselves, and the handset only for audio transmission as well as the keyboard and election related functions such as call of the telephone book or ringing on incoming (VoIP) call to use. This Approach is only one way.

It but also the generation of the codec (ie the VoIP packets) in the telephone itself, if this is sufficiently powerful.

Of the The advantage here is that in the presence of a corresponding Gateways with conventional Mobile phones IP telephony becomes possible.

On The side of the mobile phone is to proceed as follows: To concretely the Bluetooth standard for transmission user data (digitized language, data and / or dialing information) to use on a residential gateway was from the bluetooth SIG a Bluetooth profile called CTP, Cordless Telephony Profile released, in which a connection from a Bluetooth-enabled mobile phone to a non-GSM phone system is enabled.

in the The case of the invention is preferably not the CTP for this, but The Bluetooth Handsfree Profile HFP is related, with the Handsfree Client resides on the mobile phone. Simulated in this approach thus the mobile phone the headset itself. Usually that is Mobile phone is the source of voice information and redirects it any Bluetooth headset that is pairing (connection) with the mobile phone.

there the user uses the mobile phone in addition to GSM network on a residential gateway, as soon as he within reach. The advantage is that he is essential Functions of his GSM mobile phone, here in particular the usual ones Phonebook memory also for the alternative, cheaper Can continue to use the connection path.

For the connection of the handset to the Internet, a gateway (Residential Gateway (RG)) is being developed, which can be connected to the handset via Bluetooth connects (HFP) and connects as a WLAN client or via a LAN port to the Internet router.

Of Further in the RG the speech coding / compression, as well as the VoIP Signaling realized to the processor of the handset as much as possible to relieve.

The Configuration of the RG is done by means of a menu item in the handset. The configuration data (WLAN parameters, SIP parameters, etc.) are transmitted via Bluetooth serial transmission transmitted to the RG.

has the gateway in addition the function of a VoIP converter, so there is the possibility of paid To avoid phone calls by previously automated at a corresponding Service (e.g., SIP Registrar) requested by the residential gateway is, if the person to be called if necessary over IP cheaper as over a GSM call would be reached, or whether the voice quality over IP sufficient is big. Also can be decided an IP data connection over this Gateway to build. The SIP standard makes it possible to use a location and a presence server, the whereabouts, and the reachability status of a user. This creates the possibility the user priority over VoIP connect to. Is the opposite currently not registered in the SIP network, then automatically the next- more expensive connection chosen, So GSM or a calling card gateway, the user if necessary via a Display message about this informed.

Conceivable is one constantly Updated status display of all phonebook contacts by the presence server of the handset, which already before the telephone call the fundamental Availability of a possible interlocutor displays.

About the System can also be transmitted data messages, in particular SMS and MMS.

costs for short messages can be avoided by using alternative network paths (IP flatrate) if both users are logged in the system.

is Only the sender logged in the system, so the outgoing message can be over alternative SMS gateway cost-effective to the (currently obvious mobile) receiver be shipped.

The IP connection via the RG lets also for the cost Browsing the internet via Use the HTML or WAP browser of the handset, as well as others Peer to peer services such as video conference or file sharing.

Overview of the characters

Detailed description of the preferred Embodiments:

The 1 shows the state of the art, in which a computer or a telephone is connected via a DSL connection with a SIP server. This SIP server is also called Registrar. It serves as a kind of switching centers and recognizes the sender and the recipient of the call on the basis of the transmitted identifiers. He can take over the signaling and the switching of the call. In the preferred embodiment, it serves as an exchange for name / telephone numbers and IP addresses. The actual data flow takes place after switching over the Internet without further connection to the SIP server. The SIP server also has the function of managing the presence status of each participant.

The 2 shows an alternative environment of a network in which the phone is connected via a telephone system or a telephone network to the Internet, the mobile phone over a Bluetooth access point, the laptop via a WLAN access point and the computer via a HUB or a network switch. All elements communicate through a DSL router or other network router that connects the local network to the Internet. It should be noted that, of course, a direct connection to the Internet can be given without a DSL router.

The 1 shows a further alternative embodiment in which the Bluetooth access points is designed as a bridge. In this case, the connection to the mobile phone is realized via Bluetooth, and then connected to a WLAN access point via WLAN. This approach has the advantage that fewer cables are needed to build a network. The connection can thus be managed via a central point. The WLAN allows higher data rates and distances, so that multiple mobile phones can be connected to the Bluetooth bridge to then forward data over the WLAN or the protocol.

The 4 shows a further embodiment of the Bluetooth access point. This is either directly connected to a HUB or switch or goes via a WLAN Bridgemodul. This Bridgemodul establishes a wired connection to the Bluetooth Access Point and then wirelessly connects to the WLAN access points and thus to the Internet via WLAN.

The 5 in turn represents an approach for the routing of individual calls in the phone book of the mobile phone are under the name "Other Party" several entries stored.On the one hand, the SIP address (other addresses are also conceivable) on the other hand, the phone numbers of the fixed network connection or mobile phone connections Within the Home Zone, the mobile phone automatically connects to the Bluetooth Access Point, which typically has a 20 to 30 meter radius in the area, and is highly dependent on the power of the transmitter and receiver The mobile phone preferably connects automatically to the Blutooth Access Point as soon as it enters the Home Zone, and a connection is set up with the Bluetooth Access Point according to a defined profile (pairing) the login information (Sip account information) to the Bluetooth Access Po be transmitted int, so that this occurs as a client, the phone only takes over the function of the headset. Between the blood flow access point and the phone are then only transmitted simple audio data, as they are usually exchanged between a phone and a well-known Blutooth headset. The actual codec calculation, as it is necessary to communicate through the packet-oriented network, is done through the access point. In an alternative embodiment, this can also be done on the mobile phone itself. Then the Bluetooth access point serves merely as another IP router.

Further be through the mobile phone via bluetooth selected Transmit data, like the address of the communication partner, the keyboard codes respectively Number codes as you dial incurred the keyboard. Once the mobile phone in the home zone is logged, the communication is preferably via the Bluetooth connection. On the basis of a decision table can also be a Alternative connection via GSM or a call-through gateway, in front of the actual Number automatically a 0800 is selected. This can provide a faster or cheaper network for establishing a connection made available become. Before a call is made it checks if the communication partner online or present is. This is the presence status continuously updated or the Bluetooth Gateway checks this regularly and only sends status changes to the phone. In a preferred embodiment, the presence status becomes Once updated by all users when the mobile phone on the Bluetooth gateway (or RG) logs. It can also be a communication be done in advance with the RG before a call through which only the presence status of the communication partner is queried shortly before the call. These Data can also cache the RG. When there is a call to go outside based on a decision table, which is preferably arcuate is checked over the most sensible way to contact is. This is of course taken into account what type of mobile phone contract the user owns the mobile phone. Further is taken into account at which service provider the communication partner registered is. For example, e.g. a communication between different network providers very expensive. In such a case, it often makes more sense to take an alternative communication path. Thus, in addition to Phone number provided the option to deposit the network providers. Because of the possibility taking a phone number is no longer clear these days recognizable by the telephone number, in which network the communication partner sign up.

Of the 6 shows a flowchart showing the networks over which the communication has to be made. As soon as a call is to go out, it is checked on the basis of the dialed number or the selected persons whether an alternative number or communication address for this person is provided in the telephone book. The Verification takes place when the call has to go out. If a communication address exists, it is checked whether the receiver is present in the network. If it is not present, it checks whether a flat rate exists and whether the receiver is in the same network, or in a network by the flat rate is applied. If this is not the case then a call will be made via a 0800 number as shown.

7 Shows the data flow as soon as the phone is in the home zone, ie. In the zone in which a connection to the RG can be established. In the first step, an application is made to the RG, which then transmits a corresponding declaration to the server. This transmits the stored list of communication friends and additionally a list of presence information for communication partners whose addresses are stored in the telephone book.

to Avoiding blockages through a firewall, uses the Bluetooth Gateway an encrypted Communication (SSH, SSL) using other Bluetooth gateways Construction can or with a proxy that is located on the Internet especially for this Task. In an alternative embodiment, too variable port numbers are used, so restrictions through firewalls or other blocking systems, as they especially often in hotels or other public facilities be used to suppress Internet telephony, can be avoided.

In a further embodiment the correct characteristics of the Bluetooth GUS are aligned designed so that the Bluetooth signal transmitted to the phone becomes. A corresponding training can also be made in the mobile phone by appropriate Parameter settings of the Bluetooth receiver are taken into account.

The preferred embodiments serve for understanding of the invention and do not constitute a limitation of the invention The scope of protection is determined solely by the following claims.
