Problems solved by technology

[0005] In the research of the prior art, the present inventor found that although "find-me" can realize one number, the work of "find-me" is completely completed by the proxy, which increases the system overhead of the proxy

Embodiment 1

[0066] Embodiment one, see image 3 , this embodiment specifically includes the following steps:

[0067] Step 301: When receiving a call request from a calling party, the proxy sends a call message and at least address information containing other SIP UA addresses registered by the user to the first SIPUA of the called user.

[0068] Step 302: When the first SIP UA does not answer the call message, it sends a call transfer message to the second SIP UA corresponding to an address in the address message.

[0069] Step 303: The first SIP UA deletes the address information of the second SIP UA from the address information, and sends the modified address information to the second SIP UA.

[0070] It should be understood that: in one implementation, step 302 and step 303 do not have a necessary sequence, and it may also be that when the first SIP UA does not answer the call message, the first SIP UA transfers the address information of the second SIP UA from The address informati...

Embodiment 2

[0073] see Figure 4 , Embodiment 2 of the present invention comprises the following steps:

[0074] Step 401: When receiving a call request from the calling party, the proxy sends a call message to the first SIPUA of the called user and at least address information containing the address information of other SIPUAs registered by the user relative to the first SIP UA.

[0075] Step 402: When the first SIP UA does not answer the call message, send a call forwarding message to the second SIP UA corresponding to one of the other SIP UA addresses in the address information.

[0076] Step 403: the first SIP UA sends the address information to the second SIP UA;

[0077] In one implementation, the first SIP UA may send to the second SIP UA address information including at least the address of the SIP UA that has not been paged.

[0078] Step 404: the second SIP UA checks whether there is its own address in the received address information, and if so, deletes its own address.

Abstract

The invention discloses a method, a device and a system for one-number-service calling. The method for one-number-service calling comprises the following steps: a call request and the address information of other corresponding SIP UA addresses at least containing a first SIP UA are sent out to the first SIP UA of an SIP UA group corresponding to a called party correlated with the call request according to the address information of the SIP UA group registered by maintained users when the call request of a calling party is received; and the call request is transferred to a second SIP UA corresponding to an SIP UA address in the received address information when the first SIP UA does not respond to the call request. According to the embodiments of the invention, SIP UAs can participate in the services and independently select service flows. A proxy only sends out one call request information in the process, and all subsequent flows are finished by the SIP UAs so as to greatly reduce thesystem overload of the proxy.

Description

technical field [0001] The invention relates to the technical field of communication, in particular to a one-number calling method, device and system. Background technique [0002] Session Initiation Protocol (SIP) is getting more and more attention in the field of telecommunication technology, especially when SIP is used as the third generation mobile system signaling protocol to provide IP multimedia services, more and more telecommunication equipment suppliers are researching in the field of SIP A lot of manpower and material resources have been invested in development and development, and various SIP-based service solutions have been proposed. [0003] SIP supports mobility, and SIP-based communication devices are becoming more and more abundant. Especially for enterprise users, each employee often has a variety of SIP terminals: SIP phones on desks, SIP soft phones on computers, and SIP mobile phones , therefore, in this scenario, the "one number" service is very usefu...
