Technical field

The present invention relates in public communication network, support the method and system of short code dialing (short code dialing).More specifically, the present invention relates to provide the service of ENUM or similar ENUM domain name service (DNS) in the public communication network environment, to carry out callee's short code method for communicating and system.

Background technology

In wireline telecommunication network, subscriber exchange (PBX) is the form of the scale down of all central office exchanges (central office switch) of (with respect to public telephone company) private sector.The feature that PBX provided is: allow the member by user's group that PBX served, dial the shortening form (being called as short code) of other members' complete E.164 directory number.Depend on the particular network realization, E.164 the number of form is generally 10 to 15 figure place word lengths, and can comprise that the national code identifier is formed part, domestic destination sign indicating number identifier is formed part and identification code composition part and Subscriber Number part.In the U.S., these short dialing sign indicating numbers are generally seven or the last 4-digit number of the E.164 telephone number of tens word.Use these short dialing sign indicating numbers do not need the group membership remember complete seven or the E.164 telephone number of tens word get in touch other group membership.Should be appreciated that, based on the short code of PBX only with the environmental correclation of specific subscriber exchange, this subscriber exchange is as the main frame of the whole number number of correspondence.In other words, if the user who is served by the terminal station or the mobile switching centre of public switch telephone network (PSTN) dials, then possibly can't successfully finish calling based on the short code of PBX.

The common U.S. Patent number of transferring the possession of 7,072,678 discloses the method and system of supporting short code dialing in the public communication network such as GSM or IS-41 wireless network.Be used for moving a determinant attribute organizing the short code that dials and be that it is unique that this short code need not at network.That is to say that user A can define the short code 111 that is associated with user B, and user C can define the identical short code value 111 that is associated with user D.That is to say that certainly, this is the situation of unconventional public whole number dialing/numbering plan also, in this traditional scheme, but each whole number dialed number is unique related with unique user.

In recent years, the Internet engineering duty group (IETF) had begun the E.164 exploitation of number mapping (ENUM) system, to make things convenient for interconnecting between communication network that relies on telephone number and the communication network that uses domain name service (DNS).Detailed description about the ENUM service sees also " IETF RFC 3761; April2004The is to Uniform Resource Identifiers (URI) Dynamic DelegationDiscovery System (DDDS) Application (ENUM) E.164 ", by reference its disclosed full content is incorporated in herein.Especially, the ENUM system can be mapped as one or more unified resource identifiers (URI) in DNS with being called as the particular number of number E.164.URI is the character string of identifying resource, and described resource for example is other resources of document, image, file, database, e-mail address, website or universal architecture form or service etc.URI can comprise SIP URI, instant message (IM) identifier, e-mail address identifier, the Internet chat identifier and IP address.

The ENUM conversion is based on the number of the complete number table that will dial.Therefore, ENUM conversion based on short code may be failed, in addition, because the ENUM service is converted to public URI with public DN, and because short code is general only just meaningful in dedicated network, so can not under situation, use short code individually by public URI sign called end point.

Therefore, in view of these problems that are associated with short code dialing, need a kind of improved method and system, in the communication network environment that comprises the ENUM Transformation Service in order to the function of short code dialing to be provided.
