摘要
A major drawback of current methods for identifying the subscriber type of IP and non-IP subscribes with SIP is that additional signaling elements have to be added in casting SIP headers. The present invention provides a method for identification of subscriber type with SIP in which the originating subscriber UIJls are in form of userpart@ hostpart, the userpart uniquely identifying the originating subscriber (SUBa, SUBe); the present invention comprising, by a first switch (SSI), identifying itself to a. second switch (SS2) through the hostpart; by the first switch (SSI) signaling via SIP to a second switch (SS2) the originating subscriber-type by using the hostpart to define a logical grouping identifying the originating subscriber-type.
