A method for managing service voices in a bearer and control separated network, wherein said method comprises: determining (100, 300), by a Media Gateway Controller "MGC", a service voice to be broadcast, wherein service voice is assigned an identifier, wherein the identifier comprises an identifier of the operator to which the service voice belongs, an identifier of a service category to which the service voice belongs and a number of the service voice in the service category the service voice belongs to when said identifier is a text identifier, or wherein the identifier comprises the number of the service voice in the service category it belongs to when said identifier is a numeric identifier; determining (110-140, 310), by the MGC, the operator to which the service voice to be broadcast belongs, the service category to which the service voice to be broadcast belongs, and the number of the service voice to be broadcast in said service category, and a storage location of a record file corresponding to the service voice to be broadcast; hierarchically combining (170, 320), by the MGC, the identifier of the operator, the identifier of the service category, the number of the service voice to be broadcast and the storage location of the record file into an URL address; sending, by the MGC, said URL address as a service voice broadcasting request to a Media Gateway, MGW; upon receiving said service voice broadcasting request, parsing out (200-240, 330), by the MGW, from the URL address contained in the service voice broadcasting request, the operator to which the service voice to be broadcast belongs, the service category to which the service voice to be broadcast belongs, the number of the service voice to be broadcast in the service category it belongs to, and the storage location of the record file corresponding to said service voice; retrieving (270, 340), by the MGW, the record file corresponding to the service voice to be broadcast according to said parsed information; transforming (280, 340), by the MGW, said record file into a tone code and then sending the tone code to a tone board for broadcasting. determining (100, 300), by a Media Gateway Controller "MGC", a service voice to be broadcast, wherein service voice is assigned an identifier, wherein the identifier comprises an identifier of the operator to which the service voice belongs, an identifier of a service category to which the service voice belongs and a number of the service voice in the service category the service voice belongs to when said identifier is a text identifier, or wherein the identifier comprises the number of the service voice in the service category it belongs to when said identifier is a numeric identifier; determining (110-140, 310), by the MGC, the operator to which the service voice to be broadcast belongs, the service category to which the service voice to be broadcast belongs, and the number of the service voice to be broadcast in said service category, and a storage location of a record file corresponding to the service voice to be broadcast; hierarchically combining (170, 320), by the MGC, the identifier of the operator, the identifier of the service category, the number of the service voice to be broadcast and the storage location of the record file into an URL address; sending, by the MGC, said URL address as a service voice broadcasting request to a Media Gateway, MGW; upon receiving said service voice broadcasting request, parsing out (200-240, 330), by the MGW, from the URL address contained in the service voice broadcasting request, the operator to which the service voice to be broadcast belongs, the service category to which the service voice to be broadcast belongs, the number of the service voice to be broadcast in the service category it belongs to, and the storage location of the record file corresponding to said service voice; retrieving (270, 340), by the MGW, the record file corresponding to the service voice to be broadcast according to said parsed information; transforming (280, 340), by the MGW, said record file into a tone code and then sending the tone code to a tone board for broadcasting.
