Abstract

A method for implementing Customized Ringing Signal (CRS) services is provided. The method includes: receiving a call request initiated by a caller terminal; obtaining a policy of playing a CRS tone according to the call request, where the policy is a policy of playing a CRS tone, namely, a caller CRS tone or a callee CRS tone, or a policy of filtering the CRS tone; and playing the CRS tone to a callee according to the policy. By setting a policy of playing the CRS tone to the callee in the network or the callee terminal, the users enjoy the CRS services at their own discretion.

playing the CRS tone according to the parsed result.

7. The method of claim 6, further comprising:

displaying or downloading one of a CRS media resource including at least one of a caller CRS media resource and a callee CRS media resource.

8. The method of claim 4, playing the CRS tone to the callee further comprising:

determining that the caller CRS tone needs to be played according to the call request and the policy of playing the CRS tone;

by the caller CRS AS;

performing caller CRS media negotiation according to the identifier of the caller CRS tone; and

instructing a caller Media Resource Server, MRS, to play the caller CRS tone to the callee.

9. The method of claim 4, playing the CRS tone to the callee further comprising:

determining that the callee CRS tone needs to be played according to the call request and the policy of playing the CRS tone;

performing callee CRS media negotiation; and

instructing a callee MRS to play the callee CRS tone to the callee.

10. The method of claim 4, wherein the playing the CRS tone to the callee according to the policy of playing the CRS tone comprises:

determining that the caller CRS tone needs to be played according to the call request and the policy of playing the CRS tone, and

sending one of a caller CRS media resource and an address of the caller CRS media resource to the callee terminal to play the caller CRS tone to the callee.

11. The method of claim 4, wherein the playing the CRS tone to the callee according to the policy of playing the CRS tone comprises

determining that the callee CRS tone needs to be played according to the call request and the policy of playing the CRS tone, and

sending one of a callee CRS media resource and an address of the callee CRS media resource to the callee terminal to play the callee CRS tone to the callee.

12. The method of claim 1, wherein the CRS tone includes one of callee and caller CRS tones and one of the caller and callee CRS tones is filtered out according to the policy of filtering the CRS tone.

13. The method of claim 1, further comprising:

configuring the policy of filtering the CRS tone on one of a callee terminal, a CRS filter Application Server (AS), and a callee CRS AS.

14. The method of claim 12, wherein filtering the CRS tone according to the policy of filtering the CRS tone comprises:

determining, that at least one of the caller CRS tone and the callee CRS tone needs to be filtered out according to the policy of filtering the CRS tone;

sending, an identifier of the CRS tone to be filtered out to a CRS Application Server (AS); and

filtering out, by the CRS AS, the CRS tone corresponding to the identifier.

15. The method of claim 12, wherein filtering of the CRS tone according to the policy of filtering the CRS tone comprises:

determining that at least one of the caller CRS tone and the callee CRS tone CRS tone needs to be filtered out according to the policy of filtering the CRS tone; and

rejecting one of a CRS media negotiation, a download of a CRS media resource, and a playing of the CRS tone.

16. The method of claim 15, filtering the CRS tone according to the policy of filtering the CRS tone further comprising:

if determining that the caller CRS tone needs to be filtered out according to the policy of filtering the CRS tone, sending the identifier of the caller CRS tone to be filtered out to the caller CRS AS; and

filtering out, by the caller CRS AS, the caller CRS tone according to the identifier of the caller CRS tone to be filtered out;

if determining that the callee CRS tone needs to be filtered out according to the policy of filtering the CRS tone, sending the identifier of the callee CRS tone to be filtered out to the callee CRS AS; and

filtering out, by the callee CRS AS, the callee CRS tone according to the identifier of the callee CRS tone to be filtered out; and

if determining that the caller CRS tone and the callee CRS tone need to be filtered out according to the policy of filtering the CRS tone, sending the identifier of the caller CRS tone to be filtered out to the caller CRS AS and sending the identifier of the callee CRS tone to be filtered out to the callee CRS AS; and

filtering out, by the caller CRS AS, the caller CRS tone according to the identifier of the caller CRS tone to be filtered out; and
