If the described method that sip message in the communication network is filtered is applied in the network configuration shown in Fig. 2 a, suppose that MS102a is a message sink equipment, MS101d is the message transmitting apparatus, CSCF106 comprises I-CSCF, S-CSCF and P-CSCF (Fig. 2 b does not show above-mentioned three), and the information flow of this method as shown in figure 11 so.With reference to Figure 11, information flow comprises: 1:MS101d sends SIP MESSAGE message to MS 102a.According to the network address that this MS102a user belonged to as can be known, address of MS102a,, this SIP MESSAGE message is sent to the I-CSCF of described MS102a user place home network according to IMS network routing rule.After 2:I-CSCF receives SIP MESSAGE message, according to the user ID of the purpose side of carrying in this SIP MESSAGE message (being MS 102a), inquire about the S-CSCF positional information of the present registration of this MS102a user to the HSS104 of MS102a user place home network.3:HSS104 finds the current S-CSCF address information of registering of MS102a user, and returns to I-CSCF according to the user ID of MS102a.After 4:I-CSCF receives the current S-CSCF address information of registering of MS102a, described SIP MESSAGE forwards is made subsequent treatment to this S-CSCF.After 5:S-CSCF receives SIPMESSAGE message, remove to search MS102a user's CAMEL-Subscription-Information to above-mentioned HSS104.6:HSS104 finds its CAMEL-Subscription-Information according to MS102a user's user ID, and finds this user message screening business of having contracted.HSS104 sends to S-CSCF with user signing contract information, comprises the CAMEL-Subscription-Information of message screening business, wherein can contain the address information of MFS200a.After 7:S-CSCF receives user signing contract information from HSS104, find this user message screening business of having contracted, the SIPMESSAGE forwards that then will receive in 5 is given MFS200a.S-CSCF obtains the mode of the address information of MFS200a, can also can pass through network configuration, the address information of pre-configured MFS200a in S-CSCF for obtaining the CAMEL-Subscription-Information that returns from HSS104.8:MFS200a filters the SIP MESSAGE message of receiving from S-CSCF according to the MS102a user's who preserves on it filtering rule.The SIP MESSAGE message of having only filtering rule to allow to send just can be replied to S-CSCF.9:MFS200a replaces MS 102a to reply 200OK message to MS101d, thus MS101d can not know the message of its transmission and whether filtered by MFS200a, thereby avoided malice to repeat to send.10:S-CSCF receives the SIP MESSAGE message by filtering from MFS200a, and the business of carrying out other sends to the P-CSCF that registers at MS102a after triggering and handling.11:P-CSCF gives MS102a with SIP MESSAGE forwards.After 12:MS 102a receives SIP MESSAGE message, reply 200OK message and give P-CSCF.13:P-CSCF gives S-CSCF with the 200OK forwards.14:S-CSCF gives MFS200a with the 200OK forwards, has received SIP MESSAGE message to notify its MS102a.If MFS200a finds not receive 200OK message for a long time, then can carry out retransmission process, can send on the MS102a to guarantee the SIPMESSAGE message that process is filtered.
The mode of configuration messages filtering rule mainly includes but not limited to following three kinds on described message screening server, is example with Fig. 2 a, disposes on MFS200a and can pass through about the message screening rule of MS102a:
1, MS102a sends to MFS200a with described message screening rule.For example, adopt existing sip message mechanism, described message screening rule is sent to MFS200a with the Body field of existing SIP MASSAGE as carrier; Can also realize by defining new sip message.
2, use the contracted user of MS102a to login MFS200a, on the HTTP of MFS200a service page, the message filtering rule is configured by the HTTP mode.
3, in IMS network 100a, record in the network node (for example HSS104 among Fig. 2 or HLR105) of MS102a CAMEL-Subscription-Information and preserve described message screening rule, and MFS200a obtains described message screening rule by the communication between network entity from HSS104 or HLR105 with signatory form.MFS200a can obtain described message screening rule by following manner:
1) regularly more newly downloaded.MFS200a sets and upgrades timer, and when this upgraded the timer triggering, MFS200a just downloaded described message screening rule from HSS104 or HLR105.
When 2) described HSS104 or HLR105 detect described message screening rule and change, initiatively send message screening rule after changing to upgrade the message screening rule on the MFS200a to MFS200a.
3) MFS200a is known when MS102a registers in IMS network 100a, and to HSS 104 or HLR105 request message filtering rule, HSS104 or HLR105 receive that this request back sends described message screening rule to MFS200a.
4) MFS200a need be when MS102a sends message, to go up the message screening rule of storage identical with HSS 104 or HLR105 for the message screening rule that detects earlier self storage, if inequality, just download the message screening rule to upgrade the message screening rule on the MFS200a from HSS104 or HLR105.
In a specific embodiment of the present invention, what described sip message specifically adopted is SIP MESSAGE message.Certainly, the sip message of other type also can be applied to the present invention.
By above-mentioned explanation, in communication network by this network entity of message filter (promptly can be that physical entity also can be a logic entity) is set, the sip message combination that sends to message sink equipment is filtered about the message screening rule of this sip message receiving equipment, only the sip message that the message screening rule is allowed sends to described message sink equipment, thereby avoided holding in the communication network contracted user's bothering of message sink equipment by own defined rubbish message, the health of sip message content in the communication network is provided, has avoided the unhealthy information content in communication network, to scatter propagation.
Above disclosed only is the preferred embodiments of the present invention, can not limit the present invention's interest field certainly with this, and therefore the equivalent variations of being done according to the present patent application claim still belongs to the scope that the present invention is contained.
