Embodiment
As shown in Figure 1, the method for a kind of reminding session that the embodiment of the present invention provides, can comprise the following steps:
Step 101: receive the conversation request message sending by Session initiation Protocol (SIP), call property is carried in this session request;
Terminal called can receive the SIP conversation request message that calling terminal is initiated by SIP service node, carries the call property that calling terminal or SIP service node add in this SIP conversation request message.Wherein, this call property can comprise charging policy, call priority, significance level, urgency level, mood sign etc.Terminal called can be the equipment such as user agent (User Agent, UA), terminal.
In realizing a specific embodiment of the present invention, call property can carry by expansion SIP conversation request message, and concrete extended mode is as follows:
Mode one: in SIP conversation request message, increase a header field, all-calls attribute is all carried in this header field, in header field, can comprise type and the value of call property, for example:
Call-Attribute:charging-policy=freephone; Importance=is high; //Call-Attribute is the call property header field of expansion: charging-policy=freephone; Importance=height be the call property type of carrying in Call-Attribute header field with and value.
Mode two: for each call property is set up a header field, each expansion header field carries a call property, can only include the value of the corresponding call property of this header field, for example in header field
Charging-Policy: freephone;
Importance: height; // " Charging-Policy " " Importance " is the call property header field of expansion, and " freephone " " height " is for being respectively the value of Charging-Policy and Importance.
Be understandable that the method for carrying call property in conversation request message can have a variety of, above-mentioned to carry call property method should not be construed as for example method exhaustive that carries call property.
Step 102: resolve above-mentioned conversation request message and obtain call property;
Concrete, terminal called is when resolving above-mentioned conversation request message, can be by searching the call property header field in conversation request message, then read the value in the call property that call property header field comprises, thus the call property that obtains carrying in conversation request message.
In addition, in conversation request message, can also carry effective call property sign, before searching call property header field, can also elder generation according to this effective call attribute-bit, judge in this conversation request message, whether to include effective call property, if any, then carry out search operation.Concrete, support (Supported) header field that can add call property in conversation request message indicates whether include effective call property.Called end receives after above-mentioned Supported header field, read Supported header field parameter and judge whether this conversation request message includes call property, can avoid like this not comprising in conversation request message and when call property or all-calls attribute are sky, search call property.
Step 103: carry out corresponding reminding session according to above-mentioned call property.
In a specific embodiment, terminal called can pre-stored call property and the corresponding relation of alerting pattern, concrete, the configuration information that terminal called is inputted by receiving terminal user, according to this configuration information, generate call property and alerting pattern corresponding relation, and store.Wherein, this corresponding relation can be stored with the form of table, as, shown in table 1:
Table 1
Be understandable that, above-mentioned alerting pattern can further include the tinkle of bells of ring and the content of prompting, and different call properties also can corresponding same alerting pattern, above-mentioned alerting pattern be only of the present invention one for example.In addition, the method for setting up corresponding relation also can have a variety of, the above-mentioned method of should not be construed as for example of mapping table being set up to corresponding relation exhaustive.
When terminal called receives the conversation request message of carrying call property, can be according to the content of call property, inquire about above-mentioned corresponding relation, obtain the alerting pattern corresponding with call property (as, determine the content of whether ring and prompting user and definite ring and prompting), and adopt the alerting pattern getting to carry out reminding session.For example: if comprise charging policy in call property, when charging policy value is freephone, adopt the mode of vibration+prompting, to user, pointing out charging policy is freephone, if comprise significance level in call property, when significance level is while being high, according to user's configuration, determine whether to break through user's Presence and the setting such as quiet, still this is an important phone to play significance level bell sound reminding user, if comprise mood sign in call property, show mood sign, if comprise above multinomial in call property simultaneously, according to user's configuration, carry out one or more promptings and ring.
The embodiment of the present invention is by carry call property in SIP conversation request message, and according to this call property, carries out corresponding reminding session at terminal called, realized the personalization of reminding session.And called subscriber can remind the type that identifies session according to personalization, efficiency and the validity of calling out have been improved.
In the embodiment of the present invention, the handling process that calling terminal carries call property in SIP conversation request message as shown in Figure 2, comprising:
Step 201: terminal receives the instruction that user initiates SIP session request, the call property and the terminal called that in this instruction, carry appointment identify.
In a specific embodiment, can, by increase the option of " call property is set " in the call option of terminal, offer user and carry out call property setting.
Step 202: terminal generates the SIP conversation request message of carrying call property according to this instruction.
Concrete, terminal can be carried this call property by expansion SIP conversation request message, as two kinds of extended modes below:
Mode one: increase a header field in SIP conversation request message, all-calls attribute is all carried in this header field, can comprise type and the value of call property in header field.
Mode two: for each call property is set up a header field, each expansion header field carries a call property, can only include the value of the corresponding call property of this header field in header field.
Be understandable that the method for carrying call property in conversation request message can have a variety of, above-mentioned to carry call property method should not be construed as for example method exhaustive that carries call property.
Step 203: the SIP conversation request message of carrying call property is sent to receiving side terminal by SIP service node, so that receiving side terminal carries out corresponding reminding session according to the call property receiving.
In concrete application, SIP conversation request message the SIP node of process can also modify to the call property in SIP conversation request message, for example, increase, delete call property etc.As shown in Figure 3, this processing procedure can comprise the following steps:
Step 301: receive the conversation request message sending by SIP; Call property is carried in above-mentioned session request;
SIP service node receives the SIP conversation request message that calling terminal is initiated, and carries the call property that calling terminal or upper level SIP service node add in this SIP conversation request message.Wherein, this call property can comprise charging policy, call priority, significance level, urgency level, mood sign etc.
The concrete carrying mode of call property can, with reference to the description of middle step 101 part embodiment illustrated in fig. 1, repeat no more here.
Step 302: above-mentioned call property is revised as to the call property that the CAMEL-Subscription-Information with user matches according to user's CAMEL-Subscription-Information;
