Embodiment
Channel handoff procedure in the embodiment of the invention can be that user terminal is initiated as required temporarily, perhaps also can be the strategy according to user terminal or network, has set after regularly channel is watched, and the channel of being initiated by network side or user terminal switches.
For making the purpose, technical solutions and advantages of the present invention clearer, below in conjunction with embodiment and accompanying drawing, the present invention is described in more detail.
Fig. 1 is the exemplary process diagram of the report method of embodiment of the invention mid band switching result.As shown in Figure 1, this flow process comprises the steps:
When the channel switching takes place, user terminal sends channel switch request to basic forwarding capability/basic control function entity (EFF/ECF), EFF/ECF carries out scope check according to the channel authority information of the user terminal that obtains to the channel switch request from user terminal.If scope check passes through, then the port at user terminal place is duplicated the multicast data flow data of new channel, receive new Media Stream for user terminal.As seen, user terminal and EFF/ECF all can be known channel switching result, so the channel switching result in the present embodiment reports process that following two kinds of situations can be arranged:
Situation one: it is user terminal that channel switching result reports entity.Be that user terminal directly reports SCF with the channel switching result of self.During specific implementation, when user terminal to send up was given SCF, other network entity also can be passed through in the centre, but other network entity can carry out transparent transmission by a channel switching result with user terminal, and do not process, therefore can be called for short is that user terminal directly reports SCF with the channel switching result of self.Also can there be similar situation in following situation in the present embodiment.
Situation two: it is P-CSCF that channel switching result reports entity, and then the P-CSCF mode of obtaining the channel switching result of user terminal can have two kinds.Mode one: P-CSCF obtains user terminal and switches self the channel switching result that reports after finishing at channel; Mode two: P-CSCF obtains the channel switching result of the user terminal of being accepted that EFF/ECF that RACS transmits reports.Mode three: P-CSCF obtains the channel switching result of the user terminal of being accepted that EFF/ECF reports.Respectively above-mentioned three kinds of modes are described in detail below.
Mode one: user terminal reports P-CSCF with the channel switching result of self after finishing the channel switching.
Give the correct time on concrete, user terminal can report by dialogue-based initializtion protocol (SIP).And can be after finishing the channel switching, directly the channel switching result with self reports P-CSCF; Perhaps also can after finishing channel and switching, start default timer, and before this timer expiry, not carry out new channel when switching, self channel switching result is reported P-CSCF.Further, before this timer expiry, carried out new channel and switched, then restarted timer, and before this timer expiry, do not carried out new channel when switching, self channel switching result has been reported P-CSCF.
Mode two: EFF/ECF reports RACS with the channel switching result of the user terminal accepted, by RACS the channel switching result of user terminal is reported P-CSCF.
Wherein, when EFF/ECF reported RACS with the channel switching result of the user terminal accepted, after can switching at the channel of accepted user terminal, the channel switching result with user terminal reported RACS immediately; Perhaps also can be after the channel of accepted user terminal switches, start default timer, and when before this timer expiry, not receiving the new channel switch request of described user terminal, the channel switching result of user terminal is reported RACS.
Further, before this timer expiry, receive the channel switch request that this user terminal is new, then restart timer, and when before this timer expiry, not receiving the new handoff request of described user terminal, the channel switching result of user terminal is sent to RACS.
Equally, when RACS reports P-CSCF with the channel switching result of user terminal, can be after receiving the channel switching result of user terminal, the channel switching result with user terminal reports P-CSCF immediately; Perhaps also can be after receiving the channel switching result of user terminal, start default timer, and when before this timer expiry, not receiving the new channel switching result of described user terminal, the channel switching result of user terminal is reported P-CSCF.
Further, before this timer expiry, receive the channel switching result that this user terminal is new, then restart timer, and when before this timer expiry, not receiving the new channel switching result of described user terminal, the channel switching result of user terminal is reported P-CSCF.
Wherein, user terminal is initiated channel switch request based on Internet Group Management Protocol (IGMP).
Mode three: EFF/ECF directly reports P-CSCF with the channel switching result of the user terminal accepted.
Wherein, when EFF/ECF reported P-CSCF with the channel switching result of the user terminal accepted, after can switching at the channel of accepted user terminal, the channel switching result with user terminal reported P-CSCF immediately; Perhaps also can be after the channel of accepted user terminal switches, start default timer, and when before this timer expiry, not receiving the new channel switch request of described user terminal, the channel switching result of user terminal is reported P-CSCF.
Further, before this timer expiry, receive the channel switch request that this user terminal is new, then restart timer, and when before this timer expiry, not receiving the new handoff request of described user terminal, the channel switching result of user terminal is sent to P-CSCF.
Wherein, user terminal is initiated channel switch request based on Internet Group Management Protocol (IGMP).
In this step, specifically report process to be: channel switching result reports entity to give SCF with the channel switching result of the user terminal that received by issue (PUBLISH) message in the Session Initiation Protocol or information (Info) message or instant (Message) information reporting.
Perhaps, if it is not unique providing professional SCF in the group network system, and centrally may pass through a plurality of application servers, SCF then in order to guarantee that channel switching result information can arrive provides professional, can report the channel handover event of entity subscribes user terminal in the present embodiment by SCF in advance to channel switching result, then in this step, channel switching result reports entity the channel switching result of the user terminal that received can be reported the SCF of the channel handover event of having subscribed to user terminal.Specifically report process the channel switching result of the user terminal that received to be given the SCF of the channel handover event of having subscribed to user terminal by the Notify information reporting in the Session Initiation Protocol for: channel switching result reports entity.
Further, the SCF in the present embodiment can be further after receiving the channel switching result of user terminal, need determine whether the change session, if desired, and the modification process of initiation session then.Because channel switches the variation that may cause resources such as QoS, bandwidth, can be invited with the transmission of satisfying the new channel content this moment by the modification process of SCF active initiation session.
