Embodiment mono-
The embodiment of the present invention one provides the IU link method for releasing in a kind of PS territory, for when the current UE that carries out combination fields business is switched to second network from first network, the IU link in PS territory is discharged, and this combination fields business is CS territory business and PS territory business; This first network, for support the network of combination fields business (supporting to carry out CS territory business and PS territory business) simultaneously, includes but not limited to 3G network, for example TD-SCDMA network; This second network, for not supporting the network of combination fields business, includes but not limited to 2G network, for example GSM network; When the current UE that carries out combination fields business is switched to second network from first network, CS territory business can handover success, and PS territory business can not handover success, by the CS territory business of UE from first network is switched to second network (concrete handoff procedure repeat no more), as shown in Figure 3, the IU link method for releasing in this PS territory comprises the following steps:
Step 301, RNC waits for and receives IU RELEASE COMMAND message.
Step 302, if receive IU RELEASE COMMAND message before specifying timer expiry, RNC discharges the IU link in PS territory.
Step 303, if do not receive that IU RELEASE COMMAND message (is that core net is (as SGSN(Serving GPRS Supporting Node before specifying timer expiry, Serving GPRS Support Node) etc.) do not send out or send out evening IU RELEASE COMMAND message), RNC discharges the IU link in PS territory to core network requests, and carries IU link former because User inactive that discharges PS territory.
Based on this User inactive, follow-up webmaster can be not a call drop by the reason statistics of the IU link in current release PS territory, thereby has avoided the situation of wrong report call drop.
In the embodiment of the present invention, RNC discharges the IU link in PS territory to core network requests, comprising: RNC obtains current configuring condition; If current, be configured to the first configuration, RNC discharges the IU link in PS territory to core network requests, and carries IU link former because User inactive that discharges PS territory; If current, be configured to the second configuration, RNC discharges the IU link in PS territory to core network requests, and carries IU link former because the call drop in combination fields service switch process that discharges PS territory.

Due to uses such as current protection timer (being the timer that current wait receives IU RELEASE COMMAND message) and reorientation (single domain and two territory), intersystem handovers (single domain and two territory) are all durations of IU mouth TeocationOverAll; and at the overtime message id of timer internal (sign), be also the same, therefore cannot distinguish the timer under different situations at present.
Therefore, in the embodiment of the present invention, in the handoff procedure of combination fields business between first network and second network, independent appointment timer (Iu Timer) is set, this specifies timer is to wait for that for PS territory core net sends the timer of IU RELEASE COMMAND message; And this specifies the duration parameters of timer configurable, according to the actual situation that sends IU RELEASE COMMAND message of different core network (as the SGSN of different provinces and cities), be configured, can realize flexible configuration.
The process that is switched to second network from first network at the current UE that carries out combination fields business shown in Fig. 4 of take is example, while not receiving IU RELEASE COMMAND message before Iu Timer is overtime, RNC sends IU RELEASE REQUEST(request to SGSN, i.e. request discharges the IU link in PS territory), wherein carry IU link former because User inactive that discharges PS territory.
In sum, in the embodiment of the present invention, RNC is when discharging the IU link in PS territory to core network requests, it carries IU link former because User inactive that discharges PS territory, thereby making webmaster can be not a call drop (the irrational call drop statistics that is about to this kind of reason weeds out) by the reason statistics of the IU link in current release PS territory based on this reason (being User inactive), then avoid the situation of wrong report call drop, and provide call drop data accurately for network optimization work.
Further, compared with prior art, because PS territory business can not reorientation during success, current PS territory business can be hung up, and again recover PS territory business after waiting for CS territory service ending, for user impression, be impression less than this call drop, by the reason statistics of the IU link in current release PS territory, be not therefore that a call drop is rational.As shown in Figure 5, for schematic flow sheet is hung up/recovered to PS territory business, when UE is in GPRS(General Packet Radio Service, general packet radio service) during grouped data transmission state, if be required, enter GSM dedicated mode, and because the restriction of UE can not be communicated by letter it on GPRS channel, UE should ask network to hang up gprs service, after dedicated mode finishes, then the transmission that recovers data.
