Embodiment
For fear of between Target RNC and Serving RNC owing to there is not an Iur interface; perhaps the signaling link of Iur interface breaks down; the situation that RNC internal resource and UE communication context information are suspended at SRNC appears; the present invention comes the active state of monitoring UE by the mode that the protection timer is set in RNC inside; and, discharge related resource and the communication context information of the inner UE of SRNC protecting timer expiry to start exception handling procedure later on.
In 3GPP TS25.331 agreement, UE timer internal T305, T302 and T307 have been defined, internal counter N302, purpose is to guarantee that UE is under the CELL-FACH/CELL-PCH/URA-PCH state, can periodically initiate CELL UPDATE process, and can't obtain in CELL UPDATE process making the own returning to idle mode of UE under the situation of network side response.
SRNC is provided with protection timer (Tmonitor) for the UE of each access network, and its duration needs the value of T305, T302, T307 and N302 in the reference cell.Whenever Serving RNC enters the CELL-FACH/CELL-PCH/URA-PCH state by RRC signaling message notice UE, this protection timer will start thereupon.
Referring to Fig. 1, wireless access network internal resource guard method of the present invention is described.
Step 101, UE has set up Radio Resource control (RRC) and has connected;
Step 102, Serving RNC are initiated an air interface RRC signaling procedure (SRNC enters CELL-DCH or CELL-FACH or CELL-PCH or URA-PCH state by RRC signaling message notice UE), and successfully finish.
Step 103, Serving RNC judge whether the RRC state of UE is CELL-FACH or CELL-PCH or URA-PCH, if execution in step 104 then, otherwise finish.
Step 104, Serving RNC start the protection timer, so the prerequisite of trigger protection timer is: after SRNC enters CELL-FACH or CELL-PCH or URA-PCH state by RRC signaling message notice UE.
Step 105, Serving RNC expectation was received RRC message---CELL UPDATE message or RNSAP signaling message UPLINK SIGNALLING TRANSFERINDICATION from UE in the past at the protection timer expiry.If before the protection timer expiry; SRNC has received from the CELL UPDATE message of UE or Iur interface RNSAP signaling message UPLINK SIGNALLING TRANSFER INDICATION; then further execution in step 106; if before the protection timer expiry; SRNC does not receive the RRC message from UE---CELL UPDATE message or RNSAP signaling message UPLINK SIGNALLINGTRANSFER INDICATION, then execution in step 120.
Step 106 is further judged the result of cell updating course, if UE still remains on the CELL-FACH/CELL-PCH/URA-PCH state, then execution in step 107, otherwise execution in step 110.
Step 107, the protection timer resets and returns step 104, restarts the protection timer.
Step 110 enters the CELL-DCH state if the result of cell updating course is UE, then protects timer only to carry out reset operation and end process, optionally may restart the protection timer in subsequent process.
Step 106,107,110 has reflected two kinds of results that handle cell update.
Step 120; if protection timer expiry; SRNC does not receive from the CELL UPDATE message of UE or Iur interface RNSAP signaling message UPLINK SIGNALLING TRANSFER INDICATION; then SRNC will think that UE is out of touch with network side; start exception handling procedure; initiate RRC on the CCCH in the Serving cell of the current place of the UE that SRNC write down and connect dispose procedure; initiate the internal resource dispose procedure then; and removing UE communication context information, end process then.
The duration of protection timer (Tmonitor) can be determined by several different methods, for example, can be the various combination of timer T305, T307, T302 and counter N302, also can determine an empirical value according to test.Wherein a kind of calculating formula of timer duration of protecting is:
Tmonitor=T305 * 60+T302 * N302/1000+T307, unit: second.
Method provided by the invention; can be under the situation that does not rely on Iur interface between RNC; by the mode of protection timer is set for the UE of access network in RNC inside; realization is to the protection of wireless access network internal resource; avoid the hang-up of RNC internal resource and UE communication context information, help the reliability service of RNC equipment.
