It will also be understood that, the measurement configuration information can also include calling time in measurement result or the information such as report cycle, so that signal quality measurement result can repeatedly be reported by obtaining user equipment, or signal quality measurement result periodically is reported, but the embodiment of the present invention is not limited to this.

In embodiments of the present invention, second wireless network control node can be cut based on receiving for instruction Change and successfully accuse or message, determine that user equipment controls node from the first wireless network control node successful switch to second wireless network；Second wireless network controls node such as can also be based on measurement configuration information is received, and determines that user equipment controls node from the first wireless network control node successful switch to second wireless network, but the present invention is not limited thereto.

For example, when second wireless network controls node to receive the handoff completion message of user equipment transmission, second wireless network control node can determine that user equipment controls node from the first wireless network control node successful switch to second wireless network.

In embodiments of the present invention, wireless access standard can include GSM standards, WCDMA standards, LTE standards and Wi-Fi standards, and corresponding wireless network control node can include BSC, RNC, eN B and accessed node（Access Point, cylinder is referred to as " AP ").It should be understood that in embodiments of the present invention, wireless access standard can also include other standards, and corresponding wireless network control node can also include other control nodes, and the present invention is not limited thereto.

In S120, second wireless network controls node according to the measurement configuration information, indicates that the user equipment carries out this signal quality measured.

In embodiments of the present invention, the scheduled measurement duration that second wireless network control node for example includes according to the measurement configuration information, cell progress of the instruction user equipment to the first wireless access standard within the scheduled measurement duration is signal quality measured；Or the information such as second wireless network control node scheduled measurement duration, measurement frequency point and the threshold value that can be included according to the measurement configuration information, instruction user equipment carries out signal quality measured, and the embodiment of the present invention is not limited to this.For example, second wireless network control node according to the measurement configuration information include on call time or report cycle etc., instruction user equipment carries out that this is signal quality measured, and controls signal quality measurement result on node to the second wireless network.

In S130, second wireless network control node receives the user equipment and carries out at least one signal quality measured measurement result to the cell of the first wireless access standard.

It should be understood that, second wireless network controls node after measurement configuration information is received, the signal quality of the cell of the first wireless access standard can be measured for instruction user equipment according to the measurement configuration information to user equipment transmission measuring control information；User equipment carries out cell measurement according to measuring control information, it is possible to periodically control node report measurement results to second wireless network.For example, the measurement result can include the cell ID of measurement cell, and the cell measurement result etc., the measurement result is, for example, RSRP measurement results and/or RSRQ measurement results etc., the measurement result can also include other information, and the present invention is not limited thereto.

It should also be understood that user equipment can repeatedly control to tie according to measurement configuration information to second wireless network Point report measurement results, report a measurement result every time, and the measurement result is such as can include the mark of cell of the signal quality more than the first wireless access standard of threshold value, but the embodiment of the present invention is not limited to this.

In S140, before the scheduled measurement duration terminates, when second wireless network control node determines that the user equipment is migrated in the way of redirecting to the network of the first wireless access standard, and when each measurement result at least one measurement result that second wireless network control node is received includes the cell for the first wireless access standard that at least one signal quality is more than threshold value, second wireless network controls node to send switching announcement to the first wireless network control node, and the switching is accused for indicating too early handover information.

It should be understood that second wireless network control node can be according to information such as the ability of user equipment, the service priority of user equipment or service rates, it is determined that the user equipment is migrated in the way of redirecting to the network of the first wireless access standard.For example, when UE does not possess the ability of different system switching, but when possessing the ability of homologous ray switching, network just can only migrate UE to the network of another homologous ray in the way of redirecting；Or can be migrated for the high UE of service priority by the way of switching, to reduce the time delay of UE service disconnections；And can be migrated etc. for the low UE of service priority by the way of redirecting.

Before the scheduled measurement duration that measurement configuration information is indicated terminates, when second wireless network control node determines that user equipment is migrated in the way of redirecting to the network of the first wireless access standard, second wireless network control node assesses user equipment and carries out signal quality measured measurement result to the cell of the first wireless access standard.

It should be understood that, as long as second wireless network control node determines that user equipment is migrated in the way of redirecting to the network of the first wireless access standard, second wireless network control node will assessment of the measurement result, and be not required for cell or identical the first wireless network control node that user equipment migration is back to identical the first wireless access standard.When i.e. user equipment turns again to the network of the first wireless access standard, cell where the user equipment and cell before can be with identical, can also be different；And can be with identical for the wireless network control node that the user equipment is serviced, can also be different, but the present invention is not limited thereto.

If all indicating that the signal quality of the cell of at least one the first wireless access standard is more than threshold value in the measurement result that second wireless network control node is received every time, for example when each measurement result of at least one measurement result that second wireless network control node is received includes the cell for the first wireless access standard that at least one signal quality is more than threshold value, then second wireless network control node can send the blunt announcement of switching 4 to the first wireless network control node, to indicate too early handover information； If the measurement result that second wireless network control node is received every time not necessarily all includes the cell for the first wireless access standard that at least one signal quality is more than threshold value, then second wireless network control node can not feed back the too early handover information to the first wireless network control node.

In embodiments of the present invention, alternatively, the handover report is also carried for indicating too early handover information；Alternatively, the blunt announcements of switching ^ also include redirection information, and the redirection information is used to indicate that just the triggering reason of blunt announcement is to redirect to trigger for the switching.That is the handover report that is sent to the first wireless network control node of second wireless network control node, can be also used for notifying that the first wireless network control node handover report is due to redirect and triggering.

It should be understood that, in embodiments of the present invention, the cell ID for exceeding threshold value in the measurement result that can also include on user equipment is accused in the switching, it is inappropriate for indicating that the network of the first wireless access standard this time switches, next time is it is contemplated that be switched in other cells, so as to avoid occurring identical turkey in network again.

In embodiments of the present invention, the first wireless access standard can be with identical with the second wireless access standard, such as the first wireless access standard and the second wireless access standard are all switched to another cell in LTE system for LTE standards, i.e. user equipment from a cell；Alternatively, the first wireless access standard is different from the second wireless access standard, for example, the first wireless access standard is LTE standards, the second wireless access standard is UMTS standards.

When the first wireless access standard is different from the second wireless access standard, the migration of user equipment is referred to as different system switching.For example, as shown in Fig. 2 user equipment is from the network of the first wireless access standard（LTE network）Migrate to the network of the second wireless access standard（UMTS networks）, then again from the network of the second wireless access standard（UMTS networks）Migrate back network (the LTE networks of the first wireless access standard）.It should be understood that the embodiment of the present invention is only illustrated by taking the switching of different system as an example, but the present invention is not limited thereto, and the method for feedback information according to embodiments of the present invention can also be applied to the switching in the network system of identical standard.

It should also be understood that in embodiments of the present invention, term " wireless access standard network " or " wireless access standard cell " refer to the network or cell that standard is accessed with specific wireless, for example, " first is wireless Access standard network " represents that the network system has the first wireless access standard.

It should also be understood that in embodiments of the present invention, so-called " redirection " mode refers to that wireless network control node issues frequency to user equipment, user equipment searches for suitable cell on specified frequency, and initiates the foundation of business again.Influence of the migration pattern of this redirection to network is smaller；And, it is necessary to which source radio network control node and target radio network control node prepare resource in advance for switching mode, user equipment is linked into after the cell that source radio network control node is specified, business transmission can be directly carried out.

In embodiments of the present invention, UE returns the network of the first wireless access standard from the network migration of the second wireless access standard, can both be realized, and can also be realized by redirecting mode by switching mode.If UE controls the business in node not terminate in second wireless network, then second wireless network control node can be migrated UE to the network of the first wireless access standard by way of switching or redirecting；If UE controls the business in node to be in second wireless network, second wireless network control node can be migrated UE to the network of the first wireless access standard by way of redirection.

The situation not terminated for business of the UE in second wireless network controls node, if second wireless network controls node by way of redirection, UE is migrated to the network of the first wireless access standard, the triggering reason of the event is with being consistent to switch the UE triggering reasons migrated to the network of the first wireless access standard, such as being all due to channel quality reason or cell load reason, and need to return to the network of the first wireless access standard.Therefore, in this case, UE falls within a kind of pingpang handoff event, it is necessary to send handover report by the network that second wireless network controls node to be redirected back to the first wireless access standard.

But for the situation that business of the UE in second wireless network controls node is over, a kind of normal network operation behavior can be considered as, can be without sending handover report to the first wireless network control node.

Thus, in embodiments of the present invention, alternatively, as shown in figure 3, before handover report is sent to the first wireless network control node, this method also includes：

S150, it is determined that the use when being migrated in the way of redirection to the network of the first wireless access standard The business of family equipment proceeds.

Specifically, if before the scheduled measurement duration that the measurement configuration information includes terminates, user equipment is migrated in the way of redirecting to the network of the first wireless access standard；All include the cell that at least one signal quality is more than the first wireless access standard of threshold value in the measurement result that second wireless network control node is received every time；And second wireless network control node determines that user equipment business of the user equipment when being migrated in the way of redirection to the network of the first wireless access standard is not over, so second wireless network control node can send handover report to the first wireless network control node, to indicate too early handover information.

In embodiments of the present invention, second wireless network control node determines that the service ending of user equipment can include following two situations：The first situation is the inactivity timer time-out that second wireless network control node detects UE.UE inactivity timer is used for the active situation that second wireless network controls node to monitor UE, when UE does not have data transfer activities within a certain period of time, second wireless network control node can start UE inactivity timer, if UE is before timer expiry, UE does not still have data transfer activities, then second wireless network control node can consider that UE business is over.Second of situation is that second wireless network control node, for example, RNC is received and come from the second wireless access standard core net node, for example, Serving GPRS Support Node（Serving GPRS Support Node, cylinder is referred to as " SGSN ") resource release message, then second wireless network control node can consider that UE business is over.

Thus, in embodiments of the present invention, alternatively, determination business of the user equipment when being migrated in the way of redirection to the network of the first wireless access standard proceeds, including：

When the user equipment is migrated in the way of redirecting to the network of the first wireless access standard, if the resource release message that the core net node for being not received by second wireless network control node is sent, and/or the inactivity timer of the user equipment is not timed-out, it is determined that the business of the user equipment proceeds.

Below in conjunction with Fig. 4 so that user equipment switches between LTE system and UMTS system as an example, the method that feedback information according to embodiments of the present invention is described in detail, wherein, the first wireless access standard Network is LTE network, and the network of the second wireless access standard is UMTS network, and the first wireless network control node is eNBl, and second wireless network controls node to be RNC.

In S310, eNBl initiates switching flow to RNC.Specifically, measurement configuration information can be sent to RNC by eNBl in the handoff requirement message sent to RNC, and the measurement configuration information can for example include the duration of frequency, threshold value and the UE measurements of measurement.The measurement configuration information can for example report the information of correlation with measurement result.So as to which RNC can determine that user equipment controls node RNC from the first wireless network control node eNBl successful switch to second wireless network;And receive the measurement configuration information of the first wireless network control node eNBl transmissions.

In S320, RNC sends measuring control information according to the measurement configuration information to UE, the measuring control information is used to indicate that cell progress of the UE to the first wireless access standard is signal quality measured, and the measuring control information is such as duration, report cycle that frequency, threshold value, the UE that can also include measurement are measured.

In S330, UE can be periodically to RNC report measurement results, and the measurement result can include the mark and the signal quality measurement result of the cell of the cell of measurement.

In S340, before the scheduled measurement duration that measurement configuration information is indicated terminates, RNC determines to migrate UE to the 3rd wireless network control node eNBx of the network of the first wireless access standard in the way of redirecting, 3rd wireless network control node controls node for the access network of the first wireless access standard, and the 3rd wireless network control node can be identical with the first wireless network control node, can also be different, that is eNBx can be eNBl, or other eNB.

In S350, before the scheduled measurement duration terminates, when UE is migrated in the way of redirecting to LTE network, RNC needs to be estimated the measurement result received, and determines that the signal quality that the cell of at least one the first wireless access standard whether is all indicated in the measurement result that RNC is received every time is more than threshold value.
