Description

A kind of network method for handover control, communication system and relevant device
Technical field
The present invention relates to the communications field, relate in particular to a kind of network method for handover control, communication system and relevant device.
Background technology
Along with the development of mobile communication technology, user's request more and more presents variation.In order to satisfy the diversified demand of user, the inside coverage base station of coverage base station and enterprise-level in the family room, and some other private network arises at the historic moment.For example Home eNodeB (HNB, Home NodeB), or title femtocells etc. have become present most potential low-cost access way.
In the prior art, subscriber equipment (UE, User Equipment) can switch to the HNB residential quarter from macrocell, and this switching mode is called Inbound Mobility to HNB, and handoff procedure roughly is:
When (1) UE detects the HNB residential quarter of satisfying switching condition, send measurement report to the source access network element, whether close subscriber group (CSG, the Closed Subscriber Group) sign and the UE that carry the HNB residential quarter in this measurement report are Member Users's indication information;
(2) the source access network element sends handover request message to core network element, comprises CSG sign and the access module of HNB residential quarter in this handover request message;
(3) core network element is according to the CSG sign of the HNB residential quarter in this handover request message and from attaching position register (HLR, Home Location Register) or home location server (HSS, Home Subscriber Server) the UE CSG CAMEL-Subscription-Information that obtains (also being the CSG identification list) carries out access control, if access control is passed through, then UE can switch to HNB.
Need to prove that core network element can get access to the CSG identification list from HLR or HSS by attachment flow or position update flow.
But, when UE has carried out striding after Public Land Mobile Network (PLMN, Public Land Mobile Network) switches, when in new PLMN residential quarter, switching to the HNB residential quarter, then may produce following situation:
If UE still carries out circuit switching (CS simultaneously after switching to new PLMN residential quarter, Circuit Switching) territory and packet switching (PS, Packet Switching) business in territory, UE finds that after receiving reallocation message PLMN and/or the band of position and/or Routing Area change, and more new technological process is initiated in preparation, this moment since CS territory business still carrying out, so with delay position new technological process more, this moment, MSC can't obtain UE CSG CAMEL-Subscription-Information under the new PLMN; And PS will obtain UE CSG CAMEL-Subscription-Information under the new PLMN after carrying out position update flow.
When in new PLMN residential quarter, switching to the HNB residential quarter, CS domain core net network element, (the MSC of mobile switching centre for example, Mobile Switching Center) and PS domain core net network element, serving general radio packet service support node (SGSN for example, Serving GPRS Support Node), can receive that the CSG that comprises the HNB residential quarter identifies and the handover request message of access module from access network element.
SGSN can get access to the CSG identification list of new PLMN, and because the carrying out of CS territory business, so that the position update flow of MSC is delayed, therefore MSC can't get access to by position update flow the CSG identification list of new PLMN from HLR or HSS, so SGSN carries out access control when receiving handover request message can be successful, and MSC when receiving handover request message, carry out access control can be failed.
SGSN access control success, then can send handover request message to HNB, HNB knows that this switching relates to CS territory and PS territory after receiving this handover request message, so can wait for the handover request message that MSC sends, but because failure of the access control of MSC, so HNB can't receive the handover request message that MSC sends all the time, behind self timer expiry, do not receive yet the feedback of HNB as SGSN, then can send switch failure information to access network element, thereby cause whole handoff procedure failure.
In the prior art scheme, after UE strides the PLMN switching, MSC can't get access to the CSG identification list of new PLMN, so MSC will inevitably be failed when carrying out access control, also will cause whole handoff procedure failure, so so that the hand off signaling that transmits between SGSN and the HNB becomes inactive signaling, thereby affected the system transmissions performance.

The embodiment of the invention can be in several ways switched network and is controlled, and the below describes respectively.
One, carry out the network switching controls by UE:
See also Fig. 1, embodiment of network method for handover control of the present invention can be as described below.
101, UE detects HNB;
In the present embodiment, UE can constantly detect near residential quarter along with the movement of position, and when UE moves to lower time of cell coverage area of HNB, UE then can detect this HNB.
102, UE judges that whether PLMN self occured to stride switches, and if not, then execution in step 103, if then execution in step 104.
UE detects after the HNB, if determine to satisfy switching condition, then UE can prepare to initiate the residential quarter switching, and UE can judge first that whether PLMN self occured to stride switches subsequently.
Need to prove, switching condition in the present embodiment can for: the signal strength signal intensity of current area drops to a certain threshold value, or the signal strength signal intensity of the residential quarter of HNB is higher than a certain threshold value etc., be understandable that, concrete switching condition is those skilled in the art's common practise, is not construed as limiting herein.
In the present embodiment, UE can determine in the following way that whether PLMN self occured to stride switches:
UE judges the PLMN from the reallocation message that the source access network element receives when switching, and/or the band of position (LA, Location Area), and/or Routing Area (RA, Routing Area) whether changes, if determine that then PLMN self occured to stride to be switched.
UE is with registration PLMN and/or registration LA and/or register RA relatively.
Do not find that conversion occurs for PLMN, LA and RA if UE receives in the reallocation message that the source access network element sends, illustrate that then PLMN self did not occur to stride to be switched.
Above-mentionedly only with an example UE in the present embodiment is determined self whether to occur to stride the mode that PLMN switches and be illustrated, be understandable that, in actual applications more mode can also be arranged, can in this locality a sign etc. be set when striding the PLMN switching such as UE, concrete mode is not construed as limiting herein at every turn.
103, carry out normal switching flow;
If UE determines that PLMN self did not occur to stride to be switched, then UE can carry out normal switching flow to switch to the residential quarter of HNB, and concrete handoff procedure is those skilled in the art's common practise, specifically is not construed as limiting herein.
104, judge whether still carrying out CS territory business, if then execution in step 105, if not, then execution in step 103;
Switch if UE determines self to occur to stride PLMN, then whether UE can further judge current still in that to carry out the CS territory professional.
Because when UE carried out the CS business, then the position update flow of Non-Access Stratum (NAS, Non-Access Straum) can be delayed, and carries out Shi Buhui in business and carries out, so UE can record this state.
When UE determined that PLMN self occured to stride to be switched, if find that position update flow still is in the state of being delayed, namely UE is current was still carrying out CS territory business.
Be understandable that UE judges whether still carrying out the business of CS territory except the sign with the position update flow of NAS, whether in actual applications, it is current still in that to carry out the CS territory professional to have other more methods to judge.
Need to prove that if UE determines that the current CS territory of not carrying out is professional, but carrying out PS territory business, then UE also can switch to according to existing switching flow the residential quarter of HNB.
CS territory business in the present embodiment is responsible for processing by CS domain core net network element, and PS territory business is responsible for processing by PS domain core net network element.
105, send measurement report to the source access network element.
In the present embodiment, switch if PLMN occurs to stride UE, and still carrying out CS territory business after switching, then UE can not switch to the residential quarter of HNB, produces a large amount of invalid signalings between PS domain core net network element and the HNB otherwise will cause.
Concrete, UE CSG member's indication information in the measurement report that reports the source access network element represents that UE is non-member, thus so that the source access network element can not initiated switching flow.
Wherein, this CSG member's indication information is in order to represent that UE is the Member Users, then when not carrying this CSG member's indication information in the measurement report, the source access network element can think that then UE is not the Member Users, also just naturally can not initiate switching flow, perhaps, this indication uses TRUE or FALSE to represent, TRUE represents it is the member, and FALSE represents non-member.
Source access network element in the present embodiment can be radio network controller (RNC, or base station controller (BSC, Base Station Controller) Radio Network Controller),, or evolution base station (eNB, evolved NodeB).
CS domain core net network element in the present embodiment can be MSC, and PS domain core net network element can be SGSN or MME (Mobility Management Entity, mobile management entity).
Be understandable that the source access network element in the present embodiment, CS domain core net network element and PS domain core net network element can also be other network elements, specifically are not construed as limiting herein.
In the present embodiment, UE detects after the HNB, if determine that PLMN self occured to stride to be switched, and still carrying out CS territory business after switching, then send measurement report to access network element, and CSG member's indication information represents that UE is non-member in the measurement report, then the source access network element just can not initiate to switch to core network element, then can effectively avoid the inactive signaling between PS domain core net network element and the HNB, thereby can improve the system transmissions performance.
Two, carry out the network switching controls by UE and the cooperation of source access network element:
The above has introduced the process that the UE side is carried out the network switching controls, and the below introduces another and cooperates the process of carrying out the network switching controls by source access network element and UE, sees also Fig. 2, and another embodiment of network method for handover control of the present invention can be as described below.
201, the source access network element receives the measurement report that UE sends;
In the present embodiment, UE is along with the movement of position, can constantly detect near residential quarter, when UE moves to lower time of cell coverage area of HNB, UE then can detect this HNB, and UE can send measurement report to the source access network element subsequently, then the source access network element can receive the measurement report that UE sends, comprise CSG sign and Member Users's indication in this measurement report, simultaneously, also comprise UE in this measurement report and carried out striding the indication that PLMN switches.
202, the source access network element obtains the type of service of the present ongoing business of UE;
The source access network element receives after the measurement report of UE transmission, carried out striding the indication that PLMN switches if find to comprise in this measurement report UE, then the source access network element can obtain the type of service of the present ongoing business of UE, concrete obtain manner can for:
Whether the indication that the source access network element connects by UE or reports when initiating business is perhaps by connecting to know the type of service of the present ongoing business of UE with the core net of same area not.
Be understandable that in actual applications, the source access network element can also be known by more mode the type of service of the present ongoing business of UE, specifically is not construed as limiting herein.
203, the source access network element is processed accordingly according to the type of service of the present ongoing business of UE.
After the source access network element gets access to the type of service of the present ongoing business of UE, then can process accordingly according to this type of service, concrete processing mode comprises:
(1) if UE is only carrying out CS territory business at present, then the source access network element does not initiate to switch to the flow process of HNB.
If UE is only carrying out CS territory business at present, because indicating UE in measurement report, UE carried out striding the PLMN switching, CS domain core net network element can't get access to the CSG identification list of new PLMN, so can cause handoff failure, therefore the source access network element can not initiate to switch to the flow process of HNB, for example can not initiate handover request message to core network element, thereby stop this HNB to switch.
(2) if UE carries out CS territory business and PS territory business at present just at the same time, then the source access network element can send the first handover request message to CS domain core net network element, and sends the second handover request message to PS domain core net network element.
If UE is carrying out CS territory business and PS territory business at present simultaneously, owing to only have the access control meeting failure of CS domain core net network element, so the source access network element carries different contents in the handover request message of CS domain core net network element and the transmission of PS domain core net network element, in issuing the first handover request message of CS domain core net network element, do not carry the CSG relevant information, carry the CSG relevant information and issue in the second handover request message of PS domain core net network element.
CSG relevant information in the present embodiment comprises CSG sign and the residential quarter access module of HNB.
Because the source access network element does not carry the CSG relevant information in the first handover request message of CS domain core net network element transmission, so CS domain core net network element just can not carry out access control, just can not cause handoff failure yet.
(3) if UE is only carrying out PS territory business at present, then the source access network element sends handover request message according to existing switching flow to PS domain core net network element.
If UE is only carrying out PS territory business at present, because PS domain core net network element can get access to the CSG identification list of new PLMN, so the source access network element can send handover request message to PS domain core net network element according to existing switching flow, and carries out follow-up switching flow.
Need to prove that the source access network element in the present embodiment can be RNC, or BSC, or eNB.
CS domain core net network element in the present embodiment can be MSC, and PS domain core net network element can be SGSN or MME.
Be understandable that the source access network element in the present embodiment, CS domain core net network element and PS domain core net network element can also be other network elements, specifically are not construed as limiting herein.
In the present embodiment, when the source access network element knows that from measurement report UE has carried out striding the PLMN switching, if UE is only carrying out CS territory business at present, then the source access network element can not initiate to switch to the flow process of HNB, for example do not initiate handover request message to core network element, then can effectively avoid the inactive signaling between PS domain core net network element and the HNB, thereby can improve the system transmissions performance;
When the source access network element knows that from measurement report UE has carried out striding the PLMN switching, if UE is carrying out CS territory business and PS territory business at present simultaneously, then the source access network element does not carry the CSG relevant information in issuing the first handover request message of CS domain core net network element, this CSG relevant information comprises CSG sign and the residential quarter access module of HNB, CS domain core net network element does not receive the CSG relevant information from the source access network element, so just can not carry out access control, just can not cause handoff failure yet, also can effectively avoid the inactive signaling between PS domain core net network element and the HNB, thereby can improve the system transmissions performance.
The above is described the network method for handover control the present embodiment from the angle of source access network element, the below is described the network method for handover control the present embodiment from the angle of UE, see also Fig. 3, another embodiment of network method for handover control of the present invention can be as described below.
301, UE detects HNB;
In the present embodiment, UE can constantly detect near residential quarter along with the movement of position, and when UE moves to lower time of cell coverage area of HNB, UE then can detect this HNB.
302, UE judges that whether PLMN self occured to stride switches, and if not, then execution in step 303, if then execution in step 304;
UE detects after the HNB, if determine to satisfy switching condition, then UE can prepare to initiate the residential quarter switching, and UE can judge first that whether PLMN self occured to stride switches subsequently.
Need to prove, switching condition in the present embodiment can for: the signal strength signal intensity of current area drops to a certain threshold value, or the signal strength signal intensity of the residential quarter of HNB is higher than a certain threshold value etc., be understandable that, concrete switching condition is those skilled in the art's common practise, is not construed as limiting herein.
In the present embodiment, UE can determine in the following way that whether PLMN self occured to stride switches:
UE judges the PLMN from the reallocation message that the source access network element receives when switching, and/or LA, and/or whether RA change, if then determine self to occur to stride the PLMN switching.
Do not find that conversion occurs for PLMN, LA and RA if UE receives in the reallocation message that the source access network element sends, illustrate that then PLMN self did not occur to stride to be switched.
Above-mentionedly only with an example UE in the present embodiment is determined self whether to occur to stride the mode that PLMN switches and be illustrated, be understandable that, in actual applications more mode can also be arranged, can in this locality a sign etc. be set when striding the PLMN switching such as UE, concrete mode is not construed as limiting herein at every turn.
303, carry out normal switching flow;
If UE determines that PLMN self did not occur to stride to be switched, then UE can carry out normal switching flow to switch to the residential quarter of HNB, and concrete handoff procedure is those skilled in the art's common practise, specifically is not construed as limiting herein.
304, send measurement report to the source access network element, carry UE in this measurement report and carried out striding the indication that PLMN switches.
If UE determines that PLMN self occured to stride to be switched, then when the source access network element sends measurement report, can carry UE and carry out striding the indication that PLMN switches, this indication can increase a cell newly in measurement report, for example PLMN handover indicator is in order to expression, the expression mode can for: if carry this cell, represent that then UE has carried out striding PLMN and switched, if do not carry this cell, represent that then UE does not stride PLMN and switches, perhaps, if the value of this cell is 1, represent that then UE has carried out striding PLMN and switched, if the value of this cell is 0, represent that then UE does not stride PLMN and switches.
Be understandable that in actual applications, UE can also carry UE with more mode and carry out striding the indication that PLMN switches in the measurement report of issuing the source access network element, concrete mode is not construed as limiting herein.
In the present embodiment, UE is after confirming that having carried out striding PLMN switches, can in the measurement report of issuing the source access network element, carry UE and carry out striding the indication that PLMN switches, so that the source access network element can carry out follow-up network switching controls according to this indication, avoiding the inactive signaling between PS domain core net network element and the HNB, thereby can improve the system transmissions performance.
For ease of understanding, the below is described the network method for handover control in the present embodiment with a concrete application scenarios, sees also Fig. 4, and another embodiment of network method for handover control of the present invention can be as described below.
401, UE sends measurement report to source RNC;
In the present embodiment, UE can constantly detect near residential quarter along with the movement of position, and when UE moves to lower time of cell coverage area of HNB, UE then can detect this HNB.
If determine to satisfy switching condition, then UE can prepare to initiate the residential quarter switching, and UE can judge first that whether PLMN self occured to stride switches subsequently.
Need to prove, switching condition in the present embodiment can for: the signal strength signal intensity of current area drops to a certain threshold value, or the signal strength signal intensity of the residential quarter of HNB is higher than a certain threshold value etc., be understandable that, concrete switching condition is those skilled in the art's common practise, is not construed as limiting herein.
In the present embodiment, UE can determine in the following way that whether PLMN self occured to stride switches:
UE judges the PLMN from the reallocation message that the source access network element receives when switching, and/or LA, and/or whether RA change, if then determine self to occur to stride the PLMN switching.
Do not find that conversion occurs for PLMN, LA and RA if UE receives in the reallocation message that the source access network element sends, illustrate that then PLMN self did not occur to stride to be switched.
Above-mentionedly only with an example UE in the present embodiment is determined self whether to occur to stride the mode that PLMN switches and be illustrated, be understandable that, in actual applications more mode can also be arranged, can in this locality a sign etc. be set when striding the PLMN switching such as UE, concrete mode is not construed as limiting herein at every turn.
For follow-up description, the below carries out briefly bright to the process of striding the PLMN switching first:
Suppose that UE is originally in the PLMN-A network, CS domain core net network element in the PLMN-A network is MSC-A, PS domain core net network element is SGSN-A, access network element is RNC-A, after UE moved in the PLMN-B network, then UE communicated in the PLMN-B network, and the CS domain core net network element in the PLMN-B network is MSC-B, PS domain core net network element is SGSN-B, and access network element is RNC-B.
For the CS territory, Serving RNC becomes RNC-B, and RNC-B is connected to MSC-B, although the PLMN difference of at this moment new residential quarter, but UE can launch position new technological process more, the constant MSC-A that is still of MSC anchor point, the transmittance process of signaling is: RNC-B=＞MSC-B=＞MSC-A.
If UE determines that PLMN self occured to stride to be switched, then when source RNC sends measurement report, can carry UE and carry out striding the indication that PLMN switches, this indication can increase a cell newly in measurement report, for example PLMN handover indicator is in order to expression, the expression mode can for: if carry this cell, represent that then UE has carried out striding PLMN and switched, if do not carry this cell, represent that then UE does not stride PLMN and switches, perhaps, if the value of this cell is 1, represent that then UE has carried out striding PLMN and switched, if the value of this cell is 0, represent that then UE does not stride PLMN and switches.
Be understandable that in actual applications, UE can also carry UE with more mode and carry out striding the indication that PLMN switches in the measurement report of issuing source RNC, concrete mode is not construed as limiting herein.
In the present embodiment, describe as the example of source access network element with RNC, be understandable that, in actual applications, this source access network element can also be BSC, or eNB etc., specifically be not construed as limiting herein.
In the present embodiment, with the example of MSC as CS domain core net network element, with the example of SGSN as PS domain core net network element, be understandable that, in actual applications, this CS domain core net network element and PS domain core net network element can also be the network elements of other types, specifically are not construed as limiting herein.
402～403, RNC sends handover request message;
In the present embodiment, source RNC receives after the measurement report of UE transmission, has striden the indication that PLMN switches if find to carry in this measurement report UE, and then source RNC can obtain the type of service of the current ongoing business of UE.
If source RNC determines UE and is only carrying out CS territory business at present that then source RNC can not initiate to switch to the flow process of HNB, for example can not initiate handover request message to core network element, thereby stops this HNB to switch, then this flow process end.
If source RNC determines UE and carries out just at the same time at present CS territory business and PS territory business, then source RNC can send handover request message to SGSN-B and MSC-B, but the content that sends is different, wherein, issue the CSG sign and the access module that carry HNB in the handover request message of SGSN-B, issue the CSG sign and the access module that then do not carry HNB in the handover request message of MSC-B.
404, the SGSN-B access control is passed through;
Because SGSN-B can get access to the CSG identification list of UE in the PLMN-B network, can get access to from source RNC again CSG sign and the access module of HNB, then SGSN-B can judge HNB CSG sign whether in the CSG identification list, if, then access control is passed through.
405, SGSN-B sends handover request message by the HNB gateway to HNB;
After the SGSN-B access is passed through, can send handover request message to HNB by the HNB gateway, carry the CSG sign of HNB in this handover request message, carry out the residential quarter with request and switch.
Be understandable that in actual applications, SGSN-B can directly send handover request message to the HNB gateway, also can send handover request message to the HNB gateway by other core network element, specifically be not construed as limiting herein.
406, MSC-B sends handover request message by the HNB gateway to HNB;
MSC-B receives after the handover request message from source RNC, this handover request message can be forwarded to MSC-A, MSC-A determines not carry in this handover request message CSG sign and the access module of HNB, then do not carry out access control, carry out the residential quarter switching and can directly send handover request message by the HNB gateway to HNB with request, do not carry the CSG sign of HNB in this handover request message.
Be understandable that in actual applications, MSC-A can directly send handover request message to the HNB gateway, also can be by other core network element, for example MSC-B sends handover request message to the HNB gateway, specifically is not construed as limiting herein.
407～408, HNB receives after the handover request message of SGSN-B and MSC-B transmission, replys respectively switch acknowledgment message by the HNB gateway.
409～410, SGSN-B and MSC-B receive and send switching command message to source RNC respectively after the switch acknowledgment message of HNB answer, switch to carry out.
In the present embodiment, when source RNC knows that from measurement report UE has carried out striding the PLMN switching, if UE is carrying out CS territory business and PS territory business at present simultaneously, then source RNC does not carry the CSG relevant information in issuing the first handover request message of MSC-B, this CSG relevant information comprises CSG sign and the residential quarter access module of HNB, MSC-B does not receive the CSG relevant information from the source access network element, so just can not carry out access control, just can not cause handoff failure yet, also can effectively avoid the inactive signaling between SGSN-B and the HNB, thereby can improve the system transmissions performance.
Three, cooperated with CS domain core net network element by the source access network element and carry out the network switching controls:
The above has introduced the UE side and UE cooperates the process of carrying out the network switching controls with the source access network element, the below introduces another and cooperates the process of carrying out the network switching controls by source access network element and CS domain core net network element, see also Fig. 5, another embodiment of network method for handover control of the present invention can be as described below.
501, the source access network element receives the measurement report that UE sends;
In the present embodiment, UE is along with the movement of position, can constantly detect near residential quarter, when UE moves to lower time of cell coverage area of HNB, UE then can detect this HNB, UE can send measurement report to the source access network element subsequently, and then the source access network element can receive the measurement report that UE sends, and comprises CSG sign and Member Users's indication in this measurement report.
502, the source access network element obtains the type of service of the present ongoing business of UE;
The source access network element receives after the measurement report that UE sends, and then the source access network element can obtain the type of service of the present ongoing business of UE, concrete obtain manner can for:
Whether the indication that the source access network element connects by UE or reports when initiating business is perhaps by connecting to know the type of service of the present ongoing business of UE with the core net of same area not.
Be understandable that in actual applications, the source access network element can also be known by more mode the type of service of the present ongoing business of UE, specifically is not construed as limiting herein.
If it is professional that 503 UE carry out CS territory business and PS territory at present just at the same time, then the source access network element sends handover request message to CS domain core net network element, comprises the indication information that this switching relates to a plurality of core network domain in this handover request message.
If the source access network element is determined UE and carries out just at the same time at present CS territory business and PS territory business that then the source access network element can send handover request message to CS domain core net network element, comprise the indication that this switching relates to a plurality of core network domain in this handover request message.
This indication can increase a cell newly in handover request message, for example MultiCN handover indicator is in order to expression, the expression mode can for: if carry this cell, represent that then this switching relates to a plurality of core network domain, if do not carry this cell, represent that then this switching does not relate to a plurality of core network domain, perhaps, if the value of this cell is 1, represent that then this switching relates to a plurality of core network domain, if the value of this cell is 0, represent that then this switching does not relate to a plurality of core network domain.
Be understandable that in actual applications, the source access network element can also carry the indication that this switching relates to a plurality of core network domain with more mode in the handover request message of issuing CS domain core net network element, concrete mode is not construed as limiting herein.
Need to prove that the source access network element in the present embodiment can be RNC, or BSC, or eNB.
CS domain core net network element in the present embodiment can be MSC, and PS domain core net network element can be SGSN or MME.
In the present embodiment, the source access network element determines that UE is carrying out after CS territory business and the PS territory business at present, can send handover request message to CS domain core net network element, comprise the indication that this switching relates to a plurality of core network domain in this handover request message, so that CS domain core net network element knows that this switching relates to a plurality of core network domain, so can carry out corresponding network switching controls, avoiding the inactive signaling between SGSN-B and the HNB, thereby can improve the system transmissions performance.
The above is illustrated network method for handover control of the present invention from the angle of source access network element, the below describes network method for handover control of the present invention from the angle of CS domain core net network element, see also Fig. 6, another embodiment of network method for handover control of the present invention can be as described below.
601, a CS domain core net network element receives the handover request message from the source access network element;
After the source access network element sent handover request message, a CS domain core net network element can receive this handover request message.
602, judge whether this handover request message is transmitted by the 2nd CS domain core net network element, if then execution in step 604, if not, then execution in step 603;
After a CS domain core net network element receives handover request message, if determine to comprise the indication information that this switching relates to a plurality of core network domain in this handover request message, can judge then whether this handover request message is transmitted by the 2nd CS domain core net network element.
In the present embodiment, a CS domain core net network element and the 2nd CS domain core net network element belong to respectively different PLMN.
603, carry out normal switching flow;
If it is not to be transmitted by the 2nd CS domain core net network element that a CS domain core net network element is determined this handover request message, illustrate that then this handover request message is directly to send to a CS domain core net network element by source RNC, that is to say that UE does not stride PLMN and switches, then a CS domain core net network element can be carried out normal switching flow to switch to the residential quarter of HNB, and detailed process is not construed as limiting herein.
604, a CS domain core net network element does not carry out access control, and sends handover request message to Home eNodeB HNB;
If it is to be transmitted by the 2nd CS domain core net network element that belongs to different PLMN that a CS domain core net network element is determined this handover request message, illustrate that then UE PLMN has occured to stride switched, this handover request message is to be transmitted by the 2nd CS domain core net network element of new PLMN.
Because a CS domain core net network element can't get access to the CSG identification list of new PLMN, so if carry out access control, then inevitable failure so a CS domain core net network element does not carry out access control, and directly sends handover request message to HNB.
605, a CS domain core net network element receives the switch acknowledgment message of HNB feedback, and sends switching command message to the source access network element.
The one CS domain core net network element can receive switch acknowledgment message from HNB after having sent handover request message to HNB, a CS domain core net network element can send switching command message to carry out switching to the source access network element subsequently.
Need to prove that the source access network element in the present embodiment can be RNC, or BSC, or eNB.
CS domain core net network element in the present embodiment can be MSC, and PS domain core net network element can be SGSN.
In the present embodiment, the one CS domain core net network element receives after the handover request message, comprise the indication that this switching relates to a plurality of core network domain if determine in this handover request message, can judge that then whether this handover request message is by the 2nd CS domain core net network element that belongs to another PLMN, if, illustrate that then UE PLMN has occured to stride switched, because a CS domain core net network element can't get access to the CSG identification list of new PLMN, if so carry out access control, then inevitable failure, so a CS domain core net network element does not carry out access control, and directly send handover request message to HNB, avoiding the inactive signaling between SGSN-B and the HNB, thereby can improve the system transmissions performance.
Four, carry out the network switching controls by the HNB side:
The above has introduced the UE side and has carried out network switching controls, UE and cooperate with the source access network element and carry out the network switching controls and the source access network element cooperates the process of carrying out the network switching controls with CS domain core net network element, the below introduces another process of independently being carried out the network switching controls by the HNB side, see also Fig. 7, another embodiment of network method for handover control of the present invention can be as described below.
701, HNB receives the handover request message that PS domain core net network element sends;
When needs were initiated the HNB switching, HNB can receive handover request message from PS domain core net network element, carried the CSG sign of HNB in this handover request message.
Relate to simultaneously PS territory and CS territory if 702 handover request message indicate this to switch, then HNB starts the feedback timer;
If HNB identifies this switching and relates to simultaneously PS territory and CS territory receiving from PS domain core net network element the handover request message, and HNB not yet receives the handover request message that CS domain core net network element sends, then HNB starts the feedback timer.
If 703 before the feedback timer expiry, HNB does not receive the handover request message that CS domain core net network element sends yet, and then HNB is to PS domain core net network element feedback switch acknowledgment message.
HNB starts after the feedback timer, if before this feedback timer expiry, HNB does not receive the handover request message that CS domain core net network element sends yet, and then HNB is to PS domain core net network element feedback switch acknowledgment message, so that PS domain core net network element is proceeded follow-up handover operation.
Need to prove, in the present embodiment, the overtime duration of the feedback timer of HNB is shorter than the overtime duration of the handoff failure timer of PS domain core net network element, that is to say, PS domain core net network element can be received switch acknowledgment message from HNB before the switching overtime failure.
Need to prove that the source access network element in the present embodiment can be RNC, or BSC, or eNB.
CS domain core net network element in the present embodiment can be MSC, and PS domain core net network element can be SGSN or MME.
For ease of understanding, the below is described the network method for handover control in the present embodiment with a concrete application scenarios, sees also Fig. 8, and another embodiment of network method for handover control of the present invention can be as described below.
801, UE sends measurement report to source RNC;
In the present embodiment, UE can constantly detect near residential quarter along with the movement of position, and when UE moves to lower time of cell coverage area of HNB, UE then can detect this HNB.
If determine to satisfy switching condition, then UE can prepare to initiate the residential quarter switching, and then UE can send measurement report to source RNC, comprise the CSG sign of HNB and member's indication information of UE in this measurement report.
In the present embodiment, describe as the example of source access network element with RNC, be understandable that, in actual applications, this source access network element can also be BSC, or eNB etc., specifically be not construed as limiting herein.
In the present embodiment, with the example of MSC as CS domain core net network element, with the example of SGSN as PS domain core net network element, be understandable that, in actual applications, this CS domain core net network element and PS domain core net network element can also be the network elements of other types, specifically are not construed as limiting herein.
802～803, RNC sends handover request message;
In the present embodiment, source RNC receives after the measurement report of UE transmission, can send handover request message to SGSN-B and MSC-B, and the content of transmission is identical, includes CSG sign and the access module of HNB.
804, access control is passed through;
Because SGSN-B can get access to the CSG identification list of UE in the PLMN-B network, can get access to from source RNC again CSG sign and the access module of HNB, then SGSN-B can judge HNB CSG sign whether in the CSG identification list, if, then access control is passed through.
805, access control failure;
Because MSC-A can't get access to the CSG identification list of UE in the PLMN-B network, so when the CSG sign that gets access to HNB from source RNC and access module, the access control meeting failure of MSC-A then can not send handover request message to HNB again.
806, SGSN-B sends handover request message by the HNB gateway to HNB;
After the SGSN-B access is passed through, can send handover request message to HNB by the HNB gateway, carry the CSG sign of HNB in this handover request message, carry out the residential quarter with request and switch.
807, HNB starts the feedback timer;
HNB identifies this switching and relates to simultaneously PS territory and CS territory receiving from PS domain core net network element the handover request message, and HNB not yet receives the handover request message that MSC sends, and then HNB starts the feedback timer.
808, feedback timer expiry;
809, HNB sends switch acknowledgment message by the HNB gateway to SGSN-B;
If before the feedback timer expiry, HNB does not receive the handover request message that MSC sends yet, then HNB feeds back switch acknowledgment message to SGSN-B, so that SGSN-B proceeds follow-up handover operation.
Need to prove that in the present embodiment, the overtime duration of the feedback timer of HNB is shorter than the overtime duration of the handoff failure timer of SGSN-B, that is to say that SGSN-B can receive switch acknowledgment message from HNB before the switching overtime failure.
810, SGSN-B receives and sends switching command message to source RNC after the switch acknowledgment message of HNB answer, switches to carry out.
In the present embodiment, HNB identifies this and switches when relating to simultaneously PS territory and CS territory receiving from PS domain core net network element the handover request message, if HNB not yet receives the handover request message that CS domain core net network element sends, then HNB starts the feedback timer, if before this feedback timer expiry, HNB does not receive the handover request message that CS domain core net network element sends yet, then HNB is to PS domain core net network element feedback switch acknowledgment message, so that PS domain core net network element is proceeded follow-up handover operation, because the overtime duration of this feedback timer is shorter than the overtime duration of the handoff failure timer of PS domain core net network element, so, PS domain core net network element can be received switch acknowledgment message from HNB before the switching overtime failure, so can avoid the inactive signaling between PS domain core net network element and the HNB, thereby can improve the system transmissions performance.
The below introduces the device item in the embodiment of the invention, sees also Fig. 9, and embodiment of subscriber equipment of the present invention can be as described below.
The first detecting unit 901 is for detection of HNB;
The first switching judging unit 902 is used for after detecting unit 901 detects HNB, judges that whether PLMN self occured to stride switches;
The first transmitting element 904 is used for determining that when the first switching judging unit 902 PLMN occured to stride to be switched, and subscriber equipment is still when carrying out CS territory business, and to source access network element transmission measurement report, CSG member's indication information represents that UE is non-member in this measurement report.
Subscriber equipment in the present embodiment can further include:
Business judging unit 903 is used for when the PLMN switching is determined to occur in the first switching judging unit 902, judges and whether is still carrying out CS territory business after PLMN occurs self to be switched.
For ease of understanding, the below describes with the contact of an instantiation to each unit in the present embodiment subscriber equipment:
In the present embodiment, UE is along with the movement of position, and the first detecting unit 901 can constantly detect near residential quarter, and when UE moves to lower time of cell coverage area of HNB, 901 of the first detecting units can detect this HNB.
The first detecting unit 901 detects after the HNB, if determine to satisfy switching condition, then UE can prepare to initiate the residential quarter switching, and the first switching judging unit 902 can judge first that whether PLMN self occured to stride switches subsequently.
Need to prove, switching condition in the present embodiment can for: the signal strength signal intensity of current area drops to a certain threshold value, or the signal strength signal intensity of the residential quarter of HNB is higher than a certain threshold value etc., be understandable that, concrete switching condition is those skilled in the art's common practise, is not construed as limiting herein.
In the present embodiment, the first switching judging unit 902 determines that whether UE mode that PLMN switches and the described content class of aforementioned middle step 102 embodiment illustrated in fig. 1 occured to stride seemingly, repeated no more herein.
If the first switching judging unit 902 determines that UE PLMN did not occur to stride switches, then UE can carry out normal switching flow to switch to the residential quarter of HNB, and concrete handoff procedure is those skilled in the art's common practise, specifically is not construed as limiting herein.
If the first switching judging unit 902 determines UE the PLMN switching occured to stride, then professional judging unit 903 can further judge currently whether still carrying out CS territory business.
In the present embodiment, switch if PLMN occurs to stride UE, and still carrying out CS territory business after switching, then UE can not switch to the residential quarter of HNB, produces a large amount of invalid signalings between PS domain core net network element and the HNB otherwise will cause.
Concrete, the first transmitting element 904 CSG member's indication information in the measurement report that reports the source access network element represents that UE is non-member, thus so that the source access network element can not initiated switching flow.
Wherein, this CSG member's indication information is in order to represent that UE is the Member Users, and then when not carrying this CSG member's indication information in the measurement report, the source access network element can think that then UE is not the Member Users, also just naturally can not initiate switching flow.Perhaps, this indication uses TRUE or FALSE to represent TRUE represents it is the member, and FALSE represents non-member.
In the present embodiment, the first detecting unit 901 detects after the HNB, if the first switching judging unit 902 determines that UE PLMN occured to stride switches, and after determining to switch, professional judging unit 903 still carrying out CS territory business, then the first transmitting element 904 sends measurement report to access network element, and CSG member's indication information represents that UE is non-member in the measurement report, then the source access network element just can not initiate to switch to CS domain core net network element, then can effectively avoid the inactive signaling between PS domain core net network element and the HNB, thereby can improve the system transmissions performance.
See also Figure 10, embodiment of access network element of the present invention can be as described below.
The first receiving element 1001 be used for to receive the measurement report that user equipment (UE) sends, and comprises this UE in this measurement report and has carried out Public Land Mobile Network and stride the indication that PLMN switches;
The first acquiring unit 1002 is for the type of service of obtaining the present ongoing business of this UE;
The first processing unit 1003 is used for determining that when this first acquiring unit 1002 these UE at present only when carrying out circuit switching (CS) territory business, do not initiate to switch to the flow process of HNB; Or, when this first acquiring unit 1002 determines that this UE carries out CS territory business and packet switching PS territory business at present just at the same time, send the first handover request message to CS domain core net network element, and send the second handover request message to PS domain core net network element, do not carry close subscriber group CSG relevant information in this first handover request message, carry the CSG relevant information in this second handover request message.
CSG relevant information in the present embodiment comprises CSG sign and the residential quarter access module of HNB.
For ease of understanding, the below describes with the contact of an instantiation to each unit in the present embodiment access network element:
In the present embodiment, UE is along with the movement of position, can constantly detect near residential quarter, when UE moves to lower time of cell coverage area of HNB, UE then can detect this HNB, and UE can send measurement report to the source access network element subsequently, then the first receiving element 1001 can receive the measurement report that UE sends, comprise CSG sign and Member Users's indication in this measurement report, simultaneously, also comprise UE in this measurement report and carried out striding the indication that PLMN switches.
The first receiving element 1001 receives after the measurement report of UE transmission, carried out striding the indication that PLMN switches if find to comprise in this measurement report UE, then the first acquiring unit 1002 can obtain the type of service of the present ongoing business of UE, concrete obtain manner can for:
Whether the indication that the source access network element connects by UE or reports when initiating business is perhaps by connecting to know the type of service of the present ongoing business of UE with the core net of same area not.
Be understandable that in actual applications, the source access network element can also be known by more mode the type of service of the present ongoing business of UE, specifically is not construed as limiting herein.
After the first acquiring unit 1002 got access to the type of service of the present ongoing business of UE, then the first processing unit 1003 can be processed accordingly according to this type of service, and concrete processing mode comprises:
(1) if UE is only carrying out CS territory business at present, then the first processing unit 1003 does not initiate to switch to the flow process of HNB.
If UE is only carrying out CS territory business at present, because indicating UE in measurement report, UE carried out striding the PLMN switching, CS domain core net network element can't get access to the CSG identification list of new PLMN, so can cause handoff failure, therefore the first processing unit 1003 can not initiate to switch to the flow process of HNB, for example can not initiate handover request message to core network element, thereby stop this HNB to switch.
(2) if UE carries out CS territory business and PS territory business at present just at the same time, then the first processing unit 1003 can send the first handover request message to CS domain core net network element, and sends the second handover request message to PS domain core net network element.
