The switching type control method of base station from home of the present invention as shown in Figure 3, comprising:
Step 301 is first base station and the second base station configuration switchover policy.
Wherein, when first base station was target BS, second base station was a serving BS; When first base station was serving BS, second base station was a target BS;
Serving BS provides serving base station for current for portable terminal; Target BS is the base station that portable terminal will be cut.
The type information of first base station or second base station comprises: base station from home and macro base station.
Before portable terminal was carried out handover operation, at each base station from home, operator all can control relevant strategy with switching type for it customizes one group, abbreviates switchover policy as, preferably, can represent this strategy with the form of bitmap, is specially:
As required, a 0x00 can be set express support for/do not support portable terminal and switch to base station from home (at this moment, this base station from home is as target BS) from common macro base station; A 0x01 is set expresses support for/do not support portable terminal and switch to macro base station (at this moment, this base station from home is as serving BS) from base station from home; A 0x02 is set expresses support for/do not support portable terminal and between current base station from home and another one base station from home, switch (at this moment, current base station from home promptly also can be used as target BS as serving BS).
Perhaps, the definition of rheme 0x00 and position 0x01 in the reservation, increase a position 0x02, position 0x03 definition: a 0x02 is set expresses support for/do not support portable terminal and switch to another one base station from home (at this moment, current base station from home is as serving BS) from current base station from home; A 0x03 is set expresses support for/do not support portable terminal and switch to current base station from home (at this moment, current base station from home is as target BS) from another base station from home.
After finishing the customization of switchover policy, need this strategy be sent in the switching control function of base station from home by network side entity: preferably, carry out initialization in the family expenses base station and power in the networking process, strategy is sent to base station from home by the configuration server of network side or policy control server or network management system; Certainly, also can after family expenses base station access network is as base station work, by above-mentioned network side entity strategy be sent to base station from home again.
Based on the corresponding strategies of above-mentioned switching type control, the switching type controlling schemes of base station from home of the present invention is described below by specific embodiment.
Figure 4 shows that the schematic flow sheet of the present invention, comprising with the switching type control method embodiment one of base station:
Step 401, portable terminal sends the request of moving to serving BS.
Portable terminal has inserted in the mobile communications network, and prepares to carry out handover operation; In handoff preparation phase, portable terminal to current be that the serving BS of its service is initiated handoff request, handoff request is the request of moving among this embodiment, carries the candidate target base station that one group of portable terminal is selected in the request.
Usually, portable terminal can be determined one group of above-mentioned candidate target base station by measuring modes such as peripheral wireless signal strength and quality.Can comprise one or more common macro base station and base station from home simultaneously in this group candidate target base station.Preferably, the form of this group candidate target base station with tabulation is carried in the request of moving, storage can be the unique identification of each candidate target base station in this tabulation.
Step 402, serving BS all sends one to each candidate target base station and prepares handoff request, carries the sign of anchor point authentication device of portable terminal and the sign of anchor point IAD in this request.
Preparing handoff request also needs to carry the type information of this serving BS, and the type information can represent that serving BS is a macro base station or a base station from home.For example, operation parameter BS_TYPE=0 represents macro base station; Operation parameter BS_TYPE=1 represents base station from home.
Usually, if serving BS can't directly send to candidate target base station with preparing handoff request, so, serving BS can send to this preparation handoff request earlier on the relaying IAD, will prepare handoff request by this relaying IAD again and be forwarded on the candidate target base station.
Step 403, candidate target base station receive to be prepared to read the type information of the serving BS that carries in this request after the handoff request, and carries out switching type control according to the type of serving BS.
At first, if current candidate target base station is a macro base station, then switching type control can not carried out, directly redirect execution in step 404;
If current candidate target base station is a base station from home, then this base station from home need be carried out switching type control.Concrete candidate target base station need determine how to carry out switching type control according to the type of serving BS:
Candidate target base station is according to the switchover policy of self, if the strategy current candidate target base station of regulation (base station from home) does not support portable terminal to switch on the base station from home from macro base station, then, type information according to serving BS, if serving BS is a macro base station, then current candidate target base station does not support portable terminal to carry out the switching of current type, be that portable terminal is the switching of the serving BS of macro base station to self from type, at this moment, this candidate target base station will be refused above-mentioned preparation handoff request in view of the above, jump to step 406, return the preparation switching request response of failure to serving BS, an indication is carried in this response, is used to inform that this candidate target base station of serving BS (base station from home) do not support the switching of this type; If serving BS is not a macro base station, then current candidate target base station supports portable terminal to carry out the switching of current type;
If the strategy current candidate target base station of regulation (base station from home) does not support portable terminal to switch on the base station from home from base station from home, then, type information according to serving BS, if serving BS is a base station from home, then current candidate target base station does not support portable terminal to carry out the switching of current type, at this moment, this candidate target base station will be refused above-mentioned preparation handoff request in view of the above, jump to step 406, return the preparation switching request response of failure to serving BS, an indication is carried in this response, is used to inform that this candidate target base station of serving BS (base station from home) do not support the switching of this type; If serving BS is not a base station from home, then current candidate target base station supports portable terminal to carry out the switching of current type.
Otherwise, if stipulating current candidate target base station, switchover policy supports that portable terminal switches to base station from home from serving BS (macro base station or base station from home), then current candidate target base station supports portable terminal to carry out the switching of current type.
It is pointed out that if candidate target base station is a macro base station, then give tacit consent to it and support portable terminal to carry out the switching of current type.
Step 404, the anchor point authentication device of candidate target base station and portable terminal is by context information request and response message, the contextual information of this portable terminal alternately.
Wherein, candidate target base station can find the anchor point authentication device of portable terminal correspondence by the sign of preparing the anchor point authentication device in the handoff request.The mutual of the contextual information of portable terminal is prior art in this step, repeats no more herein.
To carry out data channel pre-established for this portable terminal between the anchor point IAD of self and portable terminal for step 405, candidate target base station.
Wherein, candidate target base station can find corresponding anchor point IAD by the sign of preparing anchor point IAD in the handoff request.Data channel is pre-established to be initiated by candidate target base station, this step be embodied as prior art, repeat no more herein.
Step 406, candidate target base station is returned the preparation switching request response to serving BS, and this response has indicated this candidate target base station whether to accept the handoff request of portable terminal.
From step 403 as can be known, when candidate target base station (base station from home) is not supported the switching of current type, just carry an indication, do not accept the reason of the handoff request of portable terminal to inform this candidate target base station of serving BS: do not support the switching of current type by the preparation switching request response of failure.
When candidate target base station is not accepted the handoff request of portable terminal, also have a kind of situation: candidate target base station (macro base station or base station from home) is when supporting the switching of current type, need also to judge the handoff request of whether accepting portable terminal that whether effectively and the pre-established whether success of above-mentioned data channel or the like the contextual information that whether the mutual portable terminal of enough resources and anchor point authentication device is arranged as: current candidate target base station according to default precondition.Operation strategy according to reality, if candidate target base station only satisfies switching type of the present invention, and do not satisfy in above-mentioned other conditions any one, then candidate target base station also can not be accepted the handoff request of portable terminal, at this moment, candidate target base station is carried an indication by the preparation switching request response of failure, is used to inform that the current candidate target base station of serving BS do not accept the reason of the handoff request of portable terminal.
Have only when satisfying switching type of the present invention and above-mentioned other preconditions simultaneously, this candidate target base station is just understood the handoff request of receiving terminal.At this moment, candidate target base station sends successful preparation switching request response to serving BS, wherein needs to carry the type information of current candidate target base station, can adopt the described parameter mode of step 402 to represent the type information of base station.
After step 407, serving BS receive and prepare switching request response, read the type information of candidate target base station, and carry out switching type control according to the type of candidate target base station.
If serving BS is a macro base station, then this serving BS can not carried out switching type control, directly redirect execution in step 408;
If serving BS is a base station from home, then this serving BS need be carried out switching type control.Concrete, serving BS is according to the type of candidate target base station, and how decision carries out switching type control:
Serving BS is according to the switchover policy of self, if strategy is stipulated this serving BS (base station from home) and is not supported that portable terminal switches to macro base station, then, type information according to candidate target base station, if candidate target base station is a macro base station, then this serving BS as not changeable target BS, does not promptly support portable terminal to carry out the switching of current type (from Current Serving BTS, be that base station from home switches to macro base station) this candidate target base station; If candidate target base station is not a macro base station, then this serving BS as switchable target BS, is promptly supported the switching of current type with this candidate target base station;
If strategy is stipulated this serving BS (base station from home) and is not supported that portable terminal switches to base station from home, then, type information according to candidate target base station, if candidate target base station is a base station from home, then this serving BS as not changeable target BS, is not promptly supported the switching of current type with this candidate target base station; If candidate target base station is not a base station from home, then serving BS as switchable target BS, is promptly supported the switching of current type with this candidate target base station.
Otherwise, if switchover policy regulation Current Serving BTS supports portable terminal to switch to candidate target base station (macro base station or base station from home) from serving BS, then serving BS with this candidate target base station as switchable target BS.
Step 408, serving BS are returned to portable terminal and are moved the request response, wherein comprise one or more potential target base station.
Because serving BS has sent the preparation handoff request to a plurality of candidate target base station, this moment, serving BS can receive that many are prepared switching request response, and these respond from different candidate target base station, comprising macro base station and base station from home.
So-called potential target base station is: if serving BS is a macro base station, then potential target base station is the candidate target base station (macro base station and/or base station from home) of accepting the portable terminal handoff request; If serving BS is a base station from home, then in the candidate target base station of accepting the portable terminal handoff request, exclude the not changeable target BS of serviced base station conduct in step 407, obtain potential target base station at last.
Preferably, the sign of potential target base station can be formed a potential target base station tabulation, be carried at and move in the request response; Portable terminal is tabulated according to this, confirms the target BS that self will cut.
Step 409, serving BS send to potential target base station and prepare switch acknowledgment message, think that carrying out the switching of subsequent movement terminal from the serving BS to the potential target base station prepares.
It is pointed out that in step 402,, then in preparing handoff request, also can not carry the parameter of expression serving BS type if serving BS is a macro base station; At this moment, in step 403, if candidate target base station is not found this parameter in preparing handoff request, then can give tacit consent to this serving BS is macro base station; In like manner, in step 406,, then in preparing switching request response, also can not carry the parameter of expression candidate target base station type if candidate target base station is a macro base station; At this moment, in step 407, if serving BS is not found this parameter in preparing switching request response, then can give tacit consent to candidate target base station is macro base station.
Figure 5 shows that the schematic flow sheet of the present invention, comprising with the switching type control method embodiment two of base station:
Step 501, serving BS prepares to carry out the handover operation of portable terminal.
In this flow process, in the access service base station, serving BS is carried out handover operation according to the decision-making of communications of Mobile Terminals situation to portable terminal.Serving BS is according to the load condition of self, decision switches to the portable terminal of current its service of support on the less base station of periphery load, the handoff procedure that this shows portable terminal among this embodiment is initiated by serving BS, rather than initiate by portable terminal self; In this process, select one group of candidate target base station by serving BS.Preferably, the unique identification of candidate target base station is formed a candidate target base station list storage in this locality.
Step 502 to the processing of step 509 with step 402 to step 409, repeat no more herein.
Figure 6 shows that the schematic flow sheet of the present invention with the switching type control method embodiment three of base station, in an embodiment, serving BS is before sending the preparation handoff request to candidate target base station, confirm base station type each other between the two at first mutually, and carry out based on the switching type of base station type and control, comprising:
Step 601, with step 401, among this embodiment, the handoff request that portable terminal is initiated to serving BS is the request of moving.
Step 602, serving BS sends the base station type request message to candidate target base station, with the base station type information of request candidate target base station.
Also carry the type information of this serving BS in this step in the base station type request message, the concrete described parametric form of step 402 that can adopt is represented the type information of base station.
Step 603, candidate target base station receive after the base station type request, read the type information of serving BS, and carry out switching type control according to the type of serving BS.
In this step, the method for carrying out switching type control repeats no more with step 403 herein.It is to be noted, in this step, if candidate target base station is not supported the switching of portable terminal from Current Serving BTS to self, then execution in step 604, in the base station type response message of failure, carry an indication, be used for the current candidate target base station in notification service base station and do not support portable terminal to carry out the switching of current type, promptly refuse the handoff request of portable terminal.
Step 604, candidate target base station sends the base station type response to serving BS, wherein carries the type information of this candidate target base station.
If select target BS to support the switching of portable terminal from Current Serving BTS to self, then respond by successful base station type, self type information is sent to serving BS.
Can adopt the described parameter mode of step 402 to represent the type information of base station in this step equally.
Step 605, serving BS receive after the base station type response, read the type information of candidate target base station, and carry out switching type control according to the type of candidate target base station.The processing of this step repeats no more with step 407 herein.
It is to be noted, if candidate target base station supports portable terminal to carry out the switching (i.e. switching from Current Serving BTS to this candidate target base station) of current type, and serving BS also with this candidate target base station as switchable target BS, then continue to carry out follow-up switch step 606～611 between serving BS and this candidate target base station; Otherwise serving BS should not carried out subsequent step with this candidate target base station with the deletion from its candidate target base station tabulation of this candidate target base station.
