- the failure of the service flow only affects itself, and does not affect the operation result of other service flows in the request.
- the convergence sub-layer type is used to identify the binding scope of the multiple service flows.
- the binding scope here includes: Terminal level and business convergence sub-level.
- the above-mentioned combined resource indications can be expressed in the following three ways: (1) The identifier of the merged resource indicator is used in conjunction with the identifier of the service flow, that is, the information of all the service flows is carried in one message, The binding identifier of the merged resource is used in conjunction with the identifier of the service flow; (2) The multiple service flows having the binding relationship use the merged resource indications with the same identifier, that is, the information of all the service flows is carried in one message.
- Step S304 the handover request processing, when the multiple service flows of the terminal are switched from the current serving network to the target network, the target network according to the combined resource indication in the HO-Req message and whether the switching of the multiple service flows is accepted by the target network, Determine whether the terminal is allowed to switch.
- the current serving network may send the HO_Req message to the target network after receiving the handover message from the terminal, or may send the HO_Req message to the target network after the current serving network initiates the handover, and the merge carried in the HO-Req message. If the resource indication indicates that multiple service flows of the terminal are bound, if some of the multiple service flows are rejected by the target network, the target network may determine that the terminal is not allowed to perform the handover. At this time, the target network provides the current service.
- the network sends a response message, and omits part of the information required for the subsequent handover in the response message; the current serving network informs the terminal of the alternate target network that is handed over, wherein the candidate target network does not include the target network that previously rejected the terminal; Each of the multiple service flows is not rejected by the target network, and the target network can determine that the terminal is allowed to perform the handover.
- Step S306 the path pre-establishment process, in the case that the multiple service flows of the terminal are allowed to be switched from the current serving network to the target network, the network where the target network or the data management unit is located according to the merged resource indication in the Path_Prereg_Req message and Whether data channel pre-registration can be established for multiple service flows can determine whether the data channel between the target network and the network where the data management unit is located can be pre-established.
- This step S306 may be performed during the handover preparation phase, or may be performed during the handover action phase, or may not be performed.
- the target network may send a Path_Prereg_Req message to the network where the data management unit is located, or the network where the data management unit is located may send a Path_Prereg_Req message to the target network.
- the resource merge indication in the Path_Prereg_Req message indicates that multiple service flows are mutually bound, if the network where the message receiver is located fails to process the path pre-registration corresponding to some of the plurality of service flows, The network where the target network or data management unit is located is judged not to be pre-built.
- Step S308 the path establishment process, in the case that the plurality of service flows of the terminal are allowed to be switched from the current service network to the target network, and the path pre-registration process is not performed, the network where the target network or the data management unit is located is based on Path-Reg.
- the indication of the merged resource in the Req message and whether it is possible to establish a data channel registration for multiple service flows can determine whether a data channel between the target network and the network where the data management unit is located can be established.
- a data channel between the target network and the network where the data management unit is located can be established.
- Target ASN 1 target network 1
- Target ASN 1 is shown in FIG. 1
- Target ASN 1 is taken as an example for processing other Target ASNs.
- the processing of Target ASN 1 is similar.
- at least one service flow is rejected by Target ASN 1.
- the processing of the above scenario includes the following steps (step 11 - step 17): Step 11, the MS (terminal) sends to the Serving ASN (current service network)
- Step 12 Serving ASN sends HO-Req message to one or more Target ASNs, the HO-Req message includes Authenticator ID and Anchor ASN GW ID (4 Miaoding access service network gateway identifier), and whether multiple service flows are bound to the indication; Step 13, if multiple service flows are marked as binding, then only one service flow is Target ASN
- Target ASN 1 can decide to reject all the service flows of the MS according to the binding indication; then the subsequent context request process and the data channel pre-establishment process of step 14 below do not need to be initiated for Target ASN 1; Binding, the same as the original 3 ⁇ 43 ⁇ 4, Target ASN 1 initiates a context request procedure to the Authenticator ASN; Step 14: The target ASN 1 or the Anchor ASN initiates a data channel pre-establishment process; if there is no binding, the original process is the same; Step 15: The Target ASN 1 sends a HO-Rsp message to the Serving ASN to confirm the handover request; Labeled as Binding, Bay) The HO-Rsp message may not contain the following information: Data Path Info, HO ID (Handover Indicator), Service Level Prediction (Service Level Prediction), HO Process Optimization (Handover Optimization) , HO Authorization Policy Support, Action Time; Data Integrity Info; and BS HO RSP Code can be determined to reject the following information: Data
- the MOB BSHO-RSP message includes a potential switchable target BS (target base station) selected by the one or more networks for the MS, and if the multiple service flows are marked as bound, the Target ASN 1 is not included; Step 17, Serving The ASN sends the HO_Ack to the Target ASN (alternative target network) to which all potential target BSs belong. If multiple service flows are marked as binding, the above target ASN 1 is not included in the candidate target network.
- target base station target base station
- the handover scenario is the AK context acquisition and the data channel pre-registration initiated by the Target ASN
- the multiple service flows of the MS are originally bound
- the MS switches from ASN a to ASN b due to the previous The handover message does not bring the information bound to the MS multi-service flow to ASN b, so the ASN b default MS multi-service flow is not bound.
- the MS switches again at ASN b there is a flow in which ASN b will become the Serving ASN accordingly.
- at least one service flow is rejected by the Target ASN 1, the network environment shown in FIG.
- Step 11 In the same process as the original process, the MS sends a MOB_MSHO-REQ message to the Serving ASN. Initiating a handover, the step is the same as step 11 in the prior art; Step 12, the Serving ASN sends an HO Req message to one or more Target ASNs, the message includes an Authenticator ID and an Anchor ASN GW ID; if the Serving ASN fails to access the other network If the binding information of the multi-service flow is obtained, the HO_Req message will not include whether the multiple service flows are bound or not. The default is not bound.
- Step 13 As long as one service flow is rejected by the Target ASN 1, according to the multiple services of the MS, the target relationship is the binding relationship, and the target ASN 1 smashes all the services of the MS, and the subsequent context request process and the data channel of the step 14 are pre-processed.
- the establishment process does not need to be initiated for the target ASN 1, that is, directly to the step 15; and because the binding relationship information is lost in the previous handover, the Serving ASN in the current handover considers that the multi-service flow of the MS has no binding relationship.
- the error processing is performed.
- the target ASN 1 initiates a context request process to the Authenticator ASN, and proceeds to step 14.
- step 14 the target ASN 1 or the Anchor ASN initiates a data channel pre-establishment process; if not, the same
- the original process is as follows: Step 15: The Target ASN 1 sends a HO Rs message to the Serving ASN to confirm the handover request.
- the HO_Rsp message may not include the following information required for subsequent handover processing: Data Path Info, HO ID (Switch ID), Service Level Prediction, HO Process Op Timization (switching process optimization), HO Authorization Policy Support, Action Time, Data Integrity Info; and BS HO RSP Code can be determined as rejected
- the Serving ASN considers that the multi-service flow of the MS has no binding relationship in the current handover, and the information is the same as the original process. .
- Step 16 The Serving ASN sends a MOB BSHO-RSP message to the MS, where the MOB BSHO-RSP message includes a potential switchable target BS selected by the one or more networks for the MS; if multiple service flow binding relationships are performed according to the MS
- the message does not include the above-mentioned Target ASN 1; however, since the binding relationship information is lost in the previous handover, the Serving ASN in the current handover considers that the multi-service of the MS has no binding relationship, the message may include The foregoing Target ASN 1 ; Step 17, the Serving ASN sends the HO_Ack to the ASN where the potential target BS is located, and the potential Target ASN may include the Target ASN 1 described above.
- the multi-service flow in the request ( Path_Prereg_Req/Path_Reg_Req ) is a binding relationship, and includes the following steps (step 201 - step 211 ): Step 201: The MS sends a MOB_HO-IND (air interface switching indication) to the Serving ASN. The notification is switched to one of the Target ASNs selected by the Serving ASN.
- MOB_HO-IND air interface switching indication
- Step 202 After receiving the MOB_HO-IND message, the Serving ASN sends a HO_Cnf message to the selected Target ASN.
- Step 203 Selecting the Target ASN to Serving The ASN sends a HO_Ack acknowledgment message; Step 204, if the HO_Req or HO_Cnf (Handover Acknowledgement) message includes an Authenticator ID field, and in the previous handover preparation phase, the AK context corresponding to the MS is not obtained, the selection The Target ASN will initiate a context request procedure to the Authenticator ASN to request an AK context for the MS.
- Step 205 if the data channel pre-registration process occurs during the handover action phase, according to an embodiment of the present invention, the Path-Prereg-Req multi-service If the flow binding indicates that the data path establishment failure of the at least one service flow fails, the Target ASN or the Anchor ASN notifies the other party that the data channel pre-delivery establishment fails in the Path_Prereg_Rsp message, and Even if the Data Delivery Trigger field is included in the SF Info in Path-Prereg-Req and the response message, it is not touched.
- Step 206 the MS initiates a network re-entry process to the Target ASN;
- Step 207 the Target ASN initiates a data channel registration process to the Anchor ASN.
- FIG. 4 is a flowchart of the optimization method. As shown in FIG. 4, the following steps are included. (Step S402 - Step S408): Step S402, adding the multi-service flow binding indication information to the handover request message, the path pre-registration request message, or the path registration request message, where the multi-service flow binding indication information is used to indicate the terminal Whether multiple business flows are bound to each other.
- Step S404 the handover request processing, when the plurality of service flows of the terminal are switched from the current serving network to the target network, whether the multi-service flow binding indication information in the handover request message and the handover of the multiple service flows are targeted
- the network accepts and judges whether the terminal is allowed to switch.
- Step S406 the path pre-establishment process, in the case of allowing the multiple service flows of the terminal to be switched from the current serving network to the target network, according to the multi-service flow binding indication information in the path pre-registration request message and whether it is possible to
- the service flow establishes a pre-registration of the data channel, and determines whether the data channel between the target network and the network where the data management unit is located can be pre-established.
- Step S408 the path establishment process, in the case that the plurality of service flows of the terminal are allowed to be switched from the current serving network to the target network, and the path pre-registration process is not performed, according to the multi-service flow binding indication information in the path registration request message And whether it is possible to establish a data channel registration for multiple service flows, and determine whether a data channel between the target network and the network where the data management unit is located can be established.
- the foregoing multi-service flow binding indication information may be the combined resource indication in the foregoing Embodiment 1. It can be seen from the above description that the above steps S404 to S408 are similar to the above-mentioned S304-S308, and are not mentioned here.
- the multi-service flow binding indication information is carried in the handover.
- Request message or path pre-registration request message, or path registration request message.
- AK Authorization Key
- Anchor ASN and Serving ASN are co-configured and R4 (Reference Point 4) data channel pre-registers the scenario initiated by Anchor ASN/Serving ASN; and Anchor ASN and Serving ASN is configured together, And the data channel pre-registration message is merged into the scenario sent in the handover control message; the scenario initiated by the network-initiated handover, and the like. And, for network-initiated handover, initiated by Serving ASN or Serving ASN/Authenticator ASN (when configured together). It should be noted that in the above scenario, except for the network-initiated handover, other scenarios are handovers initiated by the MS.
- the target network can directly make a decision on the handover request of multiple service flows without acquiring the information from the network element that retains the merged resource information or transmitting the handover request information to the network.
- the yuan is then judged by the network element. Therefore, the resource overhead of the related information interaction is saved, and the complete delivery of the original service flow binding information is also ensured.
- the present invention is applicable to other handover action phase scenarios in addition to the scenarios described above for the handover action phase.
- the Target ASN does not receive the HO_Cnf of the R4 (reference point 4); the Serving ASN does not receive the MOB MSHO-REQ message; the Anchor ASN, the Authenticator ASN and the Serving ASN are configured together, and the Serving ASN initiates the channel registration.
