Embodiment
Below in conjunction with drawings and the specific embodiments to the detailed description of the invention.
The Notification Method of precedence information provided by the present invention, UE by Source BS in the process that TargetBS switches, the precedence information of UE is notified to Target BS.As Source BS and Target BS during, obtain the precedence information of UE usually by MSC, and the precedence information that obtains is sent to Target BS by the management of same mobile switching centre; Perhaps obtain the precedence information of UE, and the precedence information that obtains is sent to Target BS by MSC by Source BS.When SourceBS by MSC management and Target BS when being different from the 2nd MSC management of a MSC, obtain the precedence information of UE usually by a MSC, and the precedence information that obtains sent to Target BS by the 2nd MSC; Perhaps obtain the precedence information of UE, and the precedence information that obtains is sent to Target BS by a MSC and the 2nd MSC by Source BS.
Particularly, when UE switches related Source BS and Target BS by same MSC management, as shown in Figure 1 at the precedence information informing mechanism of Target BS; Fig. 1 is the precedence information notice flow chart of a preferred embodiment of the present invention, and this flow process may further comprise the steps:
Step 101: determine in communication process will be when Target BS switches as UE, and UE can notify the Source BS at its current place; Source BS knows that UE will be when Target BS switches, to the handover request (Handoff Required) of MSC transmission at UE.
Step 102: when receiving the Handoff Required from Source BS, MSC obtains the precedence information of UE from attaching position register (HLR), and the precedence information that obtains is carried in the handoff request (Handoff Request) sends to Target BS.MSC can use prior art and obtain described precedence information from HLR.
In actual applications, also can can't help MSC from HLR, to obtain the precedence information of UE, preserve but in advance the precedence information of UE is sent to UE.Like this, when UE made Source BS know that UE need switch by Signalling exchange, UE can carry the precedence information of self in signaling; Source BS then can obtain the precedence information of UE from the signaling from UE, and the precedence information of UE is carried among the Handoff Required sends to MSC.
Step 103:Target BS reads the precedence information of UE from the Handoff Request from MSC, can also further preserve the precedence information that reads.
So far, Target BS has just obtained the precedence information of UE smoothly, can use the service that prior art provides the precedence information of rank and acquisition to match for UE.
Target BS also sends switching request response (Handoff RequestAcknowledge) to MSC.
Step 104: when receiving the Handoff Request Acknowledge from Target BS, MSC sends switching command (Handoff Command) to Source BS.
Step 105: when receiving the Handoff Command from MSC, Source BS guides UE to switch to Target BS, and sends to MSC and to switch beginning (Handoff Commenced) message.
Step 106: when UE successful switch during to Target BS, Target BS sends to switch to MSC and finishes (Handoff Complete) message.
Step 107: when receiving the Handoff Complete from Target BS, MSC sends disconnect command (Clear Command) to SourceBS.
Step 108: when receiving the Clear Command from MSC, the communication resource that distributes for UE before Source BS discharges, and take out stitches to the MSC transmission and to finish (Clear Complete) message.
As seen from Figure 1, when the handoff procedure of UE under same MSC just begun, Target BS just can obtain the precedence information of UE; And, in follow-up UE handoff procedure even after UE finishes switching, the service that Target BS can provide the precedence information of rank and acquisition to match for UE.
When UE switches related Source BS and Target BS respectively by different MSC management (as: Source BS is managed by a MSC, and Target BS is managed by the 2nd MSC), as shown in Figure 2 at the precedence information informing mechanism of Target BS; Fig. 2 is the precedence information notice flow chart of another preferred embodiment of the present invention, and this flow process may further comprise the steps:
Step 201: determine in communication process will be when Target BS switches as UE, and UE can notify the Source BS at its current place; Source BS knows that UE will be when Target BS switches, to the Handoff Required of MSC transmission at UE.
Step 202: when receiving the Handoff Required from Source BS, the one MSC obtains the precedence information of UE from HLR, and the precedence information that obtains is inserted the assignment of priority access channel indicate in (PACAIndicator), this PACAIndicator is carried in the interoffice forward direction handoff request (FACDIR2) sends to the 2nd MSC again.The one MSC can use prior art and obtain described precedence information from HLR.
In actual applications, also can can't help a MSC from HLR, to obtain the precedence information of UE, preserve but in advance the precedence information of UE is sent to UE.Like this, when UE made Source BS know that UE need switch by Signalling exchange, UE can carry the precedence information of self in signaling; Source BS then can obtain the precedence information of UE from the signaling from UE, and the precedence information of UE is carried on sends to a MSC among the Handoff Required.
Step 203: when receiving the FACDIR2 from a MSC, the 2nd MSC reads the precedence information that is comprised among the PACAIndicator of FACDIR2, and the precedence information that reads is carried on sends to Target BS among the Handoff Request.
Step 204:Target BS reads the precedence information of UE from the Handoff Request from the 2nd MSC, can also further preserve the precedence information that reads.
So far, Target BS has just obtained the precedence information of UE smoothly, can use the service that prior art provides the precedence information of rank and acquisition to match for UE.
Target BS also sends Handoff Request Acknowledge to the 2nd MSC.
Step 205: when receiving the Handoff Request Acknowledge from Target BS, the 2nd MSC is forward direction switching request response (facdir2) between a MSC forwarding office.
Step 206: when receiving the facdir2 from the 2nd MSC, a MSC sends Handoff Command to Source BS.
Step 207: when receiving the Handoff Command from a MSC, Source BS guides UE to switch to Target BS, and sends Handoff Commenced message to a MSC.
Step 208: when UE successful switch during to Target BS, Target BS sends Handoff Complete message to the 2nd MSC.
Step 209: when receiving the Handoff Complete from Target BS, the 2nd MSC sends inter-office switchover to a MSC and finishes (MSONCH) message.
Step 210: when receiving the MSONCH from the 2nd MSC, a MSC sends Clear Command to Source BS.
Step 211: when receiving the Clear Command from a MSC, the communication resource that distributes for UE before Source BS discharges, and to MSC transmission Clear Complete message.
As seen from Figure 2, when the inter-office switchover process of UE had just begun, Target BS just can obtain the precedence information of UE; And, in follow-up UE handoff procedure even after UE finishes switching, the service that Target BS can provide the precedence information of rank and acquisition to match for UE.
By Fig. 1, Fig. 2 as can be seen, Target BS can obtain the precedence information of UE in the UE handoff procedure, thereby can carry out differentiated service to UE according to the precedence information of UE, makes that the utilization of Internet resources can be more reasonable; And at high priority UE, owing to UE can both enjoy and the corresponding high-level service of the high priority of self in handoff procedure even after finishing switching, so user satisfaction can be improved significantly.
The included key content of described precedence information is the Priority cell, and BS is that UE carries out differentiated service according to the content in the Priority cell usually.The form of Priority cell as shown in Figure 3, among Fig. 3, Call Priority represents the call priority of UE; Queuing Allowed represents whether the calling of UE allows queuing; Preemption Allowed represents whether UE can seize other user's communications resources.
In fact, can further enable the 6bit among the Reserved (being the reserved field in the Priority cell) in the Priority cell or the field of 7bit position, the title of this field is defined as: whether CanBe Preempted (can be referred to as and can be seized field), can be seized with the communication resource of expression UE.Particularly, the value of Can Be Preempted is 0 o'clock, and the communication resource of expression UE can be seized; The value of Can Be Preempted is 1 o'clock, and the communication resource of expression UE can not be seized.
In actual applications, Can Be Preempted value that can high priority UE is set to 1, represents that the communication resource of this high priority UE can not be seized; And the Can BePreempted value of low priority UE is set to 0, represents that the communication resource of this low priority UE can not be seized.Certainly, operator can also be according to the value of practical application scene setting Can Be Preempted.
The above is preferred embodiment of the present invention only, is not limited to protection scope of the present invention.
