It can be seen that according to the existing switching process, the original purpose of saving bandwidth by using multiplexing cannot be achieved, which reduces the bandwidth utilization of the system
[0006] In addition, there are multiple data planes on the HGW. When some data planes have problems such as congestion, the TNL on the HGW side cannot be reconfigured, and the associated HNB has no relevant processing regulations.
If you directly register the HNB associated with the deregister, then you need to delete all the HNB and the context of the User, and the HNB initiates a complicated re-registration process, which greatly increases the processingdelay and processing complexity.

Embodiment 1
[0080] For an embodiment of the HGW-initiated HNB MUX reconfiguration method proposed by the present invention, refer to Image 6 , its main steps include:
[0081] Step 601: After the HNB is powered on, the initial configuration is completed through the HMS;
[0082] Step 602: the HNB and the security gateway establish a security tunnel;
[0083] Step 603: HNB and HNBGW establish a reliable signaling connection through the SCTP protocol;
[0084] Step 604: HNB sends a registration request to HNBGW, including HNB location information, HNB unique identifier, HNB Operating Parameters: Such as the selected LAC, RAC, SAC, PLMN Id, Cell Id, etc.;
[0085] Step 605: HNBGW verifies HNB information, decides whether to allow registration, if accepted, and both HNB and HNBGW support RTP multiplexing function, allocate RTP multiplexing port; HNBGW sends HNB REGISTER ACCEPT to HNB, including RTP multiplexing port and other information ;
[0086] Step 606: When the HGW finds that the d...
Embodiment 2
[0092] When a user terminal moves between HNBs under the jurisdiction of the HGW, and the involved HNBs support the multiplexing function of IUH, an embodiment of the TNL update method at the HGW side related to the user's CS RAB is as follows: Figure 7 Shown:
[0093] Step 701: The source HNB sends an RNA: CONNECT message (or RNA: DIRECTTRANSFER if it is already in the soft cut state), including RNSAP: ENHANCED RELOCATION REQUEST to the target HNB, and notifies the target HNB to prepare for relocation;
[0094] Step 702a: The target HNB checks whether the handover is allowed, and allocates a new transport network layer address for each bearer that is allowed to be handed over, and sends HNBAP:TNL UPDATE REQUEST to the HGW to tell the information;
[0095] Step 702b: After the HGW receives the HNBAP:TNL UPDATE REQUEST message sent by the target HNB, if the transmission address IP of the HGW side of the relevant CS RAB is different from the transmission address IP of the mux o...

Abstract
The application discloses a method for reconfiguring the transmission address of an Iuh interface. The method comprises that a household base station gateway HGW notifies a household base station HNB to update a multiplex port and carry the number of an updated multiplex port; that after receiving the notification, the HNB updates the multiplex port and notifies the HGW that the multiplex port has been updated; and that after the HGW receives the notification transmitted from the HNB, data transmission is performed on the updated multiplex port. The method may increase data transmission efficiency and decrease transmission timedelay and processing complexity.
Description
technical field [0001] The present invention relates to a mobile communication system, in particular to a method in a home base station mobile access system that supports transmission address reconfiguration between a home base station (hereinafter referred to as HNB) and a home base station gateway (hereinafter referred to as HGW) interface (hereinafter referred to as Iuh interface). Methods. Background technique [0002] figure 1 It is a schematic diagram of a reference model for a Femtocellaccess network. exist figure 1 In order to save bandwidth, the Iuh interface in 3GPP TS25.467 and TS 25.444 define the Iuh interface data multiplexing (MUX) transmission function, that is, the RTP packets carried by the CS of the user to which an HNB belongs can be multiplexed and transmitted. Specification TS 25.444 specifies how to multiplex and demultiplex the protocol in detail. When HNB registers, if both HGW and HNB support RTP multiplexing function, HGW will allocate MUX UDP...
