[0041] In this embodiment, the communication between the RNC and the CN still uses the existing messages in the RANAP protocol (Radio Access Network Application Protocol). In order to implement the cell update through the Iu interface without changing the existing RANAP protocol, this embodiment puts the content of the cell update request message and the relocation indication message in code streams invisible to the CN for transmission. The RRC Container (Radio Resource Control Container) in the existing RANAP protocol is such a code stream. In the relocation request message, relocation response message and relocation incoming message of the RANAP protocol, there is a unit structure called RRCContainer.

[0042] In this embodiment, the RRC Container structure in the relocation request message is extended, and the contents of the cell update request message and the relocation indication message are added to it, and sent to the CN through the Iu interface. Several structures hav...

[0064] In order to transmit the message originally transmitted through the Iur mouth through the Iu mouth, the present embodiment adopts a newly added RANAP message (hereinafter referred to as the newly added message), and defines the message structure of the newly added message, in the newly added message structure Contains the identification of the destination RNC and the source RNC. In order to use the same message to transmit the content of the cell update message and the relocation indication message, a parameter t is also defined in the new message structure to distinguish it. The specific definition is as follows:

[0065] When t=1, the newly added message structure includes the content of the cell update request message, including the cell update request information sent by the UE and the resources allocated by the TRNC to the UE.

[0066] When t=2, the newly added message structure includes the content of the relocation indication message, which is used to trigger the ...

Abstract

A method for transferring the paging message across wireless network controller without Iur port includes such steps as starting cell updating flow when PCH state of UE reaches TRNC, adding the message of cell updating request to RANAP message by TRNC, transmitting it to CN, transmitting it to SRNC, analyzing it, performing reallocation flow, adding the reallocation message to RANAP message, transferring it to TRNC by CN, analyzing and performing reconfiguration.

Description

technical field [0001] The present invention relates to the third generation mobile communication system, in particular to the paging method of the system. Background technique [0002] TD-SCDMA (Time Division-Synchronous Code Division Multiple Access, Time Division Synchronous Code Division Multiple Access) system and WCDMA (Wide Code Division Multiple Access, Wideband Synchronous Code Division Multiple Access) system have many similarities in the protocol they follow . However, the function of the Iur port in the two 3rd generation mobile communication standards is not the same. [0003] In WCDMA, the principle of soft handover is the priority when switching. For a certain UE, there will be multiple wireless links communicating with it at the same time, and there will also be wireless links across Iur ports. So, we can think that Iur mouth is indispensable to WCDMA. But this interface is different for TD-SCDMA. [0004] For TD-SCDMA, only hard handover is supported now...
