Abstract
The invention discloses a method of transmitting paging type 1 messages between a radio network controller and an indirect port of a base station. Page indication-bitmap effective indication marks are added in type 3 data frame structure of a high speed down going share channel; the radio network controller puts the paging message of a core network into a paging buffer zone; when paging occasions or paging receiving occasions come, the radio network controller sends the high speed down going share channel type 3 data frame to the base station from an Iub port; if the page indication-bitmap is carried in the frame, the valid indication mark of the page indication-bitmap in the frame is set to be valid, otherwise the mark is set to be invalid; the base station chooses related channel to send messages according to the valid indication marks of the page indication-bitmap in the frame after receiving the high speed down going share channel type 3 data frame. The method provided by the invention can reduce the redundancy of data and greatly improve the resource transmitting utilization of the Iub port.
Description
Technical field
The present invention relates to the method for transmission of messages in the mobile communication system, in particular, relate to a kind of after introducing HSPA+ (high-speed packet inserts and strengthens) technology, the method for improved Iub mouth (interface between radio network controller and the base station) paging Class1 transmission of messages.
Background technology
Continuous development along with 3G (Third Generation) Moblie, on the basis of HSDPA (sharing downlink physical at a high speed inserts) technology and HSUPA (sharing ascending physical signal at a high speed inserts) technology, released the HSPA+ technology, its objective is in order to improve data-transmission efficiency, to reduce time-delay.In this technology, the logic channel PCCH (Paging Control Channel) that has proposed bearing call Class1 message also is mapped on the HS-DSCH (high speed descending sharing channel), and Iub mouth HS-DSCH type 3 data frame structures that define according to 3GPP agreement TS25.435 encapsulate, as shown in Figure 1, wherein CFN (Connection Frame Number) is the opportunity of UE (subscriber equipment) paging receiving Class1 message, be that paging receives opportunity, PDU blocks (protocol Data Unit piece) is the paging Class1 message that UE need receive, PI-Bitmap (paging indication-bit map) is the paging indication bitmap that UE need receive, and sends to NodeB (Node B) then.
As shown in Figure 2, in TDD (time division duplex) system, paging block comprises paging indicator collet and beep-page message piece two parts, and wherein the paging indicator collet is the paging indication bitmap that UE need receive, and the original position of paging indicator collet is the paging occasion of UE; The paging grouping of beep-page message piece is the paging Class1 message that UE need receive, and the original position of paging grouping is that the paging of UE receives opportunity.The beep-page message piece comprises Npch paging grouping, and Npch is disposed by high level.
Therefore, RNC can be when paging occasion arrives, indicate bitmap to be packaged into HS-DSCH type 3 Frames separately paging and send from the Iub mouth, then when the paging reception arrives opportunity, the paging Class1 message of corresponding paging grouping is packaged into HS-DSCH type 3 Frames separately and from the transmission of Iub mouth, wherein carries invalid PI-Bitmap; Perhaps, RNC also can be when the paging reception arrives opportunity, the paging Class1 message of corresponding paging grouping is encapsulated in same HS-DSCH type 3 Frames the inside with the paging indication bitmap of next paging cycle and sends from the Iub mouth.If a kind of scheme before RNC adopts then when sending the paging Class1 message of each paging grouping, there is no need to carry PI-Bitmap in fact; If RNC adopts a kind of scheme in back, the paging indication bitmap that then only need carry next paging cycle when sending the paging Class1 message of paging grouping 1 gets final product, when sending the paging Class1 message of other paging groupings, there is no need to carry PI-Bitmap in fact.Therefore, for the TDD system, when the Iub mouth adopts HS-DSCH type 3 frame structures transmission paging Class1 message, many times can there be the situation of PI-Bitmap information redundancy, thereby causes the waste of the defeated resource of Iub oral instructions.
In FDD (Frequency Division Duplexing (FDD)) system, when UE arrived in paging occasion, paging receiving indication bitmap was 1 if detect corresponding paging indicating bit, then was offset beginning paging receiving Class1 message after the fixed intervals.Therefore, if network side needs paging UE, RNC (radio network controller) need indicate paging bitmap and corresponding paging Class1 message to send to NodeB respectively at two HS-DSCH type 3 Frames.Wherein carry HS-DSCH type 3 Frames of paging Class1 message, can carry the paging indication bitmap of next paging cycle simultaneously.If next paging cycle does not have paging Class1 message to need to send, then the PI-Bitmap that carries in HS-DSCH type 3 Frames is nonsensical in fact, only can bring the waste of the defeated resource of Iub oral instructions.
In sum, many times, the PI-bitmap territory of carrying in Iub mouth HS-DSCH type 3 frame structures is always not effective.For the FDD system, the PI-bitmap maximum length is 18 bytes, and for the 1.28Mcps system of TDD, the PI-bitmap maximum length reaches 44 bytes, and this will cause information redundancy and transmission resource waste.
Summary of the invention
The technical problem to be solved in the present invention is, a kind of transmission method of Iub interface paging type type 1 message is provided, and can reduce the redundancy of data, improves the utilance of the defeated resource of Iub oral instructions greatly.
In order to address the above problem, the transmission method of Iub interface paging type type 1 message of the present invention comprises:
