Abstract
The invention discloses a resource reservation method and a system thereof. The method is characterized in that during an interoperation process of a LTE system and a 2G system, when an eNodeB located in the LTE system needs to carry out resource reservation for subordinate UE, a resource reservation request message is sent to an BSC located in the 2G system, wherein the message carries related information of the UE which is needed during the resource reservation; after receiving the resource reservation request message, the BSC determines whether wireless resource reservation can be performed for the UE; if the wireless resource reservation can be performed for the UE, a resource reservation response message is returned to the eNodeB after the reservation is successful, wherein reserved wireless resource information is carried. By using the scheme of the invention, signaling cost can be reduced and processing time delay can be shortened.
Description
Technical field
The present invention relates to mobile communication technology, particularly method for obligating resource and the system in the interoperability process of Long Term Evolution (LTE, Long Term Evolution) system and Generation Mobile Telecommunication System (2G, Second Generation) system.
Background technology
At present, in mobile communication system, if relate to the interoperability with different system, need to be by between source access network elements, source core net, target side core net and target side access network elements, carrying out Signalling exchange, the resource reservation that is source application target side by reciprocal process, after reserving successfully, then start to carry out concrete interoperability flow process.
Switch to example with the LTE system to the different system of 2G system, as a user terminal (UE, User Equipment) in the time of will carrying out different system switching, at first, need to carry out Signalling exchange between source LTE Access Network and core net, target side 2G Access Network and core net, in order to be the Radio Resource of UE application target side.
In actual applications, the process of the above-mentioned Radio Resource for UE application target side can be called to the switching set-up procedure.Fig. 1 is the schematic diagram of existing switching set-up procedure, Fig. 2 is the flow chart of existing switching set-up procedure, be labeled as 1 the dotted line with arrow in Fig. 1 corresponding to the step 21 in Fig. 2, be labeled as 2 the dotted line with arrow in Fig. 1 corresponding to the step 22 in Fig. 2, the like.
Wherein, shown in Fig. 2, flow process comprises the following steps:
Step 21: be arranged in the UE of LTE system to evolved base station (eNodeB) the reporting measurement message for self serving.
In measurement message, portability has sign, the Reference Signal Received Power (RSRP of UE, Reference Signal Receiving Power), Reference Signal Received Quality (RSRQ, Reference SignalReceiving Quality) and neighboring BS information etc.
Step 22:eNodeB determines whether to initiate the different system switching from the LTE system to the 2G system to UE, if so, to the mobile management entity (MME, Mobility Management Entity) in the LTE core net, sends handover request message.
In handover request message, portability has switch reasons and UE at beared information of cell-of-origin etc.
After MME in step 23:LTE core net receives handover request, by the interface between core net, to the GPRS serving GPRS support node (SGSN, Serving GPRS Support Node) in the 2G core net, send the forward direction RELOCATION REQUEST message.
Wherein, the abbreviation that GPRS is general packet radio service (General Packet Radio Service).
In the forward direction RELOCATION REQUEST message, portability has the beared information of UE in cell-of-origin and user plane information of UE etc.
SGSN in step 24:2G core net sends RELOCATION REQUEST message to corresponding base station controller (BSC, Base Station Controller).
Corresponding BSC refers to after UE is switched in the 2G system, is the BSC of UE service.
After step 25:BSC receives RELOCATION REQUEST message, determine whether to reserve for UE carries out Radio Resource, if so,, after reserving successfully, the SGSN in the 2G core net returns to relocation response message.
SGSN in step 26:2G core net returns to the forward direction relocation response message to the MME in the LTE core net.
MME in step 27:LTE core net returns to switching command to eNodeB, and the switching set-up procedure completes.
Can find out, in above-mentioned resource reservation mode, need to just can complete relevant Signalling exchange by core net, the network element related to is more, causes Signalling exchange flow process complexity, thereby has increased signaling consumption and processing delay.
