Description
Technical field
The present invention relates to the global mobile communication system/general grouping wireless service transmission technology, relate in particular to a kind of raising Packet Service (Packet Service, the method, system and device of service quality PS).
Background technology
Global system for mobile communications (Global System for Mobile Communications; GSM) be most popular a kind of communication system in the mobile communication; Its equipment for radio access network be commonly referred to base station sub-system (Base Station System, BSS).The effect that BSS plays in GSM comprises aspect two: on the one hand, (Mobile Station's BSS MS) links to each other, and carries out transmission, reception and the RRM of wireless signal through the same portable terminal of wireless network; On the other hand; (the Mobile Switching Center of BSS and mobile switching centre; MSC) or Mobile Switching Center Server (Mobile Switching Center Server; MSC Server) links to each other, realize between the MS or functions such as MS is connected with communication between the fixed network user, transfer system information and user profile.
GPRS (General Packet Radio Service) is the abbreviation of GPRS.GPRS user can send and receive data under end-to-end packet transfer mode.The equipment for radio access network of GPRS also is base station sub-system BSS.
As shown in Figure 1, typical B SS comprises two logical nodes: base station controller (Base Station Controller, BSC) and base transceiver station (Base Transceiver Station, BTS).Communication interface between BSC and the BTS is called Abis interface, is used to realize the far-end interconnection between BSC and the BTS.
Travelling carriage need obtain various information from network in order to obtain the network service.Network need be at BCCH (Broadcast Control Channel; BCCH) go up (specifically the content of each message and function are referring to agreement 3GPP TS44.018) such as periodic broadcasting system message 1,2,3,4,7,8,9 and 13; When there is special-purpose Packet Broadcast Control CHannel (Packet Broadcast Control Channel in the sub-district; PBCCH) time, network need be on PBCCH periodic broadcasting grouping system message 1,2,3 and 3bis etc. (specifically the content of each message with effect referring to agreement 3GPP TS 44.060).
In some cases, network side can be made amendment to the cell parameter of the Serving cell of travelling carriage, and as " sub-district forbids inserting " is set, the sub-district that travelling carriage can not select to be in " sub-district forbids inserting " state is a Serving cell.Whether network side can forbid inserting (these system messages are broadcasted) by broadcast cell on the BCCH channel in system message 1,2,2bis, 3,4 or 9.The message element structure at " sub-district forbid insert " field place is RACH Control Parameter (a RACH Control Parameter), and RACH Control Parameter is system message 1,2,2bis, 3, a part of 4 and 9.The structure of RACH Control Parameter is as shown in table 1:
Table 1
By shown in the table 1, the 2nd of the 2nd byte the bit representes whether the sub-district forbids inserting in this structure.Allow to insert if this position is 0 expression sub-district, otherwise forbid inserting.Other field implications of this message element are referring to agreement 3GPP 44.018.
