Cordless communication network comprises a plurality of sub-districts 18, each sub-district comprise be used to carry out with 18 overlay areas, sub-district in travelling carriage carry out the basic transceiver subsystem (BTS) 20 of radio telecommunication.BTS entity 20 is connected to one or more base station controllers (BSC) 22.BTS 20 and BSC 22 are called " base station " 19 jointly.Generally speaking; " base station " relate to wirelessly with mobile communications and with for set up, stop, or the supervisory communications dialogue is (for example in addition; Circuit-switched call dialogue, the dialogue of grouping-exchange voice call, other grouping-switched communications session, or the like) and exchange any entity (the perhaps set of entity) of controlling signaling with travelling carriage.Notice that a plurality of BTS can be connected to a BSC in some are implemented.
For the speech business of transfer circuit-exchange, base station 19 is coupled to and is responsible for switching the mobile switching centre (MSC) 24 from Mobile Origination or Mobile Terminated circuit-reciprocal exchange of business.In fact, MSC 24 is the interface that between wireless network and other PSN (for example public switched telephone network (PSTN) 26) or other MSC, signals and the interface of the customer service between them.PSTN 26 is connected to landline terminal, and for example phone 28.
In the voice call session between travelling carriage (for example travelling carriage 16) and landline terminal (for example phone 28), professional through the air interface between travelling carriage 16 and the base station 14, base station 14, MSC 24 and PSTN 26 routing voices.
Cordless communication network is also supported Packet data service, and wherein grouped data is transmitted between travelling carriage and another terminal point, and another terminal point can be that the terminal or another that are coupled to packet data network 34 can transmit the travelling carriage of grouped data.The instance of packet data network 34 comprises private network (for example local area network (LAN) or wide area network) and public network (for example internet).Transmit in grouping-switched communications session that grouped data is set up between travelling carriage and other terminal point.
In order to transmit grouped data, Packet Control Function (PCF) module 32 is coupled in base station 19, and this module management is in BSC 22 and the packet relay of packet data serving node (PDSN) between 30.BSC22 and PCF module 32 can realize on a platform or a plurality of platforms." platform " general reference provides the set of the hardware and software of preplanned mission.
PDSN 30 sets up, keeps and stop the dialogue of link layer and travelling carriage, the Mobile Originated or Mobile Terminated Packet data service of route.PDSN 30 is coupled to the packet data network 34 that connects a plurality of terminal points, for example the computer 36 or the networking telephone 38 (phone 38 is to be equipped with to be used for the phone through the NIC of packet data network communication).The instance of grouping-switched communication comprises web page browsing, Email, text chat sessions, file transfer, interactive entertainment dialogue, IP phone (Internet protocol) dialogue, or the like.
Therefore cordless communication network provides two kinds of dissimilar communications: circuit-switched communication and grouping-switched communication.Circuit-exchange is by communication MSC 24 routes, and divides into groups-exchange by the PDSN30 route of communicating by letter.In circuit-switched communication, during call conversation, set up special-purpose end-to-end channel.Divide into groups-switched communication then utilizes the nothing of the definition of Internet protocol (IP) for example to connect the in-house network working lining.In grouping-switched communication, grouping or other data cell are carried routing information (with the form of the network address), and this routing information is used on one or more paths to destination terminal point routing packets or data cell.
The IP version of a kind of name " Internet protocol " of in request comment (RFC:Request for Comments) 791, describing is known as IPv4; Date in September, 1981; Another that in RFC 2460, describe is called the IP version of IPv6; " IPv6 (IPv6) technical specification, " dates in December, 1998.
In discussion subsequently, with reference to the packet data transmission of travelling carriage.Yet, notice that the technology according to some embodiments of the invention can also be used for circuit-switched communication.
Base station 19 comprises scheduler 40, and scheduling (in the intended manner) travelling carriage 16 is in the enterprising data transfer of each reverse wireless link.Notice and on BTS 20 or BSC 22, to realize scheduler 40, perhaps in above-mentioned two, all realize scheduler.When the scheduling travelling carriage sends grouped data, scheduler 40 specific data speed, time started, the duration through 2 layers of signaling or 3 layer signaling messages.If the standard according to scheduler 40 regulations is dispatched, travelling carriage 16 can send the data (the for example data in the buffer 46 of memory 44) that comprise grouped data.The transmission of this type travelling carriage scheduled mode transmission of being known as.
In predetermined way, base station 19 is gone up to travelling carriage 16 in forward grant channel (F-GCH) and is sent grant message (is 2 layers of message according to embodiment), distributes travelling carriage to go up in reverse packet data channel (R-PDCH) and sends the used data rate of grouped data.R-PDCH is used to travelling carriage and on reverse wireless link, sends grouped data to the base station.Forward grant channel is the fast relatively mechanism of distributing the data rate of travelling carriage on R-PDCH.
Grant message can make and can on independent travelling carriage basis, carry out data rate allocation with concrete travelling carriage as target.According to some embodiments of the present invention, grant message can also with by a plurality of travelling carriages of a base station services as target, thereby cause that a plurality of travelling carriages change data rates.When with by a plurality of travelling carriages of a base station services during as target, grant message is considered to " broadcasting " message.In the configuration of this back, grant message comprises the dedicated indicator that is called as " broadcasting indication ".Refer to transmission with by the indication of two or more travelling carriages of a base station services at this term that uses " broadcasting indication " as target.
Control the data rate of a plurality of travelling carriages through using a broadcast; Can be implemented as the data rate adjustment that the load of management on the reverse wireless link between travelling carriage and the base station is carried out quickly, and less message is arranged between base station and travelling carriage.Through adopting this mechanism, the base station need not continuously to send the data rate that message independently changes travelling carriage to travelling carriage, and this process can be the processing of property time intensive.
Therefore, in a kind of configuration, can be assigned as on R-PDCH to target MS at the grant message that sends on the forward grant channel and to carry out block data communication and data designated speed.In another kind configuration, replace distributing data designated speed to independent travelling carriage, it is that the data rate that changes travelling carriage is indicated in the broadcasting of target that the grant message that on forward grant channel, sends can be provided with all travelling carriages by a base station services.
Broadcasting indication in grant message causes each its data rate of travelling carriage adjustment, and it is maximum from main data rate that it is less than or equal to.Replace scheduled mode transmission, travelling carriage 16 can also be by on R-PDCH, sending grouped data from master mode.Stem from the data service that comprises delay-sensitivity and stream-similar (but not burst) from the data transmission of master mode transmission.For example, the dialogue of the interactive entertainment on packet data network comprises the data flow of delay-sensitivity.Other data transmission that stems from from the master mode transmission comprises that low-rate signaling is professional.Yet, notice that being not limited to from the master mode transmission on reverse wireless link only is above-mentioned business, it can be applied in any type of service.
In master mode, comprise the backward channel that the travelling carriage 16 that will transmit data needn't be waited for the scheduler 40 scheduling travelling carriages 16 in the base station 19.Instead, travelling carriage 16 can specify maximum data rate from main data rate independently to transmit data to be less than or equal on reverse wireless link.In fact, in master mode, not under the situation that the clear and definite set rate that receives from the scheduler 40 of base station 19 on the forward grant channel distributes, travelling carriage 16 can by from master mode sending grouped data from main data rate up to maximum,
Forward grant channel is on R-PDCH, to have been sent the shared channel of the mobile station supervision of data by all.Forward grant channel is drawn together the identifier of discerning each travelling carriage uniquely.In one embodiment, the identifier according to the form of medium access control (MAC) identifier is called " MAC ID ".Visit signaling (request and the permission) process of the MAC layer control air interface in base station and the travelling carriage.
According to some embodiments of the invention, the grant message in the forward grant channel comprises two fields: the MAC id field that comprises Mobile Station Identifier; Data rate assignment field with the data rate of intended target travelling carriage.For distribute data designated speed, the MAC id field in the grant message to be set to the numerical value of the travelling carriage pointed of recognition data rate assignment information uniquely to target MS.Replacedly, the MAC id field can be set to provide the predetermined value of above-mentioned broadcasting indication.The broadcasting indication is the indication to all travelling carriages that can on R-PDCH, move, and their data rate of travelling carriage is set to smaller or equal to maximum from main data rate.In one exemplary embodiment, the MAC id field is set to binary value 00000000 the broadcasting indication is provided.In other embodiments, his predetermined value of also available MAC ID provides the broadcasting indication.
