Description
Technical field
The present invention relates to terminal and obtain the technology of the network information, specifically, relate to the method that a kind of terminal is obtained network support bi-carrier or multi-carrier transmission ability.
Background technology
At existing GPRS (General Packet Radio Service, GPRS) in the system, a MS (Mobile Station, travelling carriage) can only be an enterprising line data transmission of carrier frequency, bandwidth of operation is 200KHz, and obviously this has just limited the transmission rate of data.For example, under present EGPRS (Enhanced GPRS strengthens GPRS) system, the theoretical maximum velocity of 8 time slots is 473.6kbps.Along with the development of data services, existing speed can not satisfy user's demand.In light of this situation, how tame communication apparatus manufacturer has proposed a new notion: descending two carry (or overloadings) transmission and up two (or overloading) transmission of carrying.As its name suggests, (or overloading) transmission in descending two years is exactly to break through the bandwidth constraints that gsm system follows always, and a MS can carry out descending reception simultaneously on more than one carrier frequency; (or overloading) transmission in up two years is exactly that a MS can carry out up transmission simultaneously on more than one carrier frequency.Like this, bandwidth of operation just becomes 200*N KHz (N is the carrier frequency number), and corresponding message transmission rate is also according to the proportional improve of carrier frequency number.Still be example with present EGPRS system, distributing the theoretical maximum velocity of 8 time slots on the carrier frequency is 473.6kbps, if MS can receive simultaneously or send on 2 carrier frequency, speed can reach the requirement of 3G system to speed near 1M so.Introduce two (or overloading) transmission technologys of carrying of downlink or uplink, the life cycle that has prolonged gsm system greatly only need simply be upgraded on the existing system basis, just can greatly improve transmission rate.Both saved the investment of operator on equipment, and can satisfy carrying out of new business again, vast potential for future development will have been arranged.
Usually, if MS will carry out above-mentioned descending two carry (or overloading) transmission or up two (or overloading) transmission of carrying, at first, must know earlier whether network supports descending two carry (or overloading) transmission or up two (or overloading) transmission of carrying.At present, when MS is inserting, can not know at once whether network was supported two years or the situation of overloading, but whether support two carrying or overloading to network-reporting oneself earlier, network then distributes carrier frequency resource according to the MS that reports to that receives, that is to say, learn MS itself when network based report of receiving and support two carrying or overloading, if this network is also supported descending two carry (or overloading) transmission or up two (or overloading) transmission of carrying, network will distribute two or more carrier frequency resources to MS so, and MS is only after the message of receiving the network-assigned carrier frequency resource, if when carrying the information of two or more carrier frequency resources in the discovery message, MS is just known network support descending two carry (or overloading) transmission or up two (or overloading) transmission of carrying, and MS self just can use descending two (or overloading) transmission or up two (or overloading) transfer function that carries of carrying.Obviously, such process complexity is loaded down with trivial details, and knows whether network was supported two years or the process of overloading, had also taken valuable Internet resources.
