Description
Technical field
(Code Division Multiple Access, CDMA) technology relate in particular to a kind of method of calling double-mode terminal to the present invention relates to code division multiple access.
Background technology
CDMA 2000 standards are protocol suites, comprise CDMA 2000 1x and CDMA 2000 1x enhancement mode-high-speed datas (Evolution-Data Only, EV-DO).CDMA 2000 1x can provide the data service of speech business and 307.2Kb/s in the wireless transmission bandwidth of 1.25MHz, CDMA 2000 1x are quite ripe at present, and are commercial in the success of a plurality of countries and regions; CDMA 2000 1xEV-DO use at data and optimize, and the data rate up to 2.4Mb/s can be provided in the wireless transmission bandwidth of 1.25MHz, have the very high availability of frequency spectrum, and CDMA 20001xEV-DO has also had the scale commercialization at present.
Because the 1x network has been built in most of CDMA operations commercial city, therefore, how introduce the focus that the EV-DO network becomes operator on the 1x network, the interoperability that how to solve two dual-mode terminals when network coexisted also becomes the focus that operator and equipment vendor pay close attention to.Wherein, described dual-mode terminal is meant the hybrid terminal of supporting 1x and EV-DO simultaneously, can be operated in 1x network and EV-DO network simultaneously, registers at two networks respectively.The business of initiatively initiating for dual-mode terminal is if the 1x network then preferentially selected in the circuit domain voice, if packet data application is then preferentially selected the EV-DO network.
EV-DO Rev.0 technology write the 3GPP2 standard in 2000, it is to design under the background that the internet data downloading business impacts, and its design original intention is to satisfy the needs of getting online without being tethered to a cable, and wireless downloading at a high speed is provided.Do not have mutual interface between EV-DO Rev.0 network and the 1x network, have only the information of understanding two networks by terminal, as lane place, paging etc.Referring to EV-DORev.0 network configuration shown in Figure 1, mainly comprise packet data serving node (Packet Data Serving Node, PDSN), Packet Control Function (Packet Control Function, PCF), access network (AccessNetwork, AN), AN authentication and authorization charging (AAA) and access terminal (Access Terminal, AT).Wherein, AT inserts AN by air interface (Air Interface), and AN is used for mobile management, and AN AAA is used for access authentication.EV-DO network and 1x network can shared PDSN, need not newly-built PDSN when building the EV-DO network generally speaking, but to increase AN, PCF and AAA newly.
EV-DO Rev.A is the evolution of EV-DO Rev.0, be primarily aimed at VOIP and the key technology of EV-DO carried out comprehensive optimization with other wireless data services application, can provide low-cost, high power capacity IP phone/visual telephone (VOIP/VT), broadcast multi-broadcasting, press-and-talk business such as (PTT) carry out platform, and on voice user's capacity, have more advantage than 1x.Referring to shown in Figure 2, the network configuration of the network configuration of EV-DO Rev.A and EV-DO Rev.0 is close substantially, difference has been to increase the interface A1/A1p between the mobile switching centre/mobile soft switch center (MSC/MSCe) of AN and 1x network, and the air protocol that has strengthened the EV-DO network makes the signaling of 1x network can be encapsulated in transmission in medium access control (MAC) bag of EV-DO network.The A1/A1p interface is the bidirectional interface of standard, can carry beep-page message that MSC sends to AN, layer three signaling, short message (SMS) etc., also can carry the business request information etc. that AN sends to MSC/MSCe.
For paging from the EV-DO network, the AN of EV-DO network judges at first whether dual-mode terminal is in business state at the 1x network, if, AN sends the paging request to the MSC/MSCe of 1x network, at 1x ICQ dual-mode terminal, the notice dual-mode terminal has the calling from the EV-DO network by MSC/MSCe; Otherwise AN is at EV-DO ICQ dual-mode terminal.
Referring to shown in Figure 3, in order to guarantee carrying out smoothly from the EV-DO ICQ, when dual-mode terminal when the 1x network carries out business, the MSC/MSCe of 1x network need send event notice (Event Notification) message to the AN of EV-DO network, and notice AN dual-mode terminal carries out business at the 1x network.Like this, as from the paging of EV-DO network the time, AN smoothly paging to dual-mode terminal.
For the common dual-mode terminal of two nets registration, as from the paging of 1x network the time, MSC/MSCe judges at first whether the 1x positional information of dual-mode terminal is effective, if the 1x positional information is effective, MSC/MSCe is then at 1X ICQ dual-mode terminal; If the 1x positional information is invalid, the EV-DO positional information is effective, and MSC/MSCe then sends the paging request to the AN at dual-mode terminal place, at EV-DO ICQ dual-mode terminal.
But, for paging,, whether be in business state etc. at the 1x network as dual-mode terminal because MSC/MSCe can't learn the current concrete situation at the EV-DO network of dual-mode terminal from the 1x network, when determining the paging mode of dual-mode terminal deviation may appear therefore.Such as, for just in the EV-DO network, carrying out professional dual-mode terminal, as from the paging of 1x network the time, if the 1x positional information of dual-mode terminal is effective, MSC/MSCe then can be at 1x ICQ dual-mode terminal, that is to say that dual-mode terminal need interrupt ongoing data service in the EV-DO network at the paging time-slot of 1x network, monitors the paging of 1x network.The data service that this is ongoing to dual-mode terminal, especially some real-times require will inevitably have a negative impact as VOIP, VT, PTT etc. than higher data service, cause the interruption of data service, thereby influence quality of service.In addition, for paging, when the 1x of dual-mode terminal positional information is invalid, if MSC/MSCe can not learn the current more specific location information in the EV-DO network of dual-mode terminal from the 1x network, then MSC/MSCe may paging less than dual-mode terminal, thereby cause paging failure.
