Description
Technical field
The present invention relates to a kind of be used for digital cordless phones (Digital Enhanced CordlessTelecommunications, DECT)-voice-over-net phone (Voice over Internet Protocol, VoIP) system of netsurfing, apparatus and method.
Background technology
Before the arriving of mobile phone (cellular phone) epoch, the DECT specification provides the technology of general wireless communication.The DECT system comprises a DECT fixed part (fixed part) and at least one DECT portable part (portable part), and for example wireless (cordless) DECT handset telephone (handset), this fixed part have at least one base station (base station).Basically, the dect standard specification only contains the wireless transmission interface (air interface) between DECT fixed part and the DECT portable part.Dect standard specification definable application category (application profile) to be to include extra standard, for example DECT wireless transmission interface this how to be used in the certain applications.For instance, (Generic Access Profile GAP) is basic standard to common access standard, and it defines one group of minimum pressure demand (mandatory set ofrequirements), guarantees interoperability.Common access standard is the basic norm of the token sound of all other DECT.
Fig. 1 is an example schematic of known DECT system.As shown in Figure 1; One DECT handset telephone warp is " wireless transmission interface " thus, also is wireless connections (radio link), is connected with external network and be linked to a DECT base station; For example be connected to Public Switched Telephone Network (Public SwitchedTelephone Network, PSTN).
The DECT base station is at least one channel, to transmit continuously, gives the DECT handset telephone so that a beacon (beacon) function to be provided, and locks beacon.The DECT handset telephone that is locked to a beacon transmissions can analyze the broadcast message of beacon since then, finds out the access rights (access right) whether this DECT handset telephone has this system, to set up a communication link.
Based on security reason, the DECT base station has one built-in (built-in) communication protocol, does not login in advance in this DECT base station of the DECT of this DECT base station handset telephone access to take precautions against.In the case, a DECT handset telephone is merely able to communicate by letter with specific DECT base station, and these specific DECT base stations are DECT base stations of logining in advance.Promptly, the DECT handset telephone does not have complete mobility (mobility) like mobile phone, can roam in the network with wireless signal scope yet.
Though DECT is a kind of access technique; And its specification standards do not contain the locomotivity in the whole network territory; But can through the additional applications category how to define via with the communication interface of other networks; Extend this locomotivity, for example DECT/ global system for mobile communications (Global System for MobileCommunications, GSM) interworking standard (Interworking Profile; GIP), integrated services digital network (Integrated Services Digital Network, ISDN) interworking standard.In addition on the one hand; As long as provide wireless range therewith wireless terminal device have suitable access right; This wireless terminal moves that (CordlessTerminal Mobility, CTM) access standard (Access Profiles) defines the service of moving of this wireless terminal and allows wireless terminal device to rove between the network.This wireless terminal mobility access standard class is similar to the DECT-GSM interworking standard, and different place is that this wireless terminal moves the locomotive function that the access standard is not limited in existing GSM network.It is to switch (circuit switch) framework via traditional circuit mobility is provided that this wireless terminal moves the access standard agreement.Wireless terminal mobility access standard Ji and common access standard between compatibility.Yet its complexity can make to have DECT and wireless terminal to move the equipment price of access standard agreement expensive, so more not attractive on market.
Now, the fast development of VoIP makes that the application of this DECT-VoIP is very popular, and many DECT-VoIP (under common access standard agreement) handset telephone can buy on the market, and great majority are to be applied at home or office.Fig. 2 is an example schematic of known DECT-VoIP system configuration.As shown in Figure 2, a DECT-VoIP system comprises at least one DECT-VoIP base station and at least one DECT-VoIP handset telephone.A this DECT-VoIP base station and a gateway (gateway) combine.This DECT-VoIP system is through suitable network access facility and binding; For example through asymmetrical digital user line (Asymmetric Digital Subscriber Line; ADSL) modem (modem); Or network user's switch (Internet Protocol Private Branch eXchange, IP PBX), and be connected to a Internet.It should be noted that in the aforesaid framework that this voip gateway must earlier preset voip user's account number.In this way, this DECT handset telephone can be dialed VoIP through voip user's account number preset in the DECT base station that is stored in integration.Yet the mobility of this DECT handset telephone of this architectural limitation because this DECT handset telephone is merely able to dial VoIP through specific DECT-VoIP base station, and connects voip gateway so far via fixing communication line.
Because voip technology itself just has the function of roaming, aforesaid restriction is mainly from two factors.To be the common access standard agreement of DECT based on safety consider first factor need go to produce one and encrypt golden key (cipher key), prevents that communication from being invaded.Each time when a DECT handset telephone is placed on the carriage of DECT base station, or when the user pins the login button (registration button) on DECT handset telephone and the DECT base station simultaneously, will produce a new encryption gold key.This encrypts golden key and has only this DECT handset telephone and DECT base station to know.Moreover if the DECT handset telephone then can't be linked to other DECT base stations when not knowing the encryption gold key of DECT base station.Second limiting factor is as the broadband (broadband) to the Internet with ADSL because the VoIP account number is the gateway end of login at the DECT-VoIP of this integration.Because the VoIP account number is not stored in the DECT handset telephone, so the DECT handset telephone can't be linked to the DECT-VoIP gateway that another has been integrated, because this another DECT-VoIP gateway does not have the VoIP account number of corresponding this DECT handset telephone.
Because the DECT technology has many advantages; For example spectrum efficiency (spectrum efficiency) and radio access reliably; And in many kinds are used, for example in business environment, meet cost benefit, so the task of top priority is to cook up a solution; Realize the feasibility of DECT-VoIP roaming, and then the another kind that makes the DECT technology become more attractive is selected.
