The invention relates to the communication technology field, and specifically to the technologies and network structures of wireless communication and wired communication, and particularly relates to a communication network system that converges a wireless mobile network with a wired discontinuous mobile network, and the method thereof.
Although conventional communication networks are capable of interconnecting and interoperating, these different communication networks are independent of each other due to the fact that the various independent communication core networks use different communication access network technologies, for example, the different wireless mobile access technologies, such as DAMPS, cdma IS-95A/B, GSM/GPRS, PDC/PHS, 3G WCDMA, CDMA2000, and so on are respectively connected to different wireless mobile core communication networks that are independent of each other. A traditional wired fixed access communication POTS corresponds to a wired fixed PSTN/ISDN core communication network; and IP packet access such as Ethernet, xDSL, a cable modem, and so on corresponds to a PDN packet network, the Internet, an IP communication network, and so on.
The wireless and mobile feature of conventional wireless mobile communication network technologies brings great flexibility and convenience to a user's communication, but the problems therewith, such as the insufficiency and costliness of wireless frequency resources, low security and privacy, bad communication environment, comparatively poor communication quality, requirements for high power radio frequency technologies, along with the increasing complexity of wireless mobile communication and control technologies, are inevitable and unsolvable. The wired communication network technologies, such as PSTN, have various advantages, such as friendly communication environments, abundant wired bandwidth resources, comparatively high communication quality, simpler communication and control technologies compared to wireless mobile technologies, and security and reliability. However, the deficiencies of these technologies, such as fixing, stillness, non-removability, dedication, and non-sharing, have severely affected the economic benefit of wired communication technologies, thus restricting their further development. Although IP telephony network technologies based on IP technology, such as H.323, SIP, and soft-switch, have many advantages in terms of the IP technology itself, their communication relies on translation between an IP address/domain name and an IP address, and the IP address associatively corresponds to a packet access network equipment and an access position. As a user equipment changes its access port and position, it is necessary for packet core network and packet access network equipment to reallocate and configure its IP address. This makes it difficult to implement bidirectional communication with numerous traditional PSTN/ISDN and PLMN user equipment and lacks the telephone service of communicating via a unique number and the management and control mechanism of telecommunication, unlike a PSTN or a PLMN telecommunication network. In particular, IP Internet network technology is based on a non-real time service bearer and a connectionless-oriented service, along with hybrid transmission and the switching of a real time service and a non-real time service, further lack the QoS and security assurance of a telecommunication network. The problem of not being able to convergently share the user equipment, the access network, and the core network in the communication technology field has led to an increase in the complexity of interconnection and interoperability among the different communication technologies, along with multiple and redundant coverage and the repeated construction of a multitude of communication network technologies, especially various wireless mobile technologies, as well as unsharing and the waste of unused communication resources, especially wired communication resources, and ultimately, an increase in cost and a decrease in economic benefit.
One objective of invention is to provide a communication network system that converges a wireless mobile network and a wired discontinuous mobile network, to overcome the disadvantage of not being able to convergently share the above communication network resources. Thus, the system of the invention has the advantages of a wireless mobile communication system, such as being fixed and convenient, along with the advantages of a wired communication network system, such as abundant bandwidth resources, a friendly communication environment, high communication quality, simple technologies, and being safe and reliable.
Another objective of the invention is to provide a method applicable to a communication network system that combines a wireless mobile network and a wired discontinuous mobile network, to overcome the deficiency of not being able to convergently share different communication network technologies, in particular a wireless mobile communication technology and a wired communication technology, thus solving various problems with present communication technologies, such as redundant coverage and the waste of communication resources, making complex interconnection and interoperability relationships among different communication technologies easier, and implementing convergent sharing in the wired communication environment for different wireless mobile communication technologies.
The invention provides a communication network system that converges a wireless mobile network and a wired discontinuous mobile network. To attain the objects described above, the convergent communication network system provided by the invention comprises: a user equipment, an access network and a wireless/wired convergent mobile core network. The user equipment is connected to the access network system in a wired or a wireless manner, the access network may access a plurality of user equipment, and may be connected to the wireless/wired convergent mobile core network via a circuit switched domain traffic data and control signaling interface or a packet switched domain traffic data and control signaling interface, and the wireless/wired convergent mobile core network may be connected to a plurality of access networks, and may be interconnected to and communicate with external core networks of the same type, as well as other external communication networks, such as PSTN/ISDN, PLMN, PDN, Internet, and so on. There are three types of user equipment: a wired user equipment, a wireless/wired multi-mode user equipment, and a wireless user equipment, The access network may be formed in two ways, one is with the wired access network and the wireless access network independent of each other, and the other is with a wired end user access equipment, a wireless base station, and a convergent access controller incorporating a wireless access base station controller with a wired access end office access equipment.
To attain the above objects, the communication network system converging a wireless mobile network and a wired discontinuous mobile network is a convergence of a wireless mobile communication technology and a wired discontinuous mobile communication technology, and a convergence of wireless mobile communication and wired discontinuous mobile communication in terms of the systematic functions and structure of a core network, an access network, a user equipment, and a full network. Logically, the convergent communication network is divided into two independent layers: a wired discontinuous mobile communication network and a wireless mobile communication network. The wired discontinuous mobile communication network is a novel wired communication network with discontinuous mobility, which is simpler than wireless mobility, and may be regarded as a particular application of the wireless mobile communication technology in wired access. The wireless mobile communication network is a conventional communication network, such as a 2G GSM/GPRS or IS-95A/B, an IMT-2000 WCDMA, cdma2000 or TD-SCDMA, or a communication network in a future wireless mobile communication technology. Therefore, the wired user equipment is a novel wired communication user equipment with a discontinuous mobile function; the wireless user equipment is a wireless communication user equipment in a 2G GSM/GPRS or IS-95A/B, an IMT-2000 WCDMA, cdma2000 or TD-SCDMA, or a future wireless mobile communication technology; and the wireless/wired multi-mode user equipment is a multi-mode user equipment converging one or more of the wireless communication technologies in a 2G GSM/GPRS or IS-95A/B, an IMT-2000 WCDMA, cdma2000 or TD-SCDMA, or a future wireless mobile communication technology, with a wired discontinuous mobile technology. The wired user equipment is connected to the wireless/wired convergent mobile core network via a wired access network supporting discontinuous mobility for the wired discontinuous mobile communication; the wireless user equipment is connected to the wireless/wired convergent mobile core network via the wireless access network for the wireless mobile communication; the wireless/wired multi-mode user equipment may be connected to the wireless/wired convergent mobile core network via the wireless access network or the wired access network for the wireless mobile communication or the wired discontinuous mobile communication, and may hand over between the wireless access and the wired access, and between the wireless mobile communication and the wired discontinuous mobile communication; all the user equipment respectively use a unique and fixed number for communication. The access network is responsible for controlling and managing the wireless access resources and the wired access resources, for cooperating with the wireless/wired convergent mobile core network to provide the user equipment and the wireless/wired convergent mobile core network with wireless or wired bearer services, along with wireless or wired access bearer services, and for supporting wireless mobility and wired discontinuous mobility management and communication management. Under support and cooperation from the user equipment and the access network, the wireless/wired convergent mobile core network provides the user equipment with communication management, wireless mobility and wired discontinuous mobility management, along with security management, and is responsible for allocation management of interfaces and channel resources between the access network and the mobile core network, along with network operation and maintenance management, and the wireless/wired convergent mobile core network is interconnected to and communicates with external core networks with the same type, along with other external communication networks via communication interfaces and protocols.
Compared with conventional separated communication technologies, the communication network system converging a wireless mobile network and a wired discontinuous mobile network and the method thereof not only incorporates the respective advantages of the wireless mobile communication and wired communication technologies and networks, but also overcomes their disadvantages and solves problems with the conventional wireless mobile communication and wired communication, such as the different technologies, mutually separated networks, complex interconnections and interoperability, the waste and non-sharing of communication resources, and the high cost.
