3G network merges with WLAN system
The intersection of Motorola and the intersection of wireless network and the intersection of solution and the intersection of Division and the intersection of Chinese and Cai, general manager of district,
At present, 3G networking of China Mobile, China Telecom and CHINAUNICOM is in the ascendant. One that is with WCDMA/ CDMA2000, especially TDSCDMA industry chain is constant and ripe, 3G user’s quantity is increasing constantly, 3G mobile communication application service is abundant day by day, the contradiction between the business demands of bearing capacity and high flux, high bandwidth of the mobile network is conspicuous day by day. The distribution and business of the mobile subscriber use the characteristic to often have ” The focus ” The characteristic, in the particular commerce, traffic and administrative area, the more centralized the mobile subscriber is, the flowrate is the larger in the average and twinkling of an eye. Difficult applied demand of user’s multimedia of data for supporting a large number of of 3G technology, and WLAN, as the wireless data technology possessing the high cost performance and disposing ability on a large scale, the pressure of air interface of unloading 3G that it can be very good, so ” 3G +WLAN ” Both as the supplemental development strategy and become operator’s common choice.
The integration of 3G network and WLAN system is not merely the integration of the aspect of network, will involve the integration and integration of business of the subscriber station. Look from aspect of network, the integration of different access ways has already got very good settlement, users can use the same account number, the same terminal station to launch the business in the same or different area through 3G and WLAN; And the relevant switching problem between different networks, it is not merely the requirements for network, also include it to the requirement for terminal and backstage supporter’s support system, the solutions in theory are all ripe at present, but still await different network manufacturers and terminal and supporting the customization of the manufacturer and cooperating in actual commercialization the day after tomorrow. As to the terminal station, the numerous manufacturers including Motorola can offer TDSCDMA/WCDMA/CDMA2000 +WLAN (WAPI) Terminal station last this demand, be on this basis, can last terminal station of technical grade Motorola, in order to meet the particular trade application of 3G +WLAN under the abominable work environment. Finally, the most important thing is too the business is merged, not merely authorize in unison, charge etc. in unison, also including the seamless of the business is merged, can be in the course of moving such as users, enjoy incessant high-speed video service and music ringing business,etc. at the same time.
Rely on not having innovation, researches and develops and application experience for many years that line thickness is leading the land, especially radio local area network field, Motorola is in leading position of industry in new-standards such as 802.11n, moving IP, network management and online security,etc., new technology. On the Chinese market, Motorola participates in WLAN networking of the Chinese operator actively, dispose the high-power AP apparatus to realize radio coverage for operator’s scale, make its input-output ratio reach optimumly. Standard, test, pilot project and application still in 3G +WLAN network of Motorola,etc. of various fields launch cooperation with the operator, serve the numerous networks of operator province, has made the good result.
Motorola put out many kinds of new products, new technologies recently to support the integration solution of 3G +WLAN, including: The brand-new one, supporting low-powered and wireless access point AP650, AP7131 and AP7181 of high-power of 802.11n,etc.. These products can cooperate with the present 3G network, realize better tetherless access quality, subscriber data of the higher speed are inserted, thus in the intersection of focus and area, take place frequently the intersection of crest value and flowrate and area that multiple WLAN cover with realize the effective flowrate is shared.
Meanwhile, all serial wireless switchboards move IP, support the mobile subscriber’s movement agent and HA in Motorola, can well support the switch between 3G network and WLAN network. For example, when users use WLAN, once users move the service which cause WLAN to stop, moving the node will use the service of IP layer in spare state, offered by 3G network at once, , as pass on address jointly, in order to move registered news of IP, notify the HA the intersection of 3G and the intersection of network and assigned IP address. This one registers the original tunnel service of no-break of news, but notify and move the newest position of node to the HA, let the HA change to jointly pass on on 3G network the final position of the tunnel at present the address rapidly. Later, with users’ constant movement, if WLAN resumed serving again, moving the node will get back to WLAN again too. If get back to WLAN network that originally inserted, moves the node and sends and registers news, the terminal of the tunnel is that the outside agent that WLAN offers passes on the address to notify the HA and upgrade once again at once; If reach the new WLAN network or insert WLAN network for the first time, need inserting and authorizing.
In the future, the network that the integration technology of 3G +WLAN will move towards the depth merges, the ultimate goal of this integration is that the seamless will be covered, that is to say ” Tight coupling ” . With the applied maturity of 3G network technique, the intersection of 3G and the intersection of +WLAN and terminal the intersection of industry and ripe, the intersection of WLAN and commercialization, gradual completion and the intersection of network connection and empirical constant accumulation to run support system of 802.11n, the factor that it is determined that the network seamless of 3G network and WLAN covers will not merely depend on technology, should depend on some other respects even more, for example the fast popularization of the wireless city can be accelerating the integration process of 3G +WLAN objectively, and the integration of 3G +WLAN will promote, optimize resource utilization rate and input-output ratio in operation of wireless city of the operator conversely.
