In this paper, based on the current domestic corporate customers integrated access to market competition, standing at city branch of China Mobile in perspective of mobile operators to provide integrated services to corporate clients access to alternative access technologies when the group network model and client integrated access solutions.
Telecom operators, the Group's full-service competitive with the arrival of the era and became the focus of competition. Group customers in the implementation process of information technology programs, around the city branch of China Mobile's customers access to building is put in place an integrated impact of information technology is a key element of success.
1, group customers integrated access technology selection
Group customers can be divided into the cause of organ-based government, banking and financial securities based, enterprise-based industry group, education / school-type and the hotel / office type. Compared to ordinary users, group customers as business operators, the performance of large, complex business types, require high quality of service. Table 1 shows the various types of groups dedicated access customers demand simple comparative analysis.
Table 1 all types of groups dedicated access customer needs analysis
Current industry common corporate clients access to technology shown in Figure 1.
Figure 1 Group means client access technology
Around the city on the China Mobile subsidiary, the Group's customers access to the building should be integrated with MAN and co-ordinated, using access technology is relatively mature. Several access technologies in corporate clients access to a brief analysis of the positioning is as follows:
1) to the new metro transport network is based on an MSTP technology to build the main integrated access network. Can also use the original base station transmission equipment can be upgraded to MSTP conditions to the base station to provide corporate customers rely on the comprehensive line access. Not in place in the MSTP and fiber resources have temporarily achieved by way of PDH Optical access line customers.
2) for the LAN-based broadband access should be provided the export route for the main business LAN, in principle, participate in the construction of CPN, operation and maintenance and management.
3) the WLAN as a service to the target user is recommended. Can guide users to build WLAN, providing appropriate technical support, but most importantly through the WLAN to provide wireless LAN users to export the circuit to drive green WLAN access business.
4) 3.5G wireless access to users with fixed rate relative to the LMDS low, but can also provide users with 10/100Base-T, E1, ISDN, PSTN and other interfaces to meet the comprehensive general users access needs. This device can be applied to small and medium bandwidth demand is not big users. 3.5G systems can be used to access both the backbone transmission circuit for export for the CPN; also be directed at individual user terminals providing broadband services.
2, Group customers integrated access network model
2.1 MSTP + LAN Model Ways: base stations and indoor coverage at the transmission system configuration access layer MSTP equipment, providing 10/100Base-T port access. Users can make use of the resident if there is an integrated cabling system can achieve great customer access. Large customers are very dense region can add a small layer switches.
Applicable: The customer is relatively high bandwidth requirements, and relatively dense, such as urban office.
2.2 PDH transmission circuit access mode
Ways: directly through the transmission network for large customers E1, N E1 transmission circuits, access CMNET line access routers.
Application: distributed large customers from the base station transmission of more recent, such as industrial parks.
2.3 MSTP + XDSL mode Ways: base stations and indoor coverage in the transmission system settings MSTP equipment, connect a small DSLAM, use of office telephone line resources, the realization of user access to XDSL. This way you can have voice taking into account the needs of users.
Application: office telephone lines are available resources.
2.4 MSTP + WLAN mode Ways: during the construction of indoor coverage while building WLAN network. The realization of large customers with wireless access.
Application: the lack of access line resources to wired access, if the campus, factory, etc..
2.5 3.5G wireless access model
Implementations: 3.5G-multipoint fixed wireless access is a structure. The main system components generally include central station, terminal station and network management system three parts, exceptional circumstances stand in the center between base stations and terminals to relay through the relay stations. And user terminals connected (via UNI interface) can be a single user terminal, it can be a CPN.
Application: distance, area and line gap so large.
3, the Group access to enterprise customers integrated business solutions side
Group provides business customers, including integrated access to data services and voice services. With China's mobile softswitch network construction provincial dry, the Group's IP voice service customers will be mainly hosted by the soft-switching network, the original IP front end access would no longer develop. As present, China Mobile also has no local fixed-line business licenses, throughout the city office during construction of the Group Integrated Access customers should pay attention to the following principles:
(1) an integrated approach to seize the group user access to avoid the simple voice service with the local fixed network operators face the main conflict.
(2) data-access-based, voice-secondary (can not open first), data-driven business voice services.
(3) and local voice services to avoid direct conflict between the main fixed network operators, primarily to carry out long-distance VoIP services.
(4) make full use of the original users of the routing of property rights and reduce access costs.
(5) does not appear similar to the PBX as the equipment, the main fixed network operators to avoid local interference.
(6) carried out with groups of office users OA system combines the integrated services, value-added services, increase the adhesion degree of the user.
3.1 Solution 1 Group customer type
Enterprise PBX existing local fixed-line operators access to PSTN, internal resources only twisted pair
