The method is used when a mobile station is in a service interaction state and base station switching is carried out. The method has the obvious advantages that the flexible mobile station dynamic switching method based on service priority in a heterogeneous network environment improves the call completing rate of new calling during a mobile station switching process and lowers the call drop rate of existing calling, and requirements on user service quality of the network are met by mobile station switching optimization.

Description

A kind of mobile station handover method of the service priority based in heterogeneous network
Technical field
The present invention relates to communication technical field, particularly relate to travelling carriage handover mechanism in network.
Background technology
The wireless communication system emerged in an endless stream, for the network environment that the user provides isomery, comprises Wireless Personal Network
(as Bluetooth), WLAN (wireless local area network) (as Wi-Fi), wireless MAN (as WiMAX), public mobile network (as 2G, 3G, B3G), satellite network, and AdHoc network, wireless sensor network etc., as shown in Figure 1.Although these wireless networks provide diversified communication mode, access means and ubiquitous access service for the user, but, realize self-organizing, the self adaptation of real meaning, and realize thering is the service that end-to-end QoS guarantees, also need to take full advantage of the complementary characteristic between heterogeneous networks, realize organically blending of heterogeneous wireless network technology.Heterogeneous network converged is the inexorable trend of next generation network development.Under the heterogeneous network converged framework, the key issue that must consider and solve is: how to make any user can obtain the service with QoS assurance in any place at any time.No matter the key technology research that possesses the QoS assurance under isomerous environment is the resource for the optimization heterogeneous network, still, for the design of collaborative work mode between access network, all is very important, and has become an important research aspect of heterogeneous network converged.At present, the research of heterogeneous network converged mainly concentrates on RRM and mobile management two aspects.
Wherein, the research of the travelling carriage handover mechanism between heterogeneous network, due to diversity and the uncertainty of isomerism, resource and the user's request of each network, is difficult to realize seamless switching and reduces the impact of switching on business.
When travelling carriage moves to another communication subnet from a communication subnet, the destinations traffic subnet can be set up new being connected with travelling carriage, being connected between travelling carriage and old communication subnet is released, need carry out handover, be used to guarantee the continuity of Radio Resource when mobile environment changes.Handoff procedure must be quick and precisely, and the selection of destinations traffic subnet must be best.The service quality that handover success rate provides the user comprises the call completing rate of calling and calls out cutting off rate, and cutting off rate is larger on user's impact than call denial.
In sum, be necessary to set up efficient, the feasible travelling carriage switch determining method that meets heterogeneous-network service dynamic characteristic and demand, realize the optimization of travelling carriage performance of handoffs.
Summary of the invention
Technical problem to be solved by this invention is: improve the dynamic switching method that adopts service based priority in heterogeneous network, the QoS of survice guarantee while realizing the travelling carriage switching.
The present invention solves the problems of the technologies described above adopted technical scheme to be: when travelling carriage, when the service interaction state carries out the base station switching, design a kind of travelling carriage dynamic switching method of service based priority; It is characterized in that: the Dynamic Elastic changing method by invention based on different business priority, can reduce the drop rate of travelling carriage when switching in the service interaction state by the method, improve the service quality of network, comprise the following steps:
A, the priority of differentiated service at first, real time business is high-priority service, non-real-time service is low priority traffice, high-priority service comprises the new call business of travelling carriage of real-time travelling carriage switch call business and real time business, low priority traffice comprises the switch call business of non-real-time service travelling carriage and the new call business of travelling carriage of non-real-time service, and set up the constraints of the QoS meet the business transmission requirement, and to the new call business higher limit of travelling carriage of real time business
Figure 201310373283X100002DEST_PATH_IMAGE001
regulated; And, to there being high-priority service or the low priority traffice that can not meet QoS constraints, adjust the new call business higher limit of travelling carriage of real-time travelling carriage switch call business higher limit and real time business .
B, based on steps A, by judgement travelling carriage in the i of base station is new, call out and higher limit, the real-time travelling carriage switch call business upper limit of base station and difference and the base station between the non real-time travelling carriage switch call business upper limit of the new call business of travelling carriage of the higher limit of the switch call business of the new call business higher limit of travelling carriage of switching channels number and real-time travelling carriage switch call business higher limit, real time business, non-real-time service travelling carriage, non-real-time service the real-time travelling carriage switch call business upper limit and the relation between the difference between the non real-time travelling carriage switch call business upper limit, to new travelling carriage is new, call out and handover request adopts corresponding behavior.
In described steps A, the priority of travelling carriage switch call business is higher than the new call business of travelling carriage of real time business in real time, the priority of non real-time travelling carriage switch call business is higher than the new call business of travelling carriage of non-real-time service, and travelling carriage switch call business higher limit is in real time
