Description
Technical field
The present invention relates to the communications field, more specifically, relate to a kind of route district register method and system and route area list update method and system that the communication system user registers a plurality of routes district that be used for.
Background technology
Characteristics of wireless communication system and fixed communications are to be not have fixing circuit to link to each other between user and the network, and network must be known the geographical position at user place constantly.Like this, the user must tell the position at the present place of network by message when moving, and this is the part of mobile management.
In cellular mobile communication, carry out geography by the form of cellular cell and cover.A typical cellular system is packet switching (Packet Switch the abbreviates PS as) territory of 3-G (Generation Three mobile communication system) (UniversalMobile Telecommunication System abbreviates UMTS as) as shown in Figure 1.
Whole system is divided into wireless system and core net two parts, in wireless system, comprised base station (NodeB) and wireless controller (Radio Network Controller, abbreviate RNC as), NodeB is responsible for the transmitting-receiving of wireless signal, by air interface and user terminal contact, RNC is responsible for wireless resource management and controlled function.In core net, comprised home subscriber data server (Home Subscriber Server, abbreviate HSS as), Serving GPRS Support Node (Serving GPRS Support Node, abbreviate SGSN as) and Gateway GPRS Support Node (Gateway GPRS Support Node, abbreviate GGSN as), HSS is the permanent storage place of user contracting data, be positioned at the home network that the user contracts, SGSN is the storage place of user contracting data in current network, and GGSN is responsible for the gateway function of UMTS and UMTS external network.
Each sub-district is owing to radio characteristics, and what can not cover is very big.In order to improve the performance of route, a plurality of neighbor cells are combined a formation big route district (Routing Area abbreviates RA as), core net is only discerned the route district at user place.The route district information at place, sub-district brings terminal in NodeB issues the Cell Broadcast CB of terminal.
When the user moves two minizones, select a new sub-district, accept the broadcast message of this new sub-district then.If the route district in the cell broadcast information that terminal judges is received is consistent with the route district of the last registration of user, illustrate that this new sub-district still belongs to old route district (as sub-district among Fig. 11 and sub-district 2), need not send Routing Area Update to core net; If the route district of the last registration of route district in the cell broadcast information that terminal judges is received and user is inconsistent, illustrate that the user has moved to new route district (as sub-district among Fig. 12 and sub-district 3), so terminal is initiated the Routing Area Update process, core net will be distributed new casual user's sign, preserve up-to-date route district information, and route district information and casual user's sign of registration returned to terminal together.User of core net can only register a route district at present.
Because wireless characteristic, two sub-districts may cover mutually.When the user is in regional that this covers mutually, may between two sub-districts, select back and forth like this, if these two sub-districts belong to different route districts just, so will not stop initiate the Routing Area Update process to core net.For example, in Fig. 1, belong to the sub-district 2 in different routes district and the zone that there is mutual covering sub-district 3, after the user moves to this zone, select sub-district 2 and sub-district 3 in the future, thereby the triggering routing update process of not stopping can cause taking much more very eating dishes without rice or wine and the resource of network like this.
In order to reduce the possibility that this situation takes place, in the patent 200610011286.9 a solution has been proposed.In this solution, when terminal was initiated Routing Area Update, core net returned to terminal with pre-configured a plurality of routes district, and these a plurality of route area lists are in reciprocity route district.That is to say that the user registers in a plurality of routes district, when terminal moves, can not trigger Routing Area Update like this between this a plurality of routes district.As shown in Figure 1, when terminal was registered in RA1, SGSN registered RA2 simultaneously, and when the user moved between RA1 and RA2, terminal need not be initiated routing update like this.The problem that this scheme exists is that the configuration in the reciprocity route district of core net is static, and the configuration effort amount is huge and be difficult to accomplish reasonable disposition; The another one problem is if the user does not move for a long time, but the still reciprocity route area list of network side preservation when then idle condition has downlink data, can send paging, waste interface-free resources, not enough optimization in all reciprocity route districts of registration.
