Description
Technical field
The present invention relates to communication technical field, relate in particular to a kind of method of internal user group (ClosedSubscriber Group is called for short CSG) tabulation of more new terminal.
Background technology
In order to keep the competitiveness of 3-G (Generation Three mobile communication system) in the communications field; Speed is faster, time delay is lower, the mobile communication service of personalization more for the user provides; Reduce operating cost of operator simultaneously; 3GPP (3rd Generation Partnership Project, third generation partner program) standard operation group just is being devoted to the research of EPS (Evolved Packet System, evolution system).As shown in Figure 1, EPS is divided into E-UTRAN (Evolved Universal Terrestrial Radio Access Network, evolution wireless network) and EPC (Evolved Packet Core, evolvement network) two parts.
Comprise among the EPC: HSS (Home Subscriber Server; The home subscriber data server), MME (Mobility Management Entity; Mobility management unit), S-GW (ServingGateway, gateway) and P-GW (PDN Gateway, grouped data network gateway); Wherein:
HSS is the permanent storage place of user contracting data, is positioned at the home network that the user contracts;
MME is the storage place of user contracting data in current network, is responsible for NAS layer (Non-Access Stratum, the Non-Access Stratum) signaling management of terminal to network, tracking and paging management function and the bearer management under user's idle pulley;
S-GW is the gateway that core net arrives wireless system, is responsible for function, legal eavesdropping and grouped data route and forwarding capability that service request is initiated to user plane bearer, the metadata cache under the idle pulley of terminal, the network side of core net in the terminal;
P-GW is the grouping domain system (EPS) of evolution and the gateway of this system's external network, functions such as IP (Internet Protocol, the Internet Protocol) address assignment at responsible terminal, billing function, packet package filtration, application of policies.
Comprise eNB (E-UTRAN NodeB, base station) among the E-UTRAN.ENB mainly is responsible for the transmitting-receiving of wireless signal, through air interface and terminal contact.
The NAS signaling be the terminal to the high-level signaling between the MME, the mobile management at main processing terminal and session management only under the situation that exists the NAS signaling to connect between terminal and the MME, just can transmit the NAS signaling.
The state of terminal in EPS is divided into two kinds, and a kind of is the EPS mobility management states, and a kind of is the EPS Connection Management state.The EPS mobility management states is used for monitoring terminal in the relevant information of the mobile management of network, and it has two states: " registration " state and " non-registered " state." registration " state shows that the terminal registers in EPS, network has its contextual information, positional information etc.; " non-registered " state shows that the terminal do not register in EPS, network does not have its contextual information and positional information.The EPS Connection Management state is used for the signaling connection status between monitor terminal and the MME, and it has two states, " free time ", " connection "." free time " state shows does not have NAS (Non-Access Stratum, Non-Access Stratum) signaling to connect between terminal and the MME, can not transmit the NAS signaling; " connection " state shows has the NAS signaling to connect between terminal and the MME, can transmit the NAS signaling.
The service request flow process is the part of mobile communication flow process, and in the EPS system, the NAS signaling that the service request flow process can be set up between terminal and the MME connects, and can let the terminal be " connection " state from " free time " state exchange.
Each sub-district is owing to radio characteristics, and coverage can not be very big.In order to improve the performance of route, a plurality of neighbor cells are combined a formation big tracking area (Tracking Area abbreviates TA as), the tracing section updating flow process is adopted in the renewal of tracking area.Simultaneously; In order to reduce the tracing section updating signaling of (Tracking Area Update is called for short TAU), will distribute to the tracking area tabulation in a terminal (Tracking Area list; Be called for short TA list), endpoint registration is in this tracking area tabulation in all tracking area.The tracking area information at sub-district place is comprised in base station (eNB) and issues in the Cell Broadcast CB at terminal and bring the terminal.
Home eNodeB (Home eNB) is a kind of of base station (eNB), as the dedicated resources of private user, belongs to a few peoples and owns, and is deployed in private sites such as family, group, company or school and uses.Management for ease; Characteristics according to group; The owner of some Home eNodeB forms basic user's group; Be called CSG (Closed Subscriber Group, internal user group), CSG (Closed Subscriber Group) affiliated area is formed in one or more sub-district of the Home eNodeB that these users have.
Each CSG use one in PLMN (Public Land Mobile Network, public land mobile net network) unique sign identify, be called as CSG ID (CSG IDentity, CSG sign).The CSG administrative area can be an one family base station cell covered, also can be all sub-districts that a plurality of Home eNodeB cover.The CSG sign of all sub-districts that CSG user's group is had is all identical.The CSG affiliated area includes only the sub-district of all Home eNodeB of the owner (Owner) of CSG user group.
The CSG region within the jurisdiction only allows to insert through the user who authorizes, and such user has two types: Home eNodeB owner (Owner), guest (Guest); CSG only administers all Home eNodeB of Home eNodeB owner.
CSG user may register to a plurality of CSG user's groups, and CSG user need know the current network that he is registered to like this, and the base station under which CSG has authorized him to insert.Therefore, EPC is CSG user's a CSG tabulation of terminal distribution (allowed CSG list, inside user group list), is used for the visit of control terminal to Home eNodeB.Zone in the CSG tabulation under the CSG of CSG sign representative all allows this CSG user's terminal to insert.If do not have certain CSG ID in the CSG at the terminal tabulation, it just can not insert in all Home eNodeB of this CSG and go.So just can control non-CSG user effectively CSG user is organized dedicated resources, i.e. the visit of Home eNodeB has ensured that CSG user organizes the safety of resource, prevents that dedicated resources from being used by non-CSG user.
After the CSG at terminal tabulation changes, if there is the CSG sub-district in residing zone, current terminal, and this sub-district belong in the tabulation a CSG all, and the terminal inserts macrocellular now, so, the terminal will perform cell reselection under the CSG sub-district.After if the CSG tabulation changes, the CSG sign of the CSG sub-district of the current access in terminal no longer is present in the tabulation, and cell re-selection procedure just will be carried out in the terminal, switch on the available macro cells.
The owner of certain Home eNodeB may be a guest's of visitor's terminal distribution (Guest) authority, and the visitor terminal just can be linked in this Home eNodeB like this, and the CSG tabulation at visitor terminal at this moment needs to upgrade; Simultaneously, if the time marquis that certain user's access right is regained in the CSG decision just needs these users' of change CSG tabulation.Also have a lot of other situation, need the network CSG tabulation in the user terminal that upgrades in time.Like this, the user terminal that network can in time be avoided not possessing associated rights is linked into the Home eNodeB that it can not be visited, and when also can let the user terminal that possesses authority arrive to be authorized to the Home eNodeB of visiting, can in time insert these Home eNodeB.
In the prior art, a kind of method of utilizing the tracing section updating flow process to upgrade the CSG sign in the user terminal is arranged: CSG sign and tracking area identification are placed in the tabulation, manage and upgrade through the tracing section updating flow process.Yet existing employing tracking area flow process is upgraded the method for CSG, and the position that needs to consider base station and Home eNodeB concern problem, need be in tracking area be tabulated two kinds of signs that are uneven in length of preservation, the complicated tracing section updating flow process of evolution system.
