Description
Technical Field
The present invention relates to the field of communications technologies, and in particular, to a mobility management method and device for a terminal.
Background
The current wireless networks have various categories, including GSM (Global System for mobile communications)/WCDMA (Wideband Code Division Multiple Access), CDMA2000 and TS-CDMA (time synchronization Code Division Multiple Access), which can provide mobile services for users. These wireless networks have similarities in both architecture and service capabilities, and the architecture of the wireless network is described below with WCDMA as an example. As shown in fig. 1, includes: an MSC (Mobile switching Center) server and a CS-MGW (Circuit Switch Media Gateway) located in a CN (Core Network) belong to a Circuit domain Core Network; and SGSN (Serving GPRS Support Node) and GGSN (Gateway GPRS Support Node), belonging to a packet domain core network; a BSS (Base Station System) and AN RNS (Radio Network subsystem) belong to AN (Access Network) and are shared by a circuit domain core Network and a packet domain core Network. The core network is responsible for service control, and is used for checking service subscription, providing service logic, and the like, while the access network provides access capability for users, and provides basic signaling and media transmission channels for users to acquire services, which is the basis for users to acquire services.
At present, if a user needs to acquire a service from a circuit domain core network MSC through a circuit domain access network, the user needs to be located in a circuit domain coverage area, and usually needs to perform location update to the MSC, and then the user can acquire the service from the MSC, where there are two location update methods:
the method comprises the following steps: as shown in fig. 2, the method comprises the following steps:
step s201, when a UE (User Equipment) needs to perform location update, in order to establish a message transmission channel with an MSC/VLR (visual Local Register), a radio resource connection between the UE and an RNS/BSS needs to be established by using a radio resource management function provided by a circuit domain access network, so as to obtain a signaling transmission channel.
Step s202, the UE sends a location update message to the MSC/VLR through the RNS/BSS.
Step s203, if the user is a subscriber, the MSC/VLR will accept the location update request of the user and return a location update acceptance to the UE. Before acceptance the MSC/VLR may go to the HLR to check the subscription information of the subscriber.
And step s204, the UE and the RNS/BSS release the established radio resource connection.
The second method is shown in fig. 3, and comprises the following steps:
step s301, when the UE is located in an area covered by CS or PS (Packet Switch, Packet domain), the UE may perform location update of the circuit domain by using the Packet domain with the opportunity of performing routing domain update to the Packet domain, which is embodied as that the UE sends a CS and PS combined routing area/location area update request to the SGSN.
Step s302, SGSN sends location update request to MSC/VLR.
Step s303, if the user is a subscriber, the MSC/VLR will accept the location update request of the user and return a location update accept to the SGSN. Before acceptance the MSC/VLR may go to the HLR to check the subscription information of the subscriber.
Step s304, the SGSN returns a combined routing area and location area update request accept message to the UE.
In the process of the second method, although the UE performs the location update of the circuit domain by using the procedure of the packet switched domain routing domain update, the location update still aims at the circuit domain access, and the user still performs the location update in the circuit domain access mode when he wants to perform a service (for example, make a call), but cannot perform the location update in the packet switched domain access mode (for example, cannot make a VoIP call).
In the prior art, SAE (System Architecture Evolution) is a packet network Architecture, and the main entities include MME (Mobility Management Entity), PDN GW, PCRF (Policy Control and Charging Rules Function), and the like. The SAE has a roaming architecture and a non-roaming architecture, and provides a relatively efficient packet transmission network for users, which can be used for providing VoIP (voice over IP) services for the users. The network configuration of SAE is illustrated below by taking a non-roaming architecture as an example. As shown in fig. 4, the MME mainly has the functions of: mobility management, such as attachment handling for users; and participating in the establishment of the user IP bearer. The PDN GW (Packet Data Network GateWay) mainly has the following functions: IP address allocation management; carrying policy control; and filtering the data packet. The SAE can also support other non-3 GPP Access modes, such as WLAN (Wireless Local Area Network), WiMAX (Worldwide Interoperability for Microwave Access).
If the user is in the coverage area of the 2G/3G circuit domain access mode and is also in the coverage area of the enhanced packet domain (hereinafter referred to as packet domain) access mode (such as SAE/LTE), the UE can complete the location update of the UE to the circuit domain core network by utilizing the packet access instead of the circuit domain access, so that the UE can perform the circuit domain service. The UE can simultaneously complete the registration of the packet switch and the circuit switch through the packet switch access, and compared with the mode of respectively accessing from the packet switch and the circuit switch, the registration of the packet switch and the circuit switch is respectively carried out, so that the number of times of interaction on a wireless interface is reduced (by half), and the reduction of the transmission burden of the wireless interface is facilitated.
The packet access is described below by taking LTE as an example, and a specific process is shown in fig. 5, which includes the following steps:
in step s501, the UE sends a CS and EPS joint tracking area/location area update request to the MME.
Step s502, the MME sends a location update request to the MSC/VLR.
Step s503, if the user is a subscriber, the MSC/VLR will accept the location update request of the user and return a location update accept to the MME. Before acceptance the MSC/VLR may go to the HLR to check the subscription information of the subscriber.
Step s504, the MME returns a joint tracking area and location area update request accept message to the UE.
The inventor of the invention finds the following defects in the prior art:
because there may be multiple MSCs in one network, when the packet network is an LTE or other non-GRPS access mode, there is no prior art to describe how the mobility management function (MME for the LTE access mode) in the packet network selects one MSC as the target MSC for the location update of the UE, so as to implement registration of the UE in the MSC.

Detailed Description
An embodiment of the present invention provides a mobility management method for a terminal, as shown in fig. 6, including the following steps:
step s601, when the UE is powered on, or the UE has a circuit switched domain location change (including entering another circuit switched domain from one circuit switched domain, or entering a circuit switched domain for the first time), the UE performs a location update operation. The UE sends a joint update request to a mobility management function entity (MME) in a packet network (such as SAE), wherein the request carries the circuit domain location information of the UE. Wherein, before the UE sends the joint updating request, the method also comprises the step that the UE acquires the circuit domain position information: and the UE receives the broadcast information of the local circuit domain, selects the circuit domain network according to the broadcast information and further selects a cell under the circuit domain network, wherein the identification information of the cell is the circuit domain position information.
When circuit domains and non-circuit domain (packet) networks of a plurality of operators exist, in order to enable the UE to select a circuit domain or a packet network of the same operator for location updating (when the circuit domain network and the packet network selected by the UE in the registration process belong to different operators, and the registration fails because of no interconnection and interworking between the operators). The circuit domain and packet network association information can be sent to the UE through a network side device (such as MME); or configuring the association relationship information between the packet network and the circuit domain network in the UE or a Subscriber Identity Module (SIM) card of the user, and the UE can determine the associated circuit domain network and the packet network through the association relationship information. Wherein the associated information includes: sending related circuit domain network information such as a network number to the UE in a packet network in a broadcasting mode or the like; or sending related packet Network information such as a PLMN (public land Mobile Network) number to the UE in a circuit domain Network by means of broadcasting or the like; or the same network identification information, such as a network number, is sent to the UE in the packet and circuit domain networks, respectively.
Step s602, the mobility management function determines a target MSC for location update according to the circuit switched domain location information of the UE. And the MME determines a target MSC according to the circuit domain position information of the UE and by combining the corresponding relation between the circuit domain position information and the MSC, wherein the corresponding relation can be configured in the MME.
Step s603, the mobility management function interacts with the target MSC, and the MSC updates the state of the UE.
After step s603, if the UE moves to an area without coverage of the circuit switched access radio signal and the original packet access radio signal still exists, the UE may indicate to the MSC that the user is unreachable through a mobility management function in the packet network. Thereafter, if the UE enters an area with CS coverage, the UE may go through steps s601 to s603 again, and indicate to the MSC that the UE is reachable.
After step s603, if the UE moves to an area not covered by the packet access radio signal and the original circuit domain access radio signal still exists, the mobility management function in the packet network sends an indication to the MSC, and the MSC does not send a page to the UE through the packet network. The UE can perform location updating through the circuit domain access, so that the UE can perform service through the circuit domain access, and when the MSC receives a location updating request of the UE, the MSC selects the circuit domain access to send paging to the UE.
An embodiment of the present invention is shown in fig. 7, which further describes a process of determining an association relationship between a packet and a circuit domain network by a UE, and includes the following steps:
step s701, the packet network such as SAE broadcasts the associated circuit domain network identification information to the UE, where the network identification information is, for example, PLMN identification of the circuit domain network.
And step s702, the UE performs residing according to the circuit switched network determined by the association information.
Of course, the circuit switched network may also broadcast the associated packet network identification information, and the UE performs location update according to the indicated packet network; or the identification information of the circuit domain network and the packet network broadcast the same packet network identification information, and the UE can also be associated with the circuit domain network and the packet network.
The second embodiment of the invention: the UE performs circuit switched domain location update through packet access, as shown in fig. 8, including the following steps:
step s801, when the user UE is powered on, or the circuit domain location changes, or first enters the circuit domain coverage area, the UE sends a tracking area or location area joint update request to the mobility management function in the packet network such as SAE, where the request carries the circuit domain location information of the UE.
Step s802, the mobility management function determines a target MSC (for example, MSC1 in fig. 8) for location update according to the circuit switched domain location information of the UE and the corresponding relationship between the circuit switched domain location information and the MSC.
Step s803, the mobility management function interacts with the target MSC, and the MSC updates the registration status of the UE.
Step s804, the mobility management function returns a registration success to the UE.
The third embodiment of the invention: and after the position updating is completed, the UE moves to the processing of only the packet access area. Assume that the UE has completed the processing in the second embodiment first, and then the UE moves and the original circuit domain access signal is lost. As shown in fig. 9, the method comprises the following steps:
step s901, when the user UE is powered on, or when the circuit domain location changes, or when the user UE enters the circuit domain coverage area for the first time, the user UE sends a circuit domain access loss indication to the MME.
Step s902, MME sends UE circuit switched domain access loss indication to MSC, MSC records this event, and thereafter MME is no longer sending paging to UE.
Step s903, the MME sends a circuit domain access loss indication response to the UE.
The fourth embodiment of the invention: and after the position updating is finished, the UE moves to the area only accessed by the circuit domain. It is assumed that the UE has first completed the processing in embodiment two, and then the UE has moved and the original packet access signal is lost. As shown in fig. 10, the method comprises the following steps:
in step s1001, the UE finds a packet access signal loss.
Step s1002, the UE sends a location update request to the MSC.
Step s1003, after receiving the request, the MSC finds that the UE has performed location update through the MME, and then sends the paging to the UE through the circuit domain access instead of sending the paging to the UE through the MME, unless the MSC receives the location update request from the MME again.
Step s1004, the MSC returns a location update accept to the UE.
The fifth embodiment of the invention: and after the position updating is finished, the UE moves to the area only accessed by the circuit domain. It is assumed that the UE has first completed the processing in embodiment two, and then the UE has moved and the original packet access signal is lost. As shown in fig. 11, the method comprises the following steps:
in step s1101, the MME discovers that the UE is dropped in packet access, for example, a periodic tracking area update timeout.
Step s1102, the MME sends a UE network drop indication to the MSC.
Step s1103, after receiving the request, the MSC does not send a page to the UE through the MME, but sends a page to the UE through the circuit domain access unless the MSC receives a location update request or a UE network restoration instruction from the MME again.
Step s1104, the MME returns a UE drop indication response to the MSC.
