Abstract

A method for realizing network access for single number standby of PCS user and 3G user includes following contents. Setting PCS or 3G network as the priority network. Integrated intelligence HLR assigns the same user number for PCS and 3G user, and establishes the correlative connection between two networks user information by setting a free user type value between networks. The user that has a PCS and 3G bi-mode bi-readiness cell phone uses the same user number. The phone can register PCS network and 3G network at the same time in the normal, and communicates with the other user by using the priority network. When the priority network is useless, the HLR returns location information of the other network in answer of calling routing and SMS routing. It ensures the communication is unblocked.

Description

TECHNICAL FIELD The present invention relates to a network access method for a dual mode terminal in the field of mobile communications, and more particularly to a PCS user and a 3G user using the same number in dual standby. A method of implementing network access. BACKGROUND After a 3G network of a telecommunication service carrier (such as telecommunications or China Netcom) is completed, a user of a PCS (PCS Personal Communication System) has a requirement to use a 3G service without changing the number, but In the initial stage of 3G network development, 3G network coverage is small, its network may only cover urban areas, and the development of PCS network of Telecom/China Netcom is relatively mature, and the network has covered urban areas and vast rural areas. Thus, when 3G users roam out of urban areas When the 3G network cannot be used, communication interruption will inevitably affect the user's enthusiasm for using 3G services. If the user has a dual-mode mobile phone with PCS and 3G, the integrated intelligent HLR (Home Location Register) can own the user. The two sets of PCS and 3G data have the same user number. When the user roams out of the city without a 3G network, the dual-mode phone becomes a PCS single standby mode, and the integrated intelligent HLR can return the user PCS according to the specific situation. Network location information, which ensures that user communication is normal, which is to consolidate Telecom/Netcom It is very beneficial to have users and expand the 3G user base at the same time. In the current situation of increasingly fierce competition in telecommunications services, operators can effectively improve the competitiveness of operators by implementing this differentiated service. The technical problem is to provide a method for the PC access by the PCS user and the 3G user to implement the network access, and set the PCS or the 3G network as the preferred network, so that the user can select the access setting when both the PCS and the 3G are available. The network, when the preferred network is unavailable, accesses the secondary network. The present invention provides a method for implementing network access by the PCS user and the 3G user, and includes the following steps: (1) The integrated intelligent home location register HLR is PCS. Assign the same user number to the 3G user, and set a user type that establishes an association between the PCS user information and the 3G user information. (2) PCS and 3G joyful terminal set one of the networks as the preferred access network, use the preferred access network for communication during dual standby, and select another network to transfer to single standby when the preferred access network is unavailable. Several modes of communication; '

(3) After the integrated intelligent HLR receives the routing request of the dual-mode terminal of the dual standby user, if the preferred access network provides the location information, the preferred network location information is returned, and if not, the other network location is determined. Whether the information is available, if available, returns another network location information, is not available, then controls the preferred access network requirements - returns an access failure response. Further, in the step (1), the integrated intelligent IILR stores user information, wherein the PCS user information adopts PSU) and PSNUM as user identifiers, and the 3G user information uses IMS1 and MS1SDN as user identifiers, and the numbers of PSNUM and MSISDN The horse is the same. Further, the user type value in the step (1) is a No. 1 silent standby inter-line free-line user, and the associated relationship is: the user has a pes and 3G m dual standby mode, and needs to be in two Switch between networks, with the same user number. Further, in the step (2), the dual mode terminal sets a 3G network as a preferred access network, or selects a PC S network as a preferred access network. Further, the step (2) further includes: 'If the preferred access network is available again, the automatic handover is to use the preferred access network for communication. Further, when the call mode terminal in step (2) makes a call using one access network, if another access network is connected, the terminal keeps the current call, and the calling party that receives the call sends a busy call. The missed call information is displayed after the current call ends. Further, the case where the preferred network is unavailable includes: no location information, presence of a Purged flag, user arrears, incoming call barring, user shutdown. Further, the routing request in step (3) is a call routing request or a short message routing request. By applying the method of the present invention, PCS and 3G dual standby users with the same user number can be enabled. When the user roams out of the Tfr area and no 3G network is available for access, the dual mobile phone becomes a PCS single standby mode, or PCS. When the network is unavailable, access to the 3G network, thus ensuring normal user communication, which is very beneficial for consolidating the original users of Telecom/Netcom and expanding the 3G user base. This is very beneficial for consolidating the original users of Telecom/Netcom and expanding the 3G user base, and effectively improving the competitiveness of operators.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS In the following, with reference to the accompanying drawings and specific embodiments, the method for implementing network access by the PCS user and the 3G user in the dual standby mode of the present invention is further described in detail. The specific idea of the method of the present invention is: The intelligent HLR allocates the same user number to the PCS and the 3G user, and establishes an association relationship between the PCS user information and the 3G user information, and specifies the preferred access network of the user (a user is preferentially connected to the 3G network); PCS and 3G dual-mode mobile phones use the preferred network to communicate with other users under normal conditions. When the preferred network is unavailable, in the call routing and short message routing response, the location information of the other network is returned to ensure the smooth communication. 1 is a schematic diagram of networking connection when PCS and 3G users access. In the present invention, comprehensive intelligence

The technical requirements for HLR, PCS and 3G dual-mode mobile phones are as follows: Among them, the user information saved by the integrated intelligent HLR includes:

PCS user information, using PSID and PSNUM as user identification;

3G user information, using IMSI and MSISDN as user IDs;

PSNUM and MSISDN have the same number; Among them, PCS and 3G dual-mode mobile phone requirements are as follows: ΐ ΐ 冇 3 G, PJ IS dual f machine capabilities; preset 3G or PCS as a preferred network for caller routing; if a network is not available, then another A network is switched on and becomes a single standby mode; if it is re-available, it automatically switches to the preferred network; if the terminal is in a call, at this time another network session is accessed, the terminal should be able to protect the current call of the temple, the caller The party is busy,

The situation of electricity. In the system implementation, each user in the user database in the HLR has a US nR 'l'YPl ': (user type) ^ L, and the value is a PCS user, a 3G user, a fixed network user, and the like. There is a relationship between the PCS user information and the 3G user information described in the above I 0VR, which means that the US TYPE of the present invention takes a new value network free line user. With this value, the PCS user and the 3G user are locked. According to the new user type value, the system first checks whether the preferred network location information is normal. If the location information is abnormal, it checks whether the user is a free-line user. If the user is a free-line user, check the location of the secondary network. information. According to these technical requirements, users who have PCS and 3G' dual-mode mobile phones but use the same-user number can communicate with other users under the normal network, and when the preferred network is unavailable, in the call routing and short message. In the routing response, return the location information of the other - network to ensure the smooth communication. The integrated intelligent HLR centrally manages the 3G network and the PCS network household information. For example, if the user prefers to access the 3G network and the user roams to the area covered by the 3G network and the PCS network, the user preferably accesses the 3G network to communicate with other users, and the user Roaming out the 3G network into the area covered by the individual PCS network, the user uses the PCS network to communicate with other users. The integrated intelligent I II .R can return the correct location information according to the specific roaming situation of the user to ensure normal communication. The integrated intelligent HJLR specific business process is as follows in the three cases shown in Figure 2, Figure 3, and 3⁄4. (1) Business processes under normal conditions. Figure 2 illustrates a flow chart of a PCS user dialing the 3G number of the dual mode handset 1 under normal conditions. Step 201: The PCS user calls the 3G number of the mobile phone B to the integrated intelligent HLR. Sending a request routing information message; Step 202: The integrated intelligent HLR determines that the called number belongs to the 3G network, and sends a 3GMAP message to the called MSC/VLR of the 3G network, requesting to provide a roaming code, and the user number in the message is routing information. The outgoing number in the request; Step 203: The called party roams back to the roaming number; Step 204: The integrated intelligent HLR returns a routing response to the gateway.

(2) The 3G network is not available, but the business process available on the PCS network. Figure 3 illustrates the 3G number of the 3G subscriber dialing the mobile phone B, but the integrated intelligent HLR finds that B is unavailable in the current 3G network and is available in the PCS network. Step 301: The 3G user calls the 3G number of the dual-mode mobile phone B to send a routing information message to the integrated intelligent HLR. Step butterfly 302: The integrated intelligent ULR determines that the called number belongs to the 3G network, if the called party has the following status on the 3G network. If the abnormality is obtained, the associated number of the called party, that is, the PCS weight is queried, and the roaming number is requested by sending the PI1SMAP message to the called IGW/VLR of the CS network. The user number in the message is the associated number of the calling number in the routing information request; The status abnormalities include: no location information, presence of a Purged flag, user arrears, incoming call barring, user shutdown, etc. Step 303: The called party roams to return the roaming number to the integrated intelligent HLR. Step 304: The integrated intelligent I-ILR returns routing information to the gateway office. (3) The process of failure of the 3G network ^ > ^ ^ seeking roaming number, Figure 4 illustrates the 3G number of the 3G user dialing the dual-mode mobile phone B, but the request for roaming number failure in the 3G network. Step 401: The 3G user calls to dial the 3G: weight of the dual-mode mobile phone B, and sends a request routing information message to the integrated intelligent HLR. Step 402: The integrated intelligent HLR sends a request for providing a roaming number to the MSC/VLR of the 3G network. (using a 3G weight); Step 403: The MSC/VLR of the 3G network sends a roaming number unavailability message to the integrated intelligent back-to-back number; Step 404: The integrated intelligent I-IR sends a request for providing a roaming number to the IGW/VLR of the PCS network (^ PCS number); Step 405: The IGW/VLR of the PCS network returns to the integrated intelligent i'ULR ¹ ;-code; Step 406: The integrated intelligent HLR returns routing information to the gateway, and, in addition, for the short message routing service, the normal situation Next, the MSC number of the 3G network is returned in the short message routing response, and if the MSC number of the 3G network is invalid, the 1GW number of the PCS network is returned.
