Problems solved by technology

That is to say, if the current call message flow is not revised and changed from using UDT messages to XUDT messages, then this method cannot actually be used;
[0049] (2) Even if the modification described in (1) is made to the current call message flow, before the hop counter value of the waiting XUDT message is reduced to 0, there will still be multiple message loops between the two mobile networks, which means It means that there will be many unnecessary inter-network intercommunication messages between two mobile network operators, resulting in unnecessary settlement fees and increasing the operating costs of operators

Embodiment Construction

[0074] The technical solution of the present invention will be described in more detail below with reference to the drawings and embodiments.

[0075] The invention provides a calling method when using the mobile number portability service, which can prevent MNP call message looping, including:

[0076] After the GMSC receives the incoming call message (usually an IAM message, other messages are not excluded in actual application) sent by other home networks, it obtains the RN information of the called user from the incoming call message, and sends the message to the MNP of the local network -SRF / NPDB sends an SRI message, carrying the obtained RN information of the called user in the SRI message;

[0077] After the MNP-SRF / NPDB receives the SRI message, it finds the RN information of the called user in this NPDB, and if the found RN information is inconsistent with the RN information carried in the SRI message, then The SRI message is discarded.

[0078] Wherein, the RN inf...

Abstract

The invention discloses a calling method when applying mobile number portable service, comprising that after receiving exchange-in message from other home networks, the gateway mobile switching center obtains routing number information of the called from the exchange-in message, and sends route inquiry information to a mobile number portable signaling relay function / number portable database MNP-SRF / NPDB supported by the local network, wherein the inquiry message is provided with the obtained routing number information of the called; after receiving the routing inquiry information, the MNP-SRF / NPDB finds out the routing number information of the called in the local NPDB, if the routing number information is not in accordance with the routing number information provided in message inquiry, discards the routing inquiry message. The invention is capable of avoiding message cycle generation problem in mobile network while implementing mobile number portable service.

Description

technical field [0001] The invention relates to the field of mobile communication, in particular to a calling method when a mobile number portability service is applied. Background technique [0002] In order to make better use of network resources and promote reasonable competition. At present, many standardization organizations have formulated relevant standards for Mobile Number Portability (MNP), and the mobile communication markets of various countries have also introduced mobile number portability services one after another. [0003] The mobile number portability service in 3G is mainly defined by the 3GPP 22.066 and 3GPP 23.066 protocol specifications, and the number portability implementation method of the GSM (Global System for Mobile Communications, Global System for Mobile Communications) network is basically the same. According to the description of the agreement, MNP functions include SRF (Signaling Relay Function) mode and IN mode. The SRF method adopts MAP-r...
