A system and method of supporting packet-switched handover of a mobile station (MS) from a GERAN/UTRAN cell to a Generic Access Network (GAN) cell within a GAN. If the MS is within coverage of the GAN cell, the MS registers within the GAN triggering initiation of the packet-switched handover from the GERAN/UTRAN cell to the GAN cell. A preparation phase is then conducted for executing the packet-switched handover. The preparation phase includes identifying the MS context as part of the preparation phase and activating the GA-PSR TC towards the MS. Next, the packet-switched handover is executed, resulting in the MS switching to GAN mode. The MS then begins transferring packets via the GAN cell. The system and method also supports a packet-switched handover from the GAN cell to the GERAN/UTRAN cell.

A bearer suspension method, a bearer resumption method, and a gateway agent are provided. The bearer suspension method includes the following steps. A gateway agent receives a Bearer Suspend Request sent by a mobility management entity (MME) when a user equipment (UE) is handed over from an evolved universal mobile telecommunications system (UMTS) terrestrial radio access network (EUTRAN) to a global system for mobile communications (GSM)/enhanced data rates for GSM evolution (EDGE) radio access network (GERAN). A bearer that needs to be suspended is suspended according to the request. The bearer resumption method includes the following steps. In a process of handover of a UE from a GERAN to an EUTRAN or tracking area update (TAU) or Service Request, the gateway agent receives a Bearer Resume Request sent by an MME. A bearer that needs to be resumed is resumed according to the request.

A domain switching process of the continuity of a single radio channel voice service comprises that an UE switches in an IMS domain from an LTE/SAM network, the LTE/SAM networking initiates the switching request from the LTE/SAM to a CS domain after building up a conversation with far-end nodes, a target GERAN/UTRAN sends the switching finish message to a VMSC when the UE is switched in the target GERAN/UTRAN of the CS domain, the VMSC sends the MAP sending finish signal message to an S-IWF to inform the S-IWF that the UE has switched in the CS switch-in network from the LTE/SAE network, an VCC AS is informed to release the VCC AS of the conversation to the IMS network resource of the LTE/SAE network after the UE sends the switching finish message or after the S-IWF has received the MAP sending finish signal message. And the single radio channel voice service can return back to the original conversation channel according to the original conversation resource when the UE switching is failed.

The present invention relates to a method and an apparatus for employing an embedded subscriber identity module (hereinafter referred to as eSIM) to apply a policy such as a subsidy policy to, activate, deactivate, add to, update, and delete a user profile in a mobile communications network. The present invention enables a mobile device to determine whether to host the policy of a new service provider when it changes the present service provider or to perform a lock for prohibiting the policy change, and to change the profile related to the determination. The present invention also enables a mobile device to replace the policy related to the service provider by applying the policy, or to employ eSIM so as to activate, deactivate, revise, add, or delete the rules of the policy related to the service provider. The present invention provides various examples of hosting and applying the policy and various examples of activating, deactivating, revising, adding, deleting the policy rules so as to make eSIM identify the subscriber as the existing subscriber identity module. The invention also enables the device or eSIM to be reused when changing the service provider throughout the life cycle thereof without limiting the use of eSIM to a single service provider. The invention also provides a method for locking the policy applied per service provider, and the use of eSIM when changing to another service provider by the policy per service provider. The present invention also provides a method for checking the criteria of decision and verifying the power of decision when administering the policy rules and eSIM through deleting, adding, revising, activating, and deactivating the profile management plan and policy rules by applying the service provider's policy. Thus the present invention enables the device to host a new service provider's policy for communicating therewith when changing from the existing service provider to the new service provider, or when the government changes the service provider for an M2M device related to the electricity, infrastructure, etc. under an environment such as EUTRAN (Evolved Universal Terrestrial Radio Access Network) or UTRAN (Universal Terrestrial Radio Access Network)/GERAN(GSM/EDGE Radio Access Network). The present invention also is advantageous in that if the change of a service provider is not allowed according the policy of the existing service provider, the information related to communication and the security information are set revised safely by locking, thus enhancing the communication efficiency and security. The present invention also enables the device to verify the power of the user or to revise safely the information of eSIM for adding, revising, deleting, activating, and deactivating the policy rules for managing the operation profile for administration of the policy of the service provider under an environment such as EUTRAN(Evolved Universal Terrestrial Radio Access Network) or UTRAN(Universal Terrestrial Radio Access Network)/GERAN(GSM/EDGE Radio Access Network), thus enhancing the communication efficiency and security.

The invention discloses a method that includes, during an ongoing call of a wireless user terminal in one of a circuit switched domain or a packet switched domain, initiating a handover procedure; setting parameters allowing the other domain to determine the actual resources needed to continue the call in the other domain, sending an indication of these parameters towards a network element of the other domain and completing the handover procedure. When the ongoing call is in the circuit switched domain completing the handover procedure results in handing over the ongoing call to the packet switched domain, and when the ongoing call is in the packet switched domain completing the handover procedure results in handing over the ongoing call to the circuit switched domain. For example, the circuit switched domain may be a GERAN network and the packet switched domain may be an E-UTRAN (LTE) network. In the GERAN network the handover procedure may be accomplished at least in part through a Gs interface between a mobile switching center and a serving general packet radio system support node and/or through a Gb interface between a base station system and the serving general packet radio system support node. The handover procedure is accomplished at least in part by signaling conducted over an S3 interface between the serving general packet radio system support node of the GERAN network and the mobility management entity of the E-UTRAN network.

This invention describes a method for a cell reselection by a mobile station from a serving GERAN cell supported by a GSM/EDGE (global system for mobile communications/enhanced data rates for GSM evolution) radio access network (GERAN) to a UTRAN cell supported by a universal terrestrial radio access network (UTRAN). According to a first embodiment of the invention, the intended intersystem reselection behavior is reached without signaling changes. This can be a preferred mode for early implementations because signaling changes always take a longer time to reach the products on the field (both mobile and network updates are normally required). According to a second embodiment of the invention, the flexibility of signaling changes is used for an advantage.
