Embodiment 1

[0058] In this embodiment, when the UE initiates a VoIP call in the LTE evolved system, the source MME and / or UPE will determine the session priority of the current VoIP session according to the operator's policy and user subscription information. Through the VoIP session level, the source The MME and / or UPE can determine the corresponding domain transfer required flag (Domain Transfer required flag), and send it to the target SGSN through an inter-system forwarding handover message, and the target SGSN receives the forwarding handover message carrying the domain transfer required flag, and sends The domain switching requirement indication is sent to the target BSC, and the target BSC decides whether to perform domain switching according to the received domain switching requirement indication, capability information of the target cell, and its current dynamic conditions.

Embodiment 2

[0078] In Embodiment 1, when the UE initiates a VoIP call in the LTE evolved system, the source MME and / or UPE determines the session level of the current VoIP session according to the operator's policy and user subscription information, and the current VoIP session level, the source MME, and / or the UPE determines the corresponding domain switching requirement identifier, and sends it to the target SGSN through the forwarding and switching message between systems. Session level, the session level information of the current VoIP session is sent to the target SGSN through the inter-system forwarding switching message, and the target SGSN receives the forwarding switching message carrying the session level information, and sends the session level information of the current VoIP session to the target BSC, The target BSC judges whether to perform domain switching according to the received session level information, capability information of the target cell and its current dynamic con...

Embodiment 3

[0086] In this embodiment, when the UE initiates the handover process of the VoIP session to GERAN in the LTE evolved system, the source MME and / or UPE sends a forwarding handover message between systems to the target SGSN, carrying the subscription information of the UE, and the target SGSN Receive the forwarding handover message carrying the subscription information of the UE, send the subscription information of the UE to the target BSC, and the target BSC judges whether to perform domain switching according to the received subscription information of the UE, the capability information of the target cell, and its current dynamic conditions.

[0087] Figure 7 It is a schematic flowchart of a method for switching communication services in Embodiment 3 of the present invention. see Figure 7 , the process includes:

[0088] Step 701, the UE periodically reports a measurement report message to the ENB;

[0089] Step 702, the ENB judges the target BSC that the UE should swit...

Abstract

The invention discloses a method of switching communication service, comprising packet commutative field switch and packet switching and circuit commutative field switch. The method comprises that: in the packet commutative field switch, an object base station controller receives switching indication information of the packet switching and the circuit commutative field switch from a source moving management entity and / or a user surface entity; after the object base station controller completes the packet commutative field switch, the object base station controller determines to switch from the packet switching to the circuit commutative field according to the ability of the object district, the dynamic condition and the indication information of the received packet switching and the circuit commutative field switch. The invention also discloses a system of switching communication service. According to the invention, the high-side user equipment is ensured to obtain the resource preferentially, service quality requirement of the communication service of the high-side user equipment is ensured, thereby increasing satisfaction degree of the user.

Description

technical field [0001] The invention relates to communication switching technology, in particular to a method and system for switching communication services. Background technique [0002] For systems such as World Interoperability for Microwave Access (WiMAX, World Interoperability for Microwave Access) with a data rate index of 50M uplink and 100M downlink, in order to ensure the competitiveness of wireless technology in the next 10 years, the 3rd Generation Mobile Communication Standardization Partnership Project (3GPP, The 3rd Generation Partnership Project) standards organization has launched a new-generation network system architecture evolution / long-term evolution plan (SAE / LTE, System Architecture Evolution / Long Term Evolved). The SAE / LTE network evolution project is based on High Speed ​​Downlink Packet Access (HSDPA, High Speed ​​Downlink Packet Access), on the basis of the original HSDPA and enhanced uplink (EUL, Enhanced Uplink) and other systems, the delay, user...
