Technical field
The present invention relates to the communications field, relate in particular to a kind of method that realizing period position upgrades in the system of packet switch domain access situation Imitating circuit switching domain signaling.
Background technology
(this network configuration is called CS over PS to packet switch (PS:Packet-Switch) territory access situation Imitating circuit switching (CS:Circuit-Switch) domain signaling, be called for short CSoPS) be by third generation partner program (3rd Generation Partnership Project, abbreviation 3GPP) a kind of CS network architecture based on the PS access that proposes, built in PS access situation, utilized existing CS core network that the network platform of business is provided.
in the CSoPS network architecture, access does not re-use the base station platform in traditional CS territory, but provide access capability by the PS network, such as WLAN (Wireless Local Area Network), WiMax, the PS networks such as LTE (Long Term Evolution), user terminal (UE:User Equipment) uses the PS access capability to access these PS networks, and set up the PS Deta bearer, then encapsulation CS network signal and the CS network media send to a gateway device on the PS Deta bearer, be called IWF (InterWorking Function), after the CS network signal and the CS network media of being packed by the PS Deta bearer that IWF will receive, CS network signal and the CS network media are unpacked out send to the CS core network, thereby realize reusing existing CS Network, for the CS core network, IWF is just as a base station platform.
Fig. 1 is based on the CSoPS framework schematic diagram of LTE access, has described UE in LTE access situation, realizes reusing the framework schematic diagram of CS core network business.In this framework schematic diagram, the actual access of UE be the LTE network, in this network, the network element relevant to CSoPS is Mobility Management Entity (MME:Mobility Management Entity) and grouped data network gateway (P-GW:PacketData Network Gateway), MME is responsible for the relevant part of mobile management in the PS signaling, comprise access control, obtaining etc. of terminal positional information and state, P-GW is responsible for the foundation of PS Deta bearer and the transmission of data.UE is after access LTE network, and request LTE network is set up Deta bearer, and this carries between UE and P-GW, and by this Deta bearer, UE can be mutual with IWF, thereby set up the data tunnel between UE and IWF.In UE and the mutual process of IWF, IWF also can ask the LTE network to set up the Deta bearer of UE, thereby also can set up the data tunnel between UE and IWF.Namely the carrying and on the tunnel can be that UE initiatively sets up, can be also that IWF initiatively sets up, only have due to UE in the situation that has Deta bearer could and IWF mutual, be that UE initiatively sets up or the PS network is initiatively set up when UE accesses so have at least data to carry.By the encapsulation of the data tunnel set up, UE can transmit any type of protocol data, comprises CS signaling and CS media data.In this figure, the CS signaling of UE and CS media data are by a data tunnel transmission, and data tunnel transmits but also can pass through respectively independently.
This framework schematic diagram is described take access network as the LTE network, but can be also other PS networks, and basic principle is identical.
Fig. 2 is the implementation method flow chart that in existing CS network, period position upgrades, after having described UE access CS network, the periodic location update message that sends, to inform also accessibility process of core net UE, the CS network is when disposing, period position just has been configured in CS core network and all base station platform update time, this period position update time and UE are irrelevant, namely the period position of all UE is all identical update time, the time that wherein configures in all base station platforms all is slightly smaller than the time of core net configuration, to hold the time difference in message transmitting procedure, specifically comprise the steps:
In the CS network, base station platform informs that UE, UE are initially receiving period position during update time by broadcast with the period position in base station platform update time, the start-up period position renewing timer by access CS network for step 201, UE;
Step 202, UE judge that periodical position renewing timer is overtime;
Step 203, UE send location update message to the base station platform at place, then restart periodical position renewing timer;
Step 204, base station platform are received location update message, are transmitted to the CS core network, thereby the CS core network can know that this UE is also in this network.
Fig. 3 is the implementation method flow chart that in existing CSoPS framework, period position upgrades, described UE by CSoPS framework access CS network after, the periodic position that sends is upgraded, to inform also accessibility process of core net UE, existing method is simulation CS network existing techniques in realizing fully, and the configuration of the period position update time during network design is identical with the CS network, is that base station platform changes IWF into, repeat no more, specifically comprise the steps:
Step 301, UE are by CSoPS framework access CS network, UE is mutual with IWF in this process, IWF informs UE period position update time by the registration message of response UE, and UE is receiving period position during update time, the start-up period position renewing timer;
Step 302, UE judge that periodical position renewing timer is overtime;
If the Deta bearer that is used for transmission CS signaling of setting up before step 303 UE with and on data tunnel be released, UE asks the PS network to set up Deta bearer again, and sets up data tunnel with IWF with transmission CS signaling in this carrying;
Step 304～305,203～204 identical with Fig. 2, just base station platform has changed IWF into.
As from the foregoing, it is to simulate CS network prior art substantially that period position in existing CSoPS framework upgrades, but the UE of this moment is actual is the UE of PS, it has more Secretary of period position equally in the PS territory, and the period position update mode in simple analog CS territory can be wasted the electric power resource of interface-free resources and terminal.
