Description
Technical field
The present invention relates to communication technical field, relate in particular to the method, network, equipment and the system that obtain, send ID.
Background technology
The intercommunication of 3GPP evolvement network and non-3GPP network is the much-talked-about topic that current standardization body is discussed.Wherein of greatest concern is the intercommunication of 3GPP evolvement network and eHRPD (evolution High Rate Packet Data) network.
See also Fig. 1, in the framework of 3GPP network and eHRPD network interworking, between 3GPP network and eHRPD network, increased by two interfaces: first interface is the S101 interface, and second interface is the S103 interface.Wherein,
The S101 interface is the interface between MME and the eAN (evolution Access Network); Its essence is a tunnel; Signaling between forwarding terminal and the objective network and data are (just under discussion; Might also can pass data), accessory terminal carries out pre-registration or switches to objective network from source network at objective network.
The S103 interface is the interface between Serving Gateway and the HSGW (HRPD gateway), and the data that are used to transmit the delay of 3GPP evolvement network send to the terminal through the eHRPD network then to the eHRPD network.
The dual-mode terminal of supposing LTE/HRPD is the dual-mode terminal of single-emission and double-receiving.In this case, when the terminal on a network transceive data time, it can not carry out the work of registration, authentication or session negotiation simultaneously on the another one network.When the result causes terminal across accesses technical to switch, must register earlier, work such as authentication or session negotiation.These processes need several seconds usually, cause transfer of data to interrupt, and have greatly influenced the quality of service of real time business in handoff procedure.In order to reduce the terminal that real time business switches, the notion of " pre-registration " has been proposed.Promptly when terminal still also at source network the time, the terminal is transceive data on one side, on one side through source network and work such as S101 interface and objective network execution registration, authentication or session negotiation.Really carry out to begin immediately in the objective network transceive data when inter-network is switched at the terminal, therefore at utmost reduced inter-network service switchover break period.
After pre-registration was carried out at the terminal, before the terminal really switched to objective network, terminal and objective network can carry out Signalling exchange through source network and S101 interface as required at any time.For example, when the QoS configuration information changed, terminal and objective network be consulting session information again.
All there is a S101 Session (session) ID in each S101 tunnel as sign.The IMSI (international mobile subscriber identification code) that adopts the terminal at present is as the S101 session id.Adopting IMSI is that the S101 session id overall situation is unique as an advantage of S101 session id, therefore when network entity changes, need not change the S101 session id, has reduced the work that the S101 session id distributed and safeguards when network entity switched.
In current HRPD standard, can pass through the IMSI information that device authentication (through the A12 interface) obtains the terminal.HRPD network IMSI is used to select to be connected to the PDSN of packet-based core networks, also is used for the mobile station identification of A9 and A11 interface message simultaneously, and PDSN identifies the grouping data conversation of distinguishing different user with this.But the inventor finds in realizing process of the present invention: device authentication is not the essential function of eHRPD network.Not under the situation of support equipment authentication, eAN can't obtain the IMSI at terminal, thereby can't produce the S101 session id based on IMSI at eHRPD.Further; Because device authentication is not the essential function of HRPD and eHRPD network; At eHRPD not under the situation of support equipment authentication; AN or eAN can't obtain IMSI and other ID of UE, make PDSN or HSGW can't discern the grouping data conversation of existence and set up new grouping data conversation, cause time-delay and loss of data.
