1.3 Mobility Management

1.3.1 GBFD-0301 Location Updating

Availability


Summary

To ensure that services such as the paging can be processed normally, the network needs to

know the information about the location of the MS. The MS registers to the network throughthe location updating procedure. In this way, the VLR and HLR keep track of the locationinformation about the MS, thus ensuring the normal communication of MSs.

BenefitsLocation updating is a basic feature for the operators to provide the CS speech services.

Description

The location updating procedure is the signaling procedure for the MS to update the locationinformation on the network. This ensures that the location information about the MS stored inthe HLR and VLR is consistent with the actual location information about the MS.

The general location updating procedure is as follows: The MS initiates the access requestwith the location updating as the access cause; the network side allocates a signaling channelfor the MS; the MS sends a location updating request on this signaling channel; the NSS sidedetermines whether to accept the location updating request based on the identity of the MS.

In different scenarios, three types of specific location updating procedures are initiated:normal location updating, periodic location updating, and IMSI attach location updating.

Normal location updating

When the location area of the MS changes, the MS initiates the normal location updatingprocedure. During the normal location updating procedure, the network side may initiateother supplementary procedures, such as the classmark interrogation, identificationrequest, authentication, and ciphering mode setting.

Periodic location updating

When timer T3212 expires, the MS initiates the periodic updating procedure. The valueof T3212 is provided by the network in the system information type 3 message. The MSresolves this system information message to obtain the value of the T3212 timer.

IMIS attach location updating procedure

The IMSI attach location updating is a complement to the IMSI detach procedure. Thenetwork uses the system information type 3 message to indicate whether the IMSI attachand IMSI detach are allowed. If the network indicates that the IMSI attach and IMSIdetach are required, the MS triggers the IMSI attach procedure when the IMSI isactivated. When the MS activates the IMSI or the MS has moved from a non-coveragearea to a coverage area, the IMSI attach procedure is triggered if the IMSI attach is

allowed and the stored location area of the MS is the same as the location area of thecurrent serving cell.

Location updating ensures smooth communication by updating the information about the

location of MSs in the VLR and HLR in real time.

1.3.2 GBFD-0302 IMSI Detach

Availability


Summary

After the IMSI is detached, the subscriber is marked as an invalid subscriber by the network.Then, the network does not send any paging message to this subscriber.

Benefits

IMSI detach is a basic feature for the operators to provide the CS speech services.

Description

IMSI attach and detach are IMSI-specific procedures. When an MS is powered off, it sendsthe network the last message containing the detach request. On receiving this message, theMSC/VLR sets the subscriber status to invalid. Then, the network does not page thissubscriber.

During the IMSI detach, the subscriber status is set only on the MSC/VLR but not on theHLR. After the MS powers on again, the MS performs the IMSI attach procedure if thecurrent location area of the MS is the same as the location area registered before the MS ispowered off. Otherwise, the MS performs the normal location updating procedure to make thelocation information stored in the HLR and VLR the same as the actual location area of theMS.

The network informs the MS of whether the IMSI attach or detach is allowed by sending the

system information type 3 message.

1.3.3 GBFD-0303 Paging

Availability


Summary

The network instructs the MS to access the network as the called party through the paging

procedure to complete the call establishment.

Benefits

Paging is a basic feature for the operators to provide the CS speech services. The pagingalgorithm determines the paging efficiency of the GBSS. Excellent pag ing algorithms providethe following benefits:

The paging processing capability is one of the indexes that indicate the system capability.Huawei GBSS paging algorithm guarantees the paging processing capability whilemaintaining the paging efficiency and reducing the paging load.

Prevents the paging from being missed so that the subscriber can receive calls. Thus,

complaints decrease and user satisfaction increases.

Description

Paging procedure: To answer the call timely, the MS in idle state listens to the paging channel

all the time. If there is a paging message to the MS, the MS responds to the paging andcompletes the subsequent procedure as a called party.

The pagings are classified into PS pagings and CS pagings. When there is downlink data to be

transferred to the MS, the SGSN initiates the PS paging procedure. If packet common controlchannel (PCCCH) is configured, the PS paging message is transmitted on PCCCH. If PCCCHis not configured, the PS message is transmitted on PCH.


26/367




The CS paging message is sent on PCH. When a call arrives at the MSC that serves the MS,

the MSC determines the location area of the MS and then sends the paging message to all

BSCs in this location area. The BSCs determine the paging cell based on the location area anddetermine the paging group that the MS belongs to based on the IMSI. Then, the BSC sendsthe paging message to the corresponding BTS. The BTS then sends the paging message to the

MS on the assigned PCH.

Huawei GBSS supports the following three standard paging modes :

Common paging mode

The paging message is transmitted on only the configured PCH and the IMSI definedchannel.

Complete paging mode

When an MS group is informed in this mode, the paging message of this group may betransmitted on any PCH of the same timeslot. When dynamic change of PCHconfiguration occurs, this mode prevents paging message loss.

Spaced paging modeThe BSS adds the paging message of a group to another paging channel to avoidtemporary overload. That is, the MS receiving common paging messages on channel Ncan get the paging message on the next paging channel N+2.

Huawei GBSS supports paging message queuing, paging retransmission, simultaneousprocessing of multiple pages, and paging flow control. This can effectively improve andensure the paging capacity of the BSC.

Paging message queuing

The transmission of paging messages on the Um interface is limited on the basis ofpaging groups. The paging message of one paging group can only be transmitted on thepaging block corresponding to the paging group. Therefore, the paging message queuing

is implemented on the BTS. That is, during the period when the BTS waits fortransmission, the paging messages from the BSC are buffered on the BTS. Upon thetransmission, the BTS selects the appropriate paging messages from the queue totransmit on the corresponding block. If many paging messages have the sametransmission priority, the BTS processes these messages according to the FIFO principle.

Paging retransmission

Generally, both the CN and BSS of the GSM network allows paging retransmission. Atwo-level retransmission mechanism is provided. One retransmission is initiated by theCN to handle long intermittence during the paging transmission. The retransmissioninitiated by the CN takes a relatively long time. The other retransmission is implemented

on the BTS. The retransmission initiated by the BTS takes a relatively short time. Hence,the two-level retransmission mechanism reduces the signaling load on the Abis interface

and A interface. Huawei BSS supports the paging retransmission. That is, when there isno paging message or immediate assignment message to be transmitted on thecorresponding sending block, the paging messages that are already transmitted areretransmitted on this sending block. The maximum number of paging retransmissionscan be specified by the system parameter.

Simultaneous processing of multiple paging messages

Each paging command from the BSC comprises only one paging message sent to oneMS, but each paging request on the Um interface may pack a maximum of four pagingmessages sent to four different MSs. Therefore, to improve the efficiency of the pagingprocessing, the number of paging commands to the MS included in the paging messageon the Um interface should be as many as that is specified. In detail, a maximum of fourpaging messages can be included. When the sending block of a paging group is polled,

the BTS searches for the paging messages to be transmitted in the paging queue
